The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare. Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.

Factories in China often produce what type of gas in their emissions that acts as pollution?, Context: A dense wave of smog began in the Central and Eastern part of China on 2 December 2013 across a distance of around 1,200 kilometres (750 mi), including Tianjin, Hebei, Shandong, Jiangsu, Anhui, Shanghai and Zhejiang. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. The heavy smog heavily polluted central and southern Jiangsu Province, especially in and around Nanjing, with its AQI pollution Index at "severely polluted" for five straight days and "heavily polluted" for nine. On 3 December 2013, levels of PM2.5 particulate matter average over 943 micrograms per cubic metre, falling to over 338 micrograms per cubic metre on 4 December 2013. Between 3:00 pm, 3 December and 2:00pm, 4 December local time, several expressways from Nanjing to other Jiangsu cities were closed, stranding dozens of passenger buses in Zhongyangmen bus station. From 5 to 6 December, Nanjing issued a red alert for air pollution and closed down all kindergarten through middle schools. Children's Hospital outpatient services increased by 33 percent; general incidence of bronchitis, pneumonia, upper respiratory tract infections significantly increased. The smog dissipated 12 December. Officials blamed the dense pollution on lack of wind, automobile exhaust emissions under low air pressure, and coal-powered district heating system in North China region. Prevailing winds blew low-hanging air masses of factory emissions (mostly SO2) towards China's east coast.

How does the word evangelical differ from english in german?, Context: During the Reformation, the term was hardly used outside of the German politics. The word evangelical (German: evangelisch), which refers to the gospel, was much more widely used for those involved in the religious movement. Nowadays, this word is still preferred among some of the historical Protestant denominations, above all the ones in the German-speaking area such as the EKD. The German word evangelisch means Protestant, and is different from the German evangelikal, which refers to churches shaped by Evangelicalism. The English word evangelical usually refers to Evangelical Protestant churches, and therefore not to Protestantism as a whole. It traces its roots back to the Puritans in England, where Evangelicalism originated, and then was brought to the United States. The word reformatorisch is used as an alternative for evangelisch in German, and is different from English reformed (German: reformiert), which refers to churches shaped by ideas of John Calvin, Huldrych Zwingli and other Reformed theologians.
