Between October 1985 and June 1989, most active duty US Army soldiers were screened for human immunodeficiency virus (HIV) antibody. Of 648,032 screened soldiers in this analysis, 1,588 were HIV-antibody positive. In a multivariate analysis, correlates of positivity included: age [Adjusted Odds Ratios (ref less than 20 years) = 20-24 years, 3.7; 25-29, 9.3;(More)
Background: College students experience weight gain that can contribute to serious health issues. Health education efforts with college students are increasingly utilizing new technologies. Smartphone applications (apps) in particular are growing in popularity and use in all young adults. Purpose: Formative research was conducted to describe how college(More)
The H ion concentration of the culture medium is now recognized as being an important factor in the growth of all classes of plants. In certain special cases this may even become the limiting factor for growth. However, in experiments with higher plants growing in soils of different pH values a correct interpretation of results is difficult, because it is(More)
The authors conducted a population-based study to attempt to estimate the effect of human immunodeficiency virus type 1 (HIV-1) seropositivity on Armed Services Vocational Aptitude Battery test scores in otherwise healthy individuals with early HIV-1 infection. The Armed Services Vocational Aptitude Battery is a 10-test written multiple aptitude battery(More)

The data obtained in these experiments indicate clearly that unless the necessary precautions are taken to keep the iron of the culture medium in solution the results obtained by varying the H ion concentration will not represent the true effect of this factor on growth. The availability of iron in nutrient solutions has been the subject of numerous recent(More)
