Shapeshifting as Infrastructural Storytelling: Comics about the Taxibot’s Conflicting Narratives
Giada Peterle and Tina Harris Academy of Mobility Humanities 2024 Mobility Humanities Vol.3 No.1
What are the stories we tell about infrastructures and what stories do infrastructures tell (about) us? We propose a paper in a hybrid verbo-visual format, including comic-pages created by Giada Peterle and based on Tina Harris’s keynote at the 2022 GMHC conference, autoethnographic notes, and visuals collected during fieldwork. Through experimenting with graphic storytelling, we highlight examples of infrastructural revelation and concealment, drawing on the figure of the shapeshifter as both a metaphor and a method for mobilising infrastructural imagination. What unites shapeshifters in many of the stories and myths we read is how they are taken up in different ways; how they simultaneously present both the potential to improve human lives as well as produce fear due to their unpredictability. By focusing specifically on the narrative of one shapeshifting infrastructure—the Taxibot, a vehicle designed to cut down on carbon emissions and improve efficiency at airports—we use comics as a research practice for exploring this metaphor and developing a broader understanding of how mobile lives and imaginaries shape infrastructure (and vice versa). We argue that paying closer attention to storytelling can generate new understandings of the uneven nexus between infrastructures and mobile lives, weaving in our understanding of infrastructural im/mobilities.

Quantization effects (QEs), which manifests when the device dimensions are comparable to the de Brogile wavelength, are becoming common physical phenomena in the present micro-/nanometer technology era. While most novel devices take advantage of QEs to achieve fast switching speed, miniature size and extremely small power consumption, the mainstream CMOS devices (with the exception of EEPROMs) are generally suffering in performance from these effects. In this paper, an analytical model accounting for the QEs and polydepletion effects (PDEs) at the silicon (Si)/dielectric interface describing the capacitance-voltage (C-V) and current-voltage (I-V) characteristics of MOS devices with thin oxides is developed. It is also applicable to multi-layer gate-stack structures, since a general procedure is used for calculating the quantum inversion charge density. Using this inversion charge density, device characteristics are obtained. Also solutions for C-V can be quickly obtained without computational burden of solving over a physical grid. We conclude with comparison of the results obtained with our model and those obtained by selfconsistent solution of the Schrodinger and Poisson equations and simulations reported previously in the literature. A good agreement was observed between them.

The article considers how Korean historical drama can enrich the discourse of development and change. The study interrogates Cold War legacies in development thinking in the Philippines entrenched by US education and pop culture and contextualizes Korean drama, a representation of counter- dominant cultural flows, within cultural flows in Asia, the reception of the dramas in Asia, and patronage and influence in the Philippines. Focusing on the historical genre of Korean drama in particular, a cultural negotiation of Cold War influenced-development perspectives in the Philippines is problematized. Unpacking the complex content in Korean historical drama through intertextual analysis provokes a critical elucidation of notions of development and change and underscores interdiscursive utility for the development discourse in the Philippines.

Performances of As(III) adsorption by agglomerated nanoparticles of calcined (250℃) hydrous Fe(III)–Al(III) mixed oxide (NHIAO-250℃) were investigated at 30 8C and pH 7.0 in the absence/presence of background ions occurring in groundwater. Kinetics and equilibrium data described, respectively, the pseudo-second order and the Langmuir isotherm equations well. Higher (15–35%) monolayer capacity (58.30 ± 3.15 mg g^(-1)) of As(III) system in absence of any background ions implied the adverse influence of the incorporated ions over As(III) sorption. Increased entropy (positive ΔS) was responsible for the endothermic reactions (positive ΔH) and spontaneous nature (ΔG = negative). Thomas model described the fixed-bed breakthrough curves of As(III) removal from spiked groundwater well.
Carbon quantum dots originated from chitin nanofibers as a fluorescent chemoprobe for drug sensing

This paper reports the synthesis of carbon quantum dots (CQDs) from chitin nanofibers (CNFs) as a newcarbon source via microwave assisted-hydrothermal route within three minutes. The FL of as-preparedCQDs can be quenched after addition of Cu2+ ions. However, in the presence of D-Penicillamine (DPA), Cu2+ ions prefer to bind to DPA owing to their high affinity toward DPA and subsequently the FL of CQDs iseffectively recovered. Therefore, here for thefirst time the Cu2+ ion modified CQDs (CQDs-Cu2+) wasutilized as a FL chemoprobe for quantitative determination of DPA in biological and pharmaceuticalsamples with satisfactory results.
