Ergonomic factors that cause the presence of pain muscle in students of dentistry
2009
Objective: To identify the ergonomic factors and the presence of muscular pain in dental students of VIII, IX, X semesters presently practicing at the clinics of the College of Dentistry of university of Cartagena, Colombia, South America. Materials and methods: This is a descriptive study carried out in dental students of the VIII, IX, and X semesters which were undergoing clinical practice at the College of Dentistry of University of Cartagena. A convenience sample of 83 students who met the inclusion criteria was taken and those who agreed to participate signed an informed consent. Data collection was obtained by means of a structured questionnaire for ergonomic factors and the presence …
Physiotherapy Students’ Experiences about Ethical Situations Encountered in Clinical Practices
2021
(1) Background: It is important to explore the ethical situations that physiotherapy students encountered in their clinical practices. (2) Methods: Qualitative, explorative, descriptive study. The participants included third-year physiotherapy students. They had to write five narratives about ethical situations encountered in their clinical practices. Krippendorff's method for qualitative content analysis was used to cluster units within the data to identify emergent themes. The study protocol was approved by the authors' University Ethic Committee of Human Research (H1515588244257). (3) Result: 280 narratives were reported by 64 students (23.34 ± 4.20 years, 59% women). Eight categories we…
Smoking Status and Severity of Ischemic Stroke. A Population-Based Study
2013
We aimed to investigate the impact of smoking status on clinical severity in patients with ischemic stroke event (IS). Patients were prospectively identified among residents of the city of Dijon, France (ca. 151,000 inhabitants), using a population-based registry, between 2006 and 2011. Demographic and clinical data were recorded. The initial clinical severity was quantified by the means of the National Institutes of Health Stroke Scale (NIHSS). Multivariable ordinal logistic regression was used to assess the effect of smoking status on severity. Among the 1,056 recorded patients with IS, data about smoking status were available for 973 (92.1%), of whom 658 (67.3%) were non-smokers, 187 (19…
Mitochondrial myopathy--a result of clofibrate/etofibrate treatment? Case report.
1985
A 66-year-old man had developed a myopathy while undergoing several periods of etofibrate and clofibrate therapy over the past 5 years. Discontinuation of etofibrate treatment failed to reverse his muscle illness which, however, did not progress. A muscle biopsy revealed a chronic myopathy marked by abundant, abnormally structured muscle mitochondria. His mitochondrial myopathy may represent a forme fruste of the Kearns-Sayre syndrome or other types of mitochondrial myopathy, clinically made evident by the etofibrate/clofibrate therapy, or a permanent, adverse side effect of clofibrate treatment. If the latter assumption proves to be correct, it will indicate that clofibrate therapy may ind…
Benefit of Targeting a LDL (Low-Density Lipoprotein) Cholesterol \textless70 mg/dL During 5 Years After Ischemic Stroke
2020
Background and Purpose— The TST trial (Treat Stroke to Target) evaluated the benefit of targeting a LDL (low-density lipoprotein) cholesterol of <70 mg/dL to reduce the risk of cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature or aortic arch plaque >4 mm, in a French and Korean population. The follow-up lasted a median of 5.3 years in French patients (similar to the median follow-up time in the SPARCL trial [Stroke Prevention by Aggressive Reduction in Cholesterol Level]) and 2.0 years in Korean patients. Exposure duration to statin is a well-known driver for cardiovascular risk reduction. We report here the TST results …
Robust Assembly Assistance Using Informed Tree Search with Markov Chains
2022
Manual work accounts for one of the largest workgroups in the European manufacturing sector, and improving the training capacity, quality, and speed brings significant competitive benefits to companies. In this context, this paper presents an informed tree search on top of a Markov chain that suggests possible next assembly steps as a key component of an innovative assembly training station for manual operations. The goal of the next step suggestions is to provide support to inexperienced workers or to assist experienced workers by providing choices for the next assembly step in an automated manner without the involvement of a human trainer on site. Data stemming from 179 experiment partici…
New behavioural trait adopted or rejected by observing heterospecific tutor fitness
2010
Animals can acquire behaviours from others, including heterospecifics, but should be discriminating in when and whom to copy. Successful individuals should be preferred as tutors, while adopting traits of poorly performing individuals should be actively avoided. Thus far it is unknown if such adaptive strategies are involved when individuals copy other species. Furthermore, rejection of traits based on tutor characteristics (negative bias) has not been shown in any non-human animal. Here we test whether a choice between two new, neutral behavioural alternatives—breeding-sites with alternative geometric symbols—is affected by observing the choice and fitness of a heterospecific tutor. A fiel…
Analysis of the electromagnetic radiation generated by a multipactor discharge occurring within a microwave passive component
2010
International audience; Multipactoring is a non-linear phenomenon that appears in highpower microwave equipments operating under vacuum conditions and causes several undesirable effects. In this manuscript, a theoretical and experimental study of the RF spectrum radiated by a multipactor discharge, occurring within a realistic microwave component based on rectangular waveguides, is reported. The electromagnetic coupling of a multipactor current to the fundamental propagative mode of a uniform waveguide has been analyzed in the context of the microwave network theory. The discharge produced under a single-carrier RF voltage regime has been approached as a shunt current source exciting such a…
Modeling and Experimental Verification of Ultrasound Transmission in Electro Insulation Oil
2012
A verification study of ultrasound transmission numerical simulation results with experiment results is presented in this paper. The work considers a model of a transformer tank which is filled with electro insulating oil. In the experiment, performed under laboratory conditions, an ultrasound wave is generated by a piezoelectric transducer that is fixed in the centre of the tank and measured by another transducer mounted inside the tank at three distances: 10, 20 and 30 cm from the sound source. The transducer is able to measure and generate acoustic waves in the ultrasound frequency band up to 1 MHz. The simulation considers numerical calculation of acoustic pressure distribution inside t…
A stochastic shape and orientation model for fibres with an application to carbon nanotubes
2012
Methods are introduced for analysing the shape and orientation of planar fibres from greyscale images of fibrous systems. The sequence of image processing techniques needed for segmentation of fibres is described. The identified fibres were interpreted as deformed line segments for which two shape and two orientation parameters are estimated by the maximum likelihood method. The methods introduced are shown to perform quite well for simulated systems of deformed line segments with known properties. They were applied to TEM images of carbon nanotubes embedded in polycarbonate.
