Understanding Retroviral Replication: Roles Of Nucleocapsid And Rnase H During Reverse Transcription In Vivo., Wen-Hui Zhang Jan 2002

Understanding Retroviral Replication: Roles Of Nucleocapsid And Rnase H During Reverse Transcription In Vivo., Wen-Hui Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Retroviruses exhibit high genetic variability, which is generated by mutations and recombination during viral replication. This can lead to rapid emergence of viral variants resistant to antiretroviral drugs. A better understanding of retroviral replication may lead to the development of improved antiviral drug therapy and effective vaccines to retrovirus-related diseases. The fact that retroviral nucleocapsid protein (NC) is multifunctional and plays crucial roles in viral replication makes it a good target for antiviral drug development. By studying how NC affects reverse transcriptase (RT) template switching, the in vivo role of NC during reverse transcription can be explored. Using a sensitive …

Building The Beaver And Lake Erie Canal: The Politics Of Public Improvements In Pennsylvania, 1783-1845., William David Mccarthy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patterns of commerce and settlement in colonial America were shaped by watercourses and portages. Road building skills were primitive and boating represented the most effective means of moving bulk freight and passengers. Traders and frontiersmen leading the advance of European settlement into the Appalachian Mountains therefore adopted the shortest crossings between watersheds. Natural conditions in Pennsylvania did not promote an orderly advance westward and produced isolated clusters of settlement around Philadelphia and Pittsburgh, with small and widespread settlements in Northwest Pennsylvania. State leaders were hard pressed to define the limits of Pennsylvania until the end of the eighteenth century, and …

A Comparative Study Of Shrinkage And Cracking Of High-Performance Concrete Mixtures For Bridge Decks., Jennifer Lynne Morris Jan 2002

A Comparative Study Of Shrinkage And Cracking Of High-Performance Concrete Mixtures For Bridge Decks., Jennifer Lynne Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

To alleviate the deterioration of concrete structures, High-Performance Concrete (HPC) is extensively used, particularly for bridge decks, due to its favorable durability characteristics. However, there is a problem with the high cracking tendency of HPC due to its high early shrinkage, low water-cementitious ratio, brittleness and low creep. Thus, the HPC advantages of high compressive strength and low permeability are somewhat offset by cracking problems, which reduce the service life of bridge decks. To improve this problem, the goal of this study is to modify conventional HPC mixtures with admixtures or modifiers to obtain low-cracking or no-cracking formulations using West …
