The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...
The metal-organic–framework MOF-5 is used as an adsorbent in advanced systems for vehicular hydrogen storage that are currently under development. Presently, these systems are limited by poor thermal conductivity of the adsorption bed, and thus our research addresses how the interfaces between grains of MOF-5 can be engineered to improve...
This research was conducted in the Mamora National Forest of
Morocco to: (1) Evaluate the effect of cork oak (Quercus suber L.)
crown cover on seasonal herbage production, nutritive quality, and
foliar cover on two distinctive sites in each of two years (1982,
1983) and to (2) assess the effects...
This study looks at the properties of glycerol/citric acid as they are affected by the
length and temperature of the bake used to facilitate the condensation reaction that creates
the polymer. In particular, the length of time required for the polymer to break down in
the presence of water, both...
Studies with fluorodifen were conducted to gain more information
about its field performance and the influence of light quantity,
quality and timing of exposure on its phytotoxic properties. Uptake
and trans location in three plant species were also investigated.
These studies were aimed at evaluating the usefulness of this chemical...
The complexity of modern environmental problems has increased appeals for including scientific research and findings in natural resource policy decision making. Though scientists, resource managers, interest groups, and the general public support more science-based environmental policy, these preferences have been accompanied by growing calls for decentralization and democratization of policy...
By 2050 the world population is expected to reach 9 billion. Fears of the impact of such a large population on earth’s environmental systems and finite resources have lead efforts by governmental and non-governmental agencies to assist developing nations in reducing fertility rates to slow population growth by direct medical...
Despite their widespread use and presence at all levels of government, public commissions and boards are rarely given much attention, by the general public, academia, or surprisingly by public policy and agency experts. As a state infrastructure governing entity transportation commissions often deal with controversy, but do we really understand...
