SynopsisThe absorption of ultraviolet light by a film of sunscreen product on the surface of the skin is considered from a theoretical standpoint. It is apparent that Beer‐Lambert's Law would predict protection factors in excess of the actual factors by many orders of magnitude.

Respirator protection factors: part II — protection factors of supplied-air respirators
American Industrial Hygiene Association Journal, 1980Protection Factors provided by 25 NIOSH approved supplied-air respirators were determined while the devices were worn by a panel of test subjects anthropometrically selected to represent adult facial sizes. Polydispersed DOP aerosol was used for respirator fit tests on continuous flow, demand, and pressure-demand respirators. Based on facepiece leakage

Protective factors and risk factors
Organizational Psychology Review, 2016Dyadic work relationships are fundamental to effective organizing and are a means by which individuals find meaning at work. Such relationships may contain latent competencies with the potential to infuse the dyad with purpose. Meaningful dyadic relationships depend on the dyad’s ability to be resilient to within-dyad adversity.

Caries-Protective Factors in Saliva
Advances in Dental Research, 1994Saliva influences caries attack mainly by its rate of flow and by its content of fluoride. The salivary flow rate influences to a high degree the rate of oral and salivary clearance of bacterial substrates included in foods and snacks. This influence is site-dependent.

Beyond sun protection factor testing
International Journal of Cosmetic Science, 2004SynopsisUltraviolet radiation in sunlight produces a range of acute and chronic adverse effects on the skin including sunburn, photosensitivity rashes, immunosuppression, photoageing and carcinogenesis. Sunscreens aim to provide protection, but standard testing procedures primarily involve assessment of ability to protect against acute erythema, as ...

Variability in Respiratory Protection and the Assigned Protection Factor
Journal of Occupational and Environmental Hygiene, 2004The workplace protection factor (WPF) for a given respirator wearer shows substantial variability from wearing to wearing; this variability is commonly assumed to be lognormal in nature. Further, when multiple WPFs are measured for each of multiple wearers, the aggregated WPFs appear to follow a lognormal distribution.
