Effect of wall confinement on the aerodynamics of bluff bodies
Creators: name: El-Sherbiny, Saad El-Sayed
Publisher: name: University of British Columbia
Year: 2011

description: The effect of wall confinement on the aerodynamics of a set of stationary circular cylinders and flat plates, representing the blockage ratio range of 3 - 35.5%, is investigated experimentally to obtain data on mean and unsteady pressure distributions, Strouhal number, and wake geometry. In general, the influence of the Reynolds number in the range of 10⁴ -12 x 10⁴ was found to be confined to the mean pressure distribution at the higher blockage (circular cylinder only) and the unsteady surface loading. The results showed the base pressure to decrease and consequently the drag coefficient to increase with bluffness; however, the pressure distribution in the potential flow region remained relatively unaffected by the confinement. The wake geometry does not change appreciably under constraint and thus leads to a similarity of the several flow parameters. Variation in the vortex shedding frequency was found to be essentially proportional to the increase of separation velocity in accordance with Roshko's universal Strouhal number. The shape of the fluctuating surface pressure distribution curves also remains unaffected by the constraint. However, the pressure intensity increases with an increase in bluffness and shows considerable dependence on the Reynolds number and the three-dimensionality of the flow. Validity of the correction methods due to Glauert and Maskell for the mean drag coefficient is checked in the light of the experimental results. They were found to be inadequate particularly at higher blockage ratios. However, modification of these methods through inclusion of the higher order terms improved their applicability. Least square fit of the results showed linear variation [e.g., C[sub D] = C[sub D[sub c]] + Const (C[sub D] S/C)] of the parameters. A potential flow model is developed for two-dimensional symmetrical bluff bodies under wall confinement. It provides a procedure for predicting the mean surface loading on a bluff body over a range of blockage ratios. Experimental results with normal flat plates and circular cylinders for blockage ratios up to 35.5% substantiate the validity of the approach.

description: We investigate a mechanism for spontaneous R-parity breaking in a class of extensions of the minimal supersymmetric standard model with an extra Abelian gauge symmetry which is a linear combination of B-L and weak hypercharge. Both U(1)_X and R-parity are broken by the vacuum expectation value of the right-handed sneutrinos which is proportional to the soft SUSY masses. In these models the mechanism for spontaneous R-parity violation can be realized even with positive soft masses. In this context one has a realistic mechanism for generating neutrino masses as well as a realistic spectrum. We briefly discuss the possible collider signals which could be used to test the theory, the contributions for proton decay and the possibility of a gravitino as a dark matter candidate.

description: We report plane-polarized Raman scattering spectra of iron oxypnictide superconductor NdFeAsO$_{1-x}$F$_x$ single crystals with varying fluorine $x$ content. The spectra exhibit sharp and symmetrical phonon lines with a weak dependence on fluorine doping $x$. The temperature dependence does not show any phonon anomaly at the superconducting transition. The Fe related phonon intensity shows a strong resonant enhancement below 2 eV. We associate the resonant enhancement to the presence of an interband transition around 2 eV observed in optical conductivity. Our results point to a rather weak coupling between Raman-active phonons and electronic excitations in iron oxypnictides superconductors.

description: Particle production in high-energy collisions is often addressed within the framework of the thermal (statistical) model. We present a method to calculate the canonical partition function for the hadron resonance gas with exact conservation of the baryon number, strangeness, electric charge, charmness and bottomness. We derive an analytical expression for the partition function which is represented as series of Bessel functions. Our results can be used directly to analyze particle production yields in elementary and in heavy ion collisions. We also quantify the importance of quantum statistics in the calculations of the light particle multiplicities in the canonical thermal model of the hadron resonance gas.

description: Privacy preserving association rule mining has triggered the development of many privacy preserving data mining techniques. A large fraction of them use randomized data distortion techniques to mask the data for preserving. This paper proposes a new transaction randomization method which is a combination of the fake transaction randomization method and a new per transaction randomization method. This method distorts the items within each transaction and ensures a higher level of data privacy in comparison to the previous approaches. The pertransaction randomization method involves a randomization function to replace the item by a random number guarantying privacy within the transaction also. A tool has also been developed to implement the proposed approach to mine frequent itemsets and association rules from the data guaranteeing the antimonotonic property.

description: Aims. We use the IBIS/ISGRI telescope on-board INTEGRAL to measure the position of the centroid of the 20-200 keV emission from the Crab region. Methods. We find that the astrometry of the IBIS telescope is affected by the temperature of the IBIS mask during the observation. After correcting for this effect, we show that the systematic errors in the astrometry of the telescope are of the order of 0.5 arcsec. In the case of the Crab nebula and several other bright sources, the very large number of photons renders the level of statistical uncertainty in the centroid smaller or comparable to this value. Results. We find that the centroid of the Crab nebula in hard X-rays (20-40 keV) is shifted by 8.0 arcsec with respect to the Crab pulsar in the direction of the X-ray centroid of the nebula. A similar shift is also found at higher energies (40-100 and 100-200 keV). We observe a trend of decreasing shift with energy, which can be explained by an increase in the pulsed fraction. To differentiate between the contribution of the pulsar and the nebula, we divide our data into an on-pulse and off-pulse sample. Surprisingly, the nebular emission (i.e., off-pulse) is located significantly away from the X-ray centroid of the nebula. Conclusions. In all 3 energy bands (20-40, 40-100, and 100-200 keV), we find that the centroid of the nebula is significantly offset from the predicted position. We interpret this shift in terms of a cut-off in the electron spectrum in the outer regions of the nebula, which is probably the origin of the observed spectral break around 100 keV. From a simple spherically-symmetric model for the nebula, we estimate that the electrons in the external regions of the torus (d ~ 0.35 pc from the pulsar) reach a maximal energy slightly below 10^14 eV.

Adjustment and intervention needs in young carers of people with chronic illnesses or disability : a systematic review
Creators: name: S Maniam, SV
Publisher: name: University Of Tasmania
Year: 2023

description: The need for informal carers has significantly grown, and continues to grow, with young people under the age of 25 years taking on the carer role for people (usually family members) with chronic illnesses. On average young carers can provide up to 20 hours of various physically and emotionally demanding duties per week. This provision of care is often associated with psychological distress and an increased risk of having a chronic illness themselves. This reduces their capacity to manage their own needs and provide quality care to a chronically ill person. Young carers who are not adequately supported with appropriate psychosocial intervention represent an especially vulnerable population with developmental concerns particularly faced by adolescents. This systematic review identified and evaluated quantitative research, focusing on the outcome of psychosocial interventions on young carers of people with chronic illnesses. CINAHL via EBSCO, EMBASE via OVID, Medline via OVID, PsychINFO via OVID, PubMed, Scopus and Web of Science were the selected and searched databases. Unpublished/grey literature was noted in Scopus and the World Health Organisation database. The systematic search revealed that only 4 studies met the inclusion criteria to be included in this review. Assessment of scientific rigour and risk of bias revealed methodological limitations of the included studies and results indicate minimal intervention efficacy. This review emphasises the need for gaining further quantitative evidence on the efficacy of psychosocial interventions for young carers. Furthermore, there is a need to develop standardised protocols for age-appropriate interventions designed to promote psychosocial adjustment among young carers and assist in the development of governmental policies to better support these vulnerable individuals take better care of people with chronic illness.

description: Since about ten years ago, varying $α$ theories attracted many attentions, mainly due to the first observational evidence from the quasar absorption spectra that the fine structure ``constant'' might change with cosmological time. In this work, we investigate the cosmic evolution of $α$ driven by the Dirac-Born-Infeld (DBI) scalar field. To be general, we consider various couplings between the DBI scalar field and the electromagnetic field. We also confront the resulting $Δα/α$ with the observational constraints, and find that various cosmological evolution histories of $Δα/α$ are allowed. Comparing with the case of varying $α$ driven by quintessence, the corresponding constraints on the parameters of coupling have been relaxed, thanks to the relativistic correction of the DBI scalar field.

description: The fluorination of the peri-substituted acenaphthyl scaffolds 5-PhE-Ace-6-PPh2 (1E, E=O, S, Se, Te) using XeF2 afforded the difluorinated products 5-PhE-Ace-6-PF2Ph2 (2E, E=O, S, Se, Te) and tetrafluorinated products 5-PhEF2-Ace-6-PF2Ph2 (3E, E=Se, Te) depending on the stoichiometry applied. Fluoride abstraction of 2E using Me3SiOTf gave rise to the chalcogenide supported fluorophosphonium ions [5-PhE-Ace-6-P(F)Ph2](OTf) (4O and 5E, E=S, Se, Te). The molecular structure of 4O features a tetrahedral P atom, whereas those of the heavier analogues (5E, E=S, Se) contain trigonal bipyramidal P atoms that arise from intramolecular LP(E)→σ*(P−F) interactions.
Exploring local government approaches to sustainable practice : an investigation into tourism's development in Tasmania
Creators: name: May, BM
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis has addressed a gap in the literature regarding perceptions among local government in the Australian State of Tasmania towards tourism and its integration with sustainable practise. The United Nations World Tourism Organisation (UNWTO, 2008) has advocated implementing the concept of sustainable tourism at destination levels in mitigation of the negative externalities acknowledged to precipitate socio-cultural and environmental change in local communities where tourism influxes proliferated (Helbling, 2010). But the exclusivity of neo-liberal progrowth tourism policy agendas evident at National and State Government levels may have overlooked a duty of care regarding the effects of tourism influxes and prompted questions in respect of the consequences from increased demand generation and the ensuing commodification of both community and environment (Tribe, 2008; Bramwell and Lane, 2011; Buckley, 2012). Australia has since discontinued membership of the UNWTO and dialogue regarding the integration of sustainability and care of the tourism product has appeared disproportionate to the importance placed on maximising its economic contribution. This study has explored grounds for suggesting that tourism policies in Tasmania, by pursuing short-term agendas to maximise tourism's economic contribution, may have overlooked the associated longer term social and environmental risks were the resource base on which tourism is dependent is rendered unsustainable. Relative to other Australian States the greater importance placed on tourism's contribution to Tasmania's economy when coupled to the high touristic value bestowed on the State's pristine topography (Government of Tasmania, 2013a), has argued strongly for its effective management as a sustainable resource in accord with UNWTO advocacy. The research question asked - to what extent are the UNWTO principles of sustainable tourism evident in the policies and planning practices of Tasmanian local government? A two-phase inductive research design was applied comprising a content analysis of council planning documents and interviews with local government employees. Collectively, these interrogated the local status of tourism in Tasmania and whether stakeholders from within, but also outside the State's tourism industry, acted to progress or resist the integration of sustainable tourism. Rational choice theory was used to explore the differing responses of industry and governments (Burns, 1972; Scott, 2000, Boudon, 2009). The study determined that governmental arrangements regarding tourism's management in Tasmania have acted to blunt its competitive edge, its amenability to the integration of sustainable tourism, and exposed the socio-cultural and environmental integrity of its communities to long-term risk.

description: The pentafluoroorthotellurate group (−OTeF5, teflate) exhibits high electron-withdrawing properties. Indeed, it is often used as a bulky substitute for fluoride due to its high chemical stability and larger size, which reduces its tendency to act as a bridging ligand. These characteristics make it a valuable ligand in synthetic chemistry, facilitating the preparation of molecular structures analogous to polymeric fluoride-based compounds. In this study, we explore the electronic structure of the teflate group by using advanced Quantum Chemical Topology (QCT) methods to better understand its bonding nature and compare its group electronegativity with that of the halogens. For that, we examine XOTeF5 systems (X = F, Cl, Br, I) and decompose X–OTeF5 interactions into classical (ionic) and exchange-correlation (covalent) contributions by using interacting quantum atoms (IQA) energy decomposition scheme. We also conduct a detailed analysis of electron distribution by utilizing the statistical framework of electron distribution functions (EDFs) and examine the electron localization function (ELF), electron density, and reduced density gradient scalar functions, as well as delocalization indices and QTAIM charges. The results show that the electron-withdrawing properties of the teflate group are comparable to those of fluorine, albeit slightly lower. Moreover, its internal bonding is primarily ionic. Additionally, we compare −OTeF5 with other O-donor groups, demonstrating that the electron-withdrawing properties within OEF5 (E = S, Se, Te) systems are nearly identical, and these groups show a higher group electronegativity than OCF3, OC(CF3)3, and OC6F5.

description: We report comprehensive resistivity measurements of single crystalline samples of the Ba(Fe(1-x)Co(x))2As2 high Tc superconductor under hydrostatic pressure up to 2.75 GPa and over a broad concentration range, 0 < x < 0.099. We show that application of pressure progressively suppresses the SDW transition temperature, T_SDW, in the underdoped regime. There is no sign of pressure-induced superconductivity in the undoped BaFe2As2 down to 1.8 K, but applied pressure dramatically enhances Tc in the underdoped regime. The effect of pressure on Tc is very small in the optimally and overdoped regimes. As a consequence, the dome of the superconducting phase extends to x 0.02 under pressure. We discuss the implications of our findings in the context of a possible quantum phase transition between the SDW and superconducting phases.

description: The environmental problems that our modern global civilization is facing are on a magnitude that has never been seen before in the annals of human history. As a direct consequence of these problems, both the mental and physical well-being of the current generation, as well as the generations who will come after them in the foreseeable future, are placed in a precarious position. The most important component in the progression of climate change is the release of greenhouse gases into the atmosphere, which occurs as a direct result of the activities of humans. As a direct result of climate change caused by humans, temperatures will continue to rise, more extreme weather will become more regular, and sea levels will continue to grow. As a result of activities such as overfishing, cutting down forests, and using up sources of energy that aren't renewable, the value of the natural capital that currently exists on Earth is deteriorating at an alarming rate. All of these activities have the effect of diminishing the amount of natural resources available, and as a result, the value of the natural capital that currently exists. As a consequence, this leads to the contamination of ecosystems and has a negative impact on human health. Agricultural practises, industrial activity, and the dumping of garbage are only few of the factors that contribute to pollution. Pollution is caused by a variety of factors, including those listed above, which are among those that contribute to pollution.

description: The Next Generation Wireless Networks (NGWN) will be heterogeneous in nature where the different Radio Access Technologies (RATs) operate together .The mobile terminals operating in this heterogeneous environment will have different QoS requirements to be handled by the system. These QoS requirements are determined by a set of QoS parameters. The radio resource management is one of the key challenges in NGWN. Call admission control is one of the radio resource management technique plays instrumental role in ensure the desired QoS to the users working on different applications which have diversified QoS requirements from the wireless networks . The call blocking probability is one such QoS parameter for the wireless network. For better QoS it is desirable to reduce the call blocking probability. In this customary scenario it is highly desirable to obtain analytic Performance model. In this paper we propose a higher order Markov chain based performance model for call admission control in a heterogeneous wireless network environment. In the proposed algorithm we have considered three classes of traffic having different QoS requirements and we have considered the heterogeneous network environment which includes the RATs that can effectively handle applications like voice calls, Web browsing and file transfer applications which are with varied QoS parameters. The paper presents the call blocking probabilities for all the three types of traffic both for fixed and varied traffic scenario.

description: Purpose: A survey of audiologists’ diagnosis and intervention protocols for auditory processing disorder (APD) was conducted to determine current protocols and compare results with published recommendations.Method: A survey was distributed by mail to 515 American Speech-Language-Hearing Association audiology members who listed APD as an area of expertise and via e-mail to Educational Audiology Association members. The survey was completed by 195 audiologists.Results: The majority of respondents reported using auditory processing (AP) test batteries selected based on clinical experience, review of the literature, and attendance at professional conferences. The most popular tests were dichotic, monaural low-redundancy speech, and temporal processing tests. Treatment and management recommendations were usually customized for each patient based on deficits found in behavioral AP testing. The majority of respondents indicated that audiologists are responsible for APD diagnosis (97%) and recommendation of treatment/management (81%); in contrast, only 40% of respondents indicated audiologists were responsible for providing treatment /management.Conclusions: Audiologists are selecting AP test batteries based on the age and case history of the patient, which is in accordance with recent national guidelines. Audiologists are primarily responsible for APD diagnosis and recommending treatment/management. APD treatment is provided by speech-language pathologists, educators, and audiologists.

description: The atmospheric concentration of carbon dioxide (CO2) is of a great interest for scientists since the largest contribution to Earth total radiative forcing is caused by the increase in the atmospheric concentration of CO2 since 1750 (IPCC 2013). Indeed, from 1750 to 2011, anthropogenic CO2 emissions have released 555 gigatons of carbon (GtC) that accumulated within different ecosystems and mainly in the atmosphere (240 GtC), 160 GtC have accumulated in natural terrestrial ecosystems and 155 GtC have been taken up by the ocean (IPCC 2013). Two processes lead to the transfer of CO2 from the atmosphere to the ocean: the physical and the biological carbon pumps (Fig. I.1). First, the physical carbon pump is initialized by the surface ocean, which constantly exchanges gases and heat with the low atmosphere. The solubility of CO2 in seawater increases when temperatures decrease. Thus, in the high latitudes, low temperatures, strong winds, and waves favour the transfer of CO2 into the ocean. Then, CO2 is exported beneath the ocean surface via the sinking of the cold CO2-rich waters. This physical removal of CO2 is also called the solubility pump‚ÄövÑvp. When these cold waters return to the surface ocean and warm up again, they release CO2 to the atmosphere. Secondly, the organic biological carbon pump is initialized in the surface ocean by phytoplankton, which assimilates carbon (C) via photosynthesis, converting CO2 and water in organic matter and oxygen (Fig. I.1). This process removes aqueous CO2 from the euphotic layer, where light penetrates sea surface, and leads to the storage of around 20% of the surface C inventory in the ocean interior (Laws et al., 2000; Falkowski, 2002). In addition, C can also be fixed by corals, foraminifera, coccolithophore or mollusk and crustacean as calcium carbonate to form protective coating or shells, however, this process is counter balanced by the production of carbonic acid, which increase the concentration of CO2 in seawater initiating a diffusive flux of CO2 from the ocean to the atmosphere, the so called carbonate counter pump. These are the reasons why the biological pump of C is a key regulator of the global C cycle. In its absence, atmospheric CO2 concentration would increase by approximately 50 % (200 ppmv), a considerable fraction compared to the present ~ 400 ppmv (Falkowski, 2002).

description: Umbral dots (UDs) were observed in a stable sunspot in NOAA 10944 by the Hinode Solar Optical Telescope on 2007 March 1. The observation program consisted of blue continuum images and spectropolarimetric profiles of Fe I 630 nm line. An automatic detection algorithm for UDs was applied to the 2-hour continuous blue continuum images, and using the obtained data, the lifetime, size, and proper motion of UDs were calculated. The magnetic structure of the sunspot was derived through the inversion of the spectropolarimetric profiles. We calculated the correlations between UD's parameters (size, lifetime, occurrence rate, proper motion) and magnetic fields (field strength, inclination, azimuth), and obtained the following results: (1) Both the lifetime and size of UDs are almost constant regardless of the magnetic field strength at their emergence site. (2) The speed of UDs increases as the field inclination angle at their emergence site gets larger. (3) The direction of movement of UDs is nearly parallel to the direction of the horizontal component of magnetic field in the region with strongly inclined field, while UDs in the region with weakly inclined field show virtually no proper motion. Our results describe the basic properties of magnetoconvection in sunspots. We will discuss our results in comparison to recent MHD simulations by Schussler & Vogler (2006) and Rempel et al. (2009).

description: The Householder reduction of a member of the anti-symmetric Gaussian unitary ensemble gives an anti-symmetric tridiagonal matrix with all independent elements. The random variables permit the introduction of a positive parameter $β$, and the eigenvalue probability density function of the corresponding random matrices can be computed explicitly, as can the distribution of $\{q_i\}$, the first components of the eigenvectors. Three proofs are given. One involves an inductive construction based on bordering of a family of random matrices which are shown to have the same distributions as the anti-symmetric tridiagonal matrices. This proof uses the Dixon-Anderson integral from Selberg integral theory. A second proof involves the explicit computation of the Jacobian for the change of variables between real anti-symmetric tridiagonal matrices, its eigenvalues and $\{q_i\}$. The third proof maps matrices from the anti-symmetric Gaussian $β$-ensemble to those realizing particular examples of the Laguerre $β$-ensemble. In addition to these proofs, we note some simple properties of the shooting eigenvector and associated Prüfer phases of the random matrices.

description: We performed an optical/infrared study of the counterpart of the low-mass X-ray binary KS1731-260 to test its identification and obtain information about the donor. Optical and infrared images of the counterpart of KS1731-260 were taken in two different epochs (2001 and 2007) after the source returned to quiescence in X-rays. We compared those observations with obtained when KS 1731-260 was still active. We confirm the identification of KS1731-260 with the previously proposed counterpart and improve its position to RA=17:34:13.46 and DEC=-26:05:18.60. The H-band magnitude of this candidate showed a decline of ~1.7 mags from outburst to quiescence. In 2007 April we obtained R=22.8+-0.1 and I=20.9+-0.1 for KS1731-260. Similar optical brightness was measured in June 2001 and July 2007. The intrinsic optical color R-I is consistent with spectral types from F to G for the secondary although there is a large excess over that from the secondary at the infrared wavelengths. This may be due to emission from the cooler outer regions of the accretion disk. We cannot rule out a brown dwarf as a donor star, although it would require that the distance to the source is significantly lower than the 7 kpc reported by Muno et al. 2000.

description: A fundamental question in cometary science is whether the different dynamical classes of comets have different chemical compositions, which would reflect different initial conditions. From the ground or Earth orbit, radio and infrared spectroscopic observations of a now significant sample of comets indeed reveal deep differences in the relative abundances of cometary ices. However, no obvious correlation with dynamical classes is found. Further results come, or are expected, from space exploration. Such investigations, by nature limited to a small number of objects, are unfortunately focussed on short-period comets (mainly Jupiter-family). But these in situ studies provide "ground truth" for remote sensing. We discuss the chemical differences in comets from our database of spectroscopic radio observations, which has been recently enriched by several Jupiter-family and Halley-type comets.

description: Purpose: This study compared clinical features, predisposing factors, and concomitant diseases between sporadic and familial Ménière’s disease (MD).Method: Retrospective chart review and postal questionnaire were used. Participants were 250 definite patients with MD (sporadic, n = 149; familial, n = 101) who fulfilled the American Academy of Otorhinolaryngology–Head and Neck Surgery (1995) criteria.Results: On average, familial patients were affected 5.6 years earlier than sporadic patients, and they suffered from significantly longer spells of vertigo (p = .007). The prevalence of rheumatoid arthritis (p = .002) and other autoimmune diseases (p = .046) was higher among the familial patients, who also had more migraine (p = .036) and hearing impairment (p = .002) in their families.Conclusion: The clinical features of familial and sporadic MD are very similar in general, but some differences do exist. Familial MD patients are affected earlier and suffer from longer spells of vertigo.
