Unreferenced date December 2009 The Association of Religion Data Archives ARDA is a free source of online information related to American and international religion . Founded as the American Religion Data Archive in 1997, and online since 1998, the archive was initially targeted at researchers interested in American religion. One of the primary goals of the archive is to democratize access to quality information on religion by making this information as widely accessible as possible. The targeted audience and the data collection have both greatly expanded since 1998. Over 450 surveys, membership reports, and other data collections are currently available for online preview, and most can be downloaded free of charge. In February 2006, the American Religion Data Archive became the Association of Religion Data Archives when an international data archive was added. The archive now includes both American and international collections as well as features for educators, journalists, religious congregations, and researchers. Features include national profiles, GIS maps, church membership overviews, denominational heritage trees, tables, charts, and other summary reports. The archive, visited by tens of thousands of people each month, is a rich source of information related to religion in the United States. Data included in the ARDA are submitted by the foremost religion scholars and research centers in the world.

Infrared lamps are electrical devices which emit infrared radiation. Infrared lamps have many uses, but are most commonly used in communication and heating . Less common uses include illumination for use with night vision device s. Heating main Infrared heater Radiant heating Infrared heating uses infrared lamps, commonly called heat lamps to transmit infrared radiation to the body that is being heated. When large bodies or bodies with a large surface area need to be heated, infrared lamps are often used in banks. Infrared heat lamps are commonly incandescent bulbs which are able to produce infrared radiation.

These scanners make two passes over the film once for RGB and once for infrared. This is slower than the Nikon or Minolta approach, since two passes ... quality. Applicability The three color dyes in modern color film emulsions respond equally to infrared light, so the infrared image looks relatively opaque compared to the RGB image. Any dust spots or scratches appear as dark spots in infrared, making it easy to find and correct for these dust spots. Kodachrome film dyes are more sensitive to infrared than Ektachrome film dyes, making it more ... s ref http www.silverfast.com highlights isrd en.html ref , claim to use infrared cleaning to find dust spots even when scanning Kodachrome.
