Calcic plagioclase (An69 Ab30), albite (An6 Ab94), and microcline (An2 Ab31 Or67) were leached over a 10-wk period at 13°C with 10−4M solutions of a number of low-molecular-weight organic acids. The effectiveness of the organic acids in dissolving the feldspars was found to be citric ≈ oxalic > salicylic > protocatech…

Six freshly enucleated, unfixed human eyes with choroidal melanomas were imaged on a 1.4-T superconducting magnetic resonance (MR) imaging system. Immediately thereafter the eyes were sectioned, and tumor samples were removed for study on a variable-field (0.19-1.4 T) nuclear MR spectroscopy unit. Shorter T1 and T2 re…

The metC gene of Escherichia coli K-12 was cloned and the nucleotide sequence of the metC gene and its flanking regions was determined. The translation initiation codon was identified by sequencing the NH2-terminal part of beta-cystathionase, the MetC gene product. The metC gene (1185 nucleotides) encodes a protein ha…

Summary Casing wear caused by new tooljoint hardfacings, such as fine-mesh tungsten-carbide hardfacing and a hardfacing covered with a layer of relatively soft material, has been investigated in the laboratory. The tests were performed on a full-scale test facility with field conditions—forces, motions, and fluids—sim…

A method to represent the effect of ionized impurity scattering in Monte Carlo calculations is presented. It is based on a model of B. K. Ridley [J. Phys. C 10, 1589 (1977)] and does not have the computational disadvantages of the Brooks–Herring and Conwell–Weisskopf models.

Abstract Sequential cation-exchange capacity (CEC) measurements were obtained from standard clays using a mechanized, variable-rate leaching device. The device consists of a motorized screwjack and as many as 24 leaching tubes coupled to 60-ml plastic syringes. Controlled withdrawal of the syringe plungers produces a…
