Structural, Thermal and Mechanical Assessment of Green Compounds with Natural Rubber

open access: yesMacromol
The inadequate disposal of tires poses a significant threat to human health and requires effective recycling solutions. The crosslinked structure of rubber, formed through sulfur bridges during vulcanization, presents a major challenge for recycling ...

GTR and Perpetuum Mobile Rehabilitation

open access: yes, 2019
First of all, the author solemnly declares that he recognizes the energy conservation law (understanding, however, that it will not help). Next we shall show that this law does not contradict the possibility of building a perpetual motion machine that uses the force of gravity.

Video-based analysis of the blink reflex in Parkinson’s disease patients

open access: yesBioMedical Engineering OnLine
We developed a video-based tool to quantitatively assess the Glabellar Tap Reflex (GTR) in patients with idiopathic Parkinson’s disease (iPD) as well as healthy age-matched participants.

Preoperative assessment of tumor consistency and gross total resection in pituitary adenoma: Radiomic analysis of T2-weighted MRI and interpretation of contributing radiomic features

open access: yesBrain and Spine
Background: Preoperative knowledge of tumor consistency and the likelihood of gross total resection (GTR) would greatly benefit planning of pituitary adenoma surgery, however, no reliable methods currently exist.

Thermoplastic elastomers filled with GTR

open access: yes, 2018
Rubber is used in a vast number of products, from tyres on vehicles to disposable surgical gloves. Increasingly both manufacturers and legislators are realising that recycling is essential for environmental sustainability and can improve the cost of manufacture.

The General Theory of Regulated Stability (GTRS)

open access: yes
AbstractThis manuscript formalizes the General Theory of Regulated Stability (GTRS), a scale-invariant framework governing the persistence of complex systems. By deriving the α < 1Variational Principle from non-equilibrium thermodynamics and structural topology, weestablish a mathematical link between quantum vacuum fluctuations, ecological ...

Enhanced surface activation of ground tire rubber via the radiolysis of water for effective rubber recycling

open access: yesHeliyon
In this study, we examined the chemical changes occurring in ground tire rubber (GTR) and on its surface as a result of gamma irradiation in water, with low doses of 5, 10, 15, 20, 25, and 30 kGy. To better distinguish the changes the radiation caused in

Microwave devulcanization of Ground Tyre Rubber (GTR) and characterization of various types of GTR

open access: yes, 2015
Three types of ground tyre rubber (GTR) are treated with microwave in order to study the effect of microwave devulcanization. The first one is the standard GTR of truck (A1) and car (A2), mechanically reactivated GTR of truck (B1) and car (B2) and GTR which has been mechanically and chemically devulcanized (C1).
