Black Wallpaper Border Biography
The Great Plains Black History Museum is located at 2213 Lake Street in the Near North Side neighborhood in North Omaha, Nebraska. It is housed in the Webster Telephone Exchange Building, which is listed on the National Register of Historic Places. A nationally renowned institution for more than 30 years, the museum includes more than 100,000 periodicals, manuscripts, photographs and research materials.[1]
It is the largest museum devoted to the black experience on the Great Plains.[2] The facility has been closed because of needed renovation but, as the new president says, "The museum is open." As of the spring of 2011, a new board was in place which was holding community meetings to broaden discussions of the museum's future.A black light, also referred to as a UV light, ultraviolet light, or Wood's lamp, is a lamp that emits ultraviolet radiation (UV) in the long-wave (near ultraviolet, UVA) range, and little visible light. Other types of ultraviolet lamp emit large amounts of visible light along with the ultraviolet; however, a "black light" usually refers to a lamp that has a dark blue optical filtering material in the glass envelope of the bulb (or the lamp housing) which blocks most of the visible light, so the lamp emits mostly ultraviolet. Ultraviolet radiation is invisible, but a small fraction of visible light passes through the filtering material, with wavelengths no longer than 400-410 nm, and as a result, when operating the lamp it emits a dim purple or violet glow. Wood's glass is one type of filtering material which is used in black lights.Damasks used one of the five basic weaving techniques of the Byzantine and Islamic weaving centres of the early Middle Ages,[3] and derive their name from the city of Damascus, which at the time was a large city active in both trading, as part of the silk road, [4] and manufacture. Damasks were scarce after the ninth century outside of Islamic Spain, but were revived in some places in the thirteenth century.[5] The word "damask" is first seen in a Western European language in the mid-14th century in French.[6] By the fourteenth century, damasks were being woven on draw looms in Italy. From the fourteenth to the sixteenth century, most damasks were woven in a single colour, with a glossy warp-faced satin pattern against a duller ground. Two-colour damasks had contrasting colour warps and wefts, and polychrome damasks added gold and other metallic threads or additional colours as supplemental brocading wefts. Medieval damasks were usually woven in silk, but wool and linen damasks were also woven.
