Some Improvements To Turner's Algorithm For Bracket Abstraction, Martin W. Bunder
Some Improvements To Turner's Algorithm For Bracket Abstraction, Martin W. Bunder
Faculty of Engineering and Information Sciences - Papers: Part A
A computer handles A-terms more easily if these are translated into combinatory terms. This translation process is called bracket abstraction. The simplest abstraction algorithm-the (fab) algorithm of Curry (see Curry and Feys [6])-is lengthy to implement and produces combinatory terms that increase rapidly in length as the number of variables to be abstracted increases.
Evaluation Of Dna Probes For Detection Of Shiga-Like-Toxin- Producing Escherichia Coli In Food And Calf Fecal Samples, Mansour Samadpour, John Liston, Jerry E. Ongerth, Phillip I. Tarr
Evaluation Of Dna Probes For Detection Of Shiga-Like-Toxin- Producing Escherichia Coli In Food And Calf Fecal Samples, Mansour Samadpour, John Liston, Jerry E. Ongerth, Phillip I. Tarr

The use of DNA probes for Shiga-like toxin I (SLT-I) and SLT-II for detection of SLT-producing Escherichia coli (SLTEC) in foods and calf fecal samples was evaluated. Enrichment cultures were prepared from food or fecal samples. Colonies formed by plating of enrichment cultures were probed for SLTEC by colony hybridization. Alternatively, enrichment cultures were analyzed for SLTEC presence by dot blot. The lowest detected concentration of SLTEC in sample homogenates inoculated with E. coli 0157:H7 corresponded to 1.3 CFU/g of sample. Of the 44 food samples and 28 fecal samples from dairy calves tested by the colony hybridization method, 4 …

Western immunoblot analysis of aqueous extracts of feces obtained from five giardiasis patients and from experimentally infected gerbils (Meriones unguiculatus) with rabbit antiserum to Giardia lamblia cysts has revealed antigens of three molecular weight groups. A stepladderlike, evenly-spaced set of strongly reactive antigens (darkest at a molecular weight [m.w.] of 55,000 to 70,000) appeared in the gerbil feces from day 4 (first experiment) or day 2 (second experiment) and lasted to about day 7 but disappeared completely by day 8 and did not reappear later. These antigenic bands were seen in gerbils infected with two isolates of G. lamblia. These …
