introduction: vertical root fracture (vrf) is a complication which is chiefly diagnosed radiographically. recently, film-based radiography has been substituted with digital radiography. at the moment, there is a wide range of monitors available in the market for viewing digital images. the present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventi...

PURPOSE To evaluate the changes in thickness of individual inner and outer macular and peripapillary retinal layers in diabetes. METHODS 124 subjects (124 eyes) were enrolled: 74 diabetics and 50 controls. Macular edema, proliferative diabetic retinopathy (DR), any intraocular treatment and refractive error >6 diopters were the main exclusion criteria. Full ophthalmic examination, stereoscopi...

We used ultrasonic imaging to monitor short-term changes in the pectoral muscle size of captive red knots Calidris canutus. Pectoral muscle thickness changed rapidly and consistently in parallel with body mass changes caused by flight, fasting and fuelling. Four knots flew repeatedly for 10 h periods in a wind tunnel. Over this period, pectoral muscle thickness decreased in parallel with the de...

Heat exchangers in operation often experience scaling, which can lead to a decrease heat exchange efficiency and even safety accidents when fouling accumulates certain thickness. To address this issue, manual intervention is currently employed monitor thickness advance. In study, we propose two-layer LSTM neural network model with an attention mechanism effectively learn data under different wo...

background: in high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. here a passive neutron area monitor with cr39 track detector was designed and the response was calculated. materials and methods: the response of a passive neutron area monitor with c...

background: workstation design has shift from using single monitor screen to dual monitor screens, which may impose some impacts towards the muscles activity. this study aimed to determine the effect of using dual monitor screen computer to the neck-shoulder muscle activity among computer user. method: this experimental study was conducted in 2015 among 28 healthy students in university malaysi...

BACKGROUND AND PURPOSE To determine the effect of a lipid-lowering agent and/or a low-dose antithrombotic agent on the progression of early-stage carotid atherosclerosis, noninvasive B-mode ultrasound was used to measure intimal-medial thickness in asymptomatic individuals with moderately elevated lipids as part of the ongoing multicenter Asymptomatic Carotid Artery Plaque Study. METHODS Unif...

This paper reports on the effects of an interactive software tool on the learning of Chinese tones by English-L1 learners of Chinese. The software enables students to listen to model utterances by native speakers of Chinese and to record their own renditions of those utterances. Simultaneously the F0 contours of both the model utterances and the student utterances are displayed on the computer ...

Some interests might feel threatened by the results of his research, but professor Johansson has been outspoken and committed to this scientific field. He started in the 1980's and he has since been continuously very productive and an advocate for the electrosensitive persons in Sweden as well as around the world. This interview will go into what professor Johansson has discovered in the skin o...

Running Head: The effect of visual sources on the perception of compliance using a toolABSTRACT This paper describes a psychophysical experiment which investigates the effect of the source of vision on the perception of compliance with a specific focus on palpation; a basic surgical task. Twelve participants were asked to complete four forced-choice compliance discrimination tasks representing ...
