Tunnelling behaviour of the Asian subterranean termite in heterogeneous soils: presence of cues in the foraging area
(Academic Press Ltd Elsevier B.V. Ltd, 2012-05-01)
Exploitation of the environment by building a tunnel network is one of the stages involved in the foraging behaviour of subterranean termites, and it may be influenced by several factors, such as temperature, soil, drought, ...
Effect of biotic and abiotic factors on the tunneling behavior of Coptotermes gestroi and Heterotermes tenuis (Isoptera : Rhinotermitidae)
(Elsevier B.V., 2005-08-31)
Using bidimensional arenas, the construction and spatial dispersion of tunnels constructed by Coptotermes gestroi and Heterotermes tenuis (Rhinotermitidae) was determined under different laboratory conditions. Workers of ...

Quantum spin tunneling of magnetization in small ferromagnetic particles
(Elsevier B.V., 2009-04-01)
An approach is presented that can also account for the description of small ferromagnetic particle magnetization tunneling. An estimate of the saturation value of an external applied magnetic field along the easy axis is ...

Quantum description of spin tunneling in magnetic molecules
(Elsevier B.V., 2007-01-15)
Starting from a phenomenological Hamiltonian originally written in terms of angular momentum operators we derive a new quantum angle-based Hamiltonian that allows for a discussion on the quantum spin tunneling. The study ...
Tunneling among rotation tori
(Elsevier B.V., 2009-03-15)
We consider an integrable Hamiltonian system generated by the resonant normal form in order to study a particular mechanism of tunneling. We isolated near doublets of energy corresponding to rotation tori of the classical ...
Spin tunneling in magnetic molecules: Quantitative estimates for Fe8 clusters
(Elsevier B.V., 2007-12-01)
Spin tunneling in the particular case of the magnetic molecular cluster octanuclear iron(III), Fe8, is treated by an effective Hamiltonian that allows for an angle-based description of the process. The presence of an ...
