    Discretization of Topological Spaces (2016)
    Oxford University Press
    Details
    Publication Date: 2016-12-01
    Description: There are several compactification procedures in topology, but there is only one standard discretization, namely, replacing the original topology with the discrete topology. We give a notion of discretization which is dual (in the categorical sense) to compactification and give examples of discretizations. Especially, a discretization functor from the category of α -scattered Stonean spaces to the category of discrete spaces is constructed, which is the converse of the Stone–Čech compactification functor. The interpretations of discretization in the level of algebras of functions are given.

    Population genetic structure of silver pomfret, Pampus argenteus, in Persian Gulf and Oman Sea in Iran and Kuwait waters by using10 Microsatellite Markers (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The silver pomfret, Pampus argenteus, is distributed in Indo-western pacific ocean, especially in Persian Gulf and Oman sea, and although is widely commercially exploited, the genetics structure of this species is not clear completely. In the present study, the genetic diversity and population structure of Pampus argentus in the Persian Gulf and Oman Sea were investigated using microsatellite DNA markers. Genomic DNA from 125 specimens was extracted and PCR amplification performed. Seven loci with reasonable polymorphism were amplified. The results showed that average of observed heterozygosity was ranged from 0.54 while expected heterozygosity was 0.67. After applying the Hardy-Weinberg Equilibrium (HWE) test, some loci were found to be significantly deviated from HWE in some populations in which deficiency of heterozygotes was apparent. Population differentiation observed among all populations (P 0.01). The population differentiation (Fst) value between Kuwait and bushehr was the highest and significant (0.087) and between Chabahar and Bushehr (0.021) was the lowest and significant. Genetic distance analysis showed that the largest distance (0.269) was between Khuzestan and Chabahar and the smallest distance (0.075) was between Bushehr and Chabahar. The reported results could be of interest for management and conservation programmes of this species in the Persian Gulf and Oman Sea.

    Efficiency of shrimp trawl nets polyamide and polyethylene with standard mesh in the coastal waters of Bushehr Province (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was carried out in August – september 2009 in Bushehr province waters. Two different shrimp bottom trawls were used in which were woven by Poly Amid and Poly Ethylene with mesh sizes( stretched ) of 50 mm and sack with 35 mm. Also 2 different vessels of two dhows and one steel ship each with 26 and 30 hauls were used and taken in to comparison from point of obtained results. Total catch of PA and PE trawels were 4592 and 5535 kg of which the ratio of shrimp catch and bycatch for PA trawl was 32.4 and 67.6 % respectively; and for PE trawl was 34.2 and 65.8%. Total catch of PA and PE trawls of steel trawler ( ship ) were estimated 3158.0 and 4784.7 kg, respectively, of which the shrimp/bycatch ratio was 6.6 : 93.4%. There was a higher amount of bycatch for PE comparing to PA trawl (p〈 0.05). on the other hand the decrease of shrimp and bycatch for PA comparing to PE dhow trawlers were 21.3 and 15.0% and for ship were 34.6 and 34.0% respectively. The weight ratio is 1:15 i.e . in PE ship trawl , in proportion to on kg shrimp, 15 kg bycatch was harvested. it is proposed to standardize the mesh size and also to do obligtory the instal of squared mesh size panel .
