<p><p>This project aims in building a new experimental setup for capacitive measurements of a pH-Sensor. PAA-IOA (Poly Acrylic Acid co – Iso Octyl Acrylate) is the dielectric material over the in-plane interdigitated gold electrodes where PAA IOA acts as an H<sup>+</sup> ion sensing layer. The changes in the capacitance of the sensor when the sensor is dipped into different pH solutions will be quantized accordingly. The dipping setup is built in such a way that the electrodes (containing the polymer layer) can be easily dipped into different pH liquids and to eliminate any contact between the

Abstract:
Time-dependent queueing models are important since most of real-life problems are time-dependent. We develop a numerical approximation algorithm for the mean, variance and higher-order moments of the number of entities in the system at time t for the Ph(t)/Ph(t)/s/c queueing model. This model can be thought as a reparameterization to the G(t)/GI(t)/s. Our approach is to partition the state space into known and identifiable structures, such as the M(t)/M(t)/s/c or M(t)/M(t)/1 queueing models. We then use the Polya-Eggenberger distribution to approximate certain unknown probabilities via a two-m

Abstract:
A deterministic change to a time-varying queueing model is described as either changing the number of entities, the queue capacity, or the number of servers in the system at selected times. We use a surrogate distribution for N(t), the number of entities in the system at time t, to approximate deterministic changes to the Ph(t)/Ph(t)/1/c and the Ph(t)/M(t)/s/c queueing models. We develop a solution technique to minimize the number of state probabilities to be approximated.<br>Master of Science

Abstract:
Abstract Glycans, as a part of glycoproteins, glycolipids and other glycoconjugates, are involved in many vital intra- and inter-cellular tasks, such as protein folding and sorting, protein quality control, vesicular trafficking, cell signalling, immunological defence, cell motility and adhesion. Therefore, their correct construction is crucial for the normal functioning of eukaryotic cells and organisms they form. Most cellular glycans are constructed in the Golgi, and abnormalities in their structure may derive, for instance, from alkalinization of the Golgi lumen. In this work we show th

Abstract:
The classical isoelectric trapping (IET) technique, using the multicompartment electrolyzer (MCE), has been one of the most successful electrophoretic techniques in preparative-scale protein separations. IET is capable of achieving high resolution discrimination of proteins, by isolating proteins in between buffering membranes, in their isoelectric state. However, due to the inherent nature of the IET process, IET has suffered several shortcomings which have limited its applicability. During a classical IET separation, a protein gets closer and closer to its pI value, thus the charge of the pr

Abstract:
Abstract The presence of acetic and formic acids in the produced water of gas condensate wells has been known for some time by the industry. In traditional water analysis, it has been titrated and reported as alkalinity. The calculation of accurate downhole pH values requires that these ions be analyzed separately in the water and that an organic acid material balance be performed on all three phases in the separator. In this manner, it is then possible to use phase distribution coefficients involving ionic equilibrium to determine how these acids distribute themselves between phases as the pH

Abstract:
Abstract The pH stabilization technique is a method for control of sweet corrosion in wet gas pipelines. The method is suited for systems with MEG for hydrate control as the pH stabilizer will remain in the lean MEG and do not need a continuous injection. Full pH stabilization is used when the risk for production of formation water is negligible as formation water will lead to calcium carbonate scaling. Partial pH stabilization combined with a film forming inhibitor may be an alternative when some formation water may be produced. This method has also been applied without MEG. The biggest chall

Abstract:
ABSTRACT Stress corrosion cracking (SCC) continues to be a safety concern, mainly because it may remain undetected before a major pipeline failure occurs. SCC processes involve complex interactions between metallurgy, stresses, and the electrolyte chemistry beneath the disbonded coating. For these reasons, assessing SCC failure probability at any given location on a pipeline is difficult. In addition, data uncertainties make the prediction of SCC even more challenging.

Abstract:
Abstract Acetic and formic acids have been found in the separator water of gas condensate wells containing CO2 and they are titrated as alkalinity. Traditional pH equations which neglect these acids and calculate pH based on alkalinity greatly over-predict the downhole pH. Since all scale calculations depend on an accurate pH value, a more sophisticated method of calculation has been developed. The methodology can be used to calculate the in-situ bulk pH and the saturation pH at different depths within a well. The difference in the saturation pH and the bulk pH is the delta pH, a negative delt

Key unresolved issues related to the mechanisms of high-pH and near-neutral-pH stress-corrosion cracking (SCC) were identified based upon a review of the technical literature. It was determined that the mechanism of high-pH SCC is well understood, the key outstanding issue being related to the factors that affect the micro-creep properties of a steel, which seem to be the primary determinant of its susceptibility to SCC. The mechanism of near-neutral-pH SCC is not so well understood. Both dissolution and hydrogen appear to be involved, but their relative roles remain to be determined. Some exp
