Mattis, Daniel C. | Critical curves and thermodynamic phases of lattice fluids and antiferromagnets with structured interactions | We study the classical lattice gas with hard cores, nearest-neighbor repulsive forces, and next-nearest-neighbor attractive forces. We find several thermodynamic phases (vapor, liquid, and solid) and unusually shaped critical curves, yet no critical point or triple point. We find and discuss discont... | Ising antiferromagnet; Molecular field theory | 1971-06 |

Mattis, Daniel C. | Short-range versus long-range order in a model binary alloy | We calculate the free energy of a linear binary metallic alloy using an exact transfer-matrix formalism. We obtain for the first time the electronic band structure when there is nonvanishing short-range order and calculate the temperature dependence of the short-range order parameter. Following Foo... | Binary alloys; Density of state; Free energy | 1971-07 |

Mattis, Daniel C. | Exactly solvable model of a magnetic impurity | A slight modification of the "mixing" term in Anderson's model of a magnetic impurity produces an exactly solvable model. Results of some preliminary calculations are given, and upper and lower bounds on Anderson's model are obtained by means of the exact solutions. . | Magnetic impurity; Ground-state energy; Free energy | 1971-11 |

Morrow, Carolyn | Another aspect of the fénix: Lope as writer of autos | Hispanists have frequently lamented the loss of a large number of the comedias of Lope de Vega while, proportionately, there may be greater cause for regret in the case of his autos. Texts of only forty-odd of these are known today - a number quite different from the four hundred which Juan Pérez ... | | 1972 |

Miller, Jan D. | Removal of dissolved contaminants from mine drainage | Eleven mill tailing samples from locations throughout the Rocky Mountain region were tested for their effectiveness in removal of dissolved contaminants from mine drainage . With the exception of the sample of the Blaine Mill tailing, the average capacity of the tailings tested was 9.8 mg of iron p... | Mine drainage; Mill tailing; Adsorption; Precipitation; Rocky Mountain Region | 1972 |

Archuleta, Michael | Hidden surface line drawing algorithm | This paper describes a fast procedure in processing hidden surface pictures with the output in vector form. The program has been written expressly for a Decsystem 10 and has performed successfully on three different installations. The algorithm which is being used is a modification to the Watkins' A... | Watkins algorithm; Hidden surface | 1972 |

Ailion, David Charles | New technique for determining the diffusion mechanism by NMR: application to Cl35 diffusion in TlCl | A major problem in the study of atomic motions is the determination of the dominant mechanism responsible for translational diffusion. Recently Ailion and Ho predicted that the rotating-frame spin-lattice relaxation time T l p would have an angular dependence which depends on the diffusion mechanis... | Diffusion; Solids; NMR | 1972 |

Mattis, Daniel C. | Exactly soluble model of interacting electrons | We diagonalize a many-fermion Hamiltonian consisting of terms quadratic as well as quartic in the field operators. A dual spectrum of eigenstates is an interesting result. We also derive a formula for obtaining the free energy at finite temperature. | Eigenstates; Free energy; Excitation spectrum | 1972 |

Miller, Joel Steven | Involvement of titanocene and related species in the reduction of dinitrogen and olefins | Summary Four sequential products have been spectrally detected in the reduction by sodium of dicyclopentadienyltitanium(iv) dichloride: [(77-Cp)2TiCl]2, [(77-Cp)2-Ti]1-2, [(77-Cp)(C5H4)TiH]x, and (77-Cp)(C5H4)TiH2Ti- (C5H4)(77-Cp) ("stable titanocene"); the second of these reacts rapidly and rever... | Hydrolysis; Sodium; Pressure | 1972 |

Miller, Jan D. | Hydrometallurgy | The science and technology of hydrometallurgy and chemical processing continues to advance both at the laboratory level and in plant practice. In past decades, hydrometallurgy was rather limited in scope and received relatively little attention, being largely a laboratory curiosity. But curiosity i... | Hydrometallurgy; Chemical processing; Environment; Laboratory practice; Plant practice | 1972 |

These bands appear only after the onset of viral deoxyribonucleic acid (DNA) syn... | Monkeys; Simian virus 40; Peptides; DNA, Viral/biosynthesis | 1972 |

Landesman, Bruce M. | Obligation to obey the law | It is often said that we have an obligation to obey the law just because it is the law. This idea has been espoused in the West at least as early as Socrates, and it is espoused today. It is not the special claim of any particular ideology, but has been held by advocates of most political persuasio... | Obedience; Moral; Legal | 1972 |

Firmage, Edwin B. | Knowledge and Politics by Roberto Mangabeira Unger (book review) | Unger's Knowledge and Politics is a rare philosophical endeavor: it is an expression of hope articulated as a theory of human nature and politics. The hope expressed in Unger's work is that the empiricism of Hobbes, Locke, Berkeley, and Hume, and the corollary thesis of the subjectivity of values an... | Book review; Philosophy | 1972 |
