Članek najprej navaja pomene in pozitivne učinke branja: boljše razumevanje lastne izkušnje, razvoj jezikovnih zmožnosti itd. Nadalje se osredotoča na trivialno literaturo: najprej jo definira, nato ...povzame statistične podatke o izposoji lete v slovenskih knjižnicah v poletnih mesecih v letu 2010. Opiše tudi kvarne učinke branja tovrstnega leposlovja, še posebej na otroke, ki jih avtorica opaža tudi pri svojih dijakih: lažne (stereotipne) predstave o svetu, manjše zmožnosti kritičnega mišljenja in slabše poznavanje jezikovnih sredstev, vpliv na podzavest in zgledovanje po neprimernih literarnih junakih. Nadalje avtorica špekulira o možnih vzrokih za tovrstno izbiro branja.
Both Jeanette Winterson and Muriel Spark try to challenge and overcome culturally constructed binary oppositions between two genders. Winterson imposes femininity on men and masculinity on women. She ...denies traditional gender roles. In her novels, men and heterosexuality are marginalized or even overlooked. Both Winterson and Spark portray women, who are active, independent and domineering; they reject marriage, are educated, live on their own and are in control of their lives. The main difference between Winterson’s and Spark’s women is that the former are heroines and the latter are victims (either of themselves or the others).Both authors deny traditional notion of time and history. Winterson useshistory to explore the present. She magnifies the individual’s role in history-making and challenges the traditional notion of history being male-constructed. She gives a woman a role in history-making. Both Spark’s and Winetrson’s novels are set anti-linearly with the use of prolepses and antilepses.
In this study, titanium dioxide nanotubes were prepared by electrochemical anodization technique and modified with an aqueous solution of FeCl3 using hydrothermal synthesis method to control the ...amount and distribution of iron compounds on the anatase TiO2 nanotubes. The objective was to synthesize immobilized FeOOH@TiO2 or Fe2O3@TiO2 photocatalysts designed for the flow-through reactor systems; to investigate thermal treatment effect on the photocatalytic efficiency; to determine appropriate Fe-compounds concentration for the maximum photocatalytic activity improvement, and to explain the mechanism responsible for the enhancement. The photocatalysts were tested for the degradation of 1H-benzotriazole in water under UV/solar light irradiation. Up to two times increase in the photocatalytic activity was obtained when TiO2 nanotubes were modified with 0.8 mM Fe. At higher Fe concentrations (8 mM and 80 mM), the photocatalytic activity of the given photocatalysts decreased. To confirm the formation of FeOOH or Fe2O3 species, and to clarify the mechanism of photoactivity, X-ray diffraction (XRD), Raman spectroscopy (RS), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray spectroscopy (EDS) and UV-Vis spectroscopy were used.
Cu-modified immobilized nanoporous TiO2 photocatalysts, prepared by electrochemical anodization of titanium foils, were obtained via four different synthesis methods: hydrothermal synthesis, ...anodization with Cu source, electrodeposition, and spin-coating, using two different copper sources, Cu(NO3)2 and Cu(acac)2. The objective of this research was to investigate how copper modifications can improve the photocatalytic activity of immobilized nanoporous TiO2 under the UV/solar light irradiation. The best photocatalytic performances were obtained for Cu-modifications using spin-coating. Therefore, the effect of irradiated catalyst surface areas on the adsorption of model pollutants, methylene blue (MB) and 1H-benzotriazole (BT), was examined for samples with Cu-modification by the spin-coating technique. The mechanisms responsible for increased degradation of MB and BT at high Cu concentrations (0.25 M and 0.5 M) and decreased degradation at low Cu loadings (0.0625 M and 0.125 M) were explained. 1H-benzotriazole was used to study the photocatalytic activity of the given samples because it is highly toxic and present in most water systems. The characterization of the synthesized Cu-modified photocatalysts in terms of phase composition, crystal structure, and morphology were investigated using X-ray Diffraction, Raman Spectroscopy, Scanning Electron Microscopy, and Energy Dispersive X-ray spectroscopy.
