plastics‚ synthetic fibers like rayon and nylon. Latex from trees such as the rubber tree goes to make tyres‚ tunes and a wide range of rubber goods. Other uses; fruits‚ nuts and spices are gathered from the forest. Many medicinal plants such as camphor‚ cinchona‚ coca (from which the drug cocaine is extracted) also come from the forests. Cork from the thick bark of the cork oak is stripped for making bottling cork. Forests help to conserve soil by preventing rapid runoff of water after heavy

Bridget Biddy Mason Bridget “Biddy” Mason was born on August 15‚ 1818 as a slave to Robert Marion Smith and Rebecca Crosby Smith in Hancock‚ Georgia. In 1847 Robert Smith‚ Biddy’s owner‚ became a Mormon then packed up all of his belongs to move to Utah. On the journey Biddy was forced to herd the cattle‚ cook meals‚ midwife and take care of her own children‚ Ellen‚ Ann and Harriet. Then in 1851 Smith again packed up his belongs and moved to San Bernardino‚ California to join another Mormon community

Chinese (A.D 618-907) : Ice cream dates back to China’s T’ang period‚ probably a dish for the country’s rulers. King T’ang of Shang kept 94 "ice men" on hand to lug ice to the palace to make a dish made of koumiss (heated‚ fermented milk)‚ flour‚ and camphor.

Hairy insect legs Slippery camphor laurel leaves The salty taste of fish and chips on my tongue And the watery melting of iceblocks. And all I remember. A veranda shaded by grape vines‚ Where I stepped off the edge and flew Like Superman.

antifungal and antibacterial potentials of volatile oils and oleoresin of Cinnamomum zeylanicum Blume (leaf and bark) were investigated in the present study. The oleoresins have shown excellent activity for the inhibition of primary and secondary oxidation products in mustard oil added at the concentration of 0.02% which were evaluated using peroxide‚ thiobarbituric acid‚ p-anisidine and carbonyl values. Moreover‚ it was further supported by other complementary antioxidant assays such as ferric thiocyanate

Electrochemical Series - Define oxidation and reduction in term of loss and gain of oxygen; loss and gain of electrons and change in oxidation state (number). • Oxidation is the loss of electrons; an increase in oxidation state or a gain in oxygen by a molecule‚ atom‚ or ion. • Reduction is the gain of electrons; a decrease in oxidation state or a loss of oxygen by a molecule‚ atom‚ or ion. • OIL RIG (Oxidation is Loss‚ Reduction is Gain) - Rules for assigning the oxidation numbers of an atom. •

UNIT 5 – ELECTROCHEMISTRY Chapter 9 – Electric Cells 9.1 – Oxidation and Reduction * The term reduction came to be associated with producing metals from their compounds. * Ex. Fe2O3(s) + 3CO(g) 2Fe(s) + 3CO2 * Another substance‚ called a reducing agent causes or promotes the reduction of a metal compound to an elemental metal. In this example‚ it is CO. * Corrosion‚ including the rusting of metals‚ is now understood

HOW ARE REDOX REACTIONS DIFFERENT? Redox is the term used to label reactions in which the acceptance of an electron (reduction) by a material is matched with the donation of an electron (oxidation). A large number of the reactions already mentioned in the Reactions chapter are redox reactions. Synthesis reactions are also redox reactions if there is an exchange of electrons to make an ionic bond. If chlorine gas is added to sodium metal to make sodium chloride‚ the sodium has donated an electron
