Single curved surfaces are composed of consecutive ...

However, a class of greatest importance for us, that of non-singular Riemann surfaces, is de ned by the following property: 1.5 Moral de nition: A Riemann surface Sin C2 is non-singular if each point (z 0;w 0) has the property that either the projection to the z-plane
GUIDANCE FOR CLEANING AND DISINFECTING
www.cdc.govMost surfaces and objects will just need normal routine cleaning. Frequently touched surfaces and objects like light switches and doorknobs will need to be cleaned and then disinfected to further reduce the risk of germs on surfaces and objects. • First, clean the surface or object with soap and water.
Roughness measurements of stainless steel surfaces
www.worldstainless.org5 ROUGHNESS MEASUREMENTS OF STAINLESS STEEL SURFACES Summary Although Ra values are commonly used to describe surfaces, the limits of this indicator should not be forgotten. Also the notation is important: “Ra ≤ 0.5 µm”, for instance, does not have the same meaning as “Ra max 0.5 µm”.Surface designations such as “2B”
Allowed Detergents and Sanitizers for Food Contact ...
www.ams.usda.govSANITIZE: Sanitizers are applied to cleaned surfaces to insure that the surface is free of pathogenic microbes. The sanitizing step is a mandated part of most state and federal food safety protocols for food contact surfaces. Sanitizers merit more scrutiny than cleaners in an organic process because some sanitizers are designed to

ucfoodsafety.ucdavis.eduIn addition to sanitizing food contact surfaces, chlorine bleach solutions may be used for sanitizing raw fruits and vegetables during the washing or peeling process. The federal regulations that apply differ slightly from those for sanitizing solutions given above. The regulations (21 CFR Part 173) specify two conditions for the permit-
