The paper describes a methodology for the field modelling of non-charring flame spread over representative solid surfaces. Coupled descriptions of the controlling mechanisms of buoyancydriven flow, combustion, soot production, radiation heat transfer and solid pyrolysis are incorporated into a fire-specific CFD code. The approach is evaluated at sub-model level and in a room corner fire configu...

Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...

PURPOSE After liver transplantation with a small-for-size liver graft or after extensive hepatectomy for liver malignancies or other non malignant conditions with an insufficient liver volume, the survival of patients depends on liver regeneration. This study was carried out in order to create a new porcine model for the study of small-for-size syndrome (SFSS) after extensive hepatectomy. MET...

Laser-ablation experiments on solid (T = 300 K) and liquid (T = 600 K) indium are reported. The ablation was performed under high vacuum conditions with UV laser pulses at 248 nm and pulse durations of 15 ns and 0.5 ps. The ablated neutral indium atoms were resonantly ionized with a second laser pulse 28 mm above the sample surface and detected in a time-of-flight mass spectrometer. The ablatio...

This paper presents an analytical review of data on the interaction of volatile corrosion inhibitors with the atmosphere, vaporization processes, methods of experimental and computational estimation of the vapor pressure of organic compounds, and effects of vaporization conditions and compound structure on vapor pressure.

UV laser ablation of polymers was discovered 20 years ago.1,2 This effect has many fascinating applications in lithography, micromechanics, and medicine. For the last 20 years, more than 103 papers describing this phenomenon were published (see, e.g., comprehensive reviews, refs 3-7). Despite the high research activity, the nature of UV laser ablation of polymers is still far from being fully u...

Coherent Sine Burst Electroporation (CSE) uses phased sine waves for pulsed field ablation (PFA). This approach offers high versatility in titration of lesion depth, width and shaping comparison to traditional square wave ablation. Investigate the ablative capacity safety CSE generated lesions various depths shapes using a multi-configurable (linear, circular, focal) catheter. Open-chest charac...

BACKGROUND The aim of this study was to investigate the feasibility of the application of high-intensity focused ultrasound (HIFU) hat-type ablation mode in in vitro and in vivo models, and to compare the ablation effects of different parameter combinations. MATERIAL AND METHODS HIFU hat-type ablation was performed in isolated bovine liver tissue and in the liver tissue in living rabbits, and t...
