Investigation of Recrystallization Kinetics in 1050 Al Alloy by Experimental Evidence and Modeling Approach.

The recrystallization (RX) kinetics of commercially pure Al alloy is studied under the scope of annealing temperature, time, and degree of deformation. To examine the distribution of recrystallization, Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory is employed, where the path of microstructural transformation from the deformed state to the fully recovered one is studied as a function of the volume fraction of recrystallized grains (XV) and annealing time. The drop in hardness is recorded for the samples at various stages of annealing with a corresponding decrease in stored energy as the annealing time increases.

[Cryosclerosis. The forgotten endovenous cryoablation of the great saphenous vein. Mid-term results of a prospective comparative trial].

Introduction: Cryosclerosis was introduced by Milleret and Le Pivert in the 1980s.

Method: A prospective non-randomized comparative study has been performed on initial 96 patients. 48 patients were treated by cryosclerosis and the others received conventional stripping.

Which endovenous ablation method does offer a better long-term technical success in the treatment of the incompetent great saphenous vein? Review.

Objective: The aim of this review article was to evaluate the long-term technical success rates of the known endovenous ablation procedures in the treatment of the incompetence of the great saphenous vein.

Methods: A literature search was conducted in the PubMed-database until the 5 January 2016. All publications with four to five years follow-up were eligible.

[Pneumoperitoneum after jacuzzi bathing -- an unusual cause for the development of intraperitoneal free air].

Free air within the intraperitoneal cavity most frequently occurs in conjunction with perforation of a hollow viscus and requires urgent surgical intervention. However, approximately 10% of all cases of pneumoperitoneum may not be correlated with disruption of the gastroinestinal tract. In the literature this condition is termed "nonsurgical" (NS) pneumoperitoneum and usually requires conservative management.

[Occult inguinal-hernia in athletes].

Introduction: The occult inguinal hernia in athletes represents a distinct entity as well as a part of a syndrome known as PIPS (public inguinal pain syndrome). It may be relatively difficult to identify the possible source of inguinal pain, since the spectrum is so wide that it can overlap various medical subspecialties.

Patients And Methods: This study includes 14 cases of athletes (11 football players) with suspicion of occult inguinal hernia.
