- Fasciolosis caused by Fasciola spp. (Platyhelminthes: Trematoda: Digenea) is considered the most important helminth infection of ruminants in tropical countries, causing considerable socioeconomic problems. In the endemic regions of the North of Iran, Fasciola hepatica and F. gigantica have been previously characterized on the basis of morphometric differences, but the use of molecular markers is necessary to distinguish exactly between species and intermediate forms. Samples identified morphologically as Fasciola sp.
Larval forms of the genus Hysterothylacium have been previously reported in teleost fish from the North African coasts of central Mediterranean Sea by morphological analysis.

This study describes patterns of geographic variation in morphometric characters of the African green toad Bufo boulengeri, from Tunisia (11 populations). Body size differences of 89 specimens were analysed with univariate statistics, and body proportions with multivariate methods. Among-groups differences in morphometric characters included both size and shape. Southern populations were found to have larger body size than northern ones, and there was an association between climatic factors and morphological characters.
In this course, we will cover the basic of information retrieval and how to build a search engine. The course will cover boolean retrieval model, indexing and structures to store documents, vector space model, evaluation of retrieval systems, probabilistic retrieval models, relevance feedback and query expansion, text classification, link analysis and web search.
(3 credit hours) The course offers a fairly comprehensive introduction to the exquisitely complex literature of the British Romantic Period (1789-1830). The students will be introduced to a broad selection of texts by the most prominent poets, novelists, and thinkers of English Romanticism, as well as their relevant historical, cultural, political and aesthetic milieu.
Two new high repetitive DNAs were isolated from Discoglossus pictus genomic DNA digested with StuI. Sequence analysis of clones indicated two types of repetitive units 143–148 bp and 170–177 bp long, respectively. Southern blot analyses show ladders of bands indicating that both repetitive units are organized in long tandem arrays and belong to two different satellite DNAs that were named Dp-sat2 and Dp-sat3. A similar ladder of bands was also produced when genomic DNA was digested with ClaI in the case of Dp-sat2, or with ScaI in the case of Dp-sat3.
