    1996-06-01

    The purpose of this project is to compare structural ceramic materials proposed for use in the air heater of a coal fired high temperature furnace (HITAF) for power generation. This new generation of coal fired power plants with increased efficiency, fewer emissions and lower costs are currently being developed under the Combustion 2000 program funded by Pittsburgh Energy Technology Center (PETC). Large improvements in efficiencies will require a change to combined cycles that employ gas turbines and steam turbines (Brayton Cycle) instead of exclusive reliance on steam turbines. Extremely high temperature working fluid is required to boost the efficiency, and the result is that the power plant sub-systems will be exposed to much more corrosive environments than in the present systems. The uses of ceramic heat exchangers are being investigated for those new power plants because of the potential for producing a clean, hot working fluid for the gas turbine.

    Full Text Available Supporting large amounts of spatial data is a significant characteristic of modern databases. However, unlike some mature relational databases, such as Oracle and PostgreSQL, most of current burgeoning NoSQL databases are not well designed for storing geospatial data, which is becoming increasingly important in various fields. In this paper, we propose a novel method to provide R-tree index, as well as corresponding spatial range query and nearest neighbour query functions, for MongoDB, one of the most prevalent NoSQL databases. First, after in-depth analysis of MongoDB’s features, we devise an efficient tabular document structure which flattens R-tree index into MongoDB collections. Further, relevant mechanisms of R-tree operations are issued, and then we discuss in detail how to integrate R-tree into MongoDB. Finally, we present the experimental results which show that our proposed method out-performs the built-in spatial index of MongoDB. Our research will greatly facilitate big data management issues with MongoDB in a variety of geospatial information applications.

    To examine selection criteria for Parent-to-Parent support parents trained to provide support to other parents of children with disabilities. Ten leaders of Parent-to-Parent programmes participated in telephone interviews to explore attributes associated with parents selected to be trained as support parents. Qualitative analysis reveals parents deemed "ready" to become support parents, build relationships, exhibit positivity, build capacities, have good communication skills and a future orientation and feel the need to give back. An additional set of attributes we have named, "red flags" are associated with parents not suitable to provide support are also presented. Parent-to-Parent support parents are informally identified by a set of characteristics that can be operationalized for screening purposes. Findings provide support for the positive influence of the peer support relationship and identify the need for a measure of parent "readiness" to assist in the recruitment of quality support parents for the Parent-to-Parent organization. © 2017 John Wiley & Sons Ltd.

    Addressing suboptimal breastfeeding initiation and duration rates is a priority in the United States. To address challenges to improving these rates, the voices of the providers who work with breastfeeding mothers should be heard. Research aim: The purpose of this study was to explore lactation consultants' perceived barriers to managing early breastfeeding problems. This qualitative study was conducted with a grounded theory methodological approach. In-depth interviews were conducted with 30 International Board Certified Lactation Consultants across Florida. Lactation consultants were from a range of practice settings, including hospitals, Special Supplemental Nutrition Program for Women, Infants, and Children clinics, private practice, and pediatric offices. Data were digitally recorded, transcribed, and analyzed in Atlas.ti. A range of barriers was identified and grouped into the following categories/themes: indirect barriers (social norms, knowledge, attitudes); direct occupational barriers (institutional constraints, lack of coordination, poor service delivery); and direct individual barriers (social support, mother's self-efficacy). A model was developed illustrating the factors that influence the role enactment of lactation consultants in managing breastfeeding problems. Inadequate support for addressing early breastfeeding challenges is compounded by a lack of collaboration among various healthcare providers and the family. Findings provide insight into the professional management issues of early breastfeeding problems faced by lactation consultants. Team-based, interprofessional approaches to breastfeeding support for mothers and their families are needed; improving interdisciplinary collaboration could lead to better integration of lactation consultants who are educated and experienced in providing lactation support and management of breastfeeding problems.

    2015-02-01

    Community Men's Sheds (CMS) have been a unique approach within Australia for addressing and promoting men's health and well-being issues by providing biopsychosocial support. Given the decline of traditional religious influence, and the contemporary understanding of 'spirituality', it can be argued that CMS may also develop and demonstrate characteristics of a communal spirituality. This research aimed to explore the individual and community contribution of CMS in terms of men's health and well-being and subsequently whether CMS programmes satisfied the contemporary and consensus understanding of spirituality. A qualitative case study was undertaken combining both participant observation over a 6-month period and semi-structured in-depth interviews with 21 men of varying ages and occupations attending a Melbourne suburban CMS (Victoria, Australia). Thematic analysis indicated that the CMS provided a number of health and well-being benefits at individual, family, community and public health levels. These included increased self-esteem and empowerment, respite from families, a sense of belonging in the community and the opportunity to exchange ideas relating to personal, family, communal and public health issues. It is concluded that CMS, through the provision of an appropriate spatial context and organizational activities, encourage intra-personal and inter-personal reflection and interaction that subsequently results in men meaningfully, purposefully and significantly connecting with the moment, to self, to others and to their environment-and thus, CMS not only provides biopsychosocial support but can also deliver spiritual support.

    Commonly used drugs in hospital setting can cause QT prolongation and trigger life-threatening arrhythmias. We evaluate changes in prescribing behavior after the implementation of a clinical decision support system to prevent the use of QT prolonging medications in the hospital setting. We conducted a quasi-experimental study, before and after the implementation of a clinical decision support system integrated in the electronic medical record (QT-alert system). This system detects patients at risk of significant QT prolongation (QTc>500ms) and alerts providers ordering QT prolonging drugs. We reviewed the electronic health record to assess the provider's responses which were classified as "action taken" (QT drug avoided, QT drug changed, other QT drug(s) avoided, ECG monitoring, electrolytes monitoring, QT issue acknowledged, other actions) or "no action taken". Approximately, 15.5% (95/612) of the alerts were followed by a provider's action in the pre-intervention phase compared with 21% (228/1085) in the post-intervention phase (p=0.006). The most common type of actions taken during pre-intervention phase compared to post-intervention phase were ECG monitoring (8% vs. 13%, p=0.002) and QT issue acknowledgment (2.1% vs. 4.1%, p=0.03). Notably, there was no significant difference for other actions including QT drug avoided (p=0.8), QT drug changed (p=0.06) and other QT drug(s) avoided (p=0.3). Our study demonstrated that the QT alert system prompted a higher proportion of providers to take action on patients at risk of complications. However, the overall impact was modest underscoring the need for educating providers and optimizing clinical decision support to further reduce drug-induced QT prolongation.

    Describe social goods and services for which hospices assist patients and families and the resources hospices use to do so. Basic social supports and services not routinely covered by insurers may be needed by terminally ill patients and their families. Little is known about hospices' provision of such social supports and services. A 2014-2015 cross-sectional survey of hospices nationwide. Participating hospices had been in operation for at least 3 years and were located in any of the 50 states or District of Columbia. Hospices were surveyed about availability and sources of internal funds and referral to obtain basic social supports for patients. Descriptive statistics, bivariate analysis, and categorization were used to describe hospice practices. Measures included frequency and nature of goods and services provision in the prior year; and extent to which hospices used internal funds or community referral for goods and services. Over 80% (n = 203) reported internal funds covered services not reimbursed by insurers; 78% used funds in last year. Hospices used internal funds for food (81.7%), shelter (57.8%), utility bills (73.5%), and funeral costs (50%). Hospices referred patients/families to community organizations to obtain a similar range of services, including transportation, clothing, linens/towels, furniture/appliances, home repairs, and caregiver support. Hospices are using internal resources and accessing community resources to provide patients with basic social needs not routinely covered by insurance.

    Healthcare practitioners in Alberta and across Canada have varying levels of access to information resources depending on their institutional and professional affiliations, yet access to current health information is critical for all. To determine what information resources and services are provided by Albertan and Canadian professional health associations to their members. Representatives of professional colleges and associations were interviewed regarding information resources and services offered to members and perceptions of their members' information needs. National-level associations are more likely to provide resources than provincial ones. There is a clear distinction between colleges and associations in terms of information offered: colleges provide regulatory information, while associations are responsible for provision of clinical information resources. Only half of the associations interviewed provide members with access to licensed databases, with cost being a major barrier. There is considerable variation in the number of electronic resources and the levels of information support provided by professional health associations in Alberta and Canada. Access and usage vary among the health professions. National licensing of resources or creation of a portal linking to freely available alternatives are potential options for increasing access and awareness. © 2012 The authors.

    2016-01-01

    The aim of this study was to investigate the correlation between basic life support skills in dentists who had completed the American Heart Association's Basic Life Support (BLS) Healthcare Provider qualification and time since course completion. Thirty-six dentists who had completed the 2005 BLS Healthcare Provider course participated in the study. We asked participants to perform 2 cycles of cardiopulmonary resuscitation on a mannequin and evaluated basic life support skills. Dentists who had previously completed the BLS Healthcare Provider course displayed both prolonged reaction times, and the quality of their basic life support skills deteriorated rapidly. There were no correlations between basic life support skills and time since course completion. Our results suggest that basic life support skills deteriorate rapidly for dentists who have completed the BLS Healthcare Provider. Newer guidelines stressing chest compressions over ventilation may help improve performance over time, allowing better cardiopulmonary resuscitation in dental office emergencies. Moreover, it may be effective to provide a more specialized version of the life support course to train the dentists, stressing issues that may be more likely to occur in the dental office.

    Little research has examined the characteristics of peer support. Pertinent to such examination may be characteristics such as the distinction between nondirective support (accepting recipients' feelings and cooperative with their plans) and directive (prescribing "correct" choices and feelings). In a peer support program for individuals with diabetes, this study examined (a) whether the distinction between nondirective and directive support was reflected in participants' ratings of support provided by peer supporters and (b) how nondirective and directive support were related to depressive symptoms, diabetes distress, and Hemoglobin A1c (HbA1c). Three hundred fourteen participants with type 2 diabetes provided data on depressive symptoms, diabetes distress, and HbA1c before and after a diabetes management intervention delivered by peer supporters. At post-intervention, participants reported how the support provided by peer supporters was nondirective or directive. Confirmatory factor analysis (CFA), correlation analyses, and structural equation modeling examined the relationships among reports of nondirective and directive support, depressive symptoms, diabetes distress, and measured HbA1c. CFA confirmed the factor structure distinguishing between nondirective and directive support in participants' reports of support delivered by peer supporters. Controlling for demographic factors, baseline clinical values, and site, structural equation models indicated that at post-intervention, participants' reports of nondirective support were significantly associated with lower, while reports of directive support were significantly associated with greater depressive symptoms, altogether (with control variables) accounting for 51% of the variance in depressive symptoms. Peer supporters' nondirective support was associated with lower, but directive support was associated with greater depressive symptoms.

    Full Text Available The wetland has a strategic role in national development. The potential uses of the wetland are varied such as for agriculture, fisheries, industries, and forestry. The intensive use of the wetland for agricultural development in Sumatera, Kalimantan, Sulawesi, and Papua through transmigration projects has been run since in 1973. Unfortunately, not all the projects were well developed, causing the social, economic, and physical environmental problems. These problems resulted in the negative impact for the life of the transmigration people. For that reason, the community empowerment for the unlucky transmigration people by handling the physical and non physical aspects is very important. This paper will describe the importance of providing spatial data and information biophysical wetland as an initial step in empowering people who live in the wetland resource.

    Increasing the penetration of distributed renewable sources, including photovoltaic (PV) sources, poses technical challenges for grid management. The grid has been optimized over decades to rely upon large centralized power plants with well-established feedback controls, but now non-dispatchable, renewable sources are displacing these controllable generators. This one-year study was funded by the Department of Energy (DOE) SunShot program and is intended to better utilize those variable resources by providing electric utilities with the tools to implement frequency regulation and primary frequency reserves using aggregated renewable resources, known as a virtual power plant. The goal is to eventually enable the integration of 100s of Gigawatts into US power systems.

    The synergy and linkages between bioregenerative life support systems and the materials produced by in-situ materials processing systems was investigated. Such systems produce a broad spectrum of byproducts such as oxygen, hydrogen, processed soil material, ceramics, refractory, and other materials. Some of these materials may be utilized by bioregenerative systems either directly or with minor modifications. The main focus of this project was to investigate how these materials can be utilized to assist a bioregenerative life support system. Clearly the need to provide a sustainable bioregenerative life support system for long term human habitation of space is significant.

    Social support is associated with improved self-management for people with chronic conditions, such as epilepsy; however, little is known about the perceived ease or difficulty of receiving and providing support for epilepsy self-management. We examined patterns of epilepsy self-management support from the perspectives of both people with epilepsy and their support persons. Fifty-three people with epilepsy and 48 support persons completed a survey on epilepsy self-management support. Of these...

    The effectiveness of and adherence to eHealth interventions is enhanced by human support. However, human support has largely not been manualized and has usually not been guided by clear models. The objective of this paper is to develop a clear theoretical model, based on relevant empirical literature, that can guide research into human support components of eHealth interventions. A review of the literature revealed little relevant information from clinical sciences. Applicable literature was drawn primarily from organizational psychology, motivation theory, and computer-mediated communication (CMC) research. We have developed a model, referred to as "Supportive Accountability." We argue that human support increases adherence through accountability to a coach who is seen as trustworthy, benevolent, and having expertise. Accountability should involve clear, process-oriented expectations that the patient is involved in determining. Reciprocity in the relationship, through which the patient derives clear benefits, should be explicit. The effect of accountability may be moderated by patient motivation. The more intrinsically motivated patients are, the less support they likely require. The process of support is also mediated by the communications medium (eg, telephone, instant messaging, email). Different communications media each have their own potential benefits and disadvantages. We discuss the specific components of accountability, motivation, and CMC medium in detail. The proposed model is a first step toward understanding how human support enhances adherence to eHealth interventions. Each component of the proposed model is a testable hypothesis. As we develop viable human support models, these should be manualized to facilitate dissemination.

    Durable platinum catalyst support materials, e.g. tungsten carbide (WC), tungsten oxide (WOx) and self-synthesized tungsten oxide (WOxs) were evaluated for the use in High-Temperature Proton Exchange Fuel Cells (HT-PEM) based on phosphoric acid doped polybenzimidazole as electrolyte. The support materials and the catalyst loaded support materials were characterized ex-situ by cyclic voltammetry in HClO4, potential cycling, CO-stripping, electron microscopy and X-ray diffraction measurements. The tungsten oxide and tungsten carbide based supported catalysts were compared to High Surface Area Carbon (HSAC), each coated with platinum via the same in-house manufacturing procedures. The in-house manufacturing procedures resulted in catalyst particle sizes on HSAC of 3-4 nm with a uniform distribution. The in-situ Potential Cycling experiments of WOx or WOxs supported catalysts showed much lower degradation rates compared to High Surface Area Carbons. The formation of WOx species on WC was proven by ex- and in-situ cyclic voltammetric studies and thermogravimetric analyses. X-ray diffraction, ex-situ cyclic voltammetry and in-situ cyclic voltammetry showed that WOx is formed from WC as starting material under oxidizing conditions. Finally a 1000 h durability test with WOx as catalyst support material on the anode was done in a HT-PEM fuel cell with reformed methanol on the anode.

    2013-09-01

    Providing and seeking social support are important aspects of social exchange. New communication technologies, especially social network sites (SNSs), facilitate the process of support exchange. An increasing number of health organizations are using SNSs. However, how they provide and seek social support via SNSs has yet to garner academic attention. This study examined the types of social support provided and sought by health organizations on Twitter. A content analysis was conducted on 1,500 tweets sent by a random sample of 58 health organizations within 2 months. Findings indicate that providing informational and emotional support, as well as seeking instrumental support, were the main types of social support exchanged by health organizations through Twitter. This study provides a typology for studying social support exchanges by health organizations, and recommends strategies for health organizations regarding the effective use of Twitter.

    Social support is associated with improved self-management for people with chronic conditions, such as epilepsy; however, little is known about the perceived ease or difficulty of receiving and providing support for epilepsy self-management. We examined patterns of epilepsy self-management support from the perspectives of both people with epilepsy and their support persons. Fifty-three people with epilepsy and 48 support persons completed a survey on epilepsy self-management support. Of these individuals, 22 people with epilepsy and 16 support persons completed an in-depth interview. Rasch measurement models were used to evaluate the degree of difficulty of receiving or providing support often for nine self-management tasks. We analyzed model-data fit, person and item location along the support latent variable and differential person and item functioning. Qualitative methods were used to provide context and insight into the quantitative results. The results demonstrated good model-data fit. Help with seizures was the easiest type of support to receive or provide more often, followed by rides to a doctor's appointments and help avoiding seizure triggers. The most difficult types of support to receive or provide more often were reminders, particularly for taking and refilling medications. While most participants' responses fit the model, responses of several individuals misfit the model. Person misfit generally occurred because the scale items did not adequately capture some individuals' behaviors. These results could be useful in designing interventions that use support as a means of improving self-management. Additionally, the results provide information to improve or expand current measures of support for epilepsy self-management to better assess the experiences of people with epilepsy and their support persons.

    2017-07-16

    Carbon fiber (CF) is widely used as a sludge biofilm support material for wastewater treatment. Carbon nanotubes/carbon fiber (CNTs/CF) hybrid material was prepared by ultrasonically assisted electrophoretic deposition (EPD). CF supports (CF without handling, CF oxidized by nitric acid, CNTs/CF hybrid material) were evaluated by sludge immobilization tests, bacterial cell adsorption tests and Derjaguin -Landau -Verwey -Overbeek (DLVO) theory. We found that the CNTs/CF hybrid material has a high capacity for adsorbing activated sludge, nitrifying bacterial sludge and pure strains (Escherichia coli and Staphylococcus aureus). CNTs deposited on CF surface easily wound around the curved surface of bacterial cell which resulted in capturing more bacterial cells. DLVO theory indicated the lowest total interaction energy of CNTs/CF hybrid material, which resulted in the highest bacteria cell adsorption velocity. Experiments and DLVO theory results proved that CNTs/CF hybrid material is a super support material for sludge biofilms.

    The primary support structure (PSS) is required for mechanical support of reactor module (RM) components and mounting of the RM to the spacecraft. The PSS would provide support and accept all loads associated with dynamic (e. g., launch and maneuvering) or thermally induced loading. Prior to termination of NRPCT involvement in Project Prometheus, the NRPCT Mechanical Systems team developed preliminary finite element models to gain a basic understanding of the behavior of the structure, but optimization of the models, specification of the final design, and materials selection were not completed. The Space Plant Materials team had evaluated several materials for potential use in the primary support structure, namely titanium alloys, beryllium, aluminum alloys and carbon-carbon composites. The feasibility of application of each material system was compared based on mass, stiffness, thermal expansion, and ease of fabrication. Due to insufficient data on environmental factors, such as temperatures and radiation, and limited modeling support, a final materials selection was not made.

  12. Support provider's appraisal detection bias and the efficacy of received support in medical students preparing for an exam.

    Science.gov (United States)

    Knoll, Nina; Schulz, Ute; Schwarzer, Ralf; Rosemeier, Hans Peter

    2006-09-01

    Matching social support to the recipient's needs requires diagnostic sensitivity on the part of the provider. In particular, support needs to be responsive to the recipient's stress-related appraisals to be maximally effective. To assess the impact of bias in interpersonal stress assessment, medical students in 43 dyads reported on their own and each other's stress appraisals, social support, affect and performance during a 5-day preparation period culminating in a multiple choice examination. Less biased perceptions of loss appraisals by support providers within dyads were followed by support transactions associated with lower negative affect and better exam performance among recipients. More biased perceptions of threat appraisals were followed by increases in the recipients' negative affect. Results therefore suggest that support is more effective when the provider understands the recipient's concerns.

    Full Text Available The purpose of this study was to test the support to undermined occlusal enamel provided by posterior restorative composite (FiltekTM P60, 3M Dental products USA, polyacid modified resin composite (F2000 compomer, 3M Dental products, USA., radiopaque silver alloy-glass ionomer cement (Miracle Mix. GC Corp, Tokyo, Japan and Glass Ionomer cement (Fuji IX GP. To test each material, 20 human permanent mandibular third molars were selected. The lingual cusps were removed and the dentin supporting the facial cusps was cut away, leaving a shell of enamel. Each group of prepared teeth was restored using the materials according to the manufacturer′s instructions. All the specimens were thermocycled (250 cycles, 6°C- 60°C, dwell time 30 seconds and then mounted on an acrylic base. Specimens were loaded evenly across the cusp tips at a crosshead speed of 5 mm /minute in Hounsfield universal testing machine until fracture occurred. Data obtained was analyzed using analysis of variance and Studentized- Newman- Keul′s range test. No significant differences were detected in the support provided by P-60, F 2000, Miracle Mix or Fuji IX GP groups. The support provided to undermined occlusal enamel by these materials was intermediate between no support and that provided by sound dentin. Without further development in dental material technology and evidence of its efficacy, restorative materials should not be relied upon to support undermined occlusal enamel to a level comparable to that provided by sound dentin.

    2010-03-01

    This study assessed substance abuse treatment providers' beliefs about empirically supported treatments (ESTs) to determine if providing information about empirical support for interventions would change beliefs. Treatment providers (N=136) completed an interview regarding five interventions with varied empirical support: contingency management (CM), motivational interviewing (MI), relapse prevention (RP), 12-step approaches (TSA), and verbal confrontation (VC). Participants then read primers describing empirical support for each intervention prior to completing a repeat interview. Overall, providers reported positive beliefs about ESTs. Baseline beliefs about empirical support for each intervention were inflated relative to that of expert raters except for CM. After reading the primers, beliefs about efficacy changed in the direction of the experts for all interventions except MI, but continued to be inflated except for CM. Willingness to utilize interventions increased for RP, MI, and CM and decreased for TSA and VC, but remained higher than warranted by empirical support. Copyright 2009.

    Kent de Grey, Robert G; Uchino, Bert N; Smith, Timothy W; Baucom, Brian R W

    2018-01-01

    Provider factors, such as anxiety, may be important in understanding effects of received social support (SS), which are less consistently positive than those of perceived SS. Due to the dyadic nature of support, anxiety on the part of the provider was predicted to influence the effectiveness of received SS. This laboratory study examined effects of SS provider anxiety within unacquainted dyads on cardiovascular reactivity during acute stress. 148 participants were assigned to support roles, and each dyad was randomized to low or high provider anxiety. Results include that SS provider anxiety resulted in greater blood pressure reactivity and less recovery toward baseline diastolic blood pressure within the dyad. Overall, it appears provider anxiety contributes to less effective SS for recipients and that health costs may accompany providing and receiving support under nonoptimal conditions.

    2016-10-01

    This discussion paper poses the question 'What enables or deters Registered Nurses to take up their professional responsibility to support undergraduate nursing students through the provision of clinical education?'. Embedded within many nursing standards are expectations that Registered Nurses provide support and professional development to undergraduate nursing students undertaking clinical placements. Expectations within nursing standards that Registered Nurses provide support and professional development to nursing students are important because nursing students depend on Registered Nurses to help them to become competent practitioners. Contributing factors that enable and deter Registered Nurses from fulfilling this expectation to support nursing students in their clinical learning include; workloads, preparedness for the teaching role, confidence in teaching and awareness of the competency requirement to support students. Factors exist which can enable or deter Registered Nurses from carrying out the licence requirement to provide clinical education and support to nursing students.

    This column explores how peer support provider training is enhanced through collaborative learning. Collaborative learning is an approach that draws upon the "real life" experiences of individual learners and encompasses opportunities to explore varying perspectives and collectively construct solutions that enrich the practice of all participants. This description draws upon published articles and examples of collaborative learning in training and communities of practice of peer support providers. Similar to person-centered practices that enhance the recovery experience of individuals receiving services, collaborative learning enhances the experience of peer support providers as they explore relevant "real world" issues, offer unique contributions, and work together toward improving practice. Three examples of collaborative learning approaches are provided that have resulted in successful collaborative learning opportunities for peer support providers.

  10. What do cancer support groups provide which other supportive relationships do not? The experience of peer support groups for people with cancer.

    Science.gov (United States)

    Ussher, Jane; Kirsten, Laura; Butow, Phyllis; Sandoval, Mirjana

    2006-05-01

    This qualitative study examined the questions of what cancer support groups provide that other supportive relationships do not, and what the self perceived consequences are of support group attendance. Nine representative Australian cancer peer support groups, consisting of a total of 93 interviewees, 75 women, and 18 men, with a mean age of 62, took part in participant observation and focus group interviews, with the data analysed using positioning theory. Support groups were positioned by participants as providing a unique sense of community, unconditional acceptance, and information about cancer and its treatment, in contrast to the isolation, rejection, and lack of knowledge about cancer frequently experienced outside the group. Groups were also positioned as occasionally emotionally challenging, in contrast to the experience of normalising support from family and friends. Increased empowerment and agency were positioned as the most significant consequences of group support, consisting of increased confidence and a sense of control in relation to self, living with cancer, and interactions with others, in particular the medical profession. The support group was also positioned as facilitating positive relationships with family and friends because of relieving their burden of care, by providing a safe space for the expression of emotion. No difference was found between professionally led and peer led support groups, suggesting that it is not the professional background of the leader which is of importance, but whether the group provides a supportive environment, mutuality, and a sense of belonging, and whether it meets the perceived needs of those attending. It is suggested that future research should examine the construction and experience of social support in those who drop out of, or who do not attend, cancer support groups, in order to provide further insight into the contrast between social support within groups and support in other contexts.

  12. Support Needs for Canadian Health Providers Responding to Disaster: New Insights from a Grounded Theory Approach.

    Science.gov (United States)

    Fahim, Christine; O'Sullivan, Tracey L; Lane, Dan

    2015-07-01

    An earlier descriptive study exploring the various supports available to Canadian health and social service providers who deployed to the 2010 earthquake disaster in Haiti, indicated that when systems are compromised, professionals are at physical, emotional and mental risk during overseas deployment. While these risks are generally well-identified, there is little literature that explores the effectiveness of the supports in place to mitigate this risk. This study provides evidence to inform policy development regarding future disaster relief, and the effectiveness of supports available to responders assisting with international disaster response. This study follows Strauss and Corbin's 1990 structured approach to grounded theory to develop a framework for effective disaster support systems. N=21 interviews with Canadian health and social service providers, who deployed to Haiti in response to the 2010 earthquake, were conducted and analyzed. Resulting data were transcribed, coded and analysed for emergent themes. Three themes were identified in the data and were used to develop the evolving theory. The interview data indicate that the experiences of responders are determined based on an interaction between the individual's 'lens' or personal expectations, as well as the supports that an organization is able to provide. Therefore, organizations should consider the following factors: experience, expectations, and supports, to tailor a successful support initiative that caters to the needs of the volunteer workforce.

  13. Support Operators Method for the Diffusion Equation in Multiple Materials

    Energy Technology Data Exchange (ETDEWEB)

    Winters, Andrew R. [Los Alamos National Laboratory; Shashkov, Mikhail J. [Los Alamos National Laboratory

    2012-08-14

    A second-order finite difference scheme for the solution of the diffusion equation on non-uniform meshes is implemented. The method allows the heat conductivity to be discontinuous. The algorithm is formulated on a one dimensional mesh and is derived using the support operators method. A key component of the derivation is that the discrete analog of the flux operator is constructed to be the negative adjoint of the discrete divergence, in an inner product that is a discrete analog of the continuum inner product. The resultant discrete operators in the fully discretized diffusion equation are symmetric and positive definite. The algorithm is generalized to operate on meshes with cells which have mixed material properties. A mechanism to recover intermediate temperature values in mixed cells using a limited linear reconstruction is introduced. The implementation of the algorithm is verified and the linear reconstruction mechanism is compared to previous results for obtaining new material temperatures.

    Full Text Available For families that are not capable to obtain necessary supplies to meet their needs, State’s social policy guidelines determine support for improving the quality of life for these families. However, it is concluded, that neither the state nor municipality’ provided support for families with children with special needs, does not meet the needs of families, because state social policy is not focused on the assessment of the family needs, as well as often families do not receive the support due to lack of necessary information and disinterest by social service workers, which in turn reflects the problems in social policy delivery mechanisms. The most necessary support that families need is concerned with lodging and financial security, lack of assistants/care at home, as well as – emotional support.

  17. Macintosh support is provided at the level of the Service Desk

    CERN Multimedia

    2011-01-01

    Since September 2010 the Apple laptops & desktops with Mac OS are recognized and supported at CERN by the IT department. Therefore, the “Macintosh support” procedure now follows the same ITIL*) schema as for all IT services, i.e.: All CERN users must address any request for support on Macintosh PCs to the Service Desk. The Service Desk will move on questions or problems they cannot solve to “IT 2nd level” support people, provided by the “computing support” contract managed by IT department. Mac OS being officially supported by the IT department, a 3rd level support is provided by CERN IT staff; they may give specialized expert assistance, within the scope described at the ITUM-2 presentation, for all incidents or requests which can be neither resolved nor fulfilled by the Service Desk (1st level) and the 2nd level support people. Therefore, users who have problems related to Mac OS should simply fill-in the appropriate form from th...

    Objective To explore patients’ and nurses’ views on the feasibility and acceptability of providing psychological care within cardiac rehabilitation services. Design In-depth interviews analysed thematically. Participants 18 patients and 7 cardiac nurses taking part in a pilot trial (CADENCE) of an enhanced psychological care intervention delivered within cardiac rehabilitation programmes by nurses to patients with symptoms of depression. Setting Cardiac services based in the South West of England and the East Midlands, UK. Results Patients and nurses viewed psychological support as central to good cardiac rehabilitation. Patients’ accounts highlighted the significant and immediate adverse effect a cardiac event can have on an individual’s mental well-being. They also showed that patients valued nurses attending to both their mental and physical health, and felt this was essential to their overall recovery. Nurses were committed to providing psychological support, believed it benefited patients, and advocated for this support to be delivered within cardiac rehabilitation programmes rather than within a parallel healthcare service. However, nurses were time-constrained and found it challenging to provide psychological care within their existing workloads. Conclusions Both patients and nurses highly value psychological support being delivered within cardiac rehabilitation programmes but resource constraints raise barriers to implementation. Consideration, therefore, should be given to alternative forms of delivery which do not rely solely on nurses to enable patients to receive psychological support during cardiac rehabilitation.

    Managing and administering medications to relieve pain and symptoms are common, important responsibilities for informal caregivers of patients receiving end-of-life care at home. However, little is known about how hospice providers prepare and support caregivers with medication-related tasks. This qualitative study explores the key approaches that hospice providers use to facilitate medication management for caregivers. Semistructured, open-ended interviews were conducted with 22 providers (14 nurses, four physicians, and four social workers) from four hospice organizations around an urban setting in the midwestern U.S. Based on the interviews, the following five key approaches emerged, constituting how the hospice team collectively helped caregivers manage medications: 1) establishing trust; 2) providing information; 3) promoting self-confidence; 4) offering relief (e.g., provided in-home medication assistance, mobilized supportive resources, and simplified prescriptions); and 5) assessing understanding and performance. Each hospice discipline used multiple approaches. Nurses emphasized tailoring information to individual caregivers and patients, providing in-home assistance to help relieve caregivers, and assessing caregivers' understanding and performance of medication management during home visits. Physicians simplified medication prescriptions to alleviate burden and reassured caregivers using their perceived medical authority. Social workers facilitated medication management by providing emotional support to promote self-confidence and mobilizing resources in caregivers' support networks and the community at large. Hospice nurses, physicians, and social workers identified distinct, yet overlapping, approaches in aiding caregivers with medication management. These findings emphasize the importance of interdisciplinary teamwork among hospice providers. Future research should investigate how common, standardized, effective, and efficient these approaches are in

    2015-06-01

    This study is based on people dying at home relying on the care of unpaid family carers. There is growing recognition of the central role that family carers play and the burdens that they bear, but knowledge gaps remain around how to best support them. The aim of this study is to review the literature relating to the perspectives of family carers providing support to a person dying at home. A narrative literature review was chosen to provide an overview and synthesis of findings. The following search terms were used: caregiver, carer, 'terminal care', 'supportive care', 'end of life care', 'palliative care', 'domiciliary care' AND home AND death OR dying. During April-May 2013, Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PsycINFO, Pubmed, Cochrane Reviews and Citation Indexes were searched. Inclusion criteria were as follows: English language, empirical studies and literature reviews, adult carers, perspectives of family carers, articles focusing on family carers providing end-of-life care in the home and those published between 2000 and 2013. A total of 28 studies were included. The overarching themes were family carers' views on the impact of the home as a setting for end-of-life care, support that made a home death possible, family carer's views on deficits and gaps in support and transformations to the social and emotional space of the home. Many studies focus on the support needs of people caring for a dying family member at home, but few studies have considered how the home space is affected. Given the increasing tendency for home deaths, greater understanding of the interplay of factors affecting family carers may help improve community services. © The Author(s) 2015.

    2017-08-31

    The aim of this project was to identify the support required by registered nurses and unregistered healthcare support workers to provide palliative care for people with dementia in an acute hospital in England. A quantitative approach was taken and participants were asked to fill in a questionnaire. Data were collated and analysed to identify support needs and any emerging themes. Respondents were confident in identifying the different stages of dementia. There was less confidence in identifying a patient with dementia for palliative care referral compared with a patient without dementia. Further needs were identified by respondents in supporting the family/carer of the person with dementia and being aware of available support to facilitate palliative care for people with dementia and support for end of life care (EoLC) planning. The findings suggest that further work is required in relation to dementia and EoLC. Practical and educational collaboration with EoLC/palliative care practitioners and dementia leads would be beneficial.

    2018-01-01

    Each library has its own criteria and differences in the importance of each criterion in choosing an e-book provider for them. The large number of providers and the different importance levels of each criterion make the problem of determining the e-book provider to be complex and take a considerable time in decision making. The aim of this study was to implement Decision support system (DSS) to assist the library in selecting the best e-book provider based on their preferences. The way of DSS works is by comparing the importance of each criterion and the condition of each alternative decision. SAW is one of DSS method that is quite simple, fast and widely used. This study used 9 criteria and 18 provider to demonstrate how SAW work in this study. With the DSS, then the decision-making time can be shortened and the calculation results can be more accurate than manual calculations.

    2017-12-21

    Mobile health technology is rapidly evolving with the potential to transform health care. Self-management of health facilitated by mobile technology can maximize long-term health trajectories of adults. Little is known about the characteristics of adults seeking Web-based support from health care providers facilitated by mobile technology. This study aimed to examine the following: (1) the characteristics of adults who seek human support from health care providers for health concerns using mobile technology rather than from family members and friends or others with similar health conditions and (2) the use of mobile health technology among adults with chronic health conditions. Findings of this study were interpreted in the context of the Efficiency Model of Support. We first described characteristics of adults seeking Web-based support from health care providers. Using chi-square tests for categorical variables and t test for the continuous variable of age, we compared adults seeking Web-based and conventional support by demographics. The primary aim was analyzed using multivariate logistic regression to examine whether chronic health conditions and demographic factors (eg, sex, income, employment status, race, ethnicity, education, and age) were associated with seeking Web-based support from health care providers. The sample included adults (N=1453), the majority of whom were female 57.60% (837/1453), white 75.02% (1090/1453), and non-Hispanic 89.13% (1295/1453). The age of the participants ranged from 18 to 92 years (mean 48.6, standard deviation [SD] 16.8). The majority 76.05% (1105/1453) of participants reported college or higher level of education. A disparity was found in access to health care providers via mobile technology based on socioeconomic status. Adults with annual income of US $30,000 to US $100,000 were 1.72 times more likely to use Web-based methods to contact a health care provider, and adults with an annual income above US $100,000 were 2.41 to

  8. Biotemplated Palladium Catalysts Can Be Stabilized on Different Support Materials

    © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Sustainably biotemplated palladium catalysts generated on different carbon-based support materials are examined for durability under electrochemical (oxidative) and mechanical-stress conditions. Biotemplated catalysts on carbon paper under both stresses retain 95% (at 0.6V) of the initial catalytic activity as opposed to 70% for carbon cloth and 60% for graphite. Graphite electrodes retain 95% of initial catalytic activity under a single stress. Using electrodeposited polyaniline (PANI) and polydimethylsiloxane binder increases the current density after the stress tests by 22%, as opposed to a 30% decrease for Nafion. PANI-coated electrodes retain more activity than carbon-paper electrodes under elevated mechanical (94 versus 70%) or increased oxidative (175 versus 62%) stress. Biotemplated catalytic electrodes may be useful alternatives to synthetically produce catalysts for some electrochemical applications. Sustainable electrode fabrication: The biotemplated synthesis of catalytic porous electrodes is a sustainable process and, according to the results of durability tests under electrochemical and mechanical stress, these electrodes (e.g. the Pd/carbon paper electrode shown in the picture) are durable enough to replace catalytic electrodes based on synthetic materials in certain applications.

    PurposeExpanded carrier screening (ECS) for a large number of recessive disorders is available to prospective parents through commercial providers. This study aimed to analyze the content of marketing materials on ECS providers' websites.MethodsTo identify providers of ECS tests, we undertook a comprehensive online search, reviewed recent academic literature on commercial carrier screening, and consulted with colleagues familiar with the current ECS landscape. The identified websites were archived in April 2017, and inductive content analysis was performed on website text, brochures and educational materials, and video transcripts.ResultsWe identified 18 ECS providers, including 16 commercial genetic testing companies. Providers typically described ECS as an important family planning tool. The content differed in both the tone used to promote ECS and the accuracy and completeness of the test information provided. We found that most providers offered complimentary genetic counseling to their consumers, although this was often optional, limited to the posttest context, and, in some cases, appeared to be available only to test-positive individuals.ConclusionThe quality of ECS providers' websites could be improved by offering more complete and accurate information about ECS and their tests. Providers should also ensure that all carrier couples receive posttest genetic counseling to inform their subsequent reproductive decision making.Genet Med advance online publication, 14 December 2017; doi:10.1038/gim.2017.222.

    Research demonstrates considerable inequalities in service delivery and health outcomes for people with cancer living outside large metropolitan cities. Semi-structured interviews with 11 professionals providing grief and loss support for people with cancer and their families in rural, regional, and remote areas Western Australia revealed the challenges they faced in delivering such support. The data are presented in four themes - Inequity of regional versus metropolitan services, Strain of the 'Jack of all trades' role, Constraints to accessing professional development, and Challenges in delivering post-bereavement services. These challenges are likely to be of growing concern given that populations are declining in rural areas as Australia becomes increasingly urban. The findings have implications in enhancing the loss and grief support services available in rural, regional, and remote Western Australia, including those grieving the death of a loved one through cancer. © 2013 John Wiley & Sons Ltd.

    2017-06-01

    The compact, multipurpose electrostatic tandem accelerators are extensively used for production of ion beams with energies in the range from 400 keV to 24 MeV of almost all elements of the periodic system for the trace element analysis by means of nuclear analytical methods. The ion beams produced by small accelerators have a broad application, mainly for material characterization (Rutherford Back-Scattering spectrometry, Particle Induced X ray Emission analysis, Nuclear Reaction Analysis and Ion-Microprobe with 1 μm lateral resolution among others) and for high-energy implantation. Material research belongs to traditionally progressive fields of technology. Due to the continuous miniaturization, the underlying structures are far beyond the analytical limits of the most conventional methods. Ion Beam Analysis (IBA) techniques provide this possibility as they use probes of similar or much smaller dimensions (particles, radiation). Ion beams can be used for the synthesis of new progressive functional nanomaterials for optics, electronics and other applications. Ion beams are extensively used in studies of the fundamental energetic ion interaction with matter as well as in the novel nanostructure synthesis using ion beam irradiation in various amorphous and crystalline materials in order to get structures with extraordinary functional properties. IBA methods serve for investigation of materials coming from material research, industry, micro- and nano-technology, electronics, optics and laser technology, chemical, biological and environmental investigation in general. Main research directions in laboratories employing small accelerators are also the preparation and characterization of micro- and nano-structured materials which are of interest for basic and oriented research in material science, and various studies of biological, geological, environmental and cultural heritage artefacts are provided too.

    2014-02-01

    Health professionals are vulnerable to occupational stress and tend to report high levels of secondary trauma and burnout; this is especially so for those working in "high-death" contexts such as cancer support and palliative care. In this study, 38 health professionals (psychologists, social workers, pastoral carers/chaplains, nurses, group facilitators, and a medical practitioner) who provide grief support and counseling in cancer and palliative care each participated in a semistructured interview. Qualitatively, a grounded theory analysis revealed four themes: (a) the role of health professionals in supporting people who are experiencing grief and loss issues in the context of cancer, (b) ways of working with patients with cancer and their families, (c) the unique qualities of cancer-related loss and grief experiences, and (d) the emotional demands of the work and associated self-care. The provision of psychological services in the context of cancer is colored by the specter of cancer, an unseen yet real phenomenon that contributes to secondary trauma and burnout. The participants' reported secondary trauma has serious repercussions for their well-being and may compromise the care they provide. The findings have implications for the retention and well-being of personnel who provide psychosocial care in cancer and the quality and delivery of services for people with cancer and their families.

    The first Ebola cases in West Africa were reported by the Guinea Ministry of Health on March 23, 2014, and by June it became the largest recorded Ebola outbreak. Centers for Disease Control and Prevention field teams were deployed to West Africa, including in-country logistics staff who were critical for ensuring the movement of staff, equipment, and supplies to locations where public health knowledge and experience were applied to meet mission-related requirements. The logistics role was critical to creating the support for epidemiologists, medical doctors, laboratory staff, and health communicators involved in health promotion activities to successfully respond to the epidemic, both in the capital cities and in remote villages. Logistics personnel worked to procure equipment, such as portable video projectors, and have health promotion materials printed. Logistics staff also coordinated delivery of communication and health promotion materials to the embassy and provided assistance with distribution to various partners. © 2015 Society for Public Health Education.

    Many pediatric oncology patients undergoing hematopoietic stem cell transplantation (HSCT) require nutritional support (NS) because of their inability to consume adequate caloric intake enough calories orally. Although NS can be provided either enteraly (EN) or parenteraly (PN), EN is the preferred method of NS as long as if the gastrointestinal tract is functioning. In this qualitative study, we determined the type of NS preferences and the reservations of caregivers of pediatric HSCT patients undergoing hematopoietic stem cell transplantation (HSCT) as well as those of health care (HC) providers working on the HSCT unit. A survey was developed and completed anonymously by HC providers and caregivers. The hypothesis was that HC providers and caregivers would prefer PN because it is convenient to use in patients who already have a central line in place. Most caregivers preferred PN to EN, while most HC providers preferred EN to PN. The barrier between EN initiation and caregivers' approval was the caregivers' perception that EN was invasive and painful, most common obstacle for initiation of EN among caregivers was that it hurts/is invasive, while the barrier with HC providers was vomiting and/abdominal pain associated with EN. If caregivers were better educated about NS and the advantages/disadvantages of the different forms of NS, their preferences may change. There have been policy changes at St. Jude have been implemented since this study, and an outpatient dietitian now provides education to caregivers about NS during the pre-evaluation for HSCT. © 2015 Wiley Periodicals, Inc.

    2016-01-01

    Full Text Available Over the last decade the UK’s joint Flood and Coastal Erosion Risk Management Research and Development programme has been developing methods to support a move to a risk-based approach to flood defence asset management. Looking to ensure investment is less ‘find and fix’ and made to those assets where the biggest risk reduction can be made for the money available. In addition, providing the capability to articulate the benefits of investing in these assets quantitatively and transparently. This paper describes how the Asset Performance Tools (APT project [1] is delivering practical methods, prototype tools and supporting guidance which, together with related initiatives such as the Environment Agency’s Creating Asset Management Capacity (CAMC strategic programme [2] and the ‘State of the Nation’ (SoN [3] supportive datasets, will enable a risk-based, ‘predict and protect’ approach to asset management. A key advance is the ability to bring in local knowledge to make national generic datasets locally relevant. The paper also highlights existing outputs that can already be used to support a more proactive approach to asset management. It will summarise the ongoing work which will further develop and fine tune performance assessment and investment decision processes within an integrated conceptual framework aligned with ISO55000, deliverable via CAMC and whose concepts can be used by all risk management authorities.

    The Veterans Health Administration (VHA) has implemented MOVE!, a weight-management program for veterans designed to address the increasing proportion of overweight and obese veterans. The objective of our study was to determine whether peer support employing motivational interviewing (MI) could positively influence lifestyle changes, thus expanding the reach of the MOVE! program. We describe the initial evaluation of the peer training program. We developed an MI peer ounselor training program for volunteer veterans, the "Buddies" program, to provide one-on-one telephone support for veterans enrolled in MOVE!. Buddies were recruited at 5 VHA sites and trained to provide peer support for the 6-month MOVE! intervention. We used a DVD to teach MI skills and followed with 2 to 3 booster sessions. We observed training, conducted pre- and posttraining surveys, and debriefed focus groups to assess training feasibility. Fifty-six Buddies were trained. Results indicate positive receipt of the program (89% reported learning about peer counseling and 87% reported learning communication skills). Buddies showed a small improvement in MI self-efficacy on posttraining surveys. We also identified key challenges to learning MI and training implementation. MI training is feasible to implement and acceptable to volunteer Buddies. Trainers must assess how effectively volunteers learn MI skills in order to enhance its effective use in health promotion.

    The Oncology Family App supports families across the vast state of Queensland, Australia, with easy access to vital information, including management plans for a deteriorating child, patient specific information and other resources. This article describes the development and evaluation of this mobile app. The app was developed and tested in collaboration with parents, caregivers, and clinicians and released in November 2015. This first version featured "Statewide Hospital Contacts," including phone numbers, links to Google maps, and 24-hour emergency contacts with click to call functionality; "When to Call" describing symptoms to look out for in a deteriorating child; "Blood Results Table"; and "Information" listing recommended websites, health care team contacts, appointments, and notes. The app was evaluated through interviews with parents, caregivers and patients and download metrics. Six months after the app release, 68% of the 38 parents and caregivers surveyed had downloaded the app. The most used modules were "Blood Results Table," "When to Call," and "Statewide Hospital Contacts," but families reported using all features available. Families were enthusiastic about the support the app provided and gave useful feedback to direct future development. Using mobile health technology to support families is a novel, but rapidly growing concept. Family and caregiver feedback showed that the Oncology Family App was an efficient and convenient way to provide much needed information. A new version of the app is under development and evaluation of outcomes will be ongoing.

    Volunteer computing has the potential to provide significant additional computing capacity for the LHC experiments. One of the challenges with exploiting volunteer computing is to support a global community of volunteers that provides heterogeneous resources. However, high energy physics applications require more data input and output than the CPU intensive applications that are typically used by other volunteer computing projects. While the so-called databridge has already been successfully proposed as a method to span the untrusted and trusted domains of volunteer computing and Grid computing respective, globally transferring data between potentially poor-performing residential networks and CERN could be unreliable, leading to wasted resources usage. The expectation is that by placing a storage endpoint that is part of a wider, flexible geographical databridge deployment closer to the volunteers, the transfer success rate and the overall performance can be improved. This contribution investigates the provision of a globally distributed databridge implemented upon a commercial cloud provider.

    2009-09-01

    Because of the high costs associated with new graduate nurse turnover, an academic-service partnership developed a nurse residency program that provides a comprehensive support system that spans 15 months. Now in its fourth year, involving more than 50 urban and rural hospitals of varying sizes and geographic locations, the program provides formalized preceptor training, monthly daylong educational sessions, and mentoring by clinical coaches. Key factors contributing to the success of this program are a dedicated, cohesive planning team of individuals who embrace a common agenda, stakeholder buy-in, appropriate allocation of resources, and clear articulation of measures of success, with associated data collection. Successful elements of the monthly educational sessions are the use of interactive teaching methods, inclusion of content tailored to the unique needs of the nurse residents, and storytelling to facilitate learning from practice. Finally, training to advance the skill development of preceptors, coaches, educators, and facilitators has provided organizations with enduring benefits. Copyright 2009, SLACK Incorporated.

    Tobacco use during pregnancy is substantially higher among Aboriginal women compared to non-Aboriginal women in Australia. However, no studies have investigated the amount or type of smoking cessation care that staff from Aboriginal antenatal and postnatal services provide to clients who smoke or staff confidence to do so. This study examined Aboriginal antenatal and postnatal staff confidence, perceived role and delivery of smoking cessation care to Aboriginal women and characteristics associated with provision of such care. Staff from 11 Aboriginal Maternal and Infant Health Services and eight Aboriginal Child and Family Health services in the Hunter New England Local Health District in Australia completed a cross-sectional self-reported survey (n = 67, response rate = 97.1%). Most staff reported they assessed clients' smoking status most or all of the time (92.2%). However, only a minority reported they offered a quitline referral (42.2%), provided follow-up support (28.6%) or provided nicotine replacement therapy (4.7%) to most or all clients who smoked. Few staff felt confident in motivating clients to quit smoking (19.7%) and advising clients about using nicotine replacement therapy (15.6%). Staff confident with talking to clients about how smoking affected their health had significantly higher odds of offering a quitline referral [OR = 4.9 (1.7-14.5)] and quitting assistance [OR = 3.9 (1.3-11.6)] to clients who smoke. Antenatal and postnatal staff delivery of smoking cessation care to pregnant Aboriginal women or mothers with young Aboriginal children could be improved. Programs that support Aboriginal antenatal and postnatal providers to deliver smoking cessation care to clients are needed. Aboriginal antenatal and postnatal service staff have multiple opportunities to assist Aboriginal women to quit smoking during pregnancy and postpartum. However, staff confidence and practices of offering various forms of smoking cessation support to pregnant Aboriginal

    The purpose of the study examined in this article was to understand how non-physician health care professionals working in Canadian primary health care settings facilitate older persons' access to community support services (CSSs). The use of CSSs has positive impacts for clients, yet they are underused from lack of awareness. Using a qualitative description approach, we interviewed 20 health care professionals from various disciplines and primary health care models about the processes they use to link older patients to CSSs. Participants collaborated extensively with interprofessional colleagues within and outside their organizations to find relevant CSSs. They actively engaged patients and families in making these linkages and ensured follow-up. It was troubling to find that they relied on out-of-date resources and inefficient search strategies to find CSSs. Our findings can be used to develop resources and approaches to better support primary health care providers in linking older adults to relevant CSSs.

    Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015. Grantees recruited participants and held educational sessions using Inside Knowledge materials. Questionnaires were given before and after the sessions to assess changes in awareness, confidence, and behavioral intentions around gynecologic cancer information and analyzed in 2016. This analysis focused on an assessment of changes related to ovarian cancer information. Participants' knowledge increased after educational sessions. Among women, there were increases in correctly identifying that the Papanicolaou (Pap) test does not screen for ovarian cancer (89.2%) and that genetic testing is available (77.9%). There was a lower increase in knowledge that HPV is not a cause of ovarian cancer (56.4%). Providers and women reported significant increases in their confidence in their ability to talk to each other about gynecologic cancer post-session. Ovarian cancer awareness, confidence, and related behaviors increased in participants exposed to Inside Knowledge materials. Using these materials to increase knowledge could lead to more empowered patients, better provider-patient communications, and improved care for gynecologic cancers, including ovarian cancer.

    2007-05-01

    Full Text Available Abstract Background Clinical interventions based on collaborative models require effective communication between primary care providers (PCPs and collaborative support teams. Despite growing interest in collaborative care, we have identified no published studies describing how PCPs prefer to communicate and interact with collaborative support teams. This manuscript examines the communication and interaction preferences of PCPs participating in an ongoing randomized clinical trial of a collaborative intervention for chronic pain and depression. Methods The trial is being conducted in five primary care clinics of a Veterans Affairs Medical Center. Twenty-one PCPs randomized to the study intervention completed a survey regarding preferences for interacting with the collaborative support team. Results A majority of PCPs identified email (95% and telephone calls (68% as preferred modes for communicating with members of the support team. In contrast, only 29% identified in-person communications as preferred. Most PCPs preferred that the care manager and physician pain specialist assess patients (76% and make initial treatment changes (71% without first conferring with the PCP. One-half wanted to be designated cosigners of all support team notes in the electronic medical record, one-half wanted to receive brief and focused information rather than in-depth information about their patients, and one-half wanted their practice nurses automatically included in communications. Panel size was strongly associated (p Conclusion The substantial variation in PCP communication preferences suggests the need for knowledge of these preferences when designing and implementing collaborative interventions. Additional research is needed to understand relationships between clinician and practice characteristics and interaction preferences.

    The purpose of this analysis report is to evaluate and document the inclusion or exclusion of the disruptive events features, events, and processes (FEPs) with respect to modeling used to support the total system performance assessment for license application (TSPA-LA). A screening decision, either ''Included'' or ''Excluded,'' is given for each FEP, along with the technical basis for screening decisions. This information is required by the U.S. Nuclear Regulatory Commission (NRC) at 10 CFR 63.114 (d), (e), and (f) [DIRS 156605]. The FEPs addressed in this report deal with both seismic and igneous disruptive events, such as fault displacements through the repository and an igneous intrusion into the repository. For included FEPs, this analysis summarizes the implementation of the FEP in TSPA-LA (i.e., how the FEP is included). For excluded FEPs, this analysis provides the technical basis for exclusion from TSPA-LA (i.e., why the FEP is excluded). Previous versions of this report were developed to support the total system performance assessments (TSPA) for various prior repository designs. This revision addresses the repository design for the license application (LA).

    The objective of this study is to develop, implement, and evaluate a training program for healthcare providers to improve ability to provide psychosocial support to breast cancer survivors in Korea. Based on a needs assessment survey and in-depth interviews with breast cancer survivors, a multidisciplinary team developed two-day intensive training program as well as education materials and counseling notes. Participants' overall satisfaction was evaluated after the training. The training program included a total of 16 lectures held over the course of seven sessions. Forty-one nurses and 3 social workers participated in the training program. Mean age was 37.5(± 6.4) years, and on average, they had 11.1 (± 5.6) years of experience. Participants' overall satisfaction was good as following: program contents (4.04), trainee guidebook (3.82), location and environment (4.10), and program organization (4.19). Among the participants, 31 (70.4%) received certification after submitting real consultation cases after the training. Two day intensive training can provide a comprehensive and coordinated education to healthcare professionals for implementing survivorship care with an emphasis on psychosocial support. Furthermore, the program should resume as a periodic continuing education course for healthcare providers. Similar education for graduate students in oncology nursing would be beneficial.

    This study reports a material that is based on the concept of ionic liquid analogue: a slightly crosslinked polymer-supported imidazolium trifluoroacetate salt (IL-CF(3)COO(-)) that favorably combines the properties of ionic liquids (ILs) and the advantages of a solid support. The ionic liquid-supported material was evaluated for the first time as a solid-phase extraction (SPE) sorbent for selectively and quantitatively extracting pharmaceuticals from aqueous samples. The novel IL-CF(3)COO(-) was evaluated under reversed-phase (RP), weak anion exchange (WAX), strong anion exchange (SAX) and strong cation exchange (SCX) SPE procedures, and we found that SAX conditions are the most suitable for investigating the behaviour of the IL-CF(3)COO(-) material. Under SAX conditions, the IL-CF(3)COO(-) material was capable of selectively and quantitatively extracting a group of acidic compounds from aqueous samples, while washing basic analytes that were also present in the sample. The SPE method using IL-CF(3)COO(-) material was used to analyse 1000 ml of different aqueous samples (ultrapure, tap and river) with complete recovery of the acidic compounds studied. Moreover, the method provided clean chromatogram and high recoveries when percolating complex real samples, such as 1000 ml of river water and 250 ml of effluent wastewater from a sewage treatment plant spiked at low levels with the analytes studied.

    Callicoat, Jeffrey R.

    With the proliferation of Unmanned Aerial Vehicles (UAVs) in civilian airspace in the near future, community noise will be a major issue of concern. Numerous studies have shown a direct link between community noise pollution (i.e., road traffic noise and airport noise) and serious health problems. There exists, therefore, a pressing need to create quiet UAVs, and this drives the need for noise-attenuating materials and structures suitable for UAV airframe fabrication. By shrouding predominant noise sources such as the engine, exhaust, and even the propeller (in the case of a ducted fan) with the airframe structure, the airframe can serve as a noise transmission barrier and substantially reduce UAV noise profiles. The present research effort is an experimental investigation of light-weight fiber-reinforced composite materials to provide high acoustic transmission loss (TL) for use in fabricating UAV airframes. A transmission loss tube acoustic test system was designed, fabricated, and validated, and extensive testing was done on numerous composite layups of interest for UAV fabrication. Composites under study included carbon fiber, fiberglass, and Kevlar fabrics as skin materials along with vinyl foam, Nomex honeycomb, and balsawood as core materials. Results from testing small 3"x3" samples in the TL tube led to the selection of four composite sandwich panels of interest for further study. Larger 36"x36" test samples of these selected layups were then fabricated and tested using a 2-room methodology. Whereas the TL tube yielded results in the stiffness-controlled region of acoustic behavior, the 2-room tests produced results in the mass-controlled region for these materials, enabling relative performance comparisons over both acoustic regimes. Recognizing that a good material for airframe fabrication should possess not only high TL, but also low weight and high stiffness, load-deflection tests were conducted and overall material performance was compared in terms of

    A lack of curriculum time devoted to teaching dental students about the needs of lesbian, gay, bisexual, and transgendered (LGBT) health care patient needs and biases against LGBT students and faculty have been reported. Understanding dental school administrators' attitudes about LGBT students' needs might provide further insight into these long-standing issues. The aims of this study were to develop a survey to assess dental administrators' attitudes regarding the support services they believe LGBT-identified students need, to identify dental schools' current diversity inclusion policies, and to determine what types of support dental schools currently provide to LGBT students. A survey developed with the aid of a focus group, cognitive interviewing, and pilot testing was sent to 136 assistant and associate deans and deans of the 65 U.S. and Canadian dental schools. A total of 54 responses from 43 (66%) schools were received from 13 deans, 29 associate deans, and 11 assistant deans (one participant did not report a position), for a 40% response rate. The findings suggest there is a considerable lack of knowledge or acknowledgment of LGBT dental students' needs. Future studies are needed to show the importance of creating awareness about meeting the needs of all dental student groups, perhaps through awareness campaigns initiated by LGBT students.

To evaluate the efficiency of the BLS training program provided for nurses in a university hospital. Methods: In this a quasi-experimental study, a total of 404 nurses who received BLS training were enrolled. The study was performed in two stages. In stage one, the participant nurses were given a pre-test that consisted of 25 questions, four points each, before the training on the first day of the 2-day BLS training. The post-test was conducted in addition to practical exams on manikins to determine nurses’ practice skills on BLS. Results: There was a statistically significant difference between the nurses with previous BLS training and the difference between their pre- and post-test results (p<0.05, and high statistically significant difference was found between the nurses with previous advanced life support (ALS training and the difference between their pre- and post-test results (p<0.001. Conclusion: Nurses should receive BLS training in hospitals and the training should be repeated on a regular basis. The BLS training that the nurses received in this study was effective and increased their knowledge level on BLS

    We examined the effects of participating in a "train-the-trainer" program and being a peer supporter on metabolic and cognitive/psychological/behavioral parameters in Chinese patients with type 2 diabetes. In response to our invitation, 79 patients with fair glycemic control (HbA1c peer supporters. Of the 59 who completed the program successfully, 33 agreed to be peer supporters ("agreed trainees") and were each assigned to support 10 patients for 1 year, with a voluntary extension period of 3 additional years, while 26 trainees declined to be supporters ("refused trainees"). A group of 60 patients with fair glycemic control who did not attend the training program and were under usual care were selected as a comparison group. The primary outcome was the change in average HbA1c levels for the 3 groups from baseline to 6 months. At 6 months, HbA1c was unchanged in the trainees (at baseline, 7.1 ± 0.3%; at 6 months, 7.1 ± 1.1%) but increased in the comparison group (at baseline, 7.1 ± 0.5%; at 6 months, 7.3 ± 1.1%. P = .02 for between-group comparison). Self-reported self-care activities including diet adherence and foot care improved in the trainees but not the comparison group. After 4 years, HbA1c remained stable among the agreed trainees (at baseline, 7.0 ± 0.2%; at 4 years: 7.2 ± 0.6%), compared with increases in the refused trainees (at baseline, 7.1 ± 0.4%; at 4 years, 7.8 ± 0.8%) and comparison group (at baseline, 7.1 ± 0.5%; at 4 years, 8.1 ± 0.6%.

    Full Text Available Background There is a consensus among the halachic authorities that life-saving actions override Sabbath prohibitions. They are painstaking in securing that the sanctity of the Sabbath is maintained but that not a single life be lost. Objective This manuscript examines if and when a relative’s presence at the bedside of a seriously ill individual is potentially life-saving against the backdrop of the scientific literature. It specifically addresses the permissibility of traveling in a motorized vehicle, generally prohibited on the Sabbath, to be with one’s relative in hospital for the provision of emotional support. Methods Discourse of the halachic issues in the context of the scientific literature. Results Stress, mental or physical, has been determined as a potentially life-threatening condition in many disease entities. The literature attests to both the patient’s and the professionals’ perception of the curative potential of the presence of loved ones by advocating for the patient and relieving stress in the hospital experience. Emotional support from a loved one is perceived by some patients as vital to survival. There is halachic consensus that a patient’s perception of the emotional need for a relative’s presence is sufficient to permit overriding rabbinic prohibitions. Torah prohibitions, which may be overridden for medical needs, may be overridden for emotional support, providing a health professional or family member attests to the fulfilment of this specific need as diminishing the danger to the patient’s life. In certain cases, the latter contingency is unnecessary. Conclusions Emotional support has an impact on the patient’s health status; the degree to which its impact is strong enough to save life is still being studied. As more data from scientific studies emerge, they may be relevant to sharpening the halachic rulings with respect to the issue at hand.

  20. Lipid-anchored Synaptobrevin Provides Little or No Support for Exocytosis or Liposome Fusion.

    SNARE proteins catalyze many forms of biological membrane fusion, including Ca(2+)-triggered exocytosis. Although fusion mediated by SNAREs generally involves proteins anchored to each fusing membrane by a transmembrane domain (TMD), the role of TMDs remains unclear, and previous studies diverge on whether SNAREs can drive fusion without a TMD. This issue is important because it relates to the question of the structure and composition of the initial fusion pore, as well as the question of whether SNAREs mediate fusion solely by creating close proximity between two membranes versus a more active role in transmitting force to the membrane to deform and reorganize lipid bilayer structure. To test the role of membrane attachment, we generated four variants of the synaptic v-SNARE synaptobrevin-2 (syb2) anchored to the membrane by lipid instead of protein. These constructs were tested for functional efficacy in three different systems as follows: Ca(2+)-triggered dense core vesicle exocytosis, spontaneous synaptic vesicle exocytosis, and Ca(2+)-synaptotagmin-enhanced SNARE-mediated liposome fusion. Lipid-anchoring motifs harboring one or two lipid acylation sites completely failed to support fusion in any of these assays. Only the lipid-anchoring motif from cysteine string protein-α, which harbors many lipid acylation sites, provided support for fusion but at levels well below that achieved with wild type syb2. Thus, lipid-anchored syb2 provides little or no support for exocytosis, and anchoring syb2 to a membrane by a TMD greatly improves its function. The low activity seen with syb2-cysteine string protein-α may reflect a slower alternative mode of SNARE-mediated membrane fusion. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    Chronic diseases, such as chronic kidney disease (CKD), are growing in incidence and prevalence, in part due to an aging population. Support provided through home care services may be useful in attaining a more efficient and higher quality care for CKD patients. A systematic review was performed to identify studies examining home care interventions among adult CKD patients incorporating all outcomes. Studies examining home care services as an alternative to acute, post-acute or hospice care and those for long-term maintenance in patients' homes were included. Studies with only a home training intervention and those without an applied research component were excluded. Seventeen studies (10 cohort, 4 non-comparative, 2 cross-sectional, 1 randomized) examined the support provided by home care services in 15,058 CKD patients. Fourteen studies included peritoneal dialysis (PD), two incorporated hemodialysis (HD) and one included both PD and HD patients in their treatment groups. Sixteen studies focused on the dialysis phase of care in their study samples and one study included information from both the dialysis and pre-dialysis phases of care. Study settings included nine single hospital/dialysis centers and three regional/metropolitan areas and five were at the national level. Studies primarily focused on nurse assisted home care patients and mostly examined PD related clinical outcomes. In PD studies with comparators, peritonitis risks and technique survival rates were similar across home care assisted patients and comparators. The risk of mortality, however, was higher for home care assisted PD patients. While most studies adjusted for age and comorbidities, information about multidimensional prognostic indices that take into account physical, psychological, cognitive, functional and social factors among CKD patients was not easily available. Most studies focused on nurse assisted home care patients on dialysis. The majority were single site studies incorporating

    Permanent supportive housing (PSH) is an evidence-based solution to homelessness for persons experiencing chronic or long-term homelessness and one or more physical or behavioral health problems. Health services through PSH typically focus on physical and behavioral health. With the exception of programs specifically designed for persons living with HIV/AIDS, little attention has focused on services through PSH to prevent transmission of HIV or other sexually transmitted infections (STIs), yet sexual risk behavior continues after homeless persons move into PSH. The purpose of this study was to investigate how PSH providers approach HIV prevention and the challenges they perceive surrounding HIV prevention in PSH. Results serve as a critical first step toward addressing the acceptability and feasibility of providing HIV/STI prevention services to PSH residents. As part of a longitudinal mixed methods study examining HIV risk and prevention behavior among homeless unaccompanied adults moving into PSH in Los Angeles, we conducted eleven focus groups with a total of 60 frontline staff across 10 PSH agencies. Thirty-three percent of focus group participants were African American, 32% were Hispanic, and 55% were women. Results suggest that provider awareness and knowledge of PrEP is very limited, and provision of formal HIV prevention programing for residents is perceived as challenging. Informal, ad hoc conversations with residents about sexual risk and HIV prevention do occur when providers have rapport with clients and perceive risk. There are significant gaps in HIV prevention services through PSH but also opportunities to enhance providers' efforts to promote the health of residents through prevention.

    a growing body of literature has highlighted the prevalence of mistreatment that women experience around the globe during childbirth, including verbal and physical abuse, neglect, lack of support, and disrespect. Much of this has been qualitative. Research around the world suggests that support during childbirth can improve health outcomes and behaviours, and improve experiences. Support can be instrumental, informational, or emotional, and can be provided by a variety of people including family (husbands, mothers) or health providers of various professional levels. This study explores women's reported experiences of mistreatment during childbirth quantitatively, and how these varied by specific types of support available and provided by specific individuals. participants were women age 16-30 who had delivered infants in a health facility in the previous five years and were living in slums of Lucknow India. Data were collected on their experiences of mistreatment, the types of support they received, and who provided that support. women who reported lack of support were more likely to report mistreatment. Lack of support in regards to discussions with providers and provider information were most strongly associated with a higher mistreatment score. Women who received any type of support from their husband or a health worker were significantly more likely to report lower mistreatment scores. Receiving informational support from a mother/mother-in-law or emotional support from a health worker was also associated with lower mistreatment scores. However, receiving emotional support from a friend/neighbour/other family member was associated with a higher mistreatment score. women rely on different people to provide different types of support during childbirth in this setting. Some of these individuals provide specific types of support that ultimately improve a woman's overall experience of her childbirth. Interventions aiming to reduce mistreatment to women during

    Airborne field studies are an effective way to gain a detailed understanding of atmospheric processes for scientific research on climate change and air quality relevant issues. One major function of airborne project data management is to maintain seamless data access within the science team. This allows individual instrument principal investigators (PIs) to process and validate their own data, which requires analysis of data sets from other PIs (or instruments). The project's web platform streamlines data ingest, distribution processes, and data format validation. In May 2016, the NASA Langley Research Center (LaRC) Atmospheric Science Data Center (ASDC) developed a new data management capability to help support the Korea U.S.-Air Quality (KORUS-AQ) science team. This effort is aimed at providing direct NASA Distributed Active Archive Center (DAAC) support to an airborne field study. Working closely with the science team, the ASDC developed a scalable architecture that allows investigators to easily upload and distribute their data and documentation within a secure collaborative environment. The user interface leverages modern design elements to intuitively guide the PI through each step of the data management process. In addition, the new framework creates an abstraction layer between how the data files are stored and how the data itself is organized(i.e. grouping files by PI). This approach makes it easy for PIs to simply transfer their data to one directory, while the system itself can automatically group/sort data as needed. Moreover, the platform is "server agnostic" to a certain degree, making deployment and customization more straightforward as hardware needs change. This flexible design will improve development efficiency and can be leveraged for future field campaigns. This presentation will examine the KORUS-AQ data portal as a scalable solution that applies consistent and intuitive usability design practices to support ingest and management of airborne

    Affective symptoms were examined retrospectively in 25 patients following placement of implantable cardioverter defibrillators (ICD) which can produce intermittent shocks without warning in response to cardiac ventricular arrhythmias. The number of ICD random, uncontrollable discharge shocks and pre-ICD history of psychological distress (i.e., depression and/or anxiety) were documented in all patients using a demographics questionnaire and a standardized behavioral/psychological symptoms questionnaire (i.e., Symptom Checklist-90 Revised). ICD patients were dichotomized into two groups: those without a history of psychological distress prior to ICD (n = 18) and those with a history of psychological distress prior to ICD (n = 7). In ICD patients without a prior history, results indicated that quantity of ICD discharge shocks was significantly predictive of current reported depression (r = 0.45, p = 0.03) and current reported anxiety (r = 0.51, p = 0.02). Conversely, in patients with a reported history of psychological distress, there was no significant relationship found between quantity of discharge shocks and current reported depression or anxiety. This study may provide evidence in support of a human model of learned helplessness in that it supports the notion that exposure to an unavoidable and inescapable aversive stimulus was found to be related to patients' reported depression. Further studies may wish to prospectively consider a larger sample as well as a more comprehensive assessment of premorbid psychological symptoms.

    Advanced life support (ALS) guidelines are widely adopted for healthcare provider training with recommendations for retraining every two years or longer. This systematic review studies the retention of adult ALS knowledge and skills following completion of an ALS course in healthcare providers. We retrieved original articles using Medline, CINAHL, Cochrane Library, and PubMed, and reviewed reference citations to identify additional studies. We extracted data from included articles using a structured approach and organized outcomes by evaluation method, and knowledge and skills retention. Among 336 articles retrieved, 11 papers were included. Most studies used multiple-choice questionnaires to evaluate knowledge retention and cardiac arrest simulation or other skills tests to evaluate skills retention. All studies reported variable rates of knowledge or skills deterioration over time, from 6 weeks to 2 years after training. Two studies noted retention of knowledge at 18 months and up to 2 years, and one reported skills retention at 3 months. Clinical experience, either prior to or after the courses, has a positive impact on retention of knowledge and skills. There is a lack of large well-designed studies examining the retention of adult ALS knowledge and skills in healthcare providers. The available evidence suggests that ALS knowledge and skills decay by 6 months to 1 year after training and that skills decay faster than knowledge. Additional studies are needed to help provide evidence-based recommendations for assessment of current knowledge and skills and need for refresher training to maximize maintenance of ALS competency.

    To describe the evolution of a provider order entry system with integrated decision support, from a research prototype to full implementation at one academic center, and finally to a commercial product. Describe the institutional environment and planning process in which the system originated. Highlight the historical evolution of the provider entry system, and analyze its system architecture and functionality. Describe the requirements for successful design and deployment both within a single health care organization and as part of a commercial product line. Over a period of eight years the system evolved from a research prototype to a fully integrated order entry system in routine use on most inpatient units of a large academic medical center. Around 12,000 orders are entered every day into the computer system; 70% of those are entered directly by the responsible physician. The system embeds best-of-care practice guidelines, and is used to reduce resource utilization by limiting unnecessary testing and suggesting more effective or less costly therapeutic replacements. The system was recently acquired by a large HIS software vendor and is being rapidly implemented at numerous customer sites. Large-scale development or deployment of complex health information systems requires considerable organizational agreement and resources, as well as close attention to iterative system design that explicitly includes constant feedback from the user community. The transformation of such a system from a single-site success to a widely deployed product requires convergence of resources and needs.

    The Austrian Soil Science Society (ASSS), founded in 1954, is a non-profit organisation aiming at furthering all branches of soil science in Austria. The ASSS provides information on the current state of soil research in Austria and abroad. It organizes annual conferences for scientists from soil and related sciences to exchange their recent studies and offers a journal for scientific publications. Annually, ASSS awards the Kubiena Research Prize for excellent scientific studies provided by young scientists. In order to conserve and improve soil science in the field, excursions are organized, also in cooperation with other scientific organisations. Due to well-established contacts with soil scientists and soil science societies in many countries, the ASSS is able to provide its members with information about the most recent developments in the field of soil science. This contributes to a broadening of the current scientific knowledge on soils. The ASSS also co-operates in the organisation of excursions and meetings with neighbouring countries. Several members of the ASSS teach soil science at various Austrian universities. More detail on said conferences, excursions, publications and awards will be given in the presentation. Beside its own scientific journal, published once or twice a year, and special editions such as guidebooks for soil classification, the ASSS runs a website providing information on the Society, its activities, meetings, publications, awards and projects. Together with the Environment Agency Austria the ASSS runs a soil platform on the internet. It is accessible for the public and thus informs society about soil issues. This platform offers a calendar with national and international soil events, contacts of soil related organisations and networks, information on national projects and publications. The society has access to products, information material and information on educational courses. Last but not least information on specific soil

    The Massachusetts Child Psychiatry Access Project (MCPAP) provides telephone support from mental health specialists to primary care providers (PCPs). Understanding PCPs' use may inform implementation of similar programs. We sought to examine PCPs' decision-making process to use or not use MCPAP when encountering mental health problems. We analyzed data regarding calls from PCPs to MCPAP from October 1, 2010, to July 31, 2011, and interviewed 14 PCPs with frequent use (≥7 calls) and infrequent use (≤4 calls). PCPs were asked about recent patients with mental health problems, and they were asked to describe reasons for calling or not calling MCPAP. Frequent callers were asked what sustained use; infrequent callers were asked about alternative management strategies. Comparisons were made between these groups in qualitative analysis. PCPs (n = 993) made 6526 calls (mean = 6.6; median = 3). Factors influencing calling included: MCPAP's guidance is timely and tailored to individual scope of practice; MCPAP's ability to arrange therapy referrals exceeds PCPs' ability; providing a plan at point of care relieves anxious families; and MCPAP's assistance helps accommodate families' preference to keep mental health in primary care. Some infrequent callers had gained skills through MCPAP before 2010 and now called only for complex cases. Other reasons for infrequent calling: PCPs have other consultation sources, have fear of being asked to manage more than they are comfortable, or have misperceptions of MCPAP's offerings. MCPAP enhanced PCPs' ability to deliver mental health care consistent with families' preferences. PCPs applied knowledge gained from calls to subsequent patients. Promoting MCPAP components through outreach and tailoring guidance to PCPs' scope of practice may entice greater use. Copyright © 2018. Published by Elsevier Inc.

    Mexico has had the Advanced Trauma Life Support (ATLS) program since 1986. We assessed the attrition of ATLS skills among ATLS providers and instructors in this country. Three groups (S, 16 students [new medical graduates enrolled for an ATLS course]; P, 33 providers; and I, 26 instructors [who had completed courses previously]) were evaluated. Group S read the manual before pretesting. Groups P and I were subdivided based on the length of time since the course had been completed: P1, less than 2 years (n = 22); P2, more than 2 years (n = 11); I1, less than 2 years (n = 16); and I2, more than 2 years (n = 10). Multiple-choice and psychomotor testing using ATLS scoring criteria were used. Affect was assessed post-ATLS for motivational factors, interactivity, and attitude toward trauma care. Multiple-choice test scores (means +/- SD) out of a maximum of 40 were as follows: S, 24.3 +/- 2.6; P1, 24.0 +/- 5.7; P2, 21.3 +/- 8.0; I1, 23.2 +/- 8.2; and I2, 24.0 +/- 7.2. Group S all passed the post-ATLS multiple-choice test (with correct answer percentages of 60.3% +/- 6.6% pre-ATLS versus 88.8% +/- 5.6% post-ATLS). An ATLS passing score of 80% correct answers was achieved in 2 of 33 for group P and 8 of 26 for group I (p ATLS group than in the P and I groups (p ATLS attitude to trauma care. Reading the manual alone yields similar cognitive but inferior psychomotor performance compared with subjects who completed the course previously. The majority of previous providers and instructors did not obtain a passing score (80%) in the multiple-choice test, but all the new providers passed the post-ATLS multiple-choice test, suggesting major attrition of cognitive skills but maintenance of psychomotor skills. Instructors had superior cognitive performance versus providers with worsening performance over time, but clinical skills performance was maintained at an equally high level by all groups. A very positive attitude toward ATLS prevailed among all participants.

    It has been proposed that the PST and PerioPredict genetic tests that are based on polymorphisms in interleukin 1 (IL-1) genes identify a subset of patients who experience fewer tooth extractions if provided with 2 annual preventive visits. Economic analyses indicate rationing preventive care to only "high-risk" genotypes, smokers, patients with diabetes, or combinations of these risk factors would reduce the cost of dental care by $4.8 billion annually in the United States. Data presented in the study that claimed clinical utility for the PST and PerioPredict tests were obtained for reanalysis using logistic regression to assess whether the PST genetic test, smoking, diabetes, or number of preventive visits were risk factors for tooth extraction during a span of 16 years. Consistency of risk classification by the PST (version 1) and PerioPredict (version 2) genetic tests was evaluated in different ethnic groups from the 1000 Genomes database. Multivariate analyses revealed association of tooth extraction with diabetes (P preventive visits (P = .004), but no support for the PST genetic test (P = .96) nor indication that the benefit of 2 preventive visits was affected by this genetic test (P = .58). Classification of risk was highly inconsistent between the PST (version 1) and PerioPredict (version 2) genetic tests. Two annual preventive visits were supported as beneficial for all patients, and there was no evidence that the IL-1 PST genetic test has any effect on tooth extraction risk or influences the benefits of 2 annual preventive visits. Neither IL-1 PST nor PerioPredict genetic tests are useful for rationing preventive dental care. Further research is needed to identify genetic biomarkers with robust clinical validity and clinical utility to effectively personalize the practice of dentistry.

    Although performance feedback has the potential to help clinicians improve the quality and safety of care, healthcare organizations generally lack knowledge about how this guidance is best provided. In low-resource settings, tools for theory-informed feedback tailoring may enhance limited clinical supervision resources. Our objectives were to establish proof-of-concept for computer-supported feedback message tailoring in Malawi, Africa. We conducted this research in five stages: clinical performance measurement, modeling the influence of feedback on antiretroviral therapy (ART) performance, creating a rule-based message tailoring process, generating tailored messages for recipients, and finally analysis of performance and message tailoring data. We retrospectively generated tailored messages for 7,448 monthly performance reports from 11 ART clinics. We found that tailored feedback could be routinely generated for four guideline-based performance indicators, with 35% of reports having messages prioritized to optimize the effect of feedback. This research establishes proof-of-concept for a novel approach to improving the use of clinical performance feedback in low-resource settings and suggests possible directions for prospective evaluations comparing alternative designs of feedback messages.

    Full Text Available The purpose of this editorial is to introduce the quantitative literacy community to the newly published A Handbook for Directors of Quantitative and Mathematics Centers. QMaSCs (pronounced “Q-masks” can be broadly defined as centers that have supporting students in quantitative fields of study as part of their mission. Some focus only on calculus or mathematics; others concentrate on numeracy or quantitative literacy, and some do all of that. A QMaSC may be embedded in a mathematics department, or part of a learning commons, or a stand-alone center. There are hundreds of these centers in the U.S. The new handbook, which is the outgrowth of a 2013 NSF-sponsored, national workshop attended by 23 QMaSC directors from all quarters of the U.S., is available open access on the USF Scholar Commons and in hard copy from Amazon.com. This editorial by the handbook’s editors provides background and overview of the 20 detailed chapters on center leadership and management; community interactions; staffing, hiring and training; center assessment; and starting a center; and then a collection of ten case studies from research universities, four-year state colleges, liberal arts colleges, and a community college. The editorial ends by pointing out the need and potential benefits of a professional organization for QMaSC directors.

    The European Commission has established a Nanomaterials Repository that hosts industrially manufactured nanomaterials that are distributed world-wide for safety testing of nanomaterials. In a first instance these materials were tested in the OECD Testing Programme. They have then also been tested in several EU funded research projects. The JRC Repository of Nanomaterials has thus developed into serving the global scientific community active in the nanoEHS (regulatory) research. The unique Repository facility is a state-of-the-art installation that allows customised sub-sampling under the safest possible conditions, with traceable final sample vials distributed world-wide for research purposes. This paper describes the design of the Repository to perform a semi-automated subsampling procedure, offering high degree of flexibility and precision in the preparation of NM vials for customers, while guaranteeing the safety of the operators, and environmental protection. The JRC nanomaterials are representative for part of the world NMs market. Their wide use world-wide facilitates the generation of comparable and reliable experimental results and datasets in (regulatory) research by the scientific community, ultimately supporting the further development of the OECD regulatory test guidelines.

    Knowing how stresses are dissipated on the fixed implant-supported complex allows adequate treatment planning and better choice of the materials used for prosthesis fabrication. Objectives The aim of this study was to evaluate the deformation suffered by cantilevered implant-supported fixed prostheses frameworks cast in silver-palladium alloy and coated with two occlusal veneering materials: acrylic resin or porcelain. Material and Methods Two strain gauges were bonded to the inferior surface of the silver-palladium framework and two other were bonded to the occlusal surface of the prosthesis framework covered with ceramic and acrylic resin on each of its two halves. The framework was fixed to a metallic master model and a 35.2 N compression force was applied to the cantilever at 10, 15 and 20 mm from the most distal implant. The measurements of deformation by compression and tension were obtained. The statistical 2-way ANOVA test was used for individual analysis of the experiment variables and the Tukey test was used for the interrelation between all the variables (material and distance of force application). Results The results showed that both variables had influence on the studied factors (deformation by compression and tension). Conclusion The ceramic coating provided greater rigidity to the assembly and therefore less distortion compared with the uncoated framework and with the resin-coated framework. The cantilever arm length also influenced the prosthesis rigidity, causing higher deformation the farther the load was applied from the last implant. PMID:25025562

    2016-12-01

    Decision making in terminal illness has recently received increased attention. In Japan, patients and their families typically make decisions without understanding either the severity of illness or the efficacy of life-supporting treatments at the end of life. Japanese culture traditionally directs the family to make decisions for the patient. This descriptive study examined the influence of the experiences of 391 Japanese nurses caring for dying patients and family members and how that experience changed their decision making for themselves and their family members. The results were mixed but generally supported the idea that the more experience nurses have in caring for the dying, the less likely they would choose to institute lifesupport measures for themselves and family members. The results have implications for discussions on end-of-life care. © The Author(s) 2016.

    The Edison Materials Technology Center (EMTEC) solicited and funded hydrogen infrastructure related projects that have a near term potential for commercialization. The subject technology of each project is related to the US Department of Energy hydrogen economy goals as outlined in the multi-year plan titled, 'Hydrogen, Fuel Cells and Infrastructure Technologies Program Multi-Year Research, Development and Demonstration Plan.' Preference was given to cross cutting materials development projects that might lead to the establishment of manufacturing capability and job creation. The Edison Materials Technology Center (EMTEC) used the US Department of Energy hydrogen economy goals to find and fund projects with near term commercialization potential. An RFP process aligned with this plan required performance based objectives with go/no-go technology based milestones. Protocols established for this program consisted of a RFP solicitation process, white papers and proposals with peer technology and commercialization review (including DoE), EMTEC project negotiation and definition and DoE cost share approval. Our RFP approach specified proposals/projects for hydrogen production, hydrogen storage or hydrogen infrastructure processing which may include sensor, separator, compression, maintenance, or delivery technologies. EMTEC was especially alert for projects in the appropriate subject area that have cross cutting materials technology with near term manufacturing and commercialization opportunities.

  5. Thermal desorption GC-MS as a tool to provide PAH certified standard reference material on particulate matter quartz filters.

    2013-02-15

    Reference materials for particulate matter (PM) on filter media are not available for the quantification of polycyclic aromatic hydrocarbons (PAHs) in ambient air. This is due to the difficulty of obtaining reference material that has a homogeneous distribution on a filter surface that is large enough for characterization and distribution. High volume sample filters from different locations and seasons were considered to validate the feasibility of the use of quartz filters as reference material for PAH concentrations. A rapid thermal desorption (TD) technique coupled with gas chromatography/mass spectroscopy was applied to characterise the material for the content of fifteen different PAHs. TD technique allowed for rapid and accurate analysis of small sections of filter (5mm diameter), leaving enough material for the production of twenty sub-filter cuts (42 mm diameter) that could be used for distribution and control. Stability and homogeneity tests required for material certification were performed as indicated by the ISO guide 34:2009 and ISO 35:2006. The contribution of the heterogeneous distribution of PAHs on the filter surface resulted generally lower than 10% and higher for more volatile PAHs. One year of storage at -18°C indicated no significant variation in PAH concentrations. Nevertheless, a methodology for shipping and storing of the filter material at ambient temperature in especially designed plastic envelopes, was also shown to allow for stabile concentrations within twenty days. The method accuracy was confirmed by the analysis of NIST SRM 1649a (urban dust) and PAH concentrations were validated against the reference values obtained from an inter-laboratory exercise. In the case of benzo[a]pyrene for masses quantified between 100 pg and 10 ng the TD method provided expanded uncertainties of circa 10%, while the inter-laboratory reference value uncertainties ranged between 15 and 20%. The evaluation of these results supports the use of the presented

    Analysis of images of biotinylated Escherichia coli 70S ribosome particles, bound to streptavidin affinity grids, demonstrates that the image-quality of particles can be predicted by the image-quality of the monolayer crystalline support film. Also, the quality of the Thon rings is a good predictor of the image-quality of particles, but only when images of the streptavidin crystals extend to relatively high resolution. When the estimated resolution of streptavidin was 5 Å or worse, for example, the ribosomal density map obtained from 22,697 particles went to only 9.5 Å, while the resolution of the map reached 4.0 Å for the same number of particles, when the estimated resolution of streptavidin crystal was 4 Å or better. It thus is easy to tell which images in a data set ought to be retained for further work, based on the highest resolution seen for Bragg peaks in the computed Fourier transforms of the streptavidin component. The refined density map obtained from 57,826 particles obtained in this way extended to 3.6 Å, a marked improvement over the value of 3.9 Å obtained previously from a subset of 52,433 particles obtained from the same initial data set of 101,213 particles after 3-D classification. These results are consistent with the hypothesis that interaction with the air-water interface can damage particles when the sample becomes too thin. Finally, streptavidin monolayer crystals appear to provide a good indication of when that is the case.

    To provide a good understanding of many abstract concepts in the field of electricity above that of their students is often a major challenge for secondary school teachers. Many educational researchers promote conceptual learning as a teaching approach that can help teachers to achieve this goal. In this paper, we present Physlet-based materials for supporting conceptual learning about electricity. To conduct research into the effectiveness of these materials, we designed two different physics courses: one group of students, the experimental group, was taught using Physlet-based materials and the second group of students, the control group, was taught using expository instruction without using Physlets. After completion of the teaching, we assessed students' thinking skills and analysed the materials with an independent t test, multiple regression analyses and one-way analysis of covariance. The test scores were significantly higher in the experimental group than in the control group ( p < 0.05). The results of this study confirmed the effectiveness of conceptual learning about electricity with the help of Physlet-based materials.

    Background It is likely that calls for disaster medical assistance teams (DMATs) continue in response to international disasters. As part of a national survey, the present study was designed to evaluate the Australian DMAT experience and the need for logistic support. Methods Data were collected via an anonymous mailed survey distributed via State and Territory representatives on the Australian Health Protection Committee, who identified team members associated with Australian DMAT deployments from the 2004 Asian Tsunami disaster. Results The response rate for this survey was 50% (59/118). Most of the personnel had deployed to the South East Asian Tsunami affected areas. The DMAT members had significant clinical and international experience. There was unanimous support for dedicated logistic support with 80% (47/59) strongly agreeing. Only one respondent (2%) disagreed with teams being self sufficient for a minimum of 72 hours. Most felt that transport around the site was not a problem (59%; 35/59), however, 34% (20/59) felt that transport to the site itself was problematic. Only 37% (22/59) felt that pre-deployment information was accurate. Communication with local health providers and other agencies was felt to be adequate by 53% (31/59) and 47% (28/59) respectively, while only 28% (17/59) felt that documentation methods were easy to use and reliable. Less than half (47%; 28/59) felt that equipment could be moved easily between areas by team members and 37% (22/59) that packaging enabled materials to be found easily. The maximum safe container weight was felt to be between 20 and 40 kg by 58% (34/59). Conclusions This study emphasises the importance of dedicated logistic support for DMAT and the need for teams to be self sufficient for a minimum period of 72 hours. There is a need for accurate pre deployment information to guide resource prioritisation with clearly labelled pre packaging to assist access on site. Container weights should be restricted to between

    Extracorporeal membrane oxygenation (ECMO) is being increasingly used as a bridge to lung transplantation. Small, single-institution series have described increased success using ECMO in spontaneously breathing patients compared with patients on ECMO with mechanical ventilation, but this strategy has not been evaluated on a large scale. Using the United Network for Organ Sharing database, all adult patients undergoing isolated lung transplantation from May 2005 through September 2013 were identified. Patients were categorized by their type of pretransplant support: no support, ECMO only, invasive mechanical ventilation (iMV) only, and ECMO + iMV. Kaplan-Meier survival analysis with log-rank testing was performed to compare survival based on type of preoperative support. A Cox regression model was used to determine whether type of preoperative support was independently associated with survival, using previously established predictors of survival as covariates. Approximately 12,403 primary adult pulmonary transplantations were included in this analysis. Sixty-five patients (0.52%) were on ECMO only, 612 (4.93%) required only iMV, 119 (0.96%) were on ECMO + iMV, and the remaining 11,607 (94.6%) required no invasive support before transplantation. One-year survival was decreased in all patients requiring support, regardless of type. However, mid-term survival was similar between patients on ECMO alone and those not on support but significantly worse with patients requiring iMV only or ECMO + iMV. In multivariable analysis, ECMO + iMV and iMV alone were independently associated with decreased survival compared with nonsupport patients, whereas ECMO alone was not significant. In patients with worsening pulmonary disease awaiting lung transplantation, those supported via ECMO with spontaneous breathing demonstrated improved survival compared with other bridging strategies.

    Adult-provided supportive language facilitates memory for the past in preverbal and verbal children. Work conducted with 18-month-olds indicates that children benefit from supportive adult language when tested after a 4-week delay but not when tested immediately after sequence demonstration; moreover, findings reveal that supportive language provided only at test may be more facilitative of recall after a delay relative to supportive language provided only at encoding. In the present study, we examined whether child language comprehension abilities moderated the extent to which preverbal children benefitted from supportive language provided at encoding and test. The findings indicated that child language comprehension and supportive language provided at encoding were unassociated with performance at baseline or immediate imitation; however, the moderating effect of child language comprehension on adult-provided supportive language at encoding and test was observed after a 1-week delay. Correlations revealed continuous associations between general comprehension scores and recall performance after the 1-week delay on sequences presented in the most supportive condition at encoding. Taken together, the presented findings reveal that the complex interplay between language and cognition is established in early childhood, with foundational relations emerging before children are capable of verbally reporting on the past.

    Midha, Varsha; Jha, M K; Dey, Apurba

    2012-01-01

    A continuous fluidized bed bioreactor (FBBR) with nylon support particles was used to treat synthetic sulfide wastewater at different hydraulic retention time of 25, 50 and 75 min and upflow velocity of 14, 17 and 20 m/hr. The effects of upflow velocity, hydraulic retention time and reactor operation time on sulfide oxidation rate were studied using statistical model. Mixed culture obtained from the activated sludge, taken from tannery effluent treatment plant, was used as a source for microorganisms. The diameter and density of the nylon particles were 2-3 mm and 1140 kg/m3, respectively. Experiments were carried out in the reactor at a temperature of (30 +/- 2) degrees C, at a fixed bed height of 16 cm after the formation of biofilm on the surface of support particles. Biofilm thickness reached (42 +/- 3) microm after 15 days from reactor start-up. The sulfide oxidation, sulfate and sulfur formation is examined at all hydraulic retention times and upflow velocities. The results indicated that almost 90%-92% sulfide oxidation was achieved at all hydraulic retention times. Statistical model could explain 94% of the variability and analysis of variance showed that upflow velocity and hydraulic retention time slightly affected the sulfide oxidation rate. The highest sulfide oxidation of 92% with 70% sulfur was obtained at hydraulic retention time of 75 min and upflow velocity of 14 m/hr.

    2017-07-01

    Full Text Available With the increasing demands of world biotechnology industries there is a need to enhance the productivity reaction stability reusability and shelf life of enzymes. So novel techniques are required to facilitate large scale and economic formulations. Enzyme immobilization is done in order to meet all the challenges to enzyme activity. It provides an excellent base for increasing availability of enzyme to the substrate with greater turn over a considerable period of time. This can be done by entrapment support binding cross linking of enzyme crystals etc. Several natural and synthetic support materials are used for the immobilization of enzymes. These increase the efficiency of an enzyme to a great extent. Nowadays immobilized enzymes are preferred over their free counterpart due to their prolonged availability. Immobilized enzymes are widely used in pharmaceutical industries cosmetic industries food processing biofuel production and many other sectors.

    This paper evaluates program, workplace and process factors associated with implementation and sustainment of an evidence-based parenting support program (EBP) in disadvantaged communities. Correlation analyses and binary logistic regressions were used to assess the associations between key implementation support factors and program implementation (at 18 months) and sustainment (at 36 months) post training with (N=35) Australian Aboriginal and Torres Strait Islander family support providers using the Triple P - Positive Parenting Program in Indigenous child protection agencies. This study demonstrated that for implementation at 18 months, there was a trend for implementing providers to report higher levels of partnership support, perceived program benefit, workplace support and workplace cohesion. However, the only significant relationship was with partnership support (r=.31 pprogram implementation. For sustained implementation at 36 months, no relationship was found between sustainment and program characteristics, workplace characteristics, supervision and peer support or sustainability planning. Supportive coaching was the only significant correlate (r=0.46, pp=0.009] in the program sustainment model. Overall, these findings suggest the need for further exploration of program and workplace variables and provide evidence to consider incorporating partnership support and supportive coaching in real world implementation models to improve the likelihood of EBP implementation and sustainment in Indigenous communities.

    To examine the impact of errors or adverse events on emotional distress and professional quality of life in healthcare providers in the neonatal intensive care unit, and the moderating role of coworker support. Errors or adverse events can result in negative outcomes for healthcare providers. However, the role of coworker support in improving emotional and professional outcomes has not been examined. A cross-sectional online survey from a quality improvement initiative to train peer supporters in a neonatal intensive care unit. During 2015, 463 healthcare providers in a neonatal intensive care unit completed a survey assessing their experiences with an error or adverse event, anxiety, depression, professional quality of life and coworker support. Compared with those who did not experience an error or adverse event (58%), healthcare providers who observed (23%) or were involved (19%) in an incident reported higher levels of anxiety and secondary traumatic stress. Those who were involved in an event reported higher levels of depression and burnout. Differences between the three groups (no event, observation and involvement) for compassion satisfaction were non-significant. Perceived coworker support moderated the association between experiencing an event and both anxiety and depression. Specifically, experiencing an event was associated with higher levels of anxiety and depression when coworkers were perceived as low in supportiveness, but not when they were viewed as highly supportive. Findings suggest that errors or adverse events can have a harmful impact on healthcare providers and that coworker support may reduce emotional distress. © 2017 John Wiley & Sons Ltd.

    Full Text Available A pilot anaerobic reactor was installed to remove the organic load of wastewater from dairy industry. It uses a bacterial inoculum previously acclimated to the substrate. It was disposed horizontally and filled with pieces of polyethylene terephthalate (PET, from plastic bottles. The reactor was operated at room temperature, during 100 days, in three phases: 1 the reactor was stabilized with volumetric organic load from 0.013 to 0.500 kg/day.m³; 2 the hydraulic retention time was of 1 day and the volumetric organic load of 3 kg/day.m³; 3 the volumetric organic load was incremented from 4 to 6.6 kg/day.m³ and the hydraulic retention time was 1 day. Organic material removal efficiencies was of 85%, and approximately 75% were obtained in the second and third phase, respectively. The Y value was 0.15, indicating that 0.15 kg of biomass were generated by kg of QDO supplied to the reactor. Finally, the biomass generated inside the reactor was analyzed, obtaining a value of 18868 mg/L, which is a higher value than those of conventional systems.

  8. Potential For Plug-In Electric Vehicles To Provide Grid Support Services

    2017-04-01

    Since the modern-day introduction of plug-in electric vehicles (PEVs), scientists have proposed leveraging PEV battery packs as distributed energy resources for the electric grid. PEV charging can be controlled not only to provide energy for transportation but also to provide grid services and to facilitate the integration of renewable energy generation. With renewable generation increasing at an unprecedented rate, most of which is non-dispatchable and intermittent, the concept of using PEVs as controllable loads is appealing to electric utilities. This additional functionality could also provide value to PEV owners and drive PEV adoption. It has been widely proposed that PEVs can provide valuable grid services, such as load shifting to provide voltage regulation. The objective this work is to address the degree to which PEVs can provide grid services and mutually benefit the electric utilities, PEV owners, and auto manufacturers.

  9. Materials study supporting thermochemical hydrogen cycle sulfuric acid decomposer design

    Science.gov (United States)

    Peck, Michael S.

    Increasing global climate change has been driven by greenhouse gases emissions originating from the combustion of fossil fuels. Clean burning hydrogen has the potential to replace much of the fossil fuels used today reducing the amount of greenhouse gases released into the atmosphere. The sulfur iodine and hybrid sulfur thermochemical cycles coupled with high temperature heat from advanced nuclear reactors have shown promise for economical large-scale hydrogen fuel stock production. Both of these cycles employ a step to decompose sulfuric acid to sulfur dioxide. This decomposition step occurs at high temperatures in the range of 825°C to 926°C dependent on the catalysis used. Successful commercial implementation of these technologies is dependent upon the development of suitable materials for use in the highly corrosive environments created by the decomposition products. Boron treated diamond film was a potential candidate for use in decomposer process equipment based on earlier studies concluding good oxidation resistance at elevated temperatures. However, little information was available relating the interactions of diamond and diamond films with sulfuric acid at temperatures greater than 350°C. A laboratory scale sulfuric acid decomposer simulator was constructed at the Nuclear Science and Engineering Institute at the University of Missouri-Columbia. The simulator was capable of producing the temperatures and corrosive environments that process equipment would be exposed to for industrialization of the sulfur iodide or hybrid sulfur thermochemical cycles. A series of boron treated synthetic diamonds were tested in the simulator to determine corrosion resistances and suitability for use in thermochemical process equipment. These studies were performed at twenty four hour durations at temperatures between 600°C to 926°C.

    Read, Kevin; LaPolla, Fred Willie Zametkin

    2018-01-01

    REDCap, an electronic data capture tool, supports good research data management, but many researchers lack familiarity with the tool. While a REDCap administrator provided technical support and a clinical data management support unit provided study design support, a service gap existed. Librarians with REDCap expertise sought to increase and improve usage through outreach, workshops, and consultations. In collaboration with a REDCap administrator and the director of the clinical data management support unit, the role of the library was established in providing REDCap training and consultations. REDCap trainings were offered to the medical center during the library's quarterly data series, which served as a springboard for offering tailored REDCap support to researchers and research groups. Providing REDCap support has proved to be an effective way to associate the library with data-related activities in an academic medical center and identify new opportunities for offering data services in the library. By offering REDCap services, the library established strong partnerships with the Information Technology Department, Clinical Data Support Department, and Compliance Office by filling in training gaps, while simultaneously referring users back to these departments when additional expertise was required. These new partnerships continue to grow and serve to position the library as a central data hub in the institution.

Programmatic modifications may involve communication, linguistic, and grading issues, and both the listening and physical settings. Curricular modifications may involve the classroom structure, rapport and affect, the instructional format and language, the lesson format and materials, comprehension monitoring, activity and assignment completion, and placement choices. Professionals should work cooperatively to make and monitor changes.

The Radioactive Waste Technical Support Program entered completed questionnaires into a database and analyzed them for quantities and type of materials stored. This report discusses the data that TSP gathered. The report also discusses problems revealed by the questionnaires and future uses of the data. Appendices contain selected data about material reported.

  5. Providing support for problem-based learning in dentistry: the Manchester experience.

    The introduction of problem-based learning (PBL) into any programme demands a period of adjustment on the part of faculty. Similarly, students new to PBL take time to adapt to what is, for the majority of them, an unfamiliar mode of learning. At Manchester, closed loop PBL is used throughout the first and second years of the dental programme; the method is interdisciplinary; there are no subject boundaries. Dental students work in groups of between 10 and 15, facilitated by a tutor from the Department of Biological Sciences, to research topics and share information in a mutually supportive environment. Each week a different problem forms the focus for learning. In this paper, we seek to describe the measures introduced in response to student feedback collected via routine meetings with the senior tutor, after meetings with their academic or personal tutors and through discussion at the staff students' committee, which we at Manchester have taken to facilitate the process of adaptation to PBL. Changes have been made in the areas of recruitment, pre-admission interviewing, induction (development of an induction booklet and communication skills module) and tutorial support (overhaul of personal tutor system and introduction of peer-assisted study (PAS) and personal and academic development programmes (PADPs)). Feedback on these changes, gathered via the routes described above, has been positive and continues to be central to our processes of development in these areas. Although the various ways in which PBL has been implemented worldwide may place limits on the transferability of our methods, this paper serves to illustrate some of the means available to support students in the transition to self-directed learning. The latter is not only an essential component of PBL but also something we should be seeking to foster in all students, no matter what philosophy and method of course delivery are utilized.

    The authors have developed a simple method for specifying rules to be applied to information on HTML forms. This approach allows clinical experts, who lack the programming expertise needed to write CGI scripts, to construct and maintain domain-specific knowledge and ordering capabilities within WizOrder, the order-entry and decision support system used at Vanderbilt Hospital. The clinical knowledge base maintainers use HTML editors to create forms and spreadsheet programs for rule entry. A test environment has been developed which uses Netscape to display forms; the production environment displays forms using an embedded browser.

    A vital strategy to educate future geoscientists is to support faculty at the beginning of their careers, thus catalyzing a career-long impact on the early-career faculty and on their future students. New faculty members are at a pivotal stage in their careers as they step from being research-focused graduate students and post-doctoral scholars, under the guidance of advisors, towards launching independent careers as professors. New faculty commonly, and not unexpectedly, feel overwhelmed as they face challenges to establish themselves in a new environment, prepare new courses, begin new research, and develop a network of support. The workshop for Early Career Geoscience Faculty: Teaching, Research, and Managing Your Career has been offered annually in the U.S. since 1999. The workshop is currently offered through the National Association of Geoscience Teachers On the Cutting Edge professional development program with support from the NSF, AGU and GSA. This five-day workshop, with associated web resources, offers guidance for incorporating evidence-based teaching practices, developing a research program, and managing professional responsibilities in balance with personal lives. The workshop design includes plenary and concurrent sessions, individual consultations, and personalized feedback from workshop participants and leaders. Since 1999, more than 850 U.S. faculty have attended the Early Career Geoscience Faculty workshop. Participants span a wide range of geoscience disciplines, and are in faculty positions at two-year colleges, four-year colleges, comprehensive universities and research universities. The percentages of women (~50%) and underrepresented participants (~8%) are higher than in the general geoscience faculty population. Multiple participants each year are starting positions after receiving all or part of their education outside the U.S. Collectively, participants report that they are better prepared to move forward with their careers as a result of

    2013-08-01

    Full Text Available The anterior thalamic nuclei, a central component of Papez’ circuit, are generally assumed to be key constituents of the neural circuits responsible for certain categories of learning and memory. Supporting evidence for this contention is that damage to either of two brain regions, the medial temporal lobe and the medial diencephalon, is most consistently associated with anterograde amnesia. Within these respective regions, the hippocampal formation and the anterior thalamic nuclei (anteromedial, anteroventral, anterodorsal are the particular structures of interest. The extensive direct and indirect hippocampal-anterior thalamic interconnections and the presence of theta-modulated cells in both sites further support the hypothesis that these structures constitute a neuronal network crucial for memory and cognition. The major tool in understanding how the brain processes information is the analysis of neuronal output at each hierarchical level along the pathway of signal propagation coupled with neuroanatomical studies. Here, we discuss the electrophysiological properties of cells in the anterior thalamic nuclei with an emphasis on their role in spatial navigation. In addition, we describe neuroanatomical and functional relationships between the anterior thalamic nuclei and hippocampal formation.

    Colloidal particles dispersed in liquid crystals can form new materials with tunable elastic and electro-optic properties. In a periodic ‘blue phase’ host, particles should template into colloidal crystals with potential uses in photonics, metamaterials and transformational optics. Here we show by computer simulation that colloid/cholesteric mixtures can give rise to regular crystals, glasses, percolating gels, isolated clusters, twisted rings and undulating colloidal ropes. This structure can be tuned via particle concentration, and by varying the surface interactions of the cholesteric host with both the particles and confining walls. Many of these new materials are metastable: two or more structures can arise under identical thermodynamic conditions. The observed structure depends not only on the formulation protocol but also on the history of an applied electric field. This new class of soft materials should thus be relevant to design of switchable, multistable devices for optical technologies such as smart glass and e-paper.

  12. Fostering a supportive moral climate for health care providers: Toward cultural safety and equity

    Directory of Open Access Journals (Sweden)

    Adel F. Almutairi

    Full Text Available In Western forms of health care delivery around the globe, research tells us that nurses experience excessive workloads as they face increasingly complex needs in the populations they serve, professional conflicts, and alienation from leadership in health care bureaucracies. These problems are practical and ethical as well as cultural. Cultural conflicts can arise when health care providers and the populations they serve come from diverse economic, ethnic, and cultural backgrounds. The purpose in this paper is to draw from Almutairi’s research with health care teams in Saudi Arabia to show the complexity of culturally and morally laden interactions between health care providers and patients and their families. Then, I will argue for interventions that promote social justice and cultural safety for nurses, other health care providers, and the individuals, families, and communities they serve. This will include addressing international implications for nursing practice, leadership, policy and research. Keywords: Moral climate, Social justice, Equity, Cultural diversity

    2016-02-01

    Parenting during family medicine residency is increasingly common. Relatively little is known about how the competing demands of work and family life affect residents. We conducted an exploratory qualitative study of parenting family medicine residents at one program in the Midwest utilizing focus groups to understand residents' perceptions of the positive and negative characteristics of their roles as physicians and parents. We used consensus coding to identify themes in the data and then developed a model to illustrate the relationships among the identified themes. Competing demands on their time require parenting family medicine residents to often make difficult choices, which result in both positive and negative outcomes for residents, their families, and their residency experience. Parenting family medicine residents experience numerous conflicts in their concurrent roles of learner, physician, and parent. Parenting-friendly residency training programs would likely offer valuable support for these individuals during this stressful life period.

    2015-09-01

    This handbook is an update of the 1993 version of the Data Collection Handbook and the Radionuclide Transfer Factors Report to support modeling the impact of radioactive material in soil. Many new parameters have been added to the RESRAD Family of Codes, and new measurement methodologies are available. A detailed review of available parameter databases was conducted in preparation of this new handbook. This handbook is a companion document to the user manuals when using the RESRAD (onsite) and RESRAD-OFFSITE code. It can also be used for RESRAD-BUILD code because some of the building-related parameters are included in this handbook. The RESRAD (onsite) has been developed for implementing U.S. Department of Energy Residual Radioactive Material Guidelines. Hydrogeological, meteorological, geochemical, geometrical (size, area, depth), crops and livestock, human intake, source characteristic, and building characteristic parameters are used in the RESRAD (onsite) code. The RESRAD-OFFSITE code is an extension of the RESRAD (onsite) code and can also model the transport of radionuclides to locations outside the footprint of the primary contamination. This handbook discusses parameter definitions, typical ranges, variations, and measurement methodologies. It also provides references for sources of additional information. Although this handbook was developed primarily to support the application of RESRAD Family of Codes, the discussions and values are valid for use of other pathway analysis models and codes.

    Despite the number of interprofessional team members caring for children at the end of life, little evidence exists on how institutions can support their staff in providing care in these situations. We sought to evaluate which aspects of the hospital work environment were most helpful for multidisciplinary team members who care for patients at the end of life and identify areas for improvement to better address staff needs. Qualitative thematic analysis was completed of free-text comments from a survey distributed to interprofessional staff members involved in the care of a recently deceased pediatric patient. A total of 2701 surveys were sent; 890 completed. Free-text responses were provided by 306 interprofessional team members. Interprofessional team members involved in the care of a child who died at a 348 bed academic children's hospital in the Midwestern United States. Realist thematic analysis of free-text responses was completed in Dedoose using a deductive and inductive approach with line-by-line coding. Descriptive statistics of demographic information was completed using Excel. Thematic analysis of the 306 free-text responses identified three main support-related themes. Interprofessional team members desire to have (1) support through educational efforts such as workshops, (2) support from colleagues, and (3) support through institutional practices. Providers who participate in end-of-life work benefit from ongoing support through education, interpersonal relationships, and institutional practices. Addressing these areas from an interprofessional perspective enables staff to provide the optimal care for patients, patients' families, and themselves.

    This study proposes mechanical and hydrodynamic characterization of rock wool used as support material in compact filter. A double-pronged approach, based on experimental simulation of various physical states of this material was done. First of all a scanning electron microscopy observation allows to highlight the fibrous network structure, the fibres sizing distribution and the atomic absorption spectrum. The material was essentially lacunar with 97 ± 2% of void space. Static compression tests on variably saturated rock wool samples provide the fact that the strain/stress behaviours depend on both the sample conditioning and the saturation level. Results showed that water exerts plastifying effect on mechanical behaviour of rock wool. The load-displacement curves and drainage evolution under different water saturation levels allowed exhibiting hydraulic retention capacities under stress. Finally, several tracer experiments on rock wool column considering continuous and batch feeding flow regime allowed: (i) to determine the flow model for each test case and the implications for water dynamic in rock wool medium, (ii) to assess the rock wool double porosity and discuss its advantages for wastewater treatment, (iii) to analyse the benefits effect for water treatment when the high level of rock wool hydric retention was associated with the plug-flow effect, and (iv) to discuss the practical contributions for compact filter conception and management.

    Decision-aid systems, likely to appear in future aircraft generations, could play a central role in the cockpit thanks to the broad spectrum of functionalities and decision support facilities they will offer to the crew. As part of such systems, the exploratory FINDER mock-up is a knowledge based system (KBS) designed to help crew members continually optimize their flight plan by suggesting solutions considering exhaustive information related to flight context, either on pilot request or upon external information occurrence. The successful evaluation by Air France pilots of that first mock-up dedicated to diversion procedure on pilot request has led to the current development of an enhanced system with nominal enroute operations and real-time capabilities. Nominal enroute operations concern the optimization with respect to an evolutive constraining of favoring environment (due to weather, traffic or regulated areas, and ETOPS constraints). This study paves the way for a future flight assistant system concept which is already under investigation and may take place in SEXTANT Avionique's future development steps.

    Despite high frequencies of multiple, life-limiting conditions relating to palliative care needs, people who are homeless are one of the most underserved and rarely encountered groups in palliative care settings. Instead, they often die in care places where palliative competence is not available. In this qualitative single-case study, we explored the conditions and practices of palliative care from the perspective of staff at a Swedish support home for homeless people. Interpretive description guided the research process, and data were generated from repeated reflective conversations with staff in groups, individually, and in pairs. The findings disclose a person-centered approach to palliative care, grounded in the understanding of the person's health/illness and health literacy, and how this is related to and determinant on life as a homeless individual. Four patterns shape this approach: building trustful and family-like relationships, re-dignifying the person, re-considering communication about illness and dying, and re-defining flexible and pragmatic care solutions. © The Author(s) 2015.

    Full Text Available While flood risk is evolving as one of the most imminent natural hazards and the shift from a reactive decision environment to a proactive one sets the basis of the latest thinking in flood management, the need to equip decision makers with necessary tools to think about and intelligently select options and strategies for flood management is becoming ever more pressing. Within this context, the Preparing for Extreme and Rare Events in Coastal Regions (PEARL intelligent knowledge-base (PEARL KB of resilience strategies is presented here as an environment that allows end-users to navigate from their observed problem to a selection of possible options and interventions worth considering within an intuitive visual web interface assisting advanced interactivity. Incorporation of real case studies within the PEARL KB enables the extraction of (evidence-based lessons from all over the word, while the KB’s collection of methods and tools directly supports the optimal selection of suitable interventions. The Knowledge-Base also gives access to the PEARL KB Flood Resilience Index (FRI tool, which is an online tool for resilience assessment at a city level available to authorities and citizens. We argue that the PEARL KB equips authorities with tangible and operational tools that can improve strategic and operational flood risk management by assessing and eventually increasing resilience, while building towards the strengthening of risk governance. The online tools that the PEARL KB gives access to were demonstrated and tested in the city of Rethymno, Greece.

    Ice recrystallization is of great importance to both fundamental research and practical applications, however understanding and controlling ice recrystallization processes remains challenging. Here, we report the discovery of an ion-specific effect on ice recrystallization. By simply changing the initial type and concentration of ions in an aqueous solution, the size of ice grains after recrystallization can be tuned from 27.4+/-4.1 to 277.5+/-30.9 μm. Molecular dynamics simulations show that the ability of the ion to be incorporated into the ice phase plays a key role in the ultimate size of the ice grains after recrystallization. Moreover, by using recrystallized ice crystals as templates, 2D and 3D porous networks with tuneable pore sizes could be prepared from various materials, for example, NaBr, collagen, quantum dots, silver and polystyrene colloids. These porous materials are suitable for a wide range of applications, for example, in organic electronics, catalysis and bioengineering.

    Little is known about the impact of educative media reports on the intention to provide help to suicidal individuals and on suicide-related knowledge. To test whether material debunking widely shared myths influences knowledge and the intention to provide adequate help to others, and if such information reduces reading enjoyment. A randomized controlled trial was utilized. Participants allocated to the intervention group were exposed to awareness material explicitly addressing suicide myths. Analyses show that exposure to printed awareness material increased knowledge, which in turn positively influenced intentions to provide help. The inclusion of information regarding suicide myths did not reduce reading enjoyment. The awareness material used in this study only addressed two suicide myths that were considered to be especially important. Information debunking suicide myths in suicide-related media reports is therefore both feasible and potentially helpful.

    Full Text Available Alessandra N Bazzano,1 Lisa Littrell,1 Amelia Brandt,1 Shelley Thibeau,2 Kamala Thriemer,3 Katherine P Theall1 1Department of Global Community Health and Behavioral Sciences, Tulane University School of Public Health and Tropical Medicine, 2Ochsner Health System, New Orleans, LA, USA; 3MLT EpiConsult, Jingili, NT, Australia Background: Exclusive breastfeeding for infants up to 6 months is widely recommended, yet breastfeeding rates are relatively low in the US. The most common reason women stop breastfeeding early is a perceived insufficiency of milk. Galactagogues are herbal and pharmaceutical products that can help increase milk supply; however, data on their efficacy and safety is limited. Lactation consultants, obstetricians, and other health providers are an important point of contact for breastfeeding women experiencing challenges with lactation. This study explored providers’ perceptions, experiences, and practices in relation to galactagogue recommendation. Method: A cross-sectional survey was conducted among a convenience sample of English-speaking health providers in the US who counsel breastfeeding women and their infants. Results: More than 70% of respondents reported to recommend galactagogues. The most frequently recommended galactagogue was fenugreek with respondents indicating that they recommend it either ‘always’ (8.5% or ‘most of the time’ (14.9% and ‘sometimes’ (46.8%. More than 80% of the respondents indicated that galactagogues were useful for their clients and only one-third reported side effects. Reasons for refraining from recommending galactagogues were insufficient evidence of its efficacy and safety. Respondents reported a wide variety of sources of information used for their own education about galactagogues. Discussion: Despite little evidence regarding safety and efficacy, some galactagogues are widely recommended and often perceived to be useful. However, concerns about their efficacy and safety

Content was developed and then evaluated by caregivers residing in 3 countries. Findings suggest trends that exposure to information may be related to a higher sense of mastery and a reduction of depressive symptomatology.

    The paper examines the influence of religion on attitudes, behaviors, and HIV infection among rural adolescent women in Zimbabwe. We analyzed data from a 2007 to 2010 randomized controlled trial in rural eastern Zimbabwe testing whether school support can prevent HIV risk behaviors and related attitudes among rural adolescent orphan girls; supplementary data from the 2006 Zimbabwe Demographic and Health Survey (ZDHS) were also analyzed. The present study design is largely cross-sectional, using the most recent available survey data from the clinical trial to examine the association between religious affiliation and religiosity on school dropout, marriage, and related attitudes, controlling for intervention condition, age and orphan type. The ZDHS data examined the effect of religious denomination on marriage and HIV status among young rural women, controlling for age. Apostolic Church affiliation greatly increased the likelihood of early marriage compared to reference Methodist Church affiliation (odds ratio = 4.5). Greater religiosity independently reduced the likelihood of school dropout, increased gender equity attitudes and disagreement with early sex, and marginally reduced early marriage. Young rural Apostolic women in the ZDHS were nearly four times as likely to marry as teenagers compared to Protestants, and marriage doubled the likelihood of HIV infection. Findings contradict an earlier seminal study that Apostolics are relatively protected from HIV compared to other Christian denominations. Young Apostolic women are at increased risk of HIV infection through early marriage. The Apostolic Church is a large and growing denomination in sub-Saharan Africa and many Apostolic sects discourage medical testing and treatment in favor of faith healing. Since this can increase the risk of undiagnosed HIV infection for young married women and their infants in high prevalence areas, further study is urgently needed to confirm this emerging public health problem

    3D printing technology has been used for rapid prototyping since 1980's and is still developing in a way that can be used for customized products with complex design and miniature features. Among all the available 3D printing techniques, Fused Deposition Modeling (FDM) is one of the most widely used technologies because of its capability to build different structures by employing various materials. However, complexity of parts made by FDM is greatly limited by restriction of using support materials. Support materials are often used in FDM for several complex geometries such as fully suspended shapes, overhanging surfaces and hollow features. This paper describes an approach to 3D print a structure using silicone elastomer and polylactide fiber (PLA) by employing a novel support material that is soluble in water. This support material is melted sugar which can easily be prepared at a low cost. Sugar is a carbohydrate, which is found naturally in plants such as sugarcane and sugar beets; therefore, it is completely organic and eco-friendly. As another advantage, the time for removing this material from the part is considerably less than other commercially available support materials and it can be removed easily by warm water without leaving any trace. Experiments were done using an inexpensive desktop 3D printer to fabricate complex structures for use in soft robots. The results envision that further development of this system would contribute to a method of fabrication of complex parts with lower cost yet high quality.

  17. Ketosteroid isomerase provides further support for the idea that enzymes work by electrostatic preorganization.

    One of the best systems for exploring the origin of enzyme catalysis has been the reaction of ketosteroid isomerase (KSI). Studies of the binding of phenolates to KSI have been taken as proof that the electrostatic preorganization effect only makes a minor contribution to the binding of the real, multiring, transition state (TS). However, our simulation study has determined that the difference between the phenolates and the TS arises from the fact that the nonpolar state of the phenolate can rotate freely relative to the oxyanion hole and thus loses the preorganization contribution. A recent study explored the reactivity of both small and multiring systems and concluded that their similar reactivity contradicts our preorganization idea. Herein, we establish that the available experiments in fact provide what is perhaps the best proof and clarification of the preorganization idea and its crucial role in enzyme catalysis. First, we analyze the binding energy and the pK(a) of equilenin and identify direct experimental evidence for our prediction about the differential electrostatic stabilization of the large TS and the small phenolates. Subsequently, we show that the similar reactivity of the small and large systems is also due to an electrostatic preorganization effect but that this effect only appears in the intermediate state because the TS is not free to rotate. This establishes the electrostatic origin of enzyme catalysis. We also clarify the crucial importance of having a well-defined physical concept when examining catalytic effects and the need for quantitative tools for analyzing such effects.

    If ever there were "charismatic megaflora" of the sea, the Laminariales (kelp) would undoubtedly meet that designation. From the Northeast Pacific kelp forests to the less diverse, but nonetheless dense, kelp beds ranging from the Arctic to the cold temperate waters of the Southern Hemisphere, kelp provide habitat structure and food for a variety of productive marine systems. Consequently, kelp are well represented in the literature, however, understanding their evolution has proven challenging. We used a 152-gene phylogenomics approach to better resolve the phylogeny of the "derived" kelp families (viz., Agaraceae, Alariaceae, Laminariaceae, and Lessoniaceae). The formerly unresolved Egregia menziesii firmly joined a significantly expanded Arthrothamnaceae including Arthrothamnus, Cymathaere, Ecklonia, Macrocystis, Nereocystis, Pelagophycus, Postelsia, Pseudolessonia, Saccharina, and Streptophyllopsis, which rendered both the Laminariaceae and Lessoniaceae monogeneric. A published eight-gene alignment, the most marker-rich prior to this study, was expanded and analyzed to facilitate inclusion of Aureophycus. Although the topology was unchanged at the family level between the transcriptome data set relative to eight-gene analyses, the superior resolving power of the former was clearly established. © 2016 Phycological Society of America.

    Echocardiography requires the integrated application of a broad spectrum of cognitive and practical skills, e.g. diagnostic knowledge (symbolic), image interpretation (visual perception) and handling of the ultrasound probe (sensorimotor). This complex expertise is acquired through extensive practical training guided by a skilled cardiologist that is often incompatible with clinical reality. Especially for beginners, the most critical point during an echocardiographic examination is the steering of the ultrasound probe to navigate between different cardiological standard planes (sensorimotor skill) without loosing orientation. These transitions or "standard trajectories" can roughly be described by specific movement patterns. We propose an enabling system based on an Augmented Reality simulator for two-dimensional echocardiography imitating this apprenticeship [1]-[3]. During a simulated ultrasound examination the system monitors the activities of the trainee and analyzes the motion pattern of the ultrasound probe. The simulator reacts by mapping the motion patterns onto cognitive orientation demands and providing adaptive feedback in the form of context sensitive help (animations). It partly takes the role of the critical teacher.

    The connectivity of sources of pollution in catchments has been well studied and brings concepts such as pollution hotspots and critical source areas. However, consideration of the placement of other structures combating rising pollution impacts has been less considered. One such area that is receiving developing focus is the layout of riparian management and buffer strips. However, there are wider aspects of connectivity and landscape structure that can bring benefits to delivery and in-stream processing of pollution. These include wetlands, forests and the distribution of soils of differing connectivity of organic matter varying in bioavailability. Organic matter is a great modulator of catchment processes from controlling the potential of land use (e.g. constraints of soil organic matter and wetness on agricultural use), to the amount and form of nutrients leached from soils, to controls of dissolved organic matter on in-stream biology that responds to nutrient concentrations. As the fundamental control of ecosystem energy available for many heterotrophic processes it mediates uptake, recycling and speciation of N, P at many stages of the catchment from soils to waters; as such DOM can be considered as a nature-based solution exerting a background level of control on inorganic nutrients. This poster explores the role of different structural aspects of catchments that provide beneficial organic matter inputs to rivers. At the fine scale the lability of riparian soil and leaf litter DOC are considered. At a riparian management scale the local changes in buffer strip soil C and DOC relative to field soils are considered. At the largest scale spatial data are explored for riparian structure, forests, wetlands and soils differing in delivery and forms of C across major Scottish rivers and used as co-variates to explain differences in in-stream processing of nutrients.

    Spinal fusion to the sacrum, especially in the setting of deformity and long constructs, is associated with high complication and pseudarthrosis rates. Transsacral discectomy, fusion, and fixation is a minimally invasive spine surgery technique that provides very rigid fixation. To date, this has been minimally studied in the setting of spinal deformity correction. We determined (1) the fusion rate of long-segment arthrodeses, (2) heath-related quality-of-life (HRQOL) outcomes (VAS pain score, Oswestry Disability Index [ODI], SF-36), and (3) the common complications and their frequency in adult patients with scoliosis undergoing transsacral fixation without supplemental pelvic fixation. Between April 2007 and May 2011, 92 patients had fusion of three or more segments extending to the sacrum for spinal deformity. Transsacral L5-S1 fusion without supplemental pelvic fixation was performed in 56 patients. Of these, 46 with complete data points and a minimum of 2 years of followup (mean, 48 months; range, 24-72 months; 18% of patients lost to followup) were included in this study. Nineteen of the 46 (41%) had fusions extending above the thoracolumbar junction, with one patient having fusion into the proximal thoracic spine (T3-S1). General indications for the use of transsacral fixation were situations where the fusion needed to be extended to the sacrum, such as spondylolisthesis, prior laminectomy, stenosis, oblique take-off, and disc degeneration at L5-S1. Contraindications included anatomic variations in the sacrum, vascular anomalies, prior intrapelvic surgery, and rectal fistulas or abscesses. Fusion rates were assessed by full-length radiographs and CT scanning. HRQOL data, including VAS pain score, ODI, and SF-36 scores, were assessed at all pre- and postoperative visits. Intraoperative and postoperative complications were noted. Forty-one of 46 patients (89%) developed a solid fusion at L5-S1. There were significant improvements in all HRQOL parameters. Eight

    Actions to promote media use for education at all levels in developing countries have to cope with a number of deterrents like the lack of appropriate audiovisual materials and a media support infrastructure. In the early eighties the World Health Organization and United Nations Development Programme initiated a capacity building project to enable developing countries to generate sufficient instructional and learning materials for medical and health education. Since South Africa is still a non-participator in the programme, this article presents the findings of a recent survey to get a global picture of health learning materials support in developing countries as a possible model for South Africa.

    Introduction: There is limited evidence of the benefits of information and communication technology (ICT) to support integrated aged care services. Objectives: We undertook a case study to describe carelink+, a centralised client service management ICT system implemented by a large aged and community care service provider, Uniting. We sought to explicate the care-related information exchange processes associated with carelink+ and identify lessons for organisations attempting to use ICT to support service integration. Methods: Our case study included seventeen interviews and eleven observation sessions with a purposive sample of staff within the organisation. Inductive analysis was used to develop a model of ICT-supported information exchange. Results: Management staff described the integrated care model designed to underpin carelink+. Frontline staff described complex information exchange processes supporting coordination of client services. Mismatches between the data quality and the functions carelink+ was designed to support necessitated the evolution of new work processes associated with the system. Conclusions: There is value in explicitly modelling the work processes that emerge as a consequence of ICT. Continuous evaluation of the match between ICT and work processes will help aged care organisations to achieve higher levels of ICT maturity that support their efforts to provide integrated care to clients.

    The objective of this study was to describe parents' experiences of family functioning, health and social support provided by nursing personnel, while their child was in intensive care, and to determine how social support was associated with family functioning and family health. Cross-sectional study. The data were collected by a self-administered questionnaire from 31 parents of critically ill children from 2010 to 2011. The data were analysed statistically. The parents considered their family functioning, health and social support provided by the nursing personnel to be good. The sub-area of family functioning that rated the lowest was strengths of family, whereas the lowest rated sub-area of family health was ill-being. Child's previous hospital treatments were associated with family health. Parents, whose child had already been in hospital care, reported more well-being and less ill-being than parents with children hospitalised for the first time. Parents' education was associated with family functioning, family health and social support given by the nurses. Weak positive correlation was also found between social support given by nurses and family health experienced by parents. There is a need to discuss how nursing care can further support parental resources. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The Care Provider Support Program (CPSP) was created as a way to improve the resiliency of military health care providers. The purpose of this pilot study was to update what is currently known about the resiliency, coping, and compassion fatigue of military and civilian registered nurses, licensed practical nurses (LPNs), and medics who treat wounded Soldiers and whether these factors can be improved over a sustained period of time. A prospective cohort pilot study was implemented to investigate the long-term effects of CPSP training on military and civilian nurses, LPNs, and medics (n = 93) at an Army Medical Center utilizing the Connor-Davidson Resilience Scale, the Ways of Coping Questionnaire, and Professional Quality of Life Questionnaire. Twenty-eight participants returned follow-up questionnaires. CPSP was significant in reducing burnout as measured by the Professional Quality of Life questionnaire, leading to decreased compassion fatigue. CPSP training did not affect resiliency scores on the Connor-Davidson resilience scale or coping scores as measured by the Ways of Coping Questionnaire. on the basis of the results of this study, CPSP training was effective in reducing burnout, which often leads to decreased compassion fatigue in a group of military and civilian registered nurses, LPNs, and medics.

    Providing cardiopulmonary resuscitation is an essential competency for nurses. Nurse educators involved in staff development and continuing education spend numerous hours offering basic life support courses and conducting performance improvement activities such as mock codes. This study provides evidence that cardiopulmonary resuscitation performance skills using self-directed learning methods are as good as or, on a number of parameters, better than those achieved with a more resource- and time-intensive traditional approach.

    To achieve its goal of producing vehicles that use two thirds less fuel than current vehicles, the Partnership of a New Generation of Vehicles (PNGV) is designing vehicles that will use lightweight materials in place of heavier materials used in current vehicles. using new materials in automobiles will require the development of a supporting infrastructure to produce both the substitute materials and the components of the substitute materials, as well as the automotive parts constructed from the new materials. This report documents a set of analyses that attempt to identify potential barriers--economic, infrastructure, and public acceptance barriers--to the materials substitution in New Generation Vehicles. The analyses rely on hypothetical vehicle market penetration scenarios and material composition. The approach is comprehensive, examining issues ranging from materials availability to their eventual disposition and its effect on the automobile recycling industry, and from supporting industries' capacity to the public acceptability of these vehicles. The analyses focus on two likely substitute materials, aluminum and glass-reinforced polymer composites.

    On a fixed platforms project are not only carried out by a contractor, but two or more contractors. Cooperation in the construction of fixed platforms is often not according to plan, it is caused by several factors. It takes a good synergy between the contractor to avoid miss communication may cause problems on the project. For the example is about support material (sea fastening, skid shoe and shipping support) used in the process of sending a jacket structure to operation place often does not return to the contractor. It needs a systematic method to overcome the problem of support material. This paper analyses the causes and effects of GAS Compressor Platform that support material is not return, using Fault Tree Analysis (FTA) and Event Tree Analysis (ETA). From fault tree analysis, the probability of top event is 0.7783. From event tree analysis diagram, the contractors lose Rp.350.000.000, - to Rp.10.000.000.000, -.

    A new method is proposed to generate text material for assessing maximum reading speed of adult readers. The described procedure allows one to generate a vast number of equivalent short sentences. These sentences can be displayed for different durations in order to determine the reader's maximum speed using a psychophysical threshold algorithm. Each sentence is built so that it is either true or false according to common knowledge. The actual reading is verified by asking the reader to determine the truth value of each sentence. We based our design on the generator described by Crossland et al. and upgraded it. The new generator handles concepts distributed in an ontology, which allows an easy determination of the sentences' truth value and control of lexical and psycholinguistic parameters. In this way many equivalent sentence can be generated and displayed to perform the measurement. Maximum reading speed scores obtained with pseudo-randomly chosen sentences from the generator were strongly correlated with maximum reading speed scores obtained with traditional MNREAD sentences (r = .836). Furthermore, the large number of sentences that can be generated makes it possible to perform repeated measurements, since the possibility of a reader learning individual sentences is eliminated. Researchers interested in within-reader performance variability could use the proposed method for this purpose.

    Domestic violence has been described as a public health epidemic, with victims of domestic violence encountered in all health care settings. Within the United Kingdom the role of the health visitor (specialist community public health nurse) is to promote health in the whole community; every family with a child under five years has a named health visitor. Preparation for the health visitor role is unique to the United Kingdom. Health visitors are particularly well placed to identify and support mothers who are experiencing domestic violence. The objective of this review was to synthesise the best available evidence relating to support provided by UK health visitors for mothers who have experienced domestic violence, from both the mothers and the health visitors' perspectives. The participants of interest were mothers who have experienced domestic violence and health visitors who offer support to those mothers.The self reported experiences of health visitor support provided to mothers who have experienced domestic violence, from the perspective of both the mothers and the health visitors providing the support.This review considered studies that focus on qualitative data including, but not limited to, designs such as ethnography, phenomenology, grounded theory, action research and feminist research. Studies published up to April 2011 were included in the review. The search was restricted to English language studies. The databases searched were: Medline, CINAHL, PsycINFO, PsycARTICLES, EMBASE, British Nursing Index and Archive, ASSIA and TRIP. Studies were assessed for methodological quality using the standardised critical appraisal instruments from the Joanna Briggs Institute. Data were extracted using standardised data extraction tools from the Joanna Briggs Institute. Data synthesis used the Joanna Briggs Institute approach for meta-synthesis by meta-aggregation. Findings were synthesised into categories, which were aggregated into synthesised findings. Four

    The aim of this paper is to provide a review on the usage of different anchoring media (supports) for immobilising commonly employed photocatalysts for degradation of organic pollutants. The immobilisation of nano-sized photocatalysts can eliminate costly and impractical post-treatment recovery of spent photocatalysts in largescale operations. Some commonly employed immobilisation aids such as glass, carbonaceous substances, zeolites, clay and ceramics, polymers, cellulosic materials and metallic agents that have been previously discussed by various research groups have been reviewed. The study revealed that factors such as high durability, ease of availability, low density, chemical inertness and mechanical stability are primary factors responsible for the selection of suitable supports for catalysts. Common techniques for immobilisation namely, dip coating, cold plasma discharge, polymer assisted hydrothermal decomposition, RF magnetron sputtering, photoetching, solvent casting, electrophoretic deposition and spray pyrolysis have been discussed in detail. Finally, some common techniques adopted for the characterisation of the catalyst particles and their uses are also discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2004-04-01

    Fully hydrated stacks of DOPC lipid bilayer membranes generate large diffuse x-ray scattering that corrupts the Bragg peak intensities that are used in conventional biophysical structural analysis, but the diffuse scattering actually contains more information. Using an efficient algorithm for fitting extensive regions of diffuse data to classical smectic liquid crystalline theory we first obtain the compressional modulus B= 10(13) erg/ cm(4), which involves interactions between membranes, and the bending modulus K(c) =8x 10(-13) erg of the membranes. The membrane form factor F ( q(z) ) is then obtained for most values of q(z) up to 0.8 A(-1). The electron density profile rho(z) is obtained by fitting models to F( q(z) ). Constraining the models to conform to other measurements provides structural quantities such as area A=72.1+/-0.5 A(2) per lipid at the interface.

    The trend for terminally ill patients to receive much of their end-of-life care at home necessitates the design of services to facilitate this. Care at home also requires that informal care be provided by family members and friends. This study investigated informal carers' preferences for support services to aid the development of end-of-life health care services. This cross-sectional study used 2 discrete choice experiments to ascertain the preferences of carers supporting patients with different levels of care need, determined by the assistance needed with personal care and labeled High Care (HC) and Low Care (LC). The sample included 168 informal carers of people receiving palliative care at home from 2 palliative care services in Sydney, Australia. Data were collected in face-to-face interviews; carers chose between 2 hypothetical plans of support services and their current services. Data were analyzed with generalized multinomial logit models that were used to calculate the impact of each attribute on the probability of a carer choosing a service plan. Preferred support included nursing services; the probability of choosing a plan increased significantly if it included nurse home visits and phone advice (P situation. The most valued services are those that support carers in their caregiving role; however, supportive care preferences vary with the different circumstances of patients and carers. © The Author(s) 2013.

    The social and institutional environments in which informal healthcare providers operate shape their health and business practices, particularly in contexts where regulatory enforcement is weak. In this study, we adopt a social capital perspective to understanding the social networks on which proprietary and patent medicine vendors (PPMVs) in Nigeria rely for support in the operation of their shops. Data are drawn from 70 in-depth interviews with PPMVs in three states, including interviews with local leaders of the PPMV professional association. We find that PPMVs primarily relied on more senior colleagues and formal healthcare professionals for informational support, including information about new medicines and advice on how to treat specific cases of illness. For instrumental support, including finance, start-up assistance, and intervention with regulatory agencies, PPMVs relied on extended family, the PPMVs with whom they apprenticed, and the leaders of their professional association. PPMVs' networks also provided continual reinforcement of what constitutes good PPMV practice through admonishments to follow scope of practice limitations. These informal reminders, as well as monitoring activities conducted by the professional association, served to reinforce PPMVs' concern with avoiding negative customer health outcomes, which were perceived to be detrimental to their business reputations. That PPMVs' networks both encouraged practices to reduce the likelihood of poor health outcomes, and provided advice regarding customers' health conditions, highlights the potential impact of informal providers' access to different forms of social capital on their delivery of health services, as well as their success as microenterprises.

    Low durability is the major challenge hindering the large-scale implementation of proton exchange membrane fuel cell (PEMFC) technology, and corrosion of carbon support materials of current catalysts is the main cause. Here, we describe the finding of remarkably high durability with the use of a novel support material. This material is based on hollow carbon nanocages developed with a high degree of graphitization and concurrent nitrogen doping for oxidation resistance enhancement, uniform deposition of fine Pt particles, and strong Pt-support interaction. Accelerated degradation testing shows that such designed catalyst possesses a superior electrochemical activity and long-term stability for both hydrogen oxidation and oxygen reduction relative to industry benchmarks of current catalysts. Further testing under conditions of practical fuel cell operation reveals almost no degradation over long-term cycling. Such a catalyst of high activity, particularly, high durability, opens the door for the next-generation PEMFC for “real world” application. PMID:24658614

    Although breast milk has numerous benefits for infants' development, with greater effects in those born preterm (at breastfeeding duration than mothers of term infants. One of the explanations proposed is the difficulties in the transition from a Neonatal Intensive Care Unit (NICU) to the home environment. A person-centred proactive telephone support intervention after discharge from NICU is expected to promote mothers' sense of trust in their own capacity and thereby facilitate breastfeeding. A multicentre randomized controlled trial has been designed to evaluate the effectiveness and cost-effectiveness of person-centred proactive telephone support on breastfeeding outcomes for mothers of preterm infants. Participating mothers will be randomized to either an intervention group or control group. In the intervention group person-centred proactive telephone support will be provided, in which the support team phones the mother daily for up to 14 days after hospital discharge. In the control group, mothers are offered a person-centred reactive support where mothers can phone the breastfeeding support team up to day 14 after hospital discharge. The intervention group will also be offered the same reactive telephone support as the control group. A stratified block randomization will be used; group allocation will be by high or low socioeconomic status and by NICU. Recruitment will be performed continuously until 1116 mothers (I: 558 C: 558) have been included. proportion of mothers exclusively breastfeeding at eight weeks after discharge. proportion of breastfeeding (exclusive, partial, none and method of feeding), mothers satisfaction with breastfeeding, attachment, stress and quality of life in mothers/partners at eight weeks after hospital discharge and at six months postnatal age. Data will be collected by researchers blind to group allocation for the primary outcome. A qualitative evaluation of experiences of receiving/providing the intervention will also be

    When proper protocols are followed, children who are identified with a permanent hearing loss early in life have opportunities to develop language on par with their typical hearing peers. Young children with hearing loss are dependent on their parents to manage intervention during early years critical to their development, and parents' ability to effectively integrate recommendations in daily life is foundational for intervention success. Audiologists and early intervention professionals not only need to provide current evidence-based services, but also must address parents' emotional and learning needs related to their child's hearing loss. This study explored practice patterns related to education and support provided to parents of children with hearing loss and the influence of an in-service training on provider attitudes. This study used a prepost design with a self-report questionnaire to identify practice patterns related to communication skills and support used by providers when working with parents of children with hearing loss. A total of 45 participants (21 professionals and 24 graduate students) currently working with children completed the pretraining questionnaire, and 29 participants (13 professionals and 16 graduate students) completed the postquestionnaire. Data were collected using an online questionnaire before the training and 1 mo after training. Descriptive analyses were done to identify trends, and paired-samples t-tests were used to determine changes pretraining to posttraining. Findings revealed that professionals most frequently teach skills to mothers (91%) and infrequently teach skills to fathers (19%) and other caregivers (10%). Professionals reported frequently collaborating with other intervention providers (76%) and infrequently collaborating with primary care physicians (19%). One-third of the professionals reported addressing symptoms of depression and anxiety as an interfering factor with the ability to implement management

    Industrialization of space and other space activities depend entirely on supply of materials from the Earth. This is a high cost route for materials supply. Space industrialization will require life support systems for maintenance and operation staff and these will of necessity be of a sophisticated nature. Use of raw materials obtained by an unmanned space shuttle, initially, and by manned shuttles later could significantly reduce the cost of life support in space. These raw materials could be obtained from small asteroids and satellites, and would consist of primary nutrients. Future development of such sources is discussed, including food production in automated asteroid-based facilities. The level of technology required is available now, and should become economical within a century.

    To provide an in-depth exploration regarding the Registered Nurse (RN) and Healthcare Chaplains' (HCC) perspective of the role of the family support person (FSP) during family witnessed resuscitation (FWR). A phenomenological approach utilising in-depth interviews were undertaken outside of the work setting. A purposive sample of 4 RN's and 3 HCC were recruited from four sites within the United Kingdom. All interviews were tape recorded, transcribed verbatim and analysed utilising Husserl's framework. Seven key themes emerged which included assessment, managing choice, navigating the setting, on-going commentary, coming to terms with death, conflicts and support. This study has provided an insight regarding the intense clinical engagement associated with the role of the FSP and highlighted the importance of this role for family member's optimal care and support. It is vital that adequate professional development is instigated and that support mechanisms are in place for those health care professionals (HCP) undertaking this role in order to help family members through this difficult experience.

    The prevalence of dementia will continue to increase with the ageing of the population. Many people living with dementia will reach a stage where surrogate decision-makers-mostly family carers-will need to make a range of decisions on their behalf. The aim of this study was to learn from surrogate decision-makers how they can be most effectively supported in this role. The study employed a qualitative design using semi-structured face-to-face or telephone interviews with a purposive sample of 34 surrogate decision-makers of people living with dementia. Transcripts of participant interviews were reviewed using a thematic approach to analysis. Four main themes were identified from this analysis: needing greater community awareness of dementia and its impact; intervening early in cognitive decline; relying on health professionals for ongoing support; and seeking and using support from wherever is relevant for each person. Based on this analysis and a review of the literature, we propose a wholistic set of recommendations for the support of surrogate decision-makers. Healthcare professionals need to help family carers understand the likely trajectory of dementia, including the significance of surrogate decision-making. They can support the person living with dementia and their surrogates to undertake advance care planning and they can act as empathic guides during this process. Health and community care organisations need to provide a "key worker" model wherever possible so that the person living with dementia and their surrogate decision-maker do not have to seek support from multiple staff members or organisations. Carer support programmes can routinely include information and resources about surrogate decision-making. Community and government organisations can help people prepare for the possibility of becoming surrogate decision-makers by promoting a greater public awareness and understanding of both dementia and advance care planning. © 2017 John Wiley & Sons Ltd.

    Excited state proton transfer reactions of 1-naphthylamine (R-NH 2) adsorbed at the surfaces of tungstophosphoric acid supported MCM-41 materials have been studied using steady state fluorescence and picosecond time correlated single photon counting techniques. Evidence for the formation of X* (an adduct between the R-NH 2 and the acid) showed strongly enhanced surface acidity of the supported MCM-41 materials. The excited state lifetime of X* was used to estimate the surface acidity which was found to be between 9.3 and 10.4 M acidic solution depending upon the solvent used in the loading experiment.

    The purpose of this study was to evaluate the effectiveness of supplemental diabetes-related training modalities and volunteer activities in increasing first-year medical students' knowledge/comfort in providing diabetes self-management education and support (DSMES) to patients. A group of medical students developed supplemental diabetes-related training/volunteer programs. The training modalities included an optional 7-session interprofessionally taught Diabetes Enrichment Elective and a 3-hour endocrinologist-led training session intended to prepare students for involvement in an inpatient DSMES volunteer program. The volunteer program provided the students with the opportunity to provide DSMES to patients with diabetes admitted to an academic medical center. Those participating in any of the stated programs were compared to those with no such training regarding confidence in providing DSMES using an optional online survey. The results were analyzed by using Mann-Whitney U test and descriptive analyses. A total of 18 first-year medical students responded to the optional survey with a response rate of ~30% (10 of 33) among participants in any training/volunteer program. First-year medical students who attended any of the offered optional programs had statistically significant higher comfort level in 4 of the 6 areas assessed regarding providing DSMES compared with those with no such training (ptraining modalities/volunteer programs can provide benefit in providing medical students with practical knowledge while improving their confidence in providing DSMES to patients with diabetes.

    Malnutrition is one of the health problems that can be prevented by appropriate nutrition care provided by healthcare providers. However, this practice is still lacking possibly because of the providers' inadequate knowledge. The aim of this study was to evaluate the self-reported knowledge, attitudes, and practices of pharmacists and doctors toward nutrition support in a tertiary care hospital setting. A validated questionnaire was distributed to all the doctors and pharmacists working in a tertiary hospital in Penang, Malaysia. Seven individuals including academics, general surgeons, and pharmacists performed the face and content validity. The questionnaire was piloted using 24 healthcare providers at a different hospital. Of 400 surveyed, 158 doctors and 72 pharmacists from various grades completed the questionnaire. More doctors (31.6%) than pharmacists (15.3%) reported adequate knowledge to perform patients' nutrition screening. However, in the knowledge assessment, pharmacists had a higher mean score (6.07 ± 1.77) than the doctors did (4.59 ± 1.87; P doctors have ambivalent attitudes toward nutrition support. Only 31.3% stated that they perform nutrition screening on admission, and half of them performed nutrition assessment during hospitalization. Inappropriate nutrition care might be due to the lack of guidelines and insufficient knowledge among doctors and pharmacists. Special nutrition training and education for both pharmacists and doctors should be established. © 2014 American Society for Parenteral and Enteral Nutrition.

    Despite over three decades of research linking social support and optimal health outcomes, social support is not systematically assessed or addressed during clinical care. This study sought input from health care providers to inform the design of an intervention intended to facilitate assessment of social support in a way that could aid in anticipatory planning during the process of hospital discharge. Using a purposive sampling strategy, data were collected from providers in two acute care settings serving rural patients, one academic and one community based. Opinions about what an assessment of social support would seek to accomplish, what is currently done and by whom, and the preferred format for delivery were elicited during a series of individual and group interviews. During phase two, feasibility was assessed with three inpatient nurses over 3 clinical days. Field notes were analyzed throughout the project using rapid data analysis techniques. Health care providers endorsed the creation of an assessment and stated that target users would include all members of the discharge team (e.g., clinical nurses, case managers, discharge coordinators, hospitalists, and specialty care). They identified the need for a patient-family resource (vs. a traditional provider-facing assessment). Participants stated that, although both the information collected and the interview process would meet a need to increase patient engagement in inpatient settings, competing clinical demands would require a tool that was easily completed by patients and family and seen as directly informing clinical activities. To this end, although focusing on the eventual development of an electronic tool seemed valuable, a hard-copy resource was considered more feasible for patient use at the present time. The preliminary test of the resulting hard-copy "Going Home Toolkit" demonstrated potential feasibility and usefulness during clinical practice. There is need for not only assessing patients

    Shared, trusted, timely data are essential elements for the cooperation needed to optimize economic, ecologic, and public safety concerns related to water. The Open Water Data Initiative (OWDI) will provide a fully scalable platform that can support a wide variety of data from many diverse providers. Many of these will be larger, well-established, and trusted agencies with a history of providing well-documented, standardized, and archive-ready products. However, some potential partners may be smaller, distributed, and relatively unknown or untested as data providers. The data these partners will provide are valuable and can be used to fill in many data gaps, but can also be variable in quality or supplied in nonstandardized formats. They may also reflect the smaller partners' variable budgets and missions, be intermittent, or of unknown provenance. A challenge for the OWDI will be to convey the quality and the contextual “fitness” of data from providers other than the most trusted brands. This article reviews past and current methods for documenting data quality. Three case studies are provided that describe processes and pathways for effective data-sharing and publication initiatives. They also illustrate how partners may work together to find a metadata reporting threshold that encourages participation while maintaining high data integrity. And lastly, potential governance is proposed that may assist smaller partners with short- and long-term participation in the OWDI.

    Smartphone-based interventions are increasingly used to support self-monitoring, self-management, and treatment and medication compliance in order to improve overall functioning and well-being. In attempting to develop a smartphone application (S-Health) that assists heroin-dependent patients in recovery, a series of focus groups (72 patients, 22 providers) were conducted in China, Taiwan, and the USA to obtain their perspectives on its acceptance and potential adoption. Data were analyzed according to the Diffusion of Innovation (DOI) theory of characteristics important to the adoption of innovation. Important to Relative Advantage, USA participants cited S-Health's potential ability to overcome logistical barriers, while those in China and Taiwan valued its potential to supplement currently limited services. In terms of Compatibility, participants across sites reported recovery needs and goals that such an application could be helpful in supporting; however, its utility during strong craving was questioned in China and Taiwan. Important factors relevant to Complexity included concerns about smartphone access and familiarity, individualization of content, and particularly in China and Taiwan, participants wanted assurance of privacy and security. The study results suggest a general acceptance, but also indicate cultural variations in access to therapeutic and other social support systems, legal repercussions of substance use, societal perceptions of addiction, and the role of family and other social support in recovery. Taking these factors into consideration is likely to increase diffusion as well as effectiveness of these smartphone-based interventions.

    There is a growing body of evidence on the importance of work following a diagnosis of cancer and the need to provide better information, advice and related support to patients on work engagement. The aim of this study was to better understand the nature of those needs and to identify better ways to meet these for those with a urological cancer. The focus was on the issues that were common to three key stakeholder groups. Semi-structured interviews were conducted with stakeholders in North East Scotland: 12 individuals with kidney, bladder or prostate cancer, 10 healthcare providers and 10 managers from large organisations. Five key themes emerged from the Framework Analysis: perceived importance of work engagement; decision-making: treatment, work and cancer; roles and responsibilities; education and training; information, advice and support resources. The data confirmed that work engagement is important to those with urological cancer. It also made clear that the current provision of information and advice could be improved. Any such interventions should involve all three key stakeholder groups with greater clarity on their respective roles and responsibilities. Finally, any new system would be best integrated with existing care provision and supported by adequate education and training of those involved. © 2017 John Wiley & Sons Ltd.

    2011-09-01

    Full Text Available One of the effects of globalization in countries’ education programs is the loss of their native languages. The loss of native languages does not only affect the research work of anthropologists, linguists, and ethnologists; moreover the country’s identity and culture. In this context, our research aims to establish some ethnic contexts which influence students’ learning and to provide dynamic material to support the learning process in an indigenous language. More specifically, in this paper an etnosemiotic approach is presented to create interactive multimedia material for supporting the alphabetization process in the Zapoteca language in the Mexican Region of Oaxaca. This approach is oriented towards elementary schooling and aims to address some current necessities in indigenous education.

    2012-07-01

    Full Text Available In distance education both the physical separation between learner and instructor, and the use of technology create an educational environment that is characterized by learning autonomy and the learner’s active involvement. Because of these, self-regulated learning constitutes an inseparable concept of distance education. This study explores the support and promotion of self-regulated learning in the educational environment of the Hellenic Open University. In particular, this paper examines how the educational material, as it is described in its institutional level of function, supports specific self-regulating strategies of learning in the curriculum provided by the Hellenic Open University. For this purpose, the study is based on literature review of distance education and self-regulated learning. Thus, the cognitive strategies of elobaration and organization, the metacognitive strategies of goal-setting, self-monitoring and self-evaluation, the resourse management strategies of seeking help, seeking information and time management, as well as, the motivation are all included in the self-regulated aspects that are examined. The results of the study indicate that the self-regulated learning is considerably supported and promoted by the printed educational material at the Hellenic Open Univesrity due to its interactive pedagogigal structure. However, it is pointed out that it is possible to maximize the support provided through the improvement of the present structures’ function.

  19. Supported Intrinsically Porous Oligomers as Hybrid Materials for Separations, Storage, and Sensing

    Science.gov (United States)

    Thompson, Anthony Boone

    Adsorption-desorption phenomena are often difficult to study at the molecular level because the surfaces on which they occur can be heterogeneous, giving a wide distribution of adsorption sites and associated energies. Considering that these phenomena underlie an incredibly wide variety of industrially important processes, a better understanding could aid in the development of more efficient methods. In this work, we describe an approach to designing materials with well-defined adsorption sites by covalently attaching intrinsically porous molecules to solid surfaces by a rigid multidentate linker. These cup-shaped molecules are intended to act as adsorption sites on the material, whereas the rigid attachment to the solid support serves to prevent movement and conformational changes of the sites, leading to better understanding of adsorption phenomena. As a proof-of-concept application, materials were used for adsorption of n-butanol biofuel and related compounds from dilute aqueous solution. The materials were thermally and hydrolytically stable, and adsorption phenomena were reversible. Adsorption sites containing more hydrophobic molecular area led to stronger adsorption, suggesting that it is driven by weak van der Waals forces. Likewise, adsorption sites that were strongly polarized performed poorly, possibly reflecting a greater energy penalty of removing water molecules from the cavity. Upon placing a Lewis acidic metal at the bottom of the cavity, an enhancement was seen only with the most acidic metal, which may indicate weak guest coordination. Observing that hydrophobic interactions dominate adsorption on these materials, efforts were made to develop hybrid materials with large hydrophobic area for adsorption. Glaser coupling of diethynylbenzene was used to grow oligo(phenylene butadiynylene)s from the surface of silica, resulting in materials that were more than 25% organic by weight. In addition to their potential use as adsorbents, these materials may

    2012-03-01

    Full Text Available Due to U.S. military Base Realignment and Closure (BRAC efforts and ongoing Overseas Contingency Operations, the number of military servicemembers and veterans seeking civilian-based services has increased. As the military presence grows in previously underrepresented areas, the need for culturally competent providers will also increase both on and off military installations. The purpose of this article is to promote military cultural awareness, while suggesting ways to enhance existing community behavioral health and social support services. It builds on a review of the extant literature and findings from a community assessment to introduce civilian providers to some specific issues affecting servicemembers and their families. A framework describes ways to increase military cultural competence and build community capacity to enhance civilian-based services. In addition, two appendices list some common military terminology and multiple training resources available through military organizations and websites.

  1. HiRadMat at CERN/SPS - A dedicated facility providing high intensity beam pulses to material samples

    CERN Multimedia

    Charitonidis, N; Efthymiopoulos, I

    2014-01-01

    HiRadMat (High Radiation to Materials), constructed in 2011, is a facility at CERN designed to provide high‐intensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies (e.g. vacuum windows, high power beam targets, collimators…) can be tested. The facility uses a 440 GeV proton beam extracted from the CERN SPS with a pulse length of up to 7.2 us, and with a maximum pulse energy of 3.4 MJ (3xE13 proton/pulse). In addition to protons, ion beams with energy of 440 GeV/charge and total pulse energy of 21 kJ can be provided. The beam parameters can be tuned to match the needs of each experiment. HiRadMat is not an irradiation facility where large doses on equipment can be accumulated. It is rather a test area designed to perform single pulse experiments to evaluate the effect of high‐intensity pulsed beams on materials or accelerator component assemblies in a controlled environment. The fa‐ cility is designed for a maximum of 1E16 protons per year, dist...

    2015-01-01

    To assess the effectiveness of computer-aided clinical decision support systems (CDSS) in improving antibiotic prescribing in primary care. A literature search utilizing Medline (via PubMed) and Embase (via Embase) was conducted up to November 2013. Randomized controlled trials (RCTs) and cluster randomized trials (CRTs) that evaluated the effects of CDSS aiming at improving antibiotic prescribing practice in an ambulatory primary care setting were included for review. Two investigators independently extracted data about study design and quality, participant characteristics, interventions, and outcomes. Seven studies (4 CRTs, 3 RCTs) met our inclusion criteria. All studies were performed in the USA. Proportions of eligible patient visits that triggered CDSS use varied substantially between intervention arms of studies (range 2.8-62.8%). Five out of seven trials showed marginal to moderate statistically significant effects of CDSS in improving antibiotic prescribing behavior. CDSS that automatically provided decision support were more likely to improve prescribing practice in contrast to systems that had to be actively initiated by healthcare providers. CDSS show promising effectiveness in improving antibiotic prescribing behavior in primary care. Magnitude of effects compared to no intervention, appeared to be similar to other moderately effective single interventions directed at primary care providers. Additional research is warranted to determine CDSS characteristics crucial to triggering high adoption by providers as a perquisite of clinically relevant improvement of antibiotic prescribing. © The Author 2014.

  3. Nanostructured Carbon Materials as Supports in the Preparation of Direct Methanol Fuel Cell Electrocatalysts

    Directory of Open Access Journals (Sweden)

    María Jesús Lázaro

    2013-08-01

    Full Text Available Different advanced nanostructured carbon materials, such as carbon nanocoils, carbon nanofibers, graphitized ordered mesoporous carbons and carbon xerogels, presenting interesting features such as high electrical conductivity and extensively developed porous structure were synthesized and used as supports in the preparation of electrocatalysts for direct methanol fuel cells (DMFCs. The main advantage of these supports is that their physical properties and surface chemistry can be tailored to adapt the carbonaceous material to the catalytic requirements. Moreover, all of them present a highly mesoporous structure, diminishing diffusion problems, and both graphitic character and surface area can be conveniently modified. In the present work, the influence of the particular features of each material on the catalytic activity and stability was analyzed. Results have been compared with those obtained for commercial catalysts supported on Vulcan XC-72R, Pt/C and PtRu/C (ETEK. Both a highly ordered graphitic and mesopore-enriched structure of these advanced nanostructured materials resulted in an improved electrochemical performance in comparison to the commercial catalysts assayed, both towards CO and alcohol oxidation.

  4. Support and services provided by public health regional surveillance teams to Local Health Departments in North Carolina.

    2011-01-01

    Since 2001, many states have created regional structures in an effort to better coordinate/public health preparedness and response efforts, consolidate services, and supplement local government capacity. While several studies have identified specific benefits to regionalization, including enhanced networking, coordination, and communication, little research has examined the effect of regionalization on specific preparedness and response activities. To better understand the impact of regionalizing public health workforce assets in North Carolina, a survey aimed at documenting specific support and services that Public Health Regional Surveillance Teams(PHRSTs) provide to local health departments (LHDs) was developed and administered by the North Carolina Preparedness and Emergency Response Research Center, located at the North Carolina Institute for Public Health. Of80 potential types of assistance, 26 (33%) were received by 75% or more LHDs, including 9 related to communication and 7 related to exercises. There was significant variation by PHRST region in both the quantity and quality of support and services reported by LHDs. This variation could not be explained by county- or LHD-level variables. PHRST assistance to LHDs is largely focused on communication and liaison activities, regional exercises, and planning. On the basis of these findings, regionalization may provide North Carolina with benefits consistent with those found in other studies such as improved networking and coordination. However, further research is needed to identify whether regional variation is the result of varying capacity or priorities of the PHRSTs or LHDs and to determine how much variation is acceptable.

    2009-01-01

    This paper discusses the effort in evaluating and selecting a light weight impact protection material for the Constellation Space Suit Element (CSSE) Portable Life Support Subsystem (PLSS) conceptual packaging study. A light weight material capable of holding and protecting the components inside the PLSS is required to demonstrate the viability of the flexible PLSS packaging concept. The material needs to distribute, dissipate, and absorb the impact energy of the PLSS falling on the lunar surface. It must also be very robust and function in the extreme lunar thermal vacuum environment for up to one hundred Extravehicular Activity (EVA) missions. This paper documents the performance requirements for selecting a foam protection material, and the methodologies for evaluating commercial off-the-shelf (COTS) foam protection materials. It also presents the materials properties test results and impact drop test results of the various foam materials evaluated in the study. The findings from this study suggest that a foam based flexible protection system is a viable solution for PLSS packaging. However, additional works are needed to optimize COTS foam properties or to develop a composite foam system that will meet all the performance requirements for the CSSE PLSS flexible packaging.

  6. Community, intervention and provider support influences on implementation: reflections from a South African illustration of safety, peace and health promotion

    Science.gov (United States)

    2014-01-01

    Background The development, implementation and evaluation of community interventions are important for reducing child violence and injuries in low- to middle-income contexts, with successful implementation critical to effective intervention outcomes. The assessment of implementation processes is required to identify the factors that influence effective implementation. This article draws on a child safety, peace and health initiative to examine key factors that enabled or hindered its implementation, in a context characterised by limited resources. Methods A case study approach was employed. The research team was made up of six researchers and intervention coordinators, who led the development and implementation of the Ukuphepha Child Study in South Africa, and who are also the authors of this article. The study used author observations, reflections and discussions of the factors perceived to influence the implementation of the intervention. The authors engaged in an in-depth and iterative dialogic process aimed at abstracting the experiences of the intervention, with a recursive cycle of reflection and dialogue. Data were analysed utilising inductive content analysis, and categorised using classification frameworks for understanding implementation. Results The study highlights key factors that enabled or hindered implementation. These included the community context and concomitant community engagement processes; intervention compatibility and adaptability issues; community service provider perceptions of intervention relevance and expectations; and the intervention support system, characterised by training and mentorship support. Conclusions This evaluation illustrated the complexity of intervention implementation. The study approach sought to support intervention fidelity by fostering and maintaining community endorsement and support, a prerequisite for the unfolding implementation of the intervention.

    Smartphone applications can potentially provide recovery monitoring and support in real-time, real-life contexts. Study aims included determining feasibility of (a) adolescents completing ecological momentary assessments (EMAs) and utilizing phone-based ecological momentary interventions (EMIs); and (b) using EMA and EMI data to predict substance use in the subsequent week. Twenty-nine adolescents were recruited at discharge from residential treatment, regardless of their discharge status or length of stay. During the 6-week pilot, youth were prompted to complete an EMA at 6 random times per day and were provided access to a suite of recovery support EMI. Youth completed 87% of the 5580 EMAs. Based on use in the next 7 days, EMA observations were classified into 3 risk groups: "Current Use" in the past 30 minutes (3% of observations), "Unrecognized Risk" (42%), or "Recognized Risk" (55%). All youth had observations in 2 or more risk groups and 38% in all 3. Youth accessed an EMI on average 162 times each week. Participants were 31% female, 48% African American, 21% Caucasian, 7% Hispanic, and 24% Mixed/Other; average age was 16.6 years. During the 90 days prior to entering treatment, youth reported using alcohol (38%), marijuana (41%), and other drugs (7%). When compared with the "Recognized Risk" group's use in the following week (31%), both the "Unrecognized Risk" (50%, odds ratio [OR]=2.08) and "Current Use" (96%, OR=50.30) groups reported significantly higher rates of use in the next week. When an EMI was accessed 2 or more times within the hour following an EMA, the rate of using during the next week was significantly lower than when EMIs were not accessed (32% vs. 43%, OR=0.62). Results demonstrate the feasibility of using smartphones for recovery monitoring and support with adolescents, with potential to reduce use.

    Full Text Available In this article, the authors defined the procedure for maintaining the material and technical base of medical centers providing high-tech assistance (especially, transplant care to Russian citizens. The current regulatory and methodological base determining the procedure for repairs of fixed assets is evaluated, the main issues of capital repair planning in budgetary medical centers providing high-tech medical care are considered. The innovations introduced at the present time into the legislation determining the procedure for capital repairs are defined; the applicable concepts and scope of regulation are disclosed; the procedure for the implementation of major repairs in accordance with the current regulations is considered; the key issues that make it difficult to start capital repairs of the premises in budgetary medical centers providing high-tech medical care to Russian citizens are identified. Administrative and financial discipline while ensuring the working conditions of the material and technical base has been strengthened. Considerable attention should be paid to the medium-term planning of works, preparation of technical documentation, and procurement of funds for preparatory works. Whereas it is necessary to coordinate such decisions with the Ministry of Healthcare of Russia and other governmental institutions in Russia the timing of the implementation of such projects has significantly increased.

    Full Text Available The retrospective analysis of the results of activities at the level of industrial sector of the Russian economy in general and at the level of certain subjects of economy - the enterprise of construction materials and products is completed in the article. According to the analysis results the insufficient efficiency of the use of cumulative resource capacity of the enterprises is proved and the need of the development of complex tools of resource providing management, to which the priority attention is caused by the crisis of economy requiring taking measures to diversification of a range of construction materials and products of the construction offered by the enterprise for the markets, is determined. In the core of the offered tools of management there are approaches of “ramp-up” of the management directed to the maximum concentration of resources of the enterprise in case of new products launch for the construction industry. Three options of financing of production, based on the choice of a ratio of loan and own sources of means are considered. Some conditions of macroeconomic nature, which are important for effective development of the enterprises involved in production of construction materials and products are determined in the conclusion.

    Structural complexity, a form of habitat heterogeneity, influences the structure and function of ecological communities, generally supporting increased species density, richness, and diversity. Recent research, however, suggests the most complex habitats may not harbor the highest density of individuals and number of species, especially in areas with elevated human influence. Understanding nuances in relationships between habitat heterogeneity and ecological communities is warranted to guide habitat-focused conservation and management efforts. We conducted fish and structural habitat surveys of thirty warm-temperate reefs on the southeastern US continental shelf to quantify how structural complexity influences fish communities. We found that intermediate complexity maximizes fish abundance on natural and artificial reefs, as well as species richness on natural reefs, challenging the current paradigm that abundance and other fish community metrics increase with increasing complexity. Naturally occurring rocky reefs of flat and complex morphologies supported equivalent abundance, biomass, species richness, and community composition of fishes. For flat and complex morphologies of rocky reefs to receive equal consideration as essential fish habitat (EFH), special attention should be given to detecting pavement type rocky reefs because their ephemeral nature makes them difficult to detect with typical seafloor mapping methods. Artificial reefs of intermediate complexity also maximized fish abundance, but human-made structures composed of low-lying concrete and metal ships differed in community types, with less complex, concrete structures supporting lower numbers of fishes classified largely as demersal species and metal ships protruding into the water column harboring higher numbers of fishes, including more pelagic species. Results of this study are essential to the process of evaluating habitat function provided by different types and shapes of reefs on the seafloor

We found that intermediate complexity maximizes fish abundance on natural and artificial reefs, as well as species richness on natural reefs, challenging the current paradigm that abundance and other fish community metrics increase with increasing complexity. Naturally occurring rocky reefs of flat and complex morphologies supported equivalent abundance, biomass, species richness, and community composition of fishes. For flat and complex morphologies of rocky reefs to receive equal consideration as essential fish habitat (EFH, special attention should be given to detecting pavement type rocky reefs because their ephemeral nature makes them difficult to detect with typical seafloor mapping methods. Artificial reefs of intermediate complexity also maximized fish abundance, but human-made structures composed of low-lying concrete and metal ships differed in community types, with less complex, concrete structures supporting lower numbers of fishes classified largely as demersal species and metal ships protruding into the water column harboring higher numbers of fishes, including more pelagic species. Results of this study are essential to the process of evaluating habitat function provided by different types and shapes of

    Full Text Available The purpose of the study was to examine opinions of artists in music about state supports for students talented in music. Participants had state sup-ports in music when they were young. A phenomenological study was undertaken to interview the participants. They were interviewed face to face. Data was coded and content-analyzed and categorized by themes. The findings showed that all of the participants expressed that policies related to the education of gifted children in the field of arts in Turkey did not work anymore, losing functionality and effects and special services to be provided for artistically gifted students depended upon individuals who were in charge, showing that the policies were no longer useful. In addition, the participants stated that policies and practices have changed constantly as a result of changes in perceptions of educational politics and decision makers. Therefore, it is reasonable to claim that the greatest challenge in the education of students highly talented in the arts is the lack of a consistent and sustainable national policy

    2014-01-01

    This article is part of the Focus Theme of Methods of Information in Medicine on "Using Data from Ambient Assisted Living and Smart Homes in Electronic Health Records". Concepts of Ambient Assisted Living (AAL) support a long-term health monitoring and further medical and other services for multi-morbid patients with chronic diseases. In Germany many AAL and telemedical applications exist. Synergy effects by common agreements for essential application components and standards are not achieved. It is necessary to define a communication architecture which is based on common definitions of communication scenarios, application components and communication standards. The development of a communication architecture requires different steps. To gain a reference model for the problem area different AAL and telemedicine projects were compared and relevant data elements were generalized. The derived reference model defines standardized communication links. As a result the authors present an approach towards a reference architecture for AAL-communication. The focus of the architecture lays on the communication layer. The necessary application components are identified and a communication based on standards and their extensions is highlighted. The exchange of patient individual events supported by an event classification model, raw and aggregated data from the personal home area over a telemedicine center to health care providers is possible.

    With over 1 million certified physicians in more than 50 countries worldwide, the Advanced Trauma Life Support (ATLS) concept is one of the most successful international education programs. The concept is simple, priority-orientated (ABCDE scheme) and assesses the situation of the trauma patient on the basis of vital signs to treat the life-threatening injuries immediately. With over 100 ATLS provider courses and 10 instruction courses accomplished in less than 6 years, no other land in the world has successfully established this concept in such a short time as Germany. Meanwhile nearly 1,600 colleagues have been trained and certified. Evaluation of the first 100 ATLS courses in Germany supports this concept. The total evaluation of all courses is 1.36 (1.06-1.8, n=100). The individual parts of the course were marked as followed: presentations 1.6 (1.0-2.81, n=100), practical skills stations 1.46 (1.0-2.4, n=100) and surgical skills stations 1.38 (1.0-2.38, n=100). In 2009 a total of 47 ATLS courses were accomplished which will clearly increase in 2010. Other ATLS formats, such as ATCN (Advanced Trauma Care for Nurses) and refresher courses are planned for the beginning of 2010.

    The aim of the current exploratory study was to investigate the impact on care home staff when working with people with dementia at the end of life and to explore how they cope with this aspect of their work. With UK policy encouraging death in the place of residence, rather than hospital, more people with dementia are dying in care homes. A qualitative approach was employed; 20 care home staff working in five English care homes were interviewed. Thematic Analysis was used to analyse the data. Care home staff found the external demands on them and difficulties associated with interacting with people with dementia sometimes challenging, stressful and anxiety-provoking, particularly as residents approached end of life. Emotional aspects of caring for dying residents were sometimes heightened by close attachments with residents and their families. Staff were able to recognise these unmet needs and identified a need for further training and emotional support to manage these stressors. This study revealed rich and complex understandings of the practice dimensions of caring for people with dementia at the end of life and the impact these have on staff. There is a need to develop effective psychosocial interventions that focus on emotional support for care home staff. There will be challenges in providing this in employment settings that are generally low paid, low status, have high turnover and are reliant on temporary or migrant staff, where training is not rewarded, mandatory or culturally valued.

    2015-12-01

    Full Text Available Material selection is a delicate process, typically hinged on a number of factors which can be either cost or environmental related. This process becomes more complicated when designers are faced with several material options of building elements and each option can be supplied by different suppliers whose selection criteria may affect the budgetary and environmental requirements of the project. This paper presents the development of a decision support system based on the integration of building information models, a modified harmony search algorithm and supplier performance rating. The system is capable of producing the cost and environmental implications of different material combinations or building designs. A case study is presented to illustrate the functionality of the developed system.

  4. Materialism.

    Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person's mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization and supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, and emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

    Nuclear material inventories are increasingly being transferred to interim storage locations where they may reside for extended periods of time. Use of a shipping package to store nuclear materials after the transfer has become more common for a variety of reasons. Shipping packages are robust and have a qualified pedigree for performance in normal operation and accident conditions but are only certified over an approved transportation window. The continued use of shipping packages to contain nuclear material during interim storage will result in reduced overall costs and reduced exposure to workers. However, the shipping package materials of construction must maintain integrity as specified by the safety basis of the storage facility throughout the storage period, which is typically well beyond the certified transportation window. In many ways, the certification processes required for interim storage of nuclear materials in shipping packages is similar to life extension programs required for dry cask storage systems for commercial nuclear fuels. The storage of spent nuclear fuel in dry cask storage systems is federally-regulated, and over 1500 individual dry casks have been in successful service up to 20 years in the US. The uncertainty in final disposition will likely require extended storage of this fuel well beyond initial license periods and perhaps multiple re-licenses may be needed. Thus, both the shipping packages and the dry cask storage systems require materials integrity assessments and assurance of continued satisfactory materials performance over times not considered in the original evaluation processes. Test programs for the shipping packages have been established to obtain aging data on materials of construction to demonstrate continued system integrity. The collective data may be coupled with similar data for the dry cask storage systems and used to support extending the service life of shipping packages in both transportation and storage.

    2014-06-01

    Reliable methods of fixation of soft tissue and bone are of utmost importance in reconstructive shoulder surgery and in many orthopaedic applications. Current methods of securing lesser tuberosity osteotomies performed during shoulder arthroplasty and tuberosity fixation performed during repair of proximal humeral fractures often rely on alternating half hitches or surgeon's knots regardless of the suture configuration used passing through the tissue (eg, Mason-Allen, Krackow). The racking hitch knot in contrast to half hitches allows sequential tightening, even under tension, with minimal risk of knot slippage or premature locking. These knot characteristics allow the surgeon to stepwise improve their reduction before committing and locking a construct, preventing hanging knots or under-tensioned repairs. However, little data exist to support the use the racking hitch knot to guide decision making regarding how to back up the knot or to explain the effect of suture material on security and strength. The objectives of our study were (1) to identify the optimal number of half hitches necessary to maintain knot security for a single knot; (2) to evaluate if a difference exists in the relative behavior of racking hitch knots when tied using different suture materials; and (3) to define the biomechanical differences between the racking hitch and two other knot configurations commonly used in shoulder surgery (Weston and square knots). Using an Instron device we tested the effect of adding supplemental half hitches (from one to four) to the racking hitch. Additionally, a selection of commercially available braided nonabsorbable polyethylene sutures and different knot configurations (racking hitch, Weston knot, and square knot) also were tested. Data were compared using ANOVA. Increasing the number of half hitches improved knot performance in peak load testing and cyclic testing, revealing a significant difference between the racking hitch supplemented with one and four

    Successful spaceflight operations require onboard power management systems that reliably achieve mission objectives for a minimal launch weight. Because of their high specific energies and potential for reduced maintenance and logistics, composite flywheels are an attractive alternative to electrochemical batteries. The Rotor Durability Team, which comprises members from the Ohio Aerospace Institute (OAI) and the NASA Glenn Research Center, completed a program of elevated temperature testing at Glenn' s Life Prediction Branch's Fatigue Laboratory. The experiments provided unique design data essential to the safety and durability of flywheel energy storage systems for the International Space Station and other manned spaceflight applications. Analysis of the experimental data (ref. 1) demonstrated that the compressive stress relaxation of composite flywheel rotor material is significantly greater than the commonly available tensile stress relaxation data. Durability analysis of compression preloaded flywheel rotors is required for accurate safe-life predictions for use in the International Space Station.

  10. Inorganic Materials as Supports for Covalent Enzyme Immobilization: Methods and Mechanisms

    Directory of Open Access Journals (Sweden)

    Paolo Zucca

    2014-09-01

    Full Text Available Several inorganic materials are potentially suitable for enzymatic covalent immobilization, by means of several different techniques. Such materials must meet stringent criteria to be suitable as solid matrices: complete insolubility in water, reasonable mechanical strength and chemical resistance under the operational conditions, the capability to form manageable particles with high surface area, reactivity towards derivatizing/functionalizing agents. Non-specific protein adsorption should be always considered when planning covalent immobilization on inorganic solids. A huge mass of experimental work has shown that silica, silicates, borosilicates and aluminosilicates, alumina, titania, and other oxides, are the materials of choice when attempting enzyme immobilizations on inorganic supports. More recently, some forms of elemental carbon, silicon, and certain metals have been also proposed for certain applications. With regard to the derivatization/functionalization techniques, the use of organosilanes through silanization is undoubtedly the most studied and the most applied, although inorganic bridge formation and acylation with selected acyl halides have been deeply studied. In the present article, the most common inorganic supports for covalent immobilization of the enzymes are reviewed, with particular focus on their advantages and disadvantages in terms of enzyme loadings, operational stability, undesired adsorption, and costs. Mechanisms and methods for covalent immobilization are also discussed, focusing on the most widespread activating approaches (such as glutaraldehyde, cyanogen bromide, divinylsulfone, carbodiimides, carbonyldiimidazole, sulfonyl chlorides, chlorocarbonates, N-hydroxysuccinimides.

    The ability of Trametes versicolor ATCC 20869 to colonize several natural and synthetic materials (wheat straw, jute, hemp, maple woodchips, and nylon and polyethylene teraphthalate fibers) and to subsequently decolorize amaranth was evaluated. Jute was found to be the best support material as T. versicolor grew well on it without color leaching from the support and without loss of the jute's integrity over a 4 week period. The fungus immobilized on jute, straw and hemp decolorized amaranth (50 mg l(-1)) at a rate of about 5 mg l(-1) h(-1) without glucose being added. When 1 g l(-1) glucose was added, the dye was degraded more quickly (about 8 mg l(-1) h(-1)). Decoloration did not occur in a suspension culture without glucose. As the number of decoloration cycles increased, the rate of decoloration decreased. This rate was restored to its original level after the biomass was incubated in fresh growth medium for 5 days. With all immobilization supports, the toxicity of the medium before and after decoloration was the same or lower.

    The focus of this work is inspecting the synthesis and comparison of the activities of a catalyst supported on two silicate materials in the epoxidation of 1-octene. The two new catalyst materials were characterized by infrared spectroscopy, elemental analysis, solid-state {sup 29}Si and {sup 13}C nuclear magnetic resonance, scanning electronic microscope (SEM) and analysis of nitrogen. Lastly, the two new catalysts, Silsesq-TCA-[(W(CO){sub 3}I{sub 2}){sub 3}] and Silica-TCA-[W(CO){sub 3}I{sub 2}] were tested as catalysts in reactions of epoxidation of 1-octene and compared with their analogue not supported [W(CO){sub 3}I{sub 2}(thiocarbamide)]. After an extensive literature search, we verified that our work is the first that has reported the immobilization process of [W(CO){sub 3}I{sub 2}(NCCH{sub 3}){sub 2}] on silsesquioxane and silica gel functionalized with propyl-thiocarbamide groups and their applications as catalysts of reactions of catalytic epoxidation of 1-octene. - Highlights: • Immobilization of [W(CO){sub 3}I{sub 2}(NCCH{sub 3}){sub 2}] complex onto mesoporous supports. • Synthesis and characterization of new mesoporous catalysts. • The new catalysts exhibit great catalytic activity in the epoxidation of 1-octene. • Recyclable catalysts with excellent reusability and stability.

    2012-07-01

    Full Text Available The analyses of genome sequences have led to the proposal that lateral gene transfers (LGTs among prokaryotes are so widespread that they disguise the interrelationships among these organisms. This has led to questioning whether the Darwinian model of evolution is applicable to the prokaryotic organisms. In this review, we discuss the usefulness of taxon-specific molecular markers such as conserved signature indels (CSIs and conserved signature proteins (CSPs for understanding the evolutionary relationships among prokaryotes and to assess the influence of LGTs on prokaryotic evolution. The analyses of genomic sequences have identified large numbers of CSIs and CSPs that are unique properties of different groups of prokaryotes ranging from phylum to genus levels. The species distribution patterns of these molecular signatures strongly support a tree-like vertical inheritance of the genes containing these molecular signatures that is consistent with phylogenetic trees. Recent detailed studies in this regard on Thermotogae and Archaea, which are reviewed here, have identified large numbers of CSIs and CSPs that are specific for the species from these two taxa and a number of their major clades. The genetic changes responsible for these CSIs (and CSPs initially likely occurred in the common ancestors of these taxa and then vertically transferred to various descendants. Although some CSIs and CSPs in unrelated groups of prokaryotes were identified, their small numbers and random occurrence has no apparent influence on the consistent tree-like branching pattern emerging from other markers. These results provide evidence that although LGT is an important evolutionary force, it does not mask the tree-like branching pattern of prokaryotes or understanding of their evolutionary relationships. The identified CSIs and CSPs also provide novel and highly specific means for identification of different groups of microbes and for taxonomical and biochemical

    Dying at home is the preference of many patients with life-limiting illness. This is often not achieved and a key factor is the availability of willing and able family carers. To elicit family carers' views about the community support that made death at home possible. Qualitative study in East Devon, North Lancashire, and Cumbria. Participants were bereaved family carers who had provided care at the end of life for patients dying at home. Semi-structured interviews were conducted 6-24 months after the death. Fifty-nine bereaved family carers were interviewed (54% response rate; 69% female). Two-thirds of the patients died from cancer with median time of home care being 5 months and for non-cancer patients the median time for home care was 30 months. An overarching theme was of continuity of care that divided into personal, organisational, and informational continuity. Large numbers and changes in care staff diluted personal continuity and failure of the GPs to visit was viewed negatively. Family carers had low expectations of informational continuity, finding information often did not transfer between secondary and primary care and other care agencies. Organisational continuity when present provided comfort and reassurance, and a sense of control. The requirement for continuity in delivering complex end-of-life care has long been acknowledged. Family carers in this study suggested that minimising the number of carers involved in care, increasing or ensuring personal continuity, and maximising the informational and organisational aspects of care could lead to a more positive experience. © British Journal of General Practice 2014.

    Highlights: • Surface modification with fibronectin, heparin and VEGF could selectively anticoagulant and promote endothelialization. • The bioactivity of biomolecules was more efficiently maintained via specific intermolecular interaction. • Poly-l-lysine interlayer was more feasible and the degradation product had no harm to human body. - Abstract: The biocompatibility of currently used coronary artery stent is still far from perfect, which closely related to insufficient endothelialization and thrombus formation. In this study, heparin, fibronectin and VEGF were immobilized on Ti surface to construct a multifunctional microenvironment with favorable properties to inhibit thrombosis formation and promote endothelialization simultaneously. The microenvironment on Ti surface was characterized in detail and demonstrated that the Hep/Fn/VEGF biofunctional coating was constructed successfully on Ti surface. The influence of surface properties such as chemical composition, roughness, hydrophilicity, and binding density of biomolecules on the performances of hemocompatibility and cytocompatibility was evaluated and discussed. Modified surface significantly enhanced the AT III binding density and prolonged the clotting time. In vitro platelet adhesion and activation assays further proved that the modified surface presented favorable anti-coagulant property. In addition, the proliferation of endothelial progenitor cells (EPCs) and endothelial cells (ECs) on the Hep/Fn/VEGF biofunctional coating was significantly promoted. In conclusion, the Hep/Fn/VEGF biofunctional coating was successfully constructed with desirable anticoagulant and endothelialization supporting properties. This work may provide a promising approach for biofunctional surface modification of coronary artery stent to acquire a desired multifunctional microenvironment.

    Background Harm reduction is a health-centred approach that seeks to reduce the health and social harms associated with high-risk behaviors, such as illicit drug use. The objective of this study is to determine the association between the beliefs of a group of adult, male prisoners in Iran about the transmission of HIV and their high-risk practices while in prison. Methods A cross-sectional study was conducted in 2004. The study population was a random selection of 100 men incarcerated at Rajaei-Shahr prison. The data were collected through a self-administered questionnaire. Focus group discussions were held at the prison to guide the design of the questionnaire. The relationship between components of the Health Belief Model (HBM) and prisoners' risky HIV-related behaviors was examined. Results Calculating Pearson's correlation coefficient, a significant, positive association was found between the benefit component of the HBM and prisoners not engaging in HIV high-risk behaviors. Conclusion Educational harm reduction initiatives that promote the effectiveness of strategies designed to reduce the risk of HIV transmission may decrease prisoners' high-risk behaviors. This finding provides initial support for the Iran prison system's current offering of HIV/AIDS harm reduction programming and suggests the need to offer increased education about the effectiveness of HIV prevention practices.

    Adverse drug events (ADEs) are a major cause of morbidity in hospitalised and ambulatory patients. Computerised provider order entry (CPOE) combined with clinical decision support systems (CDSS) are being widely implemented with the goal of preventing ADEs, but the effectiveness of these systems remains unclear. We searched the specialised database Agency for Healthcare Research and Quality (AHRQ) Patient Safety Net to identify reviews of the effect of CPOE combined with CDSS on ADE rates in inpatient and outpatient settings. We included systematic and narrative reviews published since 2008 and controlled clinical trials published since 2012. We included five systematic reviews, one narrative review and two controlled trials. The existing literature consists mostly of studies of homegrown systems conducted in the inpatient setting. CPOE+CDSS was consistently reported to reduce prescribing errors, but does not appear to prevent clinical ADEs in either the inpatient or outpatient setting. Implementation of CPOE+CDSS profoundly changes staff workflow, and often leads to unintended consequences and new safety issues (such as alert fatigue) which limit the system's safety effects. CPOE+CDSS does not appear to reliably prevent clinical ADEs. Despite more widespread implementation over the past decade, it remains a work in progress. Published by the BMJ Publishing Group Limited.

    Full Text Available Abstract Background The goal of this study is to extend research on evidence-based practice (EBP implementation by examining the impact of organizational type (public versus private and organizational support for EBP on provider attitudes toward EBP and EBP use. Both organization theory and theory of innovation uptake and individual adoption of EBP guide the approach and analyses in this study. We anticipated that private sector organizations would provide greater levels of organizational support for EBPs leading to more positive provider attitudes towards EBPs and EBP use. We also expected attitudes toward EBPs to mediate the association of organizational support and EBP use. Methods Participants were mental health service providers from 17 communities in 16 states in the United States (n = 170. Path analyses were conducted to compare three theoretical models of the impact of organization type on organizational support for EBP and of organizational support on provider attitudes toward EBP and EBP use. Results Consistent with our predictions, private agencies provided greater support for EBP implementation, and staff working for private agencies reported more positive attitudes toward adopting EBPs. Organizational support for EBP partially mediated the association of organization type on provider attitudes toward EBP. Organizational support was significantly positively associated with attitudes toward EBP and EBP use in practice. Conclusion This study offers further support for the importance of organizational context as an influence on organizational support for EBP and provider attitudes toward adopting EBP. The study demonstrates the role organizational support in provider use of EBP in practice. This study also suggests that organizational support for innovation is a malleable factor in supporting use of EBP. Greater attention should be paid to organizational influences that can facilitate the dissemination and implementation of EBPs in

    Freeze-dried delignified cellulosic (DC) material supported biocatalyst is proposed as a suitable form of biocatalyst to be preserved. The alcoholic fermentation of glucose using freeze-dried immobilized cells is reported. Freeze-dried immobilized baker's yeast cells on DC material do not need any protective medium during freeze-drying. The effect of initial glucose concentration and temperature on the alcoholic fermentation kinetic parameters is reported in the present study. It was found that the freeze-dried immobilized cells ferment more quickly than free freeze-dried cells and have a lower fermentation rate as compared with wet immobilized cells. However, repeated batch fermentations showed freeze-dried immobilized cells to ferment at about the same fermentation rate as wet immobilized cells. The results indicate that the freeze-dried immobilized cells must be further studied to establish a process for the preservation of immobilized cells.

  2. International survey of research university leadership views on supporting open access scholarly & educational materials

    This report looks closely at the attitudes on open access of a sample of 314 deans, chancellors, department chairmen, research institute directors, provosts, trustees, vice presidents and other upper level administrators from more than 50 research universities in the USA, Canada, the UK, Ireland and Australia. The report gives detailed information on what they think of the cost of academic journal subscriptions, and how they understand the meaning of the term “open access.” The study also gives highly detailed data on what kind of policies the research university elite support or might support in the area of open access, including policies such as restricting purchases of very high-priced journals, paying publication fees for open access publications, mandating deposit of university scholarship into digital repositories, and developing open access educational materials from university resources. Just a few of the report’s many findings are that: • The lowest percentage of those interviewed considering...

    The Partnership for a New Generation of Vehicles (PNGV) program intends to develop new designs for automobiles that will reduce fuel consumption by two thirds but otherwise have price, comfort, safety, and other measures of performance similar to the typical automobile now on the market. PNGV vehicle designs are expected to substitute lightweight materials, such as aluminum, magnesium, carbon-reinforced polymer composites, glass-reinforced polymer composites, and ultra- light steel, for heavier materials such as steel and iron in automobile components. The target mass of a PNGV vehicle is 1,960 pounds, as compared to the average current vehicle that weights 3,240 pounds. Other changes could include the use of different ferrous alloys, engineering changes, or incorporation of advanced ceramic components. Widespread adoption of these vehicle designs would affect materials markets and require concurrent development and adoption of supporting technologies to supply the materials and to use and maintain them in automobiles. This report identifies what would be required to bring about these changes and developments in materials substitution; identifies reasons that might make these substitutions difficult to accomplish within the overall objectives and timetable of the PNGV program; and identifies any issues arising from the substitution that could prompt consideration of policies to deal with them. The analysis in this paper uses scenarios that assume the production of new generation vehicles will begin in 2007 and that their market share will increase gradually over the following 25 years. The scenarios on which the analysis is based assume a maximum substitution of each potential replacement material considered. This maximum substitution of individual materials (i.e., the amount of replacement material by weight that would be added to the baseline vehicle`s composition) is as follows: ULSAB (high strength steel), 298 lbs.; glass-reinforced composites, 653 lbs.; carbon

  6. Predator diversity and abundance provide little support for the enemies hypothesis in forests of high tree diversity.

    Andreas Schuldt

    Full Text Available Predatory arthropods can exert strong top-down control on ecosystem functions. However, despite extensive theory and experimental manipulations of predator diversity, our knowledge about relationships between plant and predator diversity--and thus information on the relevance of experimental findings--for species-rich, natural ecosystems is limited. We studied activity abundance and species richness of epigeic spiders in a highly diverse forest ecosystem in subtropical China across 27 forest stands which formed a gradient in tree diversity of 25-69 species per plot. The enemies hypothesis predicts higher predator abundance and diversity, and concomitantly more effective top-down control of food webs, with increasing plant diversity. However, in our study, activity abundance and observed species richness of spiders decreased with increasing tree species richness. There was only a weak, non-significant relationship with tree richness when spider richness was rarefied, i.e. corrected for different total abundances of spiders. Only foraging guild richness (i.e. the diversity of hunting modes of spiders was positively related to tree species richness. Plant species richness in the herb layer had no significant effects on spiders. Our results thus provide little support for the enemies hypothesis--derived from studies in less diverse ecosystems--of a positive relationship between predator and plant diversity. Our findings for an important group of generalist predators question whether stronger top-down control of food webs can be expected in the more plant diverse stands of our forest ecosystem. Biotic interactions could play important roles in mediating the observed relationships between spider and plant diversity, but further testing is required for a more detailed mechanistic understanding. Our findings have implications for evaluating the way in which theoretical predictions and experimental findings of functional predator effects apply to species

    Midwifery care has been linked to positive birth outcomes. Despite the broad racial disparities in maternal and infant outcomes in the United States (US), little is known about the role of minority women in either providing or receiving this type of care. A vibrant community of minority women, who self-identify as providing these services, exists online. In this exploratory study we ask how they describe their role; view their practice; and position themselves in the broader discussions of racial health disparities in the US. Using an internet mediated qualitative design we analyse online narratives from self-described African-American nurse-midwives, lay midwives and birth assistants; we found 28 unique websites. We collected and analysed narrative material from each site. We used a thematic analysis approach to identify recurrent and emergent themes in relation to the study question. Narratives identified a strong link to the past, as providers viewed their practice in a historical perspective linking African roots, to the diaspora, and to current African-American struggles. Providers engaged both in direct clinical work, and in activist roles. Advocacy efforts sought to expand numbers of minority birth care workers and to extend the benefits of woman-centred birth care to underserved communities. Results demonstrate the continued existence and important role of diverse types of African-American birth care providers in minority communities in the US. Recognition, support, and increasing the number of midwives of colour is important in tackling racial inequalities in health. Further research should explore minority access to woman-centred care.

    To investigate histologic changes in the mucosa of rat middle ear after implantation of three different support materials. A prospective, controlled animal study. Three types of absorbable materials were implanted into the middle ear cavity of rats: (1) Gelfoam (purified gelatin) (Pharmacia & Upjohn Company, New York, NY), (2) Sepragel (viscoelastic gel composed of cross-linked polymers of hyaluronan) (GENZYME Corp, Ridgefield, NJ), and (3) Nasopore (a biodegradable/fragmentable, synthetic polyurethane foam) (Polyganics, Groningen, The Netherlands). Rats were sacrificed after 3 and 20 days to ascertain early and late histologic changes. The bulla of each rat was excised and prepared for microscopic examination. The histologic changes were evaluated by observation of the middle ear cavity and mucosa in terms of polymorphonuclear leucocytes (PMNL), macrophages, giant cells, fibroblasts and other cells, fibrosis, and remnant materials. The histologic appearance of gelfoam-treated middle ears was characterized by more severe acute inflammation in the short-term and prominent fibrosis in the long-term in comparison with sepragel- and nasopore-treated groups. Nasopore appeared to be prone to remnant formation and reorganization by means of fibroblastic activity. Compared with gelfoam, both sepragel and nasopore caused less histologic alterations.

    Full Text Available Due to its advantageouse characteristic, aluminum is considered to substitute the existing steel as material of the supporting frame of power tiller to meet the strength and environment concerns. The investigation was emphasized on the comparison of both material in view of stress and deformation. In this study, both experimental test and finite element (FE analysis were employed to meet the research concem.comparison between the experimental test and numerical analysis result indicated acceptable differnces of about 7-33% wich is lower than the previouse research. Substitution with aluminum was confirmed using material index that aluminum has better performance in strength and stiffness than that of steel by prescibing minimum better performance in strength and stiffness than that of steel by prescibing minimum weight. FE analysis result revealed that aluminum model was capable of sustaining loads about equal to the steel model. It was based on its maximum von Mises stress wich was insignificatly lower than the steel model. In term of strength characteristic, strength ratio of the aluminum model was higher than the steel model. Furthemore, the substitution also resulted in redistrubuting stress into wider area and mass reduction for about 36%.

    An excessive lumbar load with snow-shoveling is a serious problem in snowfall areas. Various exoskeletal robots have been developed to reduce lumbar load in lifting work. However, few studies have reported the attempt of snow-shoveling work using exoskeletal robots. The purpose of the present study was to test the hypothesis that the HAL for Care Support robot would reduce lumbar load in repetitive snow-shoveling movements. Nine healthy male volunteers performed repetitive snow-shoveling movements outdoors in a snowfall area for as long as possible until they were fatigued. The snow-shoveling trial was performed under two conditions: with and without HAL for Care Support. Outcome measures were defined as the lumbar load assessed by the VAS of lumbar fatigue after the snow-shoveling trial and the snow-shoveling performance, including the number of scoops, and snow shoveling time and distance. The mean of VAS of lumbar fatigue, the number of scoops, and snow-shoveling time and distance without HAL for Care Support were 75.4 mm, 50.3, 145 s, and 9.6 m, while with HAL for Care Support were 39.8 mm, 144, 366 s, and 35.4 m. The reduction of lumbar fatigue and improvement of snow-shoveling performance using HAL for Care Support were statistically significant. There was no adverse event during snow-shoveling with HAL for Care Support. In conclusion, the HAL for Care Support can reduce lumbar load in repetitive snow-shoveling movements.

    Access to youth friendly health services is vital for ensuring sexual and reproductive health (SRH) and well-being of adolescents. This study is a descriptive review of the effectiveness of initiatives to improve adolescent access to and utilization of sexual and reproductive health services (SRHS) in low- and middle-income countries. We examined four SRHS intervention types: (1) facility based, (2) out-of-facility based, (3) interventions to reach marginalized or vulnerable populations, (4) interventions to generate demand and/or community acceptance. Outcomes assessed across the four questions included uptake of SRHS or sexual and reproductive health commodities and sexual and reproductive health biologic outcomes. There is limited evidence to support the effectiveness of initiatives that simply provide adolescent friendliness training for health workers. Data are most ample (10 initiatives demonstrating weak but positive effects and one randomized controlled trial demonstrating strong positive results on some outcome measures) for approaches that use a combination of health worker training, adolescent-friendly facility improvements, and broad information dissemination via the community, schools, and mass media. We found a paucity of evidence on out-of-facility-based strategies, except for those delivered through mixed-use youth centers that demonstrated that SRHS in these centers are neither well used nor effective at improving SRH outcomes. There was an absence of studies or evaluations examining outcomes among vulnerable or marginalized adolescents. Findings from 17 of 21 initiatives assessing demand-generation activities demonstrated at least some association with adolescent SRHS use. Of 15 studies on parental and other community gatekeepers' approval of SRHS for adolescents, which assessed SRHS/commodity uptake and/or biologic outcomes, 11 showed positive results. Packages of interventions that train health workers, improve facility adolescent friendliness

    It can be challenging for support providers to facilitate effective social support interactions even when they have the best intentions. In the current article, we examine some reasons for this difficulty, with a focus on support recipients' self-esteem as a crucial variable. We predicted that recipients' receptiveness to support would be influenced by both support strategy and recipient self-esteem and that receptiveness in turn would impact providers' perceived caregiving efficacy and relationship quality. Study 1 (hypothetical scenarios), Study 2 (confederate interaction), and Study 3 (reports of recently received support) showed that individuals with low self-esteem (LSEs) are less receptive than are individuals with high self-esteem (HSEs) to support that positively reframes their experience but are equally receptive to support that validates their negative feelings. In Study 4, providers demonstrated some knowledge that positive reframing would be less helpful to LSEs than to HSEs but indicated equal intention to give such support. Study 5 showed that, in a real interaction, friends were indeed equally likely to offer positive reframing to both LSEs and HSEs but were less likely to offer validation to LSEs. LSEs were less accepting of such support, and in turn providers felt worse about the interaction, about themselves, and about their friendship more broadly. Study 6 confirmed that recipients' receptivity to support directly influenced providers' experience of a support interaction as well as their self- and relationship evaluations. The findings illustrate how well-meaning support attempts that do not match recipients' particular preferences may be detrimental to both members of the dyad.

    Rational catalyst design necessitates fundamental knowledge on the structure-performance relationship, while the synthetic throughput for heterogeneous Ziegler-Natta olefin polymerization catalysts has long prevented the acquisition of a statistical database. In this contribution, an in-house reactor system was developed to realize the parallel synthesis of support materials for Ziegler-Natta catalysts for the first time. The developed system enabled parallel synthesis of 24 magnesium ethoxide samples with excellent reproducibility and morphological control comparable to a conventional experiment. Our demonstration revealed that the generation of diverse particle characteristics could be achieved through the addition of a third component as a structural modulator, in which the in-house parallel reactor system combined with the first principle component analysis enabled fast screening of effective modulators.

    The Microgravity Materials Science Program established a strong research capability through partnerships between NASA and the scientific research community. With the announcement of the vision for space exploration, additional emphasis in strategic materials science areas was necessary. The President's Commission recognized that achieving its exploration objectives would require significant technical innovation, research, and development in focal areas defined as "enabling technologies." Among the 17 enabling technologies identified for initial focus were: advanced structures, advanced power and propulsion; closed-loop life support and habitability; extravehicular activity systems; autonomous systems and robotics; scientific data collection and analysis, biomedical risk mitigation; and planetary in situ resource utilization. Mission success may depend upon use of local resources to fabricate a replacement part to repair a critical system. Future propulsion systems will require materials with a wide range of mechanical, thermophysical, and thermochemical properties, many of them well beyond capabilities of today's materials systems. Materials challenges have also been identified by experts working to develop advanced life support systems. In responding to the vision for space exploration, the Microgravity Materials Science Program aggressively transformed its research portfolio and focused materials science areas of emphasis to include space radiation shielding; in situ fabrication and repair for life support systems; in situ resource utilization for life support consumables; and advanced materials for exploration, including materials science for space propulsion systems and for life support systems. The purpose of this paper is to inform the scientific community of these new research directions and opportunities to utilize their materials science expertise and capabilities to support the vision for space exploration.

    Full Text Available The purpose of the present work is to use an explicit finite element code to model the impact behavior of a heavyweight impact source like rubber ball and to predict the floor impact vibration of resilient materials, which are used in the floor coverings construction for sound insulation. To simulate the impact force of rubber balls, the hyperviscoelastic rubber model is applied. Then, this rubber model is used in the simulation for the impact vibration of resilient materials. The results indicate that the hyperviscoelastic rubber model could precisely simulate the impact force of rubber balls, as its two parameters are properly chosen according to the desired impact force. Also, the present model could capture the impact and vibration behavior of the considered materials and reasonably evaluate the insulation effect of resilient materials.

    Hydrogen is considered to be an ideal energy alternative to replace environmentally burdensome fossil fuels. For its long-term production the immobilized biofilm system is the most promising and to choose the right support material the most challenging. In this respect, the anaerobic up-flow bioreactors packed with four most used support materials (polyethylene, polyurethane, activated carbon and expanded clay) were tested to investigate the crucial bacteria sensitive period-the immobilization process. Seven-day-operation was necessary and sufficient to reach metabolic and microbial stability regardless of support material used. The support material had an influence on the microbial metabolic activity as well as on quantity and quality characteristics of the immobilized microbial community, being polyethylene and expanded clay more appropriate as supports among the materials evaluated; this could be attributed to pH alteration. The obtained results suggest that the support material dictates the outcome of the immobilization process in the anaerobic continuous-flow bioreactor. Copyright © 2017. Published by Elsevier Ltd.

    2017-10-01

    Full Text Available Fluxgate magnetometers are an important tool in geophysics and space physics but are typically sensitive to variations in sensor temperature. Changes in instrumental gain with temperature, thermal gain dependence, are thought to be predominantly due to changes in the geometry of the wire coils that sense the magnetic field and/or provide magnetic feedback. Scientific fluxgate magnetometers typically employ some form of temperature compensation and support and constrain wire sense coils with bobbins constructed from materials such as MACOR machinable ceramic (Corning Inc. which are selected for their ultra-low thermal deformation rather than for robustness, cost, or ease of manufacturing. We present laboratory results comparing the performance of six geometrically and electrically matched fluxgate sensors in which the material used to support the windings and for the base of the sensor is varied. We use a novel, low-cost thermal calibration procedure based on a controlled sinusoidal magnetic source and quantitative spectral analysis to measure the thermal gain dependence of fluxgate magnetometer sensors at the ppm°C−1 level in a typical magnetically noisy university laboratory environment. We compare the thermal gain dependence of sensors built from MACOR, polyetheretherketone (PEEK engineering plastic (virgin, 30 % glass filled and 30 % carbon filled, and acetal to examine the trade between the thermal properties of the material, the impact on the thermal gain dependence of the fluxgate, and the cost and ease of manufacture. We find that thermal gain dependence of the sensor varies as one half of the material properties of the bobbin supporting the wire sense coils rather than being directly related as has been historically thought. An experimental sensor constructed from 30 % glass-filled PEEK (21.6 ppm°C−1 had a thermal gain dependence within 5 ppm°C−1 of a traditional sensor constructed from MACOR ceramic (8.1

An experimental sensor constructed from 30 % glass-filled PEEK (21.6 ppm°C-1) had a thermal gain dependence within 5 ppm°C-1 of a traditional sensor constructed from MACOR ceramic (8.1 ppm°C-1). If a modest increase in thermal

    This paper evaluates the biological regeneration of ferric Fe3+ solution during desulphurisation of gaseous streams. Hydrogen sulphide (H2S) is absorbed into aqueous ferric sulphate solution and oxidised to elemental sulphur, while ferric ions Fe3+ are reduced to ferrous ions Fe2+. During the industrial regeneration of Fe3+, nutrients and trace minerals usually provided in a laboratory setup are not present and this depletion of nutrients may have a negative impact on the bacteria responsible for ferrous iron oxidation and may probably affect the oxidation rate. In this study, the effect of nutrients and trace minerals on ferrous iron oxidation have been investigated and the results showed that the presence of nutrients and trace minerals affects the efficiency of bacterial Fe2+oxidation. The scanning electron microscopy analysis of the geotextile support material was also conducted and the results showed that the iron precipitate deposits appear to play a direct role on the bacterial biofilm formation.

    Background: Although breast milk has numerous benefits for infants' development, with greater effects in those born preterm (at < 37 gestational weeks), mothers of preterm infants have shorter breastfeeding duration than mothers of term infants. One of the explanations proposed is the difficulties in the transition from a Neonatal Intensive Care Unit (NICU) to the home environment. A person-centred proactive telephone support intervention after discharge from NICU is expected to promote mo...

    To describe how nurse practitioners enact their role in outpatient consultations, and how this compares to their perception of their responsibility for patients with chronic conditions. Nurse practitioners working with patients with chronic conditions seek to support them in self-managing their diseases. An ethnographic study. Episodic participant observations (in total 48 hours) were carried out combined with formal interviews. The study population consisted of a purposive sample of nurse practitioners working in five outpatient clinics related to chronic care in one university medical centre in the Netherlands. Two different types of clinics were selected, namely (1) for patients with episodic flare-ups and (2) for patients with diseases requiring life-saving procedures. The nurse practitioners perceived the monitoring of patients' treatment as their main professional responsibility. Four monitoring strategies could be distinguished: 'assessing health conditions', 'connecting with patients', 'prioritising treatment in daily living' and 'educating patients'. While nurse practitioners considered building a relationship with their patients of utmost importance, their consultations were mostly based on a conventional medical model of medical history taking. Little attention was paid to the social, psychological and behavioural dimensions of illness. Nurse practitioners in this study seemed quite successful in their extension into medical territory, but moving patients' illness perceptions to the background was not conducive to self-management support. By their medical subspecialty expertise, nurse practitioners have a major role in the longitudinal process of the management of chronic diseases' treatment. Supporting patients to reduce the impact of the disease and its complications requires nurse practitioners to develop new coaching strategies designed to meet patients' individual needs. © 2016 John Wiley & Sons Ltd.

    Evidence from neuroimaging studies suggests that intelligence differences may be supported by a parieto-frontal network. Research shows that this network is also relevant for cognitive functions such as working memory and attention. However, previous studies have not explicitly analyzed the commonality of brain areas between a broad array of intelligence factors and cognitive functions tested in the same sample. Here fluid, crystallized, and spatial intelligence, along with working memory, executive updating, attention, and processing speed were each measured by three diverse tests or tasks. These twenty-one measures were completed by a group of one hundred and four healthy young adults. Three cortical measures (cortical gray matter volume, cortical surface area, and cortical thickness) were regressed against psychological latent scores obtained from a confirmatory factor analysis for removing test and task specific variance. For cortical gray matter volume and cortical surface area, the main overlapping clusters were observed in the middle frontal gyrus and involved fluid intelligence and working memory. Crystallized intelligence showed an overlapping cluster with fluid intelligence and working memory in the middle frontal gyrus. The inferior frontal gyrus showed overlap for crystallized intelligence, spatial intelligence, attention, and processing speed. The fusiform gyrus in temporal cortex showed overlap for spatial intelligence and attention. Parietal and occipital areas did not show any overlap across intelligence and cognitive factors. Taken together, these findings underscore that structural features of gray matter in the frontal lobes support those aspects of intelligence related to basic cognitive processes.

  11. Challenges to Providing a Successful Central Configuration Service to Support CERN’s New Controls Diagnostics and Monitoring System

    CERN Document Server

    Makonnen, Z; Zaharieva, Z

    2014-01-01

    The Controls Diagnostic and Monitoring service (DIAMON) provides monitoring and diagnostics tools to the operators in the CERN Control Centre. A recent reengineering presented the opportunity to restructure its data management and to integrate it with the central Controls Configuration Service (CCS). The CCS provides the Configuration Management for the Controls System for all accelerators at CERN. The new facility had to cater for the configuration management of all agents monitored by DIAMON, (>3000 computers of different types), provide deployment information, relations between metrics, and historical information. In addition, it had to be integrated into the operational CCS, while ensuring stability and data coherency. An important design decision was to largely reuse the existing infrastructure in the CCS and adapt the DIAMON data management to it e.g. by using the device/property model through a Virtual Devices framework to model the DIAMON agents. This article will show how these challenging requiremen...

    Surrey Satellite Technology Ltd has reviewed the ability of small satellites to provide additional capability to the presently defined Global Monitoring for Environment and Security (GMES) space segment, allowing the broadest set of user requirements to be met. User- focused services have been compared with the instruments defined for the currently proposed Sentinels. SSTL has developed the Disaster Monitoring Constellation (DMC) of small satellites at a very low cost, which provide land-focused data products in the visible wavebands with daily access capability. The study undertaken by SSTL for the European Space Agency analysed the DMC operational concept in a GMES context, reviewing a range of possible services with different payload configurations on small satellite platforms. One concept was selected and an appropriate payload definition derived. The chosen mission concept was based on the provision of near time operational oceanography information using a constellation of small satellites. The aim is to provide sea surface height, significant wave height and wind speed.

    Full Text Available Abstract Background Better use of e-health services by patients could improve outcomes and reduce costs but there are concerns about inequalities of access. Previous research in outpatients suggested that anonymous personal email support may help patients with long term conditions to use e-health, but recruiting earlier in their 'journey' may benefit patients more. This pilot study explored the feasibility and cost of recruiting patients for an e-health intervention in one primary care trust. Methods The sample comprised 46 practices with total patient population of 250,000. We approached all practices using various methods, seeking collaboration to recruit patients via methods agreed with each practice. A detailed research diary was kept of time spent recruiting practices and patients. Researcher time was used to estimate costs. Patients who consented to participate were offered email support for their use of the Internet for health. Results Eighteen practices agreed to take part; we recruited 27 patients, most (23/27 from five practices. Practices agreed to recruit patients for an e-health intervention via waiting room leaflets (16, posters (16, practice nurses (15, doctors giving patients leaflets (5, a study website link (7, inclusion in planned mailshots (2, and a special mailshot to patients selected from practice computers (1. After low recruitment response we also recruited directly in five practices through research assistants giving leaflets to patients in waiting rooms. Ten practices recruited no patients. Those practices that were more difficult to recruit were less likely to recruit patients. Leaving leaflets for practice staff to distribute and placing posters in the practice were not effective in recruiting patients. Leaflets handed out by practice nurses and website links were more successful. The practice with lowest costs per patient recruited (£70 used a special mailshot to selected patients.

    To address the problem of overweight and obesity in Mexico, in 2010 the Acuerdo Nacional para la Salud Alimentaria was published. At school level, food service providers were considered essential to comply with certain commitments. The goal of this intervention was to train school food service providers in school eating establishments (SEE) as to the criteria in the general guidelines for the sale and distribution of food in schools of basic education. 13 SEE in San Luis Potosi participated. Based on an initial diagnosis, a class-workshop of 5 sessions was designed. Knowledge regarding food was evaluated at the beginning and end of the sessions. The percentage of adherence regarding general hygiene and food preparation and distribution was obtained at the beginning, one month, and two months post-intervention. School food service providers had little knowledge on the objectives of the Acuerdo in food groups and combination, as well as reading labels; there were significant changes in the last two after intervention. The initial percentage of overall hygiene compliance was 60 %, with an increase of almost 20 % post-training. The preparation and distribution of food did not show significant changes. School food service providers acquired knowledge about the guidelines that a SEE comply with, without putting them into practice, given the economic impact that it implies.

    A specific set of assessment scales can underpin the management of distressing symptoms of patients requiring palliative care. A research assistant supported nurses working in a rural hospital setting during the introduction of these scales. A secondary analysis was conducted to further explore the qualitative data of a previously reported mixed-method study. In particular, the experiences of nurses working alongside a research assistant in the facilitation of using a new assessment form. Purposeful sampling was employed: participating nurses were invited to attend one of three focus group meetings. Data analysis revealed three main themes: a contact person, coach/mentor and extra help initiatives. Three to four subthemes corresponded with each main theme. Findings suggest nurses benefit from having someone to assist in learning about new documentation. Nurses respond positively to mentorship and practical guidance when integrating a new assessment form into routine evidence-based practice.

    Earnest efforts have been taken to design hybrid energy storage devices using hybrid electrodes based on capacitive (rGO) and pseudocapacitive (Ni(OH)2 and Co(OH)2) materials deposited on the skeleton of 3D macroporous (indicate sponge material) sponge support. Conducting framework was formed by coating rGO on macroporous sponge on which subsequent deposition of Ni(OH)2 and Co(OH)2 was carried out. The synergetic combination of rGO and Ni(OH)2 or Co(OH)2) provides dual charge-storing mechanisms whereas 3D framework of sponge allows excellent accessibility of electrolyte to hybrid electrodes. Moreover, to further increase the energy density, hybrid devices have been fabricated with SP@rGO@Ni or SP@rGO@Co and SP@rGO as positive and negative electrodes, respectively. These hybrid devices operate with extended operating voltage windows and achieve remarkable electrochemical supercapacitive properties which make them truly promising energy storage devices for commercial production.

    Pre-operative psychological assessment is recommended by international guidelines for bariatric surgery candidates. Thereby, service teams caring for bariatric patients should include at least one mental health provider (e.g., a psychologist or psychiatrist). The objective of this study was to evaluate the psychology and psychiatry resources and practices in the 37 specialized obesity centers (CSOs) created by the French Ministry of Health. CSO coordinators were contacted by e-mail to collect general information on the centers (e.g., number of bariatric operations). Secondly, psychologists and psychiatrists of each center completed an anonymous questionnaire assessing their professional practices and their organization of care pathways. The vast majority of CSO coordinators (81%, n = 26/32) answered our survey. These results show significant differences and shortages in terms of the psychology/psychiatry resources available. Most of the psychologists (n = 26/31) and psychiatrists (n = 10/10) stated that they systematically meet new patients only before surgery (56%) or both before and after the operation (30%); however, some psychologists and psychiatrists (14%) do not systematically meet all the patients (before and/or after surgery). Nevertheless, all the professionals provide psychology assessments, and about 75% of them offer a psychological follow-up, indicating a similarity regarding the practices of psychologists and psychiatrists. Our results highlight the place of psychological/psychiatric evaluations in French CSOs and emphasize the absence of mental health providers in several of these services. Post-operative psychological follow-up is not usually provided. It would be appropriate to create clear recommendations for post-operative psychological or psychiatric long-term follow-up.

    Tactical teams are at high risk of sustaining injuries. Caring for these casualties in the field involves unique requirements beyond what is provided by traditional civilian emergency medical services (EMS) systems. Despite this need, the training objectives and competencies are not uniformly agreed to or taught. An expert panel was convened that included members from the Departments of Defense, Homeland Security, Justice, and Health and Human Services, as well as federal, state, and local law-enforcement officers who were recruited through requests to stakeholder agencies and open invitations to individuals involved in Tactical Emergency Medical Services (TEMS) or its oversight. Two face-to-face meetings took place. Using a modified Delphi technique, previously published TEMS competencies were reviewed and updated. The original 17 competency domains were modified and the most significant changes were the addition of Tactical Emergency Casualty Care (TECC), Tactical Familiarization, Legal Aspects of TEMS, and Mass Casualty Triage to the competency domains. Additionally, enabling and terminal learning objectives were developed for each competency domain. This project has developed a minimum set of medical competencies and learning objectives for both tactical medical providers and operators. This work should serve as a platform for ensuring minimum knowledge among providers, which will serve enhance team interoperability and improve the health and safety of tactical teams and the public. 2014.

    Research among cancer patients has shown that emotional support in informal relationships may be difficult to access because of a fear or lack of knowledge about cancer. Consequently, formal relationships with healthcare professionals may be important sources of support. This study explores needs for and experiences with emotional support provided by nurses as well as prerequisites for the provision of support among Danish-born and migrant cancer patients. We conducted narrative interviews with 18 adult Danish-born and migrant cancer patients. Patients were recruited from a variety of places in a purposive strategic sampling process. Analysis was inspired by phenomenological methods and Simmel's theoretical concept of "the stranger". Both Danish-born and migrant patients perceived the support delivered by healthcare professionals as available, empathic and valuable. Prerequisites for providing emotional support were 1) setting aside time for the patient to feel safe and able to verbalise emotional concerns, 2) continuity in relationships with healthcare professionals, and 3) nurses' ability to understand the patient's emotional reactions without creating additional distress. Being positioned as a stranger to the patient gives nurses a unique position from which to provide emotional support during cancer treatment. Thus, formal relationships with healthcare professionals are of great importance for many cancer patients.

    The packaging materials industry has already recognized the importance of Total Productive Maintenance as a system of proactive techniques for improving equipment reliability. Bearing faults, which often occur gradually, represent one of the foremost causes of failures in the industry. Therefore, detection of their faults in an early stage is quite important to assure reliable and efficient operation. We present a new automated technique for early fault detection and diagnosis in rolling-element bearings based on vibration signal analysis. Following the wavelet decomposition of vibration signals into a few sub-bands of interest, the standard deviation of obtained wavelet coefficients is extracted as a representative feature. Then, the feature space dimension is optimally reduced to two using scatter matrices. In the reduced two-dimensional feature space the fault detection and diagnosis is carried out by quadratic classifiers. Accuracy of the technique has been tested on four classes of the recorded vibrations signals, i.e., normal, with the fault of inner race, outer race, and ball operation. The overall accuracy of 98.9% has been achieved. The new technique can be used to support maintenance decision-making processes and, thus, to increase reliability and efficiency in the industry by preventing unexpected faulty operation of bearings.

    A new alumina supported carbon composite material called "Eggshell Composite" (EC) was synthesized from eggshell waste as calcium source for selective fluoride adsorption from water. The effect of various synthesis parameters like eggshell (ES): Eggshell membrane (ESM) ratio, aluminium loading, mixing time and calcinations temperature to optimize the synthesis conditions for selective fluoride removal has been studied. It was observed that the synthesis parameters have significant influence on development of EC and in turn on fluoride removal capacity. EC synthesized was characterized for elemental composition, morphology, functionality and textural properties. Results showed that EC obtained from eggshell modified with alumina precursor is more selective and efficient for fluoride removal. Langmuir and Freundlich isotherm were used to obtain ultimate fluoride removal capacity. The calcium and alumina species in EC shows synergistic effect in fluoride adsorption process. Fluoride sorption studies were carried out in synthetic, groundwater and wastewater. EC proved to be a potential, indigenous and economic adsorbent for fluoride removal.

    Immobilized enzymes can be used in a wide range of processes. In recent years, a variety of new approaches have emerged for the immobilization of enzymes that have greater efficiency and wider usage. During the course of the last two decades, this area has rapidly expanded into a multidisciplinary field. This current study is a comprehensive review of a variety of literature produced on the different enzymes that have been immobilized on various supporting materials. These immobilized enzymes have a wide range of applications. These include applications in the sugar, fish, and wine industries, where they are used for removing organic compounds from waste water. This study also reviews their use in sophisticated biosensors for metabolite control and in situ measurements of environmental pollutants. Immobilized enzymes also find significant application in drug metabolism, biodiesel and antibiotic production, bioremediation, and the food industry. The widespread usage of immobilized enzymes is largely due to the fact that they are cheaper, environment friendly, and much easier to use when compared to equivalent technologies. © 2016 Elsevier Inc.

Accuracy of the technique has been tested on four classes of the recorded vibrations signals, i.e., normal, with the fault of inner race, outer race, and ball operation. The overall accuracy of 98.9% has been achieved. The new technique can be used to support maintenance decision-making processes and, thus, to increase reliability and efficiency in the industry by preventing unexpected faulty operation of bearings.

    Antisense transcripts of Ultrabithorax (aUbx) in the millipede Glomeris and the centipede Lithobius are expressed in patterns complementary to that of the Ubx sense transcripts. A similar complementary expression pattern has been described for non-coding RNAs (ncRNAs) of the bithoraxoid (bxd) locus in Drosophila, in which the transcription of bxd ncRNAs represses Ubx via transcriptional interference. We discuss our findings in the context of possibly conserved mechanisms of Ubx regulation in myriapods and the fly.Bicistronic transcription of Ubx and Antennapedia (Antp) has been reported previously for a myriapod and a number of crustaceans. In this paper, we show that Ubx/Antp bicistronic transcripts also occur in Glomeris and an onychophoran, suggesting further conserved mechanisms of Hox gene regulation in arthropods.Myriapod monophyly is supported by the expression of aUbx in all investigated myriapods, whereas in other arthropod classes, including the Onychophora, aUbx is not expressed. Of the two splice variants of Ubx/Antp only one could be isolated from myriapods, representing a possible further synapomorphy of the Myriapoda.

    Despite advances in the quality and availability of hospice and palliative care for people with end stage cancers, research addressing the psychosocial needs of family members and concerned others during the dying process has been limited primarily to caregivers. In addition, many of these studies focused on the recently bereaved. In this study, the authors sought to broaden that perspective by examining the psychosocial needs of secondary survivors, a term that applies to caregivers, family members, and others who felt a caring bond with a dying person. A qualitative exploration of needs expressed by secondary survivors following the conclusion of a structured 8-week psychoeducational grief group experience revealed that secondary cancer survivors experience a sense of isolation and powerlessness that is often unrecognized by physicians, nurses, oncology social workers, or other health care professionals. Furthermore, these secondary survivors needed support that extends well beyond activities that are traditionally associated with the physical and emotional care of the dying. Social work intervention strategies directed toward helping secondary survivors assert personal needs, develop greater proximity with the health care team, and prepare for the processes associated with end-of-life may be helpful later during bereavement.

    Full Text Available Abstract Introduction Effective delivery of cardiopulmonary resuscitation (CPR and prompt defibrillation following sudden cardiac arrest (SCA is vital. Updated guidelines for adult basic life support (BLS were published in 2010 by the European Resuscitation Council (ERC in an effort to improve survival following SCA. There has been little assessment of the ability of rescuers to meet the standards outlined within these new guidelines. Methods We conducted a retrospective analysis of the performance of first year healthcare students trained and assessed using either the new 2010 ERC guidelines or their 2005 predecessor, within the University of Birmingham, United Kingdom. All students were trained as lay rescuers during a standardised eight hour ERC-accredited adult BLS course. Results We analysed the examination records of 1091 students. Of these, 561 were trained and assessed using the old 2005 ERC guidelines and 530 using the new 2010 guidelines. A significantly greater proportion of candidates failed in the new guideline group (16.04% vs. 11.05%; p  Conclusions The new ERC guidelines lead to a greater proportion of lay rescuers performing chest compressions at an erroneously fast rate and may therefore worsen BLS efficacy. Additional study is required in order to define the clinical impact of compressions performed to a greater depth and at too fast a rate.

    Full Text Available This study aims to give a deeper understanding on emerging business models in the context of education. Industry 4.0/the Industrial Internet in general and especially recent advances in cloud computing enable a new kind of service offering in the education sector and lead to new business models for education: Education-as-a-Service (EaaS. Within EaaS, learning, and teaching contents are delivered as services. By combining a literature review with a qualitative case study, this paper makes a three-fold contribution to the field of business models in education: First, we provide a theoretical definition for a common understanding of EaaS. Second, we present the state-of-the-art research on this new paradigm. Third, in the case study we describe a “best practices” business model of an existing EaaS provider. These insights build a theoretical foundation for further research in this area. The paper concludes with a research agenda for further research in this emerging field.

    To describe the phases of the cancer trajectory when social support, in the form of electronic counselling services, as provided by the non-profit cancer societies, is needed, as well as how these services are integrated into the cancer care in public healthcare. In this descriptive qualitative study a purposive sample of patients with cancer (n = 12) were interviewed. The data were content analysed inductively. Social support was needed when emotional well-being was weakened, when the body broke, when the care pathway induced unawareness, and when empowerment needed strengthening. There was no need for social support when well-being was considered in balance. The electronic counselling services were integrated into cancer care by supporting the patient with cancer emotionally, developing the informational expertise of the patient with cancer, expanding the opportunities for support, and supporting public healthcare. Integration required improvements to the actions of the patients and various actors involved in the healthcare system. There was no integration due to the health status of the patient and the sufficiency of the primary support sources. The received social support was not integrated into the actual cancer treatment process of the patient with cancer in the public healthcare system. The phases of support needed in the cancer trajectory as defined by the patient differ from the traditional biomedical phases of treatment. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Even if patients with terminal cancer hope to spend the rest of their lives at home, they are often unable to leave the hospital early due to their family caregivers' anxiety. This study aimed to investigate in Japan the discrepancies between the supports needed by and actually provided by palliative care unit nurses (PCUNs) to the family caregivers for discharge of patients with terminal cancer. In this cross-sectional study, self-administered questionnaires including 6-point Likert-type scales assessing the reasons for difficulties in transition to home-based care were distributed to 1227 PCUNs. Using paired t tests, the differences between the scores on perceived importance and actual supports to family caregivers were examined. The supports actually provided were classified by factor analysis. The relationships between the PCUNs' characteristics and mean scores on the supports in each category were examined using multiple regression analysis. A total of 1023 (83.4%) completed questionnaires were returned. Scores on the actually provided supports for discharge to family caregivers were consistently and significantly lower than the corresponding scores on perceived importance for all 57 items ( P care, receiving necessary training, cooperating with palliative care staff, and cooperating with local service providers were significantly associated with higher levels of actual supply of supports to family caregivers. Our findings suggest that PCUNs need to be encouraged to provide further support to family caregivers for the discharge of patients with terminal cancer.

    Although widely available, the general public, cancer patients, and cancer survivors have difficulties accessing evidence-based information on nutrition and cancer. It is challenging to distinguish myths from facts, and sometimes conflicting information can be found in different places. The public and patients would benefit from evidence-based, correct, and clear information from an easily recognizable source. The aim of this project is to make scientific information available for the general public, cancer patients, and cancer survivors through a website. The aim of this paper is to describe and evaluate the development of the website as well as related statistics 1st year after its launch. To develop the initial content for the website, the website was filled with answers to frequently asked questions provided by cancer organizations and the Dutch Dietetic Oncology Group, and by responding to various fiction and facts published in the media. The website was organized into 3 parts, namely, nutrition before (prevention), during, and after cancer therapy; an opportunity for visitors to submit specific questions regarding nutrition and cancer was included. The website was pretested by patients, health care professionals, and communication experts. After launching the website, visitors' questions were answered by nutritional scientists and dieticians with evidence- or eminence-based information on nutrition and cancer. Once the website was live, question categories and website statistics were recorded. Before launch, the key areas for improvement, such as navigation, categorization, and missing information, were identified and adjusted. In the 1st year after the launch, 90,111 individuals visited the website, and 404 questions were submitted on nutrition and cancer. Most of the questions were on cancer prevention and nutrition during the treatment of cancer. The website provides access to evidence- and eminence-based information on nutrition and cancer.

    Despite the importance of adequate, un-crowded housing as a prerequisite for good health, few large cohort studies have explored the health effects of housing conditions. The Social Housing Outcomes Worth (SHOW) Study was established to assess the relationship between housing conditions and health, particularly between household crowding and infectious diseases. This paper reports on the methods and feasibility of using a large administrative housing database for epidemiological research and the characteristics of the social housing population. This prospective open cohort study was established in 2003 in collaboration with Housing New Zealand Corporation which provides housing for approximately 5% of the population. The Study measures health outcomes using linked anonymised hospitalisation and mortality records provided by the New Zealand Ministry of Health. It was possible to match the majority (96%) of applicant and tenant household members with their National Health Index (NHI) number allowing linkage to anonymised coded data on their hospitalisations and mortality. By December 2011, the study population consisted of 11,196 applicants and 196,612 tenants. Half were less than 21 years of age. About two-thirds identified as Māori or Pacific ethnicity. Household incomes were low. Of tenant households, 44% containing one or more smokers compared with 33% for New Zealand as a whole. Exposure to household crowding, as measured by a deficit of one or more bedrooms, was common for applicants (52%) and tenants (38%) compared with New Zealanders as whole (10%). This project has shown that an administrative housing database can be used to form a large cohort population and successfully link cohort members to their health records in a way that meets confidentiality and ethical requirements. This study also confirms that social housing tenants are a highly deprived population with relatively low incomes and high levels of exposure to household crowding and environmental

    Advances in technology have offered health professionals alternative mediums of providing support to patients with long-term conditions. This critical review evaluated and assessed the benefit of electronic media technologies in supporting children and young people with long-term conditions. Of 664 references identified, 40 met the inclusion criteria. Supportive technology tended to increase disease-related knowledge and improve aspects of psychosocial function. Supportive technology did not improve quality of life, reduce health service use or decrease school absences. The poor methodological quality of current evidence and lack of involvement of users in product development contribute to the uncertainty that supportive technology is beneficial.

    To investigate the associations of self-perceived competence in diabetes management and autonomy support from healthcare providers with diabetes distress in adults with Type 1 diabetes mellitus that is not optimally controlled [HbA(1c) ≥ 64 mmol/mol (8.0%)]. This cross-sectional study comprised blood sampling and three self-report questionnaires, the Problem Areas in Diabetes scale, the Perceived Competence in Diabetes Scale and a measure of autonomy support by healthcare providers, the Health Care Climate Questionnaire. We fitted blockwise linear regression models to assess the associations between Problem Areas in Diabetes score and the variables of interest (autonomy support and perceived diabetes competence), controlling for clinical and sociodemographic variables. Of the study sample [n = 178; mean age 36.7 (±10.7) years], 31.5% had long-term complications and 43.2% reported elevated (≥40) Problem Areas in Diabetes scores. A significant negative association was found between autonomy support and Problem Areas in Diabetes score (B = -3.61, P = 0.001), indicating that lower autonomy support was associated with greater diabetes distress. When perceived competence was controlled, it mediated the association of autonomy support with diabetes distress, reducing it to non-significance. There was a significant negative association between perceived competence and Problem Areas in Diabetes score (B = -8.89, P autonomy support and diabetes distress; autonomy support was associated with increased perceived competence, which, in turn, was associated with reduced distress. Healthcare providers' communication styles enhancing perceived competence through autonomy support may contribute to effective treatment for people with Type 1 diabetes and suboptimum glycaemic control. © 2015 The Authors.

    Full Text Available Here an efficient displacement potential formulation based finite difference technique is used to solve the elastic field of a simply supported beam of orthotropic composite materials. A simply supported beam made of orthotropic composite material under uniformly distributed loading is considered and its elastic behaviors under such loading conditions are analyzed considering plane stress condition. The solutions of the problem satisfy the force equilibrium conditions as well as boundary conditions. For understanding the elastic behavior of a simply supported beam, the displacement and stress components of some important sections of the beam are shown graphically. Effects of different orthotropic composite materials on the solutions are also analyzed. Besides, at a particular section of the beam, the comparative analysis of the elastic field is carried out by using the FDM and FEM methods.

    Full Text Available In an Enterprise Resource Planning (ERP system, production planning is influenced by a variety of parameters. Previous investigations show that setting parameter values is highly relevant to a company’s target system. Parameter settings should be checked and adjusted, e.g., after a change in environmental factors, by material planners. In practice, updating the parameters is difficult due to several reasons. This paper presents a simulation-based decision support system, which helps material planners in all stages of decision-making processes. It will present the system prototype’s user interface and the results of applying the system to a case study.

    Full Text Available Dr MathTM is a mobile, online tutoring system where learners can use MXitTM on their mobile phones to receive help with their mathematics homework from volunteer tutors. These conversations between learners and Dr Math are held in MXit lingo. MXit lingo is a heavily abbreviated, English-like language that is evolving between users of mobile phones that communicate using MXit. The Dr Math project has been running since January 2007 and uses volunteer tutors who are mostly university students who readily understand and use MXit lingo. However, due to the large number of simultaneous conversations that the tutors are often involved in and the diversity of topics discussed, it would often be beneficial to provide assistance regarding the mathematics topic to the tutors. This article explains how the μ model identifies the mathematics topic in the conversation. The model identifies appropriate mathematics topics in just over 75% of conversations in a corpus of conversations identified to be about mathematics topics in the school curriculum.

    The Thana Resource Development and Employment Project (TRDEP), built upon the successful experience of the Grameen Bank and other nongovernmental organizations, is a comprehensive poverty alleviation scheme implemented by the government of Bangladesh and targeted to the poorest segment of Bangladeshi society. The project provides soft loans to landless poor for income-generating activities involving non-crop livelihoods and trades. The loans are granted at an 18% interest rate including a 2% charge which goes into a risk fund. The poorest of poor are eligible to receive loans as long as each borrowing unit is a self-help group comprised of five members of one family and each member of the group assumes the responsibility of paying each other member's loan. Each member of a borrowing group may receive loans in the amount of Taka 3000-5000 (US$75-125). The loans are then repayable in 50 equal installments over the course of 1 year. One member's default disqualifies all other group members from receiving future credit until the default is cleared. TRDEP borrowers have started small, successful entrepreneurial activities with their loans as capital.

    Aromatherapy has been used to reduce anxiety in a variety of settings, but usefulness associated with breast biopsies has not been documented. This study was conducted in women undergoing image-guided breast biopsy. We explored the use of two different aromatherapy scents, compared to placebo, aimed at reducing anxiety with the intent of generating new knowledge. This was a randomized, placebo-controlled study of two different types of external aromatherapy tabs (lavender-sandalwood and orange-peppermint) compared with a matched placebo-control delivery system. Anxiety was self-reported before and after undergoing a breast biopsy using the Spielberger State Anxiety Inventory Scale. Eighty-seven women participated in this study. There was a statistically significant reduction in self-reported anxiety with the use of the lavender-sandalwood aromatherapy tab compared with the placebo group (p = .032). Aromatherapy tabs reduced anxiety during image-guided breast biopsy. The completion of the biopsy provided some relief from anxiety in all groups. The use of aromatherapy tabs offers an evidence-based nursing intervention to improve adaptation and reduce anxiety for women undergoing breast biopsy. Lavender-sandalwood aromatherapy reduced anxiety and promoted adaptation more than orange-peppermint aromatherapy or placebo. © 2017 Sigma Theta Tau International.

    The impact of prosthetic material selection on implant survival is not clear. The current criteria for choosing a prosthetic material seem to be based on clinician preferences. This systematic review aims to evaluate the impact of restorative materials on the mid- and long-term survival of implants supporting single crowns and fixed partial dentures. Hand and MEDLINE searches were performed to identify relevant literature for single crowns (SC) and fixed partial dentures (FPD). Further inclusion criteria were a mean follow-up period of at least 3 years, the inclusion of at least 10 patients in a relevant study cohort, and a clear description of prosthesis type and prosthetic material. A total of 63 studies for the SC group and 11 studies for the FPD group were included. Full arch restorations were not included. The materials utilised in the SC group were metal-ceramic (precious and non-precious), lithium-disilicate, veneered zirconia, veneered alumina, and nanoceramics. The materials used in the FPD group were metal-ceramic (precious), veneered titanium, metal-resin (precious), and veneered zirconia. No significant impact on the prosthetic material relating to mid- or long-term implant survival was identified. Furthermore, there were no statistically significant differences between the survival rates of the dental prostheses made from different materials (SC and FPD group). Single crowns made of nanoceramics showed a higher risk for decementation relative to other materials (0.80, 95% CI [0.67; 0.89]; P material selection has no influence on mid- and long-term survival of implants restored with single crowns and fixed partial dentures. Similarly, the prosthetic material seems to have no significant impact on prosthetic survival rates. Further research is required to provide more evidence regarding the impact of the prosthetic material on long-term outcome.

    The ratification and ongoing implementation of the New START Treaty have been widely regarded as noteworthy global security achievements for both the Obama Administration and the Putin (formerly Medvedev) regime. But deeper cuts that move beyond the United States and Russia to engage the P-5 and other nuclear weapons possessor states are envisioned under future arms control regimes, and are indeed required for the P-5 in accordance with their Article VI disarmament obligations in the Nuclear Non-Proliferation Treaty. Future verification needs will include monitoring the cessation of production of new fissile material for weapons, monitoring storage of warhead components and fissile materials and verifying dismantlement of warheads, pits, secondary stages, and other materials. A fundamental challenge to implementing a nuclear disarmament regime is the ability to thwart unauthorized material diversion throughout the dismantlement and disposition process through strong chain of custody implementation. Verifying the declared presence, or absence, of nuclear materials and weapons components throughout the dismantlement and disposition lifecycle is a critical aspect of the disarmament process. From both the diplomatic and technical perspectives, verification under these future arms control regimes will require new solutions. Since any acceptable verification technology must protect sensitive design information and attributes to prevent the release of classified or other proliferation-sensitive information, non-nuclear non-sensitive modalities may provide significant new verification tools which do not require the use of additional information barriers. Alternative verification technologies based upon electromagnetic and acoustics could potentially play an important role in fulfilling the challenging requirements of future verification regimes. For example, researchers at the Pacific Northwest National Laboratory (PNNL) have demonstrated that low frequency electromagnetic

    Most professional organizations now provide patient information material, and not all of this material is appropriate for the average American adult to comprehend. The National Institutes of Health (NIH) and the United States Department of Health and Human Services recommend that patient education materials be written at the sixth-grade level. Our aim was to assess the readability of neurosurgery-related patient education material and compare it with The American Medical Association, NIH, and United States Department of Health and Human Services recommendations. Materials provided by the American Association of Neurologic Surgeons (AANS) and the U.S. National Library of Medicine (NLM) and National Institutes of Health were assessed with the Flesch-Kincaid grade level and Flesch Reading Ease score with Microsoft Office Word software. None of the articles had Flesch-Kincaid grade levels at or below the sixth-grade level. All articles on the AANS Conditions and Treatments section were written at or above the ninth-grade level; three of the AANS Camera-Ready Fact Sheets and four of the NIH/NLM articles were written between the seventh- and eighth-grade levels. Current patient education material provided by the AANS is written well above the recommended level. Material from the NLM and NIH performed better, but was still above the recommended sixth-grade level.

    Report RWEV-REP-001, Analysis of Postclosure Groundwater Impacts for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High Level Radioactive Waste at Yucca Mountain, Nye County, Nevada was issued by the DOE in 2009 and is currently being updated. Sandia National Laboratories (SNL) provided support for the original document, performing calculations and extracting data from the Yucca Mountain Performance Assessment Model that were used as inputs to the contaminant transport and dose calculations by Jason Associates Corporation, the primary developers of the DOE report. The inputs from SNL were documented in LSA-AR-037, Inputs to Jason Associates Corporation in Support of the Postclosure Repository Supplemental Environmental Impact Statement. To support the updating of the original Groundwater Impacts document, SNL has reviewed the inputs provided in LSA-AR-037 to verify that they are current and appropriate for use. The results of that assessment are documented here.

    Low-dose computed tomography (LDCT) screening is a promising screening modality for increasing the detection rate of early stage lung cancers among high-risk individuals. Despite being recommended by the US Preventative Services Task Force, uptake of LDCT remains low. The objective of the current study was to gather feedback from high-risk consumers and health care providers on LDCT promotional materials. Focus group discussions were conducted with high-risk individuals (8 focus groups; N = 38) and primary care providers (9 focus groups; N = 23). Participants reviewed existing LDCT promotional materials to assess their perceptions of media materials created to publicize LDCT. Data were analyzed using the constant comparative method. Several key themes emerged from focus groups that can be used to inform development of future LDCT promotional materials. High-risk (HR) participants expressed greater receptivity for promotional materials that did not further stigmatize lung cancer and/or smoking and expressed preferences for materials that clearly outlined the risks/benefits of screening. Primary care providers (PCPs) offered suggestions to facilitate the referral process such as diagnostic codes and requested a design that clearly outlined eligibility criteria. A clear and thorough explanation of LDCT eligibility, cost, harms, and benefits was of chief importance for both PCP and HR audiences. Given that PCPs and HR audiences are not well informed on the specifics of LDCT screening eligibility and insurance coverage, creating provider and patient education opportunities will aid in shared decision-making opportunities. Promotional materials that meet the needs of the target audience are needed to facilitate discussions of risks/benefits of screening with HR individuals.

    To investigate the force absorption capacity of implant-supported crowns made of different restorative materials and connected to abutments with different luting agents. Molar crowns were milled of different computer-aided design/computer-aided manufacture materials (n = 8 crowns per material): polymethyl methacrylate, polyether ether ketone, composite, lithium disilicate, titanium, and zirconia. Crowns were mounted on titanium implant replicas using different luting agents: uncemented, temporarily cemented (zinc oxide-eugenol cement), conventionally cemented (zinc oxide phosphate cement), and adhesively bonded. As a reference, one implant replica was tested without a crown. Force absorptions of the different combinations of crown materials and luting agents were determined by applying an increasing force (0 to 250 N) on the occlusal crown surface and measuring the resulting force below the implant. Mean curves of applied and resulting forces up to 200 N were determined (six measurements per group), and slopes were calculated. Statistical analysis was performed (one-way analysis of variance, Bonferroni post hoc test, α = .05). Significant (P crown materials that were uncemented, temporarily cemented, cemented, and adhesively bonded. Materials with higher moduli of elasticity (ceramics, titanium) showed steeper slopes of the force curves and lower shock-absorbing capacity than resin-based materials, but were influenced more by the luting agents. The damping effects of resin-based materials were higher in combination with all cementation and luting modes. Shock absorption tests exhibited a strong material-dependent damping behavior of implant-supported crowns. The shock-absorbing capacity of crown materials with high moduli of elasticity may benefit from conventional cementation.

    Abstract Background Combating the spread of drug resistant tuberculosis is a global health priority. Whole genome association studies are being applied to identify genetic determinants of resistance to anti-tuberculosis drugs. Protein structure and interaction modelling are used to understand the functional effects of putative mutations and provide insight into the molecular mechanisms leading to resistance. Methods To investigate the potential utility of these approaches, we analysed the genomes of 144 Mycobacterium tuberculosis clinical isolates from The Special Programme for Research and Training in Tropical Diseases (TDR) collection sourced from 20 countries in four continents. A genome-wide approach was applied to 127 isolates to identify polymorphisms associated with minimum inhibitory concentrations for first-line anti-tuberculosis drugs. In addition, the effect of identified candidate mutations on protein stability and interactions was assessed quantitatively with well-established computational methods. Results The analysis revealed that mutations in the genes rpoB (rifampicin), katG (isoniazid), inhA-promoter (isoniazid), rpsL (streptomycin) and embB (ethambutol) were responsible for the majority of resistance observed. A subset of the mutations identified in rpoB and katG were predicted to affect protein stability. Further, a strong direct correlation was observed between the minimum inhibitory concentration values and the distance of the mutated residues in the three-dimensional structures of rpoB and katG to their respective drugs binding sites. Conclusions Using the TDR resource, we demonstrate the usefulness of whole genome association and convergent evolution approaches to detect known and potentially novel mutations associated with drug resistance. Further, protein structural modelling could provide a means of predicting the impact of polymorphisms on drug efficacy in the absence of phenotypic data. These approaches could ultimately lead to novel

    1999-12-15

    In this reporting period the authors have continued their investigation of bimetallic nitride and carbide compounds for use in coprocessing of coal and waste plastics or rubber. Following up on their finding of a class of bimetallic nitrides, reported in the last period, they now report on a new family of bimetallic oxycarbides M{sup I}-M{sup II}-O-C (M{sup I} = Mo, W; M{sup II} = V, Nb, Cr, Fe, Co, Ni). They have carried out a preliminary test of the compounds with a model coal liquid feed and find that, in general, these carbides are even more active than the nitrides. They have identified Nb-Mo-O-C as the most promising catalyst, and this catalyst together with Mo{sub 2}C, the most active single-metal carbide are being investigated for the coprocessing reaction. Comparison is made to standard sulfide catalysts. The latter reaction is carried out in batch autoclave systems, so that preliminary tests are first carried out with a simpler five-component feedstock. The feedstock is a multi-component model mixture that simulates the combined feed of coal and waste materials. The idea is to use different compounds that are specific for each reaction type but have no overlapping products. The proposed design involves a 5-component mixture containing: 4-(1-naphthylmethyl)bibenzyl, abbreviated as NMBB, pyrene, tetradecane, dibenzothiophene and quinoline. NMBB simulates the aromatic-aliphatic as well as aliphatic-aliphatic C-C bonds in coal and in some aromatic plastics such as polystyrene. This compound has been used as a probe molecule in previous studies. Pyrene represents polyaromatic structures in coal, while tetradecane is representative of polyethylene-type plastics in chemical reactivity. Dibenzothiophene and quinoline provide sulfur and nitrogen content.

    2015-01-01

    This study used a qualitative design to explore parent mentors' summaries of conversations with more than 1,000 individual families of deaf and hard-of-hearing (DHH) children receiving parent-to-parent support as part of an existing family support project. Approximately 35% of the families were Spanish speaking. Five parent mentors who have DHH children provided varied support primarily via the telephone to families with DHH children, frequently birth to age 3. The nature and types of support provided were examined and resulted in an in-depth analysis of the summary notes prepared by the parent mentors. The notes were coded using a mixed-methods software application. Three topics were the most prevalent within the conversations between parent mentors and family members: hearing-related topics, early intervention, and multiple disabilities. Several differences emerged between English-speaking and Spanish-speaking families receiving support. Implications and the significance of this study are discussed. © The Author 2014.

    Maltose syrups have got wide-range utilizations in a variety of applications from bakery to drug-development. α-Amylases are among the most widely utilized industrial enzymes due to their high specificity in production of maltose syrup from starch. However, enzymes are not stable in ex vivo conditions towards alteration in pH, temperature, and such other parameters as high salt concentrations and impurities, where immobilization is required to advance the stability of the enzyme with which approach the requirement of isolation of the enzyme from media is eliminated as well. In this study, Termamyl® α-amylase was immobilized on the none-modified chitosan beads (NMCB), L-lysine-modified chitosan beads (LMCB), and L-asparagine-modified chitosan beads (AMCB) to assess effects of the support material on optimum conditions and kinetic parameters of the α-amylase activity in production of maltose from starch. Immobilization on NMCB, LMCB, and AMCB puts a strong influence on optimum pH, optimum temperature, stability, and kinetic parameters of α-amylase. Modification of chitosan beads with L-lysine and L-asparagine dramatically altered the overall immobilization yield, and enzyme's response to pH and temperature variations and the kinetic parameters. AMCB provided the best immobilization yield (49%), while LMCB only improved the yield by 2% from 22 to 24%.

    Full Text Available Purpose: The purpose of this pilot study was to describe parents’ perceived healthcare provider support for integrating technology, satisfaction with insulin pump use in their child with T1DM, and the relationship between parents’ perceived healthcare provider support and satisfaction with insulin pump use. Methods: A cross-sectional, correlational design was used to collect data for the present study. The study was conducted through an Internet survey among Mid-South parents who have a child with T1DM, 18 years old or younger using an insulin pump and/or continuous glucose monitoring (CGM. Frequencies, descriptive statistics, and correlation coefficients were calculated. Results: Most of the parents surveyed used an endocrinologist/pediatric endocrinologist as their primary diabetes healthcare provider and considered three to four healthcare professionals as part of the diabetes healthcare team who helped them utilize insulin pumps and advanced technologies. Parents (23.4% indicated a pharmacist was part of the healthcare team who helped them utilize technology. Parents appeared to perceive support for using insulin pumps; however, there is room for improvement. The more perceived support for integrating technology, the more satisfied the parents were with using insulin pumps (r=0.431, p=0.005. Conclusions: Results from this study suggest that parents and children need continued education, support and training to integrate insulin pumps into diabetes self-management. As more patients attempt to adopt insulin pumps and other advanced technologies, it will be important for pharmacists to support the adoption and integration of these technologies and be knowledgeable and helpful if asked about technology-related challenges.   Type: Student Project

  11. An exploration of how pre-service early childhood teachers use educative curriculum materials to support their science teaching practices

    Science.gov (United States)

    Englehart, Deirdre

    Research indicates that a proportion of elementary teachers are not comfortable teaching science to young children. These teachers are unaware of the best methods of approaching science and don't have the science background knowledge to support teaching through inquiry methods. This case study explores the role educative curriculum materials play in supporting pre-service early childhood education teachers' knowledge with science content and teaching practices. Specifically, I examine how educative materials impact pre-service teacher's content knowledge in science and their pedagogical content knowledge related to inquiry methods. Three pre-service early childhood teachers participated in this research. The teachers were initially interviewed about teaching science based upon three instruments: Views of Science Inquiry, Views of the Nature of Science and the Science Teachers Efficacy Beliefs Inventory. Each subject was observed teaching science in their internship site: the first lessons taught were guided or approved by their teachers and the next lessons were conducted using the support of educative curriculum materials. Finally, the initial instruments were once again administered along with an interview to obtain changes in teacher's knowledge, beliefs and understandings of science and science teaching. Results from this research indicate that educative curriculum was supportive of teachers in a variety of ways. Most importantly, this curriculum helped teachers to target more aspects of scientific inquiry during their science lessons than lessons without the use of educative curriculum. The important considerations regarding the effectiveness of the educative curriculum for these pre-service teachers were their underlying beliefs about how science should be taught, their uses of the curriculum materials and reflective practices regarding their own teaching. Results specifically related to early childhood educators include the level of inquiry implemented with

    Ce-Ti-O supports with different Ce/Ti molar ratios were synthesized by the solvothermal method using hexadecyltrimethylammonium bromide. Pt nanoparticles were then supported by photochemical deposition. The shape, size, and structure of these materials were analyzed by high-resolution transmission electron microscopy. The single CeO{sub 2} support was also prepared, consisting of agglomerated cubic particles ranging from {approx}3 to 8 nm. When titania was combined with ceria, a nanostructured architecture was produced, evidencing the strong influence of Ti in the support structure. Photodeposition of Pt nanoparticles is more efficient on Ce-Ti-O supports than in pristine CeO{sub 2}. Crystalline Pt nanoparticles (mainly of {approx}2 to 4 nm) were detected. The catalytic properties of the materials were tested in the selective hydrogenation of cinnamaldehyde to cinnamyl alcohol. It was observed that Pt supported on Ce-Ti-O is more active and selective than Pt on CeO{sub 2} or TiO{sub 2} separately. The catalyst with 40 mol% Ce leads to total conversion of cinnamaldehyde in a few minutes; however, higher selectivity toward the desired product (cinnamyl alcohol) was obtained with higher amounts of Ce (50 mol%).

    Geochemistry and materials studies are being performed in support of the Magma Energy Extraction Program. The work is largely restricted to: (1) characterizing magmatic environments at sites of interest, (2) testing engineering materials in laboratory simulated magmatic environments, (3) investigating chemical mass transport effects inherent in designs for direct contact heat exchangers, and (4) evaluating degassing hazards associated with drilling into and extracting energy from shallow magma. Magma characterization studies have been completed for shallow magma at Long Valley, Coso volcanic field, and Kilauea volcano. The behavior of 17 commercially available materials has been examined in rhyolite magma at 850/sup 0/C and 200 MPa for periods up to seven days. Analysis of reaction products from materials tests to date indicate that oxidation is the main corrosion problem for most alloys in rhyolitic magma. Considerations of corrosion resistance, high-temperature strength, and cost indicate nickel-base superalloys offer the most promise as candidates for use in rhyolitic magma.

    Wenrich, Marjorie D; Curtis, J Randall; Ambrozy, Donna A; Carline, Jan D; Shannon, Sarah E; Ramsey, Paul G

    2003-03-01

    This study addressed the emotional and personal needs of dying patients and the ways physicians help or hinder these needs. Twenty focus groups were held with 137 individuals, including patients with chronic and terminal illnesses, family members, health care workers, and physicians. Content analyses were performed based on grounded theory. Emotional support and personalization were 2 of the 12 domains identified as important in end-of-life care. Components of emotional support were compassion, responsiveness to emotional needs, maintaining hope and a positive attitude, and providing comfort through touch. Components of personalization were treating the whole person and not just the disease, making the patient feel unique and special, and considering the patient's social situation. Although the levels of emotional support and personalization varied, there was a minimal level, defined by compassion and treating the whole person and not just the disease, that physicians should strive to meet in caring for all dying patients. Participants also identified intermediate and advanced levels of physician behavior that provide emotional and personal support.

    2011-09-01

    Patient care handoffs are cognitively intense activities, especially on medical and surgical units where nurses synthesize information across an average of four to five patients every shift. The objective of this study was to examine handoffs and nurses' use of computerized patient summary reports in an electronic health record after computerized provider order entry (CPOE) was installed. We observed and audio taped 93 patient handoffs on 25 occasions on 5 acute care units in 2 different facilities sharing a vendor's electronic health record. We found that the computerized patient summary report and the electronic health record were minimally used during the handoff and that the existing patient summary reports did not provide adequate cognitive support for nurses. The patient summary reports were incomplete, rigid and did not offer "at a glance" information, or help nurses encode information. We make recommendations about a redesign of patient summary reports and technology to support the cognitive needs of nurses during handoffs at the change of shift.

    Health worker performance has been the focus of numerous interventions and evaluation studies in low- and middle-income countries. Few have examined changes in individual provider performance with an intervention encompassing post-training support contacts to improve their clinical practice and resolve programmatic problems. This paper reports the results of an intervention with 3471 abortion providers in India, Nepal and Nigeria. Following abortion care training, providers received in-person visits and virtual contacts by a clinical and programmatic support team for a 12-month period, designed to address their individual practice issues. The intervention also included technical assistance to and upgrades in facilities where the providers worked. Quantitative measures to assess provider performance were established, including: 1) Increase in service provision; 2) Consistent service provision; 3) Provision of high quality of care through use of World Health Organization-recommended uterine evacuation technologies, management of pain and provision of post-abortion contraception; and 4) Post-abortion contraception method mix. Descriptive univariate analysis was conducted, followed by examination of the bivariate relationships between all independent variables and the four dependent performance outcome variables by calculating unadjusted odds ratios, by country and overall. Finally, multivariate logistic regression was performed for each outcome. Providers received an average of 5.7 contacts. Sixty-two percent and 46% of providers met measures for consistent service provision and quality of care, respectively. Fewer providers achieved an increased number of services (24%). Forty-six percent provided an appropriate postabortion contraceptive mix to clients. Most providers met the quality components for use of WHO-recommended abortion methods and provision of pain management. Factors significantly associated with achievement of all measures were providers working in

    N-doped graphene has become an important support for Pd in both hydrogen storage and catalytic reactions. The molecular orbitals of carbon materials (including graphene, fullerene, and small carbon clusters) and those of the supported Pd species will hybrid much stronger as N dopants are introduced, owing to the increased electrostatic attraction at the interface. This enhances the carbon substrates' catching force for the supported Pd, preventing its leaching and aggregation in many practical applications. The better dispersion and stabilization of Pd nanoparticles, which are induced by various carbon supports with N-doping, are pleasing to us and could increase their efficiency and facilitate their recycling during various reaction processes in several fields.

    A superconductive load bearing support without a mechanical contact and vibration damping for cryogenic instruments in space is presented. The levitation support and vibration damping is accomplished by the use of superconducting magnets and the 'Meissner' effect. The assembly allows for transfer of vibration energy away from the cryogenic instrument which then can be damped by the use of either an electronic circuit or conventional vibration damping mean.

    To report the findings of a service review--specifically the strategy to provide early childhood services 'on site' at opioid treatment clinics to address access difficulties. Child and family health nurses are skilled in the assessment and support of families during early childhood. However, women with a history of substance abuse are often cautious when engaging with universal and other health services, with the result that the infant may miss recommended developmental screening and early referral to improve health outcomes. In 2006, an internal review was undertaken of the integration of early childhood and parenting services at opioid treatment clinics in a large Area Health Service of New South Wales, Australia. A qualitative study design, using semi-structured interview questions was used. Data were collected via six focus groups (4-15 participants in each group) and individual interview of child and family health nurses, nurse unit managers and clinical staff (n=58). Three key components of a model for providing early childhood support in collaboration with opioid treatment services were identified. First, the importance of building a trusting relationship between the woman and the child and family health nurses, second, maintaining continuity of care and a multidisciplinary/multiagency approach, and finally the importance of staff education, support and professional development. The provision of early childhood and parenting services on site, as part of a multidisciplinary 'one stop shop' approach to service delivery was a clear recommendation of the review. Reduction of access difficulties to specialised early childhood support is of benefit to clients, community health services attempting to provide a service to this difficult to reach population and to drug and alcohol services seeking to provide a high level of holistic care for clients. © 2012 Blackwell Publishing Ltd.

    The experiences of non-disabled children growing up with a sibling with an intellectual disability vary considerably, with reported impact ranging from increased mental health problems through evaluations of life enhancement. However, there is evidence that the net impact is neutral to positive, which was supported by the findings of this report of a service evaluation survey. The value of providing support to those young siblings is however clear. An established method of support is within a group of peers who also have a sibling with an intellectual disability, though no specific method for running this type of group has yet been fully explored. This article reports the views of 39 children taking part in such a group, analysing their perspective through a proposed model for the operation of sibling groups: social pedagogy. It was found that the closer the group's activities were to social pedagogy, the more supported the children and young people felt. © The Author(s) 2015.

    Diet-induced mating preference in Drosophila melanogaster results from amplification of the commensal bacterium Lactobacillus plantarum, providing a new role for gut microbiota and support for the hologenome concept of evolution. When the flies were treated with antibiotics prior to changing their diet, mating preference did not occur. These data also indicate that other potentially beneficial bacteria could be irreversibly lost by antibiotic treatment and that their replacement could provide a health benefit. We suggest that D. melanogaster can be a useful model organism to study the activities of gut microbiota and their interaction with the immune system.

  6. Supporting students' scientific explanations: A case study investigating the synergy focusing on a teacher's practices when providing instruction and using mobile devices

    Science.gov (United States)

    Delen, Ibrahim

    Engage students in constructing scientific practices is a critical component of science instruction. Therefore a number of researchers have developed software programs to help students and teachers in this hard task. The Zydeco group, designed a mobile application called Zydeco, which enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve students' scientific explanations, but these programs ignored how scientific explanation technologies can support teacher practices. Thus, to increase our knowledge how different scaffolds can work together, this study aimed to portray the synergy between a teacher's instructional practices (part 1) and using supports within a mobile devices (part 2) to support students in constructing explanations. Synergy can be thought of as generic and content-specific scaffolds working together to enable students to accomplish challenging tasks, such as creating explanations that they would not normally be able to do without the scaffolds working together. Providing instruction (part 1) focused on understanding how the teacher scaffolds students' initial understanding of the claim-evidence-reasoning (CER) framework. The second component of examining synergy (part 2: using mobile devices) investigated how this teacher used mobile devices to provide feedback when students created explanations. The synergy between providing instruction and using mobile devices was investigated by analyzing a middle school teacher's practices in two different units (plants and water quality). Next, this study focused on describing how the level of synergy influenced the quality of students' scientific explanations. Finally, I investigated the role of focused teaching intervention sessions to inform teacher in relation to students' performance. In

    Accurate characterization of entry capsule heat shield material properties is a critical component in modeling and simulating Thermal Protection System (TPS) response in a prescribed aerothermal environment. The thermal decomposition of the TPS material during the pyrolysis and charring processes is poorly characterized and typically results in large uncertainties in material properties as inputs for ablation models. These material property uncertainties contribute to large design margins on flight systems and cloud re- construction efforts for data collected during flight and ground testing, making revision to existing models for entry systems more challenging. The analysis presented in this work quantifies how material property uncertainties propagate through an ablation model and guides an experimental test regimen aimed at reducing these uncertainties and characterizing the dependencies between properties in the virgin and charred states for a Phenolic Impregnated Carbon Ablator (PICA) based TPS. A sensitivity analysis identifies how the high-fidelity model behaves in the expected flight environment, while a Monte Carlo based uncertainty propagation strategy is used to quantify the expected spread in the in-depth temperature response of the TPS. An examination of how perturbations to the input probability density functions affect output temperature statistics is accomplished using a Kriging response surface of the high-fidelity model. Simulations are based on capsule configuration and aerothermal environments expected during the Mars Science Laboratory (MSL) entry sequence. We identify and rank primary sources of uncertainty from material properties in a flight-relevant environment, show the dependence on spatial orientation and in-depth location on those uncertainty contributors, and quantify how sensitive the expected results are.

    2017-03-20

    Supporting self-management among people with long-term conditions is recognised as an important component of healthcare. Progressive neurological conditions (PNCs), for example, Parkinson's disease and multiple sclerosis are associated with problems such as fatigue and cognitive impairment which may make self-management more challenging. Health professionals may need to develop specific skills in order to provide effective self-management support for these patients. The review aims to develop explanatory theories about how health professional-targeted interventions to improve self-management support provision for people with PNCs operate in different circumstances. A realist synthesis of the evidence is proposed. There are 2 priority questions for the review to address. These relate to the role of a shared concept of self-management support within the healthcare team, and the need to tailor the support provided to the requirements of people with PNCs. Key stakeholders will be involved throughout the process. The initial search strategy uses terms relating to (1) self-management, (2) health professionals and (3) PNCs. Searching, data extraction and synthesis will occur in parallel. Studies will be prioritised for inclusion based on anticipated contribution to generating explanatory theories. Key informant interviews are planned to direct supplementary searches and help further refine the theories developed. Results will be expressed in the form of context-mechanism-outcome configurations. Publication guidelines on realist synthesis will be followed. The results will be published in a peer-reviewed journal and made available to organisations involved in the provision of health professional training. Published by the BMJ Publishing Group Limited.

    2004-10-01

    To perform a cost analysis for assessing options of reorganizing material supplies and reducing costs of the radiology division through the introduction of a materials management system. A materials management system (Piranha, Boston Scientific) was installed on an existing computer system. All consumables were inventoried and entered into the system. An ABC analysis determined further action. On the basis of order frequencies and availability requirements for emergencies, safety levels were agreed with physicians and other medical staff. Inventory costs were computed using these data. The interest rate for the capital tied up in the inventory was 8 % per year. The inventory showed that the capital tied up in stocks was euro 260,000 in 2001 and euro 190,000 in 2002. A change in supply strategy reduced inventory cost in 2001 and 2002. Annual interest expense was lowered by euro 18,420. Another saving of euro 2,700 was achieved by a reduction in storage cost. Annual inventory turnover totaled euro 298,000. The total cost cut through improved inventory management was euro 21,120 per year, which is equivalent to 7 % of the annual expenses. Adding the decline in the cost of shelf time overruns equal to 5 % of the annual expenses, the saving was approximately 12 % of total interventional radiology cost in 2001 and some 11 % in 2002. Flexible supply strategies and the introduction of a materials management program can help to reduce inventory costs in interventional radiology divisions without any impact on service levels.

    Finland has the operational capability to make airborne gamma ray measurements in emergency situations. The original purpose of airborne radiation mapping was to determine hazardous areas containing radioactive fallout after nuclear accidents or the use of nuclear weapons. Regular exercises are held annually to keep operational functionality at high level for this purpose. The knowledge and achieved practice can easily be extended to use in international radiation monitoring campaigns. The presented guidelines are based on Finnish knowhow, but it is not limited to use with Finnish equipment. The report describes the method and its usability in detecting the chain of nuclear material production using aerial gamma ray measurements. Technical details are given on how to manage measurement tasks, and information is also given on what is detectable from an aeroplane and how it is detected. The ability to use the airborne detection system has been tested to reveal the use of undeclared nuclear material. Various scenarios were considered with which to reveal clandestine nuclear material production, enrichment, and nuclear waste trails. The exercises arranged during this programme show that it is possible to reveal such clandestine activities. The fixed-wing gamma measurement technique developed under this contract is ready for detecting significant amounts of nuclear material efficiently and cost effectively. Large areas can be screened to find suspicious sub-areas for more accurate inspection. The approximate cost of screening is USD 17.4 per square kilometre. (orig.)

    Mobile health and patient-generated health data are promising health IT tools for delivering self-management support in diabetes, but little is known about provider perspectives on how best to integrate these programs into routine care. We explored provider perceptions of a patient-generated health data report from a text-message-based diabetes self-management program. The report was designed to relay clinically relevant data obtained from participants' responses to self-assessment questions delivered over text message. Likert-type scale response surveys and in-depth interviews were conducted with primary care physicians and endocrinologists who pilot tested the patient-generated health data report in an actual clinical encounter. Interview guides were designed to assess providers' perceptions of the feasibility and utility of patient-generated health data in routine clinical practice. Interviews were audiotaped, transcribed, and analyzed using the constant comparative method. Twelve providers successfully piloted the summary report in clinic. Although only a minority of providers felt the report changed the care they provided (3 of 12 or 25%), most were willing to use the summary report in a future clinical encounter (9 of 12 or 75%). Perceived benefits of patient-generated health data included agenda setting, assessment of self-care, and identification of patient barriers. Major themes discussed included patient selection, reliability of patient-generated health information, and integration into clinical workflow. Providers perceived multiple benefits of patient-generated health data in overcoming common barriers to self-management support in clinical practice and found the summary report feasible and usable in a clinical context. © 2014 Diabetes Technology Society.

  18. Assessing clinical support and inter-professional interactions among front-line primary care providers in remote communities in northern Canada: a pilot study

    2016-09-01

    Full Text Available Background: Primary care in remote communities in northern Canada is delivered primarily by nurses who receive clinical support from physicians in regional centres and the patient transportation system. To improve continuity, quality and access to care in remote northern communities, it is important to understand the perspectives of front-line providers and the complex challenges they face. Objective: To design and implement a survey of primary care providers to identify issues relating to inter-professional communication, clinical support and patient evacuation. Methods: In collaboration with the territorial government and regional health authority partners, we developed a 21-item self-administered questionnaire survey, which could be completed online. The survey was sent to 218 physicians and nurses who were employed in the Northwest Territories (NWT at the time of the survey and were involved in sending patients out of the community and/or receiving patients. The survey also contained an open-ended question at the end seeking comments regarding primary health care. Results: The overall low response rate of 39% among nurses and 19% among physicians threatens the validity of the quantitative results. The majority of providers were satisfied with their ability to communicate with other providers in a timely manner, their freedom to make clinical decisions and their overall experience practicing in the NWT. The patient transfer system appears to work from both the sender and receiver perspectives. However, a common theme reported by nurses was that physicians providing clinical advice, especially short-term locums, were not familiar with the local situation, whilst physicians at the receiving end remarked that the clinical information provided to them often lacked clarity. Conclusions: Important lessons were learnt from the pilot study, especially in better engagement of providers in planning and dissemination. The questionnaire design and the

    Given the shortage of skilled healthcare providers in Nigeria, frontline community health extension workers (CHEWs) are commonly tasked with providing maternal and child health services at primary health centers. In 2012, we introduced a mobile case management and decision support application in twenty primary health centers in northern Nigeria, and conducted a pre-test/post-test study to assess whether the introduction of the app had an effect on the quality of antenatal care services provided by this lower-level cadre. Using the CommCare mobile platform, the app dynamically guides CHEWs through antenatal care protocols and collects client data in real time. Thirteen health education audio clips are also embedded in the app for improving and standardizing client counseling. To detect changes in quality, we developed an evidence-based quality score consisting of 25 indicators, and conducted a total of 266 client exit interviews. We analyzed baseline and endline data to assess changes in the overall quality score as well as changes in the provision of key elements of antenatal care. Overall, the quality score increased from 13.3 at baseline to 17.2 at endline (peducation. These study results suggest that the introduction of a low-cost mobile case management and decision support application can spur behavior change and improve the quality of services provided by a lower level cadre of healthcare workers. Future research should employ a more rigorous experimental design to explore potential longer-term effects on client health outcomes.

    We performed a randomised, controlled, cross-over study of lung ventilation by Basic Life Support-trained providers using either the Tulip GT® airway or a facemask with a Guedel airway in 60 anaesthetised patients. Successful ventilation was achieved if the provider produced an end-tidal CO2 > 3.5 kPa and a tidal volume > 250 ml in two of the first three breaths, within 60 sec and within two attempts. Fifty-seven (95%) providers achieved successful ventilation using the Tulip GT compared with 35 (58%) using the facemask (p Tulip GT and facemask, the mean (SD) end-tidal CO2 was 5.0 (0.7) kPa vs 2.5 (1.5) kPa, tidal volume was 494 (175) ml vs 286 (186) ml and peak inspiratory pressure was 18.3 (3.4) cmH2 O vs 13.6 (7) cmH2 O respectively (all p Tulip GT airway. These results are similar to a previous manikin study using the same protocol, suggesting a close correlation between human and manikin studies for this airway device. We conclude that the Tulip GT should be considered as an adjunct to airway management both within and outside hospitals when ventilation is being undertaken by Basic Life Support-trained airway providers. © 2015 The Association of Anaesthetists of Great Britain and Ireland.

    In-depth qualitative interviews were conducted with healthcare providers (HCPs) from five HIV medical care coordination teams in a large Los Angeles County HIV clinic, including physicians, nurses, and psychosocial services providers. HCPs reported on the potential utility, acceptability, and barriers for patient self-monitoring and notifications via mobile phones, and web-based dashboards for HCPs. Potential benefits included: 1) enhancing patient engagement, motivation, adherence, and self-management; and 2) improving provider-patient relationships and HCP care coordination. Newly diagnosed and patients with co-morbidities were highest priorities for mobile application support. Facilitators included universal mobile phone ownership and use of smartphones or text messaging. Patient-level barriers included concerns about low motivation and financial instability for consistent use by some patients. Organizational barriers, cited primarily by physicians, included concerns about privacy protections, easy dashboard access, non-integrated electronic records, and competing burdens in limited appointment times. Psychosocial services providers were most supportive of the proposed mobile tools.

    To evaluate the effects of framework design and layering material on the fracture strength of implant-supported zirconia-based molar crowns. Sixty-six titanium abutments (GingiHue Post) were tightened onto dental implants (Implant Lab Analog). These abutment-implant complexes were randomly divided into three groups (n = 22) according to the design of the zirconia framework (Katana), namely, uniform-thickness (UNI), anatomic (ANA), and supported anatomic (SUP) designs. The specimens in each design group were further divided into two subgroups (n = 11): zirconia-based all-ceramic restorations (ZAC group) and zirconia-based restorations with an indirect composite material (Estenia C&B) layered onto the zirconia framework (ZIC group). All crowns were cemented on implant abutments, after which the specimens were tested for fracture resistance. The data were analyzed with the Kruskal-Wallis test and the Mann-Whitney U-test with the Bonferroni correction (α = 0.05). The following mean fracture strength values (kN) were obtained in UNI design, ANA design, and SUP design, respectively: Group ZAC, 3.78, 6.01, 6.50 and Group ZIC, 3.15, 5.65, 5.83. In both the ZAC and ZIC groups, fracture strength was significantly lower for the UNI design than the other two framework designs (P = 0.001). Fracture strength did not significantly differ (P > 0.420) between identical framework designs in the ZAC and ZIC groups. A framework design with standardized layer thickness and adequate support of veneer by zirconia frameworks, as in the ANA and SUP designs, increases fracture resistance in implant-supported zirconia-based restorations under conditions of chewing attrition. Indirect composite material and porcelain perform similarly as layering materials on zirconia frameworks. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Domestic violence (DV) is hazardous to survivors' health, from injuries sustained and from resultant chronic physical and mental health problems. Support from friends and relatives is significant in the lives of DV survivors; research shows associations between positive support and the health, well-being and safety of survivors. Little is known about how people close to survivors are impacted. The aim of this study was exploratory, with the following research question: what are the health and well-being impacts on adults who provide informal support to female DV survivors? A qualitative study using semistructured interviews conducted face to face, by telephone or using Skype. A thematic analysis of the narratives was carried out. Community-based, across the UK. People were eligible to take part if they had had a close relationship (either as friend, colleague or family member) with a woman who had experienced DV, and were aged 16 or over during the time they knew the survivor. Participants were recruited via posters in community venues, social media and radio advertisement. 23 participants were recruited and interviewed; the majority were women, most were white and ages ranged from mid-20s to 80. Generated themes included: negative impacts on psychological and emotional well-being of informal supporters, and related physical health impacts. Some psychological impacts were over a limited period; others were chronic and had the potential to be severe and enduring. The impacts described suggested that those providing informal support to survivors may be experiencing secondary traumatic stress as they journey alongside the survivor. Friends and relatives of DV survivors experience substantial impact on their own health and well-being. There are no direct services to support this group. These findings have practical and policy implications, so that the needs of informal supporters are legitimised and met. Published by the BMJ Publishing Group Limited. For permission to

    This report summarizes the experiments performed in FY17 on Gr. 91 steels. The testing of Gr. 91 has technical significance because, currently, it is the only approved material for Class A construction that is strongly cyclic softening. Specific FY17 testing includes the following activities for Gr. 91 steel. First, two types of key feature testing have been initiated, including two-bar thermal ratcheting and Simplified Model Testing (SMT). The goal is to qualify the Elastic – Perfectly Plastic (EPP) design methodologies and to support incorporation of these rules for Gr. 91 into the ASME Division 5 Code. The preliminary SMT test results show that Gr. 91 is most damaging when tested with compression hold mode under the SMT creep fatigue testing condition. Two-bar thermal ratcheting test results at a temperature range between 350 to 650o C were compared with the EPP strain limits code case evaluation, and the results show that the EPP strain limits code case is conservative. The material information obtained from these key feature tests can also be used to verify its material model. Second, to provide experimental data in support of the viscoplastic material model development at Argonne National Laboratory, selective tests were performed to evaluate the effect of cyclic softening on strain rate sensitivity and creep rates. The results show the prior cyclic loading history decreases the strain rate sensitivity and increases creep rates. In addition, isothermal cyclic stress-strain curves were generated at six different temperatures, and a nonisothermal thermomechanical testing was also performed to provide data to calibrate the viscoplastic material model.

    2017-07-01

    Full Text Available Material management in opencast mines is concerned with planning, organizing, and control of the flow of materials from their extraction points to destinations. It can be strongly affected by operational decisions that have to be made during the production process. To date, little research has focused on the application of simulation modeling as a powerful supportive tool for decision making in such systems. Practical experiences from implementing a simulation model of a mine for the operational support on an industrial scale are not known to the authors. This paper presents the extension of a developed stochastic simulation model by the authors from a conceptual stage (TRL4 to a new Technology Readiness Level (TRL 6 by implementing it in an industrially relevant environment. A framework for modeling, simulation, and validation of the simulation model applied to two large opencast lignite mines is presented in detail. Operational implementation issues, experiences, and challenges in practical applications are discussed. Furthermore, the strength of applying the simulation modeling as an operational decision support for material management in coal mining is demonstrated. Results of the case studies are used to describe the details of the framework, and to illustrate the strength and limitations of its application.

    2017-07-01

    Full Text Available Ethanol is a promising alternative source for fuel cells due to its low toxicity and high power density. However, the cleavage of the C-C bond, CO poisoning, and low electrocatalyst stability are still considered crucial issues. To overcome this limitation, binary, ternary and quaternary electrocatalysts have been investigated along with new carbon supports. This paper presents a physicochemical and electrochemical investigation of quaternary PtSnNiGa/C electrocatalysts supported on Vulcan XC72 and Printex-L6 carbons and also a carbon produced by natural gas pyrolysis in an Argon plasma torch (Black Plasma. The electrochemical characterization was performed through cyclic voltammetry, chronoamperometry, chronopotentiometry and electrochemical impedance spectroscopy in the presence of ethanol 1.0 mol L-1. Energy dispersive X-ray spectroscopy, X-ray diffraction, Raman spectroscopy and transmission electron microscopy were also carried out for physicochemical characterization. The electrochemical results show that the quaternary electrocatalysts supported on Vulcan XC72 and Printex-L6 carbons display a high current normalized by Pt mass and are more stable than the electrocatalyst supported on Black Plasma. In addition, the quaternary electrocatalysts with reduced Pt loading display better electrocatalytic activity towards the EOR compared to high Pt loading electrocatalysts. DOI: http://dx.doi.org/10.17807/orbital.v9i3.949

    Full Text Available Ce-modified mesoporous silica materials MCM-41 and SBA-15, namely 32 wt % Ce–Si–MCM-41, 16 wt % Ce–H–MCM-41 and 20 wt % Ce–Si–SBA-15, were prepared, characterized and studied in the selective preparation of trans-carveol by α-pinene oxide isomerization. The characterizations of these catalysts were performed using scanning electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption and FTIR pyridine adsorption. Selective preparation of trans-carveol was carried out in the liquid phase in a batch reactor. The activity and the selectivity of catalyst were observed to be influenced by their acidity, basicity and morphology of the mesoporous materials. The formation of trans-carveol is moreover strongly influenced by the basicity of the used solvent and in order to achieve high yields of this desired alcohol it is necessary to use polar basic solvent.

    To address safety issues regarding effective waste management efforts of underground organic waste storage tanks at the Hanford Site, the Bureau of Mines conducted a series of tests, at the request of the Westinghouse Hanford company. In this battery of tests, the thermal and explosive characteristics of surrogate materials, chosen by Hanford, were determined. The surrogate materials were mixtures of inorganic and organic sodium salts, representing fuels and oxidants. The oxidants were sodium nitrate and sodium nitrite. The fuels were sodium salts of oxalate, citrate and ethylenediamine tetraacetic acid (EDTA). Polyethylene powder was also used as a fuel with the oxidant(s). Sodium aluminate was used as a diluent. In addition, a sample of FeCN, supplied by Hanford was also investigated.

    There were designed and synthesized naphthalene and pyrene derivatives consisting of fluorophore group and of receptor fragment with donor N and O atoms. These fluorosensors were covalently attached by grafting carboxyl group to surfaces of silica xerogel or mesoporous silicas (MCM-41 and MCM-48) functionalized either with 3-aminopropyl or 3-glycidoxypropyl groups. The pyrene derivatives 2 and 3 covalently grafted on MCM-48 silica functionalized with 3-aminopropyl groups are potential recognition elements of a fluorescence chemical sensor. Fluorescence emission of the prepared recognition materials is quenched specifically owing to photoinduced electron transfer (PET) effect after coordination reactions with Cu(II) ions. Moreover, both the materials exhibit selectivity for Cu(II) ions in aqueous solutions in presence of such metal ions as: alkali, alkaline earth and transition. During UV irradiation the studied recognition elements undergo slowly photochemical degradation.

    The VHTR reference concept is a helium-cooled, graphite moderated, thermal neutron spectrum reactor with an outlet temperature of 1000 C or higher. It is expected that the VHTR will be purchased in the future as either an electricity producing plant with a direct cycle gas turbine or a hydrogen producing (or other process heat application) plant. The process heat version of the VHTR will require that an intermediate heat exchanger (IHX) and primary gas circulator be located in an adjoining power conversion vessel. A third VHTR mission - actinide burning - can be accomplished with either the hydrogen-production or gas turbine designs. The first ''demonstration'' VHTR will produce both electricity and hydrogen using the IHX to transfer the heat to either a hydrogen production plant or the gas turbine. The plant size, reactor thermal power, and core configuration will be designed to assure passive decay heat removal without fuel damage during accidents. The fuel cycle will be a once-through very high burnup low-enriched uranium fuel cycle. The purpose of this report is to identify the materials research and development needs for the VHTR. To do this, we focused on the plant design described in Section 2, which is similar to the GT-MHR plant design (850 C core outlet temperature). For system or component designs that present significant material challenges (or far greater expense) there may be some viable design alternatives or options that can reduce development needs or allow use of available (cheaper) materials. Nevertheless, we were not able to assess those alternatives in the time allotted for this report and, to move forward with this material research and development assessment, the authors of this report felt that it was necessary to use a GT-MHR type design as the baseline design.

    Systematic reviews of behaviour change interventions for smoking cessation vary in scope, quality, and applicability. The current review aims to generate more accurate and useful findings by (1) a detailed analysis of intervention elements that change behaviour (i.e. behaviour change techniques (BCTs)) and potential moderators of behaviour change (i.e. other intervention and sample characteristics) and (2) assessing and controlling for variability in support provided to comparison groups in smoking cessation trials. A systematic review will be conducted of randomized controlled trials of behaviour change interventions for smoking cessation in adults (with or without pharmacological support), with a minimum follow-up of 6 months, published after 1995. Eligible articles will be identified through the Cochrane Tobacco Addiction Group Specialized Register. Study authors will be asked for detailed descriptions of smoking cessation support provided to intervention and comparison groups. All data will be independently coded by two researchers. The BCT taxonomy v1 (tailored to smoking cessation interventions) and template for intervention description and replication criteria will be used to code intervention characteristics. Data collection will further include sample and trial characteristics and outcome data (smoking cessation rates). Multilevel mixed-effects meta-regression models will be used to examine which BCTs and/or BCT clusters delivered to intervention and comparison groups explain smoking cessation rates in treatment arms (and effect sizes) and what key moderators of behaviour change are. Predicted effect sizes of each intervention will be computed assuming all interventions are compared against comparison groups receiving the same levels of behavioural support (i.e. low, medium, and high levels). Multi-disciplinary advisory board members (policymakers, health care providers, and (ex-)smokers) will provide strategic input throughout the project to ensure the

    To establish the rationale for using a lecturer as a visiting tutor, and to identify the activities undertaken during clinical placements to support student learning and assessment in practice. A secure electronic survey was used to incorporate qualitative and quantitative data collection procedures. Thirty-three higher education institution (HEI) providers of physiotherapy education in the UK, registered with the Chartered Society of Physiotherapy. UK HEI physiotherapy placement coordinators. A questionnaire was used to examine HEI perceptions. A pilot focus group consultation informed the questionnaire content. Surveys were analysed based on the proportion of responses to closed questions on an adapted Likert scale, with further thematic analysis of open questions. All 25 respondents (25/33, 76%) indicated their provision of support for students and clinical educators throughout their clinical placements. 'Face-to-face' engagement during the placement visit was viewed as essential to guide the clinical educator to provide a consistent approach to learning and assessment strategies; ensuring cohesion between theoretical and clinical components of the curriculum was viewed as a core objective by visiting academic tutors. However, the emergent themes highlighted key differences between HEIs' perspectives of what this support for clinical placement learning should entail. The majority of HEIs endorse the use of a lecturer as a visiting tutor to inform and maintain the standard of learning and assessment within the clinical placement. However, the value of this interaction requires confirmation via other stakeholders, and exploration of other forms of non-face-to-face support processes warrant further investigation.

    Full Text Available Large variations in network Quality of Service (QoS such as bandwidth, latency, jitter, and reliability may occur during media transfer over vehicular ad hoc networks (VANET. Usage of VANET over mobile and wireless computing applications experience “bursty” QoS behavior during the execution over distributed network scenarios. Applications such as streaming media services need to adapt their functionalities to any change in network status. Moreover, an enhanced software platform is necessary to provide adaptive network management services to upper software components. HOSA, a handoff service broker based architecture for QoS adaptation over VANET supports in providing awareness. HOSA is structured as a middleware platform both to provide QoS awareness to streaming applications as well to manage dynamic ad hoc network resources with support over handoff in an adaptive fashion. HOSA is well analyzed over routing schemes such as TIBSCRPH, SIP and ABSRP where performance of HOSA was measured using throughput, traffic intensity and end to end delay. HOSA has been analyzed using JXTA development toolkit over C++ implemented classes to demonstrate its performance over varying node mobility established using vehicular mobility based conference application.

    Sandra Haider

    Full Text Available The aim of the study was to compare the effects of home visits with physical training and nutritional support on inflammatory parameters to home visits with social support alone within a randomized controlled trial. Prefrail and frail persons received home visits from lay volunteers twice a week for 12 weeks. Participants in the physical training and nutritional intervention group (PTN, n = 35 conducted two sets of six strength exercises and received nutritional support. The social support group (SoSu, n = 23 received visits only. TNF-α, IL-6, CRP, and total leukocyte count were assessed at baseline and after 12 weeks. Changes over time within groups were analyzed with paired t-tests; differences between groups were analyzed with ANCOVA for repeated measurements. In the PTN group, IL-6 and CRP remained stable, whereas in the SoSu group, IL-6 increased significantly from a median value of 2.6 pg/l (min-max = 2.0-10.2 to 3.0 pg/l (min-max = 2.0-20.8, and CRP rose from 0.2 mg/dl (min-max = 0.1-0.9 to 0.3 mg/dl (min-max = 0.1-3.0 after 12 weeks. In CRP, a significant difference between groups was found. TNF-α and total leukocyte count did not change in either the PTN group or the SoSu group. Persons showing an increase in physical performance (OR 4.54; 95% CI = 1.33-15.45 were more likely to have constant or decreased IL-6 values than persons who showed no improvement. In conclusion, in non-robust older adults, a physical training and nutritional support program provided by lay volunteers can delay a further increase in some inflammatory parameters.

  20. Assessment of the quality of antenatal care services provided by health workers using a mobile phone decision support application in northern Nigeria: a pre/post-intervention study.

    Marion McNabb

    Full Text Available Given the shortage of skilled healthcare providers in Nigeria, frontline community health extension workers (CHEWs are commonly tasked with providing maternal and child health services at primary health centers. In 2012, we introduced a mobile case management and decision support application in twenty primary health centers in northern Nigeria, and conducted a pre-test/post-test study to assess whether the introduction of the app had an effect on the quality of antenatal care services provided by this lower-level cadre.Using the CommCare mobile platform, the app dynamically guides CHEWs through antenatal care protocols and collects client data in real time. Thirteen health education audio clips are also embedded in the app for improving and standardizing client counseling. To detect changes in quality, we developed an evidence-based quality score consisting of 25 indicators, and conducted a total of 266 client exit interviews. We analyzed baseline and endline data to assess changes in the overall quality score as well as changes in the provision of key elements of antenatal care.Overall, the quality score increased from 13.3 at baseline to 17.2 at endline (p<0.0001, out of a total possible score of 25, with the most significant improvements related to health counseling, technical services provided, and quality of health education.These study results suggest that the introduction of a low-cost mobile case management and decision support application can spur behavior change and improve the quality of services provided by a lower level cadre of healthcare workers. Future research should employ a more rigorous experimental design to explore potential longer-term effects on client health outcomes.

    Full Text Available TiO2 nanoparticles were immobilized on two porous materials used as catalyst supports, namely, activated carbon (AC and natural clay (NC, through an impregnation process using TiO2 (P25 as precursor. The so-prepared composite materials were characterized by X-ray diffraction (XRD, scanning electron microscopy (SEM, transition electron microscopy (TEM, and nitrogen physisorption, that is, Brunauer-Emmett-Teller (BET surface area determination. SEM and TEM observation evidenced that TiO2 was deposited on AC and NC surface. XRD results confirmed that TiO2 existed in a mixture of anatase and rutile phases. The specific surface area of photocatalysts decreased drastically in comparison with the original materials. The photocatalytic activity of these materials was assayed in the oxidation of Methyl Green (MG dye in aqueous medium under UV irradiation. TiO2/AC exhibited higher photocatalytic oxidation activity than TiO2 at neutral pH. Total mineralization of MG was confirmed by means of COD analysis, pointing to these materials as an efficient, cost-effective, and environment friendly alternative for water treatment.

    Full Text Available Introduction: In the present study, the finite element method (FEM was used to investigate the effects of prosthesis material types on stress distribution of the bone surrounding implants and to evaluate stress distribution in three-unit implant-supported fixed dental prosthesis (FDP. Materials and Methods: A three-dimensional (3D finite element FDP model of the maxillary second premolar to the second molar was designed. Three load conditions were statically applied on the functional cusps in horizontal (57.0 N, vertical (200.0 N, and oblique (400.0 N, θ = 120° directions. Four standard framework materials were evaluated: Polymethyl methacrylate (PMMA, base-metal, porcelain fused to metal, andporcelain. Results: The maximum of von Mises stress in the oblique direction was higher than the vertical and horizontal directions in all conditions. In the bone-crestal section, the maximum von Mises stress (53.78 MPa was observed in PMMA within oblique load. In FDPs, the maximum stress was generated at the connector region in all conditions. Conclusion: A noticeable difference was not observed in the bone stress distribution pattern with different prosthetic materials. Although, higher stress value could be seen in polymethyl methacrylate, all types of prosthesis yielded the same stress distribution pattern in FDP. More clinical studies are needed to evaluate the survival rate of these materials.

    Bio-hydrogen production from sugarcane vinasse in anaerobic up-flow packed-bed reactors (APBR) was evaluated. Four types of support materials, expanded clay (EC), charcoal (Ch), porous ceramic (PC), and low-density polyethylene (LDP) were tested as support for biomass attachment. APBR (working volume - 2.3 L) were operated in parallel at a hydraulic retention time of 24 h, an organic loading rate of 36.2 kg-COD m(-3) d(-1), at 25 °C. Maximum volumetric hydrogen production values of 509.5, 404, 81.4 and 10.3 mL-H2 d(-1) L(-1)reactor and maximum yields of 3.2, 2.6, 0.4 and 0.05 mol-H2 mol(-1) carbohydrates total, were observed during the monitoring of the reactors filled with LDP, EC, Ch and PC, respectively. Thus, indicating the strong influence of the support material on H2 production. LDP was the most appropriate material for hydrogen production among the materials evaluated. 16S rRNA gene by Terminal Restriction Fragment Length Polymorphism (T-RFLP) analysis and scanning electron microscopy confirmed the selection of different microbial populations. 454-pyrosequencing performed on samples from APBR filled with LDP revealed the presence of hydrogen-producing organisms (Clostridium and Pectinatus), lactic acid bacteria and non-fermentative organisms.

    Full Text Available Objectives: Fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (CHS. The purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (FPDs with excessive crown height, fabricated from three different materials.Materials and Methods: Two implants with corresponding abutments were mounted in a metal model that simulated mandibular second premolar and second molar. Thirty 3-unit frameworks with supportive anatomical design were fabricated using zirconia, nickel-chromium alloy (Ni-Cr, and polyetheretherketone (PEEK (n=10. After veneering, the CHS was equal to 15mm. Then; samples were axially loaded on the center of pontics until fracture in a universal testing machine at a crosshead speed of 0.5 mm/minute. The failure load data were analyzed by one-way ANOVA and Games-Howell tests at significance level of 0.05.Results: The mean failure loads for zirconia, Ni-Cr and PEEK restorations were 2086±362N, 5591±1200N and 1430±262N, respectively. There were significant differences in the mean failure loads of the three groups (P<0.001. The fracture modes in zirconia, metal ceramic and PEEK restorations were cohesive, mixed and adhesive type, respectively.Conclusions: According to the findings of this study, all implant supported three-unit FPDs fabricated of zirconia, metal ceramic and PEEK materials are capable to withstand bite force (even para-functions in the molar region with excessive CHS.Keywords: Dental Implants; Polyetheretherketone; Zirconium oxide; Dental Restoration Failure; Dental Porcelain

    The effect of nickel (Ni) load (0, 5 and 10 wt.%) and support material (Ce{sub 0.9}La{sub 0.1}O{sub 2}, Ce{sub 0.9}Zr{sub 0.1}O{sub 2} and {gamma}-Al{sub 2}O{sub 3}), together the amount of oxygen ({lambda} = 0.25 and {lambda} = 0.5) and gas hourly space velocity (50 000, 100 000 and 150 000 h{sup -1}) were investigated for the selective catalytic oxidation of ammonia in gasified biomass. The mixed metal oxide support materials were prepared by microemulsion, whereas the alumina was a commercial product. Ni was added to the different supports by incipient wetness. All the obtained catalysts were characterised by BET and XRD analysis. Cordierite monoliths coated with 20 wt.% catalytic material were tested in a tubular quartz reactor. For simulating the gasified biomass fuel, 500 ppm of NH{sub 3} was added to the fuel. Water was also present during the activity tests, which were carried out between 500 and 750 C. The results from the activity tests at {lambda} = 0.25 and gas hourly space velocity of 100 000 h{sup -1} indicated that the 10 wt.% Ni on Ce{sub 0.9}La{sub 0.1}O{sub 2} was the best catalyst obtaining 65 and 97% N{sub 2} yield at 500 and 750 C, respectively. By increasing {lambda} to 0.5 and decreasing the gas hourly space velocity, the N{sub 2} yield improved considerably at low temperature level (500 C). Moreover, NO{sub x} emissions maintained at low levels depending on the experimental conditions. Constant conversion and negligible carbon deposition were also two other important observations from the mixed metal oxide supported catalysts. On the contrary, all the alumina-based catalysts displayed the lowest performance. (author)

    It is important to support women to exclusively breastfeed for 6 months and continue breastfeeding for 24 months and beyond. It is also necessary to provide the poor with access to affordable ways to improve the quality of complementary foods. Currently, many countries do not have the legal and policy environment necessary to support exclusive and continued breastfeeding. Legislative and policy changes are also necessary for introducing complementary food supplements, allowing them to be marketed to those who need them, and ensuring that marketing remains appropriate and in full compliance with the International Code of Marketing of Breastmilk Substitutes. This paper aims to illustrate the above with examples from Indonesia and to identify legislative requirements for supporting breastfeeding and enabling appropriate access to high-quality complementary food supplements for children 6-24 months of age. Requirements include improved information, training, monitoring and enforcement systems for the International Code of Marketing of Breastmilk Substitutes; implementation and monitoring of the Baby-Friendly Hospital Initiative; establishment of a registration category for complementary food supplements to enhance availability of high-quality, low-cost fortified products to help improve young child feeding; clear identification and marketing of these products as complementary food supplements for 6-24-month-olds so as to promote proper use and not interfere with breastfeeding. © 2011 Blackwell Publishing Ltd.

    Healthcare provider (HCP) activities and attitudes towards patients strongly influence medication adherence. The aim of this study was to assess current clinical practices to support patients in adhering to treatment with oral anticancer agents (OACA) and to explore clues to improve the management of medication adherence. A cross-sectional, observational study among HCPs in (haemato-)oncology settings in Belgium and the Netherlands was conducted in 2014 using a composite questionnaire. A total of 47 care activities were listed and categorised into eight domains. HCPs were also asked about their perceptions of adherence management on the items: insight into adherence, patients' communication, capability to influence, knowledge of consequences and insight into causes. Validated questionnaires were used to assess beliefs about medication (BMQ) and shared decision making (SDM-Q-doc). In total, 208 HCPs (29% male) participated; 107 from 51 Dutch and 101 from 26 Belgian hospitals. Though a wide range of activities were reported, certain domains concerning medication adherence management received less attention. Activities related to patient knowledge and adverse event management were reported most frequently, whereas activities aimed at patient's self-efficacy and medication adherence during ongoing use were frequently missed. The care provided differed between professions and by country. Belgian physicians reported more activities than Dutch physicians, whereas Dutch nurses and pharmacists reported more activities than Belgian colleagues. The perceptions of medication adherence management were related to the level of care provided by HCPs. SDM and BMQ outcomes were not related to the care provided. Enhancing the awareness and perceptions of medication adherence management of HCPs is likely to have a positive effect on care quality. Care can be improved by addressing medication adherence more directly e.g., by questioning patients about (expected) barriers and discussing

    2007-03-01

    Full Text Available  In this paper forced vibration of the beam due to bonded piezoelectric patch is considered. When an external excitation is applied to the beam, it starts to vibrate, and the resulting acoustic response is predicted from the analytical model, which is based on Bernoulli-Euler theory of beam vibration. Analytical research of the sound radiation by a finite elastic beam is done for criteria based on minimal total sound power level. Helmholtz equation and inhomogeneous differential equation for beam transverse motion defines the solution to this problem. Such solutions were found for boundary conditions of simply supported and cantilever beams. In order to solve the task two analytical methods were used for simply supported beam. The solutions received by Fourier transform and Green functions approach give the very similar results, thus, proving methods reliability. At the case studies the exerted voltage, phase, location and piezoelectric actuator length are varied in order to establish their influence on noise attenuation.

    Full Text Available Today energy conservation is a very important issue in the world and Turkey. The aim of this study is to minimize the heat abduction, thus to save energy by utilizing the factors to prevent the heat abduction on the walls of buildings. First of all, a back-propagation network model with artificial neural network model was used for the factors that can cause heat loss on the walls. Whether the walls have insulation were considered. After that, Decision Support Systems were used for heat insulation to select the appropriate materials. A Decision Support Model with Analytic Hierarchy Process (AHP was recommended to meet the needs of a customer best and to make better decisions for the selection of the materials. The method was used by construction firms for their decision processes for the best materials and the results were evaluated. After the evaluations were done, the factors that cause heat loss were considered and it became clear which factors were more important for the prevention of heat loss.

    A novel system for low-temperature alcoholic fermentation of glucose is described. This system consists of kefir yeast immobilized on delignified cellulosic materials. Batch fermentations were carried out at various pH values, and the effect of temperature on kinetic parameters, in the range of 5-30 degrees C, was examined. At pH 4.7 the shortest fermentation time was obtained. The formation of volatiles indicates that the concentration of amyl alcohols (total content of 2-methylbutanol-1 and 3-methylbutanol-1) is reduced as the temperature becomes lower. Propanol-1 and isobutyl alcohol formation drops significantly below 15 degrees C. The percentage of ethyl acetate increases as the temperature is diminished. At 5 degrees C the content of total volatiles in the product was only 38% of the volatiles formed during fermentation at 30 degrees C.

    2017-03-01

    Magnetism and its various applications are essential for our daily life and for many technological developments. The term magnetism is almost always used as a synonym for ferromagnetism. However, the magnetic properties of the elements of the periodic table indicate that the vast majority of elements are not ferromagnetic, but rather, diamagnetic or paramagnetic. Typically, only ferromagnetism is discussed in classrooms, which can create a distorted picture. This article supplies the further development of an experiment demonstrating the dia- and paramagnetic properties with an electronic balance and a neodymium magnet. It focuses on an investigation of ordinary materials that occur in pupils' everyday environment. The experiment is applicable both for a quantitative measurement of the magnetic (volume) susceptibility χV and can serve as a phenomenological approach to dia- and paramagnetism. Moreover, it encourages a discussion about typical beliefs regarding the nature of science, comparing the behavior of common objects in weak and in strong magnetic fields.

    The work reported here is an investigation of the sensitivity of component temperatures of a storage system, including fuel cladding temperatures, in response to age-related changes that could degrade the design-basis thermal behavior of the system. The purpose of these sensitivity studies is to provide a realistic example of how changes in the physical properties or configuration of the storage system components can affect temperatures and temperature distributions. The magnitudes of these sensitivities can provide guidance for identifying appropriate modeling assumptions for thermal evaluations extending long term storage out beyond 50, 100, 200, and 300 years.

    Clinical management of comorbidities is a challenge, especially in a clinical decision support setting, as it requires the safe and efficient reconciliation of multiple disease-specific clinical procedures to formulate a comorbid therapeutic plan that is both effective and safe for the patient. In this paper we pursue the integration of multiple disease-specific Clinical Practice Guidelines (CPG) in order to manage co-morbidities within a computerized Clinical Decision Support System (CDSS). We present a CPG integration framework-termed as COMET (Comorbidity Ontological Modeling & ExecuTion) that manifests a knowledge management approach to model, computerize and integrate multiple CPG to yield a comorbid CPG knowledge model that upon execution can provide evidence-based recommendations for handling comorbid patients. COMET exploits semantic web technologies to achieve (a) CPG knowledge synthesis to translate a paper-based CPG to disease-specific clinical pathways (CP) that include specialized co-morbidity management procedures based on input from domain experts; (b) CPG knowledge modeling to computerize the disease-specific CP using a Comorbidity CPG ontology; (c) CPG knowledge integration by aligning multiple ontologically-modeled CP to develop a unified comorbid CPG knowledge model; and (e) CPG knowledge execution using reasoning engines to derive CPG-mediated recommendations for managing patients with comorbidities. We present a web-accessible COMET CDSS that provides family physicians with CPG-mediated comorbidity decision support to manage Atrial Fibrillation and Chronic Heart Failure. We present our qualitative and quantitative analysis of the knowledge content and usability of COMET CDSS.

    Heteropoly acid H4SiW12O40 (SiW) has been supported on different nanoporous materials and characterized by powder X-ray diffraction (XRD), FTIR, HRTEM, N2 physisorption, and thermal analysis. No SiW diffraction peaks are observed after loading 33-50 wt% of SiW on various mesoporous materials (pore size: -30 Å) except for siliceous MCM-48. In contrast, the SiW diffraction peaks appear at 14 wt% loading on zeolite EMT with micropore size of ca. 7.4 x 6.5 Å. Supported SiW retains the Keggin structure on mesopore surface. The cubic mesostructure of MCM-48 is stable while MCM-41 loses its regular hexagonal mesostructure upon loading SiW. Several factors account for different behaviours of various supports, including pore size, curvature of mesopore interface and interaction between SiW and aluminium sites in the framework. The resulting 33-50 wt% SiW/MCM-48 solid acid catalysts have large surface area (- 550 m2/g), regular pore arrangement with uniform pore size (- 25 Å), finely dispersed SiW and good thermal stability. They exhibit significantly improved activity in acid-catalyzed cracking of long-chain hydrocarbons in comparison with bulk SiW and SiW/MCM-41.

    2009-01-01

    A phase change material (PCM) heat sink using super cooled ice as a nontoxic, nonflammable PCM is being developed. The latent heat of fusion for water is approximately 70% larger than most paraffin waxes, which can provide significant mass savings. Further mass reduction is accomplished by super cooling the ice significantly below its freezing temperature for additional sensible heat storage. Expansion and contraction of the water as it freezes and melts is accommodated with the use of flexible bag and foam materials. A demonstrator unit has been designed, built, and tested to demonstrate proof of concept. Both testing and modeling results are presented along with recommendations for further development of this technology.

    Skin-like temperature- and pressure-sensing capabilities are essential features for the next generation of artificial intelligent products. Previous studies of e-skin and smart elements have focused on flexible pressure sensors, whereas the simultaneous and sensitive detection of temperature and pressure with a single device remains a challenge. Here we report developing flexible dual-parameter temperature-pressure sensors based on microstructure-frame-supported organic thermoelectric (MFSOTE) materials. The effective transduction of temperature and pressure stimuli into two independent electrical signals permits the instantaneous sensing of temperature and pressure with an accurate temperature resolution of sensors can be self-powered with outstanding sensing performance. The excellent sensing properties of MFSOTE-based devices, together with their unique advantages of low cost and large-area fabrication, make MFSOTE materials possess promising applications in e-skin and health-monitoring elements.

    The NNSA Material Protection, Control, and Accounting (MPC&A) program has been engaged for fifteen years in upgrading the security of nuclear materials in Russia. Part of the effort has been to establish the conditions necessary to ensure the long-term sustainability of nuclear security. A sustainable program of nuclear security requires the creation of an indigenous infrastructure, starting with sustained high level government commitment. This includes organizational development, training, maintenance, regulations, inspections, and a strong nuclear security culture. The provision of modern physical protection, control, and accounting equipment to the Russian Federation alone is not sufficient. Comprehensive infrastructure projects support the Russian Federation's ability to maintain the risk reduction achieved through upgrades to the equipment. To illustrate the contributions to security, and challenges of implementation, this paper discusses the history and next steps for an indigenous Tamper Indication Device (TID) program, and a Radiation Portal Monitoring (RPM) program.

    The aim of this work is to show the characterization of pre hispanic paintings mainly of the materials that support the pigments. The samples come from three different archaeological sites, Palenque-Chiapas (two specimens), Teotihuacan-Estado de Mexico (one specimen) and Mitla-Oaxaca (one specimen); Mayan, Teotihuacan and Mixtec-Zapotec culture respectively. The samples were analyzed by Sem, EDS, Tem, XRD and IR. The results show calcite as common phase for all the samples, however exist other phases identified depending on the site as dolomite, ankerite, calcium silicon chloride, etc. The origin of the red color of the analyzed pigments were cinnabar (HgS) by a sample of Palenque and hematite (Fe{sub 2}O{sub 3}) by the other specimen, this last crystalline phase also present in the Mitla and Teotihuacan samples. By IR were identified some organic compounds in all the samples, but not copal. (Author)

    Full Text Available A pilot aerobic horizontal plug flow reactor filled with pieces of PET (polyethylene terephthalate, from plastic bottles was installed for treatment of a synthetic substrate prepared from lactic whey with COD values of 800 to 2100 mg/L. A bacterial inoculum previously acclimated to the substrate was used. Organic material removal efficiencies of 62.2%, 85% y 94% were obtained with retention times of 5.14, 6.01 and 8.01 hours, and with volumetric organic loads (Lv of 7.68, 6.19 and 4.61 kg/day.m3, respectively. Also, the kinetic mass transfer constant (k was calculated and it presented a value of 0.02 m/day. On the other hand, an F/M ratio of 0.4 was determined, indicating that the process had a similar performance to an extended aeration system. Finally, the biomass generated inside the reactor was analyzed, obtaining a value of 11560 mg /L, which is a higher value than those of conventional systems.

    Full Text Available Emulation has been widely discussed as a preservation strategy for digital documents that depend upon proprietary executables, as well as for legacy programs. The fundamental assumption of this strategy is that an artifact (document or program will be bundled with any required contemporaneous software in an archival information package (AIP which can be loaded and executed in an emulation environment by patrons wishing to access the preserved artifact, yet little has been written about how to identify the required components for such an AIP. Even where a digital document was distributed with a binary viewer, there may be dependencies on other software libraries. In this paper we discuss a pilot study that performed dependency analysis for digital materials originally distributed on CD-ROM. In particular, we show how to utilize a small number of existing off-the-shelf libraries to build a tool that can analyze executables within ISO (CD-ROM images, and then examine the results of applying this tool to a body of archived images.

    2016-06-01

    As there is a growing interest in conducting human missions to Mars, the need for suitable life support systems becomes more and more important. The reliability of such systems has to increase with the duration of manned missions. Furthermore the maintenance requirements have to be low in order to ensure their efficient use over a long period of time. A proposal for a hybrid life support system that is based on plasma technology for the creation of oxygen from the dissociation of carbon dioxide is given in this paper. The main focus lies on geometrical considerations regarding the optimal shape of the main reactor chamber as well as on suitable materials, which are most promising for the construction of such a system.

    Eight urethane compounds were evaluated as possible replacement for the existing encapsulating compoounds for electrical cables for the Launch Support System at Kennedy Space Center (KSC). The existing encapsulating compound, PR-1535, contains the curative MOCA 4-4'-Methylene-BIS (2-chloroaniline), which is a suspect carcinogen and hence may be the subject of further restrictions of its use by the Occupational Safety and Health Administration (OSHA). The samples made in the configuration of cable joints and in the form of disks were evaluated for flammability and hypergolic compatibility. These also underwent accelerated weatherability tests that measured the residual hardness of the exposed samples. Three candidates and the existing compound passed the hardness test. Of these, only one candidate and the existing compound passed the flammability test. The thermal and hydrolytic stability (weatherability) of these samples was studied using thermogravimetric analysis (DSC) techniques. The TMA and DSC data correlated with the residual hardness data; whereas, the TGA data showed no correlation. A hypergolic compatibility test will be conducted on the compound V-356-HE80, which passed both the flammability and accelerated weatherability tests.

    One of the best methods for producing bulk homogeneous (composition) supported bimetallic AuPd clusters involves the immobilization of a protected Au seed followed by the addition of Pd. This paper investigates the importance of this gold seed in controlling the resulting bimetallic AuPd clusters structures, sizes and catalytic activities by investigating three different gold seeds. Uniform Au-Pd alloy were obtained when a steric/electrostatic protecting group, poly(vinyl alcohol) (PVA), was used to form the gold clusters on activated carbon (AC). In contrast Au/AC precursors prepared using Au nanoparticles with only electrostatic stabilization (tetrakis(hydroxypropyl)phosphonium chloride (THPC)), or no stabilization (magnetron sputtering) produced inhomogeneous alloys and segregation of the gold and palladium. The uniform alloyed catalyst (Pd{at}Au{sub PVA}/AC) is the most active and selective catalyst, while the inhomogenous catalysts are less active and selective. Further study of the PVA protected Au clusters revealed that the amount of PVA used is also critical for the preparation of uniform alloyed catalyst, their stability, and their catalytic activity.

    Three dimensional (3D) bioprinting technology enables the freeform fabrication of complex constructs from various hydrogels and is receiving increasing attention in tissue engineering. The objective of this study is to develop a novel self-supporting direct hydrogel printing approach to extrude complex 3D hydrogel composite structures in air without the help of a support bath. Laponite, a member of the smectite mineral family, is investigated to serve as an internal scaffold material for the direct printing of hydrogel composite structures in air. In the proposed printing approach, due to its yield-stress property, Laponite nanoclay can be easily extruded through a nozzle as a liquid and self-supported after extrusion as a solid. Its unique crystal structure with positive and negative charges enables it to be mixed with many chemically and physically cross-linked hydrogels, which makes it an ideal internal scaffold material for the fabrication of various hydrogel structures. By mixing Laponite nanoclay with various hydrogel precursors, the hydrogel composites retain their self-supporting capacity and can be printed into 3D structures directly in air and retain their shapes before cross-linking. Then, the whole structures are solidified in situ by applying suitable cross-linking stimuli. The addition of Laponite nanoclay can effectively improve the mechanical and biological properties of hydrogel composites. Specifically, the addition of Laponite nanoclay results in a significant increase in the Young's modulus of each hydrogel-Laponite composite: 1.9-fold increase for the poly(ethylene glycol) diacrylate (PEGDA)-Laponite composite, 7.4-fold increase for the alginate-Laponite composite, and 3.3-fold increase for the gelatin-Laponite composite.

    Given the costs of multiple mating, why has female polyandry evolved? Utetheisa ornatrix moths are well suited for studying multiple mating in females because females are highly polyandrous over their life span, with each male mate transferring a substantial spermatophore with both genetic and nongenetic material. The accumulation of resources might explain the prevalence of polyandry in this species, but another, not mutually exclusive, possibility is that females mate multiply to increase the probability that their sons will inherit more-competitive sperm. This latter "sexy-sperm" hypothesis posits that female multiple mating and male sperm competitiveness coevolve via a Fisherian runaway process. We tested the sexy-sperm hypothesis by using competitive double matings to compare the sperm competition success of sons of polyandrous versus monandrous females. In accordance with sexy-sperm theory, we found that in 511 offspring across 17 families, the male whose polyandrous mother mated once with each of three different males sired significantly more of all total offspring (81%) than did the male whose monandrous mother was mated thrice to a single male. Interestingly, sons of polyandrous mothers had a significantly biased sex ratio of their brood toward sons, also in support of the hypothesis. © 2015 The Author(s).

    The work of a hospital's medical staff is safety critical and often occurs under severe time constraints. To provide timely and effective cognitive support to medical teams working in such contexts, guidelines in the form of best practice workflows for healthcare have been developed by medical organizations. However, the high cognitive load imposed in such stressful and rapidly changing environments poses significant challenges to the medical staff or team in adhering to these workflows. In collaboration with physicians and nurses from Carle Foundation Hospital, we first studied and modeled medical team's individual responsibilities and interactions in cardiac arrest resuscitation and decomposed their overall task into a set of distinct cognitive tasks that must be specifically supported to achieve successful human-centered system design. We then developed a medical Best Practice Guidance (BPG) system for reducing medical teams' cognitive load, thus fostering real-time adherence to best practices. We evaluated the resulting system with physicians and nurses using a professional patient simulator used for medical training and certification. The evaluation results point to a reduction of cognitive load and enhanced adherence to medical best practices.

    The aim of this study was to find out if student nurses feel comfortable in caring by providing support for Lesbian, Gay, Bisexual or Questioning adolescents and what factors influence their level of comfort. Research indicates that nurses and nursing students experience varying levels of comfort when caring for adults who are Lesbian, Gay, Bisexual or Questioning: adult patients feel that nurse's attitudes change towards them once they disclose their sexuality. There has been minimal research to date on nursing attitudes to working with adolescents who are Lesbian, Gay, Bisexual or Questioning. Both quantitative and qualitative methods were used in this descriptive study. Questionnaires were completed by 152 nursing students and nine took part in semi-structured focus groups. A two-way ANOVA was used to analyse the questionnaires. Thematic analysis was used to identify the themes arising from the focus groups. Data were collected between August 2013 - July 2014. The results and findings of the study were that student nurse's felt discomfort in providing support; due to a lack of knowledge of Lesbian, Gay or Bisexual sexuality, personal and religious beliefs and the perceptions of others. However, all students indicated they had a positive attitude towards Lesbian, Gay, Bisexual and Questioning adolescents. More needs to be done to raise self-awareness and improve the level of knowledge in relation to Lesbian, Gay and Bisexual issues amongst student nurses. Educational institutions and practice areas need to recognize this fact and reflect this in their educational programmes. © 2016 John Wiley & Sons Ltd.

    Roscigno, Cecelia I.

    2016-01-01

    Objective A child’s severe traumatic brain injury (TBI) creates a family crisis requiring extensive cultural, informational, psychological, and environmental support. Nurses need to understand parents’ expectations of caring in early acute care so they can tailor their attitudes, beliefs, and behaviors appropriately to accommodate the family’s needs. Methods In a previous qualitative study of 42 parents or caregivers from 37 families of children with moderate to severe TBI, parents of children with severe TBI (n = 25) described their appraisals of nurse caring and uncaring behaviors in early acute care. Swanson’s theory of caring was used to categorize parents’ descriptions in order to inform nursing early acute care practices and family-centered care. Results Caring nurse encounters included: (a) involving parents in the care of their child and reflecting on all socio-cultural factors shaping family resources and responses (knowing); (b) respecting that family grief can be co-mingled with resilience, and that parents are typically competent to be involved in decision-making (maintaining belief); (d) actively listening and engaging parents in order to fully understand family values and needs (being with); (e) decreasing parents’ workload to get information, emotional support, and providing a safe cultural, psychological, and physical environment for the family (doing for), and; (f) providing anticipatory guidance to navigate the early acute care system and giving assistance to learn and adjust to their situation (enabling). Conclusion Application of Swanson’s caring theory is prescriptive in helping individual nurses and early acute care systems to meet important family needs following children’s severe TBI.

    Full Text Available Abstract Background Some people living with HIV/AIDS (PLHIV want to have children while others want to prevent pregnancies; this calls for comprehensive services to address both needs. This study explored decisions to have or not to have children and contraceptive preferences among PLHIV at two clinics in Uganda. Methods This was a qualitative cross-sectional study. We conducted seventeen focus group discussions and 14 in-depth interviews with sexually active adult men and women and adolescent girls and boys, and eight key informant interviews with providers. Overall, 106 individuals participated in the interviews; including 84 clients through focus group discussions. Qualitative latent content analysis technique was used, guided by key study questions and objectives. A coding system was developed before the transcripts were examined. Codes were grouped into categories and then themes and subthemes further identified. Results In terms of contraceptive preferences, clients had a wide range of preferences; whereas some did not like condoms, pills and injectables, others preferred these methods. Fears of complications were raised mainly about pills and injectables while cost of the methods was a major issue for the injectables, implants and intrauterine devices. Other than HIV sero-discordance and ill health (which was cited as transient, the decision to have children or not was largely influenced by socio-cultural factors. All adult men, women and adolescents noted the need to have children, preferably more than one. The major reasons for wanting more children for those who already had some were; the sex of the children (wanting to have both girls and boys and especially boys, desire for large families, pressure from family, and getting new partners. Providers were supportive of the decision to have children, especially for those who did not have any child at all, but some clients cited negative experiences with providers and information gaps for

    Purpose: Evaluate the influence of abutment's material and geometry on stress distribution in a single implant-supported prosthesis. Materials and Methods: Three-dimensional models were made based on tomographic slices of the upper middle incisor area, in which a morse taper implant was positioned and a titanium (Ti) or zirconia (ZrN) universal abutments was installed. The commercially available geometry of titanium (T) and zirconia (Z) abutments were used to draw two models, TM1 and ZM1 respectively, which served as control groups. These models were compared with 2 experimental groups were the mechanical properties of Z were applied to the titanium abutment (TM2) and vice versa for the zirconia abutment (ZM2). Subsequently, loading was simulated in two steps, starting with a preload phase, calculated with the respective friction coefficients of each materials, followed by a combined preload and chewing force. The maximum von Mises stress was described. Data were analyzed by two-way ANOVA that considered material composition, geometry and loading (p < 0.05). Results: Titanium and zirconia abutments showed similar von Mises stresses in the mechanical part of the four models. The area with the highest concentration of stress was the screw thread, following by the screw body. The highest stress levels occurred in screw thread was observed during the preloading phase in the ZM1 model (931 MPa); and during the combined loading in the TM1 model (965 MPa). Statistically significant differences were observed for loading, the material × loading interaction, and the loading × geometry interaction (p < 0.05). Preloading contributed for 77.89% of the stress (p < 0.05). There were no statistically significant differences to the other factors (p > 0.05). Conclusion: The screw was the piece most intensely affected, mainly through the preload force, independent of the abutment's material. - Highlights: • The abutment's screw was the most impaired piece of the

    Unsuccessfully sealed screw access channels of prosthetic implant abutments may lead to malodor or peri-implant diseases in gingival tissues adjacent to implant-supported restorations. Therefore, 72 sets of screw channel analogs with six different materials incorporated (Polytetrafluoroethylene (PTFE), wax, gutta-percha, cavit, endofrost-pellets and cotton pellets) were exposed (2.5 h, 37°C) to Streptococcus mutans, oralis and Candida albicans suspensions. Bacterial adherence was quantified by using the fluorescence dye, Alamar Blue/resazurin, and an automated multifunctional reader. For quantification of fungal adherence the ATP-based bioluminescence approach was used. High relative fluorescence and luminescence intensities (>10,000), indicating high adhesion of streptococci and fungi were found for cotton and endofrost-pellets and low intensities (cavit and PTFE. The quantity of bacterial and fungal adhesion differed significantly between the assessed various sealing materials. In conclusion and within the limitations of this study, wax, gutta-percha, cavit and PTFE should be preferred as sealing materials.

    Solar light-active Zr-doped TiO2 nanoparticles were successfully immobilized on delaminated clay materials by a one-step sol-gel route. Fixing the amount of TiO2 at 65wt.%, this work studies the influence of Zr loading (up to 2%) on the photocatalytic activity of the resulting Zr-doped TiO2/clay materials. The structural characterization demonstrates that all samples were formed by a delaminated clay with nanostructured anatase assembled on its surface. The Zr dopant was successfully incorporated into the anatase lattice, resulting in a slight deformation of the anatase crystal and the reduction of the band gap. These materials exhibit high surface area with a disordered mesoporous structure formed by TiO2 particles (15-20nm) supported on a delaminated clay. They were tested in the solar photodegradation of antipyrine, usually used as an analgesic drug and selected as an example of emerging pollutant. High degradation rates have been obtained at low antipyrine concentrations and high solar irradiation intensities with the Zr-doped TiO2/clay catalyst, more effective than the undoped one. This work demonstrates the potential application of the synthesis method for preparing novel and efficient solar-light photocatalysts based on metal-doped anatase and a delaminated clay.

    Full Text Available Au-based catalysts supported on carbon materials with different structures such as graphite (G and fishbone type carbon nanofibers (CNF-F were prepared using two different methods (impregnation and gold-sol to be tested in the water gas shift (WGS reaction. Atomic absorption spectrometry, transmission electron microscopy (TEM, temperature-programmed oxidation (TPO, X-ray diffraction (XRD, Raman spectroscopy, elemental analyses (CNH, N2 adsorption-desorption analysis, temperature-programmed reduction (TPR and temperature-programmed decomposition were employed to characterize both the supports and catalysts. Both the crystalline nature of the carbon supports and the method of gold incorporation had a strong influence on the way in which Au particles were deposited on the carbon surface. The higher crystallinity and the smaller and well dispersed Au particle size were, the higher activity of the catalysts in the WGS reaction was noted. Finally, catalytic activity showed an important dependence on the reaction temperature and steam-to-CO molar ratio.

    Stroke is one of the major causes of death and disability in America. After stroke, about 65% of survivors still suffer from severe paresis, while rehabilitation treatment strategy after stroke plays an essential role in recovery. Currently, there is a clinical trial (NIH award #HD065438) to determine the optimal dose of rehabilitation for persistent recovery of arm and hand paresis. For DOSE (Dose Optimization Stroke Evaluation), laboratory-based measurements, such as the Wolf Motor Function test, behavioral questionnaires (e.g. Motor Activity Log-MAL), and MR, DTI, and Transcranial Magnetic Stimulation (TMS) imaging studies are planned. Current data collection processes are tedious and reside in various standalone systems including hardcopy forms. In order to improve the efficiency of this clinical trial and facilitate decision support, a web-based imaging informatics system has been implemented together with utilizing mobile devices (eg, iPAD, tablet PC's, laptops) for collecting input data and integrating all multi-media data into a single system. The system aims to provide clinical imaging informatics management and a platform to develop tools to predict the treatment effect based on the imaging studies and the treatment dosage with mathematical models. Since there is a large amount of information to be recorded within the DOSE project, the system provides clinical data entry through mobile device applications thus allowing users to collect data at the point of patient interaction without typing into a desktop computer, which is inconvenient. Imaging analysis tools will also be developed for structural MRI, DTI, and TMS imaging studies that will be integrated within the system and correlated with the clinical and behavioral data. This system provides a research platform for future development of mathematical models to evaluate the differences between prediction and reality and thus improve and refine the models rapidly and efficiently.
