276 Baehr, WolfgangIsolation and characterization of cGMP phosphodiesterase from bovine rod outer segmentsA simple purification method has been developed for isolation of bovine cGMP phosphodiesterase from photoreceptor rod outer segments. The enzyme is peripherally membrane bound in its native state and is present in relatively high concentrations. In the bovine photoreceptors its molar ratio to rhodop...Enzyme Activation; Macromolecular Substances; Trypsin/pharmacology1979
277 Capecchi, Mario R.Isolation of a suppressible nonsense mutant in mammalian cellsAn HGPRT- cell line derived from mouse L cells has been shown to have the following properties: it is CRM'; the defective HGPRT molecules are altered in the carboxyterminal peptide; the mutant cells regain HGPRT activity when ochre-suppressor tRNA is microinjected into them, but not when amber...HGPRT cell line; HGPRT activity; Ochre nonsense mutation; Mouse L cells; Mammalian cells1977
278 Miller, Joel StevenIsomeric conformations in a pentaco-ordinated ruthenium compound: crystal and molecular structures of the orange and violet isomers of (Ph3P)2[(CF3)2C2S2]Ru(CO)Summary The molecular conformations of two square pyramidal species, one violet the other orange, both composition (Ph3P)2[(CF3)2C2S2]Ru(CO) are described.Pyramidal, Radiation,1973
279 Firmage, Edwin B.J. Reuben Clark, Jr., law and international orderPresident J. Reuben Clark, Jr., spent his professional career, spanning some twenty-seven years, as an international lawyer.1 From the time of his graduation from the Columbia Law School in 1906 and his appointment as assistant Solicitor (an assistant legal adviser in the Department of State) in the...Arbitration; Settlement; Resolution1973
280 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; Philosophy1972

283 Vardeny, Zeev ValentineLattice dynamics of CuClA satisfactory fit for CuCl phonon dispersion relations is obtained for the first time. This fit is achieved by modifying the branch assignment of a few 2 phonons and by applying a double-shell model to fit the observed phonon data.CuCl; Phonon dispersion relations1975-06
284 Firmage, Edwin B.Law and the Indochina War: a retrospective viewThis century, from the Hague Conferences through the Vietnam War, has seen a profound change in attitudes toward the role of law as a constraint upon foreign policy. The Hague Conferences represented at once an attempt, however feeble, by men of mixed motives to emplace fledgling prophylactic lega...Foreign affairs; Dispute resolution; International disputes; Arbitration1974
285 Firmage, Edwin B.Law of presidential impeachmentThis Article will focus upon four influences that together determine the law of presidential impeachment: English law; the Constitutional Convention and state ratifying conventions; American impeachment experience; and public policy considerations. It is the public policy considerations upon which ...Wrongdoing; Executive branch1973

287 Herzog, OttheinLiveness of extended control structure netsA new subclass of Petri nets is defined allowing the control structure representation of parallel programs including arbitrary semaphore operations. Structural properties of the "Extended Control Structure Nets" are discussed and seven necessary and sufficient conditions for their liveness are prove...1977
288 Mattis, Daniel C.Localized magnetic moments in dilute metallic alloys: correlation effectsWe discuss qualitatively the importance of the correlation energy in determining the ground state of a metal with an impurity atom. For a single, partly occupied impurity Estate orbital, the correlation energy acts to prevent the appearance of a nonvanishing ground-state spin, so that this simple no...Magnetic moments; Metallic alloys; Correlation energy; Magnetic impurities; Orbital degeneracy1965-11
289 Ingebretsen, Robert BergstromLog spectral estimation for stationary and nonstationary processesThis research is concerned with two log spectral estimators in the context of both stationary and nonstationary signals. They differ because in one smoothing is realized before the logarithmic transformation, while the other is smoothed in the logarithimc domain. It is shown that for stationary sign...Log spectral estimation; Nonstationary processes; Log spectral estimators1975
290 Mattis, Daniel C.Long-ranged magnetic polarization effectsTwo years ago a group1 at Bell Telephone Laboratories discovered an exceedingly long-ranged magnetic interaction among rare earth (RE) atoms dissolved in palladium. It is the purpose of the present note to suggest a theory for this phenomenon, which, it will be recalled, could not be explained by t...Indirect exchange theory1964-05
291 Ailion, David CharlesLow cost high linearity solid state digital double boxcarIn this article, we describe a digital solid state double boxcar of infinite holding time and very high linearity. It uses a Hewlett-Packard (HP2212 A-M3) voltage-to-frequency converter (VFC) whose output is accumulated on a running counter, thereby providing signal averaging with an infinite holdin...High linearity; Boxcar; Instruments, Physics1969
292 Ailion, David CharlesLow cost integrated circuit versatile pulse and frequency counterIn this paper we describe a compact multipurpose counter whose design is based on the use of plastic integrated circuits. The circuit contains about $90 worth of semiconductor components and is very easy to wire; nevertheless, it is extremely versatile. It consists of dual 107 and 106 counters which...Integrated circuits; Counters; Physics instruments1969
293 Ailion, David CharlesLow-field relaxation and the study of ultraslow atomic motions by magnetic resonanceConventional resonance enables one to study motion of atoms by measurement of line width when the mean time r between jumps is less than 1/Aco, where Aa> is the rigid lattice line width, or by measurement of the spin-lattice relaxation time, Ti, when r ^ l / coo , where coo is the Larmor frequency. ...Ultraslow atomic motion; Magnetic resonance1964
294 Symko, Orest GeorgeMagnetic anisotropy of Zn-Cr alloys at very low temperaturesThe temperature dependent magnetization of Zn-Cr single crystals was measured from 2K down to 10 mK using a SQUID magnetometer. A large anisotropy is observed for the magnetization along the parallel and perpendicular axes of the crystal. For low concentrations impurity-impurity reactions do not do...Magnetic anisotropy; Zn-Cr alloys; Temperature dependent magnetization1978
295 Mattis, Daniel C.Magnetization of Ising model in nonzero magnetic fieldKnowing only the zero-field magnetization (e.g., Yang's result) of the Ising model in any number of dimensions, one can construct a lower bound on m(h), the magnetization in finite field. Knowledge of u, the internal energy per bond, enables a more efficient lower bound to be constructed. Both are ...Magnetization; Griffiths inequality1969

This model is developed around the flexible or modularly scheduled secondary school. Also included is a procedure containing a computer program, with which the adminis...Flexible scheduling; Flexibly scheduled school; Modularly scheduled school1970
299 Olson, Randall J.Mathematical description of causative factors and prevention of elevated intraocular pressure after keratoplastyIn keratoplasty with grafts the same size as the recipient bed, tight sutures and thick recipient corneal periphery distort the angle and may collapse the filtering meshwork. This can cause very high postoperative pressures, which can be avoided by the use of donor grafts larger than the recipient b...Keratoplasty; Trabecular Collapse; Angle Disrottion; Elevated Pressure; Aphakia; Mathematics1977-12
