The RAFOS System

The RAFOS float is a small neutrally buoyant subsurface order, which, like its big brother the SOFAR float, uses the deep sound (or SOFAR) channel to determine its position as a function of time. Whereas the SOFAR float transmits to moored receivers, the ∼12 kg glass pipe RAFOS float listens for accurately timed signals from moored sound sources to determine its position. The acoustic signal detection and norm of data are all handled by a CMOS microprocessor in the float. The data are recovered at the end of its mission when the float surface and telemeters its memory contents to Systeme Argos, a satellite-borne platform location and data collection system. Just a few sound sources provide navigation for an arbitrary number of floats

Northeast Folklore volume 1 numbers 1-4

The first ever issue of Northeast Folklore was published in the spring of 1958 under the editorship of Edward D. Ives (known as Sandy) and Bacil F. Kirtley through the Department of English at the University of Maine. The four editions that year were later bound into a single volume.

Genetic Resistance to Rhabdovirus Infection in Teleost Fish Is Paralleled to the Derived Cell Resistance Status

Genetic factors of resistance and predisposition to viral diseases explain a significant part of the clinical variability observed within host populations. Predisposition to viral diseases has been associated to MHC haplotypes and T cell immunity, but a growing repertoire of innate/intrinsic factors are implicated in the genetic determinism of the host susceptibility to viruses. In a long-term study of the genetics of host resistance to fish rhabdoviruses, we produced a collection of double-haploid rainbow trout clones showing a wide range of susceptibility to Viral Hemorrhagic Septicemia Virus (VHSV) waterborne infection. The susceptibility of fibroblastic cell lines derived from these clonal fish was fully consistent with the susceptibility of the parental fish clones. The mechanisms determining the host resistance therefore did not associate with specific host immunity, but rather with innate or intrinsic factors. One cell line was resistant to rhabdovirus infection due to the combination of an early interferon IFN induction - that was not observed in the susceptible cells - and of yet unknown factors that hamper the first steps of the viral cycle. The implication of IFN was well consistent with the wide range of resistance of this genetic background to VSHV and IHNV, to the birnavirus IPNV and the orthomyxovirus ISAV. Another cell line was even more refractory to the VHSV infection through different antiviral mechanisms. This collection of clonal fish and isogenic cell lines provides an interesting model to analyze the relative contribution of antiviral pathways to the resistance to different viruses

The deep drifter program.

An intrument for studies of subsurface and deep ocean currents which employs the ARGOS system to determine the pop-up point of the drifter at the end of its mission is described. The instrument is 2m long and weighs 12kg. The entire electronics package including the quad-helix antenna fits inside a standard 7.5cm ID glass pipe, which provides the flotation. In situ pressure and temperature information is collected with a CMOS microprocessor for later broadcast to ARGOS at the surface. The RF link at the surface is very reliable; even in heavy weather 50% of the transmissions are received correctly. Two subsurface tests were conducted successfully in the Gulf Stream: 7 days at 400m and 5 days at 1700m. -from STAR, 23(14), 198

The deep drifter-a simple tool to determine average ocean currents

An expensive drifter has been developed for studies of subsurface and abyssal currents. It uses an ARGOS radio transmitter to reveal its pop-up position at the end of a programmed period of submergence, which may last from days to months. Statistical significance of mean flow estimates is achieved through ensemble averaging a set of drift vectors, hence an emphasis on low cost. © 1983

Sensibilité du brochet (Esox lucius) à différents virus de salmonidés (NPI, SHV, NHI) et au rhabdovirus de la perche

Des alevins de brochet âgés de 10 jours à 2 mois ont été soumis à l'infection expérimentale par 4 souches de virus de salmonidés (NPI, NHI, SHV types 1 et 3) et par le rhabdovirus de la perche . Le virus de la NPI a provoqué une mortalité de 74% chez des alevins âgés de 10 jours , avec comme principaux signes cliniques une exophtalmie et un ballonnement abdominal consécutif à l'accumulation de l iquide . L'histopathologie a permis de retrouver les lésions pancréatiques habituelles chez les salmonidés , accompagnées d'une hépatite nécrosante remarquable et de lésions cardiaques. Les alevins âgés de deux mois ont parfaitement résisté à l'infection par la NPI. Les 4 rhabdovirus , y compris celui de la perche, ont provoqué des hémorragies souvent accompagnées d'exophtalmie , entraînant des mortalités comprises entre 40 et 70 % sur des alevins âgés de 1 à 2 mois. Ces résultats montrent ou confirment l'extrême réceptivité de l'alevin de brochet aux principaux virus des salmonidés , en y ajoutant le rhabdovirus de la perche
