The strength of a chemical bond [PDF]
AbstractWe discuss the physical criteria that have been proposed as a measure of the strength of a chemical bond. Critical examination of the strengths and weaknesses of the various quantities shows that the force constant is the most general measure for determining the strength of a chemical bond in molecules.

Bond Strength of Fusion Bonded Epoxy-Coated Reinforcement in Concrete
Fusion-bonded epoxy-coated steel is expected to extend the service life of the reinforced concrete structure in chloride-laden environments. However, the effect of coating on the bond-strength between rebar and concrete is not well understood yet.

Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys [PDF]
Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating systems.

The influence of bond-rigidity and cluster diffusion on the self-diffusion of hard spheres with square-well interaction [PDF]
Hard spheres interacting through a square-well potential were simulated using two different methods: Brownian Cluster Dynamics (BCD) and Event Driven Brownian Dynamics (EDBD). The structure of the equilibrium states obtained by both methods were compared
