description: Multipurpose ID is a combination of a Techno Smart Card carrying a twenty-digit universal identification number to record all purposeful information of an individual and a touch screen Smart Cell Phone for electronic surveillance. Both the units can work separately or together. Such a unique system would replace all possible documents procured by an individual during his life time. Apart from saving human resources, time, money and administrative complexities, the stack of files and papers in offices would also be reduced to fractional level. No Xerox, no documentation, no verification and no long queues for day-to-day pursuits. Just go for one click and the entire details of an individual would be available, that too fully genuine. The Nation would have a red letter day as the change will shape billion lives and bring respite to administrative machinery and public that has crumpled under the red tapism.

description: For a non-interacting Bose gas on a lattice we compute the shift of the critical temperature for condensation when random-bond and onsite disorder are present. We evidence that the shift depends on the space dimensionality D and the filling fraction f. For D -> infinity (infinite-range model), using results from the theory of random matrices, we show that the shift of the critical temperature is negative, depends on f, and vanishes only for large f. The connections with analogous results obtained for the spherical model are discussed. For D=3 we find that, for large f, the critical temperature Tc is enhanced by disorder and that the relative shift does not sensibly depend on f; at variance, for small f, Tc decreases in agreement with the results obtained for a Bose gas in the continuum. We also provide numerical estimates for the shift of the critical temperature due to disorder induced on a non-interacting Bose gas by a bichromatic incommensurate potential.

A study of inclusion behaviour during electroslag remelting
Creators: name: Burel, Bruno Charles
Publisher: name: University of British Columbia
Year: 2011

description: Different mechanisms are proposed in the literature to describe the formation and behaviour of inclusions during electroslag remelting: - dissolution in the liquid metal of the inclusions already present in the electrode and then renucleation in the freezing ingot. - total or partial dissolution in the slag. - exchange reactions between inclusions in the metal and the slag. - entrapment in the freezing ingot of pieces of slag skin or droplets of slag. The mechanism of dissolution of alumina inclusions in a 70/30 CaF₂/Al₂0₃ slag has been studied in detail. For this a new equilibrium diagram for the system CaF₂/Al₂0₃ has been proposed and the diffusion coefficient of alumina in the slag has been determined by the rotating disk system. In a 70/30 CaF₂/Al₂0₃ slag at 1518°C the diffusion coefficient was estimated as D = 8.5 10⁻⁹ m² sec⁻¹. Calculations of the extent of the dissolution of alumina particles in the slag predicted that big particles (800 μ) might dissolve only partially in the slag. Particles of this size were introduced artificially in electrodes, but after electroslag remelting a much larger number of relatively small (15 μ max) alumina, iron aluminates and iron oxide inclusions were found in the ingot. The same types of inclusions could also be observed in ingots obtained after remelting a Ferro Vac-E electrode. The presence of these inclusions cannot be explained by one the mechanisms proposed precedently (dissolution in the liquid metal and then renucleation or partial dissolution in the slag), but only by an electrolytic oxidation and electrolytic aluminum dissolution on the electrodes and then nucleation of deoxidation products in the freezing ingot.

description: In three previous papers, we investigated the travels of Marco Polo using Google Earth and Wikimapia. We reconstructed the Polo’s travels from Beijing to Xanadu, from Sheberghan to Kashgar, and from Kashgar to Xanadu. Here we propose Polo's travel in Persia. The place of a Mulehet Castle, close to Ferdows in the Tunocain county, is given. It is possible that Marco Polo was referring to this castle near Ferdows, when he was reporting about the Old Man of the Mountain, and not to the Alamut Castle.

description: We show in detail that the Hawking temperature calculated from the surface gravity is in agreement with the result of exact semi-classical radiation spectrum for higher dimensional linear dilaton black holes in various theories. We extend the method derived first by Clément-Fabris-Marques for 4-dimensional linear dilaton black hole solutions to the higher dimensions in theories such as Einstein-Maxwell-Dilaton, Einstein-Yang-Mills-Dilaton and Einstein-Yang-Mills-Born-Infeld-Dilaton. Similar to the Clément-Fabris-Marques results, it is proved that whenever an analytic solution is available to the massless scalar wave equation in the background of higher dimensional massive linear dilaton black holes, an exact computation of the radiation spectrum leads to the Hawking temperature T_{H} in the high frequency regime. The significance of the dimensionality on the value of T_{H} is shown, explicitly. For a chosen dimension, we demonstrate how higher dimensional linear dilaton black holes interpolate between the black hole solutions with Yang-Mills and electromagnetic fields by altering the Born-Infeld parameter in aspect of measurable quantity T_{H}. Finally, we explain the reason of, why massless higher dimensional linear dilaton black holes cannot radiate.

Some effects of cool temperatures on flower production, fruit set and growth of four tomato varieties and their Fl hybrids.

Year: 2011

description: It is desirable to develop tomato varieties which have the character of being able to set fruit at relatively cool temperature between 10°C to 15.5°C for commercial production in Canada. The tomato varieties Puck, Bonny Best, Immur, Prior Beta, Cold Set and some of their reciprocal Fl hybrids were grown both in greenhouses and in growth chambers under two different temperature levels, experiments were carried out to study fruit, set and the effects of self and cross-pollination on fruit development in four varieties and the Fl hybrids of PxBB, BBxP, IPBxBB, BBxIPB, CSxBB, and BBxCS. Under both cool and warm temperatures, the percentage of fruit set and also size of fruit were increased when cross-pollination was used in contrast to self-pollination. Under cool temperature, all Fl hybrid lines had a higher percentage of fruit set than their two parents, but in warm temperature the Fl hybrid lines had a intermediate percentage between those of the two parents. Under both temperature regimes there were distinct differences among lines in the time intervals for different component stages in the life cycle. Cool temperatures increased lengths of these intervals, but relative difference in lengths of interval was clearly evident. Among the ten lines, IPB was notably the earliest variety to ripe first fruit. In the first component interval from seeding to flower opening, IPB was the earliest and Bonny Best the latest; however, for the two succeeding intervals, namely flowering to fruit set and fruit set to ripening, IPB did not have the shortest intervals or most rapid growth. In fact Puck variety was better than IPB for the second component interval, and in the third interval, (BBxIPB) Fl and the reciprocal cross were the earliest. This sort of variability suggests recombination to put the earliest component stages together to synthesize a very early line.

description: We analyse the breaking of U-spin on a group theoretical basis. Due to the simple behaviour of the weak effective hamiltonian under U-spin and the unique structure of the breaking terms such a group theoretical analysis leads to a manageable number of parameters. Several applications are discussed, including the decays B -> J/psi K and B -> D K.

description: Objective: To investigate changes in pain, disability, anxiety, depression, somatic symptom burden and quality of life among patients with CLBP after the implementation of a physiotherapy regimen, and to examine the association of SSDs with the above parameters.
 Materials and methods: Patients with CLBP recruited using random systematic sampling and completed a battery of questionnaires, the Numerical Pain Scale (NPS) for pain, the Rolland-Morris for disability (RMQ), the EuroQoL 5-dimension 5-level (EQ-5D-5L) for health status, the Somatic Symptom Scale-8 (SSS-8) for SSDs, the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression. A paired t-test, Wilcoxon signed test and McNemar test were used for quantitative, ordinal and qualitative variables respectively. Pearson’s correlation coefficient r was tested examining associations between SSS-8 and NPS, RMQ, EQ-5D-5L and HADS. The level of statistical significance was set at p<0.05.
 Results: 32 subjects participated of which 13 were male, mean age 57.3 years (16,4), 46.9% were overweight and 18.8% obese. After treatment, significant reductions were observed in pain intensity [from 5.06 (2.17) to 3.46 (2.02)], disability [from 7.44 (4.70) to 6.31 (5.56)] and somatic symptom burden [from 9.25 (4.59) to 7.81 (4.13)]. Additional improvement was found in mean EQ-5D-5L VAS score [from 69.66 (13.54) to 76.23 (15.81)], but no in EQ-5D-5L index value, anxiety and depression. Level of pain was improved significant, since 28.1% of patients mentioned severe pain in the beginning and the corresponding proportion was 7.7% after the treatment, while in contract frequency of having regular exercising more than twice per week remained stable at the baseline and at the end of intervention (43.8% and 42.3%, respectively). A moderate negative correlation was noted between primary score of SSS-8 and EQ-5D-5L VAS (r=-0.46), whereas a moderate positive association was found between SSS-8 and NPS change (r=0.39).
 Conclusion: Physiotherapy regimen was shown to be effective in patients with CLBP, by improving pain, disability, SSDs and health status. A somatic symptom burden was significant correlated with pain and health-related quality of life.

description: A new miniature species of the freshwater fish genus Priocharax is described from the Rio Jamari, Rio Madeira drainage, Amazon basin. Priocharax varii sp. n. is the fourth species currently recognized in the genus and shares with the other three the presence of a conspicuous larval pectoral fin in adults, a fully toothed maxilla, a triangular pseudotympanum situated anterior to the fifth vertebra and a tiny size combined with a translucent body. The new species is diagnosed from congeners in having an adipose fin, a unique feature within Priocharax. Molecular identification of the new species and the other valid Priocharax species supports the morphological findings. A brief discussion on the presence/absence of the adipose fin in Characiformes is provided.

description: It is well known that a detector, coupled linearly to a quantum field and accelerating through the inertial vacuum with a constant acceleration $g$, will behave as though it is immersed in a radiation field with temperature $T=(g/2π)$. We study a generalization of this result for detectors moving with a time-dependent acceleration $g(τ)$ along a given direction. After defining the rate of excitation of the detector appropriately, we evaluate this rate for time-dependent acceleration, $g(τ)$, to linear order in the parameter $η= \dot g / g^2$. In this case, we have three length scales in the problem: $g^{-1}, (\dot g/g)^{-1}$ and $ω^{-1}$ where $ω$ is the energy difference between the two levels of the detector at which the spectrum is probed. We show that: (a) When $ω^{-1} \ll g^{-1} \ll (\dot g/g)^{-1}$, the rate of transition of the detector corresponds to a slowly varying temperature $T(τ) = g(τ)/2 π$, as one would have expected. (b) However, when $ g^{-1}\ll ω^{-1} \ll (\dot g/g)^{-1}$, we find that the spectrum is modified \textit{even at the order $\mathcal{O}(η)$}. This is counter-intuitive because, in this case, the relevant frequency does not probe the rate of change of the acceleration since $(\dot g/g) \ll ω$ and we certainly do not have deviation from the thermal spectrum when $\dot g =0$. This result shows that there is a subtle discontinuity in the behaviour of detectors with $\dot g = 0$ and $\dot g/g^2$ being arbitrarily small. We corroborate this result by evaluating the detector response for a particular trajectory which admits an analytic expression for the poles of the Wightman function.

Gas driven massive black hole binaries: signatures in the nHz gravitational wave background

description: Pulsar timing arrays (PTAs) measure nHz frequency gravitational waves (GWs) generated by orbiting massive black hole binaries (MBHBs) with periods between 0.1-10 yr. Previous studies on the nHz GW background assumed that the inspiral is purely driven by GWs. However, torques generated by a gaseous disk can shrink the binary much more efficiently than GW emission, reducing the number of binaries at these separations. We use simple disk models for the circumbinary gas and for the binary-disk interaction to follow the orbital decay of MBHBs through physically distinct regions of the disk, until GWs take over their evolution. We extract MBHB cosmological merger rates from the Millennium simulation, generate Monte Carlo realizations of a population of gas driven binaries, and calculate the corresponding GW amplitudes of the most luminous individual binaries and the stochastic GW background. For steady state alpha-disks with alpha>0.1 we find that the nHz GW background can be significantly modified. The number of resolvable binaries is however not changed by the presence of gas; we predict 1-10 individually resolvable sources to stand above the noise for a 1-50 ns timing precision. Gas driven migration reduces predominantly the number of small total mass or unequal mass ratio binaries, which leads to the attenuation of the mean stochastic GW--background, but increases the detection significance of individually resolvable binaries. The results are sensitive to the model of binary--disk interaction. The GW background is not attenuated significantly for time-dependent models of Ivanov, Papaloizou, & Polnarev (1999).

description: Recent optical conductivity experiments of doped graphene in the infrared regime reveal a strong background in the energy region between the intra and interband transitions difficult to explain within conventional pictures. We propose a phenomenological model taking into account the marginal Fermi liquid nature of the quasiparticles in graphene near the neutrality point that can explain qualitatively the observed features. We also study the electronic Raman signal and suggest that it will also be anomalous.

description: We investigate here the representability of integers as sums of triangular numbers, where the $n$-th triangular number is given by $T_n = n(n + 1)/2$. In particular, we show that $f(x_1,x_2,..., x_k) = b_1 T_{x_1} +...+ b_k T_{x_k}$, for fixed positive integers $b_1, b_2,..., b_k$, represents every nonnegative integer if and only if it represents 1, 2, 4, 5, and 8. Moreover, if `cross-terms' are allowed in $f$, we show that no finite set of positive integers can play an analogous role, in turn showing that there is no overarching finiteness theorem which generalizes the statement from positive definite quadratic forms to totally positive quadratic polynomials.

description: In a classical theory of gravity, the Barbero-Immirzi parameter ($η$) appears as a topological coupling constant through the Lagrangian density containing the Hilbert-Palatini term and the Nieh-Yan invariant. In a quantum framework, the topological interpretation of $η$ can be captured through a rescaling of the wavefunctional representing the Hilbert-Palatini theory, as in the case of the QCD vacuum angle. However, such a rescaling cannot be realized for pure gravity within the standard (Dirac) quantization procedure where the second-class constraints of Hilbert-Palatini theory are eliminated beforehand. Here we present a different treatment of the Hilbert-Palatini second-class constraints in order to set up a general rescaling procedure (a) for gravity with or without matter and (b) for any choice of gauge (e.g. time gauge). The analysis is developed using the Gupta-Bleuler and the coherent state quantization methods.

description: Risk bounds for Classification and Regression Trees (CART, Breiman et. al. 1984) classifiers are obtained under a margin condition in the binary supervised classification framework. These risk bounds are obtained conditionally on the construction of the maximal deep binary tree and permit to prove that the linear penalty used in the CART pruning algorithm is valid under a margin condition. It is also shown that, conditionally on the construction of the maximal tree, the final selection by test sample does not alter dramatically the estimation accuracy of the Bayes classifier. In the two-class classification framework, the risk bounds that are proved, obtained by using penalized model selection, validate the CART algorithm which is used in many data mining applications such as Biology, Medicine or Image Coding.

description: Many astrophysical problems arising within the context of ultra-high energy cosmic rays, very-high energy gamma rays or neutrinos, require calculation of the flux produced by sources tracing the distribution of galaxies in the Universe. We discuss a simple weighting scheme, an application of the method introduced by Lynden-Bell in 1971, that allows the calculation of the flux sky map directly from a flux-limited galaxy catalog without cutting a volume-limited subsample. Using this scheme, the galaxy distribution can be modeled up to large scales while representing the distribution in the nearby Universe with maximum accuracy. We consider fluctuations in the flux map arising from the finiteness of the galaxy sample. We show how these fluctuations are reduced by the weighting scheme and discuss how the remaining fluctuations limit the applicability of the method.

The impact on emotional well-being: experiences of being a palliative care volunteer
Creators: name: Coleman, Helena
Publisher: name: Lancaster University
Year: 2020

description: The impact of palliative and end-of-life care volunteers’ roles in relation to their emotional well-being is explored in this thesis. Firstly, a systematic review and thematic synthesis on the emotional experiences of being a palliative care volunteer provides an overview of existing research. The thematic synthesis employed an iterative three-stage synthesis of 22 included papers. Themes identified include intrinsic and extrinsic challenges, personal gain and the development of relationships. Volunteers face unique challenges; however, they also experience a number of positive impacts on their emotional well-being. It is important to monitor how volunteers cope and provide appropriate support. Few papers focus directly on the emotional experiences of volunteers and a need for research that explores these experiences is highlighted. Secondly, an interpretative phenomenological analysis study was conducted exploring the impact of hospice volunteers’ roles in relation to their emotional well-being. Ten participants were recruited across three hospices and data were collected via semi-structured interviews. Data were analysed using interpretative phenomenological analysis and four themes were developed: (1) it can be challenging; (2) it’s where I’m meant to be; (3) managing death; (4) the importance of connection. Although there are psychosocial benefits for volunteers in their role, considering challenges is important to ensure that support is provided to help volunteers manage these challenges. Thirdly, a critical appraisal: a reflection on the experience of conducting the thesis, focusing on ideas for future research, boundaries and other areas of concern or interest throughout. This thesis highlights the need for more research into the emotional experiences of palliative and end-of-life care volunteers and indicates value in implementing formal support for volunteers.

description: The light scalar mesons, discovered over forty years ago, became a challenge for the naive quark-antiquark model from the outset. At present the nontrivial nature of these states is no longer denied practically anybody. Two-photon physics has made a substantial contribution to understanding the nature of the light scalar mesons. Recently, it entered a new stage of high statistics measurements. We review the results concerning two-photon production mechanisms of the light scalars, based on the analysis of current experimental data.

description: Archaeological plaster casts, namely highly precise reproductions of ancient Greek and Roman sculptures, have had a tumultuous history. Once considered an essential feature of nineteenth-century country homes and art schools, casts suffered a dramatic twentieth-century downturn in popularity. Nonetheless, some collections, particularly those held within university museums, weathered this era. The recent “replication turn” in modern scholarship has directed new attention to these objects, generating more knowledge than ever before about casts’ own histories, their unique materialities, and contexts of display. Such scholarship has outlined the many values that casts possess as objects in their own right. However, less research has been directed toward understanding how the objects “work in practice” within the museums that display them today. My thesis aims to shed light on this significant issue. Through visitor studies research conducted at the Ashmolean Museum, Oxford, I analyse the diverse value(s) that contemporary museum audiences attach to casts. While many of the value(s) identified by the Ashmolean’s users align with those discussed in scholarship, I note that there are many important nuances. I also consider the special influence that the setting of a university museum such as the Ashmolean has on perceptions of casts. I argue that it is not only the educationally focused setting but the particular disciplinary value system of the Museum’s interpretive community of Classical Archaeologists that impacts on the values associated with the casts. Furthermore, I tackle the thorny issue of authenticity, which also influences how the casts are interpreted. I demonstrate that their status as copies of ancient sculptures, works of art that are highly embedded within Western culture, results in their value being inevitably somewhat dependent upon their ancient referents. Finally, I explore how recognising the “castness” inherent in all things can inform wider debates over contemporary museum and heritage practice.

description: Graphene antidot lattices constitute a novel class of nano-engineered graphene devices with controllable electronic and optical properties. An antidot lattice consists of a periodic array of holes which causes a band gap to open up around the Fermi level, turning graphene from a semimetal into a semiconductor. We calculate the electronic band structure of graphene antidot lattices using three numerical approaches with different levels of computational complexity, efficiency, and accuracy. Fast finite-element solutions of the Dirac equation capture qualitative features of the band structure, while full tight-binding calculations and density functional theory are necessary for more reliable predictions of the band structure. We compare the three computational approaches and investigate the role of hydrogen passivation within our density functional theory scheme.

description: Quantum tunneling is an exceedingly sensitive probe of inter-electrode separation, electrode area, the type of electrode material and the nature of intervening insulator. Our devices are based on variable overlap area of the quasi 1D–nanowires1,2, electrodes placed on two opposing atomically flat surfaces. A generic nanoTrek® device is composed of two plates separated by a very thin layer of insulator, e.g. soft-matter spacer, air, vacuum. Several hundred to many thousands quasi-1D nanowires are deposited on each plate. The device can be thought of as a 2D plate/insulating layer (liquid)/ 2D plate sandwich. The nanowires on the two opposing surfaces facing each other and aligned with each other form elongated electrodes in the tunneling process. We have built and successfully tested devices composed of two individual Si chips separated with monolayer of soft-matter spacer (3,4,5)
 In this poster we describe the concept leading to 3D monolithic nanoTrek® device specifically suited for sensing dynamic quantities. Both 2D substrates are part of one monolithic unit. One plate is suspended on etched beams. Depending on desired functionality or performance there can be one to four beams with width-to-length-to-thickness ratios designed for specific device sensitivity. Nanowires are fabricated on the top surface of the larger, bottom plate and, opposing them, at the bottom surface of a movable, top plate. Separation between the plates is in the range of 1–10 nm. We discuss several different candidate processes suitable for fabrication of our monolithic devices.

description: This paper reviews the overview of the dynamic shortest path routing problem and the various neural networks to solve it. Different shortest path optimization problems can be solved by using various neural networks algorithms. The routing in packet switched multi-hop networks can be described as a classical combinatorial optimization problem i.e. a shortest path routing problem in graphs. The survey shows that the neural networks are the best candidates for the optimization of dynamic shortest path routing problems due to their fastness in computation comparing to other softcomputing and metaheuristics algorithms

Some effects of urea and nitrate nitrogen on the growth and composition of cranberry.
Creators: name: Leschyson, Margaret Ann
Publisher: name: University of British Columbia
Year: 2011

description: Two similar greenhouse experiments wore carried out to observe the effects of 2 forms of nitrogen fertilizer, (nitrate and urea), each at 5 rates, (0, 30, 60, 90, and 120 lb N per acre), on cranberry plants, (Vaccinium macrocarpon Ait. cv. McFarlin). In the first experiment, treatments were applied to cuttings which had been rooted for a short time whereas in the second experiment, cuttings which had been rooted for 7 months as well as cuttings which had just been rooted were used. Growth measurements and foliar mineral analyses were carried out on shoots collected from actively growing plants 2 and 16 weeks after differential treatment in the first experiment and 14 weeks after treatment in the second experiment. In both experiments, N fertilization soon after rooting enhanced vegetative growth. Greater vegetative growth was obtained with nitrate in the first experiment but with urea in the second. Analysis of variance indicated that treatments which increased growth also increased foliar N and decreased foliar P, Fe, and Ca. In the first experiment, growth measurements were linearly correlated with foliar Mg or Mn or both in the first harvest, but in the second harvest, correlations were with foliar N, P, and K content. In the second experiment, cuttings which had been rooted for some time initiated more shoots and leaves, but did not respond to N treatments.

High energy improved scalar quantum field theory from noncommutative geometry without UV/IR-mixing

description: We consider an interacting scalar quantum field theory on noncommutative Euclidean space. We implement a family of noncommutative deformations, which -- in contrast to the well known Moyal-Weyl deformation -- lead to a theory with modified kinetic term, while all local potentials are unaffected by the deformation. We show that our models, in particular, include propagators with anisotropic scaling z=2 in the ultraviolet (UV). For a Φ^4-theory on our noncommutative space we obtain an improved UV behaviour at the one-loop level and the absence of UV/IR-mixing and of the Landau pole.

description: Direct photon emission in heavy-ion collisions is calculated within the relativistic microscopic transport model UrQMD. We compare the results from the pure transport calculation to a hybrid-model calculation, where the high-density part of the evolution is replaced by an ideal 3-dimensional fluiddynamic calculation. The effects of viscosity, present in the transport model but neglected in ideal fluid-dynamics, are examined. We study the contribution of different production channels and non-thermal collisions to the spectrum of direct photons. Detailed comparison to the measurements by the WA~98-collaboration are undertaken.

Community consequences of rapid transit
Creators: name: Herbert, Larry
Publisher: name: University of British Columbia
Year: 2011

description: The hypothesis: Urban development will be stimulated by introducing rapid transit into a city's structure. Therefore, rapid transit can be used by planners as a tool to control and implement predetermined development of varying natures within the city. Chapter 1 discusses the role which transportation in general can play in changing the city. It is examined as a changing technology, as a cause of centralization and decentralization, and as a theory explaining urban structure. Chapter 2 begins by discussing theory of rapid transit planning after which three case studies are presented — Chicago, Cleveland, and Toronto. Each of these cities has been chosen to illustrate different rapid transit planning approaches. Chicago represents a system oriented to the central city; Cleveland represents a system oriented to the suburbs; and Toronto represents a new system oriented to the central city but expanding into suburban areas. Chapter 3 applies the theory and case study information to Vancouver, three theoretical rapid transit stations are proposed. Nanaimo-Hastings represents the impact rapid transit has upon a neighborhood of older homes adjacent to a high-quality commercial shopping strip. Main-Hastings/Pender (Chinatown-Strathcona) represents the relationship of rapid transit to the edge of the core area and to urban renewal. Georgia-Granville represents the integration of rapid transit in the core. In each case the effects upon adjacent land use are postulated.
