Antioxidant activity of exo-metabolites produced by Fusarium oxysporum: An endophytic fungus isolated from leaves of Otoba gracilipes. [PDF]
Microbiologyopen, 2019 An endophytic fungus isolated from the leaves of Otoba gracilipes, a poorly explored medicinal plant from tropical rainforest in Colombia, was cultivated, and its extracellular crude extract was evaluated for antioxidant activity. Using traditional and molecular methods of characterization (ITS1, NL1 regions), the endophyte was identified as Fusarium ...

Journal of Sociolinguistics, Volume 27, Issue 2, Page 115-135, April 2023., 2023 Abstract This article analyses the role of linguistic skills in the process of defining professional classifications in Spain during 1919–1980. The aim is to determine the social evaluation of the skills involved. To retrace the classifications, a total of 114 official documents were examined, establishing a chronological division into three major ...

Energy Spectrum of Shallow Donor in Elongated InAs/GaAs Volcano‐Shaped Quantum Dot
Advances in Condensed Matter Physics, Volume 2018, Issue 1, 2018., 2018 We study the effect of the nonparabolicity of the conduction band on the spectral properties of the shallow donor in elongated InAs/GaAs quantum dots with volcano‐shaped profile in the framework of the Kane model by using a simple semiempiric relation between geometrical parameters of the quantum dot profile and the confinement potential, governing the
