“…Although there is a report that even 11 months exposure to 37-3000ugL~1 Cd did not affect the length offish [16], many authors observed a reduction in the growth of fish under Cd exposure [17][18][19]. 2.5mgL~1Cd did not reduce the length and weight of fish in the present investigation.…”

Common carp Cyprinus carpio was chronically exposed to cadmium (2.5 mgL -1 ) and combined treatment of cadmium and KMnO 4 (1 mgL -1 ) for 90d in outdoor artificial enclosures. Although total and filtrable (dissolved) cadmium of water gradually decreased during the experiment whole body concentration of cadmium in common carp progressively increased in both treatments. Combination of KMnO 4 with cadmium marginally reduced the accumulation of cadmium during the initial periods (30 d) but failed to produce any impact on accumulation at the end of experiment (90 d). Cadmium treatment alone did not reduce the length and weight of fish, but there was abnormality in the length weight relationship. KMnO 4 alone and in combination with cadmium significantly reduced the length, weight and yield of fish. Limnological parameters were not affected by KMnO 4 alone, but combined treatment of Cd and KMnO 4 reduced the zooplankton and phytoplankton population, primary productivity of water and NPP/CR ratio. Judicious use of KMnO 4 in aquaculture to avoid toxic interaction with cadmium has been recommended.

“…Despite the fact that [n, m]prismanes are of consider able fundamental and practical interest, no efficient procedures are still developed for their synthesis. Only "simplest" representatives of a series of [n, m]pris manes are obtained: [2,3]prismane C 6 H 6 or the Lad enburg benzene [2], [2,4]prismanes C 8 H 8 or cubane [3], and [2,5]prismanes C 10 H 10 [4]. Attempts to syn thesize [2, m]prismanes starting from [2,6]prismane C 12 H 12 failed.…”

Thermal stability of hexaprismane C12H12 and octaprismane C16H16

et al. 2015

The results of quantum mechanical calculations of elementary prismanes-hexaprismane C 12 H 12 and octaprismane C 16 H 16 -have been presented. Their stability has been investigated in terms of the density functional theory and nonorthogonal tight binding model, and the heights of potential barriers pre venting isomerization and decay have been determined. It has been established based on the analysis of the molecular dynamics data and the hypersurface of the potential energy of these metastable compounds that hexaprismane and octaprismane have a rather high kinetic stability, which indicates the possibility of the for mation of carbon polyprismanes for applications in microelectronics and nanoelectronics, power engineer ing, pharmaceutics, metrology, and information technologies.

“…10 In T-28:a there are also four vertices equivalent in T symmetry; similar connection of these vertices to a single tetravalent vertex produces again a nonplanar graph of topological T symmetry, or a C 29 H 24 hydrocarbon. Figure 7 shows the corresponding diagrams and a stereoscopic view of C 21 …”
