Hydrodynamics of trickle bed reactors (TBRS) packed with industrial catalyst using advanced measurement techniques
"The impacts of the packing characteristics on the hydrodynamics od a trickle bed reactor (TBR) have been investigated using advanced measurements techniques of Gamma-ray densitometry (GRD) and Optical fiber probe and conventional measurement techniques of high-frequency differential pressure …

Local liquid velocity measurement of trickle bed reactor using digitial industrial X-ray radiography
<p>"Trickle Bed Reactors (TBRs) are fixed beds of particles in which both liquid and gas flow concurrently downward. They are widely used to produce not only fuels but also lubrication products. The measurement and the knowledge of local liquid velocities (VLL) in TBRs is less which is essential …

The Relationship Between Pragmatic Language and Behavior Subtypes in Typically Developing Children
… checklist, and Teacher Behavior Rating Scale (TBRS), a behavior checklist, were completed by three 2nd-grade teachers and three 4th-grade teachers about each of their students. Factor analysis was used to determine two composite language measures from the CCC-2 scales. The results of two …

The Relationship between Social Behaviors and Working Memory in School-Age Children with Language Impairment
… by teachers. The Teacher Behavior Rating Scale (TBRS; Hart and Robinson, 1996) was used to compare social behaviors of 19 school-age children with LI to 19 age-matched peers with typically developing language skills. Social behaviors were divided into two categories, withdrawal and sociability. …

Novel applications of fluorine-18 labelled radiotracers in cardiovascular disease
… expressed as target-to-background ratios (TBRs). Visually, aortic valve 18F-fluoride uptake was similar on PET/CT and PET/MR. TBRMAX values were comparable with radial GRE AC (PET/CT 1.55±0.33 vs. PET/MR 1.58±0.34, p=0.66; 95% limits of agreement -27 to +25%) but performed less well with …
