Individuals that maintain pair bonds over multiple breeding attempts are often able to improve reproductive success compared to conspecifics that switch partners. However, the behavioral mechanisms driving this ‘mate familiarity effect’ are still largely unknown. We investigated whether long-standing pairs in the long-lived, socially monogamous Steller’s jay improved their coordination of movem...

STUDY DESIGN An in vivo study on the effects of an agent for scar prevention in a dog laminectomy model. OBJECTIVE To examine the anti-adhesion properties of a thrombin-based hemostatic gelatin (FLOSEAL; Baxter International Inc., Deerfield, IL). SUMMARY OF BACKGROUND DATA Postlaminectomy dural adhesion sometimes causes symptomatic problems. Although a new type of hemostatic agent, a thromb...

A special class of cubic graphs are the cycle permutation graphs. A cycle permutation graph Pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.In this paper we determine a good upper bound for tenacity of cycle permutation graphs.

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...
