The mature spermatozoa of Perinereis macropus were investigated by transmission electron microscopy. The spermatozoon is composed with a large anterior part (head), a short middle piece and a long flagellum. The head contains a large acrosomal complex with a convex acrosomal vesicle, a subacrosomal space, a fibrillar crown and an acrosomal rod which(More)
An efficient and above all cheap solutions, biometrics provide extensive information in access control applications. 3D mode provides great new opportunities in this sector in recent years. Firstly the paper discusses the formal work done in this domain discussing approach based on curvature calculation, alignment of surfaces, feature selection and facial(More)
In eukaryotic genomes, tandem repeats represent two or more adjacent copies of pattern nucleotides. They are the most principal cause of various genetic diseases. So, it's very important to locate and define them. During the last decade, many tools (TRF (Tandem Repeats Finder), Mreps, Sputnik, ATRHunter equicktandem, etandem...) have been developed to(More)
The polychaete Perinereis macropus (Claparède, 1870) (Nereididae) is present in the Gulf of Gabes, but its reproductive biology is unknown. An intensive study was conducted from August 2004 to July 2005 to characterize the life cycle of a population in the mouth of wadi Ferd in Gabes. The examination of sexual products allows us to describe the(More)
