Minutes later
HBU were back in front, but it wasn't long before Stewart was to grab his hat-trick and tie the game once more at 4-4.
The improvement in heat build-up (
HBU ctrl--HBU test sample) cured for 22 hours and tested under loads of 11 or 22 kg is given in figure 8.
Middlesbrough started uncharacteristically nervously, giving up possession easily and allowing
HBU to dictate the pace.
In OESBR tread compounds, high
HBU was observed for the N234 compound at all temperatures.
Given the current regeneration of interest in
HBU, it may be beneficial to look at the theoretical rootstock from which the concept and current definitions have grown.
* Goodrich Flexometer heat buildup (
HBU)--Button specimens 17.8 mm in diameter and 25.4 mm height were press cured.
The fact that the property could objectively and reasonably have been developed is sufficient support for applying the hypothetical development value in the
HBU formula.
Unfazed by the added atmosphere, Boro continued to test the
HBU defence and soon took the lead through a Michael Ableson penalty.
As the contemporary theorists emphasize, "The Lagrangian functions illustrate the significance of the cost of capital and the cost of productive inputs in the identification of the
HBU [highest and best use] that maximize the net present value of the site use."(18) In essence, the Lagrangian functions of the contemporary theorists pick a highest and best use that optimizes a variety of variable relationships based on assumed values of variables.
