We construct a non-free but א1-separable, torsion-free abelian group G with a pure free subgroup B such that all subgroups of G disjoint from B are free and such that G/B is divisible. This answers a question of Irwin and shows that a theorem of Blass and Irwin cannot be strengthened so as to give an exact analog for torsion-free groups of a result proved for p-groups by Benabdallah and Irwin.

Fecal coliform bacteria cause water quality problems for many urban areas across the United States. The objective of this study is to determine if the Irwin Creek and Sugar Creek wastewater treatment plants, located near Charlotte in Mecklenburg County, North Carolina, contribute significantly to the fecal coliform concentrations in the creeks. Fecal coliform densities in the wastewater effluen...

OBJECTIVE Show how lunar catecholamine cardiomyopathy alone, exemplified by Neil Armstrong's single space walk, prior to exposure to inhalation of fine particulate matter, can trigger " Neil Armstrong Syndrome" or by Irwin with coronary, possibly hypertensive heart disease, and catecholamine cardiomyopathy. With space flight, invariably magnesium ion deficits, catecholamine elevations, vicious ...

VIDENCE has been presented in previous communications from this that the antigens in the serum of a species of doves (Pearlneck or Streptopelk chinensis), specific for that species as contrasted with either of two other species (Senegal, St. senegalensis, or Ring dove, St. risork), segregated in back-cross individuals in accordance with genetic expectation. Subsequent data have supported this f...
