Volatile anesthetics are potent bronchodilators, but the site of action for the dilation is unclear. To determine the site of action of halothane, enflurane, and isoflurane on the peripheral vagal motor pathway, isolated strips of canine trachealis muscle were stimulated before and during exposure to halothane at 0.3, 1.0, 1.7, or 2.4 MAC, enflurane at 1 MAC, or isoflurane at 1 MAC. The sites and methods of stimulation were: 1) postsynaptic nicotinic cholinergic receptors in the intramural parasympathetic ganglia, with 1,1-dimethyl-4-phenyl-piperazinium iodide (DMPP); 2) postganglionic cholinergic nerve fibers, with electrical field stimulation (EFS); and 3) muscarinic cholinergic receptors of the smooth muscle, with acetylcholine (ACh). The concentration-response curve to DMPP was significantly shifted to the right by 0.3 MAC halothane, whereas 0.3 MAC halothane had no significant effect on the concentration-response curves to ACh and EFS. At concentrations greater than 1 MAC of halothane, enflurane, or isoflurane, concentration-response curves to all three stimuli were shifted significantly to the right; i.e., the contractile responses to ACh, EFS, and DMPP were reduced. At all concentrations of halothane the force of contraction was significantly more reduced during stimulation with DMPP than during stimulation with ACh, and at halothane concentrations greater than or equal to 1.7 MAC the response to EFS was significantly more reduced than that to ACh. We conclude that halothane, enflurane, and isoflurane attenuated airway constriction by several mechanisms, including 1) reduced excitability of the postsynaptic nicotinic receptors of the intramural parasympathetic ganglia and 2) an effect on the smooth muscle and/or on the muscarinic receptors.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Dans son logos lydien du Livre I, et plus particulièrement dans le cadre de son histoire de Crésus, Hérodote mentionne la campagne du roi lydien contre les troupes du roi des Perses Cyrus II le Grand après sa prise d’Ecbatane. Lorsque Crésus s’apprête à entrer en Cappadoce et à envahir la cité de Ptérie, le père de l’Histoire précise que la frontière qui séparait la Médie de la Lydie était le fleuve Halys. Après la description géographique de celui-ci, Hérodote précise en effet qu’un conflit avait opposé les Lydiens d’Alyatte (le père de Crésus) aux Mèdes de Kyaxare (le père d’Astyage, roi détrôné par Cyrus). Cette guerre se serait terminée sur un épisode célèbre qui est fixé en 585 av. J.-C. : l’éclipse totale du soleil qu’aurait prédite Thalès de Milet. C’est à la suite de ces hostilités, qu’un traité aurait été conclu entre les Lydiens et les Mèdes fixant leur frontière commune sur l’Halys. C’est du moins ce que la tradition fixée par l’historien des guerres médiques a retenu. Après cette incise, Hérodote reprend son récit en traitant du franchissement de son cours par Crésus ; il devait s’ensuivre sa débâcle en Ptérie, un désastre qui annonçait du coup aussi la fin de l’autonomie des cités grecques réduites à tomber sous le joug des Perses. Dans notre exposé, nous reviendrons sur cette vision que la tradition a gardée et qui fait de l’Halys la frontière entre la Médie et la Lydie. Ensuite, nous analyserons la description du cours de ce fleuve laissée par Hérodote. De plus, nous reviendrons sur les diverses mentions qu’en a faites le père de l’Histoire tout au long de son récit. Nous nous pencherons ainsi sur le rôle que le fleuve a rempli dans la vision de l’espace politique, ethnique et géographique au regard de l’historien d’Halicarnasse et les problèmes que sa présentation soulève. Enfin, nous verrons que chaque franchissement de ce fleuve par les barbares se révéla un mauvais présage pour les Grecs d’Asie mineure mais aussi pour ceux de la Grèce même. [less ▲]

Hamlet est une pièce qui s’adresse à tous les publics ou, à tout le moins, aux publics disposés à se poser, avec Hamlet, d’innombrables questions sur des sujets tels que la vie et la mort, l’action et l’inaction, l’amour ou encore la vengeance. Laurence Olivier a dit qu’il pourrait jouer Hamlet pendant cent ans et lui trouver un nouveau sens à chaque représentation. Le personnage est ambigu, presque insaisissable, en effet, comme l’est la langue de la pièce. Mais cette ambiguïté renforce la richesse de Hamlet plutôt qu’elle ne l’appauvrit ; et c’est précisément ce mystère qui permet à chaque lecteur et à chaque acteur de se livrer à une lecture personnelle et intime du personnage, de faire sienne sa complexité. Hamlet, c’est lui, toi, moi, c’est nous tous ; étant nous tous, il est universel, le mythe que chacun d’entre nous essaie, dans son individualité, de comprendre et ne peut s’empêcher de reconnaître dans sa propre nature. Les lectures de Hamlet sont innombrables et sont fonction de la personnalité du lecteur de la pièce, du metteur en scène et de l’acteur. Hamlet est un des rares personnages du théâtre, peut-être le seul, qui permette un échange constant. Chacun de nous, quel que soit son âge, peut se reconnaître en lui et peut façonner le mythe de Hamlet à son image. * Ne présupposant aucun savoir particulier, cet ouvrage introductif — destiné à la fois au grand public et aux étudiants de l'enseignement secondaire et du premier cycle universitaire — offre un aperçu critique des principaux thèmes de Hamlet tout en permettant au lecteur de se familiariser avec les interprétations et les prolongements littéraires et cinématographiques de la pièce.

This paper presents a research on an innovative stiffened extended end-plate joint, used to connect I-shaped beams to partially-encased composite wide flange columns. In the joint, T-shaped hammer heads cut from the same I-profiles than the beams are used, instead of using traditional haunches. At the joint level, the column web is strengthened by two lateral plates welded to the column flanges; these plates also reinforce the column flanges. This type of joint is proposed to use in the seismic resistance building frames, as a full-strength and a fully-rigid joint solution. Firstly, a test program carried out within a RFCS European project titled HSS-SERF “High Strength Steel in Seismic Resistant Building Frames”, 2009–2013, will be presented. Then, analytical developments based on the component approach and aimed at predicting the joint response will be described; their validity will be demonstrated through comparisons with the tests. Moreover, a new design concept for full strength joint accounting for the actual position of the plastic hinge and the possible individual overstrength factors for each component is proposed, respecting the requirements of EN1998-1-1.

Ionic liquids are salts with the particularity to exhibit melting points near room temperature (below 100°C, by convention) with no vapour tension. For this last reason, ionic liquids are sometimes called “green solvents”. In addition, their exclusive materials and solvent properties has led to an amazing increase of interest from both academic and industrial community, confirmed by the explosion of the number of published papers in the last decade. The many combinations of organic and inorganic cations and anions allow an infinity of new ionic solvents then permitting the selection of the desired properties for a given application. Nevertheless, it is impossible to investigate all these combinations and the unusual complexity of these new solvents gives rise to many controversies. Consequently, the development of the general rules for understanding the chemistry in ionic liquids is crucial. A fundamental property of solvent is its solvating power, for instance towards the proton. Therefore, we are interested to investigate the acid-base properties in ionic liquids in order to ultimately find a correlation with the acidic catalysis activity. We then have proposed a colorimetric method to determine the acidity levels accessible in these new media: the Hammett acidity function H0. This spectroscopic method is based on the protonation equilibrium for a family of coloured indicator with pKa’s assumed as solvent independent (following the Hammett proposition). This presentation will summarize our Hammett acidity measurements in several ionic liquids. - At first, we will show that it is possible to evaluate the Hammett acidity function with two different coloured indicators, in the same ionic liquid. Since the Hammett acidity of a given mixture was found to depend on the choosen coloured indicator, this suggests the formation of ions associations in ionic liquids. As a result, the ionic liquids are clearly not as dissociating as initially thought and the Hammett acidity function is in fact an apparent function, underestimating the real acidity level. - The apparent acidity functions have then been compared for several ionic liquids to which an acid has been added ([BMIm][NTf2], [BMIm][BF4], [BMIm][OTf], [BHIm][NTf2], [BMIm][PF6], [HNEt3][NTf2]). The conclusions are as follows: 1) the accessible acidity level is not influenced by the nature of the cation; 2) on the contrary, the nature of anion is very critical and the solvating power towards the proton follows the order: OTf- > NTf2- > BF4- > PF6-. The more the proton is solvated, the less it is acidic. - Finally, the difference of acidity of two acids, HOTf and HNTf2 (both strong acids in water), has been investigated in [BMIm][BF4], [BMIm][NTf2] and [BMIm][OTf]. In [BMIm][OTf], these two acids show the same acidity (they behave as strong acids) due to the solvent levelling effect; on the other hand, in [BMIm][NTf2] and [BMIm][BF4] allowing higher acidity levels, HNTf2 is stronger than HOTf . The observed difference is also another indication of the lower proton solvation in [BMIm][BF4] or [BMIm][NTf2] versus that in [BMIm][OTf]. [less ▲]

Fossif remains of hamsters from the late Pleistocene were found in Belgium. But this animal seems to have disappeared between that period and the mid 19th century. When again registrated it was only found in the "le pays de Herve" between Herve and Limbourg. Then it progressively reached the center of Brabant, the westernmost part of its range. In the early 20th century, hamsters were so numerous that people were going through an aradication campaign to prevent the damaging of their crops. However, we believe that the major reasons of its present scarcity were the sound modifications of the agricultural technology and landscape (mechanization, regrouping of land, deep ploughing after the harvest...) Hamsters live now in Hesbaye, the Pays de Herve and in the east of Brabant. But they are so few that it appears to take some conservation measures [less ▲]

We determined the frequency of strength disorders in 26 athletes with a history of hamstring muscle injury and recurrent strains and discomfort. We also assessed the effectiveness of rehabilitation to correct muscle performance. After concentric and eccentric isokinetic assessment, 18 athletes were found to have strength deficits, as determined by statistically selected cutoffs of peak torque, bilateral differences, and the flexors/quadriceps ratio. The discriminating character of the eccentric trial was demonstrated, combining a preferential eccentric peak torque deficit and a significant reduction of the mixed eccentric flexors/concentric quadriceps ratio. The athletes with muscle imbalances followed a rehabilitation program individually adapted from their strength profile. Treatment length was from 10 to 30 sessions and resulted in isokinetic parameter normalization in 17 of 18 subjects. Isokinetically corrected subjects were observed for 12 months after return to athletics. None sustained a clinically diagnosed hamstring muscle reinjury. Subjective intensity of pain and discomfort were significantly reduced, and they all returned to their prior level of competition. These results demonstrate that persistent muscle strength abnormalities may give rise to recurrent hamstring injuries and discomfort. An individualized rehabilitation program emphasizing eccentric training based on specific deficits contributes to a decrease in symptoms on return to sports. [less ▲]

Exaggerated test conditions were frequently used to investigate the cutaneous tolerance of detergent products in the past. As the sensitivity of newly designed biometric methods is steadily improving, the trend towards more realistic test conditions should be encouraged. A hand immersion test under laboratory-controlled usage conditions is presently described, fulfilling such principles. Panelists soaked their hands in 2 different hand dishwashing liquids, 2x daily for 10 min each (with successive in-solution/out-of-solution cycles) for 4 consecutive days. Products were at usual dilution for dishwashing liquids and were randomized between the dominant and non-dominant hands of panelists. Visual scoring of erythema and dryness developing on the whole hands (scoring scales including interdigital areas and joints) during the week did not allow discrimination between the 2 products. However the dominant hands were significantly more susceptible to alterations than the non-dominant hands, regardless of product attribution. In contrast, skin electrical measurements (Corneometer CM800 and Skicon 200) on the dorsum of the hands (muscle mass between thumb and index) and squamometry analysis of tape stripping (harvested from the same site) yielded significant differences between the 2 products. In conclusion, a hand immersion test under realistic conditions has been described, which discriminates between products when sensitive assessment methods are used to explore skin sites partially protected from daily-life skin aggressions.

The postharvest development of crown rot of bananas depends notably on the fruit susceptibility to this disease at harvest. It has been shown that fruit susceptibility to crown rot is variable and it was suggested that this depends on environmental preharvest factors. However, little is known about the preharvest factors influencing this susceptibility. The aim of this work was to evaluate the extent to which fruit filling characteristics during growth and the fruit development stage influence the banana susceptibility to crown rot. This involved evaluating the influence of (a) the fruit position at different levels of the banana bunch (hands) and (b) changing the source–sink ratio (So–Si ratio), on the fruit susceptibility to crown rot. The fruit susceptibility was determined by measuring the internal necrotic surface (INS) after artificial inoculation of Colletotrichum musae. A linear correlation (r = −0.95) was found between the hand position on the bunch and the INS. The So–Si ratio was found to influence the pomological characteristics of the fruits and their susceptibility to crown rot. Fruits of bunches from which six hands were removed (two hands remaining on the bunch) proved to be significantly less susceptible to crown rot (INS = 138.3 mm2) than those from bunches with eight hands (INS = 237.9 mm2). The banana susceptibility to crown rot is thus likely to be influenced by the fruit development stage and filling characteristics. The present results highlight the importance of standardising hand sampling on a bunch when testing fruit susceptibility to crown rot. They also show that hand removal in the field has advantages in the context of integrated pest management, making it possible to reduce fruit susceptibility to crown rot while increasing fruit size.
