quickly, wear out rapidly, resulting in increased cutting forces, higher surface roughness, shorter tool life and lowers the dimensional sensitiveness of work material. Different methods have been reported to protect cutting tool from the generated heat during machining operations. The selection of coated cutting tools is an expensive alternative and generally it is a suitable approach for machining hard materials. Another alternative is to apply cutting fluids in machining operation. Cutting fluids

Cancer Therapy.’ Nature Reviews Cancer, 2 (3), pp. 188-200. Anthracycline antibiotics are also considered as cytotoxic. They harm DNA by introducing a drug molecule between the bases of the DNA strands or block topoisomerase enzymes and radical generation. Topoisomerases catalyse DNA supercoiling (Hurley, 2002). Blocking these enzymes will disrupt DNA. Doxorubicin (Figure 3) is a non-specific DNA-intercalating drug. It is very effective since it is more selective towards cancer cells than normal

1 1. INTRODUCTION 1.1 PROBLEM STATEMENT The purpose of this project is to identify the effect that surface modifications have on the urban heat island phenomenon and related ozone problem in the metropolitan area of Chicago, IL. The basic hypothesis is that urban, summertime temperatures can be significantly lowered by increasing the vegetative landscape cover and enhancing the solar reflectivity of paved and roofed surfaces within an urban area. It is proposed that in addition to a decrease in
