Ethnopharmacology, phytochemistry and biological activity of Erodium species: a review

2019

Erodium spp. is a genus that can be found in all continents that has been traditionally used in folk medicine to treat many diseases such as hemorrhage, dermatological disorders, indigestion, and inflammatory diseases. Moreover, Erodium leaves have been used for the preparation of salads, omelets, sandwiches, sauces and soups, among other food products. The objective of this review was to show the recent and relevant studies about extraction of bioactive compounds, the phytochemical characterization, the potential biological activities and toxicological evidence reported in both in vitro and in vivo studies from Erodium spp. In addition, the use of Erodium spp. as natural compounds against …

Typification of the name Erodium soluntinum Tod. (Geraniaceae) and its taxonomic implications

2017

The present contribution is part of the ongoing work promoted by the Italian Botanical Society aimed at recognizing and typifying all the taxa described from Italy and their loci classici, in order to increase their systematic knowledge and promote further studies (Domina et al. 2012, Peruzzi et al. 2015, Brundu et al. 2017). One of these taxa is Erodium soluntinum Todaro (1869: 36), a species belonging to Geraniaceae and considered an Italian endemic (Conti et al. 2005, Peruzzi et al. 2014, 2015). This name, as far as we are aware, is not yet typified.

Biante e la Sardegna. Libertà dominio e felicità in Erodoto

1999

A partire da un celebre episodio riportato da Erodoto nella sua narrazione della rivolta ionica al debutto del V secolo, si ricostruiscono le tappe dello sviluppo del concetto felicità nel pensiero politico greco fino al IV secolo, mostrandone tutta l’ambiguità che ne deriva dal legame inscindibile con le idee di dominio e di libertà.

Know your full potential: Quantitative Kelvin probe force microscopy on nanoscale electrical devices

2018

In this study we investigate the influence of the operation method in Kelvin probe force microscopy (KPFM) on the measured potential distribution. KPFM is widely used to map the nanoscale potential distribution in operating devices, e.g., in thin film transistors or on cross sections of functional solar cells. Quantitative surface potential measurements are crucial for understanding the operation principles of functional nanostructures in these electronic devices. Nevertheless, KPFM is prone to certain imaging artifacts, such as crosstalk from topography or stray electric fields. Here, we compare different amplitude modulation (AM) and frequency modulation (FM) KPFM methods on a reference s…

Hastifolins A-G, antefeedant neo-clerodane diterpenoids from Scutellaria hastifolia

2010

From the aerial parts of Scutellaria hastifolia, family Lamiaceae (Labiatae), seven neo-clerodane diterpenoids (hastifolins A-G) were isolated. The products are similar to the known scuteparvin and are characterized by being trans-cinnamoyl derivatives. Structures and stereochemistry were determined by intensive NMR investigation. Six of the products form three pairs of epimers at C-13. Hastifolins A-C showed significant antifeedant activity.

Optimal Flight Path Determination in Turbulent Air: A Modified EKF Approach

2017

By using the Extended Kalman Filter an accurate path following in turbulent air is performed. The procedure employs simultaneously two different EKFs: the first one estimates disturbances, the second one affords to determine the necessary controls displacements for rejecting those ones. To tune the EKFs an optimization algorithm has been designed to automatically determine Process Noise Covariance and Measurement Noise Covariance matrices. The first filter, by using instrumental measurements gathered in turbulent air, estimates wind components. The second one obtains command laws able to follow the desired flight path. To perform this task aerodynamic coefficients have been modified. Such a…

Dynamic Behaviour of an Axially Moving Plate Undergoing Small Cylindrical Deformation Submerged in Axially Flowing Ideal Fluid

2011

Abstract The out-of-plane dynamic response of a moving plate, travelling between two rollers at a constant velocity, is studied, taking into account the mutual interaction between the vibrating plate and the surrounding, axially flowing ideal fluid. Transverse displacement of the plate (assumed cylindrical) is described by an integro-differential equation that includes a local inertia term, Coriolis and centrifugal forces, the aerodynamic reaction of the external medium, the vertical projection of membrane tension, the bending resistance, and external perturbation forces. In the two-dimensional model thus set up, the aerodynamic reaction is found analytically as a functional of the cylindri…
