Long drops in free fall

Acidogenic Potential of “Sugar-Free” Cough Drops

A patient presented with extensive marginal ditching around restorations recently placed during whole-mouth rehabilitation. The patient was not xerostomic and was otherwise normal except for the self-reported excessive use of "sugar-free" cough drops sweetened with sorbitol and Isomalt® (an equimolar mix of glucosyl-mannitol and glucosylsorbitol). This prompted an in vitro investigation to dete...

Free fall and cellular automata

Three reasonable hypotheses—homogeneity in time and space, bounded velocity of propagation of information, and bounded density of information—lead to the thesis that physical phenomena can be described and simulated with cellular automata. This implication has in fact been formalized into a theorem both in the classical [6] and the quantum case [1], albeit in flat space. Further evaluating this...

Medicare's reputation in free fall before budget.

Radar observations of individual rain drops in the free atmosphere.

Atmospheric remote sensing has played a pivotal role in the increasingly sophisticated representation of clouds in the numerical models used to assess global and regional climate change. This has been accomplished because the underlying bulk cloud properties can be derived from a statistical analysis of the returned microwave signals scattered by a diverse ensemble comprised of numerous cloud h...

Some Aspects of Free Fall Simulation

This paper deals with motion of a falling body in a quiescent fluid. The objective of first part is to give some mathematical analysis of free fall and to introduce the mathematical model of this problem. We show how to solve problems with domain which is apriori unknown and changes in time. We also present equation of motion with rotation and its solution and at the end some numerical results....
