abstract different definitions have been proposed for soil quality. various soil properties have been suggetsted as soil quality indices by researchers. this research was conducted to study the relationship between slope of retention curve at its inflection point (s index) and other soil physical quality indices, because the reserches between s index and soil physical properties are little. thi...

BACKGROUND The number of core biopsies done for breast abnormalities is increasing. The risk of skin seeding resulting from core biopsy is unknown. METHODS Consecutive patients diagnosed with breast cancer were studied. The skin and subcutaneous fat surrounding the site of core needle penetration were excised and studied by routine histologic staining. Findings were correlated with other clin...

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...

Microneedles are being fast recognized as a useful alternative to injections in delivering drugs, vaccines, and cosmetics transdermally. Owing to skin's inherent elastic properties, microneedles require an optimal geometry for skin penetration. In vitro studies, using rat skin to characterize microneedle penetration in vivo, require substrates with suitable mechanical properties to mimic human ...

We report the case of an elderly woman with polycythemia vera submitted to bone marrow biopsy who developed retroperitoneal hemorrhage as a result of direct penetration of the needle through the iliac crest, with damage to the iliolumbar artery, the first branch of the hypogastric artery.
