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

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 the GTR and the surface activation of the GTR caused by the irradiated water, we also performed radiation treatments in an inert atmosphere. We mixed the treated GTRs with fresh rubber, and after vulcanization, investigated the mechanical properties and conducted dose optimization.

Oxidation and mineralization rates of harmful organic chemicals in hydroxyl radical induced reactions.

In most of advanced oxidation processes (AOPs) used to destroy harmful organic chemicals in water/wastewater hydroxyl radical (OH) reactions oxidize (increasing the oxygen/carbon ratio in the molecules) and mineralize (transforming them to inorganic molecules, HO, CO, etc.) these contaminants. In this paper, we used the radiolysis of water to produce OH and characterised the rate of oxidation and mineralization by the dose dependences of the Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) content values.

A Single Injection of Platelet-rich Plasma Injection for the Treatment of Stress Urinary Incontinence in Females: A Randomized Placebo-controlled Trial.

Objective: To determine the efficacy of a single injection of platelet-rich plasma (PRP) into the anterior vaginal wall at the mid-urethra compared to placebo, as there is emerging evidence that PRP may help treat female stress urinary incontinence (SUI).

Methods: This was a single-blind, randomized, placebo-controlled clinical trial at a single institution. Females with bothersome, demonstrable stress-predominant urinary incontinence were enrolled.
