Diameter effect on stress-wave evaluation of modulus of elasticity of logs

Recent studies on nondestructive evaluation (NDE) of logs have shown that a longitudinal stress-wave method can be used to nondestructively evaluate the modulus of elasticity (MOE) of logs. A strong relationship has been found between stress-wave MOE and static MOE of logs, but a significant deviation was observed between stress-wave and static values. The objective of...

Differences in molecular characteristics between Cronartium quercuum from Japan and fusiform rust from USA

The molecular characteristics were compared among Cronartium quercuum f. sp. densiflorae and C. quercuum f. sp. thunbergii from Japan and C. quercuum f. sp. fusiforme, fusiform rust from the USA. The authors examined the PCR-amplified internal transcribed...

Biological and Management Implications of Fire-Pathogen Interactions in the Giant Sequoia Ecosystem

An overriding management goal for national parks is the maintenance or, where necessary, the restoration of natural ecological processes. In Sequoia-Kings Canyon and Yosemite National Parks, there is concern about the effects of fire suppression on the giant sequoia-mixed conifer forest ecosystem. The National Park Service is currently using prescribed fire management...
