    Introduction Cytometry is a combination of two greek words: cyto- cell‚ and metry - measurement. So cyto-metry is about making cell measurements. To elaborate‚ flow cytometry is a technique for analysing particles (cells in this case) which are suspended in a fluid stream by flowing the cells past an interrogation point. A light source is directed on to a hydrodynamically focused stream to create a zone for interrogation. As cells flow through this interrogation zone they scatter the light‚ at this

    a load of 1.5 tonnes along I-beam of 4 metres long. The research that we did was mainly on existing trolley cranes and the configurations of these cranes which allowed us to familiarize ourselves with what the crane does and how it works. The way that the crane operates is by having a person pull a chain. This chain is connected to a drive shaft which in turn is connected to a pinion and two wheels. These wheels allow the crane to move horizontally along the I-beam whilst sustaining a load.
