Avoid yellowed, spotty, stringy, oversize or split specimens, for obvious reasons.
Split specimens were included so that within- and between-batch coefficients of variation could be calculated.
These specimens showed no differences in sensitivity when compared with split specimens, neither on day 4 (p = 0.89) nor on day 7 (p = 0.74; Table 3).
Split Specimens: This is a procedure used by some labs.
Five series of wedge-splitting specimens for dam concrete with maximum aggregate size of 150 mm were tested, casting in the site of an actual super-high arch dam with its mixing tower system.
By virtue of the mixing tower system in the site of a super-high arch dam, the wedge splitting specimens with the maximum aggregate size of 150 mm were poured in summer and in winter seasons, respectively.
Accurate determination of such a load-COD is crucial for assessing the work-of-fracture applied to split the specimen into two halves.
The method is exemplified in an analysis of the end-loaded split (ELS) specimen, commonly used to determine fracture energies of adhesive layers.
These investigators obtained ascites or serum specimens from women with ovarian carcinoma, split these specimens into two aliquots and used them to isolate (1) exosomes by the gradient density centrifugation and (2) MV by the two-step chromatography/centrifugation procedure.
The highly divergent lineage that includes specimens from Egypt and Israel (see Results) is estimated to have split from specimens further west in Algeria, Morocco, Western Sahara and Mauritania approximately 6.1 Ma ago (95% HPD: 3.9-8.6).
