Insect antenna is a multisensory organ, each modality of which can be modulated by biogenic amines. Octopamine (OA) and its metabolic precursor tyramine (TA) affect activity of antennal olfactory receptor neurons. There is some evidence that dopamine (DA) modulates gustatory neurons. Serotonin can serve as a neurotransmitter in some afferent mechanosensory neurons and both as a neurotransmitter...

New technological and scientific advances in the development of sensors actuators demand new devices to deal with recent problems challenges these emerging processes. Moreover, paper-based have tremendous potential for developing as paper exhibits capillary transport hygroexpansion due swelling fibers when absorbing water. Therefore, this proposes a mini actuator that is based on hygro-thermal-...

Humidity responsive materials are increasingly attracting significant interest for soft robotics and deployable structures. Their shape-changing behavior is based on differential hygroscopic characteristics of the single components their microscopic architecture. Although existing moisture-induced achieve morphing in various humidity conditions, practical operational environments involve presen...

A mathematical model allowing coupled hygro-thermo-mechanical analysis of spalling in concrete walls at high temperatures by means of the moving boundary problem is presented. A simplified mechanical approach to account for effects of thermal stresses and pore pressure build-up on spalling is incorporated into the model. The numerical algorithm based on finite element discretization in space an...
