Overpressure preventing quartz cementation? - A reply

Insights into rates of fracture growth and sealing from a model for quartz cementation in fractured sandstones

A new model accounts for crystal growth patterns and internal textures in quartz cement in sandstone fractures, including massive sealing deposits, thin rinds or veneers that line open fracture surfaces, and bridge structures that span otherwise open fractures. High-resolution cathodoluminescence imaging of bridge structures and massive sealing deposits indicates that they form in association w...

A new procedure to estimate BLEVE overpressure

Several methodologies, based on different thermodynamic assumptions and requiring substance properties and thermodynamic data, have been proposed in the literature for the prediction of the mechanical energy released by a Boiling Liquid Expanding Vapour Explosion (BLEVE) and the associated overpressure. A new method, simple and easy to use, is presented which only requires the vessel filling de...

[Authors's reply to "Preventing atelectasia at robotic surgery"].

e letter by Yetim et al. discussed mechanical ventiion modes and parameters to prevent hypoxemia and prove lung function during robotic surgery, using Recruitnt Maneuvers (RMs), positive pressure ventilation mode, d Positive End-Expiratory Pressure (PEEP).1 We agree that pressure control ventilation is an option d PEEP and RMs may be needed during robotic surgery. wever, some studies have repor...

Logic Solvers for Overpressure Protection

Introduction A growing level of attention has recently been given to the automated control of potentially hazardous processes such as the overpressure or containment of dangerous substances. Several independent protection methods provide measures to reduce the risk from such hazards to personnel, the environment and assets. A significant level of this risk reduction is allocated to safety instr...
