C. Small dark regions called sunspots. Sunspots are cooler regions on the photosphere. Since they are 1000--1500 K cooler than the rest of the photosphere, they do not emit as much light and appear darker. B. During a total solar eclipse, an exceptional situation occurs, and for a few fleeting seconds, an emission spectrum can be observed. This happens at the very beginning of totality and just after the last bit of photosphere has been covered by the Moon. (Picture 1) For a period of several to perhaps ten seconds the chromosphere is visible as a red arc. (Recall that the chromosphere is a very thin layer just above the photosphere.) Often prominences are seen jutting from the chromosphere. The deep red color of the chromosphere comes from very strong emission in the hydrogen-alpha line at 656 nm. Because the chromosphere is quite rare and hot (with a temperature of about 10,000 K) it shows an emission spectrum in the absence of any light from the much brighter photosphere. Of course, the advance of the Moon soon covers the chromosphere and then the much rarer corona becomes visible as a broad white halo. Within minutes totality reaches completion, the chromosphere reappears on the o pposite side of the Sun followed seconds later by the overwhelming brightness of the photosphere. (Picture 2) Because the chromosphere is so thin, it forms an ideal subject for spectral imaging. A diffraction grating inserted in the light path of a telescope separates the light according to wavelength (just as in your spectrometer). An attached camera will then record the chromosphere imaged in each of the component wavelengths in its emission spectrum. This is the flash spectrum, so-called because of its brief accessibility. B. Because the chromosphere is quite rare and hot (with a temperature of

MPH503, Infertility and Public Health, Mod 3 Case Assignment - Essay Example This paper will attempt to answer those questions in relation to the results of the Bragdon v Abbot case. According to Bragdon v Abbot there is a right to reproduce, similar to the right to breathe. The case is saying that reproduction is a major life function just like any other bodily function and a disability related to reproduction is as important as a disability related to asthma (Walker , 2010). Further, the Code of Federal Regulations according to Walker (2001) states that "any physiological disorder, or condition, cosmetic disfigurement, or anatomical loss affecting one or more of the following body systems: Neurological, musculoskeletal, special sense organs, respiratory (including speech organs), cardiovascular, reproductive, digestive, genital-urinary, hemi and lymphatic, skin, and endocrine." As is noted, reproductive is listed. There is a lot of disagreement at the moment as to whether or not infertility is a disability, in fact, it appears that all of the states supreme courts cannot seem to agree. However, in this particular case, it was determined to be a disability and unless another case comes along and determines the results of this one to be incorrect, it will be considered by insurance companies and employers to be so. Certainly insurance companies must respond by assuring that insurance cover infertility treatment. This writer does not believe this will last long. There will be another supreme court case to come along. It is not that this writer disagrees but certainly at the cost of such treatments insurance companies will either need to raise cost or find a way not to cover the treatment. It is thought that certainly most states will go for the attempt to get insurance companies to pay for infertility treatment, with the exception, possibly of self-insured cases. In some ways, mandating insurance to pay for infertility treatment
