Purkinje cells are involved in many vital functions within the body. Twenty ovine fetuses ranging from 2 to 5 months of gestation, two lambs in the first week after birth and three adult sheep were studied. Sections of the cerebellum were stained with haematoxylin and eosin, cresyl violet and Klu¨ver–Barrera. This study indicates that Purkinje cells began to appear after the 15th week of gestation. There were varying degrees of development of Purkinje cells in different zones of the cerebellum. Our findings in sheep fetuses suggest that the maturation of Purkinje cells starts in the caudal regions of the cerebellum and that the process begins in the vermis before it does in the cerebellar hemispheres. The alignment of Purkinje cells was found to be very regular in the caudal regions of the cerebellum. A partial absence of Purkinje cells in the rostral regions of the cerebellum was observed in both sheep fetuses and adult sheep. In the first post-natal week, some ectopic Purkinje cells were found in the white matter of the cerebellum. [less ▲]

High speed steels (HSS) are used in applications where enhanced mechanical properties together with hot oxidation and wear resistances are required. Such an improved physico-chemical behaviour is mainly due to the presence of primary carbides within the microstructure. Depending of the initial chemical composition several types of carbides can precipitate in HSS such as MC (Nb and V-rich), M2C (Mo and W-rich), Cr-rich M7C3, etc. Two groups of HSS were analysed in this study, which are the so-called cast HSS grades that are manufactured by a centrifugal casting process and the cladded HSS manufactured by laser cladding. Purpose: Quantify the carbide volume fractions and the grain size within HSS grades in order to set correlations between the microstructure and both the mechanical and the tribological properties of the materials. Findings: The metallurgical features such as carbides nature and shape have been determined that are related to the manufacturing process of the studied material, and several methods have been used to quantify the carbide volume fractions and to assess the grain size.

Abstract BACKGROUND: The allergen Der p 3 is underrepresented in house dust mite (HDM) extracts probably due to autolysis. Recombinant stable molecule of the allergen is thus needed to improve the diagnosis of allergy and the safety and efficacy of immunotherapy. OBJECTIVE: The current study reports the immunological characterization of two recombinant molecules of the HDM allergen Der p 3 as useful tools for diagnosis and immunotherapy. METHODS: Recombinant mature (rDer p 3) and immature (proDer p 3) Der p 3 and their corresponding S196A mutants were produced in Pichia pastoris and purified. The stability, IgE-binding capacity and allergenicity of the different proteins were analysed and compared with those of the major mite allergen Der p 1 used as a reference. Additionally, the immunogenicity of the different allergens was evaluated in a murine model of Der p 3 sensitization. RESULTS: Compared to the IgE reactivity to recombinant and natural Der p 3 (nDer p 3), the mean IgE binding of patient's sera to rDer p 3-S196A (50%) was higher. The poorly binding to nDer p 3 or rDer p 3 was due to autolysis of the allergen. Contrary to Der p 3, proDer p 3 displayed very weak IgE reactivity, as measured by sandwich ELISA and competitive inhibition, rat basophil leukaemia degranulation and human basophil activation assays. Moreover, proDer p 3 induced a TH 1-biased immune response that prevented allergic response in mice but retained Der p 3-specific T-cell reactivity. CONCLUSION: rDer p 3-S196A should be used for the diagnosis of HDM allergy elicited by Der p 3, and proDer p 3 may represent a hypoallergen of Der p 3. [less ▲]

For optimizing a liquid chromatographic method, direct modeling some responses like minimum resolution is sometimes difficult to perform. By modeling the retention time at apex and the times associated to 13.4% of the peak height, it is possible to obtain estimations of these responses using an adequate cascade of equations, these equations being the definitions of these responses. As a multi-criteria decision has to be taken in most of these optimizations, a Derringer's function can be defined for each response of interest and a overall desirability, on which the final is taken, can be derived. In addition, the chromatogram in any experimental point can be predicted. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

This study aims at analyzing the development processes of rice vermicelli in Dinh Ke and Thu Duong villages of Bac Giang province. The authors conducted a survey with 66 households involving rice vermicelli production and 51 households who did not involve. In combination with in-depth interviews with representative leaders of "Cooperative of production and trading of rice vermicelli in Dinh Ke" and "Association of production and consumption of Chu vermicelli in Luc Ngan district", the data indicated that not only did the development of traditional craft villages bring high income for farm households but they also helped to conserve Vietnam cuisine culture. In order to develop traditional craft villages, it is necessary to re-establish linkages from a production stage to marketing of products, to ensure adequate facilities for drying products, and to impose strong sanction to deal with illegal trading.

The development of riveting technology in iron and steel structures in the 19th and 20th centuries were highly promoted by patents. Although riveting was widely used in buildings and civil engineering structures, little information about the development of this technology – how rivets were manufactured, various installation techniques – is available in literature. This paper discusses a database of patents related to riveting technology that was created to better understand the innovations in riveted connections and their technological evolution. The database includes patents relating to rivets registered in Belgium between 1830 and 1940. Belgian patents are a good proxy for inventiveness in riveting technology in this period, in industrialized countries generally, not only Belgium. As one of the most industrialized countries, Belgium attracted inventors from many countries seeking to register their inventions: foreign inventions represented approximately 75% of all patents. Breakthroughs by important Belgian, French, British, and American inventors/companies are represented in this source. A methodology based on both quantitative and qualitative analyses was implemented. The quantitative analysis dealt with the entire database and explored several key parameters, for example, the subject of the patent and the patenting organization/person. The database also permitted qualitative analyses; specifically, it helped enlarge our understanding of pioneering inventors and their inventions, in the important categories of rivet manufacturing (1855-1870) and installation techniques (1895-1910). As background for the conservation and renovation of historic iron and steel structures, it is vital to have an understanding of the know-how that was available over time. This kind of information is revealed in the patent record [less ▲]
