Increasing expansivity of automotive headliner is a key agenda behind these efforts.
The molar volume at 265[degrees]C can be calculated with the molar thermal expansivity [E.sub.g] (0.042 [cm.sup.3] mol [K.sup.-1]) and molar volume [V.sub.g] (143.2 [cm.sup.3] [mol.sup.-1]) at the glassy state, [E.sub.1] (0.094 [cm.sup.3] mol [K.sup.-1]) at the liquid state, and a glass transition temperature [T.sub.g] of 353 K measured with a Mettler Toledo DSC 822e, leading to [40]:
where [beta] and [c.sub.p] are the thermal expansivity and the specific heat at constant pressure of the fuel, respectively [33].
In addition, forged products made from Shotic also show high strength, high abrasion resistance, and low thermal expansivity. In order to make these products contribute to further weight reduction of automobiles, we believe we should furthermore improve our aluminum alloy production technology, aiming to realize higher strength.
This had become even more significant due to expansivity of gas and electricity sectors due to inclusion of vast quantities of imported LNG and energy linked projects under China-Pakistan Economic Corridor (CPEC), sources said.
Four, this will either set them conceptually and perhaps concretely--against the historical working class still preserved within contemporary social democratic visions (visions which, despite occasional and often indifferent lip service to racialized exclusion, retain a world-picture of social reorganization derived entirely from the presumption of continued expansivity of absorptive capital), or we will develop an expanded sense of the proletariat as a new unity of lumpen and labor--allowed precisely by the weakening of intra-class competition which follows, dripping immiseration, from the end of absorption.
The addition of PG-LFA and PG-LFA-BOF effectively converts the soil from an expansive clay to a clay of low expansivity. The local TRH4 specification recommends low plasiticity clayey soils (CLs) as good candidate materials for modified pavement subgrade.
There exists an obvious and more direct link between expansivity and sensitivity dependence on initial conditions.
