The effect of rootstock on the nectar production of apple cultivar `Idared'

open access: yesInternational Journal of Horticultural Science, 2001
Approaches based on the daily rhythm of apple flowers provide a new stage in nectar research, where the synchronous functioning of sexual organs is studied. In the flower biological studies the insect attraction of flowers was also studied.

Janus on the mudflats [PDF]

open access: yesBritish Journal of Ophthalmology, 2003
An amphibious fish, Periophthalmus argentilineatus is a mudskipper that spends most of its time on the mudflats of the tropical mangrove swamps of Africa, Asia, and Polynesia. It uses its stiff fins like walking sticks to perambulate with surprising speed and agility in the intertidal zone, seeking insects and small aquatic organisms.

Discrete optimal weight design of geometrically nonlinear truss-structures

open access: yesComputer Assisted Methods in Engineering and Science, 2023
In this paper, we introduce a new branch-and-bound type method, for discrete minimal weight design of geometrically nonlinear truss structure subject to constraints on member stresses and nodal displacements when the member cross-sectional areas are ...
