Jockeys are exposed to high risk of head injuries while riding. Therefore, helmets are vital for protection. Carbon fibre is widely used in sports technology due to its mechanical properties. Applying carbon fibre in jockey helmet shells could decrease the risk of fatal head injuries. The aim of the research was to investigate the safety performance of jockey helmet shells made out of carbon fibre. Four different shell types were produced with the same prepreg material. They differ in the number of layers (four or five) and patterns (two and four). Peak deceleration was used to compare the different type of shells through 2-wire drop tests. Gaussian and Mean curvatures of the impact sites were also measured to obtain a better understanding of the impact behaviour. The two-patterned shell with the five layers (2P5) showed the best overall performance during the standard impact test. [ABSTRACT FROM AUTHOR]

This contribution firstly reviews developments in the EU and in the United States on corporate social responsibility and conflict of laws. It concludes with reference to some related themes, in particular on the piercing of the corporate veil and with some remarks on compliance strategy, and compliance reality, for corporations.

The hard shell of a hazelnut is a major waste of the hazelnut industry. The chemical composition, phenolic compounds (total phenolics, tannins and condensed tannins), antioxidant activity (DPPH and ABTS free-radical scavenging assays), and the relationships between phenolic compounds and antioxidant activities of the hazelnut shells from twelve US grown cultivars were investigated to for potential commercial development. Crude fibre accounted for over 85% of total carbohydrate. The shells contained high concentrations of phenolic compounds. Concentrations of phenolic constituents and ABTS•+ -scavenging capacities were significantly higher (P > 0.05) in the Oregon cultivars than their Nebraska counterparts. There were significant positive correlations between ABTS•+ scavenging capacities and the phenolic compounds, whereas DPPH• -scavenging capacity demonstrated a weak negative correlation with ABTS•+ scavenging capacity and the phenolics. The results suggest that hazelnut hard shell may serve as a potential source of natural antioxidants for food applications. [ABSTRACT FROM AUTHOR]
