Occlusal contact area, maximum bite force measurements, masticatory efficiency, and discriminating hardness assessments were performed on four occasions: (1) before implant surgery with the complete denture in situ, (2) 3 h after surgery, (3) 1–2 weeks, and (4) 3 months after insertion of the provisional screw-retained restoration.
Fifty premolars divided equally into five groups were included in the study for quantitative surface micro-hardness assessment using a micro-hardness tester (MHT).
Quantitative surface micro-hardness assessment of the specimens was done with a digital display Vickers micro-hardness tester (MHT) (Model HVS-50, Laizhou Huayin Testing Instrument Co., Ltd., China).
Microstructure, hardness and wear assessments were used to characterize the coatings.
The critical stress intensity factor, KIC, is a valid replacement for the organoleptic (sensory) assessment of "hardness" or "crunchiness" in fruit and vegetables and suggests that crack initiation and propagation in these foods is controlled by factors similar to those found in engineering materials.
Patients' assessments of hardness of the lesions and presence of pruritus showed improvement with the application of pirfenidone, although the difference was not significant (Table 3).
The disagreements, however, were equally likely to be due to subjective assessments that over- or underestimated ground hardness, compared to the objective assessments (n = 3, each).
You are not hard for hardness's sake.
Consequently, the development of injury prevention strategies based on subjective assessments of ground hardness may not be appropriate or effective.
Subjective, observational assessments of ground hardness and soil moisture were recorded on 36 occasions during an Australian football season using two four-point scales of 'very soft' to 'very hard' and 'very wet' to 'very dry', respectively.
