The antimicrobial activity of the methanol extracts of the dried flowering aerial parts of Stachys byzantina, S. inflata, S. lavandulifolia and S. laxa (Labiatae) were studied using the disc diffusion method and determination of minimum inhibitory concentration (MIC) values against Staphylococcus aureus, Streptococcus sanguis, Escherichia coli, Pseudomonas aeroginosa, Klebsiella pneumoniae, Asp...

Preparative reversed-phase HPLC analysis of the methanol extract of the aerial parts of Stachys bombycina (Lamiaceae) afforded two acylated flavonoids glycosides, chrysoeriol 7-O-[6-O-acetyl-beta-D-allopyranosyl]-(1 --> 2)-beta-D-glucopyranoside (1) and apigenin 7-O-beta-D-(6-p-coumaroyl)-glucopyranoside (2), the former being a new natural product. The structures of these compounds were elucida...

It is shown that any sets of linguistic values of linguistic variables can be axiomatized, which leads to a notion of hedge algebras. Some intuitive properties of linguistic hedges, which are a basis of the axiomatization of the hedge algebras, are discussed informally. The characteristics of the hedge algebras depend on such a discussion and they seem to reflect the natural structure of sets o...

This paper examines the causes and consequences of hedge fund activism. Hedge funds target profitable and healthy firms, with above-average cash holdings. The target firms earn significantly higher abnormal stock returns around the initial 13D filing date than a sample of control firm. However, they do not show improvements in accounting performances in the year after the initial purchase. Inst...

This paper relates to the construction and testing of a solarpowered golf cart and the future incorporation of a fuel cell system to the existing solar cart. The prototype built in 2004 [fig 1] proved to be very successful. The combination of unique features such as the tracking of the sun resulted in the increase of output power with respect to other solar carts. In addition, the cart turns in...
