.... and nitrogen dioxide, in the atmosphere, in the presence of sunlight. This reaction is called a photochemical reaction, because sunlight is required. The product is known as smog. The notorious brownish color of smog is due to nitrogen dioxide of the mixture. Increased temperature stimulate the reaction, which is why ozone conditions are worse in the summer. It is an oxidant, meaning it takes electrons away from other molecules, and disrupts key structures in cells by starting chain reactions. Ozone is a serious national problem. Half of the largest urban ar .....

.... the birth of Christ and told of a boy named Arraign, who was cast into the sea by pirates. A dolphin came to his rescue and carried the boy home to Greece on his back. Plutocrat wrote Thathos, Odysseus' son, was saved from drowning as a young child through the aid of a dolphin. A roman scholar Plink the Elder, who lived in AD 23-69, wrote about a boy named Hermias. Hermias had many encounters with a friendly dolphin which he would except rides from. One day Hermias was thrown off the dolphins back by a sudden storm and drowned in the sea. The dolphin brought the boy .....

.... "Scientific methodology in this field dates from the foundation in London of the Society for Psychical Research (1882) which sought to distinguish psychic phenomena from spiritism and to investigate mediums and their activities." (http://wheel.ucdavis.edu) The research started over one hundred years ago and their goal was to understand why unexplainable phenomena was occurring. "Modern experiments, notably at Duke University under Joseph Banks Rhine, in Britain at the Society for Psychical Research and in Russian research labs, have concentrated principally on extrasensory perc .....

.... common of the High Cloud group. They are composed entirely of ice and consist of long, thin, wispy streamers. They are commonly known as "mare's tails" because of their appearance. Cirrus clouds are usually white and predict fair weather. Cirrostratus clouds, belonging to the high cloud group, are sheet like thin clouds that usually cover the entire sky. The sun or moon can shine through Cirrostratus clouds. Sometimes, the sun or moon will appear to have a halo around it when in the presence of Cirrostratus. The ice crystals from the cloud refracts the light from the sun or m .....

.... orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free to move in response to an applied voltage or electric field. The fewer conduction ele .....

.... contribute to the occurrence of an asthma attack. The review of asthma in Victoria (1988) by the Asthma Foundation of Victoria outlined infection, exercise, climatic conditions, exposure to airborne irritants and emotional upsets as the main trigger factors. However, doctors use a general classification to identify a patients pattern of asthma…classifying people who experience some symptoms of asthma on most days as having a chronic asthma condition. The classification system also extends to the categories of children, occupational asthma and asthma in later life. .....

.... and generally out of place. In fact the reverse is true. During a recent stay on the Falkland Islands, a Canadian researcher discovered that penguins are able to recognize individuals and navigate the rocky terrain on which they live quite well. Long of body and short of leg, they probably poke their heads forward as an aid to balance. And as for looking at the ground, they're merely-like us-keeping an eye on where they're going. The human eye is adapted for aerial vision, which is why scuba divers-or even you and I in the local swimming pool-must wear goggles or a face .....

.... THE THEORY OF BIOLOGICAL EVOLUTION .... 45 ALTERNATE EXPLANATIONS OF BEING ........................... 47 CONCLUSIONS ............................................... 48 INTRODUCTION Theories explaining biological evolution have been bandied about since the ancient Greeks, but it was not until the Enlightment of the 18th century that widespread acceptance and development of this theory emerged. In the mid 19th century english naturalist Charles Darwin - who has been called the "father of evolution" - conceived of the most comprehensive findings about organic .....
