Possible definitions for qfever
fever
Abnormally high body temperature or a disease characterized by it. It most often occurs with infection. Normal core body temperature, measured orally, does not exceed 99\u00b0 F (37.2\u00b0 C). Up to 105\u00b0 F (40.6\u00b0 C), fever causes weakness and is best treated with aspirin, acetaminophen, or other antipyretic drugs. At 108\u00b0 F (42.2\u00b0 C) or more, it can lead to convulsions and death. In treatment, it is important to know the underlying cause. Fever appears to be a defense against infectious disease, stimulating leukocytes and increasing antibody production and perhaps killing or inhibiting bacteria and viruses that live within a narrow temperature range.
lever
Simple machine used to amplify physical force. All early people used the lever in some form, for moving heavy stones or as digging sticks for land cultivation. Balance beams for weighing were probably used in Egypt c.5000 BC; they consist of a bar pivoted at its center with weights on one end balancing the object on the other. As early as 1500 BC people were raising water and lifting soldiers over battlements using the swape or shadoof, a long lever pivoted near one end with a platform or container hanging from the short arm and counterweights attached to the long arm.
