Modeling and simulation of welded joints of SS304H & P91 Steels: A Review [PDF]
E3S Web of ConferencesMost of the structures are fabricated by welded joints in various manufacturing units because of low cost and high strength. Welding process is largely used in almost all manufacturing units. Welded joints usually subject to welding deformation patterns.

Planetary nebulae in the inner Milky Way: new abundances [PDF]
, 2009 The study of planetary nebulae in the inner-disk and bulge gives important information on the chemical abundances of elements such as He, N, O, Ar, Ne, and on the evolution of these abundances, which is associated with the evolution of intermediate-mass ...
