This compares to a 5%to20%0% bore length reduction when using thermally enhanced HDPE with a single U-pipe, double U-pipe, or a combination of both.
While previous research showed potential advantages of using coaxial GHEs, none of the above authors have investigated the possible bore length reduction associated with coaxial configurations.
Design calculations were performed in this study using analytical models with the objective of evaluating the possible bore length reduction that can be achieved when using coaxial GHEs for ground-coupled heat pumps.
The large coaxial GHEs with a high heat storage capacity provided more bore length reduction than the double U-pipe GHEs even though the borehole thermal resistance was higher.
The bore length reduction for the single U-pipe GHEs with thermally enhanced HDPE can be more than 8% when the subsurface thermal conductivity is 4.5 W m−1 K−1 or higher (Raymond et al. 2011a).
There reportedly is a projected cut in bear-incident-reduction at Yosemite.
An alternative set of semantic and syntactic conditions of reduction bear a counterfactual interpretation.
The risks that investors cannot control and are not prepared to bear are: Yield reduction risk: The risk that not enough yields will be produced from the project, or that there will be no enough yield to recover the operation and investment cost of the project.
So, whenever you hear people talking about Ryan's deficit reductions, bear in mind that over the first decade all of the alleged deficit reduction comes from revenue and spending numbers that are simply asserted, not the result of any policies actually described in the "plan".
And the whole community suffers from the devastating cuts in council services as a consequence of the government's deliberate decision to make local government bear the largest reductions in funding.
While these constructions, and the associated graph reductions bear striking similarity with lambda calculus with explicit substitutions, as first remarked by Di Cosmo & Kesner (1997), they are too similar to the corresponding sequent calculus rules: the parallelization effect so elegant for MLL does not properly carry on here, and the graph reduction rules involve boxes and are not local.
