A Novel Scheme for Intelligent Recognition of Pornographic Images

Harmful contents are rising in internet day by day and this motivates the essence of more research in fast and reliable obscene and immoral material filtering. Pornographic image recognition is an important component in each filtering system. In this paper, a new approach for detecting pornographic images is introduced. In this approach, two new features are suggested. These two features in combination with other simple traditional features provide decent difference between porn and non-porn images. In addition, we applied fuzzy integral based information fusion to combine MLP (Multi-Layer Perceptron) and NF (Neuro-Fuzzy) outputs. To test the proposed method, performance of system was evaluated over 18354 download images from internet. The attained precision was 93% in TP and 8% in FP on training dataset, and 87% and 5.5% on test dataset. Achieved results verify the performance of proposed system versus other related works

Population genetic study on Tenualosa Ilisha from Persian Gulf (Khouzestan region)

Information on the genetic structure of fish populations is useful for identification of stocks, management for sustainable exploitation and preservation of genetic diversity. The most important objective in population genetics is discrimination between populations within their distribution areas. The invention of polymerase chain reaction has created new possibilities for exploration of these differences in fish populations. One of these PCRbased methods is Random Amplified Polymorphic DNA (RAPD) which uses short oligonucleotide primers of arbitrary sequences to amplify discrete regions of the genome. The most important features of this method are: obtaining a large number of polymorphic DNA bands using tiny amounts of DNA without necessity of cloning or previous knowledge of DNA sequence. Ilisha shad (Tenualosa ilisha) which is locally known as Soboor is an anadromous fish living in sea shores, estuaries and downstream of rivers and migrate to upstream for spawning. The aim of this research was to study genetic structure of soboor in Khuzestan waters, including Karoon, Arvadrood and Bahmashir rivers, Persian Gulf (Sea) as well as Iraqi samples (caught from Shat-Al-Arab river), by using RAPD technique. For this purpose, fifteen random decamer primers were initially applied on DNA samples of 4 individuals from each region. After optimizing PCR condition, nine primers with best results were selected from which 58 polymorphic loci were obtained on 60 specimens (12 specimens from each geographical region). RAPD data were obtained by scoring 1 and 0 for presence or absence of polymorphic bands, respectively. RAPDPLOT, RAPDDIST and POPGENE computer Software were used to analyze the RAPD data. Canonical discriminant analysis was deployed for statistical analysis of the data. Maximum and minimum genetic distances were found between samples from Iraq and Sea (0.2870) and Arvandrood and Bahmanshir (0.1042), respectively. The UPGMA dendrogram showed that the samples from Karoon and Sea form a clade whereas samples from Iraq, Arvandrood and Bahmanshir rivers form another clade suggesting the hypothesis that there are two Iranian and Iraqi populations of this species and these fish select their own specific river for spawning. According to this hypothesis the specimens from Sea would destine Karoon as their spawning river. On the other hand, two other separate groups could be corresponded to Tigris and Euphrate rivers in Iraq. Moreover, canonical discriminant analysis indicates that samples from four geographical regions are statistically different from each other and high correlation among data was found within each region (P<0.01) suggesting that Tenualosa ilisha is a schooling species. According to the above two hypotheses and considering the distribution of specimens in phylogenetic tree it can be concluded that Bahmanshir river is a specific pathway for those fish heading Karoon river for spawning whereas Shat-Al-Arab population uses both Bahmanshir and Arvandrood rivers to reach Shat-Al-Arab. To verify these three hypotheses further studies are needed

In three year period, 1378 to 1381, fish samples from four stations were transferred a live to the lab. Water samples also were taken and tested for some of the physicochemical factors. From a total of 1914 fish examined, 1190 showed parasitic infestation and bacterial infections (62.2%). Infestation study, infestation with these parasites have been found: Ichthophthirius, cryptobia, Trichodina, Costia, Hexamita, Dactylogyrus, Gyrodactylus, Lernea, Bothrio cephalus, Diplostomum and Capillaria. Also some species of Aeromonas, staphylococcus, Moraxella, Pectobacterium, Flavobacterium, Citrobacteria, pasteurella, Psedomonas and Alcaligenese were identified in the samples, which normally occur in Water, but in some conditions (High pH, temperature and ammonia) could cause disease and lesions specially in gills. Infestation with dactylogyrus and Gyrodactylus was found in all four kind of fishes with different infestation rate. But the highest infestation rate with dactylogyrus was in silver carp (55.2%) and lowest in common carp (14.6%). The highest infestation rate with gyrodactylus was in grass carp (42.4%) and lowest in common carp (10.6%). Ich, Bothrio cephalus and capillalia were found only in common carp and grass carp. Infestation with adult lernea and copepodid stage of lernea had greater percentage in the gills and derm of grass carp. The data showed infestation with this parasites (especially protozoans and lernea) and bacterial infection had occurred in all seasons especially in C area

Effect of salinity on spawning of yellow fin sea bream (Acanthopagrus latus) in spawning tanks

Salinity effects on brooders spawning, growth and survival rate of yellow fin sea bream (Acanthopagrus latus) fingerlings was studied in Khouzestan Marine Fishes Research Station (Bandar-e Imam) in 2002- 2003. More than 200 brooders were caught in Mahshar creeks using hook, and 6 males and 3 females of brooders were introduced to each 4 tons tank. The experiments were carried out using 3 salinity treatments (30±1, 35±1 and 40±1 ppt) in 3 replications. Survival rate of brooders in 4 tons tanks during late January to 4^th April was estimated more than %90 in all salinities and the maximum rate was observed in 30 ppt treatment. Spawned brooders percentage in 40 ppt was more than the two other salinities, and spawning occurred in all three replications of this treatment. In all treatment, spawning started from early march (late lunar month) at 19~'C and continued at 23°C. Duration and replication of spawnings in 40 ppt were more than other salinities, and last about 20 days. Released eggs (2461046), amount of eggs production per day (66413), average number of eggs per brooder (312914), and average eggs per kg body weight (649460) were found in 40 ppt more than other salinities. Floating eggs ratio was more than %90 in 40 ppt and it was significantly different to the others. Fertilization and hatching rates in 40 ppt treatment (86.7, 67 respectively) were more than 30 and 35 ppt but there was no significant difference. All spawnings cases , released eggs hatched
