Sommario/riassunto |

Researchers share their pioneering graphical method for designing almost any distillation structure Developed by the authors in collaboration with other researchers at the Centre of Material and Process Synthesis, column profile maps (CPMs) enable chemical engineers to design almost any distillation structure using novel graphical techniques. The CPM method offers tremendous advantages over other design methods because it is generalized and not constrained to a particular piece of equipment. Understanding Distillation Using Column Profile Maps enables readers to un |

Sommario/riassunto |
|
In an age where science and technology hold sway and the humanities face a crisis, this book explores the evolving role of literature. It delves into how American self-help culture shapes contemporary ideals of success, mindfulness, and happiness, with a particular focus on its |

influence in science communication, notably in TED talks. Moreover, it underscores the enduring relevance of literature in the digital era by analyzing speculative novels that challenge established norms, including those propagated by TED. These novels include Richard Powers’ Generosity: An Enhancement, Margaret Atwood’s MaddAddam trilogy and Gary Shteyngart’s Super Sad True Love Story. They question the Western preference for visual perception, which perpetuates a human-centric worldview. By focusing on literary synesthesia in the readings, this book emphasizes sensory experiences and human-nonhuman interactions. It adopts the concept of research as assemblage and uses a diverse range of theories and approaches, while it foregrounds critical posthumanism and new materialism. Ultimately, it advocates for a less anthropocentric approach to reading and presents literature as a "transdisciplinary life science" capable of fostering a "kinship of posthumanity." |
