Experimental Investigation on Shear and Hardness of Abaca based Hybrid Composites

Present technology development in the area of materials replaces the conventional materials used in automobile and aerospace sector by composite materials due their less weight and bio degradability. This paper aims to fabricate and investigate the mechanical properties of abaca-raffia hybrid composite fabricated by hand layup process. Since, abaca fiber has more strength than other fibers like kenaf, banana and sisal, the composite with this fiber can be suitable replacement material for automotive applications.The properties like double shear and hardnessare evaluated andthe result shows that the double shear properties and hardness of the hybrid composites [GFRP+Abaca+Raffia] is higher than other two combinations. The internal microstructure of the hybrid composites were analysed using Scanning electron microscope (SEM)

The factors affecting the development of the musical performance : A study on the musical performance in Shanghai

The development of musical theatre in china is still in its initial stage, only a few big theatres have the ability of operating musical performance, and at this time, musical theatre is only performed in few big cities in China, like Shanghai and Beijing. The the-sis focuses on the development of musical theatre in Shanghai. As an entertainment ac-tivity and also one of the performing arts, the demand for musical theatre could be affect by many factors like educational background, income and competition from other forms of entertainment activities. There were many previous studies about the performing arts which also focused on the factors like education and income, however, the level of con-tributions of these factors to the development of different forms of performing arts are different. By reviewing related previous literatures and analyzing the data collected from Shanghai Grand Theatre which bases on a meta analysis of previous studies of performing arts, the thesis explores the current situation of the development of the mus-ical performance in Shanghai and studies various factors that affect the demand for musical theatre, as a result, a deeper understanding of how factors like educational background, income, competition among forms of entertainment activities etc. affect the development of musical theatre in Shanghai wish to be provided
