    Twisted Conformal Algebra and Quantum Statistics of Harmonic Oscillators (2014)
    Hindawi
    Details
    Publication Date: 2014-01-01
    Description: We consider noncommutative two-dimensional quantum harmonic oscillators and extend them to the case of twisted algebra. We obtained modified raising and lowering operators. Also we study statistical mechanics and thermodynamics and calculated partition function which yields the free energy of the system.

    Feeding regime of Persian sturgeon (Acipenser persicus) in the south Caspian Sea (2018)
    Details
    Publication Date: 2021-05-19
    Description: Feeding regime of the Persian sturgeon in the southern basins of the Caspian Sea was studied in summer and winter 2006 in three provinces Guilan, Mazandaran and Golestan. We caught 52 fish specimens in 85 sampling sites varying in depths from 2-100 m using bottom trawls. The average weight and length of fish specimens were 332.81+1 g and 37.69±1 cm, respectively. The alimentary tract of fishes were analyzed and 11 food items including Gobiidae, Gammaridae, Mysidae, Nereidae, Ampharetidae, Pseudocumidae, Clupeidae, Syngnathidae, Scrobicularidae, insects and Cardiidae were identified. The highest feed diversity was observed in Mazandaran province (9 items) and the lowest in the Golestan province (4 items). Although Nereids showed the highest percentage of benthic organisms (49%) but they were of secondary and tertiary importance in the fish diet qualitatively. Comparison of Fulton's condition factor of fishes in the three provinces showed a similar pattern (0.3〈1(〈0.4). A Tukey test revealed that there were no statistically significant differences between condition factor and gastro-somatic index in the three provinces while Vacuity index (CV) showed significant statistical differences among the provinces.

    A survey on some risk factors and evaluation of their impacts on streptococcosis incidence in rainbow trout farms in Fars province (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Streptococcosis is an infectious bacterial disease that causes huge economic losses in cold water aquaculture industry. Disease outbreak was experienced in some of provinces farms in recent years. Fars Province, has produced 7,000 tons of cold-water fish. According to Streptococcosis report in 1381 from the province and Proceedings have been performed during 10 years against disease and also economic losses impact of disease on rainbow trout production, risk assessment of Streptococcosis conducted on the plan. In this study, of 586 sick fish (have symptoms) studied 230 fish (39.24%) Streptococcus and (26.62%) gram negative bacteria were isolated. Of 754 healthy grower fish and fry (with no clinical signs) 10 fish or fry (1.32%)infected with streptococcus and 60 fish or fry(7.95%) infected with gram negative bacteria (Yersinia ruckeri , Pseudomonas , entrobacteriaceae).According to biochemical tests and molecular examinations , isolated Streptococcus identified as Lactococcus garvieae , Streptococcus iniae and Streptococcus sp. Furthermore some physical and chemical parameters measured and aerobic bacteria of selected farm water counted. These factors effects on disease incidence and changes were evaluated by applying logistic regression.

    Heavy metals Cu, Zn, Cd and Pb in tissue, liver of Esox lucius and sediment from the Anzali international lagoon- Iran (2021)

    Description: Levels of contaminants in fish are of particular interest because of the potential risk to humans consuming them. This paper examines the levels of cadmium, lead, zinc and copper in liver and muscle tissue of Esox lucius and in sediments from the Anzali international wetland in Iran. The wetland is a nursery and feeding habitat for fish species both from the lagoon and the Caspian Sea, which are consumed by the local inhabitants and others. Eleven main rivers discharge agricultural, industrial, urban and municipal wastes into this wetland. Twenty five Esox lucius specimens, with a mean weight of 804.6±121g and mean length of 430.7± 2mm were collected from the wetland by multi mesh gill nets in September and December 2007.. The age was determined from scale samples according to the annual ring structure. Average concentrations of Cd, Cu, Pb and Zn accumulated in the mid-dorsal muscle tissue (filleted and skinned) of fish were 0.001, 0.21±0.02, 0.13±0.01 and 2.55±0.18 µg.g-1, respectively. The concentrations of these metals in liver samples were Cd: 0.0014± Cu: 0.96± 0.61, Pb: 0.11 ± 0.04 and Zn: 2.46±1.5 µg.g-1. Significant positive correlations were detected between Zn and Cu with body weight, while negative correlations were found between Pb and body weight. The concentrations of Zn, Cu and Cd were below the maximum allowable concentrations for fish proposed by WHO and MAFF (safe for human consumption) but concentration of Pb exceeded the standard levels.
