Direct determination of the fully differential cross section by the time-dependent wave function

This paper focused on showing that the fully differential cross section of ionization during a collision of a proton and an antiproton with a hydrogen atom is directly expressed by the time-dependent wave function. For the projectile, wave function corresponding to the specific scattering angle was converted by two-dimensional Fourier transform from the wave functions of corresponding to impact parameters. This wave function shows how the ejected electron probability density distribution varies with time. We are shown that the calculation of the fully differential cross section of ionization can be directly determined by the local value of the wave function without the need to calculate the spatial integral for calculating the transition amplitude. It has been shown that the direct determination of the fully differential cross section by this time-dependent wave function is in good agreement with the results of determined the traditional method is by the transition amplitude.Comment: 7 pages, 9 figures. arXiv admin note: text overlap with arXiv:2206.1187

Ethanolic Extract of Hedysarum Alpinum L Is Rich in Flavonoids and Shows Free Radical Scavenging and Psychological Modulation Activities

Hedysarum alpinum L (HA) is reported to be able to support the immune and nervous systems.  However, there is only a few reports about the pharmacological activity of this plant. In current study, we investigated the phytochemical and pharmacological properties of an extract of HA using in vitro and iv vivo models. An extract of the specimens preserved in 70% ethanol was filtered and vacuum dried. Established conventional methods were used for quantitative determination of total phenolic and flavonoids content. Phytochemical characterization showed gallic acid, rutin, and quercetin are rich in the ethanolic extract of HA. In addition, the extract showed free radical scavenging activity on hydroxyl and lipid radicals with IC50 6.72 and 7.73 mg/ml, respectively. Furthermore, in vivo studies were performed on rats with orally applying the HA extract and then assessed their psychological behaviors in elevated plus maze (EPM) and open-field tasks. The HA extract exhibited psychological modulation activity. Our study suggests the ethanolic extract of HA could be potential to be used in the products of mood soother

Antioxidant and Anticonvulsant Effects of Medicinal Herbs

This study examines the anticonvulsant profile of some medicinal plants (astragalus mongolicus, corydalis sibirica, scutellaria baicalensis and Chelidonium majus) and antioxidant effects of Astragalus mongolicus and Chelidonium majus. Astragalus mongolicus and Chelidonium majus extracts possessed a significant dose-dependent scavenging effect on hydroxyl and lipid radicals by an in vitro ESR technique. Astragalus mongolicus (150 and 300mg/kg) and Scutellaria baicalensis (150 and 300mg/kg) extracts had anticonvulsant activities in the Pentylenetetrazol (PTZ). Maximal Scutellaria baicalensis in a dose of 150 and 300mg/kg significantly shortened the latency period seizures in the maximal electroshock (MES). Corydalis sibirica (150mg/kg) and Chelidonium majus (150 and 300mg/kg) extracts didn't influence on latency period in the PTZ and MES models. All extracts improved losing memory by passive avoidance task (longterm memory) and significantly didn't influence on drinking punishment in the Vogel's test.
