Article on ₁¹H+ and ₂⁴He+ -induced M-shell x-ray-production cross sections for selected elements in the rare-earth region.

This report describes archaeological testing at a site known as Fort St. Leon in Louisiana. Studies were made of levee building, geomorphology, and comparison of archival maps and aerial photographs, which contribute to the understanding of human activity as well as geological processes at the site.

This article provides comments on "Generalized corresponding-states method for the prediction of surface tension of pure liquids and liquid mixtures," published in the 'Journal of Colloid and Interface Science' in 1982.

This article discusses direct ionization and electron capture in M-shell x-ray production by fluorine ions.

Article on isentropic compressibility of an ideal ternary solution.

This pamphlet discusses merit pay for teachers. In most societies, the acquisition of money is a symbol of success. The present supply as well as the quality of public school teachers in the United States is directly related to the salaries that are paid to teachers as compensation for services rendered. How much to pay teachers for their services, who should be given merit pay, and how a pay plan should be administered are the focal points of an issue that promises to promote debate in the forthcoming presidential election.

Article on solubility in binary solvent systems III and predictive expressions based on molecular surface areas.

Article on the thermochemical excess properties of multicomponent systems and representation and estimation from binary mixing data.

Article on thermochemical investigations of associated solutions and the calculation of solute-solvent equilibrium constants from solubility measurements.

Article on thermochemical investigations of nearly ideal binary solvents and the solubilities of iodine and benzil in systems of nonspecific interactions.
