OBJECTIVES The testicular, deferential, and cremasteric arteries and their branches surround the vas deferens (VD), leaving them susceptible to injury during vasectomy. Literature describing the caliber of arteries seen in vasectomy specimens is lacking, making it difficult to categorize the significance of an observed artery. We aimed to establish reference values for arterial size typically e...

Purpose: In this paper the experimental equipment and design of the system for deformation and forming force measuring by single point incremental sheet metal forming are described. Beside this the analysis results of the impact of the wall angle, tool rotation, vertical step size, tool diameter and lubrication on the magnitude of forming force and plastic logarithmic strain are presented. Desi...

BACKGROUND An aortic aneurysm is a local dilation of the aorta, which tends to expand and often results in a fatal rupture. Although larger aneurysms have a greater risk of rupture, some small aneurysms also rupture. Since the mechanism of aortic rupture is not well understood, clarification of the microstructure influencing the failure to rupture is important. Since aortic tissues are stretche...

Abstract Amphistegina are common larger benthic foraminifer in coral reefs, with a nearly circumtropical distribution, and major contributors to the CaCO 3 budget of shallow marine environments. The family Amphisteginidae is dominant Cenozoic carbonates. However, its potential as proxy for paleoclimate reconstruction has not been completely explored. intratest variability trace elements lessoni...

Actual neuroradiological diagnostics of the brain tumors, including astrocytomas, is of great influence on successful planning and realization of the tumor resection, considering the fact that it is oftentimes preoperative. CT diagnostics is the most frequently used method of the brain tumor visualization in Serbia, due to height reliability, short time of the exposition, lower costs, and wide ...
