For nanoparticles suspended in solution, thermal motion coupled with interparticle electrostatic interactions may promote particle contact, oriented alignment and hence growth.
Mentoring, professional relationship between two individuals, usually a senior and a junior employee in an organization, in which the senior employee teaches the junior employee about his job, introduces the junior employee to contacts, orients him to the industry and organization, and addresses social and personal issues that may arise on the job.
Many neurons (54.7±2.9%) continue to migrate uninterrupted after contacting perpendicularly oriented radial glial strands, whereas others turn back and reorient their migration in the opposite direction (14.7±1.7%) or pause (16.2±2.4%) after coming in contact with specific radial glial strands (Movies S3, S4, S5, S6, S7).
This is perhaps most simply due to the larger observable surface area of the body exposed to contact when oriented as such, and in itself provides a rationale for the collective alignment of band members to minimize the likelihood of an encounter and potentially cannibalistic attack from oncoming crickets.
The pinion-gear tooth surfaces are in point contact, the bearing contact is localized and oriented longitudinally, edge contact is avoided, the influence of errors of alignment on the shift of bearing contact and vibration and noise are reduced substantially.
Successful (oriented) contacts lead to rutile nucleation and rapid transformation of the joined nanoparticle pair.
A qualitative explanation for this change is given that is related to the biaxial deformation mechanism in which the disrupted contacts are predominantly oriented in the direction of the minor principle stress.
Our results indicate that permethrin-treated textiles provide minimal non-contact spatial repellency but strong contact irritancy against ticks, manifesting as a "hot-foot" effect and resulting in ticks actively dislodging from contact with vertically oriented treated textile.
However, the cells do exhibit confluence to some degree such that the dense CNF grid and randomly distributed mat seem to provide a specific contact guidance and oriented growth to the cells to result in spontaneously contracting cultures[39].
