I view interactive fiction in its present stage as an immature medium capable of artistic development. [We] are at the beginning what could be explosive development [and while] games like Adventure do not yet have a generally accepted name … “Adventure games” might win out long run, much “Kleenex” is used instead “facial tissue.” (Buckles 6–9) [Adventure games] resemble Donkey Kong, Space Invad...

rockfill dams are accounted as useful measures in watershed management projects. how-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures however; there is no general relationship to estimate the sediment transport rat...

The rootes of Chinese sage, Salvia miltiorrhiza Bunge (labieteae) are used to prepare an important traditional medicine in the Chinese pharmacoepia, Dan Shen. Indeed, related members of this genus are common traditional medicines throughout the world, making Salvia species the targets of intense phytochemical investigations. The active constituents of these species have been reported to be seve...

Accurate estimate of flood flows at selected return periods is a fundamental step in flood control and design of hydraulic structures. Due to the inadequacy or unavailability of flood flow records in several western catchments of Iran, traditional regional flood frequency methods lead to remarkable estimate errors, particularly for long return periods. In this research, discriminant analysis is...

A general synthetic route to the synthesis of imidazoles has been developed using nano SbCl5/SiO2 under solvent-free conditions. The multi-component reactions of aldehydes, benzil and ammonium acetate were carried out to afford some trisubstituted imidazole derivatives. This method provides several advantages like simple work-up, environmentally benign, and shorter reaction times along wi...

Metastructures and metaterms have been proposed to extend Prolog systems 6, 5]. They enable special purpose uniications to be speciied. They are useful to implement for example coroutining and new domains of computation. In both cases, information is attached to variables, which then are encoded with metaterms or metastructures. This information must be taken into account during uniication. Pro...

Consider two graphs G1 and G2 on the same vertex set V and suppose that Gi has mi edges. Then there is a bipartition of V into two classes A and B so that for both i = 1, 2 we have eGi(A,B) ≥ mi/2 − √ mi. This answers a question of Bollobás and Scott. We also prove results about partitions into more than two vertex classes.
