Understanding the response of cancer cells to ionising radiation is a crucial step in modern radiotherapy. Raman microspectroscopy, together with Partial Least Squares Regression (PLSR) analysis has been shown to be a powerful tool for monitoring biochemical changes of irradiated cells on the subcellular level. However, to date, the majority of Raman studies have been performed using a single spectrum per cell, giving a limited view of the total biochemical response of the cell. In the current study, Raman mapping of the whole cell area was undertaken to ensure a more comprehensive understanding of the changes induced by X-ray radiation. …

Occupational Hazard Identification And Health Risk Assessment Of Volatile Organic Compounds Exposure In Plastic Recycling Plants In Thailand: Case Studies Of Polypropylene And Polyethylene, Muhammed Ayaj Ansar
Chulalongkorn University Theses and Dissertations (Chula ETD)
Mechanical recycling in small scale plastic recycling plants in Thailand with mechanical and thermal driven stages may lead to various occupational hazards. This study aimed to improve occupational safety and health (OSH) by reducing these risks to acceptable levels from hazard identification and risk assessments which were mainly associated with indoor volatile organic compounds (VOCs) exposure. Accordingly, heat, noise, and VOCs were identified as potential hazards in the hazard identification from four selected small-scale plastic recycling plants in Thailand with polypropylene (PP) and polyethylene (PE) recycling practices. In exposure assessment, almost all the exposure levels of heat stress exceeded the …

Enrichment, Characterization And Application Of Bacterial Consortia For Degrading 2-Mercaptobenzothiazole In Rubber Processing Wastewater, Saowaluk Krainara
Chulalongkorn University Theses and Dissertations (Chula ETD)
Benzothiazoles is widely used as vulcanized accelerator in rubber industry. The high volume of 2-MBT usages resulted in its release into the environment and can cause adverse health impacts. This study aimed to obtain efficient 2-MBT-degrading bacteria for wastewater application. The bacterial consortia were enriched by incubating rubber wastewater sludge in a medium containing 2-MBT for 28 days followed by a stepwise acclimation by gradually increasing 2-MBT concentrations in an NH4Cl-containing medium for 76 days. The process significantly increased the bacterial number and changed the dominant populations and degradative genes. Among these consortia, the EN consortium had the highest specific …
Application Of Boolean Logic To Natural Language Complexity In Political Discourse, Austin Taing
Application Of Boolean Logic To Natural Language Complexity In Political Discourse, Austin Taing
Theses and Dissertations--Computer Science
Press releases serve as a major influence on public opinion of a politician, since they are a primary means of communicating with the public and directing discussion. Thus, the public’s ability to digest them is an important factor for politicians to consider. This study employs several well-studied measures of linguistic complexity and proposes a new one to examine whether politicians change their language to become more or less difficult to parse in different situations. This study uses 27,500 press releases from the US Senate between 2004–2008 and examines election cycles and natural disasters, namely hurricanes, as situations where politicians’ language …
Prompt Fission Neutron Energy Spectrum Of N+235U, Jason M. Mcginnis
Prompt Fission Neutron Energy Spectrum Of N+235U, Jason M. Mcginnis
Theses and Dissertations--Physics and Astronomy
Despite nuclear fission prominence in nuclear physics, there are still several fundamental open questions about this process. One uncertainty is the energy distribution of neutrons emitted immediately after fission. In particular the relative energy distribution of neutrons above 8~MeV has been difficult to measure. This experiment measured the prompt neutron energy spectrum of n+235U from 3-10~MeV. The measurement took place at Los Alamos National Laboratory (LANL) and used a double time-of-flight technique to measure both the beam and fission neutron kinetic energies. Fission event timing was measured with a parallel plate avalanche counter. The fission neutron time-of-flight was …
A Detection And Data Acquisition System For Precision Beta Decay Spectroscopy, Aaron P. Jezghani
A Detection And Data Acquisition System For Precision Beta Decay Spectroscopy, Aaron P. Jezghani
Theses and Dissertations--Physics and Astronomy
Free neutron and nuclear beta decay spectroscopy serves as a robust laboratory for investigations of the Standard Model of Particle Physics. Observables such as decay product angular correlations and energy spectra overconstrain the Standard Model and serve as a sensitive probe for Beyond the Standard Model physics. Improved measurement of these quantities is necessary to complement the TeV scale physics being conducted at the Large Hadron Collider. The UCNB, 45Ca, and Nab experiments aim to improve upon existing measurements of free neutron decay angular correlations and set new limits in the search for exotic couplings in beta decay. To …
Ε-Superposition And Truncation Dimensions In Average And Probabilistic Settings For ∞-Variate Linear Problems, Jonathan M. Dingess
Ε-Superposition And Truncation Dimensions In Average And Probabilistic Settings For ∞-Variate Linear Problems, Jonathan M. Dingess
Theses and Dissertations--Computer Science
This thesis is a representation of my contribution to the paper of the same name I co-author with Dr. Wasilkowski. It deals with linear problems defined on γ-weighted normed spaces of functions with infinitely many variables. In particular, I describe methods and discuss results for ε-truncation and ε-superposition methods. I show through these results that the ε-truncation and ε-superposition dimensions are small under modest error demand ε. These positive results are derived for product weights and the so-called anchored decomposition.
Effect Of Hydrogen Exposure On The Electronic And Optical Properties Of Insulating Titanates, John G. Connell
Effect Of Hydrogen Exposure On The Electronic And Optical Properties Of Insulating Titanates, John G. Connell
Theses and Dissertations--Physics and Astronomy
Hydrogen exposure of insulating d0-titanates, such as SrTiO3 (STO), has displayed the formation of intriguing conducting states. These conducting states form through the use of forming gas (N2/H2) annealing or hydrogen plasma exposure, where hydrogen gas is exposed to high energy microwaves. The exposure of STO to hydrogen causes metallic conductivity due to the introduction of hydrogen cations on some of the oxygen sites. However, the optical properties of this hydrogen-exposed STO have not been well-studied. Further, Ba0.5Sr0.5TiO3 (BST), an insulating dielectric, also shows changes in its conductivity …

Confprofitt: A Configuration-Aware Performance Profiling, Testing, And Tuning Framework, Xue Han
Theses and Dissertations--Computer Science
Modern computer software systems are complicated. Developers can change the behavior of the software system through software configurations. The large number of configuration option and their interactions make the task of software tuning, testing, and debugging very challenging. Performance is one of the key aspects of non-functional qualities, where performance bugs can cause significant performance degradation and lead to poor user experience. However, performance bugs are difficult to expose, primarily because detecting them requires specific inputs, as well as specific configurations. While researchers have developed techniques to analyze, quantify, detect, and fix performance bugs, many of these techniques are not …

Magnetic Field Monitoring In The Sns Neutron Edm Experiment, Alina Aleksandrova
Theses and Dissertations--Physics and Astronomy
It is a well known fact that the visible universe is made almost entirely of baryonic matter. Yet, this is also one of the greatest puzzles that physicists are trying to solve: Where did all of this matter come from in the first place? The Standard Model (SM) of particle physics predicts a baryon asymmetry that is much smaller than what is observed in nature. In order to try and explain this discrepancy, Sakharov (1967) postulated three necessary conditions for baryogenesis in the early universe. One of these is the requirement that charge conjugation (C) and the product of C …
A Machine Learning Approach To Artificial Floorplan Generation, Genghis Goodman
A Machine Learning Approach To Artificial Floorplan Generation, Genghis Goodman
Theses and Dissertations--Computer Science
The process of designing a floorplan is highly iterative and requires extensive human labor. Currently, there are a number of computer programs that aid humans in floorplan design. These programs, however, are limited in their inability to fully automate the creative process. Such automation would allow a professional to quickly generate many possible floorplan solutions, greatly expediting the process. However, automating this creative process is very difficult because of the many implicit and explicit rules a model must learn in order create viable floorplans. In this paper, we propose a method of floorplan generation using two machine learning models: a …
