description: A fundamental choice in femtocell deployments is the set of users which are allowed to access each femtocell. Closed access restricts the set to specifically registered users, while open access allows any mobile subscriber to use any femtocell. Which one is preferable depends strongly on the distance between the macrocell base station (MBS) and femtocell. The main results of the paper are lemmas which provide expressions for the SINR distribution for various zones within a cell as a function of this MBS-femto distance. The average sum throughput (or any other SINR-based metric) of home users and cellular users under open and closed access can be readily determined from these expressions. We show that unlike in the uplink, the interests of home and cellular users are in conflict, with home users preferring closed access and cellular users preferring open access. The conflict is most pronounced for femtocells near the cell edge, when there are many cellular users and fewer femtocells. To mitigate this conflict, we propose a middle way which we term shared access in which femtocells allocate an adjustable number of time-slots between home and cellular users such that a specified minimum rate for each can be achieved. The optimal such sharing fraction is derived. Analysis shows that shared access achieves at least the overall throughput of open access while also satisfying rate requirements, while closed access fails for cellular users and open access fails for the home user.

description: We present a detailed analysis comparing the velocity fields in molecular clouds and the atomic gas that surrounds them in order to address the origin of the gradients. To that end, we present first-moment intensity-weighted velocity maps of the molecular clouds and surrounding atomic gas. The maps are made from high-resolution 13CO observations and 21-cm observations from the Leiden/Argentine/Bonn Galactic HI Survey. We find that (i) the atomic gas associated with each molecular cloud has a substantial velocity gradient---ranging within 0.02 to 0.07 km/s/pc---whether or not the molecular cloud itself has a substantial linear gradient (ii) If the gradients in the molecular and atomic gas were due to rotation, this would imply that the molecular clouds have less specific angular momentum than the surrounding HI by a factor of 1-6. (iii) Most importantly, the velocity gradient position angles in the molecular and atomic gas are generally widely separated---by as much as 130 degrees in the case of the Rosette Molecular Cloud. This result argues against the hypothesis that molecular clouds formed by simple top-down collapse from atomic gas.

description: We describe a general mechanism of controllable energy exchange between waves propagating in a dynamic artificial crystal. We show that if a spatial periodicity is temporarily imposed on the transmission properties of a wave-carrying medium whilst a wave is inside, this wave is coupled to a secondary counter-propagating wave and energy oscillates between the two. The oscillation frequency is determined by the width of the spectral band gap created by the periodicity and the frequency difference between the coupled waves. The effect is demonstrated with spin waves in a dynamic magnonic crystal.

Failure mechanism of rolling shear failure in cross-laminated timber
Creators: name: Nie, Xin
Publisher: name: University of British Columbia
Year: 2015

description: Wood as building material is gaining more and more attention in the 21st century due to its positive attributes such as light weight, renewability, low carbon footprint and fast construction period. Cross-laminated timber (CLT), as one of the new engineered wood products, requires more research emphasis since its mechanical performance can allow CLT to be utilized in massive timber structures. This thesis focuses on revealing one of the key failure mechanisms of CLT, which is usually referred to as the rolling shear failure. The scientific research conducted in this thesis combined both analytical modelling and experimental material testing. The stresses in CLT cross-layers obtained from a finite-element model were analyzed to differentiate various failure modes possible. Tension perpendicular to grain stress was found to cause cross-layer failure in combined with the rolling shear stress. Experimentally, specimens prepared from 5-layer CLT panels were tested under center-point bending condition. Detailed failure mechanism of CLT cross-layers were recorded with high speed camera to capture the instant when initial failure happened. It is evident that some of the specimens failed in tension perpendicular to grain which verified the modelling results. Variables such as the rate of loading and the manufacturing clamping pressure were designed in experiments to compare their influence to the failure of CLT specimens. In this research, the failure of CLT cross-layer was updated to a combined consequence of both rolling shear stress and tension perpendicular to grain stress. Future research topics and product improvement potentials were given by the end of this thesis.

City stories : from narrative to practice in Vancouver's Olympic Village
Creators: name: Westerhoff, Lisa Michelle
Publisher: name: University of British Columbia
Year: 2015

description: Calls for a more thoughtful and wholehearted inclusion of the humanities and social sciences in defining and answering questions of sustainability have highlighted the importance of integrating a more comprehensive range of values, knowledges and perspectives into our efforts to transition towards sustainable societies. Far from an abstract gesture, such a shift has practical implications for the way sustainability policies and projects are conceived and carried out, including the design and assessment of urban sustainable neighbourhoods. In this dissertation, I show that the study of narrative offers a potent means of untangling the underlying assumptions and meanings embedded within decisions and characterizations of sustainability and sustainable neighbourhoods, which I explore in the context of Vancouver’s Olympic Village. I tell the story of this unique urban development from the perspectives of the many voices that have created it, from its first planners to its present beneficiaries. By combining narrative with insights and methods from social practice theories, I show how the sustainable intentions of the Olympic Village have challenged and intersected with the lived narratives of its residents and managers, two key constituencies in the neighbourhood’s unfolding. I investigate the neighbourhood as an intervention both structural and symbolic to reveal the normative (i.e. discursive) and performative (i.e. material) dimensions of the neighbourhood’s particular narrative of sustainability, and the way these have intervened into residents’ and managers’ practices, perceptions and identities. I conclude that while broad metanarratives of sustainability in both policy and media have played strong roles in shaping the lives of the neighbourhood’s residents and managers, the neighbourhood continues to evolve as its constituents perform new practices in the landscape. I show the important intersection between social and ecological goals, highlighting the need to consider and support liveability in the pursuit of sustainability. Finally, I show that while the neighbourhood has been instrumental in pushing sustainability efforts forward, it also missed key opportunities to address the expectations and experiences of its future inhabitants.

description: One-way functions are widely used for encrypting the secret in public key cryptography, although they are regarded as plausibly one-way but have not been proven so. Here we discuss the public key cryptosystem based on the system of higher order Diophantine equations. In this system those Diophantine equations are used as public keys for sender and recipient, and sender can recover the secret from the Diophantine equation returned from recipient with a trapdoor. In general the system of Diophantine equations is hard to solve when it is positive-dimensional and it implies the Diophantine equations in this cryptosystem works as a possible one-way function. We also discuss some problems on implementation, which are caused from additional complexity necessary for constructing Diophantine equations in order to prevent from attacking by tamperers.

description: The Large Hadron Collider (LHC) experiments have revealed that the predictions of the color glass condensate (CGC) tend to underestimate the multiplicity at mid-rapidity. We develop and estimate a full second-order viscous hydrodynamic model for the longitudinal expansion to find that the CGC rapidity distributions are visibly deformed during the hydrodynamic stage due to the interplay between the entropy production and the entropy flux to forward rapidity. The results indicate the importance of viscous hydrodynamic evolution with non-boost invariant flow for understanding the CGC in terms of the heavy ion collisions.

The potential role of MMP2 in the response of tendons to mechanical stimulation
Creators: name: Huisman, Elise Suzanne
Publisher: name: University of British Columbia
Year: 2016

description: Tendinopathy is a common problem in the population leaving people in pain, unable to work or be physically active. High levels of musculotendinous strain (resulting from heavy lifting or obesity) and repetitive movements are risk factors for tendinopathy. Because MMPs and TIMPs play a crucial role in the repair, remodeling, and degeneration of collagen fibers in tendon, the aim of this dissertation was to identify the potential roles of MMPs, TIMPs and collagens type I and III, using in-vitro and in-vivo models of overuse and repair. Having identified a potential role of MMP2 in these laboratory models, a clinical study was also conducted to evaluate the serum levels of MMPs and TIMPs in patients who had experienced Achilles tendon rupture. Cultured tendon cells, controlled by high frequency or high strain stimulation, simulating overuse, increased MMP2 mRNA expression. Collagen type I mRNA and protein levels were increased in cultured tendon cells by controlled mechanical stimulation with intermittent rest periods compared to continuous mechanical stimulation. In both the normal healthy rabbit and an overuse model of the rabbits’ Achilles tendon, regional differences in mRNA expression and histological structure were observed. After two weeks of repetitive tendon loading, collagen intensity, measured by second harmonic generation microscopy, was decreased in the flexor digitorum superficialis (FDS) tendon compared to the contralateral FDS tendon and healthy control FDS tendon, indicating damage or remodelling of the collagen in response to overuse. Structural changes were observed locally, combined with elevated tissue MMP2 protein levels suggesting a possible contribution of MMP2 to the development of early collagen degradation. MMP2 appears to play a role early in the response of tendon to repetitive loading. It is detectable in serum after 1 week of overuse, and high repetition number and high strain level are independent modulators of MMP2 expression in tenocytes. However, MMP2 levels in serum decline to baseline after 2 weeks in the animal model, and were downregulated compared to controls in patients with a more Achilles tendon rupture. Further research into the specific processes of tendon injury and repair played by MMP2 are warranted.

Analysing the empirical time complexity of high-performance algorithms for SAT and TSP
Creators: name: Mu, Zongxu
Publisher: name: University of British Columbia
Year: 2015

description: The time complexity of problems and algorithms, i.e., the scaling of the time required for solving a problem instance as a function of instance size, is of key interest in theoretical computer science and practical applications. In this context, the propositional satisfiability (SAT) and the travelling salesperson (TSP) are two of the most intensely studied problems, and it is generally believed that solving SAT or TSP requires exponential time in the worst case. In this work, we refine and extend a recent empirical scaling analysis approach and study the empirical scaling of the running times of several prominent, high-performance SAT and TSP algorithms. For SAT, we focus on random 3-SAT instances from the phase transition region, arguably the most prominent model for difficult SAT instances, and obtain interesting and surprising scaling results for both SLS- and DPLL-based solvers. Particularly, we find solid support for polynomial scaling for SLS-based solvers on phase-transition random 3-SAT instances. We also show that DPLL-based solvers scale exponentially and are faster by only a constant factor in solving satisfiable instances compared to unsatisfiable instances. We further report empirical scaling results for two classes of random 4-SAT instances to gain additional insights into the performance of state-of-the-art SAT solvers. For TSP, we concentrate on two-dimensional random uniform Euclidean (RUE) instances, and characterise the scaling of running time for complete and incomplete algorithms for finding optimal solutions. Our results indicate that the scaling of all these algorithms is consistent with or bounded from above by root-exponential models of the form a·b^(√n). We also explored the impact of automated algorithm configuration on the scaling of these algorithms. Since our approach is applicable beyond SAT and TSP, to enable its broad use, we designed Empirical Scaling Analyser (ESA), an automated tool that can be conveniently used to study empirical scaling of many types of algorithms. In particular, ESA presents scaling analysis results in the form of automatically generated, detailed technical reports. Many results reported in this thesis, including most tables and figures, were automatically generated by ESA and are only slightly modified to fit here.

description: Theories of dark matter that support bound states are an intriguing possibility for the identity of the missing mass of the Universe. This article proposes a class of models of supersymmetric composite dark matter where the interactions with the Standard Model communicate supersymmetry breaking to the dark sector. In these models supersymmetry breaking can be treated as a perturbation on the spectrum of bound states. Using a general formalism, the spectrum with leading supersymmetry effects is computed without specifying the details of the binding dynamics. The interactions of the composite states with the Standard Model are computed and several benchmark models are described. General features of non-relativistic supersymmetric bound states are emphasized.

description: Defect chemistry is key to understand electrical properties of many functional materials including halide perovskites. However, expectations from defect chemistry about the dependency of defect densities on the doping regime of halide perovskites have not yet been clearly confirmed experimentally. Here, we measure the electrical conductivity of the model halide perovskite Methylammonium Lead Iodide over a wide range of iodine partial pressures. We find that with iodine partial pressure the electrical conductivity changes with different slopes in a double-logarithmic representation, indicating changes of the perovskite conductivity mechanism. Considering differences in the mobilities of the various defect species, we derive expectations about the dependence of the total conductivity of the perovskite as a function of iodine partial pressure. We find iodine vacancies dominating the conductivity at low iodine partial pressures, whereas at higher partial pressures holes govern the total conductivity. We find the concentration of iodide vacancies to be ∼1018 cm−3, in good agreement with the expected values based on intrinsic ionic disorder. Finally, for the case that the intrinsic ionic disorder concentration is overestimated, we elucidate the possibility to explain the conductivity profile by impurity induced acceptor doping in the perovskite. Thus, our work will allow to develop a more fundamental understanding about the electrical properties of halide perovskites.
Impact of prior hysterectomy on risk of subsequent back injury in front line healthcare workers
Creators: name: Lochhead, Lois Edna
Publisher: name: University of British Columbia
Year: 2015

description: Low back injury (LBI) is associated with altered core muscle function and studies have validated the role of these deep stabilizing muscles in prevention and treatment of back pain and injury. No previous studies have evaluated the impact of surgery such as abdominal hysterectomy (AH) on these deep stabilizers and the potential for increased risk of LBI following surgery. The aims of this research were to investigate a link between AH and LBI first with administrative health data analysis and then clinically by measuring muscle thickness with rehabilitation ultrasound imaging (RUSI) before and after surgery. A retrospective cohort of 37,057 female frontline healthcare workers, a population at high risk of occupational LBI due to the heavy nature of their work, was extracted. Exclusion of 27,987 due to a history of back pain or injury, prior hysterectomy or failure to meet the provincial residency requirement of five years left a sample size of 9,070. Within this research sample, 634 (7%) had undergone hysterectomy, a prevalence much lower than the published value of 30%. Statistical analysis revealed no increased risk of LBI in this cohort of healthcare workers without prior history of LBI. Clinical RUSI assessment of the core muscles would investigate if this was because there was no change in the muscle function post-surgically. Validity and reliability of RUSI to evaluate core muscle function have been established for intersessions up to two weeks. A group of women not undergoing AH was used to establish reliability over intervals of four, eight and twelve weeks. Intraclass correlations (ICC₃,₁) ranging from 0.75 to 0.90 for measured muscle thickness in the deep abdominal and lumbar muscles exceeded the minimum standard of 0.70 for research purposes. Percent change measures did not meet this standard. A prospective descriptive case series involving nine individuals undergoing AH found post-surgical decreases in measurements of the deep abdominal stabilizers most notably in the participants with a history of previous low back pain/injury or who were obese. These findings support continued investigation of the relationship between AH and LBI including individuals with risk factors such as prior low back pain/injury and/or obesity.
On signal and extraneous roots in Singular Spectrum Analysis

Year: 2010
Subjects: subject: Methodology (stat.ME)

description: In the present paper we study properties of roots of characteristic polynomials for the linear recurrent formulae (LRF) that govern time series. We also investigate how the values of these roots affect Singular Spectrum Analysis implications, in what concerns separation of components, SSA forecasting and related signal parameter estimation methods. The roots of the characteristic polynomial for an LRF comprise the signal roots, which determine the structure of the time series, and extraneous roots. We show how the separability of two time series can be characterized in terms of their signal roots. All possible cases of exact separability are enumerated. We also examine properties of extraneous roots of the LRF used in SSA forecasting algorithms, which is equivalent to the Min-Norm vector in subspace-based estimation methods. We apply recent theoretical results for orthogonal polynomials on the unit circle, which enable us to precisely describe the asymptotic distribution of extraneous roots relative to the position of the signal roots.

Energy in place : a case study and mental models analysis of engagement in community scale energy planning
Creators: name: Salter, Jonathan
Publisher: name: University of British Columbia
Year: 2015

description: This dissertation has two primary research threads. The first is a case study analysis of three community scale energy planning engagement processes in British Columbia, including community energy and greenhouse gas emissions workshops conducted in the City of Vancouver as part of the Greenest City Conversations Project (GCCP), stakeholder workshops as part of the City of Victoria’s Community Energy and Emissions Plan (CEEP), and public workshops conducted in the City of Revelstoke that investigated the relationships between urban form, energy, and climate change. The second research thread investigates the use of a mental models methodology for evaluating the impacts of engagement on the workshop participants. The research first examines the literature on public engagement in sustainability planning, and the literature on mental models methodologies, developing the rationale for a mental models approach to evaluating engagement in community scale energy planning. The research then turns to the development and conduct of the mental models methodology, starting with initial practitioner interviews to describe the community scale energy domain. These interviews revealed key themes about energy and related subjects that contributed to both the GCCP workshop development, and the construction of the dissertation’s primary research instrument, the pre and post workshop questionnaires. Workshop participants existing mental models of energy are then analyzed based on the results of the pre-workshop questionnaires, using a Multiple Correspondence Analysis (MCA) and hierarchical clustering procedure. This analysis revealed the presence of six primary clusters of energy mental models amongst participants that were used to organize and interpret subsequent research results. The final phase of the research combines a case study and mental models evaluation of the three community energy engagement processes, beginning with the dissertation’s primary research vehicle (the GCCP workshops) and then comparing the three engagement processes for their impacts on participants’ mental models, and for the constituent case study components that defined the workshops. The final chapter then turns to a discussion of the implications of the research for future mental models, energy planning, and public engagement research and practice.

description: Apoiado em dados empíricos e bibliográficos, este texto observa, de forma comparativa, os processos de consagração e movimentos devocionais em torno do Dr. Sousa Martins em Portugal, de Maria da Conceição (Santa da Ladeira) em Portugal e de São João Maria no Brasil. Estas três figuras foram reconhecidas por seus devotos como pessoas boas, curadores milagrosos e dedicados ao povo, especialmente pobre, e são estas características que comporão, posteriormente, os elementos de sua venerabilidade. Sua não canonização institucional não impediu que o movimento devocional em torno deles fosse expressivo e cruzasse fronteiras denominacionais, etárias, territoriais, de género, e situação sócio-económica. Estes movimentos aproximam-se mais de práticas da religiosidade “popular”, pois são marcados pela espontaneidade, criatividade, participação ampla das pessoas, festividade, dinamicidade e ênfase maior em valores sociais e culturais do que propriamente religiosos.

description: The article looks at the challenges and opportunities of collecting and disseminating performance art from an art library’s perspective. Based on the collecting experience of the Mediathek at the Academy of Art and Design FHNW Basel (Switzerland), the text contextualizes the own digital collections within the Swiss performance art context. What is special about Mediathek’s collection is 1) the fact that a remarkable number of documents of performance art are accessible for free via the internet, without login, in a structured, searchable and sustainable way. Because the policy permits, upon certain conditions, the acceptance of content from individuals, groups, and institutions not associated with the university, there is 2) a considerable amount of ‘external’ materials in the collections. The aim of the essay is to make this treasure of sources known. Therefore, digital access points to the projects and collections described in the text are mentioned in the references.

description: Este texto constitui uma abordagem historiográfica e diacrónica a um movimento devocional desencadeado pela comunicação de uma revelação, em sonhos, por parte de um agricultor do Norte de Portugal aos seus vizinhos, no Verão de 1924. Nos seus primeiros anos, e antes que se consagrasse como um santuário e uma romaria anual legítimos, este movimento desencadeou um conjunto de acontecimentos dignos de registo e refletores do contexto histórico daqueles últimos anos da I República. Entre outros aspetos, abordam-se: os conflitos entre a população local e as autoridades eclesiásticas em torno da legitimação e do controlo do santuário e da romaria; o envolvimento das autoridades eclesiásticas, civis e judiciais; a influência de outros casos de religiosidade popular; alguns fenómenos de sincretismo religioso; e a importância da imprensa como palco de publicitação e debate.

description: Slow rotation and absence of strong mixing processes in atmospheres of chemically peculiar stars develop ideal conditions for the appearance of abundance anomalies through the mechanism of microscopic particle diffusion. This makes these objects look spectroscopically and photometrically different from their "normal" analogs. As a result, it is often difficult to accurately determine atmospheric parameters of these stars and special methods are needed for the consistent analysis of their atmospheres. The main aim of the present paper is to analyse atmospheric abundance and stratification of chemical elements in the atmosphere of the chemically peculiar star HD 103498. We find that two model atmospheres computed with individual and stratified abundances provide reasonable fit to observed spectroscopic and photometric indicators: Teff=9300 K, logg=3.5 and Teff=9500K, logg=3.6. It is shown that Mg has a large abundance gradient in the star's atmosphere with accumulation of Mg ions in the uppermost atmospheric layers, whereas Si demonstrates opposite behaviour with accumulation in deep layers. In addition, a detailed non-LTE analysis showed that none of Mg transitions under consideration is a subject of noticeable non-LTE effects. Comparing observed photometry transformed to physical units we estimated the radius of HD 103498 to be between R=(4.56 +/- 0.77)Rsun for Teff=9300K, logg=3.5 and R=(4.39 +/- 0.75)Rsun for Teff=9500K, logg=3.6 models respectively. We note that the lack of suitable observations in absolute units prevents us to uniquely determine the Teff of the star at the current stage of analysis.

description: A presente nota de investigação atenta na última edição de 2006 de History and Theory, revista científica norte-americana publicada pela Wesleyan University. Este título, debruçando-se desde 1960 sobre os domínios da Filosofia, Teoria e Metodologia da História, foi no seu quadragésimo quinto número temático integralmente dedicado à reflexão acerca da relação entre Religião e História, com particular enfoque sobre os pressupostos epistemológicos que, de acordo com diferentes formulações, escoram o trabalho de investigação contemporâneo. É apresentada uma breve síntese crítica do volume, composto por nove ensaios (David Shaw; Constantin Fasolt; Mark Cladis; C.T. McIntire; David White; Brad Gregory; Jon Butler; Catherine Bell; James Ketelaar) nos quais são propostos diferentes figurinos teóricos destinados à superação das limitações identificadas na presente abordagem historiográfica ao fenómeno religioso.

Radio frequency switch mode power amplifiers and synchronous rectifiers for wireless applications
Creators: name: Abbasian, Sadegh
Publisher: name: University of British Columbia
Year: 2015

description: This thesis focuses on identifying and evaluating device, circuit, and system level issues that affect the power efficiency of class-D and class-F switch-mode amplifiers, and class-F synchronous rectifiers. The amplifier and rectifier circuits are used to implement pulse encoded switch-mode power amplifier systems. A detailed power efficiency analysis of current mode class-D amplifiers is presented for variable duty cycle pulse trains. A device model with current saturation in the switch is introduced and gives insight into how to select an appropriate load line for variable duty cycle switching conditions. Other new results include the effect of capacitive switching losses which are usually neglected in current mode amplifiers. The analytical results are compared with simulation results and confirm that the model can provide good predictions of power efficiency for a more general class of pulse encoded signals. Class-F amplifiers are also investigated in this work. The work investigates how input harmonic matching impedances at the gate affect amplifier power efficiency. Second harmonic matching is very important and desensitizes the circuit to nonlinear capacitances in the device. Third harmonic input terminations are much less significant. A comparison of voltage and current mode circuits is also made and the current mode is better in terms of maximizing power efficiency. The work is supported by experimental results. Class-F amplifier circuits are reconfigured into synchronous rectifiers using the theory of time-reversal duality. Time-reversal duality is usually applied in the context of lossless circuits and a discussion of how loss impacts the circuit duals is presented. The rectifier dual always has slightly higher power efficiency and insights into why this occurs are described. Experimental results are shown for voltage and current mode class-F rectifiers as well as a wideband current mode class-F rectifier. The thesis concludes with the analysis and experimental results for an energy recycling switch-mode power amplifier. A signal splitting network is implemented at the output of the amplifier and out-of-band power is rectified to enhance the power efficiency of the amplifier. Experimental results confirm that energy recycling can increase power efficiency. Concluding remarks based on this research are summarized in the context of how best to use these circuits for implementing high efficiency amplifiers and rectifiers for wireless applications.

Open MRI investigation of contact mechanics in cam femoroacetabular impingement
Creators: name: Buchan, Lawrence Lewis
Publisher: name: University of British Columbia

description: Cam femoroacetabular impingement (FAI) is a mechanical process thought to cause of hip osteoarthritis (OA). In cam FAI, it is thought that a ‘cam deformity’ on the femoral head-neck junction intrudes into the intra-articular joint space, inducing elevated mechanical force on acetabular cartilage. However, few experimental studies have measured contact mechanics in FAI. Open MRI in functional positions has potential to directly and non-invasively assess cam FAI, but MRI measures have not been related to mechanics. This thesis asked, in cadaver hips positioned in a simulated anterior impingement posture: (1) Does open MRI show intrusion of a cam deformity into the intra-articular joint space? (2) Is a cam deformity associated with elevated acetabular contact force? (3) Are MRI measures of cam FAI related to acetabular contact force? Cadaver hips (cam, n=9; controls, n=3) were positioned in a simulated anterior impingement posture, then imaged using open MRI with multi-planar reformatting. The β-angle was measured at 72 locations about the circumference of the femoral neck, and a binary ‘MRI cam-intrusion sign’ was defined (positive if βmin<0°). Hips were then instrumented with a piezoresistive sensor before conducting six repeated impingement trials, measuring acetabular contact force (F), centroid location, and distribution. A binary ‘contact-force sign’ (positive when F>20N) defined elevated contact force. Minimum β-angle ranged from 1.4° to -28.5° in cams versus 4.6° to -0.2° in controls. Cam hips were significantly more likely than controls to have a positive MRI cam-intrusion sign (p=0.0182, Fisher’s exact test) and positive contact-force sign (p=0.0083). There was a significant relationship between the MRI cam-intrusion sign and contact-force sign (p=0.033). This thesis established that open MRI measures of cam FAI relate to contact mechanics, indicating that open MRI has significant potential to investigate the biomechanics of cam impingement. Open MRI can be used to establish treatment guidelines and understand why some hips develop OA and some do not.

Os Vencidos do Catolicismo: do poema de Ruy Belo, Nós os vencidos do catolicismo (1970), ao problema do “vencidismo” católico
Creators: name: Revez, Jorge
Publisher: name: Lusitania Sacra
Year: 2007

description: Partindo de um poema de Ruy Belo (1933-1978) e do seu contexto histórico, este artigo procura, de forma preliminar, analisar e compreender as atitudes críticas de um conjunto de católicos face à Igreja durante as décadas de 60 e 70. Refere algumas destas tomadas de posição, focando principalmente a figura de Ruy Belo, caso paradigmático do criticismo e conflito que marcaram a relação entre alguns sectores da militância católica e a hierarquia eclesiástica, com todas as dimensões institucionais que esta representava. A construção da ideia de “vencidismo católico”, que o seu poema fez emergir é confrontada com conceitos como secularização e pós-catolicismo, no sentido de se tentar avaliar o impacto desta dinâmica na recomposição do campo católico em Portugal.
