    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.

    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 study is a contribution to the prediction of flow fracture toughness of low alloy steel and to a better knowledge of fracture behavior in the ductile to brittle transition region. Experiments were performed on a nozzle cut-off from a pressurized water reactor vessel made of steels A508C13 type steel. Axisymmetrical notched specimens were tested to study the fracture onset in a volume element while pre-cracked specimens were used to investigate cleavage fracture after stable crack growth. Systematic observations of fracture surfaces showed manganese sulfide inclusions (MnS) at cleavage sites or in the vicinity. The experimental results were used for modelling by the local approach to fracture. In a volume element the fracture is described by an original probabilistic model. This model is based on volume fraction distributions of MnS inclusions gathered in clusters and on the assumption of a competition without interaction between ductile and cleavage fracture modes. This model was applied to pre-cracked specimens (CT specimens). It is able to describe the scatter in the toughness after a small stable crack growth if a temperature effect on the cleavage stress is assumed. So, the modelling is able to give a lower bound of fracture toughness as a function of temperature. (author) 100 refs.

    The objective of this study is to take into account the effect of plasticity mechanisms on the ductile/brittle transition in low alloy steels of PWR reactor vessels. A crystalline plasticity model, describing the effect of temperature on the behaviour, has been implemented in a large transformation frame. The material parameters of the model have been determined experimentally and from mechanical tests using an inverse method. Simulations of polycrystalline aggregates have been performed with imposed triaxiality. The study of local heterogeneities shows that the distribution of main stress can be modeled using a distribution of extreme values of first species (Gumbel) and that the parameters of this distribution can be simply described as a function of {sigma}{sub mises} (the average equivalent stress) and T (temperature). This approach will allow to introduce the effect of these heterogeneities in a local approach criterion of rupture. (J.S.)

    This report deals chiefly with the treatment of binary alloys (UAI, UMo, UZr, UCr, USi) with a low concentration of the additional element ({<=}2 per cent). The investigation was pursued with a view to the continued utilisation, with a minimum of modification, of the existing plants for treatment of non-alloyed irradiated uranium. In the first part, the usual process for the treatment of irradiated uranium by solvent extraction is briefly recalled. The second part is devoted to a study of the selective dissolution of the canning around certain of these alloys. The third part gives the behaviour of these different alloys at various phases of the usual treatment: a) dissolution; b) extractions; c) final treatment of fission products; d) final purification of plutonium. To conclude, possible alloys are classed as a function of their repercussions on the normal treatment.

    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.)

    Imagine you are a grad student, at your first conference, and a prominent senior scientist shows interest in your work, and he makes things get way too personal? What would you do? Would you report it? Or would you decide, after a few other instances of harassment, that maybe you shouldn't pursue astronomy? Harassment is under-reported, the policies can be difficult to understand or hard to find, and it can be very intimidating as a young scientist to report it to the proper individuals. The Astronomy Allies Program is designed to help you with these sorts of problems. We are a group of volunteers that will help by doing the following: provide safe walks home during the conference, someone to talk to confidentially, as an intervener, as a resource to report harassment. The Allies are a diverse group of scientists committed to acting as mentors, advocates, and liaisons. The Winter 2015 AAS meeting was the first meeting that had Astronomy Allies, and Astronomy Allies provided a website for information, as well as a twitter, email, and phone number for anyone who needs our help or would like more information. We posted about the Astronomy Allies on the Women In Astronomy blog, and this program resonates with many people: either they want to help, or they have experienced harassment in the past and don't want to see it in the future. Harassment may not happen to most conference participants, but it's wrong, it's against the AAS anti-harassment policy ( http://aas.org/policies/anti-harassment-policy ), it can be very damaging, and if it happens to even one person, that is unacceptable. We intend to improve the culture at conferences to make it so that harassers feel they can't get away with their unprofessional behavior.

    SUMMARY Providing a community that is committed to standards, diversity, and enhancement of the academic environment is often difficult. Offering an Allies or Safe Zone program is among of the first steps an institution can take to achieve a community that embraces diversity and creates a learning environment that is accepting of lesbian, gay, bisexual and transgendered individuals. While there are many opportunities in institutional group settings to address these issues, they often go either unnoticed or untapped. How can being an ally impact the greater institutional environment? This paper will discuss the campus environment for LGBT students, examine existing Allies and Safe Zone programs, and offer a framework to assist program coordinators and participants in establishing comprehensive programs to change the campus climate and develop institutional environments that are gay affirmative.

    In low copper steels for nuclear reactor pressure vessel, point defect clustering plays an important role in hardening. These clusters are very small and invisible by transmission electron microscopy. In order to study the hardening component which results from the clustering of freely migrating point defects, we irradiated in a high voltage electron microscope Fe, the FeCu{sub 0.13%}, FeP{sub 0.015%} and FeN{sub 33ppm} alloys and the complex FeMn{sub 1.5%}Ni{sub 0.8%}Cu{sub 0.13%}P{sub 0.01%} alloy the composition of which is close to the matrix of pressure vessel steel. We studied the nucleation of dislocation loops and their growth velocity. The observations and the analyses have shown that in the complex model alloy, the interstitial dislocation loops are smaller and their density is more important than for the others alloys. The diffusion coefficients of interstitials and vacancies are obtained with the help of a simplified model. The densities of dislocation loops and their growth velocities obtained experimentally are reproduced by means of a cluster dynamics model we have developed. This is achieved self-consistently by using as a first trial the approximated coefficients obtained with the simplified model. The results of calculations have shown that the binding energy of di-interstitials must be very important in the binary iron alloys and only 0.95 eV in iron. Copper, nitrogen and phosphorus stabilize di-interstitials in iron. Finally the distribution of interstitial loops at 290 deg C and at 2.10{sup -9} dpa/s is calculated with the diffusion coefficient of point defects adjusted in FeCu. A distribution of small loops appears which gives an increase of hardening estimated to 10 Hv instead of 33 Hv experimentally observed. This low value can be improved by assuming in agreement with molecular dynamics simulations that a little fraction of di-interstitials is created at 2.5 MeV. (author) 111 refs.

    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.

    Allied health professionals in nutrition and medical dietetics, occupational therapy, physical therapy, and speech-language pathology and audiology play both unique and key cross-cutting roles in the furtherance of clinical research. Clinical research in nutrition and medical dietetics uniquely focuses on food nutrient intake and the metabolic utilization of nutrients. Clinical research in occupational therapy has a special focus on the relationship of impairment to disability, the adaptation to disability and the maximization of function. Physical therapy clinical research uniquely targets movement dysfunction and its evaluation and treatment within the context of quality and effective care. Clinical research in speech-language pathology and audiology is singular in its focus on deafness and hearing disorders, voice, speech, language and related disorders, and intersections among these and other neurological and physical conditions. Thus, all of these disciplines are making unique contributions to clinical research. Clinical research in these allied health professions is much more than the above specific foci. Inasmuch as these disciplines are rooted in practice, their contributions to research are inherently clinical. Many, if not most, of these contributions represent further validations of clinical practice or its underlying knowledge base. This means that, at a macro level, clinical research in allied health is very much "applied" research. Within allied health clinical research, this emphasis is redoubled at the "person," or individual level, where considerable attention is given to concepts of function and effectiveness. Clinical research in allied health has played a key cross-cutting role through its emphasis on collaboration. Possibly due to their professional maturation within multidisciplinary academic units, allied health professionals have demonstrated a level of comfort with multidisciplinary and interdisciplinary collaborations unique within many

This provides a metric on which Australian institutions and disciplines are ranked for international competitiveness. This paper explores the issues surrounding the ERA rankings of allied health journals in Australia.Methods: We conducted a broad search to establish a representative list of general allied health and discipline-specific journals for common allied health disciplines. We identified the ERA rankings and impact factors for each journal and tested the congruence between these metrics within the disciplines.Results: Few allied health journals have high ERA rankings (A*/A, and there is variability in the impact factors assigned to journals within the same ERA rank. There is a small group of allied health researchers worldwide, and this group is even smaller when divided by discipline. Current publication metrics may not adequately assess the impact of research, which is largely aimed at clinicians to improve clinical practice. Moreover, many journals are produced by underfunded professional associations, and readership is often constrained by small numbers of clinicians in specific allied health disciplines who are association members.Conclusion: Allied health must have a stronger united voice in the next round of ERA rankings. The clinical impact of allied health journals also needs to be better understood and promoted as a research metric.Keywords: allied health, research impact, publication metrics

    Full Text Available Sexism is often expressed in subtle and ambiguous ways, causing targets to doubt their own capabilities or to show stereotype-confirming behavior. 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.

  10. Overview of allied health personnel shortages.

    Elwood, T W

    1991-01-01

    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

  14. Strategies for Engaging Men as Anti-Violence Allies: Implications for Ally Movements

    Directory of Open Access Journals (Sweden)

    Erin Casey

    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.

    The concept retained for high level and years living radioactive waste disposal is the underground storage. It is then necessary to know the behaviour in time (about 10000 years) of the different constituent elements of the containment. The storage site chosen is the Bures' ones, presenting a clay formation at 600 m of depth. Each compartment is separated of a sufficient distance in order to profit of the thermal dispersion effect in the rock for optimizing the cooling of the package. In this work, has been used an unalloyed steel sur-container. The aim is to understand the resistance of the material under corrosion and loading, and particularly the stress corrosion which is a particular case of cracking assisted by environment. The material studied is a weld of two unalloyed steels obtained by electron beam. Slow traction tests have been carried out in an autoclave in the following experimental conditions: interstitial water in equilibrium with a helium-CO{sub 2} mixture 5.4 per thousand under 50 bar and at a temperature of 90 C. The results show an influence of the hydrogen corrosion on the mechanical behaviour of the material and particularly a decrease of the size of the reduction in area, which is practically unexisting in the case of the melted zone. These results are explained into details. (O.M.)

    I was fortunate to enjoy the advice of K. G. Emeleus during my graduate studies and for many years afterwards. He introduced me to the papers of Will Allis and later I was privileged to correspond with Professor Allis. At this time I had moved from the Queens university environment to work at a large Air Force base. There I have worked with a lot of smart people, including several who also come to the GEC each year to be refreshed and calibrated. A personal overview is presented on a few of the many roles that atomic, molecular and optical physics, including gaseous electronics, play in programs of the Air Force Research Laboratory and subsequently on AF systems and operations. While there have been misses, overall there have been many successes with impacts that provide more effective systems, as recent experiences have demonstrated. Some example studies, involving primarily electron collision physics, successful and unsuccessful in being chosen for application, are discussed.

  20. Influence de la composition chimique et de la microstructure sur le dégazage de l'hydrogène des aciers inoxydables austénitiques destinés à l'ultravide

    CERN Document Server

    Reinert, Marie-Pierre

    Dans les installations métalliques sous ultravide, l'hydrogène est le principal constituant de l'atmosphère résiduelle. Le flux de dégazage d'une tôle en acier inoxydable austénitique, matériau fréquemment utilisé en technologie du vide, après un étuvage sous vide, est typiquement de quelques 10-12 Torr.1/cm2.s, et est constitué principalement d'hydrogène. Dans le cadre de cette étude, un appareillage de thermodésorption sous ultravide a été conçu et mis au point pour étudier les phénomènes d'adsorption, de diffusion et de piégeage de l'hydrogène résiduel dans les aciers inoxydables austénitiques. Différents aciers ont été étudiés: l'acier 316L (avec trois modes d'élaboration différents), l'acier 316LN et d'autres aciers stabilisés au titane ou au niobium. La microstructure et la couche d'oxyde de ces aciers ont été caractérisées à l'état de réception et pendant les cycles de thermodésorption.

  1. Fissuration en relaxation des aciers inoxydables austénitiques au voisinage des soudures

    Science.gov (United States)

    Auzoux, Q.; Allais, L.; Gourgues, A. F.; Pineau, A.

    2003-03-01

    Des fissures intergranulaires peuvent se développer au voisinage des soudures des aciers inoxydables austénitiques lorsqu'ils sont réchauffés dans le domaine de température compris entre 500^{circ}C et 700^{circ}C. A ces températures, les contraintes résiduelles post-soudage se relaxent par déformation viscoplastique. Il peut arriver que ces zones proches de la soudure soient tellement fragiles, qu'elles ne puissent accommoder cette faible déformation. Afin de préciser quelles peuvent être les modifications microstructurales qui conduisent à une telle fragilisation, on a examiné les microstructures de ces zones et révélé ainsi un écrouissage résiduel, responsable d'une forte élévation de la dureté. On a pu reproduire par hypertrempe puis laminage entre 400^{circ}C et 600^{circ}C une microstructure similaire. Des essais mécaniques (traction, fluage, relaxation, sur éprouvettes lisses et pré-fissurées) ont été réalisés à 550^{circ}C et à 600^{circ}C sur ces zones affectées simulées et sur un état de référence hypertrempé. Ils ont montré que l'écrouissage diminuait la ductilité dans le domaine de rupture intergranulaire, sans modifier qualitativement le mécanisme d'endommagement. Pendant la pré-déformation les incompatibilités de déformation entre grains conduiraient à l'existence de contraintes locales élevées qui favoriseraient la germination des cavités intergranulaires.

    Many international declarations recognize citizen participation as an important driver of success for health policy; however, in most countries the implementation of this principle has been delayed. Yet well-known phenomena, like ageing and incurred costs, should motivate decision makers to rely more on citizens and make them allies of the system, giving them power and responsibility. Citizens can first exercise this responsibility within the areas of prevention and health promotion. This responsibility then expands to include mutual assistance between community members. It is called upon in the definition of new social norms. It is recognized by the participation of citizens in health care decision-making bodies. Lastly, this responsibility applies when the time comes to choose which health services will be covered by the public system and which will be sent on to private insurers. The reasons to create a space for citizens are many. The methods to do it exist. What is needed is political willpower and means.

    Faculty research productivity in colleges of allied health has often been discussed in the literature over the last five years. Articles have focused on the problem of faculty research productivity from various viewpoints, but none have used a theoretical framework to analyze the problem. The total quality management (TQM) framework is currently being used in health care to improve quality and productivity. This article uses the TQM framework to synthesize literature concerning faculty research productivity and verifies the current relevance of synthesis findings using an allied health faculty survey. These analyses show that the TQM framework is useful in suggesting ways to increase faculty research productivity in colleges of allied health.

    A new surface treatment technique by primary explosive was used on a 316L type austenitic stainless steel. Two explosive compositions, inducing a pressure of 1 GPa and 4 GPa respectively, were deposited in a thin layer on plane samples. The detonation induced effects have been characterized by different techniques. The surface roughness increases with the applied pressure, but remains lower than that obtained after shot peening. The microbardness profiles along a direction perpendicular to the treated surface and the microstructural study exhibit a marked hardening on several hundred micrometers associated with a profuse twinning. Moreover, for the 4 GPa pressure a very thin surface layer of fine recrystallized grains appears. In both cases, tensile residual stresses are measured at the surface and compressive stresses beyond 10~μm. The microstructure in the surface layers results of a noticeable thermal effect. The wear resistance of this stainless steel is improved by a factor 10 to 200 depending on the treatment conditions. Une technique de traitement de surface utilisant un explosif primaire a été utilisée sur un acier inoxydable austénitique de type 316L. Deux compositions explosives délivrant des pressions respectives de 1 GPa et 4 GPa ont été déposées en couche mince sur des échantillons plans. Les effets induits par la détonation ont été caractérisés par différentes techniques. La rugosité en surface augmente avec la pression appliquée mais reste très inférieure à celle obtenue après grenaillage. Les profils de microdureté suivant un axe perpendiculaire à la surface traitée et l'étude microstructurale montrent un écrouissage marqué sur quelques centaines de micromètres associé à un maclage important auquel s'ajoute, pour la pression de 4 GPa, une fine recristallisation en surface. Dans les deux cas, les contraintes résiduelles sont de tension en surface et passent en compression au-delà de 10~μm. La microstructure des

    Lam, Raymond; Kruger, Estie; Tennant, Marc

    2013-01-01

    This study aims to provide a comparative analysis of the Chronic Dental Disease Scheme (CDSS) and the Allied Health Profession (AHP) program as they related to the greater Enhanced Primary Care Scheme introduced by the Australian Government to manage patients with chronic and complex diseases. A retrospective analysis of data pertaining to Medicare items related to dentistry and the allied health professions were extracted from the Medicare Benefits Schedule database online, and formed the basis of this study. The highest proportion of services was provided in the state of New South Wales. There appears to be synergy in the utilisation of services with jurisdictions either overutilising or underutilising services. Costs to the Enhanced Primary Care Scheme under the CDSS model (fee for service) were up to 40 times more expensive compared with the AHP model (fee per visit). Costs and treatment associated with the CDSS experienced an increase of 13350% during the period 2007-08, coincident with an increase in subsidization. Reconstructive dentistry accounted for the majority of the increase. Gender disparities in dentistry were less distinct when compared with AHPs and were postulated to be due to males presenting with conditions that were more progressive requiring more invasive treatment. A comparative analysis indicates significant differences in costs, nature of treatment and the manner of remuneration between dentistry and the AHPs. A fee for service schedule as evidenced by the CDSS is dependent on the degree of financial incentive as indicated by patterns in utilisation over time. The amount of treatment considered necessary may be influenced by the level of subsidy with treatment that may not reflect disease management. The AHP model, which is based around a fee for visit schedule, is not without its deficiencies but has not experienced significant rises in cost compared with the CDSS. PMID:22951045

    Imagine you are a grad student, at your first conference, and a prominent senior scientist shows interest in your work, and he makes things get way too personal? What would you do? Would you report it? Or would you decide, after a few other instances of harassment, that maybe you shouldn't pursue astronomy? Harassment is under-reported, the policies can be difficult to understand or hard to find, and it can be very intimidating as a young scientist to report it to the proper individuals. The Astronomy Allies Program is designed to help you with these sorts of problems. We are a group of volunteers that will help by doing the following: provide safe walks home during the conference, someone to talk to confidentially, as an intervener, as a resource to report harassment. The Allies are a diverse group of scientists committed to acting as mentors, advocates, and liaisons. The Winter 2015 AAS meeting will be the first meeting that has Astronomy Allies, and Astronomy Allies will provide a website for information, as well as a twitter, email, and phone number for anyone who needs our help or would like more information. We posted about the Astronomy Allies on the Women In Astronomy blog, and this program resonates with many people: either they want to help, or they have experienced harassment in the past and don't want to see it in the future. Harassment may not happen to most conference participants, but it's wrong, it's against the AAS anti-harassment policy ( http://aas.org/policies/anti-harassment-policy ), it can be very damaging, and if it happens to even one person, that is unacceptable. We intend to improve the culture at conferences to make it so that harassers feel they can't get away with their unprofessional behavior.

    Microbiologically Influenced Corrosion (M.I.C.) studied since the beginning of this century, is responsible for the degradation of many metallic equipments. This study is a review of results dealing with M.I.C. on several types of steels as: carbon steels, stainless steels, welded steels and covered steels. M.I.C. occurs only in presence of a biofilm. The first part of this study describes chemical and physical factors involved in its development, technical methods for studying biofilms, and its contribution in the corrosion process. The second part is devoted to the study of M.I.C. cases linked with metal nature and different aqueous environments and the last part reviews the mainly mecanisms of biocorrosion. La Corrosion Influencée par les Micro-organismes (C.I.M.) ou biocorrosion, phénomène étudié depuis le début du siècle, est responsable de la dégradation d'un grand nombre d'ouvrages métalliques. Cette étude a pour but de faire le point des connaissances sur la corrosion influencée microbiologiquement de divers types d'aciers au carbone, d'aciers inoxydables, d'assemblages soudés et d'aciers revêtus. La C.I.M. n'apparaît qu'en présence d'un biofilm. La première partie de cette étude décrit les facteurs physico-chimiques impliqués dans la formation du biofilm, ces moyens d'études ainsi que son action dans le processus de biocorrosion. La seconde partie est consacrée à la description des cas de biocorrosion classés en fonction de la nature des métaux et des milieux avec lesquels ils sont en contact. La dernière partie de ce document passe en revue les principaux mécanismes de biocorrosion décrits.

Shopian, recently created hilly district of Kashmir valley, Jammu and Kashmir is surrounded by the lofty mountains of Pir-Panjal range. More than half area of district is occupied by different forests, subalpine, alpine and mountainous zones. Great altitudinal variation, adequate rainfall, high forest cover, large number of streams, springs and topographic variations render the district worthy for supporting rich fern flora. Therefore, the current study was aimed to undertake in-depth systematic survey of different habitats of Shopian for the collection of diversity of pteridophytes. Specimens were collected during 2010, 2011 and 2012 growing seasons from June to November. A total 81 species of ferns and fern allies belonging 27 genera and 11 families were reported. The dominant families of the region are Dryopteridaceae (25 species followed by Woodsiaceae (16 species, Aspleniaceae (13 species and Pteridaceae (12 species. Similarly, the dominant genera collected from here are Dryopteris (14 species, Asplenium (13, Polystichum (11 species and Athyrium (6 species. A list of the fern and fern allies, along with update nomenclature, their selected Synonym, diagnostic features, distributional and ecological notes have been provided here.

    In the nuclear energy industry, the use of components made of austenitic stainless steel is widely spread, because of its specific thermal properties. The assembly of these pressure vessels and piping by welding processes often requires surface mechanical operations. These operations aim at hardening surfaces and lowering roughness. Nevertheless the main effect of these operations is the occurrence of residual stresses which can have positive or negative effects on the fatigue life. In this study, we focus on the evaluation and relaxation of residual stresses level on AISI 304L austenitic stainless steel tubular welded structures. Some of these rings are base metal rings (which stand as reference), the rest presents a longitudinal and symmetrical Y-weld joint, with or without grinding. Surface residual stresses, and their relaxation, were determined by using the X-ray diffraction method.

    Revised accreditation standards for dental and dental hygiene education programs have increased emphasis on faculty development that can improve teaching and learning, foster curricular change including use of teaching and learning technologies, and enhance retention and satisfaction of faculty. The American Dental Education Association (ADEA) and Academy for Academic Leadership (AAL) established the Institute for Allied Health Educators (IAHE) in 2007 to address faculty development needs for allied dental and allied health educators. In 2009, it was transitioned to an online program, which resulted in increased enrollment and diversity of participants. After seven years, a comprehensive program evaluation was warranted. The authors developed an online questionnaire based on Kirkpatrick's four-level model of training evaluation; for this study, levels one (satisfaction), two (knowledge and skill acquisition), and three (behavior change) were examined. Of the 400 program participants invited to take part in the study, a 38% response rate was achieved, with the majority indicating full-time faculty status. Nearly all (95-97%) of the respondents agreed or strongly agreed the program contributed to their teaching effectiveness, and 88-96% agreed or strongly agreed it enhanced their knowledge of educational concepts and strategies. In addition, 83% agreed or strongly agreed the program helped them develop new skills and confidence with technology, with 69% agreeing or strongly agreeing that it helped them incorporate technology into their own educational setting. Nearly 90% were highly positive or positive in their overall assessment of the program; 95% indicated they would recommend it to a colleague; and 80% agreed or strongly agreed they had discussed what they learned with faculty colleagues at their home institutions who had not attended the program. Positive findings from this evaluation provide evidence that the IAHE has been able to meet its goals.

    2001-01-01

    A ten year review of developments in the organisation and management of allied health services in Australian acute care public hospitals reveals a steady transformation away from a medically managed universal model towards more complex and contested models of governance. This article revisits early observations about the reorganisation of allied health services and presents more recent research findings to guide managerial decision-making about restructuring the diverse disciplines that constitute allied health. A new organisational model "integrated decentralization" is presented as an approach to managing allied health services which accommodates multiple stakeholder demands in the context of New Public Management (NPM) related reforms. The focus on the institutional level is complemented by examining developments in the profile and activity of allied health at the regional, state and national levels to present a more comprehensive picture of change over the decade of the 1990s.

  7. Characteristics of patients with measles admitted to allied hospital rawalpindi

    International Nuclear Information System (INIS)

    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)

    Sex and gender differences in rehabilitation are important because more than half of patients seen by allied health professionals are female. Sex- and gender-specific curricula should be audited to enhance interprofessional education in women's health. The research question was: What is the extent of information about sex and gender differences that is included in selected allied health professions curricula? Student scholars from allied health programs audited courses in real time for references to sex and gender differences. The data were analyzed using content analysis. The emphasis of instruction included primarily statements of facts for the physical and occupational therapy programs and brief discussions in the athletic training program. There was a significant difference among the categories of emphasis for the programs (X2 = 391.23, panalysis of sex and gender differences in selected allied health professions. No textual inferences were made, but the study reported on the topics discussed and the extent of the sharing of information. PMID:27585612

  11. Effect of Impurities and Cerium on Stress Concentration Sensitivity of Al-Li Based Alloys

    Institute of Scientific and Technical Information of China (English)

    孟亮; 田丽

    2002-01-01

    A notch sensitivity factor was derived in order to evaluate the stress concentration sensitivity of Al-Li based alloys. The factor values for the Al-Li alloy sheets containing various contents of impurities and cerium addition were evaluated by determining the mechanical properties. It is found that the impurities Fe, Si, Na and K significantly enhance the stress concentration sensitivity of the alloys 2090 and 8090, whereas cerium addition reduces the stress concentration sensitivity to a certain degree for the high strength alloys. However, an excess amount of cerium addition in the high ductility alloy 1420 can significantly increase the stress concentration sensitivity. As compared with conventional aluminum alloys, the Al-Li based alloys generally show high stress concentration sensitivity. Therefore, a special attention must be paid to this problem in the practical application of Al-Li based alloys.

    1984-09-01

    The use of a coordinated team of allied health professionals (AHPs) to treat patients with rheumatoid arthritis assigned to experimental groups (EG) and comparison groups (CG) was assessed. The EG patients were evaluated regularly by each AHP team member, whereas CG patients were seen by AHPs only upon referral. Of the 10 EG and 13 CG patients who remained in the study for 2 years, the EG patients initially exhibited somewhat greater disease activity than CG (as reflected by erythrocyte sedimentation rate and duration of morning stiffness). After 2 years, EG patients demonstrated less disease activity than at the outset, whereas CG patients either showed little change in these parameters or deteriorated during the study. Grip strength, which was initially similar in the two groups, improved in EG patients but decreased in CG patients, so that after 2 years a significant difference was noted between the two groups (p less than .05). Tendency to lose hand range of motion was also greater in CG than in EG patients. Some EG patients showed improvement in finger flexion deformities during the study. Furthermore, EG patients showed a greater tendency to acquire positive attitudes regarding themselves and family relationships. These results suggest that ongoing "team care" may be more efficacious than episodic use of AHPs in management of patients with mild rheumatoid arthritis.

    2014-01-01

    In order to determine Caucasian allied health student racial attitudes towards the African American population, students and faculty of a Southern school of allied health professions were surveyed using the Racial Argument Scale (RAS). A one way ANOVA found a significant difference between allied health programs, p = .008, and post hoc testing found the Occupational Therapy Program's scores to be significantly lower (less negative towards Blacks) than the Physical Therapy and Physician Assistant Program's scores (p = .008 and p = .041 respectively). Student scores overall were significantly higher than faculty scores on the RAS (p = .014). The Speech-Language Pathology, Physician Assistant, and Physical Therapy Programs' scores as well the overall allied health student scores were found to be significantly higher than the population mean, thus indicating a higher negativity towards African Americans. The overall results of this study indicate that negative racial bias may be a serious problem in some allied health programs. Future instruction in cultural competency in allied health programs should address racial bias specifically, taking into account cognitive-perceptual errors that may perpetuate negative racial attitudes.

This can be defined as the use of drugs to treat self-diagnosed disorders or symptoms, or the intermittent or continued use of a prescribed drug for chronic or recurrent disease or symptoms. High level of education and professional status has also been mentioned as predictive factors for self-medication. Students from the allied and nonallied health institutions of the University of Santo Tomas were assessed for the factors of self-medication practices.A total of 66 graduating students were asked to accomplish the questionnaire. To ensure valid responses, the researchers supervised the respondents on accomplishing the questionnaires. Mean and range summarized the age while counts and percentages summarized the gender, school, practice of selfmedication, therapeutic classes, health conditions, reasons and sources of self-medication. A total of 55 reported that they practice self-medication. On the total 66 respondents practicing self-medication is antibiotics, anti-allergic and antihistamine, and decongestants. The 55 respondents documented headache to be the most self-treated health condition followed by cough and cold, toothache, muscle pain pimples, back/chest pain, dizziness, and diarrhea/constipation.

  19. Using staffing ratios for workforce planning: evidence on nine allied health professions

    Directory of Open Access Journals (Sweden)

    Cartmill Linda

    2012-02-01

    Full Text Available Abstract Background Modern healthcare managers are faced with pressure to deliver effective, efficient services within the context of fixed budget constraints. Managers are required to make decisions regarding the skill mix of the workforce particularly when staffing new services. One measure used to identify numbers and mix of staff in healthcare settings is workforce ratio. The aim of this study was to identify workforce ratios in nine allied health professions and to identify whether these measures are useful for planning allied health workforce requirements. Methods A systematic literature search using relevant MeSH headings of business, medical and allied health databases and relevant grey literature for the period 2000-2008 was undertaken. Results Twelve articles were identified which described the use of workforce ratios in allied health services. Only one of these was a staffing ratio linked to clinical outcomes. The most comprehensive measures were identified in rehabilitation medicine. Conclusion The evidence for use of staffing ratios for allied health practitioners is scarce and lags behind the fields of nursing and medicine.

  20. 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 list of 434 books and 79 journals is intended as a selection guide for print literature to be used in a library supporting allied health educational programs or allied health personnel in either an academic or health care setting. Because of the impossibility of covering the large number of and wide variety of allied health professions and occupations, the recommended publications are focused primarily on the educational programs listed and recognized by the American Medical Association and other accrediting bodies. Books and journals are categorized by subject; the book list is followed by an author/editor index and the subject list of journals by an alphabetical title listing. Items suggested for initial purchase (169 books and 32 journals) are indicated by asterisks. To purchase the entire collection of books and journals (2002 subscriptions) would require an expenditure of about $36,744. The cost of only the asterisked items totals $14,465.

    Baker, Sarah S; Morrone, Anastasia S; Gable, Karen E

    2004-01-01

    Criticisms, calls for change, and recommendations for specialized accreditation improvement have been made by individuals or groups external to the daily operations of allied health educational programs, frequently as opinion pieces or articles lacking a research foundation. While there is a great deal of concern related to specialized accreditation, little input has been provided from those within, and integral to, allied health educational programs affected by specialized accreditation standards. The purpose of this study was to explore the perspectives of selected allied health deans and program directors regarding specialized accreditation effectiveness and reform. Survey research was used to study perspectives of allied health deans and program directors located in four-year colleges and universities and in academic health centers and medical schools. Surveys were mailed to program directors offering-programs in clinical laboratory sciences and medical technology, nuclear medicine technology, occupational therapy, physical therapy, radiation therapy, and radiography. Simultaneously, allied health deans located within these institutions were surveyed. A total of 773 surveys were mailed and 424 valid responses were received, yielding a response rate of 55%. The results affirmed the role of accreditation as an effective system for assuring quality in higher education. The role of specialized accreditation in improving the quality of allied health programs was clearly articulated by the respondents. Respondents voiced strong opposition to governmental or state-level requirements for accountability and emphasized the vital role of peer evaluators. Significant differences in deans' and program directors' perspectives related to specialized accreditation were evident. Whereas deans and program directors agreed with the purposes of specialized accreditation, they expressed less support for the process and effectiveness, and critique and reform, of specialized

    Dodd, Jenny; Saggers, Sherry; Wildy, Helen

    2009-01-01

    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.

    2014-11-01

    Full Text Available The issues on the diplomacy in public opinion and public consciousness is becoming increasingly important in modern domestic research on the history of Russia’s foreign policy. The article analyzes the works devoted to the social perception of Russia’s relations with allies in the Entente. The attention is paid to the historiography of the foreign political ideas of liberal and conservative leaders represented in political discourse, nonfiction works and periodicals. Liberals and conservatives were not only the object of public judgements – they formed them as well. A significant range of works deals with the problem of the relationship between the Entente allies and the Russian population. The social perception of England and France is considered by researchers both at the level of direct political, economic and military contacts, and based on an abstract image of an ally in the mass consciousness. The evolution of public perceptions of the allies was determined by the situation in the country and on the fronts and by the role of foreign stereotypes. The author analyzes the interconnection of alliance issue with the national interests of Russia, reveals research approaches to the study of the development of Patriotic and revolutionary moods, traces the differences in the estimates of England and France. The present study complements the research on diplomatic history, and yet represents a separate research problem.

    2011-01-01

    The intergranular corrosion and exfoliation corrosion of 2195 Al-Li alloy treated by multi-step heating-rate controlled aging (MSRC)are studied.The corrosion features of 2195 Al-Li alloys which are respectively treated by high-temperature nucleation MSRC(H-M)and low-temperature nucleation MSRC(L-M)are contrasted.And the corrosion mechanism of 2195 Al-Li alloy is also discussed from the viewpoint of microstructure(types,distribution,etc.)of the strengthening phase.The results show that 2195 Al-Li alloy after H-M is more susceptible to intergranular corrosion and exfoliation corrosion than that of alloy after L-M.The degree of intergranular corrosion increases with the increase of predeformation amount and the surface parallel to the rolling direction is more prone to exfoliation corrosion.The main reason of intergranular corrosion and exfoliation corrosion is the formation of corrosion galvanic couples among T1 phase,θ' phase and grain boundary precipitate-free zones(PFZ).

    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.

    Aluminum-Lithium (Al-Li) alloys offer significant performance benefits for aerospace structural applications due to their higher specific properties compared with conventional Al alloys. For example, the application of Al-Li alloy 2195 to the space shuffle external cryogenic fuel tank resulted in weight savings of over 7,000 lb, enabling successful deployment of International Space Station components. The composition and heat treatment of 2195 were optimized specifically for strength-toughness considerations for an expendable cryogenic tank. Time-dependent properties related to reliability, such as thermal stability, fatigue, and corrosion, will be of significant interest when materials are evaluated for a reusable cryotank structure. Literature surveys have indicated that there is limited thermal exposure data on Al-Li alloys. The effort reported here was designed to establish the effects of thermal exposure on the mechanical properties and microstructure of Al-Li alloys C458, L277, and 2195 in plate gages. Tensile, fracture toughness, and corrosion resistance were evaluated for both parent metal and friction stir welds (FSW) after exposure to temperatures as high as 300 F for up to 1000 hrs. Microstructural changes were evaluated with thermal exposure in order to correlate with the observed data trends. The ambient temperature parent metal data showed an increase in strength and reduction in elongation after exposure at lower temperatures. Strength reached a peak with intermediate temperature exposure followed by a decrease at highest exposure temperature. Friction stir welds of all alloys showed a drop in elongation with increased length of exposure. Understanding the effect of thermal exposure on the properties and microstructure of Al-Li alloys must be considered in defining service limiting temperatures and exposure times for a reusable cryotank structure.

    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

    De façon à compléter une étude antérieure portant sur le fluage à haute température d'un acier inoxydable austénitique du Type 316 (12-17 SPH) et afin de comprendre les relations de couplage qui existent entre les grandes déformations quasiment indépendantes du temps (plasticité) et les petites déformations souvent trés lentes (viscoplasticité), toujours intimement liées pour cet alliage, nous avons réalisé différents essais à vitesse imposée: traction, traction-compression, torsion-alternée., Durant ces essais nous avons estimé l'ordre de grandeur de la contrainte visqueuse σzz = σv par la méthode de la relaxation inverse. De façon à révéler clairement les effets liés intrinsèquement au temps avons réalisé différentes séquences de vieillissement après écrouissage. Pour intégrer et décrire l'ensemble des phénonèmes observés, nous proposons un modèle unifié dont les caractéristiques principales sont les suivantes: (i) Unicité de l'équation d'état viscoplastique: ɛ = f¦σ - α¦, avec f fortement non linéaire, ce qui permet de traduire les effets dépendant et quasiment indépendant du temps. (ii) La distinction entre grande et petite déformations s'effectue à l'aide d'un critére de charge, active ou passive, portant sur la variable α. (iii) Dans l'état de microviscoplasticé, on a α = α1, tel que α 1 présente un fort coefficient d'écrouissage h0. Dans le cas inverse, on décompose α selon α = α1 = α2 + Y et tel que les coefficients d'écrouissage vérifient: H1 + Hα2 ≪ hα1 . (iv) L'effet du temps, permettant d'atteindre l'écoulement stationnaire, indifférent à l'état du système, est pris en compte par les termes de restauration dans les lois d'évolution des variables internes. On présente quelques simulations, réalisées avec le modèle développé, pour différents types de sollicitations.

    The pitting susceptibility of 8090 Al-Li alloy in sea water, after different heat treatments, was investigated. Free corrosion and electrochemical tests were carried out at 25 C, in quiescent sea water at pH=8.2 and dissolved oxygen =6.5 ppm. The microstructure was examined by metallographic microscopy and by X-Ray microdiffractometry, while the corrosion layer was characterized by chemical methods and by Infrared and X-ray photoelectron spectroscopies. The following was observed: . aging treatments lead to a non homogeneous microstructure which increases the average corrosion rate as well as pitting susceptibility; . heat treatments do not affect the average passive film composition; . in all examined states, Al-Li alloy 8090 is subject to localized corrosion which takes place preferentially at the grain boundaries.

    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. PMID:15053221

  9. Study on Damage of High Temperature Plastic Deformation for Al-Li Alloy

    The security of use for Al-Li alloy will be greatly influenced by the damage degree of plastic deformation within it at high temperature . Based on continuum damage mechanics theory, the damage evolution of Al-5.44Mg-2.15Li-0.12Zr alloy during plastic deforming at high temperature is simulated by using the damage evolution model of high temperature plastic deformation. The changing rule of its inner damage with deformation temperature, strain rate and strain is gained in this paper. The equation of damage evolution for high temperature plastic deformation is developed, providing an academic basis for the technology of plastic process of Al-Li alloys.

    In order to develop a new high strength and high tolerance-resistance Al-Li alloy which can be used in aerospace industry,the effects of microalloying elements such as Mg, Ag, Mn and Zn on the mechanical properties of Al-Cu-Li alloys were studied. The results show that the strengthening effects of Mg+Ag and Mg+Zn additions are higher than those of the individual Mg, Ag or Zn addition. The element Mn can also bring some extent strengthening effects on the alloys, but it has nothing to do with the other microalloying elements present or not. Finally, a new Al-Li alloy with Mg+Zn+Mn additions was developed, which possesses high strength and high tolerance-resistance promising properties for aerospace applications.

    The corrosion behavior and electrochemical impedance spectroscopy ( EIS) features of 8090 Al-Li alloys in EXCO solution were investigated, and the EIS was simulated using an equivalent circuit. At the beginning of immersion in EXCO solution, the EIS is comprised by a depressed capacitive arc at high-mediate frequency and an inductive arc at low frequency, and the inductive component decreases and disappears with immersion time. Once exfoliation or severe pitting corrosion is produced, two capacitivearcs appear in the EIS. These two capacitive arcs are originated from the two parts of the corroded alloy surface, the original flat alloy surface and the new inter-face exposed to the aggressive EXCO solution due to the exfoliation or pitting corrosion.Some corrosion development features of 8090 Al-Li alloys in EXCO solution can be obtained through simulated EIS information.

    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 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 is a paradigm shift; with increase in information access, awareness about 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 To explore public health and allied career choices for AYUSH graduates with special reference to the 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.

Extended scope roles for allied health professionals is one strategy that could be undertaken by health care services to meet this demand. This review builds upon an earlier paper published in 2006 on the evidence relating to the impact extended scope roles have on health care services. Methods: A systematic review of the literature focused on extended scope roles in three allied health professional groups, ie, physiotherapy, occupational therapy, and speech pathology, was conducted. The search strategy mirrored an earlier systematic review methodology and was designed to include articles from 2005 onwards. All peer-reviewed published papers with evidence relating to effects on patients, other professionals, or the health service were included. All papers were critically appraised prior to data extraction. Results: A total of 1,000 articles were identified by the search strategy; 254 articles were screened for relevance and 21 progressed to data extraction for inclusion in the systematic review. Conclusion: Literature supporting extended scope roles exists; however, despite the earlier review calling for more robust evaluations regarding the impact on patient outcomes, cost-effectiveness, training requirements, niche identification, or sustainability, there appears to be limited research reported on the topic in the last 7 years. The evidence available suggests that extended scope practice allied health practitioners could be a cost-effective and consumer

This review and commentary summarizes relevant literature in allied fields and evaluates potential application and utility of UAS technology in the discipline of occupational hygiene. Disciplines closely related to occupational hygiene are moving to investigate potential uses--and in some cases--already employing this technology for research or commercial purposes. The literature was reviewed to formulate a cross-sectional picture of how UAS technology is being used in these closely allied disciplines which could inform or guide potential use in occupational hygiene. Discussed are UAS applications in environmental monitoring, emergency response, epidemiology, safety, and process optimization. A rapidly developing state of the art indicates that there is potential utility for this technology in occupational hygiene. Benefits may include cost savings, time savings, and averting hazardous environments via remote sensing. The occupational hygiene community can look to allied fields to garner lessons and possible applications to their own practice.

Debate exists regarding the extent to which the activities of these groups should be formalized. Results drawn from an evaluation of a large-scale peer group supervision initiative are described. Analysis of 192 responses from professionals involved in peer groups indicates that participants in groups that used formal documentation – which adopted the tools provided in training, and particularly those that used formal evaluation of their groups – rated their groups as having better processes and greater impact. Interestingly, multidisciplinary peer groups were rated as having similar impacts, processes, and purposes as the more homogenous single-discipline groups. It is concluded that the implementation of formal arrangements enhances the processes and outcomes of peer groups implemented for professional support and clinical supervision. Multidisciplinary membership of such groups is perceived as equally beneficial as single-discipline groups.

    2002-01-01

    Aluminum-Lithium (AL-Li) alloys offer significant performance benefits for aerospace structural applications due to their higher specific properties compared with conventional aluminum alloys. For example, the application of an Al-Li alloy to the space shuttle external cryogenic fuel tank contributed to the weight savings that enabled successful deployment of International Space Station components. The composition and heat treatment of this alloy were optimized specifically for strength-toughness considerations for an expendable cryogenic tank. Time dependent properties related to reliability, such as thermal stability, fatigue, and corrosion, will be of significant interest when materials are evaluated for a reusable cryotank structure. As most aerospace structural hardware is weight sensitive, a reusable cryotank will be designed to the limits of the materials mechanical properties. Therefore, this effort was designed to establish the effects of thermal exposure on the mechanical properties and microstructure of one relatively production mature alloy and two developmental alloys C458 and L277. Tensile and fracture toughness behavior was evaluated after exposure to temperatures as high as 3oooF for up to IO00 hrs. Microstructural changes were also evaluated to correlate with the observed data trends. The ambient temperature parent metal data showed an increase in strength and reduction in elongation after exposure at lower temperatures. Strength reached a peak with intermediate temperature exposure followed by a decrease at highest exposure temperature. Characterizing the effect of thermal exposure on the properties of Al-Li alloys is important to defining a service limiting temperature, exposure time, and end-of-life properties.

    The effects of magnetic field on fracture feature and microstructure of Al-Li alloys containing Ce were investigated. Experiment results show that the fracture features and the microstructures are changed with the magnetic field. The fracture surface of the alloys is mainly quasi-cleavage without applying magnetic field. With a magnetic field, the fracture of quasi-cleavage changes to more secondary cracks and less quasi-cleavage plates on fracture surface. Grains become thinner and uniform with applying magnetic field. The influence of magnetic field on atom diffusion was discussed.

    Fatigue property of Al-Li alloy after various heat treatment was investigated. The results show that the fatigue strength is enhanced with the age hardening progressing. Compared to the solution treated specimen, the fatigue limit is improved to 136% for sub-ageing treated specimen and 155% for peak-ageing treated specimen, respectively. In the meanwhile, the fatigue deformation becomes non-uniform with age hardening progressing. The fatigue cracks initiate and propagate prior from the un-uniform slip band, causing transgranular fracture or the mixed mode of transgranular fracture and intergranular fracture.

    2004-01-01

    Ordering and atom clustering in aging binary Al-Li alloy has been investigated by computer simulation through calculating the long range order (lro.) parameter and composition deviation order parameter from single-site occupation probabilities of Li atom. The results show that when the alloy lies in metastable region in the phase diagram ordering and atom clustering occur simultaneously. As the composition of the alloy increases ordering occurs earlier than atom clustering gradually. When the alloy lies in instable region atom clustering takes place after the congruent ordering completes. It has also been found that the incubation period of the phase transformation is shortened as the composition increases.

  18. On the intergranular fracture behavior of high-temperature plastic deformation of 1420 Al-Li alloy

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The tensile deformation hot simulation test of as-cast 1420 Al-Li alloy was performed on Gleeble-1500 Thermal Simulator in the deformation temperature range from 350 to 450 ℃, and the strain rate range from 0.01 to 10.0 s-1.The tensile fracture behavior of the 1420 Al-Li alloy at high temperature was studied experimently. The results show that the tensile fracture mode of the 1420 Al-Li alloy at high temperature is changed from typical transgranular ductile fracture to intergranular brittle fracture with the increase of the deformation temperature and the strain rate. It is made out that the precipitation of LiH is the fundamental reason for the intergranular brittle fracture of the 1420 Al-Li alloy at high temperature. The mechanism of hydrogen embrittlement of the 1420 Al-Li alloy at high temperature was discussed, and it was proposed that the hydrogen embrittlement at high temperature is an integrated function of the dynamic and the static force, which enrichs the theories of hydrogen embrittlement.

    Ferns and fern allies have low photosynthetic rates compared with seed plants. Their photosynthesis is thought to be limited principally by physical CO2 diffusion from the atmosphere to chloroplasts. The aim of this study was to understand the reasons for low photosynthesis in species of ferns and fern allies (Lycopodiopsida and Polypodiopsida). We performed a comprehensive assessment of the foliar gas-exchange and mesophyll structural traits involved in photosynthetic function for 35 species of ferns and fern allies. Additionally, the leaf economics spectrum (the interrelationships between photosynthetic capacity and leaf/frond traits such as leaf dry mass per unit area or nitrogen content) was tested. Low mesophyll conductance to CO2 was the main cause for low photosynthesis in ferns and fern allies, which, in turn, was associated with thick cell walls and reduced chloroplast distribution towards intercellular mesophyll air spaces. Generally, the leaf economics spectrum in ferns follows a trend similar to that in seed plants. Nevertheless, ferns and allies had less nitrogen per unit DW than seed plants (i.e. the same slope but a different intercept) and lower photosynthesis rates per leaf mass area and per unit of nitrogen.

    Une nouvelle interprétation du comportement atypique couramment appelé "breakaway" observé lors de l'oxydation à haute température d'alliages chromino-formeurs est proposée grâce à l'utilisation de la diffraction des rayons X in situ à haute température. L'acier chromino-formeur AISI 304 doit établir une couche d'oxyde superficielle généralement dense et majoritairement, constituée de chromine, dont la vitesse de croissance est lente, afin d'assurer sa protection contre la corrosion à haute température. Cette faible vitesse de croissance de la couche d'oxyde est effectivement observée à 1000circC. Elle serait favorisée par l'établissement d'une couche de chromine induite par la présence d'une sous-couche continue de silice à l'interface interne. Cette dernière limiterait la diffusion du fer. Le phénomène du "breakaway" est observé à la température de 900circC après 40 heures d'oxydation. Ce phénomène serait lié à la croissance initiale d'oxydes contenant du fer. L'oxyde Fe{7}SiO{10, }a été identifié{ }pour la première fois grâce à la technique de diffraction des rayons X in situ à haute température. Cet oxyde semble piéger le silicium dans la couche d'oxyde, empêchant son accumulation à l'interface interne et la formation d'une couche continue de silice.

    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.

    Full Text Available Abstract Background 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. Methods 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. Results 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.

    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)

    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.

    Full Text Available Al-Li alloy and aluminum honeycomb panel (AHP are both excellent materials for aeronautical structures. In this paper, a plate-type aeronautical structure (PAS, which is a base mounting structure for 172 kg functional devices, is selected for comparative analysis with different materials. To compare system-level performance under multidisciplinary constraints, mathematical models for optimization are established and then structural optimization is carried out using Altair OptiStruct. For AHP, its honeycomb core is regarded as orthotropic material and its mechanical properties are calculated by Allen’s model in order to establish finite element model (FEM. The heights of facing sheet and honeycomb core are selected as design variables for size optimization. For Al-Li alloy plate, topology optimization is carried out to obtain its most efficient load path; and then a reconstruction process is executed for practical manufacturing consideration; to obtain its final configuration, accurate size optimization is also used for reconstructed model of Al-Li alloy plate. Finally, the optimized mass and performance of two PASs are compared. Results show that AHP is slightly superior to Al-Li alloy.

    The purpose of the present study was to investigate the levels of either the nutraceutical and health-promoting compounds or the antioxidant properties of innovative eggplant (Solanum melongena L.) genotypes tolerant and/or resistant to fungi, derived from conventional and non-conventional breeding methodologies (i.e., sexual interspecific hybridization, interspecific protoplast electrofusion, androgenesis, and backcross cycles) in comparison with their allied and cultivated parents. Chemical measures of soluble refractometric residue (SRR), glycoalkaloids (solamargine and solasonine), chlorogenic acid (CA), delphinidin 3-rutinoside (D3R), total phenols (TP), polyphenoloxidase (PPO) activity, antiradical activity on superoxide anion and hydroxyl radical were carried out in raw fruit and peel of 57 eggplant advanced introgression lines (ILs), of three eggplant recurrent genotypes and of three allied species during 2005 and 2006. The majority of the ILs, obtained after several backcross cycles, showed positive characteristics with respect to the allied parents such as good levels of SRR, CA, D3R, TP, PPO activity, the scavenging activity against superoxide anion and hydroxyl radical and, in particular, significantly (p allied parents (i.e., resistance/tolerance to plant pathogen fungi) together with nutraceutical and antioxidant properties typical of the cultivated species.

    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. PMID:23069367

    Full Text Available The purpose of this study was to assess the mechanism of corporate meetings under the Companies and Allied Matters Act (CAMA 1990. This review revealed two major types of meetings, public meetings convened by individuals or bodies to which there is an open invitation extended to any member of the public, and meetings of bodies of which the members are limited and known. However, the study was preoccupied with the second category. Therefore, there is the need for the various Legislatures of countries to work towards enacting effective and efficient company legislation to that effect. It is recommended among others that in Nigeria that the fine of N50 for every day of default to hold a statutory meeting should be reviewed to be punitive.

    The Health-e-Learning project investigated the use of videoconferencing to deliver interprofessional clinical education to allied health students. Via a broadband link, students observed DVD footage of a clinical session then participated in discussion with the clinicians at the Royal Children's Hospital (RCH), Melbourne. The videoconference sessions were evaluated with respect to session content, the effectiveness of videoconferencing in providing interprofessional education (IPE) and the satisfaction with this as a supplement to facility-based placements. During the two semesters of the project, 28 videoconference sessions were conducted and 724 participants were surveyed. Student responses were positive with 84% indicating that these videoconferences increased their understanding of interprofessional practice (IPP) and 95% agreeing that the sessions were an effective learning tool. The results of this study support the use of videoconferencing to provide interprofessional clinical education. PMID:22458640

    2006-01-01

    The effect of two-stage aging on the microstructures and superplasticity of 01420 Al-Li alloy was investigated by means of OM, TEM analysis and stretching experiment. The results demonstrate that the second phase particles distributed more uniformly with a larger volume fraction can be observed after the two-stage aging (120 ℃, 12 h+300 ℃, 36 h) compared with the single-aging(300 ℃, 48 h). After rolling and recrystallization annealing, fine grains with size of 8-10 μm are obtained, and the superplastic elongation of the specimens reaches 560% at strain rate of 8×10-4 s-1 and 480 ℃. Uniformly distributed fine particles precipitate both on grain boundaries and in grains at lower temperature. When the sheet is aged at high temperature, the particles become coarser with a large volume fraction.

  6. Strength and microstructure of 2091 Al-Li alloy TIG welded joint

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The microstructure and tensile properties of TIG welding joints of 2091 Al-Li alloy were investigated both in as-welded and different postweld heat treatment condition. The results show that solution strengthening played an important role in the as-welded condition, though the precipitation strengthening δ' phase formed already in the as-welded weld metal, but its effect was not apparent due to the lower volume fraction of δ' phase. So the strength coefficient (φ) of the welded joint/base metal was 64%. After artificially aging heat treatment, the precipitation strengthening effect increased much due to the formation of more δ' phase and s' phase. Its φ value was increased up to 89%. The highest strength of the welded joints was obtained after solid solution and then artificially aged heat treatment. Due to the proper size of precipitation strengthening phases and their well distribution, the φ value was increased up to 98%.

  7. Effect of current pulses on fracture morphology in superplastic deformation of 2091 Al-Li alloy

    Institute of Scientific and Technical Information of China (English)

    1999-01-01

    The effect of current pulses on the fracture morphology in the superplastic deformation of 2091 AlLi alloy at two kinds of initial strain rate ((ε)1 = 3.33 × 10 -3 s-1;(ε)2= 3.33 × 10-2 s- 1 ) was investigated. Experimental results show that current pulse turns fracture of superplastic deformation at low strain rate from local interior fracture morphology to typical fracture by growth and interlinkage of cavities, and at high strain rate from rough grain boundary surface to smooth grain boundary surface. It is indicated that the characteristic, that current pulse promotes atomic diffusion, maintains an equiaxial grain microstructure at low strain rate, and accelerates the development of diffusional type of cavity and relaxes stress concentration at triple junction of grain boundaries at high strain rate, and makes the superplastic deformation at two kinds of strain rate show a normal superplastic fracture morphology.

    The Medical College of Georgia's (MCG's) Minority Academic Advising Program (MAAP), which began in 1984, is a supplementary retention program for Black students. This paper describes an evaluation study of the effectiveness of MAAP within the MCG School of Allied Health Sciences (SAHS). The study sample consisted of 89 Black students who enrolled in the SAHS from fall 1978 to fall 1982 (preMAAP period) plus 129 Black students who entered the SAHS from fall 1984 through fall 1988 (MAAP period). The comparison group consisted of all other students who entered the SAHS (n = 1,884) within those same time periods. Using an evaluation design produced by merging a quasi-experimental and a time-series design, the authors found that the MAAP succeeded in increasing both the Black student retention-to-graduation rate and the time-persisted-in-program, to the extent that Black students achieved parity with other SAHS students.

    The exfoliation morphologies and electrochemical impedance spectroscopy (EIS) features of as-received rolled AA8090 Al-Li alloy in EXCO solution were studied. The EIS was simulated using an equivalent circuit. The results show that once the exfoliation occurs, the EIS is composed of two capacitive arcs at high frequency and mediate-low frequency; among them, the capacitance corresponding to high frequency (C1) is originated from original flat alloy surface, while the capacitance corresponding to mediate-low frequency (C2) from new interface exposed to EXCO solution due to the exfoliation and the ratio of C2 to C1 increases with exfoliation degree. It is advanced that the exfoliation degree can be quantitatively judged through this ratio.

    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 Background: The last comprehensive list of lichenised, lichenicolous and allied fungi reported from South Africa was published in 1950. A checklist is important to provide basic information on the extent of the diversity, and to provide the most recent name and classification.Objective: To present a list of all the lichenised, lichenicolous and allied fungi reported from South Africa.Methods: The list presented is entirely literature based and no attempt has been made to check the report of any taxa or their status by checking the specimens upon which they are based. Firstly, all taxa that were not reported from within the modern boundaries of South Africa were excluded. Next, the Recent literature on lichens database was searched for literature on South African lichens since 1945 and all references checked for new species or new reports, which were then added to the list. These names were then checked against Index Fungorum to ensure that the most current name was being used. Finally, the list was rationalised by excluding all synonyms and dubious infraspecific taxa.Results: The current list includes 1750 taxa in 260 genera from mainland South Africa, with an additional 100 species and 23 genera from the sub-Antarctic Prince Edward Islands, which are treated separately. The replacement name Verrucaria dagolavii Fryday is proposed for Verrucaria umbilicata Øvstedal.Conclusion: It is estimated that, when fully explored, the lichen biota of South Africa will consist of somewhere between 2500 and 3000 taxa.

    2010-01-01

    This study was designed to investigate leadership behaviors among chairpersons in allied health programs, based on their perceptions and the perceptions of faculty. Transformational, transactional, and laissez-faire leadership behaviors, as well as organizational outcomes of effectiveness, extra effort, and satisfaction, were measured using the Multifactor Leadership Questionnaire (MLQ Form 5X-Short). A form developed by the researcher was used to gather demographic and program information. One hundred thirty-eight chairpersons and 327 faculty participated in the study. Major findings support the view that chairpersons primarily demonstrate leadership behaviors associated with transformational leadership factors and the contingent reward factor of transactional leadership. Statistically significant differences were found between the mean values of the self-perceptions of chairpersons and faculty for the transformational leadership factors of idealized influence (behavior), inspirational motivation, intellectual stimulation, individual consideration, and organizational outcomes of effectiveness and satisfaction. There was a statistically significant positive correlation, based on the self-perceptions of chairpersons and faculty, of the five transformational leadership factors with the three organizational outcomes and the transactional leadership factor of contingent reward with the organizational outcomes of effectiveness and extra effort. There was a statistically significant negative correlation, based on the perception of faculty, with the management-by-exception (passive) and laissez-faire leadership factors, and the organizational outcomes of effectiveness, extra effort and satisfaction. Transformational leadership has been identified as an effective strategy to adapt to a rapidly changing environment. Further development of the transformational leadership behaviors of chairpersons should be considered a priority for the allied health professions. PMID

    Full Text Available BACKGROUND: The focus of this study was to investigate factors that may influence personal willingness to register consent to donate corneal tissue upon death using the theory of planned behaviour in a relatively ethnically homogenous group of trainee allied health professionals. The attainment of this knowledge will be of paramount importance in relation to potential interventions that are designed to change donation-related behaviour. METHODS: A questionnaire-based study was undertaken with 92 pre-registration nurses (mean age 24.0 years (standard deviation ± 5.6 years; female:male = 89:3 enrolled at a University in Northern Ireland. Intention to register consent to donate corneal tissue upon death was assessed using both direct and belief-based measures found in the theory of planned behaviour. Descriptive statistics were used to assess demographic information, with correlation and regression analyses being used to identify factors influencing intentions. RESULTS: The majority of participants were religious (94.6%, n = 87 and mostly Protestant (58.7%, n = 54 or Catholic (35.9%, n = 33. Generally speaking, the theory of planned behaviour accounted for 84% of the variance in intention to register consent. In relation to the constructs found in the theory of planned behaviour, attitude was found to be the strongest predictor of intention to register consent, with subjective norm being the second strongest predictor. Perceived behavioural control did not significantly predict intention to register consent. CONCLUSIONS: The theory of planned behaviour has allowed an understanding of the factors that influence the personal intentions of a group of future allied health professionals from the same ethnic group to register consent to donate their corneal tissue.

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

    Directory of Open Access Journals (Sweden)

    Ezequiel Reficco

    1998-09-01

    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.

  16. Effects of Annealing Process on the Formability of Friction Stir Welded Al-Li Alloy 2195 Plates

    Chen, Po-Shou; Bradford, Vann; Russell, Carolyn

    2011-01-01

    Large rocket cryogenic tank domes have typically been fabricated using Al-Cu based alloys like Al-Cu alloy 2219. The use of aluminum-lithium based alloys for rocket fuel tank domes can reduce weight because aluminum-lithium alloys have lower density and higher strength than Al-Cu alloy 2219. However, Al-Li alloys have rarely been used to fabricate rocket fuel tank domes because of the inherent low formability characteristic that make them susceptible to cracking during the forming operations. The ability to form metal by stretch forming or spin forming without excessive thinning or necking depends on the strain hardening exponent "n". The stain hardening exponent is a measure of how rapidly a metal becomes stronger and harder. A high strain hardening exponent is beneficial to a material's ability to uniformly distribute the imposed strain. Marshall Space Flight Center has developed a novel annealing process that can achieve a work hardening exponent on the order of 0.27 to 0.29, which is approximately 50% higher than what is typically obtained for Al-Li alloys using the conventional method. The strain hardening exponent of the Al-Li alloy plates or blanks heat treated using the conventional method is typically on the order of 0.17 to 0.19. The effects of this novel annealing process on the formability of friction stir welded Al-Li alloy blanks are being studied at Marshall Space Flight Center. The formability ratings will be generated using the strain hardening exponent, strain rate sensitivity and forming range. The effects of forming temperature on the formability will also be studied. The objective of this work is to study the deformation behavior of the friction stir welded Al-Li alloy 2195 blank and determine the formability enhancement by the new annealing process.

    Full Text Available Background: Scientific research into mental health outcomes following trauma is undergoing a revolution as scientists refocus their efforts to identify underlying dimensions of health and psychopathology. This effort is in stark contrast to the previous focus which was to characterize individuals based on Diagnostic and Statistical Manual of Mental Disorders (DSM diagnostic status (Insel et al., 2010. A significant unresolved issue underlying this shift is how to characterize clinically relevant populations without reliance on the categorical definitions provided by the DSM. Classifying individuals based on their pattern of stress adaptation over time holds significant promise for capturing inherent inter-individual heterogeneity as responses including chronicity, recovery, delayed onset, and resilience can only be determined longitudinally (Galatzer-Levy & Bryant, 2013 and then characterizing these patterns for future research (Depaoli, Van de Schoot, Van Loey, & Sijbrandij, 2015. Such an approach allows for the identification of phenominologically similar patterns of response to diverse extreme environmental stressors (Bonanno, Kennedy, Galatzer-Levy, Lude, & Elfstom, 2012; Galatzer-Levy & Bonanno, 2012; Galatzer-Levy, Brown, et al., 2013; Galatzer-Levy, Burton, & Bonanno, 2012 including translational animal models of stress adaptation (Galatzer-Levy, Bonanno, Bush, & LeDoux, 2013; Galatzer-Levy, Moscarello, et al., 2014.

    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 fanning 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,prpe-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 industries in the state.

    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

    The effect of electric field on the mechanical properties and microstructure of Al-Li alloy containing Ce was investigated, and mechanism was discussed. The experimental results show that the ductility of the alloy is enhanced by the electric field. The fracture features are changed and the precipitates are dispersed under the effect of the electric field. The mechanism discussion reveals that the effects of the electric field on the alloy are due to the change of the electron density in the alloy.

    Full Text Available Background. Evidence indicates that Stroke Units decrease mortality and morbidity. An Acute Stroke Unit (ASU provides specialised, hyperacute care and thrombolysis. John Hunter Hospital, Australia, admits 500 stroke patients each year and has a 4-bed ASU. Aims. This study investigated hospital admissions over a 5-year period of all strokes patients and of all patients admitted to the 4-bed ASU and the involvement of allied health professionals. Methods. The study retrospectively audited 5-year data from all stroke patients admitted to John Hunter Hospital (n=2525 and from nonstroke patients admitted to the ASU (n=826. The study’s primary outcomes were admission rates, length of stay (days, and allied health involvement. Results. Over 5 years, 47% of stroke patients were admitted to the ASU. More male stroke patients were admitted to the ASU (chi2=5.81; P=0.016. There was a trend over time towards parity between the number of stroke and nonstroke patients admitted to the ASU. When compared to those admitted elsewhere, ASU stroke patients had a longer length of stay (z=−8.233; P=0.0000 and were more likely to receive allied healthcare. Conclusion. This is the first study to report 5 years of ASU admissions. Acute Stroke Units may benefit from a review of the healthcare provided to all stroke patients. The trends over time with respect to the utilisation of the John Hunter Hospitall’s ASU have resulted in a review of the hospitall’s Stroke Unit and allied healthcare.

    Leadership behaviors are an important aspect of athletic training and are needed within all allied health care disciples. A two-phase, exploratory, non-experimental research study using a Delphi technique and a randomly selected sample of athletic trainers (n = 161) was conducted to determine leadership competencies perceived to be important for athletic training practice and education. The Delphi technique (phase one) resulted in the Leadership Development in Athletic Training instrument (LDAT). In the national survey (phase two), respondents used the LDAT to rate the importance of leadership competencies for athletic training practice and for athletic training education. Coefficient alphas ranged from α = 0.83 to 0.97 and provided satisfactory estimates of internal consistency. Concurrent, construct, and convergent validity were established. Forty-nine leadership competencies were rated important for practice and 48 for education (M = 1.5, p ≤ 0.001). Exploratory factor analysis revealed that leadership competencies were organized by four constructs (with six emphases): 1) personality characteristics, 2) diagnosing context and people skills, 3) communication and initiative, and 4) strategic thinking. Repeated measures ANOVA with Sidak post-hoc adjustments indicated each leadership construct significantly increased in importance as the level of the ATEP progressed. PMID:21184023

    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. PMID:24049449

    The treatment and care of patients with rheumatoid arthritis (RA) is complex and various health professionals with different areas of expertise may be involved. The objective of this article is to review the treatments and their efficacy as provided by health care professionals in RA care. The requirements for further research in this area are formulated. To achieve better effects of treatment it is necessary to improve the coordination of services as provided by the different specialists. The important roles of the patients themselves in the care and management of the disease are emphasized, as well as the roles of the informal caregivers such as a spouse or other family members and friends and the role of patient societies. The possible role of the International Classification of Functioning, Disability and Health (ICF) to improve the communication and facilitate the coordination among health professionals and between patients and health professionals is mentioned. The topics presented in this article may encourage further discussion and research, particularly concerning the effects of the treatments as provided by allied health professionals. Health professionals play an important role in the life of patients with rheumatic disorders, in all the domains of the ICF: body functions and structure, activities (action by an individual) and participation (involvement in a life situation). Health professionals in rheumatology can make the difference in the lives of RA patients and their families.

    Full Text Available Crocus sativus L. is mainly known for the production of the drug saffron. Because of its sterility, it is propagated vegetatively by means of corms. To gain information on the reproductive biology of saffron and allied species, a comparative study on pollen and pistil of Crocus sativus L., C. cartwrightianus Herb., C. thomasii Ten. and C. hadriaticus Herb. was carried out. Pollen and pistils gathered at anthesis were examined by light (LM and scanning electron microscopy (SEM. Pollen shape and size, anomalous pollen grain percentage, pollen viability, pollen germination in vitro and on self-, and cross-pollinated stigmas were examined. Pistils at different developmental stages were examined by light microscopy. C. hadriaticus had the smallest pollen; C. sativus showed a higher percentage of anomalous and aborted grains and a lower percentage of viable grains. Pollen germination in vitro as well as on differently pollinated stigmas was lowest in C. sativus. Pistil organization was similar in all the species, but ovule number and integuments varied. Embryo sacs mature early, and female gametophyte development is regular for some days after flower anthesis. Capsules with seeds were obtained from all diploid species as well as in saffron after free- and cross-pollination. Results confirm that sterility in C. sativus is mainly confined to pollen.

  16. Law and Justice on TV. The Wire vs. CSI and Ally McBeal

    Full Text Available The aim of this paper is to analyse the ways in which law is represented in the celebrated TV series The Wire, broadcasted in United States between 2002 and 2008. The analysis focuses particularly on the thematization of the relationship between the concept of law and that of justice, that is between 'positive law' and 'natural law'. This theme is pursued in the context of American television series of great success such as CSI: Crime Scene Investigation (CBS, 2000- and Ally McBeal (Fox, 1997-2002 . The comparison highlights the way in which in The Wire the terms of the problem are completely eroded through the representation of a sort of 'disappearance of justice'. In this series the natural law becomes insignificant both because it is no more the point of reference of the actions activated by the institutions, and because an informed, in-depth and not prejudicial gaze on the social reality of the contemporary metropolis brings into question the very idea of a justice absolute and distanced from the contingent circumstances.

    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.

    Delamination fracture has limited the use of lightweight Al-Li alloys. Studies of secondary, delamination cracks in alloy 2090, L-T fracture toughness samples showed grain boundary failure between variants of the brass texture component. Although the adjacent texture variants, designated B(sub s1) and B(sub s2), behave similarly during rolling, their plastic responses to mechanical tests can be quite different. EBSD data from through-thickness scans were used to generate Taylor factor maps. When a combined boundary normal and shear tensor was used in the calculation, the delaminating grains showed the greatest Taylor Factor differences of any grain pairs. Kernel Average Misorientation (KAM) maps also showed damage accumulation on one side of the interface. Both of these are consistent with poor slip accommodation from a crystallographically softer grain to a harder one. Transmission electron microscopy was used to confirm the EBSD observations and to show the role of slip bands in the development of large, interfacial stress concentrations. A viewgraph presentation accompanies the provided abstract.

    Al-Li alloy 2195 is a low-density material with high fracture toughness that is particularly well-suited for aerospace systems. It will replace Al-Cu alloy 2219 in the Super Light Weight Tank (SLWT), a modified version of the external tank being developed for the Space Shuttle to support Space Station deployment. Recent efforts have focused on joining 2195 with variable polarity plasma arc welding, as well as repairing 2195 welds with tungsten inert gas techniques. During this study, Auger electron spectroscopy (AES) was used to examine grain boundary chemistry in 2195 welds. Results indicated that weld integrity depends on whether (and how much) the grain boundaries are covered with thin films comprised of a mixture of discontinuous Al{sub 2}O{sub 3} in Al (Al/Al{sub 2}O{sub 3}), which form during weld solidification. O was probably introduced as a contaminant in the shielding gases, occurring at low levels considered negligible for Al alloys that do not contain Li. However, oxidation kinetics in 2195 are increased by Li enrichment of small quantities of Al{sub 2}O{sub 3}, further enhancing thin film formation at the grain boundaries. Al{sub 2}O{sub 3} can ultimately occupy sufficient grain boundary area to degrade the material`s mechanical properties, producing negative effects that are compounded by the cumulative heat input of multi-pass repair welding.

    The evolution of the grain structures in AA2195 Al-Li alloy plate warm-rolled by 80% reduction during recrystallization annealing at 500 ℃ was investigated by electron backscatter diffraction, scanning electron microscopy and transmission electron microscopy. It is found that the elongated grain structures are caused by the lamellar distribution of recrystallization nucleation sites,being lack of large second phase particles (> 1 μm), and dispersive coherent particles (such as δ'andβ) concentrated in planar bands.The recrystallization process may be separated into three stages: firstly, recrystallization nucleation occurs heterogeneously, and the nuclei are concentrated in some planar zones parallel to rolling plane. Secondly, the grain boundaries interacted with small particles concentrate in planar bands, which is able to result in the elongated grain structures. The rate of the grain growth is controlled by the dissolution of these small particles. Thirdly, after most of small particles are dissolved, their hindrance to migration of the grain boundaries fades away, and the unrecrystallized zones are consumed by adjacent recrystallized grains. The migration of high angle grain boundaries along normal direction leads a gradual transformation from the elongated grains to the nearly equiaxed, which is driven by the tension of the grain boundaries.

    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.

    In 1975 and 1976, 8 teams of investigators located 262 colonies of nesting herons and their allies along the Atlantic coast from Florida to Maine [USA]. Fourteen species [Ajaia ajaja, Plegadis falcinellus, Nycticorax nycticorax, Ardea herodias, Eudocimus albus, Egretta thula, Hydranassa tricolor, Bubulcus ibis, Casmerodius albus, Butorides striatus, Florida caerulea, Dichromanassa rufescens, Nyctanassa violacea and Mycteria americana] were found in Florida, numbers decreasing to 7 in Maine. Colonies censused in the extreme south and north of the study area were lower in number of species and number of adults than those in the intermediate area. More than 90% of the colony sites surveyed in 1975 were active in 1976. The total number of nesting adults per colony, number of species per colony and number of nesting adults of each species per colony in 1976 were significantly correlated with their respective values for 1975. Abandoned and new colonies may be satellites of nearby reused colonies; they had fewer individuals and species than reused colonies and were closer to reused colonies than reused colonies were to each other. [This study was part of an attempt to examine colonially nesting herons as biological indicators of environmental quality.

  4. Did the Allies Know in 1942 About Nazi Germany's Poor Prospects for an Atomic Bomb?

    According to official accounts, the U.S. knew nothing about Nazi Germany's efforts to get an atomic bomb until the end of the World War II, but had feared the worst. As it turned out, the Germans had made little progress. But did someone in the Allied camp know in 1942? In his 1986 book, The Griffin, Arnold Kramish relates how Paul Rosbaud, a spy for MI6, the British secret intelligence service, kept his handlers informed during the War about the German atomic project and reported the decision to give up on a bomb. Kramish's revelations are, understandably, thinly documented and Rosbaud's name can hardly be found independenly anywhere else. But as Samuel Goudsmit's papers in the Bohr Library show, he knew and communicated with Rosbaud from August 1945 on. In 1986, 15 letters exchanged by Goudsmit and Rosbaud were removed by the Government from the Library and eventually placed in the National Archives under classification review. Renewed interest in the Rosbaud story was engendered last year when his family sued MI6 in an English court for the release of the Rosbaud file. So far the spy agency has refused to reveal even that there is such a file. Discovering authoritatively what Rosbaud told the British and what they did with the information is clearly of historical interest.

    Full Text Available Dengue is the most common arboviral disease of humans. There is an unmet need for a therapeutic intervention that reduces the duration and severity of dengue symptoms and diminishes the likelihood of severe complications. To this end, there are active discovery efforts in industry and academia to develop interventions, with a focus on small molecule inhibitors of dengue virus replication that are suitable for therapy or chemoprophylaxis. Advancements in animal models of dengue virus infection together with the possibility of a dengue human infection model have further enhanced the platform for dengue drug discovery. Whilst drug discovery efforts gestate, there are ongoing clinical research designed to benefit today's patients, including trials of supportive care interventions, and descriptive studies that should improve the ability of clinicians to make an accurate diagnosis early in the illness course and to identify patients most at risk of progression to severe disease. This review provides a state of the art summary of dengue drug discovery, clinical trials, and supportive allied research and reflects discussions at the 2nd International Dengue Therapeutics Workshop held in Ho Chi Minh City, Vietnam, in December 2013.

    2004-01-01

    The exfoliation corrosion susceptibility and electrochemical impedance spectroscopy(EIS) of rolled and peak-aged 8090 Al-Li alloys in EXCO solution were studied, and the EIS after exfoliation was simulated. Once exfoliation occurs, two capacitive arcs appear in the EIS at high-mediate frequency and mediate-low frequency respective ly. The exfoliation-attacked alloy surface consists of two parts, an original flat alloy surface and a new inter-face exposed to EXCO solution due to the exfoliation. The capacitance corresponding to the new exfoliation inter-face in creases approximately linearly with time at early exfoliation stage, due to the enlargement of the new inter-face. Then it maintains stable, due to the corrosion product covering on the new inter-face. The exfoliation susceptibility can be judged through the average slope of the capacitance vs time curve of the early exfoliation stage. This average slope of the rolled 8090 alloy is much higher than that of the peak-aged 8090 alloy, accordingly the rolled 8090 alloy is more susceptible to exfoliation than the peak-aged 8090 alloy.

    Laser welding of advanced Al-Li alloys has been developed to meet the increasing demand for light-weight and high-strength aerospace structures. However, welding of high-strength Al-Li alloys can be problematic due to the tendency for hot cracking. Finding suitable welding parameters and filler material for this combination currently requires extensive and costly trial and error experimentation. The present work describes a novel coupled model to predict hot crack susceptibility (HCS) in Al-Li welds. Such a model can be used to shortcut the weld development process. The coupled model combines finite element process simulation with a two-level HCS model. The finite element process model predicts thermal field data for the subsequent HCS hot cracking prediction. The model can be used to predict the influences of filler wire composition and welding parameters on HCS. The modeling results have been validated by comparing predictions with results from fully instrumented laser welds performed under a range of process parameters and analyzed using high-resolution X-ray tomography to identify weld defects. It is shown that the model is capable of accurately predicting the thermal field around the weld and the trend of HCS as a function of process parameters.

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

  9. Application of nuclear and allied techniques for the characterization of forensic samples

    International Nuclear Information System (INIS)

    Forensic science deals with the application of various techniques - physical, chemical, and biological - for crime investigation. The legal implications of such analyses put considerable restrictions on the choice of techniques. Moreover, the unknown nature of materials, the limited availability of samples, and the large number of elements to be analysed put considerable strain on the analyst to select appropriate methods.The availability of nuclear techniques has considerably enhanced the scope of forensic analysis. Multi-technique approaches, involving nuclear and non-nuclear analytical methods, have proven to be valid and versatile. In this paper we present recent results from the use of nuclear and allied analytical methods for forensic applications. Some of the forensic samples recently analysed in our laboratories will also be discussed. One of the major types of samples handled pertains to the identification of gunshot residues, and nuclear techniques have considerably simplified interpretation of results. Analysis of unknown materials like powders or metallic fragments for the possible presence of illicit nuclear material is becoming more essential. Characterization of materials is also of importance in view of the possible dumping of toxic wastes from developed countries in developing countries. Detection of gold in a smuggling case was possible using X ray fluorescence and neutron activation analysis even though the smuggler used an innovative approach and converted the gold to a colourless cyanide complex to prevent its easy detection. Analysis of commercial pharmaceutical or medicinal preparations for toxic metals is also becoming important in view of the illegal use of materials like heroin. The increasing volume of illegal and criminal activities requires judicious application of nuclear and non-nuclear techniques for the conviction of criminals and, more importantly, for acquittal of the innocent.

    In 2003, the U.S. Department of Education's National Center for Education Statistics conducted the National Assessment of Adult Literacy (NAAL). The NAAL reported that over 90 million adults were functionally or marginally illiterate. When these individuals encounter the health care system, they often have difficulties with reading and understanding basic text and, as a result, have difficulty managing their disease or using medications. The purpose of this article is to describe our initial efforts to educate our students concerning health literacy, its consequences, and our assessment. As part of a new segment of the allied health curriculum, second-year dental hygiene students received a lecture concerning the prevalence of poor literacy in America and the possible consequences of poor literacy on their patients' ability to maintain oral health. To provide clinical experience with assessing health literacy, the students were instructed in the administration of a validated medical health literacy tool. This clinical exercise had two functions: 1) to familiarize students with assessing health literacy as part of their clinical experience and 2) to continue to gather preliminary data concerning the level of health literacy of adult patients at Indiana University School of Dentistry using a standardized methodology, the Short Test of Functional Health Literacy in Adults (S-TOFHLA). The results indicated that 13 percent of those assessed had "inadequate" or "marginal" literacy as measured by the S-TOFHLA. As a result, we plan to continue to expand our educational efforts and develop a larger investigation of the prevalence in our dental school population. With these data, we hope to develop effective educational programs and experiences for our students, faculty, and staff to improve their awareness and communication skills and ultimately improve the oral health of our patients.

    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.

    There have been numerous changes in the health care system, including cost-containment efforts, the increased growth of managed care, and shortages of many health professionals. It is important to assess the impact these changes are having on the quality of health care delivery and the way various health professionals view their jobs. To accomplish this assessment, a sample of experienced nursing and allied health professionals were asked to provide their assessment of positive and negative changes in the health system over a 5-year period. They also were asked to indicate their level of satisfaction with their profession, their current job, and various aspects of that job. A Health Care Environment Survey was mailed to six groups of graduates of a mid-Atlantic college of health professions. Three of the groups had been in practice for 5 years, and three of the groups had been in practice for 10 years. The survey asked respondents to assess the magnitude of certain changes in the health system over the previous 5 years and to provide an assessment of their satisfaction with their current job. A total of 1,610 surveys were mailed, and 787 were returned for a rate of 49%. Nursing and allied health professionals who responded to the survey reported that there have been many more negative than positive changes in the health care system, including less job security, efficiency, and time available to spend with individual patients and increases in workload, paperwork, and control of health care by insurance companies. Even with these negative changes, nurses and allied health professionals report a high level of satisfaction with their jobs. In investigating the aspects of their jobs that were most related to satisfaction, having a feeling of worthwhile accomplishment from their job, opportunities for personal and professional growth, recognition and satisfaction with their workload were found to be the best predictors of job satisfaction.

    Full Text Available Lucylynn Lizarondo, Karen Grimmer, Saravana KumarInternational Center for Allied Health Evidence, University of South Australia, Adelaide, SA, AustraliaPurpose: A recent trial which examined the impact of a structured model of journal club (JC demonstrated variability in evidence-based practice (EBP outcomes across allied health disciplines. The aim of the current study was to determine if there are individual practitioner characteristics that could explain this variability and identify potential predictors of EBP outcomes.Method: This exploratory study used the data obtained from the JC trial. The predictive value of practitioner-related variables including academic degree, previous exposure to EBP training, and previous research involvement was analyzed using univariate logistic regression models. The dose of intervention was also included in the exploratory analysis.Results: The change in self-reported knowledge, evidence uptake, and attitude following participation in a JC was influenced by individual practitioner characteristics including their discipline, academic background, previous EBP training, previous research involvement, and JC attendance. Improvement in objective knowledge did not seem to be affected by any of these variables. Whether these individual characteristics have the ability to predict who will achieve less than, or greater than, 50% change in knowledge, attitude, and evidence uptake, is not known, except for academic background which predicted physiotherapists' improvement in attitude.Conclusion: Participation in a structured JC can lead to significant improvements in EBP knowledge irrespective of the characteristics of individual practitioners. The change in attitude and evidence uptake, however, may be influenced by individual characteristics which will therefore require careful consideration when designing EBP interventions. An EBP intervention is likely to be successful if a systematic assessment of the barriers at

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

    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

    Full Text Available Nursing and allied health care students use online learning resources with their own perspective of learning, often combined with curiosity. Although, students are overwhelmed with access to an enormous pool of information, we hypothesized that students may not possess the skills to appraise the merits of all online resources. Our pilot survey results have shown that students’ knowledge of literature appraisal is inadequate. Circumventing this barrier requires adopting a three-phase protocol for literature triage such as: selection, appraisal, and critical reading. These skills would facilitate assessing all aspects of the literature, and identifying the best learning material.

    The corrosion behaviors of 1420 and 2195 Al-Li alloys under 308 and 490 MPa tensile stress respectively in neutral 3.5% NaCl solution were investigated using electrochemical impedance spectroscopy(EIS) and scanning electron microscope(SEM). It is found that the unstressed 1420 alloy is featured with large and discrete pits, while general corrosion and localized corrosion including intergranular corrosion and pitting corrosion occur on the unstressed 2195 alloy. As stress is applied to 1420 alloy, the pit becomes denser and its size is decreased. While, for the stressed 2195 alloy, intergranular corrosion is greatly aggravated and severe general corrosion is developed from connected pits. The EIS analysis shows that more severe general corrosion and localized corrosion occur on the stressed 2195 Al-Li alloy than on 1420 Al-Li alloy. It is suggested that tensile stress has greater effect on the corrosion of 2195 Al-Li alloy than on 1420 Al-Li alloy.

    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

    The laser-matter interaction acting during cw 2 kW Nd:YAG laser welding of an austenitic stainless steel is studied and particulary the effects linked to the presence of a keyhole in the liquid bath. This is done in order to define parameters useful to the process modelling. The absorption factor of target has been measured in order to better understand the Nd:YAG laser/stainless steel 304 interaction. Then an experimental approach of the keyhole angle value determination is proposed. Values are presented showing the important keyhole angle at the bottom of the bead. Finally a study relative to the plume above the keyhole shows that it is responsible for the formation of the nail-head part, observed on the experimental melting zone, by laser beam scattering. L'interaction laser-matière se produisant lors du soudage par laser Nd:YAG continu de 2kW d'un acier inoxydable austénitique est étudiée, et notamment les effets liés à la présence du capillaire dans le bain liquide, de façon à définir les paramètres utiles à la modélisation du processus. Le facteur d'absorption des cibles utilisées a été mesuré afin de mieux appréhender l'interaction laser Nd:YAG/acier inoxydable austénitique 304. Puis une approche expérimentale de détermination de l'angle d'inclinaison du capillaire est proposée. Des valeurs sont présentées montrant la forte inclinaison du capillaire en fond de cordon. Finalement une étude relative au panache présent audessus du capillaire met en évidence qu'il est responsable de la formation de la partie en tête de clou observée sur les zones fondues expérimentales par diffusion du faisceau laser

    Management of allied health staff and services often has implications for staff stability and retention. A survey of allied health staff in South West Victoria was conducted in 2003 to explore issues relating to recruitment and retention. Findings relating to management and retention of staff in their current job are addressed in this report. A total of 138 staff returned their questionnaires. Results were related to Maslow's hierarchy of needs, level of belonging, with professional needs identified as feeling supported, orientation to the position, clear job description, and able to recommend the position to others. Qualitative data showed that recommending the position was associated with job satisfaction, autonomy, flexibility, and variety of work. The immediate management structure was significantly related to retention. Reasons given for intending to leave were related to management categories. These were management structure, lack of career structure, and lack of professional support. Reasons given by respondents for not recommending their current position were as follows: not for long-term career, risk of deskilling if staying too long, and financially unrewarding. These reasons were also related to management. Positive reasons for staying, which were related to management, included flexible work conditions, variety of clinical and management experience, good working environment, good support, and autonomy. Recommendations are given for organizational development and training for managers.

Methods To compliment an EBP course for allied health care professionals and CAM practitioners, we undertook a questionnaire survey to assess learning needs. We developed a questionnaire to measure allied health care professionals and CAM practitioners' basic knowledge, skills and beliefs concerning the main principles of EBP. The questionnaires were administered to all attendees of one-day EBP workshops. Results During 2004–5 we surveyed 193 allied health care professionals and CAM practitioners who attended one-day EBP courses prior to commencement of teaching. Of the respondents 121 (62.7% were allied health care professionals and 65 (33.7% practitioners stated that they work in the CAM field Our survey found that the majority of the respondents had not previously attended a literature appraisal skills workshop (87.3% or received formal training in research methods (69.9%, epidemiology (91.2% or statistics (80.8%. Furthermore, 67.1% of practitioners specified that they felt that they had not had adequate training in EBM and they identified that they needed more training and education in the principles of EBM (86.7%. Differences in knowledge and beliefs concerning EBP amongst allied and CAM practitioners were found and length of time since qualification was also found to be an important factor in practitioner's beliefs. More CAM practitioners compared to allied health professionals accessed educational literature via the Internet (95.3% v 68.1%, p = 0.008. Whilst, practitioners with more than 11 years experience felt that original research papers were far more confusing (p = 0.02 than their less experienced colleagues.

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

    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 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.

Like other secondary effects of cancer treatment, these anticipated health risks should be addressed before the initiation of cancer treatment. While existing and emerging technologies may prevent or reduce risk of infertility (e.g., sperm, oocyte, embryo, or tissue banking), the lack of a trained workforce knowledgeable about oncology and reproductive health poses a barrier to care. The allied health professional (AHP) is a target of opportunity because of the direct and sustained patient relationships. Thus, developing tailored educational programs for nurses, social workers, psychologists, and physician assistants is an urgent unmet need toward field building. In this report, we outline results from a pilot study evaluating AHP perceptions of an oncology and reproductive health curriculum originally developed for nurses and adapted to meet the needs of several other AHP groups.

    In 1975 and 1976, eight teams of investigators located 262 colonies of nesting herons and their allies along the Atlantic coast from Florida to Maine. Fourteen species were found in Florida, numbers decreasing to seven in Maine. Colonies censused in the extreme south and north of the study area were lower in number of species and number of adults than those in the intermediate area. More than 90% of the colony sites surveyed in 1975 were active in 1976. The total number of nesting adults per colony, number of species per colony, and number of nestinga dults of each speciesp er colonyi n 1976 were significantlyc orrelatedw ith their respective values for 1975. Abandoned and new colonies appeared to be satellites of nearby reused colonies; they had fewer individuals and species than reused colonies and were closer to reused colonies than reused colonies were to each other.

    The effect of electric current pulse on the grain growth in the superplastic deformation of 2091 Al-Li alloy was investigated. Optical metallographic microstructure observation and average linear intercept measuring results show that at same strain, the grain size in the superplastic deformation loaded with electric current pulse is smaller than that unemploying electric current pulse, and so does the grain growth rate. TEM observation shows that the dislocation density at grain boundary in the superplastic deformation applied with electric current pulse is lower than that unemploying electric current pulse.It indicates that electric current pulse increases the rate of dislocation slip and climb in grain boundary, which leads to a decrease of both the density of the dislocation slipping across grain boundary at same strain rate and the driving force for grain growth, therefore the rate of grain growth decreases.The established model for grain growth shows an exponential relation of grain size with strain.

    Objective: The comparison of the remote and recent therapeutic effects on perennial allergic rhinitis was carried on among single application of acupoint-thread embedding, western medicine (certirizine + fl ixonase) and allied therapy. Method: Ninety cases were randomized into thread-embedding group, western medicine group and embedding+ western medicine group (allied-therapy group), 30 cases in each one.In thread embedding group, Yingxiang (迎香 LI 20) and Feishu (肺俞 BL 13) were selected for thread embedding, once a week, totally 4 treatments were required. In western medicine group, certirizine tablet 10 mg in combination with fl ixonase sprayer was applied once per day, continuously for 30 days in treatment.In allied-therapy group, both of the above methods were adopted continuously for 30 days in treatment. The therapeutic effects were in statistics at the end of treatment and 1 year later. Results: At the end of treatment, in thread-embedding group, 21 cases were remarkably effective, 3 cases effective and 6 cases no effect. In western medicine group, 20 cases were remarkably effective, 3 cases effective and 7 cases no effect. In allied-therapy group, 23 cases were remarkably effective, 2 cases effective and 5 cases no effect. It was shown in statistics that there was no significant difference in therapeutic effects among three groups (P>0.05). But one year after the end of treatment, it was indicated that in thread-embedding group, 3 cases were remarkably effective, 10 cases effective and 17 cases no effect; in western medicine group, 2 cases were remarkably effective, 9 cases effective and 19 cases no effect; in allied-therapy group, 7 cases were remarkably effective, 11 cases effective and 12 cases no effect. The significant difference in the therapeutic effects had not been presented in the comparison between thread-embedding group and western medicine group (P>0.05), but that had been presented between allied-therapy group with either of the

    While there has been a recent squeeze on staff costs, it continues to be important to offer graduating clinical staff National Health Service (NHS) employment in order to maintain the long-term strength of the service. In addition, the experiences of the Canadian nursing profession suggest that complacency about an improving recruitment situation can lead to problems. Consequently, the objective of this study was to identify what influences allied health professionals' (AHPs) intention to work for the NHS. A postal survey was sent to members of four Allied Health Professions equally (N = 4800), targeting Stayers in, Leavers from, and Returners to, the NHS. One thousand nine hundred and thirty-nine questionnaires were returned giving an overall response rate of 40%. Stayers' intention to remain in the NHS was influenced by continuing professional development opportunities, confidence that they can find NHS work, commitment to their profession, a sense of moral obligation and a belief that other people important to them think it is a good idea. Returners' intention is influenced by similar factors as Stayers. Leavers are influenced by similar factors as Stayers/Returners but to a lesser extent. The study shows that perceptions of various NHS work characteristics, which lead to reasonably positive attitudes towards the NHS, do not necessarily translate into intention to work for it. The study also shows that intention to work for the NHS is not solely dependent on perceptions of NHS jobs and that career-decision-making is a social process, with the opinions of people who are important to AHPs also influencing career decisions.

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 early results tend to validate the observations presented in this article. Cette étude réside dans la détermination expérimentale du comportement à la température ambiante de l'acier inoxydable 316 L sous chargement cyclique non proportionnel en traction-torsion-pressions interne et externe. Les deux ou trois déformations sinusoïdales appliquées sont soit en phase, soit hors-phase et l'on étudie l'amplitude du durcissement supplémentaire en fonction du degré de multiaxialité. On présente quelques boucles stabilisées typiques. Par rapport au durcissement supplémentaire maximal, les différents essais peuvent être classés comme suit: essais en phase (pas de durcissement supplémentaire), essais de traction-pressions hors-phase, essais de traction-torsion hors phase et essais de traction-torsion-pressions avec déphasages conséquents.

    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

  3. X-ray microtomography of fatigue crack closure as a function of applied load in Al-Li 2090 T8E41 samples

    Crack closure is held to be responsible for very low fatigue crack growth rates in many alloys such as Al-Li 2090 T8E41, and early crack face contact during unloading or prolonged contact during loading seems to reduce the driving force for crack extension. High resolution x-ray computed tomography (i.e., microtomography) allows one to image the entire volumes of samples and to quantify opening as a function of applied load over the entire crack surface. Crack closure results are reported for a fatigue crack grown under load ratio R = 0.1 in a compact tension sample of Al-Li 2090 T8E41; the crack was free to choose its path unconstrained by side-grooves which are normally used to suppress crack deflection. The inter-relationship between crack path, crack face contact and applied load level are discussed.

    The influence of tuning the laser 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 $\\delta^{'}$ 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 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 energy of 100 pJ was in fairly good agreement with reported range of $\\delta^{'}$ solvus temperature, suggesting a result of reversion upon heating due to laser pulsing.

    Introduction: 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.

    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.

    Ce travail contribue dans la modélisation du phénomène du soudage de l'acier inoxydable Austénitique 304L, afin d'étudier le comportement thermique d'un joint de soudure, obtenu par le procédé de soudage à l'arc électrique TIG (Tungsten-Inert-Gas). Le modèle simulant la source d'énergie de soudage, utilise une distribution surfacique Gaussienne du flux de chaleur provenant de l'arc électrique. La forme de cette source est supposée circulaire pour un premier cas et de forme bi-elliptique pour un second cas, tout en procédant à l'évaluation des champs et cycles thermiques à chaque instant, pour déterminer l'étendu des zones à risque, et l'effet de la vitesse de soudage sur ces dernières. Permettant ainsi de remonter par la suite, aux problèmes de contraintes résiduelles et déformations générées dans l'assemblage soudé. L'équation de chaleur régissant le problème est discrétisée par la méthode des volumes finis. Les calculs sont effectués en considérant que les propriétés physiques et thermiques ainsi que les conditions aux limites de convection et rayonnement, sont dépendante de la température. Pour évaluer la précision du modèle, une comparaison avec des mesures expérimentales de température d'un essai de soudage a été effectuée, les résultats indiquent un bon accord.

    Full Text Available We describe a new fossil species of Myriapora, M. sciutoi n. sp., which is similar in general appearance to the Recent, Atlantic, deep-sea species M. bugei d'Hondt, 1975. The new species has been found in sediments of the late Tortonian-Messinian of NW Morocco, and the Gelasian of NE Sicily and south Calabria, Italy. The main diagnostic characters of the new species are: erect, rigid growth, with lateral branches developing at right angles; arrangement of the zooids in whorls; dimorphic orifice, which has a very marked sinus in autozooids; prominent ooecia usually present in all the zooids from the same whorl. The previous diagnosis of the genus has been amended in order to include the presence of species with zooids arranged in whorls, in addition to those arranged quincuncially. A generic reassignment to Myriapora or to the allied genus Leieschara for all the known species to date is also proposed. The geographical and stratigraphical distribution of M. sciutoi n. sp. suggests a recolonization of the Mediterranean, after the Messinian Salinity Crisis, from founder populations that have survived in the Atlantic.

    The Forming Limit Curve (FLC) of the third generation aluminum-lithium (Al-Li) alloy 2198-T3 is measured by conducting a hemispherical dome test with specimens of different widths. The theoretical prediction of the FLC of 2198-T3 is based on the M-K theory utilizing respectively the von Mises, Hill’48, Hosford and Barlat 89 yield functions, and the different predicted curves due to different yield functions are compared with the experimentally measured FLC of 2198-T3. The results show that though there are differences among the four predicted curves, yet they all agree well with the experimentally measured curve. In the area near the planar strain state, the predicted curves and experimentally measured curve are very close. The predicted curve based on the Hosford yield function is more accurate under the tension-compression strain states described in the left part of the FLC, while the accuracy is better for the predicted curve based on Hill’48 yield function under the tension-tension strain states shown in the right part.

    2016-01-01

    Full Text Available The article analyses the problems which emerged on the eve of the Second World War: the European crisis of 1939, Anglo-French guarantees to countries of Eastern Europe, talks between the USSR, Great Britain and France and the Soviet-German non-aggression Pact. In conditions of the acutest crisis a question of general security acquired a key meaning. To stop the aggressor and to prevent global catastrophe was only possible by collective efforts of the great powers and their allies. Great Britain and France guaranteed independence of several countries of Eastern Europe, but they could not compensate the absence of a grand anti-German alliance. The USSR was striving to erect a system of collective security, but its possibilities were limited. More than that Great Britain and France did not refuse the idea of appeasing Germany at the expense of Poland, and this actually excluded their participation in anti-German coalition. The unwillingness of the Western powers to cooperate with the USSR closely showed itself at the AngloFrench-Soviet talks in spring and summer 1939. As a result of this the USSR, having no alternative, agreed to sign the non-aggression Pact with Germany.

    The Consultation and Relational Empathy (CARE) Measure (Mercer et al., 2004) is a patient-rated experience measure of practitioner empathy, developed and validated within adult health services. This study reports the feasibility, acceptability, reliability and validity of three adapted versions of the original CARE measure for the paediatric setting, namely the Visual CARE Measure 5Q, 10Q and 10Q Parent (also known as the Paediatric CARE Measure). Three hundred and sixty-nine participants (N = 149 children (40%) and N = 220 parents (60%)) completed the measure following consultation with an Allied Health Professional (AHP). AHPs felt it was feasible to use the measure in routine practice and the majority of children and parents found the measure easy to understand (98%) and complete (98%). Internal reliability (Cronbach's α) was .746 for the 5Q, .926 for the 10Q and .963 for the 10Q parent. Few participants used the 'not applicable' response (N = 28 (8%)), suggesting high content validity. AHPs found the measures relevant (95%) and useful (90%) and reported that they were likely to use them again (96%). The Visual CARE Measure shows promise as a useful tool to enable children and their parents to give their views. Further research on the tool's reliability and validity is required. PMID:25352539

    Full Text Available This study describes the relationship between two small and lesser states joining the German attack against Soviet Union in an attempt to recapture the territories lost to Soviet Union in 1940. It is conceived as an in-depth analysis of the Romanian-Finnish relations based on the criticism of archival sources discovered in the Romanian, Finnish and British archives. Becoming “allies without alliance” almost overnight, the relations between the two countries acknowledged a quick shift from low profile bonds to an agreement based on a combination of balance of power and joint action. The aim was to remove the threat Russia was posing to the two countries and to increase their influence at a peace conference to be open following the expected defeat of their big neighbour. Romania was the advocate of closer ties between the two countries keeping in line with its search for influence rather than autonomy in its foreign relations, while Finland was more prudent consistent with its choice for autonomy rather than influence.

    Objective: This paper provides an overview of the state of evidence-based practice (EBP) in nursing and selected allied health professions and a synopsis of current trends in incorporating EBP into clinical education and practice in these fields. This overview is intended to better equip librarians with a general understanding of the fields and relevant information resources. Included Professions: Professions are athletic training, audiology, health education and promotion, nursing, occupational therapy, physical therapy, physician assisting, respiratory care, and speech-language pathology. Approach: Each section provides a description of a profession, highlighting changes that increase the importance of clinicians' access to and use of the profession's knowledgebase, and a review of each profession's efforts to support EBP. The paper concludes with a discussion of the librarian's role in providing EBP support to the profession. Conclusions: EBP is in varying stages of growth among these fields. The evolution of EBP is evidenced by developments in preservice training, growth of the literature and resources, and increased research funding. Obstacles to EBP include competing job tasks, the need for additional training, and prevalent attitudes and behaviors toward research among practitioners. Librarians' skills in searching, organizing, and evaluating information can contribute to furthering the development of EBP in a given profession. PMID:17971887

  2. The ultilization of whole-body autoradiography and allied tracer techniques in distribution and biotransformation studies of N-nitrosamines

    International Nuclear Information System (INIS)

    The tissue disposition of various N-nitrosamines has been examined by whole-body autoradiography and allied tracer techniques in a series of studies. Tracing of N-nitrosamine-metabolizing tissues was a major purpose of the studies. The data obtained provide evidence that the in vivo localization of N-nitrosamine metabolites in various tissues is almost invariably due to local metabolism in the same tissues and that the tumourigenesis by N-nitrosamines is to a considerable extent correlated with this metabolism. The epithelial linings of the upper digestive tract and respiratory pathways were usually very active in N-nitrosamine metabolism, and these tissues also were prevalent sites for N-nitrosamine carcinogenesis. The presence of cytochrome P-450 activity has been shown in these structures and may normally play a role in defending the body against unrestrained uptake of xenobiotics. However, noxious effects may instead be induced for chemicals bioacivated by cytochrome P-450-dependent reactions, such as N-nitrosamines. (author)

    Allied health care professionals and nurses provide genetic-related client services, such as eliciting family medical history information and discussing the genetic component of health conditions. However, these professionals report a lack of confidence in their ability to perform genetic services and have little formal education in genetics. A barrier to incorporating genetics into allied health curricula includes the limited flexibility to expand curricula. This barrier was addressed by incorporating a Web-based tutorial on basic genetics and a lecture on the genetics of diabetes into preexisting undergraduate nutrition courses for nursing and dietetic students. The vast majority of students enrolled in these required courses participated in the intervention. Most participants agreed that genetics is important to their future career. Following the intervention, students' knowledge of genetics and confidence in their ability to provide genetic-related services increased significantly. Despite the short-term success and positive student evaluations, a single educational intervention does not appear to be sufficient for students to become proficient in performing the recommended genetic competencies for all health care professionals. Recommendations and resources for incorporating genetics into allied health curricula are included.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions 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.

    Purpose Despite having an obstetrician/gynecologist (ob/gyn) workforce comparable to the national average, Georgia is ranked 50th in maternal mortality and 40th in infant mortality. The Georgia Maternal and Infant Health Research Group (GMIHRG) was founded in 2010 to evaluate and address this paradox. Description In the several years since GMIHRG's inception, its graduate allied health student researchers and advisors have collaborated with community partners to complete several requisite research initiatives. Their initial work demonstrated that over half the Georgia areas outside metropolitan Atlanta lack adequate access to obstetric services, and their subsequent research evaluated the reasons for and the consequences of this maldistribution of obstetric providers. Assessment In order to translate their workforce and outcomes data for use in policymaking and programming, GMIHRG created reader-friendly reports for distribution to a wide variety of stakeholders and prepared concise, compelling presentations with targeted recommendations for change. This commitment to advocacy ultimately enabled them to: (a) inspire the Georgia Study Committees on Medicaid Reform and Medical Education, (b) influence Georgia General Assembly abortion bills, medical scholarship/loan legislation, and appropriations, and (c) motivate programming initiatives to improve midwifery education and perinatal regionalization in Georgia. Conclusion GMIHRG members have employed inventive research methods and maximized collaborative partnerships to enable their data on Georgia's maternal and infant outcomes and obstetric workforce to effectively inform state organizations and policymakers. With this unique approach, GMIHRG serves as a cost-efficient and valuable model for student engagement in the translation of research into advocacy efforts, policy change, and innovative programming.

    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.

    Background Implementation of evidence-based practice (EBP) is regarded as core competence to improve healthcare quality. In the current study, we investigated the EBP of six groups of professionals: physicians, nurses, pharmacists, physical therapists, technicians, and other allied healthcare personnel. Methods A structured questionnaire survey of regional hospitals throughout Taiwan was conducted by post in 2011. Questionnaires were mailed to all healthcare workers of 11 randomly selected hospitals. Linear and logistic regression models were used to examine predictors for implementing EBP. Results In total, 6,160 returned questionnaires, including 645 from physicians, 4,206 from nurses, 430 from pharmacists, 179 from physical therapists, 537 from technicians, and 163 from other allied healthcare professionals, were valid for the analysis. Physicians and pharmacists were more aware of EBP than were the other professional groups (p < 0.001). Positive attitudes toward and beliefs in EBP were significantly lower among nurses than in the other groups (p < 0.001). Physicians had more sufficient knowledge and skills of EBP than did the other professionals (p < 0.001); in addition, they implemented EBP for clinical decision-making more often and perceived fewer personal barriers to EBP (p < 0.001). Multivariate logistic regression analyses showed that EBP implementation was associated with the following characteristics of participants: EBP training, having a faculty position, academic degree, one's profession, and perceptions (beliefs, attitudes, knowledge, skills and barriers). Conclusions This study depicts various levels of EBP implementation among medical, nursing, pharmacological, and allied healthcare personnel. There were significant differences in their implementation of EBP. We observed that certain factors were associated with EBP implementation, including personal backgrounds and perceptions toward EBP. The data suggest that strategies for

    Types of social media (Web 2.0) usage associated with eight of Australia's major allied health professions (AHPs, n = 935) were examined. Australian AHPs are interacting with Web 2.0 technologies for personal use but are failing to implement such technologies throughout their health professions to deliver health care. Australian AHPs are willing to undertake online educational courses designed to up skill them about how Web 2.0 may be used for practice promotion and health care delivery in the early twenty-first century. Participants in this study indicated that educational courses that were offered online would be the preferred mode of delivery.

    A major research plan entitled "Integrated research on the eco-hydrological process of the Heihe River Basin" was launched by the National Natural Science Foundation of China in 2010. One of the key aims of this research plan is to establish a research platform that integrates observation, data management, and model simulation to foster 21st-century watershed science in China. Based on the diverse needs of interdisciplinary studies within this research plan, a program called the Heihe Watershed Allied Telemetry Experimental Research (HiWATER) is implemented. The overall objective of HiWATER is to improve the observability of hydrological and ecological processes, to build a world-class watershed observing system and to enhance the application ability of remote sensing in integrated eco-hydrological study and water recourse management at basin scale. We introduce the background, scientific objectives and experimental design of the HiWATER. The highlights are using flux observing matrix and eco-hydrological wireless sensor network to capture multi-scale heterogeneities, in order to challenge the complex issues such as heterogeneity, scaling, uncertainty, and closing water cycle at watershed scale. HiWATER has formally kicked off in May 2012 and will last four years till 2015. HiWATER encompasses fundamental experiments, thematic experiments, application experiments, remote sensing methods development and products generation, and an integrated information system. (1) Fundamental experiments: a) Microwave radiometer, imaging spectrometer, thermal imaging camera, light detection and ranging (LiDAR) and other sensors are used in the airborne missions to observe key eco-hydrological parameters. b) A comprehensive hydrometeorological observation network has been established in the entire Heihe River Basin, in order to provide more representative model parameters and forcing data. c) An eco-hydrological wireless sensor network (WSN) has been installed to capture the spatial

    Full Text Available Abstract Background Despite a recent increase in activities to promote evidence-based practice (EBP, it was unclear how Malaysian hospital practitioners received this new approach in medicine. This study examines their confidence and perceptions on EBP. Findings We conducted cross-sectional surveys using a self-administered questionnaire during two EBP training courses in two Malaysian hospitals in January and June 2007. Our subjects (n = 144 were doctors and nursing and allied health staff (NAH participating in the EBP courses. Our questionnaire covered three domains: confidence and understanding (six items, attitude (five items and barriers to practice (four items. We presented simple descriptive statistics, including the sum ratings and the proportions with different responses for each item, and compared different groups using Mann-Whitney U test for scaled ratings and Chi-square test for dichotomous responses. Ninety-two doctors and 52 NAH staff completed the surveys. Overall, doctors expressed slightly higher confidence on EBP compared to NAH staff. Out of a maximum sum rating of 27 over six items, doctors reported an average of 18.3 (SD 3.2 and NAH staff reported an average of 16.0 (SD 3.4, p = 0.002. Doctors were also more positive in their views on EBP. For example, 67.4% of doctors disagreed, but 61% of NAH staff agreed that "the importance of EBP in patient care is exaggerated", and 79.3% of doctors disagreed, but 46.2% of NAH staff agreed that "EBP is too tedious and impractical". Similar responses were observed for other items in the domain. Doctors and NAH staff shared similar concerns on barriers to evidence-based practice. The highest proportions considered poor facilities to access evidence a barrier (76% of doctors and 90% of NAH, followed by poor awareness of evidence (62% of doctors and 70% of NAH and time constraints (63% of doctors and 68% of NAH, p = 0.09 for the combined rating of four items in the domain.

    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.

    2016-06-14

    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.

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.

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.

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The behavior of growth and coarsening of T1(Al2CuLi) precipitates was comparatively studied by means of TEM technique in two Al-Li alloys 2090 and 2090+Ce (with cerium content less than 0.1% in mass fraction). Statistical analysis results show that T1 precipitates in alloy 2090+Ce have smaller aspect ratio, which is connected with the more intersections between different T1 variants in this alloy. It is also found that the variation of maximum length of T1 precipitates with aging time can be obviously divided into two stages of growth and coarsening. The diffusion coefficients of solute atoms of Cu and Li are calculated via growth kinetics curves of T1 precipitates. The results show that the diffusion of atom Cu plays a more important role in the formation of T1 precipitates.

  2. Aluminum alloys for ALS cryogenic tanks: Comparative measurements of cryogenic mechanical properties of Al-Li alloys and alloy 2219, February 1993

    International Nuclear Information System (INIS)

    Tensile and fracture toughness were obtained at cryogenic temperatures to compare the Al-Li alloys 8090, 2090, and WL049, and alloy 2219 in various tempers and specimen orientations. The strongest alloy at very low temperatures is WL049-T851, which is about 10 percent stronger than 2090-T81. Both alloys are considerably stronger than 2219-T87. Alloy 2090-T81 is tougher (about 50 percent) than WL049-T851 at low temperatures; the higher toughness is attributed to the presence of fewer constituent particles and the tendency to delaminate at low temperatures. The delamination divides the moving crack, thus separating it into smaller regions where plane stress (rather than plane strain) conditions are conducive to increased toughness

    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

    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 %).

    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. Work and age-related factors that exacerbate difficulties include vision and hearing deficits, increasing tiredness, more complex

    Full Text Available Abstract Background Variability between clinical practice guideline recommendations and actual clinical practice exists in many areas of health care. A 2004 systematic review examining the effectiveness of guideline implementation interventions concluded there was a lack of evidence to support decisions about effective interventions to promote the uptake of guidelines. Further, the review recommended the use of theory in the development of implementation interventions. A clinical practice guideline for the management of acute low-back pain has been developed in Australia (2003. Acute low-back pain is a common condition, has a high burden, and there is some indication of an evidence-practice gap in the allied health setting. This provides an opportunity to develop and test a theory-based implementation intervention which, if effective, may provide benefits for patients with this condition. Aims This study aims to estimate the effectiveness of a theory-based intervention to increase allied health practitioners' (physiotherapists and chiropractors in Victoria, Australia compliance with a clinical practice guideline for acute non-specific low back pain (LBP, compared with providing practitioners with a printed copy of the guideline. Specifically, our primary objectives are to establish if the intervention is effective in reducing the percentage of acute non-specific LBP patients who are either referred for or receive an x-ray, and improving mean level of disability for patients three months post-onset of acute LBP. Methods The design of the study is a cluster randomised trial. Restricted randomisation was used to randomise 210 practices (clusters to an intervention or control group. Practitioners in the control group received a printed copy of the guideline. Practitioners in the intervention group received a theory-based intervention developed to address prospectively identified barriers to practitioner compliance with the guideline. The

Currently, self-management varies widely. Little is known either about nurses’ and allied health professionals’ (AHPs’ understanding and provision of self-management in clinical practice. This study explores nurses’ and AHPs’ understanding and implementation of supported COPD self-management within routine clinical practice. Materials and methods: Nurses and AHPs participated in face-to-face semistructured interviews to explore their understanding and provision of COPD self-management, as well as their perceptions of the challenges to providing such care. Purposive sampling was used to select participants from a range of professions working within primary, community, and secondary care settings. Three researchers independently analyzed each transcript using a thematic approach. Results: A total of 14 participants were interviewed. Nurses and AHPs viewed self-management as an important aspect of COPD care, but often misunderstood what it involved, leading to variation in practice. A number of challenges to supporting self-management were identified, which related to lack of time, lack of insight regarding training needs, and assumptions regarding patients’ perceived self-management abilities. Conclusion: 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

    In this study, an effective and precise fluorescent molecularly imprinted polymers (FMIPs) for the determination of Beta-Cyfluthrin (BC) was synthesized via precipitation polymerization with SiO2 as the carrier, BC as the target molecule, ally fluorescein as the functional monomer, trimethylolpropane trimethacrylate (TRIM) as the crosslinker. Moreover, the characteristic of material has been measured by FTIR, TEM, SEM, TGA, LSCM and fluorescence spectrophotometer. Average diameter and shell thickness of as-synthesized microspheres were 300nm and 50nm, respectively. An excellent linear relationship of SiO2-MPTMS@FMIPs with a correlation coefficient of 0.9919 could be gained covering a wide concentration range of 10.11-80nM described by the Stern-Volmer equation. The limit of detection (LOD) was evaluated with the equation LOD=3σ/S and was found to be 10.11nM. The study demonstrated that SiO2-MPTMS@FMIPs could improve the determination for BC and illustrated the good prospects of SiO2-MPTMS@FMIPs for BC detection in agricultural products. PMID:27664679

The analysis was conducted in multiple sections of three different introductory microbiology classes targeting specific cohorts: nursing students, pharmacy students and other allied health students (pre-med, pre-PA, CLS, etc.. Retention of course content was determined by evaluation of multiple-choice and short answer examinations at least three weeks after completing case studies. Evaluation of patient empathy, understanding of patient compliance issues and transcultural health care concerns were determined via student surveys. The results of the study indicated that personalized cases significantly improved long-term retention of course content. In addition, student responses indicated that personalized case studies were more effective in developing patient empathy and aiding students in understanding issues patients have with complying with treatment recommendations. Finally, personalized case studies were effective tools for introducing students to the challenges of transcultural health care.

    Based on a novel high strength Al-Cu-Li-X alloy-2A97, the effect of T6I6 and its modified processes on the properties investigated by SEM and tensile test. The results show that when the alloy is heat treated by triple ageing, with secondary low temperature ageing at 80 ℃ after initial ageing at 155 and 150 ℃, and final re-ageing at 135 and 165 ℃, the tensile properties are close to the peak level of aged alloy in T6 temper. The addition of plastic deformation after and prior to secondary ageing favor the T1(Al2CuLi) and δ'(Al3Li) precipitation during final re-ageing at 135 and 165 ℃ corresponding to triple ageing, so the Al-Li alloy displays higher strength for the modified processes of T6I6. The microstructures consist of δ', T1 and θ"/θ' (Al2Cu) phase for single and triple aged alloy, the number density and volume fraction of δ' phase increase for T6I6 and its modified processes correspond to single ageing.

    Cocaine is a stimulant drug of the central nervous system (CNS) extracted from the leaves of Erytroxylum coca. It is defined as a tropane alkaloid containing 1R-(exo,exo)-3-(benzoyloxy)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylic acid methyl esther. However, despite its defined composition, a wide variety of chemical additives are present in cocaine found in the illicit market, such as benzocaine, lidocaine, caffeine, procaine and phenacetin. In this work, 512 cocaine samples seized by the Civil Police of Espirito Santo state (PC-ES, Brazil) were analyzed by gas chromatography mass spectrometry (GC-MS) allied to principal component analysis (PCA) in order to classify the samples as a function of seizure year (2008, 2009, 2010, 2011 and 2012) and location (metropolitan, north, south and central). The cocaine content (wt.%) and its adulterants were also estimated. Analyzing the samples seized between 2008 and 2011, three sample sets are clearly grouped according to the degree of adulteration with caffeine and lidocaine: 100-50 wt.% of cocaine; 50-20 wt.% of cocaine; and 20-80 wt.% of lidocaine and 60-80 wt.% of caffeine, simultaneously. The last group is formed by samples seized between 2008 and 2009, which proves the higher degree of adulteration during this period. In 2012, higher cocaine content was observed for the 191 analyzed samples than in samples from previous years. The PCA data also suggests that the metropolitan region samples had a higher degree of adulteration than the state countryside samples. PMID:26976463

    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

    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.

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

    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.

    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.

    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.

    Full Text Available Les recherches récentes en histoire sociale et culturelle sur la Grande Guerre s’intéressent notamment à l’étude de la production littéraire, médiatique et iconographique comme pratique signifiante et représentative de l’expérience individuelle et collective de la guerre, ce que les historiens identifient comme les « cultures de guerres ». Ces « cultures de guerre » sont analysées, entre autres, à partir de la presse, dont la situation privilégiée au carrefour de l’opinion publique et de la propagande gouvernementale, en fait un objet d’étude significatif pour mieux comprendre la mobilisation des populations dans le cadre d’une guerre totale. À partir d’une approche interdisciplinaire, notre article a pour principal objectif de dégager et d’analyser les stéréotypes qui règlent les représentations de l’allié russe dans la presse illustrée française durant la Grande Guerre. Plus précisément, nous voulons interroger l’évolution des représentations de la figure du combattant russe afin de dégager dans quelle mesure il y a eu rupture ou permanence des représentations, en fonction de l’évolution du contexte historique entre 1914 et 1920.Recent research in the social and cultural history of the Great War views literary, media, and iconographic productions as a significant aspect of the individual and collective war experience, and scholars see these productions as forming « war cultures ».

  4. Carotenoids: potential allies of cardiovascular health?

    Directory of Open Access Journals (Sweden)

    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.

    1993-12-01

    Alternating Wenckebach periods (AWPs) are episodes of 2:1 block during which the PR, AH, or AV intervals of the conducted beats gradually increase until a greater degree of block ensues. Most episodes occur at the AV node, but some have also been reported in other structures. AWPs are usually attributed to multilevel block due to transverse (horizontal) dissociation. This assumption was initially based on a method in which the solutions to difficult electrocardiographic rhythms were arrived at by analysis and deduction based on the knowledge existing at that particular time. Subsequently, it was reinforced by information extrapolated from intracardiac recordings performed in patients with documented multilevel block in separate anatomical structures (atria, AV node, and His bundle), as well as from microelectrode studies and computer simulations. Although AWPs are frequently observed in clinical tracings, those occurring at the AV node are best categorized during incremental atrial stimulation because then they occupy a specific point in the wide spectrum of tachycardia dependent AV nodal conduction disturbances. In fact, the A:H ratios occurring in the episodes where the degree of block increases can be represented by "universal" mathematical formulas. However, in the clinical setting, drugs affecting the electrophysiology of the node can alter the pacing induced symmetry by producing additional differential effects on the various levels. The latter still requires further elucidation. PMID:7508606

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

    Energy Technology Data Exchange (ETDEWEB)

    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)

    Full Text Available Statistics of extremes in poorly gauged basins: application of a lumped rainfall-runoff model in five catchments area in Walloon region (Belgium. The RS-PDM© model generates flows in time series on the basis of observed rainfall after self-calibration which is based on short period of observed rainfall and flow. This is done with daily or hourly data. The study highlights the capacity of the RS-PDM© model to simulate extreme flows in poorly gauged basins in Walloon region on the basis of observed rains and of a short period of observed flows. Concerning the time series, it was highlighted an important dispersion of the flows simulated for a given observed flow even for daily or hourly data. The Nash criteria varied between 0.59 and 0.92. However, the flows simulated via RS-PDM© make it possible to adjust a statistical distribution of extremes flows (Gumbel law close to the statistic obtained with a long period of gauging. So, if the simulations realized by mean of this model present poor to acceptable performances concerning the time series simulations, they permit to obtain rapidly quite good statistics of extremes flows on the basis of a short gauging period.

    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...

    Translational research is changing the practice of modern medicine and the way in which health problems are approached and solved. The use of small-animal models in basic and preclinical sciences is a major keystone for these kinds of research and development strategies, representing a bridge between discoveries at the molecular level and clinical implementation in diagnostics and/or therapeutics. The development of high-resolution in vivo imaging technologies provides a unique opportunity for studying disease in real time, in a quantitative way, at the molecular level, along with the ability to repeatedly and non-invasively monitor disease progression or response to treatment. The greatest advantages of preclinical imaging techniques include the reduction of biological variability and the opportunity to acquire, in continuity, an impressive amount of unique information (without interfering with the biological process under study) in distinct forms, repeated or modulated as needed, along with the substantial reduction in the number of animals required for a particular study, fully complying with 3R (Replacement, Reduction and Refinement) policies. The most suitable modalities for small-animal in vivo imaging applications are based on nuclear medicine techniques (essentially, positron emission tomography [PET] and single photon emission computed tomography [SPECT]), optical imaging (OI), computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance spectroscopy imaging (MRSI), and ultrasound. Each modality has intrinsic advantages and limitations. More recently, aiming to overcome the inherent limitations of each imaging modality, multimodality devices designed to provide complementary information upon the pathophysiological process under study have gained popularity. The combination of high-resolution modalities, like micro-CT or micro-MRI, with highly sensitive techniques providing functional information, such as micro-PET or micro-SPECT, will continue to broaden the horizons of research in such key areas as infection, oncology, cardiology, and neurology, contributing not only to the understanding of the underlying mechanisms of disease, but also providing efficient and unique tools for evaluating new chemical entities and candidate drugs. The added value of small-animal imaging techniques has driven their increasing use by pharmaceutical companies, contract research organizations, and research institutions. PMID:24146172

    Linton, Harold E.

    2002-06-01

    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.

    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.

    2016-05-01

    Electron collisions with atoms, ions, and molecules represent one of the very early topics of quantum mechanics. In spite of the field's maturity, a number of recent developments in detector technology (e.g., the ``reaction microscope'' or the ``magnetic-angle changer'') and the rapid increase in computational resources have resulted in significant progress in the measurement, understanding, and theoretical/computational description of few-body Coulomb problems. Close collaborations between experimentalists and theorists worldwide continue to produce high-quality benchmark data, which allow for thoroughly testing and further developing a variety of theoretical approaches. As a result, it has now become possible to reliably calculate the vast amount of atomic data needed for detailed modelling of the physics and chemistry of planetary atmospheres, the interpretation of astrophysical data, optimizing the energy transport in reactive plasmas, and many other topics - including light-driven processes, in which electrons are produced by continuous or short-pulse ultra-intense electromagnetic radiation. In this talk, I will highlight some of the recent developments that have had a major impact on the field. This will be followed by showcasing examples, in which accurate electron collision data enabled applications in fields beyond traditional AMO physics. Finally, open problems and challenges for the future will be outlined. I am very grateful for fruitful scientific collaborations with many colleagues, and the long-term financial support by the NSF through the Theoretical AMO and Computational Physics programs, as well as supercomputer resources through TeraGrid and XSEDE.

  15. The media and the military: Allies or adversaries?

    2012-02-01

    Full Text Available Military commanders like Alexander the Great or Richard the Lionheart did not have to take public opinion greatly into account when they planned their campaigns in their day. Today it is a very different situation. In the light of the above this article starts with two somewhat startling quotes by the futurologists Alvin and Heidi Toffler: "The people thinking hardest about warfare in the future know that some of the most important combat of tomorrow will take place on the media battlefield." They also state: “[T]he media, including channels and technologies unimagined today, will be a prime weapon for Third Wave combatants in both the wars and anti-wars of the future, a key component of knowledge strategy.” In recent years, much has been made of the adversarial relations between journalists and the military. The media have, for instance, been blamed for the US defeat in Vietnam, for unthinkingly blabbing about tactical decisions in advance in the Falklands, etc. From their side, journalists have been blaming the military for not trying to understand the nature of their job, of covering up a number of bad things, etc.

  16. Turning symptoms into allies: utilization approaches with posttraumatic symptoms.

    Science.gov (United States)

    Phillips, M

    1993-01-01

    Adult patients with symptoms connected to the trauma of childhood sexual abuse often present in therapy with multiple symptoms and life difficulties and offer a challenge to even the most experienced clinician. In this paper, I describe my work with three such patients who were crippled in different ways by symptoms that had proved resistant to years of various therapeutic interventions. In every case, I accepted and utilized these symptoms as positive resources for successful and rapid change. Patients were then taught self-utilization approaches which allowed them to sustain and extend initial improvements. I conclude that the indirect utilization principle introduced by Milton Erickson provides an effective method to use in approaching some of the more persistent patterns of posttraumatic symptomatology related to childhood sexual abuse.

  17. 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.

    2013-03-14

    Non-communicable diseases (NCD) are a major and increasing contributor to morbidity and mortality in developed and developing countries. Much of the chronic disease burden is preventable through modification of lifestyle behaviours, and increased attention is being focused on identifying and implementing effective preventative health strategies. Nutrition has been identified as a major modifiable determinant of NCD. The recent merging of health economics and nutritional sciences to form the nascent discipline of nutrition economics aims to assess the impact of diet on health and disease prevention, and to evaluate options for changing dietary choices, while incorporating an understanding of the immediate impacts and downstream consequences. In short, nutrition economics allows for generation of policy-relevant evidence, and as such the discipline is a crucial partner in achieving better population nutritional status and improvements in public health and wellness. The objective of the present paper is to summarise presentations made at a satellite symposium held during the 11th European Nutrition Conference, 28 October 2011, where the role of nutrition and its potential to reduce the public health burden through alleviating undernutrition and nutrition deficiencies, promoting better-quality diets and incorporating a role for functional foods were discussed.

    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

    2011-05-01

    The reorientation of a water molecule is important for a host of phenomena, ranging over—in an only partial listing—the key dynamic hydrogen-bond network restructuring of water itself, aqueous solution chemical reaction mechanisms and rates, ion transport in aqueous solution and membranes, protein folding, and enzymatic activity. This review focuses on water reorientation and related dynamics in pure water, and for aqueous solutes with hydrophobic, hydrophilic, and amphiphilic character, ranging from tetra-methylurea to halide ions and amino acids. Attention is given to the application of theory, simulation, and experiment in the probing of these dynamics, in usefully describing them, and in assessing the description. Special emphasis is placed on a novel sudden, large-amplitude jump mechanism for water reorientation, which contrasts with the commonly assumed Debye rotational diffusion mechanism, characterized by small-amplitude angular motion. Some open questions and directions for further research are also discussed.

  10. Controle sismique d'un batiment en acier de 1 etage par amortisseurs elastomeres et contreventements en Chevron

    Girard, Olivier

    Actuellement, le principe de dimensionnement a la capacite est fortement utilise dans le domaine du genie parasismique. De maniere simplifiee, cette methode de dimensionnement consiste a dissiper l'energie injectee a une structure lors d'une secousse sismique par la deformation inelastique d'un element structural sacrificiel. Cette methode de dimensionne-ment permet d'obtenir des structures economiques, car cette dissipation d'energie permet de reduire substantiellement les efforts qui se retrouvent a l'interieur de la structure. Or, la consequence de ce dimensionnement est la presence de degats importants a la structure qui suivent a la secousse sismique. Ces degats peuvent engendrer des couts superieurs aux couts d'erection de la structure. Bien entendu, sachant que les secousses sismiques d'importances sont des phenomenes rares, l'ingenieur est pret a accepter ce risque afin de diminuer les couts initiaux de construction. Malgre que cette methode ait permis d'obtenir des constructions economiques et securitaires, il serait interessant de developper un systeme qui permettrait d'obtenir des performances de controle des efforts sismiques comparables a un systeme dimensionne selon un principe de dimensionnement a la capacite sans les consequences negatives de ces systemes. En utilisant les principes d'isolation a la base, il a ete possible de developper un systeme de reprise des forces sismiques (SRFS). qui permet d'obtenir un controle des efforts sismiques concurrentiels tout en gardant une structure completement elastique. Ce systeme consiste u inserer un materiel elastomere entre l'assemblage de la poutre et des contreventements a l'interieur d'un cadre contrevente conventionnel. Cette insertion permet de diminuer substantiellement la rigidite laterale du batiment, ce qui a pour consequence d'augmenter la valeur de la periode fondamentale du batiment dans lequel ces cadres sont inseres. Ce phenomene est appele le saut de periode. Ce saut de periode permet de reduire grandement l'amplification dynamique essuyee lors d'un seisme du au contenu frequentiel particulier des secousses sismiques. Toutefois, la reduction de la rigidite globale a pour consequence d'augmenter grandement les deplacements de fonctionnement de la structure, ce phenomene etant mitige par les proprietes amortissantes de l'elastomere utilise. Le SRFS propose a ete etudie dans le cadre de la presente maitrise. Les objectifs de l'etude consistent a demontrer l'efficacite et la faisabilite du systeme propose ainsi que de developper une methode de dimensionnement efficace et securitaire pour ce genre de systeme. Afin de faciliter l'obtention des objectifs, l'approche qui a ete utilisee est l'etude comparative d'un meme batiment dimensionne selon deux principes. Le premier est le dimensionnement a la capacite. Le second est un dimensionnement employant le systeme propose. La presente etude a ete scindee en quatre parties distinctes. La premiere est l'etude du materiel elastomere afin de determiner les proprietes utiles lors d'un dimensionnement. La seconde est le dimensionnement et l'etude en laboratoire du comportement d'un cadre contrevente selon un principe de dimensionnement a la capacite. La troisieme partie est le dimensionnement et l'etude en laboratoire du comportement d'un cadre contrevente integrant des amortisseurs elastomeres. La quatrieme et derniere partie est l'etude comparative des performances sismiques d'un batiment qui emploie des cadres amortis avec des amortisseurs elastomeres avec les performances d'un batiment qui emploie un SRFS par contreventements classiques. A la suite des differentes analyses, il a ete possible de conclure sur les performances du systeme propose employant des amortisseurs elastomeres. Le systeme possede un excellent comportement quant aux sollicitations sismiques. Le controle des efforts sismiques est du meme ordre qu'un SRFS par contreventements de ductilite moderee (reduction des efforts elastiques par un facteur de 3). Bien que la demande en deplacement soit plus grande pour le systeme propose que pour un syst

    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)

    Welding is a highly used assembly technique. Welding simulation software would give access to residual stresses and information about the weld's microstructure, in order to evaluate the mechanical resistance of a weld. It would also permit to evaluate the process feasibility when complex geometrical components are to be made, and to optimize the welding sequences in order to minimize defects. This work deals with the numerical modelling of arc welding process of steels. After describing the industrial context and the state of art, the models implemented in TransWeld (software developed at CEMEF) are presented. The set of macroscopic equations is followed by a discussion on their numerical implementation. Then, the theory of re-meshing and our adaptive anisotropic re-meshing strategy are explained. Two welding metal addition techniques are investigated and are compared in terms of the joint size and transient temperature and stresses. The accuracy of the finite element model is evaluated based on experimental results and the results of the analytical solution. Comparative analysis between experimental and numerical results allows the assessment of the ability of the numerical code to predict the thermomechanical and metallurgical response of the welded structure. The models limitations and the phenomena identified during this study are finally discussed and permit to define interesting orientations for future developments. (author)

    The wear behaviour of an austenitic stainless steel is analysed using a tribometer working in pressurised high temperature water (PHTW). The precise contact conditions, low pressure impact and sliding contacts, play an important role on the surface wear in this corrosive medium. The tests which include both impact and sliding are the most severe. The friction films formed during these tests are compared with those obtained with pure oxidation. It is shown that these films participate in the formation of elongated 'indents' observed on the surfaces. Nano-indentation measurements consolidate this hypothesis.

    The inner surface of vessels of pressurized water reactor is protected from corrosion by a stainless steel cladding hot-layer in many cuts. Therefore, the surface irregularities generate spurious echoes that can either mask or be misinterpreted for echoes from possible defects. Probes are calibrated on a specific reflector (side drilled holes in a steel block). The echo arising from it is used as a reference to quantify echoes measured during an examination. The study aims at simulating echographs of the vessel inspection so as to help the analysis of actual measurements. Three models are developed to compute echoes from cladding surface irregularities, echoes from planar defects and the reference echo, respectively. The radiated field is modelled using the Rayleigh integral, the integration of the incident beam with the cladded surface is treated under Kirchhoffs approximation and the reception of reflected waves involves reciprocity between radiation and reception. An extra physical hypothesis allows a fast algorithm to be developed for simulating the Bscan image obtained by transducer scan. The reference echo is also computed under Kirchhoffs approximation. The field refracted inside the material is modelled by an extension of the Rayleigh integral using the geometrical optics approximation. The model for computing diffracted echoes from crack tips is based upon the Geometric Theory of Diffraction. The model for predicting echoes from cladded surface irregularities has been validated by comparing theoretical predictions with experimental measurements. (author). 48 refs.

    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)

    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.

    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)

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.

    Danieli has developed a complete integrated metallurgical process for the newer mini-mills. It assures prime quality of the products, an attractive reduction of the production cost through energy and storage savings, an improved satisfaction of the customer with short delivery times. It consists in direct rolling of blooms or billets coming from the continuous caster; it is named the Black Box concept. This implies and entirely new approach of the mill design and operation. Three sites are now producing using this concept and two are scheduled to be commissioned in 1998. (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.)

  13. Study of stress relief cracking in titanium stabilized austenitic stainless steel; Etude de la fissuration differee par relaxation d'un acier inoxydable austenitique stabilise au titane

    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)

    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 work deals with gaseous hydrogen embrittlement of steels for pipelines having a relatively high mechanical resistance (elasticity limit: 550 MPa, Grade 80). The studied materials come from 5 tube steels batch already used for hydrocarbons transport. Plates have been obtained by continuous casting followed by a hot controlled rolling: the rolling temperature is adjusted for obtaining a strain hardening in order to increase the mechanical resistance of the steel. These materials have been tested under hydrogen pressure and the resistance to hydrogen has been measured for each of them. The results show that the hydrogen embrittlement decreases when the mechanical resistance of the plate (or its hardness) increases. The inclusion state of the different steels has been quantified by images analysis at different depths in the plates. These steels contain only globular oxides or aligned aluminates. The hydrogen embrittlement increases with the amount of the globular oxides (or with the length of the aligned aluminates). Micrographic and fractographic analyses show that even small globular inclusions ({phi}=1 {mu}m) concentrate enough hydrogen to induce a crack in the material or to lead to a crack propagation. In order to estimate the homogeneity of the ferrito-perlitic structure, the thickness of ferrite bands have been measured. The hydrogen embrittlement increases as the thickness of the ferrite bands, that is to say, as the heterogeneity of the structure. Micrographs have shown that the hydrogen cracking is initiated on perlite aggregates; the crack propagates then in ferrite and joins then others perlitic areas. This study shows that relatively resistant steels (Grade 80, elasticity limit: 550 MPa) can be used for manufacturing pipelines submitted to high hydrogen pressure. (O.M.)

    Ste-Marie, Michael

    Stainless Steel and Superalloy parts have been obtained by Maetta metal injection molding process to understand the sintering and to build a model of the shrinkage and the density by DOE after sintering. Maetta process consists of low pressure injection molding; this technology is competitive for medium series and complex geometries. The experimental procedure shows how to reduce the dimensions variability and to optimise the cost and the mechanical properties for the chosen alloys on Maetta equipments. The parts have been injected with a Maetta mixer and pneumatic presses. After that, the binder removal was done by capillary debinding. All sintering have been managed following a design of experiment (DOE) plan. The results of density measured by the Archimede's method and shrinkage were obtained by a regression model as a function of final heating ramp, soaking temperature and time. The simulation predicts experimental results with a relative error of 0,25% on the density and 2,2% for the shrinkage. The model is a good way to begin a complete simulation that regroups all effects on the dimensions of sintered parts for the Maetta process. The effects of the geometry, powder characteristics and debinding step on density and dimensions after sintering are not added in this study. Other studies would be necessary to build a global simulation.

    Usually, the irradiation of polymers under ionising radiations occurs in air that is in the presence of oxygen. This leads to a radio oxidation process and to oxygen consumption. Our material is an EPDM elastomer (ethylene propylene 1,4 hexadiene) used as insulator in control-command cables in nuclear plants (Pressurised Water Reactor). A specific device has been conceived and built up during this PhD work for measuring very small oxygen consumptions with an accuracy of around 10%. Ionising radiations used are electrons at 1 MeV and carbon ions at 11 MeV per nucleon. Under both electron and ion irradiations, the influence of oxygen pressure on oxygen consumption has been studied in a very large range: between 1 and 200 mbar. In both cases, the yield of oxygen consumption is constant in-between 200 and 5 mbar. Then, at lower pressures, it decreases appreciably. On the other hand, the oxygen consumption during ion irradiation is four times smaller than during electron irradiation. This emphasizes the role of the heterogeneity of the energy deposition at a nano-metric scale. The adjustment of the experimental results obtained during electron irradiation with the general homogeneous steady-state kinetic model has allowed extracting all the values of the kinetic parameters for the chosen mechanism of radio oxidation. The knowledge of these numbers will allow us to face our results obtained during ion irradiation with a heterogeneous kinetic model under development. (author)

    Information on the structure, spectroscopy and target interaction potentials of exotic nuclei can be inferred by interpreting measured data from direct reactions on proton such as elastic or inelastic scattering of proton (p,p') or one-nucleon transfer reaction (p,d). A series of experimental results has been obtained at the GANIL facilities on the setting composed of the MUST telescope array used for the detection of light charged-particles and of CATS beam detectors. This setting aims at measuring reactions on light proton or deuteron targets through reverse kinematics. Particularly, results on C{sup 10}, C{sup 11} and on direct reactions with the He{sup 8} beam of Spiral are presented. The first chapter is dedicated to the description of the most important theories concerning the nucleus. The experimental tools used to probe the nucleus are reported in the second chapter. The third and fourth chapters present the framework that has allowed us to analyse results from (p,p') and (p,d) reactions on weakly bound exotic nuclei. The last chapter is dedicated to the description of future experimental programs. (A.C.)

  4. Metabolic derivatives of alcohol and the molecular culprits of fibro-hepatocarcinogenesis: Allies or enemies?

    Chronic intake of alcohol undoubtedly overwhelms the structural and functional capacity of the liver by initiating complex pathological events characterized by steatosis, steatohepatitis, hepatic fibrosis and cirrhosis. Subsequently, these initial pathological events are sustained and ushered into a more complex and progressive liver disease, increasing the risk of fibro-hepatocarcinogenesis. These coordinated pathological events mainly result from buildup of toxic metabolic derivatives of alcohol including but not limited to acetaldehyde (AA), malondialdehyde (MDA), CYP2E1-generated reactive oxygen species, alcohol-induced gut-derived lipopolysaccharide, AA/MDA protein and DNA adducts. The metabolic derivatives of alcohol together with other comorbidity factors, including hepatitis B and C viral infections, dysregulated iron metabolism, abuse of antibiotics, schistosomiasis, toxic drug metabolites, autoimmune disease and other non-specific factors, have been shown to underlie liver diseases. In view of the multiple etiology of liver diseases, attempts to delineate the mechanism by which each etiological factor causes liver disease has always proved cumbersome if not impossible. In the case of alcoholic liver disease (ALD), it is even more cumbersome and complicated as a result of the many toxic metabolic derivatives of alcohol with their varying liver-specific toxicities. In spite of all these hurdles, researchers and experts in hepatology have strived to expand knowledge and scientific discourse, particularly on ALD and its associated complications through the medium of scientific research, reviews and commentaries. Nonetheless, the molecular mechanisms underpinning ALD, particularly those underlying toxic effects of metabolic derivatives of alcohol on parenchymal and non-parenchymal hepatic cells leading to increased risk of alcohol-induced fibro-hepatocarcinogenesis, are still incompletely elucidated. In this review, we examined published scientific findings on how alcohol and its metabolic derivatives mount cellular attack on each hepatic cell and the underlying molecular mechanisms leading to disruption of core hepatic homeostatic functions which probably set the stage for the initiation and progression of ALD to fibro-hepatocarcinogenesis. We also brought to sharp focus, the complex and integrative role of transforming growth factor beta/small mothers against decapentaplegic/plasminogen activator inhibitor-1 and the mitogen activated protein kinase signaling nexus as well as their cross-signaling with toll-like receptor-mediated gut-dependent signaling pathways implicated in ALD and fibro-hepatocarcinogenesis. Looking into the future, it is hoped that these deliberations may stimulate new research directions on this topic and shape not only therapeutic approaches but also models for studying ALD and fibro-hepatocarcinogenesis.

    The infraorder Furnariides is a diverse group of suboscine passerine birds comprising a substantial component of the Neotropical avifauna. The included species encompass a broad array of morphologies and behaviours, making them appealing for evolutionary studies, but the size of the group (ca. 600 species) has limited well-sampled higher-level phylogenetic studies. Using DNA sequence data from the nuclear RAG-1 and RAG-2 exons, we undertook a phylogenetic analysis of the Furnariides sampling 124 (more than 88%) of the genera. Basal relationships among family-level taxa differed depending on phylogenetic method, but all topologies had little nodal support, mirroring the results from earlier studies in which discerning relationships at the base of the radiation was also difficult. In contrast, branch support for family-rank taxa and for many relationships within those clades was generally high. Our results support the Melanopareidae and Grallariidae as distinct from the Rhinocryptidae and Formicariidae, respectively. Within the Furnariides our data contradict some recent phylogenetic hypotheses and suggest that further study is needed to resolve these discrepancies. Of the few genera represented by multiple species, several were not monophyletic, indicating that additional systematic work remains within furnariine families and must include dense taxon sampling. We use this study as a basis for proposing a new phylogenetic classification for the group and in the process erect new family-group names for clades having high branch support across methods. ?? 2009 The Willi Hennig Society.

    Full Text Available Human Anatomy and Physiology I and II are major gateway courses into nursing and other health related sciences careers.  Being a New York City community college, the students at Queensborough Community College are highly diverse not only in their ethnic and cultural background, but also in the levels of preparedness. When they take Human Anatomy-Physiology I as the first pre-requisite class, many are either freshman or returning students after a hiatus. Many students lack formal training in Science or Biology and are overwhelmed by the depth and immensity of the material presented in above courses. Though the enrollment for these classes is heavy; above factors lead to high attrition rates. However one common feature of this new generation of students is their access and familiarity to the internet, digital technology and other techno gadgets such as smart phones, tablets, etc. Though it is hard for us to accept, it is a fact that today’s generation of students (generation Y is more techno savvy and these gadgets engage (or distract them more than books. This indicated a clear need for developing alternatives to traditional teaching methods to engage students of an urban community college setting. We decided to investigate if a web-based supplemental tutorial would help engage these students and thus help them build their course knowledge base to improve their academic performance.

    We conducted 25 separate glove fabric permeation studies during this project. The permeations were carried out in the small (1 inch) glass ASTM cell. One other permeation study was carded out with a large (two inch) modified ASTM cell for comparison with the small cell results. We also compared the LLNL procedure from both large and small cells with the standard ASTM test procedure which uses a liquid solution on the breakthrough side of the fabric (the liquid is then sampled on a periodic basis). In all comparisons we observed a close-correlation in breakthrough times between the two procedures and the two cell sizes. In the course of this study, we tested ten different glove materials. These included neoprene (original ASTM round-robin sheet stock, 16 mil thickness), Edmont Sol-Vex (nitrile), Pioneer nitrile, Pioneer Pylox (polyvinyl chloride), North Viton (trademark for fluoroelastomers), North SilverShield (Norfoil, trademark for a flexible metallized laminate), Safety 4 4H (patented plastic laminate), and QRP PolyTuff (polyurethane) 20G-2000 (5 mil), 23G-2300 (1.5 mil), and 25G-2500 (1.5 mil). Three of the glove materials, Viton and Silver Shield (North), and 4H (Safety 4), did not allow any permeation measurable by our system to either 1,2-dichloroethane or 3% diphenylmercury (in 1,2-dichloroethane) for a period greater than six hours. A fourth material, QRP Poly Tuff 2OG-2000, did not allow any measurable penetration of Asilamine (an aromatic diamine) for a time pedod of greater than 4 hours. Breakthrough times and curves were obtained for all other tested materials. Eleven different chemicals were used to challenge the glove materials.

    Chirita D.Don,a large genus in the subfamily Cyrtandroideae of Gesneriaceae,has been the subject of much debate whether it is a natural group or not.In addition,the highly heterogeneous Chirita has also been very problematic with regard to delimitation and subdivision.Here we used the nrDNA internal transcribed spacer and cpDNA trnL-F for molecular phylogenetic analaysis,combined with morphological data.Our results suggest that Chirita is an artificial,polyphyletic genus.The most important character that defines Chirita,the dorso-ventrally oblique and bilamellar stigma,has evolved convergently in different clades of diandrous Cyrtandroideae.Chirita sensu stricto only includes the species of Chirita sect.Chirita,whereas Chirita sect.Microchirita is an independent clade located at the basal node of the phylogenetic tree.Chirita sect.Liebigia is closely related to Didymocarpus with an entire stigma unlike other species of Chirita.The species of Chirita sect.Gibbosaccus,Chiritopsis,Primulina,and Wentsaiboea form a monophyletic group that is sister to a strongly supported clade comprising four monotypic genera Paralagarosolen,Calcareoboea,Petrocodon,and Tengia.We further analyzed the morphological evolutionof Chirita and identified a series of morphological synapomorphies for the monophyletic groups revealed herein,and thereby provide a taxonomic treatment in this study.

    members. Conclusion: This analysis demonstrated that in all five partners state-of-the-art preventative mental healthcare was included in the last deployment in Afghanistan, including a positive approach towards strengthening the mental resilience, a focus on self-regulatory skills and self-empowerment, and several initiatives that were well-integrated in a military context. These initiatives were partly/completely implemented by the military/colleagues/supervisors and applicable during several phases of the deployment cycle. Important new developments in operational mental health support are recognition of the role of social leadership and enhancement of operational peer support. This requires awareness of mental problems that will contribute to reduction of the barriers to care in case of problems. Finally, comparing mental health support services across countries can contribute to optimal preparation for the challenges of military deployment.

    In a liberal democracy, policy decisions regarding ethical controversies, including those in research ethics, should incorporate the opinions of its citizens. Eliciting informed and well-considered ethical opinions can be challenging. The issues may not be widely familiar and they may involve complex scientific, legal, historical, and ethical dimensions. Traditional surveys risk eliciting superficial and uninformed opinions that may be of dubious quality for policy formation. We argue that the theory and practice of deliberative democracy (DD) is especially useful in overcoming such inadequacies. We explain DD theory and practice, discuss the rationale for using DD methods in research ethics, and illustrate in depth the use of a DD method for a longstanding research ethics controversy involving research based on surrogate consent. The potential pitfalls of DD and the means of minimizing them as well as future research directions are also discussed.

  16. CMApp: a Dynamic Presentation of the Clemmow-Mullaly-Allis Diagram for Cold Plasma Waves

    2015-11-01

    The CMA diagram contains a great deal of qualitative information about the character of cold-plasma waves and their evolution in spatially varying magnetic fields and electron density. We create a dynamic version of the CMA diagram which we call CMApp, in which the user can navigate the CMA diagram and arbitrarily zoom into chosen regions. The user chooses the form of the variables and many other aspects of the generalized diagram, including whether wave-normal surfaces or inverse-wave-normal surfaces are plotted. Since the zoom level is dynamic, there is no need to use logarithmic axes, an unrealistic ion-to-electron mass ratio, or to normalize magnetic field and density to wave frequency, thus enabling the diagram to be more of a quantitative tool. Examples of the applications of CMApp to wave propagation in different parameter regimes are illustrated.

    International Nuclear Information System (INIS)

    Perception level and social position of radiological technologist influence satisfaction level of their job. This study aims to use foundational data to improve perception level and social position of radiological technologists. We conducted interviews and a fill-out survey with 233 students who have been majoring in health-related fields at five universities and colleges located in Busan and who finished internship programs. The study analyzed 233 answer sheets excluding 17 inadequate answer sheets using T-test, ANOVA and multiple regression analysis with SAS9.1. The mean score of perception level was 3.33±0.56. The personal image of radiological technologist showed the best score(3.43±0.56) whereas the social image showed the worst(3.12±0.79). According to the classification of the subject, the answer, 'radiological technologist is specialized job', showed the best score(3.99±0.79). The answer 'radiological technologist suffered from less stress and workload than others when they work usually' showed the worst score(2.88±0.98). According to the classification of each health-related major, the mean score of students who are a major in the department of the radiological technologist was the best(3.46±0.46) and the students who are major in department of the physical therapy was the worst(3.24±0.40). The radiological technologist have to effort to make positive image in the hospital. It is possible to be developed their knowledge and professionalism by cooperating between school and hospital as well as advertising with mass madia.

  18. Dealing with opponents of industry: Let the allies work for you

    International Nuclear Information System (INIS)

    Full text: The opponents of industry, and most Green campaigning groups, thrive on controversy. Opponents of industry, and of the nuclear industry in particular, can expect to find a more receptive public audience than do the companies they attack. Therefore, there is little to be gained by industry entering into direct conflict, or even high-profile debate, with opponents. Industry spokesmen do not rate as being trustworthy in the eyes of the public. And it does not pay to directly attack the credibility, however justified such criticisms are, of the likes of Greenpeace. In a polarised debate, if your company is seen to be partisan and the opponents to be neutral, the public will gravitate towards the opponents. The way forward is to influence the forces which ran help industry establish the middle ground to dissipate the tension. The problem for industry is not so much that it has opponents, but that it does not have enough third party advocates to mediate in disputes. Therefore, the first step is to identify the key issues facing a company or industry. The second, is to work with credible people and organisations to establish independent mechanisms which can prevent an unfavourable climate building up around those issues. The art of dealing with opponents, is the art of identifying such mechanisms (people, organisations and professions) to influence an increasingly cynical and distrusting public. These opinion-formers should be the main focus of a communications strategy designed to counter opponents. They are the conduit through which to influence public opinion in general. For instance, the debate surrounding the incidence of leukaemia around nuclear sites cannot be answered by the industry using the facts, scientific evidence, or by entering into a noisy dialogue with opponents. However, the medical profession, along with scientists working outside the nuclear industry, is in a position to shift public concern away from nuclear sites. BNFL has promoted research into leukaemia by independent bodies. The results of this work discredited the view that sites such as Sellafield were responsible for the so-called leukaemia clusters. This has resulted in the debate becoming less polarised. The media is not so interested in the issue. This issue no longer offers fertile ground for opponents and its impact is much reduced. When there is a whole community of third party advocates which can explain an issue in its broader context, a company or industry can take a low-profile. No news can often be good news. In today's society the values people hold cannot be ignored. To continue in business, industry has to be acceptable to society. Otherwise politicians, thinking short-term about their popularity, will become hostile to any particular activity an industry might launch. The lesson of the Brent Spar oil platform must not be forgotten. The world's largest company, with all the facts, scientific evidence and resources at its disposal, lost the battle to dump the platform at sea. It was beaten by bad science, lies and emotion, in a polarised debate. Most European governments opposed Shell because their publics did: some with bombs. The lesson is that the public likes to feel in control of developments, progress and industry. It does not trust industry. If an industry or company does not have an effective screen of third party advocates to answer public concerns, the opponents will win the day. The public will listen to the more credible voices in society, such as, academic institutions, the medical profession, representative bodies, the media and the like. If the public feels that it has been consulted and that the issue is 'under control' there will be little ground for polarisation. The scare tactics of extreme opponents will not work. In the modern world, when peoples lives are often out of control, people need to be reassured that society is managing issues, industry and development. That reassurance must come from holding a dialogue. It is impossible for the public to love industry; it is not necessary, and perhaps it is not

  19. ARF: a versatile DNA damage response ally at the crossroads of development and tumorigenesis

    Directory of Open Access Journals (Sweden)

    Athanassios eKotsinas

    2014-07-01

    Full Text Available ARF is a tumor suppressor protein that senses oncogenic and other stressogenic signals. It can trigger p53-dependent and -independent responses with cell cycle arrest and apoptosis induction being the most prominent ones. Other ARF activities, particularly p53-independent ones, that could help in understanding cancer development and provide potential therapeutic exploitation are underrated. Although ARF is generally not expressed in normal tissues, it is essential for ocular and male germ cells development. The underlying mechanism(s in these processes, while not clearly defined, point towards a functional link between ARF, DNA damage and angiogenesis. Based on a recent study from our group demonstrating a functional interplay between ATM and ARF during carcinogenesis, we discuss the role of ARF at the crossroads of cancer and developmental processes.

  2. With no way out and with no allies: Riots in French "banlieues"

    Directory of Open Access Journals (Sweden)

    Filipović Mirko

    2006-01-01

    Full Text Available Riots in French "banlieues" can be properly understood only within a context of the French economic and social history in the last few decades. "Trente glorieuses", the increase of the immigrant population, French "welfare state" and urban politics, the effects of the economic crisis of the 70`s, dismantling and marginalization of the working class environment, concentration of the unemployment and poverty in the "banlieues", segregation and ghettoization - these are the necessary elements of any sociological interpretation of the actual crisis. Between the "urban poverty" and the riots, several mediations have also an important impact: new security policy and police violence - the evolution of Welfare state towards the Penal state, new forms of racism and social exclusions, inefficiency of the "Republican model of integration", suburban youth sub-culture as an attempt of neutralizing the growing stigma etc. Persistent treating of a segment of citizenry as suspect, intrinsically prone to violence - as potential enemies, could prove to be, in the future, a self-fulfilling prophecy.

  4. Uneasy allies: pro-choice physicians, feminist health activists and the struggle for abortion rights.

    Science.gov (United States)

    Joffe, C E; Weitz, T A; Stacey, C L

    2004-09-01

    Abortion represents a particularly interesting subject for a social movements analysis of healthcare issues because of the involvement of both feminist pro-choice activists and a segment of the medical profession. Although both groups have long shared the same general goal of legal abortion, the alliance has over time been an uneasy one, and in many ways a contradictory one. This paper traces points of convergence as well as points of contention between the two groups, specifically: highlighting the tensions between the feminist view of abortion as a women-centred service, with a limited, 'technical' role for the physicians, and the abortion-providing physicians' logic of further medicalization/professional upgrading of abortion services as a response to the longstanding marginality and stigmatisation of abortion providers. Only by noting the evolving relationships between these two crucial sets of actors can one fully understand the contemporary abortion rights movement. We conclude by speculating about similar patterns in medical/lay relationships in other health social movements where 'dissident doctors' and lay activists are similarly seeking recognition for medical services that are controversial.

    The clinical skills remain crucial for effective patient care in today’s medical environment. Research works have shown that students lack clinical skills even after graduation. One reason which could be the cause is that the faculty is unable to evaluate the students on the clinical skills exam, if the student is informed about the significance of clinical skills and about a certification exam structure which not only evaluates the student on a theory exam section but also on a clinical skil...

  8. With the help of a foreign ally: biopharmaceutical innovation in India after TRIPS.

    Science.gov (United States)

    Angeli, Federica

    2014-05-01

    This article investigates the implications of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), which reached full-fledged implementation in 2005, for the patenting activity of Indian biopharmaceutical companies. The Indian biopharmaceutical industry is well-known for its generic producers, whose business models capitalize on the opportunity to reverse-engineer patented compounds and produce them at low costs through process innovation. By strengthening intellectual property rights, TRIPS determined a major regulative change, which presents the characteristics of an institutional shock. The examination of the patenting and alliance activity of 123 Indian biopharmaceutical firms between 1999 and 2009 reveals two important insights. First, the innovation outcome of Indian biopharmaceuticals has sharply increased during the transition to TRIPS-compliant regulation, suggesting that Indian companies have been capable and willing to transit from an imitation-based to an innovation-based business model. Second, those biopharmaceutical firms holding cross-border alliances to foreign partners have proved significantly more successful at enhancing their innovative capability. This research delivers a multifold contribution to the policy debate surrounding the enforcement of TRIPS in emerging economies. First, it suggests that such regulatory change may have encouraged biopharmaceutical innovation in India, despite the sceptical voices who did not foresee any benefits because of inherent inertia of the industry. Second, by arguing and testing the advantages of foreign partnerships, this research highlights that the much feared return of pharmaceutical foreign companies to India could instead favour adaptation to institutional change. Implications for Indian public health are particularly critical. The impact of TRIPS on drug pricing and on the capability--and willingness--of Indian biopharmaceuticals to invest in local health conditions are two crucial points of discussion. PMID:23558959

  15. Enhancing engineering practices for productivity and profits in agro-allied industries

    International Nuclear Information System (INIS)

    The word productivity is a part of everyday vocabulary of industrial engineers and managers. Terms such as optimum utilization of resources, operational efficiency, product competitiveness, maintenance culture, etc., are mentioned with regular frequency. This is healthy, because productivity improvement does not happen by wishing for it or trying harder but by deliberately planning for it. The rewards of higher productivity are immense. At the firm level, such benefit include high production rates, higher profits, better quality products and services, customer satisfaction, higher take home pay for employees and high employee morale. Many of these benefits can be derived through the application of simple potential productivity improvement tools that are hinged on engineering practices

    2004-01-01

    The nucleation of ordered phase was simulated based on microscopic diffusion equation and the assumptions of the classical nucleation theory were examined. The quantitative calculations of interface thickness evolution were accomplished for the first time. It was found that the interfaces between ordered phase and disordered matrix were diffuse. The interface thickness decreased with time, from the initial 1.2 nm to an equilibrium value 0.6 nm. The ratios of the radius of ordered particles and the interface thickness monotonously increased, but they were of the same order of magnitude all the time. The sharp interface assumption should not be adopted in this stage. For the Al-10%Li (atom fraction) alloy aged at 192℃, the assumptions of the classical nucleation theory disagreed with the facts. The phase transformation followed the non-classical nucleation mechanism and the applicable scope of the classical nucleation should be confined.

  18. A Review of the Flammability Factors of Kenaf and Allied Fibre Reinforced Polymer Composites

    Directory of Open Access Journals (Sweden)

    C. H. Lee

    2014-01-01

    Full Text Available Natural fibre is a well-known reinforcement fibre in polymer-matrix Composites (PMC lately. Natural fibre has fast growing and abundance properties which make it available at very low cost. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it. In this paper, fire flammability is the main concern for natural fibre reinforced polymer (NFRP composites especially kenaf fibre. To estimate its flammability, a wide range of factors can be considered such as fibre content, type of matrices, pH conditions, treatment, and fire retardant (FR filler’s type. The most important criteria are the ignition time, rate of propagation, and fire behavior. thermogravimetric analysis (TGA, different scanning calorimetric (DSC, and dynamic mechanical analysis (DMA are the three most famous methods used to investigate the fire behaviour of composites.

    2014-01-01

    DNA barcoding can be an effective tool for fast and accurate species-level identification based on sequencing of the mitochondrial cytochrome c oxidase subunit (COI) gene. The diversity of this fragment can be used to estimate the richness of the respective species. In this study, we explored the use of DNA barcoding in a group of ornamental freshwater fish of the genus Hyphessobrycon. We sequenced the COI from 10 species of Hyphessobrycon belonging to the "Rosy Tetra Clade" collected from the Amazon and Negro River basins and combined our results with published data. The average conspecific and congeneric Kimura 2-parameter distances were 2.3% and 19.3%, respectively. Six of the 10 species were easily distinguishable by DNA barcoding (H. bentosi, H. copelandi, H. eques, H. epicharis, H. pulchrippinis, and H. sweglesi), whereas the remaining species (H. erythrostigma, H. pyrrhonotus, H. rosaceus and H. socolofi) lacked reciprocal monophyly. Although the COI gene was not fully diagnostic, the discovery of distinct evolutionary units in certain Hyphessobrycon species under the same specific epithet as well as haplotype sharing between different species suggest that DNA barcoding is useful for species identification in this speciose genus.

    2015-01-01

    Full Text Available Sphaerodoridae is a group of benthic marine worms (Annelida characterized by the presence of spherical tubercles covering their whole surface. They are commonly considered as belonging to Phyllodocida although sistergroup relationships are still far from being understood. Primary homology assessment of their morphological features are lacking, hindering the appraisal of evolutionary relationships between taxa. Therefore, our detailed morphological investigation focuses on different Sphaerodoridae as well as on other members of Phyllodocida using an integrative approach combining scanning electron microscopy (SEM as well as immunohistochemistry with standard neuronal (anti-5-HT and muscular (phalloidin-rhodamine markers and subsequent CLSM analysis of whole mounts and sections. Furthermore, we provide histological (HES and light microscopical data to shed light on the structures and hypothetical function of sphaerodorid key morphological features. We provide fundamental details into the sphaerodorid morphology supporting a Phyllodocida ancestry of these enigmatic worms. However, the muscular arrangement and the presence of an axial muscular pharynx is similar to conditions observed in other members of the Errantia too. Furthermore, nervous system and muscle staining as well as SEM and histological observations of different types of tubercles indicate a homology of the so called microtubercles, present in the long-bodied sphaerodorids, to the dorsal cirri of other Errantia. The macrotubercles seem to represent a sphaerodorid autapomorphy based on our investigations. Therefore, our results allow comparisons concerning morphological patterns between Sphaerodoridae and other Phyllodocida and constitute a starting point for further comparative investigations to reveal the evolution of the remarkable Sphaerodoridae.

    2015-07-01

    Since the discovery of leptin in 1994, our vision of adipose tissue as a static organ regulating mainly lipid storage and release has been completely overthrown, and adipose tissue is now seen as an active and integral organ in human physiology. In the past years, extensive research has tremendously given us more insights in the mechanisms and pathways involved not only in normal but also in 'sick' adipose tissue, for example, in obesity and lipodystrophy. With growing evidence of a link between obesity and several types of cancer, research focusing on the interaction between adipose tissue and cancer has begun to unravel the interesting but complex multi-lateral communication between the different players. With breast cancer as one of the first cancer types where a positive correlation between obesity and breast cancer incidence and prognosis in post-menopausal women was found, we have focused this review on the paracrine and endocrine role of adipose tissue in breast cancer initiation and progression. As important inter-species differences in adipose tissue occur, we mainly selected human adipose tissue- and breast cancer-based studies with a short reflection on therapeutic possibilities. This review is part of the special issue on "Adiposopathy in Cancer and (Cardio)Metabolic Diseases".

  6. Ultrasonic measurements and other allied parameters of yttrium soaps in mixed organic solvents

    International Nuclear Information System (INIS)

    The ultrasonic measurements of yttrium soaps were made in a mixture of 70 % benzene and 30 % dimethylsulfoxide (ν/ν) to determine the critical micelle concentration, soap-solvent interaction and various acoustic and thermodynamic parameters. The values of the CMC decrease with increasing chainlength of fatty acid constituent of the soap molecule and are in agreement with the values obtained from other micellar properties. The various acoustic parameters (intermolecular freelength, adiabatic compressibility, apparent molar compressibility, specific acoustic impedance, apparent molar volume, molar sound velocity, solvation number, available volume and relative association) for yttrium soaps (myristate, palmitate, stearate and oleate) have been evaluated by ultrasonic velocity measurements.

  7. Oxytocin-Motivated Ally Selection is Moderated by Fetal Testosterone Exposure and Empathic Concern

    Directory of Open Access Journals (Sweden)

    Mariska Esther Kret

    2013-01-01

    Full Text Available In humans, the hypothalamic neuropeptide oxytocin shifts the individual’s focus on self-interest towards group-serving cognitions and decision making. Here we examine this general tendency in the context of group formation, where individuals included into their group (or not 18 targets morphed as having low or high-threat potential (with high-threat targets being beneficial to group-interests but potentially hurting the recruiter’s self-interest. Ninety healthy males self-administered oxytocin or placebo in a randomized double-blind, placebo-controlled study design, had their hands scanned to derive fetal testosterone vs. estradiol exposure from their 2D:4D ratio, and self-reported on their chronic empathic concern. Multilevel regression models revealed that when given oxytocin rather than placebo, individuals with low fetal testosterone priming included low-threat targets more and high-threat targets (somewhat less. Individuals with high fetal testosterone (i.e., low estradiol exposure, however, included high-threat targets more, and low-threat targets less when given oxytocin rather than placebo. Second, when given oxytocin rather than placebo, individuals with low empathic concern included low-threat targets more and high-threat targets less. Individuals with high empathic concern, however, included high-threat targets more, and low-threat targets less when given oxytocin rather than placebo. We conclude that oxytocin shifts the individual’s focus from self to group-serving cognition and decision making, and that these tendencies are stronger for males with high rather than low fetal testosterone exposure, and high rather than low empathic concern. Implications and avenues for future research are discussed.

    the electronic signals behaviour in an ever-changing construction site. Measurements of the signal strengths during excavation and concrete work are presented and compared with theoretical calculations used to predict wave propagation. The results show how present models overestimate signal attenuation patterns on the construction site. This is important for designing a reliable and secure wireless site networks to link BIM to the work-front.

    Spawning behaviour of Alosa alosa was observed by high resolution imaging sonar. Detected clouds of sexual products and micro bubbles served as a potential indicator of spawning activity. Peak spawning time was between 0130 and 0200 hours at night. Increasing detections over three consecutive nights were consistent with sounds of mating events (bulls) assessed in hearing surveys in parallel to the hydro acoustic detection. In 70% of the analysed mating events there were no additional A. alosa joining the event whilst 70% of the mating events showed one or two A. alosa leaving the cloud. In 31% of the analysed mating events, however, three or more A. alosa were leaving the clouds, indicating that matings are not restricted to a pair. Imaging sonar is suitable for monitoring spawning activity and behaviour of anadromous clupeids in their spawning habitats.

    There has been an exponential increase in the performance of silicon based semiconductor devices in the past few decades. This improvement has mainly been due to dimensional scaling of the MOSFET. However, physical constraints limit the continued growth in device performance. To overcome this problem, novel channel materials are being developed to enhance carrier mobility and hence increase device performance. This work explores a novel semiconducting alloy - Silicon-tin (SiSn) as a channel material for CMOS applications. For the first time ever, MOS devices using SiSn as channel material have been demonstrated. A low cost, scalable and manufacturable process for obtaining SiSn by diffusion of Sn into silicon has also been explored. The channel material thus obtained is electrically characterized by fabricating MOSCAPs and Mesa-shaped MOSFETs. The SiSn devices have been compared to similar devices fabricated using silicon as channel material.

    African Americans make up an increasing proportion of persons with the acquired immunodeficiency syndrome (AIDS). I identify and describe cultural elements such as oral traditions, multiple naming, a collective identity, extended families, and sexuality influenced by myth and exaggeration that condition African Americans' reactions to AIDS prevention. I also offer suggestions on how these cultural elements can be used for effective AIDS prevention efforts in African-American communities.

    Full Text Available Students in an undergraduate microbiology course for health professions majors perform a shadowing-based learning exercise for their course project. Students accomplish this by shadowing a health care professional of their choice, specifically incorporating basic microbiological concept themes into their observations. These concept themes include the biological nature, health effects, detection, and control of microorganisms. Upon completion of the shadowing experience, students present a concise report, which is graded on how well the students connect course scientific concepts with actual clinical practice.

    Full Text Available The study examines and compares the capital structure and efficiency of capital employed between listed and unlisted agro-based firms in Nigeria. Data collected from 88 agro-based firms using random sampling technique for the period 2005-2010 were analysed using Z-test, Capital Structure Ratio (CSR and Return on Capital Employed Ratio (ROCE analysis as well as descriptive statistics. The result revealed significant differences between the capital structure of listed and listed agro-based firms. Listed agro-based firms recorded the highest debt to equity ratio than their unlisted counterpart. Short term debts also constituted a greater percentage of the total debt ratios of both sample groups. Unlisted agro firms were more efficient than listed firms in terms of return on capital employed. Accordingly, series of recommendations have also been offered.

    Full Text Available Platelets are crucial effector cells in hemostasis. In addition, platelets are increasingly recognized as major inflammatory cells with key roles in innate and adaptive immune responses. Activated platelets have key thromboinflammatory activities linking coagulation to inflammatory response in a variety of coagulation disorders and vasculopathies. Recently identified inflammatory activities of platelets include the synthesis of IL-1β from spliced pre-RNA, as well as the presence and assembly of inflammasome which intermediate IL-1β secretion. Here we review the mechanisms by which platelets activate translation machinery and inflammasome assembly to synthesize and release IL-1β. The contributions of these processes to protective and pathogenic responses during infectious and inflammatory diseases are discussed.
