The formation of solution and solid complexes with heavy metals
will partially determine their mobility and plant availability in soil
systems. Experiments were initiated to determine the effect of pH,
adsorbent and initial metal concentrations, and the presence of water
soluble ligands on the adsorption of Cd and Cu by...
The adsorption of uranium ions from seawater could be of importance
as reserves of uranium are depleted. The structure, chemical
state, and concentration of uranium in seawater have been previously
determined. Uranium exists as a charged ion, UO₂(CO₃)₃⁴⁻. The concentration
in seawater is 3.3 parts per billion.
Previous studies with...
The observed and calculated structural parameters of three systems
of phosphatidylcholine bilayers in fully-hydrated multilamellar
vesicles (MLVs) were determined using x-ray diffraction techniques.
The analysis used the x-ray reflections from the low-, intermediateand
wide-angle regions of the diffraction patterns in the subgel, gel,
rippled and fluid phases to determine the...
The consistent application of phosphatase inhibitors and a novel final purification step using a connected series of DE-51, DE-52, and DE-53 anion exchange chromatography columns facilitate the preparation of electrophoretically homogeneous sub-pupulations of rabbit muscle phosphofructokinase which differ in their catalytic properties and endogenous covalent phosphate contents. A band of...
Rocks are defined as aggregates or mixtures of minerals; rocks also include noncrystalline materials such as the natural glasses, and organic material such as coal. Rocks are found ready-made in nature. They are not homogeneous nor are they crystalline, although they may be made up of crystalline material. The composition...

The strength of both undisturbed and compacted soils from 10 sites
in the slide-prone Tongass National Forest in SE Alaska were studied.
Index property tests were also conducted on disturbed samples. The
index tests included natural water content, Atterberg Limits, specific
gravity of solids, grain size distribution, and moisture-density relationship....
