the effect of Bagasse ash （BAp） particle reinforcement on the wear behavior of Al-Cu- Mg alloy has been studied. Bagasse ash particles were varied from 0 wt pct-10 wt pct with interval of 2 wt pct. Unlubricated pin-on disc t.s.s were conducted to examine the wear behaviour of the aluminium alloy/Bagasse ash particulate composit.s. the t.s.s were conducted at varying loads, from 5 to 20 N and sliding speeds of 1.26 m/s, 2.51 m/s, 3.77 m/s and 5.02 m/s for a constant.s.iding distance of 5000 m. the results showed that the wear rat.s.of the A1-Cu-Mg/BAp composit.s.are lower than that of the matrix alloy and further decrease with increasing Bagasse ash content. Wear rate increases as the sliding speed and applied load increase. the microstructure of the worn surface revealed that a large amount of plastic deformation appeared on the surface of the unreinforced alloy. While Bagasse ash reinforced Al-Cu-Mg alloy showed worn out.s.rface that is not.s.ooth, and grooves, scratches and parallel lines were observed. A combination of adhesion and delamination wear was in operation. these results show that improve wear properties is achievable for the aluminium alloy by the addition of Bagasse ash particles as reinforcement material.

Let D be a domain in Cn. It is known that if D is a simply connected bounded domain in C with spherical real analytic boundary D, then every local biholomorphic map at boundary as above extends to a biholomorphic map from D onto the unit ball in Cn. As a consequence, a local biholomorphic map between D1 and D2 where D1 and D2 are simply connected domains in Cn with spherical real analytic boundaries can extend to a global biholomorphic map from D1 onto D2. If the boundary is algebraic, the simply connected condition in the above result can be dropped. In this note, we show that the above phenomenon is no longer true if domains are in algebraic varieties with isolated singularities.
