“Since we are diurnal, colour-vision mammals, the photographs we chose tend to depict species that are brightly coloured”, they write. “As a result, the particular ledger of species we chose is biased in favour of those that warn potential predators to stay away, and their mimics.” But the authors point out that so little work has been done on these species that it is hard to know which are gen...

With the aim of assessing the impact of sand mining project environmental Lo River, subjects used the method of sediment transport modeling in rivers, using Sand Transport module in the hydrodynamic model Mike 21 for a particular project. The result was to determine the feasibility of a sand mining project on the Lo river. The subject has shown that the effects of sand mining project on the flo...

Analysis of strain and the study of flexural moments of a deformed object is of utmost importance in non-destructive testing and evaluation. In digital holographic interferometry (DHI), this information is provided, respectively, by the first and second-order derivatives of the interference phase. This paper introduces high-order instantaneous moments based approach for the simultaneous measure...

We report first principles density functional calculations for 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and several reduced forms. DHICA and 5,6-dihydroxyindole (DHI) are believed to be the basic building blocks of the eumelanins. Our results show that carboxylation has a significant effect on the physical properties of the molecules. In particular, the relative stabilities and the HOMOLUM...
