Role Of Microtubules In Budding Yeast Cytokinesis, Su Young Park

Masters Theses

"Cytokinesis is an important step to finish cell cycle events and separate into two daughter cells. This event is driven by actomyosin ring contraction. In budding yeast, the mitotic exit network (MEN) controls completion of ana/telophase by signaling events. Bub2 is a mitotic exit network regulator and binds to Tem1p which is an important component in MEN. Mad2 is a component of a separate spindle checkpoint. Mad2 dependent pathway prevents the metaphase to anaphase transition under spindle damage. Because yeast cells have cell walls, septum formation follows actin ring contraction. Here it was investigated how microtubule defects affect cytokinesis in …

Friction Stir Spot Welding Of Aluminum Alloys, Wei Yuan

Masters Theses

"Efforts to reduce vehicle weight and improve safety performance have resulted in increased application of light-weight aluminum alloys and a recent focus on the weldability of these alloys. Friction stir spot welding (FSSW) is a solid state welding technique (derivative from friction stir welding (FSW), which was developed as a novel method for joining aluminum alloys). During FSSW, the frictional heat generated at the tool-workpiece interface softens the surrounding material, and the rotating and moving pin causes material flow. The forging pressure and mixing of the plasticized material result in the formation of a solid bond region. The present work …

A Study Of The Relationship Between Semiotic Content In Commercial Email Subject Lines And The Decision By The Recipient To Open The Message, Stephen J. Johnson

Masters Theses

The writings of Saussure, Peirce, Barthes, Eco and others express theories that symbols, signs, and signals are integral elements in the assignation of meaning within general human communication. Email marketing specialists such as Stephanie Miller, Andy Goldman, and Jeannieay Mullen opine that it is the email recipient’s inferences regarding the words in the address or subject lines that are the primary determinants in the decision whether or not to first open and subsequently respond to a commercial email. It would then seem that email marketers would be well served by understanding what forms these inferences in the minds of the …

Ending Conflict: Raising The Costs Of Defection In African Failed States, Brian Crisher

Masters Theses

This paper views the civil conflicts in African failed states through the lens of game theory. From the numerous peace agreements and cease-fires that have been broken in these conflicts, it is clear that defecting from such agreements,is often more profitable than abiding by them. Why is this so? Furthermore, what can be done to raise the costs of defection and therefore promote cooperation amongst the fighting parties? This paper proposes that the international community has the ability to do just this through one-sided intervention.

"Bird In A Cage:" Exploring Transnational Immigrants' Identity Negotiations, Ewa Urban
