Dynamics of Micro-Particles in Complex Environment
… micromotors (JCMs) and magnetic clusters, in complex environment are studied using numerical simulations. The self-diffusiophoresis of JCMs in a confined environment is studied first. Overall, the translocation of a JCM through a short pore is slowed down by pore walls, although the slowdown …

An empirical investigation into the use of Lean Six Sigma in a complex, resource constrained environment
… examines the use Lean Six Sigma (LSS) in a Complex Resource Constrained Environment. In particular, three distinct research topics are analysed: the impact on Stakeholder Theory and LSS when operating in an environment where customer needs are not the most salient; the impact on LSS when …

Impact of the Functional Resonance Analysis Method (FRAM) in safety management at healthcare organisations
… method is not adequate to manage safety in a complex environment. Their argument is that safety management should not solely focus on what went wrong, it should also include efforts which enable things to go right more often. If healthcare organisations want to broaden their approach towards …

Synaptic Plasticity in the Cerebral Cortex of Fragile X Knockout Mice
… cortex increases following exposure to a complex environment, but measures of synaptogenesis in Fmr1 knockout mice raised in this environment have been inconclusive. FMRP appears to be important for some, but not all forms of synaptic plasticity.

Investigating the actinomycete diversity inside the hindgut of an indigenous termite, Microhodotermes viator
… and the diversity of these bacteria within this complex environment. However, until fairly recently, most investigations of termite hindguts involved the higher termites from the Termitidae family. Little attention was paid to the lower termites, and even less to the family Hodotermitidae. The …
