Measures of Durability of Resistance [PDF]
Phytopathology®, 2003 Conventional models for the durability of resistant cultivars focus on the dynamics of the frequency of resistance genes. This leads to a definition of the durability of resistance as the time from introduction of the cultivar to the time when the frequency of the virulence gene reaches a preset threshold.

Optimal Monetary Policy with Durable and Non-durable Goods [PDF]
SSRN Electronic Journal, 2002 We document that the durable goods sector is much more interest-sensitive than the non-durables sector, and then investigate the implications of these these sectoral differences for monetary policy. We formulate a two-sector general equilibrium model that is calibrated both to match the sectoral responses to a monetary policy shock derived from our ...

The Effect of Water Repellent Surface Impregnation on Durability of Cement-Based Materials
Advances in Materials Science and Engineering, 2017 In many cases, service life of reinforced concrete structures is severely limited by chloride penetration until the steel reinforcement or by carbonation of the covercrete.
