The effect of thoracolumbar high velocity low amplitutde manipulation on gross trunk rotational range of motion: is the position of the technique important?
… on the gross trunk rotational range of motion (GTR) of the spine in an asymptomatic population. Ninety subjects (57 female, 33 male) aged 18 to 40 years were randomly allocated into three intervention groups; receiving either a HVLA manipulation in the side-lying position, a HVLA manipulation in …

Investigation into a GPS time pulse radiator for testing time-stamp accuracy of a radio telescope
… to UTC. A portable GNSS time-pulse radiator (GTR) device for testing the time-stamp accuracy was developed. The GTR was calibrated at the National Metrology Institute of South Africa and laboratory characterisation tests measured its RF timing pulse to be 1.32 ± 0.100 µs ahead of the UTC …

Ependymal tumours in childhood: outcomes and prognostic factors
… tumours (70,6%). Gross total resection (GTR) was achieved in 22 patients (43,1%). Thirtyeight patients received adjuvant radiotherapy (76,5%) and 10 (19,6%) received adjuvant chemotherapy. RESULTS: The 5-year overall survival (OS) was 63,3 % (median follow up of 46 months). The 5 year …

Investigation of the application of polylactic acid-calcium phosphate composite materials as novel periodontal barrier membranes
… of the periodontium. Guided tissue regeneration (GTR) is one technique that is used clinically to promote tissue regeneration. The technique employs a membrane to create space in the appropriate surgical site to produce periodontal regeneration. However there may be considerable potential to …

The evolution of the tuba quartet and its repertoire
… the Tuba Repertoire: The New Tuba Source Book (GTR) to identify important trends in the development of tuba quartet repertoire. This document, which may be the first project of its kind to review such a large body of repertoire for a musical medium, identifies the most prevalent tuba quartet …

Test Development and Material Characterization of Hot Poured Crack Sealant at Low Temperature
… improves. However, if the ground tire rubber (GTR) is added, the improvement of tensile property is reduced, but the flexural strength is increased.

Assessing the impact of greentree reservoir water management on red oak growth and anatomy in the lower Mississippi Alluvial Valley
… waterfowl habitat, greentree reservoirs (GTRs) were established, providing artificial flooding during the fall and winter. Red oak species within GTRs provide vital resources, such as mast and habitat for wildlife, and make up an important part of waterfowl conservation. However, many GTRs …

Performance analysis of asphalt mixtures modified with ground tire rubber and recycled materials
… (RMA) product containing ground tire rubber (GTR) and a common elastomeric polymer, tested alongside a mature terminal-blend GTR product commonly used in Chicago and surrounding areas. The study investigates the low-temperature performance of the mixtures and their durability in terms of …

Analysis of the impact on phylogenetic inference of non-reversible nucleotide substitution models
… better fit than the General Time Reversible (GTR) and NREV6 models to 21/31 dsRNA and 20/30 dsDNA datasets. As expected, however, NREV12 provided a significantly better fit to 24/33 ssDNA and 40/47 ssRNA datasets. I tested how non-reversibility impacts the accuracy with which phylogenetic …
