    solution with time, which leads to decrease in the absorption intensity of the peak at 400 nm along with appearance of a new peak at 300 nm corresponding to the formation of 4-AP. The kinetics of the reduction was followed by monitoring the absorbance spectrum of the reaction mixture for 30 min (Fig.8b). The reduction reaction was completed in 10 min at room temperature with associated color change of the solution from bright yellow to…

    and X-rays in the spectrum). Lasers are used routinely to remove certain skin growths or even unwanted hair. They are also used widely in eye surgery and as a cauterizing tool in other surgery. Eye surgery utilizes eximer lasers at about 100 nm. Soft tissue surgery such as resurfacing procedures typically uses a 3 micron YAG laser or 10 micron CO2 laser. Thermography is a medical imaging technique using infrared light. This passive imaging technique senses the thermal emission from the body at…

  • Oceanography: An Introduction To The Marine Environment

    different types of creatures that live in the water light up: squid, eel, jellyfish, which can be seen to the right in figure one, and many various species of fish have the ability to do such. The ability, called bioluminescence, is defined as “ the emission of light from living organisms”, according to Merriam-Webster. More informally, it is considered the ability where a creature, which can live either on or off-land, can produce their own light. Some insects, such as glow worms, can make…

  • The Intuition Of Science

    Science is intuitive. The tallest hill can be the shortest mountain. It is through our intuition that we come to know that the big ones are mountains and the little ones are hills. In some ways, the same is true for science. Science encompasses everything ranging from chemistry to archaeology, microbiology to astronomy. There are so many different aspects to science that it is hard to boil down to one concrete and concise definition. Science is involved with the study of the natural world. This…

  • Stages Of Human Development

    While there have been many different scientific theories and hypotheses related to the exact age of when these changes will occur, and many different factors that may influence the onset, there does not exist a standard age across the spectrum of cultures or genders of initial age of puberty. According to Zastrow and Kirst-Ashman (2010), “Acting as a catalyst for all of these changes is an increase in the production of hormones. Hormones are chemical substances secreted by the endocrine…

    and Grant (2011) found that "the [DST] policy costs Indiana households an average of $3.29 per year in increased electricity bills, which aggregates to approximately $9 million over the entire state . . . [and] social costs of increased pollution emissions that range from $1.7 to $5.5 million per year (p.4). These findings do not justify the continued use of Daylight Savings Time, especially considering the various disadvantages associated with…

  • Loss Of Species Research Paper

    In this day and age it is not as commonly known as it should be that, as a species, humans are increasingly forcing other species out of their habitats and killing them off. This point is made very clear by an alarming statistic Hawken states: “At the present rate of extinction … we may lose 20 percent of all the species on the planet within the next twenty to forty years … The loss of evolutionary potential is being called the “death of birth.”” (Hawken, 29). “Because resource supplies are…

  • How Did Niels Henrick David Bohr's Planetary Model

    himself to fix some of his problems with his planetary model of the atom. One problem was that according to the physics of the time, Rutherford’s atoms should have an extremely short lifetime. He had thought about the problem and knew of the emission spectrum of hydrogen. Though he added one assumption towards the electrons. Bohr suggested that the electrons could only orbit the nucleus in specific orbits or shells with a fixed radius. The electrons could only be within a radius based on the…
