A delayed-coincidence spectrometer system was developed to measure nuclear lifetimes in the picosecond region by the centroid-shift method. liming signals were derived from two plastic scintillators. A specially constructed NaI(Tl) detector was used to detect the gamma-rays which were Corrpton-scattered from one of the plastic scintillators. Energy identification was achieved by sumning the signals from the plastic detector and the NaI(Tl) detector to give the full energy photopeaks. In order to test the effectiveness of the system, the mean lives of the first excited states of Ni60 and Ba134 were measured. The 1.0-psec mean life in Ni60 could not be measured with the present system. The gamma-gamma and beta-gamma coincidence experiments gave the mean life of the first excited state of Ba134 as 6.1 ±0.8 psec and 4.8 ±0.6 psec, respectively. It is concluded that the shortest mean life that can reliably be measured by the present system is about 5 psec.Ball State UniversityMuncie, IN 47306

Inelastic muon-nucleon interactions will be studied using the nuclear emulsion technique. The momentum of the primary muon beam is 15.8 GeV/C. Muons and other leptons of high energy make excellent probes to study mucleon structure. Muon beams of small contamination, using accelerators, became available in 1965, but the data is limited.In this experiment, we will scan several nuclear emulsion pellicles for muon-nucleon inelastic scatters and study the angular distribution of the scattered muon at 15.8 GeV/C. The results will be compared with previous data and also with the theoretical form factor predictions at this momentum.Ball State UniversityMuncie, IN 47306

The hyperactivity and antisocial behavior, of ambulatory severely retarded patients of a selected state hospital, precluded formalized rehabilitative therapy for them. The purpose of this study was to investigate the effect of behavior modification, through play therapy and positive reinforcement in increasing positive social interactions of the selected patients.The population for this study consisted of thirty-six patients selected from two wards of institutionalized retardates, with thirty observations made for all subjects. For the experimental subjects, the observation session procedures for sessions one through ten, and twenty-one through thirty were identical with the control group. In sessions eleven through twenty, the therapist interacted with the experimental subjects with the toys and gave verbal praise reinforcement for subjects' positive social behavior.It was concluded from this study that the toys alone produced a degree of increased positive social responses, but the greatest change of all the subjects was found for the experimental subjects, during the period of play therapy and reinforcement. This indicated that there was a degree of behavior modification from play therapy and positive reinforcement.Ball State UniversityMuncie, IN 47306

This study has objectively assessed the role of fear of death and dying in a retrospective biased sample of 83 patients treated for initial breast cancer at Ball Memorial Hospital, Muncie, Indiana, 1972-1973.Increased delay is significantly associated with advanced clinical stage of breast cancer. No significant relationship exists between temporal delay and the Collett-Lester Fear of Death Scales. Small positive correlations exist between delay and the Fear of Death Scales, The strongest fear is the fear of dying of self. Fear of death of self is significantly related to advanced clinical stage of breast cancer. Fear of death of others, fear of dying of self, and fear of dying of others are not significantly related to clinical stage of breast cancer. A significant linear relationship between age and temporal delay is present. Increased delay was not significantly related to other psychosocial variables tested. Tendencies to greater delay occurred with certain psychosocial variables.Advanced clinical stage of breast cancer was significantly related to unhappiness at the time of occurrence and the idea of hereditary tendency. Stage of disease was not significantly related to other psychosocial variables tested. Advanced age and social position tend to be associated with advanced breast cancer. Significant relationships existed. between fear of dying of others and reason for seeking medical treatment, and fear of death of others and worry about things other than health and the ides of a hereditary tendency. No significant relationships existed between the Collet Lester Fear of Death Scales and other psychosocial variables tested. Fear of dying of self remained the strongest fear, Some tendencies to greater delay and fear of death and dying were presentBall State UniversityMuncie, IN 47306

The identification of stopping charged particles in G.5 nuclear emulsion by using a residual range ionization method has been investigated in this experiment using a large stack of ILFord, G.5 nuclear emulsion pellicles exposed to 450 and 435 Me V/c K ˉ mesons at the Berkeley Bevatron.The restricted rate of energy loss vs kinetic energy for protons has been calculated theoretically, and given in Barkas(9). Then for given values of B , we calculated the restricted rate of energy loss vs the kinetic energy of muon, pion, kaon, and sigma particles.The measurement of the residual range and the counting of blobs in each residual range segment were carried out for four known stopping pions tracks. A second degree polynomial computer fit program was used to interpret the plot of residual range vs blobs/100 μ m. Then a particular point on the plot was chosen as a reference for normalizing the relative grain density (g*), theoretically and experimentally. Next, theoretical tables of residual range (R) vs relative grain density (g*theo) were calculated for muons, pions, kaons, protons, and sigmas. Those portions of the latter tables, for which (g*theo) was less than - 2, were used for the above mentioned theoretical plot of residual range (R) vs relative grain density (g* theo). The theoretically predicted curves were then tested by experimentally measuring the residual range and counting the blobs of each range segment of two selected stopping particle (primary) tracks which we suspected to be stopping kaon tracks. Then the second degree polynomial computer fit to the plotted data of the measured residual range vs blobs/l00 μm was carried out for each of the two suspected stopping kaon particles. Three points from each curve were picked and superimposed on the theoretical curves. The results were good but showed that it is necessary to measure a sufficiently long residual range, and more than one segment of blob-counts should be used along the measured residual range for accurate identification of the given particle.Ball State UniversityMuncie, IN 47306

The purpose of this thesis was to determine whether couples gained any knowledge as a result of attending expectant parent classes.A pre-class and post-class questionnaire was utilized to evaluate the learning. Areas covered were pre-labor symptoms, labor and delivery, activities post partum period, the newborn, family relationships, family planning, and relaxation and breathing patterns. Some couples were observed during labor and delivery to evaluate the use of the relaxation and breathing patterns and the husband's participation.This study indicated that husbands and wives did learn as a result of attending the expectant parent classes. It also indicated that the husbands actively participated in the labor and delivery phases and that the relaxation and breathing patterns were utilized to various degrees during labor and delivery.Ball State UniversityMuncie, IN 47306

This thesis investigated whether or not the parents of children seen in emergency treatment department could learn the child's medical regime better if reinstructed on the regime in a quiet place after the child has been discharged from the department. An experimental group reinstructed under the above conditions was compared with a control group.The investigation revealed that there was better learning of medical instructions by those parents reinstructed on the medical regime under the ideal conditions in the emergency treatment department.Ball State UniversityMuncie, IN 47306

Foliar application of the phytotoxic herbicide diquat dibromide was made to twenty tuliptree seedlings actively growing under field conditions on October 6, 1973, at the Purdue Davis farm in Randolph County, Indiana. Herbicidal extraction was accomplished by two extraction procedures: Langlois, et. al., (1963), and a method described in the Pesticide Analytical Manual (9/1/67). Herbicidal application methods utilized two concentrations and three time periods for translocation to occur.Results from the herbicidal application to the tuliptree seedlings indicate that diquat dibromide is present in all parts of the seedling trees within a two hour time period, and that relative amounts of diquat per plant organ are time dependent.Ball State UniversityMuncie, IN 47306

This project was undertaken to study the feasibility of constructing a briefcase size, portable computer system that could store and display the entire file of medical records of a practicing physician. The concept and most of the preliminary designs had been formulated previously. The project paper has given some of the design parameters as well as enough technical data to give the reader a clear idea of the project limits. No attempt was made to allow any reader enough technical information to construct a similar device.The concept of feasibility is herein explored, and the attempt is made to show that such a device is now constructed in sections and each section performs its function properly. Time did not allow the finishing touches to be worked out, but every aspect described in the "proposal" has been demonstrated to be feasible. Photographs in the Appendix depict the various aspects of construction.Ball State UniversityMuncie, IN 47306

This creative project is a series of individualized instructional packets, entitled Science Education Packets designed for use fn a girls' juvenile corrections institution. The materials were modified from a commercial ditto series produced by Ortleb and Cadice (1967). The series deals with science topics such as Earth Science, Physical and Chemical Changes, and Our Living World. The series was originally designed for group classroom situations. As presented here, each series is presented as a self-instruction unit fn which the child elects to work.The author has found the production of units on an elementary level is best when dealing with the transient population of a correctional institution. The child has an opportunity to achieve at maximum capacity in a minimal time.Ball State UniversityMuncie, IN 47306
