The design, construction and calibration of a low-energy, low exposure-rate ionization chamber

Creator:: Clarke, Arthur Porter
Abstract:: A low-energy, low-exposure-rate, guarded-field ionization chamber system with a sensitive volume of approximately 1040 cm³ and an exposure-rate range from 60 mR/h to less than 0.5 mR/h was designed, constructed and calibrated. The calibration was effected by constructing and calibrating a 60 cm³ volume transfer chamber of similar design against...

A taxonomic study on myxobacteria isolated from fish

Creator:: Porter, Sook Hee
Abstract:: While the genus Cytophaga has been defined and classified on a morphological basis, knowledge of fresh water members of this group of myxobacteria is scanty. In the present study cultural and morphological characteristics were investigated in an attempt to classify a group of fresh water cytophaga. Microscopic examination revealed all...

The association of DNA with other cellular materials in Escherichia coli lysates

Creator:: Porter, Bruce Wallace
Abstract:: The association of other materials with DNA has been studied extensively in higher organisms and more recently in bacteria. However, investigation of these complexes in bacteria have for the most part been restricted to the study of a specific function this association may serve, or a specific kind of association....

The histopathological effects of larval trematodes on the hepatopancreas of Oxytrema siliqua (Gould)

Creator:: Porter, Clarence Alan
Abstract:: The histopathological and histochemical effects on the snail Oxytrema siliqua, caused by the larvae of Nanophyetus salmincola, have been studied. The parasite causes damage to the organ by increased pressure, active ingestion of the hepatic tubules, and by the increased burden placed upon the snail in disposing of the waste...

Analysis of the fit of women's custom-made pants

Creator:: Porter, Madeline Eleanor
Abstract:: Pants have become a seemingly necessary part of the average American woman's wardrobe and may be worn for nearly every occasion. However, many women have indicated that when conventional methods of construction were used for pants-making, the pants did not conform to their expectation of good fit. Observation showed that...

The morphology of the reproductive tracts of the Pacific Northwest pulmonates

Creator:: Porter, Clarence Alan
Abstract:: The morphology and taxonomic use of the reproductive tracts of some of the Pacific Northwest Pulmonates were studied. The snails examined were, Monadenia fidelis (Gray), Vespericola columbiana (Lea), Allogona townsendiana (Lea), Haplotrema sportella (Gould), and Haplotrema vancouverense (Lea). The length of the reproductive tracts of nine or more individuals of...

A study of the fatty acids and lipids of Clostridium botulinum type B

Creator:: Paterno, Visitacion Asi
Abstract:: The difficulties encountered in working with micro-quantities of lipids have been overcome by the advent of new and improved procedures in chromatography which have made possible better fractionation and identification. Bacterial lipids because of their different lipid pattern from other life forms have stimulated much interest. Studies have been made...

The lipids of spore types B, E, and F and vegetative cell types E and F of Clostridium botulinum

Creator:: Kimble, Charles E.
Abstract:: The primary purpose of this investigation was to characterize the lipids of the spores and vegetative cells of Cl. botulinum. A second purpose was to explore the possibility that lipids might serve as a means of differentiating the chiefly proteolytic Cl. botulinum type B from the nonproteolytic Cl. botulinum types...
