The chemical composition of propolis from Bulgaria, Turkey, Greece and Algeria was investigated by GC-MS. All of them contained mainly flavonoids and esters of caffeic and ferulic acids, which indicated that their main source are buds of poplars of the taxonomic section Aegieros. Some Turkish samples contained a low percent of diterpenic acids, while in Algerian samples significant amounts of a...

This paper deals with a new indicative features recognition system for Arabic which uses a set of a simplified version of sub-neural-networks (SNN). For the analysis of speech, the perceptual linear predictive (PLP) technique is used. The ability of the system, has been tested in experiments using stimuli uttered by 6 native Algerian speakers. The identification results have been confronted to ...

The Algerian economy is an example of a high level of rentierism, while the Egyptian economy shows a low/moderate level of rentierism. The ARDL bounds test approach was used upon annual time series data from 1965 to 2010. The results suggest cointegration for both countries. Bi-causality between energy consumption and growth in the long run was found. For Algeria there is a reversed (negative) ...
