Durability testing at one atmosphere of advanced catalysts and catalyst supports for automotive gas turbine engine combustors, part 1

The durability of catalysts and catalyst supports in a combustion environment was experimentally demonstrated. A test of 1000 hours duration was completed with two catalysts, using diesel fuel and operating at catalytically supported thermal combustion conditions. The performance of the catalysts was determined by monitoring emissions throughout the test, and by examining the physical condition of the catalyst core at the conclusion of the test. The test catalysts proved to be capable of low emissions operation after 1000 hours diesel aging, with no apparent physical degradation of the catalyst support

After the education disciplines: teaching theory on-line.

Like all social theorising, the academic study of education is 'reflexive'- complicated by the fact of our immersion in it. This paper discusses an on-line version of an undergraduate teacher-education course, 'Social Issues in New Zealand Education,' that is designed to teach its students how to do such 'situated' educational theorising. Consistent with this theme, the paper is written as a stream-of-consciousness narrative. In an attempt to fix in print the 'counterpoint' of pedagicical theorising in general, as well as more specifically in an on-line setting, it is episodic in structure - more like the lateral leaps of hypertext than the disciplined hierarchies of headings characteristic of the linearity of conventional academic argument. It falls into three parts. The first introduces the online virtual classroom environment in which the teaching takes place. Part two locates the course within more general epistemological issues confronting designers of education (foundations) courses in pre-service teaching degrees in the twenty-first century. In Part three, the syllabus of the course is outlined. The paper concludes with examples of students doing 'situated' educational theorising as they engage with course readings and assignments. Through this multi-layered account, I raise for discussion some broad questions about pedagogy in educational foundations courses in today's environment

Folate catabolites in spot urine as non-invasive biomarkers of folate status during habitual intake and folic acid supplementation.

Folate status, as reflected by red blood cell (RCF) and plasma folates (PF), is related to health and disease risk. Folate degradation products para-aminobenzoylglutamate (pABG) and para-acetamidobenzoylglutamate (apABG) in 24 hour urine have recently been shown to correlate with blood folate. Since blood sampling and collection of 24 hour urine are cumbersome, we investigated whether the determination of urinary folate catabolites in fasted spot urine is a suitable non-invasive biomarker for folate status in subjects before and during folic acid supplementation. Immediate effects of oral folic acid bolus intake on urinary folate catabolites were assessed in a short-term pre-study. In the main study we included 53 healthy men. Of these, 29 were selected for a 12 week folic acid supplementation (400 µg). Blood, 24 hour and spot urine were collected at baseline and after 6 and 12 weeks and PF, RCF, urinary apABG and pABG were determined. Intake of a 400 µg folic acid bolus resulted in immediate increase of urinary catabolites. In the main study pABG and apABG concentrations in spot urine correlated well with their excretion in 24 hour urine. In healthy men consuming habitual diet, pABG showed closer correlation with PF (rs = 0.676) and RCF (rs = 0.649) than apABG (rs = 0.264, ns and 0.543). Supplementation led to significantly increased folate in plasma and red cells as well as elevated urinary folate catabolites, while only pABG correlated significantly with PF (rs = 0.574) after 12 weeks. Quantification of folate catabolites in fasted spot urine seems suitable as a non-invasive alternative to blood or 24 hour urine analysis for evaluation of folate status in populations consuming habitual diet. In non-steady-state conditions (folic acid supplementation) correlations between folate marker (RCF, PF, urinary catabolites) decrease due to differing kinetics

The Benefits of Supplementing the Eighth Grade American History Curriculum with Historical and Realistic Fiction Novels

As the textbook remains the driving force of instructional methodology in the secondary history curriculum, student enthusiasm and achievement in the discipline continue to decline. Textbooks, which fail to tell the complete story of the American experience, are not just shortchanging history, they are ill-suited to the developmental requirements of the adolescent learner. Through personal classroom experience, literature review, and a one-year site-based study, the evidence compiled in this study endorses the integration of social studies trade books, in particular historical and realistic fiction novels, as a prescription for diminishing, if not turning around, the discouraging trend in middle school social studies

The Holocaust: A Text Set to Extend Beyond the World History Text

This project examined the use of trade books, particularly historical fiction and nonfiction, in the social studies curriculum. Through the development of this project, a text set was designed to extend and enrich the students\u27 knowledge of the holocaust beyond the world history textbook. The literature revealed strong support for the use of trade books as a vehicle to learn more than the names, dates and facts presented in the textbook. Trade books allow the students to learn about the human experience of historical events, specifically the Holocaust for the purpose of this project. Through historical fiction and nonfiction trade books, a more in-depth understanding of a topic can be accomplished and allow various perspectives to be explored. Unfortunately, due to numerous limitations, textbooks do not do justice with regards to the significance of many historical events; nor do they convey more than one perspective. Textbooks can act as a resource for basic facts, however supplementing them with trade books allows the teacher to extend and enrich student understanding of a topic. · This can have an immense effect on the students\u27 overall understanding of a historical event and how it connects to present day life

Employing geographical principles for sampling in state of the art dialectological projects

The aims of this paper are twofold: First, we locate the most effective human geographical methods for sampling across space in large-scale dialectological projects. We propose two geographical concepts as a basis for sampling decisions: Geo-demographic classification, which is a multidimensional method used for the socio-economic grouping of areas. We also develop an updated version of functional regions that can be used in sociolinguistic research. We then report on the results of a pilot project that applies these models to collect data regarding the acceptability of vernacular morpho-syntactic forms in the North-East of England. Following the method of natural breaks advocated for dialectology by Horvath and Horvath (2002), we interpret breaks in the probabilistic patterns as areas of dialect transitions. This study contributes to the debate about the role and limitations of spatiality in linguistic analysis. It intends to broaden our knowledge about the interfaces between human geography and dialectology
