Abstract:
Identification of regions containing plastic strain arising from the welding process is performed through the application of thermoelastic stress analysis (TSA) and finite element (FE) modelling. An approach is developed that removes the requirement to have a physical reference specimen for the component studied by developing a 'synthetic reference bitmap' using finite element analysis. The regions containing plastic strain can be identified with TSA by collecting data from a 'reference' plastic strain free specimen from the TSA data and creating a resultant bitmap. Here, a synthetic bitmap is

Abstract:
In modern times, the ability to investigate the aeroelastic behavior of dynamic components on rotorcraft has become essential for the prediction of their useful fatigue life. At the same time, the aeroelastic modeling of a rotorcraft is particularly complex and costly. Inaccuracies in numerical predictions are mostly due to imprecisions in the structural modeling, to the presence of structural degradation or to the limited information on aerodynamic loads. The integration of experimental measurements on dynamic components such as rotor blades has the potential to improve fatigue estimation, au

Abstract:
A quantitative damage assessment methodology for composite materials has been achieved using Thermoelastic Stress Analysis (TSA). The TSA technique provides fullfield data which is collected in a non-contacting and real time manner. The damage assessment methodology proposed requires a means of calibrating and temperature correcting the thermoelastic signal; these are developed and presented in this thesis. The thermoelastic theory for calibrating thermoelastic data from orthotropic bodies has traditionally been based on a stress formulation. There are difficulties in calibrating orthotropic m

Abstract:
Replication stress is present in cancers cells at higher than normal levels due to the increased proliferation caused by oncogene activation. This results in elevated levels of phosphorylated RPA2 (pRPA2) and DNA damage, which can ultimately result in genetic instability. By inhibiting suppressors of replication stress, it may be possible to target this cancer-specific phenotype to selectively kill tumour cells. Attempts were therefore made to develop a high throughput whole genome RNAi screen to detect increased endogenous levels of pRPA2 foci formation following gene knockdown, however, this

Here, we study the regulation of the prion protein gene (PRNP) in this context, as the regulation of the PRNP gene is not well understood.

The leaf rust resistance gene Rph15 is of outstanding interest for resistance breeding because it confers resistance to over 350 Puccinia hordei isolates collected from around the world (Weerasena et al. 2004).

L'approche systématique et la technique des micropuces à ADN, nous a permis de montrer que parmi 8000 gènes analysés, 239 présentent une expression différente entre le pancréas sain et le pancréas au cours de la pancréatite : 107 gènes étaient sur-exprimés et 132 gènes étaient sous-exprimés. Parmi ces gènes, 96 correspondaient à des gènes non répertoriés auparavant. Dans le but d'identifier de nouveaux mécanismes de défense cellulaire, nous avons caractérisé deux nouveaux gènes. Le premier gène code une protéine de 49 kDa, appelé PIP 49 (Pancreatitis Induced Protein). Il s'agit d'une protéine

Abstract:
The DNA replication machinery encounters a number of obstacles while duplicating the genome, which put the replicative apparatus under stress. Cells have developed a number of mechanisms to overcome replication stress sources. However, in the presence of chronic stress, or after loss of key factors that help to deal with this stress, a range of deleterious events can occur. One of the main pathways implicated in DNA damage sensing and response is DNA damage checkpoint. When DNA replication fork progression is blocked, checkpoint activation ensures structural stability of the replisome componen
