An uncertain state : the legality and consequence of Kosovo's declaration of independence under international law
Creators: name: Jenkins, JB
Publisher: name: University Of Tasmania
Year: 2023

description: On the 17 February 2008, Kosovo's Provisional Institutions of Self-Government unilaterally declared their independence from Serbia and, since this time, a significant number of the worlds existing states have conferred recognition upon it. Serbia and its allies ardently contest its legality, however; reaffirming their right to territorial integrity and, as such, their continued sovereignty over the territory that is so often said, by the citizens of it, to be the 'heartland' of their country. The Kosovar Albanians, on the other hand, assert their right to self-determination, and the concomitant 'freedom' that it offers them from a regime at whose hands they have suffered ‚Äö- in recent decades in particular ‚Äö- abuses of immeasurable gravity. This thesis submits that the nascent state of Kosovo satisfies the general requirements of statehood, as set out in the Montevideo Convention on the Rights and Duties of States (1933) ‚Äö- especially in light of the leniency with which borderline cases are so often assessed ‚Äö- and, also, that independence was not precluded under the provisions of United Nations Security Council Resolution 1244.1 As such, and although the resolution did not itself confer a right to independence upon the people of Kosovo, it remained an alternative available to them to the extent that it was also available under the framework of international law in the more general sense. On this front, this thesis endorses the legality of Kosovo's declaration of independence, and third states subsequent recognition of it, in accordance with what is commonly referred to as a 'remedial right' to secession. This right, it is submitted, allows those 'people' that have suffered 'grievous wrongs at the hands of the parent State from which it wishes to secede' ‚Äö- including the denial of their right to internal self-determination, and/or serious and widespread violations of their fundamental human rights ‚Äö- to break away, as a 'last resort' and in the absence of any further, realistic and effective remedies for the peaceful settlement of the conflict.

description: Sepsis and septic shock exhibit a rapid course and a high fatality rate. Antibiotic treatment is time-critical and precise knowledge of the antibiotic concentration during the patients’ treatment would allow individual dose adaption. Over- and underdosing will increase the antimicrobial efficacy and reduce toxicity. We demonstrated that fiber enhanced Raman spectroscopy (FERS) can be used to detect very low concentrations of ciprofloxacin in clinically relevant doses, down to 1.5 µM. Fiber enhancement was achieved in bandgap shifted photonic crystal fibers. The high linearity between the Raman signals and the drug concentrations allows a robust calibration for drug quantification. The needed sample volume was very low (0.58 µL) and an acquisition time of 30 s allowed the rapid monitoring of ciprofloxacin levels in a less invasive way than conventional techniques. These results demonstrate that FERS has a high potential for clinical in-situ monitoring of ciprofloxacin levels.

description: In two recent papers, arXiv:0909.1559 and arXiv:0911.4122, it has been demonstrated that one can obtain quantum corrected Boltzmann kinetic equations for leptogenesis using a top-down approach based on the Schwinger-Keldysh/Kadanoff-Baym formalism. These "Boltzmann-like" equations are similar to the ones obtained in the conventional bottom-up approach but differ in important details. In particular there is a discrepancy between the CP-violating parameter obtained in the first-principle derivation and in the framework of thermal field theory. Here we demonstrate that the two approaches can be reconciled if causal n-point functions are used in the thermal field theory approach. The new result for the medium correction to the CP-violating parameter is qualitatively different from the conventional one. The analogy to a toy model considered earlier enables us to write down consistent quantum corrected Boltzmann equations for thermal leptogenesis in the Standard Model (supplemented by three right-handed neutrinos) which include quantum statistical terms and medium corrected expressions for the CP-violating parameter.

Combined free and forced convection in a horizontal tube under uniform heat flux
Creators: name: Kupper, Arthur K.
Publisher: name: University of British Columbia
Year: 2011

description: This thesis presents experimental results of combined free aid forced convection laminar heat transfer for water flowing through a circular horizontal tube with uniform wall heat flux. The Reynolds number ranged from 100 to 2000, and changes in heat transfer rate allowed a variation, of Grashof number from 300 to 30,000. The Prandtl number ranged from 4 to 9. The effect of secondary flow created by free convection occurring at higher Grashof number indicates an increase in Nusselt number up to 200 per cent. For the fully-developed region two tentative correlations are given. The expression Nu = 48/11 + 0.047 Pr¹′³(Re Ra)¹′⁵correlates 53 per cent of the data to within ± 10 per cent. Another slightly more accurate expression which correlates 68 per cent of the data to within ± 10 per cent, but does not satisfy the pure forced convection, is Nu = 2.41 + 0.082 Pr¹′³ (Re Ra)¹′⁵.

description: In the pipe manufacturing and pipe processing industry, the demand for cost-effective pipes with high strength and good ductility is increasing. In the present study, the inductive longitudinal welding process was combined with a Quenching and Partitioning (Q&P) treatment to manufacture pipes with enhanced mechanical properties. The aim of the Q&P process is to establish a martensitic structure with increased retained austenite content. This allows for the beneficial use of both phases: the strength of martensite as well as the ductility of retained austenite. A 42SiCr steel, developed for Q&P processes, was joined at the longitudinal seam by a high-frequency induction (HFI) welding process and was subsequently heat-treated. The applied heat treatments included normalizing, austenitizing, quenching, and two Q&P strategies (Q&P-A/Q&P-B) with distinct quenching (Tq = 200/150◦ C) and partitioning temperatures (Tp = 300/250◦ C). Investigations of the microstructures revealed that Q&P tubes exhibit increased amounts of retained austenite in the martensitic matrix. Differences between the weld junction and the base material occurred, especially regarding the morphology of the martensite; the martensite found in the weld junction is finer and corresponds more to the lath-type morphology, compared to the base material in the circumference. In all zones of the welded tube circumference, retained austenite has been found in similar distributions. The mechanical testing of the individual tubes demonstrated that the Q&P treatments offer increased strength compared to all other states and significantly improved ductility compared to the quenched condition. Therefore, the approach of Q&P treatment of HFI-welded tubes represents a route for the mass production of high-strength tubular products with improved ductility.

We make use of the freedom of design that quantum corrals provide and show that quantum mechanical objects can be hidden inside the corral, with respect to inelastic electron scattering spectroscopy in combination with scanning tunneling microscopy, and we propose a design strategy. A simple illustration of the invisibility is given in terms of an elliptic quantum corral containing a molecule, with a local vibrational mode, at one of the foci. Our work has implications to quantum information technology and presents new tools for nonlocal quantum detection and distinguishing between different molecules.

Effect of captan on pollen germination and fruit set in strawberry
Creators: name: Chen, Liang-Ing
Publisher: name: University of British Columbia
Year: 2011

description: Using strawberry as a test plant, captan has been shown to inhibit pollen germination when included in or sprayed on the germination medium, or when sprayed on anthers after pollen dehiscence. Toxic effects did not disappear during prolonged germination. However, pollen germination was slightly affected by captan sprayed on the undehisced anthers. When open flowers were sprayed before anther dehiscence, berry set was reduced in the variety Siletz but not in the variety Northwest. When sprayed after anther dehiscence, achene set, and berry development were decreased. The proportion of mishappen fruits increased with captan concentration. Pollination from sprayed anthers was not as effective in fruit setting as control pollination of sprayed pistils. Sprays applied to pistils either just before or just after pollination decreased fruit set. Fruit set was not affected by sprays one day after pollination. Captan therefore seemed to act directly upon pollen germination and not upon the receptivity of the stigma or upon pollen tube growth in the style or upon fertilization.
Entanglement and the quantum-classical transition
Creators: name: Jacobsen, SH
Publisher: name: University Of Tasmania
Year: 2023

description: The ubiquitous theory of quantum mechanics has sparked many controversial debates about possible interpretations and its place in fundamental physical theory. Perhaps most sustained of all the questions is the quest for a complete explanation of the process behind the reduction from quantum to classical phenomena. This thesis shall examine this question through detailed investigation of specific models. The models include a careful exposition of quantum entanglement through the original EPR thought experiment for continuous variables and its mathematical transcription. The transcription is compared with existing methods from quantum optics for achieving experimentally verifiable Bell-type inequality violations, which are commonly interpreted as violations of locality. In further development of this famous paradox, the mathematical model is extended to tripartite continuous variable states, and detailed measures of their violation of locality are presented. Having carefully examined quantum phenomena by the EPR-paradox and its extension to tripartite cases, the investigation proceeds by considering the effect on quantum systems by an environment. This involves a re-examination of some well-known quantum system environment models: the spin-1/2 Spin-Boson and Kondo models, in which a two-level quantum system interacts with a bath of bosons or fermions respectively. The technicalities of the interactions are exposed in intricate detail, with a careful description of the constructive bosonisation and transformation methods involved. The thorough analysis leads to a new observation about the elliptic, or fully anisotropic, Kondo model. Importantly, the re-examination of the detailed structure of fermion-gas impurity models and their connection to quantum dissipative systems enables a comprehensive extension of the family of models to include in particular a new three-level dissipative system. To underline the importance of this model, it is shown that the model is exactly solvable by admitting a reparametrisation of the scattering matrix in terms of R-matrices which obey the Yang-Baxter equation. The examination of the interaction between the quantum and the classical concludes with an investigation of entanglement criteria in the system environment models discussed. A variational Ansatz for the ground state is used to demonstrate the numerical calculation of entropy expressions for the three-level systems, while the reynman-Hellmann Theorem is used to give inprinciple exact results for the entropy corresponding to the specific three-level model Hamiltonian introduced in this thesis. Throughout we provide several suggestions for further work, procedures for experimental verification and practical application.

description: We propose to use alternative cosmic tracers to measure the dark energy equation of state and the matter content of the Universe [w(z) & Omega_m]. Our proposed method consists of two components: (a) tracing the Hubble relation using HII galaxies which can be detected up to very large redshifts, z~4, as an alternative to supernovae type Ia, and (b) measuring the clustering pattern of X-ray selected AGN at a median redshift of z~1. Each component of the method can in itself provide interesting constraints on the cosmological parameters, especially under our anticipation that we will reduce the corresponding random and systematic errors significantly. However, by joining their likelihood functions we will be able to put stringent cosmological constraints and break the known degeneracies between the dark energy equation of state (whether it is constant or variable) and the matter content of the universe and provide a powerful and alternative route to measure the contribution to the global dynamics and the equation of state of dark energy. A preliminary joint analysis of X-ray selected AGN (based on the largest to-date XMM survey; the 2XMM) and the currently largest SNIa sample (Hicken et al.), using as priors a flat universe and the WMAP5 normalization of the power-spectrum, provides: Omega_m=0.27+-0.02 and w=-0.96+-0.07. Equivalent and consistent results are provided by the joint analysis of X-ray selected AGN clustering and the latest Baryonic Acoustic Oscillation measures, providing: Omega_m=0.27+-0.02 and w=-0.97+-0.04.

Leveraging networks to overcome displacement - Urban internally displaced persons in the Democratic Republic of the Congo

description: In the quest for sustainable solutions to record global displacement, promoting displaced persons’ self-reliance and supporting them alongside host communities in regions of displacement have become buzzwords in global and European policy discussions. But despite such pledges, TRAFIG research in Bukavu, eastern Democratic Republic of the Congo (DRC) finds that internally displaced persons (IDPs) in urban settings are largely ignored and unassisted by the state and international humanitarian and development interventions—and are proactively seeking their own solutions. The lack of institutionalised assistance means that IDPs mostly depend on the solidarity of others to be or become self-reliant. In this context, networks are a particularly important source of support and include assistance with locating housing and finding a job in Bukavu and with maintaining and harvesting crops in communities of origin. However, even with the benefits that these connections can bring, IDPs face serious challenges related to their displacement and contend with multiple types of limbo, making it difficult for many to truly overcome situations of protracted displacement. Findings thus point to the need for policies and practices that support urban IDPs in the DRC by helping them nurture and leverage their networks to unlock opportunities. The Policy Brief comes up with four central findings and recommendations: While networks constitute a significant source of support, for too many IDPs, such assistance is only temporary or insufficient to really overcome displacement. Humanitarian and development initiatives should aim to bolster resilient connections, which include informal (e.g.host families) and formal (e.g. churches and labour associations) networks. Many urban IDPs leverage resources in their home communities to make a living in the city. Development actors should support IDPs’ efforts to maintain ties with their communitiesof origin and safeguard mobility between Bukavu and the surrounding rural regions. Not every IDP has a network—or, for fear of stigmatisation, wants to utilise their network. EU assistance should help urban IDPs strengthen and leverage their networks by reinforcing existing connections and building new ones. Current approaches to forced displacement and access to solutions need to be better equipped to support those strategies. The complex and long-standing nature of displacement in eastern DRC calls for increased attention and assistance from policymakers in Europe and beyond to help IDPs move from temporary to more permanent solutions.

Two transport regimes can be identified which are characterized by a nonzero value of the average velocity of particles and a zero value, respectively. The properties of directed transport in these regimes are investigated both analytically and numerically in terms of a random sawtooth potential and a periodically varying driving force. Precise conditions for the occurrence of transition between these two transport regimes are derived and analyzed in detail.

At the edges ‚Äö- A place and a space for tears: Exploring the framing of depression in contemporary western culture
Creators: name: Collins, HE
Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis I explore the contemporary Western framing of depression as an illness requiring treatment. This understanding of depression is examined through a hermeneutic study of the depression literature, focussing primarily on medical and sociological academic literature, but also including one popular website. Drawing on Weberian social theory, I argue that the dominant cultural understanding of depression allows only one story to be told: that of depression as an illness necessitating medical treatment to facilitate a cure. However, depression can also be understood as part of the suffering that constitutes what it is to be human. While contemporary approaches to depression are valuable, they are also restricted. I suggest an inclusive interstitiality of different stories would expand the current framing of depression. I draw on Weber's analysis of the causal and codified nature of Western rationality and of the total world-view of the secular West deriving from religious antecedents to analyse the current framing of depression. In addition, I employ Derridean concepts of the Western proclivity for logocentrism and Levinasian concepts of the Western impulse to change Other into Same to augment the Weberian analysis to demonstrate how dominant approaches to depression are influenced by both historical and cultural factors 'specific and peculiar' to the Western way of viewing the world. This approach embeds depression within the historical-cultural milieu of the West, which I argue provides a predominantly exclusive and scientifically based view of depression as illness. I demonstrate this through an exploration of historical influences, interpretative positions, the assigning of meaning, and information produced for the public. Finally, I proffer some possibilities for future directions. The meta-perspective provided by this approach facilitates, for example, an appreciation that contemporary medical science inherited its belief in a total worldview from Western religious antecedents. Such a world-view results in the contemporary framing of depression functioning as though depression can only be viewed from the medical-scientific perspective, which is considered, a priori, to be the correct perspective. Establishing this meta-perspective enables the contemporary framing of depression to be situated firmly within its historical-cultural background. Through this re-interpretation of contemporary approaches to depression the study provides another perspective on depression: one that is historically and culturally grounded, one that challenges current perspectives and opinions, and one that encourages respectful dialogue and debate.

description: Time-and-frequency resolved pump-probe optical spectroscopy is used to investigate the effect of the impulsive injection of delocalized excitations through a charge-transfer process in insulating CuGeO3. A large broadening of the charge-transfer edge is observed on the sub-ps timescale. The modification of this spectral feature can not be attributed to the local increase of the effective temperature, as a consequence of the energy absorbed by the pump pulse. The measured modifications of the optical properties of the system are consistent with the creation of a non-thermal state, metastable on the ps timescale, after the pump-induced impulsive modification of the electron interactions.

Herein, we describe a general methodology for such transformations using homogeneous copper-based catalysts in the presence of air. The utility of this novel methodology is demonstrated for Cα−Cβ bond scission in >70 amines with excellent functional group tolerance. This transformation establishes tertiary amines as a general synthon for amides and provides valuable possibilities for their scalable functionalization in, for example, natural products and bioactive molecules. © 2019 The Authors.

Depending on the cation, it was possible to extract salts containing the formal dihydrogen tricyanide [CN(HCN)2]− and trihydrogen tetracyanide ions [CN(HCN)3]− from liquid HCN when a fast crystallization was carried out at low temperatures. X-ray structure elucidation revealed hydrogen-bridged linear [CN(HCN)2]− and Y-shaped [CN(HCN)3]− molecular ions in the crystal. Both anions can be considered members of highly labile cyanide-HCN solvates of the type [CN(HCN)n]− (n=1, 2, 3 …) as well as formal polypseudohalide ions. © 2020 The Authors.

A comparative study of the behaviour of two sympatric species of freshwater sculpins, Cottus asper Richardson and Cottus aleuticus Gilbert, in relation to their differences in microhabitat
Creators: name: Fenwick, Julie M.
Publisher: name: University of British Columbia
Year: 2011

description: The behaviour of two sympatric species of sculpins, Cottus asper and Cottus aleuticus, which occupy different microhabi-tats, was studied by the comparative method. The aim of the study was to determine some of the important behavioural adaptations to the differences in their microhabitats. C. asper occurs in areas of slow current and fine substrate and G. aleuticus in areas of fast current and coarse substrate. The posture, orientation to the current, and locomotary and feeding behaviour of the species were examined in the laboratory under different conditions of current and substrate. C. asper responds to a current by lying flat on the substrate. C. aleuticus also exhibits this posture on sand, but on a gravel substrate, raises the body, by spreading the pectoral fins. C. aleuticus adopts a parallel orientation to the current more frequently than a broadside orientation, but C. asper "prefers" the broadside position. However, both species assume the broadside position more frequently on sand than on gravel, and the parallel orientation more frequently on gravel than on sand. C. asper is a much poorer swimmer than C. aleuticus, especially in a current. C. aleuticus is much more active than C. asper at all times of day and under all conditions of current tested. C. asper is a lurking predator and takes food from the surface of the substrate. C. aleuticus is a more active feeder, and feeds by swimming to the water surface, by taking food from the substrate surface and by foraging in the crevices of the gravel. From laboratory observations it appears that C. aleuticus relies on sight in food detection to a greater extent than does C. asper. The findings of this study were compared with field observations and with previous studies of other cottid species. It was concluded from this that C. aleuticus’ posture, orientation to the current, and locomotory and feeding behaviour are a reflection of a more active way of life and are related to the special problems of life in a strong current. C. asper, however, is typical, both in behaviour and morphology, of bottom-dwelling, sedentary fish, of reclusive habits.

description: This deliverable provides the legal and ethical requirements applicable to ENSURESEC. It is basedon the findings of D1.5. D3.1 takes its starting point in international conventions and EU primary legislation and identifies legal requirements embedded in secondary EU legislation. It also addressespossible futuredevelopments in the legal field. In addition, the framework consists of ethical requirements. The ethical principles are especially important for emerging innovations, such as artificial intelligence. The legal and ethical framework described in detail has also been applied to the ENSURESEC innovative tool. D3.1 lays the basis for the impact assessment to be carried out in WP8 andwhich willresult in D8.5.

description: Ageing in systems without detailed balance is studied in bosonic contact and pair-contact processes with Levy diffusion. In the ageing regime, the dynamical scaling of the two-time correlation function and two-time response function is found and analysed. Exact results for non-equilibrium exponents and scaling functions are derived. The behaviour of the fluctuation-dissipation ratio is analysed. A passage time from the quasi-stationary regime to the ageing regime is defined, in qualitative agreement with kinetic spherical models and p-spin spherical glasses.

Chirality Dependence of the $K$-Momentum Dark Excitons in Carbon Nanotubes

description: Using a collection of twelve semiconducting carbon nanotube samples, each highly enriched in a single chirality, we study the chirality dependence of the $K$-momentum dark singlet exciton using phonon sideband optical spectroscopy. Measurements of bright absorptive and emissive sidebands of this finite momentum exciton identify its energy as 20 - 38 meV above the bright singlet exciton, a separation that exhibits systematic dependencies on tube diameter, $2n+m$ family, and semiconducting type. We present calculations that explain how chiral angle dependence in this energy separation relates to the Coulomb exchange interaction, and elaborate the dominance of the $K_{A_1'}$ phonon sidebands over the zone-center phonon sidebands over a wide range of chiralities. The Kataura plot arising from these data is qualitatively well described by theory, but the energy separation between the sidebands shows a larger chiral dependence than predicted. This latter observation may indicate a larger dispersion for the associated phonon near the $K$ point than expected from finite distance force modeling.

Nuclear fusion in a dense plasma

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: Nuclear Theory (nucl-th)
subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: The standard theory of nuclear fusion rates in a strongly interacting plasma can be (correctly) derived only when the energy release, Q, is large compared to other energies in the problem. We exhibit a result for rates that provides a basis for calculating the finite Q corrections. Crude estimates indicate a significant defect in the conventional results for some regions of high density and strong plasma coupling. We also lay some groundwork for a path integral calculation of the new effects.

subject: 540

description: Core–shell nanocatalysts are attractive due to their versatility and stability. Here, we describe cobalt nanoparticles encapsulated within graphitic shells prepared via the pyrolysis of a cationic poly-ionic liquid (PIL) with a cobalt(II) chloride anion. The resulting material has a core–shell structure that displays excellent activity and selectivity in the self-dehydrogenation and hetero-dehydrogenation of primary amines to their corresponding imines. Furthermore, the catalyst exhibits excellent activity in the synthesis of secondary imines from substrates with various reducible functional groups (C=C, C≡C and C≡N) and amino acid derivatives. © 2020 The Authors.

subject: selectivity
subject: 540

description: For the first time, the monoalkoxycarbonylation of easily available 1,3-diynes to give synthetically useful conjugated enynes has been realized. Key to success was the design and utilization of the new ligand 2,2′-bis(tert-butyl(pyridin-2-yl)phosphanyl)-1,1′-binaphthalene (Neolephos), which permits the palladium-catalyzed selective carbonylation under mild conditions, providing a general preparation of functionalized 1,3-enynes in good-to-high yields with excellent chemoselectivities. Synthetic applications that showcase the possibilities of this novel methodology include an efficient one-pot synthesis of 4-aryl-4H-pyrans as well as the rapid construction of various heterocyclic, bicyclic, and polycyclic compounds. © 2020 The Authors.

description: It is suggested that superfluid helium (condensate of 4-He atoms) may stimulate nuclear alpha-decay in a situation when an alpha-emitter moves through superfluid helium with fine-tuned velocity, so that the backward-emitted alpha-particle is at rest in the laboratory frame. It is shown that the probability of stimulated alpha-decay in this case may be sizable enough to be detected.

Intramolecular fluorescence correlation spectroscopy in a feedback tracking microscope

Publisher: name: arXiv
Year: 2009
Subjects: subject: Optics (physics.optics)

description: We derive the statistics of the signals generated by shape fluctuations of large molecules studied by feedback tracking microscopy. We account for the influence of intramolecular dynamics on the response of the tracking system, and derive a general expression for the fluorescence autocorrelation function that applies when those dynamics are linear. We show that tracking provides enhanced sensitivity to translational diffusion, molecular size, heterogeneity and long time-scale decays in comparison to traditional fluorescence correlation spectroscopy. We demonstrate our approach by using a three-dimensional tracking microscope to study genomic $λ$-phage DNA molecules with various fluorescence label configurations.
