The microhardness indentation load/size effect in rutile and cassiterite single crystals

Abstract: The microhardness indentation load/size effect (ISE) on the Knoop microhardness of single crystals of TiO2 and SnO2 has been investigated. Experimental results have been analysed using the classical power law approach and from an effective indentation test load viewpoint. The Hays/Kendall concept of a critical applied test load for the initiation of plastic deformation was considered, but rejected to explain the ISE. A proportional specimen resistance (PSR) model has been proposed that consists of the elastic resistance of the test specimen and frictional effects at the indentor facet/specimen interface during microindentation. The microhardness test load, P, and the resulting indentation size, d, have been found to follow the relationship $$P = a_1 d + a_2 d^2 = a_1 d + (P_c /d_0^2 ) d^2$$ The ISE is a consequence of the indentation-size proportional resistance of the test specimen as described by a 1. a 2 is found to be related to the load-independent indentation hardness. It consists of the critical indentation load, P c, and the characteristic indentation size, d o.

The Impact of Acceptance versus Control Rationales on Pain Tolerance

Abstract: Acceptance approaches, which have been receiving increased attention within behavior therapy, seek to undermine the linkage between private events and overt behavior, rather than attempting to control the form or frequency of private events per se Research comparing control versus acceptance strategies is limited The present study examined the behavioral and subjective impact of a control-based versus acceptance rationale, using a cold pressor task Subjects in the acceptance group demonstrated greater tolerance of pain compared to the control-based and placebo groups Only the control-based rationale targeted the subjective experience of pain but it did not differ across rationales Results confirmed that acceptance was effective in manipulating the believability of reason giving, a key process measure By encouraging individuals to distance themselves from their private events, acceptance methods may help reduce the use of emotional reasons to explain behavior and hence shift concern from moderating thoughts and feelings to experiencing the consequences of one’s action Acceptance is a promising new technique Its effect is all the more surprising given that it teaches principles (eg, “thoughts do not cause behavior”) that run counter both to the popular culture and to the dominant approaches within empirical clinical intervention
