A pore-array intensified tube-in-tube microchannel (PA-TMC), which is characterized by high throughput and low pressure drop, was developed as a gas–liquid contactor. The sulfite oxidation method was used to determine the oxygen efficiency (φ) and volumetric mass transfer coefficient (kLa) of PA-TMC, and the mass transfer amount per unit energy (ε) was calculated by using the pressure drop. The effects of structural and operating parameters were investigated systematically, and the two-phase flow behavior was monitored by using a charge-coupled device imaging system. The results indicated that the gas absorption efficiency and mass transfer performance of the PA-TMC were improved with increasing pore number, flow rate, and number of helical coil turns and decreasing pore size, row number, annular size, annular length, and surface tension. The φ, ε and kLa of PA-TMC could reach 31.3%, 1.73 × 10−4 mol/J, and 7.0 s−1, respectively. The Sherwood number was correlated with the investigated parameters to guide the design of PA-TMC in gas absorption and mass transfer processes.
The study focuses on the necessity of an anthropomorphic approach in deconstructing the symbolic understandings of animals in children’s literature, and considers how such an approach can be used to draw ethical attention to the unnatural history of animals in the Anthropocene. The paper analyses three children’s novels that depict animals without representing their subjectivity in characteristically human terms. These novels are Eva Hornung’s ferality tale Dog Boy (2009), Sonya Hartnett’s fable The Midnight Zoo (2011) and Kate Applegate’s animal autobiography The One and Only Ivan (2012). Informed by Jacques Derrida’s anti-anthropocentric views and the ethical discourse of creaturely vulnerability, this essay argues that the world’s present state of cascading environmental impoverishment demands an anthropomorphic approach that is not inherently anthropocentric, along with an emerging kind of creaturely consciousness.
