The columbium-hydrogen system and hydrogen embrittlement of columbium

Columbium specimens are charged uniformly with hydrogen allowing accurate measurement of the hydrogen content by a procedure involving the removal of hydrogen from flowing argon at 2000 degrees F. Hydrogen content effects on the ductile-to-transition temperature are determined for temperatures between 200 and 600 degrees F

Identity and Witness: Liturgy and the Mission of the Church

(Excerpt) The text for this lecture is a provocative aphorism which I owe to Stanley Hauerwas. In a 1987 presentation at Trinity Seminary, he said: The church has missionary power in direct proportion to its liturgical integrity. I cite this because Liturgy and Mission are often perceived as unrelated, if not actually opposed, to each other.1 Manuals and exhortations on evangelism often do not relate the Church\u27s mission of evangelization and conversion to the administration of Holy Baptism. Programs and advice on outreach which focus on inviting persons to the Sunday gathering of the Church often do not assume that what t~kes place at the Sunday gathering is the Holy Eucharist. For many advocates of the Church\u27s mission, liturgy belongs to the task of nurture, and attention to nurture must be balanced by attention to nurture. Liturgy is thus viewed as an inward focus, and the fear is that too much attention to liturgy makes the Church narcissistic

Learning and Living Difference That Makes A Difference: Postmodern Theory & Multicultural Education

The application of postmodern theory to a transformative understanding of multiculturalism can make a difference. Multicentered culture, antiessentialist race consciousness, and political equity—aspects of a transformative multiculturalism put forward in 1996 by Newfield and Gordon—can be juxtaposed with elements of a postmodern theorization of society as a consumer-driven economy saturated with multiple mediated unstable, fragmented, and evolving discourses and cultural interaction. This theoretical construct can be illustrated with research data from college classrooms and specifically an analysis of the television show The X-Files. This analysis shows how a discussion of whiteness creates larger discussion of transformative multiculturalism in which difference makes a difference. Moreover, a postmodern transformative multiculturalism sees universities as ideological sites in the production and reproduction of hegemony

Like WheatT Arising Green: How the Church Grows and Thrives

(Excerpt) The theme for the 1991 Institute of Liturgical Studies is taken from the hymn Now the Green Blade Rises. This wonderful Easter hymn, No. 148 in The Lutheran Book of Worship, concludes each stanza with the refrain, Love is come again like wheat arising green. The resurrection of Jesus is portrayed as grain which sprouts from seed. The imagery comes from the Gospel of John, from a saying of Jesus, the whole context of which is instructive

Holy Communion Is an Artifact of the Future

(Excerpt) A bit of reminiscing seems appropriate on this anniversary occasion.2 The Institute of Liturgical Studies was founded by true pioneers in the liturgical movement. The blessings granted to that movement in terms of its achievements are awesome. I don\u27t know if anyone counted such things in the 1940s, but in the decade in which the Institute of Liturgical Studies was founded there were not a hundred congregations in all of North American Lutheranism where there was a weekly Eucharist

Noise in a Calorimeter Readout System Using Periodic Sampling

Fourier transform analysis of the calorimeter noise problem gives quantitative results on a) the time-height correlation, b) the effect of background on optimal shaping and on the ENC, c) sampling frequency requirements, and d) the relation between sampling frequency and the required quantization error

Using Lower-Division Developmental Education Students as Teaching Assistants

There has been little research on the experiences of undergraduate teaching assistants, and this small body of information is usually tightly focused on traditional disciplinary concerns like sociology, psychology, and communications. Additionally, undergraduate teaching assistant research tends to focus on upper-division students. This article explores the benefits and drawbacks of using lower-division developmental education students as teaching assistants in developmental social science courses. Included are comments from students enrolled in a course staffed by a sophomore as the teaching assistant. Employing developmental education students as teaching assistants can be beneficial to instructors, students, and the teaching assistants themselves

Using Technology to Open Storytelling Doors

In a University of Minnesota College of Liberal Arts online spotlight on teaching, I\u27m deemed to be The Open-Door Storyteller. The article notes: One of Jacobs\u27 goals is to teach his students media literacy—analyzing critically what they read, hear, and see—without reducing their enjoyment of the media. He encourages his students to learn how to tell their own stories as a way of influencing how the media in turn portrays them. Technology has been a key part of this process ever since I first stepped into the classroom as an instructor in my third year of graduate school, in 1995. I\u27ll still be using technology in the classroom when I retire, around 2035..
