Improved Virus Isoelectric Point Estimation By Exclusion Of Known And Predicted Genome-Binding Regions, Joe Heffron, Brooke Mayer Dec 2020

Improved Virus Isoelectric Point Estimation By Exclusion Of Known And Predicted Genome-Binding Regions, Joe Heffron, Brooke Mayer

Civil and Environmental Engineering Faculty Research and Publications

Knowledge of the isoelectric points (pIs) of viruses is beneficial for predicting virus behavior in environmental transport and physical/chemical treatment applications. However, the empirically measured pIs of many viruses have thus far defied simple explanation, let alone prediction, based on the ionizable amino acid composition of the virus capsid. Here, we suggest an approach for predicting the pI of nonenveloped viruses by excluding capsid regions that stabilize the virus polynucleotide via electrostatic interactions. This method was applied first to viruses with known polynucleotide-binding regions (PBRs) and/or three-dimensional (3D) structures. Then, PBRs were predicted in a group of 32 unique viral …


Study The Effect Of Damping Change During The Dynamic Analysis Of A Reinforced Concrete Bridge With Neoprene Cushions, Mais Ghassoun Aug 2020

Study The Effect Of Damping Change During The Dynamic Analysis Of A Reinforced Concrete Bridge With Neoprene Cushions, Mais Ghassoun

Emirates Journal for Engineering Research

The damping ratio has a important effect on the dynamic behavior of the bridges. and it is customary when designing to assume it as a predetermined fixed value independent of the response amplitude and frequency of the structure . A lot of experimental research worked on identifying them, but the dependence of damping and other dynamic characteristics of vibration amplitudes and their impact on responses and the results of the analysis need more scrutiny and simulation due to the difficulty of conducting vibration experiments for structures of realistic dimensions and large weights such as a RC bridge, which necessitated a …

Model Development To Assess Groundwater Flooding And Levee Underseepage In New Orleans, Louisiana, Shuo Yang Mar 2020

Model Development To Assess Groundwater Flooding And Levee Underseepage In New Orleans, Louisiana, Shuo Yang

LSU Master's Theses

Flooding is a major threat to New Orleans due to its geographic location and geologic condition. However, potential groundwater flooding is seldom studied and poorly understood even though groundwater level is expected high in the city. High groundwater level might result in groundwater flooding in low-lying areas. High uplift pore water pressures may cause strong underseepage and risk levee safety. The objective of this study is to assess the impacts of hydrogeology on groundwater flooding and evaluate potential underseepage-induced hazards along levees in New Orleans. In this study, a groundwater flow model development which involves stratigraphy modeling, groundwater flow model …
