The intra-specimen coefficient of error values for the measured DNA content of all the examined hippocampal pyramidal layers were below 0.06 (Fig. 1c), indicating acceptable levels of precision [36].
The surface textured specimens provide low coefficient of friction compared with plain (dimple-free) surfaces.
The contact between wafer and specimen results in a coefficient of friction μ reaching its maximal value of 0.5 every 60° of rotation.
Combining with the low temperature material properties and the boiling heat transfer coefficient of specimen immersed in the liquid nitrogen, a numerical model based on metallo-thermo-mechanical couple theory was established to reproduce the deep cryogenic treatment (DCT) process of a newly developed cold work die steel Cr8Mo2SiV (SDCr8Mo2SiV
Results indicated that for all specimen/distribution combinations, the apparent modulus of the whole specimen decreased nonlinearly with increasing coefficient of variation (COV) of tissue modulus within the specimen.
The ZrC reinforced specimens showed the lower coefficient of friction and maximum wear resistance.
Having finished the tests, the weight losses of the specimens were measured, the coefficient of friction values were calculated, optical and SEM investigations were performed and finally the wear behaviour of conventionally used sliding bearing alloys was characterized.
Experimental results show that plenty of white precipitation generated on the section surface after curing 21 days and the apparent water permeation coefficient of specimens changed slightly after restoring 28 days.
Within eight replicates of the same type of specimens, the average correlation coefficient of array expression signals was very high at 0.96 ± 0.02 which showed an impressive technological reproducibility.
From this theory, relationships between the number of specimens in a group, the coefficient of variation obtained after testing the specimens, the targeted precision index and confidence interval are given.
The friction coefficient of a specimen can be dramatically decreased by plasma RE nitrocarburizing, whereas the corrosion resistance is deteriorated.
