background: topical anesthesia has been widely advocated as an important component of atraumatic administration of intraoral local anesthesia. the aim of this study was to use direct observation of children’s behavioral pain reactions during local anesthetic injection using cotton-roll vibration method compared with routine topical anesthesia. materials and methods: forty-eight children partici...

A standard test field containing numerous strong sources has been observed twice with the ASKAP BETA system, with the third axis of motion – the roll axis – disabled for the second run. These two data sets are subjected to identical calibration and imaging pipelines in order to gauge the e↵ects of the roll axis when observing with a Phased Array Feed. Present beam forming techniques only allow ...

This paper presents an effective methodology for the simplified representation of the kinematics and the horizontal flight control of Unmanned Aerial Vehicles (UAVs). A real UAV has been used as a model in this project. The flight behavior of the UAV has been modeled in terms of simple analytic relationships, which proved very helpful in representing UAV’s actual horizontal motion. A fuzzy cont...

Interpretation of opiate drug test results can be challenging due to casual dietary consumption of poppy seeds, which may contain variable opiate content. Opiate concentrations in paired oral fluid (OF), collected with the Oral-Eze(®) Oral Fluid Collection System, and urine were analyzed after ingestion of poppy seeds from the same source, consumed raw or contained in a roll. In Part 1, 12 indi...

BACKGROUND The detection of sub-clinical breast lesions has increased with screening mammography. Biopsy techniques can offer precision and agility in its execution, as well as patient comfort. This trial compares radioguided occult lesion localization (ROLL) and wire-guided localization (WL) of breast lesions. We investigate if a procedure at the ambulatorial level (ROLL) could lead to a bette...

Autonomous walking bipedal machines, possibly useful for rehabilitation and entertainment purposes, need a high energy efficiency, offered by the concept of ‘Passive Dynamic Walking’ (exploitation of the natural dynamics of the robot). 2D passive dynamic bipeds have been shown to be inherently stable, but in the third dimension two problematic degrees of freedom are introduced: yaw and roll. We...

[Purpose] The aim of this study was to compare muscle activity of the posterior oblique sling during prone hip extension (PHE) on the floor and on a round foam roll. [Subjects] Twenty-two (11 male, 11 female) healthy volunteers were recruited for this study. [Methods] The participants performed PHE on the floor and on a round foam roll. Surface electromyography (EMG) was recorded from the contr...

background, aims, methods, results) max 200 words: Tilting trains reduce the perceived lateral acceleration for the passengers by tilting the car-body to improve the ride comfort. However, some susceptible passengers may experience nausea. To study the influence from either lateral accelerations and/or simultaneous roll motions, a simulator study was undertaken. About 40 subjects were taking pa...
