Abstract In this study, compatibilized thermoplastic elastomers (TPE) based on recycled high-density polyethylene (HDPE) and high ground tire rubber (GTR) content (70, 80 90 wt%) were prepared by twin-screw extrusion followed injection molding. The main objective of the work was to use three different compatibilizers compare their efficiency: ethylene-octene copolymer (Engage 8180), styrene-ethylene-butylene-styrene grafted with maleic anhydride (SEBS-g-MA) (Kraton FG1901X) a trans-polyoctenamer (Vestenamer 8012). A morphological analysis showed that addition compatibilizer produced more homogeneous structures, significantly improving mechanical performance compared uncompatibilized counterparts. This modification had direct effect all properties, especially tensile properties which evaluated at crosshead speeds (10, 50, 100 500 mm/min) better see differences in interfacial state. High elongations break exceeding % for highly filled blends (up wt% GTR) Kraton FG1901X obtained, highlighting superior compatibility efficiency. general, adding GTR PE elastic TPE. Increasing concentration led lower modulus (from 300 MPa R-PE 50 70 GTR). conclusion molding TPE (above %) only possible compatibilizers. Nevertheless, best produce obtained using probably due its functionality (maleic anhydride, MA) leading interactions between phases.

Evaluation of commuter perception and optimization of public transit routes in Hyderabad using TOD applications

Mehran University Research Journal of Engineering and Technology, Journal Year: 2025, Volume and Issue: 44(2), P. 71 - 84

Published: April 9, 2025

The accessibility, efficiency, and convenience of public transit in Hyderabad are significantly hindered by inadequate infrastructure, overcrowding, insufficient funding, inconsistent service, traffic congestion, limited coverage. Urban engineers/urban planners widely recognize the Transit-Oriented Development (TOD) applications as an effective strategy for promoting maintainable urban growth. TOD focuses on situating populations near transportation hubs to reduce dependence private vehicles. Hyderabad's system (buses trains) currently falls short meeting commuter needs due absence principles, leading increased vehicle usage, air pollution. This study aims evaluate perceptions regarding facilities' availability. It illustrates service area coverage existing Transit route network based walkable distances converted travel times using ArcGIS. Data was collected extensive questionnaire survey involving 400 respondents, selected Taro technique. Route information gathered from Regional Transportation Authority (RTA) on-site surveys detailing available routes. data analyzed SPSS software, employing statistical methods such Chi-Square tests, correlation analysis, normality checks, ANOVA. identified catchment areas routes Hyderabad, emphasizing regions where passengers have easy access alignment with applications.

This paper presents the results of naturally aspirated compression ignition (CI) internal combustion engine (ICE) bench tests fuels in form a blend diesel oil with recycled (RF) tire pyrolysis (TPO) as an admixture content pyrolytic being 10% m/m (D90+RF10). The relate to reference conditions which is fed pure (D100). experiment included evaluation performance and determination selected substances exhaust gas for brake-set loads equal 5 Nm, 10 15 20 Nm. For each load, operating parameters emissions components were recorded at preset speeds range 1400–2400 rpm load. hourly fuel consumption temperature determined. contents CO2, CO, HC measured. D90+RF10 increased by 56%, CO2 21.7% higher low loads. addition sulfur-containing resulted SOx emissions. show suitability possibility using it fossil fuels.
