OIL PAINTINGS One of the images that I’m most fond of is the “Madonna and Child with the Chancellor Rolin” by Jan and Eck. This piece is one my favorites because it uses oil. When using oil the images of the paintings seem to realistically speak to me. This particular painting enables both fusion of tones and crisp effects and is unsurpassed for textural variation. The standard consistency of oil paint is a smooth‚ buttery paste. In this scene it depicts the Virgin crowned by a hovering Angel while

Synthesis of Aspirin from Oil of Wintergreen Objectives: In this experiment‚ the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. The solution is then refluxed which means that the solution will be boiled in a base‚ then condensed in a condenser. This replaces the carbon on the ester at carbon 1‚ with an oxygen atom which will have an ionic bond with a sodium anion. This yields sodium salicylate which will be acidified in methanol

of Biodiesel by Enzymatic Transesterification: using Waste Cooking Oil as feedstock and Candida Antarctica Lipase B as Biocatalyst. CHAPTER 1 INTRODUCTON The high cost of bio-diesel‚ compared to petroleum-based diesel‚ is a major barrier to its commercialization. It has been reported that 60-90% of bio-diesel cost arises from the cost of the feedstock oil (C.C. Lai et al.‚ 2005). Studies showed the potential of waste-cooking oil (WCO) as a material for biodiesel production (Sulaiman Al-Zuhair

Title: Oil‚ Fire and Crayons Abstract: This study tries to find out the possibility of the used cooking oil as an additive component of candle. This study aims to produce a low-priced but high-quality candle by using used cooking oil as a major component. The following materials: 500 mL used cooking oil‚ 1 kg paraffin wax‚ cotton thread cut into 5 inches long‚ serves as‚ wick‚ crayons in different colors ‚a can (like the can of century tuna)‚ beaker‚ barbecue stick‚ plastic molder.

What’s an Investigatory Project Exactly? An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you’ve created your hypothesis or proposal‚ you can conduct a controlled experiment using the scientific method to arrive at a conclusion. What Kind of Investigatory Projects Are There? In order to conduct a great investigatory experiment‚ you have to ask an interesting

EXTRACTING AND PURIFYING GENOMIC DNA FROM A RAT LIVER FOR ELECTROPHORESIS Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Along with RNA and proteins‚ DNA is one of the three major macromolecules essential for all known forms of life. Genomic DNA is the DNA that holds the complete set of genetic data for an organism. In humans‚ the genomic DNA spans 46 chromosomes‚ providing a complete

The natural fats and oil are mixtures of glycerides of fatty acids. Fats and oils are naturally occurring organic compounds which belong to a large group of water insoluble substances called lipids. Lipids are relatively non-polar molecules‚ they can be pulled out of a sample using relatively non-polar

It shows the couple dancing in a rainstorm‚ one person holding an umbrella over the couple‚ with the CANOPY protecting them from rain. Another person running for cover from the rain. It seems as if the dancing couple is completely ignorant of the rain. The artist isn’t talking about a light
