Abstract:: While the heartwood of many wood species exhibits excellent resistance to fungal and insect attack, this resistance is sometimes diminished in second-growth material of the same species. The reasons for the reduced durability are unclear, but they may reflect a combination of both higher proportions of sapwood as well as...

Equal contrast tint progressions for computer cartography

Creator:: Bernert, Joseph A.
Abstract:: A psychophysical bisectioning experiment was performed to evaluate equal steps within tint progressions on a high resolution graphics terminal. In the bisectioning experiment each respondent partitioned a tint progression by interactively defining colors that were perceptually equidistant between two previously defined colors. Twenty test subjects performed the test on the...

The effects of paralysis and oligohydramnios on morphological and behavioral characteristics of the rat fetus in utero

Creator:: Del Real, Carmen
Abstract:: Two experiments were conducted to assess the effects of paralysis and oligohydramnios on the development of the rat fetus. Behavior was suppressed in utero by subcutaneous injections of curare or puncture of the amniotic membrane leading to oligohydramnios. In Experiment 1, fetuses were treated with curare, oligohydramnios, both, or a...

Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...
