An Ab Initio Study Of Specific Solvent Effects On The Electronic Coupling Element In Electron Transfer Reactions, Thomas M. Henderson '98, Robert J. Cave

All HMC Faculty Publications and Research

Specific solvent effects on the electronic coupling element for electron transfer are examined using two model donor–acceptor systems (Zn2+ and Li2+) and several model “solvent” species (He, Ne, H2O, and NH3). The effects are evaluated relative to the given donor–acceptor pair without solvent present. The electronic coupling element (Hab) is found to depend strongly on the identity of the intervening solvent, with He atoms decreasing Hab, whereas H2O and NH3 significantly increase Hab. The distance dependence (essentially exponential decay) is weakly affected by a single intervening solvent atom–molecule. However, when the donor–acceptor distance increases in concert with addition of successively …

A Search For Lithium-Rich Giants Among Stars With Infrared Excesses, Francis C. Fekel, Lyndon C. Watson

Information Systems and Engineering Management Research Publications

The unusual nature of the single, rapidly rotating, lithium-rich K giant HDE 233517, which is currently undergoing significant mass loss, prompted a search for giants with similar properties. High-dispersion spectroscopic observations were obtained of HD 219025, a known lithium-rich infrared-excess giant, plus 39 stars from a list of G and K giants with excess far-infrared emission. The projected rotational velocities of the vast majority of infrared-excess giants appear to be similar to those of normal G and K giants. Six giants have lithium abundances at or above theoretical upper envelope values. The percentage of such stars in the sample of …

Determination Of Chloride Concentration Using Capillary Zone Electrophoresis: An Instrumental Analysis Chemistry Laboratory Experiment, Michael A. Janusa

Faculty Publications

Capillary zone electrophoresis (CZE) has received a great deal of attention as a tool for the separation and detection of low-molecular-mass inorganic ions. CZE is a fast growing analytical technique that uses a low-volume sample accompanied by a high detection efficiency. Since this is a fairly new analytical technique that shows tremendous promise, it should be introduced to students at the undergraduate level. We have developed a CZE experiment that is well suited for an instrumental analysis chemistry laboratory and can be modified for other species or substances.

Rostral-Caudal Variation In Troponin T And Parvalbumin Correlates With Differences In Relaxation Rates Of Cod Axial Muscle, Tierney M. Thys, Jason M. Blank, Fred H. Schachat

Biological Sciences

Relaxation rate is an important determinant of axial muscle power production during the oscillatory contractions of undulatory locomotion. Recently, significant differences have been reported in the relaxation rates of rostral versus caudal white muscle fibers of the Atlantic cod Gadus morhua L. The present study investigates the biochemical correlates of this rostral-caudal physiological variation. Using denaturing gel electrophoresis, a series of fresh muscle samples from the dorsal epaxial muscle region was analyzed and several differences were detected. First, a gradual shift occurs in the expression of two troponin T isoforms along the length of the body. Second, rostral muscles were …

A Slip-Line Field For Ploughing During Orthogonal Cutting, Daniel J. Waldorf, Richard E. Devor, Shiv. G. Kapoor

Industrial and Manufacturing Engineering

Under normal machining conditions, the cutting forces are primarily due to the bulk shearing of the workpiece material in a narrow zone called the shear zone. However, under finishing conditions, when the uncut chip thickness is of the order of the cutting edge radius, a ploughing component of the forces becomes significant as compared to the shear forces. Predicting forces under these conditions requires an estimate of ploughing. A slip-line field is developed to model the ploughing components of the cutting force. The field is based on other slip-line fields developed for a rigid wedge sliding on a half-space and …

Returns To Public Investments In Agriculture With Imperfect Downstream Competition, Stephen F. Hamilton, David L. Sunding

Economics

A multiple-market framework is developed to measure the size and distribution of research benefits. The model considers an upstream raw product market and a downstream finished product market and allows for imperfect competition in the intermediary food-processing sector. A central conceptual result is derived: an increase in raw product output is a sufficient condition for cost- reducing innovations in the farm sector to increase social welfare. A special case of linear farm supply and isoelastic processing production functions reveals that necessary conditions for welfare to decrease are a convergent farm supply shift, an oligopsonistic upstream market configuration, and increasing returns-to-scale …

Sequence Analysis Of Bacterial Dna In The Colon Of An Andean Mummy, Massimo Ubaldi, Stefania Luciani, Isolina Marota, Gino Fornaciari, Raul J. Cano, Franco Rollo

Biological Sciences

We have isolated DNA from 14 tissue samples from the internal organs of an Andean human mummy (10th–11th century A.D.) and have checked the persistence of the original human and bacterial templates using the following main approaches: 1) amino acid racemization test; 2) quantification of mitochondrial DNA copy number; 3) survey of bacterial DNA in the different organs; 4) sequence analysis of bacterial amplicons of different lengths. The results demonstrate that both the original human DNA and the DNA of the bacteria of the mummy gut are preserved. In particular, sequence analysis of two (respectively 100 and 196 bp in …

Cognitive And Affective Learning In The Basic Course: Effects Of Delivery Format, Immediacy, And Communication Apprehension, Susan J. Messman, Jennifer Jones-Corley, David Mezzacappa, Deborah J. Crusan

English Language and Literatures Faculty Publications

A quasi-experimental design was used to investigate changes in learning outcomes for students enrolled in large-lecture/break-out sections versus in self-contained sections of the basic communication course.More precisely, the study explores the relationship between communication apprehension, immediacy and learning outcomes for the two class formats.Results indicate that students' cognitive learning outcomes are slightly higher in the large-lecture/break-out sections versus self-contained sections. In addition, affective learning decreases for all students from the first day of class and slightly more for students in the large-lecture/break-out sections. However, when the teacher is perceived as highly immediate, there is no difference in formats. (Contains 5 …

Dynamics Of Biomolecules: Assignment Of Local Motions By Fluorescence Anisotropy Decay, Carl N. Bialik, Barnabas Wolf, Edward L. Rachofsky, J. B. A. Ross, William Laws

Chemistry and Biochemistry Faculty Publications

Many biological systems have multiple fluorophores that experience multiple depolarizing motions, requiring multiple lifetimes and correlation times to define the fluorescence intensity and anisotropy decays, respectively. To simplify analyses, an assumption often made is that all fluorophores experience all depolarizing motions. However, this assumption usually is invalid, because each lifetime is not necessarily associated with each correlation time. To help establish the correct associations and recover accurate kinetic parameters, a general kinetic scheme that can examine all possible associations is presented. Using synthetic data sets, the ability of the scheme to discriminate among all nine association models possible for two …

Detection Of Silver In Metal-Poor Stars, James L. Crawford, Christopher Sneden, Jeremy R. King, Ann M. Boesgaard, Contantine P. Deliyannis

Publications

The resonance lines of neutral silver appearing at 3280, 3382 Å in the near-ultraviolet spectral region have been identified on Keck I HIRES spectra of four halo stars with metallicities -1.3 ≥ [Fe/H] ≥ -2.2. This represents the first detection in metal-poor stars of an element in the atomic number range 41 ≤ Z ≤ 55. The mean relative silver abundance is [Ag/Fe] +0.2, with little star-to-star variation. Silver abundance upper limits in three other metal-poor stars are consistent with this mean value. The modest overabundance of silver is similar to the overabundances in this metallicity range exhibited by other …

Trophectoderm Differentiation In The Bovine Embryo: Characterization Of A Polarized Epithelium., L C Barcroft, A Hay-Schmidt, A Caveney, E Gilfoyle, E W Overstrom, P Hyttel, A J Watson

Obstetrics & Gynaecology Publications

Blastocytst formation is dependent on the differentiation of a transporting epithelium, the trophectoderm, which is coordinated by the embryonic expression and cell adhesive properties of E-cadherin. The trophectoderm shares differentiative characteristics with all epithelial tissues, including E-cadherin-mediated cell adhesion, tight junction formation, and polarized distribution of intramembrane proteins, including the Na-K ATPase. The present study was conducted to characterize the mRNA expression and distribution of polypeptides encoding E-cadherin, beta-catenin, and the tight junction associated protein, zonula occludens protein 1, in pre-attachment bovine embryos, in vitro. Immunocytochemistry and gene specific reverse transcription--polymerase chain reaction methods were used. Transcripts for E-cadherin and …
