Properties, processing and performance of rare and natural fibres : a review and interpretation of existing research results

A substantial up-to-date reference manual has been prepared which documents important issues for the supply chain of rare natural animal fibres. New developments in textiles have been included. Cashmere, mohair and camelid fibres have special properties of softness, smoothness and lustre, when compared with sheep wool. They also have other attributes which affect market prices and consumer perceptions, such as being rare and exotic luxuries, and are associated with expensive, comfortable and exclusive garments. These fibres add to the range of wool processing, and add value to wool textiles. Generally, knowledge about these animal fibres is limited, and research effort small compared with research into wool and other natural and man-made fibres. Compared with wool, rare natural animal fibres are more difficult and costly to process. Knowledge about processing these fibres is kept guarded as industrial knowledge. There are problems with clearly identifying rare natural animal fibres when goods are traded or fibres are blended, and fraud is a major concern for textile manufacturers and industry groups. Prickle discomfort in mohair and alpaca next-to-skin wear is a major concern for consumers and textile manufacturers. Natural colours, whiteness and yellowness of rare natural animal fibres are important fibre attributes for dyers and consumers, and the current products have both positive and negative colour attributes for processors. Past investments by RIRDC have made substantial gains in knowledge about fundamental and applied areas of knowledge on the properties, testing and processing performance of rare natural animal fibres.

Interpretation of ambiguous interoceptive stimuli in panic disorder and nonclinical panic

Cognitive bias in the misinterpretation of ambiguous interoceptive stimuli has been demonstrated in panic disorder. This study investigated whether this cognitive bias also occurs in people with nonclinical panic who are at risk of developing panic disorder. The responses of 25 people with nonclinical panic were compared to those of 20 people with panic disorder and 69 nonpanic controls on a measure of interpretive bias, the Brief Body Sensations Interpretation Questionnaire. There was evidence for interpretive cognitive bias for ambiguous interoceptive stimuli among the nonclinical panickers which did not differ from that of the people with panic disorder, but which differed from the nonpanic controls. High anxiety sensitivity predicted interpretive bias toward both interoceptive and external stimuli. Results therefore suggest that interpretive cognitive bias for ambiguous interoceptive stimuli may be a risk factor for the development of panic disorder.

Physical interpretation of the reference features in textural fractography of fatigue fractures

Reference features of a fatigue fracture surface are the reference texture and reference crack growth rate which are unambiguously mutually related. The reference texture is a subset of the image texture in SEM fractographs. It is expected to be common to all fractures caused by loadings in which significant events occur sufficiently regularly and frequently. The ratio of the reference and the conventional crack growth rate called reference factor is a characteristic of a particular loading. Its value may be related to the sequence of successive sizes of the cyclic plastic zone, while the mechanism of the effect of overloads follows the models of Wheeler and Willenborg. Application to a set of nine test specimens from aluminium alloy loaded by three different loading regimes is shown.

Introduction: of turtles, dining and the importance of history in food, food in history

Feasting on North American moose or Caribbean turtle in Renaissance Italy, Ancient Rome, or the colonial working-class pub, is Social and Cultural history in a new and exciting form. Dining on Turtles traverses time and place to open up food and drink as a new field of historical enquiry. In chapters covering the heritage landscapes of sugar canefields, the reform of popular drinking customs, the importance of eating and drinking culture to Olympic Games planning, and the significance of cookbooks to civic society, historians here break new ground in locating food's importance. From the exploration of French tavern rituals, Scottish feasting on haggis, and memories of food traditions in Cyprus come themes of identity and nationalism, change and continuity.

Towards understanding epistemological assumptions of history teacher educators: my experience with phenomenological enquiry

This paper draws upon the methodological aspect of my thesis project completed in June 2007. At the center of the research problem was the question: How do history teacher educators (HTEs) in Bahir Dar University comprehend the sources and nature of historical knowledge? Phenomenological approach to research was employed in an attempt to explicate invariant structures of their epistemic assumptions of history as a school subject. Accordingly, with six purposefully selected educators as research participants, in the two-month time field work, in- depth interview and essay questions for personal text were used to gather qualitative data. Then, the data were analyzed thematically using an adapted six-phase model and interpretive themes emerged as findings of the study. And it was learnt that the educators have a very muddled conception and unquestioned assumptions on the nature and sources of historical knowledge. With this, also phenomenological enquiry, with difficulties and rewards of its own, was found to be an appropriate strategy to understand personal meaning and beliefs of the educator with regard to disciplinary knowledge of history. The paper, therefore, describes the way I employed phenomenological research approach to understand the case, and presents my personal experience of it as a beginner education researcher.

How does the cookie crumble? legal costs under a uniform interpretation of the United Nations Convention on Contracts for the International Sale of Goods

A family owned Mexican company, Zapata Hermanos Sucesores, S.A. ("Zapata"), sold approximately US$950,000 worth of cookie tins over a period of four years to the Maurice Lenell Cooky Company ("Lenell"), an American company that produced baked goods. Lenell failed to pay Zapata for the cookie tins so Zapata sought legal advice and instituted legal proceedings against Lenell for breach of contract in the Federal District Court of Illinios. The cookie tin sale contracts were governed by the United Nations Convention on Contracts for the International Sale of Goods ("CISG"). Zapata succeeded in its Federal District Court claim and, as part of the Court's order, was awarded US$550,000 as foreseeable loss under Article 74 of the CISG, being the amount of legal fees incurred by Zapata in bringing proceedings against Lenell. On appeal to the Federal Appellate Court, however, the award of legal fees was overturned. The parties now find themselves contesting a leave application to appeal to the Supreme Court of the United States of America in a much anticipated debate over who should pay the lawyers.

An ethological interpretation of zoophycos based on permian records from South China and Southeastern Australia

Abundant, well-preserved Zoophycos is common in the lower and middle Permian paleotropical neritic limestone of South China and in the middle Permian glaciomarine lithic wackestone of southeastern Australia. Zoophycos from both regions is composed of a marginal tube and a tongue-like spreiten complex, the latter itself consisting of primary lamellae in planar view and backfill structures (dark and light menisci) in cross-sectional view. The Zoophycos tracemaker is interpreted to have periodically collected and fed on the surrounding nutrient-enriched sediments within a shallow depth of the seafloor. The dark menisci may correspond to the burrowing phase, whereas the light menisci may be related to a multiple-behavior phase, including dwelling, feeding, farming, resting, and excreting. Symbiotic microorganisms (e.g., sulphate-reducing bacteria) may have been closely involved with the Zoophycos tracemaker in producing the complex structures of the spreiten, based on the abundant pyrite framboids that were found in the Zoophycos spreiten. We suggest that Zoophycos is not simply a biogenic sedimentary structure formed by the motion of the tracemaker; rather it represents a set of complex and elaborate biogenic structures formed by a succession of life behaviors of the tracemaker along with its symbiotic microorganisms. The complete formative process of Zoophycos is reconstructed and linked to its morphology, based on this interpretation.
