Comparison of the Automated Oscillometric Method With the Gold Standard Doppler Ultrasound Method to Access the Ankle-Brachial Pressure Index

Objective: Despite its screening interest, the ankle-brachial pressure index (ABPI) remains uncommon in general practice, because it needs training and specific devices as Doppler. Easier methods such as the use of automated oscillometric devices may facilitate the peripheral arterial diseases (PADs) screening. We wanted to assess the reliability of the automated oscillometric measurement of the ABPI, compared with the gold standard Doppler ultrasound measurement. Patients and Method: In 287 patients aged 65 years or older without diagnosed PAD, we performed ABPI measurements with oscillometric and Doppler devices. Reproducibility was assessed by the intraclass correlation coefficient of agreement (R) and the Bland and Altman method. Results: The intermethod reliability was bad (R = .346, 95% CI = (0.268-0.420)), with a large confidence interval of the individual differences between the 2 methods: 95% CI = (—0.183-0.346). Conclusion: Automatic oscillometric devices cannot be recommended as reliable methods for ABPI measurement

KPP reaction-diffusion equations with a non-linear loss inside a cylinder

We consider in this paper a reaction-diffusion system in presence of a flow and under a KPP hypothesis. While the case of a single-equation has been extensively studied since the pioneering Kolmogorov-Petrovski-Piskunov paper, the study of the corresponding system with a Lewis number not equal to 1 is still quite open. Here, we will prove some results about the existence of travelling fronts and generalized travelling fronts solutions of such a system with the presence of a non-linear spacedependent loss term inside the domain. In particular, we will point out the existence of a minimal speed, above which any real value is an admissible speed. We will also give some spreading results for initial conditions decaying exponentially at infinity

Symmetric functions, tableaux decompositions and the Fermion-Boson correspondence

An extended Fermion-Boson correspondence is introduced for skew Schur functions. Certain members of a general class of recently-developed determinantal forms, based on outer strip decompositions of skew shape tableaux, are described in this context. Un analogue pour des fonctions de Schur gauche du correspondence Fermion-Boson est introduit. Á ce propos, nous decrivons certaines membres d'une nouvelle famille de determinants produit par des decompositions du tableau

Phase separation in hydrogen-helium mixtures at Mbar pressures

The properties of hydrogen-helium mixtures at Mbar pressures and intermediate temperatures (4000 to 10000 K) are calculated with first-principles molecular dynamics simulations. We determine the equation of state as a function of density, temperature, and composition and, using thermodynamic integration, we estimate the Gibbs free energy of mixing, thereby determining the temperature, at a given pressure, when helium becomes insoluble in dense metallic hydrogen. These results are directly relevant to models of the interior structure and evolution of Jovian planets. We find that the temperatures for the demixing of helium and hydrogen are sufficiently high to cross the planetary adiabat of Saturn at pressures around 5 Mbar; helium is partially miscible throughout a significant portion of the interior of Saturn, and to a lesser extent in Jupiter.Comment: 6 pages, 7 figures.

Panel Discussion - Management of Eurasian watermilfoil in the United States using native insects: State regulatory and management issues

While researchers have evaluated the potential of native insect herbivores to manage nonindigenous aquatic plant species such as Eurasian watermilfoil ( Myriophyllum spicatum L.), the practical matters of regulatory compliance and implementation have been neglected. A panel of aquatic nuisance species program managers from three state natural resource management agencies (Minnesota, Vermont and Washington) discussed their regulatory and policy concerns. In addition, one ecological consultant attempting to market one of the native insects to manage Eurasian watermilfoil added his perspective on the special challenges of distributing a native biological control agent for management of Eurasian watermilfoil

Hubungan Gaya Kepemimpinan Kepala Ruangan Dengan Tingkat Stres Kerja Perawat Di Ruang Rawat Inap RSUD Bitung

Abstrack : Leadership style is the way in which a leader in directing and influencing others to have the motivation to achieve goals. Consists of three kinds, namely autocratic leadership style, democratic, and laissez-faire. Work stress is a human reaction to an external stimulus which is considered as a threat. The purpose of this study to determine the relationship of leadership style of head room with the stres level of nurses working in general hospital area Bitung. This research is a descriptive analytic design cross sectional study. The sampling technique used is totally till where the entire population were sampled as many as 53 people. Data analysis using chi-square test wit significance level α = 0,05. The result showed that leadership style room has a relationship with stress level of nurses in general hospital area Bitung with value p = 0,009 < α = 0,05, which means that Ho is rejected. The conclusion of this study that there is a relationship between leadership style room with a stress level of nurses in a general hospital area Bitung. The advice in this study is expected to be given training nurse-specific training to address specific problems in nursing stress especially in the working nurse

Metaplectic Ice

Spherical Whittaker functions on the metaplectic n-fold cover of GL(r+1) over a nonarchimedean local field containing n distinct n-th roots of unity may be expressed as the partition functions of statistical mechanical systems that are variants of the six-vertex model. If n=1 then in view of the Casselman-Shalika formula this fact is related to Tokuyama's deformation of the Weyl character formula. It is shown that various properties of these Whittaker functions may be expressed in terms of the commutativity of row transfer matrices for the system. Potentially these properties (which are already proved by other methods, but very nontrivial) are amenable to proof by the Yang-Baxter equation

Pengaruh Penyuluhan Kesehatan Tentang Hiv-aids Terhadap Stigma Masyarakat Di Desa Watumea Kecamatan Eris Kabupaten Minahasa

Abstact Stigma is the act of providing a social label that aims to separate or discredit a person or group of people with a stamp or a bad view. Many factors influence the emergence of stigma in society, one of the most influencing factors is the lack of knowledge of a person about a disease. For that we need to do health education in the form of health education to increase public knowledge. The purpose of this study was to analyze the influence of health education on HIV-AIDS on community stigma in Watumea Village, Eris Sub-District, Minahasa District. The research method is using pre experimental design using one group pre-post test design approach. Sampling technique in this research Random Sampling. Data collection was done by using questionnaire. Data processing using computer program with wilcoxon signed rank test with significance level 95% (α =0,005). The result of the research by using wilcoxon signed rank analysis showed significant influence of health education to society stigma (p = 0,000). Conclusion There is influence of health education about HIV-AIDS to society stigma in Watumea Village, District of Eris Minahasa Regency. Suggestions for the Community to actively seek information about HIV-AIDS especially the factors of spread and overcome them
