shear wave velocity is a basic engineering tool required to define dynamic properties of soils. in many instances it may be preferable to determine vs indirectly by common in-situ tests, such as the standard penetration test. many empirical correlations based on the standard penetration test are broadly classified as regression techniques. however, no rigorous procedure has been published for c...

A 10-month-old male baby presented with irritability and inconsolable cry for last two weeks which increased on touching the chest. There was no history of fever, respiratory symptoms, or any accident. On examination, an indurated tender nodule over right lower chest was present. Chest x-rays showed a metallic foreign body at right lower chest extending from skin to pleural cavity (Fig.1A,1B). ...

Over 160 cases of injury to the heart by pins and needles have been reported (Hermoni et al., 1986). These objects reached the heart by a number of routes including embolization and penetration from adjacent organs after ingestion. However the most common mode of injury was by direct transthoracic penetration and the majority of these were accidental in nature. We present the history of a 22-ye...

Simultaneous recording of the electrocardiogram and of the pressure transmitted through the drainage needle in patients with haemopericardium provided confirmation that the needle tip was in the pericardial cavity. Proper position was indicated by a positive pressure wave beginning before the QRS complex, reaching its maximum value in the first part of the ST segment and ending with the T wave....

This study aims to investigate the dynamics characteristics of liquid jet injected from a needle-free injection device by analyzing the the flow visualization from the high-speed video camera and the CFD calculation. This is to investigate the jet flow phenomena (e.g. penetration, dispersion, velocity) in the quiescent air and in the tissue simulant (20% polyacrylamide gel) as the further infor...
