Many animal species divide space into a patchwork of home ranges, yet there is little consensus on the mechanisms individuals use to maintain fidelity to particular locations. Theory suggests that animal movement could be based upon simple behavioural ru
Flow diagram of study progress in the 5.0 mm-BOZD OK, 6.2 mm-BOZD OK, DISC and SCL groups. BOZD, back optic zone diameter; OK, orthokeratology; DISC, defocus incorporated soft contact; SCL, soft contact lens Full size image Table 2 Baseline information for participants in four groups Ful...
The emission current was 100 µA and the test voltage was 1.4 kV. 3 GC-MS Analysis on Volatile Constituents Automatic retrieval on mass spectral data of each constituent from the Xcalibur Library Browser showed the similarity was more than 800 and further checked and confirmed with the ...
Therefore, the objective of this work is to better understand how the established (thermally and hydrodynamically) movement in a perpendicular square duct interacts with the MF formed by neighboring current-carrying wires. A constant pressure gradient drives the flow under the condition of uniform ...
This work paves the way towards the development of next-generation nanofluidic catalytic membranes, which can overcome the membrane permeability-selectivity trade-off of the current water filtration and purification technologies. Methods Preparation of monolayer VMT nanosheets An ion-exchange method was ...
Reliable and comprehensive predictive tools for the frictional pressure drop (FPD) are of particular importance for systems involving two-phase flow condensation. However, the available models are only applicable to specific operating conditions and chan
