Paratuberculosis, or Johne's disease, in cattle is caused by Mycobacterium avium subsp. paratuberculosis, which has recently been suspected to be transmitted through dust. This longitudinal study on eight commercial M. avium subsp. paratuberculosis-positive dairy farms studied the relationship between the number of cows with M. avium subsp. paratuberculosis antibody-positive milk and the presen...

Activities concern several aspects of digital film restoration, including the analysis of issues related to the problem, ranging from the kind of different defects, to their causes, and to methods and algorithms for their removal. Particular attention is given to some specific types of defects that can affect digital image sequences and to methodologies adopted for their management, devising ne...

This work was motivated by the need to better reconcile emission factors for fugitive dust with the amount of geologic material found on ambient filter samples. The deposition of particulate matter with aerodynamic diameter less than or equal to 10 microm (PM10), generated by travel over an unpaved road, over the first 100 m of transport downwind of the road was examined at Ft. Bliss, near El P...

At present, the exhaust gas temperature of coal-fired power plants is 125-150℃, and emission high-temperature flue causes loss excess heat wastes. For this kind phenomenon, waste recovery system researched designed, combined with combination a low-temperature economizer in plant Dezhou. The heater, through heater system, reduces coal consumption for generation, emissions, while reducing dust sp...

Intervention studies of cotton steaming to reduce biological effects of cotton dust. Previous exposure chamber studies had suggested that steaming cotton could reduce significantly the levels and the biological effects of cotton dust. Therefore an intervention study using a high capacity steamer was designed to test the effectiveness of this process in a single cotton mill. The mill population ...
