Primary B symptoms include the following, and in order to be considered B symptoms, they generally must persist for at least six months: Unexplained low-grade fevers. Drenching lymphoma night sweats.
Propane: Liquefied Petroleum Gas (LPG). Propane, or liquefied petroleum gas (LPG), is a clean-burning fossil fuel that can be used to power internal combustion engines. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO 2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance, and most LPG used in U.S. comes from domestic sources. The availability of LPG-fueled light-duty passenger vehicles is currently limited.
Indane is available in compact 5 kg cylinders for rural, hilly and inaccessible areas, 14.2 kg cylinders for domestic use, and 19 kg and 47.5 kg for commercial and industrial use. LPG is a blend of Butane and Propane readily liquefied under moderate pressure. LPG vapour is heavier than air; thus it normally settles down in low-lying places. Since LPG has only a faint scent, a mercaptan odorant is added to help in its detection.
