As a part of the theme of this session, which is concerned with the role of highways in the national transportation scene, your program committee wanted to have discussed some of the administrative aspects of highway transportation. In particular, it desired that comment be made on the problem of “Maintaining Effective Highway Adminis tration.” This is, I assume, subject to interpretation. If ...

There are several different “types” of viscosities that one may encounter in fluid dynamics. First, we differentiate between the kinematic and dynamic viscosities, referred to by symbols ν and μ or η. They are related via the density of the medium, with ν = η/ρ. The units of dynamic viscosity are Poise or Pa.s and the dimensions are [ML−1T−1]. Kinematic viscosity has dimensions of [L2T−1] and i...

Screens in mosaicDrosophila tissues that use chemical mutagenesis have identified many regulators of growth and patterning. Many of the mutant phenotypes observed were contingent upon the presence of both wild-type and mutant cells in the same tissue. More recently, large collections of RNAi lines or cDNAs expressed under Gal4/UAS control have been used to alter gene expression uniformly in spe...
