For the purpose of this study, four natural rock samples-namely, diorite, granodiorite, tonalite, and granite-are being investigated about their radiation attenuation. The elemental composition of the rocks was obtained through Energy dispersive X-ray spectroscopy (EDX) which examines the microstructural and localized area elemental analyses of the four rock samples. A Monte Carlo simulation (MCNP) was used to determine and evaluate the investigated samples.

Article Synopsis
  • The study investigates the radioactivity and radiological risk of various granites and marbles from Egypt, using a Germanium detector to measure activity levels.
  • It found that granite samples had significantly higher levels of radioactivity compared to marble samples, with average activity concentrations for granite exceeding global soil averages.
  • The presence of potassium feldspar in granites is attributed to the increased radioactivity, while marbles are considered safer due to their lower potassium and uranium/thorium content.

Background and objective Missing information or mistakes in patients' medical records, including those related to intraoperative and postoperative information, in an operative note can have profound clinical, ethical, and medicolegal implications. Operative notes should be informative, clear, and inclusive of the necessary data and should be collated immediately following surgery. In this study, we aimed to determine the ways to improve the quality of operative notes in the field of vascular surgery.

Objectives: Persistent sciatic artery (PSA) is a rare congenital anomaly, whereby the embryonic sciatic artery remains patent with associated degrees of femoral axis hypoplasia. Aneurysmal degeneration and distal ischaemia from thromboembolic complications are common. Revascularisation strategies include embolectomy, bypass or interposition grafting and catheter-directed thrombolysis.

Background: Endovascular intervention for chronic symptomatic type B aortic dissection (CS-TBAD) induces aortic wall stress with negative hemodynamic cardiovascular consequences. CS-TBAD risks increased morbidity and mortality due to septum maturation with significant impact on false lumen modulation, and partial lumen thrombosis conveying the worst outcome. The aim of the TIGER technique is total aortic remodeling with true lumen expansion, false lumen regression and complete thrombosis, and stabilization of overall aortic diameter.
