Understanding the factors explaining the observed patterns of genetic diversity is an important question in evolutionary biology. We provide the first data on the genetic structure of a Mediterranean octocoral, the yellow gorgonian Eunicella cavolini, along with insights into the demographic history of this species. We sampled populations in four areas of the Mediterranean Sea: continental Fran...

This paper presents the results of an evaluation of acoustic comfort such as background noise and reverberation time in teaching rooms in Height National School of Civil Engineering, Algeria. Four teaching rooms are evaluated: conference room, two classroom and amphitheatre. The acoustic quality of the classrooms has been analyzed based on measurements of sound pressure level inside room and re...

OBJECTIVE We have conducted the first study of the association of interleukin (IL)-10, tumor necrosis factor alpha (TNF-α), and IL23R-IL12RB2 region single nucleotide polymorphisms (SNPs) with Behçet's disease (BD) in Western Algeria. METHODS A total of 51 BD patients and 96 unrelated controls from West region of Algeria were genotyped by direct sequencing for 11 SNPs including 2 SNPs from th...

This third part of the lecture series deals with the question: Who will pay for your retirement? For Western Europe the answer may be " nobody " , but for Algeria the demography looks more promising.

BACKGROUND Bovine Tuberculosis is prevalent in Algeria despite governmental attempts to control the disease. The objective of this study was to conduct, for the first time, molecular characterization of a population sample of Mycobacterium bovis strains isolated from slaughter cattle in Algeria. Between August and November 2007, 7250 animals were consecutively screened at the abattoirs of Algie...

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, ...

In this chapter, the authors present an improvement to the interactions between MAC (Medium Access Control) and TCP (Transmission Control Protocol) protocols for better performance in MANET. This improvement is called IB-MAC (Improvement of Backoff algorithm of MAC protocol) and proposes a new backoff algorithm. The principle idea is to make dynamic the maximal limit of the backoff interval acc...

BACKGROUND Argasid ticks (soft ticks) are blood-feeding arthropods that can parasitize rodents, birds, humans, livestock and companion animals. Ticks of the Ornithodoros genus are known to be vectors of relapsing fever borreliosis in humans. In Algeria, little is known about relapsing fever borreliosis and other bacterial pathogens transmitted by argasid ticks. METHODOLOGY/PRINCIPAL FINDINGS ...

Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...
