wind streams. The repercussions of the disaster are only now being better understood today. The reactor type at Chernobyl was a RBMK type reactor. The reactor is a vertically oriented reactor that uses graphite as an insulator which also caused problems due to the combustibility of the graphite that was used. "The reactor fuel is zirconium alloy clad uranium oxide enriched to 2.0% U-235" (Mosey). The RBMK reactor also has two 500MWt reactors which operate safely at 100% power of 1000MWt. "Reactor

Vermeer and Rembrandt‚ his themes lie more within the realms of surrealism and visionary art than traditional painting. • • • • • All paintings are 180 grams A4 inkjet paper sheets‚ hand painted on with mainly drawing inks. Also used: bistre and graphite. The paper consists of 3 layers: an emulsion‚ a plastic coating and a paper under layer. The emulsion swells up when in contact with the inks and will slowly dry up. This process is repeated with each thin layer of ink that is added. The plastic

1. Ingres choice of materials influences the character of his drawing‚ by the use of lightness and refinement in the drawing. The graphite pencil and smooth paper that were used in this drawing‚ allowed Ingres to cope with repeated erasing when needed‚ to bring a moderate degree of realism in his character. Ingres line work is rhythmically repeated. The contour lines on the left arm‚ on the dress are parallel to the lines on the right arm‚ of the dress. Looking at the lines of the back of the woman’s
