The Effect of Green Payments on the Diffusion of Conservation Technologies

The benefits from green payments for the adoption of a conservation technology or practice are reduced if the technology would have eventually been adopted regardless of the green payment. This source of additionality is likely a significant concern for some technologies subsidized by EQIP.Environmental Economics and Policy, Research and Development/Tech Change/Emerging Technologies,

Critical mass flux through short Borda type inlets of various cross sections

Mass flux measurements associated with chocked flows through four Borda type inlet geometries: circular, square, triangular and rectangular (two-dimensional) and two sharp edged geometries taken over a very wide range of inlet stagnation conditions. The measurements indicate that: (1) the mass flux is independent of the inlet cross-section geometry and (2) the mass flux is dependent only on the inlet stagnation conditions. Also by using choked flow results found in the literature, the reduced mass flux is independent of working fluid. Two implications are drawn which remain to be verified: (1) since seal leak rates are weakly dependent on geometry but pressure distribution is strongly dependent on geometry, seal design efforts should be directed more toward controlling the dynamics, and (2) high-L/D ducts of arbitrary cross section and Borda type inlets can possess free jets

Das Just Community Konzept nach Lawrence Kohlberg – von der Theorie in die Praxis :die heutige Umsetzung an deutschsprachigen Schulen

Die vorliegende Arbeit beabsichtigt, sowohl die theoretische Grundlage des Moraltheorie Kohlbergs in einer kompakten Form darzulegen, als auch zwei exemplarische Schulkonzepte vorzustellen und zu untersuchen, wie Elemente des Just Community Konzepts darin umgesetzt werden. Nach der Online-Recherche erschien es mir als besonders ergiebig, eine Primarschule in der Schweiz und eine Gemeinschaftsschule in Berlin für dieses Anliegen auszuwählen, um das Konzept Kohlbergs in seinem vollen Potenzial abbilden zu können. Trotz der theoretischen Fundierung erachte ich es zudem als relevant, das Just Community Konzept und dessen konkrete Realisierungsformen auch unter kritischen Gesichtspunkten zu betrachten, um schließlich resümieren zu können, inwieweit das in den 1960er Jahren entwickelte Konzept Kohlbergs gegenwärtig gesellschaftliche Relevanz und Umsetzungsfähigkeit besitzt

Prolonging thermal barrier coated specimen life by thermal cycle management

Measurements were made of the rate of increase in temperature of a ZrO2-8Y2O3 thermal barrier coated (TBC) specimen for various values of fuel/air (F/A) ratios when the specimen is exposed to a 0.3 Mach burner flame. For rod specimens in a carousel, the heating rates increased with (F/A) ratio and were higher at the inward facing surface for a given (F/A). Plate specimens were more sensitive to burner variations. Calculated results are given for the radial stress in the coated rod specimens for variations in (F/A) ratios from 0.04 to 0.065. Over this range, the radial stress varies from 4.3 to 5.3 MPa. The results indicate that controlling the heating rate of a TBC by controlling the (F/A) ratio offers a potential method to prolong TBC cyclic life; uncontrolled (F/A) ratios will produce scatter in experimental results. Geometric arrangement can have an equivalent effect, but is usually fixed by design

A Derridarean critique of Logocentrism as opposed to Textcentrism in John 1v1

In Kelber’s hermeneutics of John, the notion of the pre-existence Logos is central. The Logos, in his reading, is prior to the realm of history and outside the reality of the narrative text. I have argued that the Logos in John can be seen as a leading case of logocentrism as coined by Derrida. The term ‘logocentrism’ refers to the Graeco-Christian or Johannine Platonic tradition according to which written language belongs to the realm of the imperfect whereas true knowledge pertains to the pre-existent, personified Logos. Derrida provides an uncompromising critique of logocentrism. He read Western theology and philosophy not in terms of a fading logocentrism and a rise of textcentrism, but rather in terms of the illusion of logocentrism. Derrida’s principle of distress is the referential paradigm of language. The linguistic sign is defined by the signifier and the signified. The signifier constitutes the visible marks committed to paper and the signified is the so-called meaning we attached to them. For Derrida, written language is generally seen as inferior whereas spoken language takes on transcendental significance and an ontological status to the referent of language. The Western tradition of philosophy and theology views writing as exterior whereas speech appears as innocent. Derrida’s logocentrism approach challenges the privileging of speech over writing in the referential system, accusing Western theology and philosophy of falsely enslaving the sign by establishing a transcendental signifier over against writing. In this article, these ideas of Derrida are applied by reading the Logos in the Johannine narrative from the perspective of orality and textuality

The dryout region in frictionally heated sliding contacts

Some conditions under which boiling and two-phase flow can occur in or near a wet sliding contact are determined and illustrated. The experimental apparatus consisted of a tool pressed against an instrumented slider plate and motion picture sequences at 4000 frames/sec. The temperature and photographic data demonstrated surface conditions of boiling, drying, trapped gas evolution (solutions), and volatility of fluid mixture components. The theoretical modeling and analysis are in reasonable agreement with experimental data
