▼ The presence and flow of moisture degrade engineering properties of asphalt concrete as part of thermodynamic, chemical, physical, and mechanical processes. This detrimental effect is referred to as moisture
damage. The aim of this dissertation is the development of physically based constitutive relationships along with a computational tool for the fundamental analysis of combined mechanical and moisture induced
damage of asphalt concrete. Such a tool can greatly contribute to an improved material selection procedure and give insight into the various
damage inducing mechanisms in asphalt concrete.
In this dissertation, thermo-hygro-mechanical constitutive relationships are developed based on the principle of virtual power and laws of thermodynamics in order to simulate moisture-induced
damage of asphalt concrete. An evolution function is proposed to consider the detrimental effect of moisture diffusion and presence inside the material. The effect of pore water pressure is incorporated using Biot???s coefficient. The Continuum
Damage Mechanics (CDM) theory is extended to Continuum Moisture-Mechanical
Damage Mechanics (CMMDM) to incorporate the moisture degradation effect and couple it to the mechanical response of asphalt concrete. The proposed moisture
damage constitutive relationships are implemented in the Pavement Analysis using Nonlinear
Damage Approach (PANDA) finite element (FE) package to model the moisture
damage effect on the complex environmental-mechanical response of asphalt concrete. The developed constitutive relationship and framework are validated over different loading scenarios and a range of experimental measurements.
The developed constitutive relationship and framework are applied to simulate pavement performance. The focus is on investigating the effects of various moisture conditioning periods on permanent deformation (rutting) and fatigue
damage of asphalt pavements.
The constitutive and computational models are used to develop a framework for the simulation of the effect of moisture on the microstructural response of asphalt concrete. This framework explicitly incorporates the material microstructural distribution and properties. The developed framework is used to perform two-dimensional (2D) and three-dimensional (3D) micromechanical simulations in order to study and investigate the capability of the proposed constitutive relationships to predict the microstructural response of asphalt concrete under combined effect of moisture diffusion and mechanical loading.

▼ M.S. University of Hawaii at Manoa 2011.
Little is known about the molecular mechanism of γ-H2AX in DNA damage response in mammalian embryos when compared to the somatic cells. An integrative review of the literature on the molecular mechanism of γ-H2AX in DNA damage response in somatic cells and in mammalian embryos was performed. The objective of the study is to summarize and synthesize the published databased literature over the last 10 years on molecular mechanism of γ-H2AX in mouse pre-implantation embryos and somatic cells using the key words – "γ-H2AX", "DNA damage", "somatic cells", "mouse embryo". An initial medline search was performed using our inclusion and exclusion criteria and then expanded by snowballing. The articles were compiled in the form of a Review Matrix.
The knowledge gap was investigated and the conceptual model was formulated to hypothesize the sequence of DNA damage responses occurring during the time of early mouse embryogenesis. Major themes drawn from the studies are-1). Periodic appearance and disappearance of γ-H2AX in early mouse pre-implantation embryos, 2) Development of γ-H2AX foci in the pronuclei without imposing any replicative stress on the mouse embryo, 3) Occurrence of γ-H2AX in the S-phase of somatic cells under replicative stress and normal embryos, 4) Prevalence of prominent γ-H2AX signal in male pronuclei compared to the female pronuclei during mouse embryogenesis. The study will also show scopes of future research to explore the arena in clinical context.

▼ Colloidal gas aphrons (CGAs) recently used as part of
water-based drilling fluids have been found effective in
controlling the filtration rate by bridging the pores of the
reservoir rock and therefore, reducing the formation damage. This
research aims to generate colloidal gas aphrons (CGA) in oil based
drilling fluids; to study stability, rheology and the filtration
loss characteristics of CGAs and to investigate formation damage
properties of CGAs as a drilling fluid. Aphrons were generated in
mineral oil using a polymer-surfactant mix. Based on how changing
the polymer and surfactant concentration affects the
physico-chemical characteristics of the fluid, an optimum
formulation for the aphron drilling fluid was suggested. The
stability of microbubbles was investigated by looking at the
effects of time, temperature and pressure on the aphron yield and
bubble size distribution. Effects of temperature and pressure on
the density of the oil-based aphron fluids have been investigated.
Based on the PVT analysis results, an equation of state was
proposed. Finally, the performance of the oil-based aphron fluid in
porous media was investigated. The effects of changing the CGA
fluid injection rate, the type of saturating fluid and the
wettability of the porous media on the pressure drop were examined.
An assessment of the formation damage following the oil-based CGA
fluid injection was also made.

▼ This thesis demonstrates the effect of micro-
damage healing on stress and displacement fields in the vicinity of a crack tip in the material that tend to self-heal. The micro-
damage healing model is modeled by incorporating time-dependent traction within the crack faces. This time-dependent traction occurs in a small zone referred to as healing process zone. The effect of the micro-
damage healing on crack propagation in elastic media is investigated by deriving analytical relations for Stress Intensity Factor (SIF) when micro-
damage healing mechanism is in effect. It is shown that the larger values of both healing process zone and bonding strength decrease the value of SIF near the crack tip. In order to clearly capture this phenomenon, a novel technique based on complex variables is used to derive the equations to calculate the stress and displacement fields in elastic media. Using the third correspondence principle, which is suitable in analyzing the crack shortening (healing phenomenon), the corresponding results of stress and displacement fields in elastic media are converted into viscoelastic media. Since asphalt has time-dependent material properties, the viscoelastic result is more accurate than the elastic. It is shown that an increase in the value of both healing process zone and bonding strength results in a decrease in the stress and displacement fields near the crack tip. Finally, the effect of using different coefficients in defining the bonding strength and relaxation time is evaluated.
Asphalt concrete pavements are concurrently subjected to mechanical and environmental loading conditions during their service life. Applied mechanical and environmental loadings gradually degrade properties of asphalt concrete pavements. However, under specific conditions, asphalt concrete has the potential to heal and regain part of its strength. Identifying a model for the healing process is crucial. This proposed model is not dependent on the test methods that empower its usage in computational modeling. Moreover, this research considers both effects of instantaneous healing (a result of wetting) and time-dependent bond strength (a result of molecular diffusion between the crack faces), using the complex-variable method. Schapery (1989) considered only instantaneous healing and regarded it as the total bond strength. Therefore, considering both effects of instantaneous and time-dependent bond-strength makes this model superior with respect to the analogous model. It is hoped that this research provides insight on the healing mechanism at micro-scale.

▼ It is important to assess and communicate the risk to life and downtime associated with earthquake induced
damage to structures. Thus, a previously developed four-diagram/four-step approach to assess direct losses associated with structural
damage, a similar quantitative risk assessment technique is used to examine the indirect loss associated with death and downtime. The four-step approach is subdivided into four distinct tasks: (a) Hazard analysis, (b) Structural analysis, (c) Loss analysis of both direct and indirect losses and (d) The total loss estimation due to
damage, death and downtime. This empirically calibrated model in the form of power curve is used by establishing losses corresponding to onset of
damage state 5 (complete
damage) and limiting upper losses. The utility of the approach is investigated for the bridges in both California and New Zealand regions with different detailing. Results show that death related losses for bridges are generally twice and downtime five times the direct
damage losses. Thus, it is concluded that structures should be designed for more than just acceptable physical
damage. It is shown that a marked improvement can be made by moving to a comprehensive
damage avoidance design paradigm.

▼ Tremendous amount of oil and gas products are transported in pipeline worldwide giving rise to a demand to identify the hazards and evaluate the associated risk. Third-party intrusion is usually one of the least factors being considered during the pipeline hazard assessment stage despite the substantial portion contributing to the total number of oil and gas pipeline incident. This is because of the probabilistic risk assessment defect that makes it hard to model human actions and cannot be applied to intentional acts. Due to the distinctive motivations of third-party
damage, an unintentional third-party
damage Bayesian Network model and a game-theoretic model on malicious intrusion will therefore be built, respectively to examine the mechanism of pipeline failure caused by this mode.
This study is conducted aiming at investigating pipeline risk resulting from third-party
damage, and will formulate risk assessment models to identify threats, prioritize risks and determine which integrity plan should apply to different pipeline segments given the condition of third-party interference (both the accidental
damage and malicious acts). In other words, it can help to anticipate an optimal planning of the in-line inspection intervals which can decrease the risk of the pipeline to an acceptable level and achieve cost-effective pipeline integrity management.

▼ Formation
damage due to iron precipitation continues to be a major problem in the oil field. Research has established that as the pH of injected acid increases, iron (III) ions start to precipitate and block the pores in the formation, significantly reducing production. However, where exactly this iron precipitates and how iron precipitation changes with different lithologies has not yet been comprehensively studied.
Coreflood experiments were conducted on carobonate (calcite and dolomite) and sandstone cores to assess the effects of temperature and iron concentrations on the degree of
damage caused by iron precipitation during an acid job. The temperature values tested were 200 and 300°F. Iron concentrations ranging from 5,000 to 10,000 ppm were used. The core effluent samples were analyzed by ICP (Inductively Coupled Plasma) to measure the concentrations of key cations.
Coreflood experiments, revealed that iron precipitates across the entire core. Iron precipitation was severely detrimental in sandstone cores compared to those composed of calcite and dolomite. While limestone cores showed the least formation
damage from iron precipitation, coreflood tests indicated that as the iron concentration increases, the
damage was more evident. On the other hand, increasing the temperature adversely affected sandstone and dolomite cores, but improved the final permeability of limestone cores.
In this study, the location of the iron precipitation is determined for three different lithologies. The effects of different parameters are studied to determine the best conditions that would lead to a decrease in iron precipitation and hence prevent formation
damage. Iron control agents are not always needed, as previously thought.

▼ This work aims to improve the predictive capability for fiber-reinforced polymer matrix composite laminates using the finite element method. A new tool for modeling composite
damage was developed which considers important modes of failure. Well-known micromechanical models were implemented to predict material values for material systems of interest to aerospace applications. These generated material values served as input to intralaminar and interlaminar
damage models. A three-dimensional in-plane
damage material model was implemented and behavior verified. Deficiencies in current state-of-the-art interlaminar capabilities were explored using the virtual crack closure technique and the cohesive zone model. A user-defined cohesive element was implemented to discover the importance of traction-separation material constitutive behavior. A novel method for correlation of traction-separation parameters was created. This new
damage modeling tool was used for evaluation of novel material systems to improve
damage tolerance. Classical laminate plate theory was used in a full-factorial study of layerwise-hybrid laminates. Filament-wound laminated composite cylindrical shells were subjected to quasi-static loading to validate the finite element computational composite
damage model. The new tool for modeling provides sufficient accuracy and generality for use on a wide-range of problems.

▼ This thesis is dedicated to the development of new technologies for sweep improvement due to plugging of highly permeable channels and layers by injected or lifted or mobilized fines particles. The following methods of improved waterflood have been proposed in the thesis:
• Injection of raw or poorly treated water with consequent homogenization of the injectivity profile due to distributed along the well skin factor.
• Injection of low salinity or fresh water resulting in lifting of reservoir fines, their migration and further capture by the rock with permeability reduction and redirection of the injected water into unswept area.
• Injection of sweet water into watered-up abandoned wells during pressure blowdown in oil and gas reservoirs with strong water support.
In the above three cases, the proposal of the new technologies was backed by detailed reservoir simulations. In all cases, the application of the proposed improved oil recovery technology, as forecasted by reservoir simulation, leads to 3-15% of incremental recovery and 2-3 times decrease of the amount of produced and injected water. The technology of raw water injection was developed using Eclipse waterflood BlackOil simulator with modelling of injectivity decline along the well due to plugging of porous media by injected particles. A new numerical procedure describing skin growth with time in each section of long horizontal wells have been developed and implemented into BlackOil Eclipse model. Different configurations of horizontal injectors and producers have been modelled resulting in production forecast with raw waterflooding.
The technology of low salinity water injection have been developed using Eclipse reservoir modelling with polymer injection option, which can describe mobilization of fines particles, their migration, capture and subsequent permeability decline. The main physics mechanism of incremental oil recovery found is the diversion of the injected water into unswept zones due to plugging the swept zone by capture particles. The incremental recovery, as obtained by reservoir simulation, is 12%. It may also result in 2 to 3 times decrease in water injection and production. The proposal of a new technology of small bank of fresh water injection into watered-up and abandoned production wells result in lifting of reservoir fines,
their migration and plugging the path for invaded aquifer water. It results in decrease of water production and prolongation of oil or gas production from wells.

▼ Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study into
damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear
damage accumulation hypothesis, is predictive of fatigue failure in bone. An electromagnetic shaker apparatus was constructed to conduct cyclic and variable amplitude tests on bovine bone specimens. Three distinct
damage regimes were observed following fracture. Fractures appeared ductile from low cyclic amplitude (< 4,000 με), brittle, from high cyclic amplitude (> 9,000 με), and a combination of ductile and brittle from mid-range cyclic amplitudes (6,500 – 6,750 με). Brittle and ductile fracture mechanisms were isolated into variable amplitude loading tests. PMR predictions of cycles to failure consistently over-predicted fatigue life when mixing isolated fracture mechanisms. However, PMR was not proven ineffective when used with a single
damage mechanism.

▼ Research on the origin of biological life on Earth is actively working toward understanding the conditions under which possible prebiotic chemical reactions could promote abiogenesis. Cyclobutane pyrimidine dimer (CPD) is the main reaction product of UVB-induced photochemistry on DNA. The presence of a wall, behind which DNA is encapsulated, serves as a necessary boundary and energy exchange system between the interior of a cell and surrounding environment. It is presently undetermined how primitive genetic polymers were protected on early Earth, but naturally occurring molecules present >3.4 Ga ago may have had a role. At that age, the synthesis of organic monomers likely occurred at interfaces between energy and environment. The reducing atmosphere (electron rich) enabled molecules to gain electrons to transduce energy. Since modern membrane-bound molecules that contribute to the movement of electrons in photosynthesis - and have energy transducing properties - contain conjugated ring systems, (PAH) polycyclic aromatic hydrocarbons may have exerted a prebiotic role in redox chemistry. This work aimed to evaluate the effect of a cell model (a vesicle) containing a possible primitive chromophore (here, pyrene) on DNA mutagenesis. An immunochemical assay was used to detect CPDs, formed between adjacent thymine nucleobases on fragmented genomic DNA and induced by UVB light, when DNA was encapsulated in a membrane composed of phospholipid alone or phospholipid and pyrene. These simulations were compared to DNA not encapsulated in a membrane. Results demonstrate that higher overall detection of CPD-DNA correlates with a greater initial rate of CPD-DNA formation. Mainly, the largest rate corresponded to DNA in solution, while the slowest rate corresponded to DNA encapsulated within a (DOPy) DOPC + pyrene membrane.

▼ Various aspects of rotator cuff tears have been studied in depth, including the primary pathogenesis and mechanical properties. There is, however, a lack of information available on the injury mechanics associated with sudden torque loading of the shoulder. To investigate the mechanical response of the Supraspinatus tendon and the joint capsule when exposed to repeated near-instantaneous torques, an in vitro test apparatus was developed. Supraspinatus and capsular reaction forces, capsular surface strains, and shoulder accelerations were measured over 30 cycles of applied torque. A decreasing logarithmic decay was found in the difference between the initial and final loads within each cycle. A generalized force-displacement fiber recruitment model was used to determine the protective role of the capsule by evaluating changes in stiffness. The results suggest that while relatively more
damage happens in the first few high-torque load cycles, sudden adduction loading injuries are likely fatigue-based in nature.

The roles of postsynaptic density-95 interactors in dendrite development and recovery after traumatic brain injury.

▼ Postsynaptic density 95 (PSD-95) is the major scaffolding protein at excitatory synapses, and it plays a major role in synaptic plasticity. Furthermore, PSD-95 and its interactor, cytosolic PSD-95 interactor (cypin), regulate dendrite branching by altering microtubule dynamics. Additionally, other PSD-95 binding proteins, end-binding protein 3 (EB3) and adenomatous polyposis coli (APC), promote microtubule bundling and stabilization. Thus, PSD-95 and binding partners may regulate the dendritic arbor during development and after injury.
I first addressed the role of cypin in the brain in vivo. While generating cypin knockout mice, I identified a novel short isoform of cypin, termed cypinS, which also binds to PSD-95 and regulates dendrite branching, although an increase in dendrites occur more distal from the soma when cypinS is overexpressed compared to when cypin is overexpressed. In addition, unlike cypin, cypinS does not have guanine deaminase activity. Overexpression of cypin, but not cypinS, decreases spine density, suggestingiv that the regulation of spine density but not dendrite branching by cypin is dependent on guanine deaminase activity. Furthermore, I have uncovered novel presynaptic roles for both isoforms as overexpression of either isoform leads to increases in miniature excitatory postsynaptic current (mEPSC) frequency. Thus, cypin and cypinS, play distinct roles in neuronal development.
I then chose to study the roles of PSD-95 and interactors in recovery after traumatic brain injury (TBI). We previously identified cypin as a novel target for TBI, and thus, here I studied the role of PSD-95 and its interaction with APC or EB3 in after injury induced by in vitro and in vivo models of TBI. I show that our in vitro model of mechanical stretch injury mimics moderate injury induced by controlled cortical impact (CCI) in mice. During the early stage (1-7 days) post-moderate CCI, the interaction of PSD-95 with APC and EB3 increases. Furthermore, downregulation of PSD-95 prevents stretch-injury mediated decreases in secondary dendrite number and total dendrite length, suggesting a required role of PSD-95 in injury-mediated insults to dendrites. Thus, PSD-95 may sequester APC and EB3 from microtubules to cause decreases in dendrite branching after TBI, and PSD-95 can be targeted as a novel approach for the treatment of patients with TBI.

▼ The exploration and exploitation of hydrocarbon wells should not cause any environmental hazards including contamination of groundwater (aquifers) and atmosphere. The cement placed in the annular gaps between the casing strings and the formation acts as a key barrier to provide zonal isolation and maintain the integrity of the wells. The integrity of the cement sheath and the cement sheath interfaces is susceptible to be compromised during well operational processes, including but not limited to, pressure integrity tests (PIT), completion operations, stimulation treatments, and production processes. The cement sheath may experience different types of mechanical
damage as a result of being exposed to these different wellbore operational procedures. Therefore, understanding of cement failure mechanisms is of the utmost importance for better assessments of wellbore integrity. This thesis demonstrates the results of the experimental-numerical studies and investigates the integrity of the cement sheaths subjected to pressure and temperature variations. The overall purpose of this study is to improve the modelling capabilities of cement sheath integrity assessments by employing a more comprehensive constitutive model for the cement sheath compared to the rest of the models previously used. The experimental studies on the behaviour of the cement-based specimens under compression tests showed a strong non-linearity in the obtained stress-strain curves which confirms the necessity of applying plasticity theories. However, it is hard to explain the elastic stiffness degradation of the cement-based materials which happens during experiments using the classical plasticity theories. Therefore, in this thesis, the modified Concrete
Damage Plasticity (CDP) model was employed, particularly formulated for modelling geo-materials such as rocks, concrete, and cementitious materials. The Concrete
Damage Plasticity is a continuum model which combines plasticity and
damage mechanisms, considering two different tensile and compressive state of
damage. The yield criterion in the CDP model also represents the pressure-dependency of the geo-material behaviour under shearing at different levels of confinement in addition to the incorporation of non-associated flow rule (material dilatancy). These features show the superiority of the CDP model for employing in cement sheath integrity assessments. However, the paucity of cement class G mechanical parameters, e.g. lack of experimental data under different confining pressure and tensile properties, was an impediment to the incorporation of Concrete
Damage Plasticity model. Therefore, the experimental aspect of this study intends to expand the cement class G inventory. The experimental data and analyses added to inventory are as followed. The investigations of curing temperature and pressure confinements effects on the strength and post-peak response of the cement class G under compression and also obtaining cement tensile properties. The experimental results show by increasing the curing…

▼ D.Litt. et. Phil.
Head injury is the major cause of death for individuals under 35 years old in the United States of America, and a similar picture exists in South Africa. A major cause of traumatic brain injury is motor vehicle accidents. In addition, the advances in modem medical technology increase the chances for survival, for example, sophisticated medical diagnostic techniques such as computerised tomography (CT), and magnetic resonance imaging (MRI). Advances in emergency trauma and neurosurgical procedures have also increased the number of survivors following a head injury. The symptoms resulting from head injury include disturbed physical, cognitive, psychological and behavioural functioning. Long-term management of these symptoms is usually required. A body of evidence exists that demonstrates the value of rehabilitation during the first year of recovery from traumatic brain injury. Head injury cases often result in litigation in that the injured person may be entitled to compensation for the injuries sustained. Considerable forensic debate exists around the issue of whether the victim's symptoms are attributable to organic brain damage, or whether they reflect a pre-existing functional psychological state of psychiatric illness, or personality disorder. Further still, the individual may be 'malingering' or faking postconcussion symptoms of headache, dizziness, fatigue, memory deficit, impaired concentration, irritability, anxiety, insomnia, concern about bodily functions, and hypersensitivity to light and noise. Alternatively, a common diagnosis is traumatic neurosis with a psychogenic basis, and in the context of litigation is referred to as "compensation neurosis". Specifically, the issue of contention revolves around concussion, and mild or minor head injuries. This study proposed that both neuropathophysiological and psychosocial symptoms occur in the event of a traumatic brain injury. This view supports the traditional model that pain or the sequelae of head injury are not affected by compensation. Therefore, the objective of the study was that follow-up assessment after compensation pay-outs should produce similar results to the assessment results obtained during the litigation process. The hypotheses of the study were essentially confirmed. The neuropsychological error scores produced in the assessments during litigation, and two-to-four years after the completion of litigation were similar. However, similar to other studies, variations were evident. Four exceptions were demonstrated in that significant improvement was evident with regard to shotterm verbal memory delayed recall for paragraphs, and for immediate recall (without and after interference) in verbal memory for a word list. These improvements therefore pertain to verbal memory. The fourth improvement occurred with respect to manual dexterity and visual-motor work speed, although the improvement may be peripheral or primary (neurological). Further findings included that no gender differences were evident in the neuropsychological…

▼ Color centers in CaF
2 were studied in this work, in parallel with examinations of changes in the refractive index of the crystals by the larger research group, after they were subjected to radiation. Color centers induced by gamma rays and in mixed neutron-gamma fields were studied in CaF
2 and LiF using transmittance and absorbance spectra. The goals were to examine both neutron and neutron-gamma mixed field irradiations to be able to isolate neutron only effects and to correlate these color center effects with refractive index effects studied by our larger collaboration. Irradiation sources include
137Cs, DD and DT reactions at Sandia National Laboratory, the University of New Mexico Neutron Howitzer, and the Oregon State University TRIGA reactor. Only the samples irradiated to high doses, 2.176x10
5 Gy through 2.176x10
7 Gy, at Oregon State University showed strong color centers. Different color centers had different intensities and the absorbance as a function of dose shows a clear relation and is dependent on the specific color centers. UV bleaching shows a similar relation in reverse.

▼ Approximately 12% of Americans do not consume the amount of zinc equal to the Estimated Average Requirement for zinc and could be at risk for marginal zinc deficiency. Zinc is an essential component of proteins in the defense against oxidative stress and DNA
damage repair. Specifically in the prostate, zinc concentrations are inversely associated with prostate malignancy. Zinc deficiency may predispose cells to the development of cancer by increasing oxidative stress and DNA
damage. Studies have shown that severe zinc-depletion increased DNA
damage in testes. However, the effects of marginal zinc deficiency, which is more prevalent in human population and physiologically relevant, are understudied. This study aimed to specify the mechanisms by which zinc status affects DNA integrity and the prostate maintains zinc level in vivo. We examined the effects of zinc deficiency on DNA
damage and oxidative stress in rat models and in human studies.
In rats, severe zinc-depletion caused an increase in DNA
damage in peripheral blood cells that decreased following zinc-repletion. DNA repair functions were impaired as indicated by compromised p53 DNA binding and differential activation of DNA repair proteins. Importantly, marginal zinc-depletion (MZD) also increased DNA
damage and oxidative stress, and impaired DNA repair functions. However, these effects were not observed in the prostate. Only in combination with an exogenous stress (exercise), MZD increased DNA
damage in the prostate, indicating that MZD may sensitize the prostate to exogenous DNA damaging agents.
Similar to the rat study, marginal dietary zinc depletion (6wk) in healthy males increased DNA strand breaks in peripheral blood cells, alterations which were ameliorated by zinc repletion (4wk). Oxidative stress and antioxidants were not altered during zinc depletion/repletion periods.
The increases in DNA
damage were associated with impaired zinc homeostasis. MZD decreased zinc concentration as well as ZnT2 expression in the prostate dorsolateral lobe, indicating disregulation of zinc transporter and zinc homeostasis.
Taken together, these studies suggest a key function of zinc in maintaining DNA integrity. Thus, the maintenance of adequate dietary zinc may have an important impact on protecting tissues, such as the prostate, from DNA
damage and decreasing cancer risk.

▼ Polycomb protein methyltransferase, Enhancer of Zeste
2 (Ezh2), is frequently overexpressed in human malignancy and is
implicated in cancer cell proliferation and invasion. Recently,
several other polycomb proteins have been implicated in modulating
the response to DNA double strand breaks, and thus we hypothesize
that Ezh2 is also involved in the DNA damage response pathway. We
investigated the involvement of Ezh2 and its associated complex,
polycomb repressive complex 2 (PRC2), in the DNA damage response
pathway. We found that PRC2 proteins recruit to sites of DNA damage
and knockdown of Ezh2 decreases double strand break repair
efficiency and increases cellular sensitivity to ionizing
radiation. Our data supports the hypothesis that PRC2 is involved
in the DNA damage response and contributes to DNA double strand
break signaling and repair.

Change in electrophysiological correlates of recognition memory processes following mild traumatic brain injury.

▼ There is a considerable body of evidence showing the presence of long term change in electrophysiological correlates of attentional processes following mild traumatic brain injury (MTBI). As well there is a large body of research demonstrating impairment in cognitive functioning, including memory and attention processes, in the acute stage following MTBI. However, to date there has been little research investigating long term change in electrophysiological correlates of memory function following MTBI. More specifically, there is virtually no research investigating long term change in electrophysiological correlates of recognition memory function following MTBI. Therefore the present research aimed to investigate the electrophysiological correlates of recognition memory processes in males who had suffered an MTI3I. Event related potentials (ERPs) were collected during the encoding phases and the recognition phases from three recognition memory paradigm experiments.
In Experiment 1, 22 males who experienced an MTBI 1 month prior, 21 males who experienced an MTBI 24 months prior, and 19 control group males completed two recognition memory tasks, one under deep and one under shallow Level-of-processing conditions, using low frequency nouns as stimuli. ERP data from the deep Level-of-processing encoding phase showed that the expected subsequent memory effect of greater mean amplitude (500-800ms) for subsequently remembered than subsequently missed studied words was present for the control group and the 24 month MTBI group, yet absent for the 1 month MTBI group. Recognition phase data showed that neither MTBI group displayed the implicit memory effect of greater mean amplitude (300-500ms) parietally for missed old words compared to unstudied words under shallow Level-of-processing conditions, whereas the control group did.
Experiment 2 employed the same experimental paradigm as Experiment 1 and involved MTBI participants from both MTBI groups from Experiment 1. Fifteen participants from the 1 month MTBI group completed the experimental tasks at approximately 7 month following Experiment 1 (labelled 'Time 2'), and 12 of these participants completed the experimental task a third occasion after a further 10 months (labelled 'Time 3'). Sixteen participants from the 24 month MTBI group completed the same experimental task approximately 13 months after Experiment 1 (labelled 'Time 2'). The results from the encoding phase of Experiment 2 showed that the 1 month MTBI group displayed a subsequent memory effect at Time 2. However, at Time 3 for the 1 month MTBI group and at Time 2 for the 24 month MTBI group, no subsequent memory effects were present due to an apparent increase in mean amplitude elicited by subsequently missed old words. These results suggest that there may be impairment or change in processes involved in encoding meaningful information which, over months and years following the acute post-injury phase, may lead to adaption in these processes. Within recognition phase data results from both MTBI groups showed an…

PERFORMANCE ANALYSIS AND RADIATION DAMAGE ESTIMATION OF

▼ The Mu2e experiment aims to search for the charged
lepton flavour violating (CLFV) process of a coherent,
neutrinoless, conversion of a muon into an electron within the
proximity of an aluminium nucleus. Mu2e seeks to measure the ratio
(R
μ e) of the rate of this conversion process, relative to
that of ordinary muon capture. Mu2e will achieve world-leading
sensitivity, improving the current limit of R
μ e <
7 × 10
-13(90%\,{{C.L.}}), set by the
SINDRUM-II experiment, by an order of 10
4. This corresponds to a
single-event sensitivity of R
μ e <
2.87 × 10
-17(90%\,{C.L.}). Many beyond Standard
Model (BSM) theories require CLFV to occur at a rate accessible by
Mu2e. Any observation of CLFV at Mu2e would have profound
implications on particle physics.\ The Stopping Target Monitor
(STM) will be comprised of both a HPGe and a LaBr3 detector which
will monitor the signals of photons produced in stopped-muon
processes to a required accuracy of 10%. To achieve the desired
sensitivity, it is imperative that the detectors perform at their
optimal level. The STM detectors are placed within a harsh
radiation environment in the form of a high energy `flash' of gamma
radiation as well as a flux of fast neutrons.\ Estimations of
radiation
damage to HPGe in literature is limited. This thesis
reports an approach which utilizes the Kinetic-Energy Released in
Matter (KERMA) parameter that considers the energy dependence of
the incident flux and the cross-section information for the
incident particle. Resampling schemes have been adopted to give a
realistic rate over the experiment run time. The results have then
been normalized to the radiation
damage caused by a {}
252Cf
source. \ The estimated time before annealing of the detector is
necessary is found to be 75 and 78~months in the case of
neutron
damage and τ ∼ 24~years, 11~months in the case of
electron/positron induced
damage. This shows significant
improvement on the previous estimations.

▼ The Large Hadron Collider (LHC) at CERN has the
highest energy and luminosity in the world. Radiation hardness is
then a critical requirement for the inner tracker design. The inner
tracker is important for identifying heavy quarks using high
spatial precision detectors. Silicon detectors are now the primary
technology for this application.3D silicon sensors use a novel
technology with penetrating electrodes and have excellent radiation
hardness by design. It overcomes the signal loss with a low
operation voltage by reducing the collection length compared to the
current planar technology used in the ATLAS pixel detector.The
ATLAS insertable B-layer (IBL) is an upgrade to improve tracking
resolution of the inner tracker and will be installed in 2013. It
will be composed of 75% planar sensors and 25% 3D sensors in the
large-η region. It is important to simulate the IBL tracking
performance and to have a valid model for 3D sensors.This thesis
investigated the experimental data for heavily irradiated planar
strip sensors and 3D sensors to develop a device simulator, in
which impact ionisation has to be included. The modelling has found
that the radiation induced effective doping concentration has two
linear regimes with a smaller growth rate at high fluences. This
shows the possibility to operate silicon sensors with a higher
irradiation level. %Avalanche effects have to be included in the
device simulation.The signal efficiency of each pixel is the basis
to simulate the whole IBL response. A model and a code were
developed to calculate the induced signal from electron-hole pairs
generated by the traversing charge particles. This results in a 2D
efficiency map used as an input of the 3D digitiser for the Geant4
simulation. This map was adopted by the IBL software team for the
whole tracker simulation and has been validated by the test beam
data.

▼ The preservation of DNA replication is requisite for cellular integrity and prevention of tumor formation and cell death. The Y-family DNA polymerases (Pol eta, kappa, iota, and REV1) are crucial in this process because of their roles in the replication and bypass of DNA lesions and adducts. DNA-peptide crosslinks (DPCs) are formed through the bioactivation of bis-electrophiles such as ethylene dibromide. These electrophiles can bind both peptide and protein targets such as glutathione and alkylguanine DNA-alkyltransferase (AGT) with DNA. Studies has shown that these DPCs are mutagenic as well as cytotoxic to cells. Our hypothesis is that select translesion DNA polymerases are capable of replicating past DNA-peptide cross-links. For this replication to occur, SPRTN (a nuclear protease) will degrade the crosslinked protein to a smaller peptide to allow the DNA polymerase to proceed. Model peptides of varying lengths from the AGT active site, as well as glutathione, were synthesized to determine if the size of the peptide crosslink affects the replication by Y-family DNA polymerases. Results showed that Pol eta was capable of bypassing each of the peptide crosslinks, albeit with low levels of misincorporation and significantly reduced catalytic efficiency. SPRTN was also found to proteolytic degrade AGT crosslinks on DNA, and this degradation does allow replication past the lesion by Pol eta.

▼ Phosphors have been used for radiation detection before, but only for non-ionizing radiation. In fact, many phosphors are designed to be radiation-resistant so they can be used long-term and in harsh environments unaffected. Furthermore, many of the phosphors used in radiation environments are subjected to ionizing radiation. Our goal, however, is to find a material that changes permanently by non-ionizing radiation and that can be used as a record for radiation exposure. Ideally the material will be sensitive to a wide range of fluences as well as selective to different types and doses of radiation exposure. To determine if radiation can
damage phosphors, we systematically exposed several materials to x-rays, alpha particles, protons, and neutrons. We expect radiation to cause displacement dam- age and change the structure of the material. Since phosphor luminescence intensity and lifetime are mainly governed by the arrangement of luminescent centers in the host lattice and the local crystal environment of each luminescence center, the optical properties can be used to detect these structural changes. The results of these experiments provide insight into the possible mechanisms of
damage and instruct how to adjust our approach to developing a material with the desired interactions with radiation.

▼ The ends of chormosomes are capped by telomeres, which distinguish the termini from damaged DNA. Paradoxically, DNA repair proteins are also required for telomere maintenance. How DNA repair pathways are regulated to maintain telomeres while remaining competent to repair DNA
damage throughout the genome is unknown. In this dissertation, I used a genetic approach to investigate how critical components of telomerase and the telomere protein complex interact with the DNA
damage response (DDR).
In the flowering plant, Arabidopsis thaliana telomeres are bound by the CST (CTC1/STN1/TEN1) heterotrimer. Loss of any CST component results in telomere shortening, telomere fusions, increased G-overhang length and telomere recombination.
To understand the phenotypes caused by CST deficiency, I examined telomeres from plants lacking CTC1 or STN1 and TERT or KU. My analysis showed that CST acts in a separate genetic pathway for telomere length regulation from both KU and TERT. Further, I found that KU and CST act in separate genetic pathways for regulation of G-overhang formation. These demonstrate that multiple pathways are used to maintain telomere length and architecture in plants.
My study of the interaction of telomere components with the DDR revealed ATR promotes genome stability and telomere length maintenance in the absence of CTC1, probably by activating programmed cell death of stem cells with high amounts of DNA
damage. I also found that poly(ADP-ribosylation) is not required for maintenance of Arabidopsis telomeres, in contrast to human telomeres.
Finally, I found an unexpected connection between the DDR and telomerase. My research showed that ATR maintains telomerase activity levels. Further, induction of double- stranded DNA breaks in seedlings led to a rapid decrease in telomerase activity, which correlated with increased abundance of TER2, an alternate Arabidopsis telomerase RNA. I hypothesize that TER2 inhibits telomerase to prevent its inappropriate action at internal sites in chromosomes. These data reveal two ways that DDR pathways work in concert with telomerase to promote genome integrity.

▼ In order to obtain a better understanding the complex mechanical behavior of asphalt binder, its microstructure must be examined. In addition, the interrelationship between asphalt binder microstructure,
damage, and mechanical properties must also be determined. In this work the unique relationship between asphalt binder microstructure and damaging mechanisms is established. Here, the AFM is used to image the microstructure of two different types of asphalt binders. A micrometer driven mechanical device named a "Micro-Loading Frame" is used to obtain AFM images of bitumen surface after subjecting it to high levels of tensile strain. Using image analysis techniques the microstructural changes due to the applied tensile strain is established. Furthermore, using a specific AFM creep indentation protocol the viscoelastic properties of asphalt binder are extracted for each microstructural phase observed. In addition, this concept was applied to rolling thin film oven test (RTFOT) aged and pressure aging vessel (PAV) aged binders. The geometry obtained from AFM imaging combined with the microrheology obtained from AFM creep indentation experiments were used to construct finite element simulations examining local stress distributions. The numerical solutions were compared to experimental observations.
Using AFM imaging technique three unique phases were found within the asphalt binder at the micron length scale i.e. bee, bee casing, and interstitial. All three phases were found to have uniquely different viscoelastic properties. Finite element analysis results showed that heterogeneity within the asphalt binder led to localized stress amplification. Application of high levels of tensile loads resulted in phase separation and cracking referred to as load induced phase separation (LIPS) zones. The occurrence of the LIPS zones were primarily found to be within interstitial regions. Application of tensile strains also resulted in the reduction of the number of bee structures, and also the area occupied by the bee structures. The location of LIPS zones coincided with the location high stress zones determined using the finite element simulations suggesting the possibility of phase separation and cracking occurring due to localized high stresses. Application of tensile strains to RTFOT, and RTFOT+PAV aged samples also resulted in the formation of LIPS zones within the interstitial regions. However, an increase in the level of aging the led to a reduction of LIPS zone formations for the same level of applied tensile displacements.
The effect of geometry of asphalt binder microstructure on the mechanical response was determined. An increase in the area fraction of the bee/bee casing phase, a reduction in the distance between adjacent bee/bee casing features led to an increase in the maximum stress magnitudes. An increase in the number of bee/bee casing features led to a reduction in the maximum stress magnitude when the area fraction was kept constant.

▼ The impact of radiation-induced effects on the properties of alloys fabricated using additive manufacturing (AM) was evaluated through the implementation of ion beam irradiation testing followed by electron backscatter diffraction (EBSD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), nanoindentation, scanning probe microscopy (SPM), and transmission electron microscopy (TEM). Inconel 600 (I600) and 316L stainless steel (316L) rods were fabricated by Quad City Manufacturing Laboratory in collaboration with Lockheed Martin for this study. The rods were produced in three distinct orientations (vertical, horizontal, and 45°) using laser additive manufacturing (LAM). Conventionally manufactured I600 and 316L rods were purchased from Metal Samples, Inc. to enable comparative studies. The I600 and 316L LAM specimens were heat treated to 900 °C and 650 °C in argon with no cold working, respectively. Similarly, the conventionally manufactured I600 and 316L control specimens were cold rolled and annealed at 980 °C and 1040 °C in argon with no cold working, respectively.
XRD of unirradiated specimens showed differences in peak ratios between build orientations, indicating anisotropic grain structures for samples fabricated by LAM. All LAM rods contained significantly fewer coincidence site lattice (CSL) boundaries and more residual strain compared to the controls before and after irradiation, regardless of build direction, as determined by EBSD. Material performance parameters such as resistance to radiation-enhanced embrittlement, corrosion, creep, intergranular stress corrosion cracking, and hydrogen-induced cracking were inferred from CSL theory, which suggests that all LAM rods are more susceptible to grain boundary-related failure mechanisms than their conventionally manufactured counterparts. All alloys built by LAM are strongly textured with parallel to the build direction before and after irradiation. Directionally dependent Taylor Factor distributions suggest that resistance to slip depends on build direction where, from highest to lowest resistance: horizontal > 45° > vertical.
All I600 samples experienced radiation-induced segregation which, according to SEM/EDS and SPM studies, resulted in the formation of chromium carbide precipitates on to the irradiated surfaces. Strong anisotropic mechanical behavior was observed in the LAM rods, as measured by nanoindentation and bulk tensile testing. The hardness of the unirradiated as-annealed specimens, from greatest to least, is: horizontal > 45° > vertical. The radiation-induced hardening of LAM specimens, from greatest to least, is: horizontal > 45° > vertical. The orientation dependence of radiation-induced segregation and hardening mechanisms is discussed.
The ultimate outcome of this work is a first-of-a-kind high-dose radiation
damage study of alloys fabricated by LAM, revealing that the radiation-induced changes in material properties for these alloys is dependent upon build orientation.

▼ The deleterious effect of moisture on the structural integrity of asphalt mixtures has been recognized as one of the main causes of early deterioration of asphalt pavements. This phenomenon, usually referred to as moisture
damage, is defined as the progressive loss of structural integrity of the mixture that is primarily caused by the presence of moisture in liquid or vapor state. Moisture
damage is associated with the development of different physical, mechanical, and chemical processes occurring within the microstructure of the mixture at different intensities and rates. Although there have been important advancements in identifying and characterizing this phenomenon, there is still a lack of understanding of the
damage mechanisms occurring at the microscopic level. This situation has motivated the research work reported in this dissertation.
The main objective of this dissertation is to formulate and apply a numerical micromechanical model of moisture-induced
damage in asphalt mixtures. The model focuses on coupling the effects of moisture diffusion—one of the three main modes of moisture transport within asphalt mixtures—with the mechanical performance of the microstructure. Specifically, the model aims to account for the effect of moisture diffusion on the degradation of the viscoelastic bulk matrix of the mixture (i.e., cohesive degradation) and on the gradual deterioration of the adhesive bonds between the aggregates and the asphalt matrix (i.e., adhesive degradation).
The micromechanical model was applied to study the role of some physical and mechanical properties of the constitutive phases of the mixtures on the susceptibility of the mixture to moisture
damage. The results from this analysis suggest that the diffusion coefficients of the asphalt matrix and aggregates, as well as the bond strength of the aggregate-matrix interface, have the most influence on the moisture susceptibility of the mixtures.
The micromechanical model was further used to investigate the influence of the void phase of asphalt mixtures on the generation of moisture-related deterioration processes. Two different probabilistic-based approaches were used to accomplish this objective. In the first approach, a volumetric distribution of air voids sizes measured using X-Ray Computed Tomography in a dense-graded asphalt mixture was used to generate probable void structures in a microstructure of an asphalt mixture. In the second approach, a stochastic modeling technique based on random field theory was used to generate probable air voids distributions of the mixture. In this second approach, the influence of the air voids was accounted for by making the physical and mechanical properties of the asphalt matrix dependent on probable voids distributions. Although both approaches take into consideration the characteristics of the air void phase on the mechanical response of the mixtures subjected to moist environments, the former explicitly introduces the air phase within the microstructure while the latter indirectly includes its effects…
