Yes it still harmful because it is air pollution to your lungs. My kid's pediatrician used to tell me that I should change my clothes after smoking a cigarette and before I carry my baby.
In Scrum, a product backlog item (PBI, backlog item, or item) is a unit of work small enough to be completed by a team in one Sprint iteration. Backlog items are decomposed into one or more tasks. See also backlog effort estimation unit.
Polymer nanocomposites (PNC) consist of a polymer or copolymer having nanoparticles or nanofillers dispersed in the polymer matrix.These may be of different shape (e.g., platelets, fibers, spheroids), but at least one dimension must be in the range of 1â50 nm.These PNC's belong to the category of multi-phase systems (MPS, viz. blends, composites, and foams) that consume nearly 95% of plastics production.his affects the properties of the particles when they are reacting with other particles. Because of the higher surface area of the nano-particles, the interaction with the other particles within the mixture is more and this increases the strength, heat resistance, etc. and many factors do change for the mixture.
