Introduction Mosquito coils are widely used as mosquito repellent. The major active ingredients of most mosquito coils are pyrethrins‚ accounting for about 0.3 – 0.4% of the coil mass. When a Mosquito coil is burnt‚ the insecticides evaporate (pyrethrin‚ PAH‚ aldehyde etc.) with smoke‚ which prevent the mosquito from entering the room and harm those already in the room. The remaining components of mosquito coils include organic fillers‚ binders‚ dyes and other additives capable of burning well without

”The share of organic and natural cosmetics in the $270 billion global cosmetic market is growing at a fast pace.” As people are becoming more and more conscious of the negative side effects of extended use and exposure to chemical cosmetics so too has the cosmetics industry. Cosmetics normally use aromatic hydrocarbons that are derived from petroleum which have been proven to show long term side effects on the skin. While the idea of organic cosmetics is not new a company as well known as M.A.C

imaginative grouping of human evil that is addressed into nine circles that descend into the depths of hell.

For example‚ a sin in the Eighth Circle of Hell‚ bribe‚ would be considered worse than a sin in the Sixth Circle of Hell‚ murder. To understand this‚ one must realize that Dante followed very strict Christian values during the time that this book was written. Throughout his decent

Unit 1: Biochemistry Review Chemical Bonding Three types of bonds Ionic bond: 2 oppositely charged atoms (Na and Cl) Polar covalent: Unequally shared electrons (H and O) Non polar covalent: Equally shared electrons (C and C) or similar electronegativity Electronegativity and chemical bonding Electronegativity is a measure of the strength in which an atom can attract electrons. A difference of < 0. 5 is non polar covalent bond A difference of 0.5 – 1.7 is polar covalent bond A difference of > 1

Is Organic Food Worth It? Organic farming began in the late 1940’s in the United States‚ and in recent years it has seen a dramatic increase in popularity. The sales of organic food have been increasing by about 20 percent a year over the past decade.
