This thesis compared the bird and mammal populations utilizing three multiflora rose hedgerows in Delaware County, Indiana during a one year period.. Results were based on weekly observations and snap-trapping records. Relative abundance and frequency indices were used in comparing populations. Birds were also classified according to their seasonal occurrence on the areas, and activities of birds and mammals were reported.This study showed that the species composition of the areas was similar but that population sizes and degree of species utilization varied as a result of adjacent land use and disturbance rather than the length or volume of the hedgerows.Ball State UniversityMuncie, IN 47306

The objective of the project was to develop a machine language to assembler language translator for the IBM 360 computer.

That is, source modules in any language, object modules and load modules can all be processed by the translator. The output from the translator consists of a machine language display, an assembler code display, a storage map display and a display of register contents at initiation and termination of module processing.Ball State UniversityMuncie, IN 47306

Finite element computer modeling has been compared with scale modeling of vertical block uplifts of continuous, homogeneous, and isotropic material, representing geologic structures. Gelatin was used as the standard modeling material with deformation limited to the elastic range. Computer models with dimensions identical to the gelatin were varied in boundary conditions, material constants, and uplift configuration until close approximation to the gelatin model occurred. Zero density computer cases were obtained to isolate the effects of gravity on the deformation and points of maximum shear and tensile stresses were indicated and co-roared with weighted examples.After achieving close agreement between the two techniques, additional gelatin and computer models, both with elastic properties greater than the standard., were compared and evaluated to substantiate the results. Applications to field situations are indicated and areas for additional comparisons are suggested for further investigations.Ball State UniversityMuncie, IN 47306

Monthly whole-water phytoplankton samples were collected in Lake Michigan near Michigan City, Indiana from June, 1973 to May, 1974 on three transects at eight stations with depths ranging from 5 to 18m.A total of 226 taxa were identified in composite samples. The diatoms Fragilaria crotorensis (16;6), Thalassiosira fluviatilis (11%), and Tabellaria fenestrata (95%), numerically dominated the Lake Michigan phytoplankton assemblage during the study period.Principal components ordination revealed a well defined pattern of seasonal succession. No consistent differences between stations were found. Species diversity indices generally indicated a high level of community organization in spring and fall months and lowered estimates for summer and winter months.The phytoplankton community was dominated by diatoms throughout the year. Green and blue-green forms showed greatest abundance in the summer and. early fall with only minor occurrences during the remainder of the sample period.Species encountered in this study indicate continued succession of Lake Michigan phytoplankton and eutrophication of the southern near-shore water.Ball State UniversityMuncie, IN 47306

Biopotential amplifiers and DC amplifiers in general play an important role in neurophysiological research and modern medical practice. This thesis investigates the application of recent semi-conductor technology to the design of a high-performance amplifier for EEG, EKG, and EMG. This amplifier can also be used with low-level transducers. In particular, the performance of a BJT OP AMP version is compared with that of an amplifier utilizing FET OP AMPS.Ball State UniversityMuncie, IN 47306

Various samples of ultra-pure germanium were lithium diffused for approximately one day at temperatures ranging from 300° to 4500 C under an inert atmosphere. Lithium precipitation kinetics were characterized utilizing D-C electrical conductivity measurements at room temperature. Selected samples were subsequently exposed to an estimated total integratedfast-neutron flux of order 1012 /cm2. Following the irradiation process, lithium precipitation subsequent to annealing at various temperatures was studied, again through the eletrical conductivity. It was noted that the presence of the fast-neutron generated disordered regions can initiate precipitation in lithium -diffused germanium in which no post-diffusion precipitation was observed.Utilizing Frank S. Ham's Theory of Diffusion -Limited Precipitation for spherical precipitate centers, and the precipitation kinetics data obtained, the density of precipitate centers was calculated as a function of annealing temperature. The variations in the density of precipitate centers with annealing temperature suggest this method as possibly useful in studies of annealing behavior of disordered regions in germanium.Ball State UniversityMuncie, IN 47306

Food habit analyses of the young-of-the-year alewife in lake Michigan show zooplankton was the primary component of the diet in 1972 and 1973. Cyclops bicuspidatus contributed the largest portion of the diet in both years. The dominant cladocerans consumed in each year were Bosmina longirostris, Daphnia retrocurva, Chydorus sphaericus, Polyphemus pediculus, and Diaphanosoma brachyurum. Diaptomus spp. was the only other copepod of importance. Chironomid larvae and pupae provided minor volumes in both years.Monthly food habits revealed a general decline in cladoceran percent volume from August to October at the Michigan City and Dunes transects. Bosmina longircstris was the predominant cladoceran in August of both years at both stations. Chydorus sphaericus was a major food item in September, 1972 at the Michigan City transect, and August and September, 1972 at the Dunes transect. Daphnia retraocurva was a primary prey species in August of each year and in September, 1973 at Michigan City, and in August and September of both years at the Dunes transect.Polyphemus pediculus percent volume was greatest in August and September, 1973 at both stations. At the Michigan City transect, Cyclops bicuspidatus was the dominant food item, and was more important in September than August in both years. In contrast, C. bicuspidatus contributed a major portion of the alewife diet at the Dunes transect in each year, but was more important in August than September. Diaptomus spp. percent volume was greatest at the Michigan City transect in October of both years. Chironomids were major food items only in August, 1972 at the Dunes transect.Young-of-the-year alewife food habits in relation to fish length indicated that smaller YOY alewives selected smaller cladocerans and copepods, whereas larger alewives preferred larger cladocerans, copepods, and chironomids.Ball State UniversityMuncie, IN 47306

Monthly water temperature profile series were taken in a near-shore harbor area of Lake Michigan near a fossil-fueled electric generating facility at Michigan City, Indiana. Profiles were recorded every 6 hours over 24 hours at monthly intervals from June through September, 1970. Zooplankton and macrobenthos were sampled monthly from stations at 2, 3 and 5 m depths in the heated-water discharge area in the harbor.A thermal plume was present during each sampling series. The extent of the plume varied and was capable of charging directions within short periods of time. Maximum recorded temperature in the plume was 28 C, but the maximum difference in temperature between plume and control area was only 4 C.Zooplankton species diversity was similar between experimental and control areas. Higher zooplankton densities were found in the harbor area but did not appear to be plume related. Benthos populations were lower in the experimental area compared to the control area. Any effect of the heated water in the harbor area was complicated due to the probable but unknown influence of water quality from Trail Creek.Ball State UniversityMuncie, IN 47306

Food habits were examined for the spottail shiner, Notropis hudsonius, in Indiana waters of Lake Michigan from June to October, 1973. Insects were the primary volumetric component of the diet. Chironomus spp. larvae and chironomidae pupae were the most important insect food items consumed. The most important zooplankton organism consumed was the benthic cladoceran Eurycercus lamellatus. Alewife, Alosa pseudoharenqus, eggs were the only other significant food consumed.A monthly comparison of food items taken by spottails showed that Chironomus spp. larvae was an important food item in all months and the primary item in September and October. Chironomidae pupae were important from June through September with greatest percent volume consumed in July, The cladoceran, Eurycercus lamellatus was an important food from July through September, reaching its highest percent volume of the diet in August. Alewife eggs were the major food of spottails in June but were also important in July.Young-of-the-year spottails fed primarily on zooplankton for the first month of their existence, but their diet changed in succeeding months and was similar to that of the adults.Analysis of competition between spottail shiners, yellow perch and alewives revealed important overlap in food items in June, August, September and October. Competition in June was between spottail shiners and yellow perch (100-250 mm) for alewife eggs. In August, the spottail shiner and alewife (140-220 mm) competed for chironomids and the spottail shiner and yellow perch competed for Eurycercus lamellatus. September competition was between spottail shiner and yellow perch (26-100 mm) for chironomids and between yellow perch (26-100 mm) and alewives (140-220 mm) for alewife larvae. Finally, in October, major competition was between yellow perch (100-250 mm) and alewives (140- 220 mm) for alewife larvae.Ball State UniversityMuncie, IN 47306
