Shielding Effectiveness
Found 9 free book(s)Radio Frequency Interference (RFI) Shielding Principles
www.kriegerproducts.comShielding Effectiveness (SEdB), or attenuation (dB). Shielding effectiveness can be calculated using the following equations. SE dB = 20log H 1 /H 2 (dB) Where: H 1 is the Magnetic Field (µA/m or µT) detected without a shield H 2 is the Magnetic Field (µA/m or µT) detected with a shield between the noise source and sensitive environment SE ...
Understanding Shielded Cable - Mouser Electronics
www.mouser.comAs shown in Figure 2, this presents shielding effectiveness superior to either approach alone. Increasing the performance of the Supra-Shield design is the unique triple laminate aluminum/polyester/aluminum foil tape. This tape increases shielding effectiveness through reduced shield resistance and is in contact with a drain wire to facilitate

Inactivation (disinfection) processes
www.who.intEffectiveness of chlorine against protozoa Protozoan cysts such as Entamoeba histolytica and Giardia lamblia are highly resistant to chlorine disinfection and may require prolonged contact times at high chlorine residuals (2–3 mg/l) to achieve 99.9% (3-log) inactivation. Clark, Read & Hoff (1989) have described a mathematical model for Giardia
