Analysis to Declaration of independance essays
Analysis to Declaration of independance essays In response to the questions to consider, Spain had many positive opportunities come about from the voyage of Christopher Columbus. One major thing was the fact that they now could brag about their discovery of America for all time, as we know it. Even today they think that America is the way it is because of them. (I spent 2 long years there) But more realistically, they gained territory for their church. One of the first things done in the New World was work of conversion to the heathens to Christianity. Columbus, although being Portuguese, gave all of the countries a Spanish name to pay respect to the country that made his voyage possible. The major plans of Columbus for this new found and mysterious breed was of course to convert the people to their " holy faith " as he puts it. One of the first things that the Indians did when they saw Columbus was bow down to him and give him drinks, food and other gifts. Their reasoning for doing such was because they thought Columbus was the "Man from Heaven ". Little did they know he was a mere explorer and trespasser that would bring them bad fortune and many diseases along with power-hungry Anglo-Saxon Englishmen. However, the Europeans set forth the groundwork for a more productive people that would help the world advance immensely in the years to come. Columbus also talks of the geographical location and climate. One remark where he refers to the power of the sun in this area demonstrates that where he comes from is not quite as hot and was quite a change for he and his crew. ...

How Crime Scene Insects Reveal the Time of Death
How Crime Scene Insects Reveal the Time of Death When a suspicious death occurs, a forensic entomologist may be called to assist in processing the crime scene. Insects found on or near the body may reveal important clues about the crime, including the victims time of death. Insects colonize cadavers in a predictable sequence, also known as insect succession. The first to arrive are the necrophagous species, drawn by the strong scent of decomposition. Blow flies can invade a corpse within minutes of death, and flesh flies follow close behind. Soon after coming, the dermestid beetles, the same beetles used by taxidermists to clean skulls of their flesh. More flies gather, including house flies. Predatory and parasitic insects arrive to feed on the maggots and beetle larvae. Eventually, as the corpse dries, hide beetles and clothes moths find the remains. Forensic entomologists collect samples of crime scene insects, making sure to take representatives of every species at their latest stage of development. Because arthropod development is linked directly to temperature, she also gathers daily temperature data from the nearest available weather station. In the lab, the scientist identifies each insect to species and determines their exact developmental stage. Since the identification of maggots can be difficult, the entomologist usually raises some of the maggots to adulthood to confirm their species. Blow flies and flesh flies are the most useful crime scene insects for determining the postmortem interval or time of death. Through laboratory studies, scientists have established the developmental rates of necrophagous species, based on constant temperatures in a laboratory environment. These databases relate a species life stage to its age when developing at a constant temperature, and provide the entomologist with a measurement called accumulated degree days, or ADD. ADD represents physiological time. Using the known ADD, she can then calculate the likely age of a specimen from the corpse, adjusting for the temperatures and other environmental conditions at the crime scene. Working backward through physiological time, the forensic entomologist can provide investigators with a specific time period when the body was first colonized by necrophagous insects. Since these insects almost always find the corpse within minutes or hours of the persons death, this calculation reveals the postmortem interval with good accuracy.
