This paper presents a reasoned account of the critiques addressed to the circular economy and circular business models. These critiques claim that the circular economy has diffused limits, unclear theoretical grounds, and that its implementation faces structural obstacles. Circular economy is based on an ideological agenda dominated by technical and economic accounts, which brings uncertain contri
En quelques années, l'économie circulaire s'est imposée de la Chine à l’Union Européenne en passant par l’Amérique Latine, comme principe clé des politiques industrielles et environnementales. Elle s’est également imposée comme principe de développement stratégique d’entreprises, villes, régions, et réseaux professionnels. On connait moins bien les critiques théoriques et pratiques dont l’économie
Природоорієнтовані рішення надають багато переваг у вирішенні низки проблем, пов’язаних зі сталим розвитком міст. Зокрема, вони допомагають обмежити вплив кліматичних змін, покращити біорізноманіття та підвищити якість навколишнього середовища, одночасно сприяючи економічній діяльності та соціальному добробуту.

With the technological advancements in electronics, thermal management is becoming a concern that considerably affects the performance of electronic parts and systems, and two-phase immersion cooling is attracting attention due to its preferable cooling capacity. In immersion cooling, heat is dissipated by boiling that occurs on hot surfaces immersed in coolants. Therefore, it is essential to inve
Doxorubicin (DOX) is a cornerstone drug in the treatment of osteosarcoma. However, achieving sufficient concentration in the tumor tissue after systemic administration with few side effects has been a challenge. Even with the most advanced nanotechnology approaches, less than 5% of the total administered drug gets delivered to the target site. Alternatives to increase the local concentration of DO
This article studies autobiographical accounts of breast cancer, so called pathographies, analysing how the body and the illness are portrayed. The article has a special focus on the experiences of the lived body, relating it to the psychological concept resilience as well as to the sense of estrangement of the body in illness and the socially situated body. The focus of the study is two autobiogr
Human overexploitation of natural resources has placed conservation and management as one of the most pressing challenges in modern societies, especially in regards to highly vulnerable marine ecosystems. In this context, cryptic species are particularly challenging to conserve because they are hard to distinguish based on morphology alone, and thus it is often unclear how many species coexist in
Retinitis Pigmentosa represents a group of genetic disorders that cause progressive vision loss via degeneration of pho8toreceptors, but there is in principle no treatment available. For any therapy development, a deeper comprehension of the dis9ease-leading mechanism(s) at the molecular level is needed. Here we focused on the cGMP-PKG system, which has been suggested10 to be a driver in several m
Laser-driven proton acceleration is a growing field of interest in the high-power laser community. One of the big challenges related to the most routinely used laser-driven ion acceleration mechanism, Target-Normal Sheath Acceleration (TNSA), is to enhance the laser-to-proton energy transfer such as to maximize the proton kinetic energy and number. A way to achieve this is using nanostructured tar
Structured solid targets are widely investigated to increase the energy absorption of high-power laser pulses so as to achieve efficient ion acceleration. Here we report the first experimental study of the maximum energy of proton beams accelerated from sub-micrometric foils perforated with holes of nanometric size. By showing the lack of energy enhancement in comparison to standard flat foils, ou
