Water samples were collected at four sites on the White River, Muncie, Indiana, on a biweekly basis from April 1980 to April 1981, to determine seasonal variation in A. hydrophila density. In conjunction with water sampling, temperature, dissolved oxygen, conductivity and pH were determined at each site. During this period a yearly mean of 589 colony forming units (CFU) per ml was obtained with a range of 0-6350. Peaks in mean A. hydrophila numbers occurred during the summer (1808 CFU ml-1) and early spring (3946 CFU ml-1) with lows occurring in winter (42 CFU ml-1). No significant correlations could be found between CFU values and the physico-chemical parameters studied over the calendar year. However, the compiling of data from May 1979 to April 1981 did yield a significant correlation between A. hydrophila density values and the following water quality parameters: temperature, conductivity, and dissolved oxygen.Fish were collected during June through October 1980 at various sites along the White River, Delaware County, Indiana, for the determination of past or present exposure to A. hydrophila infection by serological and direct isolation methods. Of 102 different fish sera tested, 36% (37/102) had a detectable titer to A. hydrophila (isolate #113). However, the direct isolation method only yielded seventeen percent (8/47) of the fishes sampled to be positive forA. hydrophila systemically. Agglutinins to A. hydrophila were demonstrated in eleven different fish species, whereas five different species revealed no detectable antibody to the specific particulate antigen employed. Estimated CFU ml-1 of A. hydrophila was the only parameter which correlated with the presence of agglutinating antibody to this organism in river fish populations.Ball State UniversityMuncie, IN 47306

This creative project is a FORTRAN language computer program, DIET.FOR, two auxilary programs, CODR.FOR and FOODR.FOR, and accompanying documentation. DIET.FOR is a dietary analysis program in which the user enters the foods which a subject has eaten. The program then calculates the results. The auxilary programs create the data files on which the nutritional analysis is based. The documentation is designed as a tutorial to aid the user.Ball State UniversityMuncie, IN 47306

Cottontail rabbit, Sylvilagus floridanus, utilization of 16 artificial burrows was studied during the winters of 1976-1977 and 1977-1978. The burrows were located in Delaware County, Indiana, in four vegetative cover types including ungrazed deciduous forest, fescue grassland, wildlife plantings, and multiflora rose hedgerow. Each burrow consisted of a lay-up chamber made from the upper portion of a 55-gallon steel drum set on top of the ground. Two entrances made of slotted plastic drainage pipe extended in opposite directions. Soil was filled around the burrows and over the entrance tunnels. Cottontails found in the burrows were captured, marked by ear tagging, sexed, weighed, measured and released.Burrow utilization was noted in each cover type with greatest usage occurring in the multiflora rose hedgerow and in the forest. Snow cover and low ambient air temperature seemed to be the two most important factors contributing to burrow usage.Ball State UniversityMuncie, IN 47306

The trap of "reinventing the wheel" could cause us to neglect the tools already developed. Instead of a negative or dreaded aspect, the possibility of turning this potential liability into asset should be investigated. Increasingly, computer-assisted instruction and computer-managed instruction seem to be gravitating toward the inclusion of computer graphics. The ultimate extrapolation of this tendency would seem to be the symbiotic relationship generated and controlled through the interaction of the person and the machine. The burgeoning world of video applications could probably be viewed as the fine edge for teaching and learning via a computer. As a result of this conclusion, this thesis provides research into the possible and actual synergism generated by CAI and computer graphics.Ball State UniversityMuncie, IN 47306

This study examined the effects of maintaining exercise training throughout pregnancy upon metabolic and physical properties of parametrial fat cells and fetal growth in Wistar rats. Eight weeks prior to mating the animals (n=10) were trained to run for 2 hrs/day, 5 days/wk at 31 m/min up an 8 0 incline. Control animals (n=6) remained sedentary. All animals were mated and trained animals resumed running on the second day of gestation. There was no variation in body weight (p > 0.05) between the trained (T) and sedentary control (S) rats at mating but S weight was significantly greater (p < 0.05) at Day 19. The T mothers had significantly smaller fat cells (p < 0.05) than S but cell number did not differ (p > 0.05). The rate of glucose oxidation (1C-1) by cells from T animals was significantly higher (p < 0.05) than the S in the presence of insulin, but much lower than oxidation rates of non-pregnant trained animals. In terms of the fetus, training reduced litter size (p < 0.05) and increased the incidence of fetal resorption. The results of this study indicate that the training adaptation of the adipocytes is largely lost during pregnancy but insulin responsiveness is maintained at a higher level than sedentary controls. This coupled with the apparent adverse effects of the training on the fetus suggests that exercise during pregnancy should be more closely investigated.Ball State UniversityMuncie, IN 47306

The problem addressed in this study was the assessment of the knowledge of newly graduated registered Purse candidates about Total Parenteral Nutrition and the effects of practice on knowledge. The study used a quasi-experimental approach to determine the amount of knowledge the subjects possess about Total Parenteral Nutrition at the time of employment and after a period of six months working with patients receiving this therapy.An investiagtor made multiple choice test consisting of thiry items was used to assess the knowledge of the subjects. A score of 75% on the test instrument was considered to indicate adequate knowledge of Total Parenteral Nutrition therapy.The sample was a convenience sample consisting of 33 newly graduated registered nurse candidates. Associate, diploma and baccalaureate graduates were represented in the study.All subjects in the study scored less than 67% on either test during the study. The results of this study may have been influenced by the small number of exposures to patients receiving Total Parenteral Nutrition therapy.Ball State UniversityMuncie, IN 47306

This is a study of the known archaeological resources of the Upper East Fork of the White River in Marion and Hamilton Counties, Indiana, and a proposed management plan for the prehistoric cultural resources as a part of the White River Resource System. The extensive population growth and resultant impact of urbanization to the natural and cultural resources within Central Indiana along the White River from Martinsville to Muncie has exemplified a need for proper management and conservation of the remaining resource base. This study is an effort to illustrate the need for proper management of the archaeological resources within the whole corridor of the White River Resource System, provide a preliminary plan and strategy for the identification and evaluation of the resources and identify known critical management needs within Marion and Hamilton Counties.Ball State UniversityMuncie, IN 47306

In order to introduce the investigation contemplated in this thesis, let us consider the differential equation d3y d2y dyz3 ____+ z2___(b0 + blzm) + z - (c0 + clzm) dz3 dz2 dz+ (d0 + dlzm + d2z2m) y = 0Here, m is an arbitrary positive integer and the variable z is complex as are the constantsbi,ci (i=0,1) and di (i=0,1,2) with d2≠0. It is also assumed that the difference of no two roots of the indicial equation about z = 0 is congruent to zero modulo m.Ball State UniversityMuncie, IN 47306

The problem examined in this study was the relationship between the SAT and NLN-PNG scores and success rate on SBTPE. This predictive study utilized an ex post facto approach. This investigator obtained administrative permission to utilize the data from the files at this diploma school of nursing. The convenience method of nonprobability sampling included the scores of graduates in the years 1977 through 1981. Pearson correlation coefficients were computed for the predictor variables with each of the five SBTPE and the mean, indicating a moderate positive linear relationship. Correlation coefficients and simple regression analysis indicated that the SAT combined score and NLN-PNG combined score was somewhat of a predictive measure of SBTPE success at the time of admission to the program, while the multiple regression analysis indicated that a better combination of predictor variables for SBTPE success was the SAT combined score and the NLN-PNG composite score.Ball State UniversityMuncie, IN 47306

In this study, I rewrite a relational database, originally written in Pascal, using the Ada language. I tried to exploit certain features of Ada that make it a powerful language, such as packages, in an attempt to have as general a program as possible. So the purpose here was to see how, by using the Ada language, a relational database program could be inproved by eliminating certain restrictions of the Pascal language.Ball State UniversityMuncie, IN 57406
