Introduction The muscle injury, and more especially the hamstring strain, account for a large proportion of explosive top athletes injuries [1-3]. The subsequent down-time period has some sports and financial negatives consequences for the athlete, his team and/or his club [4, 5]. Despite the rehabilitation before return to play and prevention program, hamstring reinjury rates are still high (26% of all injuries) [6] and it's commonly accepted that a second injury is more severe than a first episode [2]. A more functional test could help the clinician in the return to play process decision to reduce the muscle injuries hamstring relapse. Purpose The aim of our methodology is to analyze, after medical clearance to resume sports activities, for athletes who suffered from grade II/III hamstring muscle strain, the biomechanics of the lower limbs during an explosive jump task. Method After (7,3±0,7 weeks) a grade II or III hamstring muscle tear, eight men (25±5,9 years), without past lower limb major injury, performed: - an isokinetic test (knee maximal flexion-extension in concentric at 60°.s-1 and 240°.s-1 and knee maximal flexion in eccentric at 30°.s-1); - a tridimensional biomechanics analysis of (bipodal and unipodal) squat jump and counter movement jump with Codamotion® system and Kistler® multicomponent force plates. Results A muscular lateral strength imbalance (±10% with p-value < 0,02) has been identified on the hamstring in concentric and eccentric by means of isokinetic testing, with the healthy side stronger than the pathologic. The main statistical significant outcome in the biomechanics analysis is the lower knee angle (±12% with p-value < 0,02) at the low point before the concentric pushing phase of the unipodal CMJ for the healthy leg than to the other one whereas there's no difference between both legs in an equivalent healthy population. Discussion & conclusion The tridimensional analysis appears to be complementary, not redundant, with the isokinetic strength testing due to the different nature of their informations obtained. It could be integrated in the return to play process decision expected the potentially interesting information about the player's biomechanics that it provides. References 1. Ekstrand, J., M.

Contrairement aux empiristes anglais, Wittgenstein récuse l’idée d’après laquelle les actes d’imagination sont définis par leur « contenu », à savoir une « image mentale » qui ne différerait que par son degré d’intensité d’un contenu cognitif (Cf. Hume, Traité de la nature humaine, I, i, 3 ; Wittgenstein, F §621). Parallèlement, Wittgenstein récuse l’hypothèse selon laquelle un « œil mental » ou « œil interne » nous fournirait ces images (cf. e.g. RPP II §66). De fait, les nombreux exemples des Recherches philosophiques comme des textes plus tardifs (cf. e.g. RP §§6, 19 ; F §§98, 571) mettent en scène l’imagination d’un langage, d’une hypothèse, d’un usage, d’un contexte, etc. – autant de choses que l’on ne « voit » pas par l’œil de l’esprit. En adoptant une position assez proche de celles de Reid, Ryle ou Sartre (cf. Glock 1996), Wittgenstein défend alors l’hypothèse d’une imagination sans imaginaire. Ce faisant, Wittgenstein présente l’imagination comme un acte, ou plutôt une « pratique ». Or Wittgenstein dissocie cette pratique de celle de la perception (F §§621-637). Selon le §625 des Fiches, il existe bien un « rapport » entre ces deux jeux de langage, mais pas de « ressemblance ». À titre de premières indications, il semble que les deux pratiques diffèrent pour au moins trois raisons : - Premièrement, Wittgenstein affirme que l’imagination, à la différence de la perception, est assujettie à la volonté (e.g. F §621). Si nous recevons ce que nous percevons, nous pouvons en revanche répudier ou rechercher certaines images. - Qui plus est, en tant que pratique volontaire, l’imagination est soumise aux mêmes règles que celles qui régulent toutes les pratiques. C’est donc une pratique normée : en situation, certaines représentations sont possibles alors que d’autres pas (cf. e.g. RP, §651 : « je ne peux pas imaginer le contraire »). - Il semble enfin que l’imagination, à la différence de la perception, soit une pratique créatrice. Wittgenstein rapproche en effet l’imagination du « voir comme » et non du voir (RP II, 11, RPP §543). Elle joue à ce titre un rôle méthodologique fondamental dans l’économie de la vision synoptique que Wittgenstein appelle de ses vœux. [less ▲]

Due to their high trophic position and long life span, small cetaceans are considered as suitable bioindicators to monitor the presence of contaminants in marine ecosystems. Here, we document the contamination with persistent organic pollutants (POPs) and total mercury (T-Hg) of spinner (Stenella longirostris, n=21) and Indo-Pacific bottlenose dolphins (Tursiops aduncus, n=32) sampled from the coastal waters of La Réunion (south-western Indian Ocean). In addition, seven co-occurring teleost fish species were sampled and analyzed as well. Blubber samples from living dolphins and muscle from teleosts were analyzed for polychlorinated biphenyls (PCBs), DDT and metabolites (DDTs), chlordanes (CHLs), hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), and polybrominated diphenyl ethers (PBDEs). Methoxylated PBDEs (MeO-PBDEs), reported as having a natural origin, were also analyzed. T-Hg levels were measured in blubber and skin biopsies of the two living dolphin species. δ13C and δ15N values were determined in skin of the dolphins and in the muscle of teleosts. For PCBs, HCHs and T-Hg, concentrations were significantly higher in T. aduncus than in S. longirostris. For other POP levels, intra-species variability was high. MeO-PBDEs were the dominant compounds (55% of the total POPs) in S. longirostris, while PCBs dominated (50% contribution) in T. aduncus. Other contaminants showed similar profiles between the two species. Given the different patterns of POPs and T-Hg contamination and the stable isotope composition observed among analyzed teleosts, dietary and foraging habitat preferences possibly explain the contrasted contaminant profiles observed in the two dolphin species. Levels of each class of contaminants were significantly higher in males than females. Despite their spatial and temporal overlap in the waters of La Réunion, S. longirostris and T. aduncus are differently exposed to contaminant accumulation. [less ▲]

Deltas are complex hydrosystems and ecosystems resulting from the interactions of a river system with a water body almost at rest. Anthropogenic factors (hydropower, flood management, development in the floodplains) lead to dramatic changes in sediment transport in the rivers and in sediment management practice. From continuous, the sediment transport becomes increasingly intermittent, with long periods of deficit in the sediment supply and short periods characterized by large supplies. Understanding how these intermittencies in the sediment supply affect the delta morphodynamics is of paramount importance for predicting the possible evolution and functioning of deltas. Deltas can reasonably be idealised as a reservoir, with an inlet channel representing the river and the sud- den enlargement of the reservoir representing the water body at rest. Using such an ideal configuration enables the assessment of the influence of individual geometric and hydraulic parameters on the depositional patterns responsible for the morphodynamic evolution of the delta. Recent literature has shown that for very similar hydraulic boundary conditions, two very different types of flow fields may develop (“straight jet” vs. “meandering jet”), leading to totally different depositional patterns. In turn, these distinct depositional patterns affect the flow itself through a two-way coupling between the hydrodynamics and the morphodynamics of the deposits. These complex processes will be discussed in the proposed presentation, based on the results of over 160 experimental tests and corresponding numerical simulations. [less ▲]

Microwave-assisted extraction was employed to extract polysaccharides from pumpkin biomass and compared to the usual extraction by conventional heating. The effect of microwave heating time, liquid/solid (L/S) ratio and extraction temperature on the yield and molecular mass of extracted pectin from the seeded oil pumpkin biomass was investigated. Heating times ranged from 2 to 10 min, L/S ratio from 30/1 to 50/1 and temperature from 80 to 120 °C. The response surface methodology was used to optimize the effects of processing parameters to isolate pectin with medium molecular weight and with the highest yield. The retained conditions were as follows: liquid/solid ratio 50/1, microwave heating time of 10 min and a temperature of 102.2 °C. Among the studied factors, the liquid/solid ratio had the greatest influence on yield and molecular mass, respectively. Application of microwave heating in the extraction of pumpkin biomass gave a pectin with medium Mw and dramatically reduced extraction time in comparison to traditional hot acid extraction. Microwave is an excellent tool for extraction and modification of polysaccharides in one step. [less ▲]

Alors que les études cliniques se focalisent principalement sur un problème de santé spécifique avec des patients vierges de comorbidités, il ressort d’une étude épidémiologique publiée en 2012 (1) que la multimorbidité, définie comme la présence d’au moins 2 maladies chroniques), augmente substantiellement avec l’âge (≥ 65 ans) mais qu’en nombre absolu de patients, elle touche plus de patients plus jeunes (plus de 50% en dessous de 65 ans). Près d’un tiers de ces patients multimorbides souffre de problèmes de santé mentale (dépression, troubles psychotiques, etc.), dont la gravité augmente avec le nombre de comorbidités et le statut socio-économique. L’étude analysée ici fait l’hypothèse d’un bénéfice d’un modèle de soins collaboratif et intégré en première ligne de soins sur la dépression et la gestion de la maladie chronique par le patient, tout en veillant à sélectionner une population représentative du constat démographique actuel de multimorbidité.

Drainage of water in soils happens for a large extent through preferential flowpaths, but these subsurface flowpaths are extremely difficult to observe or parameterize in hydrological models. To potentially overcome this problem, thermodynamic optimality principles have been suggested to predict effective parametrization of these (sub-grid) structures, such as the maximum entropy production principle or the equivalent maximum power principle. These principles have been successfully applied to predict heat transfer from the Equator to the Poles, or turbulent heat fluxes between the surface and the atmosphere. In these examples, the effective flux adapts itself to its boundary condition by adapting its effective conductance through the creation of e.g. convection cells. However, flow through porous media, such as soils, can only quickly adapt its effective flow conductance by creation of preferential flowpaths, but it is unknown if this is guided by the aim to create maximum power. Here we show experimentally that this is indeed the case: In the lab, we created a hydrological analogue to the atmospheric model dealing with heat transport between Equator and poles. The experimental setup consists of two freely draining reservoirs connected with each other by a confined aquifer. By adding water to only one reservoir, a potential difference will build up until a steady state is reached. From the steady state potential difference and the observed flow through the aquifer, and effective hydraulic conductance can be determined. This observed conductance does correspond to the one maximizing power of the flux through the confined aquifer. Although this experiment is done in an idealized setting, it opens doors for better parameterizing hydrological models. Furthermore, it shows that hydraulic properties of soils are not static, but they change with changing boundary conditions. A potential limitation to the principle is that it only applies to steady state conditions. Therefore the rate of adaptation of hydraulic properties should be faster than the rate of change in boundary conditions. [less ▲]
