description: Despite the apparent pristine conditions and remoteness of Antarctica, persistent organic pollutants (POPs) have been detected in the Antarctic ecosystem since the 1960s. Today, a variety of organic pollutants can be found in Antarctica, often concentrated in local biota. In this thesis I investigate four system input pathways for POPs to Australian Antarctic territory, Eastern Antarctica. This work has been conducted with the purpose of contributing to an understanding of the possible impacts of these pollutants under present and projected climate conditions, as well as establishing robust baselines from which to monitor temporal and spatial trends. The first long range environmental transport (LRET) pathway investigated was the introduction of POP via long range atmospheric transport (LRAT). Transport was assessed via high flow-through passive air sampling at Casey Station between 2009 and 2013, with sample changeover every 1 to 3 months. The results of this study present the first continuous, multi-year sampling effort for POPs originating from the Eastern Antarctic sector. The POP profile presented is distinct from other regions and is characterised by a dominance of agricultural, rather than manufacturing, chemicals, particularly hexachlorobenzene (HCB) and endosulfan. The study also presents the first reported occurrence of endosulfan in air masses on the Antarctic continent, providing evidence of the LRAT capabilities of this compound. Whilst a moderate data timespan of four years is presented, it is projected that continual monitoring at the decadal scale would be required to detect a 5% change in levels with 80% confidence, emphasising the importance of long term monitoring efforts.

Isotropic photonic band gap and anisotropic structures in transmission spectra of two-dimensional 5-fold and 8-fold symmetric quasiperiodic photonic crystals

description: We measured and calculated transmission spectra of two-dimensional quasiperiodic photonic crystals (PCs) based on a 5-fold (Penrose) or 8-fold (octagonal) symmetric quasiperiodic pattern. The photonic crystal consisted of dielectric cylindrical rods in air placed normal to the basal plane on vertices of tiles composing the quasiperiodic pattern. An isotropic photonic band gap (PBG) appeared in the TM mode, where electric fields were parallel to the rods, even when the real part of a dielectric constant of the rod was as small as 2.4. An isotropic PBG-like dip was seen in tiny Penrose and octagonal PCs with only 6 and 9 rods, respectively. These results indicate that local multiple light scattering within the tiny PC plays an important role in the PBG formation. Besides the isotropic PBG, we found dips depending on the incident angle of the light. This is the first report of anisotropic structures clearly observed in transmission spectra of quasiperiodic PCs. Based on rod-number and rod-arrangement dependence, it is thought that the shapes and positions of the anisotropic dips are determined by global multiple light scattering covering the whole system. In contrast to the isotropic PBG due to local light scattering, we could not find any PBGs due to global light scattering even though we studied transmission spectra of a huge Penrose PC with 466 rods.

description: We analyze a diamond-lattice Hubbard model with the spatially modulated Hubbard interaction. Our dynamical mean-field analysis with special emphasis on non-Hermitian properties elucidates that the gapless nodal line changes into symmetry-protected exceptional torus (SPET) at the Fermi level enclosing the three-dimensional open Fermi surface, which is unique to non-Hermitian physics with chiral symmetry. Furthermore, we also elucidate the effects of the SPETs on the magnetic response; our results based on the random-phase approximation combined with the the dynamical mean-field theory shows that SPETs enhance the magnetic susceptibility at the weakly correlated sites, exemplifying effects of non-Hermitian degeneracies on responses to external fields.

description: The purpose of this research was to explore the decreased physical activity levels exhibited by individuals who are both female and residing in areas of social and economic disadvantage. More specifically, this paper describes the mediating role of technology as an anchor of practice for girls which could both facilitate or inhibit physical activity participation in different instances. Given the significant levels of inactivity in today’s society, it is crucial that providers both understand and utilise technology to maximise its potential as a facilitator of participation, whilst simultaneously limiting its force as an anchor of sedentary practice.

description: VLA observations of OH absorption towards the elliptical galaxy NGC 1052 are presented. Both OH lines, at 1665 and 1667 MHz, were detected in absorption towards the center of NGC 1052. The hyperfine ratio of the two OH lines ($τ$$_{1667}$/$τ$$_{1665}$) is 2.6$\pm$0.8 as compared to 1.8 expected for the excitation under LTE conditions for an optically thin cloud. The column density of OH is estimated to be $2.73(\pm0.26)\times10^{14} cm^{-2}$ assuming $T_{ex} \sim$10 K. The centers of both the OH lines are redshifted from the systemic velocity of the galaxy by $\sim$173 km s$^{-1}$. The velocity of OH line coincides with the velocity corresponding to the strongest HI absorption. We suggest that OH absorption is arising from a molecular cloud falling towards the nucleus. The OH line, though narrower, is found to be within the much broader and smoother H$_2$O megamaser emission. The possible link between OH/HI and $H_2O$ emission is discussed.

description: Materials engineering and nano-manipulation play a key role in the development of advanced Lithium-Sulphur (Li–S) batteries in terms of energy and power density (both gravimetric and volumetric), cycling stability, rate capability, safety and the cost of production. In this thesis, two strategies are used to address the demands, i.e. fabrication of low cost, environmentally benign and conductive carbon-sulphur (C−S) nanostructured cathodes, and the use of interlayers as a novel battery configuration in Li–S battery systems. In the first strategy, inexpensive, scalable, environmentally-friendly and commercial bamboo biochar was activated via a KOH/annealing process to create an abundant microporous structure. This was then used to encapsulate sulphur to prepare a microporous bamboo carbon–sulphur (BC-S) nanocomposite as the cathode for Li–S batteries. The bamboo carbon micropores can encapsulate sulphur and polysulphides to reduce the shuttle phenomenon during cycling while simultaneously maintaining electrical contact between the sulphur and the conductive carbon framework during the charge/discharge process. The treated BC-S (T_BC-S) nanocomposite with 50 wt% sulphur content delivers a high initial capacity of 1295 mA·h·g−1 at a low discharge rate of 160 mA·g−1 and high capacity retention of 550 mA·h·g−1 after 150 cycles at a high discharge rate of 800 mA·g−1 with excellent coulombic efficiency (≥ 95%).

description: This practice-based research paper is an enquiry into the music-making practice of a composer, performer and leader in a small jazz ensemble, to determine what processes, attitudes, and compositional, rehearsal and performance techniques and strategies create an efficacy in realising the score in performance. The intention was to unpack the suppositions and methods contained in the creative act of small jazz ensemble composition within, during and by way of artistic practice, involving the interrelationships between the composer's intention and the musicians' interpretation of a musical score. New musical material was composed to serve as frameworks and as a vehicle for scrutinizing the primary question: How do the processes involved in the composition, development, absorption, interpretation and transferral of musical material from the score to the performance contribute to the development of the artistic practice of a composer/player/leader in a small jazz ensemble? This doctoral study involved the writing, performing and recording of ten original compositions in a small jazz ensemble context. These compositions, influenced by 1960s post-bop and free jazz improvisers/composers such as Miles Davis, Ornette Coleman, Thelonious Monk, Joe Henderson, Wayne Shorter, and John Coltrane, provided material for frameworks. Data informing the exegesis was collected from a reflective diary, reflexive observations, audio/video recordings of public and studio recordings, scores, responses to an open-ended questionnaire by participating musicians, and analyses from a participant/observer perspective. The results of this study will demonstrate how reflecting inward on method and outward (Bartleet, 2009, p. 4) on the perceptions, experience and knowledge of other practitioners, contributes to the development of practice. The creative process in the writing, rehearsal and performance of compositions is defined, explained and demonstrated in the development of artistic practice.
Zodiacal Infrared Foreground Prediction for Space Based Infrared Interferometer Missions

description: The zodiacal foreground for a highly sensitive space infrared interferometer is predicted for various observing locations. For the predictions we use a model that was derived from measurements of the Cosmic Background Explorer (COBE). We find that at a wavelength of $10{\rm μm}$ 96% of the sky is darker than $1{MJy}{\rm sr}^{-1}$ for observations in the ecliptic plane at $5{\rm AU}$, and 83% is darker than $0.1{\rm MJy}{\rm sr}^{-1}$. At $1{\rm AU}$, however, always more than 50% of the sky are brighter than $1{\rm MJy}{\rm sr}^{-1}$, even if the observations are made from $30^\circ$ or $60^\circ$ of latitude above the ecliptic plane, at 10 or $20{\rm μm}$. Thus, according to the employed model, the foreground reduction by increasing the heliocentric distance of the observing location is more effective than by increasing the latitude.

description: The present study deals with teaching the concept and measurement of area. 106 subjects of the 6th grade of Greek Elementary School measured the area of different kinds of shapes. The subjects were divided into two groups, an experimental group and a control group. In the experimental group, area evaluation was taught in a way that highlighted the conceptual characteristics of area measurement. The teaching intervention and the use of different measurement tools led to different measurement strategies. Moreover, the experimental group used more successful strategies than the control group.

description: We investigate the decoupling of heavy right handed neutrinos in the context of an SO(10) GUT model, where a remnant anomalous symmetry is $U(1)_{X}$. In this model the see-saw mechanism which generates the neutrino masses is intertwined with the Stueckelberg mechanism, which leaves the CP-odd phase of a very heavy Higgs in the low energy spectrum as an axion-like particle. Such pseudoscalar is predicted to be ultralight, in the $10^{-20}$ eV mass range. In this scenario, the remnant anomalous $X$ symmetry of the particles of the Standard Model is interpreted as due to the incomplete decoupling of the right handed neutrino sector. We illustrate this scenario including its realisation in the context of SO(10).

description: We present the results of a near-infrared imaging survey of z~3 Lyman Break Galaxies (LBGs). The survey covers a total of 30 arcmin^2 and includes 118 photometrically selected LBGs with K_s band measurements, 63 of which also have J band measurements, and 81 of which have spectroscopic redshifts. Using the distribution of optical {\cal R} magnitudes from previous work and {\cal R}-K_s colors for this sub-sample, we compute the rest-frame optical luminosity function of LBGs. At the brightest magnitudes, where it is fairly well constrained, this luminosity function strikingly exceeds locally determined optical luminosity functions. The V-band luminosity density of only the observed bright end of the z~3 LBG luminosity function already approaches that of all stars in the local universe. For the 81 galaxies with measured redshifts, we investigate the range of LBG stellar populations implied by the photometry which generally spans the range 900--5500 AA in the rest-frame. While there are only weak constraints on the parameters for most of the individual galaxies, there are strong trends in the sample as a whole. A unified scenario which accounts for the observed trends in bright LBGs is one in which a relatively short period of very rapid star-formation (hundreds of M_sun/yr) lasts for roughly 50--100 Myr, after which both the extinction and star-formation rate are considerably reduced and stars are formed at a more quiescent, but still rapid, rate for at least a few hundred Myr. In our sample, a considerable fraction (~20%) of the LBGs have best-fit star-formation ages ~> 1 Gyr, implied stellar masses of ~> 10^10 M_sun, and are still forming stars at \~30 M_sun/yr.

description: The rapid enhancement of central power unit CPU performance enables the development of computationally-intensive healthcare mobile applications for smartphones and wearable devices. However, computationally intensive mobile applications require significant application development time during the application porting procedure when the number of considering target devices operating systems OSs is large. In this paper, we propose a novel retargetable application development platform for healthcare mobile applications, which reduces application development time with maintaining the performance of the algorithm. Although the number of applications target OSs increases, the amount of time required for the code conversion step in the application porting procedure remains constant in the proposed retargetable platform. Experimental results show that our proposed retargetable platform gives reduced application development time compared to the conventional platform with maintaining the performance of the mobile application.

description: The persistence of difficulties caused by misconceptions under - underlying the concept force identified in the learner, is not caused only from his misconceptions, but also, sometimes and especially strengthened by the mathematical approach based on a reduction of the mechanical questions to vector geometry problems, during the transposition of learned knowledge to teach and taught knowledge. In this context, the worst here is that the didactic act instead of conveying knowledge built, generates erroneous conceptions. We show in this paper, with examples to support that language tools (the definition of force, symbolization, selected physical situations, and application’s exercises) involved in the theory of content knowledge to teach are reduced in order to adapt to this mathematical model. Therefore, errors of transmission of force deplored in learner by didacticians are being taught in textbooks of physics. As a result, the persistence of errors in learner is than evident

Cosmological constraints from Planck galaxy clusters with CMB lensing mass bias calibration

description: We present a new cosmological analysis of the galaxy clusters in the Planck MMF3 cosmology sample with a cosmic microwave background (CMB) lensing calibration of the cluster masses. As demonstrated by Planck, galaxy clusters detected via the Sunyaev-Zel'dovich (SZ) effect offer a powerful way to constrain cosmological parameters such as $Ω_{\mathrm{m}}$ and $σ_8$. Determining the absolute cluster mass scale is, however, difficult, and some recent calibrations have yielded cosmological constraints in apparent tension with constraints in the $Λ$CDM model derived from the power spectra of the primary CMB anisotropies. In order to calibrate the absolute mass scale of the full Planck cluster sample, we remeasure the masses of all 433 clusters through their weak lensing signature in the CMB temperature anisotropies as measured by Planck. We perform a joint Bayesian analysis of the cluster counts and masses taking as input the estimated cluster masses, SZ signal-to-noise ratios, and redshifts. Our analysis properly accounts for selection effects in the construction of the cluster sample. We find $σ_8 \left(Ω_{\mathrm{m}}/0.33\right)^{0.25} = 0.765 \pm 0.035$ and $1-b_{\mathrm{SZ}} = 0.71 \pm 0.10$, where the mass bias factor $1-b_{\mathrm{SZ}}$ relates cluster mass to the SZ mass that appears in the X-ray-calibrated cluster scaling relations. We find no evidence for tension with the Planck primary CMB constraints on $Λ$CDM model parameters.

description: Motivated by the recent observation of correlated insulator states and unconventional superconductivity in twisted bilayer graphene, we study the dependence of electron correlations on the twist angle and reveal the existence of strong correlations over a narrow range of twist-angles near the magic angle. Specifically, we determine the on-site and extended Hubbard parameters of the low-energy Wannier states using an atomistic quantum-mechanical approach. The ratio of the on-site Hubbard parameter and the width of the flat bands, which is an indicator of the strength of electron correlations, depends sensitively on the screening by the semiconducting substrate and the metallic gates. Including the effect of long-ranged Coulomb interactions significantly reduces electron correlations and explains the experimentally observed sensitivity of strong correlation phenomena on twist angle.
