The Power Of Water: Examining Ice Crystal Nucleation’S Impact On Cloud Thermodynamic Properties, Caleb Wood Dec 2018

The Power Of Water: Examining Ice Crystal Nucleation’S Impact On Cloud Thermodynamic Properties, Caleb Wood

Meteorology Senior Theses

Cloud systems demonstrate great influence on Earth’s climate with both radiative and precipitation processes. However, detailed convection can be poorly represented in global climate models. By resolving fine-scale features, like cloud ice crystal nucleation, an improved understanding of the microphysics involved with deep convection will aid to more accurate incorporations of cloud systems into climate models. The purpose of this study is to analyze the differences in certain cloud thermodynamic properties, including mixing ratios and latent heat budgets, as a result of various ice nucleation cases. The Clark-Hall Cloud-Resolving Model (CRM) was initialized with observations from the 1997 Atmospheric ...

Synthesis Of Peg-Modified Guanine For Modulation Of Transcription Via Xpt-Pbux Riboswitch, Leah Santana Dec 2018

Synthesis Of Peg-Modified Guanine For Modulation Of Transcription Via Xpt-Pbux Riboswitch, Leah Santana

Senior Projects Spring 2019

Riboswitches are RNA molecules which respond to specific stimuli by turning on or off transcription or translation. The aptamer domain of the xpt-pbuX riboswitch in B. subtilis has a three-dimensional structure with a specific binding site for guanine. When guanine is bound, the expression platform forms a three-dimensional structure which inhibits transcription of downstream purine synthesis genes. In this work, polyethylene glycol (PEG) was conjugated to position nine of guanine. This will potentially increase the solubility of guanine in solvents such as dimethyl sulfoxide, making it easier to use for assays. The PEGylated guanine will be used to probe the ...


Gerrymandering And The Impossibility Of Fair Districting Systems, Danielle Degutz Dec 2018

Gerrymandering And The Impossibility Of Fair Districting Systems, Danielle Degutz

Senior Projects Spring 2019

Voting district boundaries are often manipulated, or gerrymandered, by politicians in order to give one group of voters an unfair advantage over another during elections. To make sure a system of voting districts is not gerrymandered, the population size, the shape, and the voting efficiency of each party in each district should be taken into consideration. Following recent work of Boris Alexeev and Dustin G. Mixon, we discuss mathematical criteria for each of these three aspects, and we prove how problems arise when attempting to apply all three at once to a districting system--first to a simplified districting system and ...


A View From Within: Notes And Insight From An Institutional Ethnography Of The National Commission For Natural Protected Areas In Tulum, Mexico, Maxwell J. Martin Dec 2018

A View From Within: Notes And Insight From An Institutional Ethnography Of The National Commission For Natural Protected Areas In Tulum, Mexico, Maxwell J. Martin

Graduate Masters Theses

National parks and protected areas are an integral component of the Mexican government’s long-term natural resource conservation strategy. They comprise over 90 million hectares throughout the country. However, the establishment and upkeep of these protected areas often incites conflict both between and among local actors. From poachers taking protected resources to indigenous peoples exercising their rights, protected areas have become a source of political, economic, and moral contention across the globe. In addition, their effectiveness in either ecological or sustainable development terms has been ambiguous at best.

Tulum, Mexico exemplifies this dilemma. The site of pre-Columbian Mayan architecture, Tulum ...

An Acoustic Monitoring Method For Assessing River Dolphin Presence And Changes In The Context Of Anthropogenic Development, Charles A. Muirhead

Graduate Masters Theses

Populations of river dolphins throughout Asia are in decline as a direct result of intensified anthropogenic activity along river systems. Water development projects, land use change, contamination, and intensified fishing practices are known factors contributing to the probable extinction of the Yangtze river dolphin (Lipotes vexillifer) and declining populations of the South Asian river dolphin (Platanista gangetica spp.), Irrawady dolphin (Orcaella brevirostris), and finless porpoise (Neophocaena a. asiaeorientalis). Although not yet as extensive, river system development in South America is following a similar path as that of Asia, with impacts on dolphin species likely to follow. Currently, the Amazon river ...


Application Of Graphical Models In Protein-Protein Interactions And Dynamics, Amir Vajdi Hoojghan Dec 2018

Application Of Graphical Models In Protein-Protein Interactions And Dynamics, Amir Vajdi Hoojghan

Graduate Doctoral Dissertations

Every organism contains a few hundred to thousands of proteins. A protein is made of a sequence of molecular building blocks named amino acids. Amino acids will be referred to as residues. Every protein performs one or more functions in the cell. In order for a protein to do its job, it requires to bind properly to other partner proteins. Many genetic diseases such as cancer are caused by mutations (changes) of specific residues which cause disturbances in the functions of those proteins.

The problem of prediction of protein binding site is a crucial topic in computational biology. A protein ...

Chemistry & Biochemistry Faculty Works

J-aggregates of anionic meso-tetrakis(4-sulfonatophenyl)porphyrin form at intermediate pH (2.3–3.1) in the presence of NiSO₄ or ZnSO₄ (ionic strength, I.S. = 3.2 M). These aggregates convert to monomeric porphyrin units via metallation with copper(II) ions. The kinetics for the disassembly process, as monitored by UV/vis spectroscopy, exhibits zeroth-order behavior. The observed zeroth-order rate constants show a two-term dependence on copper(II) ion concentrations: linear and second order. Also observed is an inverse dependence on hydrogen ion concentration. Activation parameters have been determined for the disassembly process leading to ΔH^≠ = (+163 ± 15) kJ·mol ...

The Impact Of The Implementation Of Temporary Import Procedure On Electronic Products: Input--Output Analysis, Dedi Abdul Hadi, Toru Matsumoto

Journal of Environmental Science and Sustainable Development

Currently, imported electronic products enter the Indonesian market using general import procedures, where the importer has to pay the import duty and taxes in full rate. In the absence of proper recycling systems, the electronic products that have reached their end of life and those are no longer used, end up in the landfills. Some researchers found hazardous materials inside the electronic products that could contaminate water, soil and air. Therefore, another strategy is needed to avoid negative effects on the environment. The Temporary import policy is one of the import procedures under Customs administration control, which states that goods ...

Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara Dec 2018

Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara

Journal of Environmental Science and Sustainable Development

In many production systems, multiple products are interactively produced. Therefore, an innovative technology that leads to changes in parts of such systems may influence both the unit environmental impacts associated with the products, and the productivity of multiple products. To compare alternative technologies on a common basis, we often account for the avoided or supplemented emissions associated with the residual (i.e. surplus and supplemented) products produced from within the considered system boundary. In this study, using an example of an innovative technology envisioned for use in sugar mills, we first demonstrate how comparisons can be made when the systems ...
