“The importance of recovering waste materials generated by industrialised societies is mainly due to the environmental impact they have, and one of the principal problem areas is tires. In recent years, an enormous amount of tires have been recycled. Metals contained in them have been recovered and the tire particles have been used in diverse applications. A third material that appears in the recovery process is the fibers, which act as reinforcement. Before addressing the possible reuse of these fibers, it is necessary to characterise and identify them. The diverse techniques of thermal analysis allow these fibers to be identified through melt point analysis, the results of which show the presence of polyamide 6 Nutlin-3 chemical structure and 6.6. Moreover, the combination of pyrolysis-gas chromatography/mass spectrometry corroborates the identification made with the techniques previously mentioned and also indicates the presence of certain additives used in the manufacture of tires, such as resorcinol and benzothiazole.

“Background: The purpose of this single-blinded, randomized, controlled trial was to compare the analgesic efficacy of intra-articular injections of bupivacaine or ropivacaine with that of no injection for postoperative pain control after the operative treatment of supracondylar humeral fractures in a pediatric population.
Methods: Subjects (n = 124) were randomized to treatment with 0.25% bupivacaine (Group B) (n = 42), 0.20% ropivacaine (Group R) (n = 39), or no injection (Group C) (n = 43). The opioid doses and the times of administration as well as child-reported pain severity (Faces Pain Scale-Revised) and parent-reported pain severity (Total Quality Pain Management survey) were recorded.
Results: The proportion of subjects who required morphine
and/or fentanyl injections was significantly (p = 0.004) lower in Group B (10%) as compared with Group R LB-100 (36%) and Group C (44%). On the basis of the log-rank test, the opioid-free survival rates were significantly greater in Group B as compared to Groups C and R. Total opioid consumption (morphine equivalent mg/kg) in the first seventy-two hours postoperatively was significantly less in Group B as compared with Group C (mean difference, 0.225; [95% confidence interval (CI), 0.0152 to 0.435]; p = 0.036). Parent-reported pain scores were also significantly lower in Group B as compared with both Group C (mean difference, 1.81 [95% CI, 0.38 to 3.25]; p = 0.014) and Group R (mean difference, 1.66; 95% CI, 0.20 to 3.12; p = 0.027). There were no significant differences across the three groups in terms of self-reported pain. Differences between Groups R and C were not significant for any of the outcome variables.
