Effects of Austenitization Temperature and Pre-Deformation on CCT Diagrams of 23MnNiCrMo5-3 Steel.

The combined effect of deformation temperature and strain value on the continuous cooling transformation (CCT) diagram of low-alloy steel with 0.23% C, 1.17% Mn, 0.

Correlation among the Power Dissipation Efficiency, Flow Stress Course, and Activation Energy Evolution in Cr-Mo Low-Alloyed Steel.

In the presented research, conventional hot processing maps superimposed over the flow stress maps or activation energy maps are utilized to study a correlation among the efficiency of power dissipation, flow stress, and activation energy evolution in the case of Cr-Mo low-alloyed steel. All maps have been assembled on the basis of two flow curve datasets. The experimental one is the result of series of uniaxial hot compression tests.

[Results of an epidemiologic surgery carried out with men 50-80 years of age to study urinary disorders, quality of life and sexual function].

Objective: The prevalence of urinary symptoms, their impact on quality of life and sexuality and the man's attitude in relation to these problem were studied by a self-administered questionnaire (including I-PSS, 6 questions of DAN-PSS-1, BPHQL9 and IIEF).

Material And Methods: This questionnaire was sent by mail to a national representative sample of 3,500 French men aged 50 to 80 years. Of the 2,372 men who returned an interpretable questionnaire, 21%, 33% and 42% belonged to the severe or moderate category for symptoms, tolerance of symptoms, and alteration of quality of life, respectively.

[Piezoelectric ESWL for ureteral calculi. Impact of topography and lithiasis measurements on therapeutic approaches and performance].

Objective: To evaluate the influence of the site and dimensions of ureteric stones on the modalities and performances of in situ piezoelectric extracorporeal shockwave lithotripsy (ESWL).

Material And Methods: A population of 385 patients with solitary radiopaque ureteric stones was analysed. The long axis of these stones (211 (55%) lumbar, 38 (10%) iliac and 136 (35%) pelvic stones) ranged from 5 to 21 mm (mean = 8.
