1. The fate of an immature herbivorous insect depends on its mother’s ability to locate a host that fosters optimal growth. However, immature performance and survival is often decoupled from female host preference. 2. We used defence manipulation and exclusion experiments to investigate how oviposition choices impact survival in the diet-specialised leaf beetle, Acromis sparsa , whose larvae ar...

OBJECTIVE The use of PET in Australia has grown rapidly. We conducted a prospective study of the radiation exposure of technologists working in PET and evaluated the occupational radiation dose after implementation of strategies to lower exposure. METHODS Radiation doses measured by thermoluminescent dosimeters over a 2-y period were reviewed both for technologists working in PET and for tech...

BACKGROUND It is estimated that 60 million computed tomography (CT) scans were performed during 2006, with approximately 11% of those performed on children age 0-15 years. Various types of gonadal shielding have been evaluated for reducing exposure to the gonads. The purpose of this study was to quantify the radiation dose reduction to the gonads and its effect on image quality when a wrap-arou...

Heat shields play a vital role in protecting space vehicles during the atmosphere reentry. Therefore, they are essential for space vehicles, and better designed heat shields will vastly improve the ability both of robots and humans to explore extraterrestrial destinations. The main goal of the current paper is to investigate the feasibility of designing, building and deploying a tensegrity-base...

T he clinician is often confronted with the problem of treating an extensive periapical lesion which may be cystic as a result of pulpal pathosis. Surgical management by curettement and/or apical resection has usually been the accepted procedure for such lesions. However, in cases in which extensive periapical lesions are visualized on the roentgenograms, a surgical approach can create complica...

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease. FMD once considered rare, is increasingly a condition recognised as an incidental finding. It is an important cause of stroke especially in younger, female patients and therefore a high index of suspicion is required. FMD has distinct pathological findings along with some pathognomonic angiographic findin...
