<p>Pigmented villonodular synovitis (PVNS) is a rare condition, commonly affecting the knee joint and hip joint. It seldomly seen in pediatric age group. Aetiology unknown. Magnetic resonance imaging (MRI) modality of choice. Managed by surgical resection synovium performed with an open, arthroscopic or combined approach.

The aim of this study is to describe a new method for the three-dimensional reconstruction of coronary arteries and its quantitative validation. Our approach is based on the fusion of the data provided by intravascular ultrasound images (IVUS) and biplane angiographies. A specific segmentation algorithm is used for the detection of the regions of interest in intravascular ultrasound images. A n...

Road surface-runoffs have been analyzed using various approaches, but inaccurate analysis methods lead to overestimation of the drainage capacity, causing unexpected flood damage in low-lying urban areas. Previous studies highlighted importance considering parameters for accurate road surface-runoff analysis. This study involves an enhanced approach simplified and modified basin geometries, sur...

Greenhouses are employed worldwide to protect crops from meteorological conditions as well control some plant production variables. As multi-tunnel structures amongst the most used, in this article, we focus on cost optimization of both steel structure and concrete foundation greenhouse typology. Firstly, three structural alternatives composed tunnels differentiated portal frames were dimension...
