In this paper, the f(alpha) conversion functions for random scission mechanisms have been proposed to allow for the construction of generalized master plots suitable for these kinds of mechanisms. The master plots have been validated by their application to simulated data and to the thermal degradation of poly(butylene terephthalate), polyethylene, and poly(tetrafluoroethylene).

Background: Whether elderly patients with aortic root or ascending aortic aneurysm (ATAA) would benefit from the new surgical size threshold of 5.0 cm is unknown. This study aimed to evaluate the natural history of ATAA in elderly patients and to compare long-term outcomes of those who underwent initial surveillance versus surgery.

Intraocular pressure (IOP) readings using three different methods (Goldmann applanation tonometry (GAT), Corvis ST, and iCare) were compared in patients who underwent penetrating keratoplasty (PK). : An observational cross-sectional study with prospective recruitment of patients was conducted. IOP measurements were acquired using GAT, iCare, and Corvis (including both uncorrected IOP (CVS-IOP) and biomechanical IOP (bIOP)), and the agreement among methods was analyzed using Bland-Altman plots.

Background: Evidence-based practice (EBP) entails utilizing the most up-to-date information to inform clinical decisions. Healthcare professionals at all levels are encouraged to integrate the latest research evidence to ensure high-quality care. In Ethiopia, there is a lack of comprehensive, nationally representative data on the prevalence of EBP among healthcare workers.

Co-pyrolysis behaviors, kinetics, and thermodynamic parameters of petrochemical sludge (PS), lignite (HL), and pine wood (PW) were investigated via fixed-bed reactor experiments and thermogravimetric analysis. Fixed-bed experiments showed H and CO were main gases from PS, HL, and blends, CO from PW and PS, and CO and CH from PS and HL. Thermal analysis indicated that ternary blends' de-volatilization had two parts dominated by PW and HL, respectively.

The influence of Acrylate Styrene Acrylonitrile (ASA) and ASA/nanosilica (ASA/Si) additives was investigated by using a dynamic shear rheometer (DSR). Firstly, an ASA polymer was blended with the virgin asphalt binder at two different concentrations (3% ASA and 5% ASA). After observing that 5% ASA was the optimum concentration for modification, nanosilica particles were further incorporated into the 5% ASA-modified asphalt binder with two different percentages (5% ASA 3%Si; 5% ASA 5%Si).
