1. Seismic response of aboveground steel storage tanks: comparative study of analyses by six and three correlated earthquake components
Ground motions at a point on the ground surface can be decomposed to six components, namely three translational components and three rotational components; translational components include two components in the horizontal plane, and one in the vertical direction. Rotation about horizontal axes leads to rising of rocking, while the rotational component about

2. Rapid validated HPTLC method for estimation of piperine and piperlongumine in root of Piper longum extract and its commercial formulation
Piperine and piperlongumine, alkaloids having diverse biological activities, commonly occur in roots of Piper longum L., Piperaceae, which have high commercial, economical and medicinal value. In present study, rapid, validated HPTLC method has been established for the determination of piperine and piperlongumine in methanolic root extract and its commercial

4. Voltage unbalace numerical evaluation and minimization:estimation by incremental sensitivity analysis and analytical solutions / Avaliação e minimização numérica do desequilíbrio de tensão : estimativa por análise de sensibilidade incremental e soluções analíticas
Voltage unbalance is one of the parameters analysed in power quality studies, representing the difference between the magnitudes of the voltages of a tri-phase electrical system, and the phase shift between these. It is desirable to have sinusoidal voltages with identical magnitudes and 120 electrical degrees phase shift between them, but in practice, there

5. Calcium-activated potassium channels in goldfish hair cells.
1. Characteristics of Ca(2+)-activated K+ channels in the basolateral membrane of hair cells isolated from the caudal part of the goldfish saccular macula were studied mainly with the inside-out mode of the patch clamp method. 2. Several types of Ca(2+)-activated K+ channels differing in unitary conductance were identified. The conductances (n = 156) ranged
