    It presents the study of the cholesterol metabolism in rats. This thesis has been divided in three chapters. In a first part, it will discuss about the dynamic state of biological constituents in organism and in particular the dynamic state of cholesterol. This matter will be considered, firstly under its theoretical aspect and secondly under an experimental point of view with isotopic techniques. The current data on the dynamic state of cholesterol will allow to identify the essential points which are the subject of this research. In particular, the full understanding of the different cholesterol origins (diet, biosynthesis or formation of cholesterol from degradation or transformation of precursors as acetate or butyric acid for example) and the different cholesterol disappearance way (excretion, destruction, transformation or esters formation) is necessary to further research. In a second part, the experimental techniques and methods are described. A brief presentation of the methods for the study of the cholesterol transport and synthesis will be given as well as the experimental conditions and in particular the animal diet and cholesterol ingestion, the administration of acetate and {gamma}-phenyl {alpha}-aminobutyric. The different preparations of the {sup 14}C labelled cholesterol are also described as well as the extraction and measuring of the specific {sup 14}C radioactivity in the animal tissues extract, carbon dioxide gas and sodium acetate. Finally, the results will be given and discussed according to the way of intake: a radioactive cholesterol ingestion or an acetate intraperitoneal injection. (M.P.)

    Gazut, St

    2007-03-15

    This thesis addresses the problem of the construction of surrogate models in numerical simulation. Whenever numerical experiments are costly, the simulation model is complex and difficult to use. It is important then to select the numerical experiments as efficiently as possible in order to minimize their number. In statistics, the selection of experiments is known as optimal experimental design. In the context of numerical simulation where no measurement uncertainty is present, we describe an alternative approach based on statistical learning theory and re-sampling techniques. The surrogate models are constructed using neural networks and the generalization error is estimated by leave-one-out, cross-validation and bootstrap. It is shown that the bootstrap can control the over-fitting and extend the concept of leverage for non linear in their parameters surrogate models. The thesis describes an iterative method called LDR for Learner Disagreement from experiment Re-sampling, based on active learning using several surrogate models constructed on bootstrap samples. The method consists in adding new experiments where the predictors constructed from bootstrap samples disagree most. We compare the LDR method with other methods of experimental design such as D-optimal selection. (author)

  11. La nouvelle vague in polarized neutron scattering

    International Nuclear Information System (INIS)

    Mezei, F.

    1986-01-01

    Polarized neutron research, like many other subjects in neutron scattering developed in the footsteps of Cliff Shull. The classical polarized neutron technique he pioneered was generalized around 1970 to vectorial beam polarizations and this opened up the way to a ''nouvelle vague'' of neutron scattering experiments. In this paper I will first reexamine the old controversy on the question whether the nature of the neutron magnetic moment is that of a microscopic dipole or of an Amperian current loop. The problem is not only of historical interest, but also of relevance to modern applications. This will be followed by a review of the fundamentals on spin coherence effects in neutron beams and scattering, which are the basis of vectorial beam polarization work. As an example of practical importance, paramagnetic scattering will be discussed. The paper concludes with some examples of applications of the vector polarization techniques, such as study of ferromagnetic domains by neutron beam depolarization and Neutron Spin Echo high resolution inelastic spectroscopy. The sample results presented demonstrate the new opportunities this novel approach opened up in neutrons scattering research. (orig.)

  12. Paternal stress prior to conception alters DNA methylation and behaviour of developing rat offspring.

    Science.gov (United States)

    Mychasiuk, R; Harker, A; Ilnytskyy, S; Gibb, R

    2013-06-25

    Although there has been an abundance of research focused on offspring outcomes associated with maternal experiences, there has been limited examination of the relationship between paternal experiences and offspring brain development. As spermatogenesis is a continuous process, experiences that have the ability to alter epigenetic regulation in fathers may actually change developmental trajectories of offspring. The purpose of this study was to examine the effects of paternal stress prior to conception on behaviour and the epigenome of both male and female developing rat offspring. Male Long-Evans rats were stressed for 27 consecutive days and then mated with control female rats. Early behaviour was tested in offspring using the negative geotaxis task and the open field. At P21 offspring were sacrificed and global DNA methylation levels in the hippocampus and frontal cortex were analysed. Paternal stress prior to conception altered behaviour of all offspring on the negative geotaxis task, delaying acquisition of the task. In addition, male offspring demonstrated a reduction in stress reactivity in the open field paradigm spending more time than expected in the centre of the open field. Paternal stress also altered DNA methylation patterns in offspring at P21, global methylation was reduced in the frontal cortex of female offspring, but increased in the hippocampus of both male and female offspring. The results from this study clearly demonstrate that paternal stress during spermatogenesis can influence offspring behaviour and DNA methylation patterns, and these affects occur in a sex-dependent manner. Development takes place in the centre of a complex interaction between maternal, paternal, and environmental influences, which combine to produce the various phenotypes and individual differences that we perceive.

    2015-06-01

    Full Text Available This article is an introduction to the study of the close connection between phenomenology and the investigations on phantoms. We want to show that there is a deep kinship between phenomena and phantoms and that Husserl’s phenomenological project, as well as, more specifically, its original reinstitution by Merleau-Ponty, lead us to think the real on the basis of a reference to phantoms regarded as ontological models. Our analyses will be based more precisely on Merleau-Ponty’s study of the phantom-limb in Phenomenology of Perception. We will contend that the body itself, through the concepts of body schema and of structure [Gestalt], is eventually thought of by Merleau-Ponty as possessing the same mode of being as phantoms.

  2. New concept in allergy: Non-allergic rats becomes allergic after induced by Porphyromonas gingivalis lipopolysaccharide

    Directory of Open Access Journals (Sweden)

    Haryono Utomo

    2013-06-01

    Full Text Available Background: As a theory, seemingly it is impossible that allergic diseases, including asthma, are the result of exposure to a transmissible agent. The fact that nearly all children with asthma are allergic, but only a small proportion of allergic children have asthma, at least raises the possibility that other factors are involved. Interestingly, non-allergic children become allergic after their parents came from working in allergic people for several months. Recent research revealed that periodontal pathogens are also transmissible from mother and caregivers to infants.Therefore, it is logical that non-allergic children could become allergic after exposed to periodontopathic bacteria. However, the mechanism is still unclear. Purpose: The objective of this study is to verify a new concept that non-allergic rat may become allergic after exposed to Porphyromonas gingivalis lipopolysaccharide. Methods: Randomized control series design experimental study was conducted to 24 male Wistar rats, two experimental groups and one control group. One group was subjected to intrasulcular injection of PgLPS1435/1450. Tissue examination were done for allergy biomarkers with peroxidase immunohistochemistry for leukotriene C4 (LTC4 and eosinophilic cationic protein (ECP in bronchus tissue. Serum level examination of interleukin 4 (IL-4, and immunoglobulin E (IgE was done with ELISA. Data were analyzes using ANOVA. Results: after four days, LTC4 and ECP expression increased significantly (p=0.001; even insignificant, IL-4 and IgE serum level also increased. Conclusion: PgLPS is able to stimulate immunocompetent cells which changed the host immune response of non-allergic rats. Therefore, it is possible that they become allergic.Latar belakang: Menurut teori, penularan penyakit alergi termasuk asma merupakan hal yang mustahil.

    As part of the public-interest mission with which it has been tasked by the public authorities, IFP Energies Nouvelles (IFPEN) focuses on: - providing solutions to take up the challenges facing society in terms of energy and the climate, promoting the emergence of a sustainable energy mix, - creating wealth and jobs by supporting French and European economic activity, and the competitiveness of related industrial sectors. Despite the current economic environment, 2014 was a good year for IFPEN. In the field of renewable energies, major milestones were reached in two significant projects dedicated to the production of second generation biofuels in which IFPEN is very actively involved: processes developed in Futurol TM are already in the pre-marketing phase, while the construction of the two pilot units for the BioTfueL project has just been launched. In the field of ocean energies, IFPEN research has led to the first partnership agreements relating to floating wind turbines anchor technologies and command control systems for wind energy and wave energy conversion. In the transport sector, game-changing concepts are beginning to emerge, such as smart battery charging and a Rankine cycle system for an internal combustion engine transforming combustion heat into energy. In addition, IFPEN have joined forces with innovative SMEs to boost their research in the fields of electric power-trains and power electronics. Finally, IFPEN launched an eco-driving application that has proved extremely popular with the public. Turning now to oil and gas, IFPEN continued to expand its range of basin and reservoir simulation, modeling and characterization software, and it signed several contracts in the field of chemical enhanced recovery solutions with its EOR (Enhanced Oil Recovery) Alliance TM partners. IFPEN also developed new generations of high-performance catalysts and improved the conversion rate of its processes to enable refiners to convert increasingly heavy crudes and

    The isotopic equilibrium method which has been developed in the case of the rat has made it possible to measure the absolute values of the principal parameters of iodine metabolism in this animal. The quantities and concentrations of iodine have been measured in the thyroid gland and in the plasma with a sensitivity of 0.001 {mu}g of {sup 127}I. This sensitivity has made it possible to measure pools as small as the iodide and the free iodotyrosines of the thyroid and to demonstrate the absence of free iodotyrosines in the plasma of the normal rat. In vivo, the isotopic equilibrium method has made it possible to measure the iodine content of the thyroid gland and to calculate the intensity of this gland's secretion without removing it. By double labelling with {sup 125}I and {sup 131}I the isotopic equilibrium method has made it possible to measure the flux, intensity of the intrathyroidal recycling as well as the turnover rates of all the iodine containing compounds of the thyroid gland. For this gland no precursor-product relationship has been found between The iodotyrosines (MIT and DIT) and the iodothyronines (T{sub 4} and T{sub 3}). The absence of this relationship is due to the heterogeneity of the thyroglobulin turnover. It has been shown furthermore that there exists in the plasma an organic fraction of the iodine which is different to thyroglobulin and which is renewed more rapidly than the circulating hormones T{sub 3} and T{sub 4}. The isotopic equilibrium method is very useful for series measurements of iodine. It makes it possible furthermore to improve the biochemical fractionations by adding carriers without affecting the subsequent {sup 127}I measurements.

  9. A Novel Concept of Amino Acid Supplementation to Improve the Growth of Young Malnourished Male Rats.

    Furuta, Chie; Murakami, Hitoshi

    2018-01-01

    This study was aimed at understanding the relationship between plasma amino acids and protein malnutrition and at determining whether amino acid supplementation associated with malnutrition and growth improves linear growth in growing rats. Body length and plasma amino acids were measured in young male rats that were fed the following diet for 3 weeks, mimicking a low and imbalanced protein diets based on maize, a major staple consumed in developing countries: a 70% calorically restricted cornmeal-based diet (C), C + micronutrients (CM), CM + casein (CMC), CM + soy protein (CMS) or CMS + 0.3% lysine. A correlation analysis of linear growth and plasma amino acids indicated that lysine, tryptophan, branched-chain amino acids, methionine, and phenylalanine significantly correlated with body length. Supplementation with these 5 amino acids (AA1) significantly improved the body length in rats compared to CMC treatment whereas, nitrogen-balanced amino acid supplemented controls (AA2) did not (CM +1.2 ± 0.2, CMC +2.7 ± 0.3, CMS +2.1 ± 0.3, AA1 +2.8 ± 0.2, and AA2 +2.5 ± 0.3 cm). With securing proper amino acid balance, supplementing growth-related amino acids is more effective in improving linear growth in malnourished growing male rats. Analysis of the correlation between plasma amino acids and growth represents a powerful tool to determine candidate amino acids for supplementation to prevent malnutrition. This technology is adaptable to children in developing countries. © 2018 S. Karger AG, Basel.

  14. A further study on the concept of top-up dose of spinal cord on rats

    1993-01-01

    The concept of top-up dose has been used in the study on process of spinal cord repair in multiple radiation treatment in order to avoid cellular proliferation and animal loss. This study indicates that top up dose could be given 24 h or 6 weeks after completion of radiation treatment without significant difference of biological effects. It is suggested that the radiobiological effect could be reduced if 16 Gy of top-up dose is used in the multiple treatment instead of half of the number of treatment. A possible mechanism is discussed

  15. The effect of small radiation doses on the rat spinal cord: the concept of partial tolerance

    International Nuclear Information System (INIS)

    Ang, K.K.; Van Der Kogel, A.J.; Van Der Schueren, E.

    1983-01-01

    To evaluate the tolerance of the rat spinal cord to small radiation doses per fraction, an increasing number of fractions is required for induction of paralysis. The assessment of doses of 1-2 Gy, as used in the clinic, would require that over 100 fractions be given. The validity of replacing part of a fractionated irradiation of the spinal cord by a single large dose has been tested. Fractionated irradiation doses with 18 MeV X rays were followed by a ''top-up'' dose of 15 Gy as a single treatment. This is the fraction size of a treatment with two irradiation doses leading to paralysis in 50% of the animals (ED 50). Fractionated treatments were carried out with 2, 5, 10 and 20 fractions followed by the top-up dose of 15 Gy. the isoeffect curve, as a function of the number of fractions, has the same slope as experiments performed without top-up dose. The results show that the quality and quantity of cellular repair is not modified when part of a multifractionated exposure is replaced by a larger top-dose. An important consequence of this finding is, that in treatments with unequal fraction sizes, the partial tolerances can simply be added. Since a top-up dose can replace a sizable number of irradiation treatments, its application will allow investigations of the extent of sublethal damage repair for fraction sizes as low as 1 Gy

  16. Triple-Gene Therapy for Stroke: A Proof-of-Concept in Vivo Study in Rats

    2018-02-01

    Full Text Available Natural brain repair after stroke is extremely limited, and current therapeutic options are even more scarce with no clinical break-through in sight. Despite restricted regeneration in the central nervous system, we have previously proved that human umbilical cord blood mono-nuclear cells (UCB-MC transduced with adenoviral vectors carrying genes encoding vascular endothelial growth factor (VEGF, glial cell-derived neurotrophic factor (GDNF, and neural cell adhesion molecule (NCAM successfully rescued neurons in amyotrophic lateral sclerosis and spinal cord injury. This proof-of-principle project was aimed at evaluating the beneficial effects of the same triple-gene approach in stroke. Rats subjected to distal occlusion of the middle cerebral artery were treated intrathecally with a combination of these genes either directly or using our cell-based (UCB-MC approach. Various techniques and markers were employed to evaluate brain injury and subsequent recovery after treatment. Brain repair was most prominent when therapeutic genes were delivered via adenoviral vector- or UCB-MC-mediated approach. Remodeling of brain cortex in the stroke area was confirmed by reduction of infarct volume and attenuated neural cell death, depletion of astrocytes and microglial cells, and increase in the number of oligodendroglial cells and synaptic proteins expression. These results imply that intrathecal injection of genetically engineered UCB-MC over-expressing therapeutic molecules (VEGF, GDNF, and NCAM following cerebral blood vessel occlusion might represent a novel avenue for future research into treating stroke.

    2016-01-01

    Intraarterial microdosing (IAM) is a novel drug development approach combining intraarterial drug delivery and microdosing. We aimed to demonstrate that IAM leads to target exposure similar to that of systemic full-dose administration but with minimal systemic exposure. IAM could enable the safe, inexpensive, and early study of novel drugs at the first-in-human stage and the study of established drugs in vulnerable populations. Methods Insulin was administered intraarterially (ipsilateral femoral artery) or systemically to 8 CD IGS rats just before blood sampling or 60-min 18F-FDG uptake PET imaging of ipsilateral and contralateral leg muscles (lateral gastrocnemius) and systemic muscles (spinotrapezius). The 18F-FDG uptake slope analysis was used to compare the interventions. Plasma levels of insulin and glucose were compared using area under the curve calculated by the linear trapezoidal method. A physiologically based computational pharmacokinetics/pharmacodynamics model was constructed to simulate the relationship between the administered dose and response over time. Results 18F-FDG slope analysis found no difference between IAM and systemic full-dose slopes (0.0066 and 0.0061, respectively; 95% confidence interval [CI], −0.024 to 0.029; P = 0.7895), but IAM slope was statistically significantly greater than systemic microdose (0.0018; 95% CI, −0.045 to −0.007; P = 0.0147) and sham intervention (−0.0015; 95% CI, 0.023–0.058; P = 0.0052). The pharmacokinetics/pharmacodynamics data were used to identify model parameters that describe membrane insulin binding and glucose–insulin dynamics. Conclusion Target exposure after IAM was similar to systemic full dose administration but with minimal systemic effects. The computational pharmacokinetics/pharmacodynamics model can be generalized to predict whole-body response. Findings should be validated in larger, controlled studies in animals and humans using a range of targets and classes of drugs. PMID

    Full Text Available We aimed to perform a chemical analysis of both Alibernet red wine and an alcohol-free Alibernet red wine extract (AWE and to investigate the effects of AWE on nitric oxide and reactive oxygen species production as well as blood pressure development in normotensive Wistar Kyoto (WKY and spontaneously hypertensive rats (SHRs. Total antioxidant capacity together with total phenolic and selected mineral content was measured in wine and AWE. Young 6-week-old male WKY and SHR were treated with AWE (24,2 mg/kg/day for 3 weeks. Total NOS and SOD activities, eNOS and SOD1 protein expressions, and superoxide production were determined in the tissues. Both antioxidant capacity and phenolic content were significantly higher in AWE compared to wine. The AWE increased NOS activity in the left ventricle, aorta, and kidney of SHR, while it did not change NOS activity in WKY rats. Similarly, increased SOD activity in the plasma and left ventricle was observed in SHR only. There were no changes in eNOS and SOD1 expressions. In conclusion, phenolics and minerals included in AWE may contribute directly to increased NOS and SOD activities of SHR. Nevertheless, 3 weeks of AWE treatment failed to affect blood pressure of SHR.

    For the last 15 years, animal models that mimic human disorders have become ubiquitous participants to understand biological mechanisms and human disorders and to evaluate new therapeutic approaches. The necessity to study these models in the course of time has stimulated the development of instruments dedicated to in vivo small animal studies. To further understand physiopathological processes, the current challenge is to couple simultaneously several of these methods. Given this context, the combination of the magnetic and radioactive techniques remains an exciting challenge since it is still limited by strict technical constraints. Therefore we propose to couple the magnetic techniques with the radiosensitive Beta-Microprobe, developed in the IPB group and which shown to be an elegant alternative to PET measurements. In this context, the thesis was dedicated to the study of the coupling feasibility from a physical point of view, by simulation and experimental characterizations. Then, the determination of a biological protocol was carried out on the basis of pharmacokinetic studies. The experiments have shown the possibility to use the probe for radioactive measurements under intense magnetic field simultaneously to anatomical images acquisitions. Simultaneously, we have sought to improve the quantification of the radioactive signal using a voxelized phantom of a rat brain. Finally, the emergence of transgenic models led us to reproduce pharmacokinetic studies for the mouse and to develop voxelized mouse phantoms. (author)

  15. Modeling volume effects of experimental brachytherapy in the rat rectum: uncovering the limitations of a radiobiologic concept

    Johannessen, Hans-Olaf; Dale, Einar; Hellebust, Taran P.; Olsen, Dag R.; Nesland, Jahn M.; Giercksky, Karl-Erik

    2002-01-01

    Purpose: To analyze the significance of volume effects in experimental brachytherapy, based on modeling normal tissue complication probability. Methods and Materials: Experimental brachytherapy in the rat rectum was based on an eight-step 2.5-mm step size source configuration for 192 Ir, afterloaded into an unshielded polystyrene applicator. Volume effects were studied using a half-circumferential lead-shielded applicator and a shorter (two-step) source configuration. The main end point was rectal stenosis. Results: Rectal stenosis was always caused by a radiation ulcer. With the shielded configuration, single-dose ED 50 (50% incidence of rectal stenosis) increased from 23 Gy to 36.5 Gy. Single-dose ED 50 for the short configuration was 77.9 Gy. The data showed a reasonable fit to a three-parameter version of the biophysical model described by Jackson et al. (1995). This model assumes that organs consist of a large number of radiobiologically independent subunits and that radiation causes a complication if the fraction of the organ damaged is greater than its functional reserve. The fraction of the organ damaged is calculated summing over fractions of the organ damaged at each dose level. The calculated mean functional reserve (ν 50 ) of the rat rectum, assuming a cumulative functional reserve distribution in the group of experimental rats, was 0.53. Conclusions: The volume effect observed within small brachytherapy volumes agreed well with clinical experience of large tolerance doses in contact X-ray therapy. However, the ν 50 value was comparable to the high functional reserve value reported for liver. Experimental volume effects probably reflect repair processes originating in the areas adjacent to small radiation fields of brachytherapy more than the radiobiologic characteristics of the cells in the irradiated volume

    The duration of the S-phase of supporting cells and wall cells of rat fetuses aged 19 days was determined by the ''labelled mitosis'' method. The supporting cells are predecessors of the sertoli cells while the wall cells are predecessors of the boundary tissue and, possibly, of part of the peritubular Leydig cell system. The S-phase of the supporting cells was found to last 10.1 h while the S-phase of the wall cells lasted 9.2 h. The data were not in agreement with the data of other authors. (orig./MG) [de

L’article montre l’enracinement de ces nouvelles thérapies dans des représentations sociales et des modèles culturels de l’étiologie du cancer et du “faire face” à la maladie qui permettent ou renforcent l’adoption et l’appropriation de la pensée psychosomatique alternative.New alternative therapy called « bio-decoding » based on a psychosomatic perception of cancer appeared in the 1990s. Using a critical approach, the article aims to understand the therapy’s growth. Drawing on D. Fassin’s work about ethnopsychiatric networks, this paper analyses the construction of bio-decoding and bio-therapist legitimacy, by unravelling the networks which allow for theory dissemination and enable the practice’s growth. The article shows that these new therapies are deeply rooted in social and cultural models of cancer etiology and coping, which allow or reinforce approval and appropriation of alternative psychosomatic thought.

    One of the largest habitable green roofs in the New England area was designed by Martha Schwartz Inc. The green roof spans 1.5 acres of mall rooftop that will be accessible by two connected condominium towers. A condominium complex associated with the expansion of the Natick Mall entitled Nouvelle, offers a new type of housing, in which a private, residential apartment complex adjoins a suburban, upscale indoor shopping mall. There are many new opportunities to use the expansive area of the mall complex roof to function as a productive, multi-use, shared private park. As an art-based landscape architectural practice, the office has adapted bold and graphic qualities as a model for its green roof design. The Nouvelle green roof offers dynamic circulation, enjoyable social space and recreation, intersecting a continuous coverage of patterned sedum and river stone that spans an entire roofscape. The green roof demonstrates an innovative combination of intensive and extensive plantings that create a system of legible and visually pleasing patterning from above. This case study addressed these innovations and implementation challenges within the context of mall architecture and green roof technologies. In addition, it also identified the social uses of roof spaces, and the aesthetics and sustainability of patterning in intensive and extensive planting design.

    Ultrasound-targeted microbubble destruction (UTMD) is a novel means of tissue-specific gene delivery. This approach systemically infuses transgenes precoupled to gas-filled lipid microbubbles that are burst within the microvasculature of target tissues via an ultrasound signal resulting in release of DNA and transfection of neighboring cells within the tissue. Previous work has shown that adenovirus containing cDNA of UCP-1, injected into the epididymal fat pads in mice, induced localized fat depletion, improving glucose tolerance, and decreasing food intake in obese diabetic mice. Our group recently demonstrated that gene therapy by UTMD achieved beta cell regeneration in streptozotocin (STZ)-treated mice and baboons. We hypothesized that gene therapy with BMP7/PRDM16/PPARGC1A in skeletal muscle (SKM) of obese Zucker diabetic fatty (fa/fa) rats using UTMD technology would produce a brown adipose tissue (BAT) phenotype with UCP-1 overexpression. This study was designed as a proof of concept (POC) project. Obese Zucker rats were administered plasmid cDNA contructs encoding a gene cocktail with BMP7/PRDM16/PPARGC1A incorporated within microbubbles and intravenously delivered into their left thigh. Controls received UTMD with plasmids driving a DsRed reporter gene. An ultrasound transducer was directed to the thigh to disrupt the microbubbles within the microcirculation. Blood samples were drawn at baseline, and after treatment to measure glucose, insulin, and free fatty acids levels. SKM was harvested for immunohistochemistry (IHC). Our IHC results showed a reliable pattern of effective UTMD-based gene delivery in enhancing SKM overexpression of the UCP-1 gene. This clearly indicates that our plasmid DNA construct encoding the gene combination of PRDM16, PPARGC1A, and BMP7 reprogrammed adult SKM tissue into brown adipose cells in vivo. Our pilot established POC showing that the administration of the gene cocktail to SKM in this rat model of genetic obesity using UTMD

    Diners at CERN's Restaurant No. 1 have been adjusting to some temporary arrangements while building work takes place in the main service area. The essential renovation will bring many improvements in the near future. The restaurant before restoration. A huge white marquee erected on a green lawn greets the eye. The sight is familiar in the summer months, but the sharp chill in the air disrupts the scene. Instead of a mid-summer's day, it's actually the middle of January. This apparently strange reversal of seasons is a way of providing an additional dining and service area outside Restaurant No. 1. As renovations get underway inside, the mysterious hum of drills and the hollow echo of hammering behind scaffold boards raise our curiosity about what is in-store. 'Everything will be better,' says Mario Zanolini, head waiter of Restaurant No. 1. 'It will be more comfortable for the customers. The free-flow area will be bigger and there will be 7 tills instead of the previous 5.' These are just for starters. ...

    Full Text Available Le questionnement de Foucault sur la judiciarisation des sociétés contemporaines renvoie à plusieurs controverses qui, entre 1974 et 1976, ont spécifiquement concerné la question du vivant comme de son rapport au champ du droit et des institutions politiques. Ces polémiques se sont cristallisées autour d'affaires judiciaires retentissantes mais également autour d'un discours technique et politique qui donne une place nouvelle aux notions de dangerosité, de sécurité et à la question plus générale de la gestion du vivant. Trois discours qui, pour Foucault, sont révélateur d'un profond changement de société et de mode de gouvernement des individus.

    Un debat de plus d'un siecle a resurgi ces toutes dernieres annees avec une vigueur nouvelle. L'enjeu ? Mettre fin, ni plus ni moins, a l'une des contradictions les plus inouies de la physique fondamentale, en reconciliant mecanique quantique et relativite generale. En effet, a l'heure ou la gravitation semble enfin sur le point de fusionner avec les trois autres forces de la nature. il est certain que la relativite d'Einstein doit etre bientot remplacer par une autre theorie... Reste quye tous les physiciens sont loin de s'accorder sur la marche a suivree. Gravitation quantique, relativite d'echelle, supersymetrie, les candidates ne manquent pas.

    Full Text Available Cet article montre en quoi plusieurs auteurs de la Nouvelle sociologie économique tendent à adopter un regard incomplet sur les forces du marché. Pour cela, l’auteur distingue deux notions d’encastrement renvoyant pour la première à un cadre méthodologique institutionnaliste et pour la seconde à l’observation du poids variable des forces du marché. Il établit qu’autant des sociologues classiques comme Weber ou Polanyi ont su coupler ces deux approches, autant plusieurs travaux majeurs de la Nouvelle sociologie économique, notamment ceux de Zelizer, de Fligstein et de Biggart, adoptent la première perspective mais ne traitent que de façon partielle de la seconde. L’auteur met particulièrement en cause les objets de recherche retenus par ces derniers auteurs, dès lors que sont systématiquement privilégiées des situations où les forces du marché sont tenues à l’écart.This article shows how many authors of the New Economic Sociology tend to adopt an incomplete view of market forces. The author distinguishes two notions of embeddedness, one related to the institutionalist theories and the second to the observation of the variable weight of market forces. It is established that classical sociologists such as Weber or Polanyi have joined these two approaches, while manyu works of the New sociological economy, for examle those of Zelizer, Fligstein or Biggart adopt the first perspective, but only treat the second partially. The author particularly questions the research objects chosen by these authors, since he considers that they generally refer to situations where market forces are held at bay.

    Directory of Open Access Journals (Sweden)

    Marine Buissonnière

    2012-04-01

    Full Text Available Les quinze dernières années ont été marquées par l’avènement de nouveaux acteurs dans le champ de la santé globale et l’augmentation de l’aide au développement en faveur de la santé. Ces acteurs ont capté une partie importante des ressources privées et publiques supplémentaires disponibles et se sont imposés comme les pièces maîtresses de ce nouvel échiquier, aux dépens des institutions traditionnelles qui ont graduellement perdu leur prépondérance et ont vu leur leadership s’affaiblir. Les choix et politiques de santé ont peu à peu échappé à la seule autorité des institutions qui en avaient jusqu’alors le mandat et en assumaient la charge. Certains pans entiers de la santé sont désormais dominés par des financeurs privés, devenus de facto prescripteurs d’orientations de santé publique. Cette nouvelle donne pose des questions essentielles de gouvernance et de responsabilité. Qui décide des orientations ? Comment les décisions sont-elles prises ? Les pays destinataires de l’aide doivent encore trop souvent subir le manque de coordination des donateurs et l’absence d’alignement des agendas. Dans ce contexte, et en prenant acte de cette nouvelle réalité, quelques pistes mériteraient d’être explorées afin de garantir que les orientations en matière de santé globale reflètent au mieux la réalité des besoins et les aspirations des pays.

    This publication first proposes graphs and comments characterising final energy consumption of the Nouvelle Aquitaine region: regional situation in 2015 (analysis per sector and per energy), primary resources, social-economic analysis (energy bill, level of energy poverty, burden due to old housing and commuting for households), evolution of energy consumption between 2005 and 2015 (per sector, per source of energy, evolution of energy intensity and of the energy bill). The next part addresses greenhouse gas emissions: regional situation in 2015 (distribution in terms of emission type and per gas), evolutions between 1990 and 2015, evolutions per sector. The third part addresses renewable energies: regional situation for the different types of renewable energy, comparison with final energy consumption, comparison with national data, production evolutions, focus per sector (wood and wood by-products, heat pumps in the housing sector, urban waste valorisation units, biogas valorisation, bio-fuels, wind energy, hydroelectricity, solar photovoltaic). The last part recalls national objectives related to energy, to greenhouse gas emissions for France and for the region, in relationship with the law on energy transition and for a green growth

    2011-01-01

    Le système Radio Fréquence (RF) 200MHz du PS est un outil essentiel pour la préparation des faisceaux haute intensité du PS. Dans l’anneau PS on trouve 6 cavités 200 MHz utilisées pour contrôler : • l’émittance longitudinale des « bunches » • le processus de « Rebunching » du faisceau avant de l’envoyer au SPS. Chaque cavité est pilotée par des événements appelés « timing » et suit une fonction de tension programmée. Cependant, l’électronique utilisée pour piloter les cavités 200 MHz du PS est obsolète et sa fiabilité non garantie pour cause du manque de pièces de rechange. Ce document décrit le fonctionnement du nouveau programme d’application qui fait abstraction de l’ancienne matrice hardware. Elle suit les recommandations décrites dans l’étude d’une nouvelle structure pour le système RF 200MHz du PS. [1

  18. How the Nouvelle Vague Invented the DVD: Cinephilia, new waves and film culture in the age of digital dissemination

    Directory of Open Access Journals (Sweden)

    Malte Hagener

    2014-01-01

    Full Text Available Whereas the currently emerging configurations of audiovisualcy in the age of digital networks are often addressed in terms of absolute novelty and innovation, this article wishes to shift the focus slightly, articulating instead the new in terms of the old. This essay proposes the argument that it was within the Nouvelle Vague and the French film culture of the 1960s that the DVD was “invented”. Obviously, this is a contrafactual argument, but if we understand the DVD as a discursive construction articulating a specific perspective on film, then the DVD simulates and emulates some key features of 1960s cinephilia that emerged within the context of the new waves. On the other hand, the Nouvelle Vague is understood as a broad discursive movement encompassing all segments of the institution cinema rather than five auteur-directors — Truffaut, Godard, Chabrol, Rohmer and Rivette — and their respective films. By arguing for the continuing importance of film history and culture, this article wishes to underline the fact that technological as well as aesthetic transformations are central to our understanding of media culture.

  19. Elaboration de nouvelles approches micromecaniques pour l'optimisation des performances mecaniques des materiaux heterogenes

    Science.gov (United States)

    Aboutajeddine, Ahmed

    Les modeles micromecaniques de transition d'echelles qui permettent de determiner les proprietes effectives des materiaux heterogenes a partir de la microstructure sont consideres dans ce travail. L'objectif est la prise en compte de la presence d'une interphase entre la matrice et le renforcement dans les modeles micromecaniques classiques, de meme que la reconsideration des approximations de base de ces modeles, afin de traiter les materiaux multiphasiques. Un nouveau modele micromecanique est alors propose pour tenir compte de la presence d'une interphase elastique mince lors de la determination des proprietes effectives. Ce modele a ete construit grace a l'apport de l'equation integrale, des operateurs interfaciaux de Hill et de la methode de Mori-Tanaka. Les expressions obtenues pour les modules globaux et les champs dans l'enrobage sont de nature analytique. L'approximation de base de ce modele est amelioree par la suite dans un nouveau modele qui s'interesse aux inclusions enrobees avec un enrobage mince ou epais. La resolution utilisee s'appuie sur une double homogeneisation realisee au niveau de l'inclusion enrobee et du materiau. Cette nouvelle demarche, permettra d'apprehender completement les implications des approximations de la modelisation. Les resultats obtenus sont exploites par la suite dans la solution de l'assemblage de Hashin. Ainsi, plusieurs modeles micromecaniques classiques d'origines differentes se voient unifier et rattacher, dans ce travail, a la representation geometrique de Hashin. En plus de pouvoir apprecier completement la pertinence de l'approximation de chaque modele dans cette vision unique, l'extension correcte de ces modeles aux materiaux multiphasiques est rendue possible. Plusieurs modeles analytiques et explicites sont alors proposee suivant des solutions de differents ordres de l'assemblage de Hashin. L'un des modeles explicite apparait comme une correction directe du modele de Mori-Tanaka, dans les cas ou celui ci echoue a

    Full Text Available La Nouvelle Revue Française, opgericht in 1908 door een groep schrijvers rond André Gide, is het belangrijkste Franse literaire maandblad van het interbellum geweest. In de jaren voorafgaand aan de Eerste Wereldoorlog is de reputatie van het tijdschrift nog relatief bescheiden, maar er is al wel een duidelijke progressie te constateren. Deze is niet alleen toe te schrijven aan de inhoudelijke kwaliteit van de bijdragen, maar vooral ook aan de manier waaorp de redactie het tijdschrift promoot. De oprichters bedienen zich van een 'mutimedia-strategie': zij ontwikkelen rond de NRF verschillende nevenactiviteiten om de naamsbekendheid van het tijdschrift te vergroten en zijn literatuuropvattingen onder een breder publiek te verspreiden.

    Full Text Available The historic importance of Theosophy within the realm of education is due to their presence in their reflexions and educational endeavours are at the origins of that nebulous movement called the New Education (éducation nouvelle. Their presence at the beginning of the organization of the New Education has been explored by several pioneering papers, but remains the blind spot in this area. In fact Theosophy’s influence has been felt but rarely analysed as the matrix of the nebulous international organization of new education. If the Theosophists’ influence were to be recognised, we think that their role, their persistent work that brought on not only the rise of new education, more specifically, the constitution of the International League of New Education but was also the making of educators of Theosophy teachings such as María Montessori and Rudolf Steiner who were not only the roots of the new education but also its main components.

Formal concept analysis (FCA) as a methodology of data analysis, information management and knowledge representation has potential to be applied to a verity of linguistic problems. FCA is mathematical theory for concepts and concept hierarchies that reflects an understanding of concept. Formal concept analysis explicitly formalizes extension and intension of a concept, their mutual relationships. A distinguishing feature of FCA is an inherent integration of three components of conceptual processing of data and knowledge, namely, the discovery and reasoning with concepts in data, discovery and reasoning with dependencies in data, and visualization of data, concepts, and dependencies with folding/unfolding capabilities.

    Future nuclear power plants will be different from present day ones because uranium resources are limited and not efficiently used by today's reactors. Several new reactor concepts have been examined by international experts in the framework of the generation 4 international forum. Five among the six reactor concepts retained concern FBR-type reactors which allow to efficiently convert {sup 238}U into plutonium which is continuously consumed and regenerated. One challenge concerns the development of high temperature and radiation resistant materials for reactors operating at higher temperature (> 600 deg. C) and offering new industrial applications of nuclear energy like hydrogen generation and seawater desalination. Another priority concerns the management of wastes, in particular the chemical separation of all actinides, including plutonium. A prototype of reactor of 4. generation is expected for 2020 before its industrial implementation by 2040. Short paper. (J.S.)

    Full Text Available La réforme dite de dévolution (décentralisation, votée en 1997, a entraîné de multiples conséquences et transformations dans la vie politique britannique. Le système traditionnellement unitaire de Westminster s’en est trouvé profondément bouleversé. Pourtant, tandis que de nombreuses études furent menées sur les divers nouveaux aspects d’une Grande-Bretagne dévolue, peu se sont penchées sur les conséquences de cette nouvelle asymétrie constitutionnelle sur l’Angleterre. Lorsque des députés de circonscriptions « celtiques » (en Écosse ou au pays de Galles arrivent à influencer le résultat de votes sur des affaires exclusivement anglaises, certains députés d’Angleterre, à Westminster, ne peuvent que se sentir désarmés face au manque de dispositions constitutionnelles garantissant un statut particulier pour ce territoire. Dès lors, de cette « question anglaise » (« English Question », naîtra toute une nouvelle mouvance autonomiste entièrement dédiée à l’obtention d’un Parlement anglais.Devolution at the end of the 1990s has led to numerous consequences and transformations in British politics. The traditional and centralised Westminster system has been turned upside down, and many studies have been carried out on the various aspects of this new “devolved Britain”.Yet, few have paid attention to the English case. However, the constitutional asymmetry thus created has indeed also affected England. When Celtic MPs succeed to influence the outcome of votes on exclusively English matters, one can realise that there is no such thing as an English government. Therefore, some English MPs have felt the need to ask for an option of “English Votes on English Laws”. This article tries to demonstrate that a feeling of “resentment” emerges from this situation and leads to the birth of a new “English” nationalism, entirely dedicated to obtaining an English Parliament.

    Full Text Available La « globalisation » des discours de la mosquée casse les frontières érigées historiquement par les différentes écoles, et tend à réduire la fracture inaugurale entre sunnisme et chiisme. Aujourd’hui il y a un retour à la Salafiya qui ne reconnaît que les fondamentaux. Tout le reste est considéré comme de l’ordre de l’historique et donc non sacré et à ce titre susceptible d’être laissé de côté ou changé. La Salafiya continue cependant à être divisée entre djâmida et djihâdiya.Les pratiques au sein de la mosquée procèdent également par pluralisation où l’individu cherche à la fois à signaler son individualité mais aussi à s’inscrire dans des tendances plus globales. Les récits de vie de différents imams laisse transparaître une sorte de sécularisation interne de la mosquée et une plus grande latitude dans la ré interprétation de l’initial.Les changements sont perceptibles également au niveau des acteurs De nouvelles figures concurrencent celle classique de l’imam. Le prédicateur, sans être une figure tout à fait nouvelle, ni une invention récente, demeure une figure réinventée.

    Statins and sartans can, in therapeutic doses, induce pleiotropic cardiovascular effects. Similar has recently been shown also for sub-therapeutic doses. We thus explored and compared the cardiovascular pleiotropic efficacy of sub-therapeutic vs. therapeutic doses. Wistar rats were randomly divided into 7 groups receiving fluvastatin, valsartan and their combination in sub-therapeutic and therapeutic doses, or saline. After 6weeks, the animals were euthanised, their hearts and thoracic aortas isolated, and blood samples taken. Endothelium-dependent relaxation of the thoracic aortae and ischaemic-reperfusion injury of the isolated hearts were assessed along with the related serum parameters and genes expression. Fluvastatin and valsartan alone or in combination were significantly more effective in sub-therapeutic than therapeutic doses. The sub-therapeutic combination greatly increased thoracic aorta endothelium-dependent relaxation and maximally protected the isolated hearts against ischaemia-reperfusion injury and was thus most effective. Beneficial effects were accompanied by increased levels of nitric oxide (NO) and decreased levels of asymmetric dimethylarginine (ADMA) in the serum (again prominently induced by the sub-therapeutic combination). Furthermore, nitric oxide synthase 3 (NOS3) and endothelin receptor type A (EDNRA) genes expression increased, but only in both combination groups and without significant differences between them. In the therapeutic dose groups, fluvastatin and valsartan decreased cholesterol values and systolic blood pressure. Sub-therapeutic doses of fluvastatin and valsartan are more effective in expressing cardiovascular pleiotropic effects than therapeutic doses of fluvastatin and/or valsartan. These results could be of significant clinical relevance. Copyright © 2017 Elsevier Inc. All rights reserved.

    To verify that the trabecular meshwork (TM) in the wall of the eyeball consists of smooth muscle fibers instead of collagen fibers or endothelial cells. Eighteen fresh eyeballs from 3 rabbits, 3 SD rats and 3 mice were sectioned along the sagittal plane and sliced after paraffin embedding for HE staining, VG staining, Masson staining, α-SMA immunohistochemistry or CD31 immunohistochemistry. These slices were observed under microscope and the structure of the TM was compared with those of scleral collagen fibers, ciliary muscles and endothelial cells. HE staining of the eyeball slices from the 3 animal species resulted in purplish red staining of the TM, which was highly consistent with ciliary muscle fibers. The cell?like structures on the surface of the TM were not clearly outlined, with flat nuclei showing a dark purple staining; these structures did not show obvious boundaries from the TM. Ciliary muscle fibers, which were smooth muscle cells in nature, were aligned in bundles in various directions. The longitudinally sectioned cells were flat and contained purplish cytoplasm and highly flattened nuclei. Scleral collagen fibers were stained dark red with a few fibroblasts sandwiched among them. The long axis of the fibroblasts was in parallel with that of the collagen fibers. The outline of the fibroblast was not clear and the nucleus was flat in dark blue. The vascular endothelial cells presented with different morphologies and contained light purplish cytoplasm and dark nuclei, protruding into the vascular cavity. VG staining of the TM revealed a pale red filamentous structure, and the collagen fibers were stained bright red. Masson staining of the TM showed a reticular structure consisting mainly of dark red fibers intermingled with thin green fibers. Scleral collagen fibers presented with a cord?like green wavy structure. The endothelial cells were green and flat, while the ciliary smooth muscle fibers were purple. In immunohistochemistry for α?SMA, the TM

    Emission spectroscopy, are already well-established instrumental analytical technique, has in recent years known important developments. Two mains factors are responsible; firstly the demands of metallurgy for purer and purer materials or alloys which are increasingly complex and difficult to analyse by chemical means; secondly, progress in optics, especially in the production of gratings, and in electronics in the field of photomultiplier tubes. We will not here catalogue all the new applications and methods, but we will consider a few amongst the most representative outside the conventional field. (author) [French] La spectroscopie d'emission, technique analytique instrumentale deja ancienne, a pris, depuis quelques annees, une extension notable. Deux facteurs principaux ont contribue a ce succes: d'une part, l'exigence de la metallurgie en materiaux de plus en plus pur ou en alliages de plus en plus complexes, difficiles a analyser chimiquement, d'autre part, les progres realises en optique, principalement dans la fabrication des reseaux, et en electronique dans le domaine des tubes photomultiplicateurs. Nous ne ferons pas ici le recensement de toutes les applications ou methodes nouvelles, mais nous en choisirons quelques unes des plus representatives hors du domaine classique. (auteur)

    Aim. - The U.M.R. 484 I.N.S.E.R.M. develops a 'cartilage imaging strategy' with the {sup 99m}Tc-N.T.P. 15-5 tracer that selectively binds to cartilage proteoglycans, allowing a highly specific cartilage imaging. Since chondro-genic tumours are characterized by the presence of cartilaginous matrix, we hypothesized that the {sup 99m}Tc-N.T.P. 15-5 tracer would allow chondrosarcoma imaging, which is currently lacking in clinics. In the rat model of grade II para-tibial chondrosarcoma, we evaluated the relevance of {sup 99m}Tc-N.T.P. 15-5 imaging for an early and specific diagnosis of chondrosarcoma. Methods. - {sup 99m}Tc-N.T.P. 15-5 longitudinal imaging of animals was performed during two months after para-tibial ortho-topic tumour implantation in the right paw, the left being used as control. At regular intervals, animals were submitted to {sup 99m}Tc-M.D.P. bone imaging, the only examination used for SPECT diagnosis of chondrosarcoma in patients. Tumour volume was monitored for two months when the tumours became palpable, with the two perpendicular diameters measured. For both cartilage and bone imaging, the scans were considered positive when areas of tracer uptake were present at sites consistent with the sites of inoculation. For each animal, positive scans were analyzed at each stage using the semiquantitative method of the target to background ratio (T.B.R.), with the target R.O.I. being delineated over the tumour and background R.O.I. over vertebra and muscle. T.B.R. time-course was followed as a function of tumour growth.At study ending, each animal was sacrificed for histopathological control. Results. - {sup 99m}Tc-N.T.P. 15-5 scans were positive in 100% of the animals at very early stage (three days) after implantation, while no palpable nor measurable tumour could be assessed. Quantitative analysis of {sup 99m}Tc-N.T.P. 15-5 scans evidenced a significant uptake of the tracer at the implantation site at early stage. The time-course of T

    Studies of the COMET core catcher concept developed for a future PWR have been continued. The concept is based on the spreading of a core melt on a sacrificial layer and its erosion, until a subsequent addition of water from below causes a fragmentation of the melt. A porous solidification of the melt would then admit a complete flooding within a short period. (orig.)

    This essay discusses the complex relation between the knowledges and practices of the researcher and his/her informants in terms of lateral concepts. The starting point is that it is not the prerogative of the (STS) scholar to conceptualize the world; all our “informants” do it too. This creates...... the possibility of enriching our own conceptual repertoires by letting them be inflected by the concepts of those we study. In a broad sense, the lateral means that there is a many-to-many relation between domains of knowledge and practice. However, each specific case of the lateral is necessarily immanent...... to a particular empirical setting and form of inquiry. In this sense lateral concepts are radically empirical since it locates concepts within the field. To clarify the meaning and stakes of lateral concepts, we first make a contrast between lateral anthropology and Latour’s notion of infra-reflexivity. We end...

      Concept theory is an extremely broad, interdisciplinary and complex field of research related to many deep fields with very long historical traditions without much consensus. However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge...... organizing systems (e.g. classification systems, thesauri and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe......, evaluate and use such systems. Based on "a post-Kuhnian view" of paradigms this paper put forward arguments that the best understanding and classification of theories of concepts is to view and classify them in accordance with epistemological theories (empiricism, rationalism, historicism and pragmatism...

  7. Nouvelles Techniques d'Intervention sur la Corrosion des Armatures du Béton Armé

    CERN Document Server

    Colloca, C

    1999-01-01

    Les principaux dégâts constatés dans les armatures passives du béton armé sont la corrosion généralisée et la corrosion locale. Ces dégradations sont provoquées soit par la carbonatation du béton soit par le contact avec l'eau pure ou l'eau chargée de chlorures pénétrant dans les pores et dans les fissures de surface. Ce document présente de nouvelles techniques d'intervention, fondées sur d'anciens principes, introduites pour le traitement électrochimique des zones altérées liées aux différentes conditions. La réalcalinisation (dans le cas de béton carbonaté) permet d'augmenter le pH du béton et de rétablir un niveau de basicité garantissant la passivation de l'armature. La désalification (dans le cas de béton entamé par les chlorures) provoque l'élimination des ions chlorure à travers la surface du béton. Les avantages de ces traitements, par rapport aux anciennes techniques, sont appréciables si l'on considère la durée d'exécution et leur coût moins élevé.

  11. Déserts alimentaires à Winnipeg (Canada : une nouvelle méthodologie de mesure d'un concept complexe et controversé

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Introduction : Les « déserts alimentaires » ont vu le jour dans les 20 dernières années et forment des secteurs préoccupants pour les collectivités, les autorités en santé publique et les chercheurs en raison de leur effet négatif possible sur la qualité de l’alimentation et en raison de leurs conséquences sur la santé. Ce sont des espaces résidentiels, habituellement en milieu urbain, où les résidents à faible revenu n’ont que peu ou pas accès à des établissements de vente au détail d'aliments qui offrent suffisamment de variété à un prix abordable. La recherche sur les déserts alimentaires présente des défis méthodologiques, notamment la façon de repérer et de classer les magasins d’alimentation au détail, la définition de la population à faible revenu ainsi que les paramètres concernant le transport et la proximité. De plus, les méthodes complexes qui sont souvent employées dans la recherche sur les déserts alimentaires peuvent être difficiles à reproduire et à communiquer aux principaux intervenants. Pour surmonter ces difficultés, nous avons voulu montrer qu’on pouvait concevoir une méthode simple et reproductible pour repérer les déserts alimentaires, à l’aide de données facilement accessibles en contexte canadien. Méthodologie : Cette étude a été menée à Winnipeg (Canada en 2014. Les établissements de vente au détail des aliments ont été trouvés à l’aide des Pages Jaunes et vérifiés par des diététistes en santé publique. Nous avons créé deux scénarios sur les déserts alimentaires en fonction de l’emplacement de la population à quintile de revenu le plus faible : a celle qui habitait à 500 m ou plus d’une épicerie appartenant à une chaîne nationale et b celle qui habitait à 500 m ou plus d’une épicerie appartenant à une chaîne nationale ou d’une épicerie à service complet. Résultats : En fonction du scénario utilisé, 64 574 ou 104 335 résidents à faible revenu vivaient dans un désert alimentaire. Conclusion : Les déserts alimentaires touchent une proportion importante de la population de Winnipeg et, même s’ils sont concentrés en centre-ville, ils sont présents également en banlieue. La méthodologie employée pour repérer les déserts alimentaires est accessible, claire et reproductible. Elle est utilisable pour exercer une surveillance périodique à faible coût, ainsi que pour favoriser un engagement significatif de la part des collectivités, des magasins de détail et des responsables des politiques.

    Full Text Available L'étude multichronique de photographies aériennes révèle que le lido entre Leucate et Port-la-Nouvelle (Aude a progradé d'environ 15 % en largeur, entre 1952 et 2008. L'analyse sédimentologique permet de montrer que cette progradation exceptionnelle en période d'élévation du niveau marin est due à la présence de barres pré-littorales volumineuses et bien alimentées par la dérive littorale et le transport éolien effectué par les vents de terre. Cependant, du fait de la montée actuelle du niveau marin (2,5 à 3 mm/an et malgré la poursuite de l'accrétion, le lido subit des inondations de plus en plus fréquentes entre le cordon actuel et l'ancien cordon romain.A kinematic study of vertical aerial photos taken between 1952 and 2008 reveals that the Leucate-Port-la-Nouvelle lido (Aude has prograded of about 15 % in width. A sedimentological analysis allows us to explain this accretion caused by drift and wind which supply abundant nearshore bars. In spite of this progradation, frequent floodings, favoured by sea level rise (2.5 to 3 mm-1.year, occur between the present coastal bar and the Roman barrier.

Après une présentation succincte des controverses dont fait l’objet le concept de développement durable à l’échelle mondiale, nous tenterons de préciser les enjeux de durabilité dans le contexte de la Nouvelle-Calédonie. L’entrée privilégie les articulations entre les trois dimensions de la durabilité, en s’appuyant sur les formes localement perçues de la performance économique, de l’intégrité de l’environnement et de l’équité sociale. Pour illustrer ces enjeux, nous nous intéressons plus précisément à la gestion sociale des impacts d’un important projet industriel d’extraction et de traitement du nickel dans la province Nord de Nouvelle-Calédonie. L’article décrit ensuite les principes à respecter pour la mise en place d’un suivi évaluation concerté entre les différents acteurs, susceptible de faciliter la prise en charge de cette transversalité et la gestion sociale des impacts du projet. Nous partons pour cela des acquis d’un programme de recherche portant sur l’élaboration d’une méthode de suivi évaluation participatif des programmes de développement local en province Nord. Enfin, nous insisterons sur les contraintes à l’efficacité et à la pérennité de dispositifs réellement participatifs, mais aussi à l’application des principes du développement durable, notamment dans le contexte du Pacifique insulaire.The aim of this article is to investigate the conditions and the interests of a participatory reflexion on the sustainable development and its consequences to draw up and to assess development policies.

    Full Text Available Annie Ernaux, considérée comme l’une des femmes écrivaines les plus célèbres du XXIe siècle, a exprimé l’angoisse commune de son âge et de son passé en rédigeant Les Années. Elle n’avait pas non seulement le but de décrire sa vie, mais aussi d’esquisser l’histoire de la société française à laquelle elle appartient. Lorsqu’elle est venue au monde en 1940, le monde était au seuil de la Seconde Guerre mondiale. Etant élevée dans cette atmosphère chaotique, elle a appris beaucoup de choses de sa société, de sa famille et de son environnement. Annie Ernaux a découvert le monde comme une jeune fille, une mère, une épouse et une grand-mère. Ses expériences sociales et familiales l’ont beaucoup mûrie et elle a commencé à rédiger ses pensées. Ses souvenirs ont fait partie de ses écritures autobiographiques. Dans Les Années, Annie Ernaux a profité de toutes ses expériences personnelles et sociales avec de différents moyens. Elle a essayé d’établir des liens entre l’histoire de sa vie et celle de la société. Elle a accordé une importance à la vie sociale plutôt que sa propre vie dans Les Années. Elle y a développé des propres techniques d’écriture en se servant des photos familiales et personnelles, d’un film, d’une vidéo, des marques de publicité, des chansons, d’un tableau, des notes de journal ainsi que des événements sociologiques et historiques. Elle a ainsi créé une nouvelle forme d’autobiographie : autobiographie impersonnelle.

Su evidente atractivo entre los lectores ha hecho que algunos padres, educadores y profesionales del ámbito de la promoción de la lectura se plantearan el por qué de dicha afición, llegando a conclusiones erróneas como la creencia de que se trata de una lectura menor, dirigida esencialmente a la pura distracción de quien los lee. El manga, en concreto, es el género dentro del cómic que más se consume en occidente. Se ha convertido en un fructífero producto de mercado que deriva en videojuegos, series de televisión, películas de cine… Su gran acogida entre el público infantil y juvenil preocupa a mediadores por la supuesta carga violenta y sexual y la baja calidad literaria de sus obras.

    This classic text, aimed at senior undergraduates and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depth to give the reader a quantitative understanding of the subject. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail: it provides a series of astrophysical sketches. For this fourth edition, nearly every part of the text has been reconsidered and rewritten, new sections have been added to cover recent developments, and others have been extensively revised and brought up to date. The book begins with an outline of the scope of modern astrophysics and enumerates some of the outstanding problems faced in the field today. The basic physics needed to tackle these questions are developed in the next few chapters using specific astronomical processes as examples. The second half of the book enlarges on these topics and shows how we can obtain quantitative insight into the structure and evolution of...

    Full Text Available Après avoir montré l'importance des réserves de pétrole non conventionnel et l'enjeu que représente pour l'humanité la mise en exploitation de ces ressources, cette étude examine les axes actuels de recherches et l'état de la technologie pour chacune des sources de nouveau pétrole retenues : mers profondes, récupération assistée, huiles lourdes et sables asphaltiques, schistes bitumineux et conversion du charbon. Il en ressort que si les ressources de nouveau pétrole sont considérables, leur mise en valeur nécessitera des investissements très lourds, et le coût du pétrole ainsi produit restera élevé, comparé au coût actuel du pétrole conventionnel. Compte tenu des délais de mise en oeuvre, des problèmes technologiques restant à résoudre et de la nécessité de réaliser des pilotes semi-industriels très coûteux pour expérimenter les nouvelles techniques, il convient de consentir sans attendre un effort important de recherche technologique, impliquant un accroissement sensible des budgets de R&D, mais aussi des incitations financières appropriées. Cet effort de mise au point de technologies adaptées à ces sources d'hydrocarbures sera favorisé par les nouvelles conditions économiques créées par la rareté relative des réserves d'hydrocarbures classiques, à condition que les Etats, par leur politique, favorisent la production de ressources d'hydrocarbures à coût élevé. A l'heure actuelle, on peut évaluer la production de pétrole difficile à environ 100 Mt, l'essentiel étant réalisé dans le domaine des huiles lourdes et de la récupération assistée ; on estime que la production de nouveau pétrole pourrait représenter 200 à 350 Mt en 1990 et se situer entre 600 et 900 Mt en 2000, soit 5 à 8 % de la production de pétrole en 1990 et 15 à 20 % en 2000. Un tel objectif nécessiterait des investissements de l'ordre de 500 à 750 milliards de dollars 1980. After pointing out the importance of

    Physical theories are commonly classified as being either ''classical'' or ''modern''. The reasons for this distinction are both historical and substantive. Limited in the sophistication of their measuring instruments, early scientists proposed theories appropriate for the description of the simplest and most accessible physical phenomena, e.g., the trajectories of the planets. Because of the class of phenomena observed, certain beliefs came to underlie all classical theories with regard to the nature of time, space, matter, etc. For example, the idea was undisputed that an object has at all times both a definite position and velocity. Not until the interior of the atom and the nature of electromagnetic radiation were explored was it discovered that the concepts of classical physics are inadequate to deal with many phenomena. A reassessment of fundamental postulates led to the formulation of modern physics which, it is believed, successfully treats the behavior of all physical systems. To gain an understanding of the rudiments of modern physics, one proceeds as the early scientists did by first mastering the classical concepts that emerge from their intuitive picture of the world. Modifications of these concepts are subsequently introduced which allow a more accurate treatment of physical phenomena, particularly atomic and nuclear systems

The short story entitled The Vulture Master presents us, from within a traditional narrative structure, with a modern fantasy tale blending in realism, symbolism and poetry, and where the writer deals in his own way with such contemporary literary themes as disenchantment, perpetual captivity, and the duality of dream and reality. Drawing his inspiration from language itself, oral practices, beliefs and popular imagery, the writer, seeking to set his tale firmly in Yemeni reality, manages to transfigure this modern existential experiment.

    The main intention of this book is to describe and develop the conceptual, structural and abstract thinking of mathematics. Specific mathematical structures are used to illustrate the conceptual approach; providing a deeper insight into mutual relationships and abstract common features. These ideas are carefully motivated, explained and illustrated by examples so that many of the more technical proofs can be omitted. The book can therefore be used: ·         simply as an overview of the panorama of mathematical structures and the relations between them, to be supplemented by more detailed texts whenever you want to acquire a working knowledge of some structure ·         by itself as a first introduction to abstract mathematics ·         together with existing textbooks, to put their results into a more general perspective ·         to gain a new and hopefully deeper perspective after having studied such textbooks Mathematical Concepts has a broader scope and is less detaile...

Assimilables à « l’hypersollicitation par le client » comme il a été repéré par Christophe Dejours, ces formes ont été observées lors d’une enquête menée récemment sur la conciliation entre la vie privée et la vie professionnelle dans sept organisations montréalaises. La recherche qualitative a recueilli en tout le discours de 88 répondants distribués également selon le sexe et exerçant des fonctions liées au génie informatique. Ces observations permettent d’envisager une nuance au modèle théorique de la santé mentale ci-haut mentionné, visant à tenir compte des effets délétères d’une très grande latitude décisionnelle assortie de très grandes responsabilités chez des travailleurs hautement qualifiés.Are there distinct mental health problems among workers in the new economy?

    Full Text Available From the mid-19th century, vast improvements in steamship and communication technology created an interlinked network of port-cities in the Indian Ocean and maritime Asia. Though Rangoon and Penang had starkly different relationships to colonial rule, they shared a lineage as multi-ethnic ports where various communities had existed side-by-side for centuries. The advent of the Victorian era fostered new class and racial divisions between them, yet also created a new feuilleton culture in the port-city with the mushrooming of newspapers, books, and a new reading public. Diverse ethnic and linguistic communities sought platforms to articulate their concerns and inform themselves of the affairs of the world, and their place within it. Burmese in Rangoon, imbued with a renewed sense of cultural pride, absorbed the rising tide of anticolonialism nationalism echoing throughout the world. Penangites transformed their society using the liberal, cosmopolitan tenants of imperial citizenship to make political and cultural claims for a multi-ethnic society. The vibrant, outward-looking atmosphere of the colonial port-city as a node of information and cultural exchange made Penang and Rangoon the intellectual staging grounds for new visions of the nation.À compter du milieu du xixe siècle, d’importantes améliorations dans la navigation à vapeur et les technologies des communications ont créé un réseau de villes portuaires dans l’Océan indien et l’Asie maritime. Même si Rangoon et Penang avaient des relations divergentes avec la puissance coloniale, elles participaient d’un type identique comme ports où cohabitaient depuis des siècles des communautés d’ethnies différentes. L’ère victorienne conduisit à de nouvelles divisions sociales et ethniques, mais suscita dans la ville portuaire une nouvelle culture littéraire avec le foisonnement des journaux, des livres et un nouveau lectorat.

    This report describes a new method for dosing uranium in biological media based on measurement of alpha activity. After treatment of the sample with a mineral acid, the uranium is reduced to the valency four by trivalent titanium and is precipitated as phosphate in acid solution. The uranium is then separated from the titanium by precipitation as UF{sub 4} with lanthanum as carrier. A slight modification, unnecessary in the case of routine analyses, makes it possible to eliminate other possible alpha emitters (thorium and transuranic elements).

The systems are differentiated by their mode of action, according to the engine type to be depolluted (two-stroke, four-stroke, diesel or spark-ignition, and by their type of make-up. The major developments foreseen in the future, in view of compliance with the new legislations, are described. It is shown that some prototype vehicles with internal combustion engines are able to emit pollutant quantities really close to zero, such as electric cars.

    Full Text Available The Project "Communal Forestry Development in the Bolivian Highlands (Altiplano " : a New Vision of the Communautary Agroforestry. Since 1991, the "Communal Forestry Development in the Bolivian Highlands (Altiplano " project has been promoting self-supporting agroforestry activities, integrated into the farmerproductive system, boosting the satisfaction of needs in forest products, increasing agriculture production and conserving natural resources. High demands on land and the difficult climatic conditions prevailing in Potosi department, where the project is located, are serious constraints to a massive forestation. Taking these constraints into account, the project has developped a strategy, the Communal Forestry Development, which is focussed on an integrated and participative approach : "integrated" means the technical available alternatives, including agroforestry actions (promotion of forester, fruit, and forrage trees and shrubs as well as hydraulic and soil conservation actions, are implemented inside the productive agro-sylvo-pastoral systems. Within the scope of an implication of the stakeholders, the project uses "participative" ways as communautary planning of agroforestry priorities. Those objectives are reached by means of training, extension and communication. Another orientation consists in a flexible coordination with all the organizations working on the field. The project is now implementing a second phase. The results which have been registered so far lead towards a strenghthening of integrated actions and increasing responsabilities of as well communities as other institutions. Such an orientation points out the necessity of a long-term and flexible project conception.

    Cancer is a multi-etiologic, multistage disease with a prevalent genetic component, which happens when a large number of genes, critical for cell growth, death, differentiation, migration, and metabolic plasticity are altered irreversibly, so as to either 'gain' (oncogenes) or 'lose' (tumour suppressors) their function. Recent discoveries have revealed the previously underestimated etiologic importance of multiple epigenetic, that is to say, reversible factors (histone modifications, DNA methylation, non-coding RNA) involved in the transcriptional and post-transcriptional regulation of proteins, indispensable for the control of cancerous phenotype. Stable alterations of epigenetic machinery ('epi-mutations') turn out to play a critical role at different steps of carcinogenesis. In addition, due to substantial recent progress in stem cell biology, the new concept of cancer stem cells has emerged. This, along with newly discovered epigenetic cancer mechanisms, gives rise to a hope to overcome radio- and chemo-resistance and to eradicate otherwise incurable neoplasms. (authors)

    Bonhivers, Jean-Christophe

    is the first that considers the analysis of these degradations. The fundamental mechanism to reduce the heat consumption in an existing network has been made explicit; it is the basis of the developed method. The Bridge Method includes the definition of "a bridge", which is a set of modifications leading to heat reduction in a heat exchanger network. It is proven that, for a given set of streams, only bridges can lead to heat savings. The Bridge Method also includes (1) a global procedure for heat exchanger network retrofit, (2) a procedure to enumerate systematically the bridges, (3) "a network table" to easily evaluate them, and (4) an "energy transfer diagram" showing the effect of the two first principles of thermodynamics of energy conservation and degradation in industrial processes in order to identify energy savings opportunities. The Bridge Method can be used for the analysis of networks including several types of heat transfer, and site-wide analysis. The Bridge Method has been applied in case studies for retrofitting networks composed of indirect-contact heat exchangers, including the network of a kraft pulp mill, and also networks of direct-contact heat exchangers, including the hot water production system of a pulp mill. The method has finally been applied for the evaluation of a biorefinery process, alone or hosted in a kraft pulp mill. Results show that the use of the method significantly reduces the search space and leads to identification of the relevant solutions. The necessity of a bridge to reduce the inputs and outputs of a process is a consequence of the two first thermodynamics principles of energy conservation and increase in entropy. The concept of bridge alone can also be used as a tool for process analysis, and in numerical optimization-based approaches for energy integration.

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available Le mouvement dit de « RSE » entend concilier l’actuel mode d’accumulation à dominante financière avec certaines exigences sociales et environnementales. Or, ce mouvement s’inscrit assez bien dans l’analyse historique et institutionnaliste que Karl Polanyi a faite des limites de la marchandisation du monde. En effet, ce mouvement consiste à revenir sur la trop forte marchandisation du rapport à la nature et au travail qu’aurait entraîné le développement d’un capitalisme financiarisé. En réaction, ce mouvement mobilise l’engagement volontaire des entreprises pour bâtir une nouvelle « grande transformation », c’est-à-dire une forme inédite d’articulation entre le juste et l’efficace visant à assurer la viabilité du capitalisme. Cela revient à élargir l’engagement économique à autre chose que la simple maximisation des intérêts individuels de court terme. Cet article vise à exploiter cette proximité entre le mouvement de la RSE et l’analyse polanyienne de la marchandisation, proximité selon nous fructueuse et qui n’a jamais fait l’objet d’une analyse systématique. L’enjeu est de déterminer dans quelle mesure la RSE constitue aujourd’hui une réponse pertinente à la nécessaire gestion collective de la fiction que constitue la marchandisation apparente de la monnaie, de la terre et du travail.The movement says about "CSR" tries to reconcile the current financial mode of accumulation with certain social and environmental requirements. This movement joins well enough in the historic and institutionnalist analysis which Karl Polanyi made of the limits of marchandisation of the world. Indeed, this movement consists in returning on excess strong marchandisation of the relationship with the nature and with the work which would have pulled the new capitalism. In reaction, this movement mobilizes the individual commitment to build a new "great transformation", that is new articulation

Le présent article s’évertue à montrer les mouvements marquant l'évolution de la poésie arabe en Israël, dans un contexte contradictoire. Il souligne trois tendances principales. La première, explicitement militante, développée dans le giron de la Rakah, parti communiste israélien. Destinée à un public particulier et animée par une idéologie de combat, elle sacrifie parfois la poétique au profit de la politique. La deuxième tendance semble d'une nouvelle esthétique poétique basée sur l'individualité et l'expérience personnelle. La troisième voix poétique, profondément intimiste, est représentée par la poétesse Nida Khoury. Son approche de la résistance et du militantisme, ainsi que son approche originale de la langue révèle la profondeur d'une déchirure personnelle et la finesse d'un engagement subtilement exprimé.Enfin, le tiraillement intérieur entre deux appartenances et la recherche identitaire constituent l'un des principaux thèmes qui unissent les poètes de ces trois tendances.The present article focuses on showing the movements marking the evolution of Arabic poetry in Israel in a conflicting context.

    This research is aimed to analyse students’ conceptions on several electricity concept. This is a descriptive research with the subjects of new students of Sebelas Maret University. The numbers of the subject were 279 students that consisted of several departments such as science education, physics education, chemistry education, biology education and mathematics education in the academic year of 2017/2018. The instrument used in this research was the multiple-choice test with arguments. Based on the result of the research and analysis, it can be concluded that most of the students still find misconceptions and do not understand electricity concept on sub-topics such as electric current characteristic in the series and parallel arrangement, the value of capacitor capacitance, the influence of the capacitor charge and discharge towards the loads, and the amount of capacitor series arrangement. For the future research, it is suggested to improve students’ conceptual understanding with appropriate learning method and assessment instrument because electricity is one of physics material that closely related with students’ daily life.

  15. Clinical reasoning: concept analysis.

    Science.gov (United States)

    Simmons, Barbara

    2010-05-01

    This paper is a report of a concept analysis of clinical reasoning in nursing. Clinical reasoning is an ambiguous term that is often used synonymously with decision-making and clinical judgment. Clinical reasoning has not been clearly defined in the literature. Healthcare settings are increasingly filled with uncertainty, risk and complexity due to increased patient acuity, multiple comorbidities, and enhanced use of technology, all of which require clinical reasoning. Data sources. Literature for this concept analysis was retrieved from several databases, including CINAHL, PubMed, PsycINFO, ERIC and OvidMEDLINE, for the years 1980 to 2008. Rodgers's evolutionary method of concept analysis was used because of its applicability to concepts that are still evolving. Multiple terms have been used synonymously to describe the thinking skills that nurses use. Research in the past 20 years has elucidated differences among these terms and identified the cognitive processes that precede judgment and decision-making. Our concept analysis defines one of these terms, 'clinical reasoning,' as a complex process that uses cognition, metacognition, and discipline-specific knowledge to gather and analyse patient information, evaluate its significance, and weigh alternative actions. This concept analysis provides a middle-range descriptive theory of clinical reasoning in nursing that helps clarify meaning and gives direction for future research. Appropriate instruments to operationalize the concept need to be developed. Research is needed to identify additional variables that have an impact on clinical reasoning and what are the consequences of clinical reasoning in specific situations.

The combined concept has the advantage of immediately providing, if required, intervention levels for the various measures to be taken, and of obliging those persons concerned with emergency protection to study and quantify, already at the planning stage, the influence of a range of accident conditions on the decision on measures. In this context, the use of computerized decision support systems which are currently being developed is indispensable. (orig./DG) [de

    The concept of radiation promotion was proposed in this study. The proposal of this concept was dependent upon stimulation in growth weight of survived chicks when fertile eggs were exposed to 60 Co gamma radiation. It was found that female chick (Promotive Sex) responded to this proposal concept rather than the male. Moreover, the dose level of 640 rads was found to be the Promotive Dose. It is important before applying ionizing radiation as a growth promotive to take into consideration whether you want increasing egg or meat production, as meat promotion in layers breed is bound to decrease egg production.

    2016-12-01

    Full Text Available L’enseignement supérieur traditionnel est essentiellement basé sur la transmission du savoir et occasionnellement sur celle du savoir-faire. Il se réclame donc des disciplines universitaires (mathématiques, physique, chimie, géologie.... dispensées dans les universités et grandes écoles. Or, la réussite professionnelle et sociale dans le monde moderne exige d’autres acquis plus probants que des connaissances pures. Plusieurs recherches récentes ont ainsi montré que la résolution de bien des problèmes requiert des qualités pragmatiques d’efficacité indispensables pour l’accomplissement d’un travail créatif. Résoudre un problème revient alors à apprendre à maitriser une démarche méthodique composée de plusieurs phases, depuis l’identification du problème jusqu’à sa solution finale en passant par l’analyse judicieuse des causes. Il faut également maîtriser l’utilisation d’outils conceptuels et Méthodologiques tels que, entre autres, la « loi de Pareto », le questionnement systématique et le brainstorming . Au Vietnam on peut espérer la mise en application de ces nouvelles orientations dans un enseignement supérieur qui doit absolument se fixer comme objectif d’améliorer la qualité du travail social pour répondre aux nouvelles exigences de développement du pays.

    1998-01-01

    The 'technological conception' examines how a project can be concretized or how it is possible to 'conceive', i.e. to produce operative ideas that can be directly use. The first part of this book, called 'concepts and methods', analyzes the logics of conceiving and its philosophy in the construction of its objects and in the management of its programs or projects. The second part is devoted to some exemplary technologies: roads, tunnels, bridges, dams, nuclear power plants, aerospace constructions, and analyzes different concrete logics of technological conception. Finally, the author shows how todays conception faces the risks and complexity increase of systems and considers the possibility of an entirely automated manufacturing shop in the future. (J.S.)

  14. Assessment of fuel concepts

    International Nuclear Information System (INIS)

    Bailey, W.J.; Barner, J.O.

    1978-01-01

    The relative merits of various LWR UO 2 fuel concepts with the potential for improved power-ramping capability were qualitatively assessed. In the evaluation, it was determined that of the various concepts being considered, those that presently possess an adequately developed experience base include annular pellets, cladding coated with graphite on the inner surface, and packed-particle fuel. Therefore, these were selected for initial evaluation as part of the Fuel Performance Improvement Program. For this program, graphite-coated cladding is being used in conjunction with annular pellet fuel as one of the concepts with the anticipation of gaining the advantage of the combined improvements. The report discusses the following: the criteria used to evaluate the candidate fuel concepts; a comparison of the concepts selected for irradiation with the criteria, including a general description of their experience bases; and a general discussion of other candidate concepts, including identifying those which may be considered for out-of-reactor evaluation as part of this program, those for which the results of other programs will be monitored, and those which have been deleted from further consideration at this time

  15. Nouvelles approches en theorie du champ moyen dynamique: le cas du pouvoir thermoelectrique et celui de l'effet orbital d'un champ magnetique

    Science.gov (United States)

    Arsenault, Louis-Francois

    , cette approche donne une bonne representation de S lorsque le systeme devient coherent. Les calculs montrent aussi que la formule Kelvin est precise lorsque la fonction spectrale des electrons devient incoherente, soit a plus haute temperature. Dans la limite Kelvin, S est essentiellement l'entropie par particule, tel que propose il y a longtemps. Nos resultats demontrent ainsi que la vision purement entropique de S est la bonne dans le regime incoherent, alors que dans le regime coherent, l'approche a frequence infinie est meilleure. Nous avons utilise une methode a la fine pointe, soit le Monte-Carlo quantique en temps continu pour resoudre la DMFT. Pour permettre une exploration rapide du diagramme de phase, nous avons du developper une nouvelle version de la methode des perturbations iterees pour qu'elle soit applicable aussi a forte interaction au-dela de la valeur critique de la transition de Mott. Un autre sujet a aussi ete aborde. L'effet orbital du champ magnetique dans les systemes electroniques fortement correles est une question tres importante et peu developpee. Cela est d'autant plus essentiel depuis la decouverte des oscillations quantiques dans les supraconducteurs a haute temperature (haut- Tc). Par desir de developper une methode la moins biaisee possible, nous avons derive la DMFT lorsqu'un champ se couplant a l'operateur energie cinetique par la substitution de Peierls est present. Ce type d'approche est necessaire pour comprendre entre autres l'effet de la physique de Mott sur des phenomenes tels que les oscillations quantiques. Nous avons obtenu un resultat tres important en demontrant rigoureusement que la relation d'auto-coherence de la DMFT et le systeme intermediaire d'impurete quantique restent les memes. L'effet du champ peut etre contenu dans la fonction de Green locale, ce qui constitue la grande difference avec le cas habituel. Ceci permet de continuer a utiliser les solutionneurs d'impuretes standards, qui sont de plus en plus puissants

  16. Teamwork: a concept analysis.

    Science.gov (United States)

    Xyrichis, Andreas; Ream, Emma

    2008-01-01

    This paper is a report of an analysis of the concept of teamwork. Teamwork is seen as an important facilitator in delivering quality healthcare services internationally. However, research studies of teamwork in health care are criticized for lacking a basic conceptual understanding of what this concept represents. A universal definition for healthcare settings and professionals is missing from published literature. Walker and Avant's approach was used to guide this concept analysis. Literature searches used bibliographic databases (Medline, CINAHL, Web of Science, Proquest CSA), internet search engines (GoogleScholar), and hand searches. Literature published between 1976 and 2006 was reviewed but only material in English was included. Based on the analysis undertaken, teamwork is proposed as a dynamic process involving two or more healthcare professionals with complementary backgrounds and skills, sharing common health goals and exercising concerted physical and mental effort in assessing, planning, or evaluating patient care. This is accomplished through interdependent collaboration, open communication and shared decision-making, and generates value-added patient, organizational and staff outcomes. Praising the value of teamwork without a common understanding of what this concept represents endangers both research into this way of working and its effective utilization in practice. The proposed definition helps reconcile discrepancies between how this concept is understood by nurses and doctors, as well as allied health professionals. A common understanding can facilitate communication in educational, research and clinical settings and is imperative for improving clarity and validity of future research.

    2016-01-01

    Down through the ages, music has been universally valued for its therapeutic properties based on the psychological and physiological responses in humans. However, the underlying mechanisms of the psychological and physiological responses to music have been poorly identified and defined. Without clarification, a concept can be misused, thereby diminishing its importance for application to nursing research and practice. The purpose of this article was for the clarification of the concept of music therapy based on Walker and Avant's concept analysis strategy. A review of recent nursing and health-related literature covering the years 2007-2014 was performed on the concepts of music, music therapy, preferred music, and individualized music. As a result of the search, the attributes, antecedents, and consequences of music therapy were identified, defined, and used to develop a conceptual model of music therapy. The conceptual model of music therapy provides direction for developing music interventions for nursing research and practice to be tested in various settings to improve various patient outcomes. Based on Walker and Avant's concept analysis strategy, model and contrary cases are included. Implications for future nursing research and practice to use the psychological and physiological responses to music therapy are discussed.

  18. Development of numerical concepts

    2013-06-01

    Full Text Available The development of numerical concepts is described from infancy to preschool age. Infants a few days old exhibit an early sensitivity for numerosities. In the course of development, nonverbal mental models allow for the exact representation of small quantities as well as changes in these quantities. Subitising, as the accurate recognition of small numerosities (without counting, plays an important role. It can be assumed that numerical concepts and procedures start with insights about small numerosities. Protoquantitative schemata comprise fundamental knowledge about quantities. One-to-one-correspondence connects elements and numbers, and, for this reason, both quantitative and numerical knowledge. If children understand that they can determine the numerosity of a collection of elements by enumerating the elements, they have acquired the concept of cardinality. Protoquantitative knowledge becomes quantitative if it can be applied to numerosities and sequential numbers. The concepts of cardinality and part-part-whole are key to numerical development. Developmentally appropriate learning and teaching should focus on cardinality and part-part-whole concepts.

    Dyess, Susan Macleod

    2011-12-01

    This paper reports a concept analysis of faith. There are numerous scholars who consider spirituality and religiosity as they relate to health and nursing. Faith is often implied as linked to these concepts but deserves distinct exploration. In addition, as nursing practice conducted within communities of faith continues to emerge, concept clarification of faith is warranted. Qualitative analysis deliberately considered the concept of faith within the lens of Margaret Newman's health as expanding consciousness. Data sources used included a secondary analysis of stories collected within a study conducted in 2008, two specific reconstructed stories, the identification of attributes noted within these various stories and selected philosophical literature from 1950 to 2009.  A definition was identified from the analysis; faith is an evolving pattern of believing, that grounds and guides authentic living and gives meaning in the present moment of inter-relating. Four key attributes of faith were also identified as focusing on beliefs, foundational meaning for life, living authentically in accordance with beliefs, and interrelating with self, others and/or Divine. Although a seemingly universal concept, faith was defined individually. Faith appeared to be broader than spiritual practices and religious ritual and became the very foundation that enabled human beings to make sense of their world and circumstances. More work is needed to understand how faith community nursing can expand the traditional understanding of denominationally defined faith community practices and how nurses can support faith for individuals with whom they encounter within all nursing practice. © 2011 Blackwell Publishing Ltd.

    There is an increasing need to reduce costs of offshore production facilities in order to make development of offshore fields profitable. For small fields with short production time there is in particular a need to investigate ways to reduce costs. The idea of platform reuse is for such fields particularly attractive. This paper will review reusable platform concepts and will discuss their range of application. Particular emphasis will be placed on technical limitations. Traditional concepts as jackups and floating production facilities will be discussed by major attention will be given to newly developed ideas for reuse of steel jackets and concrete structures. It will be shown how the operator for several fields can obtain considerable savings by applying such reusable platform concepts

This practice can be considered as the response found by the large companies to the problem of production costs that were in a continuous rising, concomitant with the rising of living standards and remuneration.This paper aims to analyze the concept of outsourcing in terms of its evolution, but also in terms of incentives, ups and downs associated with the concept. On the other hand, this paper seeks to capture the fundamentals of this concept veracity and whether it could be implemented in the public service.

  2. Communication, concepts and grounding.

    Science.gov (United States)

    van der Velde, Frank

    2015-02-01

    This article discusses the relation between communication and conceptual grounding. In the brain, neurons, circuits and brain areas are involved in the representation of a concept, grounding it in perception and action. In terms of grounding we can distinguish between communication within the brain and communication between humans or between humans and machines. In the first form of communication, a concept is activated by sensory input. Due to grounding, the information provided by this communication is not just determined by the sensory input but also by the outgoing connection structure of the conceptual representation, which is based on previous experiences and actions. The second form of communication, that between humans or between humans and machines, is influenced by the first form. In particular, a more successful interpersonal communication might require forms of situated cognition and interaction in which the entire representations of grounded concepts are involved.

    Albertazzi, Liliana; Canal, Luisa; Malfatti, Michela; Micciolo, Rocco

    2013-01-01

    The study shows a systematic naturally biased association between percepts and concepts. Specifically, it shows that a series of terms pertaining to an abstract semantic field (related to the frame of ethics in social behaviour) has a nonrandom, highly significant, association with colours (hues). This is the first time that consistent associations between abstract terms and colours have been reported in the general population. The main hypothesis, ie that there appear to be 'hues of concepts', was borne out by the results: the abstract terms considered were coloured with blue/green (ie cool) colours as well as their synonyms, while their antonyms were coloured with red/yellow (ie warm) colours. The association provides information about the nature of abstract concepts and their relationship with perception. It also sheds light on the interrelations among words in semantic domains that, to date, have been studied from only a computational viewpoint.

    This paper reports on concept in catalysis which are very important in heterogeneous catalysis, even today, when in spite of surface science, the complexity of events at a real catalytic surface is still evading the understanding necessary for design. In this paper the authors will attempt to give an update on evolving concepts in heterogeneous catalysis. The topics include: counting active centers on metal surfaces; the notion of turnover frequency for a catalytic cycle; the concept of structure (in) sensitive reactions; the ensemble (geometric) vs. The ligand (electronic) effect following Sachtler's school; the idea of a rate determining step and of a most abundant reactive intermediate; the effect of surface non-uniformity on catalytic kinetics; what makes catalytic cycles turnover

  6. Systemizing the Pedagogic Concepts

    2013-01-01

    Full Text Available The paper emphasizes the necessity of systemizing the pedagogic concepts to complement the pluralism principle dominating in pedagogy over the recent years. The author recommends the person oriented systematic synergetic methodology combining various research data into a holistic scientific approach. The paper regards education as the core pedagogic concept - including training, upbringing, self-education, their respective subcomponents, and generated personal resource. The elements of personal resource combine the acquired knowledge, skills and values, developed subjective attitudes and individual health data. The key pedagogic terms describing the educational process are represented by a three-level system; the first level involves the educational form concepts, the second – generated personal resource, the third – summarized notion system combining the previous levels and reflecting their binary relations. The given construct systemizes the pedagogic conceptual apparatus and clarifies the theoretical notion of personal education.

    How can those in the history of science, history of technology, and economics communicate more with each other than they are accustomed? How can they become more globally oriented? While these three disciplines today have more convergent interests than in the past, there is still a large potential for further exchange and involvement to explore and exploit. The contributors to this Focus section discuss a number of concepts that may serve as tools to bring these three disciplines more closely together and ease their evolution in a less Eurocentric direction. These concepts include trading zones, interaction and formalization, production, and machines and self-organization.

    Loneliness is a universal human experience recognized since the dawn of time, yet it is unique for every individual. Loneliness can lead to both depression and low self-esteem. This article explicates the concept of loneliness through the examination of its conceptual definition and uses, defining attributes, related concepts, and empirical referents. Literature review using hand search and database were used as sources of information. Because loneliness is commonly encountered in nursing situations, the information provided will serve as a framework for assessment, planning, intervention, and evaluation of clients.

    To analyze the concept of stress and provide an operational definition of stress. Literature review revealed that stress is a commonly used, but often ambiguous, term. Findings supported a definition of stress entailing an individual's perception of a stimulus as overwhelming, which in turn elicits a measurable response resulting in a transformed state. This analysis adopts a dynamic definition of stress that may serve to encourage communication, promote reflection, and enhance concept understanding. This definition may provide direction for future work, as well as enhance efforts to serve patients affected by stress. © 2013 Wiley Periodicals, Inc.

    1996-01-01

    There are principle drawbacks of any kind of solid nuclear fuel listed and analyzed in the first part of the paper. One of the primary results of the analyses performed shows that the solid fuel concept, which was to certain degree advantageous in the first periods of a nuclear reactor development and operation, has guided this branch of a utilization of atomic nucleus energy to a death end. On the background of this, the liquid fuel concept and its benefits are introduced and briefly described in the first part of the paper, too. As one of the first realistic attempts to utilize the advantages of liquid fuels, the reactor/blanket system with molten fluoride salts in the role of fuel and coolant simultaneously, as incorporated in the accelerator-driven transmutation technology (ADTT) being proposed and currently having been under development in the Los Alamos National Laboratory, will be studied both theoretically and experimentally. There is a preliminary design concept of an experimental assembly LA-O briefly introduced in the paper which is under preparation in the Czech Republic for such a project. Finally, there will be another very promising concept of a small low power ADTT system introduced which is characterized by a high level of safety and economical efficiency. In the conclusion, the overall survey of principal benefits which may be expected by introducing liquid nuclear fuel in nuclear power and research reactor systems is given and critically analyzed. 7 refs, 4 figs

    Self-esteem is an inner attitude at the base of the construction of personality and psychic balance in addition to be responsible of adaptive processes over the course of life. The concept of self-esteem is commonly used in several disciplines however, it seems that the consensus on its conceptualization and its operationalization is not yet reached. In this context, the concept analysis allows to address a phenomenon and to understand its use and its evolution from a unique disciplinary perspective. The aim of this article is therefore to analyze the concept of self esteem from a nursing perspective to identify : definitions of the term and related terms, attributes, model and limit cases proposed here within the community of mental health nurses, antecedents and consequents as well as the empirical references using the Walker and Avant method. The attributes identified allowing a deeper understanding of the concept are : the self-value, the self-acceptance, the self-efficacy, attitude towards oneself and finally, self-respect.

    Full Text Available La problématique de cet article porte sur le rôle de la coopération décentralisée dans le domaine de l’eau, dans la mesure où celle-ci semble pouvoir apporter des réponses concrètes au problème de l’accès universel à l’eau et constituer une nouvelle option pour la communauté internationale. Dans une première partie, on présentera les problèmes rencontrés par les différents modes de gestion de l’eau dans les pays en développement et la façon dont ils ont successivement tenté de satisfaire à certains objectifs bien précis (accès universel à l’eau, réduction des coûts, prise en compte des besoins prioritaires. Dans une deuxième partie, sur la base d’une initiative de coopération décentralisée entre le Conseil régional de Seine-Saint-Denis et la ville marocaine de Figuig, on s’interrogera sur les apports et limites de cette nouvelle forme de partenariat participatif afin d’en évaluer la pérennité ainsi que la « soutenabilité sociale », montrant, de ce fait, sa proximité avec l’économie solidaire.Our paper builds on this issue of decentralized cooperation in the field of water management. Cooperation between decentralized entities in order to ensure the access to safe drinking water for all now constitutes in many places a preferred water governance option. Therefore, in the first part, we will provide an overview of the current difficulties encountered by the various forms of water management in developing countries, showing the solutions that they successively brought to specific issues (access for all, cost reduction, priority needs. In the second part, we will address the particular case of decentralized cooperation between the General Council of Seine-Saint-Denis in the suburbs of Paris, France, in partnership with the city of Figuig in Morocco.

    Full Text Available « La Nouvelle Mosquée » est érigée, à la fin du xviie siècle, dans la seule perspective de doter le rite hanéfite de sa propre Grande Mosquée. Cette nouvelle édification relève, à l’évidence, d’une procédure collective exceptionnelle, celle qu’entreprend la milice d’Alger, en l’occurrence le corps des janissaires, en puisant dans les fonds des Subul al-Khayrât. L’examen du livre de comptes qu’avait tenu cette institution ḥabûs, responsable de la gestion de la plupart des mosquées hanéfites et de leurs awqâf, aussitôt après le lancement du chantier, a permis de suivre le déroulement des travaux sur une période de presque dix années, soit de 1067/1656-1657 à 1076/1665-1666. Ce rôle de chantier apporte des éclairages significatifs notamment sur la nature, la provenance, la quantité et le coût des matériaux employés à la construction. Ils ne manquent pas non plus de documenter les aspects concernant leur fabrication, voire leur préparation, et quelque rares fois leur mise en œuvre ; une mise en œuvre qui, ici, revient à la dextérité de nombreux hommes, mobilisés dans le cadre corporatif. La comptabilité salariale, tenue en cette occasion, compte d’ailleurs parmi les rares initiatives de gestion qui ont permis, durant au moins une décennie, de consigner les plus amples détails non seulement sur le profil distinctif de l’ensemble de ces intervenants, mais également sur leur origine géographique, voire confessionnelle.

  14. Two Concepts of Rationality

    Directory of Open Access Journals (Sweden)

    Danny Frederick

    2010-02-01

    Full Text Available The dominant tradition in Western philosophy sees rationality as dictating. Thus rationality may require that we believe the best explanation and simple conceptual truths and that we infer in accordance with evident rules of inference. I argue that, given what we know about the growth of knowledge, this authoritarian concept of rationality leads to absurdities and should be abandoned. I then outline a libertarian concept of rationality, derived from Popper, which eschews the dictates and which sees a rational agent as one who questions, criticises, conjectures and experiments. I argue that, while the libertarian approach escapes the absurdities of the authoritarian, it requires two significant developments and an important clarification to be made fully consistent with itself.

  16. Hybrid system concepts

    Landeyro, P.A.

    1995-01-01

    Hybrid systems studied for fissile material production, were reconsidered for minor actinide and long-lived fission product destruction as alternative to the traditional final disposal of nuclear waste. Now there are attempts to extend the use of the concepts developed for minor actinide incineration to plutonium burning. The most promising hybrid system concept considers fuel and target both as liquids. From the results obtained, the possibility to adopt composite targets seems the most promising solution, but still there remains the problem of Pu production, not acceptable in a burning system. This kind of targets can be mainly used for fissile material production, while for accelerator driven burners it is most convenient to use a liquid lead target. The most suitable solvent is heavy water for minor actinide annihilation in the blanket of a hybrid system. Due to the criticality conditions and the necessity of electric energy production, the blanket using plutonium dissolved in molten salts is the most convenient one. (author)

These different usages may be grouped together in three semantic fields (history as a way of knowing, as a way of being and as a way of doing, which correspond to three ways of understanding the Philosophy of History: as Epistemology of History, as Ontology of historicity and as ethical-political Critique of the present. On the other hand, I will show that these three concepts of history (and, accordingly, the three ways of understanding the Philosophy of History refer mutually to each other and, thus, are inseparable from each other.

    1985-01-01

    A newly introduced Japanese reactor concept, ISER (Intrinsically Safe and Economical Reactor), is intended to be a reference intrinsically safe light water reactor. ISER is designed similarly to PIUS but with greater economy in mind such that any utility in any country can choose it for its power system. Social assimilation and acceptability in the Asia Pacific Region including the United States are the keys to the ISER with the hope of dramatic reductions of social costs due to safeguards, reliability, financiability, and infrastructure building, particularly in the third world, as well as reactor safety itself. In this respect and others, the ISER proposal is different from other vendor-proposed reactor concepts and is unique

    This is an introduction to the major concepts in total quality management, a loose collection of management approaches that focus on continuous improvement of processes, guided by routine data collection and adjustment of the processes. Customer focus and involvement of all members of an organization are also characteristics commonly found in TQM. The seventy-five-year history of the movement is sketched from its beginning in statistical work on quality assurance through the many improvements and redefinitions added by American and Japanese thinkers. Essential concepts covered include: control cycles, focus on the process rather than the defects, the GEAR model, importance of the customer, upstream quality, just-in-time, kaizen, and service quality.

    Sood, D.D.

    1980-01-01

    Molten salt reactor is an advanced breeder concept which is suited for the utilization of thorium for nuclear power production. This reactor is based on the use of solutions of uranium or plutonium fluorides in LiF-BeF 2 -ThF 4 as fuel. Unlike the conventional reactors, no external coolant is used in the reactor core and the fuel salt itself is circulated through heat exchangers to transfer the fission produced heat to a secondary salt (NaF-NaBF 4 ) for steam generation. A part of the fuel stream is continuously processed to isolate 233 Pa, so that it can decay to fissile 233 U without getting converted to 234 Pa, and for the removal of neutron absorbing fission products. This on-line processing scheme makes this reactor concept to achieve a breeding ratio of 1.07 which is the highest for any thermal breeder reactor. Experimental studies at the Bhabha Atomic Research Centre, Bombay, have established the use of plutonium as fuel for this reactor. This molten salt reactor concept is described and the work conducted at the Bhabha Atomic Research Centre is summarised. (auth.)

  9. Four concepts of Africa

    Directory of Open Access Journals (Sweden)

    Willem Fourie

    2015-05-01

    Full Text Available What makes the words ‘Africa’ and ‘African’ possible and useful? In this article it is argued that at least four internally coherent concepts of Africa exist, and that none of these concepts are ethically neutral. The article is presented as a contribution to attempts at using the term ‘Africa’ in self-critical, reflexive and constructive ways. It could therefore be of interest to all researchers, particularly those in the humanities and theology, who locate their research within the context of ‘Africa’. It is argued that Africa can be conceived of as a place, a commodity, a condition and an ideal. By drawing on mostly primary sources it is shown that the term ‘Africa’ only relatively recently came to refer to a continent, that Africa as a place and Africa as a condition in need of betterment formed the foundation for its commodification, and that Africa only very recently became a self-description of the people who live on the continent of Africa. Each of these concepts of Africa is shown to be based on a particular logic with both strengths and weaknesses.

  10. SCWR Concept in Korea

    NONE

    2014-08-15

    One of the major difficulties in the design of an SCWR is the additional neutron moderation in order to compensate the low coolant density in the later stage of coolant heat-up. The water rod concept was introduced as a simple method to provide additional moderation, however it may result in an inevitable complexity in the design of the reactor upper part. A solid moderator concept was introduced in the Korean SCWR to avoid this difficulty. A conceptual design of a 1400 MWe SCWR core with a cruciform type of U/ZrH{sub 2} solid moderator has been studied. The design features include a solid moderator design, an axial zoning of the burnable poison and fuel rod, a flow rate control by adjusting the orifice design, and a control rod design for an excess reactivity control. The maximum power peaking is 2.48 and the maximum coolant temperature is 577°C. Reactivity coefficients such as the moderator temperature coefficient and fuel temperature coefficient are negative for the whole burn-up period. At a cold zero power condition, the minimum shutdown margin is 1.16%Δρ at the beginning of a cycle, which satisfies the required shutdown margin limit. The concept described here should not be considered as a complete one, but a preliminary idea. It is solely based on information frozen at the time, and is subject to further improvement.

Nous présentons dans ce papier, une nouvelle stratégie et de nouveaux concepts pour développer les SI pour l’e-Gouvernement. Cette stratégie est construite selon un cadre de référence comprenant quatre niveaux: le niveau ontologique, le niveau informationnel, le niveau des activités et le niveau d’implémentation informatique. Dans le cas des institutions, le niveau ontologique est construit à partir d’un ensemble de textes légaux. En effet, la particularité des métiers institutionnels est d’être régis par un cadre législatif qui constitue une source de connaissances précieuse et indiscutable. Un SI développé pour supporter les activités d’un domaine institutionnel doit se conformer à ce cadre législatif. Le but recherché est de construire un noyau informationnel fondé sur des concepts stables. Afin de rendre le SI opérationnel, un ensemble d’aspects organisationnels doit s’ajouter autour de ce noyau informationnel. Dans ce papier, nous nous intéressons principalement à l’étude des couches organisationnelles construites autour de ce noyau. Afin d’illustrer l’approche proposée, nous présentons un exemple d’un SI d’une université appliquant le traité des accords de Bologne.

    Cleary, M P; Vasselli, J R; Greenwood, M R

    1980-03-01

    The free-feeding, genetically obese rat is hyperphagic, hyperinsulinemic, and hypertriglyceridemic and has increased fat cell size and number compared to its lean littermate. These experiments demonstrate that, when fafa rats are prevented from expressing hyperphagia throughout life, the complete obese "syndrome" still develops. Furthermore, life-long food restriction does not prevent increased lipoprotein lipase in the fafa rat. The data support the concept that a peripheral metabolic adaptation, probably in lipid metabolism, results in preferential shunting of dietary substrate in the restricted obese rats to adipose tissue with concomitant decreases in other tissues.

    2013-01-01

    Over the past five years, pre-project formulation experts at the Jet Propulsion Laboratory (JPL) has developed and implemented a method for measuring and communicating the maturity of space mission concepts. Mission concept development teams use this method, and associated tools, prior to concepts entering their Formulation Phases (Phase A/B). The organizing structure is Concept Maturity Level (CML), which is a classification system for characterizing the various levels of a concept's maturity. The key strength of CMLs is the ability to evolve mission concepts guided by an incremental set of assessment needs. The CML definitions have been expanded into a matrix form to identify the breadth and depth of analysis needed for a concept to reach a specific level of maturity. This matrix enables improved assessment and communication by addressing the fundamental dimensions (e.g., science objectives, mission design, technical risk, project organization, cost, export compliance, etc.) associated with mission concept evolution. JPL's collaborative engineering, dedicated concept development, and proposal teams all use these and other CML-appropriate design tools to advance their mission concept designs. This paper focuses on mission concept's early Pre-Phase A represented by CMLs 1- 4. The scope was limited due to the fact that CMLs 5 and 6 are already well defined based on the requirements documented in specific Announcement of Opportunities (AO) and Concept Study Report (CSR) guidelines, respectively, for competitive missions; and by NASA's Procedural Requirements NPR 7120.5E document for Projects in their Formulation Phase.

Results: Nurses understand caring in nursing as a relationship with patients which is characterised on the nurses' part by an individual and empathetic approach, attentiveness, experience and sensitivity. Through caring, active communication takes place, providing information which reduces anxiety and leads to the breaking down of barriers. This relationship helps protect patients' autonomy, dignity and comfort. It requires experience on the part of nurses, and it is influenced by the environment. The nurses' personal qualities (what professional knowledge, attitudes and skills they have and their availability, reliability, and emotional and physical support are important to patients. Conclusion: The concept of caring is a content specific interpersonal process which is characterized by the professional knowledge, skills, personal maturity, and interpersonal sensitivity of nurses, which result in the protection, emotional support, and the meeting of bio-psycho-social needs of patients. The results of the overview study could contribute to an explanation and understanding of the nature of caring as a fundamental feature of the discipline of nursing.

  19. SCWR Concepts in Japan

    NONE

    2014-08-15

    Two SCWR concepts are being developed in Japan, one corresponding to the thermal spectrum reactor and the other to the fast spectrum reactor. Yamada et al. described the thermal-spectrum reactor concept referred to as the Japan SCWR (or JSCWR). This concept was developed under the financial support of the Ministry of Economy, Trade and Industry (METI). The basic philosophy of the JSCWR development is to utilize proven light water reactor and supercritical fossil-fired power plant technologies as much as possible to minimize the R&D cost, time and risks. Therefore, the JSCWR is designed as a thermal neutron spectrum reactor using light water as moderator and reactor coolant. The JSCWR plant consists of a pressure-vessel type, once-through reactor and a direct Rankine cycle system. Reactor coolant fed through inlet nozzles is heated up in the core and flows through outlet nozzles with no recirculation in the vessel. Other options to the JSCWR core design are being investigated at the University of Tokyo. The electric output of the JSCWR is assumed to range from 600 MWe to 1700 MWe class to fulfill user’s requirements as much as possible. In this section, the reference value is selected to 1725 MWe, which corresponds to a reactor thermal output of 4039 MWth. Nakatsuka et al. described the core design for the fast-spectrum reactor, which is based on a similar plant system compared to that of the thermal-spectrum reactor. The fast-spectrum reactor, however, would produce higher power rating than the thermal-spectrum one of the same reactor pressure-vessel size. Since the fast-spectrum reactor does not require the moderator, its unit capital cost would be lower than the thermal-spectrum reactor.

    LHD divertor development program has generated various innovative divertor concepts and technologies which will help to improve the plasma performance in both helical and tokamak devices. They are two divertor operational scenarios (confinement improvement by generating high temperature divertor plasma and simultaneous achievement of radiative cooling and H-mode-like confinement improvement). Local island divertor geometry has also been proposed. This new divertor has been successfully tested in the CHS device and is planned to be installed in the LHD device. In addition, technological development of new efficient hydrogen pumping schemes (carbon sheet pump and membrane pump) are being pursued for enhancement of the divertor control capability. 17 refs., 8 figs

    India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality.

    Mechatronic design implies the consideration of integrated mechanical, electrical, and local control characteristics in electromechanical device design. In this paper, mechatronic development of actuation device concepts for active aircraft aerodynamic flow control are presented and discussed. The devices are intended to be embedded in aircraft aerodynamic surfaces to provide zero-net-momentum jets or additional flow-vorticity to control boundary layers and flow- separation. Two synthetic jet device prototypes and one vorticity-on-demand prototype currently in development are described in the paper. The aspects of actuation materials, design approaches to generating jets and vorticity, and the integration of miniaturized electronics are stressed.

    1998-09-01

    Despite considerable expenditures for environmental protection and intensified efforts in the areas of environmental research and monitoring, environmental damage increasingly occurs, sometimes with global effects, largely due to the lack of early diagnosis. In the past few years various institutions have therefore demanded improvements in environmental monitoring. The Council of Experts on Environmental Issues (`Rat von Sachverstaendigen fuer Umweltfragen`, SRU), in particular, in its `Environmental Report` of 1987 and in its Special Report on `General Ecological Environmental Monitoring` (1990) presented far-reaching demands for a nationwide ecological early warning system which should integrate the various local, regional, national, and even global monitoring levels, and which should encompass an environmental monitoring of entire ecosystems at representative locations. This is aimed at creating the prerequisites for - detection of long-term gradual environmental change, - confirmation of refutation of initial assumptions regarding the causes of these environmental changes, - permitting decisions on preventive actions to stabilize or improve environmental conditions and - making it possible to assess the success of environmental protection policies. This report includes an abbreviated version and documentation of the conference on the `Concept for Integrated Environmental Monitoring` and the final report `Specification of the Concept for Integrated Environmental Monitoring from the Perspective of Nature Conservation`.

    1995-05-01

    The purpose of this work is to explore the feasibility of several advanced microwave processing concepts to develop new energy-efficient materials and processes. The project includes two tasks: (1) commercialization of the variable-frequency microwave furnace; and (2) microwave curing of polymer composites. The variable frequency microwave furnace, whose initial conception and design was funded by the AIC Materials Program, will allow us, for the first time, to conduct microwave processing studies over a wide frequency range. This novel design uses a high-power traveling wave tube (TWT) originally developed for electronic warfare. By using this microwave source, one can not only select individual microwave frequencies for particular experiments, but also achieve uniform power densities over a large area by the superposition of many different frequencies. Microwave curing of thermoset resins will be studied because it hold the potential of in-situ curing of continuous-fiber composites for strong, lightweight components. Microwave heating can shorten curing times, provided issues of scaleup, uniformity, and thermal management can be adequately addressed.

    Desjonquères, M -C

    1993-01-01

    This textbook is intended as an introduction to surface science for graduate students. It began as a course of lectures that we gave at the University of Paris (Orsay). Its main objectives are twofold: to provide the reader with a compre­ hensive presentation of the basic principles and concepts of surface physics and to show the usefulness of these concepts in the real world by referring to experiments. It starts at a rather elementary level since it only requires a knowledge of solid state physics, quantum mechanics, thermodynamics and statistical physics which does not exceed the background usually taught to students early in their university courses. However, since it finally reaches an advanced level, we have tried to render it as self-contained as possible so that it remains accessible even to an unexperienced reader. Furthermore, the emphasis has been put on a pedagogical level rather than on a technical level. In this spirit, whenever possible, models which are simplified, but which contain the featu...

  15. ATR performance modeling concepts

    2016-05-01

    Performance models are needed for automatic target recognition (ATR) development and use. ATRs consume sensor data and produce decisions about the scene observed. ATR performance models (APMs) on the other hand consume operating conditions (OCs) and produce probabilities about what the ATR will produce. APMs are needed for many modeling roles of many kinds of ATRs (each with different sensing modality and exploitation functionality combinations); moreover, there are different approaches to constructing the APMs. Therefore, although many APMs have been developed, there is rarely one that fits a particular need. Clarified APM concepts may allow us to recognize new uses of existing APMs and identify new APM technologies and components that better support coverage of the needed APMs. The concepts begin with thinking of ATRs as mapping OCs of the real scene (including the sensor data) to reports. An APM is then a mapping from explicit quantized OCs (represented with less resolution than the real OCs) and latent OC distributions to report distributions. The roles of APMs can be distinguished by the explicit OCs they consume. APMs used in simulations consume the true state that the ATR is attempting to report. APMs used online with the exploitation consume the sensor signal and derivatives, such as match scores. APMs used in sensor management consume neither of those, but estimate performance from other OCs. This paper will summarize the major building blocks for APMs, including knowledge sources, OC models, look-up tables, analytical and learned mappings, and tools for signal synthesis and exploitation.

    2007-01-01

    In Madagascar, the sealed radioactive sources are used in several socioeconomic sectors such as medicine, industry, research and agriculture. At the end of their useful lives, these radioactive sources become radioactive waste and can be still dangerous because they can cause harmful effects to the public and the environment. This work entitled 'Borehole disposal design concept' consists in putting in place a site of sure storage of the radioactive waste, in particular, sealed radioactive sources. Several technical aspects must be respected to carry out such a site like the geological, geomorphologic, hydrogeologic, geochemical, meteorological and demographic conditions. This type of storage is favorable for the developing countries because it is technologically simple and economic. The cost of construction depends on the volume of waste to store and the depth of the Borehole. The Borehole disposal concept provides a good level of safety to avoid the human intrusion. The future protection of the generations against the propagation of the radiations ionizing is then assured. [fr

    2014-01-01

    A lighter, more robust airframe is one of the key technological advancements necessary for the successful launch of any large next-generation transport aircraft. Such a premise dictates that considerable improvements beyond current state-of-the-art aluminum structures is needed, and that improvements of this magnitude will require an extensive use of composite materials that are not only lightweight, but also economical to produce. To address this challenge, researchers at NASA and The Boeing Company are developing a novel structural concept called the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) under the Environmentally Responsible Aviation (ERA) Project. It is an integrally stiffened panel concept that is stitched together and designed to maintain residual load-carrying capabilities under a variety of damage scenarios. In addition to improved structural performance, an important facet of this unique arrangement of stitched carbon fibers is its innovative manufacturing method that has the potential to lower fabrication costs by eliminating fasteners and autoclave cures. The rationale and development status for this new approach forms the basis of the work described in this paper. The test specimens described herein were fabricated, or are currently being fabricated, by The Boeing Company, while the structural analyses and testing tasks are being performed by NASA and Boeing personnel.

    2010-01-01

    Full Text Available The active publics issue and the question of the construction of publics are relatively recent in communication studies. After an initial period, when mass communication was seen as aiming at a holistic public, massified and passive and, thus, supposedly influenced via "targeted" messages, now the views on what "publics" mean is becoming diversified and nuanced under the influence of literary theories, cultural studies and what was later called "reception studies". Thus, from the "mass public" we got to the concept of "publics". However, in some recent studies, the mere existence of these publics is being questioned.In this paper, we detail the history of theories on the "public" - from the perspective of the public-as-spectator which later became public-as-audience and public-as-actor - and we set ourselves to show how, from theories on the re-active publics, we arrived, through the transformation of television and the emergence of the new IT&C, to the concept of publics as pro-active as a result of media efforts to build this activism.

  19. Concept of 'bad death'

    Directory of Open Access Journals (Sweden)

    Marija Vučković

    2016-02-01

    Full Text Available Following previous research on the linguistic concept of а 'bad death' which lexical expression is the word family of the verb ginuti, I focus my attention in this paper on the relationship between language conceptualization of а 'bad death' and the representation of а 'bad death' in traditional and contemporary culture. Diachronically based language corpus makes possible to trace the changes of referential frame and use of verb ginuti and its derivatives. In the traditional culture а 'bad death' is marked in action code by irregular way of burial and beliefs in demons stemming from the 'impure dead'. In the paper I explore the degree of synonymy of the symbols of all three codes: verbal code, action code and code of beliefs. In the contemporary culture the lack of individual control and choice is considered to be the key element of the concept of a 'bad death'. This change of conceptual content manifests itself in the use of its lexical expressions.

  20. Sellafield repository design concept

    International Nuclear Information System (INIS)

    1998-01-01

    Between 1989 and 1997, UK Nirex Ltd carried out a programme of investigations to evaluate the potential of a site adjacent to the BNFL Sellafield works to host a deep repository for the United Kingdom's intermediate-level and certain low-level radioactive waste. The programme of investigations was wound down following the decision in March 1997 to uphold the rejection of the Company's planning application for the Rock Characterisation Facility (RCF), an underground laboratory which would have allowed further investigations to confirm whether or not the site would be suitable. Since that time, the Company's efforts in relation to the Sellafield site have been directed towards documenting and publishing the work carried out. The design concept for a repository at Sellafield was developed in parallel with the site investigations through an iterative process as knowledge of the site and understanding of the repository system performance increased. This report documents the Sellafield repository design concept as it had been developed, from initial design considerations in 1991 up to the point when the RCF planning application was rejected. It shows, from the context of a project at that particular site, how much information and experience has been gained that will be applicable to the development of a deep waste repository at other potential sites

  1. The EXTRAP concept

    International Nuclear Information System (INIS)

    Lehnert, D.

    1976-11-01

    A review is given of a recently suggested axially symmetric, quasi-steady, closed, high-beta confinement system. A toroidal pinch of non-circular cross section is supposed to be immersed in the strong, inhomogenous poloidal vacuum field from a set of ring-shaped conductors, all carrying currents in the opposite direction of the plasma current. Preliminary experiments are reported. This 'EXTRAP' concept is expected to have some important advantages, as compared to magnetic bottles based on a main toroidal field component. Concerning plasma equilibrium, there are closed local and average guiding center orbits, beta values of order unity should become available, there is no magnetic surface splitting limit, cyclotron radiation should be kept at an acceptably low level, and bootstrap operation may become possible. Concerning plasma stability, the system should not become sensitive to magnetic island formation and asymmetries, and the short magnetic connection lengths as well as the strong vacuum field gradients should favour stabilization of flute-type, kink, and other magnetohydrodynamic modes. Concerning reactor technology, high power densities are expected to be reached, superconducting coils should not become necessary, the coil stresses are moderate, and repair and replacement are facilitated by the coil geometry. Before a final judgement can be made on this concept, however, extensive experiments and further theoretical analysis are ndeeded. (Auth.)

  2. Copies, Concepts and Time

    Directory of Open Access Journals (Sweden)

    Anne Eriksen

    2017-09-01

    Full Text Available Copies are defined by their relation to an original. The understanding and evaluation of this relationship has been changing over time. A main argument of this article is that originals and copies are phenomena with no "natural" or essential meaning outside of their specific historical settings. The idea to be explored is how changing historicity regimes have transformed notions of originals and copies over time and how these differences also are reflected in the intrinsically temporal relation between the two concepts. The discussion will be framed by two theory sets. The first is Alexander Nagel and Christopher Woods investigation of two kinds of temporality that vied for dominance in works of art in the late Middle Ages and the Renaissance. The second is Walter Benjamins discussion of artwork in the "age of mechanical reproduction", i.e. the twentieth century. The second half of the article seeks to add to the historical complexity described by both theory sets by introducing a concept of tradition and discussing the early modern ideals of exemplarity, emulation and copiousness.

  3. Concepts of magnetospheric convection

    International Nuclear Information System (INIS)

    Vasyliunas, V.M.

    1975-01-01

    Magnetospheric physics, which grew out of attempts to understand the space environment of the Earth, is becoming increasingly applicable to other systems in the Universe. Among the planets, in addition to the Earth, Jupiter, Mercury, Mars and (in a somewhat different way) Venus are now known to have magnetospheres. The magnetospheres of pulsars have been regarded as an essential part of the pulsar phenomenon. Other astrophysical systems, such as supernova remnant shells or magnetic stars and binary star systems, may be describable as magnetospheres. The major concepts of magnetospheric physics thus need to be formulated in a general way not restricted to the geophysical context in which they may have originated. Magnetospheric convection has been one of the most important and fruitful concepts in the study of the Earth's magnetosphere. This paper describes the basic theoretical notions of convection in a manner applicable to magnetospheres generally and discusses the relative importance of convective corotational motions, with particular reference to the comparison of the Earth and Jupiter.

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

    2011-02-15

    Safe storage of radioactive waste is a major challenge for the nuclear industry. Mineralogy is a good basis for designing ceramics, which could eventually replace nuclear glasses. This requires a new storage concept: separation-conditioning. Basic rules of crystal chemistry allow one to select the most suitable structures and natural occurrences allow assessing the long-term performance of ceramics in a geological environment. Three criteria are of special interest: compatibility with geological environment, resistance to natural fluids, and effects of self-irradiation. If mineralogical information is efficient for predicting the behaviour of common, well-known minerals, such as zircon, monazite or apatite, more research is needed to rationalize the long-term behaviour of uncommon waste form analogs.

    Lhomme, J. P.; Monteny, B.

    1982-03-01

    This paper begins to recall new concepts concerning evapotranspiration as they have been specified by the round-table conference of Budapest in May 1977. The potential evaporation ( EP) is now defined as the evaporation of a crop whose all exchange surfaces (leaves, stalks,...) are saturated, i.e., covered with a thin film of water. It can be calculated by a theoretical formula of Penman type. We give the reasons why it is interesting to use grass potential evaporation ( EP g ) as reference. The empirical relationships to estimate in this case the net radiation and the aerodynamic component of the formula have been derived from measurements made in Ivory Coast (West Africa). The relationship (8) has been obtained. It gives the daily value of EP g in millimeters of water per day (mm/d). The values calculated by this formula are compared to measurements of grass maximal evapotranspiration ( ETM g ).

  13. COMPETING CONCEPTIONS OF GLOBALIZATION

    Directory of Open Access Journals (Sweden)

    Leslie Sklair

    2015-08-01

    Full Text Available Globalization is a relatively new idea in the social sciences, although people who work in and write about the mass media, transnational corporations and international business have been using it for some time. The purpose of this paper is to critically review the ways in which sociologists and other social scientists use ideas of globalization and to evaluate the fruitfulness of these competing conceptions. The central feature of the idea of globalization is that many contemporary problems cannot be adequately studied at the level of nation-states, that is, in terms of each country and its inter-national relations. Instead, they need to be conceptualized in terms of global processes. Some have even gone so far as to predict that global forces, by which they usually mean transnational corporations and other global economic institutions, global culture or globalizing belief systems/ideologies of various types, or a combination of all of these, are becoming so powerful that the continuing existence of the nation-state is in serious doubt. This is not a necessary consequence of most theories of globalization. The argument of this paper is that much of the globalization literature is confused because not all those who use the term distinguish it clearly enough from internation-alization, and some writers appear to use the two terms interchangeably. I argue that a clear distinction must be drawn between the inter-national and the global. The hyphen in inter-national is to distinguish (inadequate conceptions of the global' founded on the existing even if changing system of nation-states, from (genuine conceptions of the global based on the emergence of global processes and a global system of social relations not founded on national characteristics or nation-states. This global system theory is the framework for my own research. Globalization studies can be categorized on the basis of four research clusters:1. The world-systems approach; 2. The global

    2017-07-12

    'H2@Scale' is an opportunity for wide-scale use of hydrogen as an intermediate that carries energy from various production options to multiple uses. It is based on identifying and developing opportunities for low-cost hydrogen production and investigating opportunities for using that hydrogen across the electricity, industrial, and transportation sectors. One of the key production opportunities is use of low-cost electricity that may be generated under high penetrations of variable renewable generators such as wind and solar photovoltaics. The technical potential demand for hydrogen across the sectors is 60 million metric tons per year. The U.S. has sufficient domestic renewable resources so that each could meet that demand and could readily meet the demand using a portfolio of generation options. This presentation provides an overview of the concept and the technical potential demand and resources. It also motivates analysis and research on H2@Scale.

    Football is one of the most popular sports in the United States and is the leading cause of sports-related injury. A large focus in recent years has been on concussions, sudden cardiac death, and heat illness, all thought to be largely preventable health issues in the young athlete. Injury prevention through better understanding of injury mechanisms, education, proper equipment, and practice techniques and preseason screening may aid in reducing the number of injuries. Proper management of on-field injuries and health emergencies can reduce the morbidity associated with these injuries and may lead to faster return to play and reduced risk of future injury. This article reviews current concepts surrounding frequently seen football-related injuries.

    Full Text Available Ibn Sina (Latin name – Avicenna, 980–1037 is a famous Muslim physician who wrote The Canon of Medicine. Pain-related writings within The Canon were identified and analysed and compared to Galen and Modern Pain Theory. We found evidence in The Canon that Avicenna challenged Galen's concept of pain. Galen insisted that injuries (breach of continuity were the only cause of pain. In contrast, Avicenna suggested that the true cause of pain was a change of the physical condition (temperament change of the organ whether there was an injury present or not. Avicenna extended Galen's descriptions of 4 to 15 types of pain and used a terminology that is remarkably similar to that used in the McGill Pain Questionnaire.

    Full Text Available A point-mass concept has been elaborated from the equations of the gravitational field. One application of these deductions results in a black hole configuration of the Schwarzschild type, having no electric charge and no angular momentum. The critical mass of a gravitational collapse with respect to the nuclear binding energy is found to be in the range of 0.4 to 90 solar masses. A second application is connected with the spec- ulation about an extended symmetric law of gravitation, based on the options of positive and negative mass for a particle at given positive energy. This would make masses of equal polarity attract each other, while masses of opposite polarity repel each other. Matter and antimatter are further proposed to be associated with the states of positive and negative mass. Under fully symmetric conditions this could provide a mechanism for the separation of antimatter from matter at an early stage of the universe.

  3. Students' conceptions about force

    2005-01-01

    Students from a young age have developed in their own minds differing concepts of things such as all creatures having a soul. Also children see the environment and interpret what they see according to their own understanding and explanation. In particular, with regards to physics, things like light, heat, motion, structure of matter and energy are understood at the level of a child s comprehension. Most often the child s understanding varies quite differently from the actual true meaning. As a result the child is reluctant to accept any other explanation. In such situations the necessary difficulties must be tackled with care and caution pertinent to the individual. Studies at K.S.U University related to force and motion of various departments in the Faculty of Science and Letters have been investigated. After evaluations of all the findings a number of suggestions have been made to change student views and ideas

  4. Advocacy: exploring the concept.

    Mardell, A

    1996-10-01

    The concept of the nurse as the patient's advocate is one that has become popular in the last fifteen years or so in both North America and the United Kingdom, having its basis in nursing theory. The UKCC first embraced the concept, stating in the Code of Professional Conduct that nurses must; 'act always in such a manner so as to promote and safeguard the interests and well being of patients and clients'. This is a laudable principle and one that nurses cannot dispute as there are many members of our society who are weak and vulnerable and may be unable to speak up for themselves. But are nurses always in a position to be an advocate for their patients? As the nature of nursing is so diverse then the nature of advocacy will be different in the multifarious settings in which nurses practise. Can theatre nurses ever be in a position to act as an advocate for a patient who is often anaesthetised? What precisely is advocacy and is the Concise Oxford Dictionary definition of 'one who pleads for another' appropriate in the nursing context? Then there is the position of nurses in the healthcare organisation in which they practise. In advocating for their patients, nurses may find they are pleading a case for a patient, or a group of patients, that could bring the nurse into conflict with their medical colleagues or with the management of the organisation by whom they are employed. Additionally, they may not posses the skills and knowledge to advocate effectively under such circumstances. Nursing is littered with the casualties of such conflicts over the years, the most publicised of whom, in the UK, was probably Graham Pink who lost his job as a charge nurse after drawing public attention to what he considered to be an unacceptable standard of care in the hospital in which he worked.

    The rat genome database RatMap (http://ratmap.org or http://ratmap.gen.gu.se) has been one of the main resources for rat genome information since 1994. The database is maintained by CMB–Genetics at Göteborg University in Sweden and provides information on rat genes, polymorphic rat DNA-markers and rat quantitative trait loci (QTLs), all curated at RatMap. The database is under the supervision of the Rat Gene and Nomenclature Committee (RGNC); thus much attention is paid to rat gene nomenclature. RatMap presents information on rat idiograms, karyotypes and provides a unified presentation of the rat genome sequence and integrated rat linkage maps. A set of tools is also available to facilitate the identification and characterization of rat QTLs, as well as the estimation of exon/intron number and sizes in individual rat genes. Furthermore, comparative gene maps of rat in regard to mouse and human are provided. PMID:15608244

    Full Text Available À la fin de l’Ancien Régime, les villes des Pays-Bas gardaient les traits de villes médiévales sans ordre et faites d’entrelacs de rues et de ruelles. Le caractère corporatif de la production limitait la présence de grands ensembles industriels et les couvents et leurs jardins occupaient une grande partie de la superficie intra et extra muros des cités. Par ailleurs, l’Église était propriétaire d’un important parc immobilier de petites demeures adossées à des églises jusqu’aux importants refuges d’abbayes dominant dans les campagnes de vastes espaces fonciers. Durant la deuxième moitié du xviiie, les autorités habsbourgeoises menèrent une politique tendant à moderniser les villes en faisant, en autres, tomber les enceintes et en donnant une nouvelle affectation aux couvents contemplatifs supprimés. La Révolution française bouleversa ces ensembles urbains en libérant d’un coup une masse très importante de biens immobiliers qui appartenait à l’Église et en modifiant radicalement les modes de production par la suppression des corporations de métiers. La bourgeoisie principalement négociante réussi habilement tirer tous les profits de cette nouvelle donne. Cet effet d’aubaine contribua grandement à faire passer nos régions dans un nouveau stade de leur démarrage industriel.At the end of the Ancien Régime, the towns of the Netherlands retained the characteristics of medieval towns, without any order and consisting of warrens of streets and alleys.

    To report an analysis of the concept of befriending. Befriending is an intervention used in a range of nursing, health and social care settings to provide support for individuals who are socially isolated or lack social support. However, in many cases befriending and its impact remains poorly understood and under researched. Concept analysis provides clarification of the concept and basis for further research and development. Concept analysis. AMED, Psyc Articles, Psych Info, Medline, MedlinePlus, Social Science Index and CINHAL databases were searched for literature published between 1993-2013 using the search term Befriending. Walker and Avant's method of concept analysis was chosen. This combined with insights from Risjord's work produced a theoretical concept analysis which focused on the concept in peer reviewed academic literature. There are currently several ways the mechanisms of befriending and its effects on individuals and communities are understood. It is possible however to identify key attributes which define the concept and differentiate it from related concepts, such as peer support and mentoring. Key attributes are that it is an organised intervention, involving the creation of an emotionally connected friend-like relationship, where there is a negotiation of power. This concept analysis has clarified current understandings and uses of befriending. It provides the basis for widening the focus of research into the effectiveness and impact of befriending on those who are befriended, those who befriend and the communities where befriending takes place. © 2014 John Wiley & Sons Ltd.

  10. Alien Sunset (Artist Concept)

    2007-01-01

    Our solitary sunsets here on Earth might not be all that common in the grand scheme of things. New observations from NASA's Spitzer Space Telescope have revealed that mature planetary systems -- dusty disks of asteroids, comets and possibly planets -- are more frequent around close-knit twin, or binary, stars than single stars like our sun. That means sunsets like the one portrayed in this artist's photo concept, and more famously in the movie 'Star Wars,' might be quite commonplace in the universe. Binary and multiple-star systems are about twice as abundant as single-star systems in our galaxy, and, in theory, other galaxies. In a typical binary system, two stars of roughly similar masses twirl around each other like pair-figure skaters. In some systems, the two stars are very far apart and barely interact with each other. In other cases, the stellar twins are intricately linked, whipping around each other quickly due to the force of gravity. Astronomers have discovered dozens of planets that orbit around a single member of a very wide stellar duo. Sunsets from these worlds would look like our own, and the second sun would just look like a bright star in the night sky. But do planets exist in the tighter systems, where two suns would dip below a planet's horizon one by one? Unveiling planets in these systems is tricky, so astronomers used Spitzer to look for disks of swirling planetary debris instead. These disks are made of asteroids, comets and possibly planets. The rocky material in them bangs together and kicks up dust that Spitzer's infrared eyes can see. Our own solar system is swaddled in a similar type of disk. Surprisingly, Spitzer found more debris disks around the tightest binaries it studied (about 20 stars) than in a comparable sample of single stars. About 60 percent of the tight binaries had disks, while the single stars only had about 20 percent. These snug binary systems are as close or closer than just three times the distance between Earth and

    Linguistic and non-linguistic pattern learning have been studied separately, but we argue for a comparative approach. Analogous inductive problems arise in phonological and visual pattern learning. Evidence from three experiments shows that human learners can solve them in analogous ways, and that human performance in both cases can be captured by the same models. We test GMECCS (Gradual Maximum Entropy with a Conjunctive Constraint Schema), an implementation of the Configural Cue Model (Gluck & Bower, ) in a Maximum Entropy phonotactic-learning framework (Goldwater & Johnson, ; Hayes & Wilson, ) with a single free parameter, against the alternative hypothesis that learners seek featurally simple algebraic rules ("rule-seeking"). We study the full typology of patterns introduced by Shepard, Hovland, and Jenkins () ("SHJ"), instantiated as both phonotactic patterns and visual analogs, using unsupervised training. Unlike SHJ, Experiments 1 and 2 found that both phonotactic and visual patterns that depended on fewer features could be more difficult than those that depended on more features, as predicted by GMECCS but not by rule-seeking. GMECCS also correctly predicted performance differences between stimulus subclasses within each pattern. A third experiment tried supervised training (which can facilitate rule-seeking in visual learning) to elicit simple rule-seeking phonotactic learning, but cue-based behavior persisted. We conclude that similar cue-based cognitive processes are available for phonological and visual concept learning, and hence that studying either kind of learning can lead to significant insights about the other.

    A proposed means of transmuting key long-lived radioactive isotopes, primarily the so-called minor actinides (Np, Am, Cm), using a hybrid proton-accelerator-sub-critical lattice, is described. It is argued that by partitioning the components of the light water reactor (LWR) spent fuel and by transmuting key elements, such as the plutonium, the minor actinides, and a few of the long-lived fission products, that some of the most significant challenges in building a waste repository can be substantially reduced. If spent fuel partitioning and transmutation were fully implemented, the time required to reduce the waste stream toxicity below that of uranium ore would be reduced from more than 10,000 years to approximately 30 years. The proposed machine, based on the described PHOENIX Concept, would transmute the minor actinides and much of the iodine produced by 75 LWRs, and would generate usable electricity (beyond that required to run the large accelerator) of 850 MW e . 14 refs., 29 figs

    Contaminated soils and buried wastes represent one of the most widespread and costly remediation problems in the United States and other developed countries around the world. This concept of in situ remediation using a plasma arc torch should be directly applicable to many of the contaminated soil remediation needs described the DOE, EPA, and DoD. Plasma Remediation of In Situ Materials (PRISM) could provide a highly efficient, cost-effective, reliable and controllable technique to selectively melt and vitrify any contaminated/buried volume of soils, materials, or objects at any depth underground. If necessary, it could pinpoint underground objects such as buried drums for selective remediation. Plasma arc technology was developed over 30 years ago by NASA for the US space program to simulate reentry temperatures on heat shields. Only recently has this technology begun to emerge as a commercial tool in several industries such as steelmaking, metallurgy, precious metal recovery, and waste disposal. Conceptually, a plasma torch could be used on the ground surface or lowered to the bottom of a small diameter, cased borehole. By raising and operating the torch at progressively higher levels a column of contaminated material would be vitrified and converted into an environmentally safe, glassy residue, highly resistant to leaching. With proper borehole spacing the vitrified columns could be coalesced together to form a contiguous, homogeneous mass of vitrified material which is environmentally safe and highly resistant to leaching

    1976-01-01

    The Tokamak Fusion Test Reactor, to be located on the Princeton Forrestal Campus, is expected to operate with 1 to 2.5 MA tritium--deuterium plasmas, with the pulses involving injection of 50 to 150 Ci (5 to 16 mg) of tritium. Attainment of fusion conditions is based on generation of an approximately 1 keV tritium plasma by ohmic heating and conversion to a moderately hot tritium--deuterium ion plasma by injection of a ''preheating'' deuterium neutral beam (40 to 80 keV), followed by injection of a ''reacting'' beam of high energy neutral deuterium (120 to 150 keV). Additionally, compressions accompany the beam injections. Environmental, safety and cost considerations led to the decision to limit the amount of tritium gas on-site to that required for an experiment, maintaining all other tritium in ''solidified'' form. The form of the tritium supply is as uranium tritide, while the spent tritium and other hydrogen isotopes are getter-trapped by zirconium--aluminum alloy. The issues treated include: (1) design concepts for the tritium generator and its purification, dispensing, replenishment, containment, and containment--cleanup systems; (2) features of the spent plasma trapping system, particularly the regenerable absorption cartridges, their integration into the vacuum system, and the handling of non-getterables; (3) tritium permeation through the equipment and the anticipated releases to the environment; (4) overview of the tritium related ventilation systems; and (5) design bases for the facility's tritium clean-up systems

    2017-01-01

    The purpose of this article is to conceptually examine intuition; identify the importance of intuition in nursing education, clinical practice, and patient care; encourage acceptance of the use of intuition; and add to the body of nursing knowledge. Nurses often report using intuition when making clinical decisions. Intuition is a rapid, unconscious process based in global knowledge that views the patient holistically while synthesizing information to improve patient outcomes. However, with the advent of evidence-based practice (EBP), the use of intuition has become undervalued in nursing. Walker and Avant's framework was used to analyze intuition. A literature search from 1987 to 2014 was conducted using the following keywords: intuition, intuition and nursing, clinical decision making, clinical decision making and intuition, patient outcomes, EBP, and analytical thinking. The use of intuition is reported by nurses, but is not legitimized within the nursing profession. Defining attributes of intuition are an unconscious, holistic knowledge gathered without using an analytical process and knowledge derived through synthesis, not analysis. Consequences include verification of intuition through an analytical process and translating that knowledge into a course of action. This article supports the use of intuition in nursing by offering clarity to the concept, adds to the nursing knowledge base, encourages a holistic view of the patient during clinical decision making, and encourages nurse educators to promote the use of intuition. © 2016 Wiley Periodicals, Inc.

    For the characterization of components, systems and signals in the radiofrequency (RF) and microwave ranges, several dedicated instruments are in use. In this article the fundamentals of the RF signal techniques are discussed. The key element in these front ends is the Schottky diode which can be used either as a RF mixer or as a single sampler. The spectrum analyser has become an absolutely indispensable tool for RF signal analysis. Here the front end is the RF mixer as the RF section of modern spectrum analyses has a ra ther complex architecture. The reasons for this complexity and certain working principles as well as limitations are discussed. In addition, an overview of the development of scalar and vector signal analysers is given. For the determination of the noise temperature of a one-port and the noise figure of a two-port, basic concepts and relations are shown as well as a brief discussion of commonly used noise-measurement techniques. In a further part of this article the operating principles of n...

    The article outlines the progress to date on AECL spent-nuclear fuel geological disposal concept. Hearings for discussion, organised by the federal Environmental Assessment Review Panel, of issues related to this type of disposal method occur in three phases, phase I focuses on broad societal issues related to long term management of nuclear fuel waste; phase II will focus on the technical aspects of this method of disposal; and phase III will consist of community visits in New Brunswick, Quebec, Ontario, Manitoba and Saskatchewan. This article provides the events surrounding the first two weeks of phase I hearings (extracted from UNECAN NEWS). In the first week of hearings, where submissions on general societal issues was the focus, there were 50 presentations including those by Natural Resources Canada, Energy Probe, Ontario Hydro, AECL, Canadian Nuclear Society, Aboriginal groups, environmental activist organizations (Northwatch, Saskatchewan Environmental Society, the Inter-Church Uranium Committee, and the Canadian Coalition for Nuclear responsibility). In the second week of hearings there was 33 presentations in which issues related to siting and implementation of a disposal facility was the focus.

    An increase in the efficiency of NPPs with light-water reactors through ‘nuclear’ steam superheating was one of the problems solved in the field of nuclear power industry. The commissioning of the Beloyarsk NPP, Units 1&2 with the channel-type reactor in the sixties of the 20th century showed the potential of realization of this idea and the necessity to solve a series of problems in technology and materials science. The NPP operation experience, elaboration and operational experience of steam superheating channels are extremely important in choosing the ways of design development of Generation IV reactors with supercritical pressure coolant water. The first technical proposal on a supercritical water cooled reactor of vessel type made in Russia in 1986 was the design of a two-circuit reactor plant (RP). The concept of the two-circuit RP of integrated type VVER-SCP-I with electric power of 500 MW was proposed in 1990. The design activities on these projects were performed at OKB GIDROPRESS and the analyses were carried out at the RRC Kurchatov Institute. The State Science Center of the Russian Federation Institute of Physics and Power Engineering (SSC RF IPPE) has been performing the computational studies of a single-circuit RP VVER-SCP since 2001. In 2006 OKB GIDROPRESS launched the design effort and computational analyses to corroborate the design of a single loop RP.

    Full Text Available Les États-Unis font rarement appel à un discours basé sur la défense de leurs propres intérêts nationaux pour défendre sa politique étrangère. Dans leur discours officiel, ils tentent plutôt de subordonner l’intérêt national aux objectifs plus nobles de défendre les droits de l’homme ou la démocratie.

Puis, il tente d’analyser le rôle important joué par ce discours, suggérant qu’il est révélateur d’une nouvelle forme d’impérialisme. Elle est nouvelle dans la mesure où l’État-nation dominant se présente comme l’incarnation de la démocratie libérale faisant en sorte que ses propres intérêts coïncident avec ceux de la démocratie libérale. Le discours idéaliste serait, selon l’auteur, non pas une façade, mais plutôt un élément essentiel d’une nouvelle forme d’impérialisme car la relation étroite qui s’établit entre démocratie libérale et interventionnisme américain renforcerait les intérêts du capitalisme moderne.

    Dans un contexte constructiviste, les connaissances anterieures d'un individu sont essentielles a la construction de nouvelles connaissances. Quelle qu'en soit la source (certaines de ces connaissances ont ete elaborees en classe, d'autres ont ete elaborees par interaction personnelle de l'individu avec son environnement physique et social), ces connaissances, une fois acquises, constituent les matieres premieres de l'elaboration des nouvelles conceptions de cet individu. Generalement, cette influence est consideree comme positive. Cependant, dans un milieu scolaire ou l'apprentissage de certaines conceptions enchassees dans un programme d'etudes et enterinees par l'ensemble d'une communaute est obligatoire, certaines connaissances anterieures peuvent entraver la construction des conceptions exigees par la communaute. La litterature abonde de tels exemples. Cependant, certaines connaissances anterieures, en soi tout a fait conformes a l'Heritage, peuvent aussi, parce qu'utilisees de facon non pertinente, entraver la construction d'une conception exigee par la communaute. Ici, la litterature nous donne peu d'exemples de ce type, mais nous en fournirons quelques-uns dans le cadre theorique, et ce sera un d'entre eux qui servira de base a nos propos.

    Following a historical approach, the authors first describe the original development of the concept of inhibition in neurophysiology and then analyze the subsequent adaptations made in psychiatry around such concept including those of: -- Pavlov, Hull, Watson and the behaviorists, -- Freud and the Freudian School, -- clinicians and psychopharmacologists. The concept of inhibition has thus various meanings in psychiatry. Although some unity is achieved on the semiological level, this aspect cannot explain the extent of the process.

    Mental health is an important measure of public health (WHO, 2004); however, nursing practice and research continues to prioritize mental illness, rather than well-being (Wand, 2011). Flourishing is a recent concept in the field of well-being. The term has been used sparingly in nursing practice and research, and conceptual clarification is needed to promote comprehensive understanding of the phenomenon. The purpose of this study is to critically analyze flourishing, assess the maturity of the concept, and provide recommendations for future research, education, and practice. The concept of flourishing was analyzed using the evolutionary approach to concept analysis (Rodgers, 2000). A search for articles on flourishing within the context of well-being was conducted through CINAHL, MEDLINE, and PsycINFO. A sample of 32 articles and 1 book was reviewed. Data were reviewed for concept attributes, antecedents, consequences, surrogate terms and related concepts. Four models of flourishing were identified with six overlapping attributes: meaning, positive relationships, engagement, competence, positive emotion, and self-esteem. Limited longitudinal and predictive studies have been conducted, but there is evidence for several antecedents and outcomes of flourishing. Research is ongoing primarily in psychology and sociology and is lacking in other disciplines. The concept of flourishing is immature; however, evidence is building for related concepts. A lack of consistent terminology regarding flourishing prevents knowledge development of flourishing as a distinct concept. Further multidisciplinary research is needed to establish standard operational and conceptual definitions and develop effective interventions.

    Full Text Available In our time Church Slavonic is a “language without native speakers,” but it is not in all respects a “dead” one. It is for this reason that the Slavs have given it a great variety of names, the different use of which in philological publications heavily depends on the respective linguists’ connotative purposes (e.g., national and ideological interests and so forth. As a rule, the description of the language is based on the analysis of written or printed texts. Only recently have a few additional corpora been introduced in addition to the well-known group of “classical” Old Church Slavonic manuscripts, which, for all their merits in the history of Slavistics, can give only a vague idea of the rich language tradition of Church Slavonic as a whole, since, as a means of actual (oral communication, it can nowadays be observed only in the liturgy. The article discusses the main linguistic conceptions applied to Church Slavonic in the past and present (root language, i.e., proto-language, common language, literary language [Schriftsprache], Ausbau language, etc.; singles out binaristic approaches in opposition to vernaculars; gives an overview of the numerous varieties to be differentiated within the language (connected to regions, chronology, functions, individuals, and groups; recalls the role of reconstruction in modern textbooks and the widely neglected construction devices used in early grammars and dictionaries; and, at the end, refers to the possibility of including Church Slavonic as a model for comparative judgments on degrees of diversity in the structural development of Slavonic languages.

  7. Concepts in radiation protection

    International Nuclear Information System (INIS)

    Oncescu, M.

    1996-01-01

    This monograph provides basic notions and principles in dosimetry and radiation protection in compliance with two fundamental works: IAEA Safety Series No.115 - International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources - and Publication no. 60 of International Commission on Radiological Protection. After the review of quantities and units necessary in radiation protection, the book presents the new values of dose limits as well as the values of 'radiation weighting factor', 'tissue weighting factor' and 'conversion factor intake-dose' (committed effective dose per unit intake) by ingestion and inhalation for 30 most important radionuclides. The new values of dose limits, lower than the old values, are a challenge for the radiation protection, especially of the 'public' where the dose limit diminished by a factor of five relative to the earlier edition. The new value of dose limit for public, 1 mSv per year (obviously over the natural exposure of 2.4 mSv per year), imposes new action ways and levels in radiation protection, especially in some cases of exacerbated natural radioactivity. The book provides the calculus of external exposure with the Gamma constant expressed in adequate units, to make the calculation easier. In the calculus of protection shield for gamma sources one uses a method, which while approximate helps save time. The calculus of internal exposure is made using the conversion factor intake-dose. Finally, the 'dosimetric watch' of the natural and artificial radioactivity of the atmosphere, hydrosphere and biosphere is intended to comply with the International Basic Safety Standards. Each chapter ends with a set of illustrative problems which enhances the reader's understanding of underlying concepts and current methods used in the field

  8. ADVANCED SULFUR CONTROL CONCEPTS

    Conventional sulfur removal in integrated gasification combined cycle (IGCC) power plants involves numerous steps: COS (carbonyl sulfide) hydrolysis, amine scrubbing/regeneration, Claus process, and tail-gas treatment. Advanced sulfur removal in IGCC systems involves typically the use of zinc oxide-based sorbents. The sulfides sorbent is regenerated using dilute air to produce a dilute SO{sub 2} (sulfur dioxide) tail gas. Under previous contracts the highly effective first generation Direct Sulfur Recovery Process (DSRP) for catalytic reduction of this SO{sub 2} tail gas to elemental sulfur was developed. This process is currently undergoing field-testing. In this project, advanced concepts were evaluated to reduce the number of unit operations in sulfur removal and recovery. Substantial effort was directed towards developing sorbents that could be directly regenerated to elemental sulfur in an Advanced Hot Gas Process (AHGP). Development of this process has been described in detail in Appendices A-F. RTI began the development of the Single-step Sulfur Recovery Process (SSRP) to eliminate the use of sorbents and multiple reactors in sulfur removal and recovery. This process showed promising preliminary results and thus further process development of AHGP was abandoned in favor of SSRP. The SSRP is a direct Claus process that consists of injecting SO{sub 2} directly into the quenched coal gas from a coal gasifier, and reacting the H{sub 2}S-SO{sub 2} mixture over a selective catalyst to both remove and recover sulfur in a single step. The process is conducted at gasifier pressure and 125 to 160 C. The proposed commercial embodiment of the SSRP involves a liquid phase of molten sulfur with dispersed catalyst in a slurry bubble-column reactor (SBCR).

  9. SCWR Concept in Canada

    AECL is designing the Canadian SCWR concept, which has evolved from the well-established pressuretube type CANDU® reactor. The Canadian SCWR is designed to produce electrical energy as the main product, plus process heat, hydrogen, industrial isotopes, and drinking water (through the desalination process) as supplementary products, all within a more compact reactor building. Another potential application of the available co-generated process heat is the extraction and refining of oil sands, which is presently achieved using co-generation with natural gas turbines and process heat. The extraction and upgrading process requires: thermal power to lower the viscosity and extract the oil; electric power for separation and refining equipment; and hydrogen gas for upgrading the oil product prior to transport. A National Program has been established in Canada to support R&D studies for the Canadian SCWR design. It covers key areas of interest (such as thermal hydraulics, safety, materials, and chemistry) to participants in the Generation-IV International Forum (GIF) SCWR designs. Results generated from the program are contributed to the GIF SCWR project management boards (PMBs). For example, heat transfer correlations have been derived using experimental data primarily obtained from fossil-plant related studies (which were started as early as 1930s. Materials and chemistry studies have evolved from operating experience of fossil-fired power plants to a) develop, and perform targeted testing of, materials for key components, in particular in-core reactor components that will be exposed to conditions not encountered in a fossil-fired boiler (such as irradiation and water radiolysis), and b) develop a suitable water chemistry to minimize corrosion and corrosion product transport.

  10. Sociological concept of morale

    2012-01-01

    Full Text Available The author first discusses the overall unity of the total normative regulation, from which it is separated in the late Roman empire the right, but only in the new century and the morale. There are analyzed the relationship between the moral and ethical reflection and Weber's distinction between pure ethics will (Gesinnungsethik and ethics of responsibility (Verantwortungsethik. The morale is determined by the good as the highest value, as a specific form of social norms but also as a kind of human behavior. These three definitions can be combined in an integrative approach. There are examined the dimensions of moral statements, subjective and objective side of morality, as well as the difference between morale and morality. A general notion of morale can not be defined in substantive but only in formal way . The formal definition is a constituent of general as well as of sociological concept of morale and it is related to morality as a social phenomenon. Its essence is to define the morale by specific norms, the characteristics of the internal and external mandatory (with the pricks of conscience as the most distinctive moral sanction and control exercised by the formal not institutionalized or diffuse society , and in consideration of morality as a social process (actions of people associated moral norms . The basic types of social moral process - being, education, functioning and changing of morale are described. There are briefly analyzed the influence of society to the morale and social function of morale, with special emphasis on the relationship between law and morale.

    We conducted a study to examine the role of cholecystokinin in feeding behavior and weight change in rats with obstructive jaundice. Daily food and water intake, body weight, and short-term food intake were determined in two groups of rats with surgically induced obstructive jaundice and in control rats. One group of rats with obstructive jaundice was given L-364,718, a selective cholecystokinin receptor antagonist. Plasma bilirubin and cholecystokinin levels were measured in each rat before and 7 days after surgery. Daily food intake and body weight were decreased in obstructive jaundice rats compared with control rats during the first week after surgery (P less than .05); however, obstructive jaundice rats treated with L-364,718 had increased food intake and body weight (P less than .05). Short-term food intake measured for 30 minutes and 120 minutes in food-deprived obstructive jaundice rats was decreased when compared with control rats (P less than .05), but the obstructive jaundice rats given L-364,718 had increased short-term food intake (P less than .05). Water intake was similar between the two groups of rats. Plasma levels of cholecystokinin and bilirubin were increased in obstructive jaundice rats with and without L-364,718 treatment (P less than .05). The results support the concept that endogenously elevated levels of plasma cholecystokinin play an important role in decreased food intake and subsequent loss of body weight in rats with obstructive jaundice.

  12. Traduire encore Bertin aujourd'hui : pourquoi faire ? Les nouvelles faces cachées de la Sémiologie Graphique

    Dhieb, Mohsen

    2018-05-01

    La « Sémiologie Graphique » de Bertin est un ouvrage majeur de la cartographie contemporaine. Cependant, dès sa parution en 1967, cet ouvrage a suscité autant d'intérêt que de méfiance : l'ouvrage n'était pas dans le « moule » de la littérature cartographique en vigueur. Pourtant, si plusieurs de ses principes et concepts fondateurs ont été adoptés, plusieurs autres ne sont pas bien passés ou n'ont pas été mis en pratique. Il y a comme un fossé entre certains énoncés théoriques de l'ouvrage et leur mise en pratique. Certaines affirmations de Bertin peuvent paraître obsolètes aujourd'hui à l'heure du numérique, comme la non prise en compte de l'aspect dynamique ou interactif de la carte. L'avènement récent des SIG, de la géomatique et des systèmes de Cartographie Assistée par Ordinateur a relégué les vieilles méthodes de traitement graphique de l'information au second rang. Dès lors pourquoi traduire encore aujourd'hui, à l'heure du numérique, la « Sémiologie Graphique » ? Justement, d'abord, parce que certains principes restent, en substance, peu connus ; plusieurs aspects demeurent encore à explorer ; certaines méthodes et techniques manuelles délaissées peuvent être revisitées et remises en marche grâce à la visualisation ; des innovations n'ont pas été expérimentées ou implémentées par les moyens numériques. Dans le monde arabe, peu de recherches se sont imprégnées de sémiologie graphique. Lors de la traduction de l'ouvrage en arabe, des points restés obscurs ont été décelés. Ce sont ces quelques idées et réflexions qui nous ont poussés à revivre cette formidable aventure.

  13. Fourth Generation Reactor Concepts

    International Nuclear Information System (INIS)

    Furtek, A.

    2008-01-01

    Concerns over energy resources availability, climate changes and energy supply security suggest an important role for nuclear energy in future energy supplies. So far nuclear energy evolved through three generations and is still evolving into new generation that is now being extensively studied. Nuclear Power Plants are producing 16% of the world's electricity. Today the world is moving towards hydrogen economy. Nuclear technologies can provide energy to dissociate water into oxygen and hydrogen and to production of synthetic fuel from coal gasification. The introduction of breeder reactors would turn nuclear energy from depletable energy supply into an unlimited supply. From the early beginnings of nuclear energy in the 1940s to the present, three generations of nuclear power reactors have been developed: First generation reactors: introduced during the period 1950-1970. Second generation: includes commercial power reactors built during 1970-1990 (PWR, BWR, Candu, Russian RBMK and VVER). Third generation: started being deployed in the 1990s and is composed of Advanced LWR (ALWR), Advanced BWR (ABWR) and Passive AP600 to be deployed in 2010-2030. Future advances of the nuclear technology designs can broaden opportunities for use of nuclear energy. The fourth generation reactors are expected to be deployed by 2030 in time to replace ageing reactors built in the 1970s and 1980s. The new reactors are to be designed with a view of the following objectives: economic competitiveness, enhanced safety, minimal radioactive waste production, proliferation resistance. The Generation IV International Forum (GIF) was established in January 2000 to investigate innovative nuclear energy system concepts. GIF members include Argentina, Brazil, Canada, Euratom, France Japan, South Africa, South Korea, Switzerland, United Kingdom and United States with the IAEA and OECD's NEA as permanent observers. China and Russia are expected to join the GIF initiative. The following six systems

    Studies of the COMET core catcher concept developed for a future PWR have been continued. The concept is based on the spreading of a core melt on a sacrificial layer and its erosion, until a subsequent addition of water from below causes a fragmentation of the melt. A porous solidification of the melt would then admit a complete flooding within a short period. (orig.)

  20. Perceived parental efficacy: concept analysis.

    Science.gov (United States)

    Montigny, Francine; Lacharité, Carl

    2005-02-01

    This paper describes a concept analysis carried out to remove some of the ambiguity surrounding the conceptual meaning of perceived parental efficacy and to distinguish it from related concepts such as parental confidence and parental competence. Constructing parental efficacy is a crucial step for family members after the birth of their first child. For some authors, perceived parental efficacy is a motor for adequate parental practices. Confusion about the definition and measurement of this concept has hindered both psychology and nursing practice and research. Concept delineation and concept clarification are required in order to further the development of the concept of perceived parental efficacy. A literature search using a variety of online databases yielded 113 articles between the years 1980 and 2000. The final sample (n=60) consisted of 30 articles from two disciplines: nursing and psychology. A content analysis of the literature was done using Rodger's evolutionary concept analysis method. Content analysis of the literature yielded four contributors to perceived parental efficacy: positive enactive mastery experiences, vicarious experiences, verbal persuasion and an appropriate physiological and affective state. Perceived parental efficacy can thus be defined as 'beliefs or judgements a parent holds of their capabilities to organize and execute a set of tasks related to parenting a child'. This conceptual analysis has allowed perceived parental efficacy to be distinguished from parental confidence and parental competence. Both nursing and psychology research, practice and education will benefit from a more precise and delineated concept.

    Meier, W.R.; Maniscalco, J.A.

    1977-07-01

    Scoping studies were initiated to identify attractive reactor concepts for producing electric power with laser fusion. Several exploratory reactor concepts were developed and are being subjected to our criteria for comparing long-range sources of electrical energy: abundance, social costs, technical feasibility, and economic competitiveness. The exploratory concepts include: a liquid-lithium-cooled stainless steel manifold, a gas-cooled graphite manifold, and fluidized wall concepts, such as a liquid lithium ''waterfall'', and a ceramic-lithium pellet ''waterfall''. Two of the major reactor vessel problems affecting the technical feasibility of a laser fusion power plant are: the effects of high-energy neutrons and cyclical stresses on the blanket structure and the effects of x-rays and debris from the fusion microexplosion on the first-wall. The liquid lithium ''waterfall'' concept is presented here in more detail as an approach which effectively deals with these damaging effects

    Opalinski, Andra S; Weglicki, Linda S; Gropper, Sareen S

    2018-01-01

    The aim of this article is to provide clarity of the concept of health habit. Using Walker and Avant's (1983; 2010) method for conducting a concept analysis, the authors identify the attributes and characteristics of health habit, its theoretical and practical application to nursing, and sample cases to further illustrate the concept. Empirical and conceptual literature was used to inform this concept analysis. Articles and one book from 1977 to 2014 were reviewed from PsycINFO, Medline, Cumulative Index to Nursing Health Literature (CINAHL), Science Direct, EBSCOhost and Web of Science. Offering a clear definition and conceptual model of health habit provide the foundation to identify/develop appropriate measures of the concept and guide further investigation of understanding the development and sustainability of healthy habits. Additional research is needed to test the conceptual relationships between health habits and outcome variables as they apply to different groups across the age continuum. © 2017 Wiley Periodicals, Inc.

    The study that we propose concerns the automatic design of static converters and especially of Uninterrupted Power Supply (UPS). The aim is the development of a tool bringing an assistance in the analysis of the specifications, the choice and design of the structure that best match the application. To realize the design of these UPS, a new approach is presented. Specifications are described in terms of input and output performances (voltage, current, ...). These data are analyzed by using design rules and methods which allows designing the input filter, the output filter, the inverter, the rectifier, etc. In practice, these rules and methods are implemented on a micro computer by use of an “expert system generator” SMECI. We present and justify the modular structure that has been installed, as well as its functioning. L'étude que nous proposons concerne la conception automatique des convertisseurs statiques et en particulier des Alimentations Sans Interruption (ASI). Le but recherché est la mise au point d'un outil apportant une aide à l'analyse du cahier des charges, au choix et au dimensionnement des structures les mieux adaptées. Pour réaliser la conception de ces ASI, une nouvelle approche est présentée. Les spécifications sont décrites par les performances recherchées au niveau des courants et des tensions à l'entrée et à la sortie. Ces données sont analysées par l'emploi de méthodes et de règles de conception permettant ainsi de dimensionner le filtre d'entrée, le filtre de sortie, l'onduleur, le redresseur, etc. Au plan pratique, ces règles et méthodes sont implantées à l'aide du “générateur de système expert” SMECI. Nous présentons et justifions la structure modulaire qui a été mise en place, ainsi que son fonctionnement.

    1981-01-01

    The influence of social isolation in rats on postsynaptic alpha 1 - and beta-adrenergic receptors, on the cAMP generating system and on the presynaptic uptake mechanism in the central noradrenergic system was examined in different brain regions. Rearing rats in isolation from the 19th day of life for 12 weeks leads in all regions to a general tendency for a reduction in 3 H-DHA binding, to an enhanced 3 H-WB4101 binding and to a decreased responsiveness of the noradrenaline sensitive cAMP generating system. These changes reach significance only in the pons-medulla-thallamusregion. Isolated rats showed an increased synaptosomal uptake of noradrenaline, most pronounced and significant in the hypothalamus. Our data provide further support for a disturbance in central noradrenergic function in isolated rats. (author)

    2017-07-01

    The aim of this article is to analyze the concept of respite care in the context of caring for a child with special healthcare needs. Respite care has often been identified as an important resource for caregivers of children with special healthcare needs. It can help provide a break from the constant demands of caregiving. A concept analysis was conducted using an evolutionary approach. The data source for the concept analysis was a review of literature addressing respite care for caregivers of children with special healthcare needs. A review of the literature was conducted and a concept model was developed using an evolutionary approach. A theoretical definition of respite care is provided and the defining attributes, related concepts, antecedents, and consequences of respite care are shown in a diagram of the concept of respite care. The conceptual model provides a framework to help nurses better understand the concept of respite care in order to educate caregivers, provide appropriate referrals, serve as providers of respite care, and advocate for policy changes related to the provision of respite care services for caregivers of children with special healthcare needs. © 2016 Wiley Periodicals, Inc.

    DeBastiani, Summer; De Santis, Joseph P

    2018-02-01

    Suicide is a significant health problem internationally. Those who complete suicide may have different behaviors and risk factors than those who attempt a non-fatal suicide. The purpose of this article is to analyze the concept of suicide lethality and propose a clear definition of the concept through the identification of antecedents, attributes, and consequences. A literature search for articles published in the English language between 1970 and 2016 was conducted using MEDLINE, the Cochrane Library, Pubmed, Psychlit, Ovid, PsycINFO, and Proquest. The bibliographies of all included studies were also reviewed to identify additional relevant citations. A concept analysis was conducted on the literature findings using six stages of Walker and Avant's method. The concept analysis differentiated between suicide, lethality, suicidal behavior, and suicide lethality. Presence of a suicide plan or a written suicide note was not found to be associated with the majority of completed suicides included in the definition of suicide lethality. There are a few scales that measure the lethality of a suicide attempt, but none that attempt to measure the concept of suicide lethality as described in this analysis. Clarifying the concept of suicide lethality encourages awareness of the possibility of different suicidal behaviors associated with different suicide outcomes and will inform the development of future nursing interventions. A clearer definition of the concept of suicide lethality will guide clinical practice, research, and policy development aimed at suicide prevention.

    Full Text Available Some problems like rapidly developing industrialization, irregular population growth, environmental pollution and to feel the impact of global warming as seriously, has been giving significant damage to the earth. People has realized that, after polluting to clean is harder than polluting of the measures to be taken before. And again people showed the sensitivity to the environment through different reactions and sanctions, took measures and created the new concepts about the enviroment. "Ethical Fashion" concept was created by the conscious and responsible individuals in the last two decades. However, that are being implemented as a concept is noticeable. Textile and fashion industry cover "Ethical Fashion"; ecological product, working conditions, fair trade and sustainable product are all in that concept. "Ethical Fashion" appeared and developed especially in United Kingdom, the USA and the other European countries. Nowadays, we may see a lot of textile and fashion designers, fabric and clothing collections, fairs and some specific courses at the universities about "Ethical Fashion". In this research contains "Ethical Fashion" concept, it's development processes and fashion designers who is working for this concept at the present time, also the main target is in this research, semtinizing "Ethical Fashion" concept.

    1987-01-01

    The Integral Fast Reactor (IFR) is an innovative liquid metal reactor concept being developed at Argonne National Laboratory. It seeks to specifically exploit the inherent properties of liquid metal cooling and metallic fuel in a way that leads to substantial improvements in the characteristics of the complete reactor system. The IFR concept consists of four technical features: (1) liquid sodium cooling, (2) pool-type reactor configuration, (3) metallic fuel, and (4) an integral fuel cycle, based on pyrometallurgical processing and injection-cast fuel fabrication, with the fuel cycle facility collocated with the reactor, if so desired. This paper gives a review of the IFR concept

    1992-01-01

    In this paper, the results of three trade-off studies of alternative concepts for performing cask maintenance for Civilian Radioactive Waste Management System casks are presented. An earlier study resulted in a recommendation that a submerged pool concept for cask internal component removal be used in the design of a Cask Maintenance Facility. The first trade-off study resulted in confirming the previous recommendation that a submerged pool concept be used rather than an isolation cell; the basis for this continued recommendation is discussed. The second study provides an evaluation of the previously proposed facility for the capability of handling an increased quantity of OCRWM casks. The third study provides a preliminary concept for adding the capability to repaint the exterior cylindrical portions of casks

    2006-01-01

    The Naval Reactors Prime Contractor Team (NRPCT) recommended the development of a gas cooled reactor directly coupled to a Brayton energy conversion system as the Space Nuclear Power Plant (SNPP) for NASA's Project Prometheus. The section of piping between the reactor outlet and turbine inlet, designated as the hot leg piping, required unique design features to allow the use of a nickel superalloy rather than a refractory metal as the pressure boundary. The NRPCT evaluated a variety of hot leg piping concepts for performance relative to SNPP system parameters, manufacturability, material considerations, and comparison to past high temperature gas reactor (HTGR) practice. Manufacturability challenges and the impact of pressure drop and turbine entrance temperature reduction on cycle efficiency were discriminators between the piping concepts. This paper summarizes the NRPCT hot leg piping evaluation, presents the concept recommended, and summarizes developmental issues for the recommended concept

    Ma, Shu-Ching; Wang, Hsiu-Hung; Chen, Jih-Yuan

    2011-08-01

    Workplace bullying is a complicated and imprecise concept. Research findings have highlighted it as an important issue in the nursing environment worldwide. Workplace bullying arises due to malfunctions in workplace organizational and cultural related antecedents and manifests in various forms. Many studies have reported that nurses experiencing workplace bullying face increased levels of physical, psychological and social distress, may adopt suicidal thoughts and negativity towards the nursing profession, and may even abandon the nursing profession completely. Although a large number of papers have discussed the antecedents, forms and interventions related to workplace bullying, there has yet been no systematic concept analysis of workplace bullying. This paper applied Walker and Avant's concept analysis process to verify concept definitions, identify defining attributes, antecedents, and consequences, and provide examples of model, borderline, and contrary cases. Findings can help nursing administrators understand and clarify the meaning of workplace bullying in order to take appropriate measures to improve the working environment for nursing professionals.

    2016-12-01

    Full Text Available Mediatization has become increasingly a key concept, fundamental, essential to describe the present and the history of media and communicative change taking place. Thus, it became part of a whole, one can not see them as a separate sphere. In this perspective, the media coverage is used as a concept to describe the process of expansion of the different technical means and consider the interrelationships between the communicative change, means and sociocultural change. However, although many researchers use the concept of mediatization, each gives you the meaning that best suits your needs. Thus, the concept of media coverage is treated with multiple voices. This paper discusses this problem and present a preliminary pre-position on the matter.

  6. Care partner: A concept analysis.

    Science.gov (United States)

    Bennett, Paul N; Wang, Wei; Moore, Mel; Nagle, Cate

    The use of the term care partner has increased, particularly in the chronic disease literature; however, the concept has not been well defined. The purpose of this concept analysis was to define and assist nurses to better understand the concept of care partner. The method by Walker and Avant was used for this literature-based concept analysis. Care partnering includes providing assistance to an individual with a health condition to meet their self-care deficits, the commitment to a care partner relationship, and the recognition that people with self-care deficits are care partners contributing to their own care. Emphasizing the care partner dyad in nursing may contribute to improved patient care outcomes both in the acute and chronic settings. It is recommended that nurses view the person with the condition as a contributor and partner in their own care in the context of a larger care partnership. Copyright © 2016 Elsevier Inc.

  7. Dominant lethals following administration of tritium (THO) to rat males

    International Nuclear Information System (INIS)

    Yagova, A.; Baev, I.; Bajrakova, A.

    1976-01-01

    Adult rat males were given a single intraperitoneal tritium (THO) injection at 0,01 or 0,001 mCi/g body weight (1/100 or 1/1000 of LDsub(50/30), respectively). Twelve days after treatment each male was mated to 3-5 intact females, and the latter were replaced by fresh ones every 12 following days over a 120-day period. Mated females were killed to score conceptions, corpora lutea, and live and dead embryos. Estimations were made of F 1 prenatal death rate (according to Bateman, 1958) and the frequency of induction of dominant lethal mutations (according to Roehrborn, 1970). The results observed indicated paternal exposure to tritium (THO) to produce dominant lethals both in pre- and post-meiotic germ cells in the rat. The extent of the genetic damage studied was found to depend on the amount of activity administered as well as on the time interval between treatment and conception. (author)

    2011-01-01

    NASA's Exploration Technology Development and Demonstration Program has proposed plans for a series of three sub-scale flight tests at Earth for supersonic retropropulsion, a candidate decelerator technology for future, high-mass Mars missions. The first flight test in this series is intended to be a proof-of-concept test, demonstrating successful initiation and operation of supersonic retropropulsion at conditions that replicate the relevant physics of the aerodynamic-propulsive interactions expected in flight. Five sub-scale flight test article concepts, each designed for launch on sounding rockets, have been developed in consideration of this proof-of-concept flight test. Commercial, off-the-shelf components are utilized as much as possible in each concept. The design merits of the concepts are compared along with their predicted performance for a baseline trajectory. The results of a packaging study and performance-based trade studies indicate that a sounding rocket is a viable launch platform for this proof-of-concept test of supersonic retropropulsion.

  12. Spatial Modernist Architectural Artistic Concepts

    Gudkova, T. V.; Gudkov, A. A.

    2017-11-01

    The development of a single spatial modernist conception had continued until the middle of the twentieth century. The first authors who proposed the new conceptual solutions of an architectural space that had the greatest impact on the further development of architecture were Le Corbusier, Frank Lloyd Wright, Mies van der Rohein. They embodied different approaches within the common modernist spatial concept using the language of morphological, symbolic and phenomenological descriptions of space. The concept was based on the simplification of functional links, integration of internal architectural space with the environment due to the vanishing of boundaries between them and expansion of their interrelation. Le Corbusier proposed a spatio-temporal concept based on the movement and tempo-rhythmics of the space “from inside to outside.” Frank Lloyd Wright proposed the concept of integral space where inner and outer spaces were the parts of a whole. Mies van der Rohein was the author of the universal space concept in which the idea of the “dissolution” of the inner space in the outer space was embodied.

  13. The concept of collaborative health.

    Science.gov (United States)

    Sandberg, Håkan

    2010-11-01

    Based on empirical research about teamwork in human service organizations in Sweden, the concept of collaborative health (CH) encapsulates the physical, psychological and social health resources the individual uses in teamwork; resources which at the same time are influenced by the teamwork. My argument built on empirical research leading up to identifying and defining the core concept in this article, is that teamwork affects team members' health and this in turn affects the teamwork and its outcome. In this paper collaborative health is viewed from a social constructionism perspective and discussed in relation to earlier concepts developed in social psychology and working life research, including psychosocial stress and burnout. The paper also introduces the concept of functional synergy, which in this context is defined as the simultaneous presence of sharp goal-orientation and synergy in teamwork. The need for a holistic team theory is emphasized as a tool in research on teamwork. Such a theory relies on identifying sound and illuminating constituent concepts. I suggest that collaborative health could be a useful concept for better understanding the complex collaborative and co-operative teamwork of human service organizations of today.

  14. Maternal sensitivity: a concept analysis.

    2008-11-01

    The aim of this paper is to report a concept analysis of maternal sensitivity. Maternal sensitivity is a broad concept encompassing a variety of interrelated affective and behavioural caregiving attributes. It is used interchangeably with the terms maternal responsiveness or maternal competency, with no consistency of use. There is a need to clarify the concept of maternal sensitivity for research and practice. A search was performed on the CINAHL and Ovid MEDLINE databases using 'maternal sensitivity', 'maternal responsiveness' and 'sensitive mothering' as key words. The searches yielded 54 records for the years 1981-2007. Rodgers' method of evolutionary concept analysis was used to analyse the material. Four critical attributes of maternal sensitivity were identified: (a) dynamic process involving maternal abilities; (b) reciprocal give-and-take with the infant; (c) contingency on the infant's behaviour and (d) quality of maternal behaviours. Maternal identity and infant's needs and cues are antecedents for these attributes. The consequences are infant's comfort, mother-infant attachment and infant development. In addition, three positive affecting factors (social support, maternal-foetal attachment and high self-esteem) and three negative affecting factors (maternal depression, maternal stress and maternal anxiety) were identified. A clear understanding of the concept of maternal sensitivity could be useful for developing ways to enhance maternal sensitivity and to maximize the developmental potential of infants. Knowledge of the attributes of maternal sensitivity identified in this concept analysis may be helpful for constructing measuring items or dimensions.

    As nursing education struggles to address a rapidly changing health care system, overcrowded curricula, and an increased focus on clinical reasoning skills, many programs have adopted or transitioned to concept-based curricula (CBCs), which are structured around key concepts and exemplars. Despite CBC's promised benefits, the process of developing a CBC framework may pose a challenge to programs. To address this barrier, a national study was conducted to develop a representative list of concepts and exemplars. This initiative expands on prior work by suggesting a leveled approach to positioning exemplars within a curricular sequence.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    1978-01-01

    The effect of irradiation of x-ray to developing rat mandible in the gestation stage was focused on the study of mandible development and the side effect of x-ray irradiation. The author studied the effect of x-ray irradiation with the gestated rat and their offsprings. 100 rads, 200 rads, 300 rads and 400 rads of x-ray was irradiated in regular order schematically at the lower left abdomen of gestated rat. 18 1/2 days after conception, their offsprings were sacrificed and examined their developing mandible with histological findings. The results were as followed. 1. In the 100-200 rads irradiated rat offsprings, bony trabeclulation was revealed irregular shape. In combine with this finding, osteoblast and fibroblast were appeared shrunken of their nucleus and location of eccentric position. 2. In the 300-400 rads irradiated rat offsprings, decrease of fibroblast and osteoblast appearance in the periosteum were prominently observed and empty lacunae were frequently appeared in their bone matrix. 3. The advent of osteoclast and resorption of cortical bone were appeared in proportion to increasing of x-ray irradiation.

  19. Calling to Nursing: Concept Analysis.

    Science.gov (United States)

    Emerson, Christie

    The aims of this article are (a) to analyze the concept of a calling as it relates nursing and (b) to develop a definition of calling to nursing with the detail and clarity needed to guide reliable and valid research. The classic steps described by Walker and Avant are used for the analysis. Literature from several disciplines is reviewed including vocational psychology, Christian career counseling, sociology, organizational management, and nursing. The analysis provides an operational definition of a calling to nursing and establishes 3 defining attributes of the concept: (a) a passionate intrinsic motivation or desire (perhaps with a religious component), (b) an aspiration to engage in nursing practice, as a means of fulfilling one's purpose in life, and (c) the desire to help others as one's purpose in life. Antecedents to the concept are personal introspection and cognitive awareness. Positive consequences to the concept are improved work meaningfulness, work engagement, career commitment, personal well-being, and satisfaction. Negative consequences of having a calling might include willingness to sacrifice well-being for work and problems with work-life balance. Following the concept analysis, philosophical assumptions, contextual factors, interdisciplinary work, research opportunities, and practice implications are discussed.

  20. Comfort measures: a concept analysis.

    Science.gov (United States)

    Oliveira, Irene

    2013-01-01

    Reference to the concept of comfort measures is growing in the nursing and medical literature; however, the concept of comfort measures is rarely defined. For the comfort work of nurses to be recognized, nurses must be able to identify and delineate the key attributes of comfort measures. A concept analysis using Rodgers' evolutionary method (2000) was undertaken with the goal of identifying the core attributes of comfort measures and thereby clarifying this concept. Health care literature was accessed from the CINAHL and PubMed databases. No restrictions were placed on publication dates. Four main themes of attributes for comfort measures were identified during the analysis. Comfort measures involve an active, strategic process including elements of "stepping in" and "stepping back," are both simple and complex, move from a physical to a holistic perspective and are a part of supportive care. The antecedents to comfort measures are comfort needs and the most common consequence of comfort measures is enhanced comfort. Although the concept of comfort measures is often associated with end-of-life care, this analysis suggests that comfort measures are appropriate for nursing care in all settings and should be increasingly considered in the clinical management of patients who are living with multiple, chronic comorbidities.

    In the context of mental disorders sensory overload is a widely described phenomenon used in conjunction with psychiatric interventions such as removal from stimuli. However, the theoretical foundation of sensory overload as addressed in the literature can be described as insufficient and fragmentary. To date, the concept of sensory overload has not yet been sufficiently specified or analyzed. The aim of the study was to analyze the concept of sensory overload in mental health care. A literature search was undertaken using specific electronic databases, specific journals and websites, hand searches, specific library catalogues, and electronic publishing databases. Walker and Avant's method of concept analysis was used to analyze the sources included in the analysis. All aspects of the method of Walker and Avant were covered in this concept analysis. The conceptual understanding has become more focused, the defining attributes, influencing factors and consequences are described and empirical referents identified. The concept analysis is a first step in the development of a middle-range descriptive theory of sensory overload based on social scientific and stress-theoretical approaches. This specification may serve as a fundament for further research, for the development of a nursing diagnosis or for guidelines. © 2017 Australian College of Mental Health Nurses Inc.

    Holland, Kathlyn; Middleton, Lyn; Uys, Leana

    2012-03-01

    Professional confidence is a concept that is frequently used and or implied in occupational therapy literature, but often without specifying its meaning. Rodgers's Model of Concept Analysis was used to analyse the term "professional confidence". Published research obtained from a federated search in four health sciences databases was used to inform the concept analysis. The definitions, attributes, antecedents, and consequences of professional confidence as evidenced in the literature are discussed. Surrogate terms and related concepts are identified, and a model case of the concept provided. Based on the analysis, professional confidence can be described as a dynamic, maturing personal belief held by a professional or student. This includes an understanding of and a belief in the role, scope of practice, and significance of the profession, and is based on their capacity to competently fulfil these expectations, fostered through a process of affirming experiences. Developing and fostering professional confidence should be nurtured and valued to the same extent as professional competence, as the former underpins the latter, and both are linked to professional identity.

    2016-06-01

    Exploring the concept of ethical competence in the context of healthcare is essential as it pertains to better quality of care. The concept still lacks a comprehensive definition covering the aspects of ethical expertise, ethical knowledge and action of a health professional. This article aims to report an analysis of the concept of ethical competence. A modified strategy suggested by Walker and Avant was used to analyse the concept. As a result, the concept of ethical competence can be defined in terms of character strength, ethical awareness, moral judgement skills and willingness to do good. Virtuous professional, experience of a professional, human communication, ethical knowledge and supporting surroundings in the organisation can be seen as prerequisites for ethical competence. Ethical competence results in the best possible solutions for the patient, reduced moral distress at work and development and democratisation of society. The results of the analysis establish a basis for an instrument to evaluate health professionals' ethical competence. It will guide educators, as well as managers in healthcare, to support the development of ethical conduct in healthcare. © The Author(s) 2015.

En 1991, 1992 et 1994, des séries de plongées furent organisées par le Ministère de la Culture, avec la participation de JEAN COURTIN, préhistorien et plongeur. D’autres recherches furent reprises dernièrement, en 2002 et 2003, par les cosignataires de l’article.La localisation extraordinaire de l’entrée de cette caverne est due à la montée du niveau de la mer après la fin de la dernière glaciation. Au maximum glaciaire, il y a 20.000 ans, la mer se trouvait 130 mètres plus bas qu’actuellement et la ligne de rivage était à 5 kilomètres de là.Les parois de toutes les galeries et salles submergées ont été corrodées et aucune peinture ni gravure n’y subsistent. L’art découvert se trouve dans des salles supérieures restées hors d’eau.

  10. Building concepts against airplane crash

    International Nuclear Information System (INIS)

    Henkel, F.O.; Woelfel, H.

    1984-01-01

    In Germany safety related buildings of nuclear facilities as well as their equipment are to be designed against airplane crash. While the safety of the structure itself can always be guaranteed by structural means, the induced vibrations may cause severe problems for the equipment. Considerable effort was expended in recent years to comprehend the load case airplane crash in a more exact manner and to evaluate reasonable floor response spectra. Besides this analytical effort, investigations are cited to minimize the induced vibrations by new structural concepts. The present paper gives a survey concerning the development of structural concepts, culminating in the double shell structures that are state of the art today. Then the idea of spring supports, as it is known for the aseismic foundation of buildings, is further developed to a new spring concept which reduces the induced vibrations in an optimum way in the load case airplane crash and which additionally isolates earthquake vibrations.

    The purpose of this study was to analyze and clarify the meaning of the concept, assertiveness. This study used Walker and Avant's process of concept analysis. 1. Attributes of assertiveness were defined as 1) Self-esteem 2) Comprehension to others 3) Clarification of the subject 4) Verbal communication 5) Non-verbal communication. 2. The antecedents of assertiveness consist of these facts 1) The occurrence of a conflict situation 2) The occurrence of will to stick to one's opinions. 3. There are consequences occurring as a result of assertiveness 1) Positive self-confidence 2) Increased comprehension or consideration to others 3) Expand of mutual respect 4) Maintenance of continuously cooperative relationship with each other 5) Output of acceptable results to each other. Assertiveness is a core human behavior and is key to interpersonal relationships. Using the components of the concept of assertiveness, many conflicts in a nursing situation can be effectively prevented.

    HTS components require that low-cost, reliable cooling systems be used. There are no general solutions to such systems. Any cooling concept has to be tailored to the specific requirements of a system. The following has to he taken into consideration when designing cooling concepts: - cooling temperature - constancy and controllability of the cooling temperature - cooling load and refrigerating capacity - continuous or discontinuous mode - degree of automation - full serviceability or availability before evacuation -malfunctions caused by microphonic, thermal or electromagnetic effects -stationary or mobile application - investment and operating costs (orig.)

    Full Text Available Physics, at the various stages of knowledge, presents itself as an objective description of the natural world, and makes use, for this purpose, of rational concepts, proposed as universal. However, these concepts are built by human thought in particular subjective and historical situations, and are submitted to transformation processes. Is it possible to conciliate these two points of views, the objective and the relative ones? And how to conceive such transformations, unclear the sign of intelligibility, of this science and of history as well?

    Statistical Concepts consists of the last 9 chapters of An Introduction to Statistical Concepts, 3rd ed. Designed for the second course in statistics, it is one of the few texts that focuses just on intermediate statistics. The book highlights how statistics work and what they mean to better prepare students to analyze their own data and interpret SPSS and research results. As such it offers more coverage of non-parametric procedures used when standard assumptions are violated since these methods are more frequently encountered when working with real data.

    Wendler, M Cecilia; Kirkbride, Geri; Wade, Kristen; Ferrell, Lynne

    2013-01-01

    BACKGROUND/CONCEPTUAL FRAMEWORK: Little is known about which approaches facilitate adoption and sustainment of evidence-based practice change in the highly complex care environments that constitute clinical practice today. The purpose of this article was to complete a concept analysis of translational research using a modified Walker and Avant approach. DESIGN/DATA COLLECTION: Using a rigorous and thorough review of the recent health care literature generated by a deep electronic search from 2004-2011, 85 appropriate documents were retrieved. Close reading of the articles by three coresearchers yielded an analysis of the emerging concept of translational research. Using the iterative process described by Walker and Avant, a tentative definition of the concept of translational research, along with antecedents and consequences were identified. Implications for health care professionals in education, practice, and research are offered. Further research is needed to determine the adequacy of the definition, to identify empirical referents, and to guide theory development. The study resulted in a theoretical definition of the concept of translational research, along with identification of antecedents and consequences and a description of an ideal or model case to illustrate the definition. Implications for practice and education include the importance of focusing on translational research approaches that may reduce the research-practice gap in health care, thereby improving patient care delivery. Research is needed to determine the usefulness of the definition in health care clinical practice.

    2015-01-01

    The purpose of this analysis is to examine and clarify the concept of nurses' happiness (NH), understand the different uses of the concept, explore the conditions that foster it, and consider the consequences of NH, including the phenomena that emerge as a result of NH occurrence. The author utilizes Walker and Avant's eight-stage concept analysis. Computer and manual searches were conducted of articles in the English language addressing NH from 1990 to present. EBSCO and PubMed are the electronic databases used to access literature for this paper. For both databases, the researcher has examined this new term by splitting the term nurses' happiness into its two root words, namely nurses and happiness. An inductive analysis of articles produced descriptive themes. Definitions of happiness and NH are analyzed. Antecedents, attributes, and consequences of NH are described. Model, borderline, contrary, and related cases for NH are also identified. This concept analysis helps in the understanding of the definition of NH, the attributes that contribute to the occurrence of NH in clinical practice, as well as the consequences of NH, and how it should be measured from a nursing perspective.

  13. Regulatory perspectives of concept assessment

    International Nuclear Information System (INIS)

    Flavelle, Peter A.

    1987-09-01

    The Atomic Energy Control Board is the head agency for the regulatory review of the Assessment of the Canadian Concept for Nuclear Fuel Waste Disposal being done by Atomic Energy of Canada Limited and Ontario Hydro. This paper describes the regulatory perspective of how the Concept Assessment could demonstrate the feasibility of a disposal conforming to regulatory requirements. The long-term aspects of Concept Assessment encourage the use of various predictive techniques for different time scales. Each technique will have a different potential for establishing confidence in the predictions. The predicted performance of a facility during operation should have a very high confidence, as it can be based on standard engineering calculations and the predictions can be validated later by monitoring during operation. The predictions of the transient period following closure of the facility should achieve a medium level of confidence, since they can be based on extrapolations of predictions of operational performance, using models that can be calibrated with monitoring data and with averaged input data derived from natural analog studies. Predictions based on fundamental processes will have a medium level of confidence when made to intermediate times after closure. Long-term predictions using generic or typical input data or Monte Carlo calculations of simplified models will have the least confidence and yet they can still contribute to the confidence that the disposal concept will conform to regulatory requirements

    Llanque, Sarah; Savage, Lynette; Rosenburg, Neal; Caserta, Michael

    2016-01-01

    The aim of this article was to analyze the concept of caregiver stress in the context of caring for a person with Alzheimer's disease and related dementias. Currently, there are more than 15 million unpaid caregivers for persons suffering from Alzheimer's disease and related dementias. This unpaid care can be stressful for caregivers due to the chronic nature of the disease process, as well as other factors. The paper incorporates the modified method of Wilson's concept analysis procedure to analyze the concept of caregiver stress. A review of the literature was undertaken using the Cumulative Index to Nursing and Allied Health Literature, Google Scholar, and PubMed. A theoretical definition of caregiver stress is provided, and the defining attributes, related concepts, antecedents, and consequences of caregiver stress are proposed, and case studies are presented. The analysis demonstrates that caregiver stress is the unequal exchange of assistance among people who stand in close relationship to one another, which results in emotional and physical stress on the caregiver. Implications for future nursing research and practice conclude the paper. © 2014 Wiley Periodicals, Inc.

    Abolfazl Vagharseyyedin, Seyyed

    2015-01-01

    This study aimed to describe the meaning of the concept 'workplace incivility' and promote consistency in its application in nursing research and practice. The methodology introduced by Walker and Avant was used to analyze this concept. A total number of 50 studies that had essentially addressed the concept of incivility in employees' work environment was selected. Ambiguous intent, violation of mutual respect, low intensity and lack of physical assault were identified as the defining attributes of workplace incivility. The necessary antecedent of workplace incivility consisted of the presence of two or more people, with one or more as the source of the incivility, and another or others as its target in the workplace. Moreover, certain individual and organisational factors were the potential antecedents of workplace incivility. Possible negative outcomes for victims, witnesses, organisations, society and perpetrators of such behaviours, such as increased cost for the organisation, reduced citizenship performance, psychological distress and anxiety were identified as outcomes of workplace incivility. Results of the current concept analysis can guide nurse managers to design interventions so that the occurrence of workplace incivility can be reduced. Further studies can focus on testing the psychometric properties of the existing workplace incivility scales, especially uncivil behaviours experienced by nurses across different societies or cultures.

  2. Ausubel's understanding of concept development

    Directory of Open Access Journals (Sweden)

    Janković Aleksandar P.

    2015-01-01

    Full Text Available This paper presents one of relatively new cognitivistic learning and cognition theories - the theory by American psychologist David Ausubel. We consider this theory to be very usable for teaching beginners or for cognition process. It is of utmost importance that first or elementary concepts concerning natural and social phenomena a pupil aquires need to be accurate, understandable and properly connected in a cause-effect sequence of conceptual systems so that items of knowledge aquired can be stable and usable. For correct understanding of Ausubel's claims concerning processes and procedures involved in the acquisition of elementary concepts, which is central to this investigation, it is necessary to address problems and questions concerning the following: the process of aquisition or construction of first concepts; how to base verbal learning; how is subsuming achieved, that is connecting of new and previously acquired concepts; what is the relation of this theory with other cognitivistic theories of learning, and, finally, what are critical views or evalutions which can make this theory truly productive in relation to teaching.

  3. Neural Representations of Physics Concepts.

    Mason, Robert A; Just, Marcel Adam

    2016-06-01

    We used functional MRI (fMRI) to assess neural representations of physics concepts (momentum, energy, etc.) in juniors, seniors, and graduate students majoring in physics or engineering. Our goal was to identify the underlying neural dimensions of these representations. Using factor analysis to reduce the number of dimensions of activation, we obtained four physics-related factors that were mapped to sets of voxels. The four factors were interpretable as causal motion visualization, periodicity, algebraic form, and energy flow. The individual concepts were identifiable from their fMRI signatures with a mean rank accuracy of .75 using a machine-learning (multivoxel) classifier. Furthermore, there was commonality in participants' neural representation of physics; a classifier trained on data from all but one participant identified the concepts in the left-out participant (mean accuracy = .71 across all nine participant samples). The findings indicate that abstract scientific concepts acquired in an educational setting evoke activation patterns that are identifiable and common, indicating that science education builds abstract knowledge using inherent, repurposed brain systems. © The Author(s) 2016.

  4. The concept of work ability.

    Science.gov (United States)

    Tengland, Per-Anders

    2011-06-01

    The concept of "work ability" is central for many sciences, especially for those related to working life and to rehabilitation. It is one of the important concepts in legislation regulating sickness insurance. How the concept is defined therefore has important normative implications. The concept is, however, often not sufficiently well defined. AIM AND METHOD The objective of this paper is to clarify, through conceptual analysis, what the concept can and should mean, and to propose a useful definition for scientific and practical work. RESULTS Several of the defining characteristics found in the literature are critically scrutinized and discussed, namely health, basic standard competence, occupational competence, occupational virtues, and motivation. These characteristics are related to the work tasks and the work environment. One conclusion is that we need two definitions of work ability, one for specific jobs that require special training or education, and one for jobs that most people can manage given a short period of practice. Having work ability, in the first sense, means having the occupational competence, the health required for the competence, and the occupational virtues that are required for managing the work tasks, assuming that the tasks are reasonable and that the work environment is acceptable. In the second sense, having work ability is having the health, the basic standard competence and the relevant occupational virtues required for managing some kind of job, assuming that the work tasks are reasonable and that the work environment is acceptable. CONCLUSION These definitions give us tools for understanding and discussing the complex, holistic and dynamic aspects of work ability, and they can lay the foundations for the creation of instruments for evaluating work ability, as well as help formulate strategies for rehabilitation.

  5. Compound process fuel cycle concept

    International Nuclear Information System (INIS)

    Ikegami, Tetsuo

    2005-01-01

    Mass flow of light water reactor spent fuel for a newly proposed nuclear fuel cycle concept 'Compound Process Fuel Cycle' has been studied in order to assess the capacity of the concept for accepting light water reactor spent fuels, taking an example for boiling water reactor mixed oxide spent fuel of 60 GWd/t burn-up and for a fast reactor core of 3 GW thermal output. The acceptable heavy metal of boiling water reactor mixed oxide spent fuel is about 3.7 t/y/reactor while the burn-up of the recycled fuel is about 160 GWd/t and about 1.6 t/y reactor with the recycled fuel burn-up of about 300 GWd/t, in the case of 2 times recycle and 4 times recycle respectively. The compound process fuel cycle concept has such flexibility that it can accept so much light water reactor spent fuels as to suppress the light water reactor spent fuel pile-up if not so high fuel burn-up is expected, and can aim at high fuel burn-up if the light water reactor spent fuel pile-up is not so much. Following distinctive features of the concept have also been revealed. A sort of ideal utilization of boiling water reactor mixed oxide spent fuel might be achieved through this concept, since both plutonium and minor actinide reach equilibrium state beyond 2 times recycle. Changes of the reactivity coefficients during recycles are mild, giving roughly same level of reactivity coefficients as the conventional large scale fast breeder core. Both the radio-activity and the heat generation after 4 year cooling and after 4 times recycle are less than 2.5 times of those of the pre recycle fuel. (author)

  6. Promissory Concept of medical education

    Yuriy V. Voronenko

    2015-01-01

    Full Text Available Continuing medical education (CME is a dynamic system, where distance learning is an important component. In this article, we posit the Promissory Concept of distance learning. The central principle upon which this methodology is based is that the doctor can be located in any place where the information needed for his or her practice is easily available to the patient and where the doctor is able to monitor the development of his or her knowledge and practical skills, and is able to build his or her educational record of accomplishment. The Promissory Concept combines the availability of existing online opportunities with professional self-development which can be put to the test by an external supervisor (a professor or curator, who in turn will be able to identify existing advantages in knowledge, as well as those requiring further improvement, thus helping the learner's professional development. This approach was introduced to general practitioners and nephrologists practising in Ukraine in 2013. From 2014, the Promissory Concept has been associated with the Renal Eastern Europe Nephrology Academy's (REENA annual CME course, which has been accredited by ERA-EDTA (European Renal Association–European Dialysis and Transplant Association for the past 8 years. REENA is controlled by the state organisation of postgraduate education – Shupyk National Medical Academy of Postgraduate Education. The Promissory Concept is supported by printed educational material in the scientific medical Ukrainian journal Kidneys, which is registered in scientific databases (as a Google scholar, etc.. An important characteristic of the Promissory Concept is the active involvement of doctors, who give constructive feedback on the programme. This feedback contributes to the content of the CME learning activity, as well as enhancing compliance in participation. As a result, it helps create motivated adherence and improved professional development.

    2010-07-01

    The cognitive architecture of concept is a specific structure consisting of the concept core, concept periphery, the semantic frame as the meaning and the sense of the concept, and the relations among all components of this structure. The model of the cognitive architecture of scientific and common concepts is a conceptual meta-model built upon Vygotsky's concept theory, Fillmore's semantic frame, semantic triangle, on widespread ideas of the structuring of conceptual systems, and the Hestenes' Modeling Theory. The method of semantic mapping of concepts flowing from the model is designed.

  17. SUSTAINABLE DEVELOPMENT, A MULTIDIMENSIONAL CONCEPT

    Directory of Open Access Journals (Sweden)

    TEODORESCU ANA MARIA

    2015-06-01

    Full Text Available Sustainable development imposed itself as a corollary of economic term "development". Sustainable development is meant to be the summation of economic, environmental and social considerations for the present and especially for the future. The concept of sustainable development plays an important role in european and global meetings since 1972, the year it has been set for the first time. Strategies necessary to achieve the objectives of sustainable development have been developed, indicators meant to indicate the result of the implementation of policies have been created, national plans were oriented towards achieving the proposed targets. I wanted to highlight the multidimensional character of the concept of sustainable development. Thus, using specialized national and international literature, I have revealed different approaches of one pillar to the detriment of another pillar depending on the specific field. In the different concepts of sustainable development, the consensus is undoubtedly agreed on its components: economic, social, environmental. Based on this fact, the concept of sustainability has different connotations depending on the specific content of each discipline: biology, economics, sociology, environmental ethics. The multidimensional valence of sustainable development consists of three pillars ability to act together for the benefit of present and future generations. Being a multidimensional concept, importance attached to a pillar over another is directed according to the particularities of each field: in economy profit prevails, in ecology care of natural resources is the most important, the social aims improving human living conditions. The challenge of sustainable development is to combine all the economic, environmental and social benefits and the present generation to come. Ecological approach is reflected in acceptance of limited natural resources by preserving natural capital. In terms of the importance of

  18. Transportation System Concept of Operations

    2006-08-16

    The Nuclear Waste Policy Act of 1982 (NWPA), as amended, authorized the DOE to develop and manage a Federal system for the disposal of SNF and HLW. OCRWM was created to manage acceptance and disposal of SNF and HLW in a manner that protects public health, safety, and the environment; enhances national and energy security; and merits public confidence. This responsibility includes managing the transportation of SNF and HLW from origin sites to the Repository for disposal. The Transportation System Concept of Operations is the core high-level OCRWM document written to describe the Transportation System integrated design and present the vision, mission, and goals for Transportation System operations. By defining the functions, processes, and critical interfaces of this system early in the system development phase, programmatic risks are minimized, system costs are contained, and system operations are better managed, safer, and more secure. This document also facilitates discussions and understanding among parties responsible for the design, development, and operation of the Transportation System. Such understanding is important for the timely development of system requirements and identification of system interfaces. Information provided in the Transportation System Concept of Operations includes: the functions and key components of the Transportation System; system component interactions; flows of information within the system; the general operating sequences; and the internal and external factors affecting transportation operations. The Transportation System Concept of Operations reflects OCRWM's overall waste management system policies and mission objectives, and as such provides a description of the preferred state of system operation. The description of general Transportation System operating functions in the Transportation System Concept of Operations is the first step in the OCRWM systems engineering process, establishing the starting point for the lower

    Existing mathematical theory interprets the concept of standard deviation as the dispersion degree. Therefore, in measurement theory, both uncertainty concept and precision concept, which are expressed with standard deviation or times standard deviation, are also defined as the dispersion of measurement result, so that the concept logic is tangled. Through comparative analysis of the standard deviation concept and re-interpreting the measurement error evaluation principle, this paper points o...

  1. Pets, Purity and Pollution: Why Conventional Models of Disease Transmission Do Not Work for Pet Rat Owners.

    Science.gov (United States)

    Robin, Charlotte; Perkins, Elizabeth; Watkins, Francine; Christley, Robert

    2017-12-07

    In the United Kingdom, following the emergence of Seoul hantavirus in pet rat owners in 2012, public health authorities tried to communicate the risk of this zoonotic disease, but had limited success. To explore this lack of engagement with health advice, we conducted in-depth, semi-structured interviews with pet rat owners and analysed them using a grounded theory approach. The findings from these interviews suggest that rat owners construct their pets as different from wild rats, and by elevating the rat to the status of a pet, the powerful associations that rats have with dirt and disease are removed. Removing the rat from the contaminated outside world moves their pet rat from being 'out of place' to 'in place'. A concept of 'bounded purity' keeps the rat protected within the home, allowing owners to interact with their pet, safe in the knowledge that it is clean and disease-free. Additionally, owners constructed a 'hierarchy of purity' for their pets, and it is on this structure of disease and risk that owners base their behaviour, not conventional biomedical models of disease.

    Typical synthetic aperture RADAR (SAR) imaging employs a co-located RADAR transmitter and receiver. Bistatic SAR imaging separates the transmitter and receiver locations. A bistatic SAR configuration allows for the transmitter and receiver(s) to be in a variety of geometric alignments. Sandia National Laboratories (SNL) / New Mexico proposed the deployment of a ground-based RADAR receiver. This RADAR receiver was coupled with the capability of digitizing and recording the signal collected. SNL proposed the possibility of creating an image of targets the illuminating SAR observes. This document describes the developed hardware, software, bistatic SAR configuration, and its deployment to test the concept of a ground-based bistatic SAR. In the proof-of-concept experiments herein, the RADAR transmitter will be a commercial SAR satellite and the RADAR receiver will be deployed at ground level, observing and capturing RADAR ground/targets illuminated by the satellite system.

  6. The Nordic concept of 'faellesskab'.

    Science.gov (United States)

    Riis, P

    1991-01-01

    The complex of cultural, political and societal affiliations, both in a historic and a contemporary perspective, is expressed by a special term in the Nordic languages, 'faellesskab', often with the addition of 'folkelig', as 'folkeligt faellesskab', where 'folkelig' means of the people. No corresponding term exists in English. For medical ethics the concept 'faellesskab', or whatever wording is chosen to serve the semantics of this term, is vital. In research ethics and clinical decision-making complex ethical analyses and normative evaluations are necessary. They cannot be based solely on moral relativism, whether being based on results of opinion polls or on a widespread 'every man minds his own business' concept. 'Faellesskab' possesses the necessary base of common values. PMID:2033630

    1991-01-01

    The needs for, and merits of, a new concept for the safety assessment and approval of shipments of radioactive materials is introduced and discussed. The purpose of the new concept is to enable and encourage integration of analysis and review of transport safety with similar safety analysis and review of the handling operations involving the radioactive material at the despatching and receiving ends of a shipment. Safety contributing elements or functions of the means of transport (the Transport System) can thus readily be taken into account in the assessment. The objective is to avoid constraints -experienced or potential - introduced by the package functional provisions contained in the transport regulations, whilst maintaining safety during transport, as well as during facility handling operations, at least at the level at the level currently established.

    This project will develop, integrate, test, and evaluate Habitation Systems that will be utilized as technology testbeds and will advance NASA's understanding of alternative deep space mission architectures, requirements, and operations concepts. Rapid prototyping and existing hardware will be utilized to develop full-scale habitat demonstrators. FY 2014 focused on the development of a large volume Space Launch System (SLS) class habitat (Skylab Gen 2) based on the SLS hydrogen tank components. Similar to the original Skylab, a tank section of the SLS rocket can be outfitted with a deep space habitat configuration and launched as a payload on an SLS rocket. This concept can be used to support extended stay at the Lunar Distant Retrograde Orbit to support the Asteroid Retrieval Mission and provide a habitat suitable for human missions to Mars.

  9. Concept Acquisition and Experiential Change

    Directory of Open Access Journals (Sweden)

    William S. Robinson

    2014-12-01

    Full Text Available Many have held the Acquisition of Concepts Thesis (ACT that concept acquisition can change perceptual experience. This paper explains the close relation of ACT to ADT, the thesis that acquisition of dispositions to quickly and reliably recognize a kind of thing can change perceptual experience. It then states a highly developed argument given by Siegel (2010 which, if successful, would offer strong support for ADT and indirect support for ACT. Examination of this argument, however, reveals difficulties that undermine its promise. Distinctions made in this examination help to clarify an alternative view that denies ADT and ACT while accepting that long exposure to a class of materials may induce changes in phenomenology that lie outside perceptual experience itself.

    Hales, Jason Dean [Idaho National Laboratory; Gamble, Kyle Allan Lawrence [Idaho National Laboratory

    2016-05-01

    The catastrophic events that occurred at the Fukushima-Daiichi nuclear power plant in 2011 have led to widespread interest in research of alternative fuels and claddings that are proposed to be accident tolerant. The United States Department of Energy (DOE) through its Nuclear Energy Advanced Modeling and Simulation (NEAMS) program has funded an Accident Tolerant Fuel (ATF) High Impact Problem (HIP). The ATF HIP is a three-year project to perform research on two accident tolerant concepts. The final outcome of the ATF HIP will be an in-depth report to the DOE Advanced Fuels Campaign (AFC) giving a recommendation on whether either of the two concepts should be included in their lead test assembly scheduled for placement into a commercial reactor in 2022. The two ATF concepts under investigation in the HIP are uranium silicide fuel and iron-chromium-aluminum (FeCrAl) alloy cladding. Utilizing the expertise of three national laboratory participants (Idaho National Laboratory, Los Alamos National Laboratory, and Argonne National Laboratory), a comprehensive multiscale approach to modeling is being used that includes atomistic modeling, molecular dynamics, rate theory, phase-field, and fuel performance simulations. Model development and fuel performance analysis are critical since a full suite of experimental studies will not be complete before AFC must prioritize concepts for focused development. In this paper, we present simulations of the two proposed accident tolerance fuel systems: U3Si2 fuel with Zircaloy-4 cladding, and UO2 fuel with FeCrAl cladding. Sensitivity analyses are completed using Sandia National Laboratories’ Dakota software to determine which input parameters (e.g., fuel specific heat) have the greatest influence on the output metrics of interest (e.g., fuel centerline temperature). We also outline the multiscale modelling approach being employed. Considerable additional work is required prior to preparing the recommendation report for the Advanced

    Vrbanic, I.; Spiler, J.

    2000-01-01

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

    Liquid metal reactor concept looks promising because of its hard neutron spectrum. Sodium reactors benefit a large feedback experience in Japan and in France. Lead reactors have serious assets concerning safety but they require a great effort in technological research to overcome the corrosion issue and they lack a leader country to develop this innovative technology. In molten salt reactor concept, salt is both the nuclear fuel and the coolant fluid. The high exit temperature of the primary salt (700 Celsius degrees) allows a high energy efficiency (44%). Furthermore molten salts have interesting specificities concerning the transmutation of actinides: they are almost insensitive to irradiation damage, some salts can dissolve large quantities of actinides and they are compatible with most reprocessing processes based on pyro-chemistry. Supercritical water reactor concept is based on operating temperature and pressure conditions that infers water to be beyond its critical point. In this range water gets some useful characteristics: - boiling crisis is no more possible because liquid and vapour phase can not coexist, - a high heat transfer coefficient due to the low thermal conductivity of supercritical water, and - a high global energy efficiency due to the high temperature of water. Gas-cooled fast reactors combining hard neutron spectrum and closed fuel cycle open the way to a high valorization of natural uranium while minimizing ultimate radioactive wastes and proliferation risks. Very high temperature gas-cooled reactor concept is developed in the prospect of producing hydrogen from no-fossil fuels in large scale. This use implies a reactor producing helium over 1000 Celsius degrees. (A.C.)

    To report an analysis of the concept of leading change. Nurses have been called to lead change to advance the health of individuals, populations, and systems. Conceptual clarity about leading change in the context of nursing and healthcare systems provides an empirical direction for future research and theory development that can advance the science of leadership studies in nursing. Concept analysis. CINAHL, PubMed, PsycINFO, Psychology and Behavioral Sciences Collection, Health Business Elite and Business Source Premier databases were searched using the terms: leading change, transformation, reform, leadership and change. Literature published in English from 2001 - 2015 in the fields of nursing, medicine, organizational studies, business, education, psychology or sociology were included. Walker and Avant's method was used to identify descriptions, antecedents, consequences and empirical referents of the concept. Model, related and contrary cases were developed. Five defining attributes of leading change were identified: (a) individual and collective leadership; (b) operational support; (c) fostering relationships; (d) organizational learning; and (e) balance. Antecedents were external or internal driving forces and organizational readiness. The consequences of leading change included improved organizational performance and outcomes and new organizational culture and values. A theoretical definition and conceptual model of leading change were developed. Future studies that use and test the model may contribute to the refinement of a middle-range theory to advance nursing leadership research and education. From this, empirically derived interventions that prepare and enable nurses to lead change to advance health may be realized. © 2016 John Wiley & Sons Ltd.

  8. Corporate entrepreneurship - Distilling the concept

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Background: Corporate entrepreneurship (CE is credited for many positive organisational outcomes, including systemic growth and increased revenue. Several terms associated with CE, including strategic renewal, corporate venturing and intrapreneurship are frequently used interchangeably and often confuse scholars, researchers and practitioners. The lack of clarity about the exact meaning of these terms is detrimental to the synergy in the current body of knowledge and the development of models involving these concepts. Objective: The aim of this paper was to describe CE as a unique concept, distinguishable from related concepts. Methodology: Several definitions of CE as well as the related terms were dissected, to identify core elements associated with each of them. The validity of these comprehensive definitions was tested by requesting 68 master’s degree students to classify the definitions. Inter-rater reliabilities were calculated in order to assess the level of agreement in the classification of the constructs. Results: The results indicate that CE is difficult to distinguish from strategic renewal and corporate venturing, but that intrapreneurship seems to be better defined and separate from the other constructs. Conclusion: These results emphasise the conceptual confusion that exists around CE and the need for further clarification of terminology. KEY WORDS Corporate entrepreneurship, strategic renewal, corporate venturing, intrapreneurship.

    Aim To report an analysis of the concept of food insecurity, in order to 1) propose a theoretical model of food insecurity useful to nursing and 2) discuss its implications for nursing practice, nursing research, and health promotion. Background Forty eight million Americans are food insecure. As food insecurity is associated with multiple negative health effects, nursing intervention is warranted. Design Concept Analysis Data sources A literature search was conducted in May 2014 in Scopus and MEDLINE using the exploded term “food insecur*.” No year limit was placed. Government websites and popular media were searched to ensure a full understanding of the concept. Review Methods Iterative analysis, using the Walker and Avant method Results Food insecurity is defined by uncertain ability or inability to procure food, inability to procure enough food, being unable to live a healthy life, and feeling unsatisfied. A proposed theoretical model of food insecurity, adapted from the Socio-Ecological Model, identifies three layers of food insecurity (individual, community, society), with potential for nursing impact at each level. Conclusion Nurses must work to fight food insecurity. There exists a potential for nursing impact that is currently unrealized. Nursing impact can be guided by a new conceptual model, Food Insecurity within the Nursing Paradigm. PMID:25612146

  10. Managerial coaching: a concept analysis.

    Batson, Vicki D; Yoder, Linda H

    2012-07-01

    This article presents a report of a concept analysis of managerial coaching. Managerial coaching has been identified as a means for managers to give support to staff nurses, however, no clear delineation of what behaviours and attributes constitute managerial coaching or differentiate it from other career development relationships is provided in the current nursing literature. The CINAHL, ProQuest, Business Source Complete and PscyhIFNO databases were searched for articles published between 1980-2009 using the keywords coaching, managerial coaching, nurse manager support, nursing leadership, self-efficacy, work environment and empowerment. A hybrid approach was used, incorporating both Walker and Avant's method of concept analysis and King's conceptual system and Theory of Goal Attainment to explore the meaning of managerial coaching. Inclusive years of search ranged from 1980-2009. Managerial coaching is a specific dyadic relationship between the nurse manager and staff nurse intended to improve skills and knowledge as they relate to expected job performance. Antecedents and consequences are categorized at the individual and organizational level. Defining attributes, empirical referents and a model case are presented. The theoretical definition for this concept helps to differentiate it from other types of career development relationships and will give a basis for nurse managers to understand what skills and attributes are necessary to establish an effective managerial coaching relationship with staff nurses. Conceptualization will also assist in developing empirical studies examining managerial coaching behaviours in the work environment. © 2012 Blackwell Publishing Ltd.

  11. Advanced reactor concepts and safety

    1988-06-01

    The need for some consistency in the terms used to describe the evolution of methods for ensuring the safety of nuclear reactors has been identified by the IAEA. This is timely since there appears to be a danger that the precision of many valuable words is being diluted and that a new jargon may appear that will confuse rather than aid the communication of important but possibly diverse philosophies and concepts. Among the difficulties faced by the nuclear industry is promoting and gaining a widespread understanding of the risks actually posed by nuclear reactors. In view of the importance of communication to both the public and to the technical community generally, the starting point for the definition of terms must be with dictionary meanings and common technical usage. The nuclear engineering community should use such words in conformance with the whole technical world. This paper addresses many of the issues suggested in the invitation to meet and also poses some additional issues for consideration. Some examples are the role of the operator in either enhancing or degrading safety and how the meaning or interpretation of the word 'safety' can be expected to change during the next few decades. It is advantageous to use criteria against which technologies and ongoing operating performance can be judged provided that the criteria are generic and not specific to particular reactor concepts. Some thoughts are offered on the need to frame the criteria carefully so that innovative solutions and concepts are fostered, not stifled

    2018-01-01

    To use a concept analysis to determine a clear definition of the term "intentional learning" for use in nursing. The term intentional learning has been used for years in educational, business, and even nursing literature. It has been used to denote processes leading to higher order thinking and the ability to use knowledge in new situations; both of which are important skills to develop in nursing students. But the lack of a common, accepted definition of the term makes it difficult for nurse educators to base instruction and learning experiences on or to evaluate its overall effectiveness in educating students for diverse, fast-paced clinical practices. A concept analysis following the eight-step method developed by Walker and Avant (2011). Empirical and descriptive literature.  Five defining attributes were identified: (1) self-efficacy for learning, (2) active, effortful, and engaged learning, (3) mastery of goals where learning is the goal, (4) self-directed learning, and (5) self-regulation of learning. Through this concept analysis, nursing will have a clear definition of intentional learning. This will enable nurse educators to generate, evaluate, and test learning experiences that promote further development of intentional learning in nursing students. Nurses in practice will also be able to evaluate if the stated benefits are demonstrated and how this impacts patient care and outcomes. © 2017 Wiley Periodicals, Inc.

  13. Concept of Lunar Energy Park

    Niino, Masayuki; Kisara, Katsuto; Chen, Lidong

    1993-10-01

    This paper presents a new concept of energy supply system named Lunar Energy Park (LEP) as one of the next-generation clean energy sources. In this concept, electricity is generated by nuclear power plants built on the moon and then transmitted to receiving stations on the earth by laser beam through transporting systems situated in geostationary orbit. The lunar nuclear power plants use a high-efficiency composite energy conversion system consisting of thermionic and thermoelectric generators to change nuclear thermal energy into electricity directly. The nuclear resources are considered to be available from the moon, and nuclear fuel transport from earth to moon is not necessary. Because direct energy conversion systems are employed, the lunar nuclear plants can be operated and controlled by robots and are maintenance-free, and so will cause no pollution to humans. The key technologies for LEP include improvements of conversion efficiency of both thermionic and thermoelectric converters, and developments of laser-beam power transmission technology as well. The details, including the construction of lunar nuclear plants, energy conversion and energy transmission systems, as well as the research plan strategies for this concept are reviewed.

    1989-01-01

    In Canada the need for advanced neutron sources has long been recognized. During the past several years Atomic Energy of Canada Limited (AECL) has been developing the new MAPLE multipurpose reactor concept. To date, the MAPLE program has focused on the development of a modest-cost multipurpose medium-flux neutron source to meet contemporary requirements for applied and basic research using neutron beams, for small-scale materials testing and analysis and for radioisotope production. The basic MAPLE concept incorporates a compact light-water cooled and moderated core within a heavy water primary reflector to generate strong neutron flux levels in a variety of irradiation facilities. In view of renewed Canadian interest in a high-flux neutron source, the MAPLE group has begun to explore advanced concepts based on AECL's experience with heavy water reactors. The overall objective is to define a high-flux facility that will support materials testing for advanced power reactors, new developments in extracted neutron-beam applications, and/or production of radioisotopes. The design target is to attain performance levels of HFR-Grenoble, HFBR, HFIR in a new heavy water-cooled, -moderated,-reflected reactor based on rodded LEU fuel. Physics, shielding, and thermohydraulic studies have been performed for the MAPLE heavy water reactor. 14 refs., 4 figs., 1 tab

    2017-07-01

    Harnessing community assets may help public health nurses address health inequalities. Cultural factor is one such asset, which is assumed to be capital in a community. Cultural capital is a key concept for understanding the causes of public health issues. This paper provided an in-depth analysis of "cultural capital" as a concept. Rodgers' evolutionary methodology was used for concept analysis. Forty-two studies published in English between 1998 and 2015 were retrieved from MEDLINE by searching for "cultural capital" in the title field. Antecedents of cultural capital included "educational environment," "belongingness in one's social group," "existing health/social inequalities," and "daily behavior." Cultural capital's identified attributes were "social cultivation," "reproductive rubric," "practical knowledge," and "autogenic ability." Cultural capital's consequences were "improving productivity," "reducing health/social inequality," and "enhancing well-being." Cultural capital is defined as capital characterized by cultivation, rubric, knowledge, and ability. These aspects of cultural capital are typically autogenic, and accumulate and reproduce through lifelong community membership. Cultural capital reduces inequality and ultimately enhances the well-being of individuals and the community through bonding, bridging, and linking economic and social capital. © 2017 Wiley Periodicals, Inc.

    2017-10-01

    Worsening quality indicators of health care shake public trust. Although safety and quality of care in hospitals can be improved, healthcare quality remains conceptually and operationally vague. Therefore, the aim of this analysis is to clarify the concept of healthcare quality. Walker and Avant's method of concept analysis, the most commonly used in nursing literature, provided the framework. We searched general and medical dictionaries, public domain websites, and 5 academic literature databases. Search terms included health care and quality, as well as healthcare and quality. Peer-reviewed articles and government publications published in English from 2004 to 2016 were included. Exclusion criteria were related concepts, discussions about the need for quality care, gray literature, and conference proceedings. Similar attributes were grouped into themes during analysis. Forty-two relevant articles were analyzed after excluding duplicates and those that did not meet eligibility. Following thematic analysis, 4 defining attributes were identified: (1) effective, (2) safe, (3) culture of excellence, and (4) desired outcomes. Based on these attributes, the definition of healthcare quality is the assessment and provision of effective and safe care, reflected in a culture of excellence, resulting in the attainment of optimal or desired health. This analysis proposes a conceptualization of healthcare quality that defines its implied foundational components and has potential to improve the provision of quality care. Theoretical and practice implications presented promote a fuller, more consistent understanding of the components that are necessary to improve the provision of healthcare and steady public trust. © 2017 Wiley Periodicals, Inc.

    Fifteen-day pregnant Wistar/Furth rats were irradiated with 100 rads of x ray of fast neutron (14.1 MeV). Fast neutron was found to be more effective than x rays in reducing the number of live-births and in retarding the postnatal growth of the offspring. Among the various organs examined, the brain, uterus, spleen and gonads were highly radiosensitive in terms of organ weight. Microscopic examination revealed a marked dysplasia of the ovary in the fast neutron-irradiated rats. Pre-conception irradiation did not cause any deleterious effects on the offspring. No substantial difference was noted in the peripheral blood pictures or on the tumor incidence in rats born from the irradiated female rats. On the other hand, it was noteworthy that N-butylnitrosourea given transplacentally induced 3 cases of brain tumor. The incidence of leukemia and mammary tumor was significantly higher in the irradiated or carcinogen-treated pregnant rats.

  19. Laughing rats are optimistic.

    Rafal Rygula

    Full Text Available Emotions can bias human decisions- for example depressed or anxious people tend to make pessimistic judgements while those in positive affective states are often more optimistic. Several studies have reported that affect contingent judgement biases can also be produced in animals. The animals, however, cannot self-report; therefore, the valence of their emotions, to date, could only be assumed. Here we present the results of an experiment where the affect-contingent judgement bias has been produced by objectively measured positive emotions. We trained rats in operant Skinner boxes to press one lever in response to one tone to receive a food reward and to press another lever in response to a different tone to avoid punishment by electric foot shock. After attaining a stable level of discrimination performance, the animals were subjected to either handling or playful, experimenter-administered manual stimulation - tickling. This procedure has been confirmed to induce a positive affective state in rats, and the 50-kHz ultrasonic vocalisations (rat laughter emitted by animals in response to tickling have been postulated to index positive emotions akin to human joy. During the tickling and handling sessions, the numbers of emitted high-frequency 50-kHz calls were scored. Immediately after tickling or handling, the animals were tested for their responses to a tone of intermediate frequency, and the pattern of their responses to this ambiguous cue was taken as an indicator of the animals' optimism. Our findings indicate that tickling induced positive emotions which are directly indexed in rats by laughter, can make animals more optimistic. We demonstrate for the first time a link between the directly measured positive affective state and decision making under uncertainty in an animal model. We also introduce innovative tandem-approach for studying emotional-cognitive interplay in animals, which may be of great value for understanding the emotional

    The Center for Microbial Oceanography: Research and Education (C-MORE) is a multi-institution Science and Technology Center, established by the National Science Foundation in 2006. C-MORE's research mission is to facilitate a more comprehensive understanding of the diverse assemblages of microorganisms in the sea, ranging from the genetic basis of marine microbial biogeochemistry including the metabolic regulation and environmental controls of gene expression, to the processes that underpin the fluxes of carbon, related bioelements, and energy in the marine environment. The C-MORE education and outreach program is focused on increasing scientific literacy in microbial oceanography among students, educators, and the general public. A first step toward this goal is defining the key concepts that constitute microbial oceanography. After lengthy discussions with scientists and educators, both within and outside C-MORE, we have arrived at six key concepts: 1) Marine microbes are very small and have been around for a long time; 2) Life on Earth could not exist without microbes; 3) Most marine microbes are beneficial; 4) Microbes are everywhere: they are extremely abundant and diverse; 5) Microbes significantly impact our global climate; and 6) There are new discoveries every day in the field of microbial oceanography. A C-MORE-produced brochure on these six key concepts will be distributed at the meeting. Advanced copies may be requested by email or downloaded from the C-MORE web site(http://cmore.soest.hawaii.edu/downloads/MO_key_concepts_hi-res.pdf). This brochure also includes information on career pathways in microbial oceanography, with the aim of broadening participation in the field. C-MORE is eager to work in partnership to incorporate these key concepts into other science literacy publications, particularly those involving ocean and climate literacy.

    Full Text Available This article presents a review of the existing networks andthe NGN concept. By analysing the condition of the existingtelecommunication networks and services it is obvious that theyare different single-se1vice networks that cannot meet the requirementsof the users for various se1vices. The increased demandsof the users for telecommunication se1vices have inducedthe introduction of liberalization in the telecommunicationmarket. That opened the door for competition and greatinvestments in the development of telecommunication networks.The existing telecommunication networks orientated to thetransmission of voice and the existing data network could notbe adapted to new requirements without difficulties. That is thereason why the search for a solution for convergence and unionof a great number of different single-service networks started.The basic requirement was reduced in the end to the conceptionof the universal wideband data network that can meet all thedemands of the users by dividing the resources. As a collSequenceof that it was necessmy to find the solution for the transmissionof voice by a data network. The solution was seen in theerection of softswitch architecture for VoiP. Thus, the voicewould be transmitted by packets as one of the components indata transmission. It was necessary to define protocols for enablingthe operation in the NGN conception, as well as to thoroughlyobserve the problems of the JP telephony operation in regardto the real-time voice component. Apart from these tasks itwas necessmy to see how to adapt the existing networks into theNGN conception and to provide interaction between differentnetworks and different layers of networks by applying certainstandards and protocols. The awareness of the necessity ofgradual introduction and realization of NGN conception hasbecome obvious, always in the relation to the existing conditionof PSTN and the users' demands.

    2017-12-01

    Full Text Available In early 21st century, the question “Is Turkey becoming secularized contrary to popular belief?” was one of the discussions occupying Turkish public opinion. These discussions led to the encounter of two different concepts of secularization, “theological (Islamic” and "metaphysical", and to put forward different claims using the same concept. Hence, it became evidentwas understood that a discussion was necessary to understand what secularization is and what it is not before starting any debate on Turkey's secularization. That is because the metaphysical discussion that defines secularization as the decline in the social influence of metaphysical realm (religion, religion-like mechanisms, folk religions, superstitious beliefs, etc. is overshadowed by the Islamic definition describing secularization as "irreligiousness" or "non-Islamism". Therefore, discussingTo understand the social transformation in Turkey, this article attempts to explain that metaphysical rather than theological definition of secularization is necessary for understanding the social implications of the process of modernization.

    Highlights: • ENEA designed, developed and tested a laser based In Vessel Viewing System (IVVS). • IVVS mechanical design has been revised from 2011 to 2013 to meet ITER requirements. • Main improvements are piezoceramic actuators and a step focus system. • Successful qualification activities validated the concept design for ITER environment. - Abstract: ENEA has been deeply involved in the design, development and testing of a laser based In Vessel Viewing System (IVVS) required for the inspection of ITER plasma-facing components. The IVVS probe shall be deployed into the vacuum vessel, providing high resolution images and metrology measurements to detect damages and possible erosion. ENEA already designed and manufactured an IVVS probe prototype based on a rad-hard concept and driven by commercial micro-step motors, which demonstrated satisfying viewing and metrology performances at room conditions. The probe sends a laser beam through a reflective rotating prism. By rotating the axes of the prism, the probe can scan all the environment points except those present in a shadow cone and the backscattered light signal is then processed to measure the intensity level (viewing) and the distance from the probe (metrology). During the last years, in order to meet all the ITER environmental conditions, such as high vacuum, gamma radiation lifetime dose up to 5 MGy, cumulative neutron fluence of about 2.3 × 10{sup 17} n/cm{sup 2}, temperature of 120 °C and magnetic field of 8 T, the probe mechanical design was significantly revised introducing a new actuating system based on piezo-ceramic actuators and improved with a new step focus system. The optical and mechanical schemes have been then modified and refined to meet also the geometrical constraints. The paper describes the mechanical concept design solutions adopted in order to fulfill IVVS probe functional performance requirements considering ITER working environment and geometrical constraints.

  5. Analysis of digester design concepts

    1979-01-29

    Engineering economic analyses were performed on various digester design concepts to determine the relative performance for various biomass feedstocks. A comprehensive literature survey describing the state-of-the-art of the various digestion designs is included. The digester designs included in the analyses are CSTR, plug flow, batch, CSTR in series, multi-stage digestion and biomethanation. Other process options investigated included pretreatment processes such as shredding, degritting, and chemical pretreatment, and post-digestion processes, such as dewatering and gas purification. The biomass sources considered include feedlot manure, rice straw, and bagasse. The results of the analysis indicate that the most economical (on a unit gas cost basis) digester design concept is the plug flow reactor. This conclusion results from this system providing a high gas production rate combined with a low capital hole-in-the-ground digester design concept. The costs determined in this analysis do not include any credits or penalties for feedstock or by-products, but present the costs only for conversion of biomass to methane. The batch land-fill type digester design was shown to have a unit gas cost comparable to that for a conventional stirred tank digester, with the potential of reducing the cost if a land-fill site were available for a lower cost per unit volume. The use of chemical pretreatment resulted in a higher unit gas cost, primarily due to the cost of pretreatment chemical. A sensitivity analysis indicated that the use of chemical pretreatment could improve the economics provided a process could be developed which utilized either less pretreatment chemical or a less costly chemical. The use of other process options resulted in higher unit gas costs. These options should only be used when necessary for proper process performance, or to result in production of a valuable by-product.

  6. The SAFR liquid metal concept

    Baumeister, E.B.

    1987-01-01

    The Sodium Advanced Fast Reactor (SAFR) modular reactor concept is being developed by the team of Rockwell International, Combustion Engineering, and Bechtel under the U.S. Department of Energy's (DOE's) Advanced Liquid Metal Reactor (LMR) program. The SAFR plant would provide a viable alternate to light water reactors, especially for applications favoring small incremental capacity additions. SAFR is also a logical step to facilitate the later transition to LMFBRs. The SAFR plant concept employs multiple 350-MWe LMR Power Pak modules. Each Power Pak is a standardized, shop-fabricated unit that can be barge-shipped to the plant site for installation. The 350-MWe size allows SAFR to capitalize on all the inherent safety features provided by small reactors and factory fabrication, while still preserving some economy of scale. Shop fabrication minimizes nuclear-grade field fabrication and minimizes the overall plant construction schedule and capital cost. Each Power Pak consists of one reactor assembly and associated heat transfer equipment coupled to a single turbine generator. The reactor core employs mixed uranium-plutonium zirconium alloy metal fuel. The metal-alloy fuel (which has been used in EBR-II) has cost, safety, and safeguard advantages. The intrinsic properties of the sodium coolant (e.g., high boiling point, low vapor pressure, and strong natural convection), blended together with the pool-type LMR concept and the metal fuel, result in an inherently safe plant. Passive inherent features provide both public safety and plant investment protection. Refueling is carried out annually on each Power Pak, replacing one-fourth of the core over a 6-day refueling outage. A colocated pyroprocessing fuel cycle facility can be accommodated at the site such that no off-site shipments are required. (J.P.N.)

    Crohn's disease (CD) is a chronic inflammatory disorder characterized by periods of clinical remission alternating with periods of relapse defined by recurrent clinical symptoms. Persistent inflammation is believed to lead to progressive bowel damage over time, which manifests with the development of strictures, fistulae and abscesses. These disease complications frequently lead to a need for surgical resection, which in turn leads to disability. So CD can be characterized as a chronic, progressive, destructive and disabling disease. In rheumatoid arthritis, treatment paradigms have evolved beyond partial symptom control alone toward the induction and maintenance of sustained biological remission, also known as a 'treat to target' strategy, with the goal of improving long-term disease outcomes. In CD, there is currently no accepted, well-defined, comprehensive treatment goal that entails the treatment of both clinical symptoms and biologic inflammation. It is important that such a treatment concept begins to evolve for CD. A treatment strategy that delays or halts the progression of CD to increasing damage and disability is a priority. As a starting point, a working definition of sustained deep remission (that includes long-term biological remission and symptom control) with defined patient outcomes (including no disease progression) has been proposed. The concept of sustained deep remission represents a goal for CD management that may still evolve. It is not clear if the concept also applies to ulcerative colitis. Clinical trials are needed to evaluate whether treatment algorithms that tailor therapy to achieve deep remission in patients with CD can prevent disease progression and disability.

    Sequential and parallel computer programs are contrasted, and the problems of implementing compilers are stated, with special reference to the Pascal language. Process and monitor data types in computer programming are described, various procedures are listed and the monitor concept is applied to a generator-user problem. A Pascal initiator program is listed. It is claimed that the monitor approach can yield lower fault levels than assembler or semaphore approaches. It is pointed out that monitors for program synchronisation are only applicable for common, and not for distributed, storage systems. 9 references.

  12. Trust as a Critical Concept

    In this articlei I will argue that trust is a fundamental and critical concept because trust is the direct or transcendental constitutive ground of most social phenomena, as well as applicable as an operational method in critical theory. There are two different but overlapping positions on trust I...... address in this article. One is the standpoint we find in business strategy, that trust is naïve to show, and control or contracts are presumed better. In the strategy game the idealistic good guys seems to lose (Arrow 1974), (Williamson 1975). The other position is the position taken by systems theory...

    After a philosophical introduction on control theory and its position among various branches of science, mathematical control theory and its connection with functional analysis are discussed. A chapter on system theory concepts follows. After a summary of results and notations in the general theory of ordinary differential equations, a qualitative theory of control dynamical systems and chapters on the topological dynamics, and the controllability of linear systems are presented. As examples of autonomous linear systems, the switching locus for the synthesis of optimal controllers and linear dynamics with quadratic cost optimization are considered. (author)

    During the past several years, Atomic Energy of Canada Limited (AECL) has been developing the new MAPLE multipurpose reactor concept, which is capable of generating peak thermal neutron fluxes of up to 3 x 10 18 n/m 2 s in its heavy water reflector at a nominal thermal power level of 15MW. An assessment of the MAPLE-D 2 O reactor has shown that it could also be used as a high-flux neutron source. it could be developed to be used for several applications if a 12-site annular core is used. Thermal fluxes several times greater than in existing facilities would be available (author)

    The importance of accounting for nuclear materials to the efficient, safe, and economical operation of nuclear facilities is introduced, and the following topics are covered: material balance equation; item control areas; material balance uncertainty; decision procedures for materials accounting; conventional and near-real-time accounting; regulatory requirements of the US Department of Energy and the Nuclear Regulatory Commission; and a summary related to the development of a materials accounting system to implement the basic concepts described. The summary includes a section on each of the following: problem definition, system objectives, and system design

  16. [Mental Health: Concepts, Measures, Determinants].

    Objectives This article aims to situate the concept of mental health in a historical perspective. This article presents the most commonly used measurement tools in Canada and elsewhere in the world to assess specific and multiple dimensions of mental health; when available, psychometric properties are discussed. Finally, research findings on quality of life and mental health determinants are presented.Methods A literature review of concepts, measurement and determinants of mental health is presented in this paper. The selection of measurement scales presented is based on the findings of the research reports conducted by the second author, an expert on mental health measures, for Health Canada and Statistics Canada.Results Mental health is more than the absence of mental illness; rather it is a state of complete well-being, which refers to our ability to enjoy life and deal with the challenges we face. Accordingly, mental health and mental illness are not extremes of the same continuum, but distinct yet correlated concepts. The traditional conceptualization suggesting that mental health represents simply the absence of mental illness has been replaced, in the last few decades, by a more holistic characterization, which directly concerns public health. The components of mental health include emotional well-being/quality of life (QOL) and psychological and social well-being. Mental health influences the personal and social functioning of individuals, justifying the importance of intervening upstream to promote mental health. Specific scales are relevant for obtaining a detailed measure of one aspect of well-being in particular (emotional/quality of life, psychological or social well-being); however, to account for the global mental health status, measurement tools that integrate all three forms of well-being (emotional, psychological and social) should be privileged. A diversity of determinants at the individual, social and neighbourhood levels influence quality of

    and activities around key social pedagogical concepts, such as the Common Third, the 3 P’s, the Zone of Proximal Development and the Learning Zone model. In the article we explore how a joint activity, for example playing soccer, can be seen as a pedagogical activity and with what intentions it is undertaken......“Now I can actually play soccer with the young people without fearing that my colleagues think I am escaping the paper work.” These were the words from a participant in a social pedagogy training course in England a few years ago. This understanding emerged through in-depth discussions...

  18. Methylmercury chloride induces learning deficits in prenatally treated rats

    Methylmercury chloride (MMC) was given to pregnant rats on the 6th, 7th, 8th, and 9th day after conception in doses of 0.05 and 2.0 mg/kg/day. The female offspring of these animals were tested 90 days after birth for learning ability using operant conditioning procedures. The rats were kept at 90% of their normal body weight and trained in a lever-box to press a bar in order to obtain a food pellet. Significant differences in the acquisition speed became apparent when the ratio of bar presses to reward was increased in a classical contingency of differential reinforcement of high rates even at MMC-doses of 4 x 0.05 mg/kg. These differences were not found in the general motility level nor in motor coordination.

    The purpose of this paper is to describe two learning activities undertaken by lecturers, so that students can understand a mathematical concept. The mathematical concept studied in this research is the Vector Space in Linear Algebra instruction. Classroom Action Research used as a research method with pre-service mathematics teacher at University of Papua as the research subject. Student participants are divided into two parallel classes, 24 students in regular class, and remedial class consist of 18 students. Both approaches, construct and reconstruction concept, are implemented on both classes. The result shows that concept construction can only be done in regular class while in remedial class, learning with concept construction approach is not able to increase students' understanding on the concept taught. Understanding the concept of a student in a remedial class can only be carried out using the concept reconstruction approach.
