Doubly charged ion mass spectra of alkyl-substituted furans and pyrroles

Doubly charged ion mass spectra of alkyl-substituted furans and pyrroles were obtained using a double-focusing magnetic mass spectrometer operated at 3.2 kV accelerating voltage. Molecular ions were the dominant species found in doubly charged spectra of lower molecular weight heterocydic compounds, whereas the spectra of the higher weight homologues were typified by abundant fragment ions from extensive decomposition. Measured doubly charged ionization and appearance energies ranged from 22.8 to 47.9 eV. Ionization energies were correlated with values calculated using self-consistent field–molecular orbital techniques. A multichannel diabatic curve-crossing model was developed to investigate the fundamental organic ion reactions responsible for development of doubly charged ion mass spectra. Probabilities for Landau–Zener type transitions between reactant and product curves were determined and used in the collision model to predict charge-transfer cross-sections, which compared favorably with experimental cross-sections obtained using time-of-flight techniques.

"Certificate respecting the Rev. John Seccombe," 1795 August

One leaf (pages 301-302) of the August, 1795 issue of Massachusetts Magazine with an editorial regarding the authorship of Father Abbey's Will. The article identifies John Seccombe as the author based on information provided by "Thaddeus Mason, Esq. of Cambridge, the only surviving classmate, and very intimate friend of the Rev. John Seccombe."

Poems copied by James Diman, ca. 1730-1733

Small pamphlet-sized notebook containing handwritten transcriptions of three poems copied by James Diman, likely in the early 1730s. The notebook contains "The Catholic Remedy. to ye Tune of To all you Ladies, not at land &c.," "Father Ab--y's Will. Col. Sweeper Camb: Dec. 1731," and "The Poet's Lamentation for ye Loss of his cat, w'ch he used to call his Muse" copied from the London Magazine, November 1733. The "Catholic Remedy" begins "You Peope who desire to mend / your Desperate Estate..." and includes the note, "Made upon A--D--'s goving over to take orders. The note refers to the voyage of Addington Davenport (Harvard AB 1719) to England join the priesthood of the Church of England in 1730. "Father Ab--y's Will" begins "To my dear Wife, / My joy and Life..." and was a humorous poem published in 1731 after the death of Harvard College Sweeper Matthew Abdy, and attributed to Jonathan Seccombe (Harvard AB 1728). The "Poet's Lamentation" begins "Oppress'd with Grief, in heavy strains I mourn..." and was written by Joseph Green (Harvard AB 1726) as a parody of a psalm composed by Mather Byles (Harvard AB 1725). Pages 10-12, holding part of "Father Ab--y's Will" are missing, and pages 13-15 are no longer attached to the item.

Conflictos entre laicos y eclesiásticos, poder y relaciones sociales en el Reino de León : Revisión crítica de un modelo

El presente trabajo realiza una revisión crítica del modelo formulado por Patrick Geary para la interpretación de los procesos conflictuales en la sociedad medieval, tomando como caso de estudio el Reino de León. A partir del análisis de los conflictos que enfrentaron al monasterio benedictino de Sahagún con los laicos en los siglos XI y XII, se examinan dos nociones que atraviesan este modelo. Por un lado, la concepción del conflicto como mecanismo de regulación de las relaciones sociales. Por otro, su carácter ahistórico, desvinculado de los procesos de cambio social dentro de los que se inscribe.
