Strength and power changes of the human plantar flexors and knee extensors in response to resistance training in old age
2002
Aim: The aim of the present study was to assess and compare the improvements of muscle strength and power induced by a 16-week resistive programme in a population of 16 older men aged 65-81 years. Methods: Training was performed three times per week at an intensity of 80% of one repetition maximum (1RM) and consisted of both calf raise and leg press exercises. Before-, during- and after-training, maximum isometric and isokinetic torques, maximum power, 1RM, muscle cross-sectional area (CSA) and electromyographic activity (EMG) of the plantar flexors (PF) and knee extensors (KE) were examined. Results: For the KE and PF, respectively, training resulted in a 29.9 ± 4.4% (mean ± SE) and 21.6 ±…
Changes in electromyographic activity, muscle fibre and force production characteristics during heavy resistance/power strength training in middle-ag…
2001
The effects of a 6-month resistance training (2 day/week) designed to develop both strength and power on neural activation by electromyographic activity (EMG) of the agonist and antagonist knee extensors, muscle fibre proportion and areas of type I, IIa, and IIb of the vastus lateralis (VL) as well as maximal concentric one repetition maximum (1 RM) strength and maximal and explosive isometric strength of the knee extensors were examined. A total of 10 middle-aged men (M40; 42 +/- 2), 11 middle-aged women (W40; 39 +/- 3), 11 elderly men (M70; 72 +/- 3) and 10 elderly women (W70; 67 +/- 3) served as subjects. Maximal and explosive strength values remained unaltered during a 1-month control p…
Repetition without Repetition or Differential Learning of Multiple Techniques in Volleyball?
2021
A variety of approaches have been proposed for teaching several volleyball techniques to beginners, ranging from general ball familiarization to model-oriented repetition to highly variable learning. This study compared the effects of acquiring three volleyball techniques in parallel with three approaches. Female secondary school students (N = 42
Une dialectique de la mémoire et de l'oubli : "Hiroshima mon amour" de Marguerite Duras
2022
Hiroshima mon amour depicts tight relations between memory and oblivion. The novel ’s love story takes place in France ’s collective memory, but it also refers to the individual memory of a woman evoking past events. Consequently, the encounter with another human being (a man) allows her to confront her personal trauma. This confrontation can be perceived as a quest for one ’s own identity and history, i.e. the alienation history of an individual who – due to an unhappy love affair – cannot escape either the past or oblivion. The permeation of these two notions is emphasised by diverse time perspectives which overlap each other, allowing for an intertextual reading of Duras ’ script. Hence,…
KOSMOS 2017 Peru Side Experiment: nutrients, phytoplankton abundances, enzyme rates, photophysiology
2022
This data was collected during an short-term incubation experiment in March 2017 that investigated the response of a surface plankton community to upwelling. This experiment was carried in the framework of the SFB754-funded KOSMOS mesocosm study that took place in La Punta, Callao, Peru between February-April 2017. A total of six different treatments were used to disentangle chemical and biological characteristics of deep water that influence surface plankton blooms: 2 different deep water sources with different nutrient concentrations; 3 treatments to distinguish the effects of inorganic nutrients, organic nutrients and deep water microbial populations. Measured variables include inorganic…
La cohesió léxica en seqüències narratives.
2008
Aquesta tesi doctoral s'ocupa de les operacions discursivocognitivesd'establiment de referents i de represa lèxica de la referència en textos escritsd'estudiants de secundària.Partim d'un corpus doble constituït per seqüències narratives produïdes, d'unabanda, per alumnes de quart curs d'E.S.O (aprenents) i, d'altra banda, per periodistescinematogràfics (experts), que ens proporcionen el corpus de control i, doncs, la base decomparació de les produccions dels aprenents.En primer lloc, hem analitzat els diversos tipus d'estructures nominals ipredicatives que vehiculen la introducció dels referents discursius. En segon lloc, enshem ocupat de la represa lèxica dels referents mitjançant la repe…
Superhuman Cognitions, Fourth Dimension and Speculative Comics Narrative : Panel Repetition in Watchmen and From Hell
2016
Abstract: This article investigates the use of repeating panels in relation to speculative fiction storytelling in graphic novels Watchmen and From Hell , written by Alan Moore and illustrated by Dave Gibbons and Eddie Campbell, respectively. Presenting the same panel several times over the course of the narrative is an expressive medium-specific narrative technique available only to comics. In the discussed graphic novels, panel repetition is used to represent the superhuman cognitions of the quantum powered superhero Dr. Manhattan, as well as the magical experiences of Sir William Gull, the homicidal madman behind the brutal Jack the Ripper murders in Victorian London. Both characters hav…
Scientific writing for impact factor journals
2013
EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
Laser fluence, repetition rate and pulse duration effects on paint ablation
2006
Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…
