Patients taking oral contraceptive steroids (OCS) are known to suffer failure while anticonvulsants such as phenobarbitone, phenytoin and carbamazepine. We have studied the single dose kinetics of ethinyloestradiol (EE2); 50 micrograms, levonorgestrel (Ng); 250 micrograms in groups women before 8‐12 weeks after starting therapy with (n = 6) carbamazepine 4). The area under plasma concentration‐time curve (AUC) was measured over a 24 h period for each steroid significant reductions were seen...
The work reported in this article addresses the issue of reliability assessment from a systemic perspective. general idea paper is based on observation that failures occur at level elementary components but are induced by stresses emanating form use system and environment which they placed. Within scope, so-called U-Cycle approach developed. It allows, matrix framework, to match levels decomposition functional viewpoint resulting dysfunctional modelling thus involves taking into account...
Background There is limited evidence on the effectiveness of biological therapy in stricturing complications patients with Crohn’s disease. Aim The study aims to determine anti‐tumor necrosis factor (TNF) agents disease complicated symptomatic strictures. Methods In this multicentric and retrospective study, we included adult receiving their first anti‐TNF therapy, no previous history biological, endoscopic or surgical therapy. agent was defined as a composite outcome combining steroid‐free...
In this work, a thermal fatigue study on IGBT modules for aeronautical application is carried out, based accelerated tests and the thermo-mechanical process simulation. The 3D simulation gives us impact of delamination degree module behavior fixes failure criterion. Element Finite metallurgical observations permit providing predictive indication factors to predict crack apparition its propagation inside solder basis creep energy dissipated.
The article first introduces the problem in question and discusses interest implementing a concurrent engineering approach. It focuses on relevant rapid prototyping techniques likely to be used order make design production processes more reliable. Next, describes generic terms advantages of using QFD method as decision making tool. practical case study chosen is related selection resource. After identifying functions fulfilled by resource, technology deployment matrix built principles...
This contribution illustrates the advantages of measures and indicators based on notions Shannon entropy which is widely implemented in thermodynamics, information theory, econometrics, biology. The presented case study applies these to a fleet industrial assets, introducing innovatively concept field availability. There no reason deal effect performance variables assets independently without taking into account disparities terms reliability, operation hours, applied maintenance, operating...
The control of critical electronic components reliability is one the main issues in railway traction applications. Insulated Gate Bipolar Transistors (IGBT) modules are part these components. They subjected to high stresses due severe conditions use train. increase requirements terms and safety imposes be able assess dependability measures. This paper introduces a methodological framework for predicting IGBT based on an innovative structured Bayesian approach.
The weak point for the standard power IGBT modules in terms of reliability is thermal fatigue solder joints due to stress induced by constitutive materials with different coefficients expansion (CTE). So far, many researches are aimed at defining accurate finite element simulation equations behaviour and failure relation connecting inelastic strain number cycles before failure. Even if these relations can be clearly identified, we see that validation model difficult scatter input data. In...
The detrimental effects of metallic on certain key electrical parameters silicon devices mandates the use state‐of‐the‐art characterization and metrology tools as well appropriate control plans. Historically, this has been commonly achieved in‐line monitor wafers through a combination Total Reflectance X‐Ray Fluorescence (TXRF) post anneal Surface Photo Voltage (SPV). On other hand, VPD (Vapor Phase Decomposition) combined with ICP‐MS (Inductively Coupled Mass Spectrometry) or TXRF is known...

This works deals with the seismic vulnerability of buildings in Pyrenees mountains region where almost a thousand earthquakes are recorded each year border area. The challenge is twofold: first to detect damage due events and then localize it inside studied buildings. Operational Modal Analysis (OMA) coupled numerical modelling by Finite Element (FE) constitutes an interesting approach address these issues. Here we intend apply such methodology on strategic building located...
