Study of SARS Transmission Via Liquid Droplets in Air
Microscale liquid droplets could act as the SARS carriers in air when released from an infected person through breathing, coughing, or sneezing. In this study, a dynamic model has been built to quantitatively investigate the effect of the relative humidity on the transport of liquid-droplets in air using coupled mass transfer and momentum equations. Under higher relative humidity, the exhaled liquid droplets evaporate slowly. Larger droplets fall faster, which could reduce the probability of the droplets inhalation. This may be one of the most important factors that influence the SARS transmission in air.
【Objective】To explore clinical characteristics and treatment of the solitary fibrous tumor of pleura(SFTP).【Methods】Clinical records of 10 SFTP patients who had received surgical operation during the period of 2003 to 2009 in our hospital.【Results】All patients results were fine after operation,one patient had recurrence of lung.Immunohistochemical results showed that the CD34 and Vimentin were positive expression in all cases,the desmin was negative in all cases.【Conclusion】The surgical operation is the best method for SFTP currently.The immunohistochemical exam plays an important role in the diagnosis of SFTP.
