les armes dites à létalité réduite sont des armes de neutralisation momentanée utilisées par les forces de police et les forces armées. Intermédiaires entre l'arme à feu et le contrôle manuel, elles demandent du discernement dans l'action. La doctrine d'emploi ne peut pas tabler uniquement sur la technologie; elle doit faire le point sur les conditions réelles d'applicabilité et d'acceptabilité. [less ▲]

Le mythe d'Orion, dont on ne connaît aucune version complète dans l'Antiquité et qui est attesté surtout à des époques tardives, est complexe. Depuis l'épopée homérique, Orion est présenté tantôt comme héros tantôt comme constellation. Les armes attribuées au héros au cours des épisodes de sa vie sont une massue, ce qui caractérise un personnage des temps très anciens, et, plus tardivement, un glaive. La constellation est munie d'un arc, d'un baudrier et d'une épée, ce qui semble indiquer un guerrier semblable aux héros aristocratiques, en tout cas un personnage plus avancé dans la marche de la civilisation. En devenant constellation, Orion, ainsi que son armement, ont été en quelque sorte "civilisés". [less ▲]

Droplets and bubbles protected by armors of particles have found vast applications in encapsulation, stabilization of emulsions and foams, or flotation processes. The liquid phase stores capillary energy, while concurrently the solid contacts of the granular network induce friction and energy dissipation, leading to hybrid interfaces of combined properties. By means of nonintrusive tensiometric methods and structural measurements, we distinguish three surface phases of increasing rigidity during the evaporation of armored droplets. The emergence of surface rigidity is reminiscent of jamming of granular matter, but it occurs differently since it is marked by a step by step hardening under surface compression. These results show that the concept of the effective surface tension remains useful only below the first jamming transition. Beyond this point, the surface stresses become anisotropic. [less ▲]

The presence of aromatase (estrogen synthase) in neurons in the dorsal horn of the spinal cord in Japanese quail suggests that estrogens produced locally from androgens could control spinal sensory processes including nociception. We used the hot water nociceptive test (54 degreesC) to appraise the longterm effect of an inhibition of aromatization on the foot withdrawal latency in male quail. Four weeks after the ablation of their main source of testosterone (testes), castrated males displayed a significantly higher foot withdrawal latency than gonadally intact males. A prolonged treatment with subcutaneous capsules filled with testosterone or 17 beta-estradiol restored the baseline latency within 2 weeks. The effect of testosterone in castrated quail was almost completely blocked by systemic injections of Vorozole((TM)), a nonsteroidal aromatase inhibitor or tamoxifen, an estrogen receptor antagonist (one injection per day for 10 days). Taken together, these data demonstrate for the first time to our knowledge an effect of estrogens formed by aromatization of androgens on nociception. Because aromatase-immunoreactive neurons and aromatase activity are present in the dorsal horns of the spinal cord, this control of pain thresholds is presumably mediated, at least in part, by estrogens produced at the spinal level that act locally via slow, presumably genomic, mechanisms mediated by the activation of spinal nuclear estrogen receptors.

We recently showed, using a new immunocytochemical technique, that aromatase-immunoreactive neurons are a specific marker for the sexually dimorphic medial preoptic nucleus (POM) in quail and that the number of these immunoreactive cells is markedly increased by a systemic treatment with testosterone (T). Since the POM is a key site for the activation of copulatory behavior by T and this androgen must be converted into estrogen by local aromatization within the POM before it can exert its behavioral effects, we used aromatase immunocytochemistry to map, at a cellular level of resolution, the areas that are destroyed by electrolytic lesions or that are stimulated by the stereotaxic implantation of T in the preoptic area (POA). These measures of the cellular action of T in the preoptic area were then correlated with the behavior of the animals to identify the parts of the POA that are critical in the activation of behavior. The electrolytic lesions of the POA disrupted the activation of male sexual behavior by T only if they destroyed a significant part of the POM. All lesions reduced the volume of the dimorphic nucleus and the absolute number of its aromatase-immunoreactive neurons, but the density of these cells in the remaining POM was not affected, suggesting that the volume change in the nucleus reflected a centripetal displacement of its boundaries rather than an overall shrinkage of the structure. Stereotaxic T implants in or close to POM activated male copulatory behavior and increased the volume of the POM and the number of its aromatase-immunoreactive cells. These neuroanatomical effects were more prominent on the side of the implant, but they were also detected on the contralateral side. Correlative analyses suggested that a part of the POM just rostral to the anterior commissure is critical for the activation of copulatory behavior. The best correlations between the behavioral deficits induced by electrolytic lesions and the size of the lesions were indeed observed in this area. In addition, high correlations were also observed between the behavior activated by T implants and the POM size or number of aromatase-immunoreactive cells that were induced by T in this area. Aromatase immunocytochemistry therefore appears as a useful tool to map the brain areas in which T action is presumably critical for the activation of male sexual behavior. It has allowed us to identify in the present studies a small part of the sexually dimorphic POM that is closely associated with behavior.(ABSTRACT TRUNCATED AT 400 WORDS) [less ▲]

Two experiments investigated the role of estrogens in the activation and sexual differentiation of appetitive sexual behavior (ASB) in Japanese quail (Coturnix japonica) as measured by a learned social proximity response. Injection of the aromatase inhibitor R767 13 in castrated, testosterone (T)-treated male quail completely suppressed ASB, confirming that, like consummatory sexual behavior, ASB is mediated by T aromatization. ASB is not observed in female quail, even if they are treated with T as adults. The role of embryonic estrogens in the sexual differentiation of ASB was tested by blocking estrogen synthesis in ovo. Control male and T-treated female quail deprived of estrogens during embryonic life learned the social proximity response used to assess ASB, whereas control female quail did not, despite the presence of high T. Thus, ASB is demasculinized by the action of embryonic estrogens during ontogeny as is consummatory behavior. [less ▲]

In Japanese quail (Coturnix japonica), activation of appetitive and consummatory aspects of male sexual behavior requires aromatization of testosterone (T) into estrogens. Appetitive male sexual behavior (ASB) is usually assessed with the use of a learned social proximity procedure. In the present experiment, we investigated the role of estrogens in the activation of an another index of ASB. the female-induced activation of rhythmic cloacal sphincter movements (RCSMs) that are produced in reaction to the visual presentation of a female. Consummatory sexual behavior (CSB) was also assessed by the frequency and latency of copulatory behaviors. Castrated male quail were treated with Silastic implants filled with T in association with chronic injections of the aromatase inhibitor Vorozole(TM) (R83842; 1 mg/kg twice a day; CX + T + VOR group). Control birds were implanted with T capsules only (CX + T group). CSB was almost completely blocked by injections of the aromatase inhibitor. The RCSM frequency decreased progressively in the CX + T + VOR group by comparison with the CX + T group and was therefore significantly reduced at the end of the experiment. These results demonstrate that the frequency of RCSM, a second measure of ASB is, like the social proximity response and CSB, blocked by inhibition of estrogen production. It was shown previously that lesions of the preoptic area inhibit both aspects of the appetitive sexual behavior (proximity response and RCSM). It is therefore, likely that both responses are controlled, like copulation, by aromatase-containing neurons of the preoptic area. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

Recent evidence has implicated steroid hormones, specifically estrogens, in the rapid modulation of cognitive processes. Songbirds have been a useful model system in the study of complex cognitive processes including birdsong, a naturally learned vocal behavior regulated by a discrete steroid-sensitive telencephalic circuitry. Singing behavior is known to be regulated by long-term actions of estrogens but rapid steroid modulation of this behavior has never been examined. We investigated if acute actions of estrogens regulate birdsong in canaries (Serinus canaria). In the morning, male canaries sing within minutes after light onset. Birds were injected with fadrozole, a potent aromatase inhibitor, or vehicle within 2-5 minutes after lights on to implement a within-subjects experimental design. This single injection of fadrozole reduced the motivation to sing as well as song acoustic stereotypy, a measure of consistency over song renditions, on the same day. By the next day, however, all song measures that were affected had returned to baseline. This study indicates that estrogens also act in a rapid fashion to regulate two distinct features of song, a learned vocal behavior. [less ▲]
