Este texto questiona como Plataformas de Inteligência Artificial Generativa (IAGs) podem colaborar com a pré-visualização de cenas, parte do processo de criação de uma obra audiovisual. Para isto, ...selecionamos uma cena do roteiro do filme Titanic (1997) como fonte dos comandos para a geração de imagens. Utilizamos uma metodologia exploratória, revisamos a literatura compilando conceitos básicos sobre Inteligência Artificial Generativa, testamos as plataformas Stable Diffusion, Bing Image Creator e Genmo.AI e comparamos as imagens geradas com os segmentos do filme original e discutimos suas aproximações e diferenças. Como resultados, destacamos que as ferramentas forneceram resultados consistentes com os segmentos de roteiro, embora nem sempre alinhadas com o que o filme apresentou, o que indica um processo de tomada de decisões pelas IAGs, o que as coloca como ferramentas relevantes para a pré-visualização de um roteiro, embora não abstraiam a presença humana na criação das cenas.

•The g-C3N4-TiO2 composites were obtained by simple solid state sintering.•The composites were direct contact Z-scheme without an electron mediator.•TiO2 with large amount of SETOV ...was obtained by dehydration of NTA.
Direct contact Z-scheme g-C3N4-TiO2 nanocomposites without an electron mediator are prepared via simple annealing the mixture of bulk g-C3N4 and nanotube titanic acid (NTA) in air at 600°C for 2h. In the process of annealing, the bulk g-C3N4 transformed to ultra-thin g-C3N4 nanosheets, and NTA converted to a novel anatase TiO2, then the two components formed a close interaction. The XPS result reveals that some amount of nitrogen is doped into this novel-TiO2, and g-C3N4 nanosheets exist in the composites. The results of XRD, TEM and TG indicate that the thickness of g-C3N4 nanosheets is very thin. The ESR spectrum shows the existence of Ti3+ and single-electron-trapped oxygen vacancy in the 30%g-C3N4-TiO2 composites. In photocatalytic activity test, the 30%g-C3N4-TiO2 nanocomposites showed an excellent photo-oxidation activity of propylene under visible light irradiation (λ≥420nm), and the removal efficiency of propylene reached as high as 56.6%, and the activity kept nearly 82% after four consecutive recycles. Photoluminescence (PL) result using terephthalic acid (TA) as a probe molecule indicated that the g-C3N4-TiO2 nanocomposites displayed a Z-sheme photocatalytic reaction system and this should be the main reason for the high photocatalytic activity. A possible photocatalytic mechanism was proposed on the basis of PL result and transient photocurrent-time curves.
Over a span of forty years, James Cameron has become synonymous with the box-office blockbuster. Bigger stars, budgets, and technological innovations have led the director to transcend ...spectacle-centric contemporaries like Roland Emmerich and Michael Bay, reframing him in the words of Thomas Elsaesser, as “the embodiment of the post-auteur author” (248). For Elsaesser, the post-auteur author is distinguished in part by their ability to synergise art and business into a single entity. As is the case with Cameron, this often culminates in the formation of a production studio or visual effects company, but Cameron’s desire to create universally appealing films while exercising total control over their production seems to transcend even this tradition.
The sinking of the Titanic has captured the public imagination for over a century. A tragic tale of man's powerlessness over nature, it has served as a lesson in hubris that has been dramatized in ...film and immortalised in popular culture. Following the disaster, relatives of the deceased lodged compensation claims against the White Star Line (registered owners of the Titanic). In these compensation claims for loss of life we witness the monetary commensuration of life. For the accounting scholar, therefore, the Titanic story offers an opportunity to contribute to the growing body of research in the area of valuation; in particular, it facilitates an understanding of the valuing of human life. Drawing on the history of life assurance and compensation legislation in both the UK and US, the paper argues that by the time of the Titanic disaster in 1912, an accounting constellation (Burchell et al., 1995) had been formed which established an equivalence between the value of a life and economic earning power. However, while this earnings based model determined the value of men lost in the tragedy, it failed to commensurate the lives of women and children. Rather emotion and sentiment arising from the high profile nature of the disaster appeared to allow for a plurality of other valuations to emerge that ruptured the pre-configured constellation and challenged the linear trajectory of the economic model. As such, Titanic was a “valuation event” which severely disrupted the existing gendered assemblage. The contribution of this paper therefore is to recognise the gendered nature of valuation and to appreciate the impact of such gender bias on the practice of valuation.
During his bio-archaeological Last Mysteries of the Titanic expedition in 2005, explorer James Cameron observed the RMS Titanic's Turkish Baths, an anoxic chamber secluded from currents deep within ...the wreck's remote interior, utilizing the ROV Skipper. There, Cameron discovered anomalously thin, vertical, and bifurcating rusticle formations he termed “Rustflowers.” Proposing magnetotaxis as the involved mechanism, this study analyzed rusticles salvaged from Titanic's #8 davit bitt utilizing ferromagnetic resonance, which demonstrated an asymmetric spectrum featuring prominent uniaxial over magnetocrystalline anisotropy fields of Buni = 110 mT and Bcub = −23 mT, linewidth parameters of ΔB = 200 mT, ΔBFWHM = 144 mT, ΔBhigh = 37 mT, ΔBlow = 107 mT, and asymmetry ratio of A = 0.35, and α = 0.20. These represent the established signature of biogenic magnetofossil chains synthesized by former magnetotactic bacteria, enduring within the rusticle cortex. Electron microscopy and chemical analysis identified single-domain range magnetite nanocrystals, and crystalline elemental sulfur inclusions, respectively. Chemosynthetic microbial iron oxy-hydroxide accretions guided upward along geomagnetic field lines by north-seeking magnetotaxis, under reducing conditions exhibited in Titanic's Turkish Baths, may account for the distinctive morphology of its Rustflowers; adding dimension to the bacterial application of iron assimilated from deep-sea sources, including shipwrecks.
•The RMS Titanic's Turkish Baths are an anoxic chamber featuring remarkable preservation.•Unique rusticle formations termed “Rustflowers” grow in Titanic's Turkish Baths.•Rusticle morphology is partially influenced by magnetotaxis and surface area to volume ratios.•Iron is harvested from the Titanic by bacteria to synthesize magnetite magnetosomes.•Magnetotacitc bacteria may engage in the consortial aquatic biocorrosion of steel shipwrecks.

•An ultralow-potential H2Ti3O7·xH2O anode is first introduced for zinc-ion batteries.•The storage mechanism of H+ and Zn2+ co-insertion is demonstrated on the H2Ti3O7·xH2O anode.•The ...H2Ti3O7·xH2O anode features excellent electrochemical performance.•The assembled ZnxMnO2//H2Ti3O7·xH2O full battery exhibits the high output voltage.
Developing the alternative anode materials that can completely resolve the dendrite concern of Zn metal anodes are desirable for reliable aqueous zinc-ion batteries. However, the sub-optimal charging potentials of reported anodes inevitably cause the discounted output voltage and energy density on a zinc-ion full battery. Herein, it is firstly demonstrated that the hydrated titanic acid (H2Ti3O7·xH2O) can be applied as an ultralow-potential anode for the aqueous zinc-ion full battery. The depressed potential (0.2 V vs. Zn2+/Zn) of the H2Ti3O7·xH2O compared to that of reported candidates could significantly enhance the operating voltage level of the zinc-ion full battery. Furthermore, the comprehensive analyses demonstrate that the expanded lattice spacings and interlayer crystal water stimulate Zn2+ along with H+ to jointly insert and extract on the H2Ti3O7·xH2O anode. The low-potential H2Ti3O7·xH2O anode exhibits an impressive cycling performance and coulombic efficiency by virtue of the assistance from interlayer crystal water. The assembled ZnxMnO2//H2Ti3O7·xH2O zinc-ion full battery delivers the decent electrochemical performance, especially a high output voltage of over 1 V. This low-potential, high-stable H2Ti3O7·xH2O anode reveals the exceptional potential for aqueous zinc-ion full batteries.

In tackling chronophobia, which Svetlana Boym (2001) defines as the anxiety of deciding how to use our time meaningfully as it depletes, video games become purposeful spaces where we can revisit the ...things we have lost, or what we anticipate will be lost with time. As such, video games are ideal tools that help us retreat from chronophobia. However, following Boym, I argue that this “does not help us to deal with the future” (2001, p. 351). To revisit or experience what is already “lost” with time through games, players must lose more time and resources in the present to pursue it. This circular use of nostalgia may leave players with chronophobia and in a state of feeling “lost again.” This paper presents three case studies where nostalgic players have “found” something generative for their present and future, rather than feeling “lost again.” This original solution to chronophobia combines Boym’s work, game studies, and nostalgia research, amounting to my contribution of what I call “refractive nostalgia.”
The cleaning of traditional ceramics consumes much water and detergents. It is valuable to consider how to endow the ceramics with self-cleaning character. In this paper, titanic-based-crystallites ...(CaTi(SiO5) or TiO2) superhydrophilic glazes with superior self-cleaning properties were in situ prepared by a simple one-time firing method. There is no any extra treatment involved in the preparation process. It was found that the precipitation of titanic-based crystallites in the glaze could be adjusted by controlling the cooling system. The transformation mechanism of the phase was analyzed based on the phase separation state. Stress conditions of a dirt cell on surfaces with different roughness were discussed. The correlation between geometric structure and self-cleaning performance demonstrated that the multi-level structure is vital for self-cleaning performance. The self-cleaning mechanism of the superhydrophilic glaze was proposed. The titanic-based crystallite glazes possess superhydrophilic characteristics (<8.0 °), high hardness (642.44–707.85 kgf·mm−2), and excellent self-cleaning performance to oily ink stamps and relatively good performance to human fecal simulacrum, the miso sauce, due to the multi-level structure with nano-scale surface roughness, showing a good application potential on the self-cleaning domain, i.e. glass and traditional ceramic, etc.

•S/H2Ti6O13 composites were designed and synthesized via a simple in-situ disproportionation-assembly process.•Type-I heterojunction facilitates charge carriers' separation, extends ...light absorption, and enhances CO2 adsorption.•S/H2Ti6O13 hybrid composites exhibit markedly enhanced activity along with high stability for the production of CH4.
The photocatalytic reduction of CO2 into energy-intensive hydrocarbon fuels is promising to solve environment and energy issues. Here, elemental sulfur supported on ultrathin titanic acid nanosheets (S/HTO) heterostructure is designed and synthesized by loading different weight contents of elemental S on HTO nanosheets via a simple in-situ disproportionation-assembly process. The as-designed S/HTO heterostructure not only enhances light absorption and facilitates CO2 adsorption, but also significantly promotes the interfacial charge transport, and suppresses the recombination of photogenerated charge carriers. As a consequence, the as-prepared S/HTO heterostructure exhibits enhanced performance in photocatalytic CO2 reduction under simulated solar light illumination. A CH4 yield rate of 1.92 μmol h−1 g−1 is obtained over the optimal 15S/HTO composite without the using of cocatalyst and sacrificial agent. The photoactivity is 5.4-fold and 23-fold larger than that of HTO nanosheets and blank S, respectively. In addition, the S/HTO hybrid composite also presents high stability for the production of CH4.
