It is the purpose of this paper to evaluate the accuracy and safety of the currently prescribed design rules in Eurocode 3: Part 1.2 for the evaluation of the resistance of duplex stainless steel columns and beam-columns. This evaluation is carried out by performing numerical simulations on Class1 and Class 2 stainless steel H-columns. These numerical simulations are performed using the program SAFIR. Eurocode 3 states that stainless steel structural members, subjected to high temperatures, must be designed with the same formulae used for carbon steel members. However, as these two materials have different constitutive laws, it should be expected that, different formulae for the calculation of member stability should be used for fire design. It is considered buckling in the two main cross-section axis, and, in the case of the beam-columns, different bending moment diagrams. Parametric studies of the behaviour of the duplex EN 1.4462 stainless steel grade (austenitic-ferritic in Eurocode 3) columns and beam-columns subjected to fire are presented. [less ▲]

Our objective was to assess how far the progress in ultrasound devices has increased feasibility and accuracy of Duplex ultrasound (DUS) for the diagnosis of renal artery stenosis (RAS), in a population with high prevalence of atherosclerotic renovascular lesions. Ninety-one hypertensive patients with atherosclerotic disease were prospectively evaluated by both DUS and digital subtraction angiography (DSA) of the renal arteries. Only proximal criteria (peak systolic velocity >180 mm/s or renal-to-aortic ratio >3.5) were used for the diagnosis of significant RAS (>60% narrowing). For both techniques, two readers were involved for interobserver variability study. Two hundred one arteries were demonstrated by DSA on 182 available kidneys. The prevalence of RAS among the study group was 37%. Sixteen of the 19 accessory arteries were not seen at DUS; in 8 patients, one renal artery was not seen at DUS (feasibility 91%). On the 177 arteries assessed, in comparison with DSA, DUS yielded 96, 91, and 97% mean values of accuracy, sensitivity, and specificity, respectively. Kappa for interobserver agreement was 0.95 for DUS and 0.92 for DSA. Although still unreliable for the detection of accessory arteries, DUS is in our experience an accurate and reproducible diagnostic test for RAS. [less ▲]

A case of a duplication of the left vertebral artery associated with a premedullary epidermoid cyst at the level of the foramen magnum is described. The close proximity of the two malformative lesions in the present case and the overlap of the periods when such developmental abnormalities can arise suggest that they might be causally linked.

We identified a duplication of the MYB oncogene in 8.4% of individuals with T cell acute lymphoblastic leukemia (T-ALL) and in five T-ALL cell lines. The duplication is associated with a threefold increase in MYB expression, and knockdown of MYB expression initiates T cell differentiation. Our results identify duplication of MYB as an oncogenic event and suggest that MYB could be a therapeutic target in human T-ALL. [less ▲]

Le choix des matériaux utilisés dans la construction repose sur des critères techniques identifiables et quantifiables tels la résistance mécanique, le comportement chimique ou le transfert de chaleur, paramètres qui permettent non seulement de satisfaire les exigences opérationnelles de l'ouvrage, mais aussi d'en garantir la durabilité et la durée de vie utile attendues. Quoi qu'il en soit, ces critères ne sont aujourd’hui plus suffisants: énergie grise, analyse de cycle de vie, incidence sur l’environnement, qualité environnementale des constructions, etc. sont de nouveaux facteurs qui interviennent dans le caractère « durable » des constructions. L’ingénieur se doit désormais d'intégrer ces considérations dans le dimensionnement et la réalisation des ouvrages, ce qui constitue un réel challenge pour l’avenir. [less ▲]
