In one sentence, describe what the following article is about: You will need two lights, a long tube light with UVA and UVB and a basking light. The first light will be full spectrum and provide your pet with UVA and UVB rays. This bulb will span most of the tank, but make sure to leave enough room on the other end for a basking light. On one end, install a bulb for basking. Your bearded dragon needs light for 12 to 14 hours a day. Bearded dragons must have a good source of UVB light in order to metabolize calcium and reduce the risk of having weak bones as a result of metabolic bone disease (MBD). You can either choose a separate UVB light and heat source, or a combined array. The latter are more expensive, but great in a confined space. Most commercial vivariums come set up to take a separate UVB fluorescent tube, plus a heat source. UVB bulbs range from 5% 12%, with the more powerful bulbs providing more UVB, which is preferable for adult dragons. The 5% bulbs are appropriate for juveniles. Make sure the dragon spends most of his time within a 12 inch range of the UV tube, since there is a significant drop off in penetration after this distance, and the dragon receives limited benefit. Also, the UVB emission degrades after about six months of use, so either change the bulbs every six months, or take the bulb to a reptile specialist center with a device capable of reading the UVB output to make sure the lamp is still effective. The vivarium should have two heat sources: a basking spot heat lamp that provides the vivarium's general heat along with the hot spot to bask in, plus a low-level heater to provide heat at the cool end or at night in places where the ambient temperature drops below 75 F (23.9 C). The heat lamp should be mounted at one end of the vivarium, out of reach of the dragon, and provide a basking spot temperature of around 95 F (35 C). The ambient heat should be placed at the cool end and only needs to have moderate heat output sufficient to prevent the cool end falling below 85 F (29.4 C). This heat could either be a wall mounted heat pad or a black ceramic light. To mount the lights, you can purchase lamp fittings or brackets from a pet store or an online store. To monitor the temperatures and the gradient in the vivarium, you need two thermometers, one at either end. The most basic thermometers are simple circular dials that point to the temperature. For an optimum environment, it helps to put both the heat lamp and the auxiliary heater on separate thermostats (set to 95 F or 35 C at the warm end and 75 F or 23.9 C at the cool end) so the heaters automatically click on and off to maintain a steady environmental temperature. To install the thermometer, you can purchase fittings or brackets from a pet store or an online store. The vivarium needs to have low humidity because bearded dragons are from low humidity climates. Make sure there is a screen somewhere that allows airflow, and that will help keep the humidity from getting too high. To install the humidity gauge, you can purchase fittings or brackets from a pet store or an online store. Follow the included instructions for installation.
Summary: Install two bulbs. Choose the appropriate bulb. Install two heat sources. Place two thermometers. Install a humidity gauge.

In one sentence, describe what the following article is about: There are different types of rosin, but the two most common are light rosin and dark rosin. Light rosin is harder, and not quite so sticky as dark rosin. It's sometimes called amber or summer rosin (for the time of year it's tapped), and it's appropriate for the higher strings, like violins and violas. Dark rosins, or winter rosins, tend to be very sticky. The stickier the rosin is, the fuller the sound will be. Select a dark rosin if you play a low-stringed, large instrument like the cello, for which a fuller sound is preferred. Boxed rosin, as its name suggests, comes in a box, which makes it less prone to cracking and breaking. It's typically only available as a light or summer rosin and is usually a lower quality than cake rosin. But its low price tag makes it a good option for beginners. While cake rosin tends to be more expensive than boxed rosin, you're getting a purer, more high-quality rosin. It comes in a variety of colors, from amber to black, so you can select the best kind for your instrument. New rosin needs to be roughened in order for it to stick to your bow. Take a piece of sandpaper, around 220-grit, and rub it all over the top of the rosin block. Stop when you see the rosin producing dust. You can also use a knife to score it and cut a crosshatch pattern into the top.
Summary: Buy light rosin for smaller instruments. Choose dark rosin for a fuller sound for larger instruments. Select boxed rosin for a durable, low-priced option. Opt for cake rosin for a higher-quality product. Rub new rosin with fine-grit sandpaper to increase stickiness.

In one sentence, describe what the following article is about: Some librarian positions in public libraries require only an associate's or bachelor's degree. These types of positions are often for teen and children's librarians. Almost all intermediate and advanced level library jobs require a Master's in Library Science (MLIS). These professional librarians have more advanced duties, such as overseeing the assistants or updating the library's collections. Librarians fill many roles, including reference librarian, corporate librarian, cataloguer, library manager, collections manager (deciding which books are added and removed), children's librarian, teen librarian, school librarian (K-12), academic librarian, systems librarian (involves IT work), or running the circulation desk. Research the roles that sound interesting to you, and focus your education towards these positions. Many library science programs also offer a specialization in archives. Archivists handle historic texts, preserving them physically and granting access to them for research. Many academic librarians also hold an additional master's degree in a specific subject. If you're passionate about an academic subject, such as art, law, music, business, or psychology, this path can combine it with your interest in libraries. Special libraries are usually private, company libraries that hold collections centered on legal, business, medical, or government resources. Most librarian positions in special libraries require a minimum of a master's degree in library science. A librarian may also need to have degrees or experience in the special library's specific subject area. Examples of subjects include law, business, science, and government.
Summary:
Look for jobs that require a college degree. Study for a Master's in Library Science. Specialize. Train for an academic library. Consider working in a special library.
