Abstract： This report is about creation of information models of light quantization and absorption by an atom and/or a molecule in a language alternative to the one-electron approach. For this purpose the analysis of trigonometrical functions has been done which has revealed quantum numbers which have been applied to differentiating interpretation of the concepts quantum/photon and getting earlier unknown dependences for the terms of neutral atoms. It has enabled to enter actual multielectronic classification of atoms.

Abstract： The overwhelming interest of nanotechnology including nanoparticles, nanocrystals, nanostructure and nanoscales of all ceramic materials especially nanoceramics is one of the most exciting fields so that it incorporates materials sciences, cement, concrete and other building materials particularly bricks, ceramic wall and floor tiles and also advanced bioceramics industries. In this review article, the author wishes to indicate the importance of nanomaterials and/or nanoparticles for improving the physicochemical and mechanical properties, thermal shock, thermal expansion, firing resistance and microstructures of the resulting nanoceramic products.

Abstract： This paper presents the basic ideas and concepts for the development of information models of optical objects in the nanoscience. Quantitative ratios among regularities in trigonometric spectral analysis as a possible connection between the projection of natural (point-source) radiator and absorbing atomic section are shown. This approach has been applied to the correlation between these patterns and atomic spectroscopy (specifically, terms and ionization potentials of neutral atoms with s and p shells. This has made it possible to build information models of radiation and atomic absorption on certain principles of field continuum quantization. The paper analyzes the possibilities and limitations of the information method of calculating the singlet odd electronic states of the diatomic homonuclear molecule from their dependence on the quasi-adiabatic ionization potential and on the quantum numbers of the atoms forming the molecule.

Abstract： The culture of African catfish (Clarias gariepinus) is hamstrung by high feed cost, and efforts to reduce it have been geared toward exploiting fishmeal alternatives which are hitherto competed for by both human and livestock. There is a growing need to search for waste products which can save this situation. A 91-day feeding trial was conducted in nine tarpaulin tanks with twenty C. gariepinus fingerlings each of average weight 2.79±0.05 g to check the effect of chitosan and its nanoparticles on growth performance and feed utilization. The basal diet (BD) which served as control was formulated to contain 40％ crude protein. Two test diets were formulated to contain BD replaced with 5g kg-1 diet of chitosan (BD+CH) and chitosan nanoparticles (BD+CHN) respectively. These were replicated thrice. Chitosan supplementation was found to significantly (P<0.05) improved daily weight gain, survival and meat quality P<0.05) of C. gariepinus fingerlings while chitosan nanoparticle supplementation significantly improved water quality, daily weight gain, feed utilization, survival as well as body composition. Chitosan nanoparticles from shells of arthropods and shellfish which lay waste globally has the potentials to revolutionize aquaculture. Fish nutritionists as well as farm managers should key into this platform technology.
