Zaha Hadid and the Russians

        Hi Hi,
I am a graphic design student at the Ravensbourne College o.D.a.C. in London.
My next essay deals with
       1 Zaha Hadids Architecture
       2 her drawings and sketches
       3 the influence of the Russian Avantgarde of the 1920s on her work

                DOES anybody have ideas and information
                about some of these aspects?
                ANY interesting books or articles about it?
                (Especially on Suprematism ?!)

        thank you very much in advance, bye:  hilla
