description: An extensive culture-dependent and -independent study was conducted to identify microorganisms contributing to the biogeochemical cycling of manganese (Mn) in Ashumet Pond, a freshwater pond in Massachusetts currently undergoing remediation. A variety of bacteria (including Gamma-, Beta-, and Alpha-proteobacteria, Firmicutes, and Bacteroides) and Ascoymete fungi were isolated from the pond that promote Mn(II) oxidation and subsequent formation of Mn(III/IV) oxide minerals. Targeted-amplicon pyrosequencing of the bacterial and fungal communities associated with Mn oxide-encrusted samples show a highly diverse microbial community, of which the cultured phylotypes represent a minor proportion. This suggests a larger community, not identified through culturing, contributes to Mn oxide formation within the Pond.

description: Cumulus, Cumulus-percent, Altocumulus, Cirrocumulus, and Cumulus-white are mammogram risk scores (MRSs) for breast cancer based on mammographic density defined in effect by different levels of pixel brightness and adjusted for age and body mass index. We measured these MRS from digitized film mammograms for 593 monozygotic (MZ) and 326 dizygotic (DZ) female twin pairs and 1592 of their sisters. We estimated the correlations in relatives (r) and the proportion of variance due to genetic factors (heritability) using the software FISHER and predicted the familial risk ratio (FRR) associated with each MRS. The ρ estimates ranged from: 0.41 to 0.60 (standard error [SE] 0.02) for MZ pairs, 0.16 to 0.26 (SE 0.05) for DZ pairs, and 0.19 to 0.29 (SE 0.02) for sister pairs (including pairs of a twin and her non-twin sister), respectively. Heritability estimates were 39% to 69% under the classic twin model and 36% to 56% when allowing for shared non-genetic factors specific to MZ pairs. The FRRs were 1.08 to 1.17. These MRSs are substantially familial, due mostly to genetic factors that explain one-quarter to one-half as much of the familial aggregation of breast cancer that is explained by the current best polygenic risk score.

description: Human exposure to particulate matter (PM) air pollution is associated with human morbidity and mortality. The mechanisms by which PM impacts human health are unresolved, but evidence suggests that PM intake leads to cellular oxidative stress through the generation of reactive oxygen species (ROS). Therefore, reliable tools are needed for estimating the oxidant generating capacity, or oxidative load, of PM at high temporal resolution (minutes to hours). One of the most widely reported methods for assessing PM oxidative load is the dithiothreitol (DTT) assay. The traditional DTT assay utilizes filter-based PM collection in conjunction with chemical analysis to determine the oxidation rate of reduced DTT in solution with PM. However, the traditional DTT assay suffers from poor time resolution, loss of reactive species during sampling, and high limit of detection. Recently, a new DTT assay was developed that couples a particle-into-liquid-sampler with microfluidic-electrochemical detection. This “on-line” system allows high temporal resolution monitoring of PM reactivity with improved detection limits. This study reports on a laboratory comparison of the traditional and on-line DTT approaches. An urban dust sample was aerosolized in a laboratory test chamber at three atmospherically relevant concentrations. The on-line system gave a stronger correlation between DTT consumption rate and PM mass (R2 = 0.69) than the traditional method (R2 = 0.40) and increased precision at high temporal resolution, compared to the traditional method.

description: The refractive index is a fundamental property controlling aerosol optical properties. Secondary organic aerosols have variable refractive indices, presumably reflecting variations in their chemical composition. Here, we investigate the real refractive indices (mr) and chemical composition of secondary organic aerosols (SOA) generated from the oxidation of α-pinene and limonene with ozone and NOx/sunlight at different HC/NOx ratios. Refractive indices were retrieved from polar nephelometer measurements using parallel and perpendicular polarized 532-nm light. Particle chemical composition was monitored with a high-resolution time-of-flight aerosol mass spectrometer (HR-Tof-AMS). For photochemically generated SOA, the values of refractive indices are consistent with prior results, and ranged from about 1.34 to 1.55 for limonene and from 1.44 to 1.47 for α-pinene, generally increasing as the particles grew. While AMS fragments are strongly correlated to the refractive index for each type of SOA, the relationships are in most cases quite different for different SOA types. Consistent with its wide range of refractive index, limonene SOA shows larger variations compared to α-pinene SOA for most parameters measured with the AMS, including H:C, O:C, f43 (m/z 43/organic), fC4H7+, and others. Refractive indices for α-pinene ozonolysis SOA also fell in narrow ranges; 1.43–1.45 and 1.46–1.53 for particles generated at 19–22 and 23–29°C, respectively, with corresponding small changes of f43 and H:C ratio and other parameters. Overall, H:C ratio, m/z 43 and 55 (C2H3O+, C4H7+) were the best correlated with refractive index for all aerosol types investigated. The relationships between mr and most fragments support the notion that increasing condensation of less oxygenated semivolatile species (with a possible role for a concomitant decrease in low refractive index water) is responsible for the increasing mrs observed as the experiments progress. However, the possibility that oligomerization reactions play a role cannot be ruled out.

description: Adhesion between dust particles and indoor surfaces can lead to negative effects on human health by triggering allergic and asthmatic reactions. In this study, adhesion forces of indoor office dust and activated carbon (AC, as model soot) particles to four common indoor materials (Al, Cu, PVC, and glass) were measured by colloidal probe atomic force microscopy. Chemical analysis of office dust shows it is largely made up of oxygenated hydrophilic organic carbon material. Both metal surfaces experienced weaker dust and AC adhesion than PVC or glass by up to 2–12 times lower primarily due to the presence of attractive electrostatic forces in the latter two (non-conducting) surfaces. Dust and AC adhesion were also highly sensitive to surface roughness, with an inverse relationship between adhesion force and roughness due to the reduction in contact area between the particle and a rougher material surface. Capillary forces play only a minor or negligible role in dust and AC surface adhesion. Adhesion models utilizing a purely van der Waals approach such as the simple Hamaker model and modified Rumpf's model are insufficient to determine the actual particle-surface contact radii and requires the accounting of non-van der Waals forces to adhesion.

description: The Jing Ltd. miniature combustion aerosol standard (Mini-CAST) soot generator is a portable, commercially available burner that is widely used for laboratory measurements of soot processes. While many studies have used the Mini-CAST to generate soot with known size, concentration, and organic carbon fraction under a single or few conditions, there has been no systematic study of the burner operation over a wide range of operating conditions. Here, we present a comprehensive characterization of the microphysical, chemical, morphological, and hygroscopic properties of Mini-CAST soot over the full range of oxidation air and mixing N2 flow rates. Very fuel-rich and fuel-lean flame conditions are found to produce organic-dominated soot with mode diameters of 10–60 nm, and the highest particle number concentrations are produced under fuel-rich conditions. The lowest organic fraction and largest diameter soot (70–130 nm) occur under slightly fuel-lean conditions. Moving from fuel-rich to fuel-lean conditions also increases the O:C ratio of the soot coatings from ∼0.05 to ∼0.25, which causes a small fraction of the particles to act as cloud condensation nuclei near the Kelvin limit (κ ∼ 0–10−3). Comparison of these property ranges to those reported in the literature for aircraft and diesel engine soots indicates that the Mini-CAST soot is similar to real-world primary soot particles, which lends itself to a variety of process-based soot studies. The trends in soot properties uncovered here will guide selection of burner operating conditions to achieve optimum soot properties that are most relevant to such studies.

title: ‘Tension, apprehension, and dissension have begun’: Crises of Identity in the Cold War Writings of Alfred Bester, 1950-1960
Creators: name: Cobb, MA
Publisher: name: University of Liverpool Repository
Year: 2016

description: Between 1950 and 1960, Alfred Bester produced numerous works which utilised his contemporary Cold War atmosphere in order to examine and extrapolate the current cultural state. The purpose of this thesis is to offer a reading of Bester’s works which focuses exclusively on the portrayal of psychology and the exploration of identity crises in relation to the split self. Designed to demonstrate Bester’s unique approach to the self as inherently split between the social and the personal, this thesis understands the Cold War as a collective neurosis, and uses this model as a framework for its examination of psychology. As such, this thesis aims to demonstrate that Bester’s use of psychology expresses the universal nature of compulsions and literature’s importance in depicting genuine human characters. The impact of nuclear weapons and the Cold War state of anxiety, paranoia, and suspicion on the human psyche is widely recognised and examined through the lens of identity. However, Bester’s particular approach utilises this understanding of identity to depict the reciprocal nature of individual and political psychology. One of the key arguments presented here is that Bester’s portrayal of universal psychology is designed to mirror the Cold War state of tension and anxiety against individual psychological pressures. Conformity or isolation are extrapolated to exacerbate a loss of self that can only be regained through reconciliation between the public and private spheres. Thus, Bester’s approach is designed to argue that such reconciliation is required in order to break down barriers of the ‘other’ and dissuade collective delusions of normality. This thesis argues that Bester’s approach to psychology develops and foreshadows the growing awareness that individuals may not be in control of their own mind, and the importance of human understanding in extrapolating and predicting the future of society. By depicting the Cold War as collective neurosis, Bester’s works mirror social identity crises against individual crises in order to depict the impact of social influence and the place of the individual within society. Tracing the development of this approach, this thesis examines Bester’s works chronologically from 1950 through 1960. With the intention of establishing Bester’s commitment to his approach, this thesis has expanded beyond his fiction to include his non-fiction, such as letters, editorials, interviews, and essays, as well as crossing genre lines between his sf and mainstream writing. Not only is Bester’s understanding of psychology thereby revealed and charted, but an exploration of the ability of various modes of writing to examine psychology is undertaken, as is an overview of the general literary atmosphere in which Bester was working.

description: The performance of electrostatically charged blown microfiber filter media was characterized for high-volume sampling applications. Pressure drop and aerosol collection efficiency were measured at air pressures of 55.2 and 88.7 kilopascals (kPa) and filter face velocities ranging from 2.5 to 11.25 meters per second (m/s). Particle penetration was significant for particles above 0.5 micrometers (μm) in aerodynamic diameter where the onset of particle rebound was observed as low as 200 nanometers (nm). Particle retention was enhanced by treating filters in an aqueous solution of glycerol. Adding this retention agent eliminated electrostatic capture mechanisms but mitigated inertial rebound. Untreated filters had higher nanoparticle collection efficiencies at lower filter face velocities where electrostatic capture was still significant. At higher filter face velocities, nanoparticle collection efficiencies were higher for treated filters where inertial capture was dominant and particle rebound was mitigated. Significant improvements to microparticle collection efficiency were observed for treated filters at all air flow conditions. At high air pressure, filter efficiency was greater than 95% for particles less than 5 μm. At low air pressure, performance enhancements were not as significant since air velocities were significantly higher through the fiber mat. Measured single fiber efficiencies were normalized by the theoretical single fiber efficiency to calculate adhesion probability. The small fiber diameter (1.77 μm) of this particular filter gave large Stokes numbers and interception parameters forcing the single fiber efficiency to its maximum theoretical value. The adhesion probability was plotted as a function of the ratio of Stokes and interception parameter similar to the works of others. Single fiber efficiencies for inertial nanoparticle collection were compared to existing theories and correlations. Copyright 2014 American Association for Aerosol Research

The immunopathology of chronic suppurative lung disease in Northern Territory children
Creators: name: Pizzutto, Susan
Publisher: name: Charles Darwin University
Year: 2015

description: Northern Territory Indigenous children experience a high burden of chronic suppurative lung disease (CSLD) associated with recurrent lower respiratory infection. There are currently limited data to guide effective long-term management strategies for CSLD. This thesis investigates the role of the immune response, particularly in relation to non-typeable Haemophilus influenzae (NTHi), in the pathogenesis of chronic suppurative lung disease in Northern Territory children. The findings from this thesis provide biological evidence in support of novel management strategies to improve the clinical outcome for Northern Territory children with CSLD. Principal findings: 1. A prospective evaluation study showed that flexible bronchoscopy with lavage substantially contributes to the clinical management of children with CSLD by identifying airway eosinophilia and respiratory pathogens not addressed by current empiric therapies. 2. In vitro studies of innate, and adaptive immune responses to NTHi showed that: a. Children with CSLD generate a functionally distinct cell-mediated immune phenotype in response to NTHi compared with respiratory-healthy children. b. The NTHi-driven cytokine profile in children with CSLD is associated with mechanisms regulating inflammation in the lungs. 3. A study of children vaccinated with a Pneumococcal H. influenzae Protein D conjugate vaccine provided proof-of-concept that the functional immune profile can be modified in children with CSLD. The findings from this thesis contribute to the development of novel management strategies for CSLD in Northern Territory children by identifying factors of the immune response, likely contributing to the pathogenesis of CSLD, that may be targeted by novel therapeutic interventions. These data lay the foundation for studies to evaluate the effect of novel interventions on the clinical outcomes of Northern Territory children with CSLD.

description: Absorption enhancement and shadowing effects were investigated for nigrosin-laden quartz (fibrous), Teflon (matted), and polycarbonate (membrane) filters in inert surroundings at different sample steady-state temperatures and particle mass loadings. Sample absorptivity was determined using a novel laser-heating technique, which is based on perturbing the sample steady-state temperature and monitoring the thermal response during decay back to steady state, along with a model for thermal energy conservation. In addition, transmissivity measurements were carried out to enable determination of the sample absorption coefficient. The results indicated that the isolated-nigrosin absorption coefficient decreased with steady-state temperature and increased with mass loading and filter pore size. Comparing the absorption coefficient for both the isolated nigrosin and nigrosin-laden filters, indicated that absorption enhancement was most significant for the Teflon filters and least significant for the polycarbonate filters. The effect became more significant as the pore size decreased, steady-state temperature increased, and particle mass loading decreased. The decrease in the isolated-nigrosin, mass-specific absorption cross-section with heavier sample loadings was attributed to shadowing effects.

In this study, adhesion forces of indoor office dust and activated carbon (AC, as model soot) particles to four common indoor materials (Al, Cu, PVC, and glass) were measured by colloidal probe atomic force microscopy. Chemical analysis of office dust shows it is largely made up of oxygenated hydrophilic organic carbon material. Both metal surfaces experienced weaker dust and AC adhesion than PVC or glass by up to 2–12 times lower primarily due to the presence of attractive electrostatic forces in the latter two (non-conducting) surfaces. Dust and AC adhesion were also highly sensitive to surface roughness, with an inverse relationship between adhesion force and roughness due to the reduction in contact area between the particle and a rougher material surface. Capillary forces play only a minor or negligible role in dust and AC surface adhesion. Adhesion models utilizing a purely van der Waals approach such as the simple Hamaker model and modified Rumpf's model are insufficient to determine the actual particle-surface contact radii and requires the accounting of non-van der Waals forces to adhesion.

Frequency up- and down-conversion by parametric and non-parametric processes in warm rubidium vapour
Creators: name: Rahaman, Nafia
Publisher: name: Swinburne
Year: 2024

description: This thesis presents an experimental study of nonlinear frequency up- and down-conversion in warm rubidium vapour at modest intensities of the applied laser light. We studied the properties and optical amplification of the amplified spontaneous emission. Our results may improve the performance of the laser-guide-star technique. Our examination also reveals that despite continuous-wave (cw) and quasi-cw two-photon excitation, the directional blue emission generated by parametric four-wave mixing exhibits a spiking behaviour. This needs to be considered in emerging applications in the field of quantum information and technology. Additionally, we explored the usage of a laser as an optical switch.

description: The performance of electrostatically charged blown microfiber filter media was characterized for high-volume sampling applications. Pressure drop and aerosol collection efficiency were measured at air pressures of 55.2 and 88.7 kilopascals (kPa) and filter face velocities ranging from 2.5 to 11.25 meters per second (m/s). Particle penetration was significant for particles above 0.5 micrometers (μm) in aerodynamic diameter where the onset of particle rebound was observed as low as 200 nanometers (nm). Particle retention was enhanced by treating filters in an aqueous solution of glycerol. Adding this retention agent eliminated electrostatic capture mechanisms but mitigated inertial rebound. Untreated filters had higher nanoparticle collection efficiencies at lower filter face velocities where electrostatic capture was still significant. At higher filter face velocities, nanoparticle collection efficiencies were higher for treated filters where inertial capture was dominant and particle rebound was mitigated. Significant improvements to microparticle collection efficiency were observed for treated filters at all air flow conditions. At high air pressure, filter efficiency was greater than 95% for particles less than 5 μm. At low air pressure, performance enhancements were not as significant since air velocities were significantly higher through the fiber mat. Measured single fiber efficiencies were normalized by the theoretical single fiber efficiency to calculate adhesion probability. The small fiber diameter (1.77 μm) of this particular filter gave large Stokes numbers and interception parameters forcing the single fiber efficiency to its maximum theoretical value. The adhesion probability was plotted as a function of the ratio of Stokes and interception parameter similar to the works of others. Single fiber efficiencies for inertial nanoparticle collection were compared to existing theories and correlations. Copyright 2014 American Association for Aerosol Research

Publisher: name: Swinburne
Year: 2024

description: A consistent trend can be seen in attempts to bring communication technologies not just to urban communities, but to rural regions as well. Systems such as Television White Space come up in these attempts as a valid option due to its ability to operate for long distances and transmit well through obstacles. A microstrip antenna is fabricated for this research to operate in the Television White Space frequency range and its effectiveness is analyzed. Its feasibility is compared with similar microstrip antennas and with the commercially used log-periodic antenna variety, using the Free Space Path Loss formula and Hata model.

description: Absorption enhancement and shadowing effects were investigated for nigrosin-laden quartz (fibrous), Teflon (matted), and polycarbonate (membrane) filters in inert surroundings at different sample steady-state temperatures and particle mass loadings. Sample absorptivity was determined using a novel laser-heating technique, which is based on perturbing the sample steady-state temperature and monitoring the thermal response during decay back to steady state, along with a model for thermal energy conservation. In addition, transmissivity measurements were carried out to enable determination of the sample absorption coefficient. The results indicated that the isolated-nigrosin absorption coefficient decreased with steady-state temperature and increased with mass loading and filter pore size. Comparing the absorption coefficient for both the isolated nigrosin and nigrosin-laden filters, indicated that absorption enhancement was most significant for the Teflon filters and least significant for the polycarbonate filters. The effect became more significant as the pore size decreased, steady-state temperature increased, and particle mass loading decreased. The decrease in the isolated-nigrosin, mass-specific absorption cross-section with heavier sample loadings was attributed to shadowing effects.

description: Diabetic retinopathy (DR) is a progressive condition that can cause vision loss. It starts out subtly and gets worse with time.  It affects approximately 35% of people with diabetes worldwide.  According to research, a new case of diabetic retinopathy is diagnosed every few minutes. In its early stages, retinal images are frequently difficult to recognize due to their complexity. In the area of medical imaging, Deep Learning is growing.  Convolutional Neural Networks (CNN) and other architectures are used in this study to see how they can be used to accurately detect and classify the stages of diabetic retinopathy. Our approach utilizes publicly available datasets and several deep learning techniques are used to identify and categories the Fundus images into four stages of DR will be compared in this work.  Model robustness is enhanced using data preprocessing methods like normalization, augmentation, and segmentation. The models are evaluated using performance metrics like accuracy, precision, recall, F1-score, and Area under Curve (AUC).  The results demonstrate that deep learning models can achieve high classification accuracy, outperforming traditional machine learning methods.  Ophthalmologists may find it easier to comprehend model predictions if they are able to gain insight into the regions of interest that are essential for decision-making through visual interpretation of the models. This study underscores the potential of deep learning to revolutionize diabetic retinopathy diagnosis, offering a foundation for future research in integrating multi-modal data and real-world applications.
