Scene classification is a popular research topic in computer vision, and has received much attention in the recent past. Conventionally, scene classes are considered to be mutually exclusive. However, in real-world scenarios a scene image may belong to multiple classes, depending upon different perceptions of the masses. In this paper, we propose an improved Bandler and Kohout’s sub-triangle pr...

Flooding of gas diffusion electrodes (GDEs) used in electrochemical conversion CO2 to ethylene is caused by polymerization minor products. The polymer so created reduces the hydrophobicity GDE, leading initially a reduction yield and finally complete failure.

A combinatorial proof of the Gaussian product inequality (GPI) is given under assumption that each component a centered random vector $\boldsymbol{X} = (X_1, \ldots, X_d)$ arbitrary length can be written as linear combination, with coefficients identical sign, components standard vector. This condition on $\boldsymbol{X}$ shown to strictly weaker than density $(|X_1|, |X_d|)$ multivariate total...

   Graphene oxide (GO) was prepared by an improved green chemical method using graphite flakes, KMnO4, a mixture of H2SO4/H3PO4, H2O2 and HCl. In several stages, ultrasound was used to separate the oxidized layers of GO. The use of ultrasound optimizes the effect of the reacting agents, decreasing the required amou...

A green, efficient, chemoselective, facile and clean procedure is described and discussed for the synthesis of α, α'-bis (substituted-benzylidene) cycloalkanones in solvent-free conditions. The condensation reaction was carried out through the reaction of aromatic aldehydes with cycloalkanones in the presence of Fe3O4@WO3 (Fe3O4@WO3</s...

The electrochemical reduction of carbon dioxide (CO 2 ) constitutes an increasingly important scientific topic and research on novel electrocatalysts for this demanding reaction is constantly increasing. One the most properties to be inferred such their product selectivity potential dependence thereof. However, wide range materials currently employed in CO electroreduction (e.g., Ag, Cu, Pd) en...

A new category of hybrid organic-inorganic zirconium phosphonate, Zr[(O3PCH2)2NC6H4CO2H].2H2O was synthesized and the applicability of the prepared sorbent as an ion-exchanger for removal of Ni2+, Cu2+ and Zn2+ from aqueous solutions was evaluated. The characterization of the synthe...
