define clinical differences in the acute phase response and serum acute phase
reactants between gout, pseudogout and crystal-induced arthritis in the
presence of non-articular infections (CAI). Patients and Methods: Eleven patients with definite gout, 12 patients with pseudogout and 5
patients with CIA were included in the study. Results: The erythrocyte sedimentation rate (ESR) was significantly
different between gout (68.2 ± 49.9 mm/Hr) and CIA (113.8 ± 37.2 mm/Hr) but not
between gout and pseudogout (83.9 ± 45.6 mm/Hr) or between pseudogout and CIA.
The C-reactive protein (CRP) was significantly increased between gout (10.1 ± 7.9
mg/dL) and pseudogout (18.9 ± 9.8 mg/dL), gout and CIA (36.5 ± 12.4 mg/dL) as
well as between pseudogout and CIA. The peripheral white cell count was
significantly different between gout (9.27 ± 3.7 k/μL) and CIA (16.5 ± 6.8 k/μL),
and between pseudogout (8.9 ± 3.2 k/μL) and CIA. Conclusions: Measurement of ESR and CRP are helpful in
crystal-induced arthritis. The CRP has more discriminating utility than the ESR
in distinguishing between gout, pseudogout and CIA. Peripheral wbc is most
useful for differentiating crystal-induced arthritis from CIA.
This paper presents an analysis of the effect of parasitic resistances on the performance of DC-DC Single Ended Pri- mary Inductor Converter (SEPIC) in photovoltaic maximum power point tracking (MPPT) applications. The energy storage elements incorporated in the SEPIC converter possess parasitic resistances. Although ideal components significantly simplifies model development, but neglecting the parasitic effects in models may sometimes lead to failure in predicting first scale stability and actual performance. Therefore, the effects of parasitics have been taken into consideration for improving the model accuracy, stability, robustness and dynamic performance analysis of the converter. Detail mathematical model of SEPIC converter including inductive parasitic has been developed. The performance of the converter in tracking MPP at different irradiance levels has been analyzed for variation in parasitic resistance. The converter efficiency has been found above 83% for insolation level of 600 W/m2 when the parasitic resistance in the energy storage element has been ignored. However, as the parasitic resistance of both of the inductor has increased to 1 ohm, a fraction of the power managed by the converter has dissipated; as a result the efficiency of the converter has reduced to 78% for the same insolation profile. Although the increasing value of the parasitic has assisted the converter to converge quickly to reach the maximum power point. Furthermore it has also been observed that the peak to peak load current ripple is reduced. The obtained simulation results have validated the competent of the MPPT converter model.
