Distal Radiation Access as an Alternative to Conventional Radial Access for Coronary Angiography and Percutaneous Coronary Interventions (According to TENDERA Trial).

The aim of this study was to assess the immediate and medium-term (3 months) results of the safety and efficacy of distal radial access (DRA) in coronary interventions compared with conventional transradial radial access (TRA). TRA is the recommended access for coronary procedures because of increased safety: fewer local complications, large and small bleeding. Recently, DRA has emerged as a promising alternative access to minimize radial artery occlusion (RAO) risk, as well as other complications.

Strength Parameters of Clay Brick Walls with Various Directions of Force.

The study analyzes the anisotropy effect for ceramic masonry based on experimental tests of samples made of 25 × 12 × 6.5 cm solid brick elements with compressive strength = 44.1 MPa and cement mortar with compressive strength = 10.

Testing Crack Resistance of Non-Load-Bearing Ceramic Walls with Door Openings.

Cracking in non-load-bearing internal partition walls is a serious problem that frequently occurs in new buildings within the short term after putting them into service or even before completion of construction. Sometimes, it is so considerable that it cannot be accepted by the occupiers. The article presents tests of cracking in ceramic walls with a door opening connected in a rigid and flexible way along vertical edges.
