AbstractThe number and distances of metal-oxygen and metal-metal interactions were determined for various concentrations of aqueous metal nitrate solutions by modified x-ray diffraction techniques. The number of M-O interactions ranges from four to five in the 0.8 M and 1.2 M AgNO3 solutions and from six to nine in the 0.8 M, 1.2 M, and 1.6 M Pb(N03)2 solutions. The 1.6 M Ce(N03)3 solution has eight to nine Ce-O interactions, while one Hg-Hg interaction is found for the H92 (N03)2 solutions. For the silver and lead nitrate solutions, the number of M-0 interactions decreases with an increase in concentration. The cations also effect the number of interactions. Based on the nature of their RDF's, the lead and cerium ions are classified as positively hydrated and the silver ion is negatively hydrated.Ball State UniversityMuncie, IN 47306

AbstractA study of 187 bobwhite, taken from the Salamonie Reservoir and surrounding farmlands in Northern Indiana during November through May, revealed the presence of three species of nematodes:Dispharynx spiralis, Heterakis gallinae, and Subulura,sp. The bobwhite collected showed 37 per cent infestation. The highest rate of incidence was with the Dispharynx spiralis, while Heterakis gallinae was the second most abundant species with 7 per cent infestation. The Subulura species is not identical to any Subulura species reported from bobwhite. Therefore, it is believed that this is the first report of this species from bobwhite.Results regarding food, age, and location revealed little correlation to parasitism in this study.Ball State UniversityMuncie, IN 47306

14.8-MeV neutrons from a Cockcroft-Walton type accelerator/neutron generator have been used to irradiate particulate and ionic samples prepared from river water. Five-minute irradiations were performed in a flux of order 109 neutrons/cm2/sec at target position. Gamma-ray spectra resulting from the activated products were recorded with a spectrometer system consisting of a high resolution Ge(Li) detector (2.5% efficiency at 1330 keV) and multichannel analyzer. Trace elements present in the samples were identified by the characteristic gamma-ray energies and half lives associated with the decay products. Standards of known concentration were used to make relative determinations of the quantities of trace elements present in the water. Elements observed in samples with parts per million concentrations include Al, Ba, Ca, Cl, Cr, Fe, K, Mg, Na, Si, and Sr. Sensitivities for elements not observed in the water samples were also determined for As, Cd, Hg, Ni, Ti, Zn, and Zr.Ball State UniversityMuncie, IN 47306

The present work has endeavored to survey the occurence of adenosine deaminase as well as its multiple forms in normal and some cancerous human tissues. A recent report by Akedo, Nishihara, Shinkai and Komatsu concerning the appearance of the C form adenosine deaminase in cancerous tissues is investigated. The thesis reports, however, the occurence of both A and C forms of adenosine deaminase in almost all normal and cancerous tissues investigated. An increase in C form adenosine deaminase does seem to occur in cancerous tissues, and a ratio method is developed to monitor such an increase in the C form enzyme.Fundamental catalytic and physical parameters are used to characterize the A and C forms of adenosine deaminase in several normal human tissues. Little difference is noted between the two forms of the enzyme. Only substrate specificity for cordycepin is of significant value in differentiating between the A and C forms of the enzyme.Ball State UniversityMuncie, IN 47306

Ctenoconularia deiphiensis,is a new species of the Conulata based on a population of specimens from a phosphatic nodular sandstone at the base of the New Albany Shale (Upper Devonian) at Delphi,Indiana.The transverse ridges possess interridge furrows with bead-like nodes that are not structurally continuous with the ridges. The ridges are altered into four elongate pustules upon crossing the interfacial groove.Ball State UniversityMuncie, IN 47306

Cold worked magnesium powder was investigated to determine the effect of annealing on the residual strains and heat of combustion. The residual rms strains, domain size, and fault probabilities were determined by Fourier analysis of X-ray diffraction data. The heat of combustion was determined by using an adiabatic calorimeter. The results of this study revealed a definite reduction in residual rms strain (0. 0008 to 0. 0003), fault probability (0.0014 to 0. 0001%), and heat of combustion (5662 to 5445 cal/gm) with annealing. The domain size showed an increase from 1400 to 7000 A.Ball State UniversityMuncie, IN 47306

This thesis considered the connections between parabolic partial differential equations of the diffusion type and Gaussian-Markov stochastic processes, in particular the Wiener process. A method has been developed by which certain Wiener integrals of the type∫C0[0,1] exp{t/a ∫1/0 e[t(1-s), 2 √(t/a) x(s) =ξ] ds} o [2√(t/a) x(1) – ξ] dwxHave been obtained as solutions of non-homogeneous heat equations. In the appendix the method has been extended to the evaluation of Wiener integrals of the type,∫C0 [0,t] exp {∫t/0 e [t-s, x(s) + ξ] ds} o [x(s) + ξ] dwx.In addition an inequality which gives bounds for Wiener integrals of the type∫C0 [s,t] exp {-∫t/s F[x( r )] dr} dwx has been deduced.Further, certain parabolic partial differential equations have been solved by building suitable Green’s functions through Gaussian-Markov stochastic processes. Two stochastic processes which exhibit certain interesting features have been obtained and briefly discussed.Ball State UniversityMuncie, IN 47306

A multi-detector spectrometer was constructed to measure garmia-gamma angular correlations in 154Gd from the decay of 154Eu. Gamma-ray multipole mixing ratios were extracted from the data. A modified fast-slow coincidence electronics arrangement with selective routing of data was used. One Ge(Li) detector and three NaI detectors were used in the system for rapid data acquisition. "Real-plus-random" and "random" coincidences were accumulated simultaneously with detectors set at selected angles. Mixing ratios for the first transition in the cascades of 1274-123--keV (2--2+-0+), 1005-123-keV (3+-2+-0+), and 723-996-keV (2--2+-O+) were measured as '5(1274) = 0.02 0.02, '5(1005) = -28+10' '5(723) = 0.02 0.02.'The measured correlation for the 592-1005 keV cascade (2--3+-2+) was analyzed by searching a 157 by 157 array of values for '5(592) and 8(1005); agreement was tested using a Q2 criterion. The best agreement for the mixing ratio of the 592-keV transition was 8(592) = 0.08 0:22; for the 1005-keV transition 8(1005) = -9.5+7. The value 8(1005) _ -9.5+7 is taken to be the better value as a result of experimental considerations. The value for the 592-keV transition had not been previously measured.Ball State UniversityMuncie, IN 47306

This thesis investigated the health needs of economically disadvantaged mothers and children living in Grant County to determine if they were being met by the existing community health resources. The thesis had three main purposes: (1) to identify the health needs of economically disadvantaged mothers and children living in Grant County; (2) to assess the resources in Grant County which provide health instruction and, health services to mothers and children; and (3) to analyze the present health needs as they relate to resources available to economically disadvantaged mothers and children.Inquiry as to health needs of the mothers and children in the group was focused and limited to health care and instruction for expectant mothers during pregnancy, birth, and postpartum. tkbr the children, the need for regular health appraisals for early detection of defects was considered. The limitations of inquiry were designed. specifically to determine the need for initiating and implementing well child clinics, prenatal and postpartum clinics, and family planning clinics in Grant County for the economically disadvantaged mothers and children.Ball State UniversityMuncie, IN 47306

Water samples in the vicinity of Muncie were analyzed for trace elements such as cadmium, chromium, lead, titanium, iron, zinc, barium, calcium, potassium, manganese, sodium, strontium and magnesium. The analysis was made by a lower rotating graphite electrode partly submerged in the water being analyzed. The light emitted by the spark was analyzed using a Littrow Spectrograph. Water samples were taken from five stations along the White River in the Muncie area. The intensities of the spectral lines of trace elements and of standardized solutions were compared for quantitative analysis. Trace metals detected and concentrations in (ppm) found were as follows: Ba 0.04, Ca 72.6,. K 0.05, Mg 23.7, Mn 0.05, Na 27.1, Sr 0.70, Cr 0.02. The elements Ca, Mg, Na and K were expected to be found in high concentration and Ba, Sr, Mn and Cr were expected to be found in low concentration.In a previous study conducted at Ball State, neutron activation analysis was used in this area with positive results for eleven elements. The purpose of the present study was to extend this research by attempting to detect elements by spark-emission spectroscopy concentrating on elements that were difficult to detect by neutron activation analysis.Ball State UniversityMuncie, IN 47306
