The physical properties of TiAl alloys were studied and compared with that of currently used high temperature materials. TiAl exhibits lower thermal expansion, Babyliss Pro Stockists Uk
higher specific stiffness and higher specific heat. The thermal conductivity of TiAl is comparable to that of superalloys and steels and higher than that of Ti–6Al–4V.
For every prime p and each n = 2, 3,…, ∞, we construct an action of <img height="31" border="0" style="vertical-align:bottom" width="126" alt="" title="" src="http://origin-ars.els-cdn.com/content/image/1-s2.0-S0166864197000084-si1.gif"> on a two-dimensional compact metric space X with n-dimensional orbit space.
In two-outcome strictly competitive games, equilibrium mixed strategies do not depend on ultimate prizes. Dixit and Skeath [Games of Strategy (1999) Norton, New York] find this ‘counter-intuitive’. We show this invariance comes from reduction, not independence; and provide conditions for ‘intuitive’ comparative statics under recursive expected utility.
A new technique has been developed for measuring the differential interfacial tension as a function of potential at solid-solution interfaces. Ghd Sale Durban
The technique utilizes the bending experienced by a thin electrode, insulated on one side, when the interfacial tension is changed. Potentials of zero charge are reported for gold in KCl solution and platinum in H2SO4 solution.
