    Description / Table of Contents: Résumé Dans le but d'éclaircir certains aspects contradictoires de la description du drainage veineux du pancréas, une revue de la littérature et une recherche anatomique ont été effectuées. Cinquante blocs duodénopancréatiques ont été étudiés selon la technique d'injection-corrosion, desquels 45 ont été retenus pour l'étude du pancréas droit et 37 pour celle du pancréas gauche. Le drainage veineux du duodéno-pancréas est assuré suivant deux territoires: un postérosupérieur et un antéro-inférieur, le premier se drainant vers la v. porte et le deuxième dans la v.mésentérique supérieure. La charnière entre les deux est représentée par la v. pancréatico-duodénale inférieure et postérieure (PDIP). Quatre veines assurent le drainage duodéno-pancréatique: pancréatico-duodénale supérieure et antérieure (PDSA), pancréatico-duodénale inférieure et antérieure (PDIA), pancréatico-duodénale supérieure et postérieure (PDSP) et pancréatico-duodénale inférieure et postérieure (PDIP). La veine la plus importante de la face ventrale est la PDSA, celle de la face dorsale est la PDSP. Deux arcades, antérieure et postérieure, ont été retrouvées dans la plupart des cas. Le pancréas gauche se draine dans la v. splénique à travers plusieurs branches collatérales. D'autres veines participent au drainage veineux de l'isthme, du corps et de la queue du pancréas, dont la v. pancréatique inférieure ou transverse.
    Notes: Summary With the aim of clarifying certain contradictory aspects of the description of the venous drainage of the pancreas, a review of the literature and an anatomic study were carried out. Fifty duodeno-pancreatic blocks were studied by the injection-corrosion technique, of which 45 were available for study of the right pancreas and 37 for that of the left pancreas. The venous drainage of the duodeno-pancreas is effected via two territories: a posterosuperior and an anteroinferior, the former draining toward the portal v. and the second into the superior mesenteric v. The borderline between the two is represented by the inferior posterior pancreatico-duodenal (IPPD) v. Four veins ensure duodeno-pancreatic drainage: the superior anterior, inferior anterior, superior posterior and inferior posterior pancreatico-duodenal vv. (SAPD, IAPD, SPPD and IPPD). The major vein of the ventral aspect is the SAPD; that of the dorsal aspect is the SPPD. Two arches, anterior and posterior, were found in the majority of cases. The left pancreas drains into the splenic v. via several collateral branches. Other veins participate in the venous drainage of the isthmus, body and tail of the pancreas, including the inferior or transverse pancreatic v.

    Notes: Abstract Stress-strain curves of slowly cooled and/or quenched Al-4.5 wt.% Mg alloy samples were studied in the temperature range from 473 K to 553 K. Two main temperature regions of relaxation have been found, a low temperature region (below 493 K) and a high temperature region (above 513 K); a transient region lies between these temperatures. The parabolic work hardening coefficient, the fracture time, the yield stress and the fracture stress of annealed and quenched samples have been found to decrease with increasing deformation temperature and to exhibit minimum values at 493 K. The X-ray analysis of the slowly cooled and quenched samples has shown that the lattice parameter a of the aluminium matrix reaches a minimum value at 493 K.

    Notes: Abstract Transient and steady state creep of Al-4.5 wt. % Mg alloy was studied under various constant stresses ranging from 91 MPa to 117 MPa in the temperature range from 473 K to 553 K. The results of creep characteristics have shown two main deformation temperature regions (below 493 K and above 513 K as well as a transient region between these temperatures). Peak values of transient creep parametersB andn were obtained at 493 K. The transient creep parameterB was related to the steady state creep rate εst through the exponentγ which was found to range from 0.85 to 0.5. The stress exponentm′ of the steady state creep has been found to be minimum at the steady state strain peaks, which is characteristic of dislocation climb along the grain boundaries. Microstructural analysis confirmed that the above mentioned mechanism took place in the dissolution region ofβ-phase.
