Princess and the Pea at the nanoscale: Wrinkling and delamination of graphene on nanoparticles [PDF]

open access: yes, 2012
Thin membranes exhibit complex responses to external forces or geometrical constraints. A familiar example is the wrinkling, exhibited by human skin, plant leaves, and fabrics, resulting from the relative ease of bending versus stretching. Here, we study

Planting density and selection method in rice plant

open access: yesJapanese Journal of Breeding, 1963
1. An investigation was made on the interaction between genotype and planting density in rice -plant, with the aim of contributing to the breeding of varieties adapted to high planting density. 2. The experiment consisted of two different forms of culture, i. e., early season culture and ordinary season culture.
