This thesis includes a summary of some of the early developments of M.IR and NQR detection. Elementary introduction to NQR detection is also discussed. Finally the construction of a high level NQR Spectrometer operating in the regenerative mode is treated. This regenerative spectrometer, originally designed by D. Sill, M. Hayek, Y. Alon, and A. Simievic and published in Rev. Sci. Instr. 38, 11 (1967), is discussed extensively.Ball State UniversityMuncie, IN 47306

Daily and seasonal movements of adult alewives, Alosa pseudoharengus, were studied at depths of 5 to 18 m in Indiana waters of Lake Michigan near Michigan City. Collections were made June to October, 1971, with gill nets and a bottom trawl and June to September, 1972, with gill nets.There was no significant difference (P > 0.05) between trawl and gill net catch rates in 1971 regardless of time of day. Significantly more fish were caught during early summer than late summer. Noon gill net catches did not differ significantly between stations. At 10 m, midnight gill net catches were larger than noon catches and bottom gill net catches were greater than surface catches.In 1972, June and July gill net catches were greater than August and September catches. Spawning was essentially completed by August, and inshore populations of spawning adults returned to deeper offshore areas.Midnight catches were greater than noon catches at all depths. During the day, alewives were farther offshore than the 15 m station, but at night they moved inshore. Crowding of alewives inshore at night resulted in significantly larger catches at the 5 m than at the 15 m station.Food habit studies in 1971 and 1972 revealed zooplankton comprised the major portion of the alewife diet. The copepod Cyclops bicuspidatus was the main zooplankter consumed. Bosmina longirostris and Eurycercus lamellatus were major cladoceran food items. Major non-zooplankton food items were Cryptochironomous, Chironomous, and larval alewives.Zooplankton and cladoceran percent volume in stomachs increased to maxima in July of each year followed by a general decline. Copepods were the dominant food in June. Chironomid larvae were a major component of the diet in May, 1972, and August of both years. The largest percent volume of alewife larvae in stomachs occurred in September.A comparison of daily movements and food habits by percent composition of food items in alewives collected July, 1971, revealed the dominant zooplankton species in alewife stomachs were Bosmina longirostris, Chydorus sphaericus, Alona affinis, Eurycercus lamellatus, Polyphemus pediculus, Cyclops,bicuspidatus, and Limnocalanus macrurus. B. longirostris and P. pediculus, which accumulate at the surface at night, were consumed by alewives in greatest quantity at midnight and sunset when the alewife is near the surface. The benthic species C. sphaericus, A. affinis, and E. lamellatus were consumed in greatest quantity at sunrise when the alewife is near the bottom.Ball State UniversityMuncie, IN 47306

Lake trout (Salvelinus namaycush), chinook salmon (Oncorhynchus tschawytscha), coho salmon (Oncorhynchus kisutch), steelhead trout (Salmo gairdneri), and brown trout (Salmo trutta were collected from April 30 to November 18, 1970 with gill nets at selected sites in Lake Michigan near Gary, Burns Ditch, and Michigan City, Indiana. Catch-per-uniteffort was law and most catches occurred when nets were set in water temperatures in the 50 F (10.0 C) range or lower. Sea lamprey (Petrcnyzon marinas) scars and wounds were found on 25.4% of 71 lake trout captured and fresh wounds occurred on 6.0% of the fish. Scars and wounds were restricted to lake trout 20.0 in. (50.6 cm) or greater in total length and 32.7% of the 55 fish in this size group carried scars or wounds.Food items in stomachs of 39 lake trout, 34 coho salmon, and 29 chinook salmon were expressed as percent frequency of occurrence, numerical percent, and volumetric percent. The alewife (Alosa pseudoharenp_us) was the predominate food consumed by all three species. The crustaceans, Mysis sp. and Pontoporeia affinis, were consumed only by lake trout less than 19.0 in. (48.1 cm) total length.The age and growth of 69 known age fin clipped lake trout were examined. The body-scale relationship was TL = 6.2001 + 0.1238 Sc. The mean calculated total lengths for the first 5 years of growth were 5.3, 10.7, 16.3, 21.0, and 24.0 in. (13.5, 27.2, 41.4, 53.2, and 60.8 cm). Annual growth is considerably greater than recorded for Lake Michigan lake trout prior to alewife introduction and dominance. The length-weight relationship was log W = -2.5087 + 3.2338 log L which agrees closely with previous length-weight analyses of Lake Michigan lake trout.Ball State UniversityMuncie, IN 47306

The kinetic study of thermal decomposition of compounds (A)-(E) had been examined. The thermal decomposition product of 1,1-dimethyl-5-(1-isobutenyl)-1-pyrazoline is 1,1-dimethyl5-(1-isobutenyl)cyclopropane, no hydrogen transfer or rearrangement was occured. The only isolated thermal decomposition product of 3-methyl-3,4-dicarboxylic anhydride-l-pyrazoline was dirnethylmaleic anhydride. Since carbon dioxide was found in the decomposition process and the amount of nitrogen gas and carbon dioxide was not the same, it indicated that the decarboxylation product was not come from the nitrogen freed anhydride product.Ball State UniversityMuncie, IN 47306

The outfalls of the eight tributaries entering Grand Lake-St. Marys were monitored during the eleven month period from August, 1972 through June, 1973. Both biological and physical parameters were measured at all sites.The biological parameters that were measured included; fecal coliforms, fecal streptococci, Salmonella spp., Shigella spp., Proteus spp., seudomonas,aeruginosa and Staphylococcus aureus. The physical parameters were; pH, turbidity, water temperature, dissolved oxygen and local rainfall.All eight outfalls were shown to exceed the limits recommended by the U.S. Public Health Service for fecal coliform counts. The ratio of fecal coliforms to fecal streptococci suggested that the pollution came from both human and animal wastes that were carried into the lake in stormwater runoff. The low fecal counts obtained away from the tributaries, in the center of the lake, indicated that the lake was able to recover from the pollution entering at the outfalls. Primary contact recreation in the vicinity of the tributary outfalls is not recommended but the remainder of the lake presents no apparent health hazard.Ball State UniversityMuncie, IN 47306

Using the acetocarmine squash technique to examine pollen mother cells, the meiotic chromosome behavior of each of 16 Rhoeo spathacea plants housed in the Ball State University greenhouse was analyzed with respect to the frequencies of several types of atnormalities and documented with suitable photomicrographs. Among the aberrant types of chromosome behavior resulting from multiple translocations among the 12 chromosomes of each plant were the followings ring and chain formation of chromosomes at diakinesis and metaphase I, adjacent versus alternate chromosome alignment patterns at metaphse I and anaphase I, various abnormal anaphase I and telophase I disjunction patterns, and the presence of excluded chromosomes and micronuclei at telophase I. As a further consequence of the multiple translocations and abnormal chromosome disjunction, many of the pollen grains formed by meiosis were found to be defective and non-viable.Ball State UniversityMuncie, IN 47306

In this research a unique linear pulse amplifier was developed that significantly reduces the spread in pulse amplitudes of those pulses selected from a Ge(Li) detector by a single channel analyzer. This circuit utilizes an operational amplifier with its closed-loop gain automatically controlled by a P-channel junction field.-effect transistor. The amplification is adjusted for each pulse such that the output pulses are constant in amplitude. The performance of the system was analyzed with a multichannel analyzer and it was shown that an improvement in pulse amplitude variation of as much as 29.1 percent was achieved.Ball State UniversityMuncie, IN 47306

Study and experiment indicate that, with existing technology, a modified open Brayton cycle can be used to burn common municipal refuse at atmospheric pressure and produce useful power while scrubbing the combustion product gases to remove pollutants.The hot combustion gases pass from a combustor through a turbine to a region below atmospheric pressure where they are scrubbed and cooled by mixing with water spray. The water spray and gas mixture is then exhausted to atmospheric pressure through a compressor.Although current compressor designs are workable in this application, a new design is needed which will have reduced water drag power loss.Ball State UniversityMuncie, IN 47306

Nictitans glands obtained from mongrel dogs were studied grossly and by regular histological and electron microscopic methods. Special stains including Periodic Acid-Schiff and Sudan Black B were used for the identification of specific macromolecular components.The nictitans gland is a compound tubulo--alveolar gland of apocrine type, although holocrine type of secretory activity is exhibitedby a portion of the gland. Two kinds of secretory materials were secreted by two different types of acinar cells in this gland.The main function of this gland is to secrete lubricant and to keep the eyes in a healthy state. It is thus considered as a supplementary structure to the lacrimal gland.Ball State UniversityMuncie, IN 47306

This study was conducted to assess the incidence of infectious drug resistance among animal strains of Escherlchia coli. Fecal samples were examined from a cattle feedlot southeast of Muncie, Indiana. The use of tetracycline and sulfonamide compounds as feed additives was a common practice on this farm, and theoretically could provide the antibiotic pressure necessary to select for resistant strains. A total of 32 feedlot E. coli were isolated from the feedlot floor. In addition, 10 strains of E. coli isolated from patients with urinary tract infections were introduced into this investigation for comparative purposes. All isolates were tested for antibiotic susceptibility using disc-diffusion methods. Multiple resistant strains were designated as donor organisms and were used in conjugation experiments with an antibiotic sensitive recipient E. coli; wild type K-12 F-.Multiple drug resistance occurred among 21.8 percent of the feedlot E. coli isolated, with a predominance of resistance to chlorotetracycline, tetracycline, and sulfathiazole. Three out of seven multiple resistant donors isolated were able to transfer their antibiotic resistance markers to the recipient K-12 strain. Transferable drug resistance among the clinical isolates occurred in 6 of the 10 donor resistant strains, with tetracycline and ampicillin being the most frequently encountered resistance.Ball State UniversityMuncie, IN 47306
