To determine homogeneity each filter was inserted in a parallel beam of light. Next, a picture was taken from 2.2 m distance. The homogeneity was assessed in comparison with the reference picture, which wasn’t ideal due to practical difficulties. We would like to emphasize that fact at the ...

Filter facepiece respirators (FFR) models are comprised of different materials and numbers of layers; therefore, FFR models yield different log-removal values following UV treatment. The respirator layer that was selected for inoculation also impacted the disinfection efficacy of UV-C exposure. Additio...
(Fig.5a). Homogeneity test for variances and mean comparison showed significant differences between the tanned RHE and all in vivo measurements (p < 0.001), even if the approximated ITA of 46° for the RHE models would correspond to a “light” skin, similar to the subject with an ...
In comparison, degradation and mineralization of pNP in a single PBR process (without pretreatment) was found to be 84.7 % and 47.2 %, respectively, during 30 h biotreatment. Coupling the fluidized bed UVC/VUV with the PBR attained complete biodegradation of the residual pNP within 1...
In comparison, the corresponding non-structured surfaces could remain superhydrophilic for <4 days (Fig. 4c). Moreover, after 36 days, the ultimate WCAs of the nanostructured CMC- and GA-coated surfaces (<20°) were far less than those of non-structured surfaces (~50°), indicating that ...
Finally, a light trap having fibers will filter clumped biological material, removing the difficulties that can arise with killing this type of biological material with UV radiation. One embodiment of a porous flux multiplying light trap is shown in FIGS. 3B and 3C. The overall end or exit ...
