The dental implant acts as a replacement for the root of a missing tooth. In turn, this artificial tooth root serves to hold a replacement tooth or bridge. Having a dental implant fused to the jawbone is the closest thing to mimicking a natural tooth because it stands on its own without affecting the nearby teeth and has great stability.
Oxygen sensor. An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. GÃ¼nter Bauman.
1 Growth over discrete intervals. 2  Rate of growth (lambda) is the ratio of population size at the end of one interval to population size at the end of the previous interval. 3  N(t+1) = N(t) * (lambda); N(t)=N(0) * (lambda) t. 4  r = log e (lambda) and lambda = e rt; when r = 0, lambda = 1 and population density is stable.
