Additive manufacturing (AM) has the advantages of fabricating complex models for application. In this study, cube structure with various porosity is manufactured by AM of selective laser melting (SLM). CAD software is used to create the micro porosity of sample models from 60 %∼80 %. The models are printed by Ti-6Al-4V powders. The morphology of the printed porous structures are examined by OM and...
A one-year surveillance project was conducted at a large tertiary hospital, which had extensive indoor renovation and extensive demolition/building at several nearby sites. This study collected viable fungi samples in the hospital every six days and analysed 74 duct dust samples for Aspergillus fumigatus mycelial asp f1 protein. Mean total fungi were 257.8cfu/m 3 outdoors, 53.2cfu/m 3...
