Understanding The Effect Of Adaptive Mutations On The Three-Dimensional Structure Of Rna, Justin Cook

Undergraduate Research and Scholarship Symposium

Single-nucleotide polymorphisms (SNPs) are variations in the genome where one base pair can differ between individuals.¹ SNPs occur throughout the genome and can correlate to a disease-state if they occur in a functional region of DNA.¹According to the central dogma of molecular biology, any variation in the DNA sequence will have a direct effect on the RNA sequence and will potentially alter the identity or conformation of a protein product. A single RNA molecule, due to intramolecular base pairing, can acquire a plethora of 3-D conformations that are described by its structural ensemble. One SNP, rs12477830, which …

Preferential Vaporization Potential Of Crude Oils And Its Impact On Flame Flashback Behaviors, Ayuob Al Wahaibi

Theses and Dissertations

As combined cycle gas turbines for power generation operating on light distillate fuels provide a sufficient energy, there is a global trend in using heavy liquids (e.g. HFO, crude oils) for direct-firing in gas turbine. However, using these heavy fuels imposes many challenges due to their wide range of physical/chemical properties, which control near-limit combustion behaviors, such lean blow-out and flashback. In addition, the ignition propensity of these heavy fuels is not reported in crude assays, and utilizing a simple, with small sample, and quick methodology to characterize the ignition propensity is important in determining the fuel quality.

Impact Of Urban City Sprawl On The Identity Of Suburbs And Rural Areas, Fadi Nasreddine

Architecture and Planning Journal (APJ)

Urban sprawl is the rapid expansion of the city towards the suburbs and the countryside, and it happens for various reasons. The first one is of residential nature, and is a result of growing population density while others are of political, economic, and social nature. There is no doubt that the city's encroachment towards the countryside and the emergence of new patterns of construction such as buildings and transportation networks have more drawbacks than advantages, in developing countries, especially in the absence of planning. This phenomenon causes the rise of real estate prices that leads to a change in the …
