A Withanolide-rich Fraction of Athenaea velutina Induces Apoptosis and Cell Cycle Arrest in Melanoma B16F10 Cells
(2021-01-01)
Athenaea velutina is a promising Brazilian shrub with cytotoxic and antimigratory properties against cancer cells. However, the mechanism of induction of cancer cell death and the compounds involved remain unknown. To ...
Analysis of a series resonant AC/DC converter with integral cycle mode control for high frequency AC distribution systems
(World Scientific and Engineering Academy and Society, 2020-02)
The study of a resonant AC/DC converter, thought for high frequency sinusoidal AC power distribution systems, is performed in this article. The control switch is commuted at the resonant current zero crossings, staying ...
Geomagnetic storm occurrence and their relation with solar cycle phases
(Amer Geophysical Union, 2021)
Using a time series of geomagnetic storm events between 1957 and 2019, obtained by selecting storms where Dst<-50 nT, we have analyzed the probability of occurrence of moderate, intense, and severe events. Considering that ...
Are there Goodwin employment-distribution cycles? theoretical and empirical evidence
(Facultad de Ciencias Ecónomicas, 2008)
El modelo predador-presa de Goodwin predice ciclos en el espacio empleodistribución. Después de las controversias del capital de Cambridge, este modelo en particular no puede ser visto como teóricamente consistente. No ...
