▼ High-velocity jetting of acid in carbonate formations as a stimulation technique is an emerging technology currently being studied for applications in long horizontal wells. One way to achieve this is by using limited entry liners and nozzles designed to control the placement of acid along the lateral. Previous field-testing has successfully shown desirable acid distribution along an extended reach well with formation heterogeneities. To support the modeling of this stimulation process, seminal laboratory experiments were previously conducted by jetting 15% (by weight) hydrochloric acid (HCl) through limestone cores. Preceding experimental studies showed the formation of bulb-shaped cavities at the jetted surface, and the propagation of wormholes from these cavities. These initial studies revealed that the formation of cavities and wormholes are greatly affected by jetting velocity, interstitial velocity, and permeability. However, the mechanism of both the cavity formation and wormhole propagation in the core samples still remains unclear. This study aims to better understand these processes by performing acid jetting laboratory experiments with a modified procedure. The new experiments divide acid jetting in multiples stages to produce data snapshots and computed tomography (CT) scan images throughout the cavity and wormhole development in a rock sample. 15% HCl was jetted at constant pressures, with velocities between 107 ft/s and 200 ft/s through six Indiana limestone cores, with permeability measurements ranging from 2.4 mD to 6.9 mD, and porosities around 14%. For each core, multiple jetting stages were conducted until breakthrough stage was reached. Initial interstitial velocity was set at 0.5 cm/min for all cases, which increased to an average of around 1 cm/min around breakthrough point. After each jetting stage, CT scan images and other physical data of the core were obtained before placing it back in the injection setup for the next jetting stage. Injection times for each stage ranged from 1.3 minutes to 4.1 minutes, and each core underwent jetting for three to six stages. CT scan data of the cores were processed and 3D-rendered, producing high-definition multi-angle snapshots of the rock dissolution progression through time. The results clearly demonstrate that cavities and wormholes develop concurrently during acid jetting. It was observed that rock samples with higher permeabilities form larger cavities, and similarly would create larger cavities at higher injection rates. These results are of significant use in future experimental and modeling studies of acid jetting, which are needed for upscaling to well stimulation design in the field.

▼ Acid fracturing is a well stimulation strategy designed to increase the productivity of a producing well. The parameters of acid fracturing and the effects of acid interaction on specific rock samples can be studied experimentally. Acid injection data and fracture conductivity measurements obtained in the research presented in this thesis yielded results that qualified and quantified the impact of a specific acid system on rock samples of varying acid solubility. Six rock samples from a carbonate reservoir were labeled A through F to protect proprietary information included in this research. A 2% potassium chloride solution was used for the acid system and fracture conductivity measurements to prevent clay swelling. Injection temperature, contact time, and injection rate were designed to simulate field treatment conditions. The effects of a chelating agent on fracture conductivity were also studied. Before and after images of the rock samples indicated that the effect of 15% hydrochloric acid on the samples was limited but correlated with the rock acid solubility. Samples E and F had a greater value of acid solubility and showed noticeable surface etching. Samples A, B, and C had lower values of acid solubility and did not show signs of surface etching. Sample D was of moderate acid solubility and showed minimal signs of surface etching. Fracture conductivity did not correlate directly with acid solubility, but likely was a function of inherent matrix permeability based on leak-off measurements and fracture conductivity measurements. Finally, the fracture conductivity of Sample D increased after exposure to a chelating agent. Commonly, acid fracture experimental studies are carried out with outcrop rock samples. The samples have more homogenous properties and without hydrocarbon content. In this study, cores from downhole formation were used. The original condition was preserved as much as possible to simulate real field situations. However, using field rock samples does present challenges not generally associated with outcrop rock samples. Based on the information gathered from the work presented in this thesis, conclusions were drawn concerning the effectiveness of a 15% hydrochloric acid treatment in this formation and the challenges of using field rock samples.

▼ Acid fracture stimulation generates higher well production but requires engineering design for treatment optimization. To quantify the cost and benefit of a particular acid fracture treatment an engineer must predict the resulting fracture???s conductivity, which is based on the etched width created by the injected acid. Etching occurs along the fracture surface but is based on acid flowing through the fracture, so an evaluation tool should describe three-dimensional physics and chemistry. Current practice is to estimate conductivity utilizing two-dimensional models. Unfortunately, these models necessarily assume how acid is distributed in the fracture and often misrepresent the amount of acid etching upon which the conductivity is based. A fully three-dimensional modeling tool to evaluate and predict acid fracture performance across the wide range of carbonate field properties has been developed. The model simulates acid transport and fracture face dissolution. The acid transport model includes the solution of the three-dimensional velocity and pressure fields, the non-Newtonian characteristics of most acid fracturing fluids, and diffusion of acid toward the fracture surface. The model numerically solves the equations describing the three-dimensional acid transport and reaction within a fracture to yield the etched width created by acid along the fracture. The conductivity is calculated with the simulator derived acid-etched width, using correlations recently developed that reflect the small scale heterogeneity of carbonate rock as it creates etching along the fracture surface. The performance of an acid fracture treatment is quantified with conductivity, which is strongly dependent on the etched width created by the acid. This robust new tool more accurately models the impact of design decisions on the acid-etched width and provides a rational path for treatment optimization. Cases typical of industry practice are presented that demonstrate the model capabilities. Advisors/Committee Members: Hill, Alfred D (advisor).

▼ Carnosic acid (CA) is a phenolic terpenoid mainly existed in rosemary, sage and other Labiate herbs. It possesses powerful antioxidant, anti-inflammatory and other health-promoting activities for treating degenerative and chronic diseases. The low solubility and dissolution in aqueous environment of carnosic acid posed a challenge for its application in functional food and accessibility for intestine absorption. The target of my research is to enhance the bioavailability and evaluate bioactivities of carnosic acid by encapsulated in a lecithin based nanoemulsion system. The first part of the research is mainly about the investigation of the properties of carnosic acid and the development of the carnosic acid nanoemulsion (CA-NE). The CA-NE was formulated by medium chain triglycerides as oil phase, lecithin as the emulsifier and prepared by a two-step high speed-high pressure homogenization method. The produced nanoemulsion possess good stability under various pH and low ionic strength conditions. Storage under different temperatures showed good stability of formulated carnosic acid nanoemulsion (CA-NE). The second part of current research is focusing on the bioaccessibility and bioavailability evaluation by in vitro/in vivo models. The pH-stat lipolysis results revealed the nano-emulsified CA was much more bioaccessible than the unformulated CA with 2.8-fold improvement by nanoemulsion system compared with the MCT oil suspension and more than 12-fold compared with the water suspension based on the in vitro lipolysis study. The human gastrointestinal tract (TIM-1) model which simulated the physiological conditions of human upper GI tract revealed that the nanoemulsion greatly improved the oral bioaccessibility of CA by 5.8-fold and indicated a better bioavailability. The pharmacokinetics (PK) study using rats as model animal further showed that the oral bioavailability of carnosic acid enhanced almost 2.2-fold when encapsulated in the nanoemulsion compared with the unformulated CA suspension. Being the first thorough study on nanoemulsion formulation for carnosic acid, by applying two complementary simulation models and animal study, the present research elucidated the reason why nanoemulsion encapsulation would influence the bioavailability of carnosic acid and nanoemulsion proved to be a useful method for improving the oral bioavailability of CA. The third part of my research evaluated the bioactivities of carnosic acid after encapsulation by nanoemulsion system. The antioxidant activity of CA after encapsulation by nanoemulsion decreased from the result obtained by the cellular antioxidant assay (CAA) using HepG2 cells, which mainly attributed to the sustained release and longer endocytosis process as proved by the cellular uptake by confocal laser scanning microscopy. The efficacy on the inhibition on inflammation was conducted using lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Results showed significantly enhanced anti-inflammatory ability of CA-NE with inhibiting the pro-inflammatory cytokines NO… Advisors/Committee Members: HUANG, QINGRONG (chair), HO, CHI-TANG (internal member), Wu, Qingli (internal member), Li, Shiming (outside member), School of Graduate Studies.

▼ Streptococcus mutans is one of the primary causative agents of dental caries in humans. S. mutans ferments dietary sugars in the mouth to produce organic acids. These acids lower local pH values resulting in demineralization of the tooth enamel, leading to caries. To survive acidic environments, S. mutans employs several adaptive mechanisms, including a shift from saturated to unsaturated fatty acids in membrane phospholipids. Evidence suggests that this shift requires de novo fatty acid and phospholipid synthesis; therefore, understanding these synthesis pathways is crucial for understanding how S. mutans adapts to low pH and causes caries. PlsX is an acyl- ACP:phosphate transacylase that links the fatty acid synthesis pathway to the phospholipid synthesis pathway, and is central to the movement of unsaturated fatty acids into the membrane. It has recently been discovered that plsX is not essential in S. mutans. This study explores how the loss of plsX affects the ability of S. mutans to alter its membrane fatty acid profile and survive at low pH. The plsX deletion mutant (ΔplsX) is not a fatty acid or phospholipid auxotroph, indicating that some alternative pathway is capable of carrying out the first step of phospholipid synthesis. Gas chromatography of fatty acid methyl esters (GC-FAME) indicates that deletion of plsX impacts the regulation of fatty acid synthesis, altering the length and saturation of fatty acids. Surprisingly, ΔplsX survives significantly longer than the parent strain, UA159, when subjected to an acid challenge of pH 2.5. This enhanced survival may be due to the increased F-ATPase activity observed at low pH. This enhanced F-ATPase activity may be due to the altered fatty acid profile, or may be part of a response to membrane stress. Supplementing ΔplsX with exogenous unsaturated fatty acids does not restore any wild-type phenotypes; however, incorporation of exogenous fatty acids is 2-fold greater in ΔplsX, compared to UA159. Exogenous oleic acid was observed to decrease survival in acid challenge for both ΔplsX and UA159. These results clearly indicate that the loss of plsX affects both the fatty acid synthesis pathway and the acid-adaptive response of S. mutans.

▼ Currently in the UK, spent nuclear fuel is reprocessed using the PUREX (Plutonium Uranium Reduction Extraction) process. This process generates large amounts of aqueous nitric acid based waste which is reduced in volume by evaporation before being stored in stainless steel tanks pending eventual disposal to a repository after conversion into a solid wasteform. The corrosivity of nitric acid solutions towards these stainless steel storage tanks is strongly affected by the presence of oxidants that can form in situ if certain dissolved metals such as cerium, chromium, ruthenium and neptunium are present, which is invariably the case in nuclear reprocessing plant liquors. Such liquors are, however, subject to radiolysis leading to the formation of nitrous acid and NOx species in equilibrium with nitric acid and water. The redox chemistry of irradiated reprocessing plant liquors is therefore complex, depending on a large number of factors including acidity, nitrate ion concentration, temperature, pressure, radiation dose rate and the nature/concentration of dissolved species. High acidities, high temperatures and low dose rates favour the oxidation of species such as Ce(III). For example, when Ce(IV) forms, the corrosion rate of stainless steel is strongly increased since the reduction of Ce(IV) forms a kinetically-favoured path way. Furthermore, the presence of nitrous acid (which is radiolytically formed from nitrate/nitric acid) can act to reduce potential corrosion accelerators (e.g. Ce(IV)) to their non-oxidising valency states. These dependencies are only semi-quantitatively understood at present, hampering useful prediction of actual effects when conditions are changed. The research presented within this thesis is divided between two experimental campaigns which are interrelated by their applicability to highly active storage tank conditions; I. An investigation into the conditions which effect the radiolytic production of nitrous acid in nitric acid based solutions was undertaken. This included the quantitative measurement of the steady state concentration of nitrous acid experienced under different conditions. The conditions investigated include temperature, dose rate, gaseous headspace and liquor composition in order to elucidate which factors are of importance in estimating the concentration of nitrous acid which can be expected at the base of a highly active storage tank. The major result of this campaign was that nitrous acid data collected could be used to formulate a g-value of nitrous acid formation (which was found to be 0.71) and this value was used to calculate the nitrous acid production rate expected within a highly active storage tank which is a pre-requisite of underpinning the corrosion chemistry within. II. Investigation into the potential formation of in situ corrosion accelerators in a reprocessing liquor simulant was undertaken. For this, a bespoke experimental rig has been designed, built and operated in order to identify the valency of potential corrosion accelerators at high temperatures… Advisors/Committee Members: Pimblott, Simon.

▼ Arachidonic acid (ARA) is a long chain polyunsaturated fatty acid that is routinely added to infant formula with docosahexaenoic acid (DHA) to support neonatal growth and development. Optimal levels of ARA in formula remain to be determined and are based largely on mean worldwide values in breast milk. The objective of this dissertation research was to determine the role of dietary ARA in neonatal development and to evaluate the optimal level in formula to support proper growth and development. Two studies with neonatal domestic pigs were carried out to achieve this objective. The purpose of the first study was to determine the effect of the dietary ARA level on growth, clinical chemistry and immune function, and on tissue ARA and DHA accretion. On day 3 of age, formula-reared (FR) piglets were assigned to 1 of 6 milk replacer formulas containing ARA/DHA as follows (% fatty acid (FA)/FA): (a1) 0.1/1.0; (a2) 0.53/1.0; (a3-d3) 0.69/1.0; (a4) 1.1/1.0; (d2) 0.67/0.62; (d1) 0.66/0.33. No significant differences were observed among the FR groups for growth, hemogram, clinical chemistry or measures of immune status. Heart and liver ARA were responsive to dietary ARA while brain and retina were not. Heart ARA was particularly sensitive to dietary ARA. In the second study, we evaluated two ARA oils for potential use in infant formula compared with a third, commercially available ARA oil. Diets were fed on days 3 - 22 of life and supplied ARA at 0.64% FA and DHA at 0.34% FA. We observed no toxicological effects or differences in growth, and concluded that the experimental ARA oils are safe and bioequivalent to the commercially available ARA source. Overall, results from this dissertation research suggest that the dietary ARA level has a negligible effect on growth and development of the central nervous and immune systems when DHA is supplied near the high end of human breast milk levels (1% FA). The unique responsiveness of the heart to dietary ARA level revealed that ARA accretion is limited by dietary supply. Further investigations are warranted to determine the significance of ARA status on immediate and long term cardiac physiology.

▼ The methylene-interrupted, all-cis (Z) bond configuration is overwhelmingly favored in polyunsaturated fatty acids (PUFA) of vertebrate membranes, particularly the highly unsaturated membranes of electrically-active neural tissue. The hypothesis that hexaene and pentaene homoallylic groups are sterically allowed to follow the groove of a transmembrane [alpha]-helix from bovine rhodopsin using energy minimization (EM) and molecular dynamics (MD) simulations with the GROMOS96 force field was investigated. Docosahexaenoic acid (22:6n-3) and docosapentaenoic acid (22:5n-6) were configured along arbitrary, mid-, top-helix paths along helix 2, with the doubly allylic hydrogens directed inward and the ethylenic hydrogens directed out of the helix. It was shown, by performing EM and MD simulations for 22:6n-3 and 22:5n-6, that the rotationally constrained homoallylic regions are more stably contained within the groove than saturated regions. The analyses of the initial conformations of 22:6n3 in phosphatidylcholine-22:6n-3/34:5n-3 and 22:5n-6 in phosphatidylcholine-22:5n6/34:5n-3, and of conformations of 22:6n-3 in phosphatidylcholine-22:6n-3/34:5n-3 obtained after EM showed that the homoallylic regions fit loosely within the groove while the saturated regions are much closer to the groove boundary. Calculations using a configuration with phosphatidylcholine-22:6n-3/34:5n-3 showed that the 22:6n-3 chain can follow the groove nearest a membrane-water interface, while the homoallylic region of the very long chain 34:5n-3 can follow the groove nearer the membrane center, tethered by its extended saturated region. These results illustrate that the homoallylic polyunsaturated fatty acid motif is not sterically restricted from occupying the groove of a transmembrane [alpha]-helix and provide a testable prediction. The biophysical stability and properties conferred by this configuration was speculated.

▼ Mud acid, which is composed of HCl and HF, is commonly used to remove the formation damage in sandstone reservoirs. However, many problems are associated with HCl, especially at high temperatures. Formic-HF acids have served as an alternative of mud acid for a long period. Several factors may influence the outcome of an acidizing job in sandstone formations. In this research, effects of mineralogy, temperature, and HF concentration were studied. Various clay minerals (kaolinite, chlorite, and illite) were examined to react with formic-HF acid mixtures which contain different concentrations of HF. Coreflood experiments on sandstone cores featured by different mineralogy with dimensions of 1.5 in. x 6 in. were also conducted at a flow rate of 5 cm³/min. Formic or acetic acids were used in preflush stage to remove the carbonates. A series of formic-HF acid mixtures with different ratios and concentrations were tested, and temperature varied from 77 to 350 degrees F. Inductively coupled plasma (ICP), scanning electron microscopy (SEM) and 19F nuclear magnetic resonance (19F NMR) were employed to follow the reaction kinetics and products. Besides, acetic-HF acid system, which is another important alternative of mud acid, was also investigated to compare with formic-HF acids. The species and amounts of reaction products of different clay minerals in organic-HF acids depend on mineral type, acid composition and ratio, and this is further confirmed by coreflood experiments, in which sandstone cores with different mineral compositions give quite different responses to the same acid mixture. As preflush, formic acid becomes more effective in removing carbonate minerals in sandstone cores at higher temperatures. In main flush stage, more concentrated HF can react with more clay minerals, but can also cause higher risk of CaF2 precipitate. Both formic-HF and acetic-HF acids are much milder than mud acid. When reacting with clay minerals, there is no big difference in the behaviors of 13 wt% acetic-HF acids and 9 wt% formic-HF acids, as long as the HF concentrations are the same.

▼ Unlocking a tight carbonate formation for oil and gas production by multi-stage acid stimulation is a relatively cost-effective method as an alternative to propped fracturing for production enhancement. Depending on whether treatment pressure is below or above the formation closure stress, acid stimulation is basically divided into matrix acidizing and acid fracturing. In this study, practical methodology to evaluate both matrix acidizing and acid fracturing through treatment monitoring is presented respectively. For matrix acidizing, monitoring and optimizing a matrix acidizing has been achieved by integrating a forward model used in acidizing design for horizontal wells with a real-time monitoring model for skin evolution during the stimulation. The effect of acidizing is described as an overall skin factor change, and productivity improvement is predicted for the treatment. Then the field treatment data monitored on-site was used to estimate the skin response by treatment injection. History matching procedure of design and actual treatment data will be carried out to update near-wellbore and key wormholing parameters. Through sensitivity study, which parameter should be updated is discussed. Finally optimum rate schedule is identified based on updated parameters. Meanwhile, for acid fracturing treatment, new method for real-time monitoring of acid fracturing, the inverse injectivity vs. superposition time function plot is proposed, subject to the condition that the treatment pressure is above closure pressure after the breakdown. Combining a linear dual-porosity transient slab model with injectivity concept, actual growing cross-sectional area induced by acid fracturing treatment can be monitored in real-time. After production starts, linear flow diagnostic approach with rate-transient analysis provides cross-sectional area flowing from matrix, which is compared with the area induced by acid fracturing during the stimulation. The treatment efficiency provides engineers with additional information as to whether the designed acid fracturing was performed appropriately under the in-situ closure stress field. A field case example of both multi-stage matrix acidizing and acid fracturing acid in horizontal well are also presented respectively in the study to illustrate the application of the approach developed, and to show the value of the integrated approach to monitor and diagnose acid stimulation in horizontal wells.

▼ The potential for conjugated linoleic acid (CLA) incorporation into pressure-sensitive adhesive (PSA) formulations was evaluated. A series of free radical bulk copolymerizations of CLA/styrene (Sty) and CLA/butyl acrylate (BA) were designed to allow the estimation of reactivity ratios. Bulk terpolymerizations of CLA/Sty/BA were also evaluated before moving to emulsion terpolymerizations of CLA/Sty/BA. The polymers were characterized for composition, conversion, molecular weight and glass transition temperature while latexes were characterized for viscosity, particle size, tack, peel strength, and shear strength. All experiments were performed at 80 °C and monitored with attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. While bulk experiments were monitored off-line, the emulsion experiments were monitored in-line. Absorbance peaks related to the monomers and polymer were tracked to provide conversion and polymer composition data using a multivariate calibration method. Off-line measurements using gravimetry and 1H-NMR spectroscopy were compared to the ATR-FTIR data and no significant differences were detected between the measurement methods. Pseudo-kinetic models, developed and validated with the copolymer experimental data, were used to estimate reactivity ratios. The copolymer pseudo-kinetic models were extended to a terpolymer pseudo-kinetic model and validated with experimental data. The pseudo-kinetic models incorporated the ability of oleic acid, a common impurity found in CLA, to trap electrons thus influencing the reaction kinetics significantly. The influence of terpolymer composition, chain transfer agent concentration, cross-linker concentration, molecular weight, viscosity and particle size on tack, peel strength and shear strength was investigated by using a constrained mixture design. The final forms of the resulting empirical models allowed the creation of 3D response surfaces for PSA performance optimization. The incorporation of 30 wt.% CLA into a practical PSA application suitable for the removable adhesives category was achieved.

As much as 10% of the US population will experience at least one bout of depression within their lifetime. It has been reported that an increased time spent with major depressive disorder (MDD) results in a decreased volume in the hippocampus. This decreased volume is the result of apoptosis, or programmed cell death. In recent years it has become known that new neurons (neurogenesis) are continuously born in the hippocampus of humans. In fact, it now appears that antidepressant drug efficacy may be dependent on adult neurogenesis in the hippocampus. At least six epidemiological studies have shown an inverse correlation between seafood intake and prevalence of mood disorders (p [less than]0.05 or better). There is mounting evidence that this result is due to fish oils containing the long-chain, poly-unsaturated, omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Although extensive study has been undertaken using both of these omega-3s together, very little has been done to determine which fatty acid has the greater effect. Although previously thought to be readily interconvertible, there is mounting evidence that these two lipids are not treated equally in the body. EPA has produced greater cell proliferation over DHA in the B-lymphocyte cells, and DHA has even been known to cause a decrease at higher concentrations. Differences have also been reported in both molecular and behavioral outcomes. This research tested the hypothesis that EPA facilitates proliferation and survival of neuronal precursor cells to a greater extent than does DHA. Human neuronal precursor cells were grown in the presence of EPA, DHA, and varying ratios of EPA and DHA to determine their dose-response relationships. While there were no large effects on proliferation or differentiation, EPA, but not DHA, protected cells from iron-induced oxidative stress. This protection appears to be, at least in part, the result of altered p53 translocation in EPA-treated cells. Future work will be needed to determine the role of this molecular protection in the antidepressant activity of EPA.

▼ This study is the first one to examine the reaction of citric acid with calcite over a wide range of parameters. Its main focus is to study the effects of different parameters such as initial citric acid concentration and temperature on the citric-calcite reaction. A rotating disk apparatus was used to study the reaction of calcite (CaC0₃) with citric acid. Using the rotating disk theory, the calcite dissolution rates in citric acid solutions were evaluated as a function of rotating speed, initial concentration of citric acid, concentration of magnesium (Mg²⁺) & Iron (Fe³⁺) ions, temperature, and pressure. In addition, Scanning Electron Microscopy (SEM) technique was used to explore the precipitation mechanism of calcium citrate during the reaction of citric acid with calcite. Using this technique, several factors affecting the precipitation of calcium citrate were identified. In this research, citric acid was found to be an effective stimulation fluid at pH values < 4, rotational speeds of (100-1,000 rpm), initial citric acid concentration of 1-7.5 wt%, pressure values of 1,000-1,500 psi, and temperatures of 25-50 °C. However, SEM analysis has shown that calcium citrate precipitation occurred during the reaction at the calcite disk. The precipitation of calcium citrate was found be function of disk rotational speed, initial citric acid concentration, and the concentration of both Mg²⁺ and Fe³⁺ ions. More calcium citrate precipitated at high rotational speeds and high initial citric acid concentration. The presence of both Mg²⁺ and Fe³⁺ ions minimized the precipitation of calcium citrate. The rate of calcite dissolution in citric acid was found to be mainly dependent on the rotational speed. In general, at low rotational speeds, below 500 rpm, the calcite dissolution is mainly governed by the mass-transfer rate, while at high rotational speed, above 500 rpm, it is controlled by the surface-reaction rate. The mass-transfer and the surface-reaction mechanism were investigated thoroughly. Using the rotating disk theory, the overall mass transfer coefficient was determined at various rotational speeds, initial citric acid concentrations, and temperature values. The effective diffusion coefficient of citric as was determined at various citric acid concentrations and various temperature values. In addition, the apparent activation energy of calcite dissolution in mass-transfer regime was found to be 37.9 kJ/mol. Finally, a simplified expression was developed to model the reaction kinetics of citric acid with calcite. The model parameters: reaction order, and activation energy were found to be 0.833 and 63.1 kJ/mol, respectively. This study highlights the importance of the initial acid concentration, temperature, and calcium citrate precipitation on the citric acid reaction with calcite. Another important outcome is the effect of various key parameters on the performance of citric acid as a stand-alone stimulation fluid at conditions similar to those present in a typical field case.

▼ vii ABSTRACT EFFECT OF RATION ON FATTY ACID PROFILES IN BEEF by Amber Marie Phillips Abbott Master of Science in Interdisciplinary Studies: Animal Science California State University, Chico Fall 2010 There are a number of agricultural by-products produced throughout the food production chain that retain some nutritive value, and as such, could be utilized as livestock feeds in a sustainable system. Many of these by-products are composed of complex carbohydrates that can be bio-transformed through the rumen into high quality protein for human consumption. Ruminal bio-conversion of rice bran, almond hulls, and spent brewers grains means that there will be less of these materials occupying limited space in landfills, and would also serve as a bioremediation measure for these ???industrial bio-hazardous materials??? as described by the Environmental Protection Agency (EPA). This study was conducted to assess the impact of agro-industrial by-products as feeds on the nutritional value of beef as reflected in fatty acid profiles, including brewer???s grains, rice bran and almond hulls, all by- products common to the Western Region of the United States. These finishing rations were contrasted to grass-fed and grain-fed cattle, two viii conventional practices with known effects on lipid profile. The higher energy rations (grain and brewer???s grain) increased the efficiency of weight gain and reduced days on feed, while the lower energy diets of grass-only and rice bran/almond hulls significantly altered the fatty acid profile in the final meat product in a manner that can be considered beneficial to human health. The grass-finished and rice bran/almond hull ration decreased the total lipid content, while increasing conjugated linoleic acid (CLA) and omega-3 fatty acid concentration. In addition, rice bran and almond hulls achieved a more beneficial SFA ratio, similar to grass-finished beef, with a lower concentration of cholesterol elevating C14:0 myristic acid and a higher concentration of cholesterol neutral C18:0 stearic acid. The use of agro-industrial by-products like rice bran and almond hulls not only supports a healthier lipid profile, but increases the average daily gain, therefore decreasing the days on feed as compared to grass. Although the brewer???s grain by-product did not produce a significantly different lipid profile from the grain ration, it did tend to have a better overall lipid profile than the traditional grain-fed beef. In an effort to produce protein that is affordable, nutritious and sustainable, agricultural by-products can be used as feeds to improve the nutrition and efficiency of production while decreasing the impact on the environment.

Formic acid and nitric acid have been found to contribute to aerosol formation and are key components of acidity in the troposphere. Tropospheric measurements of these species are often limited, resulting in major uncertainties when assessing their effects on the climate. Current global chemistry-transport models significantly under-predict formic acid concentrations, particularly in the mid-to-high latitudes of the Northern Hemisphere. Furthermore, large discrepancies exist in the role played by dinitrogen pentoxide on nitric acid production between two recently documented models assessing the global nitric acid budget. In order to accurately constrain the budget of these acids in the mid-to-high latitudes of the Northern Hemisphere, it is crucial that these uncertainties are addressed. In this work, airborne measurements of formic acid, nitric acid and dinitrogen pentoxide are presented from across different regions of the Northern Hemisphere to investigate direct and indirect sources contributing to the formic acid and nitric acid regional budgets. Measurements were collected using a Chemical Ionisation Mass Spectrometer (CIMS) fitted to the Facility for Atmospheric Airborne Measurements (FAAM) BAe-146 aircraft. Formic acid measurements within the European Arctic during March and July 2012 would indicate ocean sources dominate over terrestrial sources irrespective of seasonality. CH2I2 photolysis and oxidation was hypothesised as a marine source of formic acid. Modelled estimates would indicate the CH2I2 reaction route may represent a significant summer marine source of formic acid within the Fenno-Scandinavian Arctic. Additionally, low altitude aircraft measurements taken within the Fenno-Scandinavian Arctic over regions occupied by wetlands in August 2013 were used to calculate a formic acid surface flux. Results would suggest formic acid emission from wetlands may represent up to 37 times greater than its globally inferred estimate. A flux measurement conducted over a comparable region in September 2013 observed a negative flux, indicating a change of this region from a net source to a net sink of formic acid. The inconsistency of this regional wetland source confirms the need for in-depth studies on formic acid emission from wetlands, in order to better understand its contribution to the regional and global formic acid budget. In a separate study, significant daytime elevations of N2O5 and HNO3 concentrations were observed within identified biomass burning plumes off the eastern coast of Canada. In-plume correlations between N2O5 and HNO3 concentrations observed within these environments suggest N2O5 was acting as additional daytime source of gaseous HNO3 when subjected to photolytically-limited conditions. This result has important implications to ozone production and provides evidence for an additional daytime source of nitric acid, which must be included in chemistry models calculating the global nitric acid budget.

▼ In mammalian tissues, cells are surrounded by the extracellular matrix (ECM) – a complex network of proteins, glycosaminoglycans (GAGs) and proteoglycans (PGs). The ECM regulates numerous crucial processes such as cell proliferation, differentiation, migrations, and a variety of signaling events. Synthetic extracellular matrices (sECMs) were developed in an attempt to mimic the properties of natural ECMs, specifically for tissue engineering applications. Several sECMs are not commercially available. We compared these materials side by side in a representative array of assays, to test their biological performances and user-friendliness. Our results indicate that the ECM composition and compliance greatly influence cell behavior. Based on these data, we underline the need for a paradigm shift from classical two-dimensional (2D) culturing to the more relevant, in vivo-like three-dimensional (3D) techniques especially for applications directly translatable to clinical applications. Haloacetate-modified hyaluronan (HA) polymers were synthesized and characterized in an effort to provide a greater variety of sECM components. A novel approach was employed that yielded “chemically-reversed,” electrophilic HA polymers that could be readily crosslinked with a variety of available nucleophiles. The new haloacetate-modified hyaluronan materials show dose-dependent mild cytotoxic effects and appear promising for adhesion prevention or medical device coating. A novel thiol-modified hyaluronan polymer (HASH) was also synthesized. These biomaterials are not crosslinkable, are well tolerated by cell and shows promising results in a rat arthritis model, by slowing down the disease progression rate. sECMs emerged to be particularly suitable for application such as drug screening. To this end, Extracel ™, a hyaluronan and gelatin-based crosslinked hydrogel was used to examine the effect of alpha-substituted lysophosphatidic acid (LPA) analogs. LPA and its synthesizing enzyme autotaxin (ATX) were associated in numerous studies with aberrant cellular behavior, mostly associated with cancer and tumorigenicity. The compounds tested show cell-line dependent and LPA receptor-specific effect in cell proliferation assays. Further studies that address modulation of cellular invasiveness and metastatic potential are needed for a complete profiling of these chemicals.

▼ Plant hormone abscisic acid (ABA) plays a main role in coordinating various stress signals in plants. ABA regulates the expression of genes and activities of enzymes in response to various stress conditions. In the following studies we were able to study the ABA mediated regulation of enzymes in plants. Using in-gel activity analysis we identified that ABA regulates the activity of aspartate aminotransferase (AAT), an enzyme involved in nitrogen assimilation and carbohydrate metabolism. Our results indicate that phosphorylation of AAT by SnRK2.2 and 2.3 kinases results in down regulation of AAT2 and AAT3 isozyme activities in Arabidopsis. AAT was identified as a negative regulator of drought stress and <i>aat</i> mutant plants showed improved survival following drought conditions. Using in-gel staining method we were able to visualize sugar phosphatases like fructose 1-6 bisphosphatase family, sedoheptulase-1,7-bisphosphatase, inositol mono phosphatases; protein serine/threonine phosphatases, protein tyrosine phosphatases and studied their response to ABA and drought stress. Fructose-1-6 bisphosphatase family of phosphatases were identified to be induced by ABA in Arabidopsis and rice. N-acetylglucosamine (GlcNAc) is present on glycoproteins and as post translational modification (PTM) in cytoplasmic and nuclear proteins. N-acetylglucosamine is removed from target proteins by hexosaminidases. Little is known about the hexosaminidases in plants. Using in-gel activity analysis we were able to identify an ABA induced Beta-hexosaminidase with a neutral pH optimum in soybean. The nuclear DNA in chromatin is associated with basic proteins called histones. The N-terminal tails of histones contain different PTMs including methylation, phosphorylation, ubiquitination, acetylation, ADP-ribosylation and glycosylation. The histone lysine methylation can serve as a binding site or repel/disrupt the histone binding proteins. The effector/reader proteins specifically recognize the post translational modifications and responsible for the downstream process. Many histone methyl modification effector proteins have been characterized but very few proteins whose binding was disrupted by the presence of a PTM were identified. Using peptide pulldown analysis, far western analyses we identified a WD-40 domain containing histone binding (HB01) protein as direct interactor of unmodified histone. The presence of post translational modifications disrupts HB01 binding to histone H3. Advisors/Committee Members: Din-Pow Ma (committee member), Daniel G.

▼ The study of target proteins in live cells is fundamentally important to understanding their molecular roles in biological processes. Applications of cell permeable small molecules in bioorthogonal reactions have been improved to selectively label proteins tag for the purpose of protein interaction analysis. Bioorthogonal reaction is defined as the chemical reactions that do not react or interfere with biological systems. Functional groups that involve in bioorthogonal reactions must selectively react with each other under physiologically conditions. Also using a small reactive molecule in bioorthogonal reactions can prevent the structural perturbation of the proteins that wants to be monitored. Molecule fluorophores can provide dynamic information on cell surface interactions due to their small size, low detection limits and environmental sensitivity. Boronic acids have been applied in the construction of receptors and chemosensors for a range of biologically important species, especially saccharides. In 2009, for the first time, Schepartz utilized a rhodamine–derived bisboronic acid sensor (RhoBo) as a reversible, selective and non-toxic sensor to selectively label a specific tetraserine peptide. In this thesis, simple monoarylboronic acids with potentially four covalent, reversible points of attachment were designed and synthesized to test their binding affinity to a small peptide tag in a sequence specific manner. Boronate ester formation between serines and the boronic acid part of the molecule was believed to potentially increase the selectivity and stability of imine formation between the lysine and ketone part of the molecule. Binding affinity of designed boronic acids towards a selection of chosen peptides was evaluated via the Alizarin Red S colorimetric assay and UV spectrophotometry and fluorescence spectroscopy. In Chapter 2 small boronic acid molecules with Michael acceptors were designed in which the boronic acid part of the molecule was employed as a way to increase site-specificity of the thiol-Michael addition reactions towards small peptide tag containing cysteine and serine residues. 3-Maleimidophenylboronic acid was found to be reactive towards small peptides containing cysteine and terminal serine residues. Reaction kinetics were performed to monitor its reactivity towards the peptide by HPLC-MS and 1H NMR spectroscopy.
