Hydroxyl has been recently observed for the first time in the Venus atmosphere with the VIRTIS spectrometer on board the Venus-Express spacecraft. The (1-0) around 2.81 microns and the (2-0) around 1.46 microns transitions have been detected. The intensity of the two emissions are respectively about 55 and 480 times less intense than the (0-0) oxygen transition (Piccioni et al, A&A, 2008). The possible chemical reactions which can produce hydroxyl on Venus involve O3 and HO2, with the former being the most probable, and hence OH can be used to indirectly infer the ozone distribution on Venus. VIRTIS data in limb mode observation were analyzed to derive the mean distribution of hydroxyl in the night side of Venus and the results are presented here. The typical peak altitude of the two emissions is set at 95-96 km in limb view, a few km lower than the oxygen emission at 1.27 um due to the transition (0-0). The peak altitude of the latter typically occurs at 97-98 km height. The OH full width at half maximum is in average about 7 km, and sometimes higher. The mean map of (1-0) hydroxyl distribution around 2.81 microns shows a maximum of emission of about 130 kR at about 1h local time. The study of the (2-0) hydroxyl distribution at around 1.46 microns results more difficult due to its weak intensity. [less ▲]

Hydroxyurea is an anticancerous product, used recently in the treatment of HIV-1 infection thanks to its inhibitory action in viral replication, potentialization of the nucleosides activity (particularly ddI or didanosine) and its cytostatic properties on CD4 and CD8 lymphocytes. Many studies showed its efficiency, as further drug, in initial regimen of a tritherapy (containing ddI) and salvage therapy. The dosage of 500 mg bid seems tolerated well by adults, and 20 mg/kg by children. Long-term tolerance remains unknown. With ddI, it could be proposed in developing countries. [less ▲]

Several bacterial indicators are used to evaluate the hygiene of the meat slaughtering process. The objectives of this study were to assess the Belgian baseline of hygienic indicators and the relationship between the indicators and zoonotic agents, in order to establish hygiene indicator criteria for carcasses and meat of beef, pork and poultry. The study used the results from the official Belgian surveillance plan from 2000 to 2003, which included the monitoring of counts for E. coli (ECC), Enterobacteriaceae (EC), aerobic colonies (ACC) and Pseudomonas. The sampling method was the wet and dry swabbing technique for beef and pork carcasses, and neck skin excision for chicken and layer carcasses. The 75th and 95th percentiles of ECC were –0.20 and 0.95 log cfu/cm2 for beef carcasses, 1.20 and 2.32 log cfu/cm2 for pork carcasses, and 4.05 and 5.24 log cfu/g for chicken carcasses. The aerobic colony counts were between 2.1 and 4.5 log cfu/cm2 or /g higher than those of ECC for cattle, pork and poultry. For beef and pork carcasses, a significant correlation between ECC, EC and ACC was shown between each parameter. ECC (for pork and beef samples), and EC (in pork carcasses) were detected at significantly higher levels in samples contaminated with Salmonella. In poultry samples, ECC were in general higher for samples containing Salmonella or Campylobacter. This study showed that E. coli may be considered as a good indicator for enteric zoonotic agents such as Salmonella for beef, pork and poultry, and Campylobacter in poultry meat samples. [less ▲]

Coatings are designed to protect concrete against environmental aggression. Water is one of the aggressive parameters able to deteriorate the concrete structure. The objectives of this paper are to present the effects of water (i) during application of coating on the concrete substrate and (ii) pull-off test. Semi-permanent moisty state produced by absorption from the uncoated face, total immersion or diffusion of water from the back face of the substrate are analysed. Water vapour diffusion and influence of hydrophobic treatment are also investigated. A classification based on increasing influence of the tests and application conditions on adhesion is proposed and clearly points out the negative effect of capillary action from the uncoated face.

This paper studies the specific hygrothermal behavior of Lime-Hemp concretes through analysis of non-linear coupled heat and moisture transfer using a research model. Three compositions were studied, varying the type of binder. First Moisture Buffer Value determination tests are lead experimentally using the NORDTEST protocol. These dynamic experiments, which reveal the moisture storage and exchange capacity together with latent heat effects, are then modeled using a set of partial differential equations. The reduction of humidity buffering capacity induced by hydraulic binder incorporation is properly evaluated and the hygrothermal parameters can be assessed by inverse modeling. [less ▲]

Hygroscopic building materials can affect the indoor air by exchanging moisture with it and buffering the ambient humidity variations. The Nordtest protocol and the concomitant Moisture Buffer Value (MBV) parameter definition has been one of the first attempt to characterize this moisture regulation performance. This paper present an attempt to confront this well-established experimental protocol with a mathematical model implemented in the Comsol multiphysics solver. The power of the simulation will be showed with a good correlation between the modelling and the experimental phase for the MBV determination of a lime-hemp concrete bloc. [less ▲]

Most reports published in the field of forensic entomology studies are focused on Diptera pattern colonization and are neglecting Hymenoptera succession. Hymenoptera are part of the entomofaunal colonization of a dead body as parasitoids of fly pupae. However, one should consider Hymenoptera parasitoids in a forensic entomology context to evaluate the time of death. Blowflies parasitoids may indeed be of particular importance as their time of attack is often restricted to a small, well-defined window of developmental time of the insect host. Because these parasitoids also interfere with developmental times of colonizing Diptera, a better understanding of their ecology is needed. [less ▲]
