Spontaneous walking characteristics of patients with peripheral arterial disease.

Walking rehabilitation is the cornerstone of patients with peripheral arterial disease (PAD) treatment. In order to propose a personalised walking rehabilitation program to each patient, it is important to know the PAD-patients walking characteristics. Such data are lacking in the literature.

[Systematic analysis of evaluations of Objective Structured Clinical Exam (OSCE) multiple circuits: Explanatory variables and inter-rater correlations].

Introduction: Objective Structured Clinical Examinations (OSCEs) assess professional performance in a simulated environment. Following their integration into the reform of the 2nd cycle of medical studies (R2C), this pedagogical modality was implemented in France. This study investigates the variability of students' OSCE scores, as well as their inter-rater reproducibility.

Powder flow from an intermediate bulk container - Discharge predictions and experimental evaluation.

Powders are usually dispensed, blended, and transferred between different manufacturing steps in so-called Intermediate Bulk Containers (IBCs), and discharge from an IBC plays a critical role in the ability to manufacture high-quality tablets. To better understand IBC discharge, the flow behavior of selected excipients was comprehensively characterized using a number of techniques including the Hausner ratio/Carr's index, Erweka flow test, FlowPro flow test, shear test and wall friction test as well as FT4 powder rheometer experiments. Jenike's hopper design methodology was then used to predict the minimum non-arching outlet diameter and the mode of flow.

Comparison of the Use of Arterial Doppler Waveform Classifications in Clinical Routine to Describe Lower Limb Flow.

Background: Characterisation of arterial Doppler waveforms is a persistent problem and a source of confusion in clinical practice. Classifications have been proposed to address the problem but their efficacy in clinical practice is unknown. The aim of the present study was to compare the efficacy of the categorisation rate of Descotes and Cathignol, Spronk et al.

Quantification of surface composition and surface structure of inhalation powders using TOF-SIMS.

A multivariate TOF-SIMS methodology has been developed and applied to quantify surface composition and chemical distribution for dry powder blends. Surface properties are often critical to the behavior of powder formulations, especially in the case of dry powders for inhalation, as surface properties directly affect inter-particulate forces and, hence, the dispersibility of the formulation. The mass spectrum at each pixel was fit to a linear combination of reference spectra obtained by non-negatively constrained alternating least squares.
