The mechanism behind attenuation of An3739 in outbred hamsters is unclear but may involve virus passage history in newborn hamster brains.
Damage rates of this magnitude are limited to a volume of ∼500 cm3 (attenuation in beam direction) behind a beam footprint of 20 × 5 cm2, so the high flux region of the module is contained in a flat faced, cuboid volume of 5.6 cm depth.
The availability of this cDNA clone will allow examination of the molecular mechanisms behind FMDV virulence and attenuation, which might in turn allow the production of second-generation, genetically engineered FMDV vaccines.
The availability of the first cDNA clone of DHV-1 will allow examination of the molecular mechanisms behind DHV-1 virulence and attenuation, which could in turn lead to the production of second-generation, genetically engineered DHV-1 vaccines.
Moreover, any pixel behind an area of high attenuation reaching a predefined minimum signal-to-noise-ratio (SNR) is automatically excluded for further analysis.
This paper studies the attenuation of stress-waves in a concrete medium behind a rectangular inclusion of expanded polystyrene (EPS) geofoam with different dimensions.
The coupled evaluation of the radiographic images and the thermophysical properties of water have shown that the main driving force behind the decrease of the neutron attenuation is the decreasing water density as the bulk-fluid temperature increases.
Attenuation of the inflammatory response is the apparent mechanism behind lidocaine-induced analgesia [ 49]; however, there was no difference between the two groups for the Von Frey filament test (Table 3), suggesting that at least in this study, either hyperalgesia was not affected by TA or the number of animals was not sufficient to show differences between the groups.
The transmission through an object with thickness d can be described by the general attenuation law between the beam intensities in front of and behind the object, I0 and I, respectively.
