Resistance, French

Cordierite bodies can be formed from pure talc (44%), plastic kaolin (41%) and alumina (15%) or from 50/50 mixtures of kaolin and chlorite. Cordierite has very low coefficients of thermal expansion (CTE), which accounts for its use in kiln furniture and automotive catalysts supports. Firing temperatures have to be much higher for the pure talc containing bodies. The talc based body is preferred for automotive catalyst supports although it is more expensive, it is possible to get better control of minor elements such as iron and calcium which have a major impact on CTE. For kiln furniture, chlorite-hased bodies are preferred because of their lower cost and better high temperature creep resistance. In kiln furniture modified with rnnUite to improve shock resistance, French sourced chloritic talc is utilized. [Pg.790]

To check if PemB is surface exposed, E. chrysanthemi cells were subjected to proteolysis. Treatment of the cell suspension with trypsin, proteinase K or chimotrypsin at a concentration of 0.1 to 1 mg/ml for 1 h did not cause PemB proteolysis or its liberation into the medium. Cell pre-treatment with EDTA-lysozyme, which renders the periplasmic proteins accessible to proteases, gave no effect. PemB was also resistant to proteolytic digestion in extract of cells disrupted by sonication or in a French press. Only addition of Triton X-100 (up to 0.1%) causing formation of the micelles with PemB lead to a quick proteolyis of this protein (data not shown). In another approach to analyse the PemB exposition, bacterial cells were labelled with sulfo-NHS-biotin. This compound is unable to cross membranes and biotinylation... [Pg.839]

Institute of Technology (Reese et al., 2003). Using optical lithography to etch away photolithographic resists on stainless steel foils, french pens were designed with a rectangular geometry of 6 p in depfh, 30 p in width with 30 p sidewalls at the tips. To add structural support, the features anterior to the tip were expanded out so that the width of the sidewalls increased to 120 p with a trench width set at 90 p. [Pg.109]

While still on the topic of words and language, I can t resist mentioning French playwright Antonin Artaud, who once said, All true language is incomprehensible, like the chatter of a beggar s teeth. I was never 100 percent sure as to what he meant by this, and many people considered him insane. Perhaps Artaud would agree with the observation my friends at work often make When people talk, what is actually communicated is often much less than what each party intended to communicate. ... [Pg.71]

P. Vieille devised in France the stability test known as l epreuve a 110°C de Vieille (l epreuve au premiere rouge), but it proved to be of no practical value until it was modified by Commandant Lepidi and became known as l epreuve I la resistance totalisee (Test for Total Resistance). Both of these tests, of which the 2nd test became French official, are described in Vol 1 of Encycl, p XXI, under Resistance to Heat Test ... [Pg.145]

Dutch, British and French empires with modern ideas of sovereignty and bureaucracy. All Southeast Asians became aware of the claims and functions of modern statehood aristocrats were deprived of their arms and their slaves all were subjected to the monopoly of a single state system of laws, with origins far distant from them. This imposition of a new order was resisted passionately by some, in the name of dynastic pride (Burmese, Vietnamese, Acehnese, Balinese), nascent ethnie nationalism (Vietnamese, Acehnese, Batak, Javanese), or OSH-flavoured Islam (Tausug, Magindanao, Acehnese). Most however adapted quickly to the modern opportunities offered by the broader worlds they now entered. The new states were useful, and above all they were identified as modern by the new educated groups, but they remained for the most part alien and remote—as indeed they were intended to. [Pg.22]

The second invasion came in 1865 when attempts to control the root aphid Phylloxera through the importation and use of Phylloxera-resistant root stocks inadvertently introduced vine downy mildew, Plasmopara viticola, into the French vineyards. This stimulated what is regarded as the major breakthrough in fungicide use when Millardet, in 1885, acting upon a chance observation, developed the use of Bordeaux mixture, a cocktail of copper sulfate and lime, which is still used extensively in vines and many other crops. [Pg.75]
