Eccentric fixation measurements using visuoscopy and Macula Integrity Tester (MIT) in children with amblyopia

2021

The aim of the work was to compare measurements of eccentric fixation in children with amblyopia using two different methods, a traditional visuoscopy and MIT. Monocular fixation was evaluated using visuoscopy and MIT in 16 patients (from 5 to 9 years old). Measurements were started with the better seeing eye to compare the results obtained with the amblyopic eye. All study participants were selected with anisometropic and refractive amblyopia. Visuoscopy is simpler than MIT and less dependent on patient responses, so visioscopy can be used for young children who have not yet acquired verbal skills. Children over the age of 5 can more easily understand the MIT method and get more reliable r…

Effets d'une complémentation nutritionnelle en vitamines et minéraux sur la chute de force et les marqueurs biologiques consécutifs à un exercice exc…

Purpose. – The effects of vitamins and minerals complex supplementation on maximal voluntary contraction decrease (FMV) and biological markers following an eccentric exercise at old people. Method. – Sixteen elderly subjects took either placebo (Pl group) or vitamins and minerals (Isoxan Senior, NHS, Rungis, France) (group S) for 21 d before an eccentric exercise and for 3 d after the exercise. The FMV and surface EMG activity (RMS) of the vastus lateralis (VL), vastus medialis (VM) and rectus femoris (RF) were recorded before (Pre), immediately after (Post), 24 h (Post 24) and 48 h (Post 48) after the exercise. CCVThe creatine kinase (CK), lactate deshydrogenase, malondialdehyde, and tumor…

Effect of material and geometric parameters on natural convection heat transfer over an eccentric annular-finned tube

2019

In this work, the performance of an eccentric annular finned tube heat exchanger under natural convection conditions has been investigated numerically. The objective of the study is to analyse the ...

Geometric optimal control of elliptic Keplerian orbits

2005

This article deals with the transfer of a satellite between Keplerian orbits. We study the controllability properties of the system and make a preliminary analysis of the time optimal control using the maximum principle. Second order sufficient conditions are also given. Finally, the time optimal trajectory to transfer the system from an initial low orbit with large eccentricity to a terminal geostationary orbit is obtained numerically.

Eccentricity in Mervyn Peake’s work

2013

International audience; Ce chapitre analyse l’un des motifs principaux de l’œuvre de Mervyn Peake: l’excentricité et ses modes d’expression textuelle et picturale dans Letters from a Lost Uncle (1948) et Figures of Speech (1954), au sein de l’intertexte formé par les biographies d’excentriques et le nonsense.

Altération des performances neuromusculaires après un exercice physique prolongé. Analyse comparée d'une épreuve de marathon et de triathlon

1998

The aim of this study was to compare the effects of a marathon and a triathlon on isometric and dynamic neuromuscular performances. Seven triathletes took part in 3 experimental situations : a 2 h 15 mn triathlon (TRI) (30 min swimming, 60 min cycling and 45 min running), a 2 h 15 mn marathon (MA) and a 45 min isolated run done at triathlon speed. The results showed a reduction of the isometric endurance time for knee extensor muscles (35 % of maximal voluntary contraction) after TRI (41 ± 24 %) and after MA (59 ± 19 %). The height of rise of the center of gravity of the counter-movement jumps (CMJ) was also significantly lower after MA (-12 ± 1 cm) than after TRI (-2,5 0,5 cm). Kinetic ana…

Eccentric Women? Gender and the Notion of Eccentricity

2012

British writers in the eighteenth century spent much time reflecting on the notion of normality, as the rising middle ranks promoted their ideology as a class, while defending the right of the individuals to their own personal choices. The period was also marked by scientific advances, and for this reason, it is not surprising that the term 'eccentric', originally restricted to astronomy, started to be used widely to refer to unconventional human behaviour. At first sight, eccentricity in the eighteenth century seems to be a male preserve, as the term is mostly applied to men famous for their wit and original thinking, such as Samuel Johnson or Lawrence Sterne. From this point of view, wome…

Sakarība starp acs iekšējo spiedienu un redzes nerva diska parametriem

2017

Maģistra darbs uzrakstīts uz 43 lappusēm. Darbs satur 25 attēlus un atsauces uz 41 literatūras avotu. Darba mērķis bija novērtēt acs iekšējā spiediena saistību ar redzes nerva ekskavācijas eksentricitāti cilvēkiem, kuriem nav konstatēta glaukoma. Pētījumā tika veikts Itālijā un tika analizētas 100 cilvēku acis. Pētījuma dalībnieku vecums bija no 25 līdz 45 gadiem, no kuriem 41 bija sieviete un 59 vīrieši. Tika novērtēts acs iekšējais spiediens, ņemot vērā radzenes pahimetrijas datus un tika iegūtas ar fundus kameru redzes nervu fotogrāfijas. Darbā tiek secināts, ka veselām acīm nepastāv korelācija starp acs iekšējo spiedienu un ekskavācijas lielumu, kā arī nepastāv korelācija starp vecumu. …

Muscular Strength Imbalances Are not Associated with Skin Temperature Asymmetries in Soccer Players

2020

Although strength imbalances using isokinetic dynamometer have been examined for injury risk screening in soccer players, it is very expensive and time-consuming, making the evaluation of new methods appealing. The aim of the study was to analyze the agreement between muscular strength imbalances and skin temperature bilateral asymmetries as well as skin temperature differences in the hamstrings and quadriceps. The skin temperature of the anterior and posterior thigh of 59 healthy male soccer athletes was assessed at baseline using infrared thermography for the identification of hamstrings-quadriceps skin temperature differences and thermal asymmetries (&gt
