Techncian welds with an oxyacetylene torch

Welding. Technician in protective clothing welds a section of an oil and gas pipeline with an oxyacetylene torch. Welding involves heating two pieces of metal so that they melt and fuse together. Oxyacetylene torches use a mixture of oxygen and acetylene to create the heat needed to melt the metal. The acetylene burns in oxygen to form carbon monoxide; this reaction provides most of the heat. The carbon monoxide then reacts with atmospheric oxygen to give the blue flame. The flame from an oxyacetylene torch is "neutral", meaning that it burns without leaving oxides in the cut region. Photographed during work on the Urengol-Ushgorod pipeline in Russia

Fairy ring fungus Featured 8 Aug 2003 Print

Fairy ring fungus

Fairy ring fungus (Marasmius oreades) in a grassy field. This fungus produces a characteristic ring of brown, rounded mushrooms after heavy rainfall in summer and autumn. These hold the spores ready for dispersal. For the rest of the year the fungus is concealed underground in its mycelium form. It may produce the same ring for many years (some are known to be over 150 years old). The mushrooms are edible and tasty, but other toxic fungi also produces rings, so care is needed. M. oreades is native to Europe and North America
