    Full Text Available Cette étude concerne un acier faiblement allié au manganèse et chrome. L’utilisation principale de cet acier est la fabrication des tubes sans soudure, employés pour le forage ou le transport pétrolier. Les tubes traités thermiquement doivent supporter d’importantes contraintes de tension et de compression, sans risque de rupture. Les tubes trempés à l’eau souffrent d’une hétérogénéité structurale impliquant une diminution de dureté à la surface interne. Le but de cette étude est de déterminer les structures de l’acier après différents types de traitements, au cours de refroidissement continus dans les conditions industrielles de trempe (930°C et de revenu (670°C. Les résultats montrent que la vitesse critique de trempe est de 50°C/sec et, pour éviter la formation de la ferrite, une vitesse plus grande que 12°C/sec est nécessaire. Cet acier a une bonne trempabilité (11mm. La décroissance de la dureté de la martensite revenue est remarquable lorsque la température atteint 600°C.

    Selection tests were carried out on commercial steels from the viewpoint of their resistance to oxidation in carbon dioxide, under 25 atmospheres pressure, between 350 and 600 deg. C. Comparative curve of oxidation kinetics were obtained, from which the influence of various additive elements can be found; small amounts of aluminium particularly seem to be favourable in the case of only slightly alloyed steels.

    Low-Si alloyed steels, with Si content ranging from 0.25 to 3.2 wt%, as potential candidate materials for high-level nuclear waste disposal containers, have been studied four the point of view of their corrosion behaviour at 90 deg C in an aqueous solution simulating groundwater (0.1 M NaCl borate-buffered solution with a pH of 8.5) both in reducing and in aerated conditions. The influence of silicate addition to the solution is examined so as to represent the silicon of groundwater, coming from the clay dissolution. When no silicate was added to the solution, silicon as an alloying element was proved to degrade in the first moments the steel ability to passivate. For longer immersion times, protective effects developed most efficiently on the steel containing 3.2 wt% silicon both in reducing an in aerating conditions, Infrared spectroscopy, EDSX, XRD and Raman microprobe were applied to characterise the oxide layer composition, which was found to be a mixture of magnetite and maghemite. In the presence of silicate in the solution, clay-like iron silicates appeared in the corrosion layer. Electrochemical tests results show that adding silicate into solution resulted in increasing the steel ability to passivate. In the short term, the inhibiting effect of silicate was confirmed by mass loss tests, but the tendency was inverse in the long term. Silicate iron layers were eventually less protective than the magnetite layers formed in the absence of silicate. (author)

    The fracture mechanism in a low alloy steel, used in the pressurised water reactor vessel, has been studied in the ductile to brittle transition temperature range. We used the local approach of fracture in conjunction with both fractographic observations and numerical simulations. Previous studies suggested the onset of cleavage to be favoured by the presence of nearby manganese sulphide (MnS) clusters: the ductile damaged zone localised inside a cluster increases the stress around it, and so contribute to the triggering of cleavage due to nearby classical sites, like carbides. The experimental study of size dependence and anisotropy on the global fracture behaviour, together with fractographic observations, give here the proof of the influence of MnS clusters on the onset of cleavage in this steel. Fracture behaviour of pre-cracked specimens tested in the transition regime has then been simulated, by three dimensional finite element method computations. Ductile tearing process preceding the cleavage onset at those temperatures regime was well reproduced by the Rousselier's model. Failure probabilities, related to given stress states, has been given by post-processor calculations, using a probabilistic model based on the specific cleavage fracture process. Fracture toughness scatter of the steel, tested in the transition regime, is then well reproduced by those calculations. However, the critical cleavage stress of an elementary volume, that scales for the fracture process, is still assumed to be temperature dependant. Numerical simulations of the local fracture process suggest that this temperature effect can partly be explained by the temperature dependant decrease of the stress amplification due to the MnS clusters.

    Behaviour of low-alloyed steels heated in CO{sub 2} medium under pressure is reported. Tests are carried out in the range of erature reached in the CO{sub 2} cooled reactors (vessel, thermal shield, pipes). The observed weight increases are small, even after more than a thousand hours of heating at 350 deg. C, but oxidation curve looks like progressing linearly. Furthermore, the oxide formed under a pressure of 15 kg/cm{sup 2} is undoubtedly more compact and adherent than the one formed under a pressure of 1 kg/cm{sup 2}. Finally, for practical use, CO{sub 2} steel pipes surface has to be sand blast and pickled. A following phosphatizing protects it from atmospheric corrosion during assembling, but these treatments have no influence on the behaviour of these steels heated in CO{sub 2}. (author)Fren.

  8. Intergranular brittle fracture of a low alloy steel induced by grain boundary segregation of impurities: influence of the microstructure; Rupture intergranulaire fragile d'un acier faiblement allie induite par la segregation d'impuretes aux joints de grains: influence de la microstructure

    The study contributes to improve the comprehension of intergranular embrittlement induced by the phosphorus segregation along prior austenitic grain boundaries of low alloy steels used in pressurized power reactor vessel. A part of this study was performed using a A533 steel which contains chemical fluctuations (ghost lines) with two intensities. Axi-symmetrically notched specimens were tested and intergranular brittle de-cohesions were observed in the ghost lines. The fracture initiation sites observed on fracture surfaces were identified as MnS inclusions. A bimodal statistic obtained in a probabilistic model of the fracture is explained by the double population of ghost lines' intensities. A metallurgical study was performed on the same class of steel by studying the influence of the microstructure on the susceptibility to temper embrittlement. Brittle fracture properties of such microstructures obtained by dilatometric experiments were tested on sub-sized specimens to measure the V-notched fracture toughness. Fraction areas of brittle fracture modes were determined on surface fractures. A transition of the fracture mode with the microstructure is observed. It is shown that tempered microstructures of martensite and lower bainite are more susceptible to intergranular embrittlement than tempered upper bainitic microstructure. The intergranular fracture is the most brittle mode. The analysis of crystalline mis-orientations shows a grain boundary structure appreciably more coherent for tempered microstructures of martensite and lower bainite. The higher density of randomgrain boundaries is susceptible to drag the phosphorus in the upper bainitic matrix and to make the quantity of free phosphorus decreasing. Microstructure observations show a difference in the size and the spatial distribution of carbides, essentially cementite, between tempered martensite and upper bainite. It can explain the bigger susceptibility of this last microstructure to cleavage mode. (author)

    It is indispensable to guarantee the integrity of PWR reactor vessels during an accidental running: in this context, the understanding and the modelling of the mechanisms of brittle rupture of steels are decisive elements of the complicated estimation of the service life of reactor vessels. The models of local approach of rupture by cleavage are one of the main tools of anticipation of the tensile strength of low alloy steels. In this work, the effect of the stresses heterogeneities in a local criteria of initiation of cleavage has been taken into account. The results of the microstructure calculations are used for proposing a statistical description of the local stresses distribution evolution. This statistical approach allows to propose a local approach model of the rupture depending both of the mechanical heterogeneities and of the sizes distributions of the defects. The behaviour of the material and its evolution are characterized at the microscopic and macroscopic scales in the temperature range [25 C, -196 C]. Simple tensile tests, velocity and temperature rises tests and toughness tests have been carried out. A micro-mechanical behaviour model describing the plastic behaviour below the transition temperature T{sub a} has been proposed. The behaviour law is based on the deformation mechanisms described in bibliography and identified by an inverse method from mechanical tests. The TEM observations and the characterization of the behaviour thermally activated allow to determine several parameters of the model. Simulations are carried out in order to model the main stress distributions {sigma}{sub 1} in two bainite microstructures corresponding to the elementary volume of the local approach of the rupture. The temperature and the triaxiality effects on the evolutions of the heterogeneities is characterized. A distribution function describing the distribution of the local values of {sigma}{sub 1} in terms of the main and equivalent mean stresses {sigma}{sub 1} and {sigma}{sub m} in the microstructure is proposed. This function is used for formulating a model of rupture local approach integrating the distribution of the critical defects sizes and the distributions of {sigma}{sub 1}. It is shown that in some cases, the dispersion of the local stresses is sufficient to explain the dispersions of the rupture stresses at the scale of the elementary volume. The dispersions of the rupture stresses are in agreement with those given by the Beremin model. The taken into account of the mechanical heterogeneities allows to introduce a dependency of the rupture probability in terms of temperature, of deformation and of triaxiality. (O.M.)

    Casemix has given allied health professionals the opportunity to review their approaches to patient care, contribute to reducing inpatient costs and improve quality of care. The National Allied Health Casemix Committee was formed in 1993 to advance allied health participation in casemix. The Committee has taken the first step in establishing cost weights for allied health through the Australian Allied Health Activity Classification, which defines allied health inputs in terms of clinical care, clinical service management, teaching and training, and research. Work is being done on generic classification of allied health inputs, and studies are examining what allied health activities are accounted for by DRGs and ICD-9-CM. Allied health has taken up the challenge of casemix, but better access to information technology will enhance its continued contribution.

    Because of the excellent corrosion resistance of stainless steels and the interest in gadolinium as a poison material, alloys of the two compounds were studied.Gadolinium was alloyed with AISE 304-type and chromium-type stainless steels; and then phase relationships, fabricability and properties were studied. The melting points of minor phases in alloys containing low percentages of gadolinium were noted to have a large effect on the structures resulting from equilibrating treatments and fabricability of the steels. When gadolinium was alloyed with the chromium-nickel-type steel, two minor phases, Fe{sub 9}Gd and Ni{sub 7}Gd, were observed to melt at 1080 Degree-Sign C, which limited the heat treatment and fabrication temperatures. Alloys with up to 5 wt.% gadolinium were successfully fabricated, and mechanical and corrosion properties were determined. No changes in the mechanical properties or resistance to hot-water corrosion of the steel were observed on alloying with up to about 3 wt.% gadolinium. Because of fabrication temperature limitations placed on chromium-nickel steels by the melting point of the minor phases, the effects of gadolinium on chromium steels were studied. Only one minor phase that melted at 1320 Degree-Sign C was noted on investigation of the 10 wt. % gadolinium isopleth in the chromium-iron-gadolinium alloy system. This property would enable one to equilibrate and fabricate these gadolinium steels at normally used temperatures.

    Multinational companies are the driving force behind globalization, but they are also the source of many of its most painful consequences, including currency crises, cross-border pollution, and overfishing. These problems remain unsolved because they are beyond the scope of individual governments; transnational organizations have also proved unequal to the task. Nonprofit, nongovernmental organizations have leaped into the breach. To force policy changes, they have seized on all forms of modern persuasion to influence public sentiment toward global traders, manufacturers, and investors. By partnering with NGOs instead of opposing them, companies can avoid costly conflict and can use NGOs' assets to gain competitive advantage. So far, however, most companies have proved ill equipped to deal with NGOs. Large companies know how to compete on the basis of product attributes and price. But NGO attacks focus on production methods and their spillover effects, which are often noneconomic. Similarly, NGOs are able to convert companies' standard competitive strengths--such as size and wide market awareness of their brands--into liabilities. That's because the wealthier and better known a company is, the juicier the target it makes. Emboldened by their successes, NGOs continue to take on new causes. By partnering with NGOs instead of reflexively opposing them, companies could draw on NGOs' key strengths--legitimacy, awareness of social forces, distinct networks, and specialized technical expertise--which most companies could use more of. And with NGOs as allies and guides, companies should also be able to accelerate innovation, foresee shifts in demand, shape legislation affecting them, and, in effect, set technical and regulatory standards for their industries.

    Nuclear centres often have to solve problems raised by the elimination of large volumes of slightly radioactive liquid effluent. As things stand at present, the method usually adopted consists in expelling this effluent into the main water system in order to dilute it to a maximum, and thus to lower its radioactive isotope concentration to below the norms imposed by the Public Health Service. This technique requires systematic checking of the water system and its dependences, and demands a thorough knowledge of adsorption and fixation processes.

    Various techniques for studying corrosion by molten sodium have been developed and applied to the case of 18/10 austenitic steels. The results obtained are discussed as a function of various parameters: type of steel, temperature, oxygen content of the sodium, surface treatment, welds, mechanical strain. In general, these steels have an excellent resistance to sodium when the oxygen content is limited by a simple purification system of the 'cold trap' type, and when an attempt is made to avoid cavitation phenomena which are particularly dangerous, as is shown by the example given. (authors) [French] Des techniques d'etude de la corrosion par le sodium fondu en circulation ont ete mises au point et appliquees au cas des aciers austenitiques 18/10. Les resultats obtenus sont discutes en fonction de differents parametres: nuance de l'acier, temperature, teneur en oxygene du sodium, traitement de surface, soudure, contrainte mecanique. D'une maniere generale, ces aciers ont une excellente tenue dans le sodium lorsque, sa teneur en oxygene est limitee par un systeme simple de purification du type ''piege froid'' et lorsque l'on fait en sorte d'eviter les phenomenes de cavitation particulierement dangereux, comme il ressort d'un exemple cite.

This research examines whether the self-confidence and stereotype (dis-confirming behavior of targets of sexism can be bolstered when other male versus female sources suggest that sexism may have played a role. Both Study 1 (N = 78 and Study 2 (N = 90 show that a suggestion of sexism has more beneficial effects when it is made by male sources than when it is made by female sources. When males suggested that sexism had taken place, targets reported more self-confidence (less self-handicapping and higher personal performance state self-esteem and showed less stereotype confirmation (less self-stereotyping and better task performance than when sexism was suggested by a female source. Study 2 additionally revealed that targets are more likely to file a complaint when men suggest that sexism took place than when this same suggestion was made by women. These results indicate that men can constitute important allies against sexism if they speak out when sexist treatment takes place.

    A theoretical framework and practical suggestions for incorporating games and simulation into allied health instruction are presented. Research findings that support the use of educational simulation/games as a tool for higher cognitive learning are discussed. Examples and step-by-step instructions are given to help allied health educatiors and students write their own simulation games, try them out, evaluate them, and incorporate them into classroom use to stimulate interaction. Advantages of using educational simulation/games in allied health education as well as possible disadvantages of this teaching strategy are discussed. Use of instructional games to enhance teaching effectiveness as measured by student achievement in the allied health fields is emphasized.

    The aim of this study was to explore self-reported transformational leadership behavior profiles within the six largest allied health profession groups in the National Health Service in Scotland and to determine whether factors such as seniority of grade, locus of employment, and/or leadership training have a positive influence on transformational leadership behaviors. A postal survey comprising the shorter version of the Multifactorial Leadership Questionnaire (MLQ) and contextual demographic information was completed by 753 allied health professionals from four Health Board areas across Scotland who were randomly selected through a modified cluster sampling technique. The MLQ contains 36 items that measure nine identified leadership factors; however, only the responses to the five transformational leadership factors are reported here. The study identified significant differences in transformational leadership behaviors between individual allied health professions. Radiographers and podiatrists scored consistently lower than the other professional groups across the range of transformational behaviors. Seniority of grade significantly influenced the scores, with higher-graded staff reporting greater leadership behaviors (p leadership training also positively influenced transformational behaviors (p transformational leadership behaviors between individual allied health professions, indicating that some professional groups are inherently advantaged in embracing the modernization agenda. This highlights an as-yet missed opportunity for effectively targeting and evaluating multidisciplinary leadership training programs across the allied health professions.

    Allied health professionals are vital for effective healthcare yet there are continuing shortages of these employees. Building on work with other healthcare professionals, the purpose of this paper is to investigate the influence of psychological contract (PC) breach and types of organisational justice on variables important to retention among allied health professionals: mental health and organisational commitment. The potential effects of justice on the negative outcomes of breach were examined. Multiple regressions analysed data from 113 allied health professionals working in a medium-large Australian healthcare organisation. The main negative impacts on respondents' mental health and commitment were from high PC breach, low procedural and distributive justice and less respectful treatment from organisational representatives. The interaction between procedural justice and breach illustrates that breach may be forgivable if processes are fair. Surprisingly, a betrayal or "aggravated breach effect" may occur after a breach when interpersonal justice is high. Further, negative affectivity was negatively related to respondents' mental health (affective outcomes) but not commitment (work-related attitude). Healthcare organisations should ensure the fairness of decisions and avoid breaking promises within their control. If promises cannot reasonably be kept, transparency of processes behind the breach may allow allied health professionals to understand that the organisation did not purposefully fail to fulfil expectations. This study offers insights into how breach and four types of justice interact to influence employee mental health and work attitudes among allied health professionals.

    The reaction of uranium and plutonium carbides with austenitic steels has been studied between 650 and 1050 deg. C using UC, steel and (UPu)C, steel diffusion couples. The steels are of the type CN 18.10 with or without addition of molybdenum. The carbides used are hyper-stoichiometric. Tests were also carried out with UCTi, UCMo, UPuCTi and UPuCMo. Up to 800 deg. C no marked diffusion of carbon into stainless steel is observed. Between 800 and 900 deg. C the carbon produced by the decomposition of the higher carbides diffuses into the steel. Above 900 deg. C, decomposition of the monocarbide occurs according to a reaction which can be written schematically as: (U,PuC) + (Fe,Ni,Cr) {yields} (U,Pu) Fe{sub 2} + Cr{sub 23}C{sub 6}. Above 950 deg. C the behaviour of UPuCMo and that of the titanium (CN 18.12) and nickel (NC 38. 18) steels is observed to be very satisfactory.

  11. Overview of allied health personnel shortages.

    Upon learning that 95% of all fatal traffic accidents occur within three miles of one's home, an acquaintance moved to another residence four miles away and is still alive today. The world might be a much better place if most obstacles could be overcome this handily. Unfortunately, the problem of allied health personnel shortages appears to be more intractable. Because the situation is complicated in nature, it is most unlikely that any single remedy will suffice. Public and private interests have joined forces in many states, but it is abundantly clear that conventional market forces are unlikely to prevail. These forces usually focus on supply and demand. While shortages may cause entry-level salaries to rise, they do not stimulate academic institutions to increase their output nor will they affect the availability of research funding and/or doctoral training programs. Current market forces compel health facilities to engage in bidding wars for scarce manpower. Although individual job seekers may benefit, this practice does not increase the number of training program graduates. The federal government has a decisive role to play in assuring an adequate number of personnel to meet this nation's health care needs. Assistance is necessary in the form of providing entry- and advanced-level traineeships to accelerate the flow of part-time students pursuing doctorates, and to fund model student recruitment/retention projects. This role should encompass attracting students (particularly from minority and underserved portions of the population) to academic programs. The Disadvantaged Minority Health Improvement Act, PL 101-527 that was enacted in November 1990, contains only minimal provisions for allied health. Eligibility for student scholarship assistance is restricted to a small handful of allied health professions. Moreover, allied health is not eligible for the loan repayment program aimed at individuals who agree to serve on the faculty of health professions

    Architectural distortion is a suspicious abnormality for the diagnosis of breast cancer. The aim of this study was to investigate the clinical significance of sonographic ally detected architectural distortion. From January 2006 to June 2008, 20 patients were identified who had sonographic ally detected architectural distortions without a history of trauma or surgery and abnormal mammographic findings related to an architectural distortion. All of the lesions were pathologically verified. We evaluated the clinical and pathological findings and then assessed the clinical significance of the sonographic ally detected architectural distortions. Based on the clinical findings, one (5%) of the 20 patients had a palpable lump and the remaining 19 patients had no symptoms. No patient had a family history of breast cancer. Based on the pathological findings, three (15%) patients had malignancies. The malignant lesions included invasive ductal carcinomas (n = 2) and ductal carcinoma in situ (n = 1). Four (20%) patients had high-risk lesions: atypical ductal hyperplasia (n = 3) and lobular carcinoma in situ (n = 1). The remaining 13 (65%) patients had benign lesions, however, seven (35%) out of 13 patients had mild-risk lesions (three intraductal papillomas, three moderate or florid epithelial hyperplasia and one sclerosing adenosis). Of the sonographic ally detected architectural distortions, 35% were breast cancers or high-risk lesions and 35% were mild-risk lesions. Thus, a biopsy might be needed for an architectural distortion without an associated mass as depicted on breast ultrasound, even though the mammographic findings are normal

    In the latest of a line of joint ventures in its plastics business, Allied Signal has reached agreement with Mitsubishi Gas Chemical (MGC) to jointly develop thermoset cyanate ester resins and blends. The deal will involve further development of Allied Signal's Primaset phenol-formaldehyde cyanate ester resins, a new entrant in the thermoset arena. Although the Primaset resins were discovered in the 1960s, this would be the first time they are available commercially. The deal will marry Primaset technology with MGC's Skylex bisphenol A cyanate ester resins, says Fred DiAntonis, director/advanced materials at Allied Signal. The two firms are looking at marketing blends of the two materials. The potential market for these resins, used commercially by the electronics industry in printed circuit boards and by the aerospace industry in composites, is significant, says Robert P. Viarengo, Allied Signal president/performance materials. By aligning ourselves with MGC, the world leader in cyanate ester resin, we anticipate moving forward aggressively. The main competitor is Ciba, which acquired bisphenol A cyanate ester resins with its purchase of Rhone-Poulenc's high temperature resins business. DiAntonis estimates the market for cyanate ester resins could be worth $150 million by the end of the decade, although development costs have been in the tens of millions of dollars range

    2010-11-01

    Full Text Available As ally movements become an increasingly prevalent element of social justice efforts, research is needed that illuminates effective strategies to initially engage members of privileged social groups in anti-oppression work. This study presents descriptive findings regarding ally engagement strategies and barriers from a qualitative study of a particular ally movement – male anti-violence against women activism. Twenty-seven men who recently initiated involvement in an organization or event dedicated to ending sexual or domestic violence were interviewed regarding their perceptions of effective approaches to reaching and engaging other men in anti-violence work. Participants viewed tailored engagement strategies that tap into existing social networks, that allow men to see themselves reflected in anti-violence movements, and that help men make personal, emotional connections to the issue of violence as most effective. Implications for engaging men in the project of ending violence against women, and for ally movements more generally are discussed.

    Les traitements thermiques de surfaces sont des procedes qui visent a conferer au coeur et a la surface des pieces mecaniques des proprietes differentes. Ils permettent d'ameliorer la resistance a l'usure et a la fatigue en durcissant les zones critiques superficielles par des apports thermiques courts et localises. Parmi les procedes qui se distinguent par leur capacite en terme de puissance surfacique, le traitement thermique de surface au laser offre des cycles thermiques rapides, localises et precis tout en limitant les risques de deformations indesirables. Les proprietes mecaniques de la zone durcie obtenue par ce procede dependent des proprietes physicochimiques du materiau a traiter et de plusieurs parametres du procede. Pour etre en mesure d'exploiter adequatement les ressources qu'offre ce procede, il est necessaire de developper des strategies permettant de controler et regler les parametres de maniere a produire avec precision les caracteristiques desirees pour la surface durcie sans recourir au classique long et couteux processus essai-erreur. L'objectif du projet consiste donc a developper des modeles pour predire le profil de durete dans le cas de traitement thermique de pieces en acier AISI 4340. Pour comprendre le comportement du procede et evaluer les effets des differents parametres sur la qualite du traitement, une etude de sensibilite a ete menee en se basant sur une planification experimentale structuree combinee a des techniques d'analyse statistiques eprouvees. Les resultats de cette etude ont permis l'identification des variables les plus pertinentes a exploiter pour la modelisation. Suite a cette analyse et dans le but d'elaborer un premier modele, deux techniques de modelisation ont ete considerees, soient la regression multiple et les reseaux de neurones. Les deux techniques ont conduit a des modeles de qualite acceptable avec une precision d'environ 90%. Pour ameliorer les performances des modeles a base de reseaux de neurones, deux

    Nous proposons une méthodologie de mesure automatique de la surface de plasticité pendant des chargements cycliques biaxiaux. La surface de plasticité est mesurée de manière discrète avec un faible offset de déformation plastique (2 10^{-5}) et des paramètres de mesure optimisés. La méthode est appliquée à un acier inoxydable duplex soumis à un trajet de chargement non-proportionnel. Les résultats montrent une distorsion et une translation de la surface de plasticité sans changement de taille. La méthode présentée permet également de vérifier la normalité de la vitesse d'écoulement plastique par rapport à la surface de plasticité.

La caractérisation mécanique par essais de traction à haute température montre un important puits de ductilité entre environ 700 ∘C et environ 950 ∘C. L'observation au MEB des éprouvettes de traction indique que, dans la gamme de température observée pour laquelle il y a fragilisation, on a mouillage intergranulaire des joints de grains de l'acier à l'interface acier/revêtement par des films de Zn. La corrélation entre mouillage intergranulaire thermiquement activé d'une part, et propagation de fissure lors du chargement d'autre part, est discutée. This study deals with liquid zinc embrittlement for electro-galvanized steel. Mechanical characterization by high temperature tensile tests shows a drastic loss of ductility between 700 ∘C and 950 ∘C. SEM investigations show that steel grain boundaries under the steel/coating interface are penetrated by a liquid Zn channel, only in the temperature range of embrittlement. A correlation can be drawn between i thermal activated-grain boundary wetting and ii crack propagation in presence of external stress.

    This executive summary for Section 5 of the "Advancing Dental Education in the 21 st Century" project addresses the current and future educational systems for dental assisting, dental hygiene, dental therapy, and dental laboratory technology. Nineteen experts prepared six background articles on the educational changes necessary for future roles and practices. The key issues addressed relate to delivery system changes, educational curricula, scopes of practice, regulatory measures, and the public's oral health. The major finding is that substantial reforms will be needed to adequately prepare allied oral health professionals for the changes anticipated in 2040. A reconsideration of current accreditation guidelines, more flexibility with scopes of practice, and an adherence to rigorous academic programs are essential elements for the future of these professions.

    Research evidence is required to guide optimal allied health practice and inform policymakers in primary health care. Factors that influence a positive research culture are not fully understood, and nor is the impact of a positive research culture on allied health professionals. The aim of this systematic review was to identify factors that affect allied health research culture and capacity. An extensive search of 11 databases was conducted in June 2015. Studies were included if they were published in English, had full-text availability and reported research findings relating to allied health professions. Study quality was evaluated using the McMaster Critical Review Forms. Fifteen studies were eligible for inclusion. A meta-analysis was not performed because of heterogeneity between studies. Allied health professionals perceive that their individual research skills are lower in comparison to their teams and organisation. Motivators for conducting research for allied health professionals include developing skills, increasing job satisfaction and career advancement. Barriers include a lack of time, limited research skills and other work roles taking priority. Multilayered strategies, such as collaborations with external partners and developing research leadership positions, aimed at addressing barriers and enablers, are important to enhance allied health research culture and capacity.

    Evidence in the literature suggests job satisfaction can make a difference in keeping qualified workers on the job, but little research has been conducted focusing specifically on allied health faculty. In order to attract and retain top quality faculty, colleges and universities should understand the variables impacting faculty satisfaction and develop a plan to enhance satisfaction. An integrative literature review (CINHAL, ERIC, Journal of Allied Health, Chronicle of Higher Education, Research in Higher Education, and current books on job satisfaction) of faculty job satisfaction and dissatisfaction produced a variety of publications presenting the key determinants of job satisfaction by allied health faculty in the United States. The purpose of the analysis was to examine the various factors that influence job satisfaction, especially by allied health faculty, in institutions of higher education in the U.S. The procedure used for this analysis consisted of reviewing allied health and higher education faculty studies to identify factors influencing job satisfaction, research questions, sample size reported, instruments used for measurement of job satisfaction, and job satisfaction results. While the theoretical models of allied health and higher education faculty job satisfaction exist separately in the literature, their remarkable similarities permit the prospect of a contemporary framework of the essential components of job satisfaction. Potential opportunities for continuing research on the personal and professional variables impacting job satisfaction of allied health faculty and similar disciplines are presented.

    Academic units of allied health (eg, schools and colleges of allied health) are relatively new to institutions of higher education. As a result, the academic units lack prestige with private funding sources. This article describes a development model for raising private contributions emphasizing allied health academic units. The roles of the academic department, development advisory committee, and faculty in developing the mission statement, needs, objectives, and case statement for the department are described. How the department chairperson, faculty, dean, and advisory committee members interact with the staff from a development office in identifying, cultivating, and soliciting private support are explained.

    This study focused on the factors that influence students' choice of an allied health profession. A survey of 153 students in three allied health programs at the University of Connecticut revealed that "the need to help others," "prestige," "professional autonomy," "opportunities for advancement," "income potential," and "the effect of the specialty on family and personal life," were the major influencers of career choice among allied health students. Only a few students regarded malpractice suits and AIDS as negative influencers. While medical laboratory science majors regarded these as important factors, dietetics and physical therapy majors did not. The article suggests further use of these findings by program directors and career counselors.

    1975-01-01

    All operators at Allied-General Nuclear Services are initially trained in the basic concepts of radiation and radiation protection, they are drilled in the basic technical tools needed for further training, they are instructed in the design and operation of the Barnwell Nuclear Fuel Plant, and they are introduced to the actual operations via operating procedures. This all occurs during the Before-the-Baseline training phase and then the operators move on Beyond-the-Baseline. There they physically learn how to do their job at their own pace using checklists as a guide. All operators are then internally certified. Progression is based on demonstrated ability and those that qualify go on to jobs requiring NRC licenses. Upon internal certification, retraining commences immediately and will continue in its four month, one year, and two year cycles. Current feedback from the various classes that have completed the courses and are now in the retraining program indicates that this combination of initial technical training, on-the-job training, and retraining will produce and maintain effective, safe, and efficient operators

    1996-09-15

    The work on serrated flow in Al-Li alloys has given rise to a controversy--whether serrations in these alloys are caused by lithium atoms in solid solution or by {delta}{prime}(Al{sub 3}Li)-precipitates. This controversy calls for further work to clarify the mechanism of serrated flow in the Al-Li alloys. Kumar and McShane have shown that in an Al-2.5Li-2Mg-0.14Zr alloy, non-shearable {delta}{prime}-precipitates, which are obtained in the under-aged and peak-aged conditions, might directly initiate serrated flow. However, the latter result was ambiguous because of the presence of other alloying elements, and the need to work on a binary Al-Li alloy was emphasized. The present work discusses the results from the binary Al-Li alloys.

    Multiple technology based tools have been used to enhance skill development in allied health education, which now includes virtual learning environments. The purpose of this study was to explore whether, and how, this latest instructional technology is being adapted in allied health education. An online survey was circulated to all Association of Schools of Allied Health Professions (ASAHP) member institutions and focused on three broad areas of virtual learning environments: the uses of, the perceived pros and cons of, and the outcomes of utilizing them. Results show 40% (17 of 42) of the respondent use some form of the technology. The use of virtual learning technology in other healthcare professions (e.g., medicine) demonstrates the potential benefits to allied health education.

    Selker, L G; Vogt, M T

    1982-05-01

    The National Commission on Allied Health Education identified as one of its primary recommendations the need for increased numbers of women and minorities in leadership positions in allied health. The majority of allied health practitioners and students entering the allied health fields today are female. In these professions women tend to remain in direct line practice positions, while men typically occupy the managerial and executive positions. Much research and writing has appeared addressing how the traditional socialization process affects women's career patterns. The personal, interpersonal, and structural barriers that impede women's advancement into managerial positions have been reasonably well delineated. Much less attention has been directed toward how women who overcome these barriers function in managerial roles. Little work has been done on the functioning of males and females in administrative and managerial positions in academic settings. The research reported here involved a study of the perceived goal emphasis and time spent on the academic, administrative, and leadership functions by male and female allied health chairpersons. In this study male and female chairpersons were found to be remarkably similar in terms of emphasis and time spent on key departmental functions. The significance of these results is discussed relative to the traditional male/female socialization process. Recommendations are made about appropriate curricular modifications and professional/career development activities needed to encourage women to more readily accept leadership responsibilities in allied health during the 80s.

    According to the Croatian legislators, but not to the International (ISCO-08) and National (NKZ-10) Standard Classification of Occupations, university degree health professionals are limited to those individuals who have health-orientated education gained at the School of Medicine, School of Dental Medicine, Faculty of Pharmacy and Biochemistry, and study programs of Speech and Language Pathology. All other clinical scientists are considered as university degree non-health professionals who participate in diagnostic and therapeutic procedures, i.e. as allied health professionals. The objective of this paper is to discuss the status of university degree health associates within the Croatian health care system. The latest Ordinance on job titles/positions and coefficients of job complexity (i.e. basic salary coefficients) in public services provides only one coefficient (1.571) for clinical physicists, psychologists, biologists etc., and just three coefficients (1.445, 1.513, 1.571) for clinical engineers, social workers etc., at the bottom of the coefficients scale of all clinical staff completed different university studies of equal duration in years and/or workloads in European Credit Transfer and Accumulation System (ECTS) credits. Simultaneously, there are 30 coefficients (1.659-2.361) for health professionals, meticulously taking into account all possible combinations of their employment in state hospital/institute or not, obtained B.Sc., M.Sc. or Ph.D. degrees, titles of primarius, specialist or subspecialist, etc. Since 750 university degree health associates make currently only about 1 percent of the Croatian health workforce, any discrimination among clinical staff is unnecessary. Full regulation and appreciation of all professions, equal opportunities of continuing professional education and training, as well as career advancement (internship, residency, sub-specialization, postgraduate specialist programs, etc.) should be facilitated and provided to all

    The Victorian Assistant Workforce Model (VAWM) enables a systematic approach for the identification and quantification of work that can be delegated from allied health professionals (AHPs) to allied health assistants (AHAs). The aim of the present study was to explore the effect of implementation of VAWM in the community and ambulatory health care setting. Data captured using mixed methods from allied health professionals working across the participating health services enabled the measurement of opportunity for workforce redesign in the community and ambulatory allied health workforce. A total of 1112 AHPs and 135 AHAs from the 27 participating organisations took part in the present study. AHPs identified that 24% of their time was spent undertaking tasks that could safely be delegated to an appropriately qualified and supervised AHA. This equates to 6837h that could be redirected to advanced and expanded AHP practice roles or expanded patient-centred service models. The VAWM demonstrates potential for more efficient implementation of assistant workforce roles across allied health. Data outputs from implementation of the VAWM are vital in informing strategic planning and sustainability of workforce change. A more efficient and effective workforce promotes service delivery by the right person, in the right place, at the right time. What is known about this topic? There are currently workforce shortages that are predicted to grow across the allied health workforce. Ensuring that skill mix is optimal is one way to address these shortages. Matching the right task to right worker will also enable improved job satisfaction for both allied health assistants and allied health professionals. Workforce redesign efforts are more effective when there is strong data to support the redesign. What does this paper add? This paper builds on a previous paper by Somerville et al. with a case study applying the workforce redesign model to a community and ambulatory health care

    This report describes a fabricating method for cementation of a control rod with boron. The cementing is carried out by electrolysis of fused borax at about 900 Degree-Sign C, the steel rod to be cemented acting as a cathode, and the graphite electrode as an anode. As the electrolysis progresses, boron is deposited on/the steel rod and diffused into it. When suitable conditions of electrolysis exist, a case of the steel rod with as much as 20% boron content can easily be obtained. The kinds of steel investigated were carbon steel, stainless steels, high chrome steel etc., and each of them showed good results.

La cementation est effectuee par l'electrolyse de borax fondu a environ 900 Degree-Sign C, la barre d'acier a cementer formant cathode et une electrode en graphite constituant l'anode. Au cours du processus d 'electrolyse, le bore se depose sur la barre d'acier et est diffuse dans le metal. Lorsque l'electrolyse s'effectue dans les conditions requises, on peut obtenir facilement une barre d'acier dont la teneur en bore atteint jusqu'a 20%.

    Research evidence is required to guide best practice, inform policy and improve the health of communities. Current indicators consider allied health research culture to be low. This study aimed to measure the allied health research culture and capacity in a Victorian regional health service. The Research Capacity and Culture tool was used to evaluate research capacity and culture across individual, team and organisation domains. One-way ANOVA was used to determine differences between allied health professions, whereas responses to open-ended questions were themed using open coding. One hundred thirty-six allied health professionals completed the survey. There were statistically significant differences in the organisation domain between social work, physiotherapy and occupational therapy professions; in the team domain, between social work and all other professions. Motivators for conducting research included providing a high-quality service, developing skills and increasing job satisfaction. Barriers included other work roles taking priority, a lack of time and limited research skills. Multi-layered strategies including establishing conjoint research positions are recommended to increase allied health research culture in this regional area.

    Purpose A sound, scientific base of high quality research is needed to inform service planning and decision making and enable improved policy and practice. However, some areas of health practice, particularly many of the allied health areas, are generally considered to have a low evidence base. In order to successfully build research capacity in allied health, a clearer understanding is required of what assists and encourages research as well as the barriers and challenges. Participants and methods This study used written surveys to collect data relating to motivators, enablers, and barriers to research capacity building. Respondents were asked to answer questions relating to them as individuals and other questions relating to their team. Allied health professionals were recruited from multidisciplinary primary health care teams in Queensland Health. Eighty-five participants from ten healthcare teams completed a written version of the research capacity and culture survey. Results The results of this study indicate that individual allied health professionals are more likely to report being motivated to do research by intrinsic factors such as a strong interest in research. Barriers they identified to research are more likely to be extrinsic factors such as workload and lack of time. Allied health professionals identified some additional factors that impact on their research capacity than those reported in the literature, such as a desire to keep at the “cutting edge” and a lack of exposure to research. Some of the factors influencing individuals to do research were different to those influencing teams. These results are discussed with reference to organizational behavior and theories of motivation. Conclusion Supporting already motivated allied health professional individuals and teams to conduct research by increased skills training, infrastructure, and quarantined time is likely to produce better outcomes for research capacity building investment.

    Research positions embedded within healthcare settings have been identified as an enabler to allied health professional (AHP) research capacity; however, there is currently limited research formally evaluating their impact. In 2008, a Health Practitioner industrial agreement funded a research capacity building initiative within Queensland Health, Australia, which included 15 new allied health research positions. The present project used a qualitative and realist approach to explore the impact of these research positions, as well as the mechanisms which facilitated or hindered their success within their respective organisations. Forty-four AHP employees from six governmental health services in Queensland, Australia, participated in the study. Individual interviews were undertaken, with individuals in research positions (n = 8) and their reporting line managers (n = 8). Four stakeholder focus groups were also conducted with clinicians, team leaders and professional heads who had engaged with the research positions. Nine key outcomes of the research positions were identified across individual, team/service and organisational/community levels. These outcomes included clinician skill development, increased research activity, clinical and service changes, increased research outputs and collaborations, enhanced research and workplace culture, improved profile of allied health, development of research infrastructure, and professional development of individuals in the research positions. Different mechanisms that influenced these outcomes were identified. These mechanisms were grouped by those related to the (1) research position itself, (2) organisational factors and (3) implementation factors. The present findings highlight the potential value of the research positions for individuals, teams and clinical services across different governmental healthcare services, and demonstrate the impact of the roles on building the internal and external profile of allied health

    This paper deals with the effects of hydrogen on stainless steel, that might possibly be used as a canning material in hydrogen-cooled reactors. Apparent ultimate-tensile strength is only 80 per cent of initial value for hydrogen content about 50 cc NTP/ 100 g, and reduction in area decreases from 80 to 55 per cent. A special two-stage replica technique has been developed which allows fracture surface of small tensile specimens (about 0.1 mm diam.) to be examined in an electron microscope. All the specimens showed evidence of ductile character throughout the range of hydrogen contents investigated, but the aspect of the fracture surfaces gradually changes with increasing amounts. (author) [French] On etudie les effets de l'hydrogene sur des aciers inoxydables, qui sont des materiaux de gainage possibles pour des reacteurs utilisant l'hydrogene comme gaz de refroidissement. On montre que la charge apparente de rupture a la traction n'est plus que 80 pour cent de sa valeur initiale lorsque la teneur en hydrogene atteint 50 cc TPN/ 100 g, et que la striction passe dans ces conditions de 80 a 55 pour cent. L'examen microfractographique qui a ete effectue avec succes par une technique de double replique malgre la petitesse des echantillons (0,3 mm de diametre environ), revele que tout en gardant un caractere ductile, l'aspect des surfaces de rupture evolue notablement avec la teneur en hydrogene.

    Full text: Gamma radiation processing in the last 4-5 decades is continuously gaining importance in processing of a wide variety of products, as it can modify physical, chemical and biological properties of the materials, including food and allied products on industrial scale due its inherent qualities like ease of processing in finally packaged form, eco-friendly nature and other obvious reasons over conventional means of processing. Food and allied products are either from agricultural produce or animal origin; they get easily contaminated from soil during harvesting, handling, processing, environment conditions, storage and transport from various types of micro-organisms including pathogens. In many countries it is mandatory to bring down the population of micro-organisms to an acceptable level and complete elimination of pathogens before such products are accepted for human or animal consumption. Processing of food and allied products by radiation has its own challenges due to wider public acceptance of irradiated food, a wide range, 0.25-50kGy, of absorbed dose requirements for different category of such products and purposes, use of a variety of packaging materials in different shapes and sizes and because of its perishable nature. More than 50 countries including India in the world have accepted radiation processing of food and allied products by radiation. Dosimetry is an important aspect of radiation processing, whether it is food or allied product. Uniformity in dose delivered to these products depends on several factors such as product carrier to source frame alignment, product carrier and product/tote box design, product loading pattern, attenuation due to product thickness, product bulk density that varies from 0.1-1.0 kg/l and the plant design whether during processing product overlaps the source or otherwise. In this presentation dosimetric aspects of radiation processing of food and allied products and problems associated with dosimetry of such

    Uptake of e-health, the use of information communication technologies (ICT) for health service delivery, in allied health appears to be lagging behind other health care areas, despite offering the potential to address problems with service access by rural and remote Australians. The aim of the study was to conduct a scoping review of studies into the application of or attitudes towards ehealth amongst allied health professionals conducted in Australia. Studies meeting inclusion criteria published from January 2004 to June 2015 were reviewed. Professions included were audiology, dietetics, exercise physiology, occupational therapy, physiotherapy, podiatry, social work, and speech pathology. Terms for these professions and forms of ehealth were combined in databases of CINAHL (EBSCO), Cochrane Library, PsycINFO (1806 - Ovid), MEDLINE (Ovid) and AMED (Ovid). Forty-four studies meeting inclusion criteria were summarised. They were either trials of aspects of ehealth service delivery, or clinician and/or client use of and attitudes towards ehealth. Trials of ehealth were largely from two research groups located at the Universities of Sydney and Queensland; most involved speech pathology and physiotherapy. Assessments through ehealth and intervention outcomes through ehealth were comparable with face-to-face delivery. Clinicians used ICT mostly for managing their work and for professional development, but were reticent about its use in service delivery, which contrasted with the more positive attitudes and experiences of clients. The potential of ehealth to address allied health needs of Australians living in rural and remote Australia appears unrealised. Clinicians may need to embrace ehealth as a means to radicalise practice, rather than replicate existing practices through a different mode of delivery.

    Research on heterosexual allies has focused on heterosexual identity development models and pathways to ally activism. The positive aspects or positive experiences of identifying as an ally to lesbian, gay, bisexual, and transgender (LGBT) identified individuals and communities have received little attention. Using an online survey of participants recruited from LGBT ally related social media, we collected open-ended responses to a question about the positive aspects of self-identifying as a heterosexual ally. A final analytic sample of 292 self-identified male and female heterosexual adults (age 18-71, M = 33.47, SD = 13.32) provided responses that generated 8 themes. Positive aspects of being a heterosexual ally were: (a) increased knowledge and awareness, (b) upholding values of justice, (c) beneficial individual relationships, (d) community belonging, (e) educating others, (f) being a role model, (g) using social privilege, and (h) speaking out and taking a stand. The findings suggest that being a heterosexual ally is rewarding and may enhance individual well-being. These findings provide information that may contribute to effective ally development efforts.

    Preparation for responding to emergency events that does not warrant outside help beyond the local community resources or responding to disaster events that is beyond the capabilities of the local community both require first responders and healthcare professionals to have interdisciplinary skills needed to function as a team for saving lives. To date, there is no core emergency preparedness and disaster planning competencies that have been standardized at all levels across the various allied health curricula disciplines. To identify if emergency preparedness and disaster training content are currently being taught in allied health program courses, to identify possible gaps within allied health curricula, and to explore the perceptions of allied health college educators for implementing emergency preparedness and disaster training core competencies into their existing curricula, if not already included. A quantitative Internet-based survey was conducted in 2013. Convenient sample. Fifty-one allied health college educators completed the survey. Descriptive statistics indicated that the majority of allied health college instructors do not currently teach emergency preparedness and disaster training core competency content within their current allied health discipline; however, their perceived level of importance for inclusion of the competencies was high. The results of this study supported the need for developing and establishing a basic national set of standardized core emergency preparedness and disaster planning competencies at all levels across various allied health curricula disciplines to ensure victims receive the best patient care and have the best possible chance of survival.

    Measles, a virus borne droplet infection, is one of the leading causes of death among young children worldwide despite presence of a safe and cost-effective vaccine. Objective of our study was to identify the characteristics of measles patients admitted to Allied Hospitals, Rawalpindi. Methods: This cross-sectional study was conducted amongst patients admitted with measles in paediatric units of Rawalpindi Medical College Allied Hospitals, Rawalpindi. A standard proforma was used to collect data from the respondents. Results: A total of 55 patients (mean age-29.36 months) with measles were included in the study. 65.5% children were vaccinated while 34.5% were not vaccinated. Among those vaccinated 14 were male. Out of the vaccinated children 52.6% were residents of middle class areas, 31.6% lower middle class area, 10.5% upper middle class areas and 5.3% rural areas. In 55.0% of patients who were vaccinated with at least one dose of measles at nine month of age the estimated calendar months of vaccination was March to April while in 30% the overall climatic period of vaccination was of summer (May to September). Twenty one study subjects were exposed to a case of measles in the family and thirty five out of all developed at least one known complication of the disease. Pneumonia was the most common complication reported in patients (63.6%) followed by diarrhoea (27.3%). Conclusion: Majority of the patients suffering from measles were not vaccinated and the most common reason for failure to immunize children was lack of awareness. Educated and well off fathers were more likely to get their children immunized. The vaccinated children who developed measles majority were vaccinated during months of March, April and May. (author)

  19. Using the Primary Literature in an Allied Health Microbiology Course

    2009-12-01

    Full Text Available A strategy was adapted for using the primary literature to foster active learning in an allied health microbiology course. Recent journal articles were selected that underscored the fundamental microbiological principles to be learned in each course unit. At the beginning of the semester, students were taught the relationship between the layout of scientific articles and the scientific method. During the rest of the semester, students were oriented to the topic of each paper by viewing videos from Unseen Life on Earth: an Introduction to Microbiology, reading assigned pages from the text, and participating in mini-lectures and discussions. After all preparatory material was completed, a paper was read and discussed in small groups and as a class. Students were assessed using daily reading quizzes and end-of-unit concept quizzes. While reading quizzes averaged approximately 93%, concept quiz grades averaged approximately 82%. Student recognition of the terms used in each unit’s scientific article was assessed with pre-read and post-read wordlists. For the self-assessment, the percent change between pre-read and post-read word cognition was, as expected, highly significant. Approximately 80% of students agreed that reading the scientific articles was a valuable part of the class and that it provided meaning to their study of microbiology. Using the primary scientific literature facilitated active learning in and out of the classroom. This study showed that introducing the scientific literature in an allied health microbiology class can be an effective way of teaching microbiology by providing meaning through the current literature and understanding of the scientific method.

    A cooperative investigation was conducted to evaluate Al-Cu-Mg-Li alloy 1441 for long service life fuselage applications. Alloy 1441 is currently being used for fuselage applications on the Russian Be- 103 amphibious aircraft, and is expected to be used for fuselage skin on a new Tupolev business class aircraft. Alloy 1441 is cold-rollable and has several attributes that make it attractive for fuselage skin applications. These attributes include lower density and higher specific modulus with similar strength as compared to conventional Al-Cu-Mg alloys. Cold-rolled 1441 Al-Li sheet specimens were tested at NASA Langley research center (LaRC) and at the All-Russia Institute of Aviation Materials (VIAM) in Russia to evaluate tensile properties, fracture toughness, impact resistance, fatigue life and fatigue crack growth rate. In addition, fuselage panels were fabricated by Tupolev Design Bureau (TDB) using 1441 skins and Al-Zn-Mg-Cu alloy stiffeners. The panels were subjected to cyclic pressurization fatigue tests at TDB and at LaRC to simulate fuselage pressurization/depressurization during aircraft service. This paper discusses the results from this investigation. (orig.)

    2007-11-01

    A central recommendation from the Pew Health Commission to educators has been to empower future care providers to function effectively as teams. Administrators and faculty members within a school of allied health sciences thus established an interdisciplinary program where students would learn to function as team members and demonstrate competencies required for practice in diverse, demanding, and continually changing health care environments. Students from five disciplines have participated in featured events, mentored activities and capstone projects, earning credit in an interdisciplinary course of study that complements offerings in their home disciplines. This follow-up article reports on the progress and development since 2002 of an interdisciplinary program known as Team IDEAL. Formative evaluation measures used to assess satisfaction with the program are presented alongside a discussion of new directions. Team IDEAL will move forward in a streamlined form that reflects its central aim. IDEAL leadership will remain cognizant of the effects of discipline-specific curricular changes, complex programming, and student perspectives on the process interdisciplinary education.

    2007-01-01

    Professional behaviors are an integral part of clinical practice in all allied health and medical fields. A systematic process for instruction, the education, and development of professional behaviors, cannot be taught in the same way that memorization of human anatomy or medical terminology is taught. One cannot expect professional behaviors to just appear in an individual upon graduation and entry into a health care field. Professional behavior development is an essential component of physical therapy professional education and is clearly defined through the guiding documents of the American Physical Therapy Association, which include 'A Normative Model of Physical Therapist Professional Education,' 'Evaluative Criteria for Accreditation of Education Programs for the Preparation of Physical Therapists,' and the 'Guide to Physical Therapist Practice.' Building a comprehensive and progressive curricular thread for professional behaviors can pose a challenge for a professional program and the core faculty. This paper will present a curricular model of weaving professional behaviors into a core entry-level professional curriculum using a specific curricular thread, activities for different levels of students, and assessment at each point in the path. This paper will demonstrate the potential for universal application of a professional behaviors.

    After having developed one of the first thermo-balances to operate under pressure, we have studied the influence of the pressure on the corrosion of iron and steels by carbon dioxide. The corrosion was followed by three different methods simultaneously: by the oxidation kinetics, by micrographs, and by radiocrystallography. We have been able to show that the influence of the pressure is not negligible and we have provided much experimental evidence: oxidation kinetics, micrographic aspects, surface precipitation of carbon, metal carburization, the texture of the magnetite layer. All these phenomena are certainly modified by changes in the carbon dioxide pressure. In order to interpret most of our results we have been led to believe that the phenomenon of corrosion by CO{sub 2} depends on secondary reactions localised at the oxide-gas interface. This would constitute a major difference between the oxidation by CO{sub 2} and that by oxygen. (author) [French] Apres avoir etudie et mis au point une des premieres thermobalances fonctionnant sous pression, nous avons etudie l'influence de la pression sur la corrosion du fer et des aciers par l'anhydride carbonique.

Tous ces phenomenes sont sans aucun doute modifies par une variation de pression du gaz carbonique. Pour interpreter la plupart de nos resultats, nous avons ete conduits a penser que le phenomene de corrosion par CO{sub 2} etait tributaire de reactions secondaires localisees a l'interface oxyde-gaz.

    Inpatient care is dependent upon the effective transfer of clinical information across multiple professions. However, documented patient clinical information generated by different professions is not always successfully transferred between them. One obstacle to successful information transfer may be the reader's perception of the information, which is framed in a particular professional context, rather than the information per se. The aim of this research was to investigate how different health professionals perceive allied health documentation and to investigate how clinicians of all experience levels across medicine, nursing and allied health perceive and use allied health notes to inform their decision-making and treatment of patients. The study used a qualitative approach. A total of 53 speech pathologists, nurses, doctors, occupational therapists, dieticians and social workers (8 males; 43 females) from an Australian regional tertiary hospital participated in eleven single discipline focus groups, conducted over 4 months in 2012. Discussions were recorded and transcribed verbatim and coded into themes by content analysis. Six themes contributing to the efficacy of clinical information transference emerged from the data: day-to-day care, patient function, discharge and discharge planning, impact of busy workloads, format and structure of allied health documentation and a holistic approach to patient care. Other professions read and used allied health notes albeit with differences in focus and need. Readers searched for specific pieces of information to answer their own questions and professional needs, in a process akin to purposive sampling. Staff used allied health notes to explore specific aspects of patient function but did not obtain a holistic picture. Improving both the relationship between the various health professions and interpretation of other professions' documented clinical information may reduce the frequency of communication errors, thereby

    The aim of the present study was to identify areas where allied health assistants (AHAs) are not working to their full scope of practice in order to improve the effectiveness of the allied health workforce. Qualitative data collected via focus groups identified suitable AHA tasks and a quantitative survey with allied health professionals (AHPs) measured the magnitude of work the current AHP workforce spends undertaking these tasks. Quantification survey results indicate that Victoria's AHP workforce spends up to 17% of time undertaking tasks that could be delegated to an AHA who has relevant training and adequate supervision. Over half this time is spent on clinical tasks. The skills of AHAs are not being optimally utilised. Significant opportunity exists to reform the current allied health workforce. Such reform should result in increased capacity of the workforce to meet future demands.

    The corrosion of austenitic stainless steels in boiling nitric acid markedly increases when the medium contains hexavalent chromium ions. Because of several redox phenomena, the potential of the steel generally changes in course of time. Measurements show a relation between the weight loss and the potential of specimens. Additions of Mn(VII) and Ce(IV) are compared with that of Cr(VI), and show that the relation is a general one. The attack cf the metal in oxidizing media is largely intergranular, leading to exfoliation of the grains, although the steel studied is not sensitive to the classical Huey and Strauss tests. Also even in the absence of any other oxidizing reaction, the current density observed when the steel is anodically polarized under potentiostatic conditions does not correspond to the actual weight loss of the metal. (authors) [French] La corrosion d'aciers inoxydables austenitiques en milieu nitrique bouillant augmente notablement quand le milieu contient des ions chrome a l'etat hexavalent. Par suite de divers phenomenes d'oxydo-reduction, le potentiel de l'acier evolue generalement au cours du temps. Les mesures effectuees permettent d'etablir une relation entre les pertes de poids et le potentiel des echantillons. L'addition de Mn(VI) et Ce(IV) est compare a celle de Cr(VI) et montre que la relation precedente s'applique de facon generale. L'attaque du metal en milieu oxydant est en grande, partie due a une corrosion intergranulaire conduisant a un dechaussement des grains bien que l'acier etudie ne soit pas sensible aux tests classiques de Huey et de Strauss. Aussi, meme en l'absence de toute autre reaction d'oxydation l'intensite qu l'on observerait en soumettant l'acier a un potentiel anodique dans un montage potentiostatique ne correspondrait pas a la perte de poids reelle du metal.

  18. Quality improvement – rival or ally of practice development?

    Directory of Open Access Journals (Sweden)

    Gavin Lavery

    2016-05-01

    Full Text Available The majority of nurses, doctors, allied health professionals and other healthcare staff possess a strong desire to provide the best possible care and experience for their patients. Unfortunately, this sometimes falls short of what was planned or intended (Institute of Medicine, 2001, p 23. The gap between care intended and care delivered can be explained by problems with systems and processes and/or people and culture. The narrowing of this gap is the focus of many strategies, methodologies and approaches. Practice development is described as ‘an activity focused on developing people and practice for the ultimate purpose of achieving high-quality person-centred care’ and a ‘methodology that aims to achieve effective workplace cultures that are person-centred’ (Shaw, 2012; Manley et al., 2014. Practice development undoubtedly has a strong focus on people and culture and the potential to change processes and systems. Another approach, widely referred to as quality improvement, aims to improve safety, effectiveness and person-centredness in healthcare using principles proven effective in other industries such as manufacturing – notably car manufacturing (Toyota, oil production, nuclear power and aviation. The fundamental principles of quality improvement for healthcare include making care reliable (every patient receiving care as intended every time, using well-designed processes and reducing variation (agreeing a consistent way to provide care. At first glance this may appear to be an approach suited only to systems and processes. However, better processes, designed by those who use them, resulting in fewer errors and less re-working or working around problems, can reduce stress on staff, offer greater job satisfaction with improved morale and free up time to provide person-centred care. In his report, A Promise to Learn – a Commitment to Act (2013, p 24, Professor Don Berwick says: ‘Mastery of quality and patient safety sciences and

    This study examined the impact of expanded function allied dental personnel on the productivity and efficiency of general dental practices. Detailed practice financial and clinical data were obtained from a convenience sample of 154 general dental practices in Colorado. In this state, expanded function dental assistants can provide a wide range of reversible dental services/procedures, and dental hygienists can give local anesthesia. The survey identified practices that currently use expanded function allied dental personnel and the specific services/procedures delegated. Practice productivity was measured using patient visits, gross billings, and net income. Practice efficiency was assessed using a multivariate linear program, Data Envelopment Analysis. Sixty-four percent of the practices were found to use expanded function allied dental personnel, and on average they delegated 31.4 percent of delegatable services/procedures. Practices that used expanded function allied dental personnel treated more patients and had higher gross billings and net incomes than those practices that did not; the more services they delegated, the higher was the practice's productivity and efficiency. The effective use of expanded function allied dental personnel has the potential to substantially expand the capacity of general dental practices to treat more patients and to generate higher incomes for dental practices.

  20. Evidence-based practice curriculum in allied health professions for teaching-research-practice nexus.

    Asokan, G V

    2012-11-01

    Allied healthcare workers are from diverse professions and the key skill required is providing evidence-based care but this concept has not permeated enough for using it skillfully in their professions. A well structured curriculum in allied health professions is needed to strengthen concerted teaching, research, and practice to empower their professionals and make considerable differences in the lives of people by adopting evidence-based practice. Information sources for allied health professionals have relied on advice of their supervisors and colleagues, personal experiences, authoritative theory and texts for practice. Because of "research-practice" gap, often the use of evidence is not reflected in an individual day to day professional practice. Although allied health professionals work in resource and evidence challenged settings, there are certain barriers and facilitators, which need to be addressed. To implement practice-related research findings and uptake of evidence requires two essential components, namely, practical component and knowledge component. Research bench marking and research metrics for quality assurance and standardization through evidence-based practice will promote academic status and credibility of allied health profession. © 2012 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

  1. Complex interventions required to comprehensively educate allied health practitioners on evidence-based practice

    Full Text Available Janine Margarita Dizon1,2, Karen Grimmer-Somers11International Centre for Allied Health Evidence, University of South Australia, Adelaide, SA, Australia; 2University of Santo Tomas, Manila, PhilippinesAbstract: There is currently no strong evidence regarding the most effective training approach for allied health professionals that will support them to consistently apply the best research evidence in daily practice. Current evidence-based practice training tends to be 'one size fits all', and is unlikely to be appropriate for all allied health disciplines because of the variability in their tasks and scope of practice. The scant body of evidence regarding the effectiveness of evidence-based practice training for allied health practitioners provides some support for improving knowledge and skills, but equivocal evidence about influencing behaviors and attitudes. We propose a new model of evidence-based practice training, based on the concept of complex interventions reported in the literature. We believe that by offering training in evidence-based practice based on complex interventions relevant to the needs of the attendees, using fixed and variable components, there may be greater success in significantly influencing knowledge skills, attitudes, and behaviors.Keywords: complex interventions, evidence-based practice training, allied health

  2. American alliances and nuclear non-proliferation. The end of nuclear weapon activities of US allies

    International Nuclear Information System (INIS)

    Schneider, Jonas

    2016-01-01

    Jonas Schneider tackles a question that is of great interest both to scholars of nuclear proliferation and to practitioners of nonproliferation diplomacy: Why do some political leaders of U.S. allies agree to abandon their nation's nuclear weapons activities, while others - who are often members of the same allied government and sometimes even of the same political party - steadfastly reject such a course reversal? Our existing stock of theories does not fare well in accounting for this important variation in leaders' attitudes. To solve this puzzle, Schneider develops an innovative theory that draws on the individual status conceptions of allied political leaders. Subsequently, the author undertakes to test his theory using four thoroughly researched case studies, and he derives important lessons for international nonproliferation diplomacy toward the Middle East and Northeast Asia.

  3. Measuring rural allied health workforce turnover and retention: what are the patterns, determinants and costs?

    2011-04-01

    To measure variations in patterns of turnover and retention, determinants of turnover, and costs of recruitment of allied health professionals in rural areas. Data were collected on health service characteristics, recruitment costs and de-identified individual-level employment entry and exit data for dietitians, occupational therapists, physiotherapists, podiatrists, psychologists, social workers and speech pathologists employed between 1 January 2004 and 31 December 2009. Health services providing allied health services within Western Victoria were stratified by geographical location and town size. Eighteen health services were sampled, 11 participated. Annual turnover rates, stability rates, median length of stay in current position, survival probabilities, turnover hazards and median costs of recruitment were calculated. Analysis of commencement and exit data from 901 allied health professionals indicated that differences in crude workforce patterns according to geographical location emerge 12 to 24 months after commencement of employment, although the results were not statistically significant. Proportional hazards modelling indicated profession and employee age and grade upon commencement were significant determinants of turnover risk. Costs of replacing allied health workers are high. An opportunity for implementing comprehensive retention strategies exists in the first year of employment in rural and remote settings. Benchmarks to guide workforce retention strategies should take account of differences in patterns of allied health turnover and retention according to geographical location. Monitoring allied health workforce turnover and retention through analysis of routinely collected data to calculate selected indicators provides a stronger evidence base to underpin workforce planning by health services and regional authorities. © 2011 The Authors.

  4. Allie: a database and a search service of abbreviations and long forms

    Science.gov (United States)

    Yamamoto, Yasunori; Yamaguchi, Atsuko; Bono, Hidemasa; Takagi, Toshihisa

    2011-01-01

    Many abbreviations are used in the literature especially in the life sciences, and polysemous abbreviations appear frequently, making it difficult to read and understand scientific papers that are outside of a reader’s expertise. Thus, we have developed Allie, a database and a search service of abbreviations and their long forms (a.k.a. full forms or definitions). Allie searches for abbreviations and their corresponding long forms in a database that we have generated based on all titles and abstracts in MEDLINE. When a user query matches an abbreviation, Allie returns all potential long forms of the query along with their bibliographic data (i.e. title and publication year). In addition, for each candidate, co-occurring abbreviations and a research field in which it frequently appears in the MEDLINE data are displayed. This function helps users learn about the context in which an abbreviation appears. To deal with synonymous long forms, we use a dictionary called GENA that contains domain-specific terms such as gene, protein or disease names along with their synonymic information. Conceptually identical domain-specific terms are regarded as one term, and then conceptually identical abbreviation-long form pairs are grouped taking into account their appearance in MEDLINE. To keep up with new abbreviations that are continuously introduced, Allie has an automatic update system. In addition, the database of abbreviations and their long forms with their corresponding PubMed IDs is constructed and updated weekly.

    The recruitment and retention of allied health workers present challenges for organizations in Australia and internationally. Australia, in common with other developed countries, faces the prospect of a rapidly aging population and the high turnover of younger allied health workers (the majority of whom are female) from employing organizations. Emphases on the individual characteristics of Boomer, Generation X, and Generation Y workers may provide a useful starting base for recruitment and retention strategies, but our study shows that these need to be contextualized within broader political, social, and structural factors that take account of gender and the changing needs of workers over their life span.

  6. Mechanical properties of ultra-fine grained structure formed in Al-Li alloys

    International Nuclear Information System (INIS)

    Adamczyk-Cieslak, B.; Lewandowska, M.; Mizera, J.; Kurzydlowski, K.J.

    2004-01-01

    This paper describes the mechanical properties (microhardness, yield stress) of two model Al-Li alloys by the Equal-Channel-Angular-Extrusion (ECAE) process. The applied ECAE process reduced the grain size from an initial value of ∼300 μm to a value of ∼0.7 μm leading to profound increase of plastic flow resistance. Such an increase is related to the grain size refinement and strengthening due to Li atoms in solid solution. Microhardness data confirm the Hall - Petch relation for grain sizes not available so far in Al-Li alloys. (author)

    A great effort has been made for some Aluminum Industries since the ''80 to develop new alloys with weight reduction, to use in aeronautic industry. The system Al-Li is a good example of this effort, because it presents a low density and a greater stiffness than usual alloys. In this paper we compare some Al-Li alloys with respect to mechanical properties: fracture toughness and resistance to crack propagation on fatigue case. The results are discussed, as well as the nowadays status and perspectives for the use of these alloys. (author)

    2009-01-01

    Allied health professionals are integral to the effective delivery of hospital-based health care, yet little is known about the working conditions associated with the attitudinal and health outcomes of these employees. The purpose of this study was to investigate the extent to which the demand-control-support model, in combination with organizational justice variables, predicts the employee-level outcomes of allied health professionals. Allied health professionals from an Australian health care organization were surveyed, with 113 (52.6%) participating. The survey included measures of job demands, job control, social support, organizational justice, satisfaction, commitment and psychological distress. Multiple regression analyses reveal that the additive demand-control-support model predicts the outcome variables of job satisfaction, organizational commitment and psychological distress, whereas the organizational justice variables predicted organizational commitment and psychological distress. Further, both work and nonwork sources of support, in addition to specific justice dimensions, were closely associated with employee-level outcomes. When coupled with previous research involving social support and organizational justice, the findings from this study suggest that initiatives aimed at strengthening supervisor and nonwork support, while enhancing perceptions of organizational fairness, may offer useful avenues for increasing the levels of satisfaction, commitment and well-being experienced by allied health professionals.

    2011-06-01

    Full Text Available Abstract Background Knowledge translation (KT aims to close the gap between knowledge and practice in order to realize the benefits of research through (a improved health outcomes, (b more effective health services and products, and (c strengthened healthcare systems. While there is some understanding of strategies to put research findings into practice within nursing and medicine, we have limited knowledge of KT strategies in allied health professions. Given the interprofessional nature of healthcare, a lack of guidance for supporting KT strategies in the allied health professions is concerning. Our objective in this study is to systematically review published research on KT strategies in five allied health disciplines. Methods A medical research librarian will develop and implement search strategies designed to identify evidence that is relevant to each question of the review. Two reviewers will perform study selection and quality assessment using standard forms. For study selection, data will be extracted by two reviewers. For quality assessment, data will be extracted by one reviewer and verified by a second. Disagreements will be resolved through discussion or third party adjudication. Within each profession, data will be grouped and analyzed by research design and KT strategies using the Effective Practice and Organisation of Care Review Group classification scheme. An overall synthesis across professions will be conducted. Significance A uniprofessional approach to KT does not represent the interprofessional context it targets. Our findings will provide the first systematic overview of KT strategies used in allied health professionals' clinical practice, as well as a foundation to inform future KT interventions in allied healthcare settings.

    To design and establish reliability of a local stroke audit tool by engaging allied health clinicians within a privately funded hospital. Design: Two-stage study involving a modified Delphi process to inform stroke audit tool development and inter-tester reliability. Allied health clinicians. A modified Delphi process to select stroke guideline recommendations for inclusion in the audit tool. Reliability study: 1 allied health representative from each discipline audited 10 clinical records with sequential admissions to acute and rehabilitation services. Recommendations were admitted to the audit tool when 70% agreement was reached, with 50% set as the reserve agreement. Inter-tester reliability was determined using intra-class correlation coefficients (ICCs) across 10 clinical records. Twenty-two participants (92% female, 50% physiotherapists, 17% occupational therapists) completed the modified Delphi process. Across 6 voting rounds, 8 recommendations reached 70% agreement and 2 reached 50% agreement. Two recommendations (nutrition/hydration; goal setting) were added to ensure representation for all disciplines. Substantial consistency across raters was established for the audit tool applied in acute stroke (ICC .71; range .48 to .90) and rehabilitation (ICC.78; range .60 to .93) services. Allied health clinicians within a privately funded hospital generally agreed in an audit process to develop a reliable stroke audit tool. Allied health clinicians agreed on stroke guideline recommendations to inform a stroke audit tool.

    Disinvestment from inefficient or ineffective health services is a growing priority for health care systems. Provision of allied health services over the weekend is now commonplace despite a relative paucity of evidence supporting their provision. The relatively high cost of providing this service combined with the paucity of evidence supporting its provision makes this a potential candidate for disinvestment so that resources consumed can be used in other areas. This study aims to determine the effectiveness, cost-effectiveness and safety of the current model of weekend allied health service and a new stakeholder-driven model of weekend allied health service delivery on acute medical and surgical wards compared to having no weekend allied health service. Two stepped wedge, cluster randomised trials of weekend allied health services will be conducted in six acute medical/surgical wards across two public metropolitan hospitals in Melbourne (Australia). Wards have been chosen to participate by management teams at each hospital. The allied health services to be investigated will include physiotherapy, occupational therapy, speech therapy, dietetics, social work and allied health assistants. At baseline, all wards will be receiving weekend allied health services. Study 1 intervention will be the sequential disinvestment (roll-in) of the current weekend allied health service model from each participating ward in monthly intervals and study 2 will be the roll-out of a new stakeholder-driven model of weekend allied health service delivery. The order in which weekend allied health services will be rolled in and out amongst participating wards will be determined randomly. This trial will be conducted in each of the two participating hospitals at a different time interval. Primary outcomes will be length of stay, rate of unplanned hospital readmission within 28 days and rate of adverse events. Secondary outcomes will be number of complaints and compliments, staff absenteeism

    In order to establish a general method of analysis of stainless steels, by means of spark spectroscopy on solutions, a systematic study has been made of the factors involved. The variations in acidity of the solutions, or in the ratio of concentrations of two acids at constant pH, lead to a displacement of the calibration curve. Simple relations have been established between the concentration of the extraneous elements, and the effects produced, for the constituents Fe, Ti, Ni, Cr, Mn; a general method using abacus is proposed for steels containing only these elements. The interactions in the case of the elements Mo, Nb, Ta, W, were more complex, so that the simultaneous separation was studied with the help of ion-exchange resins. A general method of analysis is proposed for stainless steels.

  12. Mathematical modeling of the socalled Allis test: a field study in orthopedic confusion

    Full Text Available Abstract Background Chiropractors use a variety of supine and prone leg checking procedures. Some, including the Allis test, purport to distinguish anatomic from functional leg length inequality. Although the reliability and to a lesser extent the validity of some leg checking procedures has been assessed, little is known on the Allis test. The present study mathematically models the test under a variety of hypothetical clinical conditions. In our search for historical and clinical information on the Allis test, nomenclatural and procedural issues became apparent. Methods The test is performed with the subject carefully positioned in the supine position, with the head, pelvis, and feet centered on the table. After an assessment for anatomic leg length inequality, the knees are flexed to approximately 90°. The examiner then sights the short leg side knee sequentially from both the foot and side of the table, noting its relative locations: both its height from the table and Y axis position. The traditional interpretation of the Allis test is that a low knee identifies a short tibia and a cephalad knee a short femur. Assuming arbitrary lengths and a tibio/femoral ratio of 1/1.26, and a hip to foot distance that placed the knee near 90°, we trigonometrically calculated changes in the location of the right knee that would result from hypothetical reductions in tibial and femoral length. We also modeled changes in the tibio/femoral ratio that did not change overall leg length, and also a change in hip location. Results The knee altitude diminishes with either femoral or tibial length reduction. The knee shifts cephalad when the femoral length is reduced, and caudally when the tibial length is reduced. Changes in the femur/tibia ratio also influence knee position, as does cephalad shifting of the hip. Conclusion The original Allis (aka Galeazzi test was developed to identify gross hip deformity in pediatric patients. The extension of this test to

    The corrosion of austenitic stainless steels in boiling nitric acid markedly increases when the medium contains hexavalent chromium ions. Because of several redox phenomena, the potential of the steel generally changes in course of time. Measurements show a relation between the weight loss and the potential of specimens. Additions of Mn(VII) and Ce(IV) are compared with that of Cr(VI), and show that the relation is a general one. The attack cf the metal in oxidizing media is largely intergranular, leading to exfoliation of the grains, although the steel studied is not sensitive to the classical Huey and Strauss tests. Also even in the absence of any other oxidizing reaction, the current density observed when the steel is anodically polarized under potentiostatic conditions does not correspond to the actual weight loss of the metal. (authors) [French] La corrosion d'aciers inoxydables austenitiques en milieu nitrique bouillant augmente notablement quand le milieu contient des ions chrome a l'etat hexavalent. Par suite de divers phenomenes d'oxydo-reduction, le potentiel de l'acier evolue generalement au cours du temps. Les mesures effectuees permettent d'etablir une relation entre les pertes de poids et le potentiel des echantillons. L'addition de Mn(VI) et Ce(IV) est compare a celle de Cr(VI) et montre que la relation precedente s'applique de facon generale. L'attaque du metal en milieu oxydant est en grande, partie due a une corrosion intergranulaire conduisant a un dechaussement des grains bien que l'acier etudie ne soit pas sensible aux tests classiques de Huey et de Strauss. Aussi, meme en l'absence de toute autre reaction d'oxydation l'intensite qu l'on observerait en soumettant l'acier a un potentiel anodique dans un montage potentiostatique ne correspondrait pas a la perte de poids reelle du metal.

    Worcestershire Health Libraries provides services to all NHS and social care staff in Worcestershire. Despite intensive marketing, statistics showed low usage of the library service for professions allied to technical services and allied health professionals. To discover why there was low usage of the library services using qualitative techniques and to use focus groups as a marketing opportunity. This article also aims to outline the processes involved in delivering focus groups, the results gained, and the actions taken in response to the results. Focus groups were conducted in two departments, Pathology and Occupational Therapy. The Biochemistry department (part of Pathology) had two focus groups. An additional focus group was conducted for all the Pathology education leads. Occupational Therapy had two meetings, one for hospital based staff, and the other for community staff. Issues centred on registration, inductions, time, library ambience, multi-disciplinary service and resources. The findings raised marketing opportunities and the process identified potential candidates for the role of team knowledge officer, to act as library champions within departments. It also identified areas in which the library service was not meeting user needs and expectations, and helped focus service development. Focus groups allowed an opportunity to speak to non-users face to face and to discover, and where appropriate challenge both their, and library staff's pre-conceived ideas about the service. The information revealed gave an opportunity to market services based on user needs. © 2011 The authors. Health Information and Libraries Journal © 2011 Health Libraries Group.

    Incremental strain-rate and constant strain-rate cone-forming tests have been carried out at 450-550 C to investigate the superplastic forming characteristics of Al-Li-Cu-Mn, Al-Li-Cu-Mg-Zr, and Al-Li-Zn-Mg alloys processed by powder-metallurgy (P/M) and ingot-metallurgy (I/M) techniques. It is found that P/M Al-Li alloys containing 0.2 pct Zr are inherently superplastically formable without the need for extensive thermomechanical processing. I/M Al-Li alloys containing Zr are also superplastically formable. The mechanical properties of the superplastically formed and solution-treated-and-aged alloys are comparable to those of solution-treated-and-aged alloys before superplastic forming. 6 references

    Increased job opportunities in health professions make recruitment of students imperative. Effective recruitment requires a knowledge of what students value when making career decisions. This study of dietetic (n = 514) and other college students (n = 352) showed that achievement and economic security were the most important factors in their career selection regardless of major or race. Dietetic majors rated achievement, economic security, ability utilization, personal development, altruism, and working conditions significantly higher than did nondietetic students (p values important to students in this study are attainable through careers in dietetics and other allied health professions. The results of this study should be examined further with a larger sample of allied health majors to assist educators in recruiting and providing career counseling to students.

    Owing to unprecedented mechanization, everything to do with petroleum supplies had a crucial role to play in World War II. In the wake of Operation Overlord, the battle grounds of Normandy saw technologies deployed on a huge scale. Logistics were a major problem whether fighting in the air or on the ground, with oil and fuel supplies a critical element. With no fuel, this gigantic military operation could never have been carried through, for with aircraft grounded and tanks grinding to a halt, all would soon have been lost. Accordingly, the Allies made bold logistical plans, which nevertheless had shortcomings calling for improvisation. The cross-Channel pipeline PLUTO, the impressive stream of road traffic known as the Red Ball Express, rapid repairs to the railroads, trains of barges on the Seine, DC-3s transporting oil and fuel, were all pieces in the jigsaw puzzle bringing supplies to Allied units on their way across Normandy in 1944.

    Studied were carried out on the Portevin-Le Chatelier (PLC) effect in binary, ternary and quaternary Al-Li alloys and in the commercial 8090 alloy. The correlation between the serration characteristic, the rolling degree and the straining orientation has been analysed. The fact that the presence of the Cu-containing precipitates intensifies the PLC effects suggests, that these are primarily related to the interactions between the dislocations and the semi-coherent T 1 (Al 2 CuLi) precipitates. The analysis of the PLC effect in Al-Li alloys shows that the serrations in the stress-strain curve exhibit a profound degree of anisotropy. Most pronounced PLC effects are observed along the rolling and transverse directions. (author)

  19. Retention and release of tritium in aluminum clad, Al-Li alloys

    1991-01-01

    Tritium retention in and release from aluminum clad, aluminum-lithium alloys is modeled from experimental and operational data developed during the thirty plus years of tritium production at the Savannah River Site. The model assumes that tritium atoms, formed by the 6 Li(n,α) 3 He reaction, are produced in solid solution in the Al-Li alloy. Because of the low solubility of hydrogen isotopes in aluminum alloys, the irradiated Al-Li rapidly becomes supersaturated in tritium. Newly produced tritium atoms are trapped by lithium atoms to form a lithium tritide. The effective tritium pressure required for trap or tritide stability is the equilibrium decomposition pressure of tritium over a lithium tritide-aluminum mixture. The temperature dependence of tritium release is determined by the permeability of the cladding to tritium and the local equilibrium at the trap sites. This model is used to calculate tritium release from aluminum clad, aluminum-lithium alloys. 9 refs., 3 figs

    Structure, composition, properties combination of specimens and components, a number of technological parameters for production of advanced FML based on high-modulus Al-Li 1441 alloy (E 79 GPa) with reduced density (d 2.6 g/m3) and optimized adhesive prepreg reinforced with high-strength high-modulus VMP glass fibres are described. Service life 1441 alloy provides the possibility of manufacture of thin sheets (up to 0.3 mm), clad and unclad. Moreover, some experience on the usage of 1441 T1, T11 sheets and shapes in Be 200 and Be 103 aircraft was accumulated. The class of FML materials based on Al-Li alloy provide an 5% improvement in weight efficiency and stiffness of skin structures as compared with those made from FML with conventional Al-Cu-Mg (2024T3 a.o.) and Al-Zn-Mg-Cu (7475T76 a.o.) alloys.

    The aerospace industry is considering the use of low density, superplastically formable (SPF) materials, such as Al-Li alloys in cryogenic tankage. SPF modifications of alloys 8090, 2090, and 2090+In were tested for strength and Kahn tear toughness. The results were compared to those of similar tests of 2219-T87, an alloy currently used in cryogenic tankage, and 2090-T81, a recently studied Al-Li alloy with exceptional cryogenic properties (1-9). With decreasing temperature, all materials showed an increase in strength, while most materials showed an increase in elongation and decrease in Kahn toughness. The indium addition to 2090 increased alloy strength, but did not improve the strength-toughness combination. The fracture mode was predominantly intergranular along small, recrystallized grains, with some transgranular fracture, some ductile rupture, and some delamination on large, unrecrystallized grains.

  3. Radical heterosexuality: Straight teacher activism in schools : Does ally-led activism work?

    Here, I explore the efficacy of straight teacher allies, the importance of understanding straight privilege, and the significance of radical heterosexuality for straight people doing LGBTQ activism. Relying on queer theory and decolonizing/Indigenous queer theory, I argue that it is necessary for straight teachers to acknowledge their straight privilege in order to challenge homophobia's companions: heterosexism and heteronormativity. In addressing the latter two covert forms of oppression in schools, teachers and students could shift into deeper, more effective resistance measures.

    To describe the process and challenges from a project that aimed to develop processes, source new placements and place students primarily in the discipline of nursing, but also occupational therapy, physiotherapy, podiatry, social work, and speech therapy. Clinical experience in health facilities is an essential element of health professional education, yet globally, there is a lack of clinical placements to meet demands. Educational providers are seeking placements in nontraditional facilities, yet little has been reported on the challenges in the process of procuring clinical placements. The project used a descriptive approach within a quality implementation framework. The project was guided by the quality implementation framework that included four critical steps: considerations of the host setting, structuring the implementation, supporting the implementation and improving future applications. A total of 115 new student placements were finalised across six health disciplines, including elderly care, nongovernment organisations and general practice. Sixty-two nursing students were placed in the new placements during the project. Challenges included communication, the time-consuming nature of the process and 'gatekeeping' blocks to obtaining placements. Recommendations included the importance of personal interaction in developing and maintaining relationships, and the need for clear communication processes and documentation. Potential areas for research are also given. There is great potential for growth in establishing new placements outside the traditional placement facilities for nursing and allied health and for expanding already existing nonhospital placements. Clinical professional experiences are essential to any nursing or allied health programme. There is an increasing demand for, and global lack of, clinical placements for nursing and allied health students. The results provide nursing and allied health educators and managers a framework for planning

There are a number of drivers for this, including the changing demographics of patients and health professionals, changing working patterns and mobility of the health workforce, evolving models of care, emerging evidence base, altering funding models, and the need to underpin health care service delivery with safety, effectiveness, patient centeredness, efficiency, equity, and timeliness. It is in this time of change that role extension within health disciplines is seen as an important tool to meet some of these challenges. Role extension is viewed as a skills escalator, where practitioners move up the skills escalator within the scope of their discipline, to advance it and then, with training, extend it. Within allied health, in some disciplines, advanced and extended scope of practice initiatives have mushroomed. Often these initiatives have been ad hoc, and opportunistically created in response to local needs and requirements. As these initiatives are local and context-dependent, to date there is very little uniformity or congruency between these initiatives. This has led to variability in implementation, lack of rigorous evaluations and, ultimately, poor long-term sustainability. In this paper, we reflect on a number of key issues, drawing on our own experiences in undertaking such initiatives, which need to be taken into account when considering advanced and extended scope of practice for allied health.Keywords: allied health, skill escalation, extended scope of practice, advanced scope of practice

    2018-02-01

    Racism is a "wicked" public health problem that fuels systemic health inequities between population groups in New Zealand, the United States and elsewhere. While literature has examined racism and its effects on health, the work describing how to intervene to address racism in public health is less developed. While the notion of raising awareness of racism through socio-political education is not new, given the way racism has morphed into new narratives in health institutional settings, it has become critical to support allies to make informing efforts to address racism as a fundamental cause of health inequities. In this paper, we make the case for anti-racism praxis as a tool to address inequities in public health, and focus on describing an anti-racism praxis framework to inform the training and support of allies. The limited work on anti-racism rarely articulates the unique challenges or needs of allies or targets of racism, but we seek to help fill that gap. Our anti-racism praxis for allies includes five core elements: reflexive relational praxis, structural power analysis, socio-political education, monitoring and evaluation and systems change approaches. We recognize that racism is a modifiable determinant of health and racial inequities can be eliminated with the necessary political will and a planned system change approach. Anti-racism praxis provides the tools to examine the interconnection and interdependence of cultural and institutional factors as a foundation for examining where and how to intervene to address racism.

    Full Text Available Prior species distribution models identified temperature as one of the most important environmental variables defining the present and future distribution of anadromous allis shad (Alosa alosa. The current study analysed effects of temperature on the recruitment-potential of allis shad by investigating growth and survival at 16, 20, 24 and 28 °C during a ten day rearing trial and by measuring mass-specific respiration. Highest growth in length was at 28 °C; growth at 16 °C was minimal. At the end of the rearing-period, no significant differences in survival between tested rearing-temperatures were found. Exposure to temperatures of 13 to 30 °C and subsequent measurement of mass-specific respiration revealed tolerance of temperatures up to 30 °C and a lower temperature limitation close to 16 °C. After acclimatization of larvae to temperatures ranging from 16−28 °C for 10 days, Q10-values of mass-specific respiration indicated a high adaptive capacity to increasing temperatures, but also the ability to adapt to temperatures as low as 16 °C. Our results indicate that the predicted temperature sensitivity of A. alosa cannot be explained by a direct physiological relationship. The obtained results can help to improve predictive modelling and the conservation of allis shad throughout its current distribution range.

    Full Text Available Upstream and downstream of supply chain enterprises often form a tactic vertical alliance to enhance their operational efficiency and maintain their competitive edges in the market. Hence, it is critical for an alliance to collaborate over their internal resources and resolve the profit conflicts among members, so that the functionality required by stakeholders can be fulfilled. As an effective solution, automated negotiation for the vertical allied enterprises team and stakeholder will sufficiently make use of emerging team advantages and significantly reduce the profit conflicts in teams with grouping decisions rather than unilateral decisions by some leader. In this paper, an automated negotiation model is designed to describe both the collaborative game process among the team members and the competitive negotiation process between the allied team and the stakeholder. Considering the co-competitiveness of the vertical allied team, the designed model helps the team members making decision for their own sake, and the team counter-offers for the ongoing negotiation are generated with non-cooperative game process, where the profit derived from negotiation result is distributed with Shapley value method according to contribution or importance contributed by each team member. Finally, a case study is given to testify the effectiveness of the designed model.

    There are a variety of resources to obtain health information, but few studies have examined if main and allied health professionals prefer different methods. The current study was to investigate their information-searching behaviours. A constructed questionnaire survey was conducted from January through April 2011 in nationwide regional hospitals of Taiwan. Questionnaires were mailed to main professionals (physicians and nurses) and allied professionals (pharmacists, physical therapists, technicians and others), with 6160 valid returns collected. Among all professional groups, the most commonly used resource for seeking health information was a Web portal, followed by colleague consultations and continuing education. Physicians more often accessed Internet-based professional resources (online databases, electronic journals and electronic books) than the other groups (P < 0.05). In contrast, physical therapists more often accessed printed resources (printed journals and textbooks) than the other specialists (P < 0.05). And nurses, physical therapists and technicians more often asked colleagues and used continuing education than the other groups (P < 0.01). The most commonly used online database was Micromedex for pharmacists and MEDLINE for physicians, technicians and physical therapists. Nurses more often accessed Chinese-language databases rather than English-language databases (P < 0.001). This national survey depicts the information-searching pattern of various health professionals. There were significant differences between and within main and allied health professionals in their information searching. The data provide clinical implications for strategies to promote the accessing of evidence-based information. © 2012 John Wiley & Sons Ltd.

    Wellness approaches are not routine in childhood disability services, despite theoretical and empirical support and an increasing demand for them from health consumers and disability activists. We aimed to investigate how health professionals define or understand wellness and its practice in the context of childhood disability. A qualitative, interpretive approach was taken. Semi-structured interviews were conducted with 23 health professionals (allied health therapists and managers) providing early intervention and ongoing therapy within four Australian childhood health and disability services. Years of experience providing services to children with disabilities and their families ranged from 6 months to 30 years (M=9.41, SD=9.04). The data revealed a noteworthy impediment to incorporating wellness into practice - the difficulties in the allied health professionals reaching consensus in defining wellness. There appeared to be distinct differences between the four services, while there appeared to be no appreciable difference based on the individual professional's years of experience or allied health discipline. The effect of organisational culture should be considered in efforts to embed wellness in childhood health and disability services in order to address client well-being, empowerment, choice, independence and rights to meaningful and productive lives. © 2011 Informa UK, Ltd.

    It is always difficult to construct coherent classification systems for plant lineages having diverse morphological characters. The genus Dendrobium, one of the largest genera in the Orchidaceae, includes ∼1100 species, and enormous morphological diversification has hindered the establishment of consistent classification systems covering all major groups of this genus. Given the particular importance of species in Dendrobium section Dendrobium and allied groups as floriculture and crude drug genetic resources, there is an urgent need to establish a stable classification system. To clarify phylogenetic relationships in Dendrobium section Dendrobium and allied groups, we analysed the macromolecular characters of the group. Phylogenetic analyses of 210 taxa of Dendrobium were conducted on DNA sequences of internal transcribed spacer (ITS) regions of 18S–26S nuclear ribosomal DNA and the maturase-coding gene (matK) located in an intron of the plastid gene trnK using maximum parsimony and Bayesian methods. The parsimony and Bayesian analyses revealed 13 distinct clades in the group comprising section Dendrobium and its allied groups. Results also showed paraphyly or polyphyly of sections Amblyanthus, Aporum, Breviflores, Calcarifera, Crumenata, Dendrobium, Densiflora, Distichophyllae, Dolichocentrum, Holochrysa, Oxyglossum and Pedilonum. On the other hand, the monophyly of section Stachyobium was well supported. It was found that many of the morphological characters that have been believed to reflect phylogenetic relationships are, in fact, the result of convergence. As such, many of the sections that have been recognized up to this point were found to not be monophyletic, so recircumscription of sections is required. PMID:25107672

    Allied health manpower in developing countries should be able to serve the specific needs of these countries in solving malnutrition, diarrheal disease, and other health problems. Disease patterns tend to evolve in stages with each stage requiring a special type of health manpower: 1) the 1st stage where infectious diseases are linked to poverty, malnutrition, and poor personal hygiene for which personnel trained to improve health through providing safe water supplies, improving sanitation, and immunizing the population are needed; 2) in the 2nd stages, diseases such as cancer, arthritis, and cardiac diseases exist, requiring extensive technology such as is available in the US; and 3) the 3rd stage relates to an awareness of health hazards (caused by the environment, by the lifestyle dysfunctions of the society, and an emphasis on health promotion) and implies a responsibility for one's own health by the individual; this is a difficult stage to apply to developing countries since the ability to bring about change assumes literacy on the part of the population which is not always the case. Since most developing countries need to cause change in the 1st stage, more public health personnel such as sanitarians and generalist workers are needed. Training of these personnel should include on-the-job education; traditionally trained US allied health professionals are not always equipped to deal with health problems in developing countries. Health educators should look to the lessons learned by the US in the allied health movement: 1) the system of control that national membership organizations have over schooling and the job environment has contributed to an increased cost of health care delivery, unnecessary prolonged curricula, overspecialization, extreme protectionism for membership, and inappropriate fractionalization of health care delivery; 2) the emphasis on prolonged curricula sometimes causes the student to lose sight of the supposed direct relationship between

    Allied health comprises multiple professional groups including dietetics, medical radiation practitioners, occupational therapists, optometrists and psychologists. Different to medical and nursing, Allied health are often organized in discipline specific departments and allocate budgets within these to provide services to a range of clinical areas. Little is known of how managers of allied health go about allocating these resources, the factors they consider when making these decisions, and the sources of information they rely upon. The purpose of this study was to identify the key factors that allied health consider when making resource allocation decisions and the sources of information they are based upon. Four forums were conducted each consisting of case studies, a large group discussion and two hypothetical scenarios to elicit data. A thematic content analysis commenced during post-forum discussions of key factors by forum facilitators. These factors were then presented to an expert working party for further discussion and refinement. Transcripts were generated of all data recordings and a detailed thematic analysis was undertaken by one author to ensure coded data matched the initial thematic analysis. Twelve factors affecting the decision-making of allied health managers and clinicians were identified. One of these factors was disendorsed by the expert working party. The 11 remaining factors can be considered to be key decision-making principles that should be consistently applied to resource allocation. These principles were clustered into three overarching themes of readiness, impact and appropriateness. Understanding these principles now means further research can be completed to more effectively integrate research evidence into health policy and service delivery, create partnerships among policy-makers, managers, service providers and researchers, and to provide support to answer difficult questions that policy-makers, managers and service providers

Contribution of archaeological analogs to the estimation of average corrosion rates and long term corrosion mechanisms of low carbon steel in soil; Apport des analogues archeologiques a l'estimation des vitesses moyennes et a l'etude des mecanismes de corrosion a tres long terme des aciers non allies dans les sols

    In the context of the French nuclear waste storage, a multi-barriers disposal is envisaged. Wastes could be put in metallic overpacks disposed in a clay soil. As these overpacks could be made of low carbon steel, it is important to understand the corrosion behaviour of this material in soil during period of several centuries. Indeed, it is necessary to consolidate the empirical data by a phenomenological approach. This includes laboratory experiments and modelling of the phenomenon which have to be validated and completed by the study of archaeological artefacts. This was the aim of this PhD-work. To this purpose, an analytical protocol has been elaborated: about forty archaeological artefacts coming from five dated sites (2. to 16. centuries) have been studied on cross section in order to observe on the same sample all the constituents of the system: metallic substrate/corrosion products/environment. The corrosion products are divided into two zones: the Dense Product Layer (DPL) in contact with the metal, and the Transformed Medium (TM) which are the corrosion products formed around soil minerals (quartz grains). The metallic substrate has been studied by the classical methods of materials science (optical and scanning electron microscope, energy and wavelength dispersive spectroscopies). It has been verified that despite their heterogeneity of structure and composition, they are all hypo-eutectoids steels that can contain phosphorous until 0.5 wt%. The corrosion products have been analysed by local structural analytical methods as micro-diffraction under synchrotron radiation ({mu}XRD) and Raman micro-spectroscopy. These two complementary techniques and also the elemental composition analysis conducted to the characterisation of the corrosion forms. On the majority of the samples coming from four sites, the DPL are constituted by goethite including marbles of magnetite/maghemite. On the artefacts from the fifth site, a particular corrosion form has been identified. This corrosion form, constituted among others by a siderite layer is due to a particular environment: waterlogged soil containing wood. In the whole, analyses conducted in the TM show that it is composed of goethite badly crystallized in comparison with those of the DPL. Moreover, in this zone, the average elemental iron amount decreases progressively from the metal to the soil in which it stabilizes. In order to know the behaviour of the identified phases in soil water, some thermodynamic data have been involved to calculate their solubility in function of pH, potential and various water composition. The first conclusion concerns the influence of the composition and the structure of the material which is not important for the corrosion behaviour. From the results, some hypothesis have been formulated on the long term corrosion mechanisms of hypo-eutectoids steels in the considered environment. The role of the cracks formed in the DPL during the burial was evidenced. Moreover, these corrosion products undertake a dissolution in the soil water and a reprecipitation, explaining the progressive decrease of the iron amount in the TM. Lastly, some average corrosion rates have been measured with the help of the analytical and thermodynamic results: they do not exceed 4 {mu}m/year. (author)

    With a view to their use in the exchangers of nuclear reactors of the graphite-gas or heavy water-gas types, the behaviour of chromium-aluminium steels containing up to 7 per cent chromium and 1.5 per cent aluminium has been studied in the presence of high-pressure carbon dioxide at temperatures of between 400 and 700 deg. C. The two most interesting grades of steel (2 per cent Cr - 0.35 per cent Al - 0.35 per cent Mo and 7 per cent Cr - 1.5 per cent Al - 0.6 per cent Si) are still compatible with carbon dioxide up to 550 and 600 deg. C respectively. A hot dip aluminised coating considerably increases resistance to oxidation of the first grade and should make possible its use up to temperatures of at least 600 deg. C. (authors) [French] Dans l'optique de leur emploi dans les echangeurs de reacteurs nucleaires des filieres graphite-gaz ou eau lourde-gaz, le comportement en presence de gaz carbonique sous pression d'aciers au chrome-aluminium, contenant jusqu'a 7 pour cent de chrome et 1,5 pour cent d'aluminium a ete etudie entre 400 et 700 deg. C. Les deux nuances les plus interessantes (2 pour cent Cr - 0,35 pour cent Al - 0,35 pour cent Mo et 7 pour cent Cr - 1,5 pour cent Al - 0,6 pour cent Si) restent compatibles avec le gaz carbonique jusqu'a 550 et 600 deg. C respectivement. Un revetement d'aluminium, effectue par immersion dans un bain fondu, ameliore notablement la resistance a l'oxydation de la premiere et doit permettre son empioi jusqu'a 600 deg.

    These tests were carried out with a view to observing the results obtained by using electrolytic polishing for the decontamination operations. The experimental equipment consists essentially of a current rectifier and adjuster, and of an electrolytic cell fitted with an automatic system for thermal regulation and agitation. The samples made of type NS 22 S stainless steel are contaminated with an active solution of fission products. The activity of the discs is measured before and after each treatment using a bell counter. For each electrolyte, the parameters studied are: - the time, - the reactant concentration, - the temperature, - the current density, - the corrosion. Taking into account the necessity of transforming as little as possible the surface of the part to be treated, the best results are generally obtained using intermediate concentrations of the reactant, low temperatures, and high current densities. (authors) [French] Ces essais ont ete effectues dans le but d'observer les resultats obtenus en utilisant le procede de polissage electrolytique pour les operations de decontamination. Le dispositif experimental consiste essentiellement en un redresseur-variateur de courant et en une cellule electrolytique munie d'un systeme automatique de regulation thermique et d'agitation. Les echantillons en acier inoxydable du type NS 22 S sont contamines par une solution active de produits de fission. L'activite des plaquettes est mesuree avant et apres chaque traitement au moyen d'un compteur cloche. Pour chaque electrolyte, les parametres etudies sont: - le temps, - la concentration du reactif, - la temperature, - la densite de courant, - la corrosion. En tenant compte de la necessite de transformer au minimum l'etat de surface de la piece a traiter, les resultats les meilleurs sont generalement obtenus pour des concentrations moyennes de reactif, des temperatures basses et des densites de courant elevees.

    Allied health professionals (AHPs) report positive attitudes to using research evidence in clinical practice, yet often lack time, confidence and skills to use, participate in and conduct research. A range of multifaceted strategies including education, mentoring and guidance have been implemented to increase AHPs' use of and participation in research. Emerging evidence suggests that knowledge brokering activities have the potential to support research engagement, but it is not clear which knowledge brokering strategies are most effective and in what contexts they work best to support and maintain clinicians' research engagement. This protocol describes an exploratory concurrent mixed methods study that is designed to understand how allied health research fellows use knowledge brokering strategies within tailored evidence-based interventions, to facilitate research engagement by allied health clinicians. Simultaneously, a realist approach will guide a systematic process evaluation of the research fellows' pattern of use of knowledge brokering strategies within each case study to build a programme theory explaining which knowledge brokering strategies work best, in what contexts and why. Learning and behavioural theories will inform this critical explanation. An explanation of how locally tailored evidence-based interventions improve AHPs use of, participation in and leadership of research projects will be summarised and shared with all participating clinicians and within each case study. It is expected that local recommendations will be developed and shared with medical and nursing professionals in and beyond the health service, to facilitate building research capacity in a systematic and effective way. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To explore the perceptions and experiences of nurse and allied health professional consultants and key stakeholders. Nurse and allied health professional consultants' roles were introduced in the United Kingdom in 1999 with defined role criteria and a remit to improve patient outcomes. Although these roles have now existed for over a decade, there is a lack of research as to whether these roles have achieved their intended impact on clinical care. Through an exploration of the experiences of consultant nurses and allied health professionals and key stakeholders who work with these practitioners, a greater understanding of the consultant role can be achieved. Qualitative. A purposive sample of seven non-medical consultants (five nurses, one physiotherapist and a pharmacist) and eight stakeholders took part in focus group interviews. Each focus group was audio-taped and lasted between 1.5-2 hours. Content analysis was used to interpret the data. Four main themes were identified: (1) Role interpretation--core features include clinical practice, leadership, education and research. Debate surrounded the need to incorporate managerial responsibilities into the role. (2) Role implementation required political skills and emotional intelligence. (3) Role impact especially on clinical practice was a major priority for both groups. (4) Challenges included lack of organisational and administrative support. There was consensus amongst the two groups regarding the value of the role, key role functions and skills and the emerging impact on clinical practice. Both groups were able to identify the clinical impact of the role including helping patients manage chronic pain, reducing the need for follow-up appointments and managing emergency admissions. To capture the clinical diversity of the roles, a variety of evaluation strategies should be implemented. © 2011 Blackwell Publishing Ltd.

    Nonlicensed allied health workers are becoming increasingly important in collaborative team care, yet we know little about their experiences while filling these roles. To explore their perceptions of working as health coaches in a chronic-disease collaborative team, the teamlet model, we conducted a qualitative study to understand the nature and dynamics of this emerging role. During semistructured interviews, 11 health coaches reflected on their yearlong experience in the teamlet model at an urban underserved primary care clinic. Investigators conducted a thematic analysis of transcriptions of the interviews using a grounded theory process. Four themes emerged: 1) health-coach roles and responsibilities included acting as a patient liaison between visits, providing patient education and cultural brokering during medical visits, and helping patients navigate the health care system; 2) communication and relationships in the teamlet model of care were defined by a triad of the patient, health coach, and resident physician; 3) interest in the teamlet model was influenced by allied health workers' prior education and health care roles; and 4) factors influencing the effectiveness of the model were related to clinical and administrative time pressures and competing demands of other work responsibilities. Nonlicensed allied health workers participating in collaborative teams have an important role in liaising between patients and their primary care physicians, advocating for patients through cultural brokering, and helping patients navigate the health care system. To maximize their job satisfaction, their selection should involve strong consideration of motivation to participate in these expanded roles, and protected time must be provided for them to carry out their responsibilities and optimize their effectiveness.

    Full Text Available Introduction Until the very recent time majority of AYUSH graduates were limited to their own field of study with few exceptions in to the field of public health and allied areas. The reasons could be lack of awareness, unavailability of suitable job opportunity or a sense of insecurity in a relatively new and offbeat domain of work. However more recently, there has been a paradigm shift; with increase in information access, awareness of job opportunities and a great degree of professional and personal satisfaction. This has led to a huge rush of these graduates in to the field of public health and allied areas. Objective ToexplorepublichealthandalliedcareerchoicesforAYUSHgraduateswithspecialreferencetothe scopes and opportunities in each of these fields. Methodology Review based study. Information was obtained by systematic search process using internet based Google, Google Scholar search engines. Discussion The results obtained were pertinent to the domain of public health and allied careers including Public health and related areas such as; Health and Hospital Management, Health Policy, Health Economics, Heath Care Financing, Epidemiology, Medical Sociology, Clinical Research, Pharmaceutical Management etc. it is observed that the placement and job opportunities are much more because of the rapid expansion of health care industry in India with endeavors from public and private stakeholders. There has been a multimillion dollars investment by various national and international donor agencies, pharmaceutical sector, central and state governments and the development partners. Conclusion AYUSH graduates can definitely find this field interesting as well as challenging and job opportunities may not be a problem for the right one.

    The management of older persons with cancer has become a major public health concern in developed countries because of the aging of the population and the steady increase in cancer incidence with advancing age. Nurses and allied health care professionals are challenged to address the needs of this growing population. The International Society of Geriatric Oncology (SIOG) Nursing and Allied Health (NAH) Interest Group described key issues that nurses and allied health care professionals face when caring for older persons with cancer. The domains of the Geriatric Assessment (GA) are used as a guiding framework. The following geriatric domains are described: demographic data and social support, functional status, cognition, mental health, nutritional status, fatigue, comorbidities, polypharmacy, and other geriatric syndromes (e.g. falls, delirium). In addition to these geriatric domains, quality of life (QoL) is described based on the overall importance in this particular population. Advice for integration of assessment of these geriatric domains into daily oncology practice is made. Research has mainly focused on the role of treating physicians but the involvement of nurses and allied health care professionals is crucial in the care of older persons with cancer through the GA process. The ability of nurses and allied health care professionals to perform this assessment requires specialized training and education beyond standard oncology knowledge. Copyright © 2016 Elsevier Inc.

Research suggests that considerable differences between and within AH disciplines exist, which require different approaches in order to influence practice behavior. It is therefore important to develop a better understanding of what influences individual AH practitioners’ adoption of evidence into daily practice.Objective: This systematic review aims to examine the individual characteristics of AH practitioners which determine their uptake of evidence into practice.Methods: Studies which examined individual factors or variables that influence research evidence use by any AH practitioner were included in the review. The methodological quality of the included papers was assessed using the Quality Assessment and Validity Tool for Cross-sectional Studies. A narrative summary of the findings was presented.Results: Six studies were included and the methodological quality scores indicated that two were weak and the remainder had moderate–weak quality. The review demonstrated that factors such as educational degree or academic qualification, involvement in research or EBP-related activities, and practitioners’ perceptions, attitudes and beliefs about research and EBP are significant predictors of self-reported research evidence use in AH. The effect of other factors such as professional characteristics, clinical setting/work environment, information-seeking behavior and sociodemographic variables are less clear. Whether there is an interaction effect between evidence-uptake factors has not been tested.Conclusion: Improving the research knowledge of clinicians and overcoming negative attitudes toward EBP have the potential to move AH

    The anadromous allis shad Alosa alosa has suffered dramatic population declines throughout Europe and is currently considered as endangered throughout its entire distribution range. In order to reestablish allis shad in the River Rhine, which formerly housed one of the largest and most important populations, an EU-LIFE Project 'The re-introduction of allis shad in the Rhine system' was started in 2007. In course of the LIFE+ Projects, allis shad larvae bred from genitor fish of the Gironde-Garonne-Dordogne population in France were reared in a pilot ex situ stock plant pilot facility in Aßlar, Germany. At an age of 1-2 months, about 100% of these fish developed approximately 0.5- to 0.8-cm large, fluid-filled, transparent cysts in conjunction with the upper jaw. The performed microbiological, virological, parasitological and histological examinations did not detect any infectious agents. Possible causative agents are discussed with regard to environmental factors and the nutrition of larvae. In conclusion, the observed malformations are considered a sign for a severe health problem and therefore a risk for the successful breeding of allis shad in aquaculture. © 2016 John Wiley & Sons Ltd.

  16. Doing what we can, but knowing our place: Being an ally to promote consumer leadership in mental health.

    Consumer participation in all aspects of mental health services is clearly articulated as an expectation of contemporary mental health policy. Consumer leadership has been demonstrated to be beneficial to mental health services. Barriers to implementation have limited the realization of this goal. In this discursive paper, we argue that non-consumers who support consumer partnerships and leadership (known as 'allies') have an important role to play in facilitating and supporting consumers in leadership roles. Allies currently have more potential to influence resource allocation, and might be viewed more credibly by their peers than consumer leaders themselves. We call for allies to ensure their role is one of support and facilitation (doing what they can), rather than directing the content or speaking on behalf of the consumer movement (knowing their place). In the present study, we address the importance of allies for the consumer movement. It proposes some 'rules of engagement' to ensure that allies do not intentionally or otherwise encroach on consumer knowledge and expertise, so that they maintain the important position of supporting consumers and facilitating the valuing and use of consumer knowledge, expertise, and ultimately, leadership. © 2017 Australian College of Mental Health Nurses Inc.

    A possible modification to the well known Clemmow- Mullaly-Allis diagram is analysed taking into account the radiation pressure force due to a large-amplitude electromagnetic field E in magnetoplasmas. We restrict ourselves here to the propagations parallel (the right and left-hand circularly polarized waves) and/or perpendicular (the ordinary and extraordinary modes) to the static magnetic field Bsub(o). We analyse electromagnetic waves incident normally on a semi-infinite uniform plasma, on which Bsub(o) is applied parallel and/or perpendicular to the surface. Considerations are limited to a cold collisionless plasma where the incident waves are evanescent. Simple expressions are obtained for the cut-off conditions of the waves except the extraordinary mode. In the latter case, the cut-off condition is calculated numerically solving an integral equation. The results are demonstrated in the usual Clemmow-Mullaly-Allis diagram for the various values of b=2Esub(i) 2 e 2 /mω 2 kappaTsub(e') where Esub(i) and ω are, respectively, the amplitude and the angular frequency of the incident wave. The cut-off lines are shown to move towards the higher densities with increasing b. (auth.)

    Full Text Available After the collapse of the bipolar international order, NATO has been focused on its desire to eradicate Cold War divisions and to build good relations with Russia. However, the security environment, especially in Europe, is still dramatically changing. The NATO Warsaw Summit was focused especially on NATO’s deteriorated relations with Russia that affect Europe’s security. At the same time, it looked at bolstering deterrence and defence due to many concerns coming from eastern European allies about Russia’s new attitude in international relations. The Allies agreed that a dialogue with Russia rebuilding mutual trust needs to start. In the times when Europe faces major crisis from its southern and south-eastern neighbourhood - Western Balkan countries, Syria, Libya and Iraq - and other threats, such as terrorism, coming from the so-called Islamic State, causing migration crises, it is necessary to calm down relations with Russia. The article brings out the main purpose of NATO in a transformed world, with the accent on Europe, that is constantly developing new security conditions while tackling new challenges and threats.

    Competency-based education in health care requires rigorous standards to ensure professional proficiency. Demonstrating competency in hands-on laboratories calls for effective preparation, knowledge, and experience, all of which can be difficult to achieve using traditional teaching methods. Virtual laboratories are an alternative, cost-effective approach to providing students with sufficient preparatory information. Research on the use of virtual labs in allied health education is limited. The current study investigated the benefits, challenges, and perceived impact of a virtual lab in an allied health program. The sample consisted of 64 students (55 females, 9 males) enrolled in a university medical laboratory science program. A convergent mixed-methods approach (Likert survey, open-ended questions, think-aloud protocol data) revealed that students had positive attitudes towards visual learning, authenticity, learner control, organization, and scaffolding afforded by the virtual lab. Challenges reported included navigational difficulties, an absence of control over content selection, and lack of understanding for certain concepts. Over 90% of students agreed that the virtual lab helped them prepare for hands-on laboratory sessions and that they would use this format of instruction again. Overall, 84% of the students agreed that the virtual lab helped them to achieve greater success in learning.

  20. Strategies for teaching pathology to graduate students and allied health professionals.

    2005-02-01

    Pathology is an essential course for many students in the biomedical sciences and allied health professions. These students learn the language of pathology and medicine, develop an appreciation for mechanisms of disease, and understand the close relationship between basic research and clinical medicine. We have developed 3 pathology courses to meet the needs of our undergraduates, graduate students, and allied health professionals. Through experience, we have settled on an approach to teaching pathology that takes into account the diverse educational backgrounds of these students. Educational resources such as assigned reading, online homework, lectures, and review sessions are carefully balanced to adjust course difficulty. Common features of our pathology curricula include a web-based computer laboratory and review sessions on the basis of selected pathology images and open-ended study questions. Lectures, computer-guided homework, and review sessions provide the core educational content for undergraduates. Graduate students, using the same computer program and review material, rely more heavily on assigned reading for core educational content. Our experience adapting a pathology curriculum to the needs of divergent groups of students suggests a general strategy for monitoring course difficulty. We hypothesize that course difficulty is proportional to the information density of specific learning resources (eg, lecture or textbook) multiplied by the weight of those learning resources placed on examinations. This formula allows educators to match the difficulty of a course with the educational needs of students, and provides a useful tool for longitudinal studies of curriculum reform.

    Delamination fracture has limited the use of lightweight Al-Li alloys. In the present study, electron backscattered diffraction (EBSD) methods were used to characterize crack paths in Al-Li alloy C458 (2099). Secondary delamination cracks in fracture toughness samples showed a pronounced tendency for fracture between grain variants of the same deformation texture component. These results were analyzed by EBSD mapping methods and simulated with finite element analyses. Simulation procedures include a description of material anisotropy, local grain orientations, and fracture utilizing crystal plasticity and cohesive zone elements. Taylor factors computed for each grain orientation subjected to normal and shear stresses indicated that grain pairs with the largest Taylor factor differences were adjacent to boundaries that failed by delamination. Examination of matching delamination fracture surface pairs revealed pronounced slip bands in only one of the grains bordering the delamination. These results, along with EBSD studies, plasticity simulations, and Auger electron spectroscopy observations support a hypothesis that delamination fracture occurs due to poor slip accommodation along boundaries between grains with greatly differing plastic response.

  2. Estimation of dislocation concentration in plastically deformed Al-Li based alloy by positron annihilation

    Measurements of positron annihilation mean lifetime τ have been performed on eight different specimens of Al-Li based alloy plastically deformed at room temperature up to 40% thickness reduction. This measurement shows clearly positron trapping by dislocations. The positron lifetime τ exhibits a saturation for deformations larger than (15%) thickness reduction. The fitted lifetime varies from (183±2 ps) for annealed sample to (205±2 ps) for the dislocation saturated value. Using a trapping model, the data yield the values of μ=3.83x10 -8 cm 3 s -1 for the specific trapping rate and σ=3.58x10 -15 cm 2 for the trapping cross section, some what lower than those for plastically deformed Al single crystals. The value obtained for Δτ, the increase in lifetime of positrons trapped at dislocations in plastically deformed Al-Li based alloy sample over annihilation in the annealed sample, is 22 ps. This is about 40% of the lifetime increase for the case of positrons trapped at dislocations in plastically deformed Al single crystals. Dislocation densities at different thickness reduction have been estimated. (author)

    Objective: To determine the frequency and determinants of low birth weight (LBW) babies in the allied hospitals of Rawalpindi Medical College (RMC). Methodology: In this cross sectional survey, a total of 120 mothers coming to Allied Hospitals of RMC, having babies up to the age of 6 months were enrolled by purposive sampling. Data were collected by a semi structured questionnaire, which asked information from mothers regarding their education, socioeconomic class and occupation. Questions were also asked about last child birth such as frequency of antenatal visits during that pregnancy, risk factors during pregnancy like hypertension, pallor, duration of pregnancy at time of delivery. Data were analyzed using SPSS v. 21. Results: Frequency of LBW babies was found to be 27.4%. 10.83% mothers were educated up to graduate and above and 32% belonged to low socioeconomic class. 11.6% mothers had taken no antenatal visits. 31.6% mothers had hypertension, which was found to be a major factor determining LBW (p 0.00001). 8.3% children born were premature. Prematurity was significantly related with LBW (p 0.0001). Conclusion: LBW was high in low socioeconomic class and was significantly related with premature births and hypertension in mother during pregnancy. (author)

  4. Building alliances in unlikely places: progressive allies and the Tobacco Institute's coalition strategy on cigarette excise taxes.

    2009-07-01

    The tobacco industry often utilizes third parties to advance its policy agenda. One such utilization occurred when the industry identified organized labor and progressive groups as potential allies whose advocacy could undermine public support for excise tax increases. To attract such collaboration, the industry framed the issue as one of tax fairness, creating a labor management committee to provide distance from tobacco companies and furthering progressive allies' interests through financial and logistical support. Internal industry documents indicate that this strategic use of ideas, institutions, and interests facilitated the recruitment of leading progressive organizations as allies. By placing excise taxes within a strategic policy nexus that promotes mutual public interest goals, public health advocates may use a similar strategy in forging their own excise tax coalitions.

    Uneven distribution of the medical workforce is globally recognised, with widespread rural health workforce shortages. There has been substantial research on factors affecting recruitment and retention of rural doctors, but little has been done to establish the motives and conditions that encourage allied health professionals to practice rurally. This study aims to identify aspects of recruitment and retention of rural allied health professionals using qualitative methodology. Six focus groups were conducted across rural NSW and analysed thematically using a grounded theory approach. The thirty allied health professionals participating in the focus groups were purposively sampled to represent a range of geographic locations, allied health professions, gender, age, and public or private work sectors. Five major themes emerged: personal factors; workload and type of work; continuing professional development (CPD); the impact of management; and career progression. 'Pull factors' favouring rural practice included: attraction to rural lifestyle; married or having family in the area; low cost of living; rural origin; personal engagement in the community; advanced work roles; a broad variety of challenging clinical work; and making a difference. 'Push factors' discouraging rural practice included: lack of employment opportunities for spouses; perceived inadequate quality of secondary schools; age related issues (retirement, desire for younger peer social interaction, and intention to travel); limited opportunity for career advancement; unmanageable workloads; and inadequate access to CPD. Having competent clinical managers mitigated the general frustration with health service management related to inappropriate service models and insufficient or inequitably distributed resources. Failure to fill vacant positions was of particular concern and frustration with the lack of CPD access was strongly represented by informants. While personal factors affecting recruitment and

    Knowledge translation (KT) aims to close the research-practice gap in order to realize and maximize the benefits of research within the practice setting. Previous studies have investigated KT strategies in nursing and medicine; however, the present study is the first systematic review of the effectiveness of a variety of KT interventions in five allied health disciplines: dietetics, occupational therapy, pharmacy, physiotherapy, and speech-language pathology. A health research librarian developed and implemented search strategies in eight electronic databases (MEDLINE, CINAHL, ERIC, PASCAL, EMBASE, IPA, Scopus, CENTRAL) using language (English) and date restrictions (1985 to March 2010). Other relevant sources were manually searched. Two reviewers independently screened the titles and abstracts, reviewed full-text articles, performed data extraction, and performed quality assessment. Within each profession, evidence tables were created, grouping and analyzing data by research design, KT strategy, targeted behaviour, and primary outcome. The published descriptions of the KT interventions were compared to the Workgroup for Intervention Development and Evaluation Research (WIDER) Recommendations to Improve the Reporting of the Content of Behaviour Change Interventions. A total of 2,638 articles were located and the titles and abstracts were screened. Of those, 1,172 full-text articles were reviewed and subsequently 32 studies were included in the systematic review. A variety of single (n = 15) and multiple (n = 17) KT interventions were identified, with educational meetings being the predominant KT strategy (n = 11). The majority of primary outcomes were identified as professional/process outcomes (n = 25); however, patient outcomes (n = 4), economic outcomes (n = 2), and multiple primary outcomes (n = 1) were also represented. Generally, the studies were of low methodological quality. Outcome reporting bias was common and precluded clear determination of intervention

    Universities Allied for Essential Medicines organized its first Neglected Diseases and Innovation Symposium to address expanding roles of public sector research institutions in innovation in research and development of biomedical technologies for treatment of diseases, particularly neglected tropical diseases. Universities and other public research institutions are increasingly integrated into the pharmaceutical innovation system. Academic entities now routinely undertake robust high-throughput screening and medicinal chemistry research programs to identify lead compounds for small molecule drugs and novel drug targets. Furthermore, product development partnerships are emerging between academic institutions, non-profit entities, and biotechnology and pharmaceutical companies to create diagnostics, therapies, and vaccines for diseases of the poor. With not for profit mission statements, open access publishing standards, open source platforms for data sharing and collaboration, and a shift in focus to more translational research, universities and other public research institutions are well-placed to accelerate development of medical technologies, particularly for neglected tropical diseases.

  13. Dislocation dynamics in Al-Li alloys: mean jump distance and activation length of moving dislocations

    De Hosson, J.Th.M.; Huis Int Veld, A.

    1984-01-01

    It is pointed out that aluminum-lithium based alloys offer considerable promise for structural applications, especially in the aerospace industry. This promise is related to the potential for high strength in combination with a density which is lower than that found in conventional aluminum alloys. In addition, the modulus of elasticity is higher than corresponding values in conventional aluminum alloys. A nuclear magnetic resonance study of the mechanism of dislocation motion in Al-2.2 wt pct Li is reported. Information about the effective mean jump distance of mobile dislocations is provided by in situ nuclear spin relaxation measurements. The activation length of mobile dislocations has been obtained from strain-rate change experiments on Al-2.2 wt pct Li. The considered study shows that pulsed nuclear magnetic resonance is a complementary new technique for the study of moving dislocations in Al-Li alloys. 28 references

    2009-01-01

    This paper discusses how psychoanalytic ideas were brought to bear in the Allied struggle against the Third Reich and explores some of the claims that were made about this endeavour. It shows how a variety of studies of Fascist psychopathology, centered on the concept of superego, were mobilized in military intelligence, postwar planning and policy recommendations for "denazification." Freud's ideas were sometimes championed by particular army doctors and government planners; at other times they were combined with, or displaced by, competing, psychiatric and psychological forms of treatment and diverse studies of the Fascist "personality." This is illustrated through a discussion of the treatment and interpretation of the deputy leader of the Nazi Party, Rudolf Hess, after his arrival in Britain in 1941.

    As scholarship and research in multicultural psychology evolves to a multilayered and complex discipline, increased attention to the role of larger structural forces of privilege has come to the forefront. Intersectionality of sociopolitical identities and the role those with privilege have in confronting oppression becomes a critical component of multicultural education. The edited volume, Deconstructing Privilege: Teaching and Learning as Allies in the Classroom (Case, 2013) provides concrete guidance and examples for educators seeking to enhance their approach to teaching privilege as a necessary mirror of oppression. This review highlights strengths of the book for educators in psychology and suggests recommendations for more complex discussion of the integration of privilege within the framework of structural oppression.

    Darters (Percidae: Etheostomatinae), a species-rich group of North American freshwater fishes, vary in the presence of a premaxillary fraenum, a strip of skin that connects the premaxillary bones to the snout, and it is hypothesized that this trait is a trophic adaptation to particular substrata. Ancestral state reconstructions and analyses of phylogenetic associations between presence of the premaxillary fraenum and preferred stream substratum were conducted in a clade of closely related darters (snubnose darters and allies) that vary in morphology and habitat preferences. The most recent common ancestor of this clade was inferred to possess a fraenum and to inhabit rocky substrata, consistent with previous hypotheses, but a significant correlation between fraenum presence and substratum type across the phylogeny was not found. © 2015 The Fisheries Society of the British Isles.

    This work describes the potential of chemometric analyses applied to {sup 1}H high-resolution magic angle spinning nuclear magnetic resonance ({sup 1}H HR-MAS NMR) data for the chemotaxonomic investigation of Hancornia speciosa (Apocynaceae) varieties. This plant, popularly known as mangaba, has a complex morphological differentiation and thus chemical analyses can be used for their taxonomic classification. In comparison to traditional techniques, {sup 1}H HR-MAS NMR allied with chemometrics provided a simple and low cost method for chemotaxonomy. Leaves of four varieties of H. speciosa from a common garden experiment was studied and demonstrated that H. speciosa var. speciosa differs from others due to its specific metabolic profile, and var. pubescens was discriminated based on its high phenolic compound content. The distinction between the latter variety and gardineri is important once it allows for the selection of samples with greater commercial value, once they produce the largest and heaviest fruits.

    We investigated the species diversity and phylogeography of the Northeast Asian brown frogs allied to Rana dybowskii (the R. dybowskii species complex: R. dybowskii, R. pirica, and R. uenoi) using four mitochondrial and three nuclear loci. Phylogenetic analyses confirmed the existence of three distinct species in this complex; using extensive molecular data, we confirm the validity of Rana uenoi recognized as a distinct species, and infer R. dybowskii and R. pirica to be sister species. Also, we included populations from previously unsampled regions in Northeast China, and identified them to be R. dybowskii. While many species in Northeast Asia diverged due to Pleistocene glaciation, divergence-dating analyses inferred older, Miocene speciation in the R. dybowskii species complex. Ancestral area reconstruction identified the orogenic movement of the Changbai Mountain Range and the opening of the Sea of Japan/East Sea being major events influencing allopatric speciation.

    The development of aluminum-lithium alloys for aerospace applications requires a thorough understanding of how processing and product geometry impact their microstructure, texture and mechanical properties. The anisotropy of the mechanical properties is in part related to the deformation texture formed during thermo-mechanical processing. In this study, two different extrusions of Al-Li 2099 T83 were characterized, a cylindrical extrusion and an integrally stiffened panel (ISP). A model is proposed to predict mechanical properties and their anisotropy as a function of the <111> fiber texture. Furthermore, the volume fraction of precipitates was measured in zones of high anisotropy (cylindrical extrusion) and low anisotropy (ISP). Results show that there is no significant difference between the two parts concerning volume fraction of precipitates.

    The development of aluminum-lithium alloys for aerospace applications requires a thorough understanding of how processing and product geometry impact their microstructure, texture and mechanical properties. The anisotropy of the mechanical properties is in part related to the deformation texture formed during thermo-mechanical processing. In this study, two different extrusions of Al-Li 2099 T83 were characterized, a cylindrical extrusion and an integrally stiffened panel (ISP). A model is proposed to predict mechanical properties and their anisotropy as a function of the <111> fiber texture. Furthermore, the volume fraction of precipitates was measured in zones of high anisotropy (cylindrical extrusion) and low anisotropy (ISP). Results show that there is no significant difference between the two parts concerning volume fraction of precipitates.

  1. Argentina as an Extra Ally of the United States in NATO

    Full Text Available Few months ago, the United States of America and Argentina signed the agreements to become official allies. Although every alliance is a bilateral fact, it is obvious in this case that it was Argentina that approached the U.S. first and not vice-versa. How can it be explained that a peripheral country, with a long tradition of isolationism, and even confrontation with the Washington, came to be this northern neighbor’s ally? Such a decision was not improvised, rather it was the result of a prolonged process of readjustment in Argentina’s foreign policy. To begin to explain this readjustment, three distinct levels of analysis should be undertaken.The first, the broadest, refers to changes in the international system that affected the way Argentina conceived of its foreign policy. The end of bipolarity altered the equation of costs and benefits of Argentinean diplomacy, raising the costs of isolationism and increasing the incentives for a new bilateral relation with Washington. The second level is more demarcated and refers to the events which influenced Argentinean society and its leadership: the profound transformation of this country’s political culture. A series of values that were absolutely unpopular when the transition to democracy began had become, by the end of the decade, mute points in the process leading to a democratic consensus. The change in the political culture was decisive in the construction of the new foreign policy. The third level of analysis is the most specific: the ideas and leadership style of President Carlos Menem. Though the vision and ideas of this Peronist leader have been fundamental in the decision to establish closer relations with Washington, his decisions are not explicable without reference to the other variables mentioned above.

    Nurses and allied health care professionals (physiotherapists, occupational therapists, speech and language pathologists, dietitians) form more than half of the clinical health care workforce and play a central role in health service delivery. There is a potential to improve the quality of health care if these professionals routinely use research evidence to guide their clinical practice. However, the use of research evidence remains unpredictable and inconsistent. Leadership is consistently described in implementation research as critical to enhancing research use by health care professionals. However, this important literature has not yet been synthesized and there is a lack of clarity on what constitutes effective leadership for research use, or what kinds of intervention effectively develop leadership for the purpose of enabling and enhancing research use in clinical practice. We propose to synthesize the evidence on leadership behaviours amongst front line and senior managers that are associated with research evidence by nurses and allied health care professionals, and then determine the effectiveness of interventions that promote these behaviours. Using an integrated knowledge translation approach that supports a partnership between researchers and knowledge users throughout the research process, we will follow principles of knowledge synthesis using a systematic method to synthesize different types of evidence involving: searching the literature, study selection, data extraction and quality assessment, and analysis. A narrative synthesis will be conducted to explore relationships within and across studies and meta-analysis will be performed if sufficient homogeneity exists across studies employing experimental randomized control trial designs. With the engagement of knowledge users in leadership and practice, we will synthesize the research from a broad range of disciplines to understand the key elements of leadership that supports and enables research use

    Children and adolescents are prolific users of information and communication technologies (ICT) in learning, leisure, and social communication activities. High exposure to ICT is associated with musculoskeletal injuries in adults; however, the management of ICT physical complaints in children is not well-understood. An online survey of allied health professionals (occupational therapists, physiotherapists, and chiropractors) was undertaken to determine (i) the number of children and adolescents in Perth, Western Australia who accessed treatment for musculoskeletal complaints related to use of technology; (ii) the typical frequency and duration of service provision; and (iii) the nature of treatment provided. Costs associated with service provision were estimated. Data from 101 identified the most commonly treated musculoskeletal complaints among children and adolescents included: non-specific neck pain; thoracic postural pain disorder; non-specific low back pain; and lumbar postural pain disorder. Approximately 1445 children were treated in the previous 12 months; with one-third of chiropractors each reported treating 31+ children. Most common treatments were soft tissue release, mobilisation, flexibility and conditioning exercises, soft tissue massage and kinesio-taping. Verbal education about healthy use of technology was provided by most clinicians (88%), with some inconsistent recommendations. The estimated cost of treatment was AUD$1,057,715; of which AUD$544,886 was health system funded. Children and adolescents received allied health treatment for a range of musculoskeletal complaints associated with ICT use. The potential long-term impacts on their health and wellbeing, and the economic burden associated with this health issue warrant the development of systematic risk reduction strategies. © 2016 Occupational Therapy Australia.

  4. Practice development and allied health – a review of the literature

    Full Text Available Background: Practice development is defined as a facilitated process that aims to promote person-centred and evidence-based healthcare. Practice development seeks to engage individuals at all levels of an organisation in order to create positive change. It embraces approaches that are inclusive, participatory and collaborative, but there has been a reported lack of multidisciplinary involvement in its application in practice. Aim: While practice development has been widely adopted by nurses and midwives in New South Wales, Australia, there has been limited application of this approach by allied health professionals (AHPs. This literature review aims to identify published research about the application of practice development methods by AHPs across healthcare settings. Methods: A database review was undertaken using the SCOPUS, CINAHL and Medline databases. The International Practice Development Journal was also searched. A total of 1,672 articles were identified. These were scanned and 413 articles were retrieved, with 55 shortlisted for in-depth review. Results: After application of inclusion and exclusion criteria, 15 journal articles were included in the literature review. Review of the studies identified four areas of primary focus: enhanced multidisciplinary teamwork; practice development frameworks and principles; practice development education and learning programmes; and clinical quality improvement and service delivery outcomes. Conclusions: As the findings showed that there is a limited number of robust research studies on practice development involving AHPs, there are opportunities for the participation of AHPs in practice development and for the study of this involvement. Implications for practice development: There is an opportunity for AHPs to become more involved with practice development Strategies to foster interest and grow understanding of the principles and methods of practice development for allied health are required

    The challenge to increase the efficiency in food production level in Nigeria appears to be more urgent now than it has ever been in the history of the country. This is in view of the rapidly increasing population, the imminent decline in international economic and food aid and the need to conserve foreign exchange earnings through the production of raw materials to feed the growing industrial sector calls for urgent attention. The study was carried out in Ogun State. The descriptive statistics was used to determine the socio-economic characteristics of the respondents. The stochastic frontiers production analysis was applied to estimate the technical, allocative efficiency and economic efficiency among the fish farmers in the state. The results of economic efficiency revealed that fish farming is economically efficient with a range of between 55% and 84% efficiency level suggesting a favourable hope for the agro-allied industry such as poultry and cottage industries etc in the state. The result of hypothesis of inefficiency sources models showed that years of experience of fish farmers is significant at 1% probability level indicating the factor contributing to the fish farming experience in the state. Thus, the efficiency is due to the fact that farmers are experienced and fairly educated. On the basis of findings, policy is suggested to be directed towards the encouragement of entrepreneurs in fish farming in the state by providing enabling environment like credit facilities, public enlightenment programme and provision of social amenities like feeder roads, pipe-born water etc and given the fact that an increase in the level of formal education variable leads to less inefficiency, government policy should be focused on adopting the best technology (e.g. fast growing species and equipment) so as to improve the level of efficiency and investment which shall eventually lead to growth in output of fish farming and a lead to the establishment of agro-allied

    The purposes of this study are to examine differences in job satisfaction among professional groups including nurses, allied hospital professionals, social workers, and elementary school teachers, and to identify specific characteristics of job satisfaction of nurses. The study design was a cross-sectional exploratory study using secondary data analysis with the 2009 Graduates Occupational Mobility Survey. The sample was female new graduates. The differences in job satisfaction among professional groups were analyzed using logistic regression (satisfied vs. not satisfied). Overall, 41.5% of nurses, 50.1% of allied hospital professionals, 58.2% of social workers, and 89% of elementary school teachers were satisfied with their job. Nurses were significantly less satisfied than the other professionals in 5 of the 11 job characteristics and had the lowest odds ratio (OR) when compared with elementary school teachers: work content (OR = 0.197, 95% CI [0.128, 0.304]), physical work environment (OR = 0.353, 95% CI [0.236, 0.529]), working hours (OR = 0.054, 95% CI [0.033, 0.088]), personal growth (OR = 0.242, 95% CI [0.160, 0.366]), and autonomy (OR = 0.188, 95% CI [0.123, 0.288]). Work content, physical work environment, interpersonal relationship, advancement system, and autonomy were significantly associated with the overall job satisfaction of nurses. Relatively dissatisfying job characteristics in nursing work environment that were significant predictors for nurses' job satisfaction should be improved. Newly graduated nurses are at risk for job dissatisfaction. This can result in high turnover rates and can exacerbate the nursing shortage. Efforts to improve the work environment are needed.

    Aluminum and its alloys, due to their low density, high specific strength and high corrosion resistance amongst various structural materials, are used in a wide range of industrial applications for different aqueous solutions. In the present study, we studied effects of Ce addition on microstructure and mechanical properties of Al-2Li-1Cu-0.8Mg-0.1Zr alloys. The melt was held at 780 °C for 20 min and poured into a mold. And as-cast Al alloys were hot-extruded into a plate that was 4 mm in thickness with a reduction ratio of 14:1. The extruded plates were held at 540 °C for 4 hr in water quenching to solution treatment them. As-extruded Al-2Li-1Cu-0.8Mg-0.1Zr-xCe (x = 0.3, 0.6, 0.9 and 1.2 wt.%) alloys are composed of Al, AlLi, AlCuLi and Al11Ce3 phases. By increasing the Ce content from 0 to 1.2 wt.%, the Al11Ce3 phase is increased, after solution treatment the AlLi and AlCuLi phases are decreased. With increasing Ce addition from 0 to 1.2 wt.%, the average grain size of the as-extruded Al alloys were decreased slightly from 100.7, 113.74, 84.3, 74.7 and 61.7 μm and ultimate tensile strength was decreased slightly from 267.59, 264.92, 237.40, 220.93 and 207.83 MPa at room temperature. After solution treatment, ultimate tensile strength was measured with 205.13, 198.12, 195.50, 198.27 and 208.01 MPa at room temperature.

    Full Text Available Abstract Background An economic evaluation of interventions for older people requires accurate assessment of costing and consideration of both acute and long-term services. Accurate information on the unit cost of allied health and community services is not readily available in Australia however. This systematic review therefore aims to synthesise information available in the literature on the unit costs of allied health and community services that may be utilised by an older person living in Australia. Method A comprehensive search of Medline, Embase, CINAHL, Google Scholar and Google was undertaken. Specialised economic databases were also reviewed. In addition Australian Government Department websites were inspected. The search identified the cost of specified allied health services including: physiotherapy, occupational therapy, dietetics, podiatry, counselling and home nursing. The range of community services included: personal care, meals on wheels, transport costs and domestic services. Where the information was not available, direct contact with service providers was made. Results The number of eligible studies included in the qualitative synthesis was fourty-nine. Calculated hourly rates for Australian allied health services were adjusted to be in equivalent currency and were as follows as follows: physiotherapy $157.75, occupational therapy $150.77, dietetics $163.11, psychological services $165.77, community nursing $105.76 and podiatry $129.72. Conclusions Utilisation of the Medicare Benefits Scheduled fee as a broad indicator of the costs of services, may lead to underestimation of the real costs of services and therefore to inaccuracies in economic evaluation.

    Research on patient safety in allied healthcare is scarce. Our aim was to document patient safety in primary allied healthcare in the Netherlands and to identify factors associated with incidents. DESIGN AND SUBJECT: A retrospective study of 1000 patient records in a representative sample of 20 allied healthcare practices was combined with a prospective incident-reporting study. All records were reviewed by trained researchers to identify patient safety incidents. The incidents were classified and analyzed, using the Prevention and Recovery Information System for Monitoring and Analysis method. Factors associated with incidents were examined in a logistic regression analysis. In 18 out of 1000 (1.8%; 95% confidence interval: 1.0-2.6) records an incident was detected. The main causes of incidents were related to errors in clinical decisions (89%), communication with other healthcare providers (67%), and monitoring (56%). The probability of incidents was higher if more care providers had been involved and if patient records were incomplete (37% of the records). No incidents were reported in the prospective study. The absolute number of incidents was low, which could imply a low risk of harm in Dutch primary allied healthcare. Nevertheless, incompleteness of the patient records and the fact that incidents were mainly caused through human actions suggest that a focus on clinical reasoning and record keeping is needed to further enhance patient safety. Improvements in record keeping will be necessary before accurate incident reporting will be feasible and valid.

    There is a lack of detailed evidence about the allied health workforce to inform proposed health care reforms. The South Australian Allied Health Workforce (SAAHW) survey collected data about the demographic characteristics, employment, education and recruitment and retention of allied health professionals in South Australia. The SAAHW questionnaire was widely distributed and 1539 responses were received. The average age of the sample was 40 years; males were significantly older than females, the latter making up 82% of respondents. Three-quarters of the sample worked in the city; 60% worked full time and the remainder in part-time, casual or locum positions. 'Work-life balance' was the most common attraction to respondents' current jobs and 'Better career prospects' the most common reason for intending to leave. Practice in a rural location was influenced by rural background and rural experience during training. A greater proportion of Generation Y (1982-2000) respondents intended to leave within 2 years than Generation X (1961-81) or Baby Boomers (1943-60). Most respondents were satisfied with their job, although some reported lack of recognition of their knowledge and skills. Systematic, robust allied health workforce data are required for integrated and sustainable primary health care delivery.

    Full Text Available Abstract Background Although allied health is considered to be one 'unit' of healthcare providers, it comprises a range of disciplines which have different training and ways of thinking, and different tasks and methods of patient care. Very few empirical studies on evidence-based practice (EBP have directly compared allied health professionals. The objective of this study was to examine the impact of a structured model of journal club (JC, known as iCAHE (International Centre for Allied Health Evidence JC, on the EBP knowledge, skills and behaviour of the different allied health disciplines. Methods A pilot, pre-post study design using maximum variation sampling was undertaken. Recruitment was conducted in groups and practitioners such as physiotherapists, occupational therapists, speech pathologists, social workers, psychologists, nutritionists/dieticians and podiatrists were invited to participate. All participating groups received the iCAHE JC for six months. Quantitative data using the Adapted Fresno Test (McCluskey & Bishop and Evidence-based Practice Questionnaire (Upton & Upton were collected prior to the implementation of the JC, with follow-up measurements six months later. Mean percentage change and confidence intervals were calculated to compare baseline and post JC scores for all outcome measures. Results The results of this study demonstrate variability in EBP outcomes across disciplines after receiving the iCAHE JC. Only physiotherapists showed statistically significant improvements in all outcomes; speech pathologists and occupational therapists demonstrated a statistically significant increase in knowledge but not for attitude and evidence uptake; social workers and dieticians/nutritionists showed statistically significant positive changes in their knowledge, and evidence uptake but not for attitude. Conclusions There is evidence to suggest that a JC such as the iCAHE model is an effective method for improving the EBP knowledge

    Full Text Available Abstract Background Uneven distribution of the medical workforce is globally recognised, with widespread rural health workforce shortages. There has been substantial research on factors affecting recruitment and retention of rural doctors, but little has been done to establish the motives and conditions that encourage allied health professionals to practice rurally. This study aims to identify aspects of recruitment and retention of rural allied health professionals using qualitative methodology. Methods Six focus groups were conducted across rural NSW and analysed thematically using a grounded theory approach. The thirty allied health professionals participating in the focus groups were purposively sampled to represent a range of geographic locations, allied health professions, gender, age, and public or private work sectors. Results Five major themes emerged: personal factors; workload and type of work; continuing professional development (CPD; the impact of management; and career progression. ‘Pull factors’ favouring rural practice included: attraction to rural lifestyle; married or having family in the area; low cost of living; rural origin; personal engagement in the community; advanced work roles; a broad variety of challenging clinical work; and making a difference. ‘Push factors’ discouraging rural practice included: lack of employment opportunities for spouses; perceived inadequate quality of secondary schools; age related issues (retirement, desire for younger peer social interaction, and intention to travel; limited opportunity for career advancement; unmanageable workloads; and inadequate access to CPD. Having competent clinical managers mitigated the general frustration with health service management related to inappropriate service models and insufficient or inequitably distributed resources. Failure to fill vacant positions was of particular concern and frustration with the lack of CPD access was strongly represented by

    Full Text Available When the Nazi Germany attacked the Soviets at the beginning of World War II, the USA, the UK and the Soviet Union took part on the same side and were called the Allies. In order to convey the military aid to the Soviets through Iran, the USA and the UK invaded Iran with the Soviets and dethroned Ahmad Reza Shah, who felt sympathy for Germany. By signing a treaty in 1942, they pledged to evacuate their troops from Iran six months after the war ended. They published a declaration that they would protect Iran’s territorial integrity as well as they repeated these decisions during the conference they made in Tehran in 1943. However; despite these decisions, a hidden rivalry began between the USSR and the West in Iran. The rivalry became very clear towards the end of the war. The Soviets wouldn’t withdraw from Iran. Additionally, they endeavored to divide Iran. The Iran crisis of 1946 between the West and the Soviets formed the start of the Cold War according to some people. As a country, Iran was highly affected by this process.

    2014-01-30

    Clinical reasoning is fundamental to all forms of professional health practice, however it is also difficult to teach and learn because it is complex, tacit, and effectively invisible for students. In this paper we present an approach for teaching clinical reasoning based on making expert thinking visible and accessible to students. Twenty-one experienced allied health clinical educators from three tertiary Australian hospitals attended up to seven action research discussion sessions, where they developed a tentative heuristic of their own clinical reasoning, trialled it with students, evaluated if it helped their students to reason clinically, and then refined it so the heuristic was targeted to developing each student's reasoning skills. Data included participants' written descriptions of the thinking routines they developed and trialed with their students and the transcribed action research discussion sessions. Content analysis was used to summarise this data and categorise themes about teaching and learning clinical reasoning. Two overriding themes emerged from participants' reports about using the 'making thinking visible approach'. The first was a specific focus by participating educators on students' understanding of the reasoning process and the second was heightened awareness of personal teaching styles and approaches to teaching clinical reasoning. We suggest that the making thinking visible approach has potential to assist educators to become more reflective about their clinical reasoning teaching and acts as a scaffold to assist them to articulate their own expert reasoning and for students to access and use.

    The Girl Summit held in 2014 aimed to mobilise greater effort to end Female Genital Mutilation (FGM) within a generation, building on a global movement which viewed the practice as a severe form of violence against women and girls and a violation of their rights. The UN, among others, endorse "comprehensive" strategies to end FGM, including legalistic measures, social protection and social communications. FGM is a sensitive issue and difficult to research, and rapid ethnographic methods can use existing relations of trust within social networks to explore attitudes towards predominant social norms which posit FGM as a social necessity. This study used Participatory Ethnographic Evaluation Research (PEER) to understand young men's (18-25 years) perceptions of FGM, demand for FGM among future spouses, and perceptions of efforts to end FGM in a small town in West Pokot, Kenya, where FGM is reported to be high (between 85% to 96%). Twelve PEER researchers were recruited, who conducted two interviews with their friends, generating a total of 72 narrative interviews. The majority of young men who viewed themselves as having a "modern" outlook and with aspirations to marry "educated" women were more likely not to support FGM. Our findings show that young men viewed themselves as valuable allies in ending FGM, but that voicing their opposition to the practice was often difficult. More efforts are needed by multi-stakeholders - campaigners, government and local leaders - to create an enabling environment to voice that opposition. Copyright © 2016 Elsevier Inc.

    Directory of Open Access Journals (Sweden)

    Anna Maria Fiore-Donno

    Full Text Available The phylogenetic position of the slime-mould genus Lamproderma (Myxomycetes, Amoebozoa challenges traditional taxonomy: although it displays the typical characters of the order Stemonitales, it appears to be sister to Physarales. This study provides a small subunit (18S or SSU ribosomal RNA gene-based phylogeny of Lamproderma and its allies, with new sequences from 49 specimens in 12 genera. We found that the order Stemonitales and Lamproderma were both ancestral to Physarales and that Lamproderma constitutes several clades intermingled with species of Diacheopsis, Colloderma and Elaeomyxa. We suggest that these genera may have evolved from Lamproderma by multiple losses of fruiting body stalks and that many taxonomic revisions are needed. We found such high genetic diversity within three Lamproderma species that they probably consist of clusters of sibling species. We discuss the contrasts between genetic and morphological divergence and implications for the morphospecies concept, highlighting the phylogenetically most reliable morphological characters and pointing to others that have been overestimated. In addition, we showed that the first part (~600 bases of the SSU rDNA gene is a valuable tool for phylogeny in Myxomycetes, since it displayed sufficient variability to distinguish closely related taxa and never failed to cluster together specimens considered of the same species.

  4. Science as an ally of religion: a Muslim appropriation of 'the conflict thesis'.

    Yalcinkaya, M Alper

    2011-06-01

    John W. Draper's History of the Conflict between Religion and Science (1874) is commonly regarded as the manifesto of the 'conflict thesis'. The superficiality of this thesis has been demonstrated in recent studies, but to read Draper's work only as a text on 'science versus religion' is to miss half of its significance, as it also involved evaluations of individual religions with respect to their attitudes towards science. Due to Draper's favourable remarks on Islam, the Ottoman author Ahmed Midhat translated his work into Turkish, and published it along with his own comments on Draper's arguments. Midhat interpreted Islam using the cues provided by Draper, and portrayed it as the only religion compatible with science. While his Christian readers condemned Draper for his approach to Islam, Midhat transformed the 'conflict thesis' into a proclamation that Islam and science were allies in opposition to Christian encroachment on the Ottoman Empire. This paper analyses Midhat's appropriation of Draper's work and compares it to the reaction of Draper's Christian readers. It discusses the context that made an alliance between Islam and science so desirable for Midhat, and emphasizes the impact of the historico-geographical context on the encounters between and representations of science and religion.

    In China, rural areas are a weak link of HIV/AIDS prevention and control. From September 2011, an innovative "county-township-village" allied intervention was implemented in Longzhou County, Guangxi, which assigned the tasks of HIV/AIDS prevention and control to the county Centers for Disease Control and Prevention (CDC), township hospitals, and village clinics, respectively, instead of traditional intervention in which the county CDC undertook the entire work. A 6-year consecutive cross-sectional survey, including 3-year traditional intervention (2009-2011) and 3-year innovative intervention (2012-2014), was conducted to evaluate the effects of the new intervention. Compared to traditional intervention, the innovative intervention achieved positive effects in decreasing risky behaviors. Among female sex workers, condom use rate in the last month increased from 72.06% to 96.82% (p ratio of HIV infection during innovative intervention was 0.631 (95% confidence interval 0.549-0.726) compared with traditional one. Cost-effectiveness analysis indicates that innovative intervention restores each disability-adjusted life year costing an average of $124.26. Taken together, Longzhou's innovative intervention has achieved good effects on HIV/AIDS prevention and control and provides a good reference for rural China.

    Background Subtribe Artemisiinae of Tribe Anthemideae (Asteraceae) is composed of 18 largely Asian genera that include the sagebrushes and mugworts. The subtribe includes the large cosmopolitan, wind-pollinated genus Artemisia, as well as several smaller genera and Seriphidium, that altogether comprise the Artemisia-group. Circumscription and taxonomic boundaries of Artemisia and the placements of these small segregate genera is currently unresolved. Results We constructed a molecular phylogeny for the subtribe using the internal transcribed spacers (ITS) of nuclear ribosomal DNA analyzed with parsimony, likelihood, and Bayesian criteria. The resulting tree is comprised of three major clades that correspond to the radiate genera (e.g., Arctanthemum and Dendranthema), and two clades of Artemisia species. All three clades have allied and segregate genera embedded within each. Conclusions The data support a broad concept of Artemisia s.l. that includes Neopallasia, Crossostephium, Filifolium, Seriphidium, and Sphaeromeria. However, the phylogeny excludes Elachanthemum, Kaschgaria, and Stilnolepis from the Artemisia-group. Additionally, the monophyly of the four subgenera of Artemisia is also not supported, with the exception of subg. Dracunculus. Homogamous, discoid capitula appear to have arisen in parallel four to seven times, with the loss of ray florets. Thus capitular morphology is not a reliable taxonomic character, which traditionally has been one of the defining characters. PMID:12350234

    During the operation "Allied Force" in the spring of 1999, the burning or damaging of industrial and military targets in the Former Republic of Yugoslavia resulted in the release of a large number of chemicals into the atmosphere. The releases contained not only conventional air pollutants, but also Semi-Volatile Organic compounds (SVOs) which are known to be hazardous to health. Under suitable meteorological conditions, these chemicals can be transported across borders over large distances. In this paper, an analysis of measurements and dispersion calculations is presented which provides evidence of pollutant transport from the conflict area to Greece. The measuring program was carried out in Xanthi, Greece and included aerosol sampling and subsequent analysis for the determination of the concentration of SVOs including dioxins, furans, PCBs (PolyChlorinated Biphenyls), PAHs (Polycyclic Aromatic Hydrocarbons) and organic phthalates. This paper focuses on two episodes of organic phthalates that were observed during the conflict period. Pollution measurements are interpreted by means of air trajectories and dispersion calculations. For this purpose, the HYSPLIT_4 (HYbrid Single-Particle Langrangian Integrated Trajectory) modeling system is used to calculate the dispersion of toxic substances.

    Full Text Available The prevalence of obesity is increasing. The potential for allied health professionals to intervene through the provision of lifestyle advice is unknown. This study aimed to determine the knowledge, attitudes and practices of health professionals in the provision of dietary and physical activity advice for clients with overweight or obesity. Dietitians, exercise physiologists, nurses, occupational therapists, physiotherapists and psychologists (n = 296 working in New South Wales were surveyed using paper-based and online methods. The majority of health professionals (71% believed that providing weight management advice was within their scope of practice; 81% provided physical activity advice but only 57% provided dietary advice. Other than dietitians, few had received training in client weight management during their professional qualification (14% or continuing education (16%. Providing dietary advice was associated with: believing it was within their scope of practice (OR 3.9, 95% CI 1.9–7.9, p < 0.01, training during their entry-level qualification (OR 7.2, 3.2–16.4, p < 0.01 and having departmental guidelines (OR 4.7, 2.1–10.9, p < 0.01. Most health professionals are willing to provide lifestyle advice to clients with overweight or obesity but few have received required training. Developing guidelines and training for in client weight management may potentially impact on rising obesity levels.

    The prevalence of autism has increased dramatically. The objectives of this study were to explore attitudes toward prenatal diagnosis to detect autism prenatally and avoid having an affected child and to understand social acceptability of these disorders among students of allied health professions. In this study, college students of nursing and health systems management answered a structured self-report questionnaire (n = 305). The first part addressed the respondent's personal data. The second part targeted the respondent's attitudes toward prenatal diagnosis of non-life-threatening disorders, including autism spectrum disorders. We found that almost two thirds of the students responded that they would not proceed with a pregnancy if the child were diagnosed with autism, and more than half thought that they would not continue with a pregnancy if the fetus were diagnosed with Asperger's. Age, level of religiosity, and years of education were influential. This study is limited in scope; however, the positive attitude of the students toward prenatal diagnosis to avoid having an affected child might also reflect a negative view of autism spectrum disorders in future health care professionals. Further research of attitudes and the social acceptability of autism spectrum disorders, particularly among health care professionals, is required.

    Full Text Available Background: India estimates third highest number of HIV infections in the world, with about 2.4 million people currently living with HIV/AIDS. Adequately trained and sensitized healthcare professionals can play a vital role in combating this epidemic. Limited studies have explored knowledge and attitudes of medical students relating to HIV/AIDS, particularly in the eastern part of India. Methods: The present cross sectional study explored knowledge and attitudes of first year MBBS, BDS & BPT students of Kalinga Institute of Medical Sciences (KIMS, Bhubaneswar, Odisha on HIV/AIDS using a self-administered questionnaire. Data thus collected were analyzedand relevant statistics were calculated. Knowledge and attitude scores were determined and analysis of variance (ANOVA test was used to examine the equality between the groups. Results: All students scored low on the overall knowledge scale (<10/15. Specifically, knowledgewas low on modes of transmission and treatment. Attitudinal scores in the areas of precautions and need for training on HIV was low for all the three streams.The willingness to treat HIV/AIDS patient was found to be high amongst study participants. Conclusion: There is a need and scope to provide correct and detailed information on HIV/AIDS for new entrants in medical and allied health sciences to help them acquire adequate knowledge and develop appropriate attitudes towards HIV/AIDS.

    The objective of this investigation was to establish the relationship between mechanical property anisotropy, microstructure and crystallographic texture in integrally 'T'-stiffened extruded panels fabricated from the Al-Li alloys 2195, 2098 and 2096. In-plane properties were measured as a function of orientation at two locations in the panels, namely mid-way between (Skin), and directly beneath (Base), the integral 'T' stiffeners. The 2195 extrusion exhibited the best combination of strength and toughness, but was the most anisotropic. The 2098 extrusion exhibited lower strength and comparable toughness, but was more isotropic than 2195. The 2096 extrusion exhibited the lowest strength and poor toughness, but was the most isotropic. All three alloys exhibited highly elongated grain structures and similar location-dependent variations in grain morphology. The textural characteristics comprised a beta + fiber texture, similar to rolled product, in the Skin regions and alpha + fiber texture, comparable to axisymmetric extruded product, in the Base regions. In an attempt to quantitatively correlate texture with yield strength anisotropy, the original 'full constraint' Taylor model and a variant of the 'relaxed constraint' model, explored by Wert et al., were applied to the data. A comparison of the results revealed that the Wert model was consistently more accurate than the Taylor model.

    Ahead of the convergence of two major paediatric services, we examined evidence-based practice (EBP) self-efficacy, outcome expectance, knowledge and use among allied health (AH) staff in two major Queensland (Qld) paediatric services. This was to determine whether any differences existed based on organisational affiliation, profession and any previous training to inform a strategy to enhance AH EBP within the new organisational setting. All AH staff from the two Brisbane (Qld) tertiary paedritic hospitals were invited to participate in the survey. Using a cross-sectional design EBP self-efficacy, outcome expectancy, knowledge and use, as well as previous EBP training, were assessed with an online survey. Background demographic information obtained included professional discipline and hospital. One hundreD and thirty-eight health practitioners completed the survey (37% respone rate). Most practioners had accessed EBP training. Mean scores for EBP attitudes (self-efficacy and outcome expectancy) and knowledge were higher than for EBP use scores. Greater variation was observed across professional disciplines than organisations. Training impacted positively on EBP measures but explained a small proportion of total variance in regression models. The results underscore the need to provide organisational supports to AH staff ro EBP implementation. Strategies other than training are requred to maximally enhance EBP attitudes. The new organisational structure provides an oppotunity for this cultural shift to occur.

    The Kansas City Division of AlliedSignal Inc. has been investigating the fabrication and use of piezoelectric motors in mechanisms for United States Department of Energy (DOE) weapons applications for about four years. These motors exhibit advantages over solenoids and other electromagnetic actuators. Prototype processes have been developed for complete fabrication of motors from stock materials, including abrasive machining of piezoelectric ceramics and more traditional machining of other motor components, electrode plating and sputtering, electric poling, cleaning, bonding and assembly. Drive circuits have been fabricated and motor controls are being developed. Laboratory facilities have been established for electrical/mechanical testing and evaluation of piezo materials and completed motors. Recent project efforts have focused on the potential of piezoelectric devices for commercial and industrial use. A broad range of various motor types and application areas has been identified, primarily in Japan. The Japanese have been developing piezo motors for many years and have more recently begun commercialization. Piezoelectric motor and actuator technology is emerging in the United States and quickly gaining in commercial interest. The Kansas City Division is continuing development of piezoelectric motors and actuators for defense applications while supporting and participating in the commercialization of piezoelectric devices with private industry through various technology transfer and cooperative development initiatives.

    The field of social work is attuned to the need to incorporate evidence-based practice education into masters-level curriculum. One question remaining is how to integrate evidence-based practice in the foundation practice courses. Integration of evidence-based practice across the foundation-level curriculum coincides with the Council on Social Work Education's mandate that student's engage in research-informed practice and practice-informed research. Through a discussion of definitions, criticisms, and pedagogy across the allied fields of medicine, nursing, and social work the authors address the current status of evidence-based practice curriculum in foundation-level education. The authors incorporate the lessons learned from allied fields and a Masters of Social Work student's analyses of their experience of evidence-based practice learning to propose an adult-learner model to improve evidence-based practice pedagogy in Social Work.

    Although challenges of anti-racist work are most commonly framed in relation to White people and People of Color, there are significant challenges involved in creating allies across minority racial groups. This article describes our experiences within a community organization aimed at training anti-racist culturally sensitive K-12 educators. As Asian American and Native American facilitators within a group of facilitators of color who were predominantly Black, we describe our experiences of relative marginalization and our (mostly failed) attempts to create change within the organization to be more inclusive of the perspectives, experiences, and needs of non-Black people/students of color. We contextualize these experienced conflicts in relation to race hierarchies, the "divide and conquer strategy" and the maintenance of White privilege. We offer reflections for how racial minorities engaged in anti-racist education could be better allies and how organizations might better foster environments that contribute to the creation of these alliances.

    Trailing intensive cooling with liquid nitrogen has successfully applied to friction stir welding of 2 mm thick 2060 Al-Li alloy. Welding temperature, plastic strain, residual stress and distortion of 2060 Al-Li alloy butt-joint are compared and discussed between conventional cooling and trailing intensive cooling using experimental and numerical simulation methods. The results reveal that trailing intensive cooling is beneficial to shrink high temperature area, reduce peak temperature and decrease plastic strain during friction stir welding process. In addition, the reduction degree of plastic strain outside weld is smaller than that inside weld. Welding distortion presents an anti-saddle shape. Compared with conventional cooling, the reductions of welding distortion and longitudinal residual stresses of welding joint under intense cooling reach 47.7 % and 23.8 %, respectively.

    Full Text Available Abstract Background Allied Health Professionals today are required, more than ever before, to demonstrate their impact. However, despite at least 20 years of expectation, many services fail to deliver routine outcome measurement in practice. This systematic review investigates what helps and hinders routine outcome measurement of allied health professionals practice. Methods A systematic review protocol was developed comprising: a defined search strategy for PsycINFO, MEDLINE and CINHAL databases and inclusion criteria and systematic procedures for data extraction and quality appraisal. Studies were included if they were published in English and investigated facilitators and/or barriers to routine outcome measurement by allied health professionals. No restrictions were placed on publication type, design, country, or year of publication. Reference lists of included publications were searched to identify additional papers. Descriptive methods were used to synthesise the findings. Results 960 papers were retrieved; 15 met the inclusion criteria. Professional groups represented were Physiotherapy, Occupational Therapy, and Speech and Language Therapy. The included literature varied in quality and design. Facilitators and barriers to routine outcome measurement exist at individual, managerial and organisational levels. Key factors affecting professionals’ use of routine outcome measurement include: professionals’ level of knowledge and confidence about using outcome measures, and the degree of organisational and peer-support professionals received with a view to promoting their work in practice. Conclusions Whilst the importance of routinely measuring outcomes within the allied health professions is well recognised, it has largely failed to be delivered in practice. Factors that influence clinicians’ ability and desire to undertake routine outcome measurement are bi-directional: they can act as either facilitators or barriers. Routine outcome

    Workplace learning refers to continuing professional development that is stimulated by and occurs through participation in workplace activities. Workplace learning is essential for staff development and high quality clinical care. The purpose of this study was to explore the barriers to and enablers of workplace learning for allied health professionals within NSW Health. A qualitative study was conducted with a purposively selected maximum variation sample (n =46) including 19 managers, 19 clinicians and eight educators from 10 allied health professions. Seven semi-structured interviews and nine focus groups were audio-recorded and transcribed. The 'framework approach' was used to guide the interviews and analysis. Textual data were coded and charted using an evolving thematic framework. Key enablers of workplace learning included having access to peers, expertise and 'learning networks', protected learning time, supportive management and positive staff attitudes. The absence of these key enablers including heavy workload and insufficient staffing were important barriers to workplace learning. Attention to these barriers and enablers may help organisations to more effectively optimise allied health workplace learning. Ultimately better workplace learning may lead to improved patient, staff and organisational outcomes.

    The purpose of the present study was to determine the aspects of the allied health professional's job that contribute most to job satisfaction and intention to leave in a metropolitan hospital. Data were collected via a questionnaire that was emailed to all clinical allied health staff at Campbelltown and Camden Hospitals in New South Wales, Australia. The participants then rated their level of satisfaction with various job.aspects. A significant correlation was found between several job satisfaction factors and intention to leave in this study group, including quality of supervision, level of competency to do the job, recognition for doing the job, advancement opportunities, autonomy, feelings of worthwhile accomplishment, communication and support from the manager. In relation to Herzberg's job satisfaction theory, both intrinsic and extrinsic work factors have been shown to have a significant correlation with intention to leave in this study group. This information can assist workforce planners to implement strategies to improve retention levels of allied health professionals in the work place.

    2008-01-01

    This study investigated the various reasons that allied health students believe they are currently attending college. The Academic Motivation Scale was administered to a convenience sample of 222 upperclassmen and graduate-level students (162 women, 46 men). The Academic Motivation Scale proposes various reasons for continued engagement in academic pursuits that may be characteristic of personal and current reasons for persistence in a subject's particular academic program. The results showed that students portrayed themselves as currently attending college for both intrinsically and extrinsically motivated reasons. The most frequently endorsed motivational styles were identified (autonomous) extrinsic motivation and externally regulated (nonautonomous) extrinsic motivation. This study showed that this sample of professional-level college students was not completely self-determined in their end-stage academic pursuits. One conclusion that may be drawn from this study is that allied health programs that provide students with an educational context that supports self-determination may encourage future allied health professionals to develop the ability to support the self-determination of their future clients.

    Common mental disorders (CMD) negatively affect work functioning. In the health service sector not only the prevalence of CMDs is high, but work functioning problems are associated with a risk of serious consequences for patients and healthcare providers. If work functioning problems due to CMDs are detected early, timely help can be provided. Therefore, the aim of this study is to develop a detection questionnaire for impaired work functioning due to CMDs in nurses and allied health professionals working in hospitals. First, an item pool was developed by a systematic literature study and five focus group interviews with employees and experts. To evaluate the content validity, additional interviews were held. Second, a cross-sectional assessment of the item pool in 314 nurses and allied health professionals was used for item selection and for identification and corroboration of subscales by explorative and confirmatory factor analysis. The study results in the Nurses Work Functioning Questionnaire (NWFQ), a 50-item self-report questionnaire consisting of seven subscales: cognitive aspects of task execution, impaired decision making, causing incidents at work, avoidance behavior, conflicts and irritations with colleagues, impaired contact with patients and their family, and lack of energy and motivation. The questionnaire has a proven high content validity. All subscales have good or acceptable internal consistency. The Nurses Work Functioning Questionnaire gives insight into precise and concrete aspects of impaired work functioning of nurses and allied health professionals. The scores can be used as a starting point for purposeful interventions.

    Full Text Available Les implants orthopédiques de hanche ont une durée de vie d'environ 15 ans. Par exemple, la tige fémorale d'un tel implant peut être réalisée en acier inoxydable 316L ou 316LN. Le fretting corrosion, frottement sous petits déplacements, peut se produire pendant la marche humaine en raison des chargements répétés entre le métal de la prothèse et l'os. Plusieurs investigations expérimentales du fretting corrosion ont été entreprises. Cette couche passive de quelques nanomètres, à température ambiante, est le point clef sur lequel repose le développement de notre civilisation, selon certains auteurs. Ce travail vise à prédire les épaisseurs de cette couche passive de l'acier inoxydable soumis au fretting corrosion, avec une attention spécifique sur le rôle des protéines. Le modèle utilisé est basé sur le Point Defect Model, PDM (à une échelle microscopique et une amélioration de ce modèle en prenant en compte le processus de frottement sous petits débattements. L'algorithme génétique a été utilisé pour optimiser la convergence du problème. Les résultats les plus importants sont, comme démontré avec les essais expérimentaux, que l'albumine, la protéine étudiée, empêche les dégradations de l'acier inoxydable aux plus faibles concentrations d'ions chlorure ; ensuite, aux plus fortes concentrations de chlorures, un temps d'incubation est nécessaire pour détruire le film passif. Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un-loadings, between stainless steel and bone for instance. Some experimental investigations of fretting corrosion have been practiced. As well known, metallic alloys and especially stainless steels are covered with a passive film that prevents from the corrosion and degradation

    Evidence-based practice (EBP) is fundamental to improving patient outcomes. Universal adoption of EBP into the allied health clinical setting has not yet occurred. The primary aim of this project was to capture baseline measurements of the level of EBP self-efficacy, outcome expectancy, knowledge and use at our health service prior to training and organisational changes to support EBP. All allied health staff (n=252) employed across the campus were invited to participate in an online survey consisting of a battery of validated and reliable survey tools. Professional background, knowledge and previous training in EBP and research processes were collected. One hundred eighty-two allied health staff completed the survey (response rate 72%). One-way ANOVAs were used to compare levels of self-efficacy, outcome expectancy, knowledge and use, according to allied health discipline and experience with EBP and research processes. Mean scores for EBP attitudes (self-efficacy and outcome expectancy) and knowledge were higher than for use. Professional group differences were noted in the post-hoc analysis of the significant EBP constructs. Regression analyses indicated that EBP course attendance as well as training in research design and analysis impacted positively on EBP construct scores. Despite positive attitudes about, a belief in and knowledge of EBP, self-reports of EBP processes do not indicate systematic application in the allied health workplace. The results of this research will inform a targeted intervention to foster ongoing training in EBP and research activity for allied health staff.

    Mandatory versus voluntary requirement has moderating effect on a person's intention to use a new information technology. Studies have shown that the use of technology in health care settings is predicted by perceived ease of use, perceived usefulness, social influence, facilitating conditions, and attitude towards computer. These factors have different effects on mandatory versus voluntary environment of use. However, the degree and direction of moderating effect of voluntariness on these factors remain inconclusive. This study aimed to examine the moderating effect of voluntariness on the actual use of an electronic health record (EHR) designed for use by allied health professionals in Hong Kong. Specifically, this study explored and compared the moderating effects of voluntariness on factors organized into technology, implementation, and individual contexts. Physiotherapists who had taken part in the implementation of a new EHR were invited to complete a survey. The survey included questions that measured the levels of voluntariness, technology acceptance and use, and attitude towards technology. Multiple logistic regressions were conducted to identify factors associated with actual use of a compulsory module and a noncompulsory module of the EHR. In total, there were 93 participants in the study. All of them had access to the noncompulsory module, the e-Progress Note, to record progress notes of their patients. Out of the 93 participants, 57 (62%) were required to use a compulsory module, the e-Registration, to register patient attendance. In the low voluntariness environment, Actual Use was associated with Effort Expectancy (mean score of users 3.51, SD 0.43; mean score of non-users 3.21, SD 0.31; P=.03). Effort Expectancy measured the perceived ease of use and was a variable in the technology context. The variables in the implementation and individual contexts did not show a difference between the two groups. In the high voluntariness environment, the mean

Background: Determining what constitutes an excellent allied health care professional (AHCP is important, since this is what will guide the development of curricula for training future physical therapists, oral hygienists, speech therapists, diagnostic radiographers, and dietitians. This also determines the quality of care. Aim: To describe perspectives of AHCPs on which characteristics are commonly associated with an excellent AHCP. Methods: AHCPs' perspectives were derived from three focus group discussions. Twenty-one health care professionals participated. The final analysis of the focus group discussions produced eight domains, in which content validity was obtained through a Delphi panel survey of 27 contributing experts. Results: According to the survey, a combination of the following characteristics defines an excellent AHCP: (1 cognizance, to obtain and to apply knowledge in a broad multidisciplinary health care field; (2 cooperativity, to effectively work with others in a multidisciplinary context; (3 communicative, to communicate effectively at different levels in complex situations; (4 initiative, to initiate new ideas, to act proactively, and to follow them through; (5 innovative, to devise new ideas and to implement alternatives beyond current practices; (6 introspective, to self-examine and to reflect; (7 broad perspective, to capture the big picture; and (8 evidence-driven, to find and to use scientific evidence to guide one's decisions. Conclusion: The AHCPs perspectives can be used as a reference for personal improvement for supervisors and professionals in clinical practice and for educational purposes. These perspectives may serve as a guide against which talented students can evaluate themselves. Keywords: clinical

    Forty brands of tobacco used in Indian cigarettes, 20 brands of bidis (tobacco rolled in wrapper leaves), 15 brands of chewing tobacco and 15 brands of snuff tobacco were analyzed by nuclear and allied techniques. The elements measured into tobacco can be grouped into seven categories from less than 1 ppm to 5% by weight. Concentration level varied from 0.5-5% for (Ca, K, Cl), 400-1500 ppm (Fe), 200-600 ppm (Na), 100-300 ppm (Ti, Mn, Br and Sr), 10-100 ppm (Cu, Zn and Rb), 1-10 ppm (Cr, Ni, Pb and La) and less than 1 ppm (As, Co, Cd, Sb, Hg and Eu). Among the above elements Cr, Ni, As, Cd, Pb, Hg and Sb are considered toxic. The percentage transfer of the elements from cigarette tobacco to smoke particles during smoking was also estimated using a smoking machine and collecting the smoke particles on a filter paper. The results show that Br, Cr, Sb and Zn have high percentage transfer from tobacco to its smoke of the order of 2-15%. Out of these Sb has the highest 15%. Cobalt, Fe and Sc have lowest percentage of transfer of the order of less than 1%. The percent transfer of these elements from tobacco to tobacco smoke is higher in case of bidis (1.5-3.0 times) as compared to cigarettes. In cigarettes also non-filter cigarettes have higher transfer (2-3 times) as compared to filter tip cigarettes. (author)

    Full Text Available Introduction: After the signing of the alliance among Japan, Germany and Italy’s governments in September 1940, several journals arose in order to spread the Japanese culture among people who knew very little about Italy’s new allied. Some documentaries also had the same function. Methods: The numerous textual and iconographical references concerning the Japanese warriors’ anthropology published in some Italian magazines during the 1940s have been compared, as well as to the few Italian monographs on the same theme and to some documentaries by Istituto Nazionale Luce, government propaganda organ. This subject has also been compared to the first Italian cultural production, concerning Japan, which dated back to the first decades of the 20th century. Moreover different intellectuals’ biographies of those times have been deeply analyzed. Results: Comparing to each other the anthropological references about Japan in the Italian cultural production during the Second World War, we can notice a significant ideological homogeneity. This can be explained through their writers’ common sharing of the militaristic, hierarchical and totalitarian doctrine of the Fascist Regime. The Fascist ideology can be summarized in the Bushido concept, as Inazo Nitobe defined it in 1916. This concept was already known in Italy on the early 20th century, far before Fascism. Discussions and conclusions: We can see how Italian perception of the Japanese anthropology on the early 20th century didn’t change over time and how its features will re-appear in the 40s under the influence of the Italian-Japanese coalition. So, Bushido became the essence of the Japanese military and national identity that Fascist Italy took as example for mass education. Some of these stereotypes will re-appear after the war and until recent times in popular culture and in mass perception of Japanese martial arts.

    Full Text Available Social work is a complex and multidisciplinary field drawing on a wide range of literature in terms of format, age, and discipline. Librarians in both collections and public services must be aware of this diversity in order to serve this rapidly growing field. This study was designed to identify core journals in the social work field, the most commonly cited formats and the age of citations, to assess the use of non-social work journals in the social work literature, and to draw comparisons to results in allied health and social science disciplines. The ultimate goal of this work is to provide librarians supporting social work programs with data which can contribute to their assessment of collections, both for maintenance and accreditation, and which can allow them to have a broader understanding of the field and a more effective approach to instruction. 28,269 citations from 567 source articles were examined. Journal articles were the most commonly cited format (69.90%, followed by books (17.69%. Over 91% of all citations came from materials published after 1990 and over 50% of citations came from materials published in the last ten years. Of the 2,520 journals cited, 32 top journals (1.27% accounted for 6,612 (33.46% of all citations to journals. Of those 32 journals, six were assigned to the field of social work. The remaining core journals came from the fields of psychology, public health, psychiatry, family and gender studies, pediatrics, and medicine. Format distribution and citation age were found to be similar to that of psychology, health care management, health education, and nurse practitioners. There was little similarity with the fields of addictions treatment and sociology. Practical implications for librarians are discussed.

This classification was established as follows: i) The in-phase tests with two or three components (δ = \\varphi = 0^circ); no supplementary hardening is observed. ii) The tension-pressure tests such as r_1 = 1, \\varphi = 90^circ and r_1 = - 1, \\varphi = 60^circ, the hardening is slightly inferior to that of tension-torsion tests. iii) The tension-torsion tests such as r_2 = 1 and δ = 90^circ, where a substantial additionnal hardening takes place. iv) The tension-torsion-pressure tests where the three components are strongly shifted, namely: r_1 = r_2 = 1, δ = 90^circ and \\varphi = 60^circ, and r_2 = 1, r_1 = -1, δ = 41.4^circ and \\varphi = 82.8^circ. The hardening is slightly superior to the one recorded in tension-torsion. A more thorough study is in preparation which considers all the possible combinations in tension-torsion-pressures, and will be performed on the same material.

    The present study has been undertaken to investigate the mechanisms of thermal stress relief at the range of temperatures below room temperature for the metal matrix composite Al-Li 8090/SiC. For this aim the experimental technique of internal friction has been used which has been showed up very effective. Several thermal cycles from 453 K to 100 K were used in order to measures the internal friction as well as the elastic modules of the material concluding that thermal stresses are relaxed by microplastic deformation around the reinforcements. It has been also related the variation in the elastic modules with the different levels of precipitation. (Author) 18 refs.

    In a trial to find whether or not the enlarged spleen plays a role in the production of the form of anaemia commonly encountered in leukaemias and allied conditions, 44 patients suffering from these disease states were studied using {sup 51}Cr-labelled erythrocytes heated at 50 Degree-Sign C for 60 min. Cells altered in this manner have been shown by various workers to be selectively sequestered by the spleen. As a control, the test was performed on 24 normal subjects. In these normals, the disappearance half-time of radioactivity from the circulation (T{sub Vulgar-Fraction-One-Half} amounted to 172 {+-} 69 min (mean {+-} 1 S.D.), the lowest limit being 74 min. Accordingly, patients with less than 74 min were considered to have an abnormally rapid disappearance of heat-treated erythrocytes from the circulation and consequently exaggerated splenic sequestration of these altered cells. Splenic trapping of heat-treated erythrocytes was most marked in acute leukaemia (four out of six patients). However, three had associated normoblastic hypoplasia of the sternal marrow. Corticosteroids induced a remission with reversion of both processes responsible for the anaemia in two out of the four patients. In chronic myeloid leukaemia, exaggerated splenic sequestration of altered cells was seen in four of the 15 cases examined. This condition was of extra-erythrocytic origin, since repetition of the test using normal donor heat-treated erythrocytes did not significantly alter the disappearance half-time. However, there was no correlation between the size of the spleen and its avidity for trapping the altered cells. Follow-up studies showed that therapy caused prolongation of the half-time of heat-treated erythrocytes, the effect being more apparent after corticosteroids than with X-rays or Endoxan, In Hodgkin's disease, increased red cell trapping was observed in two out of the seven patients studied. In contrast, five cases of chronic lymphatic leukaemia, six lymphosarcoma and

    Allied health professionals working in rural areas face unique challenges, often with limited access to resources. Accessing continuing professional development is one of those challenges and is related to retention of workforce. Effectiveness of distance learning strategies for continuing professional development in rural allied healthcare workers has not been evaluated. We searched 17 databases and the grey literature up to September 2016 following the PRISMA guidelines. Any primary studies were included that focussed on allied health and distance delivery regardless of education topic or study design. Two independent reviewers extracted data and critically appraised the selected studies. The search returned 5257 results. With removal of duplicate references, we reviewed 3964 article titles and abstracts; n = 206 appeared potentially eligible and were scrutinised via full text screening; n = 14 were included. Studies were published between 1997 and 2016, were of varied methodological quality and were predominantly from Australia, USA and Canada with a focus on satisfaction of learners with the delivery method or on measures of educational outcomes. Technologies used to deliver distance education included video conference, teleconference, web based platforms and virtual reality. Early papers tended to focus more on the technology characteristics than educational outcomes. Some studies compared technology based delivery to face to face modes and found satisfaction and learning outcomes to be on par. Only three studies reported on practice change following the educational intervention and, despite a suggestion there is a link between the constructs, none measured the relationship between access to continuing professional development and workforce retention. Technology based options of delivery have a high utility, however the complex inter-relatedness of time, use, travel, location, costs, interactivity, learning outcomes and educational design suggest a need

    Harrell, Leigh S.

    The purpose of this study was two-fold. First the study was designed to determine student perceptions regarding the perceived degree of original learning from a human anatomy and physiology course, and the student perception of the use of the knowledge in an allied health program. Second, the intention of the study was to establish student beliefs on the characteristics of the transfer of learning including those factors which enhance learning transfer and those that serve as barriers to learning transfer. The study participants were those students enrolled in any allied health program at a community college in a Midwest state, including: nursing, radiology, surgical technology, health information technology, and paramedic. Both quantitative and qualitative data were collected and analyzed from the responses to the survey. A sub-group of participants were chosen to participate in semi-structured formal interviews. From the interviews, additional qualitative data were gathered. The data collected through the study demonstrated student perception of successful transfer experiences. The students in the study were able to provide specific examples of learning transfer experienced from the human anatomy and physiology course in their allied health program. Findings also suggested students who earned higher grades in the human anatomy and physiology course perceived greater understanding and greater use of the course's learning objectives in their allied health program. The study found the students believed the following learning activities enhances the transfer of learning: (1) Providing application of the information or skills being learned during the instruction of the course content enhances the transfer of learning. (2) Providing resource materials and activities which allow the students to practice the content being taught facilitates the transfer of learning. The students made the following recommendations to remove barriers to the transfer of learning: (1

A systematic approach to evaluating the evidence of the experience and effects of professional supervision for non-metropolitan allied health practitioners and their service delivery is needed. Methods: Studies investigating the experience and effects of professional supervision across 17 allied health disciplines in non-metropolitan health services were systematically searched for using standardized keywords across seven databases. The initial search identified 1,574 references. Of these studies, five met inclusion criteria and were subject to full methodological appraisal by both reviewers. Two studies were primarily qualitative with three studies primarily quantitative in their approach. Studies were appraised using McMaster critical appraisal tools and data were extracted and synthesized. Results: Studies reported the context specific benefits and challenges of supervision in non-metropolitan areas and the importance of supervision in enhancing satisfaction and support in these areas. Comparison of findings between metropolitan and non-metropolitan settings within one study suggested that allied health in non-metropolitan settings were more satisfied with supervision though less likely to access it and preferred supervision with other non-metropolitan practitioners over access to more experienced supervisors. One study in a regional health service identified the lack

    Full Text Available Trans people—and particularly trans youth—have come to the forefront of political and educational discussions, especially as legislation has aimed to ensure that school personnel act as enforcers of state-level policies targeting trans youth. For this reason, and because research demonstrates that youth in schools form attachments to and receive support from school personnel, our research looks at school personnel’s development as allies. By analyzing focus group data following a training workshop, we explore how participants understand their roles as allies to trans and gender non-conforming youth. We found that trans issues were salient and participants expressed new knowledge about and openness towards transgender youth, as well as care and concern for their wellbeing. Nonetheless, many participants retained frames of understanding that relied on trans people as Other and that situated their roles as allies through the frameworks of protection and care. We argue that these understandings of trans youth and the role of allies reinforces cisnormativity, and we push for a more nuanced understanding of allyship that moves beyond knowledge, beliefs, attitudes and intended behaviors as markers of allyship to ensure that allies do not reproduce cisnormativity even in their support of trans and gender non-conforming youth.

This is largely related to the complexity of the AH discipline-mix, the services these disciplines provide, and the locations in which services are provided. AH is variably described, with up to 49 disciplines being listed in the literature. These disciplines often undertake a range of interlinked activities such as assessment and diagnosis, counseling, therapy and rehabilitation, manufacture, education, and service organization. AH disciplines work in a range of roles in a range of public and private sector organizations, and often consult with their patients/clients a number of times for the management of one condition. They operate under a variety of funding models, and often within service delivery constraints. This evidence-informed analytical review outlines factors which should be considered by allied health leaders, reflecting clinicians, policy-makers, managers, and academics, in regards to making an informed choice of sensitive and reliable measures of AH service quality. Strong, visionary, and collaborative leadership is required to ensure that allied health activities and outcomes are measured and reported effectively and efficiently.Keywords: allied health (AH, sensitive, reliable measures, health service quality

    Improving the quality and safety of health care in Australia is imperative to ensure the right treatment is delivered to the right person at the right time. Achieving this requires appropriate clinical governance and support for health professionals, including professional supervision. This study investigates the usefulness and effectiveness of and barriers to supervision in rural and remote Queensland. As part of the evaluation of the Allied Health Rural and Remote Training and Support program, a qualitative descriptive study was conducted involving semi-structured interviews with 42 rural or remote allied health professionals, nine operational managers and four supervisors. The interviews explored perspectives on their supervision arrangements, including the perceived usefulness, effect on practice and barriers. Themes of reduced isolation; enhanced professional enthusiasm, growth and commitment to the organisation; enhanced clinical skills, knowledge and confidence; and enhanced patient safety were identified as perceived outcomes of professional supervision. Time, technology and organisational factors were identified as potential facilitators as well as potential barriers to effective supervision. This research provides current evidence on the impact of professional supervision in rural and remote Queensland. A multidimensional model of organisational factors associated with effective supervision in rural and remote settings is proposed identifying positive supervision culture and a good supervisor-supervisee fit as key factors associated with effective arrangements. © 2015 Commonwealth of Australia.

    Full text: Forensic science deals with the application of various techniques for physics, chemistry and biology for crime investigation. The legal implication of such analysis put considerable restriction on the choice of analytical techniques. Moreover, the unknown nature of the materials, the limited availability of samples and the large number of elements to be analysed put considerable strain on the analytical chemist on the selection of the appropriate technique. The availability of nuclear techniques has considerably enhanced the scope of forensic analysis. This paper deals with the recent results on the use of nuclear and allied analytical techniques for forensic applications. One of the important types of samples of forensic importance pertain to the identification of gunshot residues. The use of nuclear techniques has considerably simplified the interpretation of results through the use of appropriate elements like Ba, Cu, Sb, Zn, As and Sn etc. The combination of non-nuclear techniques for elements like Pb and Ni which are not easily amenable to be analysed by NAA and the use of appropriate separation procedure has led to the use of this method as a valid and versatile analytical procedure. In view of the presence of a large amounts of extraneous materials like cloth, body tissues etc in these samples and the limited availability of materials, the procedures for sample collection, dissolution and analysis have been standardized. Analysis of unknown materials like powders, metallic pieces etc. for the possible presence of nuclear materials or as materials in illicit trafficking is becoming important in recent years. The use of multi-technique approach is important in this case. Use of non-destructive techniques like XRF and radioactive counting enables the preliminary identification of materials and for the detection of radioactivity. Subsequent analysis by NAA or other appropriate analytical methods allows the characterization of the materials. Such

    This paper discusses how psychoanalytic ideas were brought to bear in the Allied struggle against the Third Reich and explores some of the claims that were made about this endeavour. It shows how a variety of studies of Fascist psychopathology, centred on the concept of superego, were mobilized in military intelligence, postwar planning and policy recommendations for ‘denazification’. Freud’s ideas were sometimes championed by particular army doctors and government planners; at other times they were combined with, or displaced by, competing, psychiatric and psychological forms of treatment and diverse studies of the Fascist ‘personality’. This is illustrated through a discussion of the treatment and interpretation of the deputy leader of the Nazi Party, Rudolf Hess, after his arrival in Britain in 1941. PMID:19791314

    The computer program PROSA (PROgram for Statistical Analysis of near-real-time accountancy data) was developed as a tool to apply statistical test procedures to a sequence of materials balance results for detecting losses of material. First applications of PROSA to model facility data and real plant data showed that PROSA is also usable as a tool for process or measurement control. To deepen the experience for the application of PROSA to real data of bulk-handling facilities, we applied it to uranium data of the Allied General Nuclear Services miniruns, where accountancy data were collected on a near-real-time basis. Minirun 6 especially was considered, and the pulsed columns were chosen as materials balance area. The structure of the measurement models for flow sheet data and actual operation data are compared, and methods are studied to reduce the error for inventory measurements of the columns

    A commercial 2091 aluminium-lithium alloy was subjected to various aging treatments to produce different metastable precipitates. The nature of the precipitates was deduced from differential thermal analysis and by reference to the literature. The Al L{sub 2,3} and the Li K beta spectra were recorded. The average energy of the Al L{sub 2,3} emission band from the matrix was taken to be a measure of the overall energy of the valence electrons, and a direct correlation was established between the valence electron energy and the hardness of the alloy. The Li K beta spectra from lithium concentrated in the precipitates showed considerable structure not present in the spectrum from the pure metal, and which is related to covalency in the Al-Li bonds.

    Full Text Available Le procédé de soudage hybride Arc/Laser est une solution aux assemblages difficiles de tôles de fortes épaisseurs. Ce procédé innovant associe deux sources de chaleur : un arc électrique produit par une torche MIG et une source laser placée en amont. Ce couplage améliore le rendement du procédé, la qualité du cordon et les déformations finales. La modélisation de ce procédé par une approche Level Set permet une prédiction du développement du cordon et du champ de température associé. La simulation du soudage multi-passes d'une nuance d'acier 18MnNiMo5 est présentée ici et les résultats sont comparés aux observations expérimentales. The hybrid arc/laser welding process has been developed in order to overcome the difficulties encountered for joining high thickness steel sheets. This innovative process gathers two heat sources: an arc source developed by a MIG torch and a pre-located laser source. This coupling improves the efficiency of the process, the weld bead quality and the final deformations. The Level-Set approach for the modelling of this process enables the prediction of the weld bead development and the temperature field evolution. The simulation of the multi-passes welding of a 18MnNiMo5 steel grade is detailed and the results are compared to the experimental observations.

    Medicare items were introduced in 2005 to encourage general practitioners (GPs) to involve other healthcare providers in the management of patients with chronic disease. However, there appears to be barriers to converting financial incentives and the use of information technology as a communication tool to better patient outcomes. The aim of this study was to explore these barriers from the perspectives of practice nurses and allied health practitioners. Three focus groups were held, comprising a convenience sample of 10 practice nurses and 17 allied health professionals from south-east Melbourne. FINDINGS were reported under five themes: (1) attitudes and beliefs, (2) communication using care planning documents, (3) electronic communication, (4) care planning and collaboration between healthcare professionals and (5) ongoing challenges. While allied professionals use care planning tools, there is confusion about the extent to which these tools are for the GPs to provide structured care to assist with communication or funding mechanisms for allied health services. Further research is needed on the contributions of these groups to the care planning process and how communication and collaboration between healthcare professionals can be strengthened.

    It has been recognized in the allied health professions that allied health disciplines must enhance and increase their research and scholarly activity. If faculty/staff are to be judged in the academic environment in which they work, their efforts to conduct research must be supported. Recognition for academic scholarship measured by the performance of research and scholarly activity is often difficult for faculty/staff to attain because of increased demands for scheduled time devoted to classroom instruction and student advising. This inability for faculty/staff to engage in research and scholarly activity often is enhanced by the lack of proper and adequate facilities and equipment. Also important is the role of graduate education, which itself, provides a stimulus for the performance of research and scholarly activity. This article reports outcomes achieved by an international faculty/staff-student program that provides an opportunity for faculty/staff and students within an allied health discipline to conduct research and scholarly activity. This program could serve as a model to identify the strengths and benefits that can be achieved by such programs. This program is capable of improving the research and scholarly activity of all academic units within an allied health discipline.

    Kinesiology departments have recently started to offer allied health education programs to attract additional students to teacher education units (9). Although allied health professions offer increased work opportunities, insufficient enrollment and training of minority students in these academic fields contribute to underrepresentation in the workforce (3). To improve workforce diversity, kinesiology departments must understand how enrollment influences and barriers differ by race among prospective students. Therefore, the purpose of this study was to identify differences in allied health education enrollment influences and enrollment barriers between minority and Caucasian students. Participants (n = 601) consisted of students enrolled in kinesiology-based allied health education programs. Multivariate ANOVA was used to compare group differences in enrollment decision making. "Personal influence," "career opportunity," and "physical self-efficacy" were all significantly stronger enrollment influences among African-American students than among Caucasian students, and "social influence," "experiential opportunity," "academic preparation," and "physical self-efficacy" were all perceived as significantly greater barriers compared with Caucasian students. Findings support the need to recruit African-American students through sport and physical education settings and to market program-based experiential opportunities.

    The optimum supply of an allied health workforce in rural and remote communities is a persistent challenge. Despite previous indicative research and government investment, the primary focus for rural and remote recruitment has been on the medical profession. The consequent shortage of allied health professionals leaves these communities less able to receive appropriate health care. This comprehensive review incorporates a literature analysis while articulating policy and further research implications. The objective was to identify drivers to recruitment and retention of an allied health workforce in rural and remote communities. This issue was observed in two parts: identification of barriers and enablers for students accessing allied health undergraduate tertiary education, and barriers and enablers to clinical placement experience in rural and remote communities. A search of empirical literature was conducted together with review of theoretical publications, including public health strategies and policy documents. Database searches of CINAHL, Medline, ERIC, PsychInfo and Scopus were performed. Selection criteria included Australian research in English, full text online, keywords in title or abstract, year of publication 1990 to 2012 and research inclusive of rural and remote context by application of the Australian Standard Geographical Classication (ASGC) Remoteness Structure. Theoretical publications, or grey literature, were identified by broad Google searches utilising a variety of search terms relevant to the review objective. Allied health professions were defined as including audiology, dietetics, occupational therapy, optometry, orthoptics, orthotics and prosthetics, pharmacy, physiotherapy, podiatry, psychology, radiography, social work, speech pathology and Aboriginal and Torres Strait Islander Health Workers. A total of 28 empirical publications met the selection criteria with a further 22 grey literature texts identified with relevance to the research

    Hepatectomy is the optimal method for liver cancer; the virtual liver resection based on three-dimensional visualization technology (3-DVT) could provide better preoperative strategy for surgeon. We aim to introduce right posterior lobe allied with part of V and VIII sectionectomy assisted by 3-DVT as a promising treatment for massive or multiple right hepatic malignancies to retain maximum residual liver volume on the basis of R0 resection. Among 126 consecutive patients who underwent hepatectomy, 9 (7%) underwent right posterior lobe allied with part of V and VIII sectionectomy. 21 (17%) underwent right hemihepatectomy (RH). The virtual RH was performed with 3-DVT, which provided better observation of spatial position relationship between tumor and vessels, and the more accurate estimation of the remnant liver volume. If remnant liver volume was right posterior lobe allied with part of V and VIII sectionectomy should be undergone. Then, the precut line ought to be planned on the basis of protecting the portal branch of subsegment 5 and 8. The postoperative outcome of patients was compared before and after propensity score matching. Nine patients meeting the eligibility criteria received right posterior lobe allied with part of V and VIII sectionectomy. The variables, including the overall mean operation time, blood transfusion, operation length, liver function, and postoperative complications, were similar between two groups before and after propensity matching. The postoperative first, third, fifth, and seventh days mean value of aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin (ALB), and total bilirubin had no significant difference compared with preoperative value. One patient in each group had recurrence six months after surgery. Right posterior lobe allied with part of V and VIII sectionectomy based on 3-DVT is safe and feasible surgery way, and can be a very promising method in massive or multiple right hepatic malignancy therapy.

    Full Text Available Abstract Background Safe and timely access to effective and appropriate medication through primary care settings is a major concern for all countries addressing both acute and chronic disease burdens. Legislation for nurses and other professionals allied to medicine to prescribe exists in a minority of countries, with more considering introducing legislation. Although there is variation in the range of medicines permitted to be prescribed, questions remain as to the contribution prescribing by nurses and professionals allied to medicine makes to the care of patients in primary care and what is the evidence on which clinicians, commissioners of services and policy makers can consider this innovation. Methods A integrative review of literature on non-medical prescribing in primary care was undertaken guided by dimensions of health care quality: effectiveness, acceptability, efficiency and access. Results 19 papers of 17 empirical studies were identified which provided evidence of patient outcome of non medical prescribing in primary care settings. The majority were undertaken in the UK with only one each from the USA, Canada, Botswana and Zimbabwe. Only two studies investigated clinical outcomes of non-medical prescribing. Seven papers reported on qualitative designs and four of these had fewer than ten participants. Most studies reported that non medical prescribing was widely accepted and viewed positively by patients and professionals. Conclusions Primary health care is the setting where timely access to safe and appropriate medicines is most critical for the well-being of any population. The gradual growth over time of legislative authority and in the numbers of non-medical prescribers, particularly nurses, in some countries suggests that the acceptability of non-medical prescribing is based on the perceived value to the health care system as a whole. Our review suggests that there are substantial gaps in the knowledge base to help evidence

    Policy initiatives to improve retention of the rural health workforce have relied primarily on evidence for rural doctors, most of whom practice under a private business model. Much of the literature for rural allied health (AH) workforce focuses on the public sector. The AH professions are diverse, with mixed public, private or combined practice settings. This study explores sector differences in factors affecting retention of rural AH professionals. This study compared respondents from the 2008 Rural Allied Health Workforce (RAHW) survey recruiting all AH professionals in rural New South Wales. Comparisons between public (n = 833) and private (n = 756) groups were undertaken using Chi square analysis to measure association for demographics, job satisfaction and intention to leave. The final section of the RAHW survey comprised 33 questions relating to retention. A factor analysis was conducted for each cohort. Factor reliability was assessed and retained factors were included in a binary logistic regression analysis for each cohort predicting intention to leave. Six factors were identified: professional isolation, participation in community, clinical demand, taking time away from work, resources and 'specialist generalist' work. Factors differed slightly between groups. A seventh factor (management) was present only in the public cohort. Gender was not a significant predictor of intention to leave. Age group was the strongest predictor of intention to leave with younger and older groups being significantly more likely to leave than middle aged.In univariate logistic analysis (after adjusting for age group), the ability to get away from work did not predict intention to leave in either group. In multivariate analysis, high clinical demand predicted intention to leave in both the public (OR = 1.40, 95% CI = 1.08, 1.83) and private (OR = 1.61, 95% CI = 1.15, 2.25) cohorts. Professional isolation (OR = 1.39. 95% CI = 1.11, 1.75) and Participation in community (OR = 1

    Evidence-based practice aims to achieve better health outcomes in the community. It relies on high quality research to inform policy and practice; however research in primary health care continues to lag behind that of other medical professions. The literature suggests that research capacity building (RCB) functions across four levels; individual, team, organisation and external environment. Many RCB interventions are aimed at an individual or team level, yet evidence indicates that many barriers to RCB occur at an organisational or external environment level. This study asks senior managers from a large healthcare organisation to identify the barriers and enablers to RCB. The paper then describes strategies for building allied health (AH) research capacity at an organisational level from a senior managers' perspective. This qualitative study is part of a larger collaborative RCB project. Semi-structured in-depth interviews were conducted with nine allied health senior managers. Recorded interviews were transcribed and NVivo was used to analyse findings and emergent themes were defined. The dominant themes indicate that the organisation plays an integral role in building AH research capacity and is the critical link in creating synergy across the four levels of RCB. The organisation can achieve this by incorporating research into its core business with a whole of organisation approach including its mission, vision and strategic planning. Critical success factors include: developing a co-ordinated and multidisciplinary approach to attain critical mass of research-active AH and enhance learning and development; support from senior managers demonstrated through structures, processes and systems designed to facilitate research; forming partnerships to increase collaboration and sharing of resources and knowledge; and establishing in internal framework to promote recognition for research and career path opportunities. This study identifies four key themes: whole of

  10. Influence of aging at 200 C on the corrosion resistance of Al-Li and AI-Li-Cu alloys

    1989-01-01

    This paper presents an investigation of the influence of heat treatment on the microstructure and corrosion resistance of an aluminum lithium alloy and two aluminum-lithium-copper alloys. Aging the Al-Li alloy resulted in the precipitation of δ with precipitate-free zone (PFZ) formation along the grain boundaries. The intragranular precipitation of δ did not influence either the morphology of pitting or the magnitude of the pitting potential. Pits appeared to consist of aggregates of submicron-sized cuboidal volumes. Their faceted shape suggests the strong influence of crystallographic factors. Anodic polarization of the Al-Li-Cu alloy is the T8 condition in aqueous solutions containing chloride ions resulted in blistering of the passive film and the formation of pits that were hemispherical in shape. Aging the Al-Li-Cu resulted in the precipitation of Cu-rich phases with PFZ formation along the grain and subgrain boundaries. Energy dispersive x-ray (EDX) microchemical analyses indicated the PFZ was depleted of copper. Anodic polarization of aged samples in chloride ion media resulted in localized attack along the subgrain and grain boundaries. Such attack did not occur in solutions free of chloride ions. The electrochemical tests and microchemical analyses suggest that the boundary corrosion was caused by the pitting corrosion of copper-depleted zones

    Evidence shows that factors contributing to success in physiology education for allied health students at universities include not only their high school achievement and background but also factors such as confidence with their teachers and quality of their learning experience, justifying intensive and continued survey of students' perceptions of their learning experience. Here we report data covering a 3-yr period in a physiology subject that has been redesigned for blended and online presentation. Consistent with previous reports, we show that when we undertook a blended mode of delivery, students demonstrated better grades than traditional modes of teaching; however the absence of didactic teaching in this subject resulted in lower grades overall. Students have very strong positive attitudes to weekly quizzes (80% positive approval) but report ambivalent attitudes to online self-directed learning (61% negative perception), even though they had 2-h weekly facilitated workshops. Overwhelmingly, students who undertook the subject in a self-directed online learning mode requested more face-to-face-teaching (70% of comments). From these data, we suggest that there is a quantifiable benefit to didactic teaching in the blended teaching mode that is not reproduced in online self-directed learning, even when face-to-face guided inquiry-based learning is embedded in the subject.

    The purpose of this study was to determine the perceptions and knowledge of final-year speech-language pathology (SLP), physical and occupational therapy (PT, OT) students toward stroke rehabilitation teams and the SLPs' roles on them. The investigators adapted a survey developed by (Felsher & Ross, 1994) and administered it to 35 PT, 35 OT, and 35 SLP final year students (n=105). We found that the students preferred the transdisciplinary team approach and agreed that the advantages of teamwork were the exchange of ideas, opportunities for participatory learning, and holistic treatment. Communication problems, time-consuming meetings, and role confusion were chosen as disadvantages. The students had clear perceptions of the SLP's role in aphasia, apraxia of speech, dysarthria, dysphagia, and auditory agnosia, but fewer recognized the SLP's role in alexia and memory. Some thought SLPs had a role in dressing apraxia and proprioceptive disorders. Suggestions to maximize the advantages and minimize possible disadvantages of teamwork are provided. Learners will: (1) identify the perceived advantages and disadvantages of stroke rehabilitation teamwork; (2) discover some allied health students' perceptions of the SLP's roles in stroke rehabilitation; (3) infer methods to create positive perceptions of stroke rehabilitation team members.

    Full Text Available Purpose: This paper reports the process of development of a CBR programme by UP Manila College of Allied Medical Professions, and its impact on the stakeholders: persons with disabilities, students and alumni, CBR workers, local leaders and the agencies involved in the programme.Method: The impact of the programme was assessed through interviews, questionnaires, focus group discussions and review of secondary data and records.Results: The programme results show that the condition of persons with disabilities has improved and there has been a remarkable change in their knowledge, attitudes and skills. The positive attitudes, skills and values of students were enhanced, and the CBR programme was a “character builder” for them as rehabilitation professionals. The CBR workers who participated in the programme learnt to appreciate the potential of persons with disabilities and to accept their limitations. Another key result was the pledge by local leaders to sustain CBR in their own villages.Conclusions: The students and alumni reported that the CBR programme should be replicated for nation-building. The different stakeholders reported that it helped improve the quality of life of people with disabilities and contributed to community development.DOI: 10.5463/dcid.v22i3.110

    Pentoxifylline (PTX) is a methylxanthine derivative that improves blood flow by decreasing its viscosity. Being an inhibitor of platelet aggregation, it can thus reduce the adhesiveness of cancer cells prolonging their circulation time. This delay in forming secondary tumours makes them more prone to immunological surveillance. Recently, we have evaluated its anti-metastatic efficacy against breast cancer, using MDA-MB-231 model system. In view of this, we had ascertained the effect of PTX on adhesion of MDA-MB-231 cells to extracellular matrix components (ECM) and its allied receptors such as the integrins. PTX affected adhesion of breast cancer cells to matrigel, collagen type IV, fibronectin and laminin in a dose dependent manner. Further, PTX showed a differential effect on integrin expression profile. The experimental metastasis model using NOD-SCID mice showed lesser tumour island formation when treated with PTX compared to the control. These findings further substantiate the anti-adhesive potential of PTX in breast cancer and warrant further insights into the functional regulation. Copyright © 2013 Elsevier Masson SAS.

    To evaluate the barriers and facilitators for allied health professional's participation in pressure ulcer prevention. Mixed method cohort study. Single centre study in an acute university hospital trust. Five physiotherapists and four occupational therapists were recruited from the hospital trust. Therapists had been working in the National Health Service (NHS) for a minimum of one year. Therapist views and experiences were collated using an audio recorded focus group. This recording was analysed using constant comparison analysis. Secondary outcomes included assessment of attitudes and knowledge of pressure ulcer prevention using questionnaires. Key themes surrounding barriers to participation in pressure ulcer prevention included resources (staffing and equipment), education and professional boundaries. Fewer facilitators were described, with new training opportunities and communication being highlighted. Results from the questionnaires showed the therapists had a positive attitude towards pressure ulcer prevention with a median score of 81% (range 50 to 83%). However, there were gaps in knowledge with a median score of 69% (range 50 to 77%). The therapist reported several barriers to pressure ulcer prevention and few facilitators. The primary barriers were resources, equipment and education. Attitudes and knowledge in AHPs were comparable to data previously reported from experienced nursing staff.

    Embedding online learning within higher education can provide engaging, cost-effective, interactive and flexible education. By evaluating the impact, outcomes and pedagogical influence of online cancer and education, future curricula can be shaped and delivered by higher education providers to better meet learner, health care provider and educational commissioners' requirements for enhanced patient care and service delivery needs. Using the Kirkpatrick's four-level model of educational evaluation, a systematic review of the effectiveness of online cancer education for nurses and allied health professionals was conducted. From 101 articles, 30 papers were included in the review. Educational theory is not always employed. There is an absence of longitudinal studies to examine impact; an absence of reliability and/or validity testing of measures, limited experimental designs taking account of power and few attempts to mitigate bias. There is, however, an emerging innovative use of mobile/spaced learning techniques. Evidence for clinical and educational effectiveness is weak offering insights into experiences and participant perceptions rather than concrete quantitative data and patient-reported outcomes. More pedagogical research is merited to inform effective evaluation of online cancer education, which incorporates and demonstrates a longer-term impact.

    The behavior of liquid oxygen (LOX) compatibility of aluminum lithium (Al-Li) alloys is investigated. Alloy systems of Alcoa 2090, vintages 1 to 3, and of Martin Marietta Corporation (MMC) Weldalite 049 were evaluated for their behavior related to the LOX compatibility employing liquid oxygen impact test conditions under ambient pressures and up to 1000 psi. The developments of these aluminum lithium alloys are of critical and significant interest because of their lower densities and higher specific strengths and improved mechanical properties at cryogenic temperatures. Of the different LOX impact tests carried out at the Marshall Space Flight Center (MSFC), it is seen that in certain test conditions at higher pressures, not all Al-Li alloys are LOX compatible. In case of any reactivity, it appears that lithium makes the material more sensitive at grain boundaries due to microstructural inhomogeneities and associated precipitate free zones (PFZ). The objectives were to identify and rationalize the microstructural mechanisms that could be relaxed to LOX compatibility behavior of the alloy system in consideration. The LOX compatibility behavior of Al-Li 2090 and Weldalite 049 is analyzed in detail using microstructural characterization techniques with light optical metallography, scanning electron microscopy (SEM), electron microprobe analysis, and surface studies using secondary ion mass spectrometry (SIMS), electron spectroscopy in chemical analysis (ESCA) and Auger electron spectroscopy (AES). Differences in the behavior of these aluminum lithium alloys are assessed and related to their chemistry, heat treatment conditions, and microstructural effects.

    This paper describes the development and implementation of an intervention to facilitate teamwork between general practice and outside allied and community health services and providers. A review of organizational theory and a qualitative study of 9 practices was used to design an intervention which was applied in four Divisions of General Practice and 26 urban practices. Clinical record review and qualitative interviews with participants were used to determine the key lessons from its implementation. Facilitating teamwork across organizational boundaries was very challenging. The quality of the relationship between professionals was of key importance. This was enabled by joint education and direct communication between providers. Practice nurses were key links between general practices and allied and community health services. Current arrangements for Team Care planning provide increased opportunities for access to allied health. However the current paper based system is insufficient to build relationships or effectively share roles as part of a patient care team. Facilitation is feasible but constrained by barriers to communication and trust.

    To establish a comprehensive set of recommendations for the service structure and skill set of nurses and allied healthcare professionals in prostate cancer care. Using components of formal consensus methodology, a 30-member multidisciplinary panel produced 53 items for discussion relating to the provision of care for prostate cancer patients by specialist nurses and allied healthcare professionals. Items were developed by two rounds of email correspondence in which, first, items were generated and, second, items refined to form the basis of a consensus meeting which constituted the third round of review. The fourth and final round was an email review of the consensus output. The panel agreed on 33 items that were appropriate for recommendations to be made. These items were grouped under categories of "Environment" and "Patient Pathway" and included comments on training, leadership, communication and quality assessment as well as specific items related to prostate diagnosis clinics, radical treatment clinics and follow-up survivor groups. Specialist nurses and allied healthcare professionals play a vital role alongside urologists and oncologists to provide care to men with prostate cancer and their families. We present a set of standards and consensus recommendations for the roles and skill-set required for these practitioners to provide gold-standard prostate cancer care. These recommendations could form the basis for development of comprehensive integrated prostate cancer pathways in prostate cancer centres as well as providing guidance for any units treating men with prostate cancer.

La combustion de mélanges actifs (Ti-C-Ni-An où An = Al2O3, MgO, SiC, TiB2, WC, basée sur la réaction de synthèse de TiC (ΔHf298K = −184 kJ/mole, génère des cermets complexes. Un court maintien sous charge du cermet à 1373 K, après l'explosion thermique, permet son soudage sur un substrat en acier XC55. Les cermets obtenus dans ces conditions demeurent poreux et conservent une porosité de l'ordre de 25–35 %. La densité relative du cermet, sa dureté et son comportement tribologique, dépendront de la nature de l'addition dans les mélanges de départ. Porous TiC-Ni based cermets were obtained by dispersion of carbides, oxides or borides particles in a nickel matrix thanks to the thermal explosion technique realized under a load of 20 MPa. The combustion of active mixtures (Ti-C-Ni-An where An = Al2O3, MgO, SiC, TiB2 or WC based on the titanium carbide reaction synthesis (ΔHf = −184 kJ/mol, generates porous complex cermets. After the thermal explosion, a short maintenance under load at 1373 K of the combustion product, allows at the same time the cermets welding on a carbon steel substrate. The obtained cermets under these conditions preserve a porosity of about 25–35%. The relative density, hardness and tribological behaviour of the complex cermets depend on the additions nature (An in the starting mixtures.

    There is limited published information regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) in aquaculture. Our objective was to determine the opinions of aquaculture-allied professionals around the world on the frequency of AMU and AMR in common aquatic species. The study questionnaire included five sections: respondent demographics, extent of AMU in aquaculture, frequency of observations of AMR in aquaculture, AMR monitoring and surveillance and antimicrobial susceptibility testing in various jurisdictions. It was administered in English and Spanish to 604 professionals in 25 countries and with varying expertise in aquaculture. The response rate was 33% (199/604). Over half of the participants had >10 years of experience in aquaculture: 70% (140/199) were involved in fish health/clinical work and their primary experience was with salmon, tilapia, trout, shrimp (including prawn) and/or catfish. Tetracycline use was reported by 28%, 46%, 18%, 37% and 9% of respondents working with catfish, salmon, tilapia, trout and shrimp, respectively. Resistance to tetracycline in one or more species of bacteria was reported as 'frequent-to-almost always' for the same aquaculture species by 39%, 28%, 17%, 52% and 36% of respondents, respectively. 'Frequent-to-almost always' use of quinolone was reported by 70% (32/46) and 67% (8/12) of respondents from the United States and Canada, respectively, where quinolone products are not approved for aquaculture, and extra-label fluoroquinolone use is either prohibited (United States) or discouraged (Canada). Similar frequencies of quinolone use were also reported by the majority of respondents from Europe [70% (7/10)] and Asia [90% (9/10)] where labelled indications exist. This baseline information can be used to prioritize research or surveillance for AMU and AMR in aquaculture. © 2012 Blackwell Verlag GmbH.

    Ranchi Institute of Neuro-Psychiatry and Allied Sciences (RINPAS; Ranchi Indian Mental Hospital; Ranchi Manasik Aryogyashala) traces its origin from a lunatic asylum for Indian soldiers established at Munghyr in Bihar in 1795 and thus is the first mental hospital in India established by the British purely for Indian patients as well as the second oldest functioning mental hospital in India. The hospital made great strides in improving patients care and using modern methods of assessment and treatment as well as education and research during the tenure of Dr J E Dhunjibhoy the first Indian medical superintendent. As a result the mortality rate was the lowest among the mental hospitals in Indian. There was a shift from custodial care to curative treatment. Since 1930s psychiatric training was given to undergraduate medical students of Patna Medical College and subsequently from Darbhanga and Cuttack. The Institute was affiliated to Universities of London and Edinburgh for Diploma in Psychological Medicine in 1936. The thesis work of the first Indian MD (Psychiatry) was done at this institute. Subsequently many psychiatrists completed their MD (Psychiatry) under the guidance of Dr L.P. Verma at this institute. A number of staff and alumini of the institute held the post of President and office bearers of Indian Psychiatric Society (IPS), starting with Dr J.E. Dhunjibhoy, the first president of the IPS. The Institute declined in the 1980s but after intervention of the Supreme Court it was transformed into an autonomous institute. Under the new dispensation the institution is regaining its vitality. Care and facilities for inpatients has greatly improved. Laboratory and imaging services have been updated. Modern facilities for eye and dental surgery are available. Attendance in outpatient department and especially in satellite clinics is increasing. Postgraduate training in psychiatry, clinical psychology, psychiatric social work and psychiatric nursing has started and

    Evidence-based practice (EBP) is upheld as a means for patients to receive the most efficient care in a given context. Despite the available evidence and positive beliefs about it, implementing EBP as standard daily practice still faces many obstacles. This study investigated the beliefs about and implementation of EBP among nurses and allied healthcare providers (AHP) in 9 acute care hospitals in the canton of Valais, Switzerland. A cross-sectional descriptive survey was conducted. The target population was composed of 1899 nurses and 126 AHPs. Beliefs about and implementation of EBP were measured using EBP-Beliefs and EBP-Implementation scales of Melnyk et al. The initial sample consisted in 491 participants (overall response rate 24.2%): 421 nurses (22.4% response rate) and 78 AHPs (61.9% response rate). The final sample, composed only of those who declared previous exposure to EBP, included 391 participants (329 nurses and 62 AHPs). Overall, participants had positive attitudes towards EBP and were willing to increase their knowledge to guide practice. However, they acknowledged poor implementation of EBP in daily practice. A significantly higher level of EBP implementation was declared by those formally trained in it (P = 0.006) and by those occupying more senior professional functions (P = 0.004). EBP-Belief scores predicted 13% of the variance in the EBP-Implementation scores (R 2  = 0.13). EBP is poorly implemented despite positive beliefs about it. Continuing education and support on EBP would help to ensure that patients receive the best available care based on high-quality evidence, patient needs, clinical expertise, and a fair distribution of healthcare resources. This study's results will be used to guide institutional strategy to increase the use of EBP in daily practice. © 2016 John Wiley & Sons, Ltd.

    Friction stir welded (FSW) joints of conventional precipitation-hardened aluminum alloys usually fracture in the lowest hardness zone (LHZ) during tension testing. However, all of the FSW joints of a 2198-T8 Al-Li alloy fractured in the stirred zone (SZ) instead of the LHZ with the welding parameters of 800 rpm-200 mm/min and 1600 rpm-200 mm/min under the condition that no welding defects existed in the SZ. The experiment results revealed that lazy S was not the dominant factor resulting in the unusual fracture. The SZ consisted of three subzones, i.e., the shoulder-affected zone, the pin-affected zone, and the transition zone between them. While the former two zones were characterized by fine and equiaxed recrystallized grains, incompletely dynamically recrystallized microstructure containing coarse elongated non-recrystallized grains was observed in the transition zone. The transition zone exhibited the lowest average Taylor factor in the SZ, resulting in a region that was crystallographically weak. Furthermore, obvious lithium segregation at grain boundaries was observed in the transition zone via time-of-flight secondary ion mass spectroscopy analysis, but not in the shoulder-affected zone or the pin-affected zone. The combined actions of both the two factors resulted in the appearance of preferential intergranular fracture in the transition zone and eventually caused the failure in the SZ. The lithium segregation at grain boundaries in the transition zone was closely associated with both the segregation in the base material and the partially dynamically recrystallized microstructure resulting from the inhomogeneous plastic deformation in the SZ.

    No instruments, to our knowledge, exist to assess leadership competency in existing and emerging allied health professional (AHP) leaders. This paper describes the development and preliminary exploration of the psychometric properties of a leadership competency instrument for existing and emerging AHP leaders and examines (i) its factor structure, (ii) its convergent validity with the Leadership Practices Inventory (LPI), and (iii) its discriminative validity in AHPs with different grades. During development, we included 25 items in the AHEAD (Aspiring leaders in Healthcare-Empowering individuals, Achieving excellence, Developing talents) instrument. A cross-sectional study was then conducted in 106 high-potential AHPs from Singapore General Hospital (34 men and 72 women) of different professional grades (49 principal-grade AHPs, 41 senior-grade AHPs, and 16 junior-grade AHPs) who completed both AHEAD and LPI instruments. Exploratory factor analysis was used to test the theoretical structure of AHEAD. Spearman correlation analysis was performed to evaluate the convergent validity of AHEAD with LPI. Using proportional odds regression models, we evaluated the association of grades of AHPs with AHEAD and LPI. To assess discriminative validity, the c-statistics - a measure of discrimination - were derived from these ordinal models. As theorized, factor analysis suggested a two-factor solution, where "skills" and "values" formed separate factors. Internal consistency of AHEAD was excellent (α-values > 0.88). Total and component AHEAD and LPI scores correlated moderately (Spearman ρ-values, 0.37 to 0.58). The c-index for discriminating between AHP grades was higher for AHEAD than for the LPI (0.76 vs. 0.65). The factorial structure of AHEAD was generally supported in our study. AHEAD showed convergent validity with the LPI and outperformed the LPI in terms of discriminative validity. These results provide initial evidence for the use of AHEAD to assess leadership

    There is an increasing presence of patient-led social media, mobile apps and patient support technology, but little is known about the role of these in the support of bariatric surgery patients in the UK. This study aimed to seek the views of allied health professionals (AHPs) working in bariatric surgical teams to understand their current perceptions of the role of social media, mobile apps and patient-support technology within bariatric surgery in the UK. A confidential, printed survey was distributed to the AHPs at the British Obesity and Metabolic Surgery Society (BOMSS) 7th Annual Scientific Conference in January 2016. An email to AHPs who did not attend the conference was sent requesting voluntary participation in the same survey online through Survey Monkey® within 2 weeks of the conference. A total of 95 responses were received, which was a 71% response rate (n = 134). Responses were from nurses (34%, n = 46), dietitians (32%, n = 32), psychologists (16%, n = 12) and 1 nutritionist, 1 physiotherapist, 1 patient advocate, 1 surgeon and 9 respondents did not fill in their title. The use of social media and mobile apps by patients is increasing, with AHPs concerned about misinformation; advice may differ from what is given in clinic. Technologies, e.g. telehealth and videoconferencing are not widely used in bariatric surgery in the UK. AHPs are unclear about the role of technologies for bariatric surgical patient support. Further discussions are needed to understand the potential of technology with AHPs supporting/facilitating patients as this becomes more commonplace.

Dans le cadre de ce travail, le choix du laser s'est porte sur un laser nano-impulsionnel a fibre dopee ytterbium dont les caracteristiques permettent la fusion quasiinstantanee sur quelques microns de la surface traitee, immediatement suivie d'une solidification ultra-rapide avec des vitesses de refroidissement pouvant atteindre 1011 K/s. La combinaison de ces processus favorise l'elimination des defauts surfaciques, la formation de phases hors equilibre, la segregation d'elements chimiques et la formation d'une nouvelle couche d'oxyde dont les proprietes sont gouvernees par les parametres laser. Afin de les correler avec la reactivite electrochimique de la surface, l'influence de deux parametres laser sur les proprietes physicochimiques de la surface a ete etudiee: la puissance du laser et le taux de recouvrement des impacts laser. Pour clarifier ces relations, la resistance a la corrosion par piquration des surfaces traitees a ete determinee par des tests electrochimiques. Pour des parametres laser specifiques, le potentiel de piquration d'un acier inoxydable de type 304L augmente de plus de 500 mV traduisant ainsi une meilleure tenue a la corrosion localisee en milieu chlorure.

    Recruitment and retention of allied health professionals (AHPs) to remote and rural Australia is challenging and correlates with poorer health status of remote and rural residents. While much has been written about the recruitment and retention problem, this study took a new approach by reviewing the literature describing the motivation of AHPs to work in remote and rural areas and then analyzing the findings from the perspective of motivation theory using Herzberg's extrinsic and intrinsic classification. Intrinsic motivation incentives are known to contribute to job satisfaction and come from within the individual, for example the pleasure derived from autonomy or challenge at work. In contrast, extrinsic motivation incentives are provided by the job and include such factors as salary and professional development provisions. Extrinsic incentives are important because they prevent job dissatisfaction. Job satisfaction has been shown to be linked with increased retention. Thirty-five articles, including 26 from Australia, met the inclusion criteria. The key findings related to motivation from each article are outlined and the results classified into the extrinsic-intrinsic framework. The incentives are then further analyzed as having a positive or a negative influence. In total, 38 different incentives were described a total of 246 times. Of the total, almost half (n=115) comprised extrinsic incentives with a negative influence, with poor access to professional development, professional isolation and insufficient supervision the most frequently reported. Rural lifestyle and diverse caseloads were the most frequently mentioned positive extrinsic incentives, while autonomy and community connectedness were the most cited positive intrinsic incentives. Negative intrinsic incentives were mentioned least frequently (n=18); however, of these, feeling overwhelmed and that your work was not valued by the community were the most commonly reported. The results demonstrate the

    Objective Delegation and skill sharing are emerging service strategies for allied health (AH) professionals working in Queensland regional cancer care services. The aim of the present study was to describe the consistency between two services for the types and frequency of tasks provided and the agreement between teams in the decision to delegate or skill share clinical tasks, thereby determining the potential applicability to other services. Methods Datasets provided by two similar services were collated. Descriptive statistical analyses were used to assess the extent of agreement. Results In all, 214 tasks were identified as being undertaken by the services (92% agreement). Across the services, 70 tasks were identified as high frequency (equal to or more frequently than weekly) and 29 as not high frequency (46% agreement). Of the 68 tasks that were risk assessed, agreement was 66% for delegation and 60% for skill sharing, with high-frequency and intervention tasks more likely to be delegated. Conclusions Strong consistency was apparent for the clinical tasks undertaken by the two cancer care AH teams, with moderate agreement for the frequency of tasks performed. The proportion of tasks considered appropriate for skill sharing and/or delegation was similar, although variation at the task level was apparent. Further research is warranted to examine the range of factors that affect the decision to skill share or delegate. What is known about the topic? There is limited research evidence regarding the use of skill sharing and delegation service models for AH in cancer care services. In particular, the extent to which decisions about task safety and appropriateness for delegation or skill sharing can be generalised across services has not been investigated. What does this paper add? This study investigated the level of clinical task consistency between two similar AH cancer care teams in regional centres. It also examined the level of agreement with regard to

    This study explored how classroom teachers, allied health professionals, students with cerebral palsy, and their parents view high-tech assistive technology service delivery in the classroom. Semi-structured interviews with six classroom teachers and six parents and their children were conducted. Additionally, two focus groups comprising 10 occupational therapists and six speech pathologists were carried out. Ethical and confidentiality considerations meant that the groups were not matched. Results revealed that it is often untrained staff member who determine students' educational needs. The participants' experiences suggested that, particularly in mainstream settings, there is a need for support and guidance from a professional with knowledge of assistive technology who can also take a lead and guide classroom teachers in how to meet students' needs. Students' motivation to use the technology was also found to be critical for its successful uptake. The study points to the need for classroom teachers to be given sufficient time and skill development opportunities to enable them to work effectively with assistive technology in the classroom. The participants' experiences suggest that such opportunities are not generally forthcoming. Only in this way can it be ensured that students with disabilities receive the education that is their right. Implications for Rehabilitation Classroom teachers, allied health professionals, students, parents need ongoing support and opportunities to practise operational, strategic and linguistic skills with the assistive technology equipment. System barriers to the uptake of assistive technology need to be addressed. To address the lack of time available for training, programing and other support activities around assistive technology, dedicated administrative support is crucial. Professional development around the use of the quality low cost ICF-CY checklist is recommended for both school and allied health staff.

    This paper outlines current challenges facing healthcare providers and education providers in trying to ensure Allied Health Professionals (AHPs) are fit for practice, in a climate driven by financial constraints and service improvement directives from the Department of Health (DH). Research was undertaken in 2009 to investigate the current provision of Continuing Professional Development (CPD) in the southwest region of England. The purpose was to define exactly what problems existed with this provision, and to propose changes which could be implemented in order to ensure that the provision meets the needs of stakeholders in future years.

    Research evidence suggests that journal clubs (JCs) are one approach which can be used to bridge the gap between research and clinical practice. However, there are issues which potentially threaten their viability such as on-going participation or compliance with attendance, which require further exploration. The objectives of this study are: to explore the views and perspectives of allied health practitioners (AHPs) regarding the use of any type of JC in promoting evidence-based practice (EBP); to identify ways in which an innovative model of JC developed by the International Centre for Allied Health Evidence (iCAHE) might be refined. A qualitative descriptive study utilising focus group interviews with various groups of AHP was undertaken-- those who have been exposed to the iCAHE JC model and those who have no experience of the iCAHE model (although they may have had exposure to other forms of JC). Maximum variation sampling was used to recruit participants for the study. Transcripts of focus groups were coded and distilled into content-related categories. Six focus groups with 39 AHPs were facilitated. Allied health practitioners perspectives' on JCs were classified in five broad categories: utility and benefits of a JC, elements of an effective and sustainable JC, barriers to participation, incentives for participation, and opportunities for improvement in the current iCAHE JC model. Overall, JCs were seen as a forum for reflective practice and keeping up-to-date with research evidence, and a venue for learning the processes involved in critical appraisal. Limited knowledge of statistics and heavy clinical workload were reported as barriers to participation in a JC. Strategies such as mentoring, strong support from managers, and providing CPD (continuing professional development) points can potentially address these barriers. Opportunities for refinement of the current iCAHE model were raised. This study suggests that a structured model of JC such as i

    The influence of tuning the laser pulse energy during the analyses on the resulting microstructure in a specimen utilizing an ultra-fast laser assisted atom probe was demonstrated by a case study of a binary Al-Li alloy. The decomposition parameters, such as the size, number density, volume fraction, and composition of δ\\' precipitates, were carefully monitored after each analysis. A simple model was employed to estimate the corresponding specimen temperature for each value of the laser energy. The results indicated that the corresponding temperatures for the laser pulse energy in the range of 10 to 80 pJ are located inside the miscibility gap of the binary Al-Li phase diagram and fall into the metastable equilibrium field. In addition, the corresponding temperature for a laser pulse energy of 100 pJ was in fairly good agreement with reported range of δ\\' solvus temperature, suggesting a result of reversion upon heating due to laser pulsing. © 2016 Wiley Periodicals, Inc.

    Evidence-based practice (EBP) is fundamental to improving patient outcomes. Factors affecting EBP capabilities are linked with institutional culture and barriers, personal self-belief, and individual ability. To effect change in capabilities, interventions must target barriers and be informed by behaviour change theory. This study measured the effect of training and organisational change on EBP measures amongst allied health professionals. All allied health staff (n=196) employed across the Mater Health Services (Brisbane, Queensland) were invited to complete a survey assessing EBP self-efficacy, outcome expectancy and use, as well as EBP training undertaken. Data were compared with those of surveys from 2010 and 2011. Response rate was 70.9% (n=139/196); 32 staff completed all surveys. Significant improvements were observed in staff undertaking training (EBP, p=0.008; research design and analysis, p=0.003) since the first survey. The significant increase in EBP self-efficacy that occurred from T1 to T2 remained at T3 (p=0.008). Fewer between-department differences were observed over time. This study identified sustained EBP self-efficacy improvements in this cohort and found that between-department differences have virtually disappeared. Ongoing interventions are required to sustain and improve staff's belief in their ability to deliver EBP.

    The objective was to identify a selection of the best examples of the public health contributions by Allied Health Professionals (AHPs) in order to encourage a wider awareness and participation from that workforce to public health practice. A mapping exercise was used to identify evidence-based interventions that could lead to health improvements across a population. A rapid review was undertaken to identify evidence, followed by a survey of Allied Health Profession (AHP) practitioners and an expert panel consensus method to select the examples of AHP public health interventions. Nine evidence-based interventions are identified and selected as examples of current AHP good practice. These examples represent a contribution to public health and include screening interventions, secondary prevention and risk management. This study contributes to a strategy for AHPs in public health by appraising the effectiveness and impact of some exemplar AHP practices that contribute to health improvement. There is a need for AHPs to measure the impact of their interventions and to demonstrate evidence of outcomes at population level. © The Author 2016.

    In order to improve manufacturing efficiency and reduce structural mass and costs in the production of launch vehicle structures, NASA is pursuing a wide-range of innovative, near-net shape manufacturing technologies. A technology that combines friction stir welding (FSW) and spin-forming has been applied to manufacture a single-piece crew module using Aluminum-Lithium (AL-Li) Alloy 2195. Plate size limitations for Al-Li alloy 2195 require that two plates be FSW together to produce a spin-forming blank of sufficient size to form the crew module. Subsequent forming of the FSW results in abnormal grain growth (AGG) within the weld region upon solution heat treatment (SHT), which detrimentally impacts strength, ductility, and fracture toughness. The current study seeks to identify microstructural factors that contribute to the development of AGG. Electron backscatter diffraction (EBSD) was used to correlate driving forces for AGG, such as stored energy, texture, and grain size distributions, with the propensity for AGG. Additionally, developmental annealing treatments prior to SHT are examined to reduce or eliminate the occurrence of AGG by promoting continuous, or uniform, grain growth

    Tanzania requires more health professionals equipped to tackle its serious health challenges. When it became an independent university in 2007, Muhimbili University of Health and Allied Sciences (MUHAS) decided to transform its educational offerings to ensure its students practice competently and contribute to improving population health. In 2008, in collaboration with the University of California San Francisco (UCSF), all MUHAS's schools (dentistry, medicine, nursing, pharmacy, and public health and social sciences) and institutes (traditional medicine and allied health sciences) began a university-wide process to revise curricula. Adopting university-wide committee structures, procedures, and a common schedule, MUHAS faculty set out to: (i) identify specific competencies for students to achieve by graduation (in eight domains, six that are inter-professional, hence consistent across schools); (ii) engage stakeholders to understand adequacies and inadequacies of current curricula; and (iii) restructure and revise curricula introducing competencies. The Tanzania Commission for Universities accredited the curricula in September 2011, and faculty started implementation with first-year students in October 2011. We learned that curricular revision of this magnitude requires: a compelling directive for change, designated leadership, resource mobilization inclusion of all stakeholders, clear guiding principles, an iterative plan linking flexible timetables to phases for curriculum development, engagement in skills training for the cultivation of future leaders, and extensive communication.

    Full Text Available Objective: To describe telehealth interventions delivered by allied health professionals and nurses in rural and remote areas, and to compare the effects of telehealth interventions with standard face-to-face interventions. Data sources: CINAHL, Embase, PsycINFO and PubMed databases were searched. The content of relevant journals and published articles were also searched. Study selection: Studies examining the effectiveness of allied health and nursing telehealth interventions for rural and remote populations were included in descriptive analyses. Studies comparing telehealth intervention with standard face-to-face interventions grouped by type of intervention approach were used to examine between-groups effect sizes. Data extraction: Methodological quality of studies was rated using the QualSyst critical appraisal tool and the National Health and Medical Research Council (NHMRC Evidence Hierarchy levels. Data synthesis: After quality ratings, 43 studies were included. A majority of studies had strong methodological quality. The disciplines of psychology and nursing were represented most frequently, as were studies using a cognitive intervention approach. Meta-analysis results slightly favoured telehealth interventions compared with face-to-face interventions, but did not show significant differences. Interventions using a combined physical and cognitive approach appeared to be more effective. Conclusion: Telehealth services may be as effective as face-to-face interventions, which is encouraging given the potential benefits of telehealth in rural and remote areas with regards to healthcare access and time and cost savings.

    Health sciences programs are being designed to attract students who are likely to stay and practice in rural and northern Canada. Consequently, student recruitment and screening are increasingly including assessment of suitability for rural practice. Although retention factors among rural physicians and nurses have been investigated, little is known about factors that contribute to the retention of other healthcare professionals who work in rural areas. The primary objective of this project was to identify the personal characteristics and experiences of allied health professionals who have worked long term in northern British Columbia (BC), Canada. The study used a qualitative descriptive approach. Six speech language pathologists, four psychologists, four occupational therapists, eight social workers, and four physiotherapists practicing long term in northern BC were recruited, using a convenience sample and the snowball technique, to participate in semi-structured telephone interviews. The interviews were audiotaped and transcribed verbatim. A thematic content analysis identified the motivations for their decision to begin or stay working in northern communities, the reasons for choosing rural or northern education and key themes concerning personal characteristics and experiences. A process of member checking and an external audit validated the analysis and findings. There were two major themes for choosing rural and northern education. For some, selection of rural or northern training was based on accessibility to health education programs; all participants who chose rural and northern education had already decided that they were going to practice rurally. Generally, participants identified past positive experiences and rural background as influencing their practice location decision. Participants named the community's need for healthcare professionals, career advancement opportunities, welcoming employers, peer support, as well as promises of continuing

    Cancer survival is increasing as patients live longer with a cancer diagnosis. This success has implications for health service provision in that increasing numbers of adults who have received cancer therapy are requiring monitoring and long-term health care by a wide range of practitioners. Given these recent trends there is a need to explore staff perceptions and confidence in managing the consequences of cancer diagnosis and treatment in cancer survivors to enhance an integrated cancer service delivery. This study examines the self-reported perceptions of competence in nurses and professionals allied to medicine providing survivorship services caring for adults after cancer treatment in both secondary and primary care. A cross sectional survey of the adult cancer workforce using a self-assessment tool for assessing confidence in providing long-term cancer patient management. This study was a health service evaluation. The study was conducted within the United Kingdom. Respondents were 618 health care professionals of these 368 were specialist adult cancer nurses in oncology and the community setting and 250 cancer allied health professionals. The survey tool was developed with experts in cancer management, nurses professionals allied to medicine such as physiotherapists and dieticians, educationalists, patient groups as well as health service managers. Competence was assessed in 4 domains clinical practice, symptom management, care co-ordination and proactive management. Perceptions of training needs were also ascertained. Data were collected using an Internet survey distributed through cancer services, community settings and professional institutions. In total 618 practitioners who responded were providing services for adults' 1-year post cancer therapy. Practitioners felt confident in managing psychosocial care and communicating with patients. Deficits in self-reported confidence were found in long-term medications management, care planning, long-term and

    Jonas Schneider tackles a question that is of great interest both to scholars of nuclear proliferation and to practitioners of nonproliferation diplomacy: Why do some political leaders of U.S. allies agree to abandon their nation's nuclear weapons activities, while others - who are often members of the same allied government and sometimes even of the same political party - steadfastly reject such a course reversal? Our existing stock of theories does not fare well in accounting for this important variation in leaders' attitudes. To solve this puzzle, Schneider develops an innovative theory that draws on the individual status conceptions of allied political leaders. Subsequently, the author undertakes to test his theory using four thoroughly researched case studies, and he derives important lessons for international nonproliferation diplomacy toward the Middle East and Northeast Asia.

    Employees in health care service are at high risk for developing mental health complaints. The effects of mental health complaints on work can have serious consequences for the quality of care provided by these workers. To help health service workers remain healthy and productive, preventive actions are necessary. A Workers' Health Surveillance (WHS) mental module may be an effective strategy to monitor and promote good (mental) health and work performance. The objective of this paper is to describe the design of a three arm cluster randomized controlled trial on the effectiveness of a WHS mental module for nurses and allied health professionals. Two strategies for this WHS mental module will be compared along with data from a control group. Additionally, the cost effectiveness of the approaches will be evaluated from a societal perspective. The study is designed as a cluster randomized controlled trial consisting of three arms (two intervention groups, 1 control group) with randomization at ward level. The study population consists of 86 departments in one Dutch academic medical center with a total of 1731 nurses and allied health professionals. At baseline, after three months and after six months of follow-up, outcomes will be assessed by online questionnaires. In both intervention arms, participants will complete a screening to detect problems in mental health and work functioning and receive feedback on their screening results. In cases of impairments in mental health or work functioning in the first intervention arm, a consultation with an occupational physician will be offered. The second intervention arm offers a choice of self-help e-mental health interventions, which will be tailored based on each individual's mental health state and work functioning. The primary outcomes will be help-seeking behavior and work functioning. Secondary outcomes will be mental health and wellbeing. Furthermore, cost-effectiveness in both intervention arms will be assessed, and

    White-nose syndrome (WNS) of bats, caused by the fungus previously known as Geomyces destructans, has decimated populations of insectivorous bats in eastern North America. Recent work on fungi associated with bat hibernacula uncovered a large number of species of Geomyces and allies, far exceeding the number of described species. Communication about these species has been hindered by the lack of a modern taxonomic evaluation, and a phylogenetic framework of the group is needed to understand the origin of G. destructans and to target closely related species and their genomes for the purposes of understanding mechanisms of pathogenicity. We addressed these issues by generating DNA sequence data for the internal transcribed spacer (ITS) region, nuclear large subunit (LSU) rDNA, MCM7, RPB2, and TEF1 from a diverse array of Geomyces and allies that included isolates recovered from bat hibernacula as well as those that represent important type species. Phylogenetic analyses indicate Geomyces and allies should be classified in the family Pseudeurotiaceae, and the genera Geomyces, Gymnostellatospora, and Pseudogymnoascus should be recognized as distinct. True Geomyces are restricted to a basal lineage based on phylogenetic placement of the type species, Geomyces auratus. Thus, G. destructans is placed in genus Pseudogymnoascus. The closest relatives of Pseudogymnoascus destructans are members of the Pseudogymnoascus roseus species complex, however, the isolated and long branch of P. destructans indicates that none of the species included in this study are closely related, thus providing further support to the hypothesis that this pathogen is non-native and invasive in eastern North America. Several conidia-producing isolates from bat hibernacula previously identified as members of Pseudeurotium are determined to belong to the genus Leuconeurospora, which is widespread, especially in colder regions. Teberdinia hygrophila is transferred to Pseudeurotium as Pseudeurotium

    Team-based approaches to research capacity building (RCB) may be an efficient means to promote allied health research participation and activity. In order to tailor such interventions, a clearer understanding of current patterns of research participation within allied health teams is needed. Different self-report measures exist which evaluate a team's research capacity and participation, as well as associated barriers and motivators. However, it remains unclear how such measures are associated with a team's actual research activity (e.g., journal publications, funding received). In response, this observational study aimed to identify the research activity, self-reported success, and motivations and barriers to undertaking research of eight allied health professional (AHP) teams and to explore whether any relationships exist between the self-reported measures and actual research activity within each team. A total of 95 AHPs from eight teams completed the research capacity and culture survey to evaluate team success, barriers and motivators to undertaking research, and an audit of research activity from January 2013 to August 2014 was undertaken within each team. Kendell's correlation coefficients were used to determine the association between research activity (i.e., number of journal publications, ethically approved projects and funding received) and the self-reported measures. Seven out of eight teams rated their teams as having average success in research and demonstrated some form of research activity including at least two ethically approved projects. Research activity varied between teams, with funding received ranging from $0 to over $100,000, and half the teams not producing any journal publications. Team motivators demonstrated a stronger association with research activity compared to barriers, with the motivator "enhancing team credibility" being significantly associated with funding received. No significant association between self-reported research

    Mycophilic fungi of anamorphic genus Sepedonium (telomorphs in Hypomyces, Hypocreales, Ascomycota) infect and parasitize sporomata of boletes. The obligated hosts such as Boletus edulis and allied species (known as "porcini mushrooms") are among the most valued and prized edible wild mushrooms in the world. Sepedonium infections have a great morphological variability: at the initial state, contaminated mushrooms present a white coating covering tubes and pores; at the final state, Sepedonium forms a deep and thick hyphal layer that eventually leads to the total necrosis of the host. Up to date, Sepedonium infections in porcini mushrooms have been evaluated only through macroscopic and microscopic visual analysis. In this study, in order to implement the infection evaluation as a routine methodology for industrial purposes, the potential application of Hyperspectral Imaging (HSI) and Principal Component Analysis (PCA) for detection of Sepedonium presence on sliced and dried B. edulis and allied species was investigated. Hyperspectral images were obtained using a pushbroom line-scanning HSI instrument, operating in the wavelength range between 400 and 1000 nm with 5 nm resolution. PCA was applied on normal and contaminated samples. To reduce the spectral variability caused by factors unrelated to Sepedonium infection, such as scattering effects and differences in sample height, different spectral pre-treatments were applied. A supervised rule was then developed to assign spectra recorded on new test samples to each of the two classes, based on the PC scores. This allowed to visualize directly - within false-color images of test samples - which points of the samples were contaminated. The results achieved may lead to the development of a non-destructive monitoring system for a rapid on-line screening of contaminated mushrooms. Copyright © 2015 Elsevier B.V. All rights reserved.

    Exercise can be prescribed to prevent, manage, and treat many leading non-communicable diseases (NCDs) and underlying risk factors. However, surprisingly, Australia is one of only a few countries where allied healthcare professionals with specialized university education and training in exercise prescription and delivery provide services within a government-run healthcare system (Medicare). This article presents data on Medicare-funded services provided by accredited exercise physiologists (AEPs) from the inclusion of the profession in the allied healthcare model (January, 2006) to the end of 2012. We conceptualize these data in relation to current NCD trends, and outline recommendations that can potentially help curtail the current chronic disease burden through the further integration of exercise professionals into the healthcare system in Australia, and internationally. From 2006 to 2012, the number of AEPs in Australia has increased 563 %. This rise in AEPs has been paralleled by increased delivery of services for eligible patients with a chronic medical condition (+614 %), type 2 diabetes mellitus (+211 to 230 %), and of Aboriginal and Torres Strait Islander descent (+343 %). These trends, which were developed through the "early years" of the profession, are encouraging and suggest that AEPs have taken up a vital position within the healthcare system. However, the total number of services provided by AEPs currently remains very low in relation to the prevalence of overweight-obesity and type 2 diabetes in Australia. Furthermore, services for Aboriginal Australians are very low considering the extreme burden of chronic diseases in these vulnerable populations. We provide some recommendations that may help the exercise physiology profession play a greater role in tackling the NCD burden and shift the healthcare model in a direction that is more proactive and focused on disease prevention and health, including the early identification and treatment of major

    Full Text Available Abstract Background The health workforce in Australia is ageing, particularly in rural areas, where this change will have the most immediate implications for health care delivery and workforce needs. In rural areas, the sustainability of health services will be dependent upon nurses and allied health workers being willing to work beyond middle age, yet the particular challenges for older health workers in rural Australia are not well known. The purpose of this research was to identify aspects of work that have become more difficult for rural health workers as they have become older; and the age-related changes and exacerbating factors that contribute to these difficulties. Findings will support efforts to make workplaces more 'user-friendly' for older health workers. Methods Nurses and allied health workers aged 50 years and over were invited to attend one of six local workshops held in the Hunter New England region of NSW, Australia. This qualitative action research project used a focus group methodology and thematic content analysis to identify and interpret issues arising from workshop discussions. Results Eighty older health workers from a range of disciplines attended the workshops. Tasks and aspects of work that have become more difficult for older health workers in hospital settings, include reading labels and administering medications; hearing patients and colleagues; manual handling; particular movements and postures; shift work; delivery of babies; patient exercises and suturing. In community settings, difficulties relate to vehicle use and home visiting. Significant issues across settings include ongoing education, work with computers and general fatigue. Wider personal challenges include coping with change, balancing work-life commitments, dealing with attachments and meeting goals and expectations.

    A previous report has described how iodine 131 can be prepared from elementary tellurium by a dry method which consists in treating irradiated tellurium at 400 degrees in argon. The possibility of carrying out this treatment in a stainless steel or alumina apparatus has been considered. The behavior of gaseous iodine 131 towards these materials has thus been studied. If the adsorption of iodine on stainless steel is superficial desorption is rapid at 250 degrees in oxygen or 400 degrees in argon. If the adsorption is chemical in nature it becomes necessary to heat to higher temperatures. Adsorption of iodine on alumina is very weak and the iodine can be desorbed rapidly. With these materials tests have been carried out on 300 gms of tellurium containing 41 curies of iodine 131; the yields were very satisfactory ( 98 per cent).

    Effects of aging on the localized and stress corrosion of AlLi 2090 alloy were investigated by measuring relevant critical potentials using cyclic polarization test and constant extention rate test (CERT) in a deaerated 3.5% NaCl solution at 30 .deg. C. The resistance to localized corrosion, when evaluated in terms of the film breakdown potential (E b ) and repassivation potential (E rp ) from cyclic polarization curve measured potentiodynamically, decreased with aging. Pitting corrosion initiated at Al-Fe-Cu particles, which was confirmed by the enrichment of Fe and Cu inside of pit. Stress corrosion cracking of 2090 alloy aged did not occur under freely corroding condition when load applied in longitudinal transverse direction. The susceptibility to SCC of the alloy, however, was very sensitive to applied potentials. At applied potentials above E b , the SCC susceptibility increased with applied potential. On the other hand, at potentials below E rp , the SCC susceptibility decreased with decreasing the applied potential. The critical cracking potential (E cc ) of aged 2090 alloy was found to exist between E b and E rp when SCC was assumed to occur at the strain to failure ratio (ε NaCl /ε air ) lower than 0.8. The resistance to SCC decreased in the order of underaging, peak aging and overaging, that is, with aging. The cracking mechanism of the alloy was well explained by the active path mechanism

    Highlights: • Corrosion inhibition of carbon steel and of copper by the amino acids was studied. • Inhibition efficiencies were experimentally achieved by electrochemical impedance. • DFT and Monte Carlo methods allowed correlating molecular properties with inhibition efficiency. • The corrosion inhibition followed the electron donation the electron-back donations process. - Abstract: Six amino acids were evaluated as corrosion inhibitors for carbon steel and copper in 0.5 mol L"−"1 H_2SO_4 solution by potentiodynamic polarization and electrochemical impedance techniques allied to Density Functional Theory (DFT) and Monte Carlo computations The corrosion inhibitor rankings were: Arg > Gln > Asn > Met > Cys > Ser, for copper, and Met > Cys > Ser > Arg > Gln > Asn, for carbon steel. The DFT approach failed to explain the corrosion inhibition rating based on the HOMO and LUMO energies of the isolated amino acid molecules, while the simpler classical Monte Carlo approach, performed considering the interaction energies between the corrosion inhibitor and the metallic substrate, was successful.

Nurses and AHPs delivering self-management require clear guidance, training in the use of effective self-management skills, and education that challenges their preconceptions regarding patients. The design of health care services also needs to consider the practical barriers to COPD self-management support for the implementation of such interventions to be successful.

    The genetic differentiation and structure of Hibiscus tiliaceus, a pantropical plant with sea-drifted seeds, and four allied species were studied using six microsatellite markers. A low level of genetic differentiation was observed among H. tiliaceus populations in the Pacific and Indian Ocean regions, similar to the results of a previous chloroplast DNA (cpDNA) study. Frequent gene flow by long-distance seed dispersal is responsible for species integration of H. tiliaceus in the wide distribution range. On the other hand, highly differentiated populations of H. tiliaceus were detected in West Africa, as well as of Hibiscus pernambucensis in southern Brazil. In the former populations, the African continent may be a geographical barrier that prevents gene flow by sea-drifted seeds. In the latter populations, although there are no known land barriers, the bifurcating South Equatorial Current at the north-eastern horn of Brazil can be a potential barrier to gene flow and may promote the genetic differentiation of these populations. Our results also suggest clear species segregation between H. tiliaceus and H. pernambucensis, which confirms the introgression scenario between these two species that was suggested by a previous cpDNA study. Our results also provide good evidence for recent transatlantic long-distance seed dispersal by sea current. Despite the distinct geographical structure observed in the cpDNA haplotypes, a low level of genetic differentiation was found between Pacific and Atlantic populations of H. pernambucensis, which could be caused by transisthmian gene flow.

A cross-sectional survey was conducted using an online questionnaire. Rural western NSW. AHPs including physiotherapists, speech pathologists, occupational therapists and psychologists ('therapists') working with people with disabilities. AHPs characteristics. The majority of respondents were women (94%), with a mean age of 39 years; average time since qualification was 14 years; mean years in current position was 6. Most worked with people with a lifelong disability. Two thirds reported that family ties kept them in rural areas; 71% grew up in a rural/remote area. Most participants (94%) enjoyed the rural lifestyle, and 84% reported opportunities for social interaction as good or very good. Participants with dependent children were less likely to cease working in western NSW within 5 years than those without dependent children (P working with people with disabilities in rural NSW were identified. Overall working, but also social conditions and community attachment were important for this group.

    Full Text Available Context: Caregivers of sick children have to be careful with medicine dosing and giving medicines to a reluctant child can be challenging. Aim: To assess the knowledge, attitude, and practices of caregivers regarding pediatric medicine administration and health literacy allied to this task. Settings and Design: This cross-sectional study was carried out on outpatient and inpatient basis in the pediatrics department of a teaching hospital over 6 months. Subjects and Methods: Data regarding sociodemographic profile of patient and caregiver, idea regarding pediatric dosage forms, dosing of medicines, and medication errors during administration were recorded from 377 caregivers. Reconstitution of dry powder and measurement of 5 mL liquid medicine using measuring cup of the medicine phial was demonstrated by the caregivers. Statistical Analysis: Association assessed by point biserial correlation and Spearman's rank correlation. Results: Majority of the primary caregivers surveyed were young, educated, homemaker mothers. Liquid medicines were used maximally (88.9%. Majority (87.3% of the caregivers used standardized dosing instruments to measure liquids and reconstitution (85.9%, and teaspoon measurement task (91% was performed satisfactorily by most. Some potentially wrong practices (e.g., adding medicine to milk, redilution of reconstituted medicine, and storing beyond the recommended period were recorded. Medication errors were reported by 44.5% caregivers, significantly more in the outpatient setting. Although the statistical correlation was weak, the chance of medication error was less, and the precision of measurement was better with increasing education of the caregiver. Conclusions: Physicians need to be aware of the limitations of knowledge and the possibility of wrong administration practices among caregivers of children. Remedial measures in this regard can reduce the risk of medication errors.

    1.4 mm 2A97 Al-Li alloy thin sheets were welded by friction stir lap welding using the stirring tools with different pin length at different rotational speeds. The influence of pin length and rotational speed on the defect features and mechanical properties of lap joints were investigated in detail. Microstructure observation shows that the hook defect geometry and size mainly varies with the pin length instead of the rotational speed. The size of hook defects on both the advancing side (AS) and the retreating side (RS) increased with increasing the pin length, leading to the effective sheet thickness decreased accordingly. Electron backscatter diffraction analysis reveals that the weld zones, especially the nugget zone (NZ), have the much lower texture intensity than the base metal. Some new texture components are formed in the thermo-mechanical affected zone (TMAZ) and the NZ of joint. Lap shear test results show that the failure load of joints generally decreases with increasing the pin length and the rotational speed. The joints failed during the lap shear tests at three locations: the lap interface, the RS of the top sheet and the AS of the bottom sheet. The fracture locations are mainly determined by the hook defects. - Highlights: • Hook defect size mainly varies with the pin length of stirring tool. • The proportion of LAGBs and substructured grains increases from NZ to TMAZ. • Weld zones, especially the NZ, have the much lower texture intensity than the BM. • Lap shear failure load and fracture location of joints is relative to the hook defects.

    Full Text Available Radar remote sensing has demonstrated its applicability to the retrieval of basin-scale soil moisture. The mechanism of radar backscattering from soils is complicated and strongly influenced by surface roughness. Additionally, retrieval of soil moisture using AIEM (advanced integrated equation model-like models is a classic example of underdetermined problem due to a lack of credible known soil roughness distributions at a regional scale. Characterization of this roughness is therefore crucial for an accurate derivation of soil moisture based on backscattering models. This study aims to simultaneously obtain surface roughness parameters (standard deviation of surface height σ and correlation length cl along with soil moisture from multi-angular ASAR images by using a two-step retrieval scheme based on the AIEM. The method firstly used a semi-empirical relationship that relates the roughness slope, Zs (Zs = σ2/cl and the difference in backscattering coefficient (Δσ from two ASAR images acquired with different incidence angles. Meanwhile, by using an experimental statistical relationship between σ and cl, both these parameters can be estimated. Then, the deduced roughness parameters were used for the retrieval of soil moisture in association with the AIEM. An evaluation of the proposed method was performed in an experimental area in the middle stream of the Heihe River Basin, where the Watershed Allied Telemetry Experimental Research (WATER was taken place. It is demonstrated that the proposed method is feasible to achieve reliable estimation of soil water content. The key challenge is the presence of vegetation cover, which significantly impacts the estimates of surface roughness and soil moisture.

    A recent approach to colon cancer therapy is to employ selective drugs with specific extra/intracellular sites of action. Alteration of cytoskeletal protein reorganization and, subsequently, to cellular biomechanical behaviour during cancer progression highly affects the cancer cell progress. Hence, cytoskeleton targeted drugs are an important class of cancer therapy agents. We have studied viscoelastic alteration of the human colon adenocarcinoma cell line, SW48, after treatment with a drug delivery system comprising chitosan as the carrier and albendazole as the microtubule-targeting agent (MTA). For the first time, we have evaluated the biomechanical characteristics of the cell line, using the micropipette aspiration (MA) method after treatment with drug delivery systems. Surprisingly, employing a chitosan-albendazole pair, in comparison with both neat materials, resulted in more significant change in the viscoelastic parameters of cells, including the elastic constants (K 1 and K 2 ) and the coefficient of viscosity (μ). This difference was more pronounced for cancer cells after 48h of the treatment. Microtubule and actin microfilament (F-actin) contents in the cell line were studied by immunofluorescent staining. Good agreement was observed between the mechanical characteristics results and microtubule/F-actin contents of the treated SW48 cell line, which declined after treatment. The results showed that chitosan affected F-actin more, while MTA was more effective for microtubules. Toxicity studies were performed against two cancer cell lines (SW48 and MCF10CA1h) and compared to normal cells, MCF10A. The results showed cancer selectiveness, safety of formulation, and enhanced anticancer efficacy of the CS/ABZ conjugate. This study suggests that employing such a suitable pair of drug-carriers with dissimilar sites of action, thus allying the different cell cytoskeleton disrupting mechanisms, may provide a more efficient cancer therapy approach.

    Rivalries in the workplace can be destructive to both personal career growth and group success. Many attempts to reverse rivalries fail because of the complex way emotion and reason operate in the building of trust. Using a method called the 3Rs, an effective leader can turn a rival into a collaborator, setting the stage for a healthy work life while driving fresh thinking within an organization. Step 1 of the method is redirection, shifting a rival's negative emotions away from the adversarial relationship. This creates an opening for Step 2, reciprocity, through which a relationship can be established. Here, the essential principle is to give before you ask--offering a rival something of clear benefit and "priming the pump" for a future return that requires little effort on the rival's part. Step 3, rationality, sets expectations of the new relationship so that efforts made using the previous steps don't come off as disingenuous. A rival is encouraged to see collaborative opportunities from a reasoned standpoint. A key advantage of the 3Rs is that the method can work to reverse all kinds of rivalries, including those with subordinates, peers, and superiors.

    The genus Ceratocystis was established in 1890 and accommodates many important fungi. These include serious plant pathogens, significant insect symbionts and agents of timber degradation that result in substantial economic losses. Virtually since its type was described from sweet potatoes, the taxonomy of Ceratocystis has been confused and vigorously debated. In recent years, particulary during the last two decades, it has become very obvious that this genus includes a wide diversity of very different fungi. These have been roughly lumped together due to their similar morphological structures that have clearly evolved through convergent evolution linked to an insect-associated ecology. As has been true for many other groups of fungi, the emergence of DNA-based sequence data and associated phylogenetic inferences, have made it possible to robustly support very distinct boundaries defined by morphological characters and ecological differences. In this study, DNA-sequence data for three carefully selected gene regions (60S, LSU, MCM7) were generated for 79 species residing in the aggregate genus Ceratocystis sensu lato and these data were subjected to rigorous phylogenetic analyses. The results made it possible to distinguish seven major groups for which generic names have been chosen and descriptions either provided or emended. The emended genera included Ceratocystis sensu stricto, Chalaropsis, Endoconidiophora, Thielaviopsis, and Ambrosiella, while two new genera, Davidsoniella and Huntiella, were described. In total, 30 new combinations have been made. This major revision of the generic boundaries in the Ceratocystidaceae will simplify future treatments and work with an important group of fungi including distantly related species illogically aggregated under a single name.

    One of the major barriers to effective team working among healthcare professionals is a lack of knowledge of each other's roles. The importance of understanding Irish healthcare students' attitudes towards team working and each other's roles led to the development of this study. The aims were to investigate allied health professional students' perceptions and experiences of the stroke rehabilitation team and the role of the Speech and Language Therapist (SLT). A survey first developed by Felsher and Ross (1994) and further developed by Insalaco et al. (2007) was adapted to the Irish healthcare setting. The survey was administered to final-year Occupational Therapy (n = 23), Speech and Language Therapy (21) students and Physiotherapy (20) students (64 in total) (a 98.5% response rate). Results indicate that students had a good understanding of teamwork in the healthcare setting and the possible benefits and challenges it presents. Students had a strong appreciation for interprofessional collaboration, with the majority (79%) choosing shared leadership as their preferred option for the stroke rehabilitation team. Further to this, the team approaches that students felt were most appropriate for the stroke rehabilitation setting were the more collaborative approaches of interdisciplinary (43.5%) and transdisciplinary (37.1%). The students had clear perceptions of the SLT's role in aphasia, dysphagia, dysarthria, apraxia and auditory agnosia, but were less knowledgeable of the SLT's role in the acquired disorders of alexia and agraphia (p < 0.05). More than half of all students perceived that the SLT is involved in the treatment of hemispatial neglect (55.5%), depression (71.5%) and visual agnosia (59.4%). The results provide valuable information for further developments in interprofessional education at an undergraduate level. Further opportunities should be provided to students to collaborate with each other, particularly in their final year of training as, by then

    The South African allied health (AH) primary healthcare (PHC) workforce is challenged with the complex rehabilitation needs of escalating patient numbers. The application of evidence-based care using clinical practice guidelines (CPGs) is one way to make efficient and effective use of resources. Although CPGs are common for AH in high-income countries, there is limited understanding of how to do this in low- to middle-income countries. This paper describes barriers and enablers for AH CPG uptake in South African PHC. Semi-structured individual interviews were undertaken with 25 South African AH managers, policymakers, clinicians and academics to explore perspectives on CPGs. Interviews were conducted by researcher dyads, one being familiar with South African AH PHC practice and the other with CPG expertise. Rigour and transparency of data collection was ensured. Interview transcripts were analysed by structuring content into codes, categories and themes. Exemplar quotations were extracted to support themes. CPGs were generally perceived to be relevant to assist AH providers to address the challenges of consistently providing evidence-based care in South African PHC settings. CPGs were considered to be tools for managing clinical, social and economic complexities of AH PHC practice, particularly if CPG recommendations were contextusalised. CPG uptake was one way to deal with increasing pressures to make efficient use of scarce financial resources, and to demonstrate professional legitimacy. Themes comprised organisational infrastructures and capacities for CPG uptake, interactions between AH actors and interaction with broader political structures, the nature of AH evidence in CPGs, and effectively implementing CPGs into practice. CPGs contextualised to local circumstances offer South African PHC AH services with an efficient vehicle for putting evidence into practice. There are challenges to doing this, related to local barriers such as geography, AH training

    Musicians' expressive bodily movements can influence observers' perception of performance. Furthermore, individual differences in observers' music and motor expertise can shape how they perceive and respond to music performance. However, few studies have investigated the bodily movements that different observers of music performance perceive as expressive, in order to understand how they might relate to the music being produced, and the particular instrument type. In this paper, we focus on marimba performance through two case studies—one solo and one collaborative context. This study aims to investigate the existence of a core repertoire of marimba performance expressive bodily movements, identify key music-related features associated with the core repertoire, and explore how observers' perception of expressive bodily movements might vary according to individual differences in their music and motor expertise. Of the six professional musicians who observed and analyzed the marimba performances, three were percussionists and experienced marimba players. Following training, observers implemented the Laban effort-shape movement analysis system to analyze marimba players' bodily movements that they perceived as expressive in audio-visual recordings of performance. Observations that were agreed by all participants as being the same type of action at the same location in the performance recording were examined in each case study, then across the two studies. A small repertoire of bodily movements emerged that the observers perceived as being expressive. Movements were primarily allied to elements of the music structure, technique, and expressive interpretation, however, these elements appeared to be interactive. A type of body sway movement and more localized sound generating actions were perceived as expressive. These movements co-occurred and also appeared separately. Individual participant data revealed slightly more variety in the types and locations of actions

    To evaluate two psychometric properties of the French versions of the Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales, namely their internal consistency and construct validity. The Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales developed by Melnyk et al. are recognised as valid, reliable instruments in English. However, no psychometric validation for their French versions existed. Secondary analysis of a cross sectional survey. Source data came from a cross-sectional descriptive study sample of 382 nurses and other allied healthcare providers. Cronbach's alpha was used to evaluate internal consistency, and principal axis factor analysis and varimax rotation were computed to determine construct validity. The French Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales showed excellent reliability, with Cronbach's alphas close to the scores established by Melnyk et al.'s original versions. Principal axis factor analysis showed medium-to-high factor loading scores without obtaining collinearity. Principal axis factor analysis with varimax rotation of the 16-item Evidence-Based Practice Beliefs scale resulted in a four-factor loading structure. Principal axis factor analysis with varimax rotation of the 17-item Evidence-Based Practice Implementation scale revealed a two-factor loading structure. Further research should attempt to understand why the French Evidence-Based Practice Implementation scale showed a two-factor loading structure but Melnyk et al.'s original has only one. The French versions of the Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales can both be considered valid and reliable instruments for measuring Evidence-Based Practice beliefs and implementation. The results suggest that the French Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales are valid and reliable and can therefore be used to

    Full Text Available Actively seeking health services lies at the core of effective models of chronic disease self-management and contributes to promoting the utilization of allied health services (AHS. However, the use of AHS by ethnic minority Chinese, especially the elderly living in rural areas, has not received much attention. This study, therefore, aims to explore the association between personal characteristics and the activeness of ethnic minority patients with chronic diseases in rural areas of western China seeking AHS. A cross-sectional study was conducted to collect data on the socio-demographic and economic characteristics, health knowledge level and health communication channels of the sampled patients. A logistic regression model was used to examine the association of these predictors with the activeness of the surveyed patients in seeking AHS. A total of 1078 ethnic minorities over 45 years old who had chronic conditions were randomly selected from three western provinces in China and were interviewed in 2014. It is found that the New Cooperative Medical Scheme (NCMS is the most salient predictor affecting the activeness of Chinese ethnic minorities in seeking AHS. The probability is 8.51 times greater for those insured with NCMS to actively seek AHS than those without (95% Confidence Interval (CI 4.76–15.21; p < 0.001. Moreover, participants between 60 and 70 years old and those who have five to six household members are more likely to seek AHS compared with other social groups (Odds Ratio (OR = 1.64, 95% CI 1.28–2.97, p = 0.007; OR = 1.95, 95% CI 1.15–2.36, p = 0.002. However, the activeness of patients seeking AHS is lower for those who have better household economic conditions. Besides socio-demographic predictors, the Chinese ethnic minorities’ activeness in seeking AHS is clearly associated with the communication channels used for receiving health information, which include direct communication with doctors (OR = 5.18, 95% CI 3.58–7

    HIV disproportionately impacts young men who have sex with men (YMSM) who experience disparities across the HIV care continuum. Addressing antiretroviral therapy (ART) adherence among YMSM is an urgent public health priority. Technology-based interventions-particularly mobile health platforms-can provide tailored adherence interventions and allow YMSM to engage and connect with others. The objective of this study was to describe the development of AllyQuest, a novel, theoretically-based, smartphone app designed to improve engagement in care and ART adherence and social support among HIV-positive YMSM. AllyQuest was built on an established platform for patient engagement that embeds social networking and fundamental game mechanics, such as challenges, points, and rewards. A medication tracker provides reminders to promote ART adherence via personalized adherence strategies that are user and context specific; a calendar allows for reflection on adherence over time. After iterative development with input from two youth advisory boards, usability testing was conducted to assess app functionality, comprehension of the educational content, use of intervention features, and overall impressions of app relevance and appeal. A 28-day pilot trial was conducted with 20 HIV+ YMSM to evaluate intervention feasibility and acceptability. Mean age of participants was 21.8 years (range 19-24), and 95% (19/20) of the participants were nonwhite. The mean time of app use was 158.4 min (SD 114.1), with a range of 13 to 441 min. There was a mean of 21.2 days of use (out of a total possible 28 days). There were 222 posts to the daily discussion social wall. Feasibility and acceptability ratings were high. Overall, participants found the app easy to use and navigate, not intrusive, and had few reported technical issues. Higher levels of app usage were positively correlated with HIV self-management outcomes, and there was a statistically significant (P<.05) positive association between the

    Essential learning tools for continuing medical education are a challenge in today's rapidly evolving field of reproductive medicine. The Midwest Reproductive Symposium International (MRSi) is a yearly conference held in Chicago, IL. The conference is targeted toward physicians, geneticists, nurses, allied health professionals, mental health professionals, business administration professionals, and reproductive endocrinology and infertility (REI) fellows engaged in the practice of reproductive medicine. In addition to the scientific conference agenda, there are specific sessions for nurses, mental health professionals, and REI fellows. Unique to the MRSi conference, there is also a separate "Business Minds" session to provide education on business acumen as it is an important element to running a department, division, or private clinic.

    In the United States, young men who have sex with men (YMSM) and transgender women who have sex with men (YTWSM) bear a disproportionate burden of prevalent and incident HIV infections. Once diagnosed, many YMSM and YTWSM struggle to engage in HIV care, adhere to antiretroviral therapy (ART), and achieve viral suppression. Computer-based interventions, including those focused on behavior change, are recognized as effective tools for engaging youth. The purpose of the study described in this protocol is to evaluate the efficacy of Epic Allies, a theory-based mobile phone app that utilizes game mechanics and social networking features to improve engagement in HIV care, ART uptake, ART adherence, and viral suppression among HIV-positive YMSM and YTWSM. The study also qualitatively assesses intervention acceptability, perceived impact, and sustainability. This is a two-group, active-control randomized controlled trial of the Epic Allies app. YMSM and YTWSM aged 16 to 24 inclusive, with detectable HIV viral load are randomized 1:1 within strata of new to care (newly entered HIV medical care ≤12 months of baseline visit) or ART-nonadherent (first entered HIV medical care >12 months before baseline visit) to intervention or control conditions. The intervention condition addresses ART adherence barriers through medication reminders and adherence monitoring, tracking of select adherence-related behaviors (eg, alcohol and marijuana use), an interactive dashboard that displays the participant's adherence-related behaviors and provides tailored feedback, encouragement messages from other users, daily HIV/ART educational articles, and gamification features (eg, mini-games, points, badges) to increase motivation for behavior change and app engagement. The control condition features weekly phone-based notifications to encourage participants to view educational information in the control app. Follow-up assessments are administered at 13, 26, and 39 weeks for each arm.

    North America has a diverse cicada fauna with multiple genera from all three Cicadidae subfamilies, yet molecular phylogenetic analyses have been completed only for the well-studied periodical cicadas (Magicicada Davis). The genus Tibicen Latreille, a large group of charismatic species, is in need of such work because morphological patterns suggest multiple groups with complicated relationships to other genera in the tribe Cryptotympanini. In this paper we present a molecular phylogenetic analysis, based on mitochondrial and nuclear DNA, of 35 of the 38 extant USA species and subspecies of the genus Tibicen together with their North American tribal allies (Cornuplura Davis, Cacama Davis), selected Tibicen species from Eurasia, and representatives of other Eurasian and Pacific cryptotympanine genera. This tree shows that Tibicen contains several well-supported clades, one predominating in eastern and central North America and related to Cryptotympana Stål and Raiateana Boulard, another in western North America related to Cacama and Cornuplura, and at least two clades in Eurasia. We also present a morphological cladistic analysis of Tibicen and its close allies based on 27 characters. Character states identified in the cladistic analysis define three new genera, two for North American taxa (Hadoa gen. n. and Neotibicen gen. n.) including several Mexican species, and one for Asian species (Subsolanus gen. n.). Using relaxed molecular clocks and literature-derived mtDNA rate estimates, we estimate the timeframe of diversification of Tibicen clades and find that intergeneric divergence has occurred since the late Eocene, with most extant species within the former Tibicen originating after the mid-Miocene. We review patterns of ecology, behavior, and geography among Tibicen clades in light of the phylogenetic results and note that the study of these insects is still in its early stages. Some Mexican species formerly placed in Tibicen are here transferred to Diceroprocta

    Full Text Available The present study has been undertaken to investigate the mechanism of thermal stress relief at the range of temperatures below room temperature for the metal matrix composite Al-Li 8090/SiC. For this aim the experimental technique of internal friction has been used which has been showed up very effective. Several thermal cycles from 453 K to 100 K were used in order to measure the internal friction as well as the elastic modulus of the material concluding that thermal stresses are relaxed by microplastic deformation around the reinforcements. It has been also related the variation in the elastic modulus with the different levels of precipitation.

Para ello se ha empleado la técnica experimental de fricción interna que se ha mostrado la más eficaz para tal fin. Aplicando diferentes ciclos térmicos de 453 K a 100 K se midió tanto la fricción interna como el módulo elástico del material concluyendo que el mecanismo de relajación de tensiones térmicas es el de microdeformación plástica alrededor del reforzamiento. También se relaciona la variación del módulo elástico con los diferentes estadios de precipitación.

    Full Text Available Abstract Background Physical activity is recommended for people with peripheral arterial disease (PAD, and can improve walking capacity and quality of life; and reduce pain, requirement for surgery and cardiovascular events. This trial will assess the efficacy of a brief behavioral counselling intervention delivered by allied health professionals to improve physical activity in people with PAD. Methods This is a multi-center randomised controlled trial in four cities across Australia. Participants (N = 200 will be recruited from specialist vascular clinics, general practitioners and research databases and randomised to either the control or intervention group. Both groups will receive usual medical care, a written PAD management information sheet including advice to walk, and four individualised contacts from a protocol-trained allied health professional over 3 months (weeks 1, 2, 6, 12. The control group will receive four 15-min telephone calls with general discussion about PAD symptoms and health and wellbeing. The intervention group will receive behavioral counselling via two 1-h face-to-face sessions and two 15-min telephone calls. The counselling is based on the 5A framework and will promote interval walking for 3 × 40 min/week. Assessments will be conducted at baseline, and 4, 12 and 24 months by staff blinded to participant allocation. Objectively assessed outcomes include physical activity (primary, sedentary behavior, lower limb body function, walking capacity, cardiorespiratory fitness, event-based claudication index, vascular interventions, clinical events, cardiovascular function, circulating markers, and anthropometric measures. Self-reported outcomes include physical activity and sedentary behavior, walking ability, pain severity, and health-related quality of life. Data will be analysed using an intention-to-treat approach. An economic evaluation will assess whether embedding the intervention into routine care would

  18. Covert Operation ``Sun God'' - History of German Solar Research in the Third Reich and Under Allied Occupation (German Title: Kommandosache ``Sonnengott'' - Geschichte der deutschen Sonnenforschung im Dritten Reich und unter alliierter Besatzung)

    Science.gov (United States)

    Seiler, Michael P.

    Between 1939 and 1945 the Luftwaffe of the Third Reich invested large sums in solar research and the establishment of a chain of solar observatories under the code word “Sun God”. Observations of the different phenomena of solar activity were intended to allow a dependable daily prediction of the best frequency bands for long-range military radio. For the development of these research activities the Luftwaffe used a young astrophysicist, who - being the son of a well-known leftist publisher of the Weimar Republic - did appear not well suited to perform “war decisive research” for the Nazi regime: Karl-Otto Kiepenheuer (1910-1975). Circumventing the usual academic tenure, Hitler's war turned the barely thirty-year-old and up to then rather unsuccessful Kiepenheuer into an influential director of a research institution, which he was to remain for the next three decades as well. This book recounts the history of German solar research in the period 1939-1949, her entanglement with the crimes of the Nazi regime as well as her use by the Western Allies until the founding of the German Federal Republic.

    Higher rates of stress-related sickness are found in health care professionals when compared with other sectors. The annual direct cost of absence to the National Health Service is £1.7 billion. Increased clinical demand, long hours, low staffing and a lack of support from colleagues and management are contributing to absenteeism, somatic complaints and mental health problems. Mental health work is inherently stressful and levels of work stress experienced by mental health nurses are especially high. The study investigated mental health nurses' and allied health professionals' (AHPs) awareness and knowledge of the service provided by the Occupational Health Service (OHS) and identified work-related stress and self-care strategies within these two groups. Nurses and AHP staff employed in mental health services in a Scottish healthboard area were invited to complete an anonymous questionnaire. Results demonstrated that staff found their contact with the OHS to be a positive experience. They considered direct patient care to be less stressful than the organizational constraints they work under, and they reported a lack of support from both their peer groups and management. There should be recognition of the increased stress that hospital-based nurses and AHPs experience. These areas should be scrutinized and reviewed further to support staff within these environments in accordance with organizational objectives. © 2010 Blackwell Publishing.

    In 2008, to tackle the exponential rise in the clinical burden of diabetes that was challenging the health systems in Sri Lanka, a shift in focus towards patient-centred care linked with community health promotion was initiated by the National Initiative to Reinforce and Organize General Diabetes Care in Sri Lanka (NIROGI Lanka) project of the Sri Lanka Medical Association. Specific training of "diabetes educator nursing officers" (DENOs), field staff in maternal and child health, footwear technicians, and health promoters from the community, was instituted to improve knowledge, skills and attitudes in the area of control and prevention of diabetes. This article highlights some of the activities carried out to date with the allied health workforce and volunteer community. Specifically, it describes experiences with the DENO programme: the educational and administrative processes adopted, challenges faced and lessons learnt. It also highlights an approach to prevention and management of complications of chronic diabetic foot through training a cohort of prosthetics and orthotics technicians, in the absence of podiatrists, and an initiative to provide low-cost protective footwear. Harnessing the enthusiasm of volunteers - adults and schoolchildren - to address behavioural risk factors in a culturally appropriate fashion has also been a key part of the NIROGI Lanka strategy.

    One of the North Thames' pioneering consortia, the Inner London Consortium (ILC) is a complex body which includes NHS Trusts with teaching hospital university connections, community-based Trusts and general hospital acute Trusts. Within the consortium there are 12,000 trained nurses, midwives, health visitors and other professional staff working in the professions allied to medicine (PAMs), all of whom require access to and provision of appropriate library information services. In 1994, taking into account experiences elsewhere in the Region and nationally, it became clear that library issues were complex and would become acute with the move of nursing libraries from ILC Trust sites over a very short timescale. A report on the issues commissioned by the Consortium recommended that a library project, which built on existing NHS Trust PGMDE funded library resources and moved these to a multidisciplinary base to serve the consortium membership, be implemented. The objective of providing access to library information services for nurses and PAMs was achieved. Successes that emerged from the implementation included: The registration in Trust libraries of almost 12 000 new members within the initial 6-month monitoring period. The development of service level agreements and standards for the delivery of services to these new user groups. This paper describes the processes behind these significant and complex changes.

    Awareness of food safety is rising among consumers, and many importing countries implement food control regulations to guarantee the quality and safety of imported foods for their consumers. Many developing countries have also taken steps to put in place control systems that encourage responsible use of veterinary medicines to combat possible drug resistance, control drug residues and ensure compliance with international and national standards. However, these countries still require the necessary know-how and skills to protect local consumers and to access international markets. One significant constraint is the capacity of laboratory services to generate surveillance data using reliable and cost effective analytical methods validated to national and international standards. The IAEA coordinated research project (CRP) on the Development of Radiometric and Allied Analytical Methods to Strengthen National Residue Control Programmes for Antibiotic and Anthelmintic Veterinary Drug Residues was initiated in 2009 to conduct work on robust nuclear and related technologies suitable for the screening and confirmatory analysis of residues of veterinary medicines, including antimicrobials and anthelmintics commonly used in animal production, with public health and trade significance. The CRP also explored mechanisms to enhance networking among research institutions involved in research on pharmacologically active veterinary drug residues in food (primarily) and environmental samples. The project was implemented by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture between 2009 and 2014 and involved eleven research contracts and one technical contract, five research agreements and one institution. The CRP was a continuation of the CRP on the Development of Strategies for the Effective Monitoring of Veterinary Drug Residues in Livestock and Livestock Products in Developing Countries and the key findings are also summarized in this publication.

    Between February and September of 2003, Environment Canada held a series of consultation sessions on a set of proposed regulations in order to eliminate the contamination of groundwater and soil caused by petroleum products and allied petroleum products stored by the federal house in storage tank systems. This document presents a summary of comments, issues, ideas and perspectives raised throughout consultation sessions. It also outlines Environment Canada's responses to generated input. Sessions took place in each of Environment Canada's five regions. A full description of the consultation procedures and methodology was provided. The document provides a rationale for cases where Environment Canada has rejected or only partially accepted stakeholder recommendations. A list of general prohibitions and obligations was provided along with details of registration and tagging; provincially-approved installers and installation procedures; monitoring and leak detection; operation and maintenance; upgrading; withdrawal, re-use and removal of storage tank systems; report of releases; and an environmental emergency plan and record keeping. First Nation issues were also discussed. Several changes to proposed regulations have been made during the course of the consultations, including an extension of timelines for compliance with proposed regulations; the definition of a storage tank system is now defined as the delivery point first connection to the discharge of the pump; and records are now required for only 7 years as opposed to the life of the tank. It was also stated that a draft regulation will be published in the Canadian Gazette, followed by a 60 day comment period. The final regulation will be published a few months later

    The European Society of Cardiology and the Council on Cardiovascular Nursing and Allied Professions share a vision; to decrease the burden of cardiovascular disease in Europe. Nurses represent the largest sector of the health professional workforce and have a significant contribution to make, which has not yet been fully realised. Recent evidence highlights an association between the level of nurse education and inpatient mortality making this an important topic, particularly as the provision of nurse education in Europe is variable. To develop a core curriculum to inform the education of nurses following initial qualification for work in cardiovascular settings. A syllabus was developed using published literature, policy documents and existing curricula with expert input from service users, specialist nurses, cardiologists, educationalists and academics. The syllabus formed the framework for the development of the core curriculum. Eight key themes characterise the core curriculum which are presented together with an account of the development process. While the curriculum is not intended to cover all aspects of the highly complex role of the cardiovascular nurse, the themes do exemplify the science and art of nursing and are transferable across different levels of clinical practice and settings. The curriculum functions both as a 'map', which identifies key themes to include in nurse education, and as a 'tool' to inform educational provision that bridges' the gap between initial nurse education and advanced specialist practice. Content can be adapted for use to fit the national context and reflects the specific needs, health priorities, legislative and regulatory standards that govern safe nursing practice across different countries. The core curriculum can be used as a learning framework to guide nurse education, in particular the continuing professional education of post-qualifying nurses working in cardiovascular settings. This represents a significant step

  7. Thermal fatigue cracking of austenitic stainless steels; Fissuration en fatigue thermique des aciers inoxydables austenitiques

    Fissolo, A

    2001-07-01

    This report deals with the thermal fatigue cracking of austenitic stainless steels as AISI 316 LN and 304 L. Such damage has been clearly observed for some components used in Fast Breeder reactors (FBR) and Pressure Water Reactor (PWR). In order to investigate thermal fatigue, quasi-structural specimen have been used. In this frame, facilities enforcing temperature variations similar to those found under the operation conditions have been progressively developed. As for components, loading results from impeded dilatation. In the SPLASH facility, the purpose was to establish accurate crack initiation conditions in order to check the relevance of the usual component design methodology. The tested specimen is continuously heated by the passage of an electrical DC current, and submitted to cyclic thermal down shock (up to 1000 deg C/s) by means of periodical spraying of water on two opposite specimen faces. The number of cycles to crack initiation N{sub i} is deduced from periodic examinations of the quenched surfaces, by means of optical microscopy. It is considered that initiation occurs when at least one 50{mu}m to 150{open_square}m long crack is observed. Additional SPLASH tests were performed for N >> N{sub i}, with a view to investigate the evolution of a surface multiple cracking network with the number of cycles N. The CYTHIA test was mainly developed for the purpose of assessing crack growth dynamics of one isolated crack in thermal fatigue conditions. Specimens consist of thick walled tubes with a 1 mm circular groove is spark-machined at the specimen centre. During the test, the external wall of the tube is periodically heated by using a HF induction coil (1 MHz), while its internal wall is permanently cooled by flowing water. Total crack growth is derived from post-mortem examinations, whereby the thermal fatigue final rupture surface is oxidized at the end of the test. The specimen is broken afterwards under mechanical fatigue at room temperature. All the tests confirm that usual approaches are adapted in used conditions ( 280 {<=} T{sub max} {<=} 550 deg C, 100 {<=} {open_square}T {<=} 300 deg C): they are simply based on thermal loading mechanical loading equivalence. However, they appear not to be well adapted when additional factors exist such as roughness, residual stresses... Furthermore, Scanning Electron Microscopy observations show that damage is initiated well before the 'engineer initiation', as previously detected using optical microscopy on SPLASH specimen. First stage damage evolutions are thus a new task. Strain and stress fields generated during test are estimated thanks to finite element method computations (FEM), using CASTEM-2000 CEA software. Information coming from these FEM computations monitor lower-scale modelling: Discrete dislocation Dynamics (MICROMEGAS software). In order to continue that task, a new specimen has been adapted to the CYTHIA facility. Specimens consist of removable disks in which different and well-controlled conditions may be enforced. In order to estimate propagation of long crack, conventional fracture mechanic approach seems to be well adapted. The effective Stress Intensity Factor calculation takes into account of plastic strain. Furthermore, it is assumed that crack is opened during 60 % of cyclic loading. Shielding effect is clearly underlined by all the observations: on surface, on cross side section, and after sub-surface step-by-step removal. Multiple crack propagation (in the depth direction) is simulated using the previous single crack modelling. An auto-adaptative meshing allows simulating growth of 10 cracks up to 35,000 cycles. Two-development tasks are now in progress. The first task is oriented on the multiple crack growth and stability after an additional mechanical loading. The second task deals with the first damage stage up to the 'engineer crack initiation'. (author)

    Intergranular cracking can occur in heat-affected zones (HAZs) of austenitic stainless steel welded joints when reheated in the temperature range from 500 to 700 deg C. At this temperature, residual stresses due to welding relax by creep flow. HAZ may not sustain this small strain if its microstructure has been sufficiently altered during welding. In order to precise which particular microstructure alteration causes such an intergranular embrittlement, type 316L(N) HAZs were examined by transmission electron microscopy. A marked increase in the dislocation density, due to plastic strain during the welding process, was revealed, which caused an increase in Vickers hardness. Type 316L(N) HAZ were then simulated by the following thermal-mechanical process: annealing treatment and work hardening (pre-strain). Creep rupture tests on smooth specimens were also carried out at 600 deg C on both base metal and simulated HAZ. Pre-straining increased creep strength but reduced ductility. Slow strain rate tests on CT specimens confirmed this trend as well as did relaxation tests on CT specimens, which led to intergranular crack propagation in the pre-strained material only. Metallography and fractography showed no qualitative difference between base metal and HAZs in the creep cavitation around intergranular carbides. Although quantitative study of damage development is not achieved yet, experiments suggest that uniaxial creep strain smaller than one percent could lead to cavity nucleation when the material is pre-strained. Pre-strain as well as stress triaxiality reduce therefore creep ductility and enhance the reheat cracking risk. (authors)

    Maria Alessandra Gammone

    2015-02-01

    Full Text Available Carotenoids are a class of natural, fat-soluble pigments found principally in plants. They have potential antioxidant biological properties because of their chemical structure and interaction with biological membranes. Epidemiologic studies supported the hypothesis that antioxidants could be used as an inexpensive means of both primary and secondary cardiovascular disease (CVD prevention. In fact, the oxidation of low-density lipoproteins (LDL in the vessels plays a key role in the development of atherosclerotic lesions. The resistance of LDL to oxidation is increased by high dietary antioxidant intake, so that carotenoids, as part of food patterns such as the Mediterranean diet, may have beneficial effects on cardiovascular health too. Further properties of carotenoids leading to a potential reduction of cardiovascular risk are represented by lowering of blood pressure, reduction of pro-inflammatory cytokines and markers of inflammation (such as C-reactive protein, and improvement of insulin sensitivity in muscle, liver, and adipose tissues. In addition, recent nutrigenomics studies have focused on the exceptional ability of carotenoids in modulating the expression of specific genes involved in cell metabolism. The aim of this review is to focus attention to this effect of some carotenoids to prevent CVD.

In ecosystems, bats are actors with leading roles, 70% of them are insectivores, pollinators, or frugivorous and contribute to the regeneration of forests by disseminating seeds. Some are even fish hunters. Although their large population is mostly distributed in the tropics, they are cosmopolitan and are also found in the Northern Hemisphere. The population of these bats has been displaced in the South American tropics, due to, among many factors, illegal mining, pesticide spraying, indiscriminate deforestation to provide pasture for cattle, and the invasion of their habitats by humans (1.

    Under the 1990 Clean Air Act Amendments (CAAA), scrubbing and emission allowance trading will play complementary roles. This paper reviews Phase I announced strategies and presents projections of technology controls, coal switching and industry-wide SO 2 removal costs under different assumptions about trading. The principal uncertainties characterizing today's planning environment are discussed -- ranging from changing expectations for fuel costs to swings in allowance prices and questions about regulation and new operating procedures. Economic forecasting is difficult. A clearer picture of Phase 2 strategies is emerging from EPRI's integrated analysis of fuel, technology and allowance markets -- based on collaboration between A. Van Horn and K. White (management consultants) and T. Hewson (Energy Ventures Analysis). About half the SO 2 reductions required in Phase 2 are likely to come from technology controls and half from coal switching. With trading, the highest cost open-quotes scrubsclose quotes and open-quotes switchesclose quotes can be avoided, more upgrading of low-cost scrubbing is expected, and the role of switching grows to a small extent. Additional benefits from trading, averaging and banking allowances are: better sequencing of technology controls, less stringent specs for equipment, and added flexibility/risk-sharing opportunities in contract arrangements

  20. When to ally & when to acquire.

    2004-01-01

    Acquisitions and alliances are two pillars of growth strategy. But most businesses don't treat the two as alternative mechanisms for attaining goals. Consequently, companies take over firms they should have collaborated with, and vice versa, and make a mess of both acquisitions and alliances. It's easy to see why companies don't weigh the relative merits and demerits of acquisitions and alliances before choosing horses for courses. The two strategies differ in many ways: Acquisition deals are competitive, based on market prices, and risky; alliances are cooperative, negotiated, and not so risky. Companies habitually deploy acquisitions to increase scale or cut costs and use partnerships to enter new markets, customer segments, and regions. Moreover, a company's initial experiences often turn into blinders. If the firm pulls off an alliance or two, it tends to enter into alliances even when circumstances demand acquisitions. Organizational barriers also stand in the way. In many companies, an M&A group, which reports to the finance head, handles acquisitions, while a separate business development unit looks after alliances. The two teams work out of different locations, jealously guard turf, and, in effect, prevent companies from comparing the advantages and disadvantages of the strategies. But companies could improve their results, the authors argue, if they compared the two strategies to determine which is best suited to the situation at hand. Firms such as Cisco that use acquisitions and alliances appropriately grow faster than rivals do. The authors provide a framework to help organizations systematically decide between acquisition and alliance by analyzing three sets of factors: the resources and synergies they desire, the marketplace they compete in, and their competencies at collaborating.

    ZnO has been the central theme of research in the past decade due to its various applications in band gap engineering, and textile and biomedical industries. In nanostructured form, it offers ample opportunities to realize tunable optical and optoelectronic properties and it was also termed as a potential material to realize room temperature ferromagnetism. This book presents 17 high-quality contributory chapters on ZnO related systems written by experts in this field. These chapters will help researchers to understand and explore the varied physical properties to envisage device applications of ZnO in thin film, heterostructure and nanostructure forms.

  4. Art: ally or tool in science teaching?

    Directory of Open Access Journals (Sweden)

    Fernando Cesar Ferreira

    2012-10-01

    Full Text Available We know that art and science have influenced one another over the centuries. As an example, in the nineteenth century, the poets of the Romantic movement portrayed in some of their most beautiful poems the anguish they felt facing the development of thermodynamics and the possibility of heat death of the universe. In recent years different methodological possibilities have been put in evidence in science education: experimenting with low cost materials, history of science, virtual environments, among others. We believe that the art in this process has played an important role, but still marginal, because, as well as science, it also produces knowledge about reality. However, their potential is perceived more as a tool for teaching rather than as an active participant in building relationships and about the nature of humankind.

    An examination has been carried out of non-alloyed uranium samples, having various structural states, cold-worked and recrystallized, as-cast and {beta}-treated, and irradiated at temperatures of between 450 and 600 C and with burn-ups from 1300 to 5500 MW days/metric ton. These samples swelled because of precipitation of the fission gases the porosity thus produced has a morphology depending mainly on the type of deformation to which the metal has been subjected and which is due to in-pile growth. The most homogeneous distribution of pores, and thus that leading to the minimum swelling, is only observed in the material having a marked [010] texture in which the growth and perhaps the thermal cycling introduce little or no strain. For other materials the deformation /swelling association causes a more rapid destruction of the samples either by cracking when the deformation is due to twinning, or by pronounced swelling localized in the bands when deformation is due to slipping. Finally the fission-gas precipitation considerably facilitates, above 500 C, the germination and growth of the intergranular cracks which can then develop at low stresses. (author) [French] On a examine des echantillons d'uranium non allie, de divers etats structuraux, marteles et recristallises, bruts de coulee et traites {beta}, irradies a des temperatures comprises entre 450 et 600 C, et a des taux de combustion allant de 1300 a 5500 MWj/t. Ces echantillons ont gonfle par suite de la precipitation de gaz de fission: la porosite ainsi fournie a une morphologie qui depend principalement des modes de deformation subie par le metal et due a la croissance en pile. La repartition la plus homogene des pores, donc celle qui donnera le gonflement minimum, est observee seulement dans le materiau a forte texture [010] dans lequel la croissance et eventuellement le cyclage thermique introduisent peu ou pas de contraintes. Dans les autres materiaux l'association deformation/gonflement rend plus rapide

    La température de contact lors des essais d'usure varie d'une manière spontanée et aléatoire. Cette température de contact dépend essentiellement de la nature du couple des matériaux en contact de la charge et de la vitesse. Cependant la mesure de la température est très difficile à effectuer compte tenu du choix de l'endroit de prise de la température et des phénomènes d'évacuation de la chaleur et de la dissipation de l'énergie. Dans ce travail nous exposons une méthode très simple de mesure de la température et nous étudions par conséquent la variation de la température du Z12CNS20 / Z200C13. Au cours des essais d'usure pour différentes vitesses de glissement, nous montrons en effet que la température augmente d'une manière progressive en fonction de la vitesse puis elle s'élève brutalement au fur et à mesure qu'on se rapproche du point de contact, et enfin nous prouvons par observation métallographique que l'échantillon subit un écoulement plastique provoqué par l'élévation de la température en fonction de la vitesse.

  8. Welding hot cracking in an austenitic stainless steel; Fissuration a chaud en soudage d'un acier inoxydable austenitique

    Energy Technology Data Exchange (ETDEWEB)

    Kerrouault, N

    2001-07-01

    The occurrence of hot cracking is linked to several conditions, in particular, the composition of the material and the local strains due to clambering. The aim of this study is to better analyse the implied mechanisms and to lead to a local thermomechanical criterion for hot cracking. The example studied is an AISI 321-type stainless steel (X10CrNiTi18-12) strongly prone to cracking. Two weldability tests are studied: - the first one consists in carrying out a fusion line by the TIG process on a thin sheet. In the case of the defect occurrence, the crack is longitudinal and follows the back of the molten bath. The influence of the operating conditions welding (speed, welding heat input, width test sample) is studied. - the second one is the Varestraint test. It is widely used to evaluate the sensitivity of a material to hot cracking. It consists in loading the material by bending during a fusion line by the TIG process and in characterising the defects quantity (length, number). Various thermal and mechanical instrumentation methods were used. The possibilities of a local instrumentation instrumentation being limited because of the melting, the experimental results were complemented by a numerical modelling whose aim is to simulate the thermomechanical evolution of the loading thanks to the finite element analysis code ABAQUS. First, the heat input for thermal simulation is set by the use of an inverse method in order to optimise the energy deposit mode during welding in the calculation. Then, the mechanical simulation needs the input of a constitutive law that fits the mechanical behaviour over a wide temperature range from ambient to melting temperature. Thus, a mechanical characterization is performed by selecting strain values and strain rates representative of what the material undergoes during the tests. The results come from tensile and compressive tests and allow to settle an elasto-visco-plastic constitutive law over temperatures up to liquidus. Once validated, the thermomechanical simulation brings new interpretations of the tests observations and instrumentation results. The comparison of experimental and numerical results make it possible to determine a thermomechanical welding hot cracking criterion during solidification. This criterion simultaneously considers mechanical (strain and strain rates threshold) and thermal (temperature range, thermal gradient) parameters which give the position and orientation of the first crack initiation. The criterion precision are in good agreement with the observations on the two considered weldability tests. (author)

    2013-11-01

    Full Text Available The relationship between microstructure and mechanical properties of MaX (1.4006 martensitic stainless steel has been studied. Optical microscopy was used to characterize the microstructure and the volume fraction of retained ferrite was measured by image analysis. Mechanical properties were measured in uni-axial tensile testing and a composite model has been developed to capture the effect of both the retained ferrite and the carbon content of the martensitic phase. First results show a reasonable correlation between the experimental stress-strain curves and the model. Results are discussed in view of a previous study on plain martensitic carbon steels.

    2001-01-01

    The aim of this work is to optimize the performance of structural materials. The elementary mechanisms (strain hardening and dynamical regeneration, germination and growth of new grains) occurring during the hot working of metals and low pile defect energy alloys have been studied for austenitic stainless steels. In particular, the influence of the main experimental parameters (temperature, deformation velocity, initial grain size, impurities amount, deformation way) on the process of discontinuous dynamical recrystallization has been studied. Alloys with composition equal to those of the industrial stainless steel-304L have been fabricated from ultra-pure iron, chromium and nickel. Tests carried out in hot compression and torsion in order to cover a wide range of deformations, deformation velocities and temperatures for two very different deformation ways have allowed to determine the rheological characteristics (sensitivity to the deformation velocity, apparent activation energy) of materials as well as to characterize their microstructural deformations by optical metallography and electron back-scattered diffraction. The influence of the initial grain size and the influence of the purity of the material on the dynamical recrystallization kinetics have been determined. An analytical model for the determination of the apparent mobility of grain boundaries, a semi-analytical model for the dynamical recrystallization and at last an analytical model for the stationary state of dynamical recrystallization are proposed as well as a new criteria for the transition between the refinement state and the state of grain growth.

    After defining field emission in metallic tips, we examine thoroughly a theory of photo-field emission following the works of Bagchi, Schwartz and Gao. This theory is compared to the experimental results of Reifenberger et al. We study the field emission in a semiconductor, following R. Stratton, and we propose a new theoretical interpretation of the anomalous growth of current with field, as it often occurs in the characteristic current-voltage. We assume the creation by the field of a dynamic quantum well in the surface conduction band. As a consequence of the induced degeneracy, we express theoretically the contribution to the current, of the electrons confined in the well. We compare this hypothesis to the emission of doped P silicon. There is a fairly good agreement. Assuming that the electrons are confined in the well, we develop a new theoretical approach of the photo-field emission of a degenerated semiconductor. We derive the photoelectric transition probability in the case of laser YAG pulse of picosecond duration, then the photocurrent densities of various photonic energies for distinct values of electric field, taking into account the optical property of the medium. We are thus able to interpret our experimental results with a good agreement. This original development should enable us to predict the behaviour of our tipped photocathodes in photo-injectors (CLIC, CANDELA, Tesla). These photocathodes could be interesting in infrared detection. (author) 55 refs.

    From the results already obtained in France by monitoring radioactivity in the neighbourhood of nuclear plant, some conclusions may be drawn regarding the choice of disposal procedures. I. Results obtained In 1957 we started a progressive study of the effect exerted by nuclear plant. In order to establish the proportion due to the nuclear centres, the study comprises determination of the levels of natural radioactivity and artificial contamination. Examples related to reference areas are quoted. The greater part of artificial radioactivity is apparently due to radioactive fall-out; this is not surprising, considering the quantities of radioactive isotopes disposed of in France to date. Some laboratory tests have been made. These have helped to determine certain mechanisms, have increased our knowledge of site pollution, and have enabled us to improve our sampling methods. II. Laboratory tests These were concerned with 1. adsorption phenomena similar to those occurring in rivers and streams in the course of effluent dilution: fixation on finely-divided minerals, e.g. mica and quartz. Radioisotopes such as Sr{sup 9}'0, Cs{sup 137} and Y{sup 90} appear to behave very differently: under average disposal conditions Sr{sup 90} seems to be the least adsorbed; 2. soil and plant contamination, utilizing columns and cubes of soil in situ. We found it necessary to standardize our samples so as to facilitate further analysis and make the results comparable. III. Site selection and ways and means of disposal From this group of still incomplete results and studies we are attempting to educe certain principles to govern site selection. Once the site has been chosen, the experience gained enables natural conditions to be turned to account. (author) [French] Des resultats deja fournis par la surveillance en France, de la radioactivite aux alentours des installations nucleaires, il est possible de tirer certains enseignements quant au choix des processus de rejet. I. Resultats obtenus Nous avons commence en 1957 une etude evolutive de l'incidence des installations nucleaires. Cette etude embrasse la determination des niveaux - de radioactivite naturelle - de contamination artificielle afin d'en degager la part revenant aux Centres Nucleaires. Des exemples sont cites faisant appel a des zones de reference. La plus grande partie de la radioactivite artificielle semble due aux retombees radioactives; ceci n'est pas surprenant si on examine les quantites d'isotopes radioactifs rejetees jusqu'a present en France. Un certain nombre d'essais de laboratoire ont ete effectues. Ils ont contribue a preciser certains mecanismes, ont accru notre connaissance de la pollution des sites et nous ont permis d'ameliorer nos methodes de prelevement. II. Essais de laboratoire Ils ont porte: 1. sur des 'phenomenes d'adsorption analogues a ceux produits dans les rivieres au cours de la dilution des effluents: fixation sur mineraux tres divises: mica, quartz. Des radioisotopes tels que {sup 90}Sr, {sup 137}Cs, {sup 90}Y semblent se comporter fort differemment: dans les conditions moyennes de rejet, le {sup 90}Sr serait le moins adsorbe. : 2. sur la contamination du sol et des vegetaux par l'emploi de colonnes et de cubes de sol en place. Ceci nous a conduit a standardiser nos prelevements, afin de faciliter les analyses ulterieures et de comparer utilement les resultats. III. Choix du site et modalites des rejets De ce faisceau de resultats et d'etudes encore incomplets, nous essayons de degager quelques principes quant au choix des sites. Le site une fois defini, l'experience acquise permet de tirer le meilleur parti des possibilites naturelles.

El estudio comprende la determinacion de los niveles - de radiactividad natural - de contaminacion artificial con objeto de determinar la parte que corresponde a los centros nucleares.

    Biological nitrogen fixation (BNF) by crop legumes reduces demand for industrial nitrogen fixation (INF). Nonetheless, rates of BNF in agriculture remain low, with strong negative feedback to BNF from reactive soil nitrogen (N) and drought. We show that breeding for yield has resulted in strong relationships between photosynthesis and leaf N in non-leguminous crops, whereas grain legumes show strong relations between leaf N and water use efficiency (WUE). We contrast these understandings with other studies that draw attention to the water costs of grain legume crops, and their potential for polluting the biosphere with N. We propose that breeding grain legumes for reduced stomatal conductance can increase WUE without compromising production or BNF. Legume crops remain a better bet than relying on INF.

    The color design processes of visual artists, architects, designers, and theoreticians included in this presentation reflect the practical role of color in architecture. What the color design professional brings to the architectural design team is an expertise and rich sensibility made up of a broad awareness and a finely tuned visual perception. This includes a knowledge of design and its history, expertise with industrial color materials and their methods of application, an awareness of design context and cultural identity, a background in physiology and psychology as it relates to human welfare, and an ability to problem-solve and respond creatively to design concepts with innovative ideas. The broadening of the definition of the colorists's role in architectural design provides architects, artists and designers with significant opportunities for continued professional and educational development.

  12. Induced variability in quantitative characters in some allied fibre crops

    International Nuclear Information System (INIS)

    Singh, D.P.

    1975-01-01

    Variability in plant height, basal diameter and the number of internodes was induced in some varieties of Kenaf (H.C. and H.S.), Malachra and Ramie (boehmaria nivea) using chronic gamma ryays of different intensities. The statistical analysis showed significant treatment difference. A detailed study made with the help of five statistics i.e. mean, variance, S.D.S.E and C.V.% in M3 generation, revealed that the treatments show variable effects on these characters, and the highest variability is induced under the higher dose. Among all the types, however, Hibiscus cannabinus was found to be more radiosensitive. In Ramie, the differences due to treatments were significant, but not much difference was observed in the behaviour of different variaties towards gamma rays. Results have been discussed using the findings obtained earlier in jute. (author)

    We explore the effectiveness of tin (Sn), by alloying it with silicon, to use SiSn as a channel material to extend the performance of silicon based complementary metal oxide semiconductors. Our density functional theory based simulation shows that incorporation of tin reduces the band gap of Si(Sn). We fabricated our device with SiSn channel material using a low cost and scalable thermal diffusion process of tin into silicon. Our high-κ/metal gate based multi-gate-field-effect-transistors using SiSn as channel material show performance enhancement, which is in accordance with the theoretical analysis. © 2014 WILEY-VCH Verlag GmbH & Co.

  19. Soluble elastin peptides in cardiovascular homeostasis: Foe or ally.

    Science.gov (United States)

    Qin, Zhenyu

    2015-05-01

    Elastin peptides, also known as elastin-derived peptides or elastokines, are soluble polypeptides in blood and tissue. The blood levels of elastin peptides are usually low but can increase during cardiovascular diseases, such as atherosclerosis, aortic aneurysm and diabetes with vascular complications. Generally, elastin peptides are derived from the degradation of insoluble elastic polymers. The biological activities of elastin peptides are bidirectional, e.g., a pro-inflammatory effect on monocyte migration induction vs. a protective effect on vasodilation promotion. However, recent in vivo studies have demonstrated that elastin peptides promote the formation of atherosclerotic plaques in hypercholesterolemic mice and induce hyperglycemia and elevations in plasma lipid levels in fasted mice. More important, the detrimental effects induced by elastin peptides can be largely inhibited by genetic or pharmacological blockade of the elastin receptor complex or by neutralization of an antibody against elastin peptides. These studies indicate new therapeutic strategies for the treatment of cardiovascular diseases by targeting elastin peptide metabolism. Therefore, the goal of this review is to summarize current knowledge about elastin peptides relevant to cardiovascular pathologies to further delineate their potential application in cardiovascular disease.

    2005-01-01

    In Pakistan, about two-thirds of the primary energy requirements are met through conventional sources while traditional biomass accounts the remaining one-third The primary commercial energy is largely based on fossil fuels. Indigenous reserves of oil and gas are limited and the coal available in the country is of poor quality. Environmental pollution and greenhouse gas emissions from energy use are becoming significant environmental issues in the country. Achieving solutions to these environmental problems requires long-term potential actions for sustainable development. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions. Pakistan's geographical location has several advantages for extensive use of most of these renewable energy sources. This paper presents review of the present energy situation and environmental sustainability, and assesses the potential of renewable energy sources in Pakistan. Also, potential solutions to current environmental problems are identified along with renewable energy technologies. Several problems relating to renewable energy sources, environmentally sustainable development are discussed from both current and future perspectives. The present study shows that there is substantial potential of renewables in Pakistan. For achieving environmentally sustainable development, renewables must be developed and utilized. (author)

    Electrical equipment that was damaged by the beech marten has been repaired. The LHC is back on track with ever higher beam intensity.    Technicians at work on the transformer that was damaged by the beech marten. (Image: Stefano Bertolasi/CERN) Early in the morning of Friday, 29 April, the LHC was running with Stable Beams with 49 bunches per beam. Earlier that week, the scrubbing run had been cut short after a vacuum leak had developed in the SPS beam dump. Following this, the LHC had started its planned intensity ramp-up, albeit with a limited number of bunches per injection from the SPS to avoid overstressing the compromised beam dump. At 05:32:16 on Friday, the beams were dumped. The logbook entry reads “Foreign object (weasel) found on the 66kV transformer in P8, causing severe electrical disturbance throughout the complex”. The weasel, later more accurately identified as a beech marten, had taken out a 66 to 18 kV transformer at Point 8 of th...

    Full Text Available Service-learning and social entrepreneurship share a common goal of engaging students in work to achieve the public good, and a desire to link education to addressing social problems and needs. Yet an examination of the two initiatives reveals that they generally co-exist on college and university campuses with little or no collaboration or communication between the two programs. This paper examines the definitions and core identities of service-learning and social entrepreneurship, exploring the potential for how the two initiatives might complement and support one another’s work in higher education. This examination includes identifying the values, philosophies, and practices that might provide common ground as well as those that might present points of conflict and tension. KEYWORDSService-learning; Social Entrepreneurship; Civic Engagement

  15. Between Allies and Rivals: Turkey, Nuclear Weapons, and BMD

    International Nuclear Information System (INIS)

    Kibaroglu, Mustafa

    2014-01-01

    This paper discusses Turkey's attitudes vis-a-vis nuclear weapons and Ballistic Missile Defense in the light of recent developments in the Iranian nuclear program and NATO's evolving concept of extended deterrence. On the one hand, the long-standing forward deployment of US tactical nuclear weapons in Turkey and the country's role in the US Phased Adaptive Approach BMD architecture are still considered to be key elements of national security. On the other, security guarantees offered to Turkey by NATO and the US appear less and less credible in the face of rising regional threats. As this paper shows, there is a growing gap between official policy and public perceptions inside Turkey vis-a-vis the US, Iran, and nuclear weapons, as well as a growing Turkish aspiration to autonomy in its security and defense policy. While one should not expect Turkey to develop nuclear weapons anytime soon, an unchecked Iranian regional power could bring Ankara to hedge its bets in the long term. Turkey's controversial recent decision to buy a Chinese system for its national air and missile defense rather than European or US equipment should be seen in the light of this search for autonomy.

  18. Naturalism and the social model of disability: allied or antithetical?

    Science.gov (United States)

    Sisti, Dominic A

    2015-07-01

    The question of how disability should be defined is fraught with political, ethical and philosophical complexities. The social model of disability, which posits that disability is socially and politically constructed and is characterised by systemic barriers, has enjoyed broad acceptance that is exemplified by the slow but steady progress in securing civil rights for persons with disabilities. Yet, there remains a palpable tension between disability studies scholars and activists and bioethicists. While philosophers and bioethicists should heed the theories developed from the standpoint of persons with disabilities, disability activists should acknowledge the possibility that philosophical theories about the basic reality of disease, illness, health, function and impairment offer a more steady foundation for social or political critiques of disability. I argue that naturalistic theories of function and dysfunction provide a valuable starting point to clarify questions about the broader concept of disability. A naturalist theory of function may serve as the core of the concept of disability and provide disability scholars and bioethicists alike a stronger set of arguments in analysing real or potential instances of disability.

  19. The role of hydropower in environment ally sustainable energy development

    International Nuclear Information System (INIS)

    Gabriel, H.F.

    2005-01-01

    Hydropower has historically been the renewable energy leader, and from a technical-cost perspective, is very likely to remain the only viable renewable energy source for many countries. In recent years, hydropower has been much maligned, especially by NGOs, for not being a sustainable source of energy. Though hydropower is clearly a renewable source of energy, but the question arises whether it can also be sustainable. Hydropower can play an increasingly important role in enabling communities around the world to meet sustainability objectives. To become more accepted as a key contributor to sustainable energy systems, new and existing hydropower projects need to be built and operated in an environmentally, socially and economically sustainable manner. This paper highlights the sustain ability aspects of hydropower and discusses the criteria for selection of environmentally friendly hydropower project sites so that that hydropower can be developed in a sustainable manner and once again be considered favorably in the planning of generation mix for new energy development. Sustainability of hydropower projects involves treating both the social and environmental sustainability of the project at an early stage and including the interests of all stakeholders of the project. As a case study, the Ghazi- Barotha Hydropower Project (GBHP) in Pakistan has been selected, as it is the best example in managing the social issues and gaining public acceptance because of proper planning and addressing environmental and social issues at an early stage.

  20. Trusted Allies with New Benefits: Repositioning Existing Drugs

    KAUST Repository

    Gao, Xin

    2016-01-25

    The classical assumption that one drug cures a single disease by binding to a single drug-target has been shown to be inaccurate. Recent studies estimate that each drug on average binds to at least six known and several unknown targets. Identifying the “off-targets” can help understand the side effects and toxicity of the drug. Moreover, off-targets for a given drug may inspire “drug repositioning”, where a drug already approved for one condition is redirected to treat another condition, thereby overcoming delays and costs associated with clinical trials and drug approval. In this talk, I will introduce our work along this direction. We have developed a structural alignment method that can precisely identify structural similarities between arbitrary types of interaction interfaces, such as the drug-target interaction. We have further developed a novel computational framework, iDTP that constructs the structural signatures of approved and experimental drugs, based on which we predict new targets for these drugs. Our method combines information from several sources including sequence independent structural alignment, sequence similarity, drug-target tissue expression data, and text mining. In a cross-validation study, we used iDTP to predict the known targets of 11 drugs, with 63% sensitivity and 81% specificity. We then predicted novel targets for these drugs—two that are of high pharmacological interest, the peroxisome proliferator-activated receptor gamma and the oncogene B-cell lymphoma 2, were successfully validated through in vitro binding experiments.

  1. Fluvial Geomorphology and River Restoration: Uneasy Allies (Invited)

    Science.gov (United States)

    Kondolf, G. M.

    2009-12-01

    A growing body of literature demonstrates that river restoration based on understanding of geomorphic and ecological process is more likely to be sustainable than form-based approaches. In the early days of river ‘restoration’ in North America, most projects involved bank stabilization, habitat structure placement, or construction of rocked meandering channels, at odds with restoration of the dynamic processes we now see as fundamental to effective, sustainable restoration. Recent years have seen a growing body of restoration programs emphasizing restoration of connectivity and geomorphic process. This evolution has been reflected in publications, from the form-based approach advocated in the early 1990s by an NRC panel (which did not include a geomorphologist) to more recent works by interdisciplinary panels emphasizing process restoration. Large-scale river restoration came later to Europe, motivated by the EU Water Framework Directive (2000) requirements that member states implement measures to improve ecological status of degraded rivers. Interestingly, European approaches to restoration have often reflected a more nuanced understanding of process, including deliberate recreation of unstable braided channels, removal of bank protection, and reconnecting floodplains. In part this may reflect a reaction to the more thorough post-war channelization of rivers in western Europe. In part it may also reflect a greater influence of academic and research laboratories upon practitioners than in the US, where a strong anti-intellectual strain, cultural preference for easy fixes, and reluctance to conduct objective post-project assessments have contributed to the adoption of form-based approaches by many public agencies.

  2. Development and characterization of Al-Li alloys

    2006-01-01

    Increased strength to weight ratio of aluminium-lithium alloys has attracted material scientists to develop these for aerospace applications. But commercial scale production of these alloys has always been slow in view of difficulties encountered during addition of lithium and in ensuring homogeneous billet composition. A new technique of Li addition has been adapted, which gives maximum recovery of Li in the billet. Using this technique, aluminium-lithium alloys of two different grades for aerospace application were cast. Billets were hot forged and rolled to the thickness range of 3-4 mm and heat-treated for different temper conditions. Mechanical properties were evaluated in T6 (solution treated and artificial aged), T8 (solution treated, cold worked and artificial aged) and T4 (solution treated and natural aged) temper conditions. Both alloys exhibit a strong natural aging response. Reversion for short periods at 180 deg. C results in decrease of strength. With artificial reaging strength reaches above the T4 temper condition level. Characterization was carried out using optical microscope (OM) and scanning electron microscope (SEM). Experimental investigation shows that addition of lithium at high melt temperature gives lower recovery of Li, and use of impure aluminium adversely affects the mechanical properties of the alloy in all temper conditions

    . La construction proprement dite a demarre en juillet 1962, sous la double direction du Commissariat a l'Energie Atomique et de l'Electricite de France. La phase de genie civil s'achevera en 1964. L'enceinte etanche (dans laquelle, compte tenu du caractere prototype du reacteur, il a ete juge preferable de l'enfermer) a ete realisee en beton precontraint, methode apparaissant, comme particulierement rapide et elegante. La piece maitresse du reacteur est la cuve destinee a recevoir l'eau lourde. Cette cuve consiste en 2 fonds entretoises par 216 fourreaux et relies par une virole. Des problemes de soudure difficiles, compte tenu des specifications imposees ont ete resolus dans la fabrication des fonds. Un controle severe par radiographie et methodes ultrasoniques a ete adapte a une geometrie compliquee. Le montage de l'ensemble du bloc reacteur, et en particulier du reseau des tubulures destinees a alimenter les 216 canaux, a fait l'objet d'une etude detaillee et d'essais approfondis du type de raccord retenu. L'ensemble du circuit est realise en materiaux relativement classiques (aciers faiblement allies) dont la tenue au gaz carbonique a 500 deg. a ete verifiee. Le montage des circuits de CO{sub 2} et d'eau lourde debutera en octobre 1964. Des essais aerodynamiques ont ete effectues sur les soufflantes helico centrifuges (d'une puissance unitaire de 9 MW). L'adoption d'une pression aussi elevee que 60 kg/cm{sup 2} ne semble pas devoir poser de problemes nouveaux dans l'etancheite sur l'arbre des machines. Enfin le choix d'un type d'echangeur CO{sub 2} - eau vapeur a circulation forcee a amene l'Electricite de France a tester le fonctionnement et la stabilite d'un echangeur prototype dans ses installations d'essais.

    Full Text Available For more than one hundred years the construction system based on steel or composite steel -- concrete frames became one of the more utilized types of building in civil engineering domain. For an optimal dimensioning of the structure, the engineers had to found a compromise between the structural exigency for the resistance, stiffness and ductility, on one side, and architectural exigency on the other side. Three monotonic tests and nine cyclic tests according to ECCS loading procedure were carried out in Cluj Laboratory of Concrete. The tested composite columns of fully encased type were subject to a variable transverse load at one end while keeping a constant value of the axial compression force into them. An analytical interpretation is given for the calculus of column stiffness for the monotonic tests, making a comparation with the latest versions of the Eurocode 4 stiffness formula.

At the intermediate level of crystal plasticity, several effects need to be described accurately before considering the introduction of irradiation hardening mechanisms, such as the thermal activity of dislocations slip, the different mobilities between screw and edge dislocations at low temperature. These effects should be introduced in a crystal plasticity law used in finite-element simulations of polycrystalline aggregates. Accordingly, a new crystal plasticity law is proposed in this paper based on a critical analysis of previous numerical results obtained with a discrete dislocations dynamics code. (authors)

    The aim of this work is to study the micro mechanisms of deformation and rupture of an austeno ferritic stainless steel (Z 3 CND 22-10 M) with 33 % of ferrite. It is studied after ageing 1 000 h at 400 deg. C and 8 000 h at 350 deg. C and compared to the `as received` state. During ageing the ferritic phase undergoes microstructural evolutions which affects its properties. The two ageing treatments lead to roughly the same level of embrittlement. Microstructural characterisation shows that both phases percolate and exhibit orientation relationships close to Kurdjumov-Sachs ones. Mechanical properties of the steel were characterised for different ageing treatments at room temperature and at 320 deg. C. The interface is particularly strong and ensures the load transfer to ferrite even if this phase contains cleavage cracks. Moreover the interface does not oppose slip transmission which is instead controlled by localised glide in the ferritic phase. If activated slip systems of austenite are common with ferrite, slip transmission from austenite to ferrite indeed occurs through the=e interface. If they are not common, dislocations cross-slip back into the austenite. At 320 deg. C cross-slip occurs even far from the interface. Damage starts by nucleation in ferrite of cleavage cracks which propagate between austenite islands. Crack propagation is controlled by stretching of austenite ligaments. The material breaks by ductile tearing of austenite islands when the crack eventually percolates in the ferritic phase. The ductility of the material can be correctly describer using a simple model that takes into account the tearing-off the ductile-phase. (author). 153 refs.

    This study deals with crack propagation at 650 deg C on an austenitic stainless steel referenced by Z2 CND 17-12 (316L(NN)). It is based on an experimental work concerning two different cracked specimens: CT specimens tested at 650 deg C in fatigue, creep and creep-fatigue with load controlled conditions (27 tests), tube specimens containing an internal circumferential crack tested in four points bending with displacement controlled conditions (10 tests). Using the fracture mechanics tools (K, J and C* parameters), the purpose here is to construct a methodology of calculation in order to predict the evolution of a crack with time for each loading condition using a fracture mechanics global approach. For both specimen types, crack growth is monitored by using a specific potential drop technique. In continuous fatigue, a material Paris law at 650 deg C is used to correlate crack growth rate with the stress intensity factor range corrected with a factor U(R) in order to take into account the effects of crack closure and loading ratio R. In pure creep on CT specimens, crack growth rate is correlated to the evolution of the C* parameter (evaluated experimentally) which can be estimated numerically with FEM calculations and analytically by using a simplified method based on a reference stress approach. A modeling of creep fatigue growth rate is obtained from a simple summation of the fatigue contribution and the creep contribution to the total crack growth. Good results are obtained when C* parameter is evaluated from the simplified expression C*{sub s}. Concerning the tube specimens tested in 4 point bending conditions, a simulation based on the actual A 16 French guide procedure proposed at CEA. (authors) 104 refs.

    During service at high temperature (450 to 650 C), austenitic stainless steels are well known to present a risk of cracking near the welded junctions for times under the service life. This intergranular cracking in affected zones has been identified on titanium stabilized steels and is known as relief cracking by relaxation or reheat cracking. In order to control this cracking of welded junctions on titanium stabilized stainless steel AISI 321, a simulation of the affected zone has been realized. The results have been extended to non stabilized steels. (A.L.B.)

    Ion implantation in steels, although largely used to improve the properties of use, involves structural modifications of the surface layer, which remain still prone to controversies. Within this context, various elements (N, Ar, Cr, Mo, Ag, Xe and Pb) were implanted (with energies varying from 28 to 280 keV) in a 316LVM austenitic stainless steel. The implanted layer has a thickness limited to 80 nm and a maximum implanted element concentration lower than 10 % at. The analysis of the implanted layer by grazing incidence X ray diffraction highlights deformations of austenite lines, appearance of ferrite and amorphization of the layer. Ferritic phase which appears at the grain boundaries, whatever the implanted element, is formed above a given 'threshold' of energy (produced of fluency by the energy of an ion). The formation of ferrite as well as the amorphization of the implanted layer depends only on energy. In order to understand the deformations of austenite diffraction lines, a simulation model of these lines was elaborated. The model correctly describes the observed deformations (broadening, shift, splitting) with the assumption that the expansion of the austenitic lattice is due to the presence of implanted element and is proportional to the element concentration through a coefficient k'. This coefficient only depends on the element and varies linearly with its radius. (author)

    A model has been developed in order to simulate the ultrasonic inspection of steel tubes in the Vallourec control configuration. The model permits to simulate the control of steel tubes showing longitudinal defects located near the internal or external surface of tubes which appear during the rolling process. To detect this kind of defect, the probe is placed in an incident place perpendicular to the tube`s axis. The probe is in front of the external surface of the tube. The main characteristics of the model is to assume that the field radiated in the material does not depend on the probe`s position. This assumption permits to treat separately the field retracted in the material and the interaction between the defect and the ultrasonic beam. The focal plane is located in the material, so the plane waves approximation is applied where the waves front are assumed plane and parallel. The parallel refracted beam becomes divergent after reflection on the internal surface of tube. To treat the beam divergence, an amplitude weighting coefficient is then calculated by mean of the energy conservation of a tube of rays before and after reflection, following the Snell laws. This model can predict the edge diffraction echoes, the echoes issued from the corner effect, and also the mode conversion echoes. It has been validated on artificial notches, and on some natural defects. A comparison between experimental and modelling results shows a good agreement. (author) 39 refs.

    The heat affected zone (HAZ) of titanium stabilised austenitic stainless steel welds (AISI 321) may exhibit a serious form of intercrystalline cracking during service at high temperature. This type of cracking, called 'stress relief cracking', is known to be due to work hardening but also to ageing: a fine and abundant intragranular Ti(C,N) precipitation appears near the fusion line and modifies the mechanical behaviour of the HAZ. This study aims to better know the accused mechanism and to succeed in estimating the risk of such cracking in welded junctions of 321 stainless steel. To analyse this embrittlement mechanism, and to assess the lifetime of real components, different HAZ are simulated by heat treatments applied to the base material which is submitted to various cold rolling and ageing conditions in order to reproduce the HAZ microstructure. Then, we study the effects of work hardening and ageing on the titanium carbide precipitation, on the mechanical (tensile and creep) behaviour of the resulting material and on its stress relief cracking sensitivity. It is shown that work hardening is the main parameter of the mechanism and that ageing do not favour crack initiation although it leads to titanium carbide precipitation. The role of this precipitation is also discussed. Moreover, a creep damage model is identified by a local approach to fracture. Materials sensitive to stress relief cracking are selected. Then, creep tests are carried out on notched bars in order to quantify the intergranular damage of these different materials; afterwards, these measurements are combined with calculated mechanical fields. Finally, it is shown that the model gives good results to assess crack initiation for a compact tension (CT) specimen during relaxation tests, as well as for a notched tubular specimen tested at 600 deg. C under a steady torque. (author)

    27 VVER 440 pressurised water reactors operate in former Soviet Union and in Eastern Europe. The pressure vessel, is made of Cr-Mo-V steel. It contains a circumferential arc weld in front of the nuclear core. This weld undergoes a high neutron flux and contains large amounts of copper and phosphorus, elements well known for their embrittlement potency under irradiation. The embrittlement kinetic of the steel is accelerated, reducing the lifetime of the reactor. In order to get informations on the microstructure and mechanical properties of these steels, base metals, HAZ, and weld metals have been characterized. The high amount of phosphorus in weld metals promotes the reverse temper embrittlement that occurs during post-weld heat treatment. The radiation damage structure has been identified by small angle neutron scattering, atomic probe, and transmission electron microscopy. Nanometer-sized clusters of solute atoms, rich in copper with almost the same characteristics as in western pressure vessels steels, and an evolution of the size distribution of vanadium carbides, which are present on dislocation structure, are observed. These defects disappear during post-irradiation tempering. As in western steels, the embrittlement is due to both hardening and reduction of interphase cohesion. The radiation damage specificity of VVER steels arises from their high amount of phosphorus and from their significant density of fine vanadium carbides. (author)

    It is in the framework of the research programs on nuclear reactors (generation IV) that the martensitic steels containing 9-12% Cr are studied by the CEA. Most of the structures for which they are considered will be solicited in fatigue-creep at high temperature (550 C). The aim of this work is to understand and model the cyclic behaviour and the damage of these materials. The proposed modelling are based on detailed observations studies (SEM, TEM, EBSD...). The cyclic softening is attributed to the growth of the microstructure. A micro-mechanical model based on the physical parameters is proposed and leads to encouraging results. The damage results of interactions between fatigue, creep and oxidation. Two main types of damage are revealed. A model of anticipation of service time is proposed and gives very satisfying results. The possible extrapolations are discussed. (O.M.)

    From all the methods possible for controlling thin cans the one chosen, for numerous reasons, vas that making use of ultrasonic techniques. A method has been developed which should make it possible to carry out a rapid and efficient industrial control of canning tubes, The reasons for the choice of the ultrasonic method are given in detail, together with the principles of the method and the actual control parameters. In the present state of our research, it should be possible to control at least 50 000 tubes a year. Improvements brought about in the details of the control technique itself should make it possible to increase this rate considerably.

    The austenitic-ferritic steels are used in the PWR primary cooling system. At the running temperature (320 C), they are submitted to a slow aging, which leads to the embrittlement of the ferritic phase. This embrittlement leads to a decrease of the mechanical properties, in particular of the crack resistance of the austenitic-ferritic steels. The damage and rupture of the austenitic-ferritic steels have been approached at the ENSMP by the works of P. Joly (1992) and of L. Devilliers-Guerville (1998). These works have allowed to reveal a damage heterogeneity which induces a strong dispersion on the ductilities and the toughnesses as well as on the scale effects. Modeling including the damage growth kinetics measured experimentally, have allowed to verify these effects. Nevertheless, they do not consider the two-phase character of the material and do not include a physical model of the cleavage cracks growth which appear in the embrittled ferrite. In this study, is proposed a description of the material allowing to treat these aspects while authorizing the structure calculation. In a first part, the material is studied. The use of the ESBD allows to specify the complex morphology of these steels and crystal orientation relations between the two phases. Moreover, it is shown that the two phases keep the same crystal orientation in the zones, called bicrystals, whose size varies between 500 {mu}m and 1 mm. The study of the sliding lines, coupled to the ESBD, allows to specify too the deformation modes of the two phases. At last, tensile and tensile-compression tests at various deformation range are carried out to characterize the macroscopic mechanical behaviour of these materials. Then, a micro-mechanical modeling of the material behaviour is proposed. This one takes into account the three scales identified at the preceding chapter. The first scale, corresponding to the laths is described as a monocrystal whose behaviour includes both an isotropic and a kinematic strain hardening. In the second one, the bicrystal is represented either by a finite element method on a representative pattern or by a phenomenological mean fields model adjusted on the finite element method. The third one, the poly-crystal represents the aggregate of bicrystals, and is modelled by polycrystals classical models. The different parameters of the model are identified on monotonous tensile tests and on tensile-compression tests. The damage is then approached. The experiments show that the cleavage cracks appear preferentially at the intersection of the two gliding bands of the ferrite. These observations lead to propose a Cottrell model to represent the cleavage initiation. This model is then extrapolated in order to take into account the growth kinetics. Then is defined a density of the cleavage cracks for each of the three ferrite cleavage plans. The damage is by consequence anisotropic and can be represented by a damage tensor of the fourth order. An easy coupling model taking into account the damage tensor is proposed. At last, the rupture is represented by the Thomasen criteria. The damage model on the whole is introduced too into the calculation code. (O.M.)

    The study deals with crack initiation at 600 and 650 degrees Celsius, on an austenitic stainless steel referenced by Z2 CND 17 12. The behaviour laws of the studied plate were update in comparison with existing data. Forty tests were carried out on CT specimens, with continuous fatigue with load or displacement controlled, pure creep, pure relaxation, creep-fatigue and creep-relaxation loadings. The practical initiation definition corresponds to a small crack growth of about the grain size. The time necessary for the crack to initiate is predicted with fracture mechanics global and local approaches, with the helps of microstructural observations and finite elements results. An identification of a `Paris`law` for continuous cyclic loading and of a unique correlation between the initiation time and C{sup *}{sub k} for creep tests was established. For the local approach, crack initiation by creep can be interpreted as the reaching of a critical damage level, by using a damage incremental rule. For creep-fatigue tests, crack growth rates at initiation are greater than those of Paris`law for continuous fatigue. A calculation of a transition time between elastic-plastic and creep domains shows that crack initiation can be interpreted whether by providing Paris`law with an acceleration term when the dwell period is less than the transition time, or by calculating a creep contribution which relies on C{sup *}{sub k} parameter when the dwell period and/or the initiation times are greater than the transition time. Creep relaxation tests present crack growth rates at initiation which are less than those for `equivalent` creep-fatigue tests. These crack growth rates when increasing hold time, but also when temperature decreases. Though, for hold times which are important enough and at lower temperature, there is no effect of the dwell period insofar as crack growth rate is equal to continuous fatigue Paris law predicted ones.

    Polarization and electrochemical impedance spectrometry curves are presented and discussed. These curves make it possible to ascertain the corrosion domains and to compare the slow and fast kinetics (voltammetry) of different stainless steel alloys. These corrosion kinetics, the actual or simulated tritiated water redox potentials, and the corrosion potentials provide a classification of the steels studied here: 316L, Hastelloy, Maraging, Inconel 600, Elgiloy, carbon steel and TiN and NiCr deposits. From the results it can be concluded that Hastelloy and Elgiloy have the best corrosion resistance. (author). 49 refs., 695 figs., tabs.

    The investigation of the effects of different thermomechanical treatments on the microstructure of alloys 8090 and 8091 (Al-Li-Cu-Mg{sub Z}r) is the aim of the present work. In this context, the intervention of static recrystallization during solution treatment after hot working is the determining factor on the final microstructure of products in form of plates. The results could reveal that the rolling temperature is a very important variable if microstructural control is to be achieved in these alloys. (author) 9 refs., 6 figs.
