Although hemiparasitic plants have a number of roles in shaping the structure and composition of plant communities, the impact of this group on ecosystem processes, such as decomposition and nutrient cycling, has been ...

In recent years rural issues have forced themselves to the forefront of the political agenda in countries across the developed world. Agricultural reform and income levels, the legality of hunting and field sports, housing ...

ViSIAr (Virtual Sensor Integration Architecture) is an idealised framework for building sensing subsystems of flexible assembly and other robotic systems. This paper considers how it supports the design and analysis phase, ...

Employing a polyatomic version of the basin hopping global optimization algorithm, together with interatomic potentials specifically tailored to accurately describe the structures and energetics of nanoscale silica, a large ...

Defect-free fully coordinated (FC) structures are well known to be highly stable for a number of materials exhibiting three-coordinated bonding at the nanoscale (e.g., C60) . For topologically more complex nanosystems with ...

This article evaluates features of leaf and ¯ower senescence that are shared with, or are different from, those of other terminal events in plant development. Alterations of plastid structure and function in senescence are ...

We investigate the effects of the contact angle θw, and the angle of inclination θ on the interaction between an infinite cylinder and a free fluid-fluid interface governed only by its surface tension. We describe a numerical ...
