Paleoenvironmental analysis of Cretaceous mudstones at Slope Mountain, Alaska using carbon stable isotopes

This project uses field samples, microfacies analysis, and carbon stable isotopes of mudstones to determine past environmental conditions of North Slope, Alaska during the Albian-Cenomanian (Cretaceous). Samples were taken at Slope Mountain, Alaska located north of the Brooks Range. Slope Mountain includes the Torok Formation and the upper and lower Nanushuk Formations that consist of alluvial, deltaic, and shallow marine facies that were deposited into the North Slope foreland basin on the Arctic Alaska micro plate. An exhaustive search for identifiable microfossils, such as pollen, diatoms, and foraminifera in the samples yielded nothing but charcoal and carbon residue. No other fossilized material was identified. Carbon stable isotope values are consistent with a mix of algae and terrestrial plants, suggesting deposition in a shallow marine setting close to shore

Mating Behavior of the European Corn Borer, Ostrinia nubilalis (Hubner)

The European corn borers for this study were raised on artificial diet. The adult moths were placed in cage for mating and their behavior was observed. The moths’ day-night cycle was reversed so that work with cinematography could be done in a darkened room during the day. Mating crosses were made between male and female adult moths from Minnesota, New York, and Wisconsin strains. The moths’ mating behavior is described and the crossing of geographical strains is documented

Business linguistics in internal communications

The language used in internal communication is an inadequately researched topic that has the potential to impact nearly every working adult. Business linguistics are proven to affect external communications (Danyushina, 2011). Research shows that specific language evokes different emotions (Danyushina, 2011). This research discusses possible associations between internal communications, business linguistics and employee engagement by replicating the inductive study, Danyushina (2011) and applying the methodology to internal communications. The goal is to understand if language used in internal communications to employees impacts overall employee engagement. Other goals of this research are to address how present the key themes of internal communication are in the corporate rhetoric of four corporations that represent the corporate scene as a whole, if corporate rhetoric in internal communications changes dependent on the industry category of a corporation, and if corporate rhetoric in internal communications changes dependent on the publication category of a sample. Companies can utilize this research to improve the effectiveness of their internal communications

Elucidation Of Protein Interactions And The Re-Tuning Of Porphyrin Electronics For Hydroxylases

Non-Ribosomal Peptide Synthetases (NRPSs) and their exogenous tailoring partners have been heavily studied but not in the context of non-cognate systems. Orf78, a dinuclear iron β-hydroxylase from the lysobacter pathway and homologous to CmlA from the chloramphenicol pathway, is used to test affinities for one native and two non-native T-domains. Results indicate that there is enough difference between Type I and Type II NRPS systems to disfavor common recognition motifs. Additionally, the β-hydroxylase P450sky, from the skyllamycin biosynthetic pathway, is used in conjunction with the NRPS ATdomain NikP1AT from the nikkomycin biosynthetic pathway, in lieu of the homolog P450nikQ. The second portion of the thesis will discuss the creation of a sustainable source of biodiesel products are currently a goal of ‘green’ programs. The fatty acid decarboxylase P450olet uses the cheaply obtainable hydrogen peroxide as the oxidant to achieve a high-valent iron species. Substitution of the iron for manganese in the porphyrin scaffold raises the redox potential and forms a Mn(IV)-oxo complex that is too weak to perform C-H bond abstractions. Alternatively, substitution of the iron-protoporphyrin IX with ironmesoporphyrin IX lowers the redox potential, increasing the amount of hydroxylated fatty acid at lower carbon chain lengths but also leads to a decrease in the efficiency in multiple turnover reactions

3D Applications in Conservation and Connoisseurship: Investigating and Supplementing the Scholarly Catalogues of the Red Faun

Focusing on the Capitoline Red Faun, this paper concerns the 3-dimensional digital model (3DDM) and its potential utility in creating accurate conservation condition reports. Tradition condition reports verbally express information about the state of a work of art, such as its preservation or past restorations, and are often supplemented with photographs or drawings. The various historical catalogues that have appraised the condition of the Capitoline Red Faun, more aptly referred to as “scholarly catalogues” demonstrate the potential for ambiguity within this practice; of the five accounts appraising the state of the Red Faun, no two agree on which parts are ancient and which belong to the eighteenth-century restorations of Bartolomeo Cavaceppi and Clemente Bianchi. Given that this sculpture is included within the art historical canon of Hellenistic sculpture, a new condition report is timely. This paper undertakes an exhaustive analysis of the various joins and offers another condition report, this one illustrated with an interactive, annotated 3DDM. When served to the public and scholars alike, these interactive condition reports can act as a critical tool, garnering interest in and facilitating re-appraisals of status such as the Capitoline Red Faun
