Cell growth and flavonoid production in cell suspension cultures of Glycyrrhiza inflata Batal were investigated under various initial inoculum densities, and sucrose and nitrogen concentrations to develop an optimization method for an improved flavonoid production. Both biomass accumulation and flavonoid production exhibited an "S" curve in one culture cycle, with the greatest value obtained on...

One hundred twenty species of aleocharine beetles (Staphylinidae) are recognized in the province of Saskatchewan. Sixty-five new provincial records, including twelve new species and one new North American record, are presented. Oligota inflata (Mannerheim), a Palearctic species, is newly recorded for North America. The following twelve species are described as new to science: Acrotona pseudopyg...

Carnivorous aquatic plants, genus Utricularia (Lentibulariaceae), capture small aquatic organisms, such as rotifers, copepods, and cladocerans, by means of anatomical structures named bladders. The present study aimed to determine prey size and composition in U. gibba and U inflata, which were collected from a small lake and an herbaceous wetland, respectively, located in Paria Peninsula (Sucre...

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...
