Although the biological occurrence of 5'-methylthioadenosine
(MTA) and 5-methylthioribose (MTR) were recognized more than a half
century ago, very little light has been cast on the physiologic significance
of either substance. My studies were designed to extend
our knowledge of the metabolism of MTA and to determine if this pathway...
A dynamic approach to the Bayesian theory of sampling inspection
by attributes for the single sampling case is presented. A model is
developed which assumes a sequence of lots of equal known size and
lots generated by a process operating in a random manner. The model
also assumes constant associated...
A common problem in postal surveys of human populations
arises when some of the sampled people fail to respond to the questionnaire.
The problem is that the answers provided by the respondents
may not be typical of the answers the nonrespondents would
provide if these had been solicited more successfully....
A Bayesian approach to the analysis of a two-phase linear
regression model is given. It is assumed that the regression model is
continuous at the change point. The likelihood function is expressed
in a form which explicitly contains the continuity restriction. The
natural conjugate prior distribution for the likelihood function...
Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as
the P protein of the glycine decarboxylase complex (GDC)....

populations; breeding studies; physiological and phenological
investigations; cytological studies; ecological
studies...
Scientists in the biological sciences need to retrieve information from a variety of data collections, traditionally maintained in SQL databases, in order to conduct research.
