During the search for geographical information in web pages, people are geo-referred with toponyms (place names) instead the use of coordinates. The conceptions of places are often complicated ambiguous and different in different time. When gazetteers are utilized as background knowledge in geographic information retrieval (GIR), they are limited because of their poor geographic semantics. Ther...

The breeding system of Anacyclus linearilobus, an annual and endemic species restricted to dune ecosystems the Algerian coast were assessed through effect self-fertilization intra- inter-population artificial crosses on probability producing viable seeds in 20 individuals from two populations a common garden. was determined for each individual by self-incompatibility index (ISI). These results ...

The demographic history of human populations in North Africa has been characterized by complex processes of admixture and isolation that have modeled its current gene pool. Diverse genetic ancestral components with different origins (autochthonous, European, Middle Eastern, and sub-Saharan) and genetic heterogeneity in the region have been described. In this complex genetic landscape, Algeria, ...

The objective of this study was to determine the level of adoption within the Algerian poultry farms (broiler chickens, laying hens) of a range of standard biosecurity practices (isolation, traffic control, decontamination, vaccination...). Quantitative and qualitative evaluation of the biosecurity in the poultry houses has been analyzed thanks using method developed by the French Food Safety A...

In this report we describe a case of bowenoid papulosis (BP) on the face of a 44 year old Algerian man. To our knowledge this is the first reported case of isolated extragenital BP. The presence of type 16 human papilloma virus was demonstrated by in situ hybridisation. This case underscores that multiple HPV-induced severe intraepithelial neoplasia, the so-called BP, is not restricted to the a...

A 23 year old Algerian male was admitted to hospital due to intermittent mucopurulent and blood-stained sputum of 2 yrs duration. Temperature, blood pressure, cardiorespiratory and abdominal examination were normal. Laboratory findings showed 480 eosinophils·ml-1 in peripheral blood. The lateral and posteroanterior (PA) chest roentgenograms are shown in figures 1 and 2. Empirical treatment with...

A pollen analysis of Algerian honey was conducted on a total of 10 honey samples. The samples were prepared using the methodology described by Louveaux et al., that was then further adapted by Ohe et al. The samples were subsequently observed using light microscopy. A total of 36 pollen taxa were discovered and could be identified in the analyzed honey samples. Seventy percent of the studied sa...

Djendjen River is one of the largest rivers in the region of Jijel (Algeria). Human activities such as urban discharges, industrial, agricultural, and livestock have significant effects on the quality of water. The present study attempts to evaluate the quality of water along the banks of the Djendjen River at different sampling sites, using physico-chemical and bacteriological methods. The col...

BACKGROUND Data on cancer mortality in North African migrants to France (the largest foreign-born community in the country) are presented, providing useful insights both into cancer patterns in North Africa and their changes following migration. METHODS The cancer mortality in migrants from North Africa (Algeria, Morocco, Tunisia and Egypt) resident in France relative to that of the local-bor...
