Why is economics so fragile? by José Castro Caldas, Vítor Neves, José Reis

“…We then question whether the public and the media might be justified in attributing the blame for the economic crisis to the particular type of economics taken as representative of the profession and of academia. Finally we address the prospect of a (more) robust and prudent economics, which would have to be anchored in a solid understanding of institutions, institutional configurations, and their variety and dynamics.…”

Jean-Clet Martin, Logique de la science-fiction : de Hegel à Philip K. Dick (2017) by Jean-Loup Héraud

“…If science-fiction explores the literary creation of imaginary worlds contradicting the familiar logic of our world, the hegelian logic explores the steps of the deep reality of « Being », « Essence » and finally the « Concept ». The endless travels of space conquest opening The Cycle of Foundations (Asimov) becomes the metaphor of travel in the spirit through the dialectical moments of Being : this adventure recap a knowledge that exceedsthe limits of our own world. …”

The role of circular shield in improving the thermal efficiency of domestic gas stove by Mingze Su, Yu Lin, Deqi Meng, Naiping Gao, Tong Zhu, Jiawei Chen, Dingrui Zhang, Zhonghua Li, Xiaowen Liu

“…By means of the thermodynamic analysis, the main role of circular shield in improving the thermal efficiency of domestic gas stove was finally elucidated. The role can be expressed as: the circular shield establishes a radiation heat transfer pathway from the circular shield to the bottom wall of the pot, and through this pathway, the circular shield transfers heat absorbed from the flue gas to the bottom wall of the pot. …”
