Spanish holm oak (Quercus ilex subsp. ballota) open woodlands (dehesas) maintain a high diversity of plants and animals compared to other forested Mediterranean habits, but little is known about the responses of epiphytic lichens to different management regimes that are applied to this woodland type. The present study was carried out in central-southern Spain and included four management regime...

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...

Abstract Introduction Increased slow-wave activity (SWA) following sleep loss is a well-established physiological marker of increased pressure. Recent research found SWA changes in response to partially accounted for next-day decrements positive affect (Finan et al., 2015; 2017). To our knowledge, however, this line inquiry has been limited adults. Recently, we greater during night healthy pred...

We present an extension, for nonlinear optimization under linear constraints, of an algorithm for quadratic programming using a trust region idea introduced by Ye and Tse [Math. Programming, 44 (1989), pp. 157–179] and extended by Bonnans and Bouhtou [RAIRO Rech. Opér., 29 (1995), pp. 195–217]. Due to the nonlinearity of the cost, we use a linesearch in order to reduce the step if necessary. We...

two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of salvia sharifii. the compounds were purified using several chromatographicmethods. structural elucidation of the compounds was performed using their 1h and 13c-nmrdata, ei mass and uv spectral data. the co...
