Scripture for America: Scriptural Interpretation in John Locke's Paraphrase

Description: Is John Locke a philosopher or theologian? When considering Locke's religious thought, scholars seldom point to his Paraphrase and Notes on the Epistles of St. Paul. This is puzzling since the Paraphrase is his most extensive treatment of Christian theology. Since this is the final work of his life, did Locke undergo a deathbed conversion? The scholarship that has considered the Paraphrase often finds Locke contradicting himself on various theological doctrines. In this dissertation, I find tha… more

Computational Studies of C-H Bond Activation and Ethylene Polymerization Using Transition Metal Complexes

Description: This work discusses the C-H bond activation by transition metal complexes using various computational methods. First, we performed a DFT study of oxidative addition of methane to Ta(OC2H4)3A (where A may act as an ancillary ligand) to understand how A may affect the propensity of the complex to undergo oxidative addition. Among the A groups studied, they can be a Lewis acid (B or Al), a saturated, electron-precise moiety (CH or SiH), a σ-donor (N), or a σ-donor/π-acid (P). By varying A, we seek… more

Defining Components Linked to Bacterial Nutritional Utilization of Cyanide as a Sole Nitrogen Source

Description: One of the challenges in biology is placing a function on the myriad of gene sequences having become available from rapid advances in genome sequencing. One such example is a gene cluster (Nit1C) found in bacteria that is tied to the unusual ability of certain bacteria to grow when supplied cyanide as the sole nitrogen source. The term cyanotrophs has been applied to such bacteria, for which a genetic linkage between cyanotrophy and Nit1C was demonstrated for 10 separate bacteria. In additio… more
