Natural gas hydrates (NGHs) are efficient and promising energy resources because of their high density. In addition, NGH occurs in sediments under certain pressure temperature conditions has the potential to meet increasing global demand. However, exploitation requires a precise characterization understanding hydrate formation, accumulation, dissociation mechanisms. this context, microstructura...

BACKGROUND AND PURPOSE (18)F-FAZA is a nitroimidazole PET tracer that can provide images of tumor hypoxia. However, it cannot provide absolute pO(2) values. To qualify (18)F-FAZA PET, we compared PET images to pO(2) measured by OxyLite, EPR oximetry and (19)F-MRI. MATERIALS AND METHODS Male WAG/Rij rats grafted with rhabdomyosarcoma were used. Tumor oxygenation was modified by gas breathing (...

We present an integrated approach to imaging the progress of air displacement by spontaneous imbibition of oil into sandstone. We combine Computerized Tomography (CT) scanning and neural network image processing. The main aspects of our approach are I) visualization of the distribution of oil and air saturation by CT, 11) interpretation of CT scans using neural networks, and III) reconstruction...

ct image quality has been affected by many factors such as kvp, ma, exposure time, alogorithm and section thickness. gantry tilt has the main role in visualization of the temporal bone anatomic structures. in this study, we tried to optimize these factors to determine the best gantry tilt. this study was performed on the human skull phantom and then extended to 15 patients. the phantom was made...

Abstract Background Pulmonary tumor thrombotic microangiopathy (PTTM) is a condition that involves the development of pulmonary hypertension due to presence microscopic emboli peripheral arteries. Here, we report case rapidly exacerbating PTTM associated with gastric cancer was identified postmortem through pathological autopsy. Case presentation A 52-year-old Asian woman who experienced anteri...
