/ This paper reports an assessment of various methods for sampling particulate surface contami^ nation for use in the field. The results from the study will be used to develop guidance for monitoring particulate surface contamination in the workplace. Three types of adhesive tape, two manual and two 'semi-automatic' wipe methods, and one Smair method were assessed. A field assessment of selecte...

INTRODUCTION The aim of this study was to compare the efficiency of a sonic device (Vibringe), syringe irrigation, and passive ultrasonic irrigation in the removal of debris from simulated root canal irregularities. METHODS Root canals with 2 standardized grooves in the apical and coronal parts were filled with dentin debris. Three different irrigation procedures were performed with NaOCl (1%...

Efficiently Scheduling Tape-resident Jobs Jing Shi, Chunxiao Xing, Lizhu Zhou Department of Computer Science and Technology Tsinghua University Beijing 100084, P.R.China [email protected], {xingcx, dcszlz}@tsinghua.edu.cn Tel: +86-10-62789150 Abstract Many large-scale data-intensive applications need to use tape library to manage large data sets, thus it is critical to study the onl...

Intra-urethral vaginal tape is a rare complication of tension-free vaginal tape (TVT) procedure. A 41year-old woman with intra-urethral vaginal tape after TVT procedure is presented. The presenting symptoms were urge incontinence and dysparonia. The patient has received anticholinergic drugs and vaginal estrogen, but the symptoms had not been resolved with both this regimen. The diagnosis was m...

This study reports the first experimental exploration of possible contagious yawning in monkeys. Twenty-two stumptail macaques (Macaca arctoides) were presented with video clips of either yawns or control mouth movements by conspecifics. At a group level, monkeys yawned significantly more often during and just after the yawn tape than the control tape. Supplementary analysis revealed that the y...

The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...

The mechanics of the "tape" over a flat-head is investigated. It has been recently shown that a thin, flexible tape, traveling over a flat recording head under tension contacts the head over the central area of the head. This phenomenon is due to the selfacting, subambient foil bearing effect. In this paper, as a first order of approximation, a simplified system is analyzed; where a uniform sub...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

OBJECTIVE To determine the efficacy of various eye protection measures during carbon dioxide laser laryngoscopy. DESIGN A standard medical mannequin was equipped with indicator paper over the eyes and subjected to multiple passes of direct carbon dioxide laser beam contact at 400-mm focal length with powers ranging from 2.5 to 4.0 W during simulated laser microlaryngoscopy. Several different ...
