Gunpowder is a compound mixture of sulphur‚ charcoal‚ and potassium nitrate (saltpetre). The sulphur and charcoal act as fuels‚ while the saltpetre works as an oxidizer. Gunpowder was first discovered in China during the 9th century‚ by Chinese alchemists in search for an elixir to provide immortality. It was initially the

Abstract: Definitions and classifications used in the study of air pollution are introduced. lsointroduced are a brief history of air pollution‚ its regulation‚ and trends of its ambient concentrations and emissions. Keywords: Anthropogenic‚ biogenic‚ geogenic emissions biogenic‚; primary and secondary pollutants; criteria‚ hazardous‚ radioactive‚ indoor pollutants; sulfur smog‚ photochemical smog; UN-ECE‚ US-EPA‚ Clean Air Act. Air pollution spreads easily as it travels into the atmosphere.

Discussion Field observations and lab analysis indicated that‚ there are many types of damages that wall painting can undergo in the Komir temple. All building and decoration materials of Komir temple have been investigated concerning the contamination with soluble salts. Soluble salts represent one of the most important causes of stone decay that may precipitate on the external surface (“efflorescence’s”) or in proximity of the surface (“subefflorescence’s”) [Brai et al 2010]. The degradation induced

Before I go on about the use of fertilizers in organic farming‚ you must first understand what organic farming is. The simplest way to describe organic agriculture is agricultural production without the use of synthetic chemicals (fertilizers‚ pesticides‚ antibiotics‚ etc). For crop production‚ organic materials such as compost and manure are used to maintain soil organic matter and as sources of nutrients. Nitrogen-fixing as well as pest resistant plant varieties are utilized. The incorporation
