RATIONALE The role of hypertension in cerebral small vessel disease is poorly understood. At the base of the brain (the 'vascular centrencephalon'), short straight arteries transmit blood pressure directly to small resistance vessels; the cerebral convexity is supplied by long arteries with many branches, resulting in a drop in blood pressure. Hypertensive small vessel disease (lipohyalinosis) ...

On the Influence of Mechanical Behavior of the Middle Ear Ligaments: a Finite Element Analysis Fernanda Gentil1, Renato Natal Jorge2, António Joaquim Mendes Ferreira3 Marco Parente4, Pedro Martins5, Eurico de Almeida6 Summary The interest in finite element method (FEM) concerning biomechanics has been increasing, in particular, to analyze the mechanical behavior of the human ear. In this work, ...

ASME Boiler and Pressure Vessel Code Section VIII Division 1 [1] is one of the most commonly used pressure vessel codes in the world. The Division 1 rules were originally written before the age of computers; they were intended to be solved by simple hand calculations. This simplification led to rules with a high safety margin and a conservative technical basis. In 2007, ASME published a complet...

Abstract MXene aerogels have shown great potential for many important functional applications, in particular electromagnetic interference (EMI) shielding. However, it has been a grand challenge to create mechanically hyperelastic, air‐stable, and durable enabling effective EMI protection at low concentrations due the difficulties achieving tailorable porous structures, excellent mechanical elas...

Liquefied Petroleum Gases [LPG] are flammable mixtures of gases such as propane and butane mainly which is transported stored in liquid phase storage vessels under amply pressure. These industrial processes high fire explosion hazard. When a vessel carrying LPG damaged, an abrupt drop pressure may release colossal quantities evaporating gas energy that has destructive effect on the itself its s...
