born in Berlin, Germany, in 1886 1903-1908, studied philosophy and psy. at the Uni.of Edinburgh in Scotland and Uni. of Berlin. 1910, went to work as assistants to Friedrich Schumann at the Psychological Institute in Frankfurt 1924, went to America and worked in Connel Uni., Wisconsin Uni. And Smith College till his death. Koffka introduced it to the United States and systematized Gestalt psychology into a coherent body of theories

The nucleic acids, deoxyribonucleic (DNA) and ribonucleic (RNA) , are, respectively , the molecules that preserve here￾ditary information and that transcribe and translate it in a way that allows the synthesis of all the varied proteins of the cell 25.2 NUCLEOTIDES AND NUCLEOSIDES

The objective of this chapter is to study how money and interest rate is determined in the money and financial market. The money and financial market is the market in which money and various financial assets (such as, bonds and stocks) are exchanged

Our research program involves the design, synthesis, and detailed physical investigation of novel molecular and nanoparticle materials which display unique self-organized hierarchical structures and specific optical, electronic, andor magnetic properties. Emphasis is placed on materials with potential applications in light-emitting devices, optical memory devices, molecular level and single particle level switching devices, and chemosensory devices
