Show moreThis thesis explores and introduces new constructions for non-adaptive group testing which are particulary important for the parameter range we encounter in real life problems. After a summary of existing results, the rst part of this thesis introduces our own constructions, the Latin Square Construction and the Column Augmented Concatenation. Both of these constructions take existing good group testing matrices to create test matrices of larger dimensions. These new matrices are easy to nd for the practical small parameter range we are most interested in. We also address and prove asymptotic results of our Latin Square Construction. In case of the Column Augmented Concatenation the asymptotic results depend greatly on the codes used for the construction. The second part of our work is to address possible ways of augmentation of the Latin Square Construction. Here we explore the di erence in augmentation based on the properties of the starting matrix. In the appendices we give tables of best matrices coming from our constructions with xed, small column weights. We also give a list of the known best 2-disjunct matrices for small row numbers.

Show moreA method of aqueous flooding of subterranean oil bearing formation for tertiary oil recovery involves injecting through a well into the formation a low alkaline pH aqueous sodium bicarbonate flooding solution. The flooding solution's pH ranges from about 8.25 to 9.25 and comprises from 0.25 to 5 weight percent and preferably about 0.75 to 3.0 weight percent of sodium bicarbonate and includes a petroleum recovery surfactant of 0.05 to 1.0 weight percent and between 1 and 20 weight percent of sodium chloride. After flooding, an oil and water mixture is withdrawn from the well and the oil is separated from the oil and water mixture.

Show moreA method for the non-photochemical laser induced nucleation in which short high-intensity laser pulses are used to induce nucleation in supersaturated solutions including protein solutions. The laser induces nucleation only in the area where the beam is focused or passes through, resulting in fewer nuclei than would be achieved by spontaneous nucleation. In addition, the laser reduces nucleation time significantly.

Show moreDoes rhetoric highlighting social norms or mentioning science in a communication affect individuals’ beliefs about global warming and / or willingness to take action? We draw from framing theory and collective-interest models of action to motivate hypotheses that are tested in two large web-based survey-experiments using convenience samples. Our results show that attitudes about global warming, support for policies that would reduce carbon emissions, and behavioral intentions to take voluntary action are strongly affected by norm-based and science-based interventions. This has implications for information campaigns targeting voluntary efforts to promote lifestyle changes that would reduce greenhouse gas emissions.

Show morePaenibacillus strains 32O-W and 32O-Y were attempted to be transformed by electroporation with constructed plasmid pNW33N-vgb, modified to contain the vgb gene which can be expressed as Vitreoscilla hemoglobin. Only attempts with 32O-Y were successful. Transformed 32O-Y/pNW33N-vgb was grown in CDM medium with dibenzothiophene (DBT) as the sole source of sulfur at different temperatures. Dramatic variability was observed in culture at different temperatures, so only the data at 45 °C was analyzed. The growth assay showed that the 32O-Y/pNW33N-vgb strain grew slower than untransformed 32O-Y, although Gibbs assay showed improvements in utilizing ability of DBT of 32O-Y/pNW33N-vgb compared to untransformed 32O-Y. This finding indicated that genetic engineering of introducing vgb into 32O-Y may cause deterioration in cell growth rate but improvement in desulfurization activities. Plasmid pUC-vgb-M2 was transformed into E. coli DH5α. The transformed DH5α/M2-vgb was cultured along with DH5α/pUC8:16, bearing plasmid pUC8:16 that was previously constructed in our lab and can be expressed to produce wild type VHb, and untransformed DH5α. CO-difference spectra were performed with the lysed cultures for the detection of VHb expression. As a result, DH5α/M2-vgb was confirmed to lack the ability to express functional VHb.

Show moreWater is vaporized in an annular upper region of a subsurface formation into which borehole extends from the surface. This creates a substantially nonconducting dielectric in such region extending outwardly from the borehole. Such vaporization is preferably achieved by the application of electrical power to an electrode disposed in the borehole. Liquid is produced through the borehole from a lower region of the formation to cool the lower region near the borehole and maintain an electrically conductive path between the formation and the electrode in such lower region through which electrical power is applied to the formation.

Show moreOxidative and inflammatory stress is associated with chronic disease development and progression. Recent studies suggest that consumption of fruits and vegetables rich in antioxidant compounds attenuate oxidative stress and inflammation. Strawberries are abundant in polyphenolic compounds with antioxidant properties, which have attracted research attention for their possible health benefits. The aim of the project was to determine whether the antioxidant properties of strawberries formulated in a beverage would dose-dependently restore oxidative stress induced by a high fat/ high carbohydrate meal in insulin resistant individuals. Plasma was collected from insulin resistant individuals (n=25) every 30-60 min over 6 h after ingestion after a 650 kcal high fat/ high carbohydrate meal accompanied with a beverage containing 0, 10, 20 or 40 g freeze-dried strawberry powder. The antioxidant capacity of test beverages containing 10, 20 and 40 g strawberry powder were 9.31± 0.66, 19.10 ± 0.60 and 33.57 ± 1.75 μmol Trolox equivalents/mL based on the Oxygen Radical Absorbance Capacity (ORAC) assay. The ORAC value for the placebo (0 g) was below the detectable limits. Biologically relevant oxidative stress was determined using the ORAC assay to estimate antioxidant capacity of the plasma and oxidation of low density lipoprotein (ox-LDL) using an ELISA assay to determine the oxidative damage. Assessment of ox-LDL over 6 hr revealed a significant effect of time (p<0.0001), however no significant difference between the treatment dosages was evident (p>0.05). A marginal treatment by time interaction suggested possible time specific differences between treatments. The evaluation of antioxidant capacity of the plasma was split into assessment of the hydrophilic and lipophilic fractions. Hydrophilic ORAC results showed ix no significant differences between test beverages over 6 hr (p>0.05), including effects of time or treatment by time interactions (p>0.05). The lipophilic ORAC also did not reveal significant differences between treatments (p>0.05). Overall, it appears that beverages with different “doses” of antioxidant capacity did not result in dose-dependent changes in oxidative stress in insulin resistant individuals. There was a trend for protection of ox-LDL by the 20 g strawberry beverage revealed by differences among treatments at 240 min compared to the placebo/0 g strawberry beverage. The findings suggest that antioxidant food properties do not translate directly to plasma antioxidant capacity as measured by ORAC and alternative mechanisms are likely responsible for biological antioxidant effects of strawberry.

Show morePeptidomimetics are a broad class of structural variant synthetic mimics of antimicrobial peptides (AMPs). AMPs are natural antibiotics found in almost entirety throughout all living organisms. Although, AMPs were once thought of as promising therapeutics to combat infectious bacteria, key shortcomings such as low bioavailability, as well as high manufacturing costs have prevented them from reaching a clinical market. Peptidomimetics capitalize on the characteristics of AMPs thought to be responsible for their antibacterial activity, such as net cationic charge and amphiphilicity, while introducing key structural differences. The principal mode of antibacterial activity of AMPs is causing disruption to the bacteria cell membrane of both Gram-positive and Gram-negative bacteria types. The complexities of cell membranes with their various lipid molecule species and proteins makes it difficult to determine mechanistic details of AMPs. It is for this reason model membrane systems such as Langmuir monolayers and supported bilayers composed of the lipid species found in that of actual cell membrane are used. In the present work we have investigated the mechanism of action of different types of peptidomimetics such as N-substituted glycines (peptoids) and oligomers of acylated-lysines (OAKs) on model bacteria and cancer cell membrane systems using various experimental techniques, such as epifluorescence microscopy (EFM), atomic force microscopy (AFM), X-ray reflectivity, and grazing incidence X-ray diffraction (GIXD). From these studies structure function relationships can be obtained, which help aid in the design of new and more effective peptidomimetics. Through these investigations it was found that the substitution of hydrogen atoms for fluorine atoms in the phenyl side chains of cyclic peptoids increases antibacterial on both Gram-positive and Gram-negative model membrane systems, guanidino containing side chains compared to amino containing side chains in α-peptide-β-peptoid chimeras show greater activity on model membrane systems mimicking the cytoplasmic membrane of both Gram-positive and Gram negative bacteria. In addition, insights were gained on the anticancer mechanisms of the naturally occurring AMP magainin-2 and OAK C12K-7α8. The significance of the model membrane system being used cannot be overstated, when the overall arching goal is to bring these peptidomimetics to a clinical market. Thus, the biological relevance of the model membrane system is of great importance. It is this motivation that has lead our research group to develop a floating planar lipid bilayer that is bound to a lipid monolayer functionalized with polyethylene glycol, which to our knowledge has not been previously done. This system and the planar Langmuir monolayer that were used in this work are ideal systems for the use of high energy X-rays that are produced from synchrotron radiation facilities. From such measurements as X-ray reflectivity (XR) and grazing incidence X-ray diffraction (GIXD) molecular scale resolution of the peptidomimetic interactions with the model membrane systems can be achieved.

Show moreThis paper examines a supersonic multi-jet interaction problem that we believe is likely to be important for mixing enhancement and noise reduction in supersonic mixer-ejector nozzles. We demonstrate that it is possible to synchronize the screech instability of four rectangular jets by precisely adjusting the inter-jet spacing. Our experimental data agree with a theory that assumes that the phase-locking of adjacent jets occurs through a coupling at the jet lip. Although synchronization does not change the frequency of the screech tone, its amplitude is augmented. The synchronized multi-jets exhibit higher spreading than the unsynchronized jets, with the single jet spreading the least. We compare the near-field noise of the four jets with synchronized screech to the noise of the sum of four jets operated individually. Our noise measurements reveal that the more rapid mixing of the synchronized multi-jets causes the peak jet noise source to move upstream and to radiate noise at larger angles to the flow direction. Based on our results, we have grounds to believe that screech synchronization is advantageous for noise reduction internal to a mixer-ejector nozzle, since the noise can now be suppressed by a shorter acoustically lined ejector.
