The effects of univalent cations on the inductive formation of nitrate reductase

Creator:: Nitsos, Ronald Eugene
Abstract:: An investigation was undertaken to determine whether potassium is indeed necessary for the in vivo synthesis of a specific protein. The effects of univalent cations on the inductive formation of nitrate reductase and on the level of activity of representative non-adaptive enzyme are presented. Cultures of Neurospora crassa were grown...

Dose to the female breast from nuclear medicine and diagnostic radiology

Creator:: Patel, Aarti
Abstract:: There has been increased concern about radiation dose to the female breasts, with approximately 200,000 new breast cancers being diagnosed each year in the United States. The unprecedented increase in the use of radiologic exams on younger women has also raised some additional concerns about how procedures are performed. The...

The site of action of radio-lethal compounds on Micrococcus radiodurans

Creator:: Manes, Jasper Damon, Jr.
Abstract:: Iodoacetic acid and diphenylamine were used in this study to elucidate the mechanisms of resistance of Micrococcus radiodurans to radiation. This organism, a gram positive, non-spore forming, salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in the absence of radio-modifying agents. M. radiodurans, when grown in media containing...

A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

Creator:: Ley, Ronald Douglas
Abstract:: Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

Design techniques for radiation hardened-phase locked loops

Creator:: Nemmani, Anantha Nag
Abstract:: Spacecrafts experience radiation in the course of their operation and all electronic equipment on board these spacecrafts has to be designed to withstand the effects of this radiation. This thesis describes the effects of total ionization dose (TID) and single event transients (SET) in phase-locked loops - an important circuit...

Pressure trunk injections of potassium as a possible short term corrective measure for potassium deficiency in sweet cherry (Prunus avium L.) and prune (Prunus domestica L.)

Creator:: Robbins, Scott Hill
Abstract:: The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄. solutions on the mineral content, growth, yield and fruit quality of sweet cherry and mineral content of prune were investigated. A complimentary study presented in Appendix 1, was conducted to evaluate the short term effectiveness of K soil amendments, mulching...

The irradiation resistance of food pathogens contaminating seafoods

Creator:: Dutiyabodhi, Pisawat
Abstract:: Studies have been made to determine the limits of tolerance to gamma radiation for 15 cultures of the following bacterial species both in culture media and in irradiation-sterilized seafoods (crab-meat, halibut and shrimp) inoculated with Salmonella (seven species), Shigella (three species), and one species each of Neisseria, Myco-bacterium, Esctrerichia, Proteus...

Effects of neutron irradiation on high-purity vanadium

Creator:: Stevens, Richard Francis, Jr.
Abstract:: Because of the potential elevated-temperature applications of high-purity vanadium in nuclear reactors an investigation was conducted to determine the effects of nuclear irradiation upon the properties of the pure metal. The results of this investigation indicated that the effects caused by irradiation, increased strength and hardness and decreased ductility, could...
