description: The presence of abdominal or back pain, weight loss and elevated erythrocyte sedimentation rate is characteristic of the inflammatory abdominal aortic aneurysms. Low-grade fever is sometimes identified. Other inflammatory markers, such as white blood cell count, C reactive protein, anti-nuclear antibody and IgG4 levels can be elevated. Computed tomography is the exam of choice, showing characteristically the mantle sign. Steroids improve the symptomatology and reduce inflammation, but do not treat the aneurysm. The choice of interventions: open surgical repair or endovascular aneurysm repair can be considered according to the available expertise, patient risk factors, anatomic aneurysm criteria and presence of hydronephrosis.

description: There are many solutions to the Einstein field equations that demonstrate naked singularity (NS) formation after regular evolution. It is possible, however, that such a quantum effect as particle creation prevents NSs from forming. We investigate the relation between the curvature strength and the quantum effects of NSs in a very wide class of spherical dust collapse. Through a perturbative calculation, we find that if the NS is very strong, the quantum particle creation diverges as the Cauchy horizon is approached, while if the NS is very weak, the creation should be finite. In the context of cosmic censorship, strong NSs will be subjected to the backreaction of quantum effects and may disappear or be hidden behind horizons, while weak NSs will not.

description: Although rare, the persistence of a sciatic artery is a clinically significant vascular variant, since it is often associated with complications such as aneurysm formation, thrombosis and ischaemia. We present the case of a patient with signs of subacute ischaemia on the right lower limb and a pulsatile mass in the right inferior gluteal region. CT angiography revealed a bilateral persistent sciatic artery (PSA) complicated by aneurysm formation and embolization of distal popliteal artery. Treatment included a femoro-popliteal bypass, ligation of the popliteal artery above the anastomosis and embolization of the aneurysmal lesion.

Characterisation and modelling of a uniformly graded, well-rounded coarse sand
Creators: name: Rouse, Pascale C.
Publisher: name: University of British Columbia
Year: 2009

description: Strength parameters and intrinsic properties of sand are very important for engineering design. It is well known that such properties depend on factors including grain size distribution, fines content, mineralogy and grain shape. Recently, several authors have sought to establish a relation between the constant volume friction angle, as well as the maximum and minimum void ratios, and the roundness of the sand grains. Little information exists on well-rounded sands. A series of triaxial tests were performed on a uniformly graded, well-rounded coarse sand (R=0.81). Interpretation of the results confirms the available relations, and provides a link between the data on commonly found sands (0.2<R<0.7) and glass beads (R≅1.0). Additionally a comparison of drained and undrained triaxial test data indicates ϕ[sub MC] ≅ ϕ[sub PT] ≠ cv, ϕ[sub CV] ≅ϕ[sub MO], ϕ[sub MO] ≅ϕ[sub PT] + 3° and ϕ[sub CV] is very similar to ϕ[sub rep]. The behaviour of the well-rounded sand is modelled using the critical state soil mechanics constitutive model, NorSand. The results show that the parameters needed for the model fall within the expected range of values, and that NorSand captures both the drained and undrained response of the sand in triaxial testing. However, the volumetric coupling coefficient N, shows an unusual value indicative of unusual dilation of this sand. To account for this, a modification of the flow rule is proposed. In addition, the NorSand constitutive model is implemented in the commercially available software FLAC. For this, the standard method used within FLAC, F=0, will not work. But by solving F = 0 it is possible to introduce any critical state soil mechanics (CSSM) constitutive model. This approach is described in detail for two selected CSSM models, Original Cam Clay and NorSand.
TÉCNICA KISSING STENT NO TRATAMENTO DE ESTENOSE DA ARTÉRIA INOMINADA

description: Abstract Introduction: The presence of symptomatic atherosclerotic stenosis of the innominate artery is an uncommon condition. The authors report the use of kissing stent technique in right subclavian and common carotid arteries with covered stents and cerebral protection by direct clamping of common carotid artery, as a hybrid endovascular alternative to treat symptomatic stenosis of the innominate artery. Case Report: A 75-year-old male was admitted to Vascular Surgery Department with repeated transient ischemic attacks (TIA’s) of the right cerebral hemisphere, resulting in transitory left hemiparesis. Computerized tomography angiography (CTA) excluded significant carotid lesions and revealed stenosis of the innominate artery associated with mural thrombus that extended to the bifurcation. The right common carotid artery and axillary artery were surgically exposed. Brain protection was achieved by direct clamping of the common carotid artery and subsequently carotid and axillary retrograde endovascular access was obtained. Two balloon-expandable covered stents were placed in the innominate, subclavian and right common carotid arteries, using the kissing stent technique. At the end of the procedure, a good permeability of the revascularized arteries was verified and a direct expulsion of eventual embolic material was performed prior to declamping. The postoperative period was uneventful. Conclusion: The kissing stent technique, with covered stents, in innominate, right subclavian and common carotid arteries with direct protection of the common carotid by clamping is a possible and minimally invasive solution for the treatment of symptomatic stenosis of the innominate artery. Keywords: Endovascular treatment, kissing stent technique, innominate artery.

Dynamic modelling of extreme speed profiles of dry flowing avalanches
Creators: name: Borstad, Christopher Paul
Publisher: name: University of British Columbia
Year: 2010

description: A brief review of different approaches to avalanche dynamics modelling is considered, drawing on observations and knowledge of avalanche behaviour and analogies with other physical phenomena. The numerical model used for this analysis, DAN, is described with respect to the formulation of the equations of momentum and continuity. Avalanche path geometry is approximated as a rectangular channel with the possibility of variable width. The flow mass is discretized longitudinally into a variable number of constant-volume blocks. The uncertainty surrounding the dynamics of frontal ploughing of undisturbed snow, basal erosion, and mass entrainment is discussed. In order to avoid this uncertainty, which is implicit when modelling a slab avalanche beginning from rest in the starting zone, the calculations in DAN begin near the middle of the slope where the flow is expected to achieve maximum speed. Knowledge of the maximum probable speed for an extreme avalanche is used to supply an initial, non-zero speed to the flow near the middle of the path, and entrainment is assumed negligible as the flow decelerates. A sensitivity analysis explores theoretical considerations surrounding the modelling of a flow mass in multiple dimensions, given this new procedure as well as traditional from-rest approaches. The model is shown to be more sensitive to changes in flow width than flow length or depth. DAN calculations are compared against examples of recorded extreme avalanche data, with generally good agreement. The new modelling procedure was able to reproduce the observed sharp deceleration of avalanche frontal speed in runout zones. This is worthy of remark, because most decisions about land use planning and hazard assessment are made in the lower reaches of avalanche paths.

description: In the studied axisymmetric case of the central four-body problem, the axis of symmetry is defined by two unequal-mass bodies, while the other two bodies are situated symmetrically with respect to this axis and have equal masses. Here, we consider a special case of the problem and assume that three of the masses are equal. Using a recently found analytical solution of the general case, we formulate the equations of condition for three equal masses analytically and solve them numerically. A complete description of the problem is given by providing both the coordinates and masses of the bodies. We show furthermore how the three-equal-mass solutions are related to the general case in the coordinate space. The physical aspects of the configurations are also studied and discussed.

description: An industry cluster is a geographically bounded collection of similar and/or related firms that together create competitive advantages for member firms and the local economy. The targeting of economic development programs at industry clusters provides three principal advantages: multiplier effects are stronger, employment growth potential is enhanced, and new firm spin-offs are promoted. The Clemson University Regional Economic Development Research Laboratory (REDRL) targeting method uses a screening process to identify local industry clusters with high potential for future growth. The region’s industries must pass five screens to be selected as a targeted cluster: substantial local presence as indicated by number of establishments and employees, industry employment in the region is growing, the region is relatively specialized in the industry (LQ> 1.0), and local employment growth exceeds the national industry average. Next, industry value chains are identified to determine if linked industries are good prospects for targeting. Finally, the identified high potential industry clusters are rated according to workers’ wages, potential future employment growth, import substitution potential, average plant size, and linkages to the local economy. Comparisons of these industry characteristics provide communities with insights regarding the potential economic and fiscal impacts associated with the attraction of an establishment in one of the target industries. In summary, the industry cluster targeting approach provides community leaders with (1) a list of industries for which they have a reasonable likelihood of attracting and (2) information regarding the likely benefits and costs associated with each industry. As such, a targeting approach permits communities to use their limited industrial development resources more efficiently to meet their industrial development goals.

description: We present arguments suggesting that large size overlapping instantons are the driving mechanism of the confinement-deconfinement phase transition at nonzero chemical potential mu. The arguments are based on the picture that instantons at very large chemical potential in the weak coupling regime are localized configurations with finite size rho~1/mu. At the same time, the same instantons at smaller chemical potential in the strong coupling regime are well represented by the so-called instanton-quarks with fractional topological charge 1/Nc. We estimate the critical chemical potential mu_c(T) where this phase transition takes place as a function of temperature in the domain where our approach is justified. In this picture, the long standing problem of the "accidental" coincidence of the chiral and deconfinement phase transitions at nonzero temperature (observed in lattice simulations) is naturally resolved. We also derive results at nonzero isospin chemical potential mu_I where direct lattice calculations are possible, and our predictions can be explicitly tested.

A technique for sub-pixel temperature retrieval from multispectral imagery and its application to Quesnel Lake, British Columbia
Creators: name: Sentlinger, Gabriel Isaac
Publisher: name: University of British Columbia
Year: 2009

description: Water temperature is a significant environmental indicator in lakes, rivers and streams. It is important to many resource management and environmental fields: forestry practices in adjacent lands modify runoff patterns which in-turn affects water temperatures; accelerated glacial melting caused by climate change increases the flux of cold water; and spawning salmon stocks are lethally affected by thermal shock from small (<5°C) temperatures changes. Quesnel Lake in the interior of British Columbia, Canada, is an important lake in all of these respects, and is the subject of this study due to recent mass mortality of spawning salmon believed to be caused by extreme temperature fluctuations. The conventional means of tracking temperature are in-situ temperature loggers installed in a small number of critical locations. This approach is costly and prone to data loss however, and does not provide a spatially comprehensive measure of lake temperature patterns. Coupled with satellite Thermal Infrared (TIR) imagery, the two measures can provide a contiguous dataset in space, depth, and time. Achieving an adequate balance between temporal and spatial coverage in TIR imagery can be difficult. Sensors with a sufficiently short revisit time often do not provide adequate spatial resolution to resolve narrow reaches of lakes and rivers. The MODIS sensor provides very high temporal coverage, up to four visits per day, but at a resolution of 1km, which is insufficient for Quesnel Lake's narrow reaches. This research presented in this thesis attempts to reconcile this deficiency in available TIR products, to produce an adequately accurate and fine spatial and temporal resolution water surface temperature dataset. By using a priori vectorized water boundary data, we estimate the sub-pixel surface temperature to within 1°C using a gradient descent solution to the mixed pixel at-sensor radiance equation. Ground-leaving radiance is estimated from standard MODIS temperature and emissivity data products for pure pixels and a simple regression technique to estimate atmospheric effects. The resulting algorithm is simple, effective, and useful for scientists without extensive remote sensing expertise, essentially unlocking a largely untapped resource for limnological and hydrological studies.

description: We report the first experimental study of cluster size distributions in electrostatically driven granular submonolayers. The cluster size distribution in this far-from-equilibrium process exhibits dynamic scaling behavior characteristic of the (nearly equilibrium) Ostwald ripening, controlled by the attachment and detachment of the "gas" particles. The scaled size distribution, however, is different from the classical Wagner distribution obtained in the limit of a vanishingly small area fraction of the clusters. A much better agreement is found with the theory of Conti et al. [Phys. Rev. E 65, 046117 (2002)] which accounts for the cluster merger.

description: Considering the collisional energy loss rates of heavy quarks from hard light parton interactions the total energy loss of a charm quark for a static medium has been computed. For the energy range $E\sim (5-10)$ GeV of charm quark, it is found to be almost same order as that of radiative ones estimated to a first order opacity expansion. The collisional energy loss will become much more important for lower energy charm quarks and this feature could be very interesting for phenomenology of hadrons spectra. Using such collisional energy loss rates we estimate the momentum loss distribution employing a Fokker-Planck equation and the total energy loss of a charm quark for an expanding quark-gluon plasma under conditions resembling the RHIC energies. The fractional collisional energy loss is found to be suppressed by a factor of 5 as compared to static case and does not depend linearly on the system size. We also investigate the heavy to light hadrons $D/π$ ratio at moderately large (5-10) GeV/$c$ transverse momenta and comment on its enhancement.

description: It is well-known that if $ξ$ is a smooth vector field on a given Riemannian manifold $M^n$ then $ξ$ naturally defines a submanifold $ξ(M^n)$ transverse to the fibers of the tangent bundle $TM^n$ with Sasaki metric. In this paper, we are interested in transverse totally geodesic submanifolds of the tangent bundle. We show that a transverse submanifold $N^l$ of $TM^n$ ($1 \leq l \leq n$) can be realized locally as the image of a submanifold $F^l$ of $M^n$ under some vector field $ξ$ defined along $F^l$. For such images $ξ(F^l)$, the conditions to be totally geodesic are presented. We show that these conditions are not so rigid as in the case of $l=n$, and we treat several special cases ($ξ$ of constant length, $ξ$ normal to $F^l$, $M^n$ of constant curvature, $M^n$ a Lie group and $ξ$ a left invariant vector field)

description: The growth in the demand for precisely crafted many-body systems of spin-$1/2$ particles/qubits is due to their top-notch versatility in application-oriented quantum-enhanced protocols and the fundamental tests of quantum theory. Here we address the question: how quantum is a chain of spins? We demonstrate that a single element of the density matrix carries the answer. Properly analyzed it brings information about the extent of the many-body entanglement and the non-locality. This method can be used to tailor and witness highly non-classical effects in many-body systems with possible applications to quantum computing, ultra-precise metrology or large-scale tests of quantum mechanics. As a proof of principle, we investigate the extend of non-locality and entanglement in ground states and thermal states of experimentally accessible spin chains.

description: A theoretical and experimental study of the fragmentation of closed thin shells made of a disordered brittle material is presented. Experiments were performed on brown and white hen egg-shells under two different loading conditions: fragmentation due to an impact with a hard wall and explosion by a combustion mixture giving rise to power law fragment size distributions. For the theoretical investigations a three-dimensional discrete element model of shells is constructed. Molecular dynamics simulations of the two loading cases resulted in power law fragment mass distributions in satisfactory agreement with experiments. Based on large scale simulations we give evidence that power law distributions arise due to an underlying phase transition which proved to be abrupt and continuous for explosion and impact, respectively. Our results demonstrate that the fragmentation of closed shells defines a universality class different from that of two- and three-dimensional bulk systems.

description: Fast and accurate resolution of electromagnetic problems via the \ac{BEM} is oftentimes challenged by conditioning issues occurring in three distinct regimes: (i) when the frequency decreases and the discretization density remains constant, (ii) when the frequency is kept constant while the discretization is refined and (iii) when the frequency increases along with the discretization density. While satisfactory remedies to the problems arising in regimes (i) and (ii), respectively based on Helmholtz decompositions and Calderón-like techniques have been presented, the last regime is still challenging. In fact, this last regime is plagued by both spurious resonances and ill-conditioning, the former can be tackled via combined field strategies and is not the topic of this work. In this contribution new symmetric scalar and vectorial electric type formulations that remain well-conditioned in all of the aforementioned regimes and that do not require barycentric discretization of the dense electromagnetic potential operators are presented along with a spherical harmonics analysis illustrating their key properties.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Aims Inflammation is common in clinical practice and often results in significant complications. The study was performed in search of a novel anti-inflammatory agent for inflammation modulation which would be useful for cardiovascular disorders and various clinical scenarios. Materials and methods A crushed red rose extract was prepared from the petals, and it was processed for analysis. The extract was tested on HUVEC cells at various concentrations. By microscopic analysis of cells, a safe concentration was identified, and the levels below the safe limit were tested at 72 hours and seven days for selected cytokines secretion. Results Majority of the tested Inflammatory cytokine secretion was reduced by the treatment of red rose extract on the cells. VEGF and angiogenic cytokine levels were reduced, but VEGF-R2 levels were maintained after the cell treatment. Below the safe concentration limit (0.5%) there were only minimal changes in the cytokines levels tested at various dilutions. Conclusion There is potential for a red rose extract treatment in the regulation of inflammatory cytokines secretion. Further studies need to be performed to identify the benefits.

Experiments on the internal stability of widely graded cohesionless soils
Creators: name: Moffat, Ricardo
Publisher: name: University of British Columbia
Year: 2009

description: Internal instability of widely-graded cohesionless soils results from an inability to prevent loss of the finer particles in the presence of forces induced by seepage flow and, on occasion, vibration. Instability is governed by a combination of geometrical and hydromechanical constraints, and therefore largely controlled by soil type and seepage regime. Performance monitoring of embankment dams suggests the phenomenon is an important factor in the overall stability of these structures. A large permeameter test device was designed and commissioned to perform unidirectional seepage flow tests on four widely-graded cohesionless soils, all of which are potentially unstable. The objective was to assess the main hydromechanical factors that influence the onset of instability. A modified slurry mixing technique, with discrete deposition, was found satisfactory for reconstitution of homogeneous saturated test specimens. Test variables examined include hydraulic gradient, rate of increase in hydraulic gradient, flow direction, and vertical effective stress. The onset of internal instability was found to be triggered either by an increase in hydraulic gradient, or by a decrease in vertical effective stress. The relation between effective stress and hydraulic gradient, where the onset of instability occurs, is used to characterise a hydromechanical constraint to internal stability. Each soil yielded a hydromechanical boundary, and the difference between them is attributed to the shape of the grain size distribution of the soil and to the variation of vertical effective stress in the direction of flow where suffosion initiated. A limit-equilibrium approach is used to explain the experimental findings on hydromechanical constraints, based on a geometrical characterization of the gradation curve and for an assumed distribution of effective stress between coarser and finer fraction particles of the soil. Analysis of the experimental data established that the hydromechanical boundary is not unique: it is governed by both the magnitude of vertical effective stress and the variation of that stress in the direction of flow.
Cash transfers, resilience and child labour in Ghana

description: This study examines the impacts of an unconditional cash transfer programme on cocoa-growing households in Ghana. The study was designed a randomized experiment and aimed to test whether cash transfers, implemented within a supply chain structure, can help reduce hazardous child labour, and what other impacts they have on children and their families in this context. The results show that the cash transfer reduced the likelihood of a child doing hazardous work in the past six months by 9.3 percentage points, which corresponded to a 16% reduction relative to the sample mean. The results also show that the cash transfer allowed households to build up wealth, measured through durable wealth items acquired during the cash payment period. Importantly, the cash transfer also made households more resilient to adverse shocks, such as sickness or unexpected losses of income. While adverse shocks were experienced by around two thirds of the households in both the control and the cash recipient groups, households that received cash transfers were less likely to reduce their food consumption as a consequence of the shock. Children benefitted in other ways too: their material wellbeing improved, as measured by the child's ownership of basic items such as a blanket and a second set of clothes. The cash transfers also protected children against adverse events. Among households that did not receive the cash transfer, child labour increased in the case of an adverse event. The results show that unconditional cash transfers paid to cocoa farmers within a supply chain structure in Ghana can help to prevent and address hazardous child labour. Notably, cash transfers can protect households and children against adverse shocks, such as sickness, bereavement in the family, income fluctuations or loss of agricultural production.

description: A non-Hermitian Hamiltonian has a real positive spectrum and exhibits unitary time evolution if the Hamiltonian possesses an unbroken PT (space-time reflection) symmetry. The proof of unitarity requires the construction of a linear operator called C. It is shown here that C is the complex extension of the intrinsic parity operator and that the C operator transforms under the Lorentz group as a scalar.

description: I briefly review cosmological bounds on neutrino masses and the underlying gravitational physics at a level appropriate for readers outside the field of cosmology. For the case of three massive neutrinos with standard model freezeout, the current 95% upper limit on the sum of their masses is 0.42 eV. I summarize the basic physical mechanism making matter clustering such a sensitive probe of massive neutrinos. I discuss the prospects of doing still better in coming years using tools such as lensing tomography, approaching a sensitivity around 0.03 eV. Since the lower bound from atmospheric neutrino oscillations is around 0.05 eV, upcoming cosmological measurements should detect neutrino mass if the technical and fiscal challenges can be met.

description: Purpose: The e!cacy of endovenous stenting for ileofemoral stenosis or occlusion in post-thrombotic syndrome (PTS) is gaining momentum with studies reporting improved clinical outcome. This study analyses the outcomes of venous stenting in PTS for patients in whom conservative and/or prior surgical treatment modalities had failed. Materials and Method: Operative and clinical records were retrospectively analysed in all patients who had endovenous stenting for PTS. Baseline demographics, procedural details and symptom severity based on CEAP and Villalta scores were collected. Stent patency was assessed by follow-up duplex ultrasound. Clinical follow-up included Villalta score and a subjective assessment of improvement. Results: Fifteen patients with a mean Villalta score of 11 were treated. Two were lost to follow-up. Technical success was 100% with no major complication. Two minor complications (self-limiting bleeding) occurred. At follow-up, stent patency, by Duplex ultrasound, was 71.4% at 13 (range 5–54) weeks. 53.8% (n=7) of patients reported subjective improvement in their symptoms, 30.8% (n=4) of patients reporting no improvement and 15.4% (n=2) of patients reporting worsening of their symptoms. The mean Villalta score at follow-up was 8.5; a signi"cant reduction (p=0.049) from the pre-procedural score. Conclusion: Endovenous stenting for PTS can be performed safely and with a high technical success rate. Patency rates are reasonable and are associated with a signi"cant reduction in Villalta scores.

description: The gapless color-flavor locked (gCFL) phase is the second-densest phase of matter in the QCD phase diagram, making it a plausible constituent of the core of neutron stars. We show that even a relatively small region of gCFL matter in a star will dominate both the heat capacity C_V and the heat loss by neutrino emission L_ν. The gCFL phase is characterized by an unusual quasiparticle dispersion relation that makes both its specific heat c_V and its neutrino emissivity epsilon_νparametrically larger than in any other phase of nuclear or quark matter. During the epoch in which the cooling of the star is dominated by direct Urca neutrino emission, the presence of a gCFL region does not strongly alter the cooling history because the enhancements of C_V and L_νcancel against each other. At late times, however, the cooling is dominated by photon emission from the surface, so L_νis irrelevant, and the anomalously large heat capacity of the gCFL region keeps the star warm. The temperature drops with time as T\sim t^{-1.4} rather than the canonical T\sim t^{-5}. This provides a unique and potentially observable signature of gCFL quark matter.
