A rhodium-catalyzed chemo-, regio-, and enantioselective addition of 2-pyridones to terminal allenes to give branched N-allyl 2-pyridones is reported. Preliminary mechanistic studies support the hypothesis that the reaction was initiated from the more acidic 2-hydroxypyridine form, and the initial kinetic O-allylation product was finally converted into the thermodynamically more stable N-allyl 2-pyridones. © 2014 WILEY-VCH Verlag GmbH & Co.

Reduction of N2 by supported tungsten clusters gives a model of the process by nitrogenase

PubMed Central

Murakami, Junichi; Yamaguchi, Wataru

2012-01-01

Metalloenzymes catalyze difficult chemical reactions under mild conditions. Mimicking their functions is a challenging task and it has been investigated using homogeneous systems containing metal complexes. The nitrogenase that converts N2 to NH3 under mild conditions is one of such enzymes. Efforts to realize the biological function have continued for more than four decades, which has resulted in several reports of reduction of N2, ligated to metal complexes in solutions, to NH3 by protonation under mild conditions. Here, we show that seemingly distinct supported small tungsten clusters in a dry environment reduce N2 under mild conditions like the nitrogenase. N2 is reduced to NH3 via N2H4 by addition of neutral H atoms, which agrees with the mechanism recently proposed for the N2 reduction on the active site of nitrogenase. The process on the supported clusters gives a model of the biological N2 reduction. PMID:22586517

Social support and ambulatory blood pressure: an examination of both receiving and giving.

PubMed

Piferi, Rachel L; Lawler, Kathleen A

2006-11-01

The relationship between the social network and physical health has been studied extensively and it has consistently been shown that individuals live longer, have fewer physical symptoms of illness, and have lower blood pressure when they are a member of a social network than when they are isolated. Much of the research has focused on the benefits of receiving social support from the network and the effects of giving to others within the network have been neglected. The goal of the present research was to systematically investigate the relationship between giving and ambulatory blood pressure. Systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate were recorded every 30 min during the day and every 60 min at night during a 24-h period. Linear mixed models analyses revealed that lower systolic and diastolic blood pressure and mean arterial pressure were related to giving social support. Furthermore, correlational analyses revealed that participants with a higher tendency to give social support reported greater received social support, greater self-efficacy, greater self-esteem, less depression, and less stress than participants with a lower tendency to give social support to others. Structural equation modeling was also used to test a proposed model that giving and receiving social support represent separate pathways predicting blood pressure and health. From this study, it appears that giving social support may represent a unique construct from receiving social support and may exert a unique effect on health.

Life Problems and Perceptions of Giving Support: Implications for Aging Mothers and Middle-Aged Children

2017-01-01

Giving support may be a stressful or rewarding experience, little is known about how family members perceive giving support amidst problems or crises. Using a sample of 226 mother-child dyads (mother mean age = 75.04; child mean age = 49.57), we examine how mothers and their middle-aged children perceive giving support in the context of life problems. Actor–partner interdependence models tested whether associations between problems and perceptions of support are moderated by frequency of support given and if associations were stronger for daughters or sons. Children perceived giving support to their mother as more stressful when they had more of their own problems and gave high levels of support. Daughters, but not sons, considered helping their mother more stressful when their mother had more problems and they gave high levels of support. Distinctions between mother-son and mother-daughter dyads demonstrate the merit of a dyadic approach to understanding mother-child relationships. PMID:29720778

Reduced reciprocal giving in social anxiety - Evidence from the Trust Game.

PubMed

Anderl, Christine; Steil, Regina; Hahn, Tim; Hitzeroth, Patricia; Reif, Andreas; Windmann, Sabine

2018-06-01

Social anxiety is known to impair interpersonal relationships. These impairments are thought to partly arise from difficulties to engage in affiliative interactions with others, such as sharing favors or reciprocating prosocial acts. Here, we examined whether individuals high compared to low in social anxiety differ in giving towards strangers in an economic game paradigm. One hundred and twenty seven non-clinical participants who had been pre-screened to be either particularly high or low in social anxiety played an incentivized Trust Game to assess trustful and reciprocal giving towards strangers in addition to providing information on real life interpersonal functioning (perceived social support and attachment style). We found that reciprocal, but not trustful giving, was significantly decreased among highly socially anxious individuals. Both social anxiety and reciprocal giving furthermore showed significant associations with self-reported real life interpersonal functioning. Participants played the Trust Game with the strategy method; results need replication with a clinical sample. Individuals high in social anxiety showed reduced reciprocal, but intact trustful giving, pointing to a constraint in responsiveness. The research may contribute to the development of new treatment and prevention programs to reduce the interpersonal impairments in socially anxious individuals. Copyright © 2017 Elsevier Ltd.

Chen, Jacqueline M; Kim, Heejung S; Mojaverian, Taraneh; Morling, Beth

2012-01-01

The present research examined cultural differences in the type and frequency of support provided as well as the motivations underlying these behaviors. Study 1, an open-ended survey, asked participants about their social interactions in the past 24 hours and found that European Americans reported providing emotion-focused support more frequently than problem-focused support, whereas Japanese exhibited the opposite pattern. Study 2, a closed-ended questionnaire study, found that, in response to the close other's big stressor, European Americans provided more emotion-focused support whereas Japanese provided equivalent amounts of emotion-focused and problem-focused support. In addition, Study 2 examined motivational explanations for these differences. Social support provision was motivated by the goal of closeness and increasing recipient self-esteem among European Americans, but only associated with the motive for closeness among Japanese. These studies illustrate the importance of considering cultural context and its role in determining the meaning and function of various support behaviors.

Dramatic Influence of an Anionic Donor on the Oxygen-Atom Transfer Reactivity of a MnV–Oxo Complex

Addition of an anionic donor to an MnV(O) porphyrinoid complex causes a dramatic increase in 2-electron oxygen-atom-transfer (OAT) chemistry. The 6-coordinate [MnV(O)(TBP8Cz)(CN)]− was generated from addition of Bu4N+CN− to the 5-coordinate MnV(O) precursor. The cyanide-ligated complex was characterized for the first time by Mn K-edge X-ray absorption spectroscopy (XAS) and gives Mn–O=1.53 Å, Mn–CN=2.21 Å. In combination with computational studies these distances were shown to correlate with a singlet ground state. Reaction of the CN− complex with thioethers results in OAT to give the corresponding sulfoxide and a 2e−-reduced MnIII(CN)− complex. Kinetic measurements reveal a dramatic rate enhancement for OAT of approximately 24 000-fold versus the same reaction for the parent 5-coordinate complex. An Eyring analysis gives ΔH≠=14 kcal mol−1, ΔS≠=−10 cal mol−1 K−1. Computational studies fully support the structures, spin states, and relative reactivity of the 5- and 6-coordinate MnV(O) complexes. PMID:25256417

The Internet can increase access to psychosocial care for breast cancer survivors through online support groups. This study will test a novel prosocial online group that emphasizes both opportunities for getting and giving help. Based on the helper therapy principle, it is hypothesized that the addition of structured helping opportunities and coaching on how to help others online will increase the psychological benefits of a standard online group. A two-armed randomized controlled trial with pretest and posttest. Non-metastatic breast cancer survivors with elevated psychological distress will be randomized to either a standard facilitated online group or to a prosocial facilitated online group, which combines online exchanges of support with structured helping opportunities (blogging, breast cancer outreach) and coaching on how best to give support to others. Validated and reliable measures will be administered to women approximately one month before and after the interventions. Self-esteem, positive affect, and sense of belonging will be tested as potential mediators of the primary outcomes of depressive/anxious symptoms and sense of purpose in life. This study will test an innovative approach to maximizing the psychological benefits of cancer online support groups. The theory-based prosocial online support group intervention model is sustainable, because it can be implemented by private non-profit or other organizations, such as cancer centers, which mostly offer face-to-face support groups with limited patient reach.

A protocol by which ketone or ester enolates and ortho-quinone methides (o-QMs) are generated in situ in a single reaction flask from silylated precursors under the action of anhydrous fluoride is reported. The reaction partners are joined to give a variety of β-(2-hydroxyphenyl)-carbonyl compounds in 32–94% yield in a single laboratory operation. The intermediacy of o-QMs is supported by control experiments utilizing enolate precursors and conventional alkyl halides as competitive alkylating agents and the isolation of 1,5-dicarbonyl products resulting from conjugate additions that do not restore the aromatic system.

Richter, Thomas; Bruylants, Tim; Schelkens, Peter; Ebrahimi, Touradj

2015-09-01

The JPEG standard has known an enormous market adoption. Daily, billions of pictures are created, stored and exchanged in this format. The JPEG committee acknowledges this success and spends continued efforts in maintaining and expanding the standard specifications. JPEG XT is a standardization effort targeting the extension of the JPEG features by enabling support for high dynamic range imaging, lossless and near-lossless coding, and alpha channel coding, while also guaranteeing backward and forward compatibility with the JPEG legacy format. This paper gives an overview of the current status of the JPEG XT standards suite. It discusses the JPEG legacy specification, and details how higher dynamic range support is facilitated both for integer and floating-point color representations. The paper shows how JPEG XT's support for lossless and near-lossless coding of low and high dynamic range images is achieved in combination with backward compatibility to JPEG legacy. In addition, the extensible boxed-based JPEG XT file format on which all following and future extensions of JPEG will be based is introduced. This paper also details how the lossy and lossless representations of alpha channels are supported to allow coding transparency information and arbitrarily shaped images. Finally, we conclude by giving prospects on upcoming JPEG standardization initiative JPEG Privacy & Security, and a number of other possible extensions in JPEG XT.

2002-01-01

BACKGROUND There are few data available on how physicians inform patients about bad news. We surveyed internists about how they convey this information. METHODS We surveyed internists about their activities in giving bad news to patients. One set of questions was about activities for the emotional support of the patient (11 items), and the other was about activities for creating a supportive environment for delivering bad news (9 items). The impact of demographic factors on the performance of emotionally supportive items, environmentally supportive items, and on the number of minutes reportedly spent delivering news was analyzed by analysis of variance and multiple regression analysis. RESULTS More than half of the internists reported that they always or frequently performed 10 of the 11 emotionally supportive items and 6 of the 9 environmentally supportive items while giving bad news to patients. The average time reportedly spent in giving bad news was 27 minutes. Although training in giving bad news had a significant impact on the number of emotionally supportive items reported (P < .05), only 25% of respondents had any previous training in this area. Being older, a woman, unmarried, and having a history of major illness were also associated with reporting a greater number of emotionally supportive activities. CONCLUSIONS Internists report that they inform patients of bad news appropriately. Some deficiencies exist, specifically in discussing prognosis and referral of patients to support groups. Physician educational efforts should include discussion of prognosis with patients as well as the availability of support groups. PMID:12472927

2017-09-01

To evaluate the feasibility of an oncological occupational physician (OOP) who is trained in oncological work-related problems, and in providing work-related support to cancer patients within the curative setting. We assessed facilitators and barriers that affect the activities of an OOP, and the satisfaction of the OOPs and patients with this new form of health care. Interviews were held with (1) OOPs (N = 13) to assess facilitators, barriers and their satisfaction with their ability to give supportive care and (2) cancer patients (N = 8) to assess their satisfaction concerning consulting an OOP. The main facilitators were positive feedback from health care providers and patients about the received care and support that the OOP had given, and the additional knowledge of the OOPs about cancer and work-related problems. Major barriers for being active as an OOP were lack of financial support for the OOP and the unfamiliarity of patients and health care providers with the specialised occupational physician. Both OOPs and the specialised knowledge and additional training of the OOPs facilitated providing support to cancer patients and survivors with work-related problems. Familiarity with the specialised occupational physician and financial support should be improved. © 2015 John Wiley & Sons Ltd.

Care for a break? An investigation of informal caregivers' attitudes toward respite care using Q-methodology.

To investigate informal caregivers' attitudes toward respite care. Interviews with informal caregivers during open-house support groups (three) for informal caregivers, conducted late 2004 at Informal Care Support Centres in the city of Rotterdam, The Netherlands. A Q-methodological study was conducted. Informal caregivers were asked to rank-order 39 statements regarding motivation for providing informal care; supporting capacity; physical, psychological, practical, financial, relational and social obstacles; subjective burden; need for support; experienced support; and propensity and impediments to make use of respite care. In addition, respondents explained their Q-sort in writing and completed a questionnaire regarding characteristics of the caregiver, the care recipient, and the objective and subjective burden of their care giving situation. Individual Q-sorts were analysed using PQMethod 2.11 (statistical method factor analysis with a varimax rotation). Objective of Q-analysis was to reveal a limited number of corresponding ways the statements were sorted. For the factors identified, composite sorts were determined. Factors were interpreted and described using the composite sorts, differences and similarities in rank value of statements between factors and the explanations by respondents. We found three distinct groups of caregivers: informal caregivers who need and ask for respite care, those who need but won't ask for respite care, and those that do not need respite care. Caregivers in the first two groups experience substantial burden, while those in the third group enjoy sufficient support and appear to manage pretty well. Caregivers in the second and third group derive considerable satisfaction from care giving. On balance, caregivers in the first two groups would sometimes rather have someone else take over their task. The first group feels misunderstood and undervalued by health and welfare organisations and has problems obtaining respite. The desire for respite of caregivers in the second group is not unambiguous, affected by care recipient resistance against respite. Respite care programmes should target caregivers in the first two groups. Regarding the second group, effort should be directed to both caregiver and care recipient. They need to be convinced that it is in their mutual interest to make the care giving task manageable in the long run, because they report serious burden from care giving coupled with a resistance to respite care.

According to a new hypothesis based on implicit egotism, people gravitate toward cities, states, and careers with names similar to their own names. To support this hypothesis, B. W. Pelham, M. C. Mirenberg, and J. T. Jones (2002) reported a series of results regarding distributions of names in different cities, states, and jobs. In the present article, new analyses of the original data are reported, showing that the hypothesis is not supported for the large majority of names considered by the authors, and for some names even the opposite result is found. In addition, a meta-analysis reveals that either the data are unreliable, or the hypothesis cannot be supported in the whole population of names. Overall, the original data give no support of the idea that implicit egotism influences major life decisions.

The small-angle scattering from fractally rough surfaces has the potential to give information on the surface area at a given resolution. By use of quantitative neutron and x-ray scattering, a direct comparison of surface areas of fractally rough powders was made between scattering and adsorption techniques. This study supports a recently proposed correction to the theory for scattering from fractal surfaces. In addition, the scattering data provide an independent calibration of molecular adsorbate areas.

A new approach is presented to form self-supported bimetallic nanosized solids with acid and redox catalytic properties. They are water-, air- and H2-stable, and are able to activate demanding C–C and C–H reactions. A detailed mechanistic study on the formation of the Ag–Fe bimetallic system shows that a rapid redox-coupled sequence between Ag+, O2 (air) and Fe2+ occurs, giving monodisperse Ag nanoparticles supported by O-bridged diatomic Fe3+ triflimides. The system can be expanded to Ag nanoparticles embedded within a matrix of Cu2+, Bi3+ and Yb3+ triflimide. PMID:28451218

Pharmacokinetics of topically applied pilocarpine in the albino rabbit eye.

PubMed

Makoid, M C; Robinson, J R

1979-04-01

The temporal and spatial pattern of [3H]-pilocarpine nitrate distribution in the albino rabbit eye following topical administration was determined. A four-compartment caternary chain model describing this disposition corresponds to the precorneal area, the cornea, the aqueous humor, and the lens and vitreous. Simultaneous computer fitting of data from tissue corresponding to some compartments in the model supported the proposed model. Additional support was provided by the excellent correlation between predicted and observed values in multiple-dosing studies. Several important aspects of ocular drug disposition are evident from the model. The extensive parallel elimination at the absorption site gives rise to an apparent absorption rate constant that is one to two orders of magnitude larger than the true absorption rate constant. In addition, aqueous flow accounts for most of the drug removal. Thus, major effects on absorption and elimination, independent of the drug structure, suggest the possibility of similar pharmacokinetics for vastly different drugs.

This article describes the development and implementation of a policy to support community professionals to train informal carers to give, 'as required ', subcutaneous medications to their relative. In a rural county, Lincolnshire, despite out of hours responsive services, patients could wait up to one hour for subcutaneous medications. Additionally there were increasing requests from carers to participate in this role. To provide a safe and effective framework via a robust policy to support informal carers to give, as required, subcutaneous medications in today's health-care environment. A group of professionals working in adult community palliative care formed a working party to scope the literature and existing policies, and to consider risks, legalities and local infrastructure. The policy was developed and based on available literature. A consultation process on the policy was commenced before a series of educational workshops supported its roll out. The small number of informal carers (n=5) who undertook this role reported positive experiences and felt empowered. Professionals found the policy was able to be implemented quickly and was adhered to. From the small numbers audited it could be suggested that if the process is well managed and the informal carers feel supported they can safely and effectively administer subcutaneous injections in community palliative care. More importantly, if a policy is available, staff can respond to requests from carers in a timely manner.

Currently, no consensus exists for the appropriate treatment of echocardiographically diagnosed mobile right heart masses giving rise to a high suspicion of migrant thromboembolism in patients with pulmonary embolism. This may lead to unnecessary delay in the implementation of the most appropriate treatment for these patients. Several earlier studies have supported the beneficial role of thrombolytic therapy. We report on an additional two patients with mobile right heart thromboemboli, refractory to systemic anticoagulation, who recovered quickly after initiation of thrombolytic therapy.

Social support is an important element of family medicine within a primary care setting, delivered by general practitioners and practice nurses in addition to usual clinical care. The aim of the study was to explore general practitioner's, practice nurse's and people with type 2 diabetes' views, experiences and perspectives of the importance of social support in caring for people with type 2 diabetes and their role in providing social support. Interviews with general practitioners (n=10) and focus groups with practice nurses (n=10) and people with diabetes (n=9). All data were audio-recorded, fully transcribed and thematically analysed using qualitative content analysis by Mayring. All participants emphasized the importance of the concept of social support and its impacts on well-being of people with type 2 diabetes. Social support is perceived helpful for people with diabetes in order to improve diabetes control and give support for changes in lifestyle habits (physical activity and dietary changes). General practitioners identified a lack of information about facilities in the community like sports or self-help groups. Practice nurses emphasized that they need more training, such as in dietary counselling. Social support given by general practitioners and practice nurses plays a crucial role for people with type 2 diabetes and is an additional component of social care. However there is a need for an increased awareness by general practitioners and practice nurses about the influence social support could have on the individual's diabetes management.

Visualization method to give precise location/posture of surgical instruments is indispensable for accurate control and faultless operation. In this paper, the authors propose three-side-view presentation method for precise location/posture control of surgical instruments in telesurgery. The experimental results show that the proposed method improved accurate positioning of a telemanipulator.

An Empirical Review of the Neural Underpinnings of Receiving and Giving Social Support: Implications for Health

PubMed Central

Eisenberger, Naomi I.

2013-01-01

Decades of research have demonstrated strong links between social ties and health. Although considerable evidence has shown that social support can attenuate downstream physiological stress responses that are relevant to health, the neurocognitive mechanisms that translate perceptions of social ties into altered physiological responses are still not fully understood. This review integrates research from social and affective neuroscience to illuminate some of the neural mechanisms involved in social support processes, which may further our understanding of the ways in which social support influence health. This review focuses on two types of social support that have been shown to relate to health: receiving and giving social support. As the neural basis of receiving support, this article reviews the hypothesis that receiving support may benefit health through the activation of neural regions that respond to safety and inhibit threat-related neural and physiological responding. This article will then review neuroimaging studies in which subjects were primed with or received support during a negative experience as well as studies in which self-reports of perceived support were correlated with neural responses to a negative experience. As the neural basis of giving support, this article reviews the hypothesis that neural regions involved in maternal caregiving behavior may be critical for the health benefits of support-giving through the inhibition of threat-related neural and physiological responding. Neuroimaging studies in which subjects provided support to others or engaged in other related forms of prosocial behavior will then be reviewed. Implications of these findings for furthering our understanding of the relationships between social support and health are discussed. PMID:23804014

Few data are available on the specific care giving-related problems of stroke patient's caregivers and factors that influence the burden of these caregivers. To study the influences of the active rehabilitation process on anxiety, depression, care burden and perceived social support level of stroke patients caregivers. A prospective clinical trial. Patients and caregivers entering a rehabilitation program at a university hospital in Turkey. Ninety patients with a first episode of stroke and 90 caregivers responsible for their care were recruited for our study. Patients and caregivers were assessed before and after the active rehabilitation process. The functional disability level of the patients was assessed by Functional Independence Measure (FIM). The Beck Anxiety Scale (BAS) and the Beck Depression Scale (BDS) were used for anxiety and depression assessment, the Zarit Care Burden Scale (ZCBS) for care burden assessment and the Multi-Dimensional Scale of Perceived Social Support (MDSPSS) for perceived social support assessment. A statistically significant rise is observed in the special person sub-assessment of MDSPSS in both female and male caregivers. Also, a significant decrease in care burden, anxiety and depression levels of caregivers was noted after the rehabilitation program (p < 0.05). Caregivers accept the rehabilitation period as important social support in addition to the support provided by family and friends. Also, our positive results were associated with an improvement in the patients' functional level and an increase in the acquisition of knowledge and skill required of caregivers in order to provide care during rehabilitation. The rehabilitation team should be aware of the fact that the perceived care burden may be greater due to the lack of knowledge concerning available resources and due to the inability to cope with stress effectively.

The role of support staff in promoting the social inclusion of persons with an intellectual disability.

Past studies have found that people supported in more individualised housing options tend to have levels of community participation and wider social networks than those in other accommodation options. Yet, the contribution of support staff in facilitating social inclusion has received relatively scant attention. In all 245 staff working in either supported living schemes, or shared residential and group homes, or in day centres completed a written questionnaire in which they rated in terms of priority to their job, 16 tasks that were supportive of social inclusion and a further 16 tasks that related to the care of the person they supported. In addition staff identified those tasks that they considered were not appropriate to their job. Across all three service settings, staff rated more care tasks as having higher priority than they did the social inclusion tasks. However, staff in supported living schemes rated more social inclusion tasks as having high priority than did staff in the other two service settings. Equally the staff who were most inclined to rate social inclusion tasks as not being applicable to their job were those working day centres; female rather than male staff, those in front-line staff rather than senior staff, and those in part-time or relief positions rather than full-time posts. However, within each service settings, there were wide variations in how staff rated the social inclusion tasks. Staff working in more individualised support arrangements tend to give greater priority to promoting social inclusion although this can vary widely both across and within staff teams. Nonetheless, staff gave greater priority to care tasks especially in congregated service settings. Service managers may need to give more emphasis to social inclusion tasks and provide the leadership, training and resources to facilitate support staff to re-assess their priorities.

Plasmon transmutation: inducing new modes in nanoclusters by adding dielectric nanoparticles.

Planar clusters of coupled plasmonic nanoparticles support nanoscale electromagnetic "hot spots" and coherent effects, such as Fano resonances, with unique near and far field signatures, currently of prime interest for sensing applications. Here we show that plasmonic cluster properties can be substantially modified by the addition of individual, discrete dielectric nanoparticles at specific locations on the cluster, introducing new plasmon modes, or transmuting existing plasmon modes to new ones, in the resulting metallodielectric nanocomplex. Depositing a single carbon nanoparticle in the junction between a pair of adjacent nanodisks induces a metal-dielectric-metal quadrupolar plasmon mode. In a ten-membered cluster, placement of several carbon nanoparticles in junctions between multiple adjacent nanoparticles introduces a collective magnetic plasmon mode into the Fano dip, giving rise to an additional subradiant mode in the metallodielectric nanocluster response. These examples illustrate that adding dielectric nanoparticles to metallic nanoclusters expands the number and types of plasmon modes supported by these new mixed-media nanoscale assemblies.

Long-term Mechanical Circulatory Support System reliability recommendation by the National Clinical Trial Initiative subcommittee.

Lee, James

2009-01-01

The Long-Term Mechanical Circulatory Support (MCS) System Reliability Recommendation was published in the American Society for Artificial Internal Organs (ASAIO) Journal and the Annals of Thoracic Surgery in 1998. At that time, it was stated that the document would be periodically reviewed to assess its timeliness and appropriateness within 5 years. Given the wealth of clinical experience in MCS systems, a new recommendation has been drafted by consensus of a group of representatives from the medical community, academia, industry, and government. The new recommendation describes a reliability test methodology and provides detailed reliability recommendations. In addition, the new recommendation provides additional information and clinical data in appendices that are intended to assist the reliability test engineer in the development of a reliability test that is expected to give improved predictions of clinical reliability compared with past test methods. The appendices are available for download at the ASAIO journal web site at www.asaiojournal.com.

An Additive Definition of Molecular Complexity.

PubMed

Böttcher, Thomas

2016-03-28

A framework for molecular complexity is established that is based on information theory and consistent with chemical knowledge. The resulting complexity index Cm is derived from abstracting the information content of a molecule by the degrees of freedom in the microenvironments on a per-atom basis, allowing the molecular complexity to be calculated in a simple and additive way. This index allows the complexity of any molecule to be universally assessed and is sensitive to stereochemistry, heteroatoms, and symmetry. The performance of this complexity index is evaluated and compared against the current state of the art. Its additive character gives consistent values also for very large molecules and supports direct comparisons of chemical reactions. Finally, this approach may provide a useful tool for medicinal chemistry in drug design and lead selection, as demonstrated by correlating molecular complexities of antibiotics with compound-specific parameters.

In this chapter, we give an overview of the main Data Mining techniques used in the context of Recommender Systems. We first describe common preprocessing methods such as sampling or dimensionality reduction. Next, we review the most important classification techniques, including Bayesian Networks and Support Vector Machines. We describe the k-means clustering algorithm and discuss several alternatives. We also present association rules and related algorithms for an efficient training process. In addition to introducing these techniques, we survey their uses in Recommender Systems and present cases where they have been successfully applied.

Clay is a type of soil with particles of certain minerals giving plastic properties when mixed with water. Soil has an important role in a construction, besides as a building material in a wide variety of civil engineering works, soil is also used as supporting foundation of the building. Basic properties of clay are rock-solid in dry and plastic with medium water content. In high water content, clay becomes sticky like (cohesive) and soften. Therefore, clay stabilization is necessary to repair soil’s mechanical properties. In this research, lime is use as a stabilizer that contains the Ca+ element to bond bigger particles. Lime used is slaked lime Ca(OH)2. Clay used has liquid limitation (LL) value of 47.33%, plasticity index of 29.88% and CBR value 6.29. The results explain about 10% lime mixture variation gives the optimum stabilized clay with CBR value of 8.75%.

Addition of an anionic donor to an Mn(V) (O) porphyrinoid complex causes a dramatic increase in 2-electron oxygen-atom-transfer (OAT) chemistry. The 6-coordinate [Mn(V) (O)(TBP8 Cz)(CN)](-) was generated from addition of Bu4 N(+) CN(-) to the 5-coordinate Mn(V) (O) precursor. The cyanide-ligated complex was characterized for the first time by Mn K-edge X-ray absorption spectroscopy (XAS) and gives MnO=1.53 Å, MnCN=2.21 Å. In combination with computational studies these distances were shown to correlate with a singlet ground state. Reaction of the CN(-) complex with thioethers results in OAT to give the corresponding sulfoxide and a 2e(-) -reduced Mn(III) (CN)(-) complex. Kinetic measurements reveal a dramatic rate enhancement for OAT of approximately 24 000-fold versus the same reaction for the parent 5-coordinate complex. An Eyring analysis gives ΔH(≠) =14 kcal mol(-1) , ΔS(≠) =-10 cal mol(-1)  K(-1) . Computational studies fully support the structures, spin states, and relative reactivity of the 5- and 6-coordinate Mn(V) (O) complexes. © 2014 The Authors. Published by Wiley-VCHVerlag GmbH & Co.

1995-05-01

The DLR Microgravity User Support Centre (MUSC) in Cologne has supported microgravity experiments in the field of materials and life sciences since 1979. In the beginning of user support activities, MUSC tasks comprised the basic ground and mission support, whereas present programmes are expanded on, for example, powerful telescience and advanced real time data acquisition capabilities for efficient experiment operation and monitoring. In view of the Space Station era, user support functions will increase further. Additional tasks and growing responsibilities must be covered, e.g. extended science support as well as experiment and facility operations. The user support for TEMPUS IML-2, under contract of the German Space Agency DARA, represents a further step towards the required new-generation of future ground programme. TEMPUS is a new highly sophisticated Spacelab multi-user facility for containerless processing of metallic samples. Electromagnetic levitation technique is applied and various experiment diagnosis tools are offered. Experiments from eight U.S. and German investigator groups have been selected for flight on the second International Microgravity Laboratory Mission IML-2 in 1994. Based on the experience gained in the research programme of the DLR Institute for Space Simulation since 1984, MUSC is performing a comprehensive experiment preparation programme in close collaboration with the investigator teams. Complex laboratory equipment has been built up for technology and experiment preparation development. New experiment techniques have been developed for experiment verification tests. The MUSC programme includes thorough analysis and testing of scientific requirements of every proposed experiment with respect to the facility hard- and software capabilities. In addition, studies on the experiment-specific operation requirements have been performed and suitable telescience scenarios were analysed. The present paper will give a survey of the TEMPUS user support tasks emphasizing the advanced science support activities, which are considered significant for future ground programmes.

Although peer support in response to online disclosures of suicidality may be imperative for suicide prevention efforts, little is known as to how often support is provided or what predicts giving support. This study addresses this issue by investigating the odds of providing peer support in response to simulated online disclosures of suicidality. While interacting with a simulated Facebook newsfeed, participants (N = 690, M age  = 20.24, 527 female) were given the opportunity to leave comments on two posts disclosing low, moderate, or severe risk for suicide. Participants also completed questionnaires on their symptoms of depression and anxiety, experience with a loved one's suicidality, and Facebook use strategies. Only 33.6% of participants left a positive, supportive comment on at least one of the two suicide posts. Content severity, experience with a loved one's suicide attempts, and use of Facebook to meet people were predictive of providing positive comments. These findings suggest that young adults vary in their propensity to provide support after encountering a suicide disclosure online and that giving support is driven by a combination of contextual and intrapersonal factors. © 2018 The American Association of Suicidology.

Tooth renewal is initiated from epithelium associated with existing teeth. The development of new teeth requires dental epithelial cells that have competence for tooth formation, but specific marker genes for these cells have not been identified. Here, we analyzed expression patterns of the transcription factor Sox2 in two different modes of successional tooth formation: tooth replacement and serial addition of primary teeth. We observed specific Sox2 expression in the dental lamina that gives rise to successional teeth in mammals with one round of tooth replacement as well as in reptiles with continuous tooth replacement. Sox2 was also expressed in the dental lamina during serial addition of mammalian molars, and genetic lineage tracing indicated that Sox2+ cells of the first molar give rise to the epithelial cell lineages of the second and third molars. Moreover, conditional deletion of Sox2 resulted in hyperplastic epithelium in the forming posterior molars. Our results indicate that the Sox2+ dental epithelium has competence for successional tooth formation and that Sox2 regulates the progenitor state of dental epithelial cells. The findings imply that the function of Sox2 has been conserved during evolution and that tooth replacement and serial addition of primary teeth represent variations of the same developmental process. The expression patterns of Sox2 support the hypothesis that dormant capacity for continuous tooth renewal exists in mammals. PMID:23462476

The reaction of triazolinediones (TADs) and indoles is of particular interest for polymer chemistry applications, as it is a very fast and irreversible additive-free process at room temperature, but can be turned into a dynamic covalent bond forming process at elevated temperatures, giving a reliable bond exchange or ‘transclick’ reaction. In this paper, we report an in-depth study aimed at controlling the TAD–indole reversible click reactions through rational design of modified indole reaction partners. This has resulted in the identification of a novel class of easily accessible indole derivatives that give dynamic TAD-adduct formation at significantly lower temperatures. We further demonstrate that these new substrates can be used to design a directed cascade of click reactions of a functionalized TAD moiety from an initial indole reaction partner to a second indole, and finally to an irreversible reaction partner. This controlled sequence of click and transclick reactions of a single TAD reagent between three different substrates has been demonstrated both on small molecule and macromolecular level, and the factors that control the reversibility profiles have been rationalized and guided by mechanistic considerations supported by theoretical calculations.

This article outlines the plans to develop a student midwife integrated learning environment (SMILE) which will focus upon the delivery of postnatal (PN) care to women and families whilst also creating an innovative clinical learning environment for students. The SMiLE PN hub (facilitated by student midwives, supervised by a qualified midwife/sign-off mentor) has been designed to fuse seamlessly with current PN provision and provide an alternative environment for women to access a wide range of PN services. This service proposal not only increases the amount of PN learning opportunities and experience of students but also provides a much needed hub of PN activity for women and their families. It provides drop-in breastfeeding support, signposting to additional support networks and scheduled daily parenting workshops, such as baby bathing and safe sleeping advice.

A study of the homogeneity and deviations from stoichiometry in mercuric iodide

We have been able to determine the deviations from stoichiometry of mercuric iodide (HgI 2) by using differential scanning calorimetry (DSC). Mercury excess or iodine deficiency in mercuric iodide can be evaluated from the eutectic melting of α-Hgl 2-Hg 2I 2 at 235 °C, which appears as an additional peak in DSC thermograms. I 2 excess can be found from the existence of the I 2-α-HgI 2 eutectic melting at 103°C. An additional DSC peak appears in some samples around 112°C, that could be explained by the presence of iodine inclusions. Using resonance fluorescence spectroscopy (RFS) we have been able to determine the presence of free I 2 that is released by samples during the heating at 120 °C (crystal growth temperature), thus giving additional support to the above DSC results.

A Single-Boundary Accumulator Model of Response Times in an Addition Verification Task

PubMed Central

Faulkenberry, Thomas J.

2017-01-01

Current theories of mathematical cognition offer competing accounts of the interplay between encoding and calculation in mental arithmetic. Additive models propose that manipulations of problem format do not interact with the cognitive processes used in calculation. Alternatively, interactive models suppose that format manipulations have a direct effect on calculation processes. In the present study, we tested these competing models by fitting participants' RT distributions in an arithmetic verification task with a single-boundary accumulator model (the shifted Wald distribution). We found that in addition to providing a more complete description of RT distributions, the accumulator model afforded a potentially more sensitive test of format effects. Specifically, we found that format affected drift rate, which implies that problem format has a direct impact on calculation processes. These data give further support for an interactive model of mental arithmetic. PMID:28769853

Patient support groups serve an important function for those affected by a disease but especially for people with a rare disease. Because of the complexity of Wilson disease there are some unique and difficult problems faced by groups that advocate for these patients. We give a comparative overview of the differences between groups that support people with more common diseases and groups that serve the rare disease population. The history and current status of the Wilson Disease Association and other worldwide Wilson disease groups are described and information about other organizations that support Wilson disease in additional ways is explained. The specific challenges faced in the support of Wilson disease patients are outlined and possible solutions proposed. Drawing from experience in speaking with many patients, we discuss some of the most common questions that are asked by patients who are seeking a possible diagnosis or are already on treatment. There are many options for improving patient advocacy efforts in the future that we hope will be accomplished. © 2017 Elsevier B.V. All rights reserved.

2014-08-01

Recognizing that students benefit when they receive autonomy-supportive teaching, the current study tested the parallel hypothesis that teachers themselves would benefit from giving autonomy support. Twenty-seven elementary, middle, and high school physical education teachers (20 males, 7 females) were randomly assigned either to participate in an autonomy-supportive intervention program (experimental group) or to teach their physical education course with their existing style (control group) within a three-wave longitudinal research design. Manipulation checks showed that the intervention was successful, as students perceived and raters scored teachers in the experimental group as displaying a more autonomy-supportive and less controlling motivating style. In the main analyses, ANCOVA-based repeated-measures analyses showed large and consistent benefits for teachers in the experimental group, including greater teaching motivation (psychological need satisfaction, autonomous motivation, and intrinsic goals), teaching skill (teaching efficacy), and teaching well-being (vitality, job satisfaction, and lesser emotional and physical exhaustion). These findings show that giving autonomy support benefits teachers in much the same way that receiving it benefits their students.

2008-12-01

The purpose of the study was to examine gender differences in the association between changes in the balance of give and take in close relationships and depressive symptoms. Data from a 5-year prospective cohort study in Finland (HeSSup Study) (N=18,445) were analyzed. After adjustment for demographic characteristics, recent negative life events, baseline depressive symptoms, hostility, and the supportiveness of social network, a shift of balance toward support receiving was a significant risk factor for future depressive symptoms among women. In contrast, men whose balance of give and take had moved toward support giving had a higher risk of future depressive symptoms than other men. When the analyses were replicated in a sub-cohort of initially non-depressed participants who lived in reciprocal relationships and had no recent life events, the results became even more pronounced among women, although not among men. We conclude that, for women, a shift in their close relationships toward support receiving may lead to increased risk of depressive symptoms, whereas for men a shift toward giving may have a parallel though less evident impact.

A collection has been made of additives that are required as analytical standards for enforcement of European Union legislation on food contact plastics. The 100 additives have been characterized by mass spectrometry, infra-red spectroscopy and proton nuclear magnetic resonance spectroscopy to provide reference spectra. Gas chromatographic retention times have been recorded to facilitate identification by retention index. This information has been further supplemented by physico-chemical data. Finally, chromatographic methods have been used to indicate the presence of any impurities in the commercial chemicals. Samples of the reference substances are available on request and the collection of spectra and other information will be made available in printed format and on-line through the Internet. This paper gives an overview of the work done to establish the reference collection and the spectral atlas, which together will assist enforcement laboratories in the characterization of plastics and the selection of analytical methods for additives that may migrate.

This review article gives an overview of the cell profiles of bronchoalveolar lavage and plasma samples during acute lung allograft rejection. The value of these cells and changes within the pattern of differential cytology to support the diagnosis of acute lung allograft rejection is discussed. Current findings on the topic are highlighted and trends for future research are identified.

In Orkney and Shetland, a survey of lifetime events was undertaken in multiple sclerosis patients and two control groups to define shared exposure to an exogenous agent or environmental insult. Analyses of demographic factors, diet, social class and occupation, housing and environment, animal exposure, schooling, travel, infectious disease, and medical history disclosed a remarkable similarity in responses between patients and controls for a majority of questions. However, differences were noted for sanitation, place of residence at onset, and animal exposure. The data give additional support for an exogenous aetiology of multiple sclerosis. PMID:7241023

On the regularized fermionic projector of the vacuum

NASA Astrophysics Data System (ADS)

Finster, Felix

2008-03-01

We construct families of fermionic projectors with spherically symmetric regularization, which satisfy the condition of a distributional MP-product. The method is to analyze regularization tails with a power law or logarithmic scaling in composite expressions in the fermionic projector. The resulting regularizations break the Lorentz symmetry and give rise to a multilayer structure of the fermionic projector near the light cone. Furthermore, we construct regularizations which go beyond the distributional MP-product in that they yield additional distributional contributions supported at the origin. The remaining freedom for the regularization parameters and the consequences for the normalization of the fermionic states are discussed.

Wordle has been commonly used to summarize texts, with each word size-coded by its frequency of occurrences--the more often a word occurs in texts, the bigger it is. The interactive authoring tool WordlePlus leverages natural interaction and animation to give users more control over wordle development. WordlePlus supports direct manipulation of words with pen and touch interaction. It introduces two-word multitouch manipulation, such as concatenating and grouping two words, and provides pen interaction for adding and deleting words. In addition, WordlePlus employs animation to help users create more dynamic and engaging wordles.

Examining the process of driving cessation in later life.

Driving cessation for many older people is associated with a poorer quality of life and can lead to health problems such as depression. This paper aims to reveal the process of giving-up driving, examining in particular triggers for giving-up driving, how information on alternative modes of transport is sought and how new transport and travel behaviour is integrated into older people's lives. It examines the challenges faced and how these are overcome and what impact the process has on self-reported quality of life, as articulated by the participants themselves. To this end, twenty-one individuals from three locations in the United Kingdom (UK) were followed over a period of 10 months, through five waves of data collection. Each participant took part in three interviews, a focus group and completed a diary of travel behaviour. Findings suggest that although a similar pattern was found between the trigger and life post-car, not all older people go through the stages of giving-up driving in the same way. Instead, a range of responses are seen, from contemplation of gradually reducing driving, through to stopping abruptly, with the route taken having consequences for the eventual outcome for any individual. Triggers for contemplating driving cessation could be varied and often involved health and social factors. Importantly, people who engaged in pre-planning reported a relatively higher quality of life beyond the car, whilst for those who were more reactive and engaged in little or no pre-planning a poorer quality of life resulted. In addition (and in conjunction with planning), other factors, such as flexibility in travel destinations, the role of family and friends, and wider support networks are also seen as important. With such evidence of the importance of pre-planning it is suggested that more could be done to support giving-up driving and encouraging contemplation at a younger age to mitigate the negative effects experienced by some.

Grantsmanship is an integral component of surviving and thriving in academic science, especially in the current funding climate. Therefore, any additional opportunities to write, read, and review grants during graduate school may have lasting benefits on one's career. We present here our experience with a small, student-run grant program at Georgetown University Medical Center. Founded in 2010, this program has several goals: 1) to give graduate students an opportunity to conduct small, independent research projects; 2) to encourage graduate students to write grants early and often; and 3) to give graduate students an opportunity to review grants. In the 3 yr since the program's start, 28 applications have been submitted, 13 of which were funded for a total of $40,000. From funded grants, students have produced abstracts and manuscripts, generated data to support subsequent grant proposals, and made new professional contacts with collaborators. Above and beyond financial support, this program provided both applicants and reviewers an opportunity to improve their writing skills, professional development, and understanding of the grants process, as reflected in the outcome measures presented. With a small commitment of time and funding, other institutions could implement a program like this to the benefit of their graduate students. PMID:24006391

A Model of Equilibrium Conditions of Roof Rock Mass Giving Consideration to the Yielding Capacity of Powered Supports

NASA Astrophysics Data System (ADS)

Jaszczuk, Marek; Pawlikowski, Arkadiusz

2017-12-01

The work presents the model of interactions between the powered roof support units and the rock mass, while giving consideration to the yielding capacity of the supports - a value used for the analysis of equilibrium conditions of roof rock mass strata in geological and mining conditions of a given longwall. In the model, the roof rock mass is kept in equilibrium by: support units, the seam, goafs, and caving rocks (Fig. 1). In the assumed model of external load on the powered roof support units it is a new development - in relation to the model applied in selection of supports based on the allowable deflection of roof theory - that the load bearing capacity is dependent on the increment of the inclination of the roof rock mass and on the properties of the working medium, while giving consideration to the air pockets in the hydraulic systems, the load of the caving rocks on the caving shield, introducing the RA support value of the roof rock mass by the coal seam as a closed-form expression and while giving consideration to the additional support provided by the rocks of the goaf as a horizontal component R01H of the goaf reaction. To determine the roof maintenance conditions it is necessary to know the characteristics linking the yielding capacity of the support units with the heading convergence, which may be measured as the inclination angle of the roof rock mass. In worldwide mining, Ground Reaction Curves are used, which allow to determine the required yielding capacity of support units based on the relation between the load exerted on the unit and the convergence of the heading ensuring the equilibrium of the roof rock mass. (Figs. 4 and 8). The equilibrium of the roof rock mass in given conditions is determined at the displacement of the rock mass by the α angle, which impacts the following values: yielding capacity of units FN, vertical component of goaf reaction R01V and the horizontal component of goaf reaction R01H. In the model of load on the support units giving consideration to the load of the caving shield, a model of support unit was used that allows for unequivocal determination of the yielding capacity of the support with consideration given to the height of the unit in use and the change in the inclination of the canopy resulting from the displacement of the roof of the longwall. The yielding capacity of the support unit and its point of application on the canopy was determined using the method of units which allows for the internal forces to be manifested. The weight of the rock mass depends on the geological and mining conditions, for which the shape and dimensions of the rock mass affecting the support unit are determined. The resultant force of the pressure of gob on the gob shield was calculated by assuming that the load may be understood as a pressure of ground on a wall. This required the specification of the volume of the fallen rocks that affect the unit of powered roof supports (Fig. 2). To determine the support of the roof rock mass by the coal seam, experience of the Australian mining industry was used. Experiments regarding the strength properties of coal have exhibited that vertical deformation, at which the highest seam reaction occurs while supporting the roof rock mass, amounts to 0.5% of the longwall's height. The measure of the width of the contact area between the rock mass and the seam is the width of the additional uncovering of the face roof due to spalling of seam topcorners da (Fig. 2). With the above parameters and the value of the modulus of elasticity of coal in mind, the value of the seam's reaction may be estimated using the dependence (2). The vertical component of the goafs' reaction may be determined based on the strength characteristics of the fallen roof, the contact area of the rock mass with the fallen roof and the mean strain of the fallen roof at the area of contact. In the work by Pawlikowski (2014), a research procedure was proposed which encompasses model tests and exploitation tests of the loads exerted on the support units, aimed at the determination of the vertical component of the goaf reaction (Fig. 5). Based on duty cycles of powered roof support units, a mean value of the indicator of contact stiffness between the roof rock mass and the rocks constituting the caving is determined, assuming the linear dependence between the horizontal reaction and the heading convergence. The parameter allows for the determination of the horizontal component of the goafs' reaction in the external loading model of support units and allows for the determination of the required yielding capacity of supports, required to ensure the equilibrium of the roof rock mass. The experimentally verified model of the external loading of the units was used to conduct simulations of interactions between the KOPEX-095/17-POz support unit and the rock mass in a face characterized by the height of 1.6 m. Based on the data obtained in experiment, the variability of the yielding capacity of the support units was analyzed. A yielding capacity inclination angle of the units was determined for the registered curves (Figs. 6 and 7). At the same time, the presentation of the lines corresponding to the required yielding capacity of units and characterizing the deformability of the support units, allows for the prediction of the yielding capacity of the powered supports and the convergence of the heading in the conditions of a given face (Fig. 9).

Austin, James A.; Grove, Timothy L.

2008-04-01

In the fall of 2007, the AGU Development Board commissioned the development staff to survey the approximately 1200 AGU supporting members to learn why these members give $100 to AGU each year- many give much more-to fund activities in education, public affairs, public information, the sections, and the focus groups. (A recent list of supporting members was published in Eos, 88(49), 544-545, 2007.) With supporting membership having more than doubled since 2003, the development staff and the Development Board wanted to find out more about the individual motivations underlying this trend. We also were trying to identify new incentives for members to support the Union's special projects and programs.

In Sweden degree projects have a central role in evaluation of higher education, wherefore significant resources are spent on developing students' research competence. The undergraduate medical program at Karolinska Institutet introduced its degree project course in 2010. This paper gives an overview of the course and summarizes experiences from the first seven terms. In order to finalize their projects within one term, most students need substantial support. A highly structured course and frequent progress monitoring are advantageous. Other crucial factors are the quality of the supervision and students' verbal skills as well as support in scientific writing. In addition, increased awareness of the learning outcomes already at the beginning of the course may help students to achieve the expected results. Finally, students need to recognize their own responsibility for learning.

The aim of this literature review is to assess the effectiveness of smoking cessation in managing patients with chronic obstructive pulmonary disease (COPD). COPD is the fifth leading cause of death in the world and smoking leads to COPD in more than 80% of cases. Smoking cessation aids are considered the most effective intervention to improve quality of life and prevent further deterioration in COPD. Evidence based on the use of pharmacotherapies, patient support and motivation as part of smoking cessation strategies were evaluated and discussed. The findings demonstrate that pharmacotherapies, support and counselling in smoking cessation help reduce hospital stay and hospitalisation and improve symptoms and quality of life. In addition, nurses need more education on how to use open-ended questions and motivation when giving advice on smoking cessation to patients with COPD.

PODIO: An Event-Data-Model Toolkit for High Energy Physics Experiments

Gaede, F.; Hegner, B.; Mato, P.

2017-10-01

PODIO is a C++ library that supports the automatic creation of event data models (EDMs) and efficient I/O code for HEP experiments. It is developed as a new EDM Toolkit for future particle physics experiments in the context of the AIDA2020 EU programme. Experience from LHC and the linear collider community shows that existing solutions partly suffer from overly complex data models with deep object-hierarchies or unfavorable I/O performance. The PODIO project was created in order to address these problems. PODIO is based on the idea of employing plain-old-data (POD) data structures wherever possible, while avoiding deep object-hierarchies and virtual inheritance. At the same time it provides the necessary high-level interface towards the developer physicist, such as the support for inter-object relations and automatic memory-management, as well as a Python interface. To simplify the creation of efficient data models PODIO employs code generation from a simple yaml-based markup language. In addition, it was developed with concurrency in mind in order to support the use of modern CPU features, for example giving basic support for vectorization techniques.

Farming is dangerous, with fatalities among the highest in any occupation. Farmers often work alone, for long hours, with unreliable equipment and in difficult weather conditions with hazardous chemicals and livestock. In addition, farmers make large financial commitments exposing them to high levels of financial risk. Exposure to such financial risk can give rise to subjective experiences of financial threat (FT) that are psychologically challenging. The current study attempted to characterize the role that FT plays in farm injuries. One hundred and twenty one dairy farmers completed a battery of questionnaires assessing FT, social support (SS), depression, anxiety, farm job stress, and health and safety beliefs. Mental distress directly predicted farmers' expectations of injury and a direct effect of non-financial farm stress (FS) approached significance. Mental distress mediated these relationships as evidenced by significant indirect effects of FS and FT, and SS served to reduce distress. These findings support calls for interventions designed to reduce FS and FT and increase SS for farmers.

Dynamic modeling for rigid rotor bearing systems with a localized defect considering additional deformations at the sharp edges

NASA Astrophysics Data System (ADS)

Liu, Jing; Shao, Yimin

2017-06-01

Rotor bearing systems (RBSs) play a very valuable role for wind turbine gearboxes, aero-engines, high speed spindles, and other rotational machinery. An in-depth understanding of vibrations of the RBSs is very useful for condition monitoring and diagnosis applications of these machines. A new twelve-degree-of-freedom dynamic model for rigid RBSs with a localized defect (LOD) is proposed. This model can formulate the housing support stiffness, interfacial frictional moments including load dependent and load independent components, time-varying displacement excitation caused by a LOD, additional deformations at the sharp edges of the LOD, and lubricating oil film. The time-varying displacement model is determined by a half-sine function. A new method for calculating the additional deformations at the sharp edges of the LOD is analytical derived based on an elastic quarter-space method presented in the literature. The proposed dynamic model is utilized to analyze the influences of the housing support stiffness and LOD sizes on the vibration characteristics of the rigid RBS, which cannot be predicted by the previous dynamic models in the literature. The results show that the presented method can give a new dynamic modeling method for vibration formulation for a rigid RBS with and without the LOD on the races.

NASA has a long range goal of constructing a fully equipped, manned lunar outpost on the near side of the moon by the year 2015. The proposed outpost includes an inflatable lunar habitat to support crews during missions longer that 12 months. A design for the internal support structures of the inflatable habitat is presented. The design solution includes material selection, substructure design, assembly plan development, and concept scale model construction. Alternate designs and design solutions for each component of the design are discussed. Alternate materials include aluminum, titanium, and reinforced polymers. Vertical support alternates include column systems, truss systems, suspension systems, and lunar lander supports. Horizontal alternates include beams, trusses, floor/truss systems, and expandable trusses. Feasibility studies on each alternate showed that truss systems and expandable trusses were the most feasible candidates for conceptual design. The team based the designs on the properties of 7075 T73 aluminum. The substructure assembly plan, minimizes assembly time and allows crews to construct the habitat without the use of EVA suits. In addition to the design solutions, the report gives conclusions and recommendations for further study of the inflatable habitat design.

Measurement of diffusion coefficients from solution rates of bubbles

NASA Technical Reports Server (NTRS)

Krieger, I. M.

1979-01-01

The rate of solution of a stationary bubble is limited by the diffusion of dissolved gas molecules away from the bubble surface. Diffusion coefficients computed from measured rates of solution give mean values higher than accepted literature values, with standard errors as high as 10% for a single observation. Better accuracy is achieved with sparingly soluble gases, small bubbles, and highly viscous liquids. Accuracy correlates with the Grashof number, indicating that free convection is the major source of error. Accuracy should, therefore, be greatly increased in a gravity-free environment. The fact that the bubble will need no support is an additional important advantage of Spacelab for this measurement.

Giving is receiving, and receiving is giving. This is the key finding from interviews conducted with 28 African American women and men with cancer who were active participants in dynamic relationships characterized by both giving and receiving. These participants engaged in reciprocal relationships varying in the number of persons involved, types of resources exchanged, and timing of exchange. Findings suggest the need to reconceptualize social support as caregiving and caregiving as social support. This study also points to the need to redesign intervention studies to be more inclusive of components that allow the elderly in illness-related situations to maintain their status as givers in their social networks.

Predicting Dynamic Postural Instability Using Center of Mass Time-to-Contact Information

Hasson, Christopher J.; Van Emmerik, Richard E.A.; Caldwell, Graham E.

2008-01-01

Our purpose was to determine whether spatiotemporal measures of center of mass motion relative to the base of support boundary could predict stepping strategies after upper-body postural perturbations in humans. We expected that inclusion of center of mass acceleration in such time-to-contact (TtC) calculations would give better predictions and more advanced warning of perturbation severity. TtC measures were compared with traditional postural variables, which don’t consider support boundaries, and with an inverted pendulum model of dynamic stability developed by Hof et al. (2005). A pendulum was used to deliver sequentially increasing perturbations to 10 young adults, who were strapped to a wooden backboard that constrained motion to sagittal plane rotation about the ankle joint. Subjects were instructed to resist the perturbations, stepping only if necessary to prevent a fall. Peak center of mass and center of pressure velocity and acceleration demonstrated linear increases with postural challenge. In contrast, boundary relevant minimum TtC values decreased nonlinearly with postural challenge, enabling prediction of stepping responses using quadratic equations. When TtC calculations incorporated center of mass acceleration, the quadratic fits were better and gave more accurate predictions of the TtC values that would trigger stepping responses. In addition, TtC minima occurred earlier with acceleration inclusion, giving more advanced warning of perturbation severity. Our results were in agreement with TtC predictions based on Hof’s model, and suggest that TtC may function as a control parameter, influencing the postural control system’s decision to transition from a stationary base of support to a stepping strategy.

This study examines the moderating role of emotional communication competence in the relationship between computer-mediated social support (CMSS) group participation, specifically giving and receiving emotional support, and psychological health outcomes. Data were collected as part of randomized clinical trials for women diagnosed with breast cancer within the last 2 months. Expression and reception of emotional support was assessed by tracking and coding the 18,064 messages that 236 patients posted and read in CMSS groups. The final data used in the analysis was created by merging (a) computer-aided content analysis of discussion posts, (b) action log data analysis of system usage, and (c) baseline and six-month surveys collected to assess change. Results of this study demonstrate that emotional communication competence moderates the effects of expression and reception of emotional support on psychological quality of life and breast cancer-related concerns in both desired and undesired ways. Giving and receiving emotional support in CMSS groups has positive effects on emotional well-being for breast cancer patients with higher emotional communication, while the same exchanges have detrimental impacts on emotional well-being for those with lower emotional communication competence. The theoretical and practical implications for future research are discussed. PMID:24058261

Grapheme-colour synaesthesia yields an ordinary rather than extraordinary memory advantage: evidence from a group study.

PubMed

Rothen, Nicolas; Meier, Beat

2010-04-01

In synaesthesia, the input of one sensory modality automatically triggers an additional experience, not normally triggered by the input of that modality. Therefore, compared to non-synaesthetes, additional experiences exist and these may be used as retrieval cues when memory is tested. Previous case studies have suggested that synaesthesia may yield even extraordinary memory abilities. However, group studies found either a task-specific memory advantage or no performance advantage at all. The aim of the present study was to test whether grapheme-colour synaesthesia gives rise to a general memory benefit using a standardised memory test (Wechsler Memory Scale). The synaesthetes showed a performance advantage in episodic memory tests, but not in short-term memory tests. However, performance was still within the ordinary range. The results support the hypothesis that synaesthesia provides for a richer world of experience and as a consequence additional retrieval cues may be available and beneficial but not to the point of extraordinary memory ability.

Importance of social capital at the workplace for return to work among women with a history of long-term sick leave: a cohort study.

The workplace is an essential source of social capital for many people; it provides mutual support and gives meaning to life. However, few prospective studies have thoroughly investigated the importance of aspects of social capital in the workplace. The aim of this study was to investigate the associations between aspects of social capital (social support, sense of community, and quality of leadership) at the workplace, and work ability, working degree, and vitality among women with a history of long-term sick leave from human service organizations. A longitudinal cohort study was performed among women with a history of long-term sick leave. The study started in 2005, and the women were followed up at 6 months, 1 year, and 6 years using self-reported questionnaires (baseline n  = 283). Linear mixed models were used for longitudinal analysis of the repeated measurements of prospective degree of work ability, working degree, and vitality. Analyses were performed with different models; the explanatory variables for each model were social support, sense of community, and quality of leadership and time. Social capital in terms of quality of leadership (being good at solving conflicts and giving high priority to job satisfaction), sense of community (co-operation between colleagues) and social support (help and support from immediate superiors and colleagues) increased the women's work ability score (WAS) as well as working degree over time. Additionally, social capital in terms of quality of leadership increased the women's vitality score over time. A sustainable return-to-work process among individuals with a history of long-term sick leave, going in and out of work participation, could be supported with social support, good quality of leadership, and a sense of community at the workplace. The responsibility for the rehabilitation process can not be reduced to an individual problem, but ought to include all stakeholders involved in the process, such as managers, colleagues, health care services, and the social security agency.

In this work we present the design and implementation of WARCProcessor, a novel multiplatform integrative tool aimed to build scientific datasets to facilitate experimentation in web spam research. The developed application allows the user to specify multiple criteria that change the way in which new corpora are generated whilst reducing the number of repetitive and error prone tasks related with existing corpus maintenance. For this goal, WARCProcessor supports up to six commonly used data sources for web spam research, being able to store output corpus in standard WARC format together with complementary metadata files. Additionally, the application facilitates the automatic and concurrent download of web sites from Internet, giving the possibility of configuring the deep of the links to be followed as well as the behaviour when redirected URLs appear. WARCProcessor supports both an interactive GUI interface and a command line utility for being executed in background.

In legal medicine the correct determination of the time of death is of utmost importance. Recent advances in estimating post-mortem interval (PMI) have made use of vitreous humour chemistry in conjunction with Linear Regression, but the results are questionable. In this paper we present PMICALC, an R code-based freeware package which estimates PMI in cadavers of recent death by measuring the concentrations of potassium ([K+]), hypoxanthine ([Hx]) and urea ([U]) in the vitreous humor using two different regression models: Additive Models (AM) and Support Vector Machine (SVM), which offer more flexibility than the previously used Linear Regression. The results from both models are better than those published to date and can give numerical expression of PMI with confidence intervals and graphic support within 20 min. The program also takes into account the cause of death. 2009 Elsevier Ireland Ltd. All rights reserved.

Visual Support System for Report Distinctiveness Evaluation

NASA Astrophysics Data System (ADS)

Sunayama, Wataru; Kawaguchi, Toshiaki

In recent years, as the Internet has grown, electronic reports have come to be used in educational organizations such as universities. Though reports written by hand must be evaluated by hand except for stereotype descriptions or numerical answers, electronic reports can be rated by computer. There are two major criteria in rating reports, correctness and distinctiveness. Correctness is rated by absolute criteria and distinctiveness is rated by relative criteria. Relative evaluation is difficult because raters should memorize all contents of submitted reports to provide objective rates. In addition, electronic data are easily copied or exchanged by students. This paper presents a report evaluation support system with which raters can compare each report and give objective rates for distinctiveness. This system evaluates each report by objective similarity criteria and visualizes them in a two-dimensional interface as the calculated distinctiveness order. Experimental results show the system is valid and effective for estimating associations between reports.

A review is given of the work we presented in the 1990s that successfully developed a technique for reproducing the surface patterns and internal microstructure of genuine Damascus steel blades. That work showed that a key factor in making these blades was the addition of quite small levels of carbide-forming elements, notably V. Experiments are presented for blades made from slow- and fast-cooled ingots, and the results support our previous hypothesis that the internal banded microstructure results from microsegregation of V between dendrites during ingot solidification. A hypothetical model was presented for the mechanism causing the unique internal microstructure that gives rise to the surface pattern forming during the forging of the ingots from which the blades are made. This article attempts to explain the model more clearly and presents some literature data that offer support to the model. It also discusses an alternate model recently proposed by Foll.

Detecting disruptions with sufficient anticipation time is essential to undertake any form of remedial strategy, mitigation or avoidance. Traditional predictors based on machine learning techniques can be very performing, if properly optimised, but do not provide a natural estimate of the quality of their outputs and they typically age very quickly. In this paper a new set of tools, based on probabilistic extensions of support vector machines (SVM), are introduced and applied for the first time to JET data. The probabilistic output constitutes a natural qualification of the prediction quality and provides additional flexibility. An adaptive training strategy ‘from scratch’ has also been devised, which allows preserving the performance even when the experimental conditions change significantly. Large JET databases of disruptions, covering entire campaigns and thousands of discharges, have been analysed, both for the case of the graphite and the ITER Like Wall. Performance significantly better than any previous predictor using adaptive training has been achieved, satisfying even the requirements of the next generation of devices. The adaptive approach to the training has also provided unique information about the evolution of the operational space. The fact that the developed tools give the probability of disruption improves the interpretability of the results, provides an estimate of the predictor quality and gives new insights into the physics. Moreover, the probabilistic treatment permits to insert more easily these classifiers into general decision support and control systems.

Impacts of care-giving and sources of support: a comparison of end-of-life and non-end-of-life caregivers in Canada.

This is the second in a series of papers that deal with care-giving in Canada, as based on data available from the Canadian General Social Survey (2007). Building on the first paper, which reviewed the differences between short-term, long-term and end-of-life (EOL) caregivers, this paper uniquely examines the caregiver supports employed by EOL caregivers when compared to non-EOL caregivers (short-term and long-term caregivers combined). Both papers employ data from Statistics Canada's General Social Survey (GSS Cycle 21: 2007). The GSS includes three modules, where respondents were asked questions about the unpaid home care assistance that they had provided in the last 12 months to someone at EOL or with either a long-term health condition or a physical limitation. The objective of this research paper was to investigate the link between the impact of the care-giving experience and the caregiver supports received, while also examining the differences in these across EOL and non-EOL caregivers. By way of factor analysis and regression modelling, we examine differences between two types of caregivers: (i) EOL and (ii) non-EOL caregivers. The study revealed that with respect to socio-demographic characteristics, health outcomes and caregiver supports, EOL caregivers were consistently worse off. This suggests that although all non-EOL caregivers are experiencing negative impacts from their care-giving role, comparatively greater supports are needed for EOL caregivers. © 2015 The Authors.

Zinc complexes supported by methyl salicylato ligands: synthesis, structure, and application in ring-opening polymerization of L-lactide.

PubMed

Petrus, Rafał; Sobota, Piotr

2013-10-14

Two novel zinc alkoxides supported by chelating methyl salicylato (MesalO; MesalOH = methyl salicylate) ligands were successfully synthesized and characterized. Reaction of MesalOH with ZnEt2 (2:1) gives a tetranuclear cluster [Zn(MesalO)2]4 (1), which by addition of pyridine is transformed to the mononuclear compound [Zn(MesalO)2(py)2] (2). Compounds 1 and 2 were characterized by elemental analysis, NMR, IR, and single crystal X-ray diffraction. The catalytic activity of both compounds was tested for the ring-opening polymerization (ROP) of L-lactide (L-LA). It was found that compounds 1 and 2 are efficient initiators of the ROP of L-LA, yielding cyclic PLLA with weight average molecular weights up to 100 kDa for 2. The treatment of 2 with 1 equiv. of BnOH in toluene afforded a dimeric compound [Zn(OBn)(MesalO)(py)]2 (3). The addition of L-LA to a combination of 1 and 4 equiv. of BnOH in THF or 2 and 1 equiv. of BnOH in toluene led to the rapid and efficient generation of PLLA with end-capped BnO groups.

We report on a 12-year-old Brazilian boy with the p.Pro49Arg mutation in PPP1CB, a novel gene associated with RASopathies. This is the fifth individual described, and the fourth presenting the same variant, suggesting a mutational hotspot. Phenotypically, he also showed the same hair pattern-sparse, thin, and with slow growing-, similar to the typical ectodermal finding observed in Noonan syndrome-like disorder with loose anagen hair. Additionally, he presented craniosynostosis, a rare clinical finding in RASopathies. This report gives further support that this novel RASopathy-PPP1CB-related Noonan syndrome with loose anagen hair-shares great similarity to Noonan syndrome-like disorder with loose anagen hair, and expands the phenotypic spectrum by adding the cranial vault abnormality. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Azlactones participate in stereoselective reactions with electron-deficient alkenes and N-sulfonyl aldimines to give products of 1,3-dipolar cycloaddition and Mannich addition reactions respectively. Both of these reactions proceed with good to excellent diastereo- and enantioselectivity using a single class of gold-catalysts, namely C2-symmetric bis(phosphinegold(I) carboxylate)complexes. The development of the azlactone Mannich reaction to provide fully protected anti-α,β-diamino acid derivatives is described. 1,3-Dipolar cycloaddition reactions of several acyclic 1,2-disubstituted alkenes, and the chemistry of the resultant cycloadducts, are examined to probe the stereochemical course of this reaction. Reaction kinetics and tandem MS studies of both the cycloaddition and Mannich reactions are reported. These studies support a mechanism in which the gold complexes catalyze addition reactions through nucleophile activation rather than the more typical activation of the electrophilic reaction component.

Co-arrays in the Next Fortran Standard

DOE PAGES

Reid, John; Numrich, Robert W.

2007-01-01

The WG5 committee, at its meeting in Delft, May 2005, decided to include co-arrays in the next Fortran Standard. A Fortran program containing co-arrays is interpreted as if it were replicated a fixed number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is called an image. The array syntax of Fortran is extended with additional trailing subscripts in square brackets to give a clear and straightforward representation of access to data on other images. References without square brackets are to local data, so code that can run independently is uncluttered.more » Any occurrence of square brackets is a warning about communication between images. The additional syntax requires support in the compiler, but it has been designed to be easy to implement and to give the compiler scope both to apply its optimizations within each image and to optimize the communication between images. The extension includes execution control statements for synchronizing images and intrinsic procedures to return the number of images, to return the index of the current image, and to perform collective operations. The paper does not attempt to describe the full details of the feature as it now appears in the draft of the new standard. Instead, we describe a subset and demonstrate the use of this subset with examples.« less

Care-giving as a Canadian-Vietnamese tradition: ‘It's like eating, you just do it’

Donovan, Rhonda; Williams, Allison M

2015-01-01

The objective of this study was to examine how Vietnamese family caregivers (FCGs) perceive, manage and experience end-of-life care-giving for seriously ill family members. Using an instrumental case study design, this longitudinal qualitative research employed the use of cultural brokers/language interpreters to help ensure that the research was conducted in a culturally-appropriate manner. Participants (n = 18) discussed their experiences of care-giving within the context of a traditional cultural framework, which was found to influence their motivations and approaches to care-giving, as well as their propensities towards the use of various supports and services. The study was carried out in southern Ontario, Canada, and participants were providing home-based care-giving in the community. Data were collected throughout 2010 and 2011. The ways in which care-giving was perceived and expressed are reflected in three themes: (i) Natural: identity and care work; (ii) Intentional: whole-person care; and (iii) Intensive: standards, struggle and the context of care. This research confirms the need for culturally-appropriate services and supports while illustrating that Vietnamese FCGs not only value, but are also likely to use healthcare and social services if they are language-accessible, built on trust and demonstrate respect for their values as individuals, regardless of culture.

There is a lack of online, evidence-based information and resources to support home-based care of childhood CKD stages 3-5. Qualitative interviews were undertaken with parents, patients and professionals to explore their views on content of the proposed online parent information and support (OPIS) web-application. Data were analysed using Framework Analysis, guided by the concept of Self-efficacy. 32 parents, 26 patients and 12 professionals were interviewed. All groups wanted an application that explains, demonstrates, and enables parental clinical care-giving, with condition-specific, continously available, reliable, accessible material and a closed communication system to enable contact between families living with CKD. Professionals advocated a regularly updated application to empower parents to make informed health-care decisions. To address these requirements, key web-application components were defined as: (i) Clinical care-giving support (information on treatment regimens, video-learning tools, condition-specific cartoons/puzzles, and a question and answer area) and (ii) Psychosocial support for care-giving (social-networking, case studies, managing stress, and enhancing families' health-care experiences). Developing a web-application that meets parents' information and support needs will maximise its utility, thereby augmenting parents' self-efficacy for CKD caregiving, and optimising outcomes. Self-efficacy theory provides a schema for how parents' self-efficacy beliefs about management of their child's CKD could potentially be promoted by OPIS.

The role of 'social support' in the experience of fibromyalgia - narratives from South Africa.

PubMed

Cooper, Silvie; Gilbert, Leah

2017-05-01

This paper focuses on the role of 'social support' in the experience of fibromyalgia (a musculoskeletal pain disorder) in South Africa. In-depth semi-structured interviews were used to collect narratives from 15 participants. Sources of social support constitute important mechanisms for coping with the illness experience of fibromyalgia. In providing a space for consultation and validation of the diagnosis of fibromyalgia, and the person living with the condition, people giving support fulfil a critical role in shaping the experience. The findings show how support from family, partners, and peers plays an integral role in the process of accepting fibromyalgia diagnosis, adapting to the demands of the condition, and seeking help from healthcare providers. The findings also show the ways in which people with fibromyalgia provide support for others with the condition, and the importance of this peer network in shaping the paths and outcomes of this illness experience. The findings of this study corroborate existing evidence that show fibromyalgia to be a complex condition to manage, due to the multiplicity, uncertainty and contestation that feature in the experience of the illness. Additionally, this study presents the challenges related to the limitations of access to healthcare in the South African context, and the utility of narrative approaches in garnering insight into the ways in which social support is harnessed in this environment. © 2016 John Wiley & Sons Ltd.

Meeting unmet needs of families of persons with mental illness: evaluation of a family peer support helpline.

Family members of persons with mental illness experience multiple stressors stemming from the burdens of caring for the ill family member. A potential source of help for this population is a family peer support helpline. Knowledge, however, is lacking about the types of help offered in such a service and its benefit for this population. In a study conducted in Israel, 800 calls made by family members of persons with mental illness to a family peer support helpline were analyzed utilizing an instrument developed for the family peers' evaluation of the calls. In addition, researchers conducted 77 follow-up interviews with callers who agreed to be interviewed. The findings indicate the importance of the life experience, flexibility and anonymity of the family peers in providing types of help that are complementary to the help provided by formal services. The most frequent categories of support provided were emotional support, information and advice. This help could assist family members of persons with mental illness with their care-giving role, as well as provide them with an alternative source of help if they experience difficulties with professionals. It could also serve as a catalyst in encouraging them to establish and maintain contact with the formal mental health services. Recognizing and supporting the contribution of a family peer support helpline would encourage its development within the range of services available for this population.

Obesity during pregnancy is increasing and is related to life-threatening and ill-health conditions in both mother and child. Initiating and maintaining a healthy lifestyle when pregnant with body mass index (BMI) ≥ 30 kg/m(2) can improve health and decrease risks during pregnancy and of long-term illness for the mother and the child. To minimise gestational weight gain women with BMI ≥ 30 kg/m(2) in early pregnancy were invited to a lifestyle intervention including advice and support on diet and physical activity in Gothenburg, Sweden. The aim of this study was to explore the experiences of women with BMI ≥ 30 kg/m(2) regarding minimising their gestational weight gain, and to assess how health professionals' care approaches are reflected in the women's narratives. Semi-structured interviews were conducted with 17 women who had participated in a lifestyle intervention for women with BMI ≥ 30 kg/m(2) during pregnancy 3 years earlier. The interviews were digitally recorded and transcribed in full. Thematic analysis was used. The meaning of changing lifestyle for minimising weight gain and of the professional's care approaches is described in four themes: the child as the main motivation for making healthy changes; a need to be seen and supported on own terms to establish healthy routines; being able to manage healthy activities and own weight; and need for additional support to maintain a healthy lifestyle. To support women with BMI ≥ 30 kg/m(2) to make healthy lifestyle changes and limit weight gain during pregnancy antenatal health care providers should 1) address women's weight in a non-judgmental way using BMI, and provide accurate and appropriate information about the benefits of limited gestational weight gain; 2) support the woman on her own terms in a collaborative relationship with the midwife; 3) work in partnership to give the woman the tools to self-manage healthy activities and 4) give continued personal support and monitoring to maintain healthy eating and regular physical activity habits after childbirth involving also the partner and family.

In addition to personnel challenges,faith-based organizations (FBOs) face tangible challenges to implementing tobacco use prevention programs, such as finding materials that fit within their mission and financial backing to support the program. The present project surveyed 71 FBO leaders about these challenges with two open-ended questions that asked what would help and hinder them from delivering a tobacco prevention program, and Likert questionnaires on advocacy, efficacy, impact, policy, burnout, and morality. On what would help them deliver a tobacco prevention program, the most common answer was materials; about half of present FBO leaders gave this answer. On what would interfere, the most common answer was nothing, with about one quarter giving this answer; and, the next most common answer was not having materials with about one sixth giving this answer. The survey was brief (2 pages), and the sample size was small (71). Having the appropriate tobacco prevention materials was clearly a concern for present, mostly African American faith-based leaders, who reported that they needed materials more than they needed money, volunteers, or other forms of assistance.

Algorithmic and user study of an autocompletion algorithm on a large medical vocabulary.

Sevenster, Merlijn; van Ommering, Rob; Qian, Yuechen

2012-02-01

Autocompletion supports human-computer interaction in software applications that let users enter textual data. We will be inspired by the use case in which medical professionals enter ontology concepts, catering the ongoing demand for structured and standardized data in medicine. Goal is to give an algorithmic analysis of one particular autocompletion algorithm, called multi-prefix matching algorithm, which suggests terms whose words' prefixes contain all words in the string typed by the user, e.g., in this sense, opt ner me matches optic nerve meningioma. Second we aim to investigate how well it supports users entering concepts from a large and comprehensive medical vocabulary (snomed ct). We give a concise description of the multi-prefix algorithm, and sketch how it can be optimized to meet required response time. Performance will be compared to a baseline algorithm, which gives suggestions that extend the string typed by the user to the right, e.g. optic nerve m gives optic nerve meningioma, but opt ner me does not. We conduct a user experiment in which 12 participants are invited to complete 40 snomed ct terms with the baseline algorithm and another set of 40 snomed ct terms with the multi-prefix algorithm. Our results show that users need significantly fewer keystrokes when supported by the multi-prefix algorithm than when supported by the baseline algorithm. The proposed algorithm is a competitive candidate for searching and retrieving terms from a large medical ontology. Copyright © 2011 Elsevier Inc. All rights reserved.

DNA mutation binding proteins alone and as chimeric proteins with nucleases are used with solid supports to detect DNA sequence variations, DNA mutations and single nucleotide polymorphisms. The solid supports may be flow cytometry beads, DNA chips, glass slides or DNA dips sticks. DNA molecules are coupled to solid supports to form DNA-support complexes. Labeled DNA is used with unlabeled DNA mutation binding proteins such at TthMutS to detect DNA sequence variations, DNA mutations and single nucleotide length polymorphisms by binding which gives an increase in signal. Unlabeled DNA is utilized with labeled chimeras to detect DNA sequence variations, DNA mutations and single nucleotide length polymorphisms by nuclease activity of the chimera which gives a decrease in signal.

This paper aims to predict childhood obesity after age two, using only data collected prior to the second birthday by a clinical decision support system called CHICA. Analyses of six different machine learning methods: RandomTree, RandomForest, J48, ID3, Naïve Bayes, and Bayes trained on CHICA data show that an accurate, sensitive model can be created. Of the methods analyzed, the ID3 model trained on the CHICA dataset proved the best overall performance with accuracy of 85% and sensitivity of 89%. Additionally, the ID3 model had a positive predictive value of 84% and a negative predictive value of 88%. The structure of the tree also gives insight into the strongest predictors of future obesity in children. Many of the strongest predictors seen in the ID3 modeling of the CHICA dataset have been independently validated in the literature as correlated with obesity, thereby supporting the validity of the model. This study demonstrated that data from a production clinical decision support system can be used to build an accurate machine learning model to predict obesity in children after age two.

The Roles of Financial Threat, Social Support, Work Stress, and Mental Distress in Dairy Farmers’ Expectations of Injury

Farming is dangerous, with fatalities among the highest in any occupation. Farmers often work alone, for long hours, with unreliable equipment and in difficult weather conditions with hazardous chemicals and livestock. In addition, farmers make large financial commitments exposing them to high levels of financial risk. Exposure to such financial risk can give rise to subjective experiences of financial threat (FT) that are psychologically challenging. The current study attempted to characterize the role that FT plays in farm injuries. One hundred and twenty one dairy farmers completed a battery of questionnaires assessing FT, social support (SS), depression, anxiety, farm job stress, and health and safety beliefs. Mental distress directly predicted farmers’ expectations of injury and a direct effect of non-financial farm stress (FS) approached significance. Mental distress mediated these relationships as evidenced by significant indirect effects of FS and FT, and SS served to reduce distress. These findings support calls for interventions designed to reduce FS and FT and increase SS for farmers. PMID:27446893

WFIRST Science Operations at STScI

With sensitivity and resolution comparable the Hubble Space Telescope, and a field of view 100 times larger, the Wide Field Instrument (WFI) on WFIRST will be a powerful survey instrument. STScI will be the Science Operations Center (SOC) for the WFIRST Mission, with additional science support provided by the Infrared Processing and Analysis Center (IPAC) and foreign partners. STScI will schedule and archive all WFIRST observations, calibrate and produce pipeline-reduced data products for imaging with the Wide Field Instrument, support the High Latitude Imaging and Supernova Survey Teams, and support the astronomical community in planning WFI imaging observations and analyzing the data. STScI has developed detailed concepts for WFIRST operations, including a data management system integrating data processing and the archive which will include a novel, cloud-based framework for high-level data processing, providing a common environment accessible to all users (STScI operations, Survey Teams, General Observers, and archival investigators). To aid the astronomical community in examining the capabilities of WFIRST, STScI has built several simulation tools. We describe the functionality of each tool and give examples of its use.

Coordination of dual robot arms using kinematic redundancy

NASA Technical Reports Server (NTRS)

Suh, Il Hong; Shin, Kang G.

1988-01-01

A method is developed to coordinate the motion of dual robot arms carrying a solid object, where the first robot (leader) grasps one end of the object rigidly and the second robot (follower) is allowed to change its grasping position at the other end of the object along the object surface while supporting the object. It is shown that this flexible grasping is equivalent to the addition of one more degree of freedom (dof), giving the follower more maneuvering capabilities. In particular, motion commands for the follower are generated by using kinematic redundancy. To show the utility and power of the method, an example system with two PUMA 560 robots carrying a beam is analyzed.

Cost shifting revisited: the case of service intensity.

PubMed

Friesner, Daniel L; Rosenman, Robert

2002-02-01

This paper examines whether a health care provider's choice of service intensity for any patient group affects its cost shifting behavior. Our theoretical models indicate that firms may respond to lower prospective payment by decreasing service intensity to all of its patient groups, thereby giving firms an alternative to cost shifting. Additionally, the conditions under which cost shifting and lower service intensity occur are identical, regardless of profit status. Using a panel of California hospitals, we found that nonprofit hospitals do cost shift, while profit-maximizing hospitals do not. However, both firms respond to lower prospective payment by decreasing service intensity, thus supporting our theoretical conclusion that lower service intensity can be used as an alternative to cost shifting.

The wind process is essential for hydrometeorology and additionally, is one of the basic renewable energy resources. Most stochastic forecast models are limited up to daily scales disregarding the hourly scale which is significant for renewable energy management. Here, we analyze hourly wind timeseries giving emphasis on the temporal distribution of wind within the day. We finally present a periodic model based on statistical as well as hydrometeorological reasoning that shows good agreement with data.

1997-01-01

We present a systematic discussion of algorithms to multiply a vector by a matrix expressed as the Kronecker product of sparse matrices, extending previous work in a unified notational framework. Then, we use our results to define new algorithms for the solution of large structured Markov models. In addition to a comprehensive overview of existing approaches, we give new results with respect to: (1) managing certain types of state-dependent behavior without incurring extra cost; (2) supporting both Jacobi-style and Gauss-Seidel-style methods by appropriate multiplication algorithms; (3) speeding up algorithms that consider probability vectors of size equal to the "actual" state space instead of the "potential" state space.

In addition to its energy storage function, the system can supply hydrogen and oxygen for attitude control of the satellite and for life support. A summary is presented of the results to date obtained in connection with the NASA-sponsored fuel cell technology advancement program, giving particular attention to the requirements of the alkaline regenerative fuel cell and the low-earth mission. Attention is given to system design guidelines, weight considerations, gold-platinum cathode cell performance, matrix development, the electrolyte reservoir plate, and the cyclical load profile tests.

Channel surface plasmons in a continuous and flat graphene sheet

NASA Astrophysics Data System (ADS)

Chaves, A. J.; Peres, N. M. R.; da Costa, D. R.; Farias, G. A.

2018-05-01

We derive an integral equation describing surface-plasmon polaritons in graphene deposited on a substrate with a planar surface and a dielectric protrusion in the opposite surface of the dielectric slab. We show that the problem is mathematically equivalent to the solution of a Fredholm equation, which we solve exactly. In addition, we show that the dispersion relation of the channel surface plasmons is determined by the geometric parameters of the protrusion alone. We also show that such a system supports both even and odd modes. We give the electrostatic potential and the intensity plot of the electrostatic field, which clearly show the transverse localized nature of the surface plasmons in a continuous and flat graphene sheet.

Improving return-to-work after childbirth: design of the Mom@Work study, a randomised controlled trial and cohort study.

Many women suffer from health problems after giving birth, which can lead to sick leave. About 30% of Dutch workers are on sick leave after maternity leave. Structural contact of supervisors with employees on maternity leave, supported by early medical advice of occupational physicians, may increase the chances of return-to-work after maternity leave. In addition, to understand the process of sick leave and return-to-work after childbirth it is important to gain insight into which factors hinder return-to-work after childbirth, as well, as which prognostic factors lead to the development of postpartum health complaints. In this paper, the design of the Mom@Work study is described. The Mom@Work study is simultaneously a randomised controlled trial and a cohort study. Pregnant women working for at least 12 hours a week at one of the 15 participating companies are eligible to participate. The supervisors of these pregnant employees are randomised at 35 weeks pregnancy into the intervention group or control group. During maternity leave, supervisors in the intervention group contact their employee six weeks after delivery using a structured interview. When employees do not expect to return to their jobs at the end of their scheduled maternity leave due to health problems, the supervisor offers early support of the occupational physician. Supervisors in the control group have no structural contact with their employees during maternity leave. Measurements take place at 30 weeks pregnancy and at 6, 12, 24 and 52 weeks postpartum. In addition, cost data are collected. For the RCT, primary outcome measures are sick leave and return-to-work, and secondary outcome measures are costs, health, satisfaction with intervention and global feelings of recovery. Outcome measures for the cohort are pregnancy-related pelvic girdle pain, fatigue and depression. Finally, a number of prognostic factors for return-to-work and for the development of complaints will be measured. The Mom@Work study will provide important information about return-to-work of employees after giving birth. Results will give insight in prognosis of postpartum sick leave and complaints. Also, the role of supervisors and occupational physicians in successful return-to-work after childbirth will be clarified.

Component-Based Visualization System

NASA Technical Reports Server (NTRS)

Delgado, Francisco

2005-01-01

A software system has been developed that gives engineers and operations personnel with no "formal" programming expertise, but who are familiar with the Microsoft Windows operating system, the ability to create visualization displays to monitor the health and performance of aircraft/spacecraft. This software system is currently supporting the X38 V201 spacecraft component/system testing and is intended to give users the ability to create, test, deploy, and certify their subsystem displays in a fraction of the time that it would take to do so using previous software and programming methods. Within the visualization system there are three major components: the developer, the deployer, and the widget set. The developer is a blank canvas with widget menu items that give users the ability to easily create displays. The deployer is an application that allows for the deployment of the displays created using the developer application. The deployer has additional functionality that the developer does not have, such as printing of displays, screen captures to files, windowing of displays, and also serves as the interface into the documentation archive and help system. The third major component is the widget set. The widgets are the visual representation of the items that will make up the display (i.e., meters, dials, buttons, numerical indicators, string indicators, and the like). This software was developed using Visual C++ and uses COTS (commercial off-the-shelf) software where possible.

Properties of Ti-6Al-4V spun formed fuze supports

DOE Office of Scientific and Technical Information (OSTI.GOV)

Moody, N.R.; Gates, G.

1985-05-01

Spin forming is designated as the primary fabrication process for the Ti-6A1-4V, W-87 fuze support. This process reduces the amount of rough machining during production, the cost of the starting material and the lead time from order to delivery of finished parts compared with parts made from forgings. However, because the amount of deformation from the spin forming process varies greatly within the part, the properties resulting from spin forming the fuze supports are unknown. This study shows that the properties and microstructure of the highly deformed walls of the fuze support are similar to those of forgings, while themore » properties and microstructure of the lightly deformed nose are similar to those of the parent plate. A solution treatment at 1750/sup 0/F/1h/WQ (954/sup 0/C) followed by a 900/sup 0/F (482/sup 0/C) four hour age gives the desired properties. Additionally, microstructural evaluation shows that the temperatures during spin forming are maintained within desired limits and that no significant microstructural changes occur during subsequent elevated temperature processing of the finished part. This study shows that solution treated and aged parts meet all required properties for all conditions to which the fuze supports will be subjected.« less

Identification and characterization of mouse otic sensory lineage genes

Hartman, Byron H.; Durruthy-Durruthy, Robert; Laske, Roman D.; Losorelli, Steven; Heller, Stefan

2015-01-01

Vertebrate embryogenesis gives rise to all cell types of an organism through the development of many unique lineages derived from the three primordial germ layers. The otic sensory lineage arises from the otic vesicle, a structure formed through invagination of placodal non-neural ectoderm. This developmental lineage possesses unique differentiation potential, giving rise to otic sensory cell populations including hair cells, supporting cells, and ganglion neurons of the auditory and vestibular organs. Here we present a systematic approach to identify transcriptional features that distinguish the otic sensory lineage (from early otic progenitors to otic sensory populations) from other major lineages of vertebrate development. We used a microarray approach to analyze otic sensory lineage populations including microdissected otic vesicles (embryonic day 10.5) as well as isolated neonatal cochlear hair cells and supporting cells at postnatal day 3. Non-otic tissue samples including periotic tissues and whole embryos with otic regions removed were used as reference populations to evaluate otic specificity. Otic populations shared transcriptome-wide correlations in expression profiles that distinguish members of this lineage from non-otic populations. We further analyzed the microarray data using comparative and dimension reduction methods to identify individual genes that are specifically expressed in the otic sensory lineage. This analysis identified and ranked top otic sensory lineage-specific transcripts including Fbxo2, Col9a2, and Oc90, and additional novel otic lineage markers. To validate these results we performed expression analysis on select genes using immunohistochemistry and in situ hybridization. Fbxo2 showed the most striking pattern of specificity to the otic sensory lineage, including robust expression in the early otic vesicle and sustained expression in prosensory progenitors and auditory and vestibular hair cells and supporting cells.

The small exciton mass and binding energy give the opportunity to realize the high magnetic field regime for excitons in magnetic fields of few Tesla achievable in lab Long lifetimes of indirect exciton give the opportunity to study kinetics of magnetoexciton transport by time-resolved optical imaging of exciton emission. We present spatially and time resolved measurements showing the effect of increased magnetic field on transport of magnetoexcitons. We observe that increased magnetic field leads to slowing down of magnetoexciton transport. Supported by NSF Grant No. 1407277. J.W. was supported by the EPSRC (Grant EP/L022990/1).

Orthopaedic research and education foundation and industry.

2003-07-01

Members of orthopaedic industry commit a significant amount of funds each year to support research and education programs that are directly related to their product(s). In addition, industry supports organizations such as the Orthopaedic Research and Education Foundation. The relationship between the Orthopaedic Research and Education Foundation and industry began in the early 1980s. The support to the Orthopaedic Research and Education Foundation from industry primarily has come in the form of unrestricted grants. These grants best can be looked at as an investment rather than a contribution. This form of giving, once called corporate philanthropy is more accurately referred to as strategic philanthropy. Members of industry make these investments to enhance their reputations, build brand awareness, market their products and services, improve employee morale, increase customer loyalty, and establish strategic alliances. The specialty of orthopaedics is among the leaders in medicine in the amount of funding raised within the specialty for research and education programs. This is because of the amount of support from members of industry and the surgeons. During the past 15 years, 40% of the annual support to the Orthopaedic Research and Education Foundation has come from industry and the balance has come from surgeons and members of lay public. Future industry support of the Orthopaedic Research and Education Foundation and other organizations within the specialty of orthopaedics will be dependent on the continued demonstration of tangible returns in areas described.

Energy Production from Biogas: Competitiveness and Support Instruments in Latvia

2016-10-01

Use of renewable energy sources (RES) might be one of the key factors for the triple win-win: improving energy supply security, promoting local economic development, and reducing greenhouse gas emissions. The authors ex-post evaluate the impact of two main support instruments applied in 2010-2014 - the investment support (IS) and the feed-in tariff (FIT) - on the economic viability of small scale (up to 2MWel) biogas unit. The results indicate that the electricity production cost in biogas utility roughly corresponds to the historical FIT regarding electricity production using RES. However, if in addition to the FIT the IS is provided, the analysis shows that the practice of combining both the above-mentioned instruments is not optimal because too high total support (overcompensation) is provided for a biogas utility developer. In a long-term perspective, the latter gives wrong signals for investments in new technologies and also creates unequal competition in the RES electricity market. To provide optimal biogas utilisation, it is necessary to consider several options. Both on-site production of electricity and upgrading to biomethane for use in a low pressure gas distribution network are simulated by the cost estimation model. The authors' estimates show that upgrading for use in a gas distribution network should be particularly considered taking into account the already existing infrastructure and technologies. This option requires lower support compared to support for electricity production in small-scale biogas utilities.

Care-giving as a Canadian-Vietnamese tradition: 'it's like eating, you just do it'.

PubMed

Donovan, Rhonda; Williams, Allison M

2015-01-01

The objective of this study was to examine how Vietnamese family caregivers (FCGs) perceive, manage and experience end-of-life care-giving for seriously ill family members. Using an instrumental case study design, this longitudinal qualitative research employed the use of cultural brokers/language interpreters to help ensure that the research was conducted in a culturally-appropriate manner. Participants (n = 18) discussed their experiences of care-giving within the context of a traditional cultural framework, which was found to influence their motivations and approaches to care-giving, as well as their propensities towards the use of various supports and services. The study was carried out in southern Ontario, Canada, and participants were providing home-based care-giving in the community. Data were collected throughout 2010 and 2011. The ways in which care-giving was perceived and expressed are reflected in three themes: (i) Natural: identity and care work; (ii) Intentional: whole-person care; and (iii) Intensive: standards, struggle and the context of care. This research confirms the need for culturally-appropriate services and supports while illustrating that Vietnamese FCGs not only value, but are also likely to use healthcare and social services if they are language-accessible, built on trust and demonstrate respect for their values as individuals, regardless of culture. © 2014 The Authors.

On Nash-Equilibria of Approximation-Stable Games

NASA Astrophysics Data System (ADS)

Awasthi, Pranjal; Balcan, Maria-Florina; Blum, Avrim; Sheffet, Or; Vempala, Santosh

One reason for wanting to compute an (approximate) Nash equilibrium of a game is to predict how players will play. However, if the game has multiple equilibria that are far apart, or ɛ-equilibria that are far in variation distance from the true Nash equilibrium strategies, then this prediction may not be possible even in principle. Motivated by this consideration, in this paper we define the notion of games that are approximation stable, meaning that all ɛ-approximate equilibria are contained inside a small ball of radius Δ around a true equilibrium, and investigate a number of their properties. Many natural small games such as matching pennies and rock-paper-scissors are indeed approximation stable. We show furthermore there exist 2-player n-by-n approximation-stable games in which the Nash equilibrium and all approximate equilibria have support Ω(log n). On the other hand, we show all (ɛ,Δ) approximation-stable games must have an ɛ-equilibrium of support O(Δ^{2-o(1)}/ɛ2{log n}), yielding an immediate n^{O(Δ^{2-o(1)}/ɛ^2log n)}-time algorithm, improving over the bound of [11] for games satisfying this condition. We in addition give a polynomial-time algorithm for the case that Δ and ɛ are sufficiently close together. We also consider an inverse property, namely that all non-approximate equilibria are far from some true equilibrium, and give an efficient algorithm for games satisfying that condition.

SUNRISE: A SpaceFibre Router

2016-08-01

SpaceFibre is a new generation of SpaceWire technology which is able to support the very high data- rates required by sensors like SAR and multi-spectral imagers. Data rates of between 1 and 16 Gbits/s are required to support several sensors currently being planned. In addition a mass-memory unit requires high performance networking to interconnect many memory modules. SpaceFibre runs over both electrical and fibre-optic media and provides and adds quality of service and fault detection, isolation and recovery technology to the network. SpaceFibre is compatible with the widely used SpaceWire protocol at the network level allowing existing SpaceWire devices to be readily incorporated into a SpaceFibre network. SpaceFibre provides 2 to 5 Gbits/s links (2.5 to 6.25 Gbits/s data signalling rate) which can be operated in parallel (multi-laning) to give higher data rates. STAR- Dundee with University of Dundee has designed and tested several SpaceFibre interface devices.The SUNRISE project is a UK Space Agency, Centre for Earth Observation and Space Technology (CEOI- ST) project in which STAR-Dundee and University of Dundee will design and prototype critical SpaceFibre router technology necessary for future on-board data- handling systems. This will lay a vital foundation for future very high data-rate sensor and telecommunications systems.This paper give a brief introduction to SpaceFibre, explains the operation of a SpaceFibre network, and then describes the SUNRISE SpaceFibre Router. The initial results of the SUNRISE project are described.

Measuring Small Debris - What You Can't See Can Hurt You

2016-01-01

While modeling gives us a tool to better understand the Earth orbit debris environment, it is measurements that give us "ground truth" about what is happening in space. Assets that can detect orbital debris remotely from the surface of the Earth, such as radars and telescopes, give us a statistical view of how debris are distributed in space, how they are being created, and how they are evolving over time. In addition, in situ detectors in space are giving us a better picture of how the small particle environment is actually damaging spacecraft today. IN addition, simulation experiments on the ground help us to understand what we are seeing in orbit. This talk will summarize the history of space debris measurements, how it has changed our view of the Earth orbit environment, and how we are designing the experiments of tomorrow.

First Airborne IPDA Lidar Measurements of Methane and Carbon Dioxide Applying the DLR Greenhouse Gas Sounder CHARM-F

First airborne measurement using CHARM-F, the four-wavelengths lidar for simultaneous soundings of atmospheric CO2 and CH4, were performed in Spring 2015 onboard the German research aircraft HALO. The lidar is designed in the IPDA (integrated path differential absorption) configuration using short double pulses, which gives column averaged gas mixing ratios between aircraft and ground. HALO's maximum flight altitude of 15 km and special features of the lidar, such as a relatively large laser ground spot, enable the CHARM-F system to be an airborne demonstrator for future spaceborne greenhouse gas lidars. Due to a high technological conformity this applies in particular to the French-German satellite mission MERLIN, the spaceborne methane IPDA lidar. The successfully completed flight measurements provide a valuable dataset, which supports the retrieval algorithm development for MERLIN notably. The flights covered different ground cover types, different orography types as well as the sea. Additionally, we captured different cloud conditions, at which the broken cloud case is a matter of particular interest. This dataset allows detailed analyses of measurement sensitivities, general studies on the IPDA principle and on technical details of the system. These activities are supported by another instrument onboard: a cavity ring down spectrometer, providing in-situ data of carbon dioxide, methane and water vapor with high accuracy and precision, which is ideal for validation purposes of the lidar. Additionally the onboard instrumentation of HALO gives information about pressure and temperature for cross-checking the ECMWF data, which are intended to be used for calculating the weighting function, the key quantity for the retrieval of gas column mixing ratios from the measured gas optical depths. In combination with dedicated descents into the boundary layer and subsequent ascents, a self-contained dataset for characterizations of CHARM-F is available.

Cleavage of sp3 C-O bonds via oxidative addition of C-H bonds.

2009-11-04

(PCP)Ir (PCP = kappa(3)-C(6)H(3)-2,6-[CH(2)P(t-Bu)(2)](2)) is found to undergo oxidative addition of the methyl-oxygen bond of electron-poor methyl aryl ethers, including methoxy-3,5-bis(trifluoromethyl)benzene and methoxypentafluorobenzene, to give the corresponding aryloxide complexes (PCP)Ir(CH(3))(OAr). Although the net reaction is insertion of the Ir center into the C-O bond, density functional theory (DFT) calculations and a significant kinetic isotope effect [k(CH(3))(OAr)/k(CD(3))(OAr) = 4.3(3)] strongly argue against a simple insertion mechanism and in favor of a pathway involving C-H addition and alpha-migration of the OAr group to give a methylene complex followed by hydride-to-methylene migration to give the observed product. Ethoxy aryl ethers, including ethoxybenzene, also undergo C-O bond cleavage by (PCP)Ir, but the net reaction in this case is 1,2-elimination of ArO-H to give (PCP)Ir(H)(OAr) and ethylene. DFT calculations point to a low-barrier pathway for this reaction that proceeds through C-H addition of the ethoxy methyl group followed by beta-aryl oxide elimination and loss of ethylene. Thus, both of these distinct C-O cleavage reactions proceed via initial addition of a C(sp(3))-H bond, despite the fact that such bonds are typically considered inert and are much stronger than C-O bonds.

The cognitive interpersonal model predicts that parental caregiving style will impact on the rate of improvement of anorexia nervosa symptoms. The study aims to examine whether the absolute levels and the relative congruence between mothers' and fathers' care giving styles influenced the rate of change of their children's symptoms of anorexia nervosa over 12 months. Triads (n=54) consisting of patients with anorexia nervosa and both of their parents were included in the study. Caregivers completed the Caregiver Skills scale and the Accommodation and Enabling Scale at intake. Patients completed the Short Evaluation of Eating Disorders at intake and at monthly intervals for one year. Polynomial Hierarchical Linear Modeling was used for the analysis. There is a person/dose dependant relationship between accommodation and patients' outcome, i.e. when both mother and father are highly accommodating outcome is poor, if either is highly accommodating outcome is intermediate and if both parents are low on accommodation outcome is good. Outcome is also good if both parents or mother alone have high levels of carer skills and poor if both have low levels of skills. Including only a sub-sample of an adolescent clinical population; not considering time spent care giving, and reporting patient's self-reported outcome data limits the generalisability of the current findings. Accommodating and enabling behaviours by family members can serve to maintain eating disorder behaviours. However, skilful behaviours particularly by mothers, can aid recovery. Clinical interventions to optimise care giving skills and to reduce accommodation by both parents may be an important addition to treatment for anorexia nervosa. Copyright © 2015 Elsevier B.V.

The use of reversible covalent bonding in a four-component assembly incorporating chiral alcohols was recently reported to give a method for determining the enantiomeric excess of the alcohols via CD spectroscopy. Experiments that probe the mechanism of this assembly, which consists of 2-formylpyridine (2-PA), dipicolylamine (DPA), Zn(ii) and alcohols to yield zinc complexes of tren-like ligands, are presented. The studies focus upon the mechanism of conversion of a hemi-aminal (1) to a hemi-aminal ether (3), thereby incorporating the fourth component. It was found that molecular sieves along with 3 to 4 equivalents of alcohol are required to drive the conversion of 1 to 3. Attempts to isolate an intermediate in this reaction via addition of strong Lewis acids led to the discovery of a five-membered ring pyridinium salt (5), but upon exposure to Zn(ii) and alcohols gave different products to the assembly. This was interpreted to support the intermediacy of an iminium species. Kinetic studies reveal that the conversion of 1 to 3 is zero-order in alcohol in large excesses of alcohol, supporting rate-determining formation of an intermediate prior to reaction with alcohol. Further, the magnitudes of the rate constants for interconversion of 1 and 3 are similar, supporting the notion that there are similar rate-determining steps (rds) for the forward and reverse reactions. Hammett plots show that the rds involves creation of a negative charge (interpreted as the loss of positive charge), supporting the notion that the decomplexation of Zn(ii) from the assemblies to generate apo-forms of 1 and 3 is rate-determining. The individual mechanistic conclusions are combined to create a qualitative reaction coordinate diagram for the interconversion of 1 and 3. PMID:25530834

Regression Analysis of Top of Descent Location for Idle-thrust Descents

NASA Technical Reports Server (NTRS)

Stell, Laurel; Bronsvoort, Jesper; McDonald, Greg

2013-01-01

In this paper, multiple regression analysis is used to model the top of descent (TOD) location of user-preferred descent trajectories computed by the flight management system (FMS) on over 1000 commercial flights into Melbourne, Australia. The independent variables cruise altitude, final altitude, cruise Mach, descent speed, wind, and engine type were also recorded or computed post-operations. Both first-order and second-order models are considered, where cross-validation, hypothesis testing, and additional analysis are used to compare models. This identifies the models that should give the smallest errors if used to predict TOD location for new data in the future. A model that is linear in TOD altitude, final altitude, descent speed, and wind gives an estimated standard deviation of 3.9 nmi for TOD location given the trajec- tory parameters, which means about 80% of predictions would have error less than 5 nmi in absolute value. This accuracy is better than demonstrated by other ground automation predictions using kinetic models. Furthermore, this approach would enable online learning of the model. Additional data or further knowl- edge of algorithms is necessary to conclude definitively that no second-order terms are appropriate. Possible applications of the linear model are described, including enabling arriving aircraft to fly optimized descents computed by the FMS even in congested airspace. In particular, a model for TOD location that is linear in the independent variables would enable decision support tool human-machine interfaces for which a kinetic approach would be computationally too slow.

New solutions for personalised health management: citizens' needs, healthcare changes, and market perspectives round table debate.

The aim with the round table was to give additional inputs and views to the specific technology oriented presentations focusing on issues dealing with the need, patients' view, the use and the business opportunities relating to wearable eHealth systems for personalised health management. Wearable eHealth systems for personalised health management are targeting citizens, patients at health risks and patients enrolled in open care or home care for monitoring, treatment or follow up. The developments so far show promises for these group categories, and in addition, could support developments in health care organisations and systems. However, the ethical issues and data privacy nature have to be seriously taken into account. The market is not yet developed, and this is the situation both in Europe and in the US. To be able to give the customers solid product information a standardised test bed for new equipment and services might speed up the market development. In the round table discussion it was highlighted that one has to differ between needs and demands. Needs are related to the prevalence of the diseases, the health risks, etc. Demands are more related to market developments and customers' willingness to pay for the new products and services. Further, technical interoperability was seen as a fundamental prerequisite for market acceptance. As wearable eHealth systems for personalised health management differ completely from traditional way of deliver healthcare, new reimbursement systems have to be developed and implemented.

Managing Risk in Safety Critical Operations - Lessons Learned from Space Operations

NASA Technical Reports Server (NTRS)

Gonzalez, Steven A.

2002-01-01

The Mission Control Center (MCC) at Johnson Space Center (JSC) has a rich legacy of supporting Human Space Flight operations throughout the Apollo, Shuttle and International Space Station eras. Through the evolution of ground operations and the Mission Control Center facility, NASA has gained a wealth of experience of what it takes to manage the risk in Safety Critical Operations, especially when human life is at risk. The focus of the presentation will be on the processes (training, operational rigor, team dynamics) that enable the JSC/MCC team to be so successful. The presentation will also share the evolution of the Mission Control Center architecture and how the evolution was introduced while managing the risk to the programs supported by the team. The details of the MCC architecture (e.g., the specific software, hardware or tools used in the facility) will not be shared at the conference since it would not give any additional insight as to how risk is managed in Space Operations.

"You Get More Than You Give": Experiences of Community Partners in Facilitating Active Recreation with Individuals who have Complex Communication Needs.

Recreation is an essential part of life that provides enriching experiences that may define one's life course similar to careers or other interests. An understanding of the role of volunteers in active community-based recreational programs can help to generate ways to enhance participation and contribute to additional communication opportunities with people who have complex communication needs. Nine volunteers from two adaptive ski programs and one therapeutic horseback-riding program in the Northeast region of the United States participated in semi-structured interviews. Audio-recordings were transcribed and analyzed and resulted in five thematic areas: (a) benefits, (b) why individuals volunteer, (c) barriers, (d) successful program supports, and (e) who are the riders and skiers using AAC. The findings provided insight to support the notion that active community-based recreational activities foster an environment for communication, meaningful engagement, and social relationships between volunteers and people with complex communication needs.

Death and caring for dying patients: exploring first-year nursing students' descriptive experiences.

2014-10-01

To describe first-year nursing students' experiences of witnessing death and providing end-of-life care. This study is part of a larger longitudinal project. Interviews (n=17) were conducted with nursing students at the end of their first year of education. To analyse the interviews (lived-experience descriptions), a thematic analysis, 'a search for meaning' ( Van Manen, 1997 ) was applied. The results are presented within the framework of four separate themes: (1) The thought of death is more frightening than the actual experience, (2) Daring to approach the dying patient and offering something of oneself, (3) The experience of not sufficing in the face of death and (4) Being confronted with one's own feelings. Nursing students require continuous support and opportunity to reflect and discuss their experiences about caring for dying patients and confronting death throughout the entirety of their education. In addition, teachers and clinical supervisors need to give support using reflective practice to help students to develop confidence in their capacity for caring for dying patients.

A Verbal Guidance System for Severe Disabled People

NASA Astrophysics Data System (ADS)

Redjati, Abdelghani; Bousbia-Salah, Mounir

2008-06-01

The recent development in rehabilitation technology allows to significantly broaden the range of possible applications that support handicapped people in their daily lives. This paper presents a moral and physical support for the disabled. It consists in the development of a verbal guidance system based on a speech recognition development kit `VD364'. This aid is intended to control a wheelchair and a manipulator arm for people with severe disabilities and who can speak. The study and design, conducted in the framework of this contribution have enabled an adaptation for a possible application and maximum exploitation of words that can be generated by a vocal module. The problem addressed is to allow a manipulator arm to compensate mechanically arm movements to give the handicapped satisfaction of his needs (for instance, drinking a glass of water). The objective is then to put forward a vocal command system that allows the arm to move in a well determined area to accomplish tasks that must be given by the user in addition to the displacement of the wheelchair.

Enhancing patient freedom in rehabilitation robotics using gaze-based intention detection.

PubMed

Novak, Domen; Riener, Robert

2013-06-01

Several design strategies for rehabilitation robotics have aimed to improve patients' experiences using motivating and engaging virtual environments. This paper presents a new design strategy: enhancing patient freedom with a complex virtual environment that intelligently detects patients' intentions and supports the intended actions. A 'virtual kitchen' scenario has been developed in which many possible actions can be performed at any time, allowing patients to experiment and giving them more freedom. Remote eye tracking is used to detect the intended action and trigger appropriate support by a rehabilitation robot. This approach requires no additional equipment attached to the patient and has a calibration time of less than a minute. The system was tested on healthy subjects using the ARMin III arm rehabilitation robot. It was found to be technically feasible and usable by healthy subjects. However, the intention detection algorithm should be improved using better sensor fusion, and clinical tests with patients are needed to evaluate the system's usability and potential therapeutic benefits.

Morphological and biomechanical analysis of a skeleton from Roman imperial necropolis of Casalecchio di Reno (Bologna, Italy, II-III c. A. D.). A possible case of crutch use.

PubMed

Belcastro, M G; Mariotti, V

2000-12-01

A Roman skeleton (T.130) from the roman necropolis of Casalecchio di Reno has been studied in order to understand if the hypothesis of crutch use, suggested by the severe articular degeneration at the hip joint that caused evident reduction of his locomotory possibilities, could be supported by the morphological alterations of other bones and joints. The pathological changes and muscular development of the upper limbs and shoulder girdle bones suggest that these parts were submitted to a great mechanical stress. The observations are consistent with the hypothesis of crutch use that would have involved a new weight-bearing function of the upper limbs in order to help locomotion, even though it is difficult to assess the number and type of the crutches. The comparison with other possible cases of crutch use reported in literature gives an additional support to the interpretation of the findings.

Field and laboratory determination of a poly(vinyl/vinylidene chloride) additive in brick mortar.

PubMed

Law, S L; Newman, J H; Ptak, F L

1990-02-01

A polymerized vinyl/vinylidene chloride additive, used in brick mortar during the 60s and 70s, is detected at the building site by the field method, which employs a commercially available chloride test strip. The field test results can then be verified by the laboratory methods. In one method, total chlorine in the mortar is determined by an oxygen-bomb method and the additive chloride is determined by difference after water-soluble chlorides have been determined on a separate sample. In the second method, the polymerized additive is extracted directly from the mortar with tetrahydrofuran (THF). The difference in weight before and after extraction of the additive gives the weight of additive in the mortar. Evaporation of the THF from the extract leaves a thin film of the polymer, which gives an infrared "fingerprint" spectrum characteristic of the additive polymer.

Improving low health literacy and patient engagement: A social ecological approach.

PubMed

McCormack, Lauren; Thomas, Veronica; Lewis, Megan A; Rudd, Rima

2017-01-01

This article posits four principal objectives related to the overarching goal of broadening the conceptualization of health literacy. We propose a social ecological approach to health literacy and patient engagement by illustrating how this multilevel approach offers an array of strategic options for interventions. A social ecological approach supports a broader understanding of health literacy that aligns with increased patient engagement. The ecological model highlights the importance of context, demonstrates how health literacy and patient engagement are inextricably connected, and gives rise to strategies to enhance them both. We illustrate the five multilevel intervention strategies for addressing low health literacy and promoting patient engagement: accumulation, amplification, facilitation, cascade, and convergence strategies. In addition, we provide a theoretical foundation to facilitate the development of interventions to enhance health literacy and ultimately increase patient engagement. The practice implications of adopting a broader social ecological perspective to address low health literacy shifts the field from thinking about individual educational interventions to how individual interventions may be augmented or supported by interventions at additional levels of influence. The potential benefit of adopting a multilevel intervention approach is that combining interventions could produce synergies that are greater than interventions that only utilize one level of influence.

Plumridge, Gillian; Metcalfe, Alison; Coad, Jane; Gill, Paramjit

2011-01-01

Abstract Background  Giving children and young people information about genetic conditions and associated risk has been shown to be important to their identity, coping and decision making. Parents, however, find talking to their children difficult, and support from health professionals is often not available to them. Objective  To explore the role of support groups in family coping, and in assisting parents’ communication about risk with children in families affected by an inherited genetic condition. Methods  Semi‐structured interviews analysed using grounded theory and informed by models focusing on aspects of family communication. Participants  Affected and unaffected children and their parents, from families affected by one of six genetic conditions, that represent different patterns of inheritance, and variations in age of onset, life expectancy and impact on families. Results  Parents often sought support they did not receive elsewhere from support groups. They identified benefits, but also potential disadvantages to this involvement. These related to the specific condition and also whether groups were run solely by parents or had professional input. Support groups rarely helped directly with family communication, but attendance often stimulated family discussion, and they provided information that improved parents’ confidence in discussing the condition. Conclusions  Support groups should be seen only as additional to the support offered by health and social care professionals. An increased understanding of the role of support groups in assisting families with genetic conditions has been highlighted, but further work is needed to explore more fully how this may be made more sustainable and far‐reaching.

Effect of Electromechanical Properties in Mn-doped BaTiO3

NASA Astrophysics Data System (ADS)

Takenaka, Hiroyuki; Cohen, R. E.

Experimental studies reported that Mn doping in BaTiO3 could improve their electromechanical properties. In addition, ageing process gives rise to a significant reversible strain effect. Performing density functional theory (DFT) calculations, we find that Mn dopant with oxygen vacancy induces local electric field of 20 MV/m in 2x2x2 (39 atom) supercell. In order to understand effects of the electromechanical properties from phenomenological point of view, we optimize electric enthalpies in Landau-Devonshire model, parametrized from DFT results, under applying electric fields. We show dielectric constant and piezoelectric coefficients from the optimized polarization paths. supported by ONR, the ERC Advanced Grant ToMCaT, and the Carnegie Institution for Science.

2012-01-01

The aim of this chapter is to introduce the reader to commonly used software packages and illustrate their input requirements, analysis options, strengths, and limitations. We focus on packages that perform more than one function and include a program for quality control, linkage, and association analyses. Additional inclusion criteria were (1) programs that are free to academic users and (2) currently supported, maintained, and developed. Using those criteria, we chose to review three programs: Statistical Analysis for Genetic Epidemiology (S.A.G.E.), PLINK, and Merlin. We will describe the required input format and analysis options. We will not go into detail about every possible program in the packages, but we will give an overview of the packages requirements and capabilities.

Dedollarization in Turkey after decades of dollarization: A myth or reality?

NASA Astrophysics Data System (ADS)

Metin-Özcan, Kıvılcım; Us, Vuslat

2007-11-01

The paper analyzes dollarization in the Turkish economy given the evidence on dedollarization signals. On conducting a Vector Autoregression (VAR) model, the empirical evidence suggests that dollarization has mostly been shaped by macroeconomic imbalances as measured by exchange rate depreciation volatility, inflation volatility and expectations. Furthermore, the generalized impulse response function (IRF) analysis, in addition to the analysis of variance decomposition (VDC) gives support to the notion that dollarization seems to sustain its persistent nature, thus hysteresis still prevails. Hence, unfavorable macroeconomic conditions apparently contribute to dollarization while dollarization itself contains inertia. Furthermore, dedollarization that presumably started after 2001 has lost headway after May 2006. Thus, it seems too early to conclude that dollarization changed its route to dedollarization.

The role of the parahippocampal cortex in cognition

PubMed Central

Aminoff, Elissa M.; Kveraga, Kestutis; Bar, Moshe

2013-01-01

The parahippocampal cortex (PHC) has been associated with many cognitive processes, including visuospatial processing and episodic memory. To characterize the role of PHC in cognition a framework is required that unifies these disparate processes. An overarching account was proposed, whereby the PHC is part of a network of brain regions that processes contextual associations. Contextual associations are the principal element underlying many higher-level cognitive processes, and thus are suitable for unifying the PHC literature. Recent findings are reviewed that provide support for the contextual associations account of PHC function. In addition to reconciling a vast breadth of literature, the synthesis presented expands the implications of the proposed account and gives rise to new and general questions about context and cognition.

Keynote presentation: Looking for Zebras When There Are Only Horses (Abstract)

NASA Astrophysics Data System (ADS)

Conti, D. M.

2018-06-01

(Abstract only) How many times have each of us thought we had made a "scientific discovery" only to realize that we were the victim of our own operational, instrumentation, or processing errors? With amateur astronomers contributing more and more to pro/am collaborations, the quality and credibility of our participation is becoming even more important. This keynote presentation will review some of the common pitfalls in producing research-grade photometry results and will give examples of some "horses" that we thought were really "zebras." In addition, it will present some procedures and new techniques for obtaining higher precision photometry. These will be especially useful in helping amateur astronomers better identify false positives in support of the upcoming TESS exoplanet mission.

The tert-butyl cation on zeolite Y: A theoretical and experimental study

NASA Astrophysics Data System (ADS)

Rosenbach, Nilton, Jr.; dos Santos, Alex P. A.; Franco, Marcelo; Mota, Claudio J. A.

2010-01-01

The structure and energy of the tert-butyl cation on zeolite Y were calculated at ONIOM(MP2(FULL)/6-31G( d, p):MNDO) level. The results indicated that the tert-butyl cation is a minimum and lies between 40 and 51 kJ mol -1 above in energy to the tert-butoxide, depending on the level of calculation. Both species are stabilized through hydrogen bonding interactions with the framework oxygen atoms. Experimental data of nucleophilic substitution of tert-butylchloride and bromide over NaY impregnated with NaCl or NaBr give additional support for the formation of the tert-butyl cation as a discrete intermediate on zeolite Y, in agreement with the calculations.

Casein kinase type II were isolated by the same procedure, from rat liver, human placenta, Querin carcinoma and yeast, and characterized. The mammalian enzymes were composed of three subunits alpha, alpha' and beta, whereas yeast kinase was composed of two subunits alpha and alpha'. It was shown that the catalytic activity, substrate and phosphate donor specificity, sensitivity to heparin and spermine were the same for all the kinases tested. The results give additional support to the suggestion [1] that the beta subunit is not required for optimal activity and specificity of yeast casein kinase II. The quaternary structure of the yeast enzyme of a molecular weight of approximately 150 000 is proposed as alpha2 alpha'2.

Process and design considerations for high-efficiency solar cells

NASA Technical Reports Server (NTRS)

Rohati, A.; Rai-Choudhury, P.

1985-01-01

This paper shows that oxide surface passivation coupled with optimum multilayer anti-reflective coating can provide approx. 3% (absolute) improvement in solar cell efficiency. Use of single-layer AR coating, without passivation, gives cell efficiencies in the range of 15 to 15.5% on high-quality, 4 ohm-cm as well as 0.1 to 0.2 ohm-cm float-zone silicon. Oxide surface passivation alone raises the cell efficiency to or = 17%. An optimum double-layer AR coating on oxide-passivated cells provides an additional approx. 5 to 10% improvement over a single-layer AR-coated cell, resulting in cell efficiencies in excess of 18%. Experimentally observed improvements are supported by model calculations and an approach to or = 20% efficient cells is discussed.

Computer-aided decision support systems for endoscopy in the gastrointestinal tract: a review.

PubMed

Liedlgruber, Michael; Uhl, Andreas

2011-01-01

Today, medical endoscopy is a widely used procedure to inspect the inner cavities of the human body. The advent of endoscopic imaging techniques-allowing the acquisition of images or videos-created the possibility for the development of the whole new branch of computer-aided decision support systems. Such systems aim at helping physicians to identify possibly malignant abnormalities more accurately. At the beginning of this paper, we give a brief introduction to the history of endoscopy, followed by introducing the main types of endoscopes which emerged so far (flexible endoscope, wireless capsule endoscope, and confocal laser endomicroscope). We then give a brief introduction to computer-aided decision support systems specifically targeted at endoscopy in the gastrointestinal tract. Then we present general facts and figures concerning computer-aided decision support systems and summarize work specifically targeted at computer-aided decision support in the gastrointestinal tract. This summary is followed by a discussion of some common issues concerning the approaches reviewed and suggestions of possible ways to resolve them.

Evaluating ecological equivalence of created marshes: comparing structural indicators with stable isotope indicators of blue crab trophic support

USGS Publications Warehouse

Llewellyn, Chris; LaPeyre, Megan K.

2010-01-01

This study sought to examine ecological equivalence of created marshes of different ages using traditional structural measures of equivalence, and tested a relatively novel approach using stable isotopes as a measure of functional equivalence. We compared soil properties, vegetation, nekton communities, and δ13C and δ15N isotope values of blue crab muscle and hepatopancreas tissue and primary producers at created (5-24 years old) and paired reference marshes in SW Louisiana. Paired contrasts indicated that created and reference marshes supported equivalent plant and nekton communities, but differed in soil characteristics. Stable isotope indicators examining blue crab food web support found that the older marshes (8 years+) were characterized by comparable trophic diversity and breadth compared to their reference marshes. Interpretation of results for the youngest site was confounded by the fact that the paired reference, which represented the desired end goal of restoration, contained a greater diversity of basal resources. Stable isotope techniques may give coastal managers an additional tool to assess functional equivalency of created marshes, as measured by trophic support, but may be limited to comparisons of marshes with similar vegetative communities and basal resources, or require the development of robust standardization techniques.

Freestanding midwifery units versus obstetric units: does the effect of place of birth differ with level of social disadvantage?

PubMed Central

2012-01-01

Background Social inequity in perinatal and maternal health is a well-documented health problem even in countries with a high level of social equality. We aimed to study whether the effect of birthplace on perinatal and maternal morbidity, birth interventions and use of pain relief among low risk women intending to give birth in two freestanding midwifery units (FMU) versus two obstetric units in Denmark differed by level of social disadvantage. Methods The study was designed as a cohort study with a matched control group. It included 839 low-risk women intending to give birth in an FMU, who were prospectively and individually matched on nine selected obstetric/socio-economic factors to 839 low-risk women intending OU birth. Educational level was chosen as a proxy for social position. Analysis was by intention-to-treat. Results Women intending to give birth in an FMU had a significantly higher likelihood of uncomplicated, spontaneous birth with good outcomes for mother and infant compared to women intending to give birth in an OU. The likelihood of intact perineum, use of upright position for birth and water birth was also higher. No difference was found in perinatal morbidity or third/fourth degree tears, while birth interventions including caesarean section and epidural analgesia were significantly less frequent among women intending to give birth in an FMU. In our sample of healthy low-risk women with spontaneous onset of labour at term after an uncomplicated pregnancy, the positive results of intending to give birth in an FMU as compared to an OU were found to hold for both women with post-secondary education and the potentially vulnerable group of FMU women without post-secondary education. In all cases, women without post-secondary education intending to give birth in an FMU had comparable and, in some respects, more favourable outcomes when compared to women with the same level of education intending to give birth in an OU. In this sample of low-risk women, we found that the effect of intended place on birth outcomes did not differ with women’s level of education. Conclusion FMU care appears to offer important benefits for birthing women with no additional risk to the infant. Both for women with and without post-secondary education, intending to give birth in an FMU significantly increased the likelihood of a spontaneous, uncomplicated birth with good outcomes for mother and infant compared to women intending to give birth in an OU. All women should be provided with adequate information about different care models and supported in making an informed decision about the place of birth. PMID:22726575

Social Motivation: Costs and Benefits of Selfishness and Otherishness.

PubMed

Crocker, Jennifer; Canevello, Amy; Brown, Ashley A

2017-01-03

We examine recent evidence on the consequences of selfishness and otherishness for psychological well-being, physical health, and relationships. In the first sections, we consider recent evidence regarding the costs and benefits of giving time, money, and support to others and the costs and benefits of taking or receiving those things from others. Then, because the behaviors of giving and taking can be motivated either by selfish or otherish concerns, we next consider the costs and benefits of the motivation underlying giving and taking. We also examine why and for whom selfishness and otherishness have consequences for psychological well-being, physical health, and relationships. We focus on mechanisms identified in research, including intrapsychic mechanisms such as positive and negative affect, self-esteem and self-efficacy, a sense of meaning and purpose in life, and a sense of connectedness to or isolation from others, as well as interpersonal processes such as reciprocation of support and responsiveness.

The contributions of family care-givers at end of life: A national post-bereavement census survey of cancer carers' hours of care and expenditures.

Family members provide vital care at end of life, enabling patients to remain at home. Such informal care contributes significantly to the economy while supporting patients' preferences and government policy. However, the value of care-givers' contributions is often underestimated or overlooked in evaluations. Without information on the activities and expenditures involved in informal care-giving, it is impossible to provide an accurate assessment of carers' contribution to end-of-life care. The aim of this study was to investigate the contributions and expenditure of informal, family care-giving in end-of-life cancer care. A national census survey of English cancer carers was conducted. Survey packs were mailed to 5271 people who registered the death of a relative to cancer during 1-16 May 2015. Data were collected on decedents' health and situation, care support given, financial expenditure resulting from care, carer well-being and general background information. In all, 1504 completed surveys were returned (28.5%). Over 90% of respondents reported spending time on care-giving in the last 3 months of the decedent's life, contributing a median 69 h 30 min of care-giving each week. Those who reported details of expenditure (72.5%) spent a median £370 in the last 3 months of the decedent's life. Carers contribute a great deal of time and money for day-to-day support and care of patients. This study has yielded a unique, population-level data set of end-of-life care-giving and future analyses will provide estimates of the economic value of family care-givers' contributions.

Eye-related pathological conditions such as glaucoma, diabetic retinopathy, and age-related macular degeneration commonly lead to decreased peripheral/central field, decreased visual acuity, and increased functional disability. We sought to answer if relationships exist between measures of visual function and reported prosocial behaviors in an older adult population with eye-related diagnoses. The sample consisted of adults, aged ≥ 60 years old, at an academic hospital's eye institute. Vision ranged from normal to severe impairment. Medical charts determined the visual acuities, ocular disease, duration of disease (DD), and visual fields (VF). Measures of giving help were via validated questionnaires on giving formal support (GFS) and giving informal support; measures of help received were perceived support (PS) and informal support received (ISR). ISR had subscales: tangible support (ISR-T), emotional support (ISR-E), and composite (ISR-C). Visual acuities of the better and worse seeing eyes were converted to LogMAR values. VF information converted to a 4-point rating scale of binocular field loss severity. DD was in years. Among 96 participants (mean age 73.28; range 60-94), stepwise regression indicated a relationship of visual variables to GFS (p < 0.05; Multiple R (2) = 0.1679 with acuity-better eye, VF rating, and DD), PS (p < 0.05; Multiple R (2) = 0.2254 with acuity-better eye), ISR-C (p < 0.05; Multiple R (2) = 0.041 with acuity-better eye), and ISR-T (p < 0.05; Multiple R (2) = 0.1421 with acuity-better eye). The findings suggest eye-related conditions can impact levels and perceptions of support exchanges. Our data reinforces the importance of visual function as an influence on prosocial behavior in older adults.

Response expectancy versus response hope in predicting birth-related emotional distress and pain.

PubMed

Anton, Raluca; David, Daniel

2013-01-01

Response expectancies and response hopes have been shown to be two distinct constructs with important implications for nonvolitional outcomes. More specifically, studies show that response expectancies: (1) are sufficient to cause nonvolitional outcomes, (2) are not mediated by other psychological variables, and (3) are self-confirming while seemingly automatic. A new programmatic research line has differentiated between people's response expectancies and their response hopes regarding nonvolitional outcomes and showed that even if response hope and response expectancy are separate constructs, they are not unrelated. These concepts have not yet been studied in pregnant women. Moreover, determining the causal factors that best explain the variance of emotional distress and pain in pregnancy is of great importance. Thus, the aim of this study was to investigate the interrelations between response expectancy and response hope in pregnant women with respect to (1) emotional distress prior to giving birth and (2) pain during giving birth. Additionally, self-reported labor hours were analyzed as a secondary outcome. Results show that response expectancy for pain directly predicts pain, and that the discrepancy between response hopes and response expectancies is a strong predictor of investigated outcomes. Thus, our results support the idea that preventive psychological interventions for pregnant women should emphasize adjusting response expectancies and response hopes regarding the pain and emotional distress associated with giving birth. We believe that the results have both theoretical and practical implications and the topic deserves further investigation.

Giving Leads to Happiness in Young Children

PubMed Central

Aknin, Lara B.; Hamlin, J. Kiley; Dunn, Elizabeth W.

2012-01-01

Evolutionary models of cooperation require proximate mechanisms that sustain prosociality despite inherent costs to individuals. The “warm glow” that often follows prosocial acts could provide one such mechanism; if so, these emotional benefits may be observable very early in development. Consistent with this hypothesis, the present study finds that before the age of two, toddlers exhibit greater happiness when giving treats to others than receiving treats themselves. Further, children are happier after engaging in costly giving – forfeiting their own resources – than when giving the same treat at no cost. By documenting the emotionally rewarding properties of costly prosocial behavior among toddlers, this research provides initial support for the claim that experiencing positive emotions when giving to others is a proximate mechanism for human cooperation.

A novel compound which have one N-H fragment and nitrophenyl group has been designed and synthesized from cinnamaldehyde. The reaction was conducted in 3 step reactions to give the final product. Firstly, cinnamaldehyde was converted into cinnamic acid, which was then esterified with methyl alcohol to obtained methyl cinnamate. The last step was the addition reaction between methyl cinnamate and 2-amino-4-nitrophenol to give a cinnamaldehyde derivative, namely methyl-3-(2-hidroksi-5-nitrophenyl amino)-3- phenylpropanoate.

A short guide to giving bad news.

PubMed

Mitchell, Jeffrey T

2008-01-01

Approaching an individual or a family with bad news, but without an appropriate plan to present the information in a structured manner, is almost a guarantee of greater emotional pain and disruption for the recipients of the news. Crisis interveners must develop a strategic plan for the announcement of bad news. That plan should entail a lead-up phase, a transmission phase, and a followup phase. The lead-up phase encompasses the gathering of accurate, verifiable information and the clear identification of the targets of the information. The transmission phase includes immediate preparation for the presentation of the information, the actual announcement, and the presentation of additional details as questions arise. The follow-up phase includes a range of supportive interventions to assist people in the immediate crisis reaction. It also includes a system of referrals for people who might benefit from additional professional care. This article provides practical guidelines for providing bad news to the loved ones of injured, ill, or deceased people.

2017-09-01

Single cell microscopy in a three-dimensional (3-D) environment is reported. Cells are grown in an agarose culture gel, located within microcapillaries and observed from different sides after adaptation of an innovative device for sample rotation. Thus, z-stacks can be recorded by confocal microscopy in different directions and used for illustration in 3-D. This gives additional information, since cells or organelles that appear superimposed in one direction, may be well resolved in another one. The method is tested and validated with single cells expressing a membrane or a mitochondrially associated green fluorescent protein, or cells accumulating fluorescent quantum dots. In addition, axial tomography supports measurements of cellular uptake and distribution of the anticancer drug doxorubicin in the nucleus (2 to 6 h after incubation) or the cytoplasm (24 h). This paper discusses that upon cell rotation an enhanced optical resolution in lateral direction compared to axial direction can be utilized to obtain an improved effective 3-D resolution, which represents an important step toward super-resolution microscopy of living cells.

Tailoring decoherence in nanomagnets by geometrical design

NASA Astrophysics Data System (ADS)

Delgado, Fernando; FernáNdez-Rossier, JoaquíN.

Magnetic atoms on surfaces suffer relaxation and decoherence, which limit their possible applications in both classical storage and quantum computation. Kondo exchange interaction is usually the dominant source of relaxation. Hence, for a single magnetic impurity, the product of density of states at the Fermi level and the Kondo coupling controls relaxation and decoherence together with the renormalization of the magnetic anisotropy. Here we show that in the case of small arrays of magnetic adatoms, which can be build by STM manipulation, relaxation and decoherence are controlled in addition by the product of Fermi wavenumber and inter-spin distance, giving place to interesting interference phenomena similar to those appearing in optics. This is nothing else that the dissipative counterpart of the RKKY oscillation. In addition, we explore different configurations to reduce the spin decoherence of antiferromagnetic spin arrays opening a route to engineer spin relaxation and decoherence in atomically designed spin structures.

2005-09-01

Since 1995, the German Federal Ministry for Health and Social Security funds National Reference Centres (NRC) for the laboratory surveillance of important pathogens and syndromes. Which pathogens or syndromes are selected to be covered by a NRC depends on their epidemiological relevance, the special diagnostic tools, problems with antimicrobial resistance and necessary infection control measures. Currently, there are 15 NRC, which are appointed for a period of 3 years (currently from January 2005 through December 2007). Towards the end of their appointment all NRC are evaluated by a group of specialists. The assessment of their achievements is guided by a catalogue of tasks for the NRC. In addition to the NRC, a total of 50 laboratories are appointed which provide specialist expertise for additional pathogens in order to have a broad range of pathogens for which specialist laboratories are available. Their predominant task is to give advice and support for special diagnostic problems. Both NRC and the specialist laboratories are important parts of the network for infectious disease epidemiology.

Beaty, K. S.; Perron, G.; Kay, I.; Adam, E.

2002-05-01

DSISoft is a public domain vertical seismic profile processing software package developed at the Geological Survey of Canada. DSISoft runs under MATLAB version 5.0 and above and hence is portable between computer operating systems supported by MATLAB (i.e. Unix, Windows, Macintosh, Linux). The package includes processing modules for reading and writing various standard seismic data formats, performing data editing, sorting, filtering, and other basic processing modules. The processing sequence can be scripted allowing batch processing and easy documentation. A structured format has been developed to ensure future additions to the package are compatible with existing modules. Interactive modules have been created using MATLAB's graphical user interface builder for displaying seismic data, picking first break times, examining frequency spectra, doing f- k filtering, and plotting the trace header information. DSISoft modular design facilitates the incorporation of new processing algorithms as they are developed. This paper gives an overview of the scope of the software and serves as a guide for the addition of new modules.

Reaching the limits of reciprocity in favor exchange: The effects of generous, stingy, and matched favor giving on social status.

Ouyang, Kan; Xu, Erica; Huang, Xu; Liu, Wu; Tang, Yipeng

2018-03-08

Group members gain social status via giving favors to others, but why and when they do so remain unclear in the literature. Building on social exchange theory and social status literature, we identify three types of favor giving among group members (generous, stingy, and matched) and propose that an affective mechanism (i.e., gratitude) and a cognitive mechanism (i.e., perceived competence) underlie the relationship between favor giving and status attainment. Specifically, generous/stingy favor giving has a linear relationship with status attainment through both gratitude and perceived competence, whereas matched favor giving has a curvilinear relationship with status attainment only through perceived competence. An experimental study and a field study lend support to our propositions. Our study complements the literature by offering a complete picture of how three types of favor giving among group members shape their social status in different ways.

The Smithsonian's Youth Engagement through Science (YES!) program at the National Museum of Natural History gives young people from the Washington, D.C. area the opportunity to engage in science out of school through 16-week internships. We will present the program's successful strategies and lessons learned around recruiting and engaging young people from underserved communities, and maintaining relationships that help to support their pursuit of STEM and other career paths. The YES! program connects Smithsonian collections, experts, and training with local DC youth from communities traditionally underrepresented in science careers. YES! is now in its fifth year and has directly served 122 students; demographics of alumni are 67% female, and 51% Latino, 31% African-American, 7% Asian, 5% Caucasian and 6% other. The program immerses students in science research by giving them the opportunity to work side-by-side with scientists and staff from the Smithsonian's National Museum of Natural History, Air and Space Museum, Smithsonian Gardens, and National Zoo. In addition to working on a research project, students have college preparatory courses, are trained in science communication, and apply their skills by interacting with the public on the exhibit floor.

New Radiative Transfer Capability in the EPIC Atmospheric Model with Application to Saturn and Uranus

NASA Astrophysics Data System (ADS)

Dowling, Timothy Edward; Greathouse, T. K.; Sussman, M. G.; Chanover, N. J.

2010-10-01

We have adapted radiative transfer (RT) schemes from the gas-giant seasonal models of Greathouse et al. (EGU 2010) and Sussman et al. (AGU 2009) into the EPIC atmospheric model, and applied them to Saturn and Uranus. These additions give EPIC a hierarchy of RT options to account for solar heating via CH4 absorption from 5 microns to the UV, and radiative cooling due to thermal emission of CH4, C2H2, C2H6, and collision-induced opacity between 0 and 1600 cm-1. We have written an IDL tool to calculate radiative-equilibrium T(p) profiles for model initialization. We have ported the versatile DISORT RT model (Stamnes et al. 1988) from Fortran to C, and are incorporating it into an IDL post-processing tool to allow us to create synthetic spectra from EPIC output that accounts for thermal emission, reflected solar light, and aerosol and Rayleigh scattering. We give an update of applications to simulations of middle-atmosphere temperatures for Saturn and zonal-wind spin-up experiments for Uranus.

Large-scale neural networks and the lateralization of motivation and emotion.

PubMed

Tops, Mattie; Quirin, Markus; Boksem, Maarten A S; Koole, Sander L

2017-09-01

Several lines of research in animals and humans converge on the distinction between two basic large-scale brain networks of self-regulation, giving rise to predictive and reactive control systems (PARCS). Predictive (internally-driven) and reactive (externally-guided) control are supported by dorsal versus ventral corticolimbic systems, respectively. Based on extant empirical evidence, we demonstrate how the PARCS produce frontal laterality effects in emotion and motivation. In addition, we explain how this framework gives rise to individual differences in appraising and coping with challenges. PARCS theory integrates separate fields of research, such as research on the motivational correlates of affect, EEG frontal alpha power asymmetry and implicit affective priming effects on cardiovascular indicators of effort during cognitive task performance. Across these different paradigms, converging evidence points to a qualitative motivational division between, on the one hand, angry and happy emotions, and, on the other hand, sad and fearful emotions. PARCS suggests that those two pairs of emotions are associated with predictive and reactive control, respectively. PARCS theory may thus generate important new insights on the motivational and emotional dynamics that drive autonomic and homeostatic control processes. Copyright © 2017 Elsevier B.V.

We present results from characterizing and optimizing performance of the contoured gap coaxial plasma guns under development for the ARPA-E Accelerating Low-Cost Plasma Heating And Assembly (ALPHA) program. Plasma jet diagnostics include fast photodiodes for velocimetry and interferometry for line integrated density. Additionally we present results from spectroscopy, both time resolved high resolution spectroscopy using a novel detector and time integrated survey spectroscopy, for measurements of velocity and temperature as well as impurities. Fast imaging gives plume geometry and time integrated imaging gives overall light emission. Results from a novel long record length camera developed by HyperV will also be presented. Experimental results are compared to the desired target parameters for the plasma jets. The target values for the plasmoid are velocity of 50 km/s, mass of 3.5 mg, and length of 10 cm. The best results so far from the exploration of parameter space for gun operation are: 4 mg at >50 km/s, with a length of 10 cm. Peak axial density 34 cm downstream from the muzzle is 2 ×1016 cm-3.

NNP education in neonatal end-of-life care: a needs assessment.

PubMed

Botwinski, Carol

2010-01-01

To determine from practicing neonatal nurse practitioners (NNPs) their perceived end-of-life (EOL) care learning needs. A needs assessment-based evaluation methodology was used to answer the research questions. A neonatal EOL needs assessment survey was developed, pilot tested, and then mailed to 260 NNPs across the United States. NNPs in clinical practice regarded their education on EOL for neonates and their families as inadequate. Twenty-three percent ranked "delivery room decisions to resuscitate infants considered at edge of viability" as the item for which they most wanted more training. The other top-ranked EOL items included balance between giving parents false hopes and removing all hopes, and communicating and giving bad news to families. Based on these findings, specific neonatal EOL education and communication skill workshops are warranted for graduate nursing core and advance practice continuing education courses. Additionally, there needs to be a mechanism to provide EOL content and support for the NNP already in clinical practice; it is suggested that learning about EOL issues can be integrated into existing (continuing nursing education CNE) educational activities. Further research is needed on what issues, tools, and methods in CNE programs make a difference in the experience of NNPs.

In times of fiscal and political uncertainty, philanthropy has become an increasingly important mechanism for building, maintaining, and expanding neurosurgical research programs. Although philanthropy has historically helped launch many hospital systems, scientists and clinicians have generally relied on government grants and industry investment to support research and program infrastructure. However, competition for funds from all sources has increased at the same time as the pipelines for those funds have eroded. Philanthropy can provide salary support to allow neurosurgeons to pursue research and, ultimately, advance the field to improve outcomes for patients. Funds raised can fill financial gaps to recruit and pay for needed research staff, equipment, and facilities. To foster charitable giving, institutions can develop both a culture and processes to promote and support philanthropy. Furthermore, it is essential to ensure that donor relationships are properly nurtured with ongoing stewardship. In addition to cultivating grateful patients, there are numerous creative models of fundraising for research that can be explored, including venture philanthropy, in which voluntary health organizations or individuals partner with academia and industry to invest in early-stage drug development and other innovations. Other approaches include formation of nonprofit foundations and partnerships with other entities to work jointly on shared development goals.

Pressure ulcer prevention: the role of the multidisciplinary team.

PubMed

Samuriwo, Ray

Pressure ulcer prevention has long been a priority for health professionals; however, poor pressure-ulcer-related practices like poor documentation continue to be identified. Research has shown that the attitude and behaviour of some nurses towards pressure ulcer prevention are not conducive to the best possible patient outcomes.This article reviews the findings of a Straussian grounded theory study, which sought to ascertain the value that is placed on pressure ulcer prevention by nurses, but also revealed the role that other health professionals in the multidisciplinary team play in the maintenance of skin integrity. The findings of this study which are presented in this paper highlight a number of important issues. Firstly, nurses are expected to know how to prevent and manage pressure ulcers, but in reality they are very reliant on the advice and support of other health professionals to maintain their patients' skin integrity. In addition,the level of support that nurses get from other health professionals in the multidisciplinary varies tremendously. Therefore, nurses in clinical practice need to be proactive in seeking input from other health professionals, as there are many members of the multidisciplinary team who are able to give them the advice and support that they need in prevention and management.

Implementation and assessment of a likelihood ratio approach for the evaluation of LA-ICP-MS evidence in forensic glass analysis.

PubMed

van Es, Andrew; Wiarda, Wim; Hordijk, Maarten; Alberink, Ivo; Vergeer, Peter

2017-05-01

For the comparative analysis of glass fragments, a method using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) is in use at the NFI, giving measurements of the concentration of 18 elements. An important question is how to evaluate the results as evidence that a glass sample originates from a known glass source or from an arbitrary different glass source. One approach is the use of matching criteria e.g. based on a t-test or overlap of confidence intervals. An important drawback of this method is the fact that the rarity of the glass composition is not taken into account. A similar match can have widely different evidential values. In addition the use of fixed matching criteria can give rise to a "fall off the cliff" effect. Small differences may result in a match or a non-match. In this work a likelihood ratio system is presented, largely based on the two-level model as proposed by Aitken and Lucy [1], and Aitken, Zadora and Lucy [2]. Results show that the output from the two-level model gives good discrimination between same and different source hypotheses, but a post-hoc calibration step is necessary to improve the accuracy of the likelihood ratios. Subsequently, the robustness and performance of the LR system are studied. Results indicate that the output of the LR system is robust to the sample properties of the dataset used for calibration. Furthermore, the empirical upper and lower bound method [3], designed to deal with extrapolation errors in the density models, results in minimum and maximum values of the LR outputted by the system of 3.1×10 -3 and 3.4×10 4 . Calibration of the system, as measured by empirical cross-entropy, shows good behavior over the complete prior range. Rates of misleading evidence are small: for same-source comparisons, 0.3% of LRs support a different-source hypothesis; for different-source comparisons, 0.2% supports a same-source hypothesis. The authors use the LR system in reporting of glass cases to support expert opinion in the interpretation of glass evidence for origin of source questions.

Weeks, John; Anderson, Belinda; Meeker, William; Calabrese, Carlo; O'Bryon, David; Cramer, Greg D.

2015-01-01

Abstract Background: This commentary presents the most impactful, shared priorities for research investment across the licensed complementary and integrative health (CIH) disciplines according to the Academic Consortium for Complementary and Alternative Health Care (ACCAHC). These are (1) research on whole disciplines; (2) costs; and (3) building capacity within the disciplines' universities, colleges, and programs. The issue of research capacity is emphasized. Discussion: ACCAHC urges expansion of investment in the development of researchers who are graduates of CIH programs, particularly those with a continued association with accredited CIH schools. To increase capacity of CIH discipline researchers, we recommend National Center for Complementary and Integrative Health (NCCIH) to (1) continue and expand R25 grants for education in evidence-based healthcare and evidence-informed practice at CIH schools; (2) work to limit researcher attrition from CIH institutions by supporting career development grants for clinicians from licensed CIH fields who are affiliated with and dedicated to continuing to work in accredited CIH schools; (3) fund additional stand-alone grants to CIH institutions that already have a strong research foundation, and collaborate with appropriate National Institutes of Health (NIH) institutes and centers to create infrastructure in these institutions; (4) stimulate higher percentages of grants to conventional centers to require or strongly encourage partnership with CIH institutions or CIH researchers based at CIH institutions, or give priority to those that do; (5) fund research conferences, workshops, and symposia developed through accredited CIH schools, including those that explore best methods for studying the impact of whole disciplines; and (6) following the present NIH policy of giving priority to new researchers, we urge NCCIH to give a marginal benefit to grant applications from CIH clinician-researchers at CIH academic/research institutions, to acknowledge that CIH concepts require specialized expertise to translate to conventional perspectives. Summary: We commend NCCIH for its previous efforts to support high-quality research in the CIH disciplines. As NCCIH develops its 2016–2020 strategic plan, these recommendations to prioritize research based on whole disciplines, encourage collection of outcome data related to costs, and further support capacity-building within CIH institutions remain relevant and are a strategic use of funds that can benefit the nation's health.

What influences birth place preferences, choices and decision-making amongst healthy women with straightforward pregnancies in the UK? A qualitative evidence synthesis using a 'best fit' framework approach.

English maternity care policy has supported offering women choice of birth setting for over twenty years, but only 13% of women in England currently give birth in settings other than obstetric units (OUs). It is unclear why uptake of non-OU settings for birth remains relatively low. This paper presents a synthesis of qualitative evidence which explores influences on women's experiences of birth place choice, preference and decision-making from the perspectives of women using maternity services. Qualitative evidence synthesis of UK research published January 1992-March 2015, using a 'best-fit' framework approach. Searches were run in seven electronic data bases applying a comprehensive search strategy. Thematic framework analysis was used to synthesise extracted data from included studies. Twenty-four papers drawing on twenty studies met the inclusion criteria. The synthesis identified support for the key framework themes. Women's experiences of choosing or deciding where to give birth were influenced by whether they received information about available options and about the right to choose, women's preferences for different services and their attributes, previous birth experiences, views of family, friends and health care professionals and women's beliefs about risk and safety. The synthesis additionally identified that women's access to choice of place of birth during the antenatal period varied. Planning to give birth in OU was straightforward, but although women considering birth in a setting other than hospital OU were sometimes well-supported, they also encountered obstacles and described needing to 'counter the negativity' surrounding home birth or birth in midwife-led settings. Over the period covered by the review, it was straightforward for low risk women to opt for hospital birth in the UK. Accessing home birth was more complex and contested. The evidence on freestanding midwifery units (FMUs) is more limited, but suggests that women wanting to opt for an FMU birth experienced similar barriers. The extent to which women experienced similar problems accessing alongside midwifery units (AMUs) is unclear. Women's preferences for different birth options, particularly for 'hospital' vs non-hospital settings, are shaped by their pre-existing values, beliefs and experience, and not all women are open to all birth settings.

For many years, family blood donors have been considered less safe than volunteer non-remunerated blood donors and actively discouraged by international organisations and affluent countries support agencies for developing countries. In addition to safety, pressure and coercion was considered unethical. However these assumptions were not supported by evidence. To assemble recently collected evidence to reopen the assessment whether or not the ban of family blood donors is justified. Review of old and recent literature through Pubmed and references from identified articles. Viral marker data comparing confirmed seroprevalence in 1(st) time volunteer non-remunerated donors (VNRD) and family/replacement donors (FRD) corrected for gender and age, show no significant difference between the two groups. Evidence has been provided that for both VNRD and FAD benevolence is more appropriate than altruism. The two groups merge for psychological attitude to donation for which knowing someone needing transfusion is a powerful incentive to give blood. Excluding a life or death situation found in areas where severe blood shortage justifies replacement donation, pressures are exerted on both VNRD and FRD. There is no evidence of coercion of FRD. FRDs therefore meet all criteria for VNRD and are willing to become VNRD and to repeat donation. Ostracising FRD is illegitimate and damaging to the blood supply in resource poor areas. In some countries no difference is made between the two groups of donors representing similar populations asked to give blood in different circumstances. FRDs remain a critical source of volunteer, non-remunerated, blood meeting all classical criteria of VNRD that should be considered legitimate and indispensable at this point in time instead of discouraged.

Providing informal caregiving in the acute in-patient and post-hospital discharge phases places enormous burden on the caregivers who often require some form of social support. However, it appears there are few published studies about informal caregiving in the acute in-patient phase of individuals with stroke particularly in poor-resource countries. This study was designed to evaluate the prevalence of caregiving burden and its association with patient and caregiver-related variables and also level of perceived social support in a sample of informal caregivers of stroke survivors at an acute stroke-care facility in Nigeria. Ethical approval was sought and obtained. Fifty-six (21 males, 35 females) consecutively recruited informal caregivers of stroke survivors at the medical ward of a tertiary health facility in South-Southern Nigeria participated in this cross-sectional survey. Participants' level of care-giving strain/burden and perceived social support were assessed using the Caregiver Strain Index and the Multidimensional Scale of Perceived Social Support respectively. Caregivers' and stroke survivors' socio-demographics were also obtained. Data was analysed using frequency count and percentages, independent t-test, analysis of variance (ANOVA) and partial correlation at α =0.05. The prevalence of care-giving burden among caregivers is 96.7% with a high level of strain while 17.9% perceived social support as low. No significant association was found between caregiver burden and any of the caregiver- or survivor-related socio-demographics aside primary level education. Only the family domain of the Multidimensional Scale of Perceived Social Support was significantly correlated with burden (r = - 0.295). Informal care-giving burden was highly prevalent in this acute stroke caregiver sample and about one in every five of these caregivers rated social support low. This is a single center study. Healthcare managers and professionals in acute care facilities should device strategies to minimize caregiver burden and these may include family education and involvement.

Novel brain-penetrating oximes for reactivation of cholinesterase inhibited by sarin and VX surrogates

PubMed Central

Chambers, Janice E.; Meek, Edward C.; Chambers, Howard W.

2016-01-01

Current oxime reactivators for organophosphate-inhibited cholinesterase (ChE) do not effectively cross the blood–brain barrier and therefore cannot restore brain ChE activity in vivo. Our laboratories have studied highly relevant sarin and VX surrogates, which differ from their respective nerve agents only in the leaving group and thereby leave ChE phosphylated with the same chemical moiety as sarin and VX. Our laboratories have invented novel substituted phenoxyalkyl pyridinium oximes (U.S. Patent 9,227,937 B2) that lead to reduced ChE inhibition in the brains of rats challenged with a high sublethal dosage of the sarin surrogate, whereas 2-PAM did not, using a paradigm designed to demonstrate brain penetration. In addition, these novel oximes also showed an attenuation of seizure-like behavior compared to rats treated with 2-PAM, giving additional evidence of the ability of these oximes to penetrate the blood–brain barrier. Further, some of these oximes provided 24-hour survival superior to 2-PAM and shortened the duration of seizure-like behavior when rats were challenged with lethal dosages of the sarin and VX surrogates, providing additional support for the concept of these life-saving oximes penetrating the brain.

LiDAR is a consolidated technology for topographic mapping and 3D reconstruction, which is implemented in several platforms On the other hand, the exploitation of the geometric information has been coupled by the use of laser intensity, which may provide additional data for multiple purposes. This option has been emphasized by the availability of sensors working on different wavelength, thus able to provide additional information for classification of surfaces and objects. Several applications ofmonochromatic and multi-spectral LiDAR data have been already developed in different fields: geosciences, agriculture, forestry, building and cultural heritage. The use of intensity data to extract measures of point cloud quality has been also developed. The paper would like to give an overview on the state-of-the-art of these techniques, and to present the modern technologies for the acquisition of multispectral LiDAR data. In addition, the ISPRS WG III/5 on `Information Extraction from LiDAR Intensity Data' has collected and made available a few open data sets to support scholars to do research on this field. This service is presented and data sets delivered so far as are described.

2008-10-01

We study the asymptotic behavior of the zeros of a sequence of polynomials whose weighted norms, with respect to a sequence of weight functions, have the same nth root asymptotic behavior as the weighted norms of certain extremal polynomials. This result is applied to obtain the (contracted) weak zero distribution for orthogonal polynomials with respect to a Sobolev inner product with exponential weights of the form e-[phi](x), giving a unified treatment for the so-called Freud (i.e., when [phi] has polynomial growth at infinity) and Erdös (when [phi] grows faster than any polynomial at infinity) cases. In addition, we provide a new proof for the bound of the distance of the zeros to the convex hull of the support for these Sobolev orthogonal polynomials.

How to obtain traceability on optical radiation measurements?

NASA Astrophysics Data System (ADS)

Matamoros García, Carlos H.

2006-02-01

Traceability to national standards provides confidence in measurements results, granting a guaranty when carrying out governmental rules and when demonstrating conformity with quality requirements such as ISO 9000 or ISO/IEC 17025 (and the Mexican equivalent standards). The appropriate traceability contributes with confidence of the quality of products or services. This paper presents different ways to obtain traceability in Mexico for the optical radiation measurements, mentioning some applications, and highlighting the necessity of having traceability to the appropriate units of the SI. Additionally it present the national standards maintained by Centro Nacional de Metrologia (CENAM), the national metrology institute in Mexico, that give the technical support to Mexican measurements in this field and the international recognition that the personal of the Optics and Radiometry Division had gained in 10 years of development.

From dipolar to multipolar interactions between ultracold Feshbach molecules

Quéméner, Goulven; Lepers, Maxence; Luc-Koenig, Eliane; Dulieu, Olivier

2016-05-01

Using the multipolar expansion of electrostatic and magnetostatic potential energies, we characterize the long-range interactions between two weakly-bound diatomic molecules, taking as an example the paramagnetic Er2 Feshbach molecules which were produced recently. The interaction between atomic magnetic dipoles gives rise to the usual R-3 leading term of the multipolar expansion, where R is the intermolecular distance. We show that additional terms scaling as R-5, R-7 and so on also appear, which are strongly anisotropic with respect to the orientation of the molecules. These terms can be seen as effective molecular multipole moments reflecting the spatial extension of the molecules which is non-negligible compared to R.

Are psychogenic non-epileptic seizures just another symptom of conversion disorder?

2017-05-01

Psychogenic non-epileptic seizures (PNES) are classified with other functional neurological symptoms as 'Conversion Disorder', but there are reasons to wonder whether this symptomatology constitutes a distinct entity. We reviewed the literature comparing PNES with other functional neurological symptoms. We find eight studies that directly examined this question. Though all but one found significant differences-notably in presenting age, trauma history, and dissociation-they were divided on whether these differences represented an important distinction. We argue that the aetiological and mechanistic distinctions they support, particularly when bolstered by additional data, give reason to sustain a separation between these conditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Tone and prosodic organization in Cherokee nouns

NASA Astrophysics Data System (ADS)

Johnson, Keith; Haag, Marcia

2005-04-01

Preliminary observations in the speech of one speaker of Cherokee led us to postulate three factors affecting tone in Cherokee. (1) Tone may be lexically specified with distinctive low, low fall, low rise, and high tones. (2) There is a metrically determined high fall pattern which may be distributed over not more than 2 syllables from the right edge of a prosodic domain. (3) Intonational domains may be associated with discourse functions, marked by high fall, or by pitch range upstep. This paper tests these observations in recordings of word lists and sentences produced by five additional speakers. The analysis we give, positing both lexical tone and metrical prosodic accent, is not unique in descriptions of language, but is different from the usual description of Cherokee.

Species Determination and Quantitation in Mixtures Using MRM Mass Spectrometry of Peptides Applied to Meat Authentication

2016-01-01

We describe a simple protocol for identifying and quantifying the two components in binary mixtures of species possessing one or more similar proteins. Central to the method is the identification of 'corresponding proteins' in the species of interest, in other words proteins that are nominally the same but possess species-specific sequence differences. When subject to proteolysis, corresponding proteins will give rise to some peptides which are likewise similar but with species-specific variants. These are 'corresponding peptides'. Species-specific peptides can be used as markers for species determination, while pairs of corresponding peptides permit relative quantitation of two species in a mixture. The peptides are detected using multiple reaction monitoring (MRM) mass spectrometry, a highly specific technique that enables peptide-based species determination even in complex systems. In addition, the ratio of MRM peak areas deriving from corresponding peptides supports relative quantitation. Since corresponding proteins and peptides will, in the main, behave similarly in both processing and in experimental extraction and sample preparation, the relative quantitation should remain comparatively robust. In addition, this approach does not need the standards and calibrations required by absolute quantitation methods. The protocol is described in the context of red meats, which have convenient corresponding proteins in the form of their respective myoglobins. This application is relevant to food fraud detection: the method can detect 1% weight for weight of horse meat in beef. The corresponding protein, corresponding peptide (CPCP) relative quantitation using MRM peak area ratios gives good estimates of the weight for weight composition of a horse plus beef mixture.

The Launch Systems Operations Cost Model

NASA Technical Reports Server (NTRS)

Prince, Frank A.; Hamaker, Joseph W. (Technical Monitor)

2001-01-01

One of NASA's primary missions is to reduce the cost of access to space while simultaneously increasing safety. A key component, and one of the least understood, is the recurring operations and support cost for reusable launch systems. In order to predict these costs, NASA, under the leadership of the Independent Program Assessment Office (IPAO), has commissioned the development of a Launch Systems Operations Cost Model (LSOCM). LSOCM is a tool to predict the operations & support (O&S) cost of new and modified reusable (and partially reusable) launch systems. The requirements are to predict the non-recurring cost for the ground infrastructure and the recurring cost of maintaining that infrastructure, performing vehicle logistics, and performing the O&S actions to return the vehicle to flight. In addition, the model must estimate the time required to cycle the vehicle through all of the ground processing activities. The current version of LSOCM is an amalgamation of existing tools, leveraging our understanding of shuttle operations cost with a means of predicting how the maintenance burden will change as the vehicle becomes more aircraft like. The use of the Conceptual Operations Manpower Estimating Tool/Operations Cost Model (COMET/OCM) provides a solid point of departure based on shuttle and expendable launch vehicle (ELV) experience. The incorporation of the Reliability and Maintainability Analysis Tool (RMAT) as expressed by a set of response surface model equations gives a method for estimating how changing launch system characteristics affects cost and cycle time as compared to today's shuttle system. Plans are being made to improve the model. The development team will be spending the next few months devising a structured methodology that will enable verified and validated algorithms to give accurate cost estimates. To assist in this endeavor the LSOCM team is part of an Agency wide effort to combine resources with other cost and operations professionals to support models, databases, and operations assessments.

Oral health promotion by the oral health products industry: unrecognised and unappreciated?

PubMed

Barnett, M L

2008-03-01

There is often ambivalence in the way dentists view the oral health care industry. On the one hand, there are the skeptics who view corporate activities as suspect, calling into question the validity of industry-sponsored research and considering all promotional activities as self-serving. On the other hand, there are those who will evaluate research, whether industry sponsored or not, on its merits and appreciate corporate philanthropy that aims to give something back to the profession, although at times the expectations of the amount of financial support available are markedly in excess of the actual amount based on dental product sales. (Yes--and don't let your young children see this!--the tooth fairy who goes around dispensing endless number of dollars or pounds or euros does not actually exist!) Recognizing that, of necessity, corporations exist to make a profit, I would submit that the relationship of responsible companies to the profession can often be looked at as a partnership in which both sides benefit. Ultimately, all have as a goal the improvement of the oral health of our patients (or consumers) which is facilitated by the availability of effective products. In addition to marketing products, the oral care industry plays a large, though oftentimes unnoticed, role in oral health promotion. For the most part, this involves targeted financial support or contributions of products that serve to enhance patients' understanding of oral diseases and the need for good oral care, and/or provide access to care for underserved groups. In the following sections, I will give some examples of industry-supported health promotion activities, most of which will be activities in the United States with which I am most familiar. These are examples only--the list is not intended to be exhaustive and a company's name will be included in only the few instances in which it is an integral part of the programme title.

2015-01-01

Background The West African Ebola epidemic has demonstrated that the existing range of medical and epidemiological responses to emerging disease outbreaks is insufficient, especially in post-conflict contexts with exceedingly poor healthcare infrastructures. In this context, community-based responses have proven vital for containing Ebola virus disease (EVD) and shifting the epidemic curve. Despite a surge in interest in local innovations that effectively contained the epidemic, the mechanisms for community-based response remain unclear. This study provides baseline information on community-based epidemic control priorities and identifies innovative local strategies for containing EVD in Liberia. Methodology/Principal Findings This study was conducted in September 2014 in 15 communities in Monrovia and Montserrado County, Liberia – one of the epicenters of the Ebola outbreak. Findings from 15 focus group discussions with 386 community leaders identified strategies being undertaken and recommendations for what a community-based response to Ebola should look like under then-existing conditions. Data were collected on the following topics: prevention, surveillance, care-giving, community-based treatment and support, networks and hotlines, response teams, Ebola treatment units (ETUs) and hospitals, the management of corpses, quarantine and isolation, orphans, memorialization, and the need for community-based training and education. Findings have been presented as community-based strategies and recommendations for (1) prevention, (2) treatment and response, and (3) community sequelae and recovery. Several models for community-based management of the current Ebola outbreak were proposed. Additional findings indicate positive attitudes towards early Ebola survivors, and the need for community-based psychosocial support. Conclusions/Significance Local communities’ strategies and recommendations give insight into how urban Liberian communities contained the EVD outbreak while navigating the systemic failures of the initial state and international response. Communities in urban Liberia adapted to the epidemic using multiple coping strategies. In the absence of health, infrastructural and material supports, local people engaged in self-reliance in order to contain the epidemic at the micro-social level. These innovations were regarded as necessary, but as less desirable than a well-supported health-systems based response; and were seen as involving considerable individual, social, and public health costs, including heightened vulnerability to infection.

Creating a Regional Healthcare Network: People First.

Michel-Verkerke, Margreet B

2016-01-01

Care organizations in the Dutch region Apeldoorn want to collaborate more in order to improve the care provision to elderly and psychiatric patients living independently. In order to support the collaboration they intend to create a regional digital healthcare network. The research was focused on the relevance of a regional healthcare network for care providers. Eleven semi-structured interviews based on the USE IT-model, were conducted with care providers and staff members. Results show that care providers need to tune their activities for this target group and create an agreement on integrated care. The relevance of a digital communication and collaboration platform is high. The regional healthcare network should support the collaboration between care providers by: 1. Offering a communication platform to replace the time consuming communication by telephone; 2. Making patient information available for patient and care provider at patients' homes; 3. Giving insight in who is giving what care to whom; and 4. Giving access to knowledge about the target group: elderly and psychiatric patients living independently.

Population genomics of the inbred Scandinavian wolf.

2009-04-01

The Scandinavian wolf population represents one of the genetically most well-characterized examples of a severely bottlenecked natural population (with only two founders), and of how the addition of new genetic material (one immigrant) can at least temporarily provide a 'genetic rescue'. However, inbreeding depression has been observed in this population and in the absence of additional immigrants, its long-term viability is questioned. To study the effects of inbreeding and selection on genomic diversity, we performed a genomic scan with approximately 250 microsatellite markers distributed across all autosomes and the X chromosome. We found linkage disequilibrium (LD) that extended up to distances of 50 Mb, exceeding that of most outbreeding species studied thus far. LD was particularly pronounced on the X chromosome. Overall levels of observed genomic heterozygosity did not deviate significantly from simulations based on known population history, giving no support for a general selection for heterozygotes. However, we found evidence supporting balancing selection at a number of loci and also evidence suggesting directional selection at other loci. For markers on chromosome 23, the signal of selection was particularly strong, indicating that purifying selection against deleterious alleles may have occurred even in this very small population. These data suggest that population genomics allows the exploration of the effects of neutral and non-neutral evolution on a finer scale than what has previously been possible.

XML at the ADC: Steps to a Next Generation Data Archive

The eXtensible Markup Language (XML) is a document markup language that allows users to specify their own tags, to create hierarchical structures to qualify their data, and to support automatic checking of documents for structural validity. It is being intensively supported by nearly every major corporate software developer. Under the funds of a NASA AISRP proposal, the Astronomical Data Center (ADC, http://adc.gsfc.nasa.gov) is developing an infrastructure for importation, enhancement, and distribution of data and metadata using XML as the document markup language. We discuss the preliminary Document Type Definition (DTD, at http://adc.gsfc.nasa.gov/xml) which specifies the elements and their attributes in our metadata documents. This attempts to define both the metadata of an astronomical catalog and the `header' information of an astronomical table.

2000-01-01

This paper deals with the support of virtual reality computer action in the procedures of surgical robotics. Computer support gives a direct representation of the surgical theatre. The modelization of the procedure in course and in development gives a psychological reaction towards safety and reliability. Robots similar to the ones used by the manufacturing industry can be used with little modification as very effective surgical tools. They have high precision, repeatability and are versatile in integrating with the medical instrumentation. Now integrated surgical rooms, with computer and robot-assisted intervention, are operating. The computer is the element for a decision taking aid, and the robot works as a very effective tool.

A method for assessing fidelity of delivery of telephone behavioral support for smoking cessation.

2014-06-01

Behavioral support for smoking cessation is delivered through different modalities, often guided by treatment manuals. Recently developed methods for assessing fidelity of delivery have shown that face-to-face behavioral support is often not delivered as specified in the service treatment manual. This study aimed to extend this method to evaluate fidelity of telephone-delivered behavioral support. A treatment manual and transcripts of 75 audio-recorded behavioral support sessions were obtained from the United Kingdom's national Quitline service and coded into component behavior change techniques (BCTs) using a taxonomy of 45 smoking cessation BCTs. Interrater reliability was assessed using percentage agreement. Fidelity was assessed by comparing the number of BCTs identified in the manual with those delivered in telephone sessions by 4 counselors. Fidelity was assessed according to session type, duration, counselor, and BCT. Differences between self-reported and actual BCT use were examined. Average coding reliability was high (81%). On average, 41.8% of manual-specified BCTs were delivered per session (SD = 16.2), with fidelity varying by counselor from 32% to 49%. Fidelity was highest in pre-quit sessions (46%) and for BCT "give options for additional support" (95%). Fidelity was lowest for quit-day sessions (35%) and BCT "set graded tasks" (0%). Session duration was positively correlated with fidelity (r = .585; p < .01). Significantly fewer BCTs were used than were reported as being used, t(15) = -5.52, p < .001. The content of telephone-delivered behavioral support can be reliably coded in terms of BCTs. This can be used to assess fidelity to treatment manuals and to in turn identify training needs. The observed low fidelity underlines the need to establish routine procedures for monitoring delivery of behavioral support. PsycINFO Database Record (c) 2014 APA, all rights reserved.

The purpose of this study was to examine HRQOL depending on whether the participants have family members with disabilities or not. In addition, we examined the relationship between HRQOL and social networks among family caregivers in Japan. The study has a cross-sectional design. Survey forms were distributed to 9205 people aged 30 and older who visited a dispensing pharmacy within fifteen areas of Japan. We collected data on gender, age, job status, and care giving status for persons with disabilities. Moreover, we assessed support size, social support, and HRQOL. Out of the 2029 questionnaires returned, 1763 (male: 663, female: 1100, mean age = 63.06 +/- 13.34) were valid for statistical analyses (the available response rate was 19.15%). A significant difference in HRQOL was identified between family caregivers and non-family caregivers. Further, in males (N = 101), the results confirmed that only social support predicted the PCS and MCS scores, while other variables did not predict either score. On the other hand, in females (N = 144), it was found from the second step of hierarchical multiple regression analysis that only age explained the PCS score, while job status and support size explained the MCS score. It is reasonable to conclude that the HRQOL of family caregivers was lower than that of non-family caregivers, and that the HRQOL of family caregivers was estimated by their social networks.

From Healing the Whole Person: An Argument for Therapeutic Touch as a Complement to Traditional Medical Practice

PubMed Central

Huff, Marlene B.; McClanahan, Kimberly K.; Omar, Hatim A.

2006-01-01

The growing popularity and use of therapeutic touch (TT) is an issue that has generated controversy and concern within the medical community. While anecdotal and traditional scientific evidence suggest that TT would be an advantageous addition for clinics and hospitals to include in their armamentarium of complementary interventions within the realm of traditional medicine, TT has not become widely available in the U.S. One reason for the lack of availability may be the dearth of conclusive scientific support for TT's efficacy and, therefore, its inclusion in clinic and hospital treatment planning would give it the appearance of legitimate practice, which it may not yet deserve. Whether or not deserved, if TT were added to hospital and clinic treatment protocols without substantial scientific support, it would be thought to have the implicit support of the scientific community, at which point the question of its efficacy would be moot in the minds of many people; thus patients would utilize it, because they believe it works rather than because it works. Since TT has not yet been scientifically proven as per Western standards, leaders of the health care community are likely wary of lending support to TT at this time. If TT can be found to be a scientifically sound therapeutic technique, then it will be more readily accepted in the health care community. This paper reviews TT. PMID:17370014

A student-centred feedback model for educators.

PubMed

Rudland, Joy; Wilkinson, Tim; Wearn, Andy; Nicol, Pam; Tunny, Terry; Owen, Cathy; O'Keefe, Maree

2013-04-01

Effective feedback is instrumental to effective learning. Current feedback models tend to be educator driven rather than learner-centred, with the focus on how the supervisor should give feedback rather than on the role of the learner in requesting and responding to feedback. An alternative approach emphasising the theoretical principles of student-centred and self-regulated learning is offered, drawing upon the literature and also upon the experience of the authors. The proposed feedback model places the student in the centre of the feedback process, and stresses that the attainment of student learning outcomes is influenced by the students themselves. This model emphasises the attributes of the student, particularly responsiveness, receptiveness and reflection, whilst acknowledging the important role that the context and attributes of the supervisor have in influencing the quality of feedback. Educational institutions should consider strategies to encourage and enable students to maximise the many feedback opportunities available to them. As a minimum, educators should remind students about their central role in the feedback process, and support them to develop confidence in meeting this role. In addition, supervisors may need support to develop the skills to shift the balance of responsibility and support students in precipitating feedback moments. Research is also required to validate the proposed model and to determine how to support students to adopt self-regulatory learning, with feedback as a central platform. © Blackwell Publishing Ltd 2013.

The Role of Unconditional Parental Regard in Autonomy-Supportive Parenting.

Roth, Guy; Kanat-Maymon, Yaniv; Assor, Avi

2016-12-01

Two studies explored the role of parents' unconditional positive regard (UCPR) as perceived by adolescents and young adults in promoting the effectiveness of specific parenting practices that may support offspring's academic autonomous motivation. Study 1 tested the hypothesis that UCPR predicts rationale-giving and choice-provision practices and, at the same time, moderates their relations with adolescents' autonomous motivation. Study 2 replicated the association between UCPR and the parental practices, and further explored the role of parents' authenticity as an antecedent of UCPR and parental autonomy support. Study 1 included 125 adolescents and Study 2 considered 128 college-students and their mothers. The offspring reported on their perceptions of their mothers and on their autonomous motivation, and the mothers reported on their sense of authenticity. Both studies found consistent associations between UCPR and parenting practices that may support autonomous motivation. Moreover, Study 1 demonstrated that the rationale giving and choice provision were more strongly related to adolescents' autonomous motivation when adolescents perceived mothers as high on UCPR. Finally, Study 2 demonstrated that mothers' authenticity predicted UCPR, which in turn was related to autonomy-supportive parenting. Findings support the assumption that parents' autonomy-supportive practices are more effective when accompanied by UCPR. © 2015 Wiley Periodicals, Inc.

Altruism relates to health in an ethnically diverse sample of older adults.

PubMed

Brown, William Michael; Consedine, Nathan S; Magai, Carol

2005-05-01

The existing literature indicates links between aspects of social network functioning and health outcomes. It is generally believed that networks that are larger or provide greater instrumental and emotional support contribute to improved health and, perhaps, greater longevity. Recently, it has been suggested that giving as well as receiving social support may be of benefit. On the basis of evolutionary theories of emotion and altruism, the current study sought to test this thesis in a large, ethnically diverse sample of community-dwelling older adults. As expected, levels of social support given were associated with lower morbidity, whereas levels of receiving were not. It is important that these relations held even when (a) socioeconomic status, education, marital status, age, gender, ethnicity, and (b) absolute network size and activity limitation were controlled for. Results are discussed in terms of their implications for theory regarding the relations among social exchanges, giving, and later life adaptation among older adults.

Airborne surveys in the Arctic and Antarctic for geophysics, sea-ice thickness, and CryoSat validation

Airborne laser and radar measurements over the Greenland ice sheet, Svalbard, and adjacent parts of the Arctic Ocean have been carried out by DTU-Space in a number of recent Danish/Greenlandic and European project campaigns, with the purpose to monitor ice sheet and sea-ice changes, support of Greenland societal needs (oil exploration and hydropower), and support of CryoSat pre-launch calibration and validation campaigns. The Arctic campaigns have been done using a Twin-Otter aircraft, carrying laser scanners and various radars. Since 2009 a new program of long-range gravity and magnetic surveys have been initiated using a Basler DC3 aircraft for large-scale surveys in the Arctic Ocean and Antarctica, with the 2010 cooperative Danish-Argentinean-Chilean-US ICEGRAV survey of the Antarctic Peninsula additionally including a UTIG 60 MHz ice-penetrating radar. In the paper we outline the recent and upcoming airborne survey activities, outline the usefulness of the airborne data for satellite validation (CryoSat and GOCE), and give examples of measurements and comparisons to satellite and in-situ data.

Solitons and vortices in two-dimensional discrete nonlinear Schrödinger systems with spatially modulated nonlinearity

Kevrekidis, P. G.; Malomed, Boris A.; Saxena, Avadh; ...

2015-04-07

We consider a two-dimensional (2D) generalization of a recently proposed model [Phys. Rev. E 88, 032905 (2013)], which gives rise to bright discrete solitons supported by the defocusing nonlinearity whose local strength grows from the center to the periphery. We explore the 2D model starting from the anticontinuum (AC) limit of vanishing coupling. In this limit, we can construct a wide variety of solutions including not only single-site excitations, but also dipole and quadrupole ones. Additionally, two separate families of solutions are explored: the usual “extended” unstaggered bright solitons, in which all sites are excited in the AC limit, withmore » the same sign across the lattice (they represent the most robust states supported by the lattice, their 1D counterparts being those considered as 1D bright solitons in the above-mentioned work), and the vortex cross, which is specific to the 2D setting. For all the existing states, we explore their stability (also analytically, when possible). As a result, typical scenarios of instability development are exhibited through direct simulations.« less

The linguistic demands of the Common Core State Standards for reading and writing informational text in the primary grades.

Roberts, Kathryn L

2012-05-01

Forty-five states and four U.S. territories have committed to implementing the new Common Core State Standards, with the goal of graduating students from our K-12 programs who are ready for college and careers. For many, the new standards represent a shift in genre focus, giving much more specific attention to informational genres. Beginning in the primary grades, the standards set high expectations for students' interaction with informational text, many of which are significantly more linguistically demanding than the standards that they replace. These increased demands are likely to pose difficulties not only for students currently receiving language support, but also for students without identified delays or disabilities. This article describes several of the kindergarten through fifth-grade standards related to informational text, highlighting the linguistic demands that each poses. In addition, instructional strategies are provided that teachers and speech-language pathologists can use to support the understanding and formulation of informational text for listening, reading, speaking, and writing.

Induction of novel macroscopic properties by local symmetry violations in spin-spiral multiferroics

NASA Astrophysics Data System (ADS)

Meier, D.; Leo, N.; Becker, P.; Bohaty, L.; Ramesh, R.; Fiebig, M.

2011-03-01

Incommensurate (IC) structures are omnipresent in strongly correlated electron systems as high-TC superconductors, CMR manganites, as well as multiferroics. In each case they are origin of a pronounced symmetry reduction reflecting the complexity of the underlying microscopic interactions. Macroscopically, this can lead to new phases and possibilities to gain control of the host material. Here we report how the IC nature of a spin-spiral multiferroic induces new physical properties by renormalizing the relevant length scales of the system. Local symmetry violations directly manifest in the macroscopic response of the material and co-determine the multiferroic order giving rise to additional domain states. These usually hidden degrees of freedom become visible when non-homogenous fields are applied and condition for instance the second harmonic generation. Our study shows that incommensurabilities play a vital role in the discussion of the physical properties of multiferroics -- they represent a key ingredient for further enhancing the functionality of this class of materials.

The Roles of Vitamin C in Skin Health.

PubMed

Pullar, Juliet M; Carr, Anitra C; Vissers, Margreet C M

2017-08-12

The primary function of the skin is to act as a barrier against insults from the environment, and its unique structure reflects this. The skin is composed of two layers: the epidermal outer layer is highly cellular and provides the barrier function, and the inner dermal layer ensures strength and elasticity and gives nutritional support to the epidermis. Normal skin contains high concentrations of vitamin C, which supports important and well-known functions, stimulating collagen synthesis and assisting in antioxidant protection against UV-induced photodamage. This knowledge is often used as a rationale for the addition of vitamin C to topical applications, but the efficacy of such treatment, as opposed to optimising dietary vitamin C intake, is poorly understood. This review discusses the potential roles for vitamin C in skin health and summarises the in vitro and in vivo research to date. We compare the efficacy of nutritional intake of vitamin C versus topical application, identify the areas where lack of evidence limits our understanding of the potential benefits of vitamin C on skin health, and suggest which skin properties are most likely to benefit from improved nutritional vitamin C intake.

Collective philanthropy: describing and modeling the ecology of giving.

Gottesman, William L; Reagan, Andrew James; Dodds, Peter Sheridan

2014-01-01

Reflective of income and wealth distributions, philanthropic gifting appears to follow an approximate power-law size distribution as measured by the size of gifts received by individual institutions. We explore the ecology of gifting by analysing data sets of individual gifts for a diverse group of institutions dedicated to education, medicine, art, public support, and religion. We find that the detailed forms of gift-size distributions differ across but are relatively constant within charity categories. We construct a model for how a donor's income affects their giving preferences in different charity categories, offering a mechanistic explanation for variations in institutional gift-size distributions. We discuss how knowledge of gift-sized distributions may be used to assess an institution's gift-giving profile, to help set fundraising goals, and to design an institution-specific giving pyramid.

Seeking harmony in the provision of care to the stroke-impaired: views of Chinese family caregivers.

PubMed

Lee, Regina L T; Mok, Esther S B

2011-05-01

To explore the coping strategies of Chinese family caregivers of stroke-impaired older relatives. Many stroke-impaired patients rely heavily on support from their families, and the daily lives of such family caregivers are severely impacted. However, services and support for family caregivers of stroke-impaired relatives in the home setting have received little attention. Appropriate and relevant information and support to family caregivers are important in facilitating the care-giving task. It is, therefore, necessary to understand the nature and demands of care-giving before planning specific educational and support programmes. Grounded theory. Fifteen Chinese family caregivers of stroke-impaired older relatives were recruited and interviewed in 2003 and 2004. Theoretical sampling and constant comparative analysis were used to recruit the sample and perform data analysis. Seeking harmony to provide care for the stroke-impaired was the core category for describing and guiding the family care-giving process, with five main stages: (1) living with ambiguity, (2) monitoring the recovery progress, (3) accepting the downfalls, (4) meeting family obligations and (5) reconciling with harmony. These issues were seldom discussed openly with health professionals. The findings indicated that Chinese family caregivers determine their own needs by seeking harmony to continue to provide care without thinking about getting help from others or their own health problems. These findings help to define some of the complex dynamics that have an impact on the development of partnership care and might challenge nurses practising in the community. Community nurses should assess and understand the coping strategies of family caregivers and assist them to engage in stress-reducing practices. This is an important partnership to be formed in stroke care for family caregivers in the community. The study findings will guide further development of family care-giving aspects in nursing practice. © 2010 Blackwell Publishing Ltd.

Supportive leadership in Swedish community night nursing.

PubMed

Gustafsson, Christine; Fagerberg, Ingegerd; Asp, Margareta

2010-10-01

The aim of the present study was to examine the support night nurses' give to staff in community night nursing. Studies have shown that support given to staff is one of night registered nurses' (RNs') experiences of the meaning of caring. This support, that community RNs display for staff in night-time care, is sparsely described. All community night-duty nurses in a medium-sized municipal in Sweden participated in the present study. Thematic content analysis was used to analyse data from observations. The support given by RNs to staff is described using three themes: (1) a conditional supporting stance, (2) preparing propitious conditions for caring and (3) confidence in the abilities of individual staff members and adaptation to their individual needs. The results reveal that RNs consider support to staff in terms of nursing leadership. Out of 'concern for the staff' the RNs try to be there for them, which corresponds to nursing leadership. Such concern also arises from the RNs' awareness that by giving support to staff this affects the staffs' caring for older people. The current municipal social care organization of community nursing of older people in which RNs have extensive responsibilities with insufficient control, is a working condition with a risk for decreased quality of care and a high risk for work-related stress syndrome. © 2010 The Authors.

The Blood Donation Ambivalence Survey: measuring conflicting attitudes about giving blood.

PubMed

Fox, K R; Himawan, L K; France, C R

2017-05-18

This study was designed to develop and conduct initial validation testing for a novel measure of ambivalence about donating blood. Previous studies of living organ, bone marrow and stem cell donors have identified donation-related ambivalence as a predictor of decisions about donation and post-donation outcomes. Ambivalence about blood donation has not received the same attention. In Study 1, a sample of young adults (N = 396) were administered test items of ambivalence, and exploratory (EFA) and confirmatory factor analyses (CFA) were performed to identify the Blood Donation Ambivalence Survey. In Study 2, a separate sample of young adults (N = 241) completed the Blood Donation Ambivalence Survey in addition to questionnaires assessing known predictors of blood donation. Exploratory and confirmatory factor analyses indicated a two-factor structure reflecting commitment to donating blood and indecision about giving blood. The commitment subscale was positively related to known predictors of increased donation behaviour (e.g. donation intention, self-efficacy), whereas the indecision subscale was positively related to known predictors of decreased donation behaviour (e.g. donation anxiety, negative affect). Furthermore, a history of blood donation was associated with greater commitment and less indecision. The present findings provide strong initial support for the reliability and validity of a novel measure of blood donor ambivalence. © 2017 British Blood Transfusion Society.

Localised electrochemical impedance measurements of a polymer electrolyte fuel cell using a reference electrode array to give cathode-specific measurements and examine membrane hydration dynamics

Advances in bespoke diagnostic techniques for polymer electrolyte fuel cells continue to provide unique insight into the internal operation of these devices and lead to improved performance and durability. Localised measurements of current density have proven to be extremely useful in designing better fuel cells and identifying optimal operating strategies, with electrochemical impedance spectroscopy (EIS) now routinely used to deconvolute the various losses in fuel cells. Combining the two techniques provides another dimension of understanding, but until now each localised EIS has been based on 2-electrode measurements, composed of both the anode and cathode responses. This work shows that a reference electrode array can be used to give individual electrode-specific EIS responses, in this case the cathode is focused on to demonstrate the approach. In addition, membrane hydration dynamics are studied under current load steps from open circuit voltage. A three-stage process is identified associated with an initial rapid reduction in membrane resistance after 10 s of applying a current step, followed by a slower ramp to approximately steady state, which was achieved after ∼250 s. These results support previously published work that has looked at membrane swelling dynamics and reveal that membrane hydration/membrane resistance is highly heterogeneous.

The National Research Agenda (NWA) assembles topics on which scientist can focus in the coming years. A study carried out by de Radboudumc in Nijmegen examined how many questions are put to the NWA on dementia and ageing. What priority does society give to this research field and who ask questions about this? With the method of the NWA as reference frame a supplementary route on dementia/ageing was proposed. Of the 11.700 questions submitted to the NWA almost 2.5% is about dementia/ageing. Compared to other medical issues this is a relatively high percentage. This analysis provides 21 research questions which give a good idea of the questions that where asked about the themes of ageing and dementia. Half of the questions came from citizens, therefore we can speak of a socially supported agenda in this area. However, most of the valid questions came from professional organizations involved in dementia. In the Netherlands a relatively high priority is given by authors of questions for the NWA to research on dementia and ageing. Questions from professionals are complemented by citizens who ask other relevant questions that provide a new perspective and are an addition to the knowledge questions from scientists.

Applied adaptive disturbance rejection using output redefinition on magnetic bearings

NASA Astrophysics Data System (ADS)

Matras, Alex Logan

Recent work has shown Adaptive Disturbance Rejection to be an effective technique for rejecting forces due to imbalance, runout and base motion disturbances on flywheels supported by magnetic bearings over a large span of frequencies. Often the applicability of some of the adaptive methods is limited because they require certain properties (such as almost-strict positive realness) that magnetic bearings do not possess. In this thesis, one method for adaptive disturbance rejection, called Adaptive Feedforward Cancellation (AFC), is modified to allow for a much wider range of frequencies to be rejected. This is accomplished by redefining the output of the original system to be the output from a reduced order state estimator instead. This can give a new system with an infinite gain margin. Additionally, the adaptation laws for the two disturbance rejection gains are slightly modified so that each adapts to a different signal in order to provide the best performance. A detailed model of a magnetic bearing is developed and computer simulations based on that model are performed to give an initial test of the new control law. A state-of-the-art magnetic bearing setup is then developed and used to implement the new control laws and determine their effectiveness. The results are successful and validate the new ideas that are presented.

A glance through the Harvard Business Review reveals many suggestions and research pieces reviewing sales and marketing techniques. Most educators will be familiar with the notion that making accurate first impressions and being responsive, whilst maintaining pace is critical to engaging an audience. There are lessons to be learnt from industry that can significantly impact upon our teaching. Eisenkraft, in his address to the NSTA, proposed four essential questions. This presentation explores one of those questions: 'Why should I care?', and discusses why this question is crucial for engaging students by giving a clear purpose for developing their scientific understanding. Additionally, this presentation explores how The ISF Academy has adapted the NGSS, using the 14 Grand Engineering Challenges and the IB MYP, to provide current, authentic global contexts, in order to give credibility to the concepts, understandings and skills being learnt. The provision of global contexts across units and within lessons supports a platform for students to have the freedom to explore their own sense of social responsibility. The Science Department believes that planning lessons with tasks that elaborate on the student's new conceptualisations, has helped to transfer the student's new understanding into social behavior beyond the classroom. Furthermore, extension tasks have been used to transfer conceptual understanding between different global contexts.

The vascular cambium is the meristem in trees that produce wood. This meristem consists of two types of neighbouring initials: fusiform cambial cells (FCCs), which give rise to the axial cell system (i.e. fibres and vessel elements), and ray cambial cells (RCCs), which give rise to rays. There is little molecular information on the mechanisms whereby the differing characteristics of these neighbouring cells are maintained. A microgenomic approach was adopted in which the transcriptomes of FCCs and RCCs dissected out from the cambial meristem of poplar (Populus trichocarpa x Populus deltoïdes var. Boelare) were analysed, and a transcriptional database for these two cell types established. Photosynthesis genes were overrepresented in RCCs, providing molecular support for the presence of photosynthetic systems in rays. Genes that putatively encode transporters (vesicle, lipid and metal ion transporters and aquaporins) in RCCs were also identified. In addition, many cell wall-related genes showed cell type-specific expression patterns. Notably, genes involved in pectin metabolism and xyloglucan metabolism were overrepresented in RCCs and FCCs, respectively. The results demonstrate the use of microgenomics to reveal differences in biological processes in neighbouring meristematic cells, and to identify key genes involved in these processes.

Born approximation for scattering by evanescent waves: Comparison with exact scattering by an infinite fluid cylinder

NASA Astrophysics Data System (ADS)

Marston, Philip L.

2004-05-01

In some situations, evanescent waves can be an important component of the acoustic field within the sea bottom. For this reason (as well as to advance the understanding of scattering processes) it can be helpful to examine the modifications to scattering theory resulting from evanescence. Modifications to ray theory were examined in a prior approximation [P. L. Marston, J. Acoust. Soc. Am. 113, 2320 (2003)]. The new research concerns the modifications to the low-frequency Born approximation and confirmation by comparison with the exact two-dimensional scattering by a fluid cylinder. In the case of a circular cylinder having the same density as the surroundings but having a compressibility contrast with the surroundings, the Born approximation with a nonevanescent incident wave gives only monopole scattering. When the cylinder has a density contrast and the same compressibility as the surroundings the regular Born approximation gives only dipole scattering (with the dipole oriented along to the incident wavevector). In both cases when the Born approximation is modified to include the evanescence of the incident wave, an additional dipole scattering term is evident. In each case the new dipole is oriented along to the decay axis of the evanescent wave. [Research supported by ONR.

Hřivnáčová, Ivana

2014-06-01

g4tools, that is originally part of the inlib and exlib packages, provides a very light and easy to install set of C++ classes that can be used to perform analysis in a Geant4 batch program. It allows to create and manipulate histograms and ntuples, and write them in supported file formats (ROOT, AIDA XML, CSV and HBOOK). It is integrated in Geant4 through analysis manager classes, thus providing a uniform interface to the g4tools objects and also hiding the differences between the classes for different supported output formats. Moreover, additional features, such as for example histogram activation or support for Geant4 units, are implemented in the analysis classes following users requests. A set of Geant4 user interface commands allows the user to create histograms and set their properties interactively or in Geant4 macros. g4tools was first introduced in the Geant4 9.5 release where its use was demonstrated in one basic example, and it is already used in a majority of the Geant4 examples within the Geant4 9.6 release. In this paper, we will give an overview and the present status of the integration of g4tools in Geant4 and report on upcoming new features.

This study was conducted to examine changes in women's mental health over the first postpartum year and factors that are associated with mental health. Participants included women who were married, employed, English-speaking, and giving birth to their first child at one of two hospitals in St Paul, Minnesota. Women who were eligible and willing to participate were mailed questionnaires at 1, 3, 6, 9, and 12 months postpartum. There were significant changes in mothers' general mental health, depression, and anxiety over the first postpartum year (P < or = .01), with least favorable outcomes at 1 month and most favorable outcomes at 12 months postpartum. Poor mental health was related to work factors, such as longer work hours and maternity leave of less than 24 weeks, and to variables often associated with recent childbirth, such as maternal fatigue, loss of sleep, concerns about appearance, and infant illnesses. In addition, postpartum symptoms were predicted by physical illness, previous mental problems, poor general health, poor social support, fewer recreational activities, young age, and low income (R2 = 37% to 57%). In this select group of women, postpartum mental health was found to be least favorable 1 month after delivery and related to factors associated with employment, recent delivery, and level of social support.

[The elderly and their pets. Supportive and problematic aspects and implications for care. A descriptive study].

Graf, S

Pet ownership by elderly people is very common. This phenomenological study investigated why elderly people keep pets and what illness of the animals or their loss means to them. Nine women and three men owning either cats, dogs, or birds participated in this study. Their average age was 84. The results confirm on the one hand that elderly people experience happiness and joy thanks to having pets, giving them an ingenious social function as well as helping overcome the frequent passivity of old age. The problems arising with the ownership of animals are accident endangering (falls) and overexertion. An additional concern is the support of the animals during illness of the owner. The loss of animals is often connected with serious grief reaction and disorganisation of daily life. Serious, long-lasting, and pathological grief reactions were shown after a forced separation from the pet. Four recommendations for nursing practice resulted from this study: to approve and support the ownership of pets and domestic animals as a factor of the "good old age"; to accept the pets as part of the 'family' and integrate them into nursing work, to encourage the owner to plan the future of the pet. Finally, to help overcome the loss of pets and animals a specific nursing therapeutic treatment is required.

Epilepsy is a neurological disorder produced due to abnormal excitability of neurons in the brain. The research reveals that brain activity is monitored through electroencephalogram (EEG) of patients suffered from seizure to detect the epileptic seizure. The performance of EEG detection based epilepsy require feature extracting strategies. In this research, we have extracted varying features extracting strategies based on time and frequency domain characteristics, nonlinear, wavelet based entropy and few statistical features. A deeper study was undertaken using novel machine learning classifiers by considering multiple factors. The support vector machine kernels are evaluated based on multiclass kernel and box constraint level. Likewise, for K-nearest neighbors (KNN), we computed the different distance metrics, Neighbor weights and Neighbors. Similarly, the decision trees we tuned the paramours based on maximum splits and split criteria and ensemble classifiers are evaluated based on different ensemble methods and learning rate. For training/testing tenfold Cross validation was employed and performance was evaluated in form of TPR, NPR, PPV, accuracy and AUC. In this research, a deeper analysis approach was performed using diverse features extracting strategies using robust machine learning classifiers with more advanced optimal options. Support Vector Machine linear kernel and KNN with City block distance metric give the overall highest accuracy of 99.5% which was higher than using the default parameters for these classifiers. Moreover, highest separation (AUC = 0.9991, 0.9990) were obtained at different kernel scales using SVM. Additionally, the K-nearest neighbors with inverse squared distance weight give higher performance at different Neighbors. Moreover, to distinguish the postictal heart rate oscillations from epileptic ictal subjects, and highest performance of 100% was obtained using different machine learning classifiers.

Human heme oxygenase oxidation of 5- and 15-phenylhemes.

Human heme oxygenase-1 (hHO-1) catalyzes the O2-dependent oxidation of heme to biliverdin, CO, and free iron. Previous work indicated that electrophilic addition of the terminal oxygen of the ferric hydroperoxo complex to the alpha-meso-carbon gives 5-hydroxyheme. Earlier efforts to block this reaction with a 5-methyl substituent failed, as the reaction still gave biliverdin IXalpha. Surprisingly, a 15-methyl substituent caused exclusive cleavage at the gamma-meso-rather than at the normal, unsubstituted alpha-meso-carbon. No CO was formed in these reactions, but the fragment cleaved from the porphyrin eluded identification. We report here that hHO-1 cleaves 5-phenylheme to biliverdin IXalpha and oxidizes 15-phenylheme at the alpha-meso position to give 10-phenylbiliverdin IXalpha. The fragment extruded in the oxidation of 5-phenylheme is benzoic acid, one oxygen of which comes from O2 and the other from water. The 2.29- and 2.11-A crystal structures of the hHO-1 complexes with 1- and 15-phenylheme, respectively, show clear electron density for both the 5- and 15-phenyl rings in both molecules of the asymmetric unit. The overall structure of 15-phenylheme-hHO-1 is similar to that of heme-hHO-1 except for small changes in distal residues 141-150 and in the proximal Lys18 and Lys22. In the 5-phenylheme-hHO-1 structure, the phenyl-substituted heme occupies the same position as heme in the heme-HO-1 complex but the 5-phenyl substituent disrupts the rigid hydrophobic wall of residues Met34, Phe214, and residues 26-42 near the alpha-meso carbon. The results provide independent support for an electrophilic oxidation mechanism and support a role for stereochemical control of the reaction regiospecificity.

As a successful female scientist with two ERC grants, first as a starter and now a consolidator, I was priviliged that I personally never perceived any obstacles. At the same time, I am also aware that the statistics tell a different story when you look at the whole population. I will give an account and tell some anecdotes about what I think helped me, though it is important to be careful not to generalise my personal strategies. My main strategy is to publish papers in international journals and obtain personal grants. This also means limiting additional responsibilities that will not benefit my publication record or potential success in grant applications. The second important factor is that I have always been surrounded by people who give me confidence and support me, such as my parents, partner and senior colleagues who have acted (mostly unofficially) as mentor. In the workplace, there is a great advantage in having a senior mentor, who needs to be a successful academic(!), and can help with any career related issues and choices. But also at home, a supportive partner who will take an equal share in childcare responsibilities, makes a great difference. Are there any new strategies that we can implement to further overcome barriers? Not by design, but by coincidence, my research team for my ERC starting grant consisted largely of female PhD students and postdocs. The great things was that they stimulated each other, all became very confident, and several of them now have academics jobs at prestigious universities in the US and Europe. They believe in themselves, which is the first step in overcoming any potential barriers they may encounter later in their careers.

To investigate the benefits in reported outcomes after providing bluetooth accessories for established hearing aid users. Prospective observational study using validated quantitative outcome measures and detailed patient narrative before and two months after patients were provided with bluetooth accessories. Twelve patients with bilateral NHS hearing aids participated. They had a wide range of ages and hearing loss. After two months, 10 patients reported substantial additional benefit and kept the accessories; two returned them for various reasons. Statistically significant changes were seen in two validated outcome measures: the Glasgow Hearing Aid Benefit Profile and the International Outcome Inventory - Hearing Aids, but not in the Speech, Spatial and Qualities of Hearing Scale. Two notable benefits were reported: some described hearing the emotion and mood in a voice for the first time; others were amazed to report an improved ability to hear film or to hold conversations over the telephone. The provision of bluetooth accessories can give additional reported benefit for some patients - we need better knowledge about who benefits, and whether further support/training to individuals would make a difference.

Hydrogen production by steam reforming of liquefied natural gas (LNG) over nickel catalysts supported on cationic surfactant-templated mesoporous aluminas

NASA Astrophysics Data System (ADS)

Seo, Jeong Gil; Youn, Min Hye; Park, Sunyoung; Jung, Ji Chul; Kim, Pil; Chung, Jin Suk; Song, In Kyu

Two types of mesoporous γ-aluminas (denoted as A-A and A-S) are prepared by a hydrothermal method under different basic conditions using cationic surfactant (cetyltrimethylammonium bromide, CTAB) as a templating agent. A-A and A-S are synthesized in a medium of ammonia solution and sodium hydroxide solution, respectively. Ni/γ-Al 2O 3 catalysts (Ni/A-A and Ni/A-S) are then prepared by an impregnation method, and are applied to hydrogen production by steam reforming of liquefied natural gas (LNG). The effect of a mesoporous γ-Al 2O 3 support on the catalytic performance of Ni/γ-Al 2O 3 is investigated. The identity of basic solution strongly affects the physical properties of the A-A and A-S supports. The high surface-area of the mesoporous γ-aluminas and the strong metal-support interaction of supported catalysts greatly enhance the dispersion of nickel species on the catalyst surface. The well-developed mesopores of the Ni/A-A and Ni/A-S catalysts prohibit the polymerization of carbon species on the catalyst surface during the reaction. In the steam reforming of LNG, both Ni/A-A and Ni/A-S catalysts give better catalytic performance than the nickel catalyst supported on commercial γ-Al 2O 3 (Ni/A-C). In addition, the Ni/A-A catalyst is superior to the Ni/A-S catalyst. The relatively strong metal-support interaction of Ni/A-A catalyst effectively suppresses the sintering of metallic nickel and the carbon deposition in the steam reforming of LNG. The large pores of the Ni/A-A catalyst also play an important role in enhancing internal mass transfer during the reaction.

Psychosocial impacts on caregivers of people living with AIDS.

Estimates show that by 2010 up to six million South Africans will be HIV-infected. Simultaneously, public health care resources are overstretched and communities and families are taking more responsibility for providing care. However, little work in South Africa has investigated the possible psychosocial impacts on caregivers. This study investigates psychosocial impacts at household level with reference to gender, programme, and policy implications. Forty-five in-depth interviews were held with primary caregivers of people living with AIDS (PWA). Participants were recruited using purposive and snowball sampling. Forty-three respondents were women, signifying that gender is an important issue in this context. Data were analysed using a grounded theory approach. Care giving placed considerable demands on caregivers, which was exacerbated by insufficient support, dire poverty and the added responsibilities of caring for other household members. Lack of basic resources was common and chronic, and care giving impacted negatively on employment and social life. Stigma and prejudice towards caregivers was common and exacerbated stress levels. Assessment of support received from various sources ranged widely. The lack of support was often debilitating. Respondents who felt supported linked this support to improved psychosocial status. Recommendations for policy on home-based care are outlined.

Laser surgery gives the possibility to work remotely which leads to high precision, little trauma and high level sterility. However these advantages are coming with the lack of haptic feedback during the laser ablation of tissue. Therefore additional means are required to control tissue-specific ablation during laser surgery supporting the surgeon regardless of experience and skills. Diffuse Reflectance Spectroscopy provides a straightforward and simple approach for optical tissue differentiation. We measured diffuse reflectance from four various tissue types ex vivo. We applied Linear Discriminant Analysis (LDA) to differentiate the four tissue types and computed the area under the ROC curve (AUC). Special emphasis was taken on the identification of nerve as the most crucial tissue for maxillofacial surgery. The results show a promise for differentiating soft tissues as guidance for tissue-specific laser surgery by means of the diffuse reflectance.

Guided Iterative Substructure Search (GI-SSS) - A New Trick for an Old Dog.

PubMed

Weskamp, Nils

2016-07-01

Substructure search (SSS) is a fundamental technique supported by various chemical information systems. Many users apply it in an iterative manner: they modify their queries to shape the composition of the retrieved hit sets according to their needs. We propose and evaluate two heuristic extensions of SSS aimed at simplifying these iterative query modifications by collecting additional information during query processing and visualizing this information in an intuitive way. This gives the user a convenient feedback on how certain changes to the query would affect the retrieved hit set and reduces the number of trial-and-error cycles needed to generate an optimal search result. The proposed heuristics are simple, yet surprisingly effective and can be easily added to existing SSS implementations. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

A Bayesian network coding scheme for annotating biomedical information presented to genetic counseling clients.

Green, Nancy

2005-04-01

We developed a Bayesian network coding scheme for annotating biomedical content in layperson-oriented clinical genetics documents. The coding scheme supports the representation of probabilistic and causal relationships among concepts in this domain, at a high enough level of abstraction to capture commonalities among genetic processes and their relationship to health. We are using the coding scheme to annotate a corpus of genetic counseling patient letters as part of the requirements analysis and knowledge acquisition phase of a natural language generation project. This paper describes the coding scheme and presents an evaluation of intercoder reliability for its tag set. In addition to giving examples of use of the coding scheme for analysis of discourse and linguistic features in this genre, we suggest other uses for it in analysis of layperson-oriented text and dialogue in medical communication.

Voting at 16: Turnout and the quality of vote choice.

Wagner, Markus; Johann, David; Kritzinger, Sylvia

2012-06-01

Critics of giving citizens under 18 the right to vote argue that such teenagers lack the ability and motivation to participate effectively in elections. If this argument is true, lowering the voting age would have negative consequences for the quality of democracy. We test the argument using survey data from Austria, the only European country with a voting age of 16 in nation-wide elections. While the turnout levels of young people under 18 are relatively low, their failure to vote cannot be explained by a lower ability or motivation to participate. In addition, the quality of these citizens' choices is similar to that of older voters, so they do cast votes in ways that enable their interests to be represented equally well. These results are encouraging for supporters of a lower voting age.

The new research group on the four-dimensional research and communication of urban history (Urban History 4D) aims to investigate and develop methods and technologies to access extensive repositories of historical media and their contextual information in a spatial model, with an additional temporal component. This will make content accessible to different target groups, researchers and the public, via a 4D browser. A location-dependent augmented-reality representation can be used as an information base, research tool, and means of communicating historical knowledge. The data resources for this research include extensive holdings of historical photographs of Dresden, which have documented the city over the decades, and digitized map collections from the Deutsche Fotothek (German photographic collection) platform. These will lay the foundation for a prototype model which will give users a virtual experience of historic parts of Dresden.

Simulations to study the static polarization limit for RHIC lattice

Duan, Zhe; Qin, Qing

2016-01-01

A study of spin dynamics based on simulations with the Polymorphic Tracking Code (PTC) is reported, exploring the dependence of the static polarization limit on various beam parameters and lattice settings for a practical RHIC lattice. It is shown that the behavior of the static polarization limit is dominantly affected by the vertical motion, while the effect of beam-beam interaction is small. In addition, the “nonresonant beam polarization” observed and studied in the lattice-independent model is also observed in this lattice-dependent model. Therefore, this simulation study gives insights of polarization evolution at fixed beam energies, that are not available in simple spin tracking.

Moral vindications.

PubMed

Kumar, Victor

2017-10-01

Psychologists and neuroscientists have recently been unearthing the unconscious processes that give rise to moral intuitions and emotions. According to skeptics like Joshua Greene, what has been found casts doubt on many of our moral beliefs. However, a new approach in moral psychology develops a learning-theoretic framework that has been successfully applied in a number of other domains. This framework suggests that model-based learning shapes intuitions and emotions. Model-based learning explains how moral thought and feeling are attuned to local material and social conditions. Philosophers can draw on these explanations, in some cases, in order to vindicate episodes of moral change. Explanations can support justifications by showing that they are not mere rationalizations. In addition, philosophical justifications are a fertile source for empirical hypotheses about the rational learning mechanisms that shape moral intuitions and emotions. Copyright © 2017 Elsevier B.V.

Constant Stress Drop Fits Earthquake Surface Slip-Length Data

NASA Astrophysics Data System (ADS)

Shaw, B. E.

2011-12-01

Slip at the surface of the Earth provides a direct window into the earthquake source. A longstanding controversy surrounds the scaling of average surface slip with rupture length, which shows the puzzling feature of continuing to increase with rupture length for lengths many times the seismogenic width. Here we show that a more careful treatment of how ruptures transition from small circular ruptures to large rectangular ruptures combined with an assumption of constant stress drop provides a new scaling law for slip versus length which (1) does an excellent job fitting the data, (2) gives an explanation for the large crossover lengthscale at which slip begins to saturate, and (3) supports constant stress drop scaling which matches that seen for small earthquakes. We additionally discuss how the new scaling can be usefully applied to seismic hazard estimates.

The principle of stereotopic face differentiation was successfully applied to 2H-phospholes which undergo a very efficient and highly stereoselective Diels-Alder reaction giving phosphorus-chiral 1-phosphanorbornenes with up to 87% yield. The observed reaction pathway has been supported by theoretical calculations showing that the cycloaddition reaction between 2H-phosphole 3a and the dienophile (5R)-(-)-menthyloxy-2(5H)-furanone (8) is of normal electron demand. Optically pure phosphanes were obtained by separation of the single diastereomers and subsequent desulfurisation of the sulfur-protected phosphorus atom. Finally, divergent ligand synthesis is feasible by reduction of the chiral auxiliary, subsequent stereospecific intramolecular Michael addition, and various functionalisations of the obtained key compound 13a. Furthermore, the unique structural properties of phospanorbornenes are presented and compared to those of phosphanorbornanes.

DEALING WITH DENTAL IMPLANT FAILURES

PubMed Central

Levin, Liran

2008-01-01

An implant-supported restoration offers a predictable treatment for tooth replacement. Reported success rates for dental implants are high. Nevertheless, failures that mandate immediate implant removal do occur. The consequences of implant removal jeopardize the clinician's efforts to accomplish satisfactory function and esthetics. For the patient, this usually involves further cost and additional procedures. The aim of this paper is to describe different methods and treatment modalities to deal with dental implant failure. The main topics for discussion include identifying the failing implant, implants replacing failed implants at the exact site, and the use of other restorative options. When an implant fails, a tailor made treatment plan should be provided to each patient according to all relevant variables. Patients should be informed regarding all possible treatment modalities following implant failure and give their consent to the most appropriate treatment option for them. PMID:19089213

Modeling waves forced by a drop bouncing on a vibrating bath

Turton, Sam; Rosales, Ruben; Bush, John

2017-11-01

We study the wavefield generated by a droplet bouncing on a bath of silicon oil undergoing vertical oscillations. Such droplets may bounce indefinitely below the Faraday threshold, and in certain parameter regimes destabilize into a walking state in which they are propelled by their own wavefield. While previous theoretical models have rationalize the behavior of single droplets, difficulties have arisen in rationalizing the behavior of multi-droplet systems. We here present a refined wave model that allows us to do so. In particular, we give a detailed account of the spatio-temporal decay of the waves, in addition to the couping between the wave amplitude and modulations in the droplet's vertical dynamics. Our analytic model is compared with the results of direct numerical simulations and experiments. We gratefully acknowledge the financial support of the NSF.

Phase-dependent noise in Josephson junctions

NASA Astrophysics Data System (ADS)

Sheldon, Forrest; Peotta, Sebastiano; Di Ventra, Massimiliano

2018-03-01

In addition to the usual superconducting current, Josephson junctions (JJs) support a phase-dependent conductance related to the retardation effect of tunneling quasi-particles. This introduces a dissipative current with a memory-resistive (memristive) character that should also affect the current noise. By means of the microscopic theory of tunnel junctions we compute the complete current autocorrelation function of a Josephson tunnel junction and show that this memristive component gives rise to both a previously noted phase-dependent thermal noise, and an undescribed non-stationary, phase-dependent dynamic noise. As experiments are approaching ranges in which these effects may be observed, we examine the form and magnitude of these processes. Their phase dependence can be realized experimentally as a hysteresis effect and may be used to probe defects present in JJ based qubits and in other superconducting electronics applications.

Review: Genetically modified plants for the promotion of human health.

Yonekura-Sakakibara, Keiko; Saito, Kazuki

2006-12-01

Plants are attractive biological resources because of their ability to produce a huge variety of chemical compounds, and the familiarity of production in even the most rural settings. Genetic engineering gives plants additional characteristics and value for cultivation and post-harvest. Genetically modified (GM) plants of the "first generation" were conferred with traits beneficial to producers, whereas GM plants in subsequent "generations" are intended to provide beneficial traits for consumers. Golden Rice is a promising example of a GM plant in the second generation, and has overcome a number of obstacles for practical use. Furthermore, consumer-acceptable plants with health-promoting properties that are genetically modified using native genes are being developed. The emerging technology of metabolomics will also support the commercial realization of GM plants by providing comprehensive analyzes of plant biochemical components.

Human behaviors always related to day routine activities in a smart house directly give the significant factor to manage energy usage in human life. An Addition that, the factor will contribute to the best efficiency of the system. This paper will focus on the monitoring efficiency based on duration time in office hours around 8am until 5pm which depend on human behavior at working place. Besides that, the correlation coefficient method is used to show the relation between energy consumption and energy saving based on the total hours of time energy spent. In future, the percentages of energy monitoring system usage will be increase to manage energy saving based on human behaviors. This scenario will help to see the human activity in the workplace in order to get the energy saving and support world green environment.

Impact of active phase chemical composition and dispersity on catalytic behavior in PROX reaction

NASA Astrophysics Data System (ADS)

Cherkezova-Zheleva, Z.; Paneva, D.; Todorova, S.; Kolev, H.; Shopska, M.; Yordanova, I.; Mitov, I.

Iron and iron-platinum catalysts supported on activated carbon have been successfully synthesized by wet impregnation method and low-temperature treatment in inert atmosphere. The content of the supported phases corresponds to 10 wt % Fe and 0.5 wt % Pt. Four catalytic samples were synthesized: Sample A—activated carbon impregnated with Fe nitrate; Sample B—activated carbon impregnated with Pt salt; Sample C—activated carbon impregnated consequently with Fe and Pt salts; Sample D—activated carbon impregnated simultaneously with Fe and Pt salts. The as-prepared materials were characterized by Mössbauer spectroscopy, X-ray diffraction, infrared and X-ray photoelectron spectroscopy. The spectra show that the activated carbon support and the preparation procedure give rise to the synthesis of isolated metal Pt ions and ultradispersed Fe and Pt oxide species. Probably the presence of different functional groups of activated carbon gives rise to registered very high dispersion of loaded species on support. The catalytic tests were carried out in PROX reaction. A lower activity of bimetallic Pt-Fe samples was explained with the increase in surface oxygen species as a result of predomination of iron oxide on the support leading to the increase in selectivity to the H2 oxidation. Partial agglomeration of supported iron oxide phase was registered after catalytic tests.

Giving parents a voice: A qualitative study of the challenges experienced by parents of children with disabilities.

PubMed

Resch, J Aaron; Mireles, Gerardo; Benz, Michael R; Grenwelge, Cheryl; Peterson, Rick; Zhang, Dalun

2010-05-01

This study sought to examine the specific sources of challenges as identified by parents of children with disabilities. Focus groups were conducted with 40 parent caregivers. Data gathered were coded into themes which were then analyzed through an intentional process of data reduction that resulted in the cross site validation of four superordinate themes. Four themes emerged as the most prominent barriers to positive parent wellbeing: (a) access to information and services, (b) financial barriers, (c) school and community inclusion, and (d) family support. These four themes are indicative of problems associated with a lack of match between caregiver needs and services, resources, or support available in the community to meet those needs. Caring for a child with a disability can be challenging, but many of these challenges are likely due to a lack of necessary environmental supports. Future research should expand on these findings and policy makers, scientists and providers should give particular attention to the environmental support needs of parents in order to create policies and interventions that are more family-centered.

The objective of this phenomenological study was to develop an understanding of family needs following the suicide of a teenager. Six parent units living in the Midwest who lost a teenager to suicide were interviewed. Participants indicated several key themes that describe a parent's needs following the suicide of a teenager. These needs were organized into 6 main categories: (a) support by listening and responding, (b) support from another suicide survivor, (c) support in finding direction, (d) support when viewing the deceased teen, (e) support in remembering the teen, and (f) support in parents giving back to the community.

Collective Philanthropy: Describing and Modeling the Ecology of Giving

PubMed Central

Gottesman, William L.; Reagan, Andrew James; Dodds, Peter Sheridan

2014-01-01

Reflective of income and wealth distributions, philanthropic gifting appears to follow an approximate power-law size distribution as measured by the size of gifts received by individual institutions. We explore the ecology of gifting by analysing data sets of individual gifts for a diverse group of institutions dedicated to education, medicine, art, public support, and religion. We find that the detailed forms of gift-size distributions differ across but are relatively constant within charity categories. We construct a model for how a donor's income affects their giving preferences in different charity categories, offering a mechanistic explanation for variations in institutional gift-size distributions. We discuss how knowledge of gift-sized distributions may be used to assess an institution's gift-giving profile, to help set fundraising goals, and to design an institution-specific giving pyramid.

Crown Ether Complexes of Alkali-Metal Chlorides from SO2.

PubMed

Reuter, Kirsten; Rudel, Stefan S; Buchner, Magnus R; Kraus, Florian; von Hänisch, Carsten

2017-07-18

The structures of alkali-metal chloride SO 2 solvates (Li-Cs) in conjunction with 12-crown-4 or 1,2-disila-12-crown-4 show strong discrepancies, despite the structural similarity of the ligands. Both types of crown ethers form 1:1 complexes with LiCl to give [Li(1,2-disila-12-crown-4)(SO 2 Cl)] (1) and [Li(12-crown-4)Cl]⋅4 SO 2 (2). However, 1,2-disila-12-crown-4 proved unable to coordinate cations too large for the cavity diameter, for example, by the formation of sandwich-type complexes. As a result, 12-crown-4 reacts exclusively with the heavier alkali-metal chlorides NaCl, KCl and RbCl. Compounds [Na(12-crown-4) 2 ]Cl⋅4 SO 2 (3) and [M(12-crown-4) 2 (SO 2 )]Cl⋅4 SO 2 (4: M=K; 5: M=Rb) all showed S-coordination to the chloride ions through four SO 2 molecules. Compounds 4 and 5 additionally exhibit the first crystallographically confirmed non-bridging O,O'-coordination mode of SO 2 . Unexpectedly, the disila-crown ether supports the dissolution of RbCl and CsCl in the solvent and gives the homoleptic SO 2 -solvated alkali-metal chlorides [MCl⋅3 SO 2 ] (6: M=Rb; 7: M=Cs), which incorporate bridging μ-O,O'-coordinating moieties and the unprecedented side-on O,O'-coordination mode. All compounds were characterised by single-crystal X-ray diffraction. The crown ether complexes were additionally studied by using NMR spectroscopy, and the presence of SO 2 at ambient temperature was revealed by IR spectroscopy of the neat compounds. © 2017 Wiley-VCH Verlag GmbH & Co.

The U.S. Geological Survey (USGS) resource assessment (Williams et al., 2008) outlined a mean 30 GWe of undiscovered hydrothermal resource in the western United States. One goal of the U.S. Department of Energy's (DOE) Geothermal Technology Office (GTO) is to accelerate the development of this undiscovered resource. DOE has focused efforts on helping industry identify hidden geothermal resources to increase geothermal capacity in the near term. Increased exploration activity will produce more prospects, more discoveries, and more readily developable resources. Detailed exploration case studies akin to those found in oil and gas (e.g. Beaumont and Foster, 1990-1992) will give developersmore » central location for information gives models for identifying new geothermal areas, and guide efficient exploration and development of these areas. To support this effort, the National Renewable Energy Laboratory (NREL) has been working with GTO to develop a template for geothermal case studies on the Geothermal Gateway on OpenEI. In 2012, the template was developed and tested with two case studies: Raft River Geothermal Area (http://en.openei.org/wiki/Raft_River_Geothermal_Area) and Coso Geothermal Area (http://en.openei.org/wiki/Coso_Geothermal_Area). In 2013, ten additional case studies were completed, and Semantic MediaWiki features were developed to allow for more data and the direct citations of these data. These case studies are now in the process of external peer review. In 2014, NREL is working with universities and industry partners to populate additional case studies on OpenEI. The goal is to provide a large enough data set to start conducting analyses of exploration programs to identify correlations between successful exploration plans for areas with similar geologic occurrence models.« less

Can nonstandard interactions jeopardize the hierarchy sensitivity of DUNE?

NASA Astrophysics Data System (ADS)

Deepthi, K. N.; Goswami, Srubabati; Nath, Newton

2017-10-01

We study the effect of nonstandard interactions (NSIs) on the propagation of neutrinos through the Earth's matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize the special case when the diagonal NSI parameter ɛe e=-1 , nullifying the standard matter effect. We show that if, in addition, C P violation is maximal then this gives rise to an exact intrinsic hierarchy degeneracy in the appearance channel, irrespective of the baseline and energy. Introduction of the off diagonal NSI parameter, ɛe τ, shifts the position of this degeneracy to a different ɛe e. Moreover the unknown magnitude and phases of the off diagonal NSI parameters can give rise to additional degeneracies. Overall, given the current model independent limits on NSI parameters, the hierarchy sensitivity of DUNE can get seriously impacted. However, a more precise knowledge of the NSI parameters, especially ɛe e, can give rise to an improved sensitivity. Alternatively, if a NSI exists in nature, and still DUNE shows hierarchy sensitivity, certain ranges of the NSI parameters can be excluded. Additionally, we briefly discuss the implications of ɛe e=-1 (in the Earth) on the Mikheyev-Smirnov-Wolfenstein effect in the Sun.

"The right help at the right time": Positive constructions of peer and professional support for breastfeeding.

PubMed

Burns, Elaine; Schmied, Virginia

2017-10-01

Support during the early establishment phase of breastfeeding is important but women report that health professionals can undermine their confidence with breastfeeding. Breastfeeding support provided in fragmented hospital based models of care predominantly reflect authoritative expert advice-giving which women describe as conflicting and unsupportive. Women show a preference for support from a known midwife, or a peer supporter, or a combination of the two. Peer support counsellors and privately practicing midwives approached breastfeeding support in a similar way. They interacted with women as a ‘knowledgeable friend’ and normalised breastfeeding challenges which enhanced women’s confidence with breastfeeding.

Vascular plant abundance and diversity in an alpine heath under observed and simulated global change

PubMed Central

Alatalo, Juha M.; Little, Chelsea J.; Jägerbrand, Annika K.; Molau, Ulf

2015-01-01

Global change is predicted to cause shifts in species distributions and biodiversity in arctic tundra. We applied factorial warming and nutrient manipulation to a nutrient and species poor alpine/arctic heath community for seven years. Vascular plant abundance in control plots increased by 31%. There were also notable changes in cover in the nutrient and combined nutrient and warming treatments, with deciduous and evergreen shrubs declining, grasses overgrowing these plots. Sedge abundance initially increased significantly with nutrient amendment and then declined, going below initial values in the combined nutrient and warming treatment. Nutrient addition resulted in a change in dominance hierarchy from deciduous shrubs to grasses. We found significant declines in vascular plant diversity and evenness in the warming treatment and a decline in diversity in the combined warming and nutrient addition treatment, while nutrient addition caused a decline in species richness. The results give some experimental support that species poor plant communities with low diversity may be more vulnerable to loss of species diversity than communities with higher initial diversity. The projected increase in nutrient deposition and warming may therefore have negative impacts on ecosystem processes, functioning and services due to loss of species diversity in an already impoverished environment.

Barbara's story: a thematic analysis of a relative's reflection of being in the intensive care unit.

PubMed

Christensen, Martin; Probst, Barbara

2015-03-01

The aim of this reflective account is to provide a view of the intensive care unit (ICU) relative's experiences of supporting and being supported in the ICU. Understanding the relatives' experiences of ICU is important especially because a recent work has identified the potential for this group to develop post-traumatic stress disorder, a condition that is normally equated with the ICU survivor. A thematic analysis was used in identifying emerging themes that would be significant in an ICU nursing context. The incident took place in two 8-bedded ICUs (Private and National Health Service) in October. Two emergent themes were identified from the reflective story - fear of the technological environment and feeling hopeless and helpless. The use of relative stories as an insight into the live experiences of ICU relatives may give a deeper understanding of their life-world. The loneliness, anguish and pain of the ICU relative extends beyond the walls of the ICU, and this is often negated as the focus of the ICU team is the patient. Developing strategies to support relatives might include the use of relative diaries used concurrently with patient diaries to support this groups recovery or at the very least a gaining a sense of understanding for their ICU experience. Relative follow-up clinics designed specifically to meet their needs where support and advice can be given by the ICU team, in addition to making timely and appropriate referrals to counselling services and perhaps involving spiritual leaders where appropriate. © 2014 British Association of Critical Care Nurses.

The extraterrestrial Lyman-alpha emission was mapped by the OGO 5 satellite, when it was outside the geocorona. Three maps, obtained at different periods of the year, are presented and analyzed. The results suggest that at least half of the emission takes place in the solar system, and give strong support to the theory that in its motion toward the apex, the sun crosses neutral atomic hydrogen of interstellar origin, giving rise to an apparent interstellar wind.

2018-01-01

The objective of this study is to design biomimetic organically modified montmorillonite clay (OMMT) supported chitosan/hydroxyapatite-zinc oxide (CTS/HAP-ZnO) nanocomposites (ZnCMH I-III) with improved mechanical and biological properties compared to previously reported CTS/OMMT/HAP composite. Fourier transform infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy were used to analyze the composition and surface morphology of the prepared nanocomposites. Strong antibacterial properties against both Gram-positive and Gram-negative bacterial strains were established for ZnCMH I-III. pH and blood compatibility study revealed that ZnCMH I-III should be nontoxic to the human body. Cytocompatibility of these nanocomposites with human osteoblastic MG-63 cells was also established. Experimental findings suggest that addition of 5wt% of OMMT into CTS/HAP-ZnO (ZnCMH I) gives the best mechanical strength and water absorption capacity. Addition of 0.1wt% of ZnO nanoparticles into CTS-OMMT-HAP significantly enhanced the tensile strengths of ZnCMH I-III compared to previously reported CTS-OMMT-HAP composite. In absence of OMMT, control sample (ZnCH) also showed reduced tensile strength, antibacterial effect and cytocompatibility with osteoblastic cell compared to ZnCMH I. Considering all of the above-mentioned studies, it can be proposed that ZnCMH I nanocomposite has a great potential to be applied in bone tissue engineering. Copyright © 2017 Elsevier B.V.

How Well Was the Sun Observed during the Maunder Minimum?

NASA Astrophysics Data System (ADS)

Hoyt, Douglas V.; Schatten, Kenneth H.

1996-04-01

In this paper we examine how well the Sun and sunspots were observed during the Maunder Minimum from 1645 to 1715. Recent research has given us the dates of observations by Hevelius, Picard, La Hire, Flamsteed, and about 70 other observers. These specific observations allow a ‘lower estimate’ of the fraction of the time the Sun was observed to be deduced. It is found that 52.7% of the days have recorded observations. There are additional 12 observers who provide general statements that no sunspots were observed during specific years or intervals despite diligent efforts. Taking these statements to mean, unrealistically, that every day during these intervals was observed, gives an ‘upper estimate’ of 98% of the days. If the general statements are relaxed by assuming that 100 ± 50 days per year were actually observed by these diligent observers, than our ‘best estimate’ is that 68%±7% of the days during the Maunder Minimum were observed. In short, this supports the view that the Maunder Minimum existed and was not an artifact of few observations. Some sunspots are probably still missed in modern compilations, but the existence of a prolonged sunspot minimum would not be threatened by their discovery in future research. Additional support for intense scrutiny of the Sun comes from a report of a white-light flare in 1705 and from the numerous reports of new sunspots entering the disk of the Sun.

Shared decision-making and patient autonomy.

PubMed

Sandman, Lars; Munthe, Christian

2009-01-01

In patient-centred care, shared decision-making is advocated as the preferred form of medical decision-making. Shared decision-making is supported with reference to patient autonomy without abandoning the patient or giving up the possibility of influencing how the patient is benefited. It is, however, not transparent how shared decision-making is related to autonomy and, in effect, what support autonomy can give shared decision-making. In the article, different forms of shared decision-making are analysed in relation to five different aspects of autonomy: (1) self-realisation; (2) preference satisfaction; (3) self-direction; (4) binary autonomy of the person; (5) gradual autonomy of the person. It is argued that both individually and jointly these aspects will support the models called shared rational deliberative patient choice and joint decision as the preferred versions from an autonomy perspective. Acknowledging that both of these models may fail, the professionally driven best interest compromise model is held out as a satisfactory second-best choice.

The association between cognitive impairment and community service use patterns in older people living in Australia.

PubMed

Vecchio, Nerina; Fitzgerald, Janna A; Radford, Katrina; Fisher, Ron

2016-05-01

Family plays a vital role in supporting individuals with dementia to reside in the community, thus delaying institutionalisation. Existing research indicates that the burden of care-giving is particularly high for those caring for a person with dementia. Yet, little is known about the uptake of community services by people with a diagnosis of dementia. Therefore, this study aims to better understand the relationship between cognitive impairment and the receipt of community care services. In order to examine the relationship, secondary data collected across Queensland, Australia, from 59,352 home-care clients aged 65 and over during 2007-2008 are analysed. This cross-sectional study uses regression analyses to estimate the relationship between cognitive impairment and service mix, while controlling for socio-demographic characteristics. The dependent variables include formal services, informal care and total home-care service hours during a 12-month period. The findings of this study demonstrate that cognitive impairment is associated with accessing more hours of respite and day centre care but fewer hours of other formal care services. Additionally, the likelihood of support from an informal caregiver increases when a client becomes cognitively impaired. Therefore, this study demonstrates that there is an increased need for respite programmes to support informal caregivers in the future, as the population of people living with dementia increases. These findings support the need for investigations of new and innovative respite models in the future. © 2015 John Wiley & Sons Ltd.

Exploring the breast cancer patient journey: do breast cancer survivors need menopause management support?

Breast cancer survivors can be expected to suffer from menopause symptoms with estrogen deprivation due to cancer treatments, in addition to natural menopause-related estrogen loss. To gain an understanding of what support breast cancer patients have when they suffer from menopausal symptoms, and utilize findings to further inform National Health Service (NHS) care provision for breast cancer survivors. Qualitative study with focus group sessions targeting Caucasian and Asian women with breast cancer. Patient stories, with women describing their breast cancer journey and speaking about support received for any menopausal symptoms. Thematic data analysis of transcription. Breast cancer patients were not sure if they had menopausal symptoms or whether this was due to their breast cancer condition or treatment. Patients had an attitude of acceptance of menopausal symptoms and reported trying to cope with these by themselves. This research identifies a need for more information that is culturally sensitive on managing menopause symptoms, both as side-effects of breast cancer treatments as well as for affect on quality of life during the survivorship phase. Our work also gives insight into cultural remedies used for hot flushes by Asian patients, which they consider as 'cooling' foods. Breast cancer patients want to know whether side-effects of cancer treatment persist long term and how these can be managed. There is a need for improved patient support within any new NHS service models that are developed along breast cancer patient pathways, and inclusion of personalized advice for menopause symptoms.

[Experiences and needs of parents of hospitalised children with disabilities and the health professionals responsible for the child’s health-care – A systematic review].

Children with disabilities are more often hospitalized than healthy children and burden their parents additionally. Though the parents usually take care of the disabled child in the hospital, systematic knowledge on the experiences of these care-giving parents in hospital is missing in German-speaking countries. What are the experiences and needs described by parents of hospitalized children with disabilities as well as by health professionals responsible for the child’s health-care and what are the implications for parental support? A systematic review according to the PRISMA Statement was performed in the databases Pubmed/Medline, PsycINFO, CINAHL and EMBASE in January 2014. Fourteen publications were analysed thematically using content analysis. The literature identified confirmed the heightened burden of the parents and particularly of the nurses due to emotional and work-related stress. Moreover, the adjustment process, mainly of parents of frequently hospitalized children, was detected. Communication and organisation based on family-centred service can improve the parents’ and the child’s wellbeing. Considering the burden experienced by parents, their support must be of central concern for all health professionals. Nurses can support parents and thus the hospitalized child in the adjustment process by focused preparation and continuous attendance based on family-centred care. The latter must be supported by the management and the multidisciplinary team to tailor the competences and the organization accordingly.

The aim of the present study was to investigate whether psycho-social variables, for example social support and task- and emotion-oriented coping would predict psychological and physical well being among young adults with diabetes. Participants were 56 individuals in their twenties suffering from type 1 diabetes. Response rate was 78%. The participants came from the whole of Iceland, 64.3% from the Greater Reykjavík area and 33.9% from rural areas. One participant did not indicate his place of residence. Self-assessment scales were used to assess depression, anxiety, task-, avoidance- and emotion-oriented coping, social support and problems relating to diabetes. Additional information was obtained from patients' records concerning the results of blood glucose measurements (HbA1c). Good social support was related to less anxiety and depression and to less self-reported problems related to having diabetes. Emotion-oriented coping was related to not feeling well and task- oriented coping to feeling better. No relationship was found between psychosocial variables and blood glucose measurements and a limited relationship between self-reported problems related to having diabetes and these measurements. Social support and coping are strongly related to measurements of depression, anxiety and problems related to having diabetes in the present age group. The results indicate that it is very important to teach and strengthen usage, as possible, of task-oriented coping instead of emotion-oriented coping. The results also indicate that social support is highly important for young adults with diabetes type 1. It is clear that friends and family have to be more involved in the treatment and also more educated about the disease and the importance of giving the right kind of support.

Play is an essential part of children's lives. Children with physical disabilities experience difficulties in play, especially those with severe physical disabilities. With the progress of innovative technology, the possibilities to support play are increasing. The purpose of this literature study is to gain insight into the aims, control options and commercial availability of information and communication technology (ICT) and robots to support play (especially play for the sake of play) in children with severe physical disabilities. A systematic literature search in the databases PubMed, CINAHL, IEEE and ERIC was carried out. Titles and abstracts were assessed independently by three reviewers. In addition, studies were selected using Google Scholar, conference proceedings and reference lists. Three main groups of technology for play could be distinguished: robots (n = 8), virtual reality systems (n = 15) and computer systems (n = 4). Besides, ICT and robots developed for specific therapy or educational goals using play-like activities, five of the in total 27 technologies in this study described the aim of "play for play's sake". Many ICT systems and robots to support play in children with physical disabilities were found. Numerous technologies use play-like activities to achieve therapeutic or educational goals. Robots especially are used for "play for play's sake". Implications for Rehabilitation This study gives insight into the aims, control options and commercial availability for application of robots and ICT to support play in children with severe physical disabilities. This overview can be used in both the fields of rehabilitation and special education to search for new innovative intervention options and it can stimulate them to use these innovative play materials. Especially robots may have great potential in supporting "play for play's sake".

Evidence supports music-based oncologic support interventions including music therapy. By comparison, little is understood about music-based self-care. This meta-ethnography examined five published qualitative studies to extend understanding of music's relevance, including helpfulness, for people affected by cancer; including children, adolescents, and adults with cancer, carers, and the bereaved. To improve understanding of music's broad relevance for those affected by cancer. Meta-ethnography strategies informed the analysis. Five studies were synthesized that included 138 participants: 26 children and 28 parents of children with cancer; 12 adolescents and young adults with cancer; 52 adults with cancer; 12 carers; and 8 bereaved. Studies' category and thematic findings were compared and integrated into third-order interpretations, and a line of argument. Perspectives from the five studies that illuminated the line of argument were developed. Music usage can remain incidental, continue normally, and/or change because of cancer's harsh effects. Music can be a lifeline, support biopsychosocial and spiritual well-being, or become elusive, that is, difficult to experience. Music helps or intrudes because it extends self-awareness and social connections, and prompts play, memories, imageries, and legacies. Music therapists may help patients and carers to recover or extend music's helpful effects. Cancer care can be improved through offering music-based resources/services, which give cancer patients and carers opportunities to extend music usage for personal support and, for carers, to support patients. Music therapists can advocate for such resources and educate health professionals about assessing/recognizing when patients' and carers' changed music behaviors signify additional support needs. © the American Music Therapy Association 2016.

Some universities are looking to provide a more diverse range of clinical learning experiences through extended clinical placement programs. This approach will potentially have a significant impact on practitioners. The aim of this study was to conduct a national survey of optometrists to ascertain their perspectives on participating in extended clinical placement programs. Members of Optometry Australia were invited to participate in a survey conducted during June and July 2014. A total of 268 practitioners participated (six per cent of registered Australian optometrists): 159 were predominantly employees or locums and 109 were owners or managers who identified as the key representative of a practice or organisation for the purpose of this survey. Almost two-thirds (65 per cent) of participants, who were employees or locums were supportive of extended clinical placement programs. Among this group, females were more likely to be supportive than males (p = 0.033). In comparison, just over one-third (34 per cent) of participants who were key decision-makers were supportive, with 30 per cent possibly supportive and 36 per cent not supportive. Among key decision-makers, males were more likely to be supportive (p = 0.009). The top three perceived advantages of supervising a student were: opportunity to mentor early career development, opportunity to give back to the profession and future recruitment. The top three perceived disadvantages were: burden on time, decrease in number of patients examined and burden on support staff. Suggested incentives for supervising students were credit for continuing professional development and financial remuneration. There appears to be moderate support for extended clinical placement programs; however, there are incentives that might engage a larger proportion of the profession in the future. These findings can inform the development of effective and sustainable clinical training programs for optometry students. Additionally, the findings might be used as evidence to seek Government support for clinical placement training in optometry. © 2016 Optometry Australia.

Cultural variables are implicated in gambling literature as playing an important role in the initiation and maintenance of gambling activity, however there remains a paucity of research that defines and investigates the association between cultural factors, gambling and problem gambling amongst different cultural groups. The first data collection point for a cohort of mothers within the longitudinal Pacific Islands Families study identified that the Pacific cultural practice of traditional gift-giving was associated with gambling activity and expenditure. In this paper, data about traditional gift-giving and gambling are presented from the third collection point within this study. The results support an association between gambling (rather than problem gambling) and traditional gift-giving. This paper contends the need to contextualise Pacific peoples gambling within Pacific cultures. Also a need is identified to examine and address the psycho-social and cultural impacts of gambling for Pacific peoples.

Thinkers and feelers: Emotion and giving.

PubMed

Corcoran, Katie E

2015-07-01

Voluntary organizations, such as religious congregations, ask their members to contribute money as a part of membership and rely on these contributions for their survival. Yet often only a small cadre of members provides the majority of the contributions. Past research on congregational giving focuses on cognitive rational processes, generally neglecting the role of emotion. Extending Collins' (2004) interaction ritual theory, I predict that individuals who experience positive emotions during religious services will be more likely to give a higher proportion of their income to their congregation than those who do not. Moreover, I argue that this effect will be amplified in congregational contexts characterized by high aggregate levels of positive emotion, strictness, dense congregational networks, and expressive rituals. Using data from the 2001 U.S. Congregational Life Survey and multilevel modeling, I find support for several of these hypotheses. The findings suggest that both cognitive and emotional processes underlie congregational giving. Copyright © 2014 Elsevier Inc. All rights reserved.

HIV/AIDS, a chronic burden in Ghana, poses social and health outcome concerns to those infected. Examining the Medical Outcome Study Social Support Survey (MOS-SSS) instrument among 300 Ghanaians from a cross-sectional design, Principal Component Analysis yielded four factors (positive interaction, trust building, information giving, and essential support), which accounted for 85.73% of the total variance in the MOS-SSS. A logistic regression analysis showed that essential support was the strongest predictor of the length of time an individual stayed in the support group, whereas positive interaction indicated negative association. The study's implications for policy, research, and practice were discussed.

Strategies for the synthesis of supported gold palladium nanoparticles with controlled morphology and composition.

PubMed

Hutchings, Graham J; Kiely, Christopher J

2013-08-20

The discovery that supported gold nanoparticles are exceptionally effective catalysts for redox reactions has led to an explosion of interest in gold nanoparticles. In addition, incorporating a second metal as an alloy with gold can enhance the catalyst performance even more. The addition of small amounts of gold to palladium, in particular, and vice versa significantly enhances the activity of supported gold-palladium nanoparticles as redox catalysts through what researchers believe is an electronic effect. In this Account, we describe and discuss methodologies for the synthesis of supported gold-palladium nanoparticles and their use as heterogeneous catalysts. In general, three key challenges need to be addressed in the synthesis of bimetallic nanoparticles: (i) control of the particle morphology, (ii) control of the particle size distribution, and (iii) control of the nanoparticle composition. We describe three methodologies to address these challenges. First, we discuss the relatively simple method of coimpregnation. Impregnation allows control of particle morphology during alloy formation but does not control the particle compositions or the particle size distribution. Even so, we contend that this method is the best preparation method in the catalyst discovery phase of any project, since it permits the investigation of many different catalyst structures in one experiment, which may aid the identification of new catalysts. A second approach, sol-immobilization, allows enhanced control of the particle size distribution and the particle morphology, but control of the composition of individual nanoparticles is not possible. Finally, a modified impregnation method can allow the control of all three of these crucial parameters. We discuss the effect of the different methodologies on three redox reactions: benzyl alcohol oxidation, toluene oxidation, and the direct synthesis of hydrogen peroxide. We show that the coimpregnation method provides the best reaction selectivity for benzyl alcohol oxidation and the direct synthesis of hydrogen peroxide. However, because of the reaction mechanism, the sol-immobilzation method gives very active and selective catalysts for toluene oxidation. We discuss the possible nature of the preferred active structures of the supported nanoparticles for these reactions. This paper is based on the IACS Heinz Heinemann Award Lecture entitled "Catalysis using gold nanoparticles" which was given in Munich in July 2012.

Universal modal radiation laws for all thermal emitters

PubMed Central

Zhu, Linxiao; Fan, Shanhui

2017-01-01

We derive four laws relating the absorptivity and emissivity of thermal emitters. Unlike the original Kirchhoff radiation law derivations, these derivations include diffraction, and so are valid also for small objects, and can also cover nonreciprocal objects. The proofs exploit two recent approaches. First, we express all fields in terms of the mode-converter basis sets of beams; these sets, which can be uniquely established for any linear optical object, give orthogonal input beams that are coupled one-by-one to orthogonal output beams. Second, we consider thought experiments using universal linear optical machines, which allow us to couple appropriate beams and black bodies. Two of these laws can be regarded as rigorous extensions of previously known laws: One gives a modal version of a radiation law for reciprocal objects—the absorptivity of any input beam equals the emissivity into the “backward” (i.e., phase-conjugated) version of that beam; another gives the overall equality of the sums of the emissivities and the absorptivities for any object, including nonreciprocal ones. The other two laws, valid for reciprocal and nonreciprocal objects, are quite different from previous relations. One shows universal equivalence of the absorptivity of each mode-converter input beam and the emissivity into its corresponding scattered output beam. The other gives unexpected equivalences of absorptivity and emissivity for broad classes of beams. Additionally, we prove these orthogonal mode-converter sets of input and output beams are the ones that maximize absorptivities and emissivities, respectively, giving these beams surprising additional physical meaning.

Development in high-grade dual phase steels with low C and Si design

Zhu, Guo-hui; Zhang, Xue-hui; Mao, Wei-min

2009-12-01

Cold rolled dual phase steels with low C and Si addition were investigated in terms of combination of composition and processing in order to improve mechanical properties and workability including welding and galvanizing. Mo and Cr could be used as alloying elements to partially replace C and Si to assure enough hardening ability of the steels and also give solute-hardening. Mo addition is more effective than Cr addition in terms of obtaining the required volume fraction of martensite and mechanical strength. The ferrite grain was effectively refined by addition of Nb microalloying, which gives optimized mechanical properties. The experimental results show that it is possible to obtain the required mechanical properties of high grade 800 MPa dual phase steel, i.e., tensile strength > 780 MPa, elongation > 15%, and yield/tensile strength ratio < 0.6 in the condition of low carbon (C < 0.11 wt.%) and low silicon design (Si < 0.05 wt.%) through adequate combination of composition and processing.

Daysy is a fertility monitor that uses the fertility awareness method by tracking and analyzing the individual menstrual cycle. In addition, Daysy can be connected to the application DaysyView to transfer stored personal data from Daysy to a smartphone or tablet (IOS, Android). This combination is interesting because as it is shown in various studies, the use of apps is increasing patients´ focus on their disease or their health behavior. The aim of this study was to investigate if by the additional use of an App and thereby improved usability of the medical device, it is possible to enhance the typical-use related as well as the method-related pregnancy rates. In the resultant group of 125 women (2076 cycles in total), 2 women indicated that they had been unintentionally pregnant during the use of the device, giving a typical-use related Pearl-Index of 1.3. Counting only the pregnancies which occurred as a result of unprotected intercourse during the infertile (green) phase, we found 1 pregnancy, giving a method-related Pearl-Index of 0.6. Calculating the pregnancy rate resulting from continuous use and unprotected intercourse exclusively on green days, gives a perfect-use Pearl-Index of 0.8. It seems that combining a specific biosensor-embedded device (Daysy), which gives the method a very high repeatable accuracy, and a mobile application (DaysyView) which leads to higher user engagement, results in higher overall usability of the method.

2016-05-29

Acute myelogenous leukemia is a heterogeneous disease. Recent molecular mutational analysis techniques have shed more light on different, genetically well characterised types of the disease. Treatment approach is uniform except for acute promyelocytic leukemia. Application of the "3 + 7" induction treatment has been the gold standard in the past 40 years. While the dose of cytarabine has not been changed, escalating daunorubicine dose in younger (<60 years) patients with good performance status to 90 mg/m(2) had a positive impact on overall survival. High dose chemotherapy is tolerated poorly in patients older than 60 years of age and, as treatment is not curative in the elderly, improvement of overall survival and quality of life remains the main goal of management in these patients. Low intensity treatment is beneficial and can provide additional advantage over supportive care. Innovative and targeted therapy approaches might give promise to better management of patients with acute myelogenous leukemia.

Objective: to identify and classify the most important occupational stressors affecting nursing professionals in the medical units within a hospital. Method: quantitative-qualitative, descriptive and prospective study performed with Delphi technique in the medical units of a general university hospital, with a sample of 30 nursing professionals. Results: the stressors were work overload, frequent interruptions in the accomplishment of their tasks, night working, simultaneity of performing different tasks, not having enough time to give emotional support to the patient or lack of time for some patients who need it, among others. Conclusion: the most consensual stressors were ranked as work overload, frequent interruptions in the accomplishment of their tasks, night working and, finally, simultaneity of performing different tasks. These results can be used as a tool in the clinical management of hospital units, aiming to improve the quality of life of nursing professionals, organizational models and, in addition, continuous improvement in clinical treatment.

KENNEDY SPACE CENTER, FLA. -- At Launch Pad 39A, a team of external tank specialists from Lockheed Martin and the United Space Alliance undertakes the task of removing the hydrogen feed-through connector in support of space shuttle Atlantis' STS-122 mission. Here, a technician gives the connector a cleaning, removing any residual foam insulation, and begins disconnecting the connector assembly. Some of the tank's engine cutoff sensors, or ECO sensors, failed during propellant tanking for launch attempts on Dec. 6 and Dec. 9. Results of a tanking test on Dec. 18 pointed to an open circuit in the feed-through connector wiring, which is located at the base of the tank. The feed-through connector passes the wires from the inside of the tank to the outside. After the data from additional testing on the connector is analyzed, shuttle program managers will decide on a forward plan. Launch of STS-122 is targeted for January 2008.

Best Practices in Management of Postpartum Pain.

PubMed

Fahey, Jenifer O

Pain has been documented as a major concern for women in the postpartum period. Management of postpartum pain, however, is a relatively neglected area of clinical research. As a result, evidence to support interventions to alleviate the discomforts associated with childbirth is sparse. This paucity of research on postpartum pain management is particularly surprising given that in the United States alone nearly 4 million women give birth each year. Inadequate pain relief in the hours to months following childbirth can interfere with maternal-newborn bonding and feeding and, by impeding mobility, can increase the risk of postpartum complications. In addition, pain that is not adequately managed may increase the risk of chronic pain that lasts beyond the postpartum period. In this article, the more common causes of pain following childbirth are reviewed and recommendations for pain management based on available evidence are outlined. Considerations for pain management in lactating women and for hospital discharge are discussed.

Papua New Guinea (PNG) is undertaking intensified efforts to control malaria. The National Malaria Control Program aims to reduce the burden of disease by large-scale distribution of insecticide-treated bednets, improved diagnosis and implementation of new treatments. A scientific program monitoring the effect of these interventions, including molecular epidemiology studies, closely accompanies the program. Laboratory assays have been developed in (or transferred to) PNG to measure prevalence of infection and intensity of transmission as well as potential resistance to currently used drugs. These assays help to assess the impact of the National Malaria Control Program, and they reveal a much clearer picture of malaria epidemiology in PNG. In addition, analysis of the geographical clustering of parasites aids in selecting areas where intensified control will be most successful. This paper gives an overview of current research and recently completed studies in the molecular epidemiology of malaria conducted in Papua New Guinea.

A recent study has implicated the nucleus accumbens of the ventral striatum in explaining why online-users spend time on the social network platform Facebook. Here, higher activity of the nucleus accumbens was associated with gaining reputation on social media. In the present study, we touched a related research field. We recorded the actual Facebook usage of N=62 participants on their smartphones over the course of five weeks and correlated summary measures of Facebook use with gray matter volume of the nucleus accumbens. It appeared, that in particular higher daily frequency of checking Facebook on the smartphone was robustly linked with smaller gray matter volumes of the nucleus accumbens. The present study gives additional support for the rewarding aspects of Facebook usage. Moreover, it shows the feasibility to include real life behavior variables in human neuroscientific research.

Efforts have been initiated, and are presently being continued, for real-time flight coverage visualizations using the data streams from the X-33 vehicle flights. The flight visualizations that have resulted thus far give convincing support to the expectation that the flights of the X-33 will be exciting and significant space flight milestones... flights of this nation's one-half scale predecessor to its first single-stage-to-orbit, fully-reusable launch vehicle system.

Exposure to diesel exhaust (DE) from vehicles and industry is hazardous and affects proper function of organ systems. DE can interfere with normal physiology after acute and chronic exposure to particulate matter (PM). Exposure leads to potential systemic disease processes in the central nervous, visual, hematopoietic, respiratory, cardiovascular, and renal systems. In this review, we give an overview of the epidemiological evidence supporting the harmful effects of diesel exhaust, and the numerous animal studies conducted to investigate the specific pathophysiological mechanisms behind DE exposure. Additionally, this review includes a summary of studies that used biomarkers as an indication of biological plausibility, and also studies evaluating new technology diesel exhaust (NTDE) and its systemic effects. Lastly, this review includes new approaches to improving DE emissions, and emphasizes the importance of ongoing study in this field of environmental health. Copyright © 2018 Elsevier Ltd.

A Review on Radio-Over-Fiber Technology-Based Integrated (Optical/Wireless) Networks

NASA Astrophysics Data System (ADS)

Rajpal, Shivika; Goyal, Rakesh

2017-06-01

In the present paper, radio-over-fiber (RoF) technology has been proposed, which is the integration of the optical and radio networks. With a high transmission capacity, comparatively low cost and low attenuation, optical fiber provides an ideal solution for accomplishing the interconnections. In addition, a radio system enables the significant mobility, flexibility and easy access. Therefore, the system integration can meet the increasing demands of subscribers for voice, data and multimedia services that require the access network to support high data rates at any time and any place inexpensively. RoF has the potentiality to the backbone of the wireless access network and it has gained significant momentum in the last decade as a potential last-mile access scheme. This paper gives the comprehensive review of RoF technology used in the communication system. Concept, applications, advantages and limitations of RoF technology are also discussed in this paper.

Articular cartilage guarantees for an optimal functioning of diarthrodial joints by providing a gliding surface for smooth articulation, weight distribution, and shock absorbing while the subchondral bone plays a crucial role in its biomechanical and nutritive support. Both tissues together form the osteochondral unit. The structural assessment of the osteochondral unit is now considered the key standard procedure for evaluating articular cartilage repair in translational animal models. The aim of this review is to give a detailed overview of the different methods for a comprehensive evaluation of osteochondral repair. The main focus is on the histological assessment as the gold standard, together with immunohistochemistry, and polarized light microscopy. Additionally, standards of macroscopic, non-destructive imaging such as high resolution MRI and micro-CT, biochemical, and molecular biological evaluations are addressed. Potential pitfalls of analysis are outlined. A second focus is to suggest recommendations for osteochondral evaluation. Copyright © 2015 Elsevier GmbH. All rights reserved.

Metaphors, stigma and the 'Alzheimerization' of the euthanasia debate.

PubMed

Johnstone, Megan-Jane

2013-07-01

This paper reports the findings of an unobtrusive research inquiry investigating the possible use and misuse of Alzheimer's disease in public policy debate on the legalization of euthanasia. The component of the study being reported identified the problematic use of five key metaphors: the Alzheimer metaphor, which in turn was reinforced by three additional metaphors--the epidemic metaphor, the military metaphor, and the predatory thief metaphor; and the euthanasia metaphor. All metaphors were found to be morally loaded and used influentially to stigmatize Alzheimer's disease and mediate public opinion supporting the legalization of euthanasia as an end-of-life 'solution' for people with the disease. It is contended that, in the interests of promoting intellectual honesty and giving proper recognition to the extraordinary complexity of the issue, the problematic use and influence of metaphoric thinking in the public debate about Alzheimer's disease and euthanasia needs to be made transparent, questioned and challenged.

Thermodynamic data are needed for all kinds of simulations of materials processes. Thermodynamics determines the set of stable phases and also provides chemical potentials, compositions and driving forces for nucleation of new phases and phase transformations. Software to simulate materials properties needs accurate and consistent thermodynamic data to predict metastable states that occur during phase transformations. Due to long calculation times thermodynamic data are frequently pre-calculated into "lookup tables" to speed up calculations. This creates additional uncertainties as data must be interpolated or extrapolated and conditions may differ from those assumed for creating the lookup table. Speed and accuracy requires that thermodynamic software is fully parallelized and the Open-Calphad (OC) software is the first thermodynamic software supporting this feature. This paper gives a brief introduction to computational thermodynamics and introduces the basic features of the OC software and presents four different application examples to demonstrate its versatility.

2011-08-05

Immobilized metal affinity monolith column as a new class of chromatographic support is shown to be superior to conventional particle-based column as plasmid DNA (pDNA) purification platform. By harnessing the affinity of endotoxin to copper ions in the solution, a majority of endotoxin (90%) was removed from the alkaline cell lysate using CuCl(2)-induced precipitation. RNA and remaining endotoxin were subsequently removed to below detection limit with minimal loss of pDNA using either monolith or particle-based column. Monolith column has the additional advantage of feed concentration and flowrate-independent dynamic binding capacity for RNA molecules, enabling purification process to be conducted at high feed RNA concentration and flowrate. The use of monolith column gives three fold increased productivity of pDNA as compared to particle-based column, providing a more rapid and economical platform for pDNA purification.

Farmer, Cristan A; Aman, Michael G

2009-01-01

Whereas some scales exist for assessing aggression in typically developing children, they do not give a detailed analysis, and none is available for populations with developmental disabilities (DD). Parents of 365 children with DD completed the Children's Scale of Hostility and Aggression: Reactive/Proactive (C-SHARP), which surveys the severity of aggressive and hostile behaviors (Problem Scale) in addition to their proactive or reactive qualities (the Provocation Scale). Factor analysis yielded a 5-factor solution: I. Verbal Aggression (12 items), II. Bullying (12 items), III. Covert Aggression (11 items), IV. Hostility (9 items), and V. Physical Aggression (8 items). Coefficient alpha ranged from moderate (0.74, Physical Aggression) to high (0.92, Verbal Aggression). General validity was supported by expected differences between age and gender groups. Preliminary normative data were presented. The C-SHARP appears to be a promising tool for assessing aggression and hostility in children with DD.

Repurposing doxycycline for synucleinopathies: remodelling of α-synuclein oligomers towards non-toxic parallel beta-sheet structured species

Synucleinophaties are progressive neurodegenerative disorders with no cure to date. An attractive strategy to tackle this problem is repurposing already tested safe drugs against novel targets. In this way, doxycycline prevents neurodegeneration in Parkinson models by modulating neuroinflammation. However, anti-inflammatory therapy per se is insufficient to account for neuroprotection. Herein we characterise novel targets of doxycycline describing the structural background supporting its effectiveness as a neuroprotector at subantibiotic doses. Our results show that doxycycline reshapes α-synuclein oligomers into off-pathway, high-molecular-weight species that do not evolve into fibrils. Off-pathway species present less hydrophobic surface than on-pathway oligomers and display different β-sheet structural arrangement. These structural changes affect the α-synuclein ability to destabilize biological membranes, cell viability, and formation of additional toxic species. Altogether, these mechanisms could act synergically giving novel targets for repurposing this drug. PMID:28155912

The CSCF VAX cluster provides interactive computing for 100 users during prime time, plus a considerable amount of daytime and overnight batch processing. While this cluster represents less than 10% of the VAX computing power at BNL (6 MIPS out of 70), it has served as an important center for this larger network, supporting special hardware and software too expensive to maintain on every machine. In addition, it is the only unrestricted facility available to VAX/VMS users (other machines are typically dedicated to special projects). This committee's analysis shows that the cpu's on the CSCF cluster are currently badly oversaturated,more » frequently giving extremely poor interactive response. Short batch jobs (a necessary part of interactive work) typically take 3 to 4 times as long to execute as they would on an idle machine.

Weak connections form an infinite number of patterns in the brain

2017-04-01

Recently, much attention has been paid to interpreting the mechanisms for memory formation in terms of brain connectivity and dynamics. Within the plethora of collective states a complex network can exhibit, we show that the phenomenon of Collective Almost Synchronisation (CAS), which describes a state with an infinite number of patterns emerging in complex networks for weak coupling strengths, deserves special attention. We show that a simulated neuron network with neurons weakly connected does produce CAS patterns, and additionally produces an output that optimally model experimental electroencephalograph (EEG) signals. This work provides strong evidence that the brain operates locally in a CAS regime, allowing it to have an unlimited number of dynamical patterns, a state that could explain the enormous memory capacity of the brain, and that would give support to the idea that local clusters of neurons are sufficiently decorrelated to independently process information locally.

The need to share gait analysis data to improve clinical decision support has been recognised since the early 1990s. GaitaBase has been established to provide a web-accessible repository system of gait analysis data to improve the sharing of data across local and international clinical and research community. It is used by several clinical and research groups across the world providing cross-group access permissions to retrieve and analyse the data. The system is useful for bench-marking and quality assurance, clinical consultation, and collaborative research. It has the capacity to increase the population sample size and improve the quality of 'normative' gait data. In addition the accumulated stored data may facilitate clinicians in comparing their own gait data with others, and give a valuable insight into how effective specific interventions have been for others. 2009 Elsevier Ltd.

The science community has had success in remote field experiences using two distinctly different models for humans-in-the-loop: the Apollo Science Support team (science backroom), and the robotic exploration of Mars. In the Apollo experience, the science team helped train the crew, designed geologic traverses, and made real-time decisions by reviewing audio and video transmissions and providing recommendations for geologic sampling. In contrast, the Mars Exploration Rover (MER) and Mars Science Lab (MSL) missions have been conducted entirely robotically, with significant time delays between science- driven decisions and remote field activities. Distinctive operations methods and field methodologies were developed for MER/MSL [1,2] because of the reliance on the "backroom" science team (rather than astronaut crew members) to understand the surroundings. Additionally, data are relayed to the team once per day, giving the team many hours or even days to assimilate the data and decide on a plan of action.

Does Consumer Confidence Forecast Household Saving and Borrowing Behavior? Evidence for Poland.

2017-01-01

Consumer confidence plays an important role in households' decision-making processes. This study investigates the effects of consumer confidence on household saving and borrowing behavior that are unsatisfactorily considered in previous discussions. The questions of interest are first, whether indexes of consumer confidence have any predictive power on their own for future household saving and borrowing rates, and second, whether they contain information about future household saving and borrowing rates aside from the information contained in other available indicators. In addition to aggregate confidence indicators, their components are used to provide more precise information. Overall, the multiple linear regression analysis (OLS technique) of Polish time-series data gives positive answers to both questions. This finding supports the recommendation of combining the strengths of objective indicators (such as economic fundamentals) and subjective indicators (such as consumer confidence) to improve household financial behavior forecasts.

Establishing a successful clinical research program.

Clinical research (CR) is a natural corollary to clinical surgery. It gives an investigator the opportunity to critically review their results and develop new strategies. This article covers the critical factors and the important components of a successful CR program. The first and most important step is to build a dedicated research team to overcome time constraints and enable a surgical practice to make CR a priority. With the research team in place, the next step is to create a program on the basis of an original idea and new clinical hypotheses. This often comes from personal experience supported by a review of the available evidence. Randomized controlled (clinical) trials are the most stringent way of determining whether a cause-effect relationship exists between the intervention and the outcome. In the proper setting, translational research may offer additional avenues allowing clinical application of basic science discoveries.

Agency.

Wise, M Norton

2016-12-01

In support of Frans van Lunteren’s project for big-picture history organized around “mediating machines,” these comments stress “mediation” as active agency in the world rather than as mere metaphor, on the view that this active agency underlies the potency of technologies as mediators, both between different domains of knowledge and between theories and things. Similarly important for this power is the diversity of the particular constructions that constitute mediators like “balances” or “engines.” Diversity of meaning and action gives them their cultural reach, from mechanical contrivance to natural process to political ideology. An interesting question remains about how many mediating machines will suffice for the big picture of modernity over four centuries. Statistics, for example, might be a crucial addition. Another question concerns how to characterize the knowledge regime of a mediating machine. Van Lunteren chooses “information” for the computer. He might also have chosen “complexity,” with different import for the character of postmodernity.

Six degree-of-freedom scanning supports and manipulators based on parallel robots

The exploitation of third generation SR sources heavily relies on accurate and stable positioning and scanning of samples and optical elements. In some cases, active feedback is also necessary. Normally, these tasks are carried out by serial addition of individual components, each of them providing a well-defined excursion path. On the contrary, the exploitation of the concept of parallel robots, structures in close cinematic chain, permits us to follow any given trajectory in the six-dimensional space with a large increase in accuracy and stiffness. At ESRF, the parallel robot architecture conceived some tens of years ago for flight simulators has been adapted to both actively align and operate optical elements of considerable weight and position small samples in ultrahigh vacuum. The performance of these devices gives results far superior to the initial specification and a variety of drive mechanisms are being developed to fit the different needs of the ESRF beamlines.

Stalder, Daniel R.

Given indirect indications in sex role and soda! psychology research that mathematical-deductive reasoning may negatively relate to social acuity, Study 1 investigated whether mathematicians were less attributionally complex than nonmathematicians. Study 1 administered the Attributional Complexity Scale, a measure of social acuity, to female and male faculty members and graduate students in four Midwestern schools. Atlrihutional complexity (AC) is the ability and motivation to give complex explanations for behavior. Study 1 found a significant interaction between field and gender. Only among women did mathematicians score lower on AC. In addition, an established gender difference in AC (that women score higher than men) was present only among nonmathematicians. Studies 2 and 3 offered some preliminary support for the possibility that it is generally female students who score tow on AC who aspire to he mathematicians and for the underlying view that female students' perceived similarity to mathematicians can influence their vocational choices.

Chromium: A Stress-Processing Framework for Interactive Rendering on Clusters

We describe Chromium, a system for manipulating streams of graphics API commands on clusters of workstations. Chromium's stream filters can be arranged to create sort-first and sort-last parallel graphics architectures that, in many cases, support the same applications while using only commodity graphics accelerators. In addition, these stream filters can be extended programmatically, allowing the user to customize the stream transformations performed by nodes in a cluster. Because our stream processing mechanism is completely general, any cluster-parallel rendering algorithm can be either implemented on top of or embedded in Chromium. In this paper, we give examples of real-world applications thatmore » use Chromium to achieve good scalability on clusters of workstations, and describe other potential uses of this stream processing technology. By completely abstracting the underlying graphics architecture, network topology, and API command processing semantics, we allow a variety of applications to run in different environments.« less

3D Virtual Environment Used to Support Lighting System Management in a Building

NASA Astrophysics Data System (ADS)

Sampaio, A. Z.; Ferreira, M. M.; Rosário, D. P.

The main aim of the research project, which is in progress at the UTL, is to develop a virtual interactive model as a tool to support decision-making in the planning of construction maintenance and facilities management. The virtual model gives the capacity to allow the user to transmit, visually and interactively, information related to the components of a building, defined as a function of the time variable. In addition, the analysis of solutions for repair work/substitution and inherent cost are predicted, the results being obtained interactively and visualized in the virtual environment itself. The first component of the virtual prototype concerns the management of lamps in a lighting system. It was applied in a study case. The interactive application allows the examination of the physical model, visualizing, for each element modeled in 3D and linked to a database, the corresponding technical information concerned with the use of the material, calculated for different points in time during their life. The control of a lamp stock, the constant updating of lifetime information and the planning of periodical local inspections are attended on the prototype. This is an important mean of cooperation between collaborators involved in the building management.

A recommendation module to help teachers build courses through the Moodle Learning Management System

Limongelli, Carla; Lombardi, Matteo; Marani, Alessandro; Sciarrone, Filippo; Temperini, Marco

2016-01-01

In traditional e-learning, teachers design sets of Learning Objects (LOs) and organize their sequencing; the material implementing the LOs could be either built anew or adopted from elsewhere (e.g. from standard-compliant repositories) and reused. This task is applicable also when the teacher works in a system for personalized e-learning. In this case, the burden actually increases: for instance, the LOs may need adaptation to the system, through additional metadata. This paper presents a module that gives some support to the operations of retrieving, analyzing, and importing LOs from a set of standard Learning Objects Repositories, acting as a recommending system. In particular, it is designed to support the teacher in the phases of (i) retrieval of LOs, through a keyword-based search mechanism applied to the selected repositories; (ii) analysis of the returned LOs, whose information is enriched by a concept of relevance metric, based on both the results of the searching operation and the data related to the previous use of the LOs in the courses managed by the Learning Management System; and (iii) LO importation into the course under construction.

Nearly 60% of American adults and 80% of Internet users have sought health information online. Moreover, Internet users are no longer solely passive consumers of online health content; they are active producers as well. Social media, such as social networking sites, are increasingly being used as online venues for the exchange of health-related information and advice. However, little is known about how participation on health-related social networking sites affects users. Research has shown that women participate more on social networking sites and social networks are more influential among same-sex members. Therefore, this study examined how participation on a social networking site about pregnancy influenced members' health-related attitudes and behaviors. The authors surveyed 114 pregnant members of 8 popular pregnancy-related sites. Analyses revealed that time spent on the sites was less predictive of health-related outcomes than more qualitative assessments such as trust in the sites. Furthermore, providing support was associated with the most outcomes, including seeking more information from additional sources and following recommendations posted on the sites. The implications of these findings, as well as directions for future research, are discussed.

This improvement provides critical support to the impending flyby of Pluto by New Horizons. New Horizons can do inbound navigation of the system to improve its targeting. This navigation is capable of nearly eliminating the sky-plane errors but can do little to constrain the time of closest approach. Thus the focus on this work was to better determine Pluto's heliocentric distance and to determinemore » the uncertainty on that distance with a particular eye to eliminating systematic errors that might have been previously unrecognized.

This new analysis gives us more confidence that these estimations are accurate and are sufficient to support a successful flyby of Pluto by New Horizons.« less

The Roles of Vitamin C in Skin Health

Pullar, Juliet M.; Carr, Anitra C.; Vissers, Margreet C. M.

2017-01-01

The primary function of the skin is to act as a barrier against insults from the environment, and its unique structure reflects this. The skin is composed of two layers: the epidermal outer layer is highly cellular and provides the barrier function, and the inner dermal layer ensures strength and elasticity and gives nutritional support to the epidermis. Normal skin contains high concentrations of vitamin C, which supports important and well-known functions, stimulating collagen synthesis and assisting in antioxidant protection against UV-induced photodamage. This knowledge is often used as a rationale for the addition of vitamin C to topical applications, but the efficacy of such treatment, as opposed to optimising dietary vitamin C intake, is poorly understood. This review discusses the potential roles for vitamin C in skin health and summarises the in vitro and in vivo research to date. We compare the efficacy of nutritional intake of vitamin C versus topical application, identify the areas where lack of evidence limits our understanding of the potential benefits of vitamin C on skin health, and suggest which skin properties are most likely to benefit from improved nutritional vitamin C intake.

Skin is a multifunctional organ with activities in protection, metabolism and regulation. Skin is in a continuous exposure to oxidizing agents and inflammogens from the sun and from the contact with the environment. These agents may overload the skin auto-defense capacity. To strengthen skin defense mechanisms against oxidation and inflammation, supplementation of exogenous antioxidants is a promising strategy. Quercetin is a flavonoid with very pronounced effective antioxidant and antiinflammatory activities, and thus a candidate of first choice for such skin supplementation. Quercetin showed interesting actions in cellular and animal based models, ranging from protecting cells from UV irradiation to support skin regeneration in wound healing. However, due to its poor solubility, quercetin has limited skin penetration ability, and various formulation approaches were taken to increase its dermal penetration. In this article, the quercetin antioxidant and antiinflammatory activities in wound healing and supporting skin against aging are discussed in detail. In addition, quercetin topical formulations from conventional emulsions to novel nanoformulations in terms of skin penetration enhancement are also presented. This article gives a comprehensive review of quercetin for topical application from biological effects to pharmaceutical formulation design for the last 25 years of research.

2017-12-01

Decision support tools that quantitatively estimate the cost and performance of infrastructure alternatives are valuable for urban planners. Such a tool is needed to aid in planning stormwater projects to meet diverse goals such as the regulation of stormwater runoff and its pollutants, minimization of economic costs, and maximization of environmental and social benefits in the communities served by the infrastructure. This work gives a brief overview of an integrated decision support tool, called i-DST, that is currently being developed to serve this need. This presentation focuses on the development of a default database for the i-DST that parameterizes water quality treatment efficiency of stormwater best management practices (BMPs) by region. Parameterizing the i-DST by region will allow the tool to perform accurate simulations in all parts of the United States. A national dataset of BMP performance is analyzed to determine which of a series of candidate regionalizations explains the most variance in the national dataset. The data used in the regionalization analysis comes from the International Stormwater BMP Database and data gleaned from an ongoing systematic review of peer-reviewed and gray literature. In addition to identifying a regionalization scheme for water quality performance parameters in the i-DST, our review process will also provide example methods and protocols for systematic reviews in the field of Earth Science.

The ISF Academy was founded by Charles Kao, a Nobel Prize laureate. In 2011, the Shuyuan programs were established at The ISF Academy to operate both as a "school within a school" and as a "school outside the classroom." The Shuyuan programs work together with the IBO Science and Technology subject areas to develop comprehensive and challenging opportunities that address the 14 Grand Engineering Challenges. The goal is to establish co-curricular programs that go beyond the taught curriculum and support STEM curricula. Several programs outside of the classroom include an onsite robotics researcher, underwater and land based robotics programs, field trips, whole school food waste composting and the implementation of an energy tracking system. Relationships with several local universities allow students to work closely with professors in research settings and, annually, a leading researcher gives a keynote speech to our students. Other signature Shuyuan programs have developed international strategic relationships with the NRI at Cambridge University, where students spend several weeks studying science and civilization in China using primary source materials. Additionally, Shuyuan has supported extension opportunities for classroom teachers with institutional partnerships that include the British Council, governmental organizations, local universities, corporations, and NGOs. In conclusion, the overall goal of the Shuyuan Programs is to provide experiential learning opportunities that challenge conventional curriculum design in a manner that is supportive and innovative!

Nursing students' intentions to use research as a predictor of use one year post graduation: a prospective study.

PubMed

Forsman, Henrietta; Wallin, Lars; Gustavsson, Petter; Rudman, Ann

2012-09-01

Graduating nursing students are expected to have acquired the necessary skills to provide research-based care to patients. However, recent studies have shown that new graduate nurses report their extent of research use as relatively low. Because behavior intention is a well-known predictor of subsequent behavior, this gives reasons to further investigate graduating nursing students' intentions to use research in clinical practice after undergraduate study. To investigate graduating nursing students' intentions to use research in clinical practice and, furthermore, to investigate whether intention in itself and as a mediating variable can predict subsequent research use behavior in clinical practice one year post graduation. A follow-up study was performed of graduating nursing students in their final semester of undergraduate study (2006) and at one year post graduation (2008). Data were collected within the larger national survey LANE (Longitudinal Analysis of Nursing Education). A sample of 1319 respondents was prospectively followed. Graduating nursing students' intentions to use research instrumentally were studied as a predictor of their subsequent instrumental research use one year post graduation. A statistical full mediation model was tested to evaluate the effects of intention and factors from undergraduate study on subsequent research use in daily care. Thirty-four percent of the nursing students intended to use research on more than half or almost every working shift in their future clinical practice. Intention showed a direct effect on research use behavior. In addition, significant indirect effects on research use were shown for capability beliefs (regarding practicing the principles of evidence-based practice) and perceived support for research use (from campus and clinical education), where intention acted as a mediating factor for those effects. Students rated a modest level of intention to use research evidence. Intentions close to graduation acted as an essential predictor of subsequent research use behavior, both through a direct effect and as a mediating variable. These findings give support for designing future interventions aiming at influencing students' intention to use research to improve subsequent behavior. Focusing on strengthening students' capability beliefs and providing support for research use appear as promising target activities. Copyright © 2012 Elsevier Ltd. All rights reserved.

3D Printing, Additive Manufacturing, and Solid Freeform Fabrication: The Technologies of the Past, Present and Future

NASA Astrophysics Data System (ADS)

Beaman, Joseph

2015-03-01

Starting in the late 1980's, several new technologies were created that have the potential to revolutionize manufacturing. These technologies are, for the most part, additive processes that build up parts layer by layer. In addition, the processes that are being touted for hard-core manufacturing are primarily laser or e-beam based processes. This presentation gives a brief history of Additive Manufacturing and gives an assessment for these technologies. These technologies initially grew out of a commercial need for rapid prototyping. This market has a different requirement for process and quality control than traditional manufacturing. The relatively poor process control of the existing commercial Additive Manufacturing equipment is a vestige of this history. This presentation discusses this history and improvements in quality over time. The emphasis will be on Additive Manufacturing processes that are being considered for direct manufacturing, which is a different market than the 3D Printing ``Makerbot'' market. Topics discussed include past and present machine sensors, materials, and operational methods that were used in the past and those that are used today to create manufactured parts. Finally, a discussion of new methods and future directions of AM is presented.

Designation of the anterior/posterior axis in pregastrula Xenopus laevis.

Lane, M C; Sheets, M D

2000-09-01

A new fate map for mesodermal tissues in Xenopus laevis predicted that the prime meridian, which runs from the animal pole to the vegetal pole through the center of Spemann's organizer, is the embryo's anterior midline, not its dorsal midline (M. C. Lane and W. C. Smith, 1999, Development 126, 423-434). In this report, we demonstrate by lineage labeling that the column 1 blastomeres at st. 6, which populate the prime meridian, give rise to the anterior end of the embryo. In addition, we surgically isolate and culture tissue centered on this meridian from early gastrulae. This tissue forms a patterned head with morphologically distinct ventral and dorsal structures. In situ hybridization and immunostaining reveal that the cultured heads contain the anterior tissues of all three germ layers, correctly patterned. Regardless of how we dissect early gastrulae along meridians running from the animal to the vegetal pole, both the formation of head structures and the expression of anterior marker genes always segregate with the prime meridian passing through Spemann's organizer. The prime meridian also gives rise to dorsal, axial mesoderm, but not uniquely, as specification tests show that dorsal mesoderm arises in fragments of the embryo which exclude the prime meridian. These results support the hypothesis that the midline that bisects Spemann's organizer is the embryo's anterior midline. Copyright 2000 Academic Press.

[A Reflection on the Policy of Transcultural Long-Term Care for the Indigenous Peoples in Taiwan].

Subeq, Yi-Maun; Hsu, Mutsu

2016-06-01

Giving high-profile attention to socio-cultural and traditional beliefs in the promotion of long-term care policies enjoys strong, consensus support in the field of transcultural nursing. To protect the rights of indigenous people in Taiwan, the Ministry of Health and Welfare incorporated the concept of cultural care into the Long-term Care Services Act, which was approved by the Legislature in May 2014. However, the policies, resource strategies, manpower allocations, and staff educations and trainings related to this act are still await implementation in indigenous areas. Beyond the concept of professional healthcare, which considers cultural sensitivity, suitability, and ability, cultural care gives greater priority to crossing cultural barriers, integrating with the lifestyle of clients, and addressing their concerns in order to improve the well-being of target populations. The present article reviews current long-term care policy to highlight the importance of considering the cultural needs of the indigenous peoples of Taiwan in order to enhance the efficiency and impact of long-term care programs. Furthermore, the findings strongly recommend that additional resources be provided in order to meet the long-term care needs of indigenous communities. Finally, cultural-specific, long-term care service strategies should be promulgated in order to upgrade well-being in order to ease and comfort the feelings of indigenous people.

The leader's challenge: meetings, spiritual energy, and sneaker ratio.

PubMed

Kerfoot, Karlene

2004-01-01

Leaders who inspire are affirming to everyone in the meeting. They create the environment that meets the needs of the people first, not the leaders. People yearn to be heard, and to be engaged with their soul in genuine dialogue and engagement. If that doesn't happen in the meeting, then they search for meaning and support of their soul elsewhere and sneaker time increases. Leaders get from people what they give to them. If people in a meeting are given nothing, they in turn have nothing to give. If they truly feel they are served by the leader, they will give back much more than they receive. As Martin Luther King, Jr. so aptly said: "Everyone can be great because everyone can serve.

A key part of the transition to parenthood is giving birth and mothers and fathers need to be carefully prepared for this life changing experience. The time generally available for parent education means that it may not be possible or desirable to give detailed information about anatomy and physiology and the management of labour. Instead, the focus in PBB is on helping group members understand what the experience of labour might be like and on helping them maximise their personal resources for coping. Additional information is given in response to individual or group need and parents are signposted to further resources.

A completely non-chromatographic and highly large-scale adaptable synthesis of acrylic polymer beads containing proline and prolineamides has been developed. Novel monomeric proline (meth)acrylates are prepared from hydroxyproline in only one step. Free-radical copolymerization then gives solid-supported proline organocatalysts directly in as little as two steps overall, without using any prefabricated solid supports, by using either droplet or dispersion polymerization. These affordable acrylic beads have highly favorable and adjustable swelling characteristics and are excellent reusable catalysts for organocatalytic reactions.

The preembryo as potential: a reply to John A. Robertson.

1991-12-01

... In conclusion, let me agree with Robertson that reasonable persons may indeed disagree on concrete conclusions touching preembryo freezing, discard, research, and diagnosis. But it is one of the challenges to reasonable people to give reasons for their conclusions. When Robertson notes that preembryo research "has been found acceptable by most bodies that have examined the subject," he leaves unstated the fact that many of these bodies have not given reasons for their conclusions. This is especially true of the Warnock Committee. It is definitely not true of John Robertson. He has attempted to give analytic support for his rather permissive positions. I find this support too fragile for its assigned task, though I hasten to say that this does not mean that only a totally prohibitive position is defensible or is mine. Prima facie still means prima facie.

The experience of labor and birth, referred to as childbirth, is complex, multidimensional, and subjective, relating to both the outcome and the process that is experienced by an individual woman. The aim of this study was to describe the experience of childbirth among Kurdish women giving birth at Besat Hospital in Sanandaj, Iran. A qualitative study was conducted using phenomenological approach. Women eligible for the study were recruited from the postpartum ward. Inclusion criteria were being an Iranian Kurdish woman, being nulliparous, and having vaginal childbirth. Data collection was performed between 2010 and 2011. Women were interviewed by the first researcher 6-12 weeks after they had given birth to their first child. All participants had spontaneous vaginal births without their husbands present. None of them received any analgesia or anesthesia during labor and birth. The findings are described under the following four themes: Feeling empowered, changing life, importance of being supported during labor, and the spiritual dimensions of giving birth. Women communicate through telling stories and create meaning as they articulate their feelings about pivotal life events such as childbirth. The findings of this study provide a useful first step toward the identification of aspects of Kurdish women's experience of giving birth. The women in this study identified that the presence or absence of effective support had a significant effect on their experience of labor and birth. It is important for midwives and other professionals to understand the benefits of support given for women during childbirth.

This article presents the findings of a self-report study of the consequences of being an informal caregiver in Malaysia. The aim of this exploratory study was to examine Malaysian efforts in assisting informal caregivers, based on an analysis of the issues and concerns raised by the caregivers themselves. Data were obtained from a cross-sectional survey of informal caregivers in 2009. This sample comprised parents, spouses and/or adult siblings, and adult children, caring for their children, spouses or siblings and parents who were chronically ill and/or had a disability. Of 300 prospective participants, only 175 could be located (58%), but all those contacted agreed to participate. Respondents were randomly selected and interviewed using a structured questionnaire to identify the emotional, financial, social and physical issues consequent upon being a caregiver. Most respondents reported that their care-giving responsibilities had impacted their emotional, financial, social and/or physical well-being. Inadequate and/or uncertain income was by far the greatest concern followed in descending order by social, physical and emotional consequences. The one-way analysis of variance showed significant differences among the three categories of caregivers with respect to physical and emotional consequences. The findings show that care-giving has detrimental effects on the lives of informal caregivers, and that they are in significant need of social support to help them deal with care-giving tasks and responsibilities. Based on the findings, an integrated social support programme is proposed, tailored to the needs of informal caregivers. © 2013 John Wiley & Sons Ltd.

Versatile molecular tools for creating driving transgenes and other invasive genetic factors present regulatory, ethical, and environmental challenges that should be addressed to ensure their safe use. In this article, we discuss driving transgenes and invasive genetic factors that can potentially spread after their introduction into a small proportion of individuals in a population. The potential of invasive genetic factors to increase their number in natural populations presents challenges that require additional safety measures not provided by previous recommendations regarding accidental release of arthropods. In addition to providing physical containment, invasive genetic factors require greater attention to strain management, including their distribution and identity confirmation. In this study, we focus on insects containing such factors with recommendations for investigators who are creating them, institutional biosafety committees charged with ensuring safety, funding agencies providing support, those managing insectaries handling these materials who are responsible for containment, and other persons who will be receiving insects-transgenic or not-from these facilities. We give specific examples of efforts to modify mosquitoes for mosquito-borne disease control, but similar considerations are relevant to other arthropods that are important to human health, the environment, and agriculture.

Impact of substituents and nonplanarity on nickel and copper porphyrin electrochemistry: first observation of a Cu(II)/Cu(III) reaction in nonaqueous media.

Electrochemical studies of the oxidation of dodecasubstituted and highly nonplanar nickel porphyrins in a noncoordinating solvent have previously revealed the first nickel(III) porphyrin dication. Herein, we investigate if these nonplanar porphyrins can also be used to detect the so far unobserved copper(III) porphyrin dication. Electrochemical studies of the oxidation of (DPP)Cu and (OETPP)Cu show three processes, the first two of which are macrocycle-centered to give the porphyrin dication followed by a Cu(II)/Cu(III) process at more positive potential. Support for the assignment of the Cu(II)/Cu(III) process comes from the linear relationships observed between E1/2 and the third ionization potential of the central metal ions for iron, cobalt, nickel, and copper complexes of (DPP)M and (OETPP)M. In addition, the oxidation behavior of additional nonplanar nickel porphyrins is investigated in a noncoordinating solvent, with nickel meso-tetraalkylporphyrins also being found to form nickel(III) porphyrin dications. Finally, examination of the nickel meso-tetraalkylporphyrins in a coordinating solvent (pyridine) reveals that the first oxidation becomes metal-centered under these conditions, as was previously noted for a range of nominally planar porphyrins.

Ophthalmologic diagnostic tool using MR images for biomechanically-based muscle volume deformation

NASA Astrophysics Data System (ADS)

Buchberger, Michael; Kaltofen, Thomas

2003-05-01

We would like to give a work-in-progress report on our ophthalmologic diagnostic software system which performs biomechanically-based muscle volume deformations using MR images. For reconstructing a three-dimensional representation of an extraocular eye muscle, a sufficient amount of high resolution MR images is used, each representing a slice of the muscle. In addition, threshold values are given, which restrict the amount of data used from the MR images. The Marching Cube algorithm is applied to the polygons, resulting in a 3D representation of the muscle, which can efficiently be rendered. A transformation to a dynamic, deformable model is applied by calculating the center of gravity of each muscle slice, approximating the muscle path and subsequently adding Hermite splines through the centers of gravity of all slices. Then, a radius function is defined for each slice, completing the transformation of the static 3D polygon model. Finally, this paper describes future extensions to our system. One of these extensions is the support for additional calculations and measurements within the reconstructed 3D muscle representation. Globe translation, localization of muscle pulleys by analyzing the 3D reconstruction in two different gaze positions and other diagnostic measurements will be available.

Solubility parameters of HPMCAS have not yet been investigated intensively. On this account, total and three-dimensional solubility parameters of HPMCAS were determined by using different experimental as well as computational methods. In addition, solubility properties of HPMCAS in a huge number of solvents were tested and a Teas plot for HPMCAS was created. The total solubility parameter of about 24 MPa(0.5) was confirmed by various procedures and compared with values of plasticizers. Twenty common pharmaceutical plasticizers were evaluated in terms of their suitability for supporting film formation of HPMCAS under dry coating conditions. Therefore, glass transition temperatures of mixtures of polymer and plasticizers were inspected and film formation of potential ones was further investigated in dry coating of pellets. Contact angles of plasticizers on HPMCAS were determined in order to give a hint of achievable coating efficiencies in dry coating, but none was found to spread on HPMCAS. A few common substances, e.g. dimethyl phthalate, glycerol monocaprylate, and polyethylene glycol 400, enabled plasticization of HPMCAS; however, only triethyl citrate and triacetin were found to be suitable for use in dry coating. Addition of acetylated monoglycerides to triacetin increased coating efficiency, which was likewise previously demonstrated for triethyl citrate.

The coming decades will bring the next space telescopes to take on the ambitious goal of exoplanet discovery via direct imaging, driving the development of innovative coronagraphic solutions. High contrast imager for Complex Aperture Telescopes (HiCAT) is an optical testbed meant to test such solutions for complex aperture telescopes, such as the Large UV/Optical/InfraRed surveyor (LUVOIR), or any other segmented space observatory. High contrast imaging becomes more demanding with the addition of segments, a secondary mirror obscuration, and support structure. LUVOIR, a candidate for the next-next generation major space telescope funded in part by NASA, will have all three. In the past year, HiCAT has made significant hardware and software updates in order to meet the needs of LUVOIR. In addition to completely overhauling the software that runs the testbed, we have received the first two custom-made apodizers for the Apodized Pupil Lyot Coronagraph (APLC) that we are testing for LUVOIR, and are continuing the development of the wavefront sensing and control. This poster will serve to give an update on these, and other, changes, as well as the most recent results.

Buckling Design Studies of Inverted, Oblate Bulkheads for a Propellant Tank

NASA Technical Reports Server (NTRS)

Smeltzer, Stanley S., III; Bowman, Lynn M.

2002-01-01

An investigation of the deformation and buckling characteristics of a composite, oblate bulkhead that has an inverted geometry and is subjected to pressure-only loading is presented for three bulkhead geometries and thicknesses. The effects of a stiffening support ring at the bulkhead to cylinder interface are also evaluated. Buckling analyses conducted using the axisymmetric shell code BOSOR4 are discussed for several bulkhead configurations. These results are analytically verified using results from the Structural Analysis of General Shells (STAGS) code for a selected bulkhead configuration. The buckling characterization of an inverted, oblate bulkhead requires careful attention as small changes in bulkhead parameters can have a significant effect on the critical buckling load. Comparison of BOSOR4 and STAGS results provided a very good correlation between the two analysis methods. In addition, the analysis code BOSOR4 was found to be an efficient sizing tool that is useful during the preliminary design stage of a practical shell structure. Together, these two aspects should give the design engineer confidence in sizing these stability critical structures. Additional characterization is warranted, especially for a composite tank structure, since only one bulkhead configuration was examined closely.

Recent developments in the structural design and optimization of ITER neutral beam manifold

NASA Astrophysics Data System (ADS)

Chengzhi, CAO; Yudong, PAN; Zhiwei, XIA; Bo, LI; Tao, JIANG; Wei, LI

2018-02-01

This paper describes a new design of the neutral beam manifold based on a more optimized support system. A proposed alternative scheme has presented to replace the former complex manifold supports and internal pipe supports in the final design phase. Both the structural reliability and feasibility were confirmed with detailed analyses. Comparative analyses between two typical types of manifold support scheme were performed. All relevant results of mechanical analyses for typical operation scenarios and fault conditions are presented. Future optimization activities are described, which will give useful information for a refined setting of components in the next phase.

Runtime support for data parallel tasks

NASA Technical Reports Server (NTRS)

Haines, Matthew; Hess, Bryan; Mehrotra, Piyush; Vanrosendale, John; Zima, Hans

1994-01-01

We have recently introduced a set of Fortran language extensions that allow for integrated support of task and data parallelism, and provide for shared data abstractions (SDA's) as a method for communications and synchronization among these tasks. In this paper we discuss the design and implementation issues of the runtime system necessary to support these extensions, and discuss the underlying requirements for such a system. To test the feasibility of this approach, we implement a prototype of the runtime system and use this to support an abstract multidisciplinary optimization (MDO) problem for aircraft design. We give initial results and discuss future plans.

Prevention of distal extension cantilever fracture in mandibular overdentures.

PubMed

Quirynen, Thomas; Quirynen, Marc; Duyck, Joke

2015-09-01

Fractures of distal bar extensions, supporting a mandibular overdenture, do occur with significant functional and economic consequences for the patient. This study therefore aims to evaluate the effect of different bar cross-sectional shapes and surfaces, bar extension lengths and the placement of a support rib under the distal bar extension on fracture resistance. The 2nd moment area and static strength were calculated for 11 frequently used bar designs using finite element analysis (FEA). For two specific designs (Ackermann round Ø 1.8mm and Dolder-Y macro, the former with and without a support rib) additional physical static and fatigue strength tests were included. The FEA static strength data corresponded well to the 2nd moment area (a similar ranking when maximum allowed force was considered). The application of a rib support (Ackermann Ø 1.8mm) and limitations of the bar extension length (6mm for the Ackermann Ø 1.8mm, 8mm for the Dolder-Y macro) allowed the bars to exceed 5 × 10(6) cycles of 120 and 250N, respectively, before fracture. The region of highest stresses in FEA corresponded well with the locations of the fractures observed in static- and fatigue-testing. With some simple guidelines/modifications, the number of bar extension fractures can be reduced significantly. This study focusses on distal bar extensions which improve the positioning of an implant supported overdenture. By combining laboratory testing and finite element simulations we aim to: (1) explain why fractures occur (dependent on physical characteristics of the bar), and (2) give clinical guidelines on how to prevent such fractures.

Documentation of a Regional Aquifer Simulation Model RAQSIM, and a description of support programs applied in the Twin Platte - Middle Republican Study Area, Nebraska

USGS Publications Warehouse

Cady, R.E.; Peckenpaugh, J.M.

1985-01-01

RAQSIM, a generalized flow model of a groundwater system using finite-element methods, is documented to explain how it works and to demonstrate that it gives valid results. Three support programs that are used to compute recharge and discharge data required as input to RAQSIM are described. RAQSIM was developed to solve transient, two-dimensional, regional groundwater flow problems with isotropic or anisotropic conductance. The model can also simulate radially-symmetric flow to a well and steady-state flow. The mathematical basis, program structure, data input and output procedures, organization of data sets, and program features and options of RAQSIM are discussed. An example , containing listings of data and results and illustrating RAQSIM 's capabilities, is discussed in detail. Two test problems also are discussed comparing RAQSIM 's results with analytical procedures. The first support program described, the PET Program, uses solar radiation and other climatic data in the Jensen-Haise method to compute potential evapotranspiration. The second support program, the Soil-Water Program, uses output from the PET Program, soil characteristics, and the ratio of potential to actual evapotranspiration for each crop to compute infiltration, storage, and removal of water from the soil zone. The third program, the Recharge-Discharge Program, uses output from the Soil-Water Program together with other data to compute recharge and discharge from the groundwater flow system. For each support program, a program listing and examples of the data and results for the Twin Platte-Middle Republican study are provided. In addition, a brief discussion on how each program operates and on procedures for running and modifying these programs are presented. (Author 's abstract)

Nowadays, mental illnesses are gradually increasing and so does chronic psychiatric patients. As a result of this increase, chronic psychiatric disorders lead the burden of patients and their families. To reduce the burden of mental illnesses on individuals and their families, treatment and care are given including psychosocial, physiological and medical support and social services. To begin with, home care enables both the patient and his or her family to stay at their own houses and not to be bothered with residents or long-term, institutional-based nursing homes. In addition, the home care providers deliver services to the patient’s at their own house. The other advantages of taking care at home is that it eases financial issues in terms of reducing the cost, reduces the patient’s symptoms and improve the individual’s quality of life (QoL). In addition to these, home care also minimizes the burden on outpatient services and provides help for the patient and the family in order to solve their problems and give support. Home care services help patients to get their freedom back and enhance the quality of their lives. Thus, it is necessary to procure and implement these services and supply both the patient and his or her family a high-quality life. Sources of data/ study selection: Literature review was done by using the keywords “home care, patient with chronic mental illness, quality of life, home care nursing” from the sources including PsychINFO, PsychARTICLES, MEDLINE, PubMED, EBSCOHOST and The COCHRANE LIBRARY in the time period of 2005- 2015.

A Modular GIS-Based Software Architecture for Model Parameter Estimation using the Method of Anchored Distributions (MAD)

NASA Astrophysics Data System (ADS)

Ames, D. P.; Osorio-Murillo, C.; Over, M. W.; Rubin, Y.

2012-12-01

The Method of Anchored Distributions (MAD) is an inverse modeling technique that is well-suited for estimation of spatially varying parameter fields using limited observations and Bayesian methods. This presentation will discuss the design, development, and testing of a free software implementation of the MAD technique using the open source DotSpatial geographic information system (GIS) framework, R statistical software, and the MODFLOW groundwater model. This new tool, dubbed MAD-GIS, is built using a modular architecture that supports the integration of external analytical tools and models for key computational processes including a forward model (e.g. MODFLOW, HYDRUS) and geostatistical analysis (e.g. R, GSLIB). The GIS-based graphical user interface provides a relatively simple way for new users of the technique to prepare the spatial domain, to identify observation and anchor points, to perform the MAD analysis using a selected forward model, and to view results. MAD-GIS uses the Managed Extensibility Framework (MEF) provided by the Microsoft .NET programming platform to support integration of different modeling and analytical tools at run-time through a custom "driver." Each driver establishes a connection with external programs through a programming interface, which provides the elements for communicating with core MAD software. This presentation gives an example of adapting the MODFLOW to serve as the external forward model in MAD-GIS for inferring the distribution functions of key MODFLOW parameters. Additional drivers for other models are being developed and it is expected that the open source nature of the project will engender the development of additional model drivers by 3rd party scientists.
