The supported ionic liquid phase (SILP) concept, which included thin films of dispersed onto porous support surfaces, was applied for the gas-phase hydroformylation but-1-ene catalyzed by Rh-bpp (bpp=biphephos ligand) complexes. material silica carefully pre-treated a hydrothermal procedure to induce textural changes concerning pore size. Starting with mean size 3 nm these could be enlarged alm...

background: availability of antiretroviral therapies has transformed aids into a manageable chronic condition and im­proved well-being among people living with hiv/aids (pha) in developed countries. in developing countries however, such transformations are yet to occur due to socio-economic, systemic and environmental constraint. this study examined the impact of social, economic, psychological...

This research aims at proposing a new method for discovering frequent temporal itemsets in continuous subsets of a dataset with quantitative transactions. It is important to note that although these temporal itemsets may have relatively high textit{support} or occurrence within particular time intervals, they do not necessarily get similar textit{support} across the whole dataset, which makes i...

V2O5/SiO2 catalyst was utilized to oxidize SO2 to SO3 species in the presence of oxygen mainly for producing sulfuric acid. For this catalyst, the active phase was a mixture of vanadium pentoxide and basic sulfate/pyrosulfate material. This active phase at the reaction temperature behaved as a liquid filling up the pores of the silica support. On the other hand, amounts of the SO3 and V5+ speci...
