A single mature adhesive disc of Parthenocissus tricuspidata has an average mass of only about 0.0005 g, an average attached area of about 1.22 mm2, and an adhesive force of about 13.7 N. On average, the disc can support a combined weight of stem, leaf, branchlet, and tendril which is 260 times greater than its own weight during the growth, and can sustain a maximum pulling force which is 28000...
Growth of tungsten nano-tendrils (“fuzz”) has been observed for the first time in the divertor region of a high-power density tokamak experiment. After 14 consecutive helium L-mode discharges in Alcator C-Mod, the tip of a tungsten Langmuir probe at the outer strike point was fully covered with a layer of nano-tendrils. The depth of the W fuzz layer (600 ± 150 nm) is consistent with an empirica...
comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
The caustics of Fourier integral operators are defined as caustics of the corresponding Schwartz kernels (Lagrangian distributions on X × Y). The caustic set Σ(C) of the canonical relation C is characterized as the set of points where the rank of the projection π : C → X × Y is smaller than its maximal value, dim(X × Y) − 1. We derive the L p (Y) → L q (X) estimates on Fourier integral operator...
