Abstract:
Abstract The existence of unbounded solutions and their asymptotic behavior is studied for higher order differential equations considered as perturbations of certain linear differential equations. In particular, the existence of solutions with polynomial-like or noninteger power-law asymptotic behavior is proved. These results give a relation between solutions to nonlinear and corresponding linear equations, which can be interpreted, roughly speaking, as an asymptotic proximity between the linear case and the nonlinear one. Our approach is based on the induction method, an iterative process and suitable estimates for solutions to the linear equation.

Full text
Abstract:
One of the pressing needs in the field of disease biomarker discovery is new technologies that could allow high performance protein analysis in different types of clinical material, such as blood and solid tissues. This thesis includes four approaches that address important limitations of current technologies, thus enabling highly sensitive, specific and parallel protein measurements. Paper I describes a method for sensitive singleplex protein detection in complex biological samples, namely solid phase proximity ligation assay (SP-PLA). SP-PLA exhibited improved sensitivity compared to conventional sandwich immunoassays. We applied SP-PLA to validate the potential of GDF-15 as a biomarker for cardiovascular disease.   Paper II describes ProteinSeq, a multiplexed immunoassay based on the principle of SP-PLA, for parallel detection of 36 proteins using next-generation sequencing as readout. ProteinSeq exhibited improved sensitivity compared to multiplexed sandwich immunoassays, and the potential to achieve even higher levels of multiplexing while preserving a high sensitivity and specificity. We applied ProteinSeq to analyze 36 proteins, including one internal control, in 5 μl of plasma samples in a cohort of patients with cardiovascular disease and healthy controls. Paper III describes PLA-DTM, a strategy for recording all possible interactions between sets of proteins in clinical samples. Individual proteins and their interactions are first encoded to dual barcoded DNA by PLA, and the barcodes are interrogated by a method named dual tag microarray (DTM). We applied the method for studying interactions among protein members of the NFκB signaling pathway. Paper IV describes a novel probing strategy for analyzing individual biomolecules in solution or in situ. The technique employs a new class of probes for unfolding proximity ligation assays - uPLA probes. The probes are designed so that each probe set is sufficient in forming and replicating circular DNA reporter, without interactions among themselves when incubated with the sample. The uPLA probing strategy provides ease in the design of multiple probe sets in parallelized assays while enhancing the specificity of detection. We used the uPLA probes to detect various targets, including synthetic DNA and cancer-related transcripts in situ.

Abstract:
Traction motors are thermally pressed to obtain a high torque per unit volume at the same time as a relatively high frequency is used. Because of the high frequency the phenomenon skin effect and proximity effects appear, this is explored in the thesis. To find a link between the parasitic and thermal effects on the insulation is important. In this thesis, a finite element model of the Flux 2D suitable for skin effect analysis is developed; also a thermal network has been developed to find thermal hotspots in the stator slot. In this thesis, sinusoidal supplies for two operating points are studied and triangular sinusoidal PWM supply is as well studied for the nominal operating point.

The scope of this thesis is to study the stability of two ships in close proximity towing. Unlike previous studies in the past, the lateral dynamics of both ships are included in the formulation. The equations of motion of the system consist of the sway and yaw motions of the two ships and a control law for the leading ship. An eigenvalue stability analysis of the coupled system confirms the results that are obtained through numerical simulations. It is shown that it is possible for the system to be unstable even through the classical criteria for the towing stability are satisfied. A series of parametric studies is conducted in order to analyze the sensitivity of the system for different towline lengths, tension, and control time constant.

Full text
Abstract:

A novel technology for protein detection, proximity ligation, has been developed along with improved methods for in situ synthesis of DNA microarrays. Proximity ligation enables a specific and quantitative transformation of proteins present in a sample into nucleic acid sequences. As pairs of so-called proximity probes bind the individual target protein molecules at distinct sites, these reagents are brought in close proximity. The probes consist of a protein specific binding part coupled to an oligonucleotide with either a free 3’- or 5’-end capable of hybridizing to a common connector oligonucleotide. When the probes are in proximity, promoted by target binding, then the DNA strands can be joined by enzymatic ligation. The nucleic acid sequence that is formed can then be amplified and quantitatively detected in a real-time monitored polymerase chain reaction. This convenient assay is simple to perform and allows highly sensitive protein detection. Parallel analysis of multiple proteins by DNA microarray technology is anticipated for proximity ligation and enabled by the information carrying ability of nucleic acids to define the individual proteins. Assays detecting cytokines using SELEX aptamers or antibodies, monoclonal and polyclonal, are presented in the thesis.

Microarrays synthesized in situ using photolithographic methods generate impure products due to damaged molecules and interrupted synthesis. Through a molecular inversion mechanism presented here, these impurities may be removed. At the end of synthesis, full-length oligonucleotides receive a functional group that can then be made to react with the solid support forming an arched structure. The 3’-ends of the oligonucleotides are then cleaved, removing the impurities from the support and allowing the liberated 3’-hydroxyl to prime polymerase extension reactions from the inverted oligonucleotides. The effect of having pure oligonucleotides probes compared to ones contaminated with shorter variants was investigated in allele specific hybridization reactions. Pure probes were shown to have greater ability to discriminate between matched and singly mismatched targets at optimal hybridization temperatures.

Abstract:
High quality reagents are preconditions for high performance protein analyses. But despite progress in some techniques, e.g. mass spectrometry, there is still a lack of affinity-based detection techniques with enhanced precision, specificity, and sensitivity. Building on the concept of multiple affinity recognition reactions and signal amplification, a proximity ligation assay (PLA) was developed as a molecular tool for analyzing proteins and their post-translational modification and interactions. PLA enhanced the analysis of protein expression levels and post-translational modifications in western blotting (Paper I), which had elevated sensitivity and specificity, and an ability to investigate protein phosphorylation. A general and straightforward method was established for the functionalization of affinity reagents through adding DNA strands to protein domains for protein analysis in medicine (Paper II). A method for protein domain-mediated conjugation was developed to simplify the use of recombinant affinity reagents, such as designed ankyrin repeat protein (DARPin), in DNA-mediated protein analyses. Alzheimer’s disease (AD) is characterized by progressive cognitive decline and memory impairment, and amyloid-beta plaques and neurofibrillary tangles (NFT) in the brain are clinical hallmarks of the disease. In order to understand the mechanisms underlying the formation of NFT, in situ PLA was used to explore the role of microtubule affinity related kinase 2 (MARK2) in phosphorylating tau protein during the pathological progress of AD (Paper III). The analyses of roles of MARK proteins 1-4 in phosphorylating tau protein in cells and in post-mortem human brains were performed in Paper IV. The focus of this thesis was the study of post-translational modifications and interactions of proteins in medicine. Procedures for high performance protein analysis in western blotting via proximity ligation were developed, and a functionalization method for recombinant affinity reagents in DNA-mediated protein analysis was established. These and other techniques were used to investigate the roles of tau-phosphorylating MARK family proteins in AD.

Abstract:
Fundamental to all biological processes is the interplay between biomolecules such as proteins and nucleic acids. Studies of interactions should therefore be more informative than mere detection of expressed proteins. Preferably, such studies should be performed in material that is as biologically and clinically relevant as possible, i.e. in primary cells and tissues. In addition, to be able to take into account the heterogeneity of such samples, the analyses should be performed in situ to retain information on the sub-cellular localization where the interactions occur, enabling determination of the activity status of individual cells and allowing discrimination between e.g. tumor cells and surrounding stroma. This requires assays with an utmost level of sensitivity and selectivity. Taking these issues into consideration, the in situ proximity-ligation assay (in situ PLA) was developed, providing localized detection of proteins, protein-protein interactions and post-translational modifications in fixed cells and tissues. The high sensitivity and selectivity afforded by the assay's requirement for dual target recognition in combination with powerful signal amplification enables visualization of single protein molecules in intact single cells and tissue sections. To further increase the usefulness and application of in situ PLA, the assay was adapted to high content analysis techniques such as flow cytometry and high content screening. The use of in situ PLA in flow cytometry offers the possibility for high-throughput analysis of cells in solution with the unique characteristics offered by the assay. For high content screening, it was demonstrated that in situ PLA can enable cell-based drug screening of compounds affecting post-translational modifications and protein-protein interactions in primary cells, offering superior abilities over current assays. The methods presented in this thesis provide powerful new tools to study proteins in genetically unmodified cells and tissues, and should offer exciting new possibilities for molecular biology, diagnostics and drug discovery.

Abstract:
Along with proteins, a myriad of different molecular biomarkers, such as post-translational modifications and autoantibodies, could be used in an attempt to improve disease detection and progression. In this thesis, I build on several iterations of the proximity ligation assay to develop and apply new adaptable methods to facilitate detection of proteins, autoantibodies and post-translational modifications. In paper I, we present an adaptation of the solid-phase proximity ligation assay (SP-PLA) for the detection of post-translational modification of proteins (PTMs). The assay was adapted for the detection of two of the most commons PTMs present in proteins, glycosylation and phosphorylation, offering the encouraging prospect of using detection of PTMs in a diagnostic or prognostic capacity.  In paper II, we developed a variant of the proximity ligation assay using micro titer plate for detection and quantification of protein using optical density as readout in the fluorometer, termed PLARCA. With a detection limit considerably lower than ELISA, PLARCA detected femtomolar levels of these proteins in patient samples. In paper III, we aim to compare detection values of samples collected from earlobe capillary, venous plasma, as well as capillary plasma stored in dried plasma spots (DPS) assessed with a 92-plex inflammation panel using multiplex proximity extension assay (PEA). Despite the high variability in protein measurements between the three sample sources, we were able to conclude that earlobe capillary sampling is a suitable less invasive alternative, to venipuncture. In paper IV, we describe the application of PLARCA and proximity extension assay (PEA) for the detection of GAD65 autoantibodies (GADA). Thus, offering highly sensitive and specific autoimmunity detection.

The purpose of this thesis is to develop an efficient analysis and design procedure for assessing the seakeeping behavior of surface ships in close proximity towing. The problem is formulated by using the heave and pitch equations of motion in regular waves. The vertical plane relative motions between the trailing and the leading ships are matched through the speed-resistance characteristics of the trailing ship. A sea state degradation factor is introduced. This factor characterizes the expected seakeeping performance penalty resulting from the connection. A series of parametric studies is conducted for various geometric properties and environmental characteristics. The results can be used to evaluate the response of the system and provide insight into parameter selection for motion minimization.

In this paper we analyze fundamental local-area communication issues related to proximity operations around near-earth asteroids. We are motivated by NASA's plan to send robotic spacecraft to numerous such asteroids in the coming years in preparation for an eventual manned mission. We consider here the case where multiple probes are deposited on the surface of an asteroid and must communicate the data they collect to each other and to earth by using the orbiting `mothership' as a relay. With respect to this scenario, we statistically analyze the ability of surface probes in various locations to communicate with the mothership as well as their abilities to network with one another. For the purposes of this analysis, we assume the simplest possible communications scenario: a surface probe can communicate with the mothership only when it has an unobstructed line of sight. At the frequencies of interest here, line of sight is a necessary condition but it is obviously not sufficient - the end-to-end link margins of our communications system must be high enough to support the desired/required data rates. The work presented in this paper extends our previous research in which we only analyzed the visibility of the locations on the surface of the asteroid. Here, we consider how visibility affects the required communications bandwidth and buffer sizes for both surface-to-spacecraft and surface-to-surface scenarios.

Abstract:
Abstract In this study, a segment of water conveyance system at a chemical manufacturing facility is under investigation. The pipe segment under investigation conveys a daily average flow of five million gallons of water per day (MGD) from the river to a water treatment plant. The exact age of the pipe system is unknown as limited construction or maintenance information exists. The study area is a pipe segment near the treatment plant where three flow restrictions exist within a 30-foot distance bounded by a T-junction and a water filtration plant. These restrictions include two self-actuated butterfly valves and an orifice plate on a 16-inch diameter steel pipe, buried approximately three feet below ground surface. When standing in the study area, heavy vibrations are felt at the ground surface. The valves and orifice plate are to control flowrate and reduce pressure from 80 PSI to 45PSI as the flow enters the water treatment plant. Flow restrictions in close proximity can cause cavitation, water hammer and other flow phenomena within a pipe system. This can result in excessive wear of the pipe’s inner walls and valves which may compromise the structural integrity and/or function of the system. Computational fluid dynamics (CFD) software is a useful tool for determining if the conditions for the various flow phenomena are present in a system. The flow characteristics were numerically calculated in MATLAB then computationally modeled in AFT Fathom. The purpose of the numerical analysis was to describe the stability of the fluid flow at discrete points in the pipe network and identify the network segments with significantly unstable flow profiles. The purpose of the AFT Fathom CFD model purpose was to provide a continuous simulation of the flow stability in the pipe segment and provide a more robust description of the flow profiles in the network. While Fathom cannot explicitly predict cavitation or water hammer, the kinematic parameters produced by the Fathom model and the physical conditions observed in the study indicate that water hammer is likely occurring.

Abstract:
Wollongong’s geographic proximity to the southern sprawl of Sydney, accessible transport and cultural diversity have been an attractor for many inward bound creative migrants, helping it diversify away from its industrial past. Wollongong City Council, understanding the importance of the creative industries, has been very proactive in ensuring that the heart of the city has been well and truly activated by sectors of these industries, while the University of Wollongong and its Innovation Campus have also proved a boon to both specialist and embedded creatives. Wollongong maintains a balance between traditional creatives and newer tech-oriented operatives, most with local, national and international suppliers and clients.

Abstract:
To promote active transportation modes (such as bike ride and walking), and to create safer communities for easier access to transit, it is essential to provide consolidated data-driven transportation information to the public. The relevant and timely information from data facilitates the improvement of decision-making processes for the establishment of public policy and urban planning for sustainable growth, and for promoting public health in the region. For the characterization of the spatial variation of transportation-emitted air pollution in the Fresno/Clovis neighborhood in California, various species of particulate matters emitted from traffic sources were measured using real-time monitors and GPS loggers at over 100 neighborhood walking routes within 58 census tracts from the previous research, Children’s Health to Air Pollution Study - San Joaquin Valley (CHAPS-SJV). Roadside air pollution data show that PM2.5, black carbon, and PAHs were significantly elevated in the neighborhood walking air samples compared to indoor air or the ambient monitoring station in the Central Fresno area due to the immediate source proximity. The simultaneous parallel measurements in two neighborhoods which are distinctively different areas (High diesel High poverty vs. Low diesel Low poverty) showed that the higher pollution levels were observed when more frequent vehicular activities were occurring around the neighborhoods. Elevated PM2.5 concentrations near the roadways were evident with a high volume of traffic and in regions with more unpaved areas. Neighborhood walking air samples were influenced by immediate roadway traffic conditions, such as encounters with diesel trucks, approaching in close proximity to freeways and/or busy roadways, passing cigarette smokers, and gardening activity. The elevated black carbon concentrations occur near the highway corridors and regions with high diesel traffic and high industry. This project provides consolidated data-driven transportation information to the public including: 1. Transportation-related particle pollution data 2. Spatial analyses of geocoded vehicle emissions 3. Neighborhood characterization for the built environment such as cities, buildings, roads, parks, walkways, etc.

Abstract:
The textile and apparel industry is a highly globalized, multi-trillion-dollar sector. Today, production networks are dominated by low-cost Asian countries with very large labor-pools, which has made it increasingly difficult for other producers around the world to compete, including those in Latin America and the Caribbean (LAC). While the region has participated in the industry, there are currently no LAC countries amongst the leading ten exporters. The COVID-19 pandemic, together with rising geopolitical tensions between the US and China, however, has disrupted this well-established business model over the past two to three years. This creates the most significant opportunity of the past decade to reconfigure the geography of the supply chain; as a small, but long-term supplier, with proximity to the worlds largest single market, Central America is well-positioned to benefit from these changes. Nonetheless, the region needs to upgrade various aspects of their GVC participation in order to become a serious contender in the reconfiguration of the industry. Key policies should focus on developing human capital through industry-specific training initiatives; intensifying investment attraction efforts; and aggressively investing in both hard and soft infrastructure to reduce barriers to trade and enhance lead time responsiveness.

Abstract:
This study considers existing off-grid initiatives that are being implemented in support of more rapid electrification in sub-Saharan Africa. After first reviewing the successes and obstacles of commonly implemented off-grid solutions, we suggest groundwater irrigation powered via off-grid solar (OGS) systems as a productivity-focused electrification solution that could be valuable to off-grid development initiatives moving forward. This solution encourages the establishment of OGS pumping infrastructure in unelectrified areas in proximity to nonirrigated agriculture that have promising and sustainable groundwater abstraction potential. Using open-access spatial data to estimate the alignment of these resources is an important first step in determining potential study sites for on-the-ground research and pilot projects. This study focuses on applying the above approach to Ethiopia to produce a spatial layer representing areas that are recommended for further assessment of their OGS groundwater irrigation viability. We follow the spatial analysis with a projection of potential gains from investment in OGS groundwater pumping systems under different scenarios to highlight the solution’s viability with regional context. This assessment provides an initial methodology for identifying, examining, and expanding upon potential markets where OGS irrigation can become an economically viable solution.

Abstract:
Geelong and the Surf Coast are treated here as one entity although there are marked differences between the two communities. Sitting on the home of the Wathaurong Aboriginal group, this G21 region is geographically diverse. Geelong serviced a wool industry on its western plains, while manufacturing and its seaport past has left it as a post-industrial city. The Surf Coast has benefitted from the sea change phenomenon. Both communities have fast growing populations and have benefitted from their proximity to Melbourne. They are deeply integrated with this major urban centre. The early establishment of digital infrastructure proved an advantage to certain sectors. All creative industries are represented well in Geelong while many creatives in Torquay are embedded in the high profile and economically dominant surfing industry. The Geelong community is serviced well by its own creative industries with well-established advertising firms, architects, bookshops, gaming arcades, movie houses, music venues, newspaper headquarters, brand new and iconic performing and visual arts centres, libraries and museums, television and radio all accessible in its refurbished downtown area. Co-working spaces, collective practices and entrepreneurial activity are evident throughout the region.

Abstract:
Thurgood Canyon, located on White Sands Missile Range (WSMR), contains an alluvial fan that is bisected by a primary installation road and is in the proximity of sensitive fish habitats. This project was initiated to determine if and how sensitive fish habitats at the base of the fan are impacted by the existing drainage infrastructure and to assess the condition and sustainability of the existing transportation infrastructure. Findings show that the current drainage infrastructure maintains flow energy and sediment carrying capacity further down the fan than would occur in its absence. However, frequent to moderately rare (small to medium) flood events dissipate over 2 km from sensitive habitat, and overland flow and sediment do not reach the base of the fan. Controlled flow diversion is recommended upstream of the road to mitigate infrastructure or habitat impacts during very rare (very large) flood events. A comprehensive operation and management approach is presented to achieve sustainable transportation infrastructure and reduce the likelihood of impacts to the sensitive habitat.

Stratigraphy, facies heterogeneities, and structure in the Montney Formation of northeastern British Columbia: relation to H2S distribution. Natural Resources Canada/CMSS/Information Management, 2022. http://dx.doi.org/10.4095/329796.

Full text
Abstract:
In the last decade, the Lower Triassic Montney Formation of the Western Canada Sedimentary Basin (WCSB) has undergone significant development, providing a rich dataset to study structural, stratigraphic, and facies control on the variations in hydrogen sulphide (H2S) gas content. Splitting the siltstone dominated Montney into the three regional members (i.e., Lower Montney, Middle Montney, and Upper Montney) allows for detailed analysis on the enrichment of H2S within a local-scale study area in northeastern British Columbia (BC). Within this study area, Upper Montney H2S content increases within individual parasequences both up-dip and towards the east. In addition to potential up-dip migration, there may be greater sulphur-bearing components in the east, allowing for the sulphate reduction required to generate H2S. The overlying Middle Triassic thins eastward, providing proximity to the overlying anhydrite-rich beds of the Upper Triassic Charlie Lake Formation. Further, the overlying Middle Triassic Sunset Prairie Formation has an erosional edge that corresponds with eastern elevated H2S concentrations within the Upper Montney unit. Mapped structures are syn-depositional to the Middle Triassic, potentially providing conduits for early sulphate-rich fluid migration. In the Middle and Lower Montney, elevated H2S generally occurs with proximity to the top of the Permian Belloy Formation. Within this study area, limited Lower Montney data is available and thus needs to be further corroborated with regional data. Both the Middle and Lower Montney display elevated H2S in trends that generally align with mapped faults. The faults may have acted as conduits for sulphate-rich fluids to migrate during early burial then migrate laterally through facies that may have been permeable during early burial, such as the carbonate-rich facies at the boundary between the Middle and Lower Montney. Further core and isotope analyses are required to fully understand this relationship.

Abstract:
This report is comprised of five substantive elements. The first is crafting a scientifically sound framework for identifying landscapes within the metropolitan areas we studied. The second is applying those Place Typologies and spatial analysis to economic and demographic change for the transit system in each metropolitan area. The third is analyzing how real estate markets respond to transit system proximity with special reference to the Place Typologies. Fourth, this is followed by specialized studies into how urban form and society are shaped by transit systems. The fifth is providing an overall perspective of our research as well as a framework for unlocking the potential to leverage economic benefits of transit to advance social well-being.
