Control of nosocomial salmonellosis and implementation of effective biosecurity programs to limit the risk of this disease continue to be a challenge in equine hospitals. Monitoring programs for detection of fecal shedding of Salmonella serovars is an effective tool to identify both nosocomial infection and colonization and to determine when changes in biosecurity programs may be necessary. Aut...

The tracheobronchial tree delivers and distributes air within the lung. Normally it provides a low resistance to airflow. Airway smooth muscle, the mucociliary system, the bronchial circulation, and cough provide neurally mediated protection of the lung from environmental challenges. Disease involves an exaggerated response of these mechanisms so that the airways become obstructed, distribution...

Software reuse is the use of existing software artifacts and knowledge to construct new software. Systematic reuse has always been a major goal in software engineering since it promises large gains in productivity, quality, and time-to-market reduction. One of the main reasons software reuse has not been systematically practiced is due to the lack of education: In a survey collected from 113 re...
