If a delay in child’s walking occurs, the spine should be monitored closely for signs of gibbous formation. In infancy, hypercephalus can occur. Infants head circumference should be monitored close . Monthly checks of head circumference must be monitored. Radiologic studies are indicated if head circumference raises to disproportionately, or if symptoms of hydrocephalus. Child’s pediatrician should have a copy of head circumference curves for children with . Radiologic procedures for dwarfism include he ...

... exploration. Advancements in rocketry after World War II enabled our machines to break the grip of Earth's gravity and travel to the Moon and to other planets. The United States has sent automated spacecraft, then human-crewed expeditions, to explore the Moon. Our automated machines have orbited and landed on Venus and Mars; explored the Sun's environment; observed comets, and made close-range surveys while flying past Mercury, Jupiter, Saturn, Uranus and Neptune. These travelers brought a quantum leap in our knowledge and understanding of the solar system. Through the electronic sight and other "senses" of our automated spacecraft, color and comp ...

... such pollutants as nitric acid and sulfuric acid, both dissolving easily in water. This results in acidic water droplets that can be carried by prevailing winds, returning to Earth as acid rain, snow, or fog. This effects the lakes by changing the pH balance. As the water pH approaches 6, crustaceans, insects, and plankton begin to disappear. When the pH is slightly above 5, major changes start to happen, less desirable species of mosses and plankton may begin to flourish, whereas others will lessen in numbers and die off. Below pH of 5, the water is to acidic for many fish, the bottom is covered with undecayed material, and the shores may be dominated by mosse ...

... Their means of survival can only be identified from their fossil remains, and some identifications are in dispute. They ranged in weight from 4 to 6 lb., in the case of the compsognathus, and up to 160,000 lb., in the case of the brachiosaurus. Most dinosaurs were large, weighing more than 1,100 lb., and few weighed less than 100 lb. Most were herbivores, but some saurischians were carnivorous. The majority were four- footed but some ornithischians and all carnivores walked on their hind legs. Always classified as reptiles, dinosaurs have traditionally been assumed to have been reptilian in their physiology, cold-blooded, and ectothermic. In recent years sev ...

... think of another topic that fit into e veryone's lives and had an effect on everyone. The hurricane year is broken up into two seasons. They are referred to as early season and late season. The early season starts June first and runs to September 10. The late season starts on September 10 and runs to the end of November. The date of September 10 is the midway point between the two seasons. This is the date that separates early season from late season. This leads me to what my research was about. I am writing about the differences between early season and late season hurricanes and how they effect the variable that were mentioned earlier in the paper. I feel ...

... of the original being (Lawren). Though this has been done with frogs it has not yet been accomplished with mammals (Lawren). Another way to make a clone, as they do in the cattle buisness, is to split the cells of a early multi-celled embryo which will form two new embryos (Lawren). For it to get started into practice it took more than fifty years of questioning and testing. The first successful cloning experiment involved a leopard frog. It took place in, 1952 with group of scientist from the Institute for Cancer Research in Philadelphia (Lawren). To clone the frog they used an embryonic frog cell nucleus(Margery). 1962, John Gurdon of Cambridge U ...

... a real threat to the lives of people and wild life.It is vital to all of us that we fully understand the complex relationship between the atmosphere and the earth. The earth is getting warmer. the changes are small, so far, but they are expected to grow and speed up. Within the next 50 to 100 years, the earth will continue to heat up hotter than it has been in the past million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will effect weather everywhere, plants and animals everywhere and people everywhere. Humans are warming the earth¹s atmosphe ...

... away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler eff ...

... specific information about the valve. One of the more common found in industry is a gate valve. A gate valve is typically operated in the wide-open, or completely shut position. This type of valve is used where flow rates are not restricted. Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the path of a process flow. This type of valve is most commonly used in the throttling service. Ball valves take their name from the ball-shaped, movable element in the center of the valve. The movable ball rotates to let flow pass through, and closes to stop it. Ball valves are not made for throttli ...
