The ablation of poly(ethylene terephthalate) (PET) by Ar-F laser radiation has been studied at different fluences for amorphous and semicrystalline samples scanning electron microscopy (SEM) etch-depth measurements. surface structure created on PET interpreted as resulting mainly from a difference in the etch rate—and not threshold—between PET. SEM pictures clearly show melting high fluence (≥80 to 100 mJ/cm2) below that value. UV etching is proposed quick easy method observing crystalline...
The importance of biosecurity as a strategy to prevent and control infectious diseases has increased substantially over the last few decades. Several studies have reported low implementation level measures (BSM), particularly in cattle farms. In addition, recent study demonstrated that farmers are well aware recommended BSM recognize them more effective (in terms time costs) than treatment for disease. Therefore, other factors must be considered when it comes understanding decision-making...
Bovine viral diarrhea virus (BVDV) is a common pathogen of cattle herds that causes economic losses due to reproductive disorders in breeding and increased morbidity mortality amongst infected calves. Our objective was evaluate the impact BVDV spread on productivity beef cow-calf herd using stochastic model discrete time accounted for (1) difference transmission rates when animals are housed indoors versus grazing pasture, (2) external risk disease introductions through fenceline contact...
Atomic hydrogen is commonly used to clean GaAs surfaces. The goals of this work are optimize the cleaning process and control surface reactions in order avoid decomposition GaAs. Chemically polished (001) surfaces have been cleaned by thermally generated atomic analyzed sensitive techniques. We propose an optimal involving two exposures. first one at room temperature etches As oxides. second 300 °C completes reduction Ga demonstrate that variations ionization energy, function, Fermi level...
GaAs (100) covered with its native oxides is exposed to increasing doses of low energy atomic hydrogen in order test the possibility using it for surface cleaning at moderate temperatures. Hydrogen molecules are dissociated a hot filament, and samples room temperature 300 °C between 100 L kL H2. The chemical modifications characterized by ultraviolet x-ray photoelectron spectroscopies. Exposures contribute clean surfaces both At temperature, As completely desorb below 30 kL. substrate not...
We have studied the interface formation between Sb(111) surfaces and evaporated aluminum with photoemission using synchrotron radiation. Energy distribution curves were measured from Al 2p Sb 4d core levels valence band. A curve-fitting procedure was applied to core-level spectra in order decompose peaks into individual components. model calculation performed explain intensity variation of different show that a two-dimensional layer AlSb is formed clusters grow on top as soon fraction...
Beef cow-calf farming systems are assumed to be resilient biological disturbances that induce variations in herd demography; however, this hypothesis has not been fully investigated date. Modeling is an interesting approach study system resilience and evaluate the impact of disturbances, taking into account interactions between components, including variability management practices. Our objective was beef fertility mortality using a modeling approach. We studied direct effect demographic...
In the last few years, CPM developed a first generation of charging model for coke ovens to improve uniformity oven filling and reduce emissions. A new has been recently built simulate all kinds process with 3, 4 or 5 holes obtain more reliable representation levelling operation. More particularly, coal accumulation in each compartment leveller bar is represented, order have better idea gas free space during By using this model, it now possible suppress operation constant uniform profile at...
Bovine viral diarrhoea (BVD) remains an issue despite control programs implemented worldwide. Virus introduction can occur through contacts with neighbouring herds. Vaccination locally protect exposed However, virus spread depends on herd characteristics, which may impair vaccination efficiency. Using a within-herd epidemiological model, we compared three French cow-calf farming systems named by their main breed: Charolaise, Limousine, and Blonde d'Aquitaine. We assessed strategies of...
La qualification sanitaire vise à établir de manière objective et fiable le statut d'un animal ou ensemble d'animaux au regard d'une maladie infectieuse. Concevoir une repose sur des connaissances biologiques concernant l'agent pathogène, ses voies transmission les moyens détection la maladie. Les modèles mathématiques outils statistiques probabilistes permettent d'intégrer ces tout en prenant compte l'incertitude variabilité données biologiques. sciences humaines apportent un éclairage...
