5-S-cysteinyldopa is a well-known pigment intermediate and analysis of its plasma concentration is interesting for the early diagnosis, as well as for evaluation of treatment and follow-up of malignant melanoma. A determination method of 5-SCD in human plasma was developed using solid phase extraction (SPE) on disposable cartridges and liquid chromatography electrospray mass spectrometry (LC-ESI-MS-MS). Compound's sensitivity to light and oxidation requires the addition of anti-oxidative agents (AO), to work in acidic media at 4 degrees C and to avoid light exposure of samples since blood collection. Different solid phases involving covalent binding to phenylboronic groups or dual retention mechanisms were evaluated and extraction cartridges containing both hydrophobic and strong cation exchange functionalities were finally selected. The LC separation of 5-SCD from endogenous catecholamines was achieved by gradient elution on a C18 stationary phase. 5-SCD was detected by multiple reaction monitoring (MRM) performed on ES(+) generated ions. Finally, the method was prevalidated in the lower ng/ml range. Good results with respect to accuracy, trueness and precision were obtained. [less ▲]

An on going project whose goal is the development and identification of a mathematical model of steel at elevated temperature using a mesoscopic approach is presented. The research aims to study the damage process at elevated temperature using information from the macroscopic and mesoscopic scales. As a final application our results will be used to study the industrial process of continuous casting of low carbon steel. [less ▲]

To improve the image quality of X-ray replicated mirror, A new metrology machine has been built link to a ion beam figuring machine. The first one allows to accurately measure the shape of replicated X-ray mirrors. The machine is dedicated to cylindrical mirrors shape whose dimensions can vary from 50 to 800 mm in height and 600 to 800 mm in diameter. The present contribution will sum up the results achieved with this machine on an actual mirror. The machine calibration results and the data analysis to obtain the mirror final shape will be detailed. The final results are compared with other measurements performed by a traditional 3-D machine. The second one is a dedicated ion figuring machine dedicated for the figuring of the X-ray mirrors. The preliminary tests were undertaken to evaluate the ion figuring process on Nickel replicated surfaces. Those results were used to improve the design of the figuring machine, a detailed description of that machine follows. The reliability of the ion figuring process is shown through an actual problem. Finally, some leading remarks about the improvements of the ion figuring ion machine and the ion figuring process in general are drawn. [less ▲]

The object of the second phase of the study is a technical support/advise to the construction of a portable prototype equipment for on site segregation of tires at the retreading stage. The final equipment aims at identifying the composition type of the rubber of the treads : either high natural rubber content (>60%) or high synthetic rubber content. An additional goal of the study is to elaborate the functional specifications for a handheld compound analyser to be coupled to the Goodyear viscoelasticity tester. [less ▲]
