[5.4]. When heat is transferred from the surroundings to the system, q has a positive value. Likewise, when work is done on the system by the surroundings, w has a positive value (Figure 5.6). In other words, both the heat added to the system and the work done on the system increase its internal energy.onversely, both the heat lost by the system to the surroundings and the work done by the system on the surroundings have negative values; that is, they lower the internal energy of the system. The relationship between the signs of q and w and the sign of E is presented in Table 5.1.
In the same study, 38.5% of patients with noninflammatory âsoft tissue rheumatismâ had a positive ANA result. at a 1:40 dilution, and 23.1% at a 1:80 dilution. Slater et al (6) studied 1,010 consecutive ANA results at a teaching hospital and attempted to correlate the results with clinical histories by chart review. Fifteen percent of all patients and 30% of patients older than 65 years had a positive ANA titer of 1:40 or greater, but the positive predictive value for rheumatic disease was low. The false-positive rate for any rheumatic disease was 72% in patients 65 years old or younger, and 90% in. patients older than 65 years.
