the subject handled in this study is the determination of antioxidant activities of extracts obtained from the urginea maritima (l.) baker plant’s leaves and tubers. extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. the antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. moreover, the free radical scavenging ...

The Baker and Wurgler (2006) sentiment index purports to measure irrational investor sentiment, while the University of Michigan Consumer Sentiment Index is designed to largely reflect fundamentals. Removing this fundamental component from the Baker and Wurgler index creates an index of investor sentiment that may better capture irrational sentiment. This new index predicts returns better than ...

As a model to provide hands-on, elementary understanding of "vortex dynamics", we introduce piecewise linear non-invertible map called twisted baker map. We show that the set hyperbolic repelling periodic points with complex conjugate eigenvalues and without are simultaneously dense in phase space. also these two sets equidistribute respect normalized Lebesgue measure, spite non-uniformity thei...
