Microbial desulfurization of ground tire rubber (GTR): Characterization of microbial communities and rheological and mechanical properties of GTR and natural rubber composites (GTR/NR)

Polymer Degradation and Stability, 2019
Abstract This study focused on the characterization of microbial communities during the desulfurization of ground tire rubber (GTR) by two bacterial strains i) Gordonia desulfuricans DSM 44462T, and ii) Rhodococcus sp. AF21875. Automated ribosomal inter-genic spacer analysis (ARISA), and high throughput sequencing of 16S rRNA gene amplicons were ...

Effects of GTR and Treated GTR on Asphalt Binder and High-RAP Mixtures

Journal of Materials in Civil Engineering, 2014
One approach to produce environmentally friendly and cost effective asphalt mixtures is to use more readily available recycled materials like reclaimed asphalt pavement (RAP) and rubber. In this study, ground tire rubber (GTR) and treated ground tire rubber (TGTR) were added to an asphalt binder and to high RAP content mixtures.

Towards the Interoperability between GTRS and EUMEDGRID

2008 IEEE Asia-Pacific Services Computing Conference, 2008
Grid computing enables sharing, selection, and aggregation of a wide variety of geographically distributed computational resources such as supercomputers, clusters, storage systems and data sources. A grid presents them as one unified resource for solving large-scale and data intensive computing applications.

Ground Tire Rubber (GTR) Reclamation: Virgin Rubber / Reclaimed GTR (RE)Vulcanizates

Rubber Chemistry and Technology, 2004
Abstract Thermochemically partially devulcanized ground tire rubber (GTRD) was revulcanized in compositions with different virgin rubbers. Two different devulcanizing groups (mixture of softeners) with and without processing oil have been used for GTR treatment.

GTR adaptive drive and protection

[1992] Proceedings of the IEEE International Symposium on Industrial Electronics, 2003
Obvious advantages are inherent in the adoption giant transistors (GTR) as the power elements to make up pulsewidth modulated (PWM) inverters. The development of improved GTR characteristics has great connection with the base drive circuit. The authors describe the best drive and protection of GTR and put forward the best drive circuit with protective ...

Energy Conservation in GTR

Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2000
Abstract The topics of gravitational field energy and energy-momentum conservation in General Relativity theory have been unjustly neglected by philosophers. If the gravitational field in space free of ordinary matter, as represented by the metric g ab itself, can be said to carry genuine energy and momentum, this is a powerful argument for ...

GTR component of planetary precession

Resonance, 2017
Even as the theory of relativity is more than a hundred years old, it is not within easy reach of undergraduate students. These students have an insatiable urge to learn more about it even if the full machinery of the tools required to study the same is not within their comfortable reach.

Physicochemical, mechanical, and biological properties of commercial membranes for GTR

Journal of Biomedical Materials Research, 2001
AbstractBarrier membranes for guided tissue regeneration (GTR) to treat bone defects have to satisfy criteria of biocompatibility, cell‐occlusiveness, spacemaking, tissue integration, and clinical manageability. In this study, the morphological and mechanical properties of two commercial biodegradable membranes (Resolut® LT and Biofix®) as a function ...

Processing, physico-mechanical and thermal properties of reclaimed GTR and NBR/reclaimed GTR blends as function of various additives

Polymer Degradation and Stability, 2017
In this work, ground tire rubber (GTR) was mechano-chemically reclaimed in the presence of bitumen and various additives. During studies three types of processing and curing additives: (i) peptizer P300; (ii) vulcanization accelerator tetramethylthiuram disulfide (TMTD) and (iii) organic peroxide di(2-tert-butyl-peroxyisopropyl)benzene (BIB1) were ...

The need for GTR therapy.

Postgraduate dentistry, 2001
Guided tissue regeneration (GTR) affords the clinician the ability to successfully manage a variety of severe periodontal problems, without engendering the prosthetic commitment necessary for the use of root resective techniques. However, such therapy is highly diagnostic- and technique-sensitive.
