Due to the demand from society for the consumption of ecological polymeric materials, one of the polymers that have satisfied this request is the poly (lactic acid) (PLA). This polymer is derived from renewable resources, it is recyclable and biodegradable. It presents a good understanding between the promising properties and the cost. However, a route to increase the mechanical properties and reduce the cost of PLA is the elaboration of PLA based biocomposites by using fillers from natural waste. In this work, The effect of Typha content on the morphological, rheological, thermal and mechanical properties of PLA matrix was studied. Four formulations were produced with different mass concentrations. The results showed an increase in the viscoelastic properties, as a function of the Typha stem powder concentration. The DSC analysis showed an increase in the crystallinity rate of the various composites confirming the nucleating effect provided by the filler. TGA analysis indicated a decrease in the decomposition temperature of the composites. Mechanical tensile tests have shown a significant improvement in the mechanical properties mainly for the samples containing 45% (w/w) of Typha powder.

Wood polymer composites (WPCs) were made with pine and polypropylene matrix (PP). The composites were produced by melt blending in a Brabender at 180°C. Characterization of the samples, with the aid of scanning electron microscopy supplemented by microscope photography, showed an improved dispersion of wood in the polymeric material in presence of polypropylene grafted with maleic anhydride (MAPP) or nanoclay. The use of the MAPP instead of clay seems to have enhanced the level of crystallinity in the composites for the same levels of wood loading and also accelerates the crystallization. Melt rheological measurements of neat PP and PP-wood composites were carried out at 180°C with an ARES Rheometer scientific mechanical spectrometer in oscillatory frequency. All the composites materials exhibit viscoelastic values greater than those for neat PP. The samples containing MAPP as comptabilizer show the higher Newtonian viscosity, however, the addition of a small concentration of nanoparticles like nanoclays does not improve the resulting melt viscoelastic behavior of the composite.

立体视觉不仅指对静态深度信息的感知,也包括对物体在三维空间中的运动方向的判断.本研究记录了人眼对于动态随机点图运动方向的辨别能力以及视觉训练在提高对动态信息分辨能力的作用.实验结果表明,对于没有任何相关经验的视力正常的受试者,很难分辨出动态随机点的深度运动方向,而视觉训练可以大大提高人眼对物体深度运动方向判断的敏感度.此外,这种视觉训练所达到的效果具有较长时间的持续性(至少6个月).这种通过视觉训练提高受试者对立体运动信息敏感度的方式,为立体视觉相关的实验和研究提供了新的视角.

The thesis of this paper is a refutation of Wale Adenuga’s claim that the human person is nothing but a pencil in the hand of the *** paper adopts a hermeneutical approach from an Igbo conception of the human *** posits that in Igbo worldview,the human person occupies a central position because mankind is at the very centre of existence;hence is seen as the goodness or beauty of life(mma ndu)or the good or beauty that is(mma du{di}).While conceding the plausibility of a pencil being capable of doing great things when guided by a good hand,the paper maintains that from the point of view of Igbo ontology,the human person is distinctively more than a mere pencil in the hand of the creator because mankind is endowed with high intellectual capacity,freedom,and creativity on the basis of which it seen as both the beauty that is(mma du)or the beauty or goodness of life(mma ndu).Thus,the paper concludes that the fact that the human person is endowed with these attributes provides rational grounds to render Wale Adenuga’s concept of the human person as“nothing but a pencil in the hand of the creator”futile.

The thermal, rheological and morphological properties of composite biomaterials made with mixture of high density polyethylene and typha rod powder (RD) were evaluated. The dynamic mechanical behavior of the samples was studied with 25%, 35% and 45% typha stem powder concentrations. The viscoelastic properties are mainly related to the nature of the polymer and the typha stem powder. Storage (G') and loss (G') moduli increased significantly, depending on the amount of powder in the molten mixture. After a viscosity increase was noticed in low frequency, it decreased in high frequencies, which demonstrates the pseudo-plasticity effect. Morphological and thermal characterization results have shown the dispersion state of the powder and its ability to modify the kinetics crystallization of biocomposites.
