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 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...

Stachys lavandulifolia is used as the herbal tea and its wide and potent medical effects have been reported for the extract in animal studies. This study aimed to find the safety profile of the extract to find the appropriate doses for further human studies. The aerial parts of the plant were air-dried and the hydroalcoholic extract was obtained and concentrated by percolation method with 140 m...

The present study was conducted to evaluate the efficacy of wood betony (WB), Stachys lavandulifolia extract on growth performance and some immune responses in common carp, Cyprinus carpio. Different concentrations of the WB extract 0, 2, 4 and 8% (g per 100 g of diet) were added to commercial diet. Each treatment was randomly assigned to triplicate groups of fish having average initial weight ...
