in coastal areas, hydrodynamic factors make changes in shorelines geomorphology. this can affect coastal facilities and cause hazards to human societies in the areas. this study has investigated the influence of wave and tide properties on khamir port, hormoz strait in coast of persian gulf. the purpose of the study is to make a mathematical regional and local modeling of water level fluctuatio...

In order to find new sources of natural antioxidants, the antioxidant capacities of 50 medicinal plants associated with treatment of rheumatic diseases were systemically evaluated using the ferric-reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays, and their total phenolic contents were measured by the Folin-Ciocalteu method. Their antioxidant activities ...

The aim of this study is to optimize extraction parameters of phenolic compounds from one variety of Algerian table grapes. The effect of different solvents: distilled water, acetone (20, 40, 60 and 80%), methanol (20, 40, 60 and 80%) and ethanol (20, 40, 60 and 80%), temperature (25, 40, 50, 60 and 70°C), time (30, 60, 90 and 120 min) and four successive extractions were tested. It was found t...

AlSat-1, the First Algerian National Satellite, and the first of five microsatellites in the Disaster Monitoring Constellation (DMC), was launched on the 28 November 2002 from Plesetsk. AlSat-1 was joined by SSTL built Microsatellites for Nigeria, the United Kingdom and Turkey with the second DMC launch on the 23 September 2003 and the fifth microsatellite for China was launched into the same o...

The aim of this study, was to characterize the extended-spectrum-β-lactamases (ESBLs) producing clinical strains of Escherichia coli isolated between January 2009 and June 2012 from Algerian hospitals and to determine the prevalence of 16S rRNA methylase among them. Sixty-seven ESBL-producers were detected among the 239 isolates included: 52 CTX-M-15-producers, 5 CTX-M-3-producers, 5 CTX-M-1-pr...

A survey of aphids was carried out during the period 2008-2011 in different regions of Algeria by collecting and identifying aphids and their host plants. Aphids were collected from 46 host plants. Forty-six species were reported including thirty-six species which were recorded for the first time in this country and thirty species which were recorded for the first time in the Maghreb (North Afr...

The rapid development of the ICT compels us to train both teachers and students in new skills that allow adapting to the new learning situations; tending to become more and more complex. By carrying a survey among 240 Algerian university teachers, we tried to describe the importance given to ICT in education; while emphasizing their impact on the techno-pedagogical skills of the higher educatio...

Introduction We report a unique case in a 17 year old male patient of Algerian origin with two rare genetic conditions with overlapping clinical symptoms. Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by sporadic, paroxysmal attacks of fever and serositis. Hereditary coproporphyria (HCP) is one of the type of acute hepatic porphyria resulting in neuroviscer...

Aims Both human and non-human determinants have shaped Mediterranean forest structure over the last few millennia. The effects of recent human activities on forest composition, however, remain poorly understood. We quantified changes in forest composition during the past century in the mixed forests of Quercus suber (cork oak) and Q. canariensis (Algerian oak), and explored the effects of fores...
