Halato-telechelic polymers (HTP) result from the complete ionization of both ends of telechelic prepolymers. Their behavior in nonpolar solvents is characterized by a very abrupt increase of viscosity at increasing concentration, so that gel formation is noted at concentrations as low as 1.5 gdL-'. The nature of the ion pairs, polarity of the medium, and temperature influence significantly the gel formation and prove its electrostatic origin. The depressive effect of any polar additive on the gelation requires drastic conditions in the synthesis of reproducible materials. In this respect, an efficient synthetic pathway has been proposed. The influence of molecular weight and end-to-end distance of the prepolymer shows the determinant role played by the polymeric backbone on the ion aggregation process. [less ▲]

Alkaline earth alpha,omega-dicarboxylatopolybutadienesd issolved in a nonpolar solvent (an= 4600) display an attractive thermorheological simplicity and exhibit a secondary relaxation characteristic of the ionic component. The shear-thickening character of these solutions is to be outlined. Their deformation mechanism is controlled by the stability and the mean size of the ionic multiplets formed by the carboxylate end groups. The electrostatic origin of the viscoelastic behavior observed is well established by its dependence on solvent, temperature, and cation size. [less ▲]

Although the phenomenological diversity of hallucinations has been well documented, experimental investigations into their cognitive underpinnings have not yet reflected this complexity. Our goal in this review is to contrast the restricted set of experimental conditions that have been utilized in source-monitoring studies of hallucinations with their documented phenomenological diversity. In particular, we initially focus on the theoretical distinction between origin and source that has been recognized at the level of phenomenology, and then review the source-monitoring literature within this theoretical framework. In addition, we touch on several other aspects of the phenomenological diversity of hallucinations that have not yet been sufficiently investigated experimentally-namely, intentionality, affect, and motivational factors. Finally, we list other methodological problems that may have led to inconsistencies in the literature. We conclude with concrete recommendations for future source-monitoring investigations of hallucinations. [less ▲]

Studies of the anesthetic effects on the airway often use pulmonary resistance (RL) as an index of airway caliber. To determine the effects of the volatile anesthetic, halothane, on tissue and airway components of RL, we measured both components in excised canine lungs before and during halothane administration. Tissue resistance (Rti), airway resistance (Raw), and dynamic lung compliance (CL, dyn) were determined at constant tidal volume and at ventilatory frequencies ranging from 5 to 45 min-1 by an alveolar capsule technique. Halothane decreased RL at each breathing frequency by causing significant decreases in both Raw and Rti but did not change the relative contribution of Rti to RL at any frequency. Halothane increased CL,dyn at each breathing frequency, although there was little change in the static pressure-volume relationship. The administration of isoproterenol both airway and tissue components of RL; it may act by relaxing the contractile elements in the lung. Both components must be considered when the effects of volatile anesthetics on RL are interpreted. [less ▲]

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 ▲]
