Sansui-ga is a form of Japanese monochrome landscape paintings‚ the preferred genre among Zen painters in the 14th-16th century. Sansui-ga painting is done in Chinese-inspired sumi-e or suiboku-ga‚ an ink wash painting style‚ which uses black ink in various concentrations.

(FAs) can ultimately be degraded through different pathways which include alpha‚ beta‚ and omega-oxidation. Alpha-oxidation occurs at carbon 2 of the chain‚ b-oxidation at C3‚ and omega-oxidation at methyl end of the fatty acid. The location of each mechanism also differs as alpha- oxidation occurs in peroxisomes only‚ beta-oxidation can take place in both peroxisomes and mitochondria. Omega-oxidation occurs in the endoplasmic reticulum of the various tissues. The importance of the differentiation

Once I had written the dream‚ I thought about it trying to memorize minutiae‚ then I drew the landscape then I added more detail to give it a meaning. Afterwards I generated the colors according to the impressionist movement inspired by Mary Cassatt painting “Poppies in a field” and then I used them in a playful manner. I thought about what I wanted to paint‚ with the sense of the texture and the color‚ I mixed the palette‚ and then I filled in the objects. After that with different shades of the base

cloth goes through about 20 washes. The specialty of Kalamkari paintings is that after the long tedious process‚ when the painting is completed‚ the finished products look rich. Even though the colours used are bright but the final look of the art is classy and not gaudy. The textile looks better and better with every wash; and the designs stand out even better next to the background.

8.07 Work File: Oxidation Reduction Reactions 1. What is the difference between an oxidizing agent and a reducing agent? The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons‚ being negative‚ reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons‚ being

attention on spaces with large amounts of light and or shade rather than focusing on the details as other often would. This is what lead to majority of his creations to be worked in with layers. Essentially‚ the first layer was the basics needed for the painting as the second carved away shading and provided more details and texture along with correcting any defects that presented themselves. The last layer was used for finishing touches such as blending colors or smoothing the lines to make them more realistic
