A comparative study of the dorval vessels of bees National Institute of Agronomic Research
Wille, Alvaro.
Two main types of dorsal vessels were found in the 101 species dissected, representing 61 genera and including most of the major groups of bees. In one type the dorsal vessel is straight and ruris dorsal to the gut; in the other type it makes an arch between the dorsal longitudinal muscles of the thorax, sometimes with a series of loops just behind the ascending portion. Intermediate types occur. Within any family or tribe in which both main types occur, that with the straight thoracic portion is always found in the primitive forms; and vessels with a series of loops are found only in the most specialized bees. An evolutionary trend is evident toward reduction of the posterior section of the dorsal vessel and its ostia. In the Meliponini, or stingless...

A comparative study on morphology, growth rate and reproduction of Clarias gariepinus (Burchell, 1822), Heterobranchus longifilis Valenciennes, 1840, and their reciprocal hybrids (Pisces, Clariidae) IRD
Legendre, Marc; Teugels, G.G.; Cauty, C.; Jalabert, B..
Successful reciprocal hybridizations between #Clarias gariepinus$ and #Heterobranchus longifilis$ were performed during three experiments. The reciprocal hybrids were viable, their survival rates being similar to those found in the maternal species. Hybrid morphology was intermediate to that of the parents. No difference in external morphology was found between the reciprocal hybrids. Growth rate comparison under the same conditions and over a period of 307 days, revealed a considerably faster growth for #H. longifilis$ x male #C. gariepinus$ hybrids displayed an even faster growth than #H. longifilis$.

A comparison of coincidental time series of the ocean surface height by satellite altimeter, mooring, and inverted echo sounder IRD
Katz, E.J.; Busalacchi, A.; Bushnell, M.; Gonzalez, F.; Gourdeau, Lionel; McPhaden, M.; Picaut, Joël.
Altimetric measurements of sea surface height at two locations in the western tropical Pacific Ocean are compared to estimates of the dynamic sea surface height computed from cotemporal surface-to-bottom temperature/salinity measurements on moorings and acoustic travel time measured by bottom-moored inverted echo sounders. The results show statistically high correlation between the in situ measurements at periods greater than 5 days and between the altimeter and in situ measurements at periods greater than 20 days. The rms difference between any two modes of observation is consistently between 2 and 3 cm. (Résumé d'auteur)

A comparison of vaccine efficacity and mortality during routine use of high-titre Edmonston-Zagreb and Schwarz standard measles vaccines in rural Senegal IRD
Aaby, Peter; Samb, Badara; Simondon, François; Knudsen, K.; Coll Seck, A.M.; Bennett, J.; Markowitz, L.; Wittle, H..
Vaccine efficacy and mortality in successive cohorts of children who routinely received either Edmonston-Zagreb high-titre (EZ-HT) or Schwarz standard (SW-STD) measles vaccines have been examined in a rural area of Senegal. The 2 vaccines were equally protective against measles infection (vaccination efficacy : EZ-HT 94 % ; SW-STD 93 %). Children who did not attend a scheduled session to receive measles vaccine had a higher mortality rate between 9 months and 2 years of age than did children receiveng either EZ-HT (mortality ratio [MR] = 1.81, 95 % confidence interval [CI] 1.06-3.08) or SW-STD measles vaccine (MR = 1.74, 95 % CI 0.95-3.21). Children of either sex vaccinated with EZ-HT had lower mortality than their equivalents who had not received any...

A method to assess the set time of the purse seiners in the Indian Ocean IRD
Marsac, Francis.
La durée des coups de filet effectués au moyen de 3 types de sennes qu'utilisent les thoniers dans l'Océan Indien, sont analysées et leurs efficacités respectives sont comparées. Les données ont été collectées à bord des senneurs français et ivoiriens (FI) par des observateurs scientifiques. En l'absence d'informations concernant les thoniers espagnols qui emploient un gréement particulier, l'efficacité de cet équipement peut être appréciée au travers des résultats obtenus par un senneur français qui en est pourvu. La relation entre le temps de sennage et la capture est linéaire, quelque soit le type de gréement. (D'après résumé d'auteur)
