Flow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...

We wish to respond to two recent articles highlighting a decline in the frequency of bedside teaching and advocating a return to this traditional clinical education set piece [1, 2] We agree with the assertion that bedside teaching has, in the past, proved to be an important form of clinical education through which learners gain professional, communication, physical examination and reasoning sk...
متن کاملHow many hospital beds?
For many years, average bed occupancy level has been the primary measure that has guided hospital bed capacity decisions at both policy and managerial levels. Even now, the common wisdom that there is an excess of beds nationally has been based on a federal target of 85% occupancy that was developed about 25 years ago. This paper examines data from New York state and uses queueing analysis to e...
متن کاملBlocked Clause Decomposition
We demonstrate that it is fairly easy to decompose any propositional formula into two subsets such that both can be solved by blocked clause elimination. Such a blocked clause decomposition is useful to cheaply detect backbone variables and equivalent literals. Blocked clause decompositions are especially useful when they are unbalanced, i.e., one subset is much larger in size than the other on...
