This course works will focus on the basics of the nano-scale materials. Historical perspective on nanomaterials, classifications & syntheses techniques will be discussed in detail. The session will also cover polymeric nanoparticles: core-shell concepts, polymer caped metal nanoparticles, controlling the size and composition of the metallic cores of nanoparticles and functionalized metal nanoparticles arrays on surfaces.
Recent studies of 'duration of untreated psychosis' (DUP) indicate that some patients remain untreated in the community for some time. Considerable emphasis has been placed on reducing the DUP. However, most studies investigating DUP have been conducted in Western countries, where well-developed primary care systems are available. This study aims to describe DUP and its association with both demographic factors and pathways to care in Riyadh, Saudi Arabia.
Abstract. This work is devoted to calculate bound states in the two-electron atoms. The
separation of variables has carried out in hyper spherical coordinate system (R, θ, α ). Assuming
collective motion of the electrons, where the hper angle (α ~ π/4) and (θ ~ π). The separation of
the rotational variables leads to system of differential equations with more simple form as
compared with non restricted motion. Energy of doubly excited Pe and D0 states are calculated
