A dendroclimatological analysis of white oak (Quercus alba L.) growth rings from Christy Woods, Muncie, Indiana, with local climatic data

Stahl, James Richard 03 June 2011 (has links)
The purpose of this investigation was to evaluate the usefulness of white oak tree-ring sensitivity to local climatic information. White oak core samples were taken from Christy Woods in Muncie, Indiana. Tree-ring measurements were standardized and summarized using computer programs from the Laboratory of Tree-Ring Research, Tucson, Arizona.Low mean sensitivity in each series, and a variance component for the total group chronology of 30.23% indicated that annual growth increments of white oak were less than moderately limited by annual mean growing season precipitation and temperature. It may be inferred that a variety of factors have limited growth diminishing the affects of macroclimatic variations on growth at this site.By use of stepwise multiple regression analysis annual growth increment for the mean chronology was positively correlated to mean growing season precipitation. Annual growth increment was negatively correlated to mean growing season temperature. Only 24% of the total variability in the indices was attributable to the dependence on precipitation and temperature.Ball State UniversityMuncie, IN 47306

Seasonal distribution of the fish pathogen Aeromonas hydrophila and serological evidence of Aeromonas hydrophila infection in fish populations of the White River, Muncie, Indiana

Ellis, Mark 03 June 2011 (has links)
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

Cottontail rabbit utilization of artificial burrows in east-central Indiana

Nelson, Glen A. 03 June 2011 (has links)
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 intersection and interface of computer graphics and computer-assisted instruction

Truex, Jere L. 03 June 2011 (has links)
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

The effects of exercise during pregnancy upon maternal adipocyte characteristics and fetal growth in Wistar rats

Treadway, Judith L. 03 June 2011 (has links)
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

An assessment of nursing knowledge regarding total parenteral nutrition in a hospital setting

Tracey, Marsha L. 03 June 2011 (has links)
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

An archaeological resource management plan for the prehistoric resources of the White River resource system with study area B, Marion and Hamilton counties, Indiana

Beard, Thomas Clark 03 June 2011 (has links)
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

The predictive value of SAT and NLN-PNG scores for success on State Board Test Pool Examination

Nation, Sue 03 June 2011 (has links)
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
