This work introduces an efficient procedure for measuring reactive power in single-phase systems in the presence of harmonic distortion. The measurement of reactive power is based on the application of the ADALINE network to estimate the voltage harmonics and, subsequently, to define a certain single-phase magnitude whose average value provides the reactive measurement. Two definitions of the reactive power have been considered: the reactive power of the fundamental harmonic Q1 and the well-known Budeanu reactive power QB, which is physically meaningless according to many studies. In addition, the proposed neural procedure of calculating the two reactive powers has been compared with other traditional methodologies for calculating Q, specifically, the application of FFT to voltage and current and the 90° voltage delay method. The new methodology has been applied to two laboratory case s...

The objective of this study was to determine the association between serum uric acid (UA) and risk factors associated with metabolic syndrome (MS) in a high altitude population. We included 174 adults, natives from Junin city, 4107 msnm (75 men and 99 women). The prevalence of risk factors like as obesity, hypertension, hyperglycemia, hypertriglyceridemia and low serum level of HDL-cholesterol and uric acid serum level, were estimated. Subjects were stratified by gender into quartiles of serum uric acid levels. A higher prevalence of hyperuricemia in men than in women was found. It is observed that the prevalence of metabolic syndrome (MS) increases in both men and women according to quartile of serum uric acid (UA). A significant association between uric acid level and triglyceride level in both men and women was found. It is concluded that the estimated values would show the prevalence...
