31. As recently as 1977, an offshore eruption sent a 1,000-metre column of burning methane gas into the air.

32. Sulphate reducing bacteria were never detected, and methane excretion was not affected by sulphate feeding.

33. As with domestic refuse, the problems of methane gas generation also exist when disposing of industrial waste underground.

34. At those temperatures and pressures,[www.Sentencedict.com] methane combines with water into a solid form called a gas hydrate.

35. They remove dead timber, they are wonderful architects, and they generate methane gas, which contributes to the greenhouse effect.

36. The methane gas produced is used for heating and generating power for the farm buildings.

37. Of course, a basic corollary of the theory is that deep drilling should uncover a portion of these massive methane resources.

38. The blast, 610m below ground, is thought to have been caused by a mix of coal dust and methane gas.

39. Even argon may condense on Uranus and Neptune to form a thin haze above the methane cloud layer.

40. This may explain the absence of methane in the breath of 40-50% of western populations.

41. To make methane[sentencedict.com], burn one weight of hydrogen with three of carbon.

42. A section on cooking should not be left without a consideration of the potential of the methane digester.

43. Methane condenses to form a cloud layer above the ammonia clouds, leaving a gas that is almost entirely hydrogen and helium.

44. Producing methane gas from landfill sites, sewage works and organic wastes is another extremely practical use of resources.

45. Methane gas from rubbish tips is another potentially valuable source of energy.

46. Titan is unique in having a thick atmosphere made mostly of nitrogen, with some methane and possibly argon.

47. Methane is a potent greenhouse gas, each molecule trapping 25 times as much heat radiation as one molecule of carbon dioxide.

48. But it might contribute to global warming because methane is a powerful greenhouse gas.

49. Methane formation continues in anthracite rank stages as shown in Fig. 1.

50. As a member of the Stella Coal Company rescue team, he used Stephenson's lamp as a methane detector.

51. For matrix materials like methane, nitrogen, krypton and xenon, this is not too surprising.

52. The natural decomposition process which occurs in landfills also produces large quantities of methane and thereby presents a significant explosion hazard.

53. The pillars of coal left behind were compressed, releasing large amounts of an explosive mixture of air and methane called firedamp.

54. Four others are hooked into systems to control the release of methane gas.

55. In recent studies, however, we have shown that methane production is more important than previously believed.

56. Zubrin proposes burning methane with liquid oxygen for the return trip to Earth.

57. The Methane produced on landfill sites is very explosive and can lead to severe illness if inhaled to a great extent.

58. These research activities have led to the initial isolation of many of the now known species of methane producing bacteria.

59. Experts believe the absence of water in the toilet allowed a lethal build-up of methane gas.

60. The reasons why western populations separate into methane producers and non-producers has never been explained.
