Strawberries have a very short post-harvest life mostly due to their relatively high water content, intense metabolic activity and susceptibility to microbial rot. Antimicrobial low-density polyethylene nanocomposite films containing ZnO nanoparticles at different mass fractions were prepared by melt mixing and followed by compression moulding using a hot press machine. Fresh strawberries were ...

D. Nowak, M. Stachowicz, K. Granat, M. Pigiel. Wroclaw University of Technology, Wroclaw, Poland The paper presents a semi-industrial reactor designed for microwave utilization of waste moulds and cores made of moulding sands prepared in furane resin technology. It was found that a possibility exists of eff ective incinerating this way prepared residues of cores separated from moulding sands or...

Bio-reduction of composite materials is the modern approach to facilitate researchers avoid toxic chemical exposure during reduction process. In this study, green graphene oxide using Abutilon indicum (Tamil name: Thuthi) plant leaves extracted from various solvents were used as filler material (0.3, 0.6 and 1 wt.%) in glass fibre epoxy composite. Compression moulding process was adopted fabric...

For automotive plastic parts, mostly used for interior assemblies, there is a clear demand of an increased accuracy of the simulation model. One crucial input for the simulation model is the correct material data. Based on test data, it is known that the dynamic material properties of a plastic part can differ significantly from the material data given in the data sheet (which is based on a spe...

Due to good density specific mechanical properties and low carbon footprint, natural fibre-reinforced plastic composites made from fleeces felts are frequently used as automotive interior parts. The industry targets further mass reduction. Following a biomimetic technology-pull approach, polypropylene plates with improved lightweight potential were produced using compression moulding. Best resu...

Results 1) The average initial angle is: 28,19 (+-9,21) for thoracic, 28,11 (+-9,34) for thoraco-lumbar and 25,86 (+-7,04) for lumbar curves. 2) The angular reducibility is 54 % in braces for the thoracic curvatures, 69 % for the thoraco-lumbar curvatures and of 73 % for the lumbar curvatures, which corresponds to the usual results of the Lyon management. If we select curves of 30° and more the...
