The tandem catalysis of ring-closing metathesis/atom transfer radical reactions was investigated with the homobimetallic ruthenium-indenylidene complex [(p-cymene)Ru(mu-Cl)(3)RuCl(3-phenyl-1-indenylidene)(PCy3)] (1) to generate active species in situ. The two catalytic processes were first carried out independently in a case study before the whole sequence was optimized and applied to the synthesis of several polyhalogenated bicyclic gamma-lactams and lactones from alpha,omega-diene substrates bearing trihaloacetamide or trichloroacetate functionalities. The individual steps were carefully monitored by H-1 and P-31 NMR spectroscopies in order to understand the intimate details of the catalytic cycles. Polyhalogenated substrates and the ethylene released upon metathesis induced the clean transformation of catalyst precursor 1 into the Ru(II)-Ru(III) mixed-valence compound [(p-cymene) Ru(mu-Cl)(3)RuCl2(PCy3)], which was found to be an efficient promoter for atom transfer radical reactions under the adopted experimental conditions.

This paper reports the results of an experimental investigation of the performance of two types of magnetic screens assembled from YBa2Cu3O7-d (YBCO) coated conductors. Since effective screening of the axial DC magnetic field requires the unimpeded flow of an azimuthal persistent current, we demonstrate a configuration of a screening shell made out of standard YBCO coated conductor capable to accomplish that. The screen allows the persistent current to flow in the predominantly azimuthal direction at a temperature of 77 K. The persistent screen, incorporating a single layer of superconducting film, can attenuate an external magnetic field of up to 5 mT by more than an order of magnitude. For comparison purposes, another type of screen which incorporates low critical temperature quasi-persistent joints was also built. The shielding technique we describe here appears to be especially promising for the realization of large scale high-Tc superconducting screens. [less ▲]

Acetaldehyde, the first metabolite of ethanol, has been suggested to be involved in many behavioral effects of ethanol. However, very few studies have been published on the role of acetaldehyde in the amnesic and ataxic effects of ethanol. The aim of the present studies was to compare the profiles of ethanol and acetaldehyde in several behavioral tests, measuring motor coordination, learning and memory in mice. Female Swiss mice were injected intraperitoneally with ethanol (0-3g/kg) and acetaldehyde (100-300mg/kg). The effects of these substances on a series of representative behaviors were investigated. The amnesic effects were tested with an object recognition task and a one-trial passive avoidance test. Additionally, the rectal temperatures were used to evaluate the hypothermic effects of the two substances. Finally, motor coordination was assessed using the accelerating rotarod test. The results showed that acetaldehyde, like ethanol, altered memory as shown by a reduced performance in the passive avoidance test and the object recognition task. In addition, acetaldehyde at doses between 100 and 300 mg/kg induced significant hypothermic effects, but that was of shorter duration than ethanol-induced hypothermia. Finally, significant ataxic effects of both acetaldehyde and ethanol were observed in the accelerating rotarod test. Overall, the results of the present study clearly show that acetaldehyde, like ethanol, has amnesic, hypothermic and ataxic properties in mice at least at relatively high concentrations. [less ▲]

Aim. Ecogeographical body size variation in vertebrates (e.g., Bergmann’s rule) has long been recognized. However, the patterns and causes of intraspecific ecogeographical body size variation in ectotherms, and in amphibians in particular, are strongly debated. We identified the relationship between bioclimatic variables and body size predicted a priori by alternative hypotheses (heat balance; endurance, seasonality, starvation resistance, water availability; primary productivity, parental investment) proposed to explain ecogeographical patterns of body size in ectotherms, and we evaluated the relative support of these hypotheses in explaining body size variation of the Italian crested newt, Triturus carnifex. Location Twenty-three populations covering the whole range of T. carnifex (Austria, Croatia, Italy and Slovenia) Methods. We obtained data on body size (SVL) of 2639 adult newts from direct measurements and the literature; we obtained high resolution environmental data for the sampled localities. We used an information-theoretic approach to evaluate the support of the different hypotheses, by the data. We also integrated information on population genetics in our models. Results. We observed strong geographic variation of body size. The best AIC models showed that populations with larger body size are associated with cold climates and secondarily with high primary productivity. Furthermore, sexual dimorphism increases in cold climates, as the increase in body size was stronger for females. When taking into account population genetics, we did not find support for relationships with the other variables. Main conclusion. Our results are consistent with three hypotheses proposed to explain ecogeographic variation in amphibians: heat balance, increased parental investment of females and productivity. Information theory provides the framework for comparing hypotheses rather than looking for patterns. We suggest that evaluating the support of mechanisms can provide better insights than simply assessing whether ecogeographical variation is in agreement with some ‘rule’. [less ▲]

Le document synthétise ce qui semble la ligne de fracture majeure au sein de la laïcité franco-belge : opposition entre une conception "républicaine" et une conception "libérale". Les deux peuvent se réclamer de la tradition laïque mais la première inclut une forme d'hostilité de principe à la religion qui est étrangère à la seconde. Le document tente de synthétiser les principales conséquences politiques de ces deux conceptions en passant en revue la neutralité des agents de l'Etat, la neutralité des citoyens et des élèves, ainsi que les discriminations indirectes et les accommodements raisonnables. Sur ces quatre points, les deux conceptions de la laïcité conduisent à des positions politiques différentes. Normativement, le document défend la primauté réelle, mais pas inconditionnelle, de la liberté d'expression. [less ▲]

A combination of scanning Hall microscopy and scanning ac-susceptibility measurements in superconducting stripes (ribbons) of width w < 10 mu m was used to observe the dimensional phase transitions of the vortex lattice and its stability under alternating fields. At low dc magnetic fields applied perpendicularly to the plane of the stripes, vortices form a one-dimensional chain at the center of the stripes. Above a certain field H*(w), the vortex chain splits in two parallel rows displaced laterally in such a way that a zigzag vortex pattern is observed. By shaking the vortices with an external magnetic ac field and detecting their in-phase motion locally, we can identify the degree of mobility of each individual vortex. This technique allows us (i) to directly visualize the transition from intravalley (Campbell regime) to intervalley vortex motion as the amplitude of the ac modulation is increased and (ii) to accurately determine the temperature at which the vortex lattice freezes in a field-cooling experiment.
