▼ An extensive study of the performance of railroad superstructure in rail transit systems was conducted at the University of Illinois at Urbana-Champaign (UIUC) as part of a research program funded by the Federal Transit Administration (FTA). Focusing on field characterization of the performance of prestressed monoblock concrete crossties and premium elastic fastening systems, this project aimed to quantify the behavior of the aforementioned track superstructure elements under different rail transit loading conditions. Instrumentation was deployed at three different North American rail transit agencies; on a light rail transit system, on a heavy rail transit system and on a shared corridor with both commuter rail and freight train traffic, targeting specific aspects for each of the track components included in the study. Extensive field monitoring spanned over several months for all the sites and large data sets were developed. Flexural performance results of crossties under light rail loading conditions were compared with projected design capacities obtained from the application of current design standards, and a structural reliability analysis (SRA) was employed to study the flexural capacity of the sleeper design, calculating the probability of failures. Furthermore, results from an extensive field study of temperature effects on the flexural behavior of rail transit concrete crossties is presented. The temperature study comprised the analysis of the relationship between temperature in the crosstie and the ambient temperature, the effect of curling due to temperature gradient on the flexural performance of concrete crossties, and the potential additional stresses due to nonlinear temperature gradient, shedding additional light on their effect on the design of prestressed monoblock concrete crossties. To complete the railroad superstructure analysis, rail displacements of different fastening system designs and under varied loading scenarios were analyzed and compared. This thesis aimed to provide additional insight into the design of railroad track components for rail transit applications. Current design methodologies used in the rail transit industry do not always lead to accurate, optimal designs. To aid in closing this gap and improving the efficiency of designs, this thesis proposes a probabilistic-based design approach, quantifies the effect of temperature on concrete crosstie flexural behavior, and presents the advantages of using field instrumentation to analyze the behavior of railroad track components.

▼ The growth of individuals is one of the most studied life history traits in ecology, because information on growth rates provides an integrated measure of an individual’s health, stress, food availability, reproductive potential, social hierarchy, and ability to avoid predation. These individual-level processes contribute substantially to our understanding of population-level dynamics which, in fisheries science, is used to inform conservation and management decisions, such as stock assessment models and harvest regulations. Fish growth, in particular, is heavily influenced by a multitude of abiotic and biotic factors, of which water temperature is the primary driver. This is because water temperature regulates the metabolic rate of fishes and therefore the amount of energy that must be allocated towards basal maintenance instead of fitness-related activities such as growth. Climate change has caused water temperatures to rise globally and is projected to continue to rise in the future. The consequences of changing water temperatures will vary spatially and by species – benefitting the growth of some species, while hindering the growth of others. Therefore, studies aimed at quantifying macroscale water temperature effects on fish growth are necessary in order to understand and predict a species’ response to a warming climate. The purpose of my thesis is to improve our understanding of how macroscale changes in water temperatures may impact the growth of fishes. Specifically, I provided a quantitative framework that can be used to help design studies for detecting macroscale effects on growth, as well as, provided insights into how the growth of a cool-water species may be influenced by warming water temperatures. In chapter one, I created a novel quantitative framework to assess the ability to detect a macroscale effect (e.g., largescale water temperature effect) on fish growth. To date, there is no statistical framework for assessing the ability to detect macroscale effects on fish growth. Designing these types of studies can be difficult, due to the hierarchical nature of the data, where samples of fish are nested within the sample of lakes across the landscape and the large amounts of variability in length-at-age data. The framework was developed to address these design challenges by identifying the sample size needed to detect an effect of a given magnitude, as well as, diagnosing what effect sizes are detectable given the amount of among-fish and among-lake variability in a system of interest. All R code used to run the framework is made accessible to researchers so that it may be adapted to meet various research and management goals, including investigating additional macroscale effects, applied to different species, and sampling scenarios. I illustrated this framework by assessing the ability to detect a macroscale water temperature effect on the growth of flathead catfish (Pylodictis olivaris) and yellow perch (Perca flavescens) across a range of sampling scenarios. These scenarios varied in the number of… Advisors/Committee Members: Tyler Wagner, Thesis Advisor/Co-Advisor, Duane Diefenbach, Committee Member, C.

▼ One means of evaluating the temperature requirements of an animal is to determine changes temperature causes in the uses and losses of energy and materials in the food the animal consumes. To develop energy budgets for cichlids (Cichlasoma bimaculatum) at different temperatures (20, 24, 28, 32 and 36 C) data were obtained on food intake, growth (total, fat, and protein), fecal losses, maintenance requirements, and other uses and losses of energy and materials including specific dynamic action, activity, and nitrogen excretion. Starvation experiments were conducted to provide information on the metabolic cost of existence and on adjustments in body composition in the absence of food. Energy expenditure during starvation, estimated from heat of combustion data, was found to increase linearly with temperature over 4, 13 and 20 days of starvation. The caloric cost of existence per fish per day was greatest during the first four days at all temperatures and decreased as starvation was prolonged to 20 days. Caloric losses, and dry weight losses showed essentially the same thing. Protein catabolism increased regularly with temperature and decreased slightly with duration of starvation. Fat catabolism did not vary significantly with temperature but decreased markedly as starvation was prolonged. Food intake, growth, and food conversion efficiency varied greatly with changes in temperature. Cichlids were fed ad libitum on small aquatic worms of the genus Tubifex. For food consumption as well as growth, the optimum temperature dropped from 32 to 28 to 24 C as the experimental period was extended from 5 to 12 to 19 days. Optimum growth in dry weight and calories occurred at the same temperatures. Growth of cichlids through time at 20 and 28 C was nearly linear; at 24 C the curve was exponential. At 32 and 36 C, the growth curves rose and then declined. When the fish were held separately during the experiment, food conversion efficiency of cichlids was highest at 20 C and decreased with increasing temperature. Efficiencies decreased with duration of the experiment. When fish were held in groups during the experiment, efficiency was low at both high and low temperatures. The guts of the cichlids were found to contain food up to 30 hours after an ad libitum meal at all temperatures. They were reasonably empty after 36 hours. Thus, no significant correlation was found between temperature and the length of time necessary for the guts to empty. Food material not absorbed was measured by wet combustion. Percentages of absorption of unrestricted rations were found to be 83, 84, 88, 85 and 69 at 20, 24, 28, 32 and 36 C. Percentages of food absorption were much higher on the restricted ration than on the unrestricted ration. Absorption appears to have been optimal at 28 C. Specific dynamic action (SDA) was estimated at different temperatures by taking the difference between oxygen consumption of unfed and fed cichlids at the same levels of activity. SDA represented 22, 20, 19, 33 and 33… Advisors/Committee Members: Warren, Charles E. (advisor).

▼ The relationship of temperature and salinity to protein synthesis was determined for cells of Vibrio marinus, MP-1. Protein synthesis was measured by the incorporation of radioactive proline into hot trichloroacetic acid precipitable material. At all salinities protein synthesis occurred at 15°C and 20°C but not at 25°C. The critical temperature of the lesion in protein synthesis increased with increasing salinity of the growth medium. A significant inhibition of protein synthesis occurred at 22°C at a salinity of 25%₀, but no inhibition of protein synthesis occurred at a salinity of 35%₀ until the cells were incubated for 20 minutes at 24°C. The possibility that the thermal lesion involved precursor accumulation mechanisms rather than protein synthesis at salinities between 25%₀ and 35%₀ was eliminated by determining the uptake of labeled proline by whole cells. At 40%₀, the uptake of extracellular amino acids was inhibited at 24°C and preceeded the inhibition of precursor into protein. RNA synthesis studies were determined at incubation temperatures inhibitory to protein synthesis. RNA synthesis was measured by the incorporation of radioactive uracil into cold trichloroacetic acid precipitable material. Total RNA synthesis continued for 50 minutes at 22°C in growth media at salinities between 15%₀ and 35%₀. At a salinity of 40%₀, incorporation of uracil into RNA decreased after 20 minutes of cell incubation at 22°C. At growth medium salinities between 15%₀ and 30%₀, total RNA synthesis continued at 15°C and 22°C, but cellular protein synthesis was inhibited by either temperature or salinity effects. Studies of cell viability loss at 22°C and 25°C in growth media at salinities of 25%₀ and 35%₀ showed that the onset of cell death occurs simultaneously with thermal inhibition of protein synthesis. The death of cells occurs more rapidly as the salinity of the growth medium is lowered and as the temperature of cell incubation is increased. Advisors/Committee Members: Morita, Richard Y.

▼ Soot particles are harmful emissions that can effect human health, the environment and contribute to global warming that is why the study of soot formation is crucial. A better understanding of soot formation can lead to more efficient combustion device designs, reduce their emissions and their impact on human health and the environment. This thesis contains two different detailed numerical studies. This work aims to find solutions to reduce soot by controlling combustion variables (Chapter 3) and understand the current ability of chemical mechanisms to predict PAH and soot concentrations (Chapter 4) by applying a detailed numerical method. The results of the numerical studies are obtained using the CoFlame code. This detailed code models the formation of soot particles in a laminar coflow C2H4/air diffusion flame by applying a fixed sectional method and accounting for processes such as reversible nucleation and condensation, soot surface growth and oxidation. The first objective is to model and investigate the effect of inlet coflow temperature on soot formation. Inlet coflow temperature plays an important role in soot formation as it can effect the reaction rates and fundamentals of soot formation process such as surface growth, nucleation and condensation. Previous studies of soot formation using the CoFlame code have focused on the modeling of the effect of pressure, diluents, and fuel types on soot formation; however, the effect of coflow temperature at lower temperatures has not been previously studied using this detailed numerical approach. The results suggest that the soot volume fraction increases in flames with a higher inlet coflow temperature. This phenomenon is associated with the high inception rates at the lower flame region and increase in the number of primary particles which will increase the possibility of more surface reaction. The second study shows the difference of two important kinetic chemical mechanisms, the chemical mechanism developed at the German Aerospace Center, referred to as the DLR mechanism, and the mechanism developed at the King Abdullah University of Science and Technology, referred to as the KAUST mechanism. The effect of these mechanisms on soot aerosol dynamics and, therefore, the formation of soot particles is studied. The results of this study suggest that there is still a need to develop a chemical mechanism which can accurately predict both the species concentration and soot volume fraction.

▼ As a study organism, annual killifish (Austrofundulus limnaeus) provide a well suited study system for examining the effects of environmental temperature fluctuations at the cellular level. A. limnaeus persist in the harsh high desert climate of the Maracaibo Basin, Venezuela where they live in small, ephemeral freshwater pools. Temperatures in these waters can vary as much as 20 degrees C daily and reach maximums of over 40 degrees C due to the semi-arid climate. Previous cDNA microarray studies on killifish revealed the mRNA pattern for High Mobility Group Protein 1 (HMGB1) to be strongly affected by temperature perturbations. Specifically, peaks in hmgb1 transcript abundance were negatively correlated with temperature during temperature cycling, and experienced over a 10 fold difference in expression in response to the temperature cycle. Using the same temperature cycling experimental setup, this study's aim was three-fold: (1) to characterize the total amount of HMGB1 protein in adult male killifish livers, (2) to describe the subcellular localization of the HMGB1 protein in adult male killifish livers and (3) to sequence the 5' upstream region of the hmgb1 gene to identify possible stress responsive elements. We detected no significant difference in total HMGB1 protein levels as a consequence of temperature cycling. The data for subcellular localization of HGMB1 protein do not support a strong change in subcellular localization of the protein in response to temperature cycling; most of the HMGB1 protein is found in the cytoplasmic compartment in liver tissue. Although overall patterns of subcellular localization did not change significantly, we found a significant difference between nuclear HMGB1 protein levels in temperature cycled fish versus control (constant temperature) fish. This could suggest a muting of the natural translocation of HMGB1 into the nucleus observed in control fish at around 9:00 at night. Finally, the upstream region of the hgmb1 gene does reveal a number of putative stress responsive transcription factor binding sites. Advisors/Committee Members: Jason Podrabsky.

▼ Accurate predictions of algal productivity during outdoor cultivation are critically needed to assess the economic feasibility and the environmental impacts of full-scale algal cultivation. The literature shows that current estimations of full-scale productivities are mainly based on experimental data obtained during lab-scale experiments conducted under conditions poorly representative of outdoor conditions. In particular, the effect of temperature variations on algal productivity is often neglected. The main objective of this thesis was to develop a model able to predict algal productivity under the dynamic conditions of temperature and light representative of full-scale cultivation. In a first step, models were developed to predict broth temperature as a function of climatic, operational, and design parameters. The model developed for open ponds could predict temperature at an accuracy of ±2.6 °C when assessed against experimental data collected in New Zealand over one year. The temperature model developed for closed photobioreactors was accurate at ±4.3 °C when compared to experimental data collected in Singapore and New Zealand over a total of 6 months of cultivation. This second temperature model was then applied at different climatic locations to demonstrate that actively controlling temperature would seriously threaten the economics and sustainability of full-scale cultivation in photobioreactors. To quantify the impact of temperature variations on biomass productivity, a productivity model was developed using Chlorella vulgaris as a representative commercial species. To determine the best methodology, a review of more than 40 models described in the literature revealed that an approach accounting for light gradients combined with an empirical function of temperature for photosynthesis and first-order kinetics for respiration would offer the most pragmatic compromise between accuracy and complexity. The model was parameterized using short-term indoor experiments and subsequently validated using independent benchscale indoor (> 160 days) and pilot-scale outdoor (> 140 days) experiments, showing prediction accuracies of ± 13%. The outdoor data set was obtained from 13 different experiments performed in 4 different reactors operated under various regimes and climatic conditions. The productivity model was found to be accurate enough to significantly refine previous assessments of the economics and the environmental impacts of full-scale algal cultivation. The productivity model was then used in different case studies in order to investigate the impact of location/climate, design (pond depth or reactor diameter), and operation (hydraulic retention time or HRT) on productivity and water demand. Although the qualitative impact of the HRT on process was already known, this application enabled the first quantification of the HRT value on the productivity. Low HRT values around 3 days were found to maximize productivity at most locations investigated but these operating conditions were…

▼ Dengue fever is a mosquito-transmitted disease that is endemic in many parts of the tropical world and affects a significant proportion of the human population. Temperature is known to influence aspects of the dengue transmission cycle, which has consequences for disease dynamics. Previous work has explored the effects of temperature on the mortality rate of the mosquito and the resulting population change. However, there is substantial evidence that the extrinsic incubation period (EIP) of the pathogen within the vector host, Aedes aegypti, is also temperature dependent. This dependence has not been thoroughly researched. We present a single serotype compartmental model with a gamma-distributed exposed vector class to account for a temperature-dependent EIP. Where appropriate, temperature-dependent vector mortality is convolved with the temperature dependent EIP using the mortality function presented by Yang et al. [49]. Both seasonal and diurnal temperature changes are examined for their potential effects upon dengue persistence. The mean and range of temperature fluctuations that facilitate persistence are presented based upon the EIP function, initial conditions, seasonal temperature forcing with and without vector mortality, as well as seasonal and diurnal temperature forcing with and without vector mortality. With seasonal forcing and temperature dependence only in the EIP, all simulations with mean temperatures above 26 C show persistence. However, if vector mortality is also variable, persistence is no longer possible in higher temperatures with higher temperature ranges. Diurnal forcing exacerbates this effect limiting persistence to mean temperatures of 23 C to 34 C with variable temperature ranges. It is clear that more data are needed to reduce the uncertainty in estimating the relationships between both EIP and vector mortality because these relationships can have large effects on disease dynamics. Additionally, this work demonstrates that when modeling temperature-dependent effects, it is vital to not only include seasonal variation in temperature but also diurnal variation.

▼ ABSTRACTNon-contacting displacement/distance sensors are widely used for position measurement to ensure the performance of the system, especially when the target surface is hard for sensor setup. Inductive planar displacement sensors are widely used to measure the position of the object in terms of measuring the equivalent inductance of the sensing planar coil. Compared to other types of non-contacting displacement sensors, including optical, microwave and capacitive sensors, inductive displacement sensors are less sensitive to environmental factors, easy installing in narrow space, robust, and low cost.Nevertheless, the output of the inductive planar coil (i.e., the equivalent inductance) can be affected by the material and the shape of the target, high-temperature and the tilt angle of the object. I used FEA method to simulate the eddy current on the targets and the equivalent inductance of the sensing coil with different materials, shapes, environment temperatures and target tilt angles. First, the eddy current distribution on various targets of different materials and shapes was analyzed to prove the hypothesis that the eddy current distribution on the target can be modeled as a ring-shaped virtual coil. Thus the coil-to-target interaction model can be simplified as a coil-to-coil interaction model, which was the basis for a calibration simplification method for targets made of different materials, developed by our research group. The simplified calibration process based on the validated coil-to-coil model was confirmed using FEA results. Second, high-temperature effects, including the thermal expansion and material properties change, were studied to figure out the high-temperature influence on the equivalent inductance change. It was found that material conductivity change is the dominating factor on the equivalent inductance of the sensing coil under high temperatures. Therefore the high temperature can be simplified as changing target material, so that the simplified calibration method to targets made of different materials can be used for targets at varying temperatures. Finally, the target tilting effect on the equivalent coil inductance was studied; a method was proposed, which can be used for both tilt angle and displacement measurement using a single planar coil.In summary, in my thesis, I proved a hypothesis that the eddy current distribution on the target can be modeled as a ring-shaped virtual coil regardless of the target shapes and materials. With this hypothesis, I further confirmed a calibration simplification method developed by our research group. I also found that at varying temperatures, the target material property change is the dominant factor such that the calibration method can still be used. Such findings can be used in blade tip measurement for gas turbine machines. I also simulated the tilting effect, from which a method was proposed to measure both the tilt angle and the distance from the target using a single planar coil. The results can benefit the target displacement measurement when… Advisors/Committee Members: Zhe, Jiang (Advisor).

▼ With the rapid development of science and technology, Low temperature poly-silicon thin film transistor (LTPS TFTs) play an important role in small and medium-sized panels. The biggest difference between LTPS TFTs and Amorphous- silicon TFTs display is that LTPS speed of operation is faster and better. Besides, LTPS have high luminance, high resolution, low power consumption and lightweight and short. Therefore, LTPS will be the mainstream of small-size wearable display in the future. It pointed out that reliability has been the research emphases of Low-temperature poly-silicon thin film transistor. Under high bias, high current and light illumination operation can cause electrical characteristic degradation. Especially, hot-carrier effects and self-heating effects. These are important issues in practical TFTs operation. In this paper, we studies hot-carrier effects and self-carrier effect in p-type flexible LTPS TFTs. Using different measurement, changing sizes of devices and different frequency of operation. Finding out the deterioration caused by different operating environments, and to further analyze and bring up solutions. In the first part, the abnormal electrical characteristics after Hot-carrier Stress in p-type flexible LTPS TFTs is investigated. It was found out the electrical characteristics changes mainly caused by Hot-carrier induced electron trapping in small channel width. The channel of device become shorter is due to electron trapping in oxide layer, and on current rising let C-V transfer earlier. In addition, OFF current decrease can verify the changing characteristics of the device is due to hot-carrier stress induce electron trapping. In second part is going to investigate self-heating effect cause characteristics changing in device. The self-heating effect is affected by the size of the channel width. After stress, the negative threshold voltage shift and OFF current decreases mainly caused by Self-heating effect and Hot-carrier effect. As the channel width getting lager, the condition of heat dissipation is poor and the distance from border gets further which make the degradation more obviously. Due to the high current operation, the channel will induce Joule heating and electric field during self-heating stress is strong near the source, and the NBTI is induced that descend the thickness of buffer layer which can abstract the heat effectively. By discussing the condition of Self-heating effect at different substrate further, we found out that the heat conductivity of PI is lower than the Glass. Therefore, the deterioration of PI with Self-heating effect is bigger than Glass. Advisors/Committee Members: Ting-Chang Chang (committee member), Tsung-Ming Tsai (chair), Ann-Kuo Chu (chair).

▼ The ability of a symbiotic organism to tolerate and respond to stress is dependent on a complex integration of the physiological processes of both host and symbiont. In the intertidal zone, where organisms are exposed to numerous environmental stressors, physiological tolerance limits of algae and animals are often within 1°C - 3°C of the body temperatures they experience there. To understand the association between intertidal sea anemones and their photosymbionts, and how these associations may change with increasing climatic stress, I examined two spatially dominant species in the genus Anthopleura (A. elegantissima and A. xanthogrammica) in symbiotic associations with their relatively sensitive chlorophyte photosymbiont, Elliptochloris marina. Anemones hosting E. marina were exposed to an increasing thermal regime from 10 - 28°C, under two light treatments, over the course of 10 weeks to establish the upper thermal tolerance limit of E. marina in each host, while examining the response of the anemones themselves to the thermal stress. Of the two hosts, A. xanthogrammica was less tolerant of high temperatures. A contraction response was triggered for A. xanthogrammica at temperatures above 18°C, but A. elegantissima showed no contraction until temperatures reached 24°C. To determine how the E. marina were responding to the temperature increases, I examined the photochemical efficiency of PS II by measuring photosynthetic efficiency (Fv/Fm) and photosynthetic capacity (rETRmax) of symbionts within each anemone host at each temperature interval. Photochemical efficiency was strongly affected by temperature; however, there were no apparent host-specific differences. From 10 - 22°C, Fv/Fm remained stable, averaging 0.6 ± 0.1 (SD) for both species. At temperatures above 22°C, photochemical efficiency steadily declined, indicating photoinhibition and the upper thermal tolerance limit of E. marina. This relatively low thermal tolerance may influence the competitive balance of symbionts under conditions of increasing global temperatures. Increasing temperatures may cause anemones to adaptively expel symbionts to switch to a more tolerant species. In this study, both A. elegantissima and A. xanthogrammica expelled symbionts as the temperatures rose. By 28°C, both Anthopleura species had expelled the majority of their symbionts; however, A. xanthogrammica was able to retain a higher percentage (A. elegantissima: 96.7 ± 4.6 % loss; A. xanthogrammica: 84.0 ± 18.1 % loss), indicating that they may have an increased ability to buffer temperature changes and maintain algal symbioses during prolonged periods of high temperatures. Field measurements of the internal body temperatures of A. xanthogrammica indicated that the anemone has a moderate ability to buffer its symbionts from thermal stress, as the internal body temperatures of lower intertidal anemones remained 6.2 ± 1.1°C cooler than ambient temperatures. This ability to moderate the internal temperature is likely due to host-specific morphological traits, such as a large… Advisors/Committee Members: Bingham, Brian L., 1960-, Matthews, Robin A., 1952-, Donovan, Deborah Anne, 1964-.

▼ Invasive plant species are becoming a major concern because they have been found to have negative effects such as decreasing biodiversity and inhibiting growth of native species. Microstegium vimineum, also known as Japanese stiltgrass, is such an invasive species. Because M. vimineum has spread quickly to many variable environments in the United States and because it is also an annual plant species, it is possible that this invasive grass has undergone contemporary evolution. I hypothesized that M. vimineum is undergoing contemporary evolution via local adaptation. With growth chamber and field experiments, I specifically tested the hypothesis that highaltitude populations have adapted to their cool environments by having higher germination, seed number, and reproductive effort at cool temperatures, and that the opposite is true for low-altitude populations. I also tested two hypotheses regarding the selective advantage of cleistogamy, the resource allocation hypothesis and the optimal genotype hypothesis. To test the hypothesis, I measured germination, flower phenology, total seed number, chasmogamous and cleistogamous seed number, percent cleistogamous/total seed number, and reproductive effort of plants from populations sampled along an altitudinal gradient. Plants were grown outside and in two growth chambers set at two temperatures. For the growth chamber experiment, I found that altitude affected germination, total seed number, and percent cleistogamous seeds. Temperature also affected germination, total seeds, cleistogamous seed number, and percent cleistogamous seeds. Low-altitude populations had higher germination and seed number in warm temperatures and high-altitude populations had higher germination and seed number in cool temperatures. There was an altitude by temperature interaction for total seeds, number cleistogamous seeds, and percent cleistogamous seeds. For the field experiment, altitude had an effect on germination, number of chasmogamous seeds, and reproductive effort per plant. As altitude increased, germination and number of chasmogamous seeds decreased, and reproductive effort increased. My results are consistent with the hypotheses that M. vimineum shows phenotypic variation associated with altitude and temperature and has undergone contemporary evolution in North Carolina.; Invasive plant species, Microstegium vimineum, Japanese stiltgrass Advisors/Committee Members: Elizabeth Lacey (advisor).

▼ ENGLISH ABSTRACT: Apple trees, that do not fulfil their winter chill requirement, undergo inadequate dormancy release resulting in poor budbreak with irregular and delayed flowering that impact negatively on fruit production and tree architecture. Under mild winter conditions, such as most production sites in the Western Cape region of South Africa, the application of chemical rest breaking agents is standard practise to artificially release dormancy and synchronise budbreak in spring to ensure sustainable and profitable apple production. However, rest breaking chemicals can be harmful to the buds and may result in phytotoxic damage if not applied optimally, therefore a good understanding of the dormancy status of the buds is valuable and necessary to mitigate this risk when applying a rest breaking agent. Furthermore, little information is available on the physiological and biochemical dynamics of commercially produced apple buds when under these milder conditions and no information is known for the ‘Cripps Pink’ variety when grown under climatically contrasting South African conditions. The main aim of this study was to investigate the effect of inadequate winter chill and the application of a blend of hydrogen cyanamide and mineral oil (HCo) as a rest breaking agent on the respiration rate and lipid composition of the terminal buds of full bearing ‘Cripps Pink’ apple trees. Dormant apple buds from two climatic regions, Elgin (insufficient winter chill) and the Koue Bokkeveld (sufficient winter chill) were compared in terms of their respiration rate and lipid composition. Buds from the Elgin region were also tested and compared after receiving a commercial HCo treatment at budswell. Shoots were excised and given a specified amount of artificial chill in the laboratory to act as a point of reference. Apple buds exposed to sufficient chill (orchard and laboratory) showed an early dormancy entrance, high maximum dormancy level and an early release, while buds from the milder area generally showed atypical dormancy behaviour. During winter, the total respiration rate and the rate of the main respiratory pathways (tricarboxylic acid cycle (TCA) and cytochrome C (CYT)) were reduced with the decline in temperature. Their levels increased again in the cold area at the beginning of spring to provide energy for growth resumption. In contrast, the main respiration levels remained low in the warm area and the pentose phosphate pathway (PPP) and alternative pathway (ALT) tested higher suggesting an attempt by the plant to compensate for the deficiency in energy production. The HCo treatment induced hypoxia in the buds and immediately decreased the total respiration as well as the main respiratory pathways (TCA and CYT). After this initial response the treated buds showed a significant increase in respiration and reached high levels towards budbreak and green-tip stage. This increase was not observed in the untreated buds from the mild winter climate, in contrast, these buds maintained a higher use of the PPP … Advisors/Committee Members: Louw, Esme Denise, Steyn, Wiehann J., Stellenbosch University.

▼ Anthopleura elegantissima, the common Pacific sea anemone, can host two very different algal endosymbionts: zooxanthellae (Symbiodinium muscatinei) and zoochlorellae (Elliptochloris marina). The photosynthetic carbon provided by the symbionts supplements the host's heterotrophic feeding, with zooxanthellae potentially translocating five times more carbon to the host than do zoochlorellae. We developed a method to measure lipid levels of zooxanthellate and zoochlorellate A. elegantissima in different seasons, focusing on non-polar lipids that are important components of gonad and gametes. In July 2009 and January 2010, zooxanthellate and zoochlorellate A. elegantissima were collected from the same habitat at the same tidal height. Non-polar lipids were extracted and separated into classes by thin layer chromatography. A semi-quantitative analysis of the chromatography plates allowed a determination of how lipid identity and quantity varied seasonally and by the symbiotic state of the anemone. Anemones collected in July were, on average, 41% larger than those collected in January. Total non-polar lipid content showed no significant seasonal pattern, but cholesterol and palmitic acid (a fatty acid) were present in greater proportions in all January anemones. Zooxanthellate anemones had significantly more non-polar lipid than zoochlorellate anemones in both seasons, and a significantly greater percentage of their lipid was composed of cholesterol and palmitic acid. The winter decrease in body mass likely resulted from increased rates of fission, metabolism of stored lipids, a decrease in food availability, and seasonally reduced translocation of photosynthetic products from the symbionts to their hosts. The reduction in symbiont-derived products may impact the ability of the host anemone to direct resources to development of gonad tissues. Zoochlorellae, which translocate less carbon to their hosts under most conditions, also appear to translocate different products. These differences would be magnified if A. elegantissima switch from zoochlorellate to zooxanthellate under the conditions of increasing temperature predicted in global climate change scenarios. Whether these changes ultimately increase or decrease fitness and whether such changes will also be seen in other symbiotic cnidarians (e.g., corals), that switch symbionts under environmental stress, are important questions that deserve additional attention.

▼ In the last decade,various structural designs and sensing mechanisms of ion sensors have been widely used in industrial,environmental monitoring and biomedical areas.However,the sensing characteristics of those ion sensors are obviously affected by the temperature of testing solution and therefore results in wrong readouts.To improve this issue,this thesis devoted to develop an extended-gate field-effect transistor(EGFET) based micro ion sensors with temperature compensation and calibration functions.The output characteristics of the presented EGFET ion sensors are measured under different temperatures (20â~50â) and various hydrogen ion concentrations (pH2~pH10). This thesis utilizes micro-electromechanical systems (MEMS) technology to develop EGFET-based micro ion sensors.The signal readout circuit is built by four components:bridge readout circuit,temperature sensors,temperature calibration circuit and differential temperature compensation circuit.The EGFET-based micro ion sensor and the signal readout circuit are combined to form the EGFET-based ion sensor with temperature compensation and calibration functions.The main processing steps of the EGFET in this study involue four photolithographic and two thin-film deposition processes.The influence of output characteristics before and after the temperature compensation,and the temperature range of compensation could be obtain in this study. The chip size of the EGFET microsensor is 11 mm Ã 13 mm Ã 0.5 mm and the sensing area is 1 mm Ã 1 mm.The temperature range of the measured standard buffer solution is from 20â to 50â,and the various hydrogen of the standard buffer solution is from pH2 to pH10.The measured results show that the temperature compensation circuit has excellent compensation effect under 20â~45â, respectively,without temperature compensation.After temperature compensation,the average error the various hydrogen have become 12.71% and 15.43% under 20â and 45â,respectively,without temperature compensation.After temperature compensation, the average error of the various hydrogen have become 8.16% and 11.38% under 20â and 45â,respectively.The temperature compensation and calibration circuit in this study has significantly reduce the error of the signal readout characteristic.

▼ Towards development of a mechanical model that can be part of multi-physical analysis of frozen soils, a program of systematic frozen-unfrozen parallel triaxial tests at different temperatures and strain rates was conducted. The mechanical behavior of the reconstituted high-plasticity clay samples was investigated and interpreted through state concept based on Ladanyi and Morel’s (1990) postulate on the unique relationship between the inter-particle “effective” stress and the strain path.To begin with, constant-condition (i.e., constant strain rate and temperature) compression tests were conducted on frozen Kasaoka clay specimens with normal consolidation prior to freezing. With other conditions set identical, the shear strength linearly increased with a decrease in temperature for the range from -10 °C to -2 °C, and log-linearly increased with an increase in the strain rate for the range from 0.001%/min to 0.1%/min. Direct comparison of the strain-rate effects between frozen and unfrozen specimens with identical strain paths and states in the soil skeleton clearly indicates that the viscoplasticity derives from that of pore ice. The Critical State lines (CSLs) for clay specimens frozen undrained were mapped by referring to the shear behavior of unfrozen specimens sharing the same strain history. Moreover, reduction of confining pressure after stabilized freezing of frozen specimens turned out to have no significant effect on critical state strength of frozen clay.By varying-temperature and varying-strain rate compression tests, consistency of stress-strain curves was observed at large strains between varying- and constant-temperature conditions, and less clearly, between varying- and constant-strain rate conditions. The latter observation, if further confirmed, may lead to isotach formulation of strain rate effects for the investigated range of strain rate (i.e. up to 0.1%/min), where the behavior is largely ductile.Finally, a nondestructive testing method mainly focusing on measurements of stiffness is developed. Different temperatures and axial strain rates were applied in order each time after the specimen was loaded and unloaded in quasi-elastic strain ranges. In the investigated range of conditions, the shear stiffness, averaged from the multiple probes of the same condition, increased linearly with the decrease in temperature, and increased linearly with the logarithmic increase of strain rate.The above observations of behavioral features of frozen and unfrozen soils, with further experimental work, are expected to lead to construction of a unified framework for describing the behavior under both states and transition between them.
