A study of Germanium phthalocyaninesMahabbis, Mohamed T. 03 June 2011 (has links)
This thesis has involved an attempt to form a germanium-carbon bond through the reaction of germanium compounds with dilithium phthalocyanine, metal-free phthalocyanine, methyl magnesium iodide, phenyl magnesium bromide, and 1,3-diiminoisoindoline. The reaction products were examined in several ways to help establish their identity. Chemical and spectroscopic analyses were used to determine the nature of the two trans groups in the phthalocyanine compounds. Infrared spectra implied the formation of the germanium-carbon bond.Ball State UniversityMuncie, IN 47306

Movements of western chorus frogs, Pseudacris triseriata triseriata (Wied), tagged with Cop6sp0sGleason, Michael R. 03 June 2011 (has links)
The movements of Western Chorus Frogs, Pseudacris triseriata triseriata, were studied from May 1, 1975, to May 16, 1975, on the Robert H. and Esther L. Cooper Woodland Area near Muncie, Delaware County, Indiana. The purpose of the study was to obtain detailed information on the day-to-day and hour-to-hour movements and habitat selection of the species immediately following the breeding season.Five Chorus Frogs were tagged with approximately 50 μc Co60 , and were released at a common point near a forest grassland interface. Study frogs were then located at two hour intervals for several 24-hour or 48-hour periods by searching the area of previous contact with a portable survey meter equipped with a scintillation probe.Horizontal movements are apparently random in direction and not influenced by habitat or meteorologic conditions other than moisture. They occur during daylight hours and at night and seem only to be influenced by moisture conditions of the microhabitat.Vertical movements are also influenced by moisture conditions, and occur primarily just before and after dawn.Chorus Frog preference for either a grassland or forest habitat was not determined by this study.Ball State UniversityMuncie, IN 47306

On the approximation of linear integral equationsAli, Agha Iqbal 03 June 2011 (has links)
Integral equations form an important subject with applied mathematics due to their occurence in a variety of models of physical problems. The intent of this thesis is to present in a simple and concise manner the theory of integral equations in the context of their solution. A survey of the types of methods used for the approximation of linear integral equations is made along with the types of equations to which they may be applied. Detailed examples are presented for each of the methods discussed and wherever feasible, computer methods are employed.Ball State UniversityMuncie, IN 47306

A characterization of homomorphisms between groupoids and the relationships existing among themGrant, David Joseph 03 June 2011 (has links)
This thesis presents a partition of the class of homomorphisms between groupoids of n-tuples in a system g = (G,&,@), where G = { a,b,c,d,e }is a set of five elements such that: 1) a is the &-identity and annihilates all elements under @; 2) b is the @-identity; 3) d absorbs all all elements except e under & and all elements except a and e under @; 4) e absorbs all elements under & and all elements except a under @; 5) & is a binary operation on G and is commutative in G; 6) @ is a binary operation on G and is left-distributive over & in G.Matrices over g were examined for characteristics which would determine different atomic properties of homomorphisms. A matrix operation @ was defined, which allowed the homomorphisms of groupoids of the form, (G(n) , &), to be modeled by a matrix equation. Using the atomic proper ties, a partition of the class of homomorphisms between groupoids was developed, and an example of an element in each of its disjoint subsets was presented. A listing of theorems was also derived.Ball State UniversityMuncie, IN 47306

Drumlins : are they stratified glacial features by size and lithology?Follis, Michael 03 June 2011 (has links)
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

A comparative study of the effects of pathogens on the European corn borer, Ostrinia nubilalis, in laboratory and field studiesManuszak, John Louis 03 June 2011 (has links)
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

Effects of tracking error on solar light concentration by a Fresnel lensDaniel, Noel L. 03 June 2011 (has links)
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

Palladium (II) and platinum (II) complexes of cyanomethyl (diphenyl) phosphine and o-cyanophenyl (diphenyl) phosphineTrujillo, Horeb 03 June 2011 (has links)
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

Characterization of edaphic relationship of the Spicebush subcommunityCartwright, Kelly L. 03 June 2011 (has links)
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

Analysis of polyamines and serotonin by mass-analyzed ion kinetic energy spectrometryLloyd, Larry D. 03 June 2011 (has links)
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
