This paper presents a simulation method to determine the local sensitivity of geometrical parameters of the micro-beam models used in the micro-mechanical structures. The analysis allows for defining the essential parameters in designing the microstructures to reduce the designing time. The analysis results can be used to give suitable geometrical parameters for the micro-mechanical structure according to the purposed resonant frequency.

The kinetic study was also carried out by studying the adsorption process at different temperatures using these two adsorbents to find the rate of adsorption process, its mechanism and to determine different thermodynamic parameters. For this purpose, different kinetic models were used which include film diffusion, particle diffusion, intraparticle diffusion, Elovich, Lagergren pseudo first order, Lagergren pseudo second order, simple first order and second order equations.

This study uses chitin as a filler for a polyurethane composite foam. The obtained polymer composite materials (PCM) are examined the technological parameters of the foaming (start time, rise time, and apparent density), the physical-mechanical properties (the compressive stress, compression set, resilience), and the cross-link density.

In this paper, we considered the propagation wave in transversely isotropic piezoelastic medium based on the nonlocal strain gradient theory. Two kinds of scale parameters, namely, the nonlocal parameter and the strain gradient parameter are introduced to account for the size effect of mechanical properties of nanostructures.

In ebook "Plant-environment interactions: From sensory plant biology to active plant behavior" documents a paradigm shift that is currently underway in the plant sciences. In the last two or three decades, plants have been unmasked as being very sensitive organisms that monitor and integrate large numbers of abiotic and biotic parameters from their environment. The obvious conservation that occurs throughout evolution means that action potentials provide both plants and animals with evolutionary advantages that are crucial to their adaptive behavior and survival.
