The present work investigates the mechanical properties and tribological behavior of Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite

Age of Mechanical Reproduction’: how has the reproduction of images changed the development of art? Identify three works of your choice to support your argument. This essay will start from Walter Benjamin’s consideration about the impact of mechanical reproduction of art as revolutionizing its social function and will describe the noticeable validity of his theory in the contemporary world. By introducing three artworks that belong to different historical periods‚ namely‚ the ‘Mechanical Head’

One thing that is clearly evident is that human beings have consistently developed new forms of solidarity as we have evolved from roaming bands of hunters and gatherers to a digital society with swiftly eroding national borders. Organisations such as Médecins sans Frontières‚ The Red Cross‚ and Amnesty international were created as platforms of international solidarity (Baglioni 2001‚ p. 224). For these organisations‚ all that mattered was helping people in need‚ wherever they were and utilising

Doctor Gary Hall Differential Equations March 2013 Differential Equations in Mechanical Engineering Often times college students question the courses they are required to take and the relevance they have to their intended career. As engineers and scientists we are taught‚ and even “wired” in a way‚ to question things through-out our lives. We question the way things work‚ such as the way the shocks in our car work to give us a smooth ride back and forth to school‚ or what really happens to an

Our human body can experience or undergo a lot of stress or forces through the senses‚ one of the experiences are the shock‚ vibration and even impact on the human body itself. This act of forces can be effects to the human body if the forces apply are beyond the structure human body

power in Eastern Europe be blamed on the Solidarity movement? I think that the Solidarity movement played a key role in the collapse of the Soviet Union‚ because it not only influenced the biggest country in the Eastern Block‚ (Poland which shared a long border with the USSR and previously served as a corridor for attack on the Soviet Union)‚ it also managed to attain over 10 million members and supporters nationwide. Since the Solidarity movement or Solidarity itself was a trade union‚ it had great
