The body of information in this paper is directed to specialists in industrial health and safety, and air and water pollution, who need quantitative data on the odor thresholds of potentially hazardous chemical vapors and gases. The literature, largely unorganized, has been reviewed for 214 compounds and condensed into tables based on consistent units. Data on the volatility, solubility, ioniza...

OBJECTIVE Clinical and epidemiological research suggest that bone mineral density (BMD) in women is shaped by various reproductive factors such as parity and lactation patterns. However, the extent of these effects on BMD remains unclear because of contradictory findings and a focus on industrialized populations. Because fertility patterns in these groups are vastly different than those of wome...

DemographyofHabrobraconhebetor(Say)(Hymenoptera:Braconidae)on twopyralid host species [Galleria mellonella (L.) and Ephestia kuehniella Zeller] (Lepidoptera: Pyralidae) was studied at 28 C in the laboratory. Data were analyzed based on an age-stage, two-sex life table, to take both sexes and variable development into consideration. The intrinsic rate of increase (r), Þnite rate of increase ( ),...

Among the hyphomycetous endoparasites destructive to eelworms that abound in slowly decaying plant materials, as well as in agar plate cultures earlier inoculated with partly decomposed vegetable detritus, Harposporium anguillulae Lohde emend. Zopf (1888) is observed much more frequently than allied forms. In seeking an explanation for this more frequent occurrence it would seem highly signific...
