Aim: Angiogenesis is an essential prerequisite for endometrial development and differentiation. Absence of optimum endometrial perfusion can be one of the important reasons behind the patients with unexplained infertility. The present study was undertaken to identify the endometrial vascularity by Doppler and find its relation with serum VEGF in infertile women. Materials And Methods: 60 Patien...

The study of planktonic foraminifera of the Ilam and Gurpi formations at Sarvestan area (SE of Shiraz) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Seven biozones were determined. Biozones I (Dicarinella concavata zone) and II (Dicarinella asymetrica zone) belong to the Ilam Formation and indicate the Late Coniacian-Early Santonian...

The litho-and biostratigraphy of Upper Cretaceous (Gurpi Formation) has been investigated within a well-exposed section at the northern limb of Pey zard anticline, Abnow area, Southern Iran. The studied section consists mainly of grey marl, calcareous pyritic shale, and argillaceous limestones. The Formation unconformably overlies Sarvak Formation and the Tarbur Formation overlies it unconforma...

We present in this paper an automatic system of handwritten isolated Arabic characters recognition. It is based on a pretopological approach. The approach is based on a criterion constructed from a pretopological pseudo-distance that allows to measure the degree of dissimilarity between the characters. On a database of 6188 handwritten isolated Arabic characters, the experimental results show t...

The proposal of acoustic neutrino detection is living a renaissance: the interest in ultra high energy neutrino detection, the fast improvements of deep sea technology and the availability of large deep sea research infrastructures are the three main ingredients to explain the new interest in this technique. The status of simulation work, medium studies, sensor developments and first results fr...

Democratic theory and practice underwent something of a renaissance in the late twentieth century. The spread of liberal democratic political systems was accompanied by two other trends that have the potential to transform the shape of politics: the rise of environmental movements and increased public use of the Internet.
