We study numerically, using the Mie theory, light transmission through a multiply scattering medium composed of collection uncorrelated, optically inactive spherical particles. The characteristic length over which plane-wave field is depolarized depends on whether it initially linearly or circularly polarized and size In containing particles small compared to wavelength (Rayleigh regime), depolarization for incident found exceed that light, while opposite true in large (Mie regime).

Abstract Wild birds share with humans the capacity for moving fast over large distances. During migratory movements, carry pathogens that can be transmitted between species at breeding, wintering, and stopover places where numerous of various are concentrated. We consider area Camargue (southern France) as an example to highlight how ad hoc information already available on birds’ abundance, diversity help assess introduction transmission risk birdborne diseases in western Mediterranean...
To identify the mosquito species able to sustain transmission of West Nile Virus (WNV) in Camargue region (the main WNV focus southern France), we assessed vector competence Culex modestus and pipiens, most abundant bird-feeders, Aedes caspius, mammophilic occasionally found engorged with avian blood. Female mosquitoes were exposed infectious meal (10(10.3) plaque forming units (PFU)/mL) by membrane feeding, hold at 26 degrees C. After incubation period, disseminated infection was detection...
The European Commission requested EFSA to compare the reliability of wild boar density estimates across EU and provide guidance improve data collection methods. Currently, only EU-wide available are hunting data. Their methods should be harmonised comparable predictive models for density. These could validated by more precise data, collected at local level e.g. camera trapping. Based on practical theoretical considerations, it is currently not possible establish thresholds that do allow...
Millions of workers are exposed to carcinogenic polycyclic aromatic hydrocarbon (PAH) mixtures. The toxicity PAH mixtures is variable and depends on the composition mixture, which related emission sources. Although several indicators exist, cancer risk estimation associated with occupational exposure PAHs poorly known.To assess lung in industries using atmospheric concentrations benzo[a]pyrene (BaP) as a proxy.A total 93 groups belonging 9 were investigated. Eight found literature compared...
Rift Valley fever (RVF) is a vector-borne disease transmitted by broad spectrum of mosquito species, especially Aedes and Culex genus, to animals (domestic wild ruminants camels) humans. endemic in sub-Saharan Africa the Arabian Peninsula, with periodic epidemics characterised 5-15 years inter-epizootic periods. In last two decades, RVF was notified new African regions (e.g. Sahel), occurred more frequently low-level enzootic virus circulation has been demonstrated livestock various areas....
The AGRI committee of the European Parliament requested EFSA to assess welfare rabbits farmed in different production systems, including organic production, and update its 2005 scientific opinion about health kept for meat production. Considering reproducing does, kits growing rabbits, this focusses on six housing namely conventional cages, structurally enriched elevated pens, floor outdoor/partially outdoor systems systems. To compare level rabbit categories, impact scores 20 consequences...
In the framework of its Farm to Fork Strategy, Commission is undertaking a comprehensive evaluation animal welfare legislation. The present Opinion deals with protection cattle (including calves) during transport. Welfare transport by road main focus, but other means are also covered. Current practices related different stages (preparation, loading/unloading, transit and journey breaks) described. Overall, 11 consequences were identified as being highly relevant for based on severity,...
This Scientific Opinion considers the welfare of domestic fowl (Gallus gallus) related to production meat (broilers) and includes keeping day-old chicks, broiler breeders, chickens. Currently used husbandry systems in EU are described. Overall, 19 highly relevant consequences (WCs) were identified based on severity, duration frequency occurrence: ‘bone lesions’, ‘cold stress’, ‘gastro-enteric disorders’, ‘group ‘handling ‘heat ‘isolation ‘inability perform comfort behaviour’, exploratory or...
This Scientific Opinion addresses a European Commission's mandate on the welfare of dairy cows as part Farm to Fork strategy. It includes three assessments carried out based literature reviews and complemented by expert opinion. Assessment 1 describes most prevalent housing systems for in Europe: tie-stalls, cubicle housing, open-bedded with access an outdoor area. Per each system, scientific opinion distribution EU assesses main strengths, weaknesses hazards potentially reducing cows. 2...
The dynamics of electron transfer in a non-Debye solvent is described by multidimensional Markovian reaction-diffusion equation. To highlight differences with existing approaches the simplest possible context, irreversible outer-sphere reaction biexponential energy-gap autocorrelation function, Δ(t), studied detail. In Debye solvent, Δ(t)=exp(−t/τL) and rate can be rigorously expressed as an explicit functional exp(−t/τL). It has been suggested that exact found replacing exp(−t/τL)...
After 35 yr of disease absence, West Nile virus (family Flaviviridae, genus Flavivirus, WNV) circulation has been regularly detected in the Camargue region (southern France) since 2000. WNV was isolated from Culex modestus Ficalbi, which considered main vector southern France after horse outbreaks 1960s. Recent transmissions outside Cx. distribution suggested existence other vectors. To study potential vectors, horse- and bird-baited traps human landing collections mosquitoes were carried...
Background Leptospirosis is a worldwide zoonotic bacterial disease caused by infection with leptospires. in humans and livestock an endemic epidemic Thailand. Livestock may act as reservoirs for leptospires source human infection. Methodology/Principal findings Data on leptospirosis (Buffaloes, Cattle, Pigs) species during 2010 to 2015 were analyzed. Serum samples examined using Microscopic Agglutination Test (MAT) identify antibodies against Leptospira serovars cut-off titer ≥ 1:100. The...
The killing of pigs for human consumption (slaughtering) can take place in a slaughterhouse or on farm. processes slaughtering that were assessed welfare, from the arrival until their death, grouped into three main phases: pre-stunning (including arrival, unloading truck, lairage, handling and moving pigs); stunning restraint); bleeding. Stunning methods categories: electrical, controlled atmosphere mechanical. Twelve welfare consequences be exposed to during slaughter identified: heat...
Abstract Human mobility plays a crucial role in the temporal and spatial spreading of infectious diseases. During past few decades, researchers have been extensively investigating how human affects propagation However, mechanism shaping spread epidemics is still elusive. Here we examined impact on disease by developing individual-based SEIR model that incorporates mobility. We considered influenza two contrasting countries, namely, Belgium Martinique, as case studies, to assess specific...

Abstract Several vaccines have been developed against highly pathogenic avian influenza (HPAI), mostly inactivated whole-virus for chickens. In the EU, one vaccine is authorised in chickens but not fully efficacious to stop transmission, highlighting need tailored diverse poultry species and production types. Off-label use of possible, effectiveness varies. Vaccines are usually injectable, a time-consuming process. Mass-application outside hatcheries remain rare. First vaccination varies...
Abstract Selecting appropriate diagnostic methods that take account of the type vaccine used is important when implementing a vaccination programme against highly pathogenic avian influenza (HPAI). If effective, decreased viral load expected in samples for diagnosis, making molecular with high sensitivity best choice. Although serological can be reasonably sensitive, they may produce results are difficult to interpret. In addition routine monitoring, it recommended conduct isolation, genetic...
