established this subfield of IR as the intellectual response to a major change in the international system. Since then‚ argues Benjamin Jerry Cohen‚ IPE has ‘normalized’ and now needs to confront again a changing international system. In this Talk‚ he – amongst others – explains how IPE might confront a changing world‚ how serious ‘currency wars’ are and the current global financial crisis. What is‚ according to you‚ the biggest challenge / principal debate in current IR? What is your position

The IR spectrum in KBr was a great way to compare the library spectrum to the crude and recrystallized Phenacetin. The KBr is a compound that does not show up in the spectrum‚ only the crude and recrystallized Phenacetin show. In this experiment‚ the crude had an 87.17% match to the library. In the recrystallized Phenacetin‚ the IR spectrum was taken twice due to the amount of KBr used in the pellet. The first recrystallized spectrum had a 68% match to the library spectrum. That not being

Indoor Positioning using Infrastructure Nicolas Constantinou January 8‚ 2013 1 Abstract Outdoor positioning has proved to be very functional during the years‚ recently indoor positioning systems which I will be referred to as IPSs have been designed to provide location information of persons and devices. Numerous IPSs are being developed using different infrastructure so the best solution for every situation can be found. This paper gives information and talks about the different IPSs

involved protecting the ketone of ethyl acetoacetate with a ketal group‚ followed by preparation and reaction with Grignard‚ then purification by extraction and recrystallization. The yield was 78.5%‚ but there are impurities present suggested by 1H-NMR‚ IR‚ and TLC. However‚ the results do indicate the desired hydroxyketone was formed. Introduction: The purpose of this multi-step lab was to synthesize 4-hydroxy-4‚4-diphenylbutan-2-one from ethyl acetoacetate. The Grignard reaction is widely used
