Résumé :
I provide evidence on the existence of unspanned macro risk. I investigate the usefulness of unspanned macro information for forecasting bond risk premia in a macro-finance term structure model from the perspective of a bond investor. I account for model uncertainty by combining forecasts with and without unspanned output and inflation risks optimally from the forecaster’s objective. Incorporating macro information generates significant gains in forecasting bond risk premia relative to yield curve information at long forecast horizons, especially when allowing for time-varying combination weight. These gains in predictive accuracy significantly improve investor utility.

Résumé :
Bond behaviour of a synthetic macro-fibre in concrete is the object of this research. The bond strength and stiffness are the parameters characterising the bonding mechanism that determines the efficiency of the reinforcing material. However, there is no general methodology developed to evaluate fibre efficiency. There also exists neither a straightforward procedure to estimate the bond quality of a synthetic macro-fibre nor a reliable numerical model to simulate the bond behaviour of such fibres. In this work, the bond mechanisms of 40 mm long synthetic macro-fibres are investigated using pull-out tests: 16 concrete cubes were made for that purpose. One type of synthetic macro-fibre available at the market is considered. In each test sample, three fibres were inserted perpendicular to the top and two side surfaces; two bonding lengths (10 mm and 20 mm) were used. A gripping system was developed to protect the fibres from local damage. A physically non-linear finite element model of the pull-out sample was developed. A bond model was proposed to simulate deformation behaviour of the fibres.

Résumé :
Bone is porous and has a complex microstructure. This study considers the effect of microstructural morphology on the macrolevel mechanical properties of bone. Improved incorporation of such properties is required to advance current finite element approximations of bone behaviour. A technique to computationally generate realistic trabecular bone microstructures is developed. This provides the possibility of examining the effect of different microstructures on the macrolevel mechanical behaviour of bone. They would also permit direct incorporation of bone microstructure in macroscale finite element analyses without the prohibitive computational and experimental costs of donor-image based mesh generation. Micro- finite-element analyses are used for the first time to evaluate the macrolevel orthotropic elastic constants of cortical bone resulting from variations of microstructural morphology. It is concluded that the ratio of canal volume to tissue volume is the most powerful predictor of cortical bone elastic constants and that considerable periosteal-endosteal variations in these constants can develop with bone loss. The role of microstructure in cortical bone toughness is investigated using nano- finite-element analyses of murine cortical bone samples to simulate the initiation and propagation of microcracks. Results confirm the experimentally observed ability of canal and lacuna pores to act as stress raisers, thereby guiding the growth of microcracks. A novel and numerically efficient strain-based plasticity algorithm is presented which permits easy incorporation of strength anisotropy in finite element analyses of bone. The previously evaluated elastic properties of cortical bone are combined with the developed plasticity algorithm to conduct a detailed macro-finite-element investigation of external fixation of tibial midshaft fractures. Old patients are found to be at considerably higher risk of implant loosening under both unilateral and Ilizarov fixation, compared to younger patients.

Interactions between macroeconomic fundamentals and term structure of interest rates be stronger according to the way of changes in structure of worldwide economy. Combined macro-finance analysis determines the joint dynamics of term structure of interest rates and macroeconomic fundamentals. This thesis provides analysis of two existing macro-finance models and an original one. Parameter estimations for these three macro-finance term structure models are done for monthly Turkish data by use of an efficient recursive estimator Kalman filter. In spite of the small scale application the results are satisfactory except first model but with longer sets of macroeconomic variables and interest rate data models provide more encouraging results.

Résumé :
This doctoral thesis is a collection of four papers on the analysis of the term structure of interest rates with a focus at the intersection of macroeconomics and finance. "Risk in Macroeconomic Fundamentals and Bond Return Predictability" documents that factors related to risks underlying the macroeconomy such as expectations, uncertainty and downside (upside) macroeconomic risks are able to explain variation in bond risk premia. The information provided is found to be, to a large extent, unrelated to that contained in forward rates and current macroeconomic conditions. "Out-of-sample bond excess returns predictability" provides evidence that macroeconomic variables, risks in macroeconomic outcomes as well as the combination of these different sources of information are able to generate statistical as well as economic bond excess returns predictability in an out-of-sample setting. Results suggest that this finding is not driven by revisions in macroeconomic data. The term spread (yield curve slope) is largely used as an indicator of future economic activity. "Re-examining the predictive power of the yield curve with quantile regression" provides new evidence on the predictive ability of the term spread by studying the whole conditional distribution of GDP growth. "Modeling and forecasting the yield curve by extended Nelson-Siegel class of models: a quantile regression approach" deals with yield curve prediction. More flexible Nelson-Siegel models are found to provide better fitting to the data, even when penalizing for additional model complexity. For the forecasting exercise, quantile-based models are found to overcome all competitors.

Résumé :
Bone marrow oedema is a term used to define the appearance of regions of low signal on T1 weighted and high signal on T2 weighted fat-suppressed magnetic resonance images. The potential association between bone marrow oedema and prognosis in pathologies such as osteoarthritis is becoming increasingly recognised through clinical studies. A limited number of clinical studies have linked bone marrow oedema to altered bone density or altered bone marrow perfusion. The principal aims of this study were to investigate these findings in vitro, using the equine forelimb. The presence of bone marrow oedema within the equine forelimb was initially confirmed by undertaking magnetic resonance imaging scans. Bone samples were selected from 10 animals, 5 exhibiting the presence of bone marrow oedema-type abnormalities (BMOA) at the distal metacarpal. Raman microspectroscopy was used to determine the chemical composition of bone and projection radiography to provide a measure of bone density. Micro computed x-ray tomography was undertaken on a subset of three bone samples exhibiting BMOA. A second component of the study utilised contrast enhanced magnetic resonance imaging to enable comparison of perfusion to bone marrow with and without evidence of oedema. A saline flushing agent containing Evan’s blue was used so that subsequent sectioning of the bone would enable visualisation of the distribution of contrast agent as part of a histological examination of the oedematous region. An initial observation was that the majority of bone marrow oedema that was observed in the distal metacarpal appeared in a consistent location, namely the postero-inferior aspect of the bone, corresponding to the point of greatest load thereby suggesting a potential relationship to forces upon the joint. The principal observations were that there appears to be increased bone volume densities in those bone samples with evidence of bone marrow oedema. The Raman microspectroscopy did not demonstrate any statistically significant differences in the chemical composition of bone. Hence the overall impression is that bone marrow oedema is associated with a greater volume of bone, although of similar maturity and composition. There was limited evidence of increased perfusion (suggestive of increased vascularity and / or hyperpermeability) in those samples with bone marrow oedema. This work suggests that these particular bone marrow oedema lesions are associated with bone changes and potentially vascular changes although the aetiology is currently unclear. Further work is needed to determine the clinical significance and prognosis associated with these particular lesions, and whether these findings can be replicated for bone marrow oedema demonstrated at other anatomical locations.

Résumé :
In this thesis, I first investigate the relation between the aggregate unemployment rate and foreign direct investment (FDI) inflows and outflows. To study this relationship, I use a panel data set that contains 45 (developed and developing) countries observed from 1987 through 2008, and I employ Arellano and Bonds generalized methods of moments (ABGMM) estimation method for dynamic panel data. My results show that FDI inflows and outflows are not determinants of the aggregate unemployment rate. In addition, in line with macroeconomic theory, the previous level of aggregate unemployment has a positive impact on the current level of aggregate unemployment. Again, as macroeconomic theory suggests, my results show that per capita real gross domestic product (RGDP) has a negative effect on the current level of aggregate unemployment. Second, I study the long-run relationship between exports and per capita gross domestic product (instrumented by total population) using a panel data set of 51 countries from 1970 through 2008. To study this relationship, I employ the dynamic ordinary least squares (DOLS) estimation method. I find that the percentage of exports in nominal gross domestic products (GDP) is sensitive to changes in the populations of host countries and, hence, to the changes in their GDP. In addition, my results show that the agreement on trade related investment measures increased the percentage of exports in the nominal GDP of developed host countries more than it did in developing host countries.

Résumé :
Calcium Phosphate ceramics have been widely used in tissue engineering due to their excellent biocompatibility and biodegradability. In the physiological environment, they are able to gradually degrade, absorbed and promote bone growth. Ultimately, they are capable of replacing damaged bone with new tissue. However, their low mechanical properties limit calcium phosphate ceramics in load-bearing applications. To obtain sufficient mechanical properties as well as high biocompatibility is one of the main focuses in biomaterials research. Therefore, the current project focuses on the preparation and characterization of porous tri-calcium phosphate (TCP) ceramic scaffolds. Hydroxapatite (HA) was used as the raw material, and normal calcium phosphate bioglass was added to adjust the ratio between calcium and phosphate. It was found that when 20% bioglass was added to HA and sintered at 1400oC for 3 hours, the TCP scaffold was obtained and this was confirmed by X-ray diffraction (XRD) analysis. Test results have shown that by applying this method, TCP scaffolds have significantly higher compressive strength (9.98MPa) than those made via TCP powder (<3MPa). Moreover, in order to further increase the compressive strength of TCP scaffolds, the samples were then coated with bioglass. For normal bioglass coated TCP scaffold, compressive strength was 16.69±0.5MPa; the compressive strength for single layer mesoporous bioglass coated scaffolds was 15.03±0.63MPa. In addition, this project has also concentrated on sizes and shapes effects; it was found that the cylinder scaffolds have more mechanical property than the club ones. In addition, this project performed cell culture within scaffold to assess biocompatibility. The cells were well distributed in the scaffold, and the cytotoxicity test was performed by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di- phenytetrazoliumromide (MTT) assay. The Alkaline Phosphatase (Alp) activity of human bone marrow mesenchymal stem cell system (hBMSCs) seeded on scaffold expressed higher in vitro than that in the positive control groups in osteogenic medium, which indicated that the scaffolds were both osteoconductive and osteoinductive, showing potential value in bone tissue engineering.

Résumé :
Summary of the Thesis This thesis concerns the study of the Macro-Synthetic Fiber, with the main objective of analyzing the effect of fiber embedded length on interface bond properties regard to different concrete mix design parameters. In particular the effect of different fiber embedded length, Water-Cement ratio (W/C), Cement-Sand ratio (C/S) and Cement strength on interfacial bond properties will be studied. The research is carried on by means of experimental direct pull-out tests on crimped macro-synthetic fibers embedded for two different lengths in a cementitious matrix characterized by different mix design. The experimental program employed is a part of a bigger experimental campaign on macro fiber reinforced concrete behavior which is under investigation at the University of Bologna. This experimental campaign was done to contribute the overall understanding of the fiber reinforced concrete, with the main goal of the calibration of a constitutive debonding law through numerical model and codification of fiber reinforced concrete in future, which is discussed in details in 5 Chapters in this study.

Texte intégral
Résumé :
The trend for designing of a titanium implant explored using different chemical compositions and crystallinity materials until people realized that the implant surface character was another important factor affecting the rate and extent of osseointegartion. Titanium received a macroporous titania surface layer by anodization, which contains open pores with average pore diameter around 5μm. An additional mesoporous titania top layer was created that followed the contour of the macropores and having 100–200 nm thickness and a pore diameter of 10 nm. Thus, a coherent laminar titania surface layer was obtained producing a hierarchical macro- and mesoporous surface. The interfacial bonding between the surface layers and the titanium matrix was characterized by a scratch test that confirmed a stable and strong bonding of the laminar titania surface layers upon titanium. The wettability to water and the effects on the osteosarcoma cell line (SaOS-2) proliferation and mineralization of the formed titania surface layers were studied systematically by cell culture and scanning electron microscopy (SEM). A synergistic role of the hierarchical macro- and mesoporosities was revealed in terms of enhancing cell adhesion, proliferation and mineralization, when compared with the titania surface with solo porosity scale topography. For the in vivo results of the evaluation of osseointegration, an argon ion beam polishing technique was applied to prepare the cross sections of implants feasible for the high resolution SEM investigation. The interfacial microstructure between newly formed bone and implants with four modified surfaces including the new hierarchical macro- and mesoporous implant surface retrieved after in vivo tests were characterized. By this approach it has become possible to directly observe early bone formation, the increase of bone density, and the evolution of bone structure. The two bone growth mechanisms, distant osteogenesis and contact osteogenesis, can also be distinguished. These direct observations give, at microscopic level, a better view of osseointegration and explain the functional mechanisms of various implant surfaces for osseointegration.

Résumé :
From the childfree and childless who nurture their dogs and cats similarly to a child to the grandparents who support them to children who view their animals as siblings and empty nesters who think of themselves as caretakers, it is clear that family structure—and who is part of that—has increasingly diversified in the United States since the 1970s. This book explores the ways in which family has changed to include companion animals as bona fide members with distinctly human identities. Using identity theory and the second demographic transition as a foundation, the author uses mixed methods to analyze thirty-five original in-depth interviews and over one hundred hours of fieldwork to show how the modern multispecies family has moved from thinking of companion animals as family entertainment to embracing them as genuine family members with needs and desires to be considered alongside other, human members of the family. The author also shows that the multispecies family has transcended from micro-level perceptions of kinship to macro-level, cultural shifts that acknowledge it as a legitimate family form. Content analysis of print advertisements reveals how the $72 billion pet-product industry has reproduced and reinforced the multispecies family as one with distinct needs, challenges, and relationships. The book underscores the necessity for mainstream family scholarship to take up the multispecies family as a new, nontraditional family type that has evolved in the same historical context as single-parent families, grandparent families, and cohabitation while encouraging identity theory to move beyond anthropocentric paradigms.

Résumé :
AbstractIn this study, hydrodynamics and heat transport during the impact of single and multiple drops onto a hot wall are studied numerically. The heat transfer in the vicinity of the three-phase contact line, where solid, liquid and vapour meet, contributes significantly to the global heat transfer. The microscale processes in the region of the three-phase contact line are analysed using a lubrication approximation. The results in the form of correlations are integrated into an overall model. The impingement of drops on a macro scale is simulated using a numerical model developed within the OpenFOAM library. The influence of dimensionless parameters, i.e., the Reynolds, Weber, Bond, Prandtl and Jakob numbers, as well as the influence of pressure, on the transport phenomena is discussed. The analysis of the influence of drop frequency and substrate thickness during the vertical coalescence and the influence of the drop spacing during the horizontal coalescence of drops on the hot surface complete the study. The results contribute to a better understanding of the complex mechanisms of spray cooling.

Résumé :
Abstract In this work we suggest a mechanism whereby the bone deformation driven flow of bone fluid through the glycocalyx surrounding an osteocytic cell process in its canaliculus will lead to strains in the cell process membrane which are many times those in the whole bone. We shall describe a mechanism whereby the low magnitude of the strain applied to the whole bone (0.1% to 0.3%) is amplified by nearly two orders of magnitude at the membrane of the cell process. The possibility of this strain amplification depends upon the values of the certain physical and biological parameters. These parameters include the elastic constants of the cell membrane, the elastic constants of the fibers that constitute the glycocalyx. the pre-tension in the fibers and cell membrane, the permeability of bone fluid through the glycocalyx, the physical dimensions of the cell process, the canaliculus, the fibers and fiber spacing of the glycocalyx. The model employed is an interactive micro-macro mechanical model. It was analyzed numerically. The micro model is a detailed model of the structure and contents of a canaliculus and the macro model is poroelasticity. A mechanical loading range from 1 MPa to 20 MPa at different frequencies, 1Hz to 20Hz, were considered. We calculated the ratio of the drag force on the fibers to the shear force on the osteocyte membrane in a canaliculus and found that the drag force is at least 50 times larger than the shear on the cell membrane. We also calculated the strain al the membrane, as well as the strain amplification ratio, and found that the strain amplification ratio reached a maximum value of 65 for this loading range. Thus the proposed mechanism amplifies the strain applied to the whole bone when it is experienced at the osteocyte process membrane.

Résumé :
As follow-up to recent papers by Marshall et al. (2010, 2012), research on steel-concrete-steel (SCS) sandwich shells for Arctic offshore structures continues at two universities. National University of Singapore is testing heavy transverse reinforcement which ties the outer steel plates together. Lamar University in Texas originally studied the composite ice wall concept in the late 1980s, and is now testing surface treatment with a size-tiered gradation of mini-studs, macro fibers (steel) and micro fibers (synthetic), intended to develop the full bulk properties of the Fiber Reinforced Concrete (FRC) core in radial tension and punching shear. Using ISO’s design non-hydrostatic partial span loading on the Singapore Cone, radial bond stress at the inner steel plate is low and deemed attainable for both the stud enhanced bonding surface and the bulk concrete core. The steel shell serves as prefabricated permanent formwork, and the arched vaults resist external ice loading mainly by compression, provided the sandwich does not disintegrate in an unstable fashion.

Résumé :
Existing data base and correlations in literature on the micro-channel pressure drop and heat transfer are reviewed. None of the existing correlations can cover the wide range of working fluids, operational conditions and different microchannel dimensions. The importance of the Bond number, which relates the nominal bubble dimension or capillary parameter with the channel size, is revealed. Using the Bond number, improved correlations of pressure drop and heat transfer are established. The new correlations predict the existing data well over wide ranges of working fluids, operational conditions and dimensions of micro-channels. Furthermore, Bond number could be used as a criterion to classify a flow path as a micro-channel or conventional macro-channel.

Résumé :
Previous experimental studies of cortical bone have investigated cortical bone fracture toughness and crack trajectory as a function of microstructural alignment of osteons [1,2]. The dependence of osteon orientation on screw pullout force and crack propagation trajectory during screw pullout has been demonstrated previously by Feerick and McGarry (2012) [3]. The alternate failure modes for longitudinal and transverse screw pullout observed in the latter study are shown in Figure 1. Using an isotropic damage criterion with crack growth was simulated using an element deletion technique. An explicit representation of cortical bone microstructure was required to replicate experimental observations. The use of such a computational scheme for 3D macro-scale applications is not viable given the requirement of explicit representation of the microstructure. Other computational studies of cortical bone have also developed geometric representations of the microstructure of cortical bone to simulate the fracture and establish crack trajectories [4]. Again, upscaling these detailed microstructural geometries in 3D macroscale simulations of fracture would currently be computationally unfeasible.
