In this note, we show that one of the arguments used by Moazzami for computing the tenacity of the third Harary graph is wrong and then improve the proof. © 2014 Published by Elsevier B.V.

Staying attached at a favorable site can be a major challenge for organisms in flow. Meeting this challenge depends on properties of the attachment structure and substrate, the nature of fluid flow, and the ability to adjust attachment force in response to hydrodynamic conditions. A broad taxonomic range of adult stages use adhesion or suction to attach to hard substrates in intertidal habitats...

In communication networks, greater degrees of stability or less vulnerability is required. The vulnerability of communication network measures the resistance of the network to the disruption of operation after the failure of certain stations or communication links. If the network begins losing communication links or processors, then there is a loss in its effectiveness. Thus, communication netw...

Structural parameters of raw and pre-treated viscose, modal and lyocell fibres were determined using X-ray diffraction, and compared with data obtained from iodine adsorption and tenacity measurements. A good correlation was found between iodine adsorption and structural changes. These structural parameters are correlated with surface thermodynamic parameters obtained by surface tension experim...
