Moon Island, one of 180 drumlins in the Boston, Massachusetts area, is composed of a compact, clayey till with the southeastern slope of the drumlin forming a cliff caused by marine erosion. Samples of pebbles from the cliff-face and drumlin surface show horizontal stratification of till units that are differentiated by pebble size. The stratification is interpreted as evidence that the drumlin was formed in two stages: (1) one or more ice advances or surges which deposited the size-distinctive till layers. Stratigraphic variation of pebble lithologies in the till indicates that the till layers were probably deposited by at least two different ice lobes, and (2) an ice advance which carved the drumlin form without distorting or reshaping the horizontal till layers.Ball State UniversityMuncie, IN 47306

In some areas the effect of pathogenicity of microorganisms upon the European corn borer have been explored. The microorganisms studied were: Nosema, pyraustae, Nosema necatrix, and Bacillus thuringlensis var, thuringiensie. Most studies have been limited to either laboratory or field work. In this thesis, a comparative study of mortality, percent infection, and tune intervals in which infection occurs have been explored, in the field and the laboratory studies.It is concluded: (1) field recovered borers at different day intervals showed interaction between the experimental microorganisms and time intervals (2) that the microorganisms used in the field, especially N. necatrix, may be used as effective microbial control agents against Ostrinia nubilalis.Ball State UniversityMuncie, IN 47306

The major objective of this study was to analytically determine the effects of small transverse solar tracking errors on the concentrated intensity profile generated by a 22-inch wide, f-number one, linear Fresnel model lens. Transverse tracking error is caused by the misalignment of the lens optic axis and the center of the sun in a direction perpendicular to the lens optic axis. The analytical method consisted of extending an earlier theoretical model developed by Cosby3 in which the solar disk was perfectly tracked; thus the tracking error problem is treated as a perturbation of the basic theory. Data was obtained using extensive computer calculations.Results indicated that in the presence of transverse tracking error, lens serrations (upper half serrations) on the same side of the lens optic axis as the sun differ significantly from the lens serrations (lower half serrations) on the opposite side of the lens optic axis in their concentration characteristics. Incident angles of sunlight are greater for upper half serrations causing greater angles of refraction at the second surface. The peak concentration ratio values are observed to shift in the negative intercept direction in a linear relationship with tracking error angle. It was observed that the 90% target width monotonically increased, e.g., by 100% and 700% for transverse tracking errors of 1/2° and 2-1/2°, respectively. It is concluded that the dominant cause for the 90% target width increase is the intensity profile shift itself. Some lesser influence results from increasing intensity profile skewness and profile broadening for IR wavelengths caused by greater IR refraction with increased transverse tracking error.Ball State UniversityMuncie, IN 47306

Cyanomethyl(diphenyl)phosphine (L) and o-cyanopheryl(diphenyl)phosphine (LI) react with H2PdX4 (X = Cl, Br) or K2PtCl4 to yield complexes of the type MX2E2(M = Pd, Pt; E = L, L'). Infrared and nuclear magnetic resonance spectroscopic data indicate that L and Ĺ are coordinated through the phosphorus atom, and that the Land L'-containing complexes have cis and trans geometries, respectively, The MC12E2 complexes react with potassium thiocyanate to yield derivatives of the type 1,(NCS):,L9, in which the thiocyanate groups are nitrogen-bonded to 'the metal.The reaction of L, L' or PdX2E2 (E = L or L') with either PdX2 (X = Cl, Br) or Na2PdX4, in a 1 to 1.1 mole ratio yields complexes of the type (PdX2E.)n. Infrared data indicate that the (PdX2L)n complexes are ligand- and the (PdX2L')n complexes halogen-bridged species.Ball State UniversityMuncie, IN 47306

The plant used in this study was the woodland shrub, Spicebush, Lindera benzoin (L.) Blume. Spicebush, is characteristically found on a poorly drained soil, within Beech-Maple or Mixed Mesophytic forests. It commonly occurs as pure stands in small patches within the shrub layer of mesophytic forests.The objective of this study was to characterize the soil type upon which Spicebush crows and to relate the soil-plant relationship in tears of establishment, growth, and development of the Spicebush. The variables used in accomplishing this objective were based on the physical and chemical regimes of Spicebush subcommunities. Ginn Woods, a climax beech-maple forest in Delaware County, Indiana, was used as a study area. Spicebush subcommunities within the woods were rapped and three representative sites were selected. The factors examined in the study were soil profile, soil moisture and temperature, soil and tissue levels of nitrate, phosphorus and the trace element metals Cr, Cu, Zn, Mn, Fe, Pb, Ni, and Cd. Analysis of the soil horizons was performed by soil core and visual characterization at the representative sites. Soil moisture blocks and temperature probes were buried at 5 centimeter and 20 centimeter depths at the sites for determination of soil temperature and available soil moisture. Data was collected at the sites every other day. Nitrate and phosphorus levels for plant tissue and soil were analyzed by the Kjeldahl Method and Spectrophotcznetric Method, respectively. An Atomic Absorption Spectrophotanetric Unit was used to determine amounts of ppm. of the metallic salts in samples of soil and leaf tissue.Ball State UniversityMuncie, IN 47306

Mass-analyzed ion kinetic energy (MIKE) spectra were obtained for serotonin and the polyamines. The predominant reaction observed was the loss of NH3 from the protonated species. The MIKE methodology was applied to the direct analysis of polyamines in bacteria without any sample preparation.Quantitative analysis was shown to be possible with deuterated putrescine as an internal standard.Ball State UniversityMuncie, IN 47306

The purpose of this study was to evaluate the applied use of a commercial UV unit for air sanitation in the cold storage rooms of a local supermarket chain. On-site testing was performed in four supermarkets (two control stores without UV units and two experimental stores) and one warehouse employing UV units. Meat processing, meat storage, and produce storage rooms were randomly sampled by the open plate and swab methods. Commonly occurring "representative microorganisms" were then selected and identified as Pseudomonas sp., Flavobacterium sp., Bacillus sp., Rhodotorula sp., and Penicillium sp. which were taken into the laboratory for UV testing. Representative microorganisms were effectively killed by UV when tested in the laboratory. Exposure to UV was conducted on agar streaked plates and aerosol suspensions of the microorganisms. The effectiveness of the commercial UV unit in the applied setting was less easily determined due to a complexity of changing variables between rooms and between stores. In general, the UV unit appeared to be of noticeable benefit where airborne yeasts and molds were predominant. This occurred in produce rooms. Regular maintenance of the UV unit was necessary for maximum efficiency. The meat processing room presented unique problems relating to procedural habits of the personnel. In all supermarket cold rooms, good "housecleaning" remained the key to controlling microorganisms.Ball State UniversityMuncie, IN 47306

3-Cyanopropyl(diphenyl)phosphine was synthesized from chloro(diphenyl)phosphine and 4-chlorobutyronitrile. This new ligand, along with (C6H5)2PCH2CN and (C6H5)2PCH2CH(CH3)CN were reacted with Re(CO)5X (X=Cl,Br) in 1:1 and 1:2.5 (metal:ligand) mole ratios.For all ligands, complexes with the stoichiometry Re(CO)3L2X were isolated from the 1:2.5 mole ratio reactions. Spectroscopic data suggest that the CO groups are facial and the ligands cis to each other.For all ligands, complexes with the stoichiometry Re2(CO)6L2X2 were isolated from the 1:1 mole ratio reactions. Spectroscopic evidence suggests that all the complexes are ligand bridged dimers which utilize the phosphorus and nitrogen lone pairs of the ligand.Ball State UniversityMuncie, IN 47306

The ligands o-cyanophenyl(diphenyl)phosphine and bis(dimethylamino)(o-cyanophenyl) phosphine were synthesized from o-bromobenzonitrile and diphenylchlorophosphine and bis(dimethylamino)chlorophosphine, respectively. Both ligands were identified by IR, NMR and physical constant data. The reaction of bis(dimethylamino)(o-cyanophenyl)phosphine with sulfur or CH3I yields complexes of the stoichiometry [(CH3)2N]2(o-C6H4CN)P(X) (X=S, CH3I). NMR and IR spectral data suggest that the phosphorus is the site of reaction.Reaction of 2-cyanocyclohexyl(diphenyl)phosphine, 2-cyanocyclopentyl(diphenyl)phosphine or 2-cyanoethyl(dipheriyl)phosphine with M(CO)6 (M=Mo,W) and NaBH4 in refluxing ethanol yielded complexes of the stoichiometry M(CO4)L (L=2(aminomethyl)cyclohexyl(diphenyl) phosphine, 2(aminomethyl)cyclopentyl(diphenyl)phosphine, or 3-aminopropyl (diphenyl) phosphine). The infrared spectra of the complexes display two v(NH) bands at ca. 3360 cm-1 and 3308 cm-1 which are indicative of coordinated NH2 groups which result from the reduction of the CN groups. Four v(CO) bands are observed for the complexes which indicates that the compounds are of cis-configuration.Ball State UniversityMuncie, IN 47306
