The reduction of the thermal background emission from the local and exozodiacal dust clouds is a critical element for the success of ESA's space mission, DARWIN. Internal modulation, a technique using fast signal chopping, isolating the planetary signal from these noise sources, was proposed by Mennesson and Léger. In this paper, a short review of internal modulation is given, and new configurations with internal modulation are proposed to reduce the complexity of the beam-combining optics. A modification to the implementation of internal modulation is then investigated. It provides similar performance with a single detector and a greatly simplified optical layout: the number of beam-combiners is reduced by a factor of about two. The principle of inherent modulation is different from internal modulation in that no sub-interferometers are used: different phase shifts are applied to the input beams before recombination such that an asymmetric transmission map is obtained directly, without plus or minuspi/2 modulation as used in internal modulation. By combining the phase shifts and the input beams differently a transposed transmission map is obtained, allowing the signal to be chopped. During operations, multiplexing between the two interferometers is performed, such that at any time only one interferometer is being used. [less ▲]

This paper studies the effects of variables pertaining to alternative bequest motives on the composition of households' portofolio. It relies on a 1986 survey on the assets structure of 5600 French households. The main conclusion is that bequest motives indeed influence the composition of households' wealth. However, available data does not allow one to sort out the influence of specific models of inheritance. [less ▲]

This paper reports a study on the sex determination system of the blue tilapia, Oreochromis aureus. Investigations were carried out using a pseudofemale line in two populations of O. aureus, known as Egyptian Population (EP) and Israel Population (IP). In O. aureus, males are the homogametic sex (ZZ/ZW), and sex reversal of fry with estradiol results in the production of some functional sex-reversed fish with a female phenotype and ZZ male genotype, known as pseudofemales or A-females. Crosses between ZZ pseudofemales and ZZ males theoretically should provide monosex ZZ male progeny only. We have studied the sex ratios of progeny from 43 IP (F-2 to F-3 generations) and 51 EP (F-1 to F-5 generations), pair-matings between normal males and pseudofemales. In IP, the male percentage in progenies ranged between 83% to 100% in F-2 and 66% to 100% in F-3. In EP, male percentage was more constant, varying from 88% to 100% in F-1, from 96% to 100% in F-3 and from 97% to 100% in F-5. In EP, F-2 and F-4 pseudofemales produced only monosex male progeny. This apparent difference in sex ratio frequency distributions between the two O. aureus pseudofemale lines could be due to the selection of males. EP pseudofemales were mated with their siblings for F-2 and F-3 pseudofemales or with closely related males for F-4 and F-5 pseudofemales. Conversely, IP pseudofemales were crossed with nonrelated males originating from research center broodstock, resulting in a higher proportion of females in sex ratio of progenies from successive generations of pseudofemales. The role of inbreeding is discussed in the context of predominantly monofactorial sex chromosome determination system operating in this species, influenced by other factors (genetic and environmental). The present study also shows that it is possible to fix the male sex determining factors (Z sex chromosome and genetic factors) in a line of pseudofemales, producing a high percentage of male progeny in five successive generations.

Les inhibiteurs de l'enzyme de conversion nous donnent pour la première fois la possibilité d'inhiber l'activité du système rénine-angiotensine chez les patients hypertendus. Ces vasodilatateurs n'entraînent ni tachycardie réflexe, ni rétention hydrosodée. Leur utilisation ne s'accompagne pas de modifications métaboliques mais certains effets secondaires (toux, altération de la fonction rénale), liés d'ailleurs au mode d'action, ont été relevés. Bien tolérés, ces dérivés peuvent être utilisés en monothérapie dans le traitement de l'hypertension légère, mais leur supériorité par rapport aux diurétiques et aux bêtabloquants dans la prévention des complications cardiovasculaires de l'hypertension reste à établir.

Inhibitors of the renin-angiotensin system have proved their great value in secondary prevention trials for cardiovascular or renal complications. In favour of the preferred use of angiotensin receptor antagonists stand their excellent tolerance and the possible therapeutic escape seen with angiotensin converting enzyme inhibitors. For the preferential use of the latter, the arguments are the absence of a real proof of any superiority of the angiotensin receptor blockers and their higher cost. The wisdom is to initially use angiotensin converting enzyme inhibitors in secondary prevention excepted when they are not well tolerated. The large ONTARGET cardiovascular prevention trial should help solve this controversy. [less ▲]

De nombreuses, peut-être de trop nombreuses molécules, dotées d'un pouvoir d'inhibition de l'enzyme de conversion ont été introduites ces dix dernières années pour le traitement de l'hypertension artérielle et de l'asystolie. Les différences entre ces molécules sont peu importantes et sont fonction de leur structure moléculaire. Le captopril, seul dérivé doté d'un groupe sulfhydrile, a un effet rapide et de durée assez brève; son utilisation s'accompagne par ailleurs de certains effets secondaires propres au groupe SR. Par contre, le délai d'action des dérivés dont le ligand est un groupe carboxyle est généralement plus tardif, leur durée d'action plus longue, justifiant une prise par jour. Il reste difficile d'affirmer que le groupe SR confère des propriétés cardioprotectrices plus importantes que celles dont jouissent les autres molécules de cette classe thérapeutique. De la même manière, à ce stade, les différences démontrées concernant la diffusion tissulaire des inhibiteurs de l'enzyme de conversion n'ont pas pu être illustrées par des observations cliniques.

The effect of ammonia on the cough response to citric acid and on substance P release from C-fibers involved in this reflex was assessed. For a period from one to four days, piglets were exposed, in an inhalation chamber, to ammonia at a concentration of 15 or 30 ppm. During exposure, cough induction tests were done every two days. Recovery of the cough reflex after ammonia exposure was also determined. In a separate group of piglets exposed for 2 days to 30 ppm ammonia, substance P content was determined in bronchial and tracheal lavage fluids and in the tracheal and bronchial mucosa. Ammonia (30 ppm) was found to inhibit coughing significantly (the cough frequency was reduced by 64%) after a two-day exposure. In animals exposed for 4 days to this ammonia concentration, the recovery ranged from 3 to 7 days (mean: 5 days). The same ammonia concentration also caused the substance P content to increase significantly in bronchoalveolar lavage fluid (to 432% of its initial value) and tracheal lavage fluid (to 149%) and to decrease significantly in the tracheal mucosa (-58%), however the content in bronchial mucosa was not significantly affected (-43%). Exposure to 15 ppm ammonia had no effect on the frequency of citric acid-induced coughing. In conclusion, ammonia inhibits citric acid-induced coughing in pigs at concentrations that can be detected in piggeries. This inhibitory effect may be related to substance-P depletion in C-fiber endings [less ▲]
