the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...

A two-stage reactor system consisting of co-pyrolysis biomass and plastic in the 1st stage catalytic upgrading (zeolite ZSM-5 catalyst) derived pyrolysis gases 2nd was used to investigate yield composition product bio-oil. Biomass waste wood plastics form high density polyethylene, low polypropylene, polystyrene polyethylene terephthalate were as feedstock. The addition with co-pyrolysis-cataly...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...

PURPOSE To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E (polypropylene mesh); and Group U (polypropylene/poliglecaprone mesh). The animals in Groups E and U had a standard muscular and aponeurotic de...

Transient electronics are becoming a hot topic due to the rapid development of bioelectronics, self-destructive devices and environmental sensors. This letter reports a novel scheme for triggering degradation of 250 μm-thick Mg target using acetic acid regarding transient electronics applications. The triggered transience has also been demonstrated using commercial vinegar. To achieve programma...

Abstract The present work deals with the chemical recycling of waste polypropylene via thermocatalytic pyrolysis over HZSM‐5 zeolite catalysts. main aim was to systematically investigate influence reactor configuration, acidity, wastes, obtained from different sources, as well catalyst regeneration on product distribution. It demonstrated that configuration and acid site density catalysts stron...
