Abstract In order to improve the utilization rate of mortar powder in concrete, influence on workability, compressive strength, impermeability, and volume stability recycled concrete was studied by using control variable method. The results show that aggregate can workability mechanical properties containing appropriate amount powder. content is less than 5%, strength will gradually with increa...

We analyse the effects that the impermeability constraint induces on the equilibrium shapes of a three-dimensional vesicle hosting a rigid inclusion. A given alteration of the inclusion and/or vesicle parameters leads to shape modifications of different orders of magnitude, when applied to permeable or impermeable vesicles. Moreover, the enclosed-volume constraint wrecks the uniqueness of stati...

Partial interval recording (PIR) is a procedure for collecting measurements during direct observation of behavior. It is used in several areas of educational and psychological research, particularly in connection with single-case research. Measurements collected using partial interval recording suffer from construct invalidity because they are not readily interpretable in terms of the underlyin...

In this project, we are experimentally testing the importance of burdens of proof in determining the validity of a patent in litigation. The genesis of these experiments is the Supreme Court decision in Microsoft Corp. v. i4i Limited P'ship, 131 S. Ct. 2238 (2011). In i4i, the Court rejected Microsoft's claim that a jury need only be persuaded by a preponderance of the evidence to find a patent...
