On well p-embedded subgroups of finite groups

Let G be a finite group, H a subgroup of G and HsG the subgroup of H genarated by all those subgroups of H which are s-permutable in G. Then we say that H is well p-embedded in G if G has a quasinormal subgroup T such that HT=G and T∩H≤HsG. In the present article we use the well p-embedded groups to obtain new characterizations for some class of finite soluble, supersoluble, metanilpotent and dispersive groups

AMARANTHUS AS A SOURCE OF POLYPHENOLIC COMPOUNDS AND FLAVONOIDS FOR USE IN MEDICINE

Amaranth is used as a medicinal plant with antioxidant, hemostatic, and wound-healing properties. The aim of the research is the quantitative determination of polyphenolic compounds and flavonoids in ethanolic extracts of amaranth seeds of the "Lera" and "Ultra" varieties and leaves Amaranthus retroflexus. Methods. Extracts were obtained by infusion for 7 days in 70% and 80% ethanol. Quantitative determination of secondary metabolites was conducted by spectrophotometric methods. Results. The largest amount of polyphenolic compounds was found in the ethanolic extract of Amaranthus retroflexus leaves - 0.228 mg/ml. More polyphenols were found in the ethanolic extract of amaranth seeds of the "Lera" variety than in the extract of amaranth seeds of the "Ultra" variety. In the extract of leaves of Amaranthus retroflexus, 2.1 x 10-4 mg/ml of flavonoids were found, in extracts of amaranth seeds were found from 0.7 x 10-5 mg/ml to 1.55 x 10-5 mg/ml of flavonoids. Conclusion. The ethanolic extract of the leaves of Amaranthus retroflexus contains a greater number of investigated secondary metabolites than the extracts of amaranth seeds of the "Lera" and "Ultra" varieties. The ethanol extract of amaranth seeds of the "Lera" variety contains more polyphenolic compounds and flavonoids than the ethanol extract of amaranth seeds of the "Ultra" variety

Magnetic Levitation

The idea of defying gravity always seemed to go against the laws of physics. However, with the assistance of magnets, this can be doable. Static magnetic levitation is not possible, but once the magnets are put into motion, they can induce a magnetic field. Experiments were performed to determine the best materials to achieve magnetic levitation. Neodymium magnets, a copper sheet, and motors were three of the most pivotal supplies. The positioning of these materials was also examined. Magnetic levitation is an applicable innovation. Many forms of transportation are looking into using the idea to improve efficiency. Different matters of physics were analyzed in order to comprehend the concept of magnetic levitation
