Contamination of folic acid assay medium with oleate led to a lag phase when Lactobacillus casei cultures were grown on folic acid but not when whole serum provided the folate source. This led to high assay values when using 20-hour incubation periods but satisfactory results were obtained after 48 hours' incubation. The addition of Tween 80 to the medium eliminated the lag phase and the assay ...

This paper presents early results of a (very) experimental implementation of the elliptic curve and stream cipher calculations of the Networking and Cryptography library (NaCl), on the TRS-80 Model I. Needless to say, the demonstration that such a library, which has been optimized for many modern platforms including leading edge desktops, servers and, recently, modern microcontrollers, is even ...

Analyses of National Highway Traffic Safety Administration’s Fatality Analysis Reporting System (FARS) and National Automotive Sampling System (NASS)/General Estimates System (GES) data from 2002 – 2006 revealed specific performance errors and combinations of driver, vehicle, and roadway/environmental characteristics associated with older drivers’ crashes at intersections. For subsets of the tw...

The subject of this paper, an improbable implementation of a recently standardized cryptographic hash function on a thirty-five-yearold microcomputer, may strike some as unusual and recreative at best. In the tedious discipline of the process, however, lessons were learned in implementation trade-offs for basic cryptographic primitives which may prove interesting in the current context of secur...
