description: We report Quantum Monte Carlo calculations of weak transitions in $A\leq 10$ nuclei, based on the Norfolk two- and three-nucleon chiral interactions, and associated one- and two-body axial currents. We find that the contribution from two-body currents is at the $2$ - $3\%$ level, with the exception of matrix elements entering the rates of $^8$Li, $^8$B, and $^8$He beta decays. These matrix elements are suppressed in impulse approximation based on the (leading order) Gamow Teller transition operator alone; two-body currents provide a $20$ - $30\%$ correction, which is, however, insufficient to bring theory in agreement with experimental data. For the other transitions, the agreement with the data is satisfactory, and the results exhibit a negligible to mild model dependence when different combinations of Norfolk interactions are utilized to construct the nuclear wave functions. We report a complete study of two-body weak transition densities which reveals the expected universal behavior of two-body currents at short distances throughout the range of $A\,$=$\,3$ to $A\,$=$\,10$ systems considered here.

title: IMAGES OF WOMEN IN NOVELS WRITTEN IN ENGLISH BY SOUTH AFRICAN WOMEN
Creators: name: Randall, Mary Stewart
Publisher: name: The Open University
Year: 1991

description: The thesis discusses over a century of novel writing by South African women writers as they respond to political change from colonialism to apartheid. It follows the sequence of publica­tion. The first five chapters describe the work of Olive Schreiner, Sarah Gertrude Millin, Pauline Smith, Nadine Gordimer and other white writers; the last two chapters are on Bessie Head and other black writers. The thesis briefly examines problems of writing and publication, and the reasons why some writers choose or are forced to live abroad. Many novels are autobiographical, and many writers interpret the South African situation didactically for their readers in the West and South Africa. Most of the novels are written within the European realist tradition: exceptions like A Question of Power stress the importance of the inner life in bringing about personal and political change. The thesis examines the ways in which the writers use imagery, particularly from nature, to suggest changes in women's lives and even help to create myths. The novels reflect the divisions in the society: perhaps only Bessie Head and Phyllis Altman cross them successfully. The novels indicate how misuse of power by men can change the lives and characters of women, although white women's lives still rest on black labour. Although white bourgeois women increasingly insist on choosing the direction of their lives, becoming less dependent on personal relationships, the novels illustrate how rarely even educated black women can choose how to live. The break-up of families is a recurring theme, as is the isolation and fear of women. However, hope for the future lies in the creation of male characters with feminist sympa­thies, such as Waldo and Pholoso. In such ways the writers themselves become part of the process of change in South Africa.

description: The aim of this dissertation is to frame the liability of the parties involved in a joint credit account, who are also partners in business partnerships. Initially, the contract of the joint credit account, its aim, its basic principles and its results were described, while there was also reference to loan contracts in conjunction with the joint credit account as well as the collateral and the deposit that can be offered at the time of the agreement. Furthermore, the various types of partnerships were analyzed, as well as the partners’ liability for the company’s debts at the time of their entrance to the company, for as long as they were a part of it, but also following their exit from it. Finally, the partners’ liability for each type of partnership was presented, concerning the money that still remains after the joint credit account is closed, both in cases that they contracted as debtors and in cases that they contracted as guarantors

description: High-fidelity manipulation is the key for the physical realization of fault-tolerant quantum computation. Here, we present a protocol to realize universal nonadiabatic geometric gates for silicon-based spin qubits. We find that the advantage of geometric gates over dynamical gates depends crucially on the evolution loop for the construction of the geometric phase. Under appropriate evolution loops, both the geometric single-qubit gates and the CNOT gate can outperform their dynamical counterparts for both systematic and detuning noises. We also perform randomized benchmarking using noise amplitudes consistent with experiments in silicon. For the static noise model, the averaged fidelities of geometric gates are around 99.90\% or above, while for the time-dependent $1/f$-type noise, the fidelities are around 99.98\% when only the detuning noise is present. We also show that the improvement in fidelities of the geometric gates over dynamical ones typically increases with the exponent $α$ of the $1/f$ noise, and the ratio can be as high as 4 when $α\approx 3$. Our results suggest that geometric gates with judiciously chosen evolution loops can be a powerful way to realize high-fidelity quantum gates.

Nurses' intentions and behaviors regarding organ donation : a scoping review
Creators: name: Butler, Heidi Elizabeth
Publisher: name: The University of British Columbia
Year: 2017

description: BACKGROUND: Solid organ transplant can drastically improve quality of life and extend life expectancy. In Canada and around the world, the demand for organs well exceeds the available supply. Nurses in critical care areas play an important role in identifying and managing donors. Efforts have been made to improve donation rates in Canada, however, recent reviews of donor potential have revealed many missed opportunities linked to healthcare provider behaviours. AIMS: The Theory of Planned Behaviour (TPB) has been utilized to help explain and improve various health behaviours. A scoping review of the literature guided by the TPB was conducted exploring nurses’ attitudes, perceived behavioural control and social norms around donation. Applying the TPB model, I considered how these factors may influence nurses’ willingness to identify potential donors, speak with families and participate in donor management. SEARCH STRATEGY: Two databases CINAHL and PubMed were searched to identify 17 relevant articles included in the scoping review. Studies included were focused on nurses and organ donation, and at least one element of the TPB: attitudes, knowledge/perceived behavioural control and/or social norms in relation to organ donation. FINDINGS: The scoping review revealed nurses had mostly positive attitudes towards organ donation. However, the nurses in the studies reviewed felt they lacked knowledge around the concept of brain death, donor legality and the donor process. Nurses also lacked confidence and skills in initiating conversations regarding donation with families. They also recognized a need for more and continued education regarding organ donation. Nurses in one of the studies perceived there to be a lack of organizational structures and guidelines in place to help support donation. CONCLUSION: Applying the TPB model to the findings, one can infer that nurses’ attitudes, perceived behavioural control and social norms related to organ donation affect their intentions and behaviours of referring potential donors and approaching families. Addressing the barriers that exist for nurses participating in the donation process should be examined in order to maximize the capacity of nurses working in critical care areas. RELEVANCE TO NURSING PRACTICE: Nurses are seen as an essential link in organ procurement and play an important role in addressing the organ shortage in Canada by simply identifying potential donors and supporting families through the process. Incorporating more and frequent education and training in hospital and in classroom could help to improve nurses’ capacity to participate in the organ donor process, address negative attitudes and unpack ethically challenging or morally distressing cases.

Σκοπός της παρούσας διπλωματικής εργασίας ήταν η ανάπτυξη μιας μεθόδου για την εκτίμηση της αντιοξειδωτικής δράσης του παρθένου ελαιολάδου ως έχει, η οποία θα παρέχει αποτελέσματα σε σύντομο χρονικό διάστημα, καθιστώντας παράλληλα δυνατή την ανάλυση πλήθους δειγμάτων με μείωση της κατανάλωσης των αντιδραστηρίων και την καλύτερη αξιοποίηση του προσωπικού του Εργαστηρίου. Για τον λόγο αυτό έγινε μετατροπή της in situ χρωματομετρικής δοκιμής δέσμευσης της DPPH● σε on-line σύστημα αντίδρασης τύπου FIA (flowinjectionanalysis) που θα εφαρμόζονταν στο παρθένο ελαιόλαδο ως έχει.

Στη συνέχεια, η μέθοδος εφαρμόστηκε σε σειρά δειγμάτων παρθένου ελαιολάδου (φρέσκων ή αποθηκευμένων στο σκοτάδι έως 18 μήνες στους 20 oC) που ήταν χαρακτηρισμένα ως προς της σύστασή τους σε επιμέρους φαινολικές ενώσεις (ολική υδροξυτυροσόλη και α-τοκοφερόλη) για τον έλεγχο της διαγνωστικής της αξίας
description: The antioxidant activity of virgin olive oil is an important parameter associated with oil’s nutritional value and oxidative stability, characteristics that determine its quality. This thesis aimed to develop a method for the estimation of the antioxidant activity of untreated virgin olive oilin a short period, making, thus, feasible the analysis of many samples with reduced reagent consumption and less staff occupation. For this purpose, the in-situ colorimetric DPPH● assay was adapted into an online FIA (Flow Injection Analysis) type reaction system which would be applied for the analysis of intact virgin olive oil. During the process, critical analytical parameters examined were the reaction solvent, the concentration of the DPPH● solution, and the flow of its delivery.Τhe method performance was examined in terms of repeatability, linearity, the limit of detection (LOD), and quantification (LOQ), as well as its sensitivity and selectivity. Then, the method was applied to a set of virgin olive oil samples (fresh or stored in the dark at 20 oC for up to 18 moths) already characterized for their content in phenolic compounds (total hydroxytyrosol and α-tocopherol) to examine its diagnostic potential

description: A proximity focusing ring imaging Cherenkov detector using aerogel as the radiator has been studied for an upgrade of the Belle detector at the KEK-B-factory. We constructed a prototype Cherenkov counter using a 4 x 4 array of 64-channel flat-panel multi-anode PMTs (Hamamatsu H8500) with a large effective area. The aerogel samples were made with a new technique to obtain a higher transmission length at a high refractive index (n=1.05). Multi-channel PMTs are read-out with analog memory chips. The detector was tested at the KEK-PS pi2 beam line in November, 2002. To evaluate systematically the performance of the detector, tests were carried out with various aerogel samples using pion beams with momenta between 0.5 GeV/c and 4 GeV/c. The typical angular resolution was around 14 mrad, and the average number of detected photoelectrons was around 6. We expect that pions and kaons can be separated at a 4 sigma level at 4 GeV/c.

description: The present systematic review aimed to investigate the potential benefit of topical application of hyaluronic acid as an adjunct to periodontal treatment. A total of 19 electronic databases were thoroughly searched and the appropriate studies were identified with the use of specific eligibility criteria, according to PRISMA guidelines. Two reviewers independently screened and selected the studies and made the data extraction and the quality assessment, by using the Cochrane risk of bias tool. Totally, 38 randomized clinical trials (8 related to gingivitis therapy, 20 related to non-surgical periodontal therapy and 10 related to surgical periodontal therapy) were finally included in the systematic review. Two studies were reported with low risk of bias in gingivitis group, merely 1 study in non-surgical group and 6 studies in surgical group. The adjunct use of hyaluronan combined to all treatment modalities shows improvement of patients’ postoperative course. However, further research is needed to define the ideal regimen characteristics

description: Three dimensional supersymmetric field theories have large moduli spaces of circular Wilson loops preserving a fixed set of supercharges. We simplify previous constructions of such Wilson loops and amend and clarify their classification. For a generic quiver gauge theory we identify the moduli space as a quotient of $C^m$ for some $m$ by an appropriate symmetry group. These spaces are quiver varieties associated to a cover of the original quiver or a subquiver thereof. This moduli space is generically singular and at the singularities there are large degeneracies of operators which seem different, but whose expectation values and correlation functions with all other gauge invariant operators are identical. The formulation presented here, where the Wilson loops are on $S^3$ or squashed $S^3_b$ also allows to directly implement a localization procedure on these observables, which previously required an indirect cohomological equivalence argument.

description: The center-of-mass dynamics of a vortex in the surface region of a Bose-Einstein condensate is investigated both analytically using a variational calculation and numerically by solving the time-dependent Gross-Pitaevskii equation. We find, in agreement with previous works, that away from the Thomas-Fermi surface, the vortex moves parallel to the surface of the condensate with a constant velocity. We obtain an expression for this velocity in terms of the distance of the vortex core from the Thomas-Fermi surface that fits accurately with the numerical results. We find also that, coupled to its motion parallel to the surface, the vortex oscillates along the direction normal to the surface around a minimum point of an effective potential.

description: We study the dynamics of merging compact binaries near a rotating supermassive black hole (SMBH) in a hierarchical triple configuration. We include various general relativistic effects that couple the inner orbit, the outer orbit and the spin of the SMBH. During the orbital decay due to gravitational radiation, the inner binary can encounter an "apsidal precession resonance" and experience eccentricity excitation. This resonance occurs when the apsidal precession rate of the inner binary matches that of the outer binary, with the precessions driven by both Newtonian interactions and various post-Newtonian effects. The eccentricity excitation requires the outer orbit to have a finite eccentricity, and is most effective for triples with small mutual inclinations, in contrast to the well-studied Lidov-Kozai effect. The resonance and the associated eccentricity growth may occur while the binary emits gravitational waves in the low-frequency band, and may be detectable by future space-based gravitational wave detectors.

description: We derive the finite temperature oscillation modes of a harmonically confined Bose-Einstein condensed gas undergoing rigid body rotation supported by a vortex lattice in the condensate. The hydrodynamic modes separate into two classes corresponding to in-phase (center-of-mass) and counter-phase (relative) oscillations of the thermal cloud and the condensate. The in- and counter-phase oscillations are independent of each other in the case where the thermal cloud is inviscid for all modes studied, except the radial pulsations which couple them because the pressure perturbations of the condensate and the thermal cloud are governed by different adiabatic indices. If the thermal cloud is viscous, the two classes of oscillations are coupled, i.e. each type of motion involves simultaneously mass and entropy currents. The counter-phase oscillations are damped by the mutual friction between the condensate and the thermal cloud mediated by the vortex lattice. The damping is large for the values of the drag-to-lift ratio of the order of unity and becomes increasingly ineffective in either limit of small or large friction. An experimental measurement of a subset of these oscillation modes and their damping rates can provide information on the values of the phenomenological mutual friction coefficients, and hence the quasiparticle-vortex scattering processes in dilute atomic Bose gases.

description: William Thomas Stanley was the father-in-law of Ann, who provided these details. Before the war he lived in Arthur St, in the Blakenhall district of Wolverhampton. He was a pupil at St. Luke's School and worked for Royal London Insurance in their offices in Lichfield St. In 1914 he tried to enlist but failed the medical examination due to being short-sighted.

Having memorised the eye-test board he managed to obtain a place in the Royal Army Medical Corps. He served at Gallipoli and, probably, Salonika. During the Second World War William served as a volunteer fire-watcher. After his marriage to Winifred the couple lived at 59 Alexander Rd, Penn. However, his wife died within a week of his retirement. His second wife was named Lilian Pearson. He was a sidesman at St. Luke's Church in Wolverhampton until his death in 1980.
Localized Intersections of Non-Extremal p-branes and S-branes

description: A class of solutions to Supergravity in 10 or 11 dimensions is presented which extends the non-standard or semi-local intersections of Dp-branes to the case of non-extremal p-branes. The type of non-extremal solutions involved in the intersection is free and we provide two examples involving black-branes and/or D-\bar{D} systems. After a rotation among the time coordinate and a relatively transverse radial direction the solutions admit the interpretation of an intersection among D-branes and S-branes. We speculate on the relevance of these configurations both to study time dependent phenomena in the AdS/CFT correspondence as well as to construct cosmological brane-world scenarios within String Theory admitting accelerating expansion of the Universe.

description: This study examined the socioeconomic indicator of households in Igbo-Ora community of Oyo State. Two hundred households were randomly selected and used for this study. A quantitative survey was conducted with the use of interview schedule. Both descriptive and inferential statistics were used to summarize and analyze data collected. Results of analysis revealed that 37.5% and 32.0% were between the ages of 22-32 years and 33- 43 years respectively. Majority were males (95.5%), married (92.0%), Muslims (68.0%), and secondary school leavers (43.0%). Eighty-two percent of the respondents had household size of 1-5 persons with 92.0% females and 84.5% of males. Most (45.0%) of respondents were artisans, who diversified into farming. Respondents (45.0%) earn between N451,000 - N901,000 annually from their various income generating activities. About sixty percent had low socioeconomic status. There was no significant relationship between sex (χ2=0.036, p=0.668), marital status (χ2=2.033, p=0.566), religion (χ2=4.325, p=0.115); and socioeconomic status of respondents in Igbo-Ora community. However, significant relationship existed between occupation (χ2=13.383, p=0.031), educational attainment (χ2=3.723, p=0.054); and socioeconomic status in the community. The socioeconomic status of respondents in Igbo-Ora was low. It is recommended that they should be sensitized on financial management and investment, given that their socioeconomic status was not commensurate with their income.

description: As self-sustained oscillators, lasers possess the unusual ability to spontaneously synchronize. These nonlinear dynamics are the basis for a simple yet powerful stabilization technique known as injection locking, in which a laser's frequency and phase can be controlled by an injected signal. Due to its inherent simplicity and favorable noise characteristics, injection locking has become a workhorse for coherent amplification and high-fidelity signal synthesis in applications ranging from precision atomic spectroscopy to distributed sensing. Within integrated photonics, however, these injection locking dynamics remain relatively untapped--despite significant potential for technological and scientific impact. Here, we demonstrate injection locking in a silicon photonic Brillouin laser for the first time. Injection locking of this monolithic device is remarkably robust, allowing us to tune the laser emission by a significant fraction of the Brillouin gain bandwidth. Harnessing these dynamics, we demonstrate amplification of small signals by more than 23 dB. Moreover, we demonstrate that the injection locking dynamics of this system are inherently nonreciprocal, yielding unidirectional control and back-scatter immunity in an all-silicon system. This device physics opens the door to new strategies for phase noise reduction, low-noise amplification, and back-scatter immunity in silicon photonics.

description: An all-optical scheme to polarize nuclear spins in a single quantum dot is analyzed. The hyperfine interaction with randomly oriented nuclear spins presents a fundamental limit for electron spin coherence in a quantum dot; by cooling the nuclear spins, this decoherence mechanism could be suppressed. The proposed scheme is inspired by laser cooling methods of atomic physics and implements a "controlled Overhauser effect" in a zero-dimensional structure.

description: The study assessed the effect of vegetable production on the living standards of urban farmers in Lagos State. It focused on the profitability of vegetable farming and the living standards/conditions of vegetable farmers. Data were collected from 150 respondents using a structured questionnaire and analyzed using frequency counts, means, percentages and standard deviation. Hypothesis testing was done using Spearman’s Rank Correlation Coefficient. Major results show that pumpkin vegetables (mean=2.54) had high and uniform profitability among all farmers. Few farmers enjoy good living conditions but were generally food secure. The relationship between perceived profitability of vegetable farming and the standard of living of respondents show that all the variables (consumption, r=0.025, income, r=0.019, health, r=0.123 and education, r=0.025) had a positive correlation with perceived profitability of vegetable farming but were not significant. This implies that they had enough profit to live fairly well but their small farm sizes deprived them of some entitlements. Farmers were advised to increase their scale of operation so as to earn more from vegetable farming and hence increase their standards of living.

description: This collection of artefacts relate to Marion Munroe's father, Sergeant Ronald Swallow, who served in the King's Own Yorkshire Light Infantry and the Machine Gun Corps - Service No.20044. Ronald died c.1937/38 from TB which was believed to have been contracted due to a Gun Shot Wound received during the war. Before his death Ronald was receiving treatment at a hospital in Leeds (possibly St. James's). His wife, Elsie, was working as secretary a department of the War Office in Leeds. Although her father sometimes spoke of his wartime experiences, Marion was not particularly interested at the time - she was 14 when he died. Her mother received no pension afterwards as she remarried. The collection does not include Ronald's Military Medal which was 'lost' when someone 'borrowed' it for historical research purposes and never returned it.
Fertilizer Policy in Korea

Subjects: Environmental Economics and Policy

description: Farmers in Korea are often thought to be assisted by current fertilizer policy, since the government sells fertilizer to them at roughly 20 per cent below cost. However, this farm price is about 20 to 30 per cent above the international price. That is, fertilizer manufacturers are enjoying a nominal rate of protec­tion of more than 50 per cent. The fertilizer "subsidy" is really a mechanism by which taxpayers help farmers bear the direct cost of that protection. It involves large government outlays though, which the government would like to phase out. One option is to remove the "subsidy" which would force farmers to carry the full direct cost of that protection. Another option is to lower the rate of protection to fertilizer manufacturers. This paper provides estimates of the price changes required to eliminate government outlays under these alternative circumstances. It also quantifies the effects of such changes on fertilizer production and us
