In this study, tetranitrocarbazole (TNC) interaction with boron nitride nanocluster was evaluated by infrared (IR), natural bond orbital (NBO) and frontier molecular orbital (FMO) computations. The negative values of adsorption energy, enthalpy changes, Gibbs free energy variations showed TNC adsorption on the surface of B12N12 is exothermic, spontaneous and experimentally feasible. The negative values of entropy changes showed adsorption process is inappropriate due to aggregation in TNC complexes with boron nitride nanocage. The NBO results indicated a monovalent bond is formed between the explosive and the nano-adsorbent with SP3 hybridization and their interaction is a chemisorption. The enhancement of specific heat capacity values of TNC after its adsorption on the surface of nanocage indicated the heat sensitivity of TNC has reduced significantly. Structural parameters including the energy of HOMO and LUMO orbitals, bandgap, electrophilicity, chemical potential, chemical hardness, density and zero-point energy were also calculated and discussed. The remarkable decrease in bandgap after the TNC adsorption on the surface of B12N12 demonstrated that the electrochemical conductivity and electrocatalytic properties decreased after adsorbate interaction with the adsorbent and this boron nitride nanocage can be used for construction of new electrochemical sensor in order to TNC detection and quantitation.

According to Rumi‚ the soul of the universe itself is remote‚ trapped and killed in prison ‚such as straw and the desire to see the universe in this cage began to complain. He says all of the beauty can be seen because it is a reflection of his soul. When the soul is separated from the body‚ the body decays and the smell will spread everywhere. Therefore the soul is single, and it has no malfunction or need to drop in it. In existence‚ soul was spiritual and pure because of joining the body. Soul changes every moment‚ that we call it sensuality‚ blaming, reassuring, etc. But soul is external ‚ it's place of knowledge revelation and oracle. It is the sense of angels and separated from the body. Manuscript profile

Introduction: In general, increasing the production and exploitation of aquatic animals in the aquatic ecosystem without considering its relationship and balance with other parts of the ecosystem causes a wrong assessment of the real cost and benefits of these services to the environment and society, and in the future will have negative effects. The activities carried out in the aquaculture industry lead to a decrease in the quality of water and as a result the chemical balance in water is disturbed. On the other hand, the increase in metabolic activity in aquatic animals intensifies those effects. In the aquaculture industry, attention should be paid to quality control and monitoring methods. Knowing the basic conditions of the desired water body for the construction of breeding farms and predicting the future situation of the region based on the effluents entering is very necessary.Aim: In this study, the physicochemical conditions of Sisangan region were investigated for setting up a fish farm.Materials and Methods: In order to determine the state of sea water quality, water sample collected for one period to analyze pollution and physicochemical variables. After determining of the variables, the TRIX trophic index was calculated and the trophic conditions of the area were determined.Results: Measuring the physical parameters of water from 5 to 15 meters depth showed that the variables of temperature, electrical conductivity, salinity, oxygen and pH do not change much along the depth. The measurement of nutrients indicated that the total nitrogen in the sea in the study area varies from less than 0.1 mg/liter to 2.5 mg/liter. The amount of total phosphorus in the study range varies from less than the measuring limit of the device 0.003 mg/liter to 0.007 mg/liter. According to the measurements made in these studies, the result of calculating the TRIX index is an average numerical value of 2.3.Conclusion: The results of this study showed that the area is tropically oligotrophic and the water quality of the area is very good.

AbstractNatural and semi-natural water resources with proper planning can be used for the production of aquatic, especially fish, and it is necessary to first assess the ecological factors and production potential. Then, the optimum cage culture number in a field was calculated based on maximizing the area of the appropriate farming and taking into account the confidence interval of about 80 meters. The results indicate 80, 80 and 100 cage culture in each region for cold water cultivation, respectively. Considering the 80 meter confidence distances and the optimal number of cage culture, the method of arrangement of cold-water fish farms in Golestan Dam was determined. According to the established design, the area suitable for the cultivation of cold water is 10 hectares (20 farms with 80 cage culture), 10 hectares (20 farms with 80 cage culture) and 12 hectares (25 farms with 100 cage culture), respectively. It should be noted that the minimum depth required for the establishment of cages for fish farming should be 3.3 meters in order to be able to farming. In general, if the depth of the water at the cage's position at the time of the introduction of the baby is at least 5 to 6 meters, the area of 32 hectares and the establishment of the cage, approximately 108 tons of fish can be harvested. If the water depth of the cage is less than 4 meters, about 60 tons of salmon can be caught. Manuscript profile

  In late June 2013, because of sudden and unjustified increase in mortality of apparent healthy fish in Hasanloo dam cage culture, random sampling was convicted from a live dying and dead fishes. Forty fishes (20 alive and 20 dead fishes) from two cage with the weight of 200-300 gr were sampled. Samples were sent to private factor laboratory ice pieces for evolution. Some physicochemical parameters of Hasanloo dam water including nitrite, nitrate, ammonium, soluble solid materials, temperature, dissolved oxygen and pH was measured.  To investing the probability of bacterial, fungal and parasitic discover outbreaks sample were taken from the kidney, gills and skin of fish. The result of different investing revealed the presence of algal bloom, oxygen shortage, executive problems and fishing net fountain obstruction due to accumulation of planktons and suspended material. Because of increase in light intensity, nutritive substances level, warming of water temperature and static suability of water hydrological status, algal blooming had occurred in Hasanloo dam that not only destroyed the gills of fish but also created competition for soluble oxygen at night with some phytoplankton species causing hypoxia and death of salmon in the breeding farm. The result of general bacterial cutler was negative and mild secondary infection with S aprolegnia species was detected in PGYEA culture. The result of liver histopathology indicated the presence of hepatic ceroidosis because of non-standard diets with high levels of carbohydrates. Gill blade inflammation and hyperplasia was the observed. Due to high amounts of ionized ammonia among culture nets resolving from summer mortality syndrome.  Manuscript profile

In this investigation, the interaction of C20 and disilyne (Si2H2) fragment was explored in the M062X/6-311++G(d,p) level of theory in gas solution phases. The interaction energy was obtained with standard method were corrected by basis set superposition error (BSSE) during the geometry optimization for all molecules at the same levels of theory. Also, the bonding interaction between the C20 and Si2H2 fragment has been analyzed by means of the energy decomposition analysis (EDA). The results obtained from these calculations reveal interaction between C20 and disilyne (Si2H2) increases in the presence of more polar solvents. There are good correlations between these parameters and dielectric constants of solvents. The wavenumbers of IR-active symmetric and asymmetric stretching vibrations of Si-H groups and 29Si NMR chemical shift values in different solvents were correlated with the Kirkwood–Bauer–Magat equation (KBM). our calculations showed the good relationship between chemical shift values of 29Si NMR, IR-active symmetric and asymmetric stretching vibrations of Si-H groups and KBM solvent parameters.
