Abstract:

Relapsed acute lymphoblastic leukaemia (ALL), diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) comprise a group of malignancies with poor prognosis and therapeutic strategies are needed to improve outcomes. Recent studies have shown that heterozygous inactivating mutations in the histone acetyl transferase, CREBBP, are frequent in these malignancies, and are thought to lead to impaired transcription of glucocorticoid (GC) response genes. Given the pivotal role of GC in the treatment of lymphoid malignancies and the finding that CREBBP mutations often arise at relapse, it has

Abstract:

Non-Hodgkin’s lymphomas (NHL) are a spectrum of hematopoietic cancer accounting for 4% of new cancer diagnoses each year. Approximately 95% of all NHL are of B-cell origin; diffuse large B-cell lymphomas (DLBCL) and follicular lymphoma (FL) accounting for 30-40% and 20% of B-NHL respectively. Recent human mutation profiling and resequencing studies have shown that CREBBP and BCL2 are frequently mutated, early events in B-NHL that are often are concurrent. This thesis presents a study of their role in oncogenesis by generating a novel model of B-NHL overexpressing BCL2 in the haematopoetic comp

Rubinstein–Taybi syndrome (RSTS) is a rare malformation disorder caused by mutations in the closely related CREBBP and EP300 genes, accounting respectively for up to 60 and 3% of cases.

Using FISH and microsatellite analyses as a first step in the CREBBP mutation screening of 63 Italian RSTS patients (pts), 6 deletions were identified, 3 of which were in a mosaic condition that has not been previously reported in RSTS.

Abstract:

To obtain creep-rupture data at low level within a reasonably short time-scale, two accelerated techniques have been investigated. Stepped Isothermal Method (SIM) testing involves loading a single specimen, under constant load, with the temperature increased in a series of steps to accelerate the creep. Careful choice of the temperature step and step duration allow the test to be completed in about 24 hours. At each temperature step a creep curve is obtained; these are then adjusted to compensate for the different temperature levels and a creep master curve at a reference temperature is produc

In the combustion zone of industrial- and aero- gas turbines, thermomechanical fatigue (TMF) is the dominant damage mechanism. Thermomechanical fatigue is a coupling of independent creep, fatigue, and oxidation damage mechanisms that interact and accelerate microstructural degradation. A mixture of intergranular cracking due to creep, transgranular cracking due to fatigue, and surface embrittlement due to oxidation is often observed in gas turbine components removed from service. The current maintenance scheme for gas turbines is to remove components from service when any criteria (elongation,

<p>As more and more constructions are concentrated in densely populated urban areas, there is an increasing need to construct buildings and geotechnical structures on soft clay materials, which usually produce significant creep deformation.

Even today, prediction of the time dependent deformation is generally very problematic.

The role of bonding in the tensile creep behavior of paper was analyzed. This was accomplished by producing handsheets at a range of different bonding levels through manipulation of relative bonded area and specific bond strength. This was done by varying the level of wet pressing (to change relative bonded area) and using debonding and bonding agents (to change specific bond strength). Once manufactured, sheets underwent an extensive battery of physical testing and creep testing. Creep testing was conducted under constant humidity and cyclic humidity (accelerated creep) conditions.

Consequently, this thesis addresses improving the understanding of the creep behaviour for this type of geometry.

The most common destructive evaluation method used today is uniaxial creep testing.

It also demands large sample material outtake which often involve weld repair.

<p>In-service inspections of high temperature pressureequipment show that weldments are prone to creep and fatiguedamage. It is not uncommon that severely damaged weldments arefound even before the design life of the component has beenreached. In order to improve this situation action has beentaken during the last decades, both from industry, universitiesand research institutes, aiming at an enhanced understanding ofthe weldment response.</p><p>The work presented in this thesis focuses on numericalsimulation of weldment creep response. For a more profoundunderstanding of the evolution of creep

Abstract:

Materials used in thermal power plants have to resist creep deformation for time periods up to 30 years. Material evaluation is typically based on creep testing with a maximum duration of a few years. This information is used as input when empirically deriving models for creep. These kinds of models are of limited use when considering service conditions or compositions different from those in the experiments. In order to provide a more general model for creep, the mechanisms that give creep strength have to be identified and fundamentally described. By combining tools for thermodynamic modelli

Abstract:

Snowcovers on slopes densify and deform continuously throughout the winter. These slow, mainly viscous deformations are known as snow creep and this thesis presents an attempt to model them by idealizing snow as a non-Newtonian fluid, where the bulk and shear viscosities depend upon both stress and density. A three-dimensional constitutive law is developed, based largely on analogy with the flow behavior of ice and soil materials. The model, primarily intended for engineering applications (design of structures erected in a deep snowpack), is tested for creep pressures on long rigid obstacles.
