introduction: pain is the most common complaint of patients referring to emergency department (ed). considering the importance of pain management in ed, this study aimed to investigate the efficacy and feasibility of ultrasound-guided nerve blocks in this setting. methods: 46 patients who came to the ed with injured extremities were enrolled in the study and received either femoral, axillary or...

In this paper we present results of experiments carried out with a route learning system for a mobile robot, conducted in a `real world' environment covering distances of several hundred metres. The system uses no odometry and is based on a self-organising mapbuilding process using perceptual landmarks. A performance metric is deened and used to measure the robot's ability to traverse the route.

What is the large-scale spatial representation that insect foragers such as bees and ants form of their wider nest environs? This is the principal question which the following contributions aim to answer.

Recent research on congestion control in high speed ATM networks has sought to extract statistical multiplexing eeciencies while guaranteeing quality of service. To facilitate network control, traac regulators are positioned at network edges, with Leaky Bucket regulation ubiquitous. We consider the composite of conventional Leaky Bucket regulators, one for each time scale. Over longer time scal...

Recruitment to UK Biobank has begun. The planned recruitment to a cohort of 500 000 men and women aged 40–69 over 5 years remains an ambitious target, but one which demonstrates the scale of study that is required to investigate many emerging research questions. The essential feature of a cohort study, following change over time in exposure and health status at the individual level, is a natura...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...
