Jacob Schlaephor, a case study in laser innovation and the unexpected

This report aims to counter some assumptions about the nature of industrial technology by exploring the creative potential of the distance inherent in laser materials processing between designer and manufactured product.A case study of an industrially based project involving the textile company Jakob Schlaepfer, St Gallen, Switzerland, will provide the research material and underpin the report. The case study presents the development and expansion, by Schlaepfer, of self-customised laser technologies and how different laser processes have come to form an integral part of the design and production process. We aim to offer through this historical picture of Schlaepfer’s commitment to new technologies and investments that encourage innovation, two propositions that are facilitated by the distance inherent in the creative use of lasers. Firstly, that it is possible to utilise technologies normally linked with impersonalised standardisation in production, to instead create experimental products; and secondly, that technologies normally used to repeat and replicate the unexpected unique capacities of traditional making, can-be in-themselves capable of un-programmed unpredictability<br/

Evaluation of thermal soak times

A mathematical model for the heat transfer within the electronics package of a Chaparral missile was performed. The Grashof number for this configuration was less than 2000 which indicated that the primary mode of heat transfer was conduction. The Vodicka theory for heat conduction in laminated composite media was utilized to obtain the solution for the model

What is a Christian Teacher to Do with Louise Rosenblatt’s Transactional Theory of Reading?

In this theoretical analysis, the authors explore the question, What is a Christian teacher educator to do with Louise Rosenblatt’s transactional theory of reading? They begin by outlining the primary components of Rosenblatt’s transactional theory, focusing on reading as a transaction and the efferent and aesthetic stances. Next, they discuss who they are as teacher educators and former students, how their faith backgrounds intersect with Rosenblatt’s work, and the approach they took to address areas of tension that they and other Christian educators have experienced with Rosenblatt’s theory. Finally, they conclude by discussing implications of Rosenblatt’s work for reading scripture, identifying both the strengths and limitations of her theory, along with strategies for inviting students to discuss this issue at faith-based institutions

Spheromak formation and sustainment studies at the sustained spheromak physics experiment using high-speed imaging and magnetic diagnostics

A high-speed imaging system with shutter speeds as fast as 2 ns and double frame capability has been used to directly image the formation and evolution of the sustained spheromak physics experiment (SSPX) [E. B. Hooper et al., Nucl. Fusion 39, 863 (1999)]. Reproducible plasma features have been identified with this diagnostic and divided into three groups, according to the stage in the discharge at which they occur: (i) breakdown and ejection, (ii) sustainment, and (iii) decay. During the first stage, plasma descends into the flux conserver shortly after breakdown and a transient plasma column is formed. The column then rapidly bends and simultaneously becomes too dim to photograph a few microseconds after formation. It is conjectured here that this rapid bending precedes the transfer of toroidal to poloidal flux. During sustainment, a stable plasma column different from the transient one is observed. It has been possible to measure the column diameter and compare it to CORSICA [A. Tarditi et al., Contrib. Plasma Phys. 36, 132 (1996)], a magnetohydrodynamic equilibrium reconstruction code which showed good agreement with the measurements. Elongation and velocity measurements were made of cathode patterns also seen during this stage, possibly caused by pressure gradients or E×B drifts. The patterns elongate in a toroidal-only direction which depends on the magnetic-field polarity. During the decay stage the column diameter expands as the current ramps down, until it eventually dissolves into filaments. With the use of magnetic probes inserted in the gun region, an X point which moved axially depending on current level and toroidal mode number was observed in all the stages of the SSPX plasma discharge

A Probabilistic, Facility-Centric Approach to Lightning Strike Location

A new probabilistic facility-centric approach to lightning strike location has been developed. This process uses the bivariate Gaussian distribution of probability density provided by the current lightning location error ellipse for the most likely location of a lightning stroke and integrates it to determine the probability that the stroke is inside any specified radius of any location, even if that location is not centered on or even with the location error ellipse. This technique is adapted from a method of calculating the probability of debris collision~ith spacecraft. Such a technique is important in spaceport processing activities because it allows engineers to quantify the risk of induced current damage to critical electronics due to nearby lightning strokes. This technique was tested extensively and is now in use by space launch organizations at Kennedy Space Center and Cape Canaveral Air Force Station. Future applications could include forensic meteorology

Erythema Nodosum Associated With Streptococcal Infection in Pregnancy

Background: Erythema nodosum (EN) is a condition characterized by the presence of painful erythematous nodules on the pretibial aspects of the lower extremities. EN is thought to be a local inflammatory, immune-mediated reaction to a number of systemic antigenic stimuli. This condition is noted most often in women between menarche and menopause and is associated with certain drugs, infections, and pregnancy. However, no reports in the literature describe EN as a result of streptococcal infection during pregnancy

Models of Resistance: Novice Teachers Negotiating Barriers to Best Practice

The purpose of this study was to examine how graduates from three teacher education programs made decisions regarding literacy instruction and assessment as well as the extent to which they were able to implement practices learned in their education programs. Participants were interviewed and observed multiple times, and a variety of documents, such as lesson plans, assessments, and journal prompts, were collected. Data were analyzed using the constant comparative method and Bourdieu’s concepts of field, capital, and habitus. Although the participants initially accepted the existing practices of their schools, they later implemented concepts learned in their education programs. The ways in which they resisted the barriers they faced included resistance with conflict, resistance with an attitude, resistance with relationship, and resistance by making a change
