In order to facilitate sentiment analysis of Persian text, we’ve designed and implemented an algorithm which aims to detect words with negative polarity. Currently most sentiment analysis algorithms depend mainly on polarity datasets. However, since negative prefixes in Persian are only attached to a semantically positive base (shaghagi, 2002), we have incorporated a negative prefix detection t...

This paper introduces PersPred, the first manually elaborated syntactic and semantic database for Persian Complex Predicates (CPs). Beside their theoretical interest, Persian CPs constitute an important challenge in Persian lexicography and for NLP. The first delivery, PersPred 11, contains 700 CPs, for which 22 fields of lexical, syntactic and semantic information are encoded. The semantic cla...

The Persian Gulf and its shores are important and strategic areas with a large variety of fish species. Betanodavirus infection is known to be a serious threat to susceptible fish and causing economic damages to the fisheries and fishing industry. Concerning to isolation and confirmation of VNN virus in the Mullet fish (Chelon aurata and C. saliens) in the Caspian Sea and its damages on Mullet ...

BACKGROUND During the 1990-1991 Gulf War, approximately 700,000 U.S. troops were deployed to the Persian Gulf theater of operations. Of that number, approximately 100,000 have presented medical complaints through various registry and examination programs. OBJECTIVES Widespread symptomatic illness without defining physical features has been reported among veterans of the 1991 Gulf War. We asce...

The status of Indo-Pacific Briareum species (Cnidaria, Octocorallia, Briareidae) is reviewed by presenting their sclerite features and habitus descriptions. Following the re-examination of type material, museum specimens and newly collected specimens, a species identification key is provided. The species distributions are discussed and updated distribution ranges are depicted. Moreover, a new t...

persian sturgeon, acipenser persicus is a native, commercially important and highly steemed fish species in the caspian sea. in this study, effects of nodularin (nodln), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of a. persicus were studied. nodularin was produced in high amounts by nodularia spumigena, a cyanobacterium species during the algal bloom in the caspian sea and was...

we estimated the genetic diversity and population structure of persian sturgeon across six regions of caspian sea along the coast of iran using eight dna microsatellite loci. full genotypes were obtained for 195 individuals of persian sturgeon. significant differences were detected between a. persicus specimens collected from sefidrud river (p≤0.0001) and those collected from the southern fishe...

In this study, genetic differences and phylogenic relationships among six Mugilidae species (Mugil cephalus, M. capito, Liza subviridis, L. saliens, L. aurata, Valamugil buchanani) were determined using PCR-sequencing. M. cephalus, L. subviridis, and V. buchanani from the Persian Gulf and Oman Sea, and L. aurata and L. saliens from the Caspian Sea were col-lected. Samples of an imported, Egypt...
