The diets of many butterflies and moths change dramatically with development: from herbivory in the larvae to nectarivory in the adults. These diets are nutritionally distinct, and thus are likely to contribute differentially to egg manufacture. We examine the use of dietary resources in egg manufacture by four butterfly species with different patterns of oviposition and lifespan; three in the ...

Vinyl flooring manufacturers use plasticizers to decrease the viscosity and increase the pliability of vinyl. Several ignitable liquid plasticizers used in the manufacture of vinyl flooring were identified and investigated in this study. Twenty-nine collections from five major vinyl manufacturers, a total of 72 samples, were analyzed using passive headspace concentration in accordance with the ...

Samples of aluminosilicate refractory after operation in the shaft and hearth a coke-gas cupola were investigated; this was used for smelting cast iron with spheroidal graphite using carbon wastes from aluminium electrolysis production as reducing agent. Use only fluorine-containing solid fuel allows to utilize hazardous man-caused wastes, improves economic performance has influence on resistan...

The manufacture of miniature Stirling cycle cryocoolers, using standard micro-machining techniques and materials has been pursued by the authors [1]. A MEMS based cryocooler would allow integration of a cryogenic cooling system directly into a cryoelectronic device. Resonant bossed diaphragms were proposed as the means to sweep the working gas in the Stirling cooler, replacing the pistons and d...

with high energy density, which makes it useful for storage and transportation over long distances from the gas fields to the consumers. LNG is recovered from natural gas in largescale liquefaction plants. Process automation is a key issue in LNG plants to ensure cost efficient plant operation and high product quality. Process analyzer deliver important data therefore. Siemens Sensors & Communi...

• Two low-cost hollow silica nanoparticle synthesis routes. Scalable, general production of soft ceramics by high-shear mechanical mixing. An effective – fiberglass crosslinked network for thermal insulation. Ultralow conductivity 0.023 W -1 m K with robust flexibility. Hollow-structured materials show promise in insulation because the shells encapsulating gaseous voids can interrupt heat trans...
