Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Global burn-out

2013
Il fallait établir ce constat : avant d'être un problème individuel, le burn-out est d'abord une pathologie de civilisation. Marquée par l'accélération du temps, la soif de rentabilité, les tensions entre le dispositif technique et des humains déboussolés, la postmodernité est devenue un piège pour certaines personnes trop dévouées à un système dont ...

Burn-out, of …?

Tijdschrift voor Bedrijfs- en Verzekeringsgeneeskunde, 2006
Bart is bouwkundige te Zaandam op een middelgroot architectenkantoor.Hij werkt daar al 8 jaar met plezier, en tot volle tevredenheid van zijn klanten en collega’s. Maar het laatste jaar gaat het minder. Hij maakt steeds vaker grote fouten in zijn berekeningen, en dat heeft het kantoor al aardig wat geld gekost. Hij wordt ook steeds somberder en trager.
