Abstract: A corrosion-resistant lath is provided for use in exterior finishing systems, such as stucco systems and exterior insulation and finish systems (“EIFS”). The lath includes in a first embodiment an open, woven fabric comprising weft and warp yarns containing non-metallic fibers, such as glass fibers. A portion of the weft yarns are undulated, resulting in an increased thickness for the fabric. The fabric is coated with a polymeric resin for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making an exterior finish system and building wall including an exterior finish system using such a lath.

Abstract: A process is described for converting a precatalyst which comprises an inert support, an organic carbon source and a multimetal oxide comprising silver and vanadium to a gas phase oxidation catalyst which comprises the inert support and a catalytically active silver vanadium oxide bronze, by treating the precatalyst thermally at a temperature of at least 350° C. in a gas atmosphere which comprises less than 10% by volume of oxygen, wherein, before the thermal treatment, the amount of the carbon source in the precatalyst is adjusted to a value below a critical amount The carbon content is reduced by burning-off at a temperature of from 80 to 200° C. in an oxygenous atmosphere with decomposition of a portion of the carbon source. The catalysts obtained serve for the gas phase partial oxidation of aromatic hydrocarbons to aldehydes, carboxylic acids and/or carboxylic anhydrides.

Abstract: The present invention is in the field of genetics, especially plant genetics, and provides agents capable of controlling gene expression. The present invention specifically provides sequences of naturally occurring, tissue-specifically expressed microRNAs. The invention further provides for transgenic expression constructs comprising sequences encoding said microRNAs. By incorporation of the microRNA encoding sequence the expression from said expression construct is specifically silenced in the tissue where the naturally occurring microRNA is naturally expressed. Thereby the expression profile resulting from the promoter is modulated and leakiness is reduced. The invention further provides for a method for modulating transgenic expression by incorporating sequences encoding said microRNAs into transgenic expression constructs.
