among the power drills ( electrical/ pneumatic/battery ) used in orthopedic surgery, battery drill has got several advantages. surgeons in low resource settings could not routinely use orthopedic battery drills (obd) due to the prohibitive cost of good drills or poor quality of other drills. “hardware” or engineering battery drill (hbd) is a viable alternative to obd. hbd is easy to procure, ru...

The complexity of modern products and design tools has complicated the exchange of design information. It is widely recognized that the capture, storage, and retrieval of design information is one of the major challenges for the next generation of computer aided design tools. This paper presents a model for the flow of design information that supports a semantics-based approach for developing i...

OBJECTIVES To study the use of cellular and cordless telephones and the risk for malignant brain tumours. METHODS Two case-control studies on malignant brain tumours diagnosed during 1997-2003 included answers from 905 (90%) cases and 2,162 (89%) controls aged 20-80 years. We present pooled analysis of the results in the two studies. RESULTS Cumulative lifetime use for >2,000 h yielded for ...
PURPOSE Dental professionals suffer from a high prevalence of work-related musculoskeletal disorders (MSD). Dental hygienists in particular have a high prevalence of pain in the forearms and hands. The objective of this study was to compare 1 cordless handpiece to 2 corded handpieces during simulated tooth polishing in terms of the muscle loads (recorded as electromyography (EMG) activity), dur...
BACKGROUND A previous study found an association between maternal cell phone use during pregnancy and maternal-reported child behaviour problems at age 7. Together with cell phones, cordless phones represent the main exposure source of radiofrequency-electromagnetic fields to the head. Therefore, we assessed the association between maternal cell phone and cordless phone use during pregnancy and...
Modern research in high energy physics depends on the ability to analyse massive volumes of data in short time. In this article, we report on DeLorean, which is a new system architecture for high-volume data processing in the domain of particle physics. DeLorean combines the simplicity and performance of relational database technology with the massive scalability of modern cloud execution platf...
