Some plans are likely to offer coverage that is even more comprehensive than Medicare's standard drug coverage. The first enrollment period starts on Nov. 15, 2005, and runs through May 15, 2006. For those who don't join a Medicare prescription drug plan by May 15, 2006, the monthly premium rises 1 percent a month.
Phase-contrast anddarkfield microscopies are used for wet mounts, whereas brightfield can be used for both wetmounts and stained specimens.You will also get your first exposure to the preparation of a bacterial smear and subsequent staining ofit. However, you are making a simple stain, using only one dye. Go DOWN into the algae and muck to get a really good sample of protozoa and algae. ï· Focus on the sample using 10X, then go to 40X (NOT 100X). Start with brightfield, thenswitch over to darkfield and phase-contrast (see directions below).
What is a wet mount? In a wet mount, the specimen is suspended in a drop of liquid (usually water) located between slide and cover glass. The water refractive index of the water improves the image quality and also supports the specimen. In contrast to permanently mounted slides, wet mounts can not be stored over extended time periods, as the water evaporates. For this reason, a wet mount is sometimes also referred to as a âtemporary mountâ to contrast it from the âpermanent mountsâ, which can be stored over longer times. The permanently mounted slides use a solidifying mounting medium, which holds the cover glass in place.
