    Despite the large number of metal–organic frameworks that have been studied in the context of post-combustion carbon capture, adsorption equilibria of gas mixtures including CO₂, N₂, and H₂O, which are the three biggest components of the flue gas emanating from a coal- or natural gas-fired power plant, have never been reported. Here, we disclose the design and validation of a high-throughput multicomponent adsorption instrument that can measure equilibrium adsorption isotherms for mixtures of gases at conditions that are representative of an actual flue gas from a power plant. This instrument is used to study 15 different metal–organic frameworks, zeolites, mesoporous silicas, and activated carbons representative of the broad range of solid adsorbents that have received attention for CO₂ capture. While the multicomponent results presented in this work provide many interesting fundamental insights, only adsorbents functionalized with alkylamines are shown to have any significant CO₂ capacity in the presence of N₂ and H₂O at equilibrium partial pressures similar to those expected in a carbon capture process. Most significantly, the amine-appended metal organic framework mmen-Mg₂(dobpdc) (mmen = N,N′-dimethylethylenediamine, dobpdc ⁴⁻ = 4,4′-dioxido-3,3′-biphenyldicarboxylate) exhibits a record CO₂ capacity of 4.2 ± 0.2 mmol/g (16 wt %) at 0.1 bar and 40 °C in the presence of a high partial pressure of H₂O.Jarad A.

    abstract: This document is a compendium of the materials that are housed within the special collections donated by Thomas Everett. In August 2016, the Arizona State University School of Music, through the efforts of retired Professor of Trombone Douglas Yeo, received a donation of materials from Thomas Everett, founder of the International Trombone Association and retired director of bands at Harvard University. This donation contains published and unpublished music, numerous letters, and various drafts of his book, An Annotated Guide to Bass Trombone Literature. Over the course of two-and-a-half years, the donation was catalogued for the university by the author. Materials from the donation were sent into public circulation or sent into special collections within the ASU School of Music Library.Dissertation/ThesisDoctoral Dissertation Music 201

    Test re-test reliability of an employment outcomes instrument (EOI)

    Plan BPersons with disabilities are one of societies most disadvantaged groups. They experience unfair discrimination and prejudice and are subject to unemployment and poverty. Of working age persons with disabilities, only 27.8 percent are employed, (McNeil, 1993) and approximately 30 percent are living in poverty (Kaye, 1998). The goal of community rehabilitation programs (CRPs) is to provide services to assist individuals with disabilities obtain employment with good pay, benefits, and job satisfaction. While CRPs all work toward a common goal, each program may use different interventions and have varying rates of success in assisting individuals with disabilities to obtain gainful employment. The rates of success of persons served by CRPs are unknown due to a lack of standardized methodology for collecting and reporting these outcomes (McAlees, Menz, & Center Staff, 1998). Therefore, a need exists to develop a standardized method of collecting and reporting employment outcomes of persons served by CRP's. The purpose of this study was to conduct a preliminary analysis of data collected in previous research completed by the Research and Training Center (RTC), University of Wisconsin-Stout and to examine the reliability of items included in the experimental version of the Employment Outcomes Instrument (EOI). The sample used in this study included 5 community-based rehabilitation programs that are certified by the Commission on the Accreditation of Rehabilitation Facilities (CARF) in vocational rehabilitation services leading to community-based employment. Subjects included 51 consumers who were chosen based on having participated in a rehabilitation program and securing community based employment in the previous 3-6 month period. The EOI was developed by Thomas, Menz, and Radtke (1999) of the Research and Training Center at the University of Wisconsin-Stout. The instrument includes questions regarding employment planning and preparation, consumer goals prior to entry in the CRP, employment achieved, work related benefits, satisfaction with services, goals achieved, and benefits lost. The results of the study indicated that the majority of the questions (.70) asked on the EOI elicited consistent responses during the two interviews. Findings will be used to refine the instrument before using it in future outcome studies

    Christiformitas in Nicholas of Cusa’s Roman Sermons (1459)

    No full text
    Nicholas of Cusa (1401-1464) served as vicar of Rome in the absence of Pope Pius II at the Congress of Mantua (1459). Cusanus held a synod and did visitations of major churches. His sermons for these events emphasized conformity with Christ as the means of knowing God.This is the Version of Record (VoR) of the article that was originally published in Perspectives in the Arts and Humanities Asia, Volume 1, Number 1 (2011

    The Gospel of Thomas and the earliest texts of the synoptic gospels

    No full text
    Research on the Gospel of Thomas in the last quarter of a century has made it clear that the origins of this apocryphal gospel cannot be satisfactorily explained from a single point of view. The author thus suggests that Thomas be understood as a growing collection of sayings which originated in various places and languages, with some logia being added to the collection after its inception. While this suggestion is by no means new, there have been few extensive attempts to study Thomas from such a presupposition. Due to the need for a control group, only the logia which have rather close parallels to the Synoptic gospels are investigated. Verbal and textual affinities are noted between these logia and the earliest texts of the Gospels (the Coptic versions, the Diatessaron, the Old Syriac version, and other early versions and Christian writings). Various degrees of probable contact between each logion and these texts are assigned. The results of this study give some idea as to the place of origin, the original language, and the approximate date at which certain logia were added to the collection. Those sayings which show a closer affinity to the Diatessaron, the Old Syriac version, or other Syrian writings may be considered as having been added to the sayings collection as it circulated in its earliest form, possibly in a Semitic language. Other logia which show no signs of awareness of a Syrian reading, but which are similar to variants found in the Coptic versions or other Egyptian texts, may well have originated in Egypt and been added to the collection at a later stage. These results, however, must await verification by those who might approach Thomas from related, but different, perspectives
