OBJECTIVE This paper examined neurophysiological correlates of speech in children with language impairment (LI) and typical language development (TLD) across four experiments using different speech stimuli and tasks. METHODS The T-complex event-related potential (ERP) components and other ERP components (e.g., mismatch negativity [MMN]; N400) were examined. A subset of the children participat...

Bypass of Ess1 (Bye1) is a nuclear protein with a domain resembling the central domain in the transcription elongation factor TFIIS. Here we show that Bye1 binds with its TFIIS-like domain (TLD) to RNA polymerase (Pol) II, and report crystal structures of the Bye1 TLD bound to Pol II and three different Pol II-nucleic acid complexes. Like TFIIS, Bye1 binds with its TLD to the Pol II jaw and fun...

INTRODUCTION In India, official and centralized personnel monitoring service using film badge was started in 1952 by Bhabha Atomic Research Centre, Bombay (1). With the indigenous development of a TLD badge system (2) based on CaSO4:Dy Teflon disc dosimeter (3) exhibiting evident superiorities over film badge, replacement of film based individual dosimeter by TLD was initiated in 1975. At prese...

The impact of language impairment on audio-visual integration of speech in noise is examined here by testing the influence of the degradation of the auditory and the visual speech cue. Fourteen children with specific language impairment (SLI) and 14 age-matched children with typical language development (TLD) had to identify /aCa/ syllables presented in auditory only (AO), visual only (VO) and ...

Since the beginning of its use, radiation has already presented harm, justifying the necessity of controlled use. In order to monitor its effects and even avoid them, dosimetry has arisen. For the purpose of ensured all the necessary safety and monitor areas where there is radiation use, a lot of devices able to identify and quantify many types of radiation were developed. However, some these d...

PURPOSE To compare children with typical language development (TLD) and evolutional phonological disorder (EPD) regarding the phonemic discrimination and the linguistic performance of language levels (morphological, syntactic, semantic, and perceptual and productive vocabulary). METHODS The sample comprised 36 children, aged between 5 years and 7 years and 11 months, with TLD and EPD. Childre...

Complex intensity-modulated radiation therapy (IMRT) treatment plans require rigorous quality assurance tests. The aim of this study was to independently verify the delivered dose inside the patient in the region of the treatment site. A flexible naso-gastric tube containing thermoluminescent dosimeters (TLDs) was inserted into the oesophagus via the sinus cavity before the patient’s first trea...

Radiation doses to Patient during CT scanner and the radiological risk are significant. Patient dose survey has been conducted toinvestigate the Iraq patient radiation dosesreceived in CT scanners in order to established reference dose levels. These doses are Entrance Surface Dose (ESD),computed tomography dose index(CTDI)), and dose length product (DLP). Two CT scanner were investigated in thi...

BACKGROUND Purpose of the present work was to investigate thermoluminescent dosimeters (TLDs) response to intraoperative electron radiation therapy (IOERT) beams. In an IOERT treatment, a large single radiation dose is delivered with a high dose-per-pulse electron beam (2-12 cGy/pulse) during surgery. To verify and to record the delivered dose, in vivo dosimetry is a mandatory procedure for qua...

Radiation effects of photon irradiation in Ytterbium-doped silica optical fibers are still much less explored despite their importance in space-based application as radiation dosimetry. This study investigates and compares the thermoluminescence glow curve, response, linearity and sensitivity of Ytterbium-doped SiO2 optical fibers with that of TLD-100. Samples are placed in solid phantom and ir...
