Due to high surface-to-volume ratio of nanoscale structures, surface stress effects have a significant influence on their behavior. In this paper, a two-dimensional problem for an elastic layer that is bonded to a rigid substrate and subjected to an inclined concentrated line load acting on the surface of the layer is investigated based on Gurtin-Murdoch continuum model to consider surface stre...

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...
