Looking into a text: an analysis of a document "Min al-Gaza'ir al mugahida ila huggag bayt Allah al-haram (1957)" of the Gabhat al-tahrir al-watani a…

This study offers a particular interpretation of an important document in Arabic language of 1957 entitled “Min al-Gaza'ir al mugahida ila huggag Bayt Allah al-haram". The object of the analysis is a historical record: not a simple datum, but a fragment of universe. In fact it needs to be grasped through the means of questioning; and it is clear that the answer and/or the answers will be given in accordance with the used procedure; the tools that I employ as a scholar of the field and the language I resort to. In this sense, I consider worth noting that Contemporary history of Algeria is here intended as an integral part of the Arab-Islamic World; even if some representative Algerian histor…
Isolation, characterization and determination of biotechnological potential of oil-degrading bacteria from Algerian centre coast
2019
Aims The Algerian coastline is exposed to several types of pollution, including hydrocarbons. The aim of this work was to isolate oil-degrading bacteria and to explore the intrinsic bioremediation potential of part of its contaminated harbour. Methods and results A collection of 119 strains, capable to grow on mineral medium supplemented with hydrocarbons, were obtained from polluted sediment and seawater collected from Sidi Fredj harbour (Algiers). Twenty-three strains were selected for further studies. Sequencing of the 16S rRNA gene showed that most isolates belong to genera of hydrocarbonoclastic bacteria (Alcanivorax), generalist hydrocarbons degraders (Marinobacter, Pseudomonas, Gordo…
Dire institutionnel et espaces de langage - le cas de l'Algérie - Essai d'une sémio-didactique
1992
This thesis is 1) an discourse analysis of the institution' texts (Algeria, in the eighties) + analysis of the young people in secondary school (part I) ; 2) a semiotic analysis of spaces in Algeria (country, village, secondary school). The results : we showed many contraints in a collective speech, through 2 dominant themas : time, action ; and 2 recessive themas : subject (speaker), mirror. So, education and didactic perspective are useful.
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…
2014
The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
