▼ Depletion forces were used to separate an equinumber density binary dispersion of 1.5 and 0.82 µm polystyrene sulfate (PS) particles. Experiments consisted of injecting a pulse of a binary dispersion of PS particles into the inlet of a packed bed of 0.5 mm silica collector beads. Prior to injection, a carrier fluid of either KCl and KOH electrolyte or a silica nanoparticle dispersion was flowing through the column at steady state. When the carrier fluid was a dispersion of silica nanoparticles, the ratio of PS particles in the column outlet would change from 1:1 big to small particles to slightly over 2:1. This implies that more of the smaller 0.82 µm particles were being trapped on the surface of the collector beads due to
depletion forces. Experiments with a single particle type (either 1.5 or 0.82 µm PS particle) were also done and correlated with the binary dispersion measurements. Potential energy profiles between a PS particle and a flat silica plate were calculated. The secondary energy barrier for the 1.5 µm particles was two times greater than for the 0.82 µm particles. Hence, the 0.82 µm particles were more likely to overcome the energy barrier and get trapped on the surface of the collector beads. Although the potential energy profiles were calculated at equilibrium, they can be used as a tool in finding the optimal conditions for separation.

▼ A study site in the Luangwa district, south-eastern part of Lusaka Province was used for an investigation of the impact of human activities on indigenous woody vegetation.Evidence obtained from the review of literature and initial field reconnaissance suggested that the observed changes and variations in woody plant communities was directly or indirectly related to human activities rather than natural changes or differences in topography.Woody vegetation changes as a result of the varied human activities which identified from the review of relevant literature, aerial photographs, topographical maps and field reconnaissance undertaken in August 1981. During the period December 1981 and January 1982, the impact of the varied human activities on indigenous woody vegetation was investigated in the field. Since it was not possible to examine the indigenous woody vegetation in the entire study area due to time limitations five sample quadrats were examined for each identified major activity.The vegetation in each selected quadrat was examined in terms of species composition, structural damage as a result of the activity under consideration and the number of individuals in different size groups.This information was supplemented by that which was obtained from a selected number of households. Information from the 50 households was obtained through questioning and discussions and measurements were taken wherever possible.The human activities which were considered included; cultivation, fuel wood collection, bush burning, timber exploitation for building purposes and grazing and browsing of domesticated animal Measures were taken whenever possible to estimate quantitatively the total cleared area or corresponding clear-felled area as a result of the varied human activities. The result obtained showed that the varied human activities have led to a gradual transformation of the indigenous woody vegetation. Some of the above listed activities especially charcoal burning and arable agriculture have altered the woody vegetation of the affected areas through continuous clear-cutting.The study also revealed that the study area is experiencing a steadily increasing rural population. This increase in human population is placing more pressure on the woodland due to increase demand for arable land and woodland resources. Thus vegetation degradation has started in most parts of the study area where people have gathered in large groups to form villages. It must however be noted that, the little evidence gathered from the study suggest that vegetation destruction appears to have originated from a recent history of regressive changes which have continued to the present day.Most of the changes in indigenous woody vegetation can be considered to be related to population increases since areas where population is high the demand for woody resources such as fuelwood and polewood is high and generally appears to exceed local supplie Generally, it can be postulated that the study area as a whole is still underpopulated in the sense of…

The drying of the Arkavathy river: understanding hydrological change in a human-dominated watershed.

▼ Human interventions in the hydrologic cycle have intensified to the extent that water resources cannot be managed and understood in isolation from anthropogenic influences. New approaches are needed to understand the effects of humans on hydrology, especially in regions of the world with limited hydrologic records. This dissertation focuses on a case study of the Arkavathy watershed adjacent to Bangalore, India, which has been transformed by rapid urbanization, intensification of agriculture, and over-exploitation of water resources over the last 50 years. During this time, the disappearance of streamflow in the watershed was largely overlooked as Bangalore shifted from Arkavathy-sourced water supply to imported water and farmers from surface water to groundwater irrigation. With Bangalore continuing to expand its water footprint and local groundwater resources drying up, moving towards sustainable water resources management in the Arkavathy requires overcoming the general absence of local hydrological records to develop an understanding of the changing hydrology of the watershed. To this end, a multifaceted research approach is developed and applied to the Arkavathy watershed to identify the dominant hydrologic dynamics within the watershed and understand the conditions under which hydrologic change occurred. This research reveals a number of important findings. First, humans are the primary drivers of change in this watershed, as neither precipitation variability nor increases in temperature can explain the observed changes in hydrology. Second, hydrologic change within the watershed is spatially heterogeneous, with drying occurring in the northern part of the watershed and increased surface water availability downstream of Bangalore. Third, streamflow decline in the northern Arkavathy has most likely been caused by extensive groundwater depletion driven by groundwater irrigated agriculture. And finally, management strategies designed to reverse groundwater depletion by constructing check dams within the surface water network are unlikely to succeed on the scales pertinent to watershed management. In addition to understanding water resources within the Arkavathy, this work serves as a foundation for understanding the trajectory of water resources in the region. This research also presents an approach for investigating historical hydrologic change in a poorly monitored watershed, understanding human-water interactions, and supporting long-term predictions for sustainable water management.

▼ Exploring Microglial Homeostasis and Repopulation Dynamics Using Colony-Stimulating Factor 1 Receptor InhibitionByAllison Rachel NajafiDoctor of Philosophy in Biological Sciences University of California, Irvine, 2017Associate Professor Kim Green, ChairMicroglia are the primary immune effector cells in the CNS, responsible for the majority of inflammatory responses in the brain. Microglial homeostatic signals and replicative properties are largely unknown - however, early studies indicate that microglial turnover is low and proliferation is rare (Lawson et al., 1992), which could result in the acquisition of age-related deficiencies and senescence. As microglia age they become dysregulated, exhibiting an altered inflammatory profile, reduced phagocytic efficiency, and impaired migratory abilities (Godbout and Johnson, 2004; Frank et al., 2006; Damani et al., 2011; Njie et al., 2012). Given the dysregulation of aged microglia, activation of these cells could incite a chronic self-perpetuating cycle of inflammation and toxicity, contributing to neuronal death. We have recently discovered that microglia are fully dependent upon colony stimulating factor-1 receptor (CSF1R) signaling for their survival in the adult brain, and through the administration of small molecule inhibitors of the CSF1R, we have previously demonstrated we can eliminate >99% of all microglia brainwide (Elmore et al. 2014). Furthermore, my data show that the microglia-depleted brain has a profound ability to repopulate with new cells once CSF1R inhibitors are withdrawn, indicating that microglial elimination is fully reversible. The goal of my dissertation is to determine the source and properties of repopulated microglia in order to establish whether these cells can be used for potential therapeutic purposes – either to resolve chronic neuroinflammatory processes or, more ambitiously, to reverse microglial senescence in the aged brain. Indeed, I have discovered that microglial repopulation arises both from nestin+ progenitor cells and surviving microglia in the adult brain. To assess the regenerative capacity of these progenitor cells, I treated mice with multiple cycles of CSF1R inhibition followed by withdrawal of inhibitors - each cycle consists of 7 days of inhibition followed by a 7- or 28-day withdrawal period. These studies determined that there is a limited capacity for microglial repopulation. However, this capacity can be expanded by increasing recovery time between cycles. In addition, by increasing the exposure to CSF1R inhibitors, I have found that I can eliminate 100% of microglia from the adult brain, and that this results in a drastically altered repopulation pattern. Not only is the number of returning Iba1+ cells greatly diminished following complete microglial ablation, but cells initially only appear in white matter tracts along the rostral migratory stream (RMS) and projecting axons, and at early timepoints do not express the microglia-specific marker P2ry12. Eventually, these Iba1+ cells spread throughout the brain parenchyma,…

▼ In this research, the phase behavior of rod like nano
crystalline cellulose (NCC) suspensions has been investigated. NCC
suspensions with concentration at 1-4wt.% exhibited isotropic
behavior,a mixture of isotropic-nematic behaviorat 4 - 6wt.%, and
nematic phase behaviorat 7- 10wt.%. Then, both phase and
rheological behaviors of NCC suspensions were investigated in the
presence of polymers such as hydroxyethyl cellulose (HEC), dextran,
and carboxymethyl cellulose (CMC) solutions. HEC revealed
noticeable impact on phase behavior and induced depletion
interaction in NCC-HEC mixtures. Dextran, because of its branched
structure did not show thickening behavior in NCC-dextran mixtures.
Light polarization and rheological tests showed that CMC can also
induce depletion interaction in NCC-CMC mixtures. The effect of
ionic strength was also studied by adding NaCl in CMC
solutions.Increasing NaCl concentration caused considerable
variation in rheological behavior of the samples and they turned
into gel-like samples at high NaCl concentrations.

▼ Abnormal regulation of mitochondrial deoxyribonucleoside triphosphate pools can lead to mitochondrial DNA
depletion syndromes, a set of genetic diseases associated with
depletion of mitochondrial DNA. Besides mitochondrial DNA
depletion syndromes, improper maintenance of mitochondrial deoxyribonucleoside triphosphate pools and mitochondrial DNA have also been implicated in a host of other human pathologies. The unifying objective of this dissertation was to enhance our knowledge of the regulation of mitochondrial deoxyribonucleoside triphosphate pools. The first step was to investigate the characteristics of mitochondrial and cytoplasmic deoxyribonucleoside triphosphate levels. I calculated mitochondrial and cytoplasmic deoxyribonucleoside triphosphate concentrations from previously published data. Cytoplasmic and mitochondrial deoxyribonucleoside triphosphates are strongly correlated in normal cells but not in transformed cells. Following up this discovery with analysis of gene expression, I discovered that, consistent with the trends in deoxyribonucleoside triphosphate concentrations in cells, genes coding for enzymes that maintain cytoplasmic and mitochondrial deoxyribonucleoside triphosphates have correlated expression across normal tissues but not across transformed tissues. To further understand the influence of cytoplasmic deoxyribonucleoside triphosphates on mitochondrial deoxyribonucleoside triphosphates, I simulated the metabolism of mitochondrial deoxyribonucleosides with a computational model. Cytoplasmic deoxyribonucleotides have a substantial and indispensable contribution to mitochondrial deoxyribonucleoside triphosphates in most circumstances. My results further show that import from the cytoplasm would need to occur at either deoxyribonucleoside diphosphate or triphosphate levels.

▼ Conventional pumping test theories such as Theis solution often assume a horizontally isotropic media. Horizontal anisotropy exists in certain aquifer settings and its impact on pumping tests is not clearly demonstrated before, particularly when the aquifer is bounded by a stream. In this thesis, based on a newly developed mathematical model for pumping tests in a horizontally anisotropic aquifer bounded by a stream, the corresponding interpretation procedures will be illustrated. Stream
depletion will be calculated as a result of stream bank pumping based on the new model as well. The results of this research reflect that (1) aquifer parameters derived from newly developed interpretation methods are acceptable in the range of allowable error; so these methods can be used in practical field experiment; (2) with the increase of Ta/Tb, stream
depletion rate under the steady state also increases where Ta and Ta are the major and minor principal transmissivity values ( Ta>Tb); (3) when the angle between the X axis and the direction of Ta increases from 0 to pi/2, stream
depletion increases, where the X-axis is one of the working coordinate; conversely, when such an angle increases from pi/2 to pi, stream
depletion decreases. This research is expected to fill the gap of knowledge on present stream-aquifer interaction and pumping test theories for aquifers.

▼ Acidified dairy products are one of the oldest types of food products. Unfortunately all of them are low in dietary fibre. Thus, to improve health benefit of these products the idea of fortifying them with dietary fibre seems attractive. However dairy products enriched with Glucagel (a commercial product that is high in barley β-glucan) were found to suffer from textural defects. When the Glucagel concentration exceeded a certain value (5 g/L), dramatic phase separation was observed in set yogurt and yogurt drink with volume fraction of casein micelles greater then 0.108. To investigate interactions of β-glucan polymers and casein micelles in the milk prior to setting of yogurt, mixtures of yogurt milk and Glucagel were systematically studied. Depending on the volume fraction of casein micelles and the Glucagel concentration, a stable phase or a gel or a sedimented material could exist. The driving force for phase separation was
depletion flocculation of casein micelles in the presence of β-glucan. The phase separation responsible for textural defects in yogurt systems supplemented with high amounts of Glucagel can be avoided by the reduction of β-glucan molecular weight, a process that limits the range of attraction between micelles. Incubation of Glucagel with lichenase for 90 min resulted in homogeneous (stable) yogurt systems with Glucagel concentrations as high as 10 g/L.

▼ This work takes a closer look at ceria catalyst synthesis through micelle self-assembly. We compare surfactants, precursors, solvent systems, and doping. The surfactants are the building blocks upon which the ceria can crystallize. The samples are calcinated to test their thermal stability. Characterization is performed using pXRD as well as physisorption. The samples that exhibited a higher thermal stability were characterized to have a high surface area as well as low fluctuations in crystallite size, pore volume, and pore size. Ceria synthesized with cerium (III) nitrate hexahydrate and CTAB in a water:ethanol mixture using sodium hydroxide showed to be the most effective at providing a thermally stable product. Doping the catalyst with titanium increased the thermal stability significantly. Select samples were run in a variety of fuel to oxygen ratios to determine the best conditions in which we could perform partial methane oxidation to recuperate hydrogen gas. Most of the experiments show oxygen depletion with minor changes in other gas levels indicating that there is no oxidation occurring. Curiously the oxygen levels do decrease. There is a possibility that there is a reaction occurring initially at room temperature and being exacerbated with further temperature increase.

▼ An important question in research on metaphor comprehension is whether familiar and unfamiliar metaphors are understood through separate processes. In prior research, the Categorization model (Glucksberg, 2003) specifies that comprehension of familiar and unfamiliar metaphors relies on the same set of controlled processes, whereas the Career of Metaphor model (Bowdle & Gentner, 2005) specifies separate processes: a controlled process for unfamiliar metaphor comprehension and an automatic process for familiar metaphor comprehension. The present study assessed these competing models using a resource
depletion manipulation. Resource
depletion (Muraven & Baumeister, 2000) refers to the gradual
depletion of a limited executive or cognitive control resource during activities that draw upon this resource, eventually resulting in temporary performance impairments on any activity that requires the exertion of cognitive control. Because
depletion of the cognitive control resource negatively impacts higher-order controlled processes but does not affect automatic processes, the present study aimed to compare the effects of resource
depletion on comprehension of low- and high-familiarity metaphors to reveal whether automatic or controlled processes are recruited. In two experiments, resource
depletion was induced using a modified Stroop task, followed by a different metaphor-related task in each experiment. In this task, participants in both experiments were presented with the same set of short literal or metaphor (high, low, and mid-familiarity) sentences. In Experiment 1, participants were instructed to indicate when they had understood each sentence. In Experiment 2, participants were instructed to categorize the meaning of each sentence as “concrete” or “abstract”. Results for Experiment 1 indicated that resource
depletion slowed comprehension by much greater margins on mid- and low-familiarity metaphors compared to highly familiar metaphors. Results for Experiment 2 were inconclusive, as performance of the concrete/abstract categorization task was not sensitive to resource
depletion. Overall, the results support elements of both the Categorization and Career of Metaphor models, but support appears to be stronger for the Career of Metaphor model.

▼ Prostate cancer is one of the most common forms of
cancer in America affecting one in six men over the age of 65
(Greenlee et al., 2001). When confined to the prostate, surgical
removal of the prostate may be curative but when it spreads beyond
the prostate, treatment options include radiation, chemotherapy and
hormone ablation therapy. The tumor cells initially regress but
recur in a more aggressive and fatal form, which is resistant to
androgen ablation therapy.; Several pathways, including the MAP
kinase pathway have been implicated in the transition of prostate
cancer from an androgen-dependent (AD) state to an
androgen-
depletion-independent (ADI) state. In clinical samples
however, no mutations in the RASpathway components have been found
(Weber et al., 2004). Hence, we attempted to identify novel kinase
genes, which are potentially associated with
androgen-
depletion-independent (ADI) prostate cancer by screening a
library containing 354 activated human kinases. Based on this
screening we identified TPL2 as a novel kinase gene associated with
ADI prostate cancer, which was functionally validated by
gain-of-function and loss-of-function studies. ADI prostate cancer
growth of cells in culture was also seen to diminish in response to
a TPL2 kinase specific inhibitor. Finally, TPL2 is indeed
overexpressed in ADI prostate cancer in tumor samples and cell
lines derived from the PB-Cre/PTENf/f mouse model system, which
shows a prostate specific homozygous deletion of PTEN, leading to
prostate cancer development which is initially AD, but responds to
castration and recurs later in an ADI form.; Hence, we identified
TPL2 as a novel kinase gene associated with ADI prostate cancer,
which can serve as a potential therapeutic target against ADI
prostate cancer.

▼ Sustainability has become one of the most important issues for businesses, governments and society at large. Increasingly, it features in all planning for future activity. The topic is under much debate as to what it actually is and how it can be achieved, but it is completely certain that the resources of the planet are fixed in quantity, and once used, cannot be reused except through being reused in one form or another. This is particularly true of the mineral resources of the planet. These are finite in quantity, and once fully extracted, extra quantities are no longer available for future use. In this thesis, it is argued that the remaining mineral resources are diminishing significantly and heading towards extinction. Once mined and consumed, they are no longer available for future use other than what can be recycled and reused. What is becoming important therefore – both for the present and for future sustainability – is not the extraction of minerals, but their distribution. Future scarcity means that best use must be made of what exists, as sustainability depends upon this, and best use is defined in this thesis as utility rather than economic value, and this must be considered at a global level rather than a national level. This thesis investigates the alternative methods of achieving the global distribution of these mineral resources and proposes an optimum solution. It does so by showing the efficacy of Game theory for such strategic decision-making, and by developing the theory with some extensions pertinent to the environment being described, before performing the necessary mathematical manipulations to evaluate this environment, and then applying this to real world data. The findings are supported by using linear programming and sensitivity analysis, and by using real world data. Application of the results obtained would raise a number of problems with market regulations and with the geopolitical situation, and these also are explored at length. In achieving this research, the main contribution of this thesis is through identifying the new environment and the extending of Game theory into this environment and in developing the necessary extensions. Previous research has only proposed methods to deal with this, but never actually developed and tested any model; therefore, this model itself, is a contribution. An additional contribution has been made through the application of those extensions into the practical global arena, and in the consideration of the role of regulation in the management of the market for resources in a way which is effective globally rather than locally. Essentially, this is through an understanding of the dichotomy between competition and collaboration, where this thesis argues that the conventional economic mode does not work to best results. Therefore, this thesis adds to the discourse through the understanding of the importance of the depletion and finiteness of raw materials and their use for the present and the future, in order to achieve and maintain sustainability.

▼ Understanding and controlling the forces between colloidal particles in solution, along with the resulting stability of a dispersion of such particles, continues to be at topic of great interest. Although most laboratory studies focus on model systems in which the number of system species is kept to a minimum, real colloidal systems can be much more complex, consisting of multiple components that can vary greatly in size, charge, shape, etc. This dissertation focused on a topic that has received very little prior study, namely synergistic effects that can arise in mixed colloidal systems in which the resulting force and stability of the system cannot be predicted using results obtained in more idealized systems consisting of fewer components.
Two specific systems were studied. The first was a ternary system of particles in which micron-sized particles were in a dispersion containing both nanoparticles and submicron particles. It was shown through both computation modeling and direct force measurements that the nanoparticles can create attractive forces between the micron and submicron particles such that a halo of submicron particles is formed. This halo results in long range forces between the microparticles that cannot be predicted from measurements in systems containing only nanoparticles or only submicron particles. In addition, the forces can be large enough to alter the stability of a dispersion of these microparticles.
The second system consisted of microparticles in a solution containing nanoparticles and a polyelectrolyte, specifically poly(acrylic) acid. Again, through modeling and experimentation, it was found that complexation of the nanoparticles and polyelectrolyte molecules led to
depletion and structural forces between the microparticles that were substantially greater than the sum of the forces measured in systems of only nanoparticles or only polyelectrolyte. It was also found that these greater forces could lead to destabilization of a dispersion of microparticles that was stable when only nanoparticles or only polyelectrolyte was present.
While these results clearly demonstrate the difficulty associated with predicting forces and stability in mixed colloidal systems, they also indicate that such systems offer new and interesting opportunities for controlling stability that clearly warrant additional study.

▼ The present study develops the debate over whether self-control is a limited resource, by investigating the effects innate theories and perceived control have on self-control tasks following ego-
depletion. The present study followed previous research findings, one in particular (Job, Dweck & Walton 2010), to determine what the power in willpower could represent. Participants carried out a stimulus detection task consisting of a depleting condition and non-depleting condition. Following this a Stroop test measured self-control following
depletion, and a subsequent self-control task was included to control for individual differences and to test
depletion on a physical task. Questionnaires measuring participants innate theories about willpower (Job et al., 2010), locus of control (Duttweiler, 1984) and goal attainment control strategies (Wrosch, Scheier, Miller, Schulz, & Carver, 2003) were included in the study. The present study provides evidence for individual differences in innate theories and perceived self-control moderating ego-
depletion.

▼ Depletion calculations for nuclear reactors model the dynamic coupling between the material composition and neutron flux and help predict reactor performance and safety characteristics. In order to be trusted as reliable predictive tools and inputs to licensing and operational decisions, the simulations must include an accurate and holistic quantification of errors and uncertainties in its outputs. Uncertainty quantification is a formidable challenge in large, realistic reactor models because of the large number of unknowns and myriad sources of uncertainty and error.
We present a framework for performing efficient uncertainty quantification in
depletion problems using an adjoint approach, with emphasis on high-fidelity calculations using advanced massively parallel computing architectures. This approach calls for a solution to two systems of equations: (a) the forward, engineering system that models the reactor, and (b) the adjoint system, which is mathematically related to but different from the forward system. We use the solutions of these systems to produce sensitivity and error estimates at a cost that does not grow rapidly with the number of uncertain inputs. We present the framework in a general fashion and apply it to both the source-driven and k-eigenvalue forms of the
depletion equations. We describe the implementation and verification of solvers for the forward and ad- joint equations in the PDT code, and we test the algorithms on realistic reactor analysis problems. We demonstrate a new approach for reducing the memory and I/O demands on the host machine, which can be overwhelming for typical adjoint algorithms. Our conclusion is that adjoint
depletion calculations using full transport solutions are not only computationally tractable, they are the most attractive option for performing uncertainty quantification on high-fidelity reactor analysis problems.

▼ The current study was designed with the aim of increasing the understanding of
how concealing or disclosing a stigmatized sexual identity to a perceived accepting/non- accepting person affects ego
depletion. Ego
Depletion, (Baumeister, 1998) refers to the idea that certain tasks exhaust a limited pool of cognitive resources. Previous literature has explored how concealing a stigmatized identity is ego depleting; however, an examination of the relationship between ego
depletion and the concealment of the specific identity as a sexual minority has not yet been explored. LGBQ individuals are often faced with the challenge of navigating social situations to determine if they are comfortable disclosing their sexual orientation. The present study sought to address gaps in the literature on LGBQ coming out (concealing and disclosing sexual orientation), and more specifically, using an experimental design, this study explored how the exposure to accepting or non-accepting attitudes affected psychological functioning (ego
depletion) and anxiety. Participants (N = 144) completed an online survey during which they were presented with a scenario in which a fictional partner had an accepting versus non- accepting attitude. LGBQ participants chose to conceal or disclose their sexual identity, and then completed a measure of ego
depletion. Statistical analysis showed a statistically significant interaction between the Acceptance (positive-accepting attitudes versus negative-non-accepting attitudes) and Conceal/Disclose Group (Choice Disclose versus Choice Conceal versus Instructed Concealing). The results of this study have significant implications for the LGBQ community as a whole, and the profound clinical implications as well as potential areas of future research are discussed.

▼ Extreme weather and climate-related events can have pronounced environmental, economic and societal impacts, yet large natural variability within Earth’s constantly evolving climate system challenges the understanding of how these phenomena are changing. Increasingly powerful climate models have made it possible to study how certain factors, including anthropogenic forcings, have modified the likelihood and magnitude of extreme events.
This study examines climate observations, reanalysis fields and model output to assess how weather extremes and climate-related events have changed. Part 1 investigates the detection and attribution of surface climate changes in relation to ozone
depletion. Part 2 uses probabilistic event attribution and storyline frameworks to evaluate the role of anthropogenic forcings in altering the risk of extreme 1-day rainfall (RX1D) events for Christchurch, New Zealand in light of an unprecedented rainfall event that occurred in March 2014.
Extremely large simulations of possible weather generated by the
[email protected] Australia-New Zealand (
[email protected] ANZ) model found ozone forcings induced significant changes globally (< 3 hPa) in simulations of mean sea level pressure for 2013. A clear seasonal response was detected in the Southern Hemisphere (SH) circulation that was consistent with prior studies. Ozone-induced changes to average monthly rainfall were not significant in New Zealand with large natural variability and the limitation of one-year simulations challenging attribution to this climate forcing.
In Christchurch, model and observational data give evidence of human activity increasing the likelihood and magnitude (+17%) of RX1D events despite significant drying trends for mean total rainfall (-66%) in austral summer. For events similar to that observed during March 2014, the fraction of attributable risk (FAR) is estimated to be 27.4%. This result was robust across different spatial averaging areas though is sensitive to the rainfall threshold examined. Unique meteorological conditions in combination with anomalously high sea surface temperatures (SSTs) in the tropical South Pacific were likely important to the occurrence of this extreme event. These results demonstrate how human influence can be detected in present-day weather and climate events.

▼ Poly(A) binding proteins are a group of RNA binding proteins with specific affinities towards the poly(A) tract of eukaryotic mRNAs. Although the cellular function of PABP1 in mRNA metabolism is well characterized, the function of other cytoplasmic PABPs is less understood. The aim of this research was to elucidate the cellular function of PABP4. We observed a modest reduction in protein synthesis in PABP4 depleted cells. Additionally, we investigated protein-protein interactions, finding that PABP1 and PABP4 interact with one another. We also found that while PABP4 binds to Paip1, it failed to bind Paip2. Consistent with this observation, PABP1
depletion results in the degradation of Paip2. However, PABP4
depletion had no effect on Paip2 expression. Studies were also conducted to examine PABP1 and PABP4 expression during hypoxia and recovery. Our results did not show any detectable changes in cellular abundance of both PABP1, and PABP4 during hypoxia or recovery.

▼ Tumor cells have been reported to have two main energy checkpoints depending on the amount of available ATP. These checkpoints regulate the progression of tumor cells during the G1 phase and their progression from the G2/M phase. Thus, the cell cycle depends on the time needed to produce enough ATP to overcome the energy checkpoints. Although molecular mechanism of G1 energy checkpoint has been reported, G2 energy checkpoint has not been fully explained. Here, I have shown that ATP depletion at G2 phase blocks both mitotic entry and cyclin B nucleus translocation in multiple cell lines. In addition, G2-M transition was regulated by the level of intracellular ATP. ATP depletion maintains p-Cdk1 (Y15), which is widely known to be phosphorylated by Wee1 kinase. Moreover, ATP depletion at G2 phase induced p-Chk1 (S345). Thus, I treated Wee1 inhibitor, PD166285, during ATP depletion at G2 phase. PD166285 dramatically overcome G2 arrest by ATP depletion. In addition, I also treated DNA damage response signaling inhibitor to target Chk1. However, DDR signaling inhibitor did not overcome G2 arrest by ATP depletion. Experiment using chemical inhibition and siRNA for AMPK also revealed that ATP depletion-induced G2 arrest did not result from AMPK activation. Taken together, ATP depletion at G2 phase blocks mitotic entry through maintaining inhibitory phosphorylation of Cdk1. Moreover, I observed that some the G2 arrested cells treated with PD166285 eventually died, indicating potential therapeutic implication and Wee1 inhibition upon ATPdepleted cells.
진핵세포는 다양한 스트레스에 반응하여 세포주기를 조절하는checkpoint를 가지고 있다. 진핵세포의 세포주기에서 이용 가능한 ATP의 양에 따라 2 가지 주요 energy checkpoint를 갖는 것으로 보고되었다. 이 checkpoint는 G1 기 동안 종양 세포주기의 진행과 G2 / M transition의 진행을 조절한다. G1 energy checkpoint에서는 AMPK에 의해 cyclin E가 억제되는 molecular mechanism이 보고되었지만 G2 energy checkpoint는 아직 완전히설명되지 않았다. 본 저자는 G2 기에서 ATP 결핍이 세포주기에 어떤영향을 미치는지 알아보고자 하였다. ATP를 결핍 시키는데 사용한 약물은 glycolysis를 억제하는 2-DG와 mitochondrial Cytochrome C oxidase를 억제하는 NaN3를 사용하였다. Drugs를 처리하였을 때 ATP가 asynchronous 수준으로 떨어지는 것을 확인하였다. 그 다음 mitotic entry와 cyclin B nuclear translocation을 확인한 결과 mitotic entry와 cyclin B nuclear translocation이 차단된 것을 관찰할 수 있었다. 이러한 현상이 drugs을 wash out 해 주었을 때 정상수준으로 회복되는지 알아보고자 하였다. 그 결과 drugs를 wash out 했을 때 ATP와 mitotic index가 정상 수준으로 회복하였다. 그 다음 세포주기가 멈추는 현상이 정말로 ATP결핍에 의한 현상인지 알아보고자 또 다른 energy stress를 가해주었다. 2-DG와 mitochondrial complex I 을 억제하는 phenformin을 동시에 처리한 결과 세포주기가 정지되는 것을 확인하였다. 그 다음 glucose free media로 glucose starvation 시켰을 때에도 이러한 현상이 일어나는지 확인하였다. 그 결과 drugs 처리 때보다는 약한정도 였으나 어느정도 세포분열기로의 이행이 억제되는 것을 볼 수 있었다. 그 다음 세포내 ATP를 측정한 결과 2-DG와 phenformin을 처리하였을 때는 asynchronous 수준으로 떨어지는 것을 확인하였다. 하지만 glucose starvation 조건에서는 ATP가 조금 감소하는 정도였다. 따라서 세포내 ATP의 양에 따라 세포주기가 조절된다는 것을 알 수 있었다. 이러한 현상이 일어나는 기전으로 먼저 AMPK에 의한 것인지 알아보고자 하였다. siRNA와 inhibitor를 사용하여 AMPK를 억제하였지만 세포주기 진행억제가 극복되지 않았다. 따라서 G2 energy checkpoint에서 AMPK는 큰 영향을 미치지 않는다는 것을 확인하였다. 그 다음 DNA 손상에 의한 신호전달 경로를 확인한 결과 Chk1이 인산화 되는 것을 확인하였다. 다양한 inhibitor를 통해 Chk1의 인산화를 억제하였지만 세포주기 진행억제를 극복하지 못했다. 따라서 Chk1도 별다른 영향을 미치지 않는다는…

▼ Water availability for humans and the environment faces increasing threats from expanding populations and potential reduction in supply due to changes in climactic patterns. In light of these threats, the need to minimize stream
depletion, defined as the
depletion of flows in streams and rivers caused by groundwater pumping, becomes paramount. Stream
depletion associated with pumping wells has been quantified by both analytical and numerical approaches; however, methods for identifying the stream
depletion caused by new wells remain inefficient and require separate simulations for each potential well location. In this work, we develop adjoint equations of a coupled groundwater and surface water system that can be solved to calculate stream
depletion. We use MODFLOW with the stream package to solve the adjoint equations, and, unlike previous work, we allow the head and resulting flow in the river to change as a result of
depletion. With only one simulation of the adjoint equations, stream depletions can be calculated for a well at any location in the aquifer, making it an efficient method for siting future wells.

▼ This thesis is submitted as a PhD by Publication. Part A provides an overview of the thesis and summarises its context, research questions, methodological approach and key findings. Part B is a collection of nine, first-named academic papers. The thesis addresses two highly complex and controversial questions within energy policy, namely the nature and magnitude of ‘rebound effects’ from energy efficiency improvements and the extent and rate of depletion of global oil resources. Both of these questions are critically important to the development of a sustainable energy system and both are the subject of long-standing and highly polarised disputes. The thesis adapts, develops and applies a common methodology for reviewing the evidence on these questions, supplements this with original primary research and syntheses the results in a way that improves understanding and provides new insights. The thesis includes four papers examining different aspects of rebound effects and four examining different aspects of global oil depletion. Given the complexity of the chosen topics, the papers cover a wide range of questions, issues and approaches. Collectively the papers: clarify relevant definitional and conceptual issues; evaluate competing methodological and analytical techniques; appraise the methodological quality of empirical studies; identify levels of uncertainty and potential sources of bias; develop simple mathematical models; conduct statistical analyses of primary data; compare and evaluate the results of modelling studies; and synthesise results from multiple research areas to provide novel insights into poorly understood phenomena. A ninth paper evaluates the strengths and limitations of systematic review techniques when applied to complex, policy-relevant questions such as these. The thesis draws two main conclusions. First, rebound effects are frequently large and can substantially reduce the energy and carbon savings achieved from improved energy efficiency. Second, there is a significant risk that the global production of conventional oil will enter sustained decline before 2020. These conclusions run counter to conventional wisdom and have significant implications for public policy. The thesis also shows how the methodology of systematic reviews can be adapted and modified to make a valuable contribution to energy and climate policy research.

▼ Work is stressful as individuals may need to enhance, change, fake or suppress emotions through a process known as emotion regulation. One type of emotion regulation is surface acting in which individuals fake emotions to better align with organizational display rules. Surface acting has been found to contribute to emotional exhaustion, work-to-family conflict, feelings of inauthenticity and insomnia. Surface acting is common in customer jobs in which employees need to address customer concerns. Research has demonstrated that breaks can be used to help restore resources and reduce
depletion. Specifically, exercise has been found to be beneficial in helping employees combat the harmful effects of emotion regulation and the
depletion that comes with it. In this study, fifty participants completed a surface acting task in which they listened to audio-recorded negative restaurant reviews and were instructed to respond to the reviews without conveying negative emotions across a 90-minute in-lab experimental session. Participants were randomly assigned to one of four break conditions (no break, a passive break, an exercise break, or a flaw essay break) which occurred halfway through the experimental session. Participants then completed the surface acting task again for 20 minutes. The surface acting task was found to induce emotion regulation. Participants who received a break experienced a decrease in
depletion after the break, while participants who did not receive a break experienced an increase in
depletion. There was no evidence to suggest that exercise breaks were better at reducing
depletion than the other conditions. This thesis suggests that organizations should ensure that employees are receiving breaks during worktime to guarantee employees maintain high productivity.

▼ An inflammasome is a multi-protein complex that consists of a sensor protein, caspase-1, and often an adaptor protein ASC. An inflammasome assembles in response to microbial or danger signals and the assembly leads to autoproteolysis of pro-caspase-1 and, consequently, to processing of the inflammatory cytokines pro-IL-1β and pro-IL-18 and to a type of cell death called pyroptosis. NLRP1B is a cytosolic protein that forms an inflammasome in response to anthrax lethal toxin or reduction in cytosolic ATP levels. NLRP1B detects anthrax lethal toxin when the toxin cleaves an amino-terminal fragment from the protein. The mechanism by which NLRP1B senses reduction in cytosolic ATP is unknown. In chapter 3, I addressed whether the amino-terminal region of NLRP1B also serves as a sensor of reduced ATP levels. I found that an NLRP1B mutant lacking the amino- terminal region exhibited some spontaneous activity and failed to be further activated by lethal toxin, but was still activated by metabolic inhibitors, indicating that the amino-terminal region is not the sole sensing domain of NLRP1B. Comparison of NLRP1B alleles that differed in their response to metabolic inhibitors, but not to lethal toxin, led to the finding that a repeated sequence in the FIIND facilitated detection of ATP depletion. NLRP1B might sense ATP depletion as a way of sensing microbial infections. In chapter 4, I show that an infection with an intracellular pathogen, Listeria monocytogenes caused a reduction of cytosolic ATP levels and activation of the NLRP1B
inflammasome in a reconstituted system. NLRP1B activation was dependent on Listeriaâ s expression of a protein required for vacuolar escape, listeriolysin O. Furthermore, I show that infection with Listeria monocytogenes and Shigella flexneri also caused reduction of ATP and activation of NLRP1B in the murine RAW264.7 macrophage cell line.

▼ Testosterone is essential for regulation of spermatogenesis and testosterone withdrawal results in germ cell apoptosis. However, the mechanism for germ cell apoptosis is unknown. In testes, mature Leydig cells produce testosterone. Using ethane dimethane sulfonate (EDS), a Leydig cell-specific toxicant, to deplete testosterone, we investigated the relationship between granzyme and perforin, and germ cell apoptosis. To confirm effects of testosterone
depletion, EDS-treated rats were compared with testosterone-replaced and testosterone-supplemented rats. At 5 and 7 days post-EDS treatment, rats were euthanized for tissue collection. Leydig cell loss was confirmed by the significant reduction in mRNA for Lhr (90%) and Insl3 (99%), and testosterone
depletion was confirmed by the undetectable level of testosterone in serum and testes of EDS-treated rats. Due to ablation of testosterone, there was testicular weight loss (18%) along with a significant increase in germ cell apoptosis (135 cells/mm2 of testicular cross-section). However, no difference in testicular weight or numbers of apoptotic germ cells was observed in testosterone-replaced and testosterone-supplemented rats. Hence, although EDS eliminated Leydig cells, testosterone replacement maintained testicular weight and germ cell viability. In addition to increased germ cell apoptosis, the mRNA levels for grankyme K (GzmK) and perforin (Prf) were also significantly higher (2- and 2.5-fold, respectively) in EDS-treated rats compared to controls. After testosterone replacement, the levels of GzmK and Prf mRNAs were restored. The mRNA levels for Cd4 and Cd8 were also significantly elevated (2- and 5-fold, respectively) following EDS treatment, whereas testosterone replacement partially reversed it. Therefore, it was hypothesized that testosterone
depletion resulted in disruption of the blood-testis barrier allowing CD4+ and CD8+ T cells to migrate inside the seminiferous tubule. With recruitment of CD8+ T cells inside the seminiferous tubule, GzmK and Prf were released to induce germ cell apoptosis. However, CD8+ T cells were detected in the interstitium, whereas GZMK and PRF were detected inside the seminiferous tubule. This indicated that GZMK and PRF expression in testes may not be associated with CD8 + T cells. Moreover, detection of GZMK and PRF proximal to residual bodies indicated their possible role in germ cell release during spermiation.

▼ The resource depletion model of self-regulation proposes that people's ability to perform deliberate, effortful thought and behavior is a limited resource, with earlier self-regulation depleting this resource, leaving less for subsequent tasks. The current research investigated the pervasiveness of self-regulation depletion, explored various tasks as potential means of counteracting depletion, and assessed how mood was impacted by both. In a series of seven studies, participants completed an initial task that required either high or low levels of self-regulation and subsequent self-regulation measurement tasks, along with pre- and post-task measurements of mood. Some participants also completed various intervening tasks to assess the potential of different activities to counteract depletion. Our research indicated that self-regulation depletion, while common, is not inevitable when one has completed an earlier self-regulation task. We also found little evidence that completing the various intervening tasks such as exercise, magazine reading, and drawing, replenished participants' self-regulation resources. We did, however, find clear evidence that mood, both in terms of mood valence and arousal levels, is impacted by self-regulation, and some indication that these mood effects played a small mediating role in depletion.

▼ This study utilizes multiple aerosol datasets collected in Metro Manila, Philippines to investigate sea salt aerosol characteristics. This coastal megacity allows for an examination of the impacts of precipitation and mixing of different air masses on sea salt properties, including overall concentration and size-resolved composition, hygroscopicity, and morphology. Intensive size-resolved measurements with a Micro-Orifice Uniform Deposit Impactor (MOUDI) between July-December 2018 revealed the following major results: (i) sea salt levels exhibit wide variability during the wet season, driven primarily by precipitation; (ii) ssNa+ and Cl- peaked in concentration between 1.8 – 5.6 µm, with Cl-
depletion varying between 21.3 - 90.7%; (iii) mixing of marine and anthropogenic air masses yielded complex non-spherical shapes with species attached to the outer edges and Na+ uniformly distributed across particles unlike Cl-; (iv) there was significant contamination of sea salt aerosol by a variety of crustal and anthropogenic pollutants (Fe, Al, Ba, Mn, Pb, NO_3^-, V, Zn, NH_4^+); (v) categorization of samples in five different pollutant type categories (Background, Clean, Fire, Continental Pollution and Highest Rain) revealed significant differences in overall Cl-
depletion with enhanced
depletion in the submicrometer range versus the supermicrometer range; (vi) κ values ranged from 0.02 to 0.31 with a bimodal profile across all stages, with the highest value coincident with the highest sea salt volume fraction in the 3.2-5.6 µm stage, which is far lower than pure sea salt due to the significant influence of organics and black carbon. Analysis of longer term PM2.5 (particulate matter with aerodynamic diameter less than 2.5 µm) and PMcoarse (= PM10 – PM2.5) data between August 2005 and October 2007 confirmed findings from the MOUDI data that more Cl-
depletion occurred both in the wet season versus the dry season and on weekdays versus weekend days.
The effectiveness of three different pretreatment processes (Fluidized bed crystallization reactor, Ultrafiltration and ferric chloride coagulation and flocculation) in order to remove scale-forming and fouling substances from the wastewater secondary effluent were studied. At optimized conditions, fluidized bed crystallization reactor (FBCR) was able to remove >99.9% of magnesium, 97% of calcium and 42% of silica while ultrafiltration (UF) and ferric chloride coagulation were only able to remove 18% and 16% of the silica concentration, respectively. UF was also able to reduce the turbidity of the SE by 93%. Furthermore, the co-precipitation of different mineral salts with organic matter were also discussed using size exclusion chromatography-organic carbon detector (SEC-OCD). At optimized conditions, ferric chloride resulted in the highest natural organic matter (NOM) reduction (56%) compared to FBCR (26%) and UF (13%). Excitation emission matrix-parallel factor (EEM-PARAFAC) analysis were used to characterize the NOM in the SE and the effluent of these pretreatments. Five…

▼ A new utility has been developed with extensive capabilities in identifying nuclide decay and transmutation characteristics, allowing for accurate and efficient tracking of the change in isotopic concentrations in nuclear reactor fuel over time. This tool, named the Application Programming Interface for
Depletion Analysis (APIDA), employs both a matrix exponential method and a linear chain method to solve for the end-of-time-step nuclide concentrations for all isotopes relevant to nuclear reactors. The Chebyshev Rational Approximation Method (CRAM) was utilized to deal with the ill-conditioned matrices generated during the course of lattice
depletion calculations, and a complex linear chain solver was developed to handle isotopes reduced from the burnup matrix due to either radioactive stability or a sufficiently low neutron-induced reaction cross section. The entire tool is housed in a robust but simple application programming interface (API). The development of this API allows other codes, particularly numerical neutron transport solvers, to incorporate APIDA as the burnup solver in a lattice
depletion code in memory, without the need to write or read from the hard disk. Specifically, APIDA was developed for coupling with the coarse mesh radiation transport method (COMET) – a numerical transport solver extensively validated and shown to provide efficient and accurate whole core solutions to host of different reactor types. The APIDA code was benchmarked using numerous decay and transmutation chains. Burnup solutions produced by APIDA were shown to provide material concentrations comparable to the analytically solved Bateman equations - well below 0.01% relative error for even the most extreme cases using isotopes with vastly different decay constants. For further benchmarking, APIDA was coupled with the transport solver in the SERPENT code for a fuel pin cell
depletion problem. A sensitivity analysis was also conducted to determine the optimal number of isotopes to track for a typical pressurized water reactor (PWR) problem in order to accurately track the change in eigenvalue of the core. Results show APIDA to be effective and efficient in solving lattice
depletion problems, in addition to being successful in terms of portability for users to implement via the API.

▼ Charge-induced adsorption is a subject of significance to environmental and biological systems. Ice surface is believed to get charged with potassium deposition. Compared to uncharged ice film, the work function of charged ice film is significantly reduced due to the formation of metastable delocalized excess surface electrons donated by potassium atoms on ice. This charging effect is found to be dependent on temperature. It is also reported that adsorption of carbon tetrachloride would occur drastically on charged ice surface while almost no adsorption was observed on uncharged ice surface at low temperature. In addition, the results strongly agree with the cosmic-ray-driven electron-induced reaction (CRE) model for ozone depletion.

▼ Research evidence is suggestive of a strength model of self-control, also known as ego
depletion, in social psychological literature. Engaging in an initial task of self-control depletes a limited resource, resulting in less self-control on a subsequent, unrelated task. The strength model of self-control has been applied to many practical, everyday situations, such as eating behaviors among dieters. Newer studies suggest that blood glucose is the resource consumed during acts of self-control. Consuming glucose seems to "replete" individuals who have been depleted, improving performance and self-control. The current study aimed to examine the effects of ego-
depletion on restrained eaters. The hypothesis was that restrained eaters who were depleted by a task of self-control would exhibit more disinhibition on a taste-test task than would restrained eaters who were not depleted. However, if the participants were given glucose following the
depletion task, then their self-control would be "repleted" and they would exhibit similar control to that of the non-depleted participants. Contrary to expectations there were no differences between the groups in terms of total amount of cookies consumed. These results are inconsistent with a glucose model of self-control. Suggestions for future research and implications of the findings are discussed.
