We developed a model for the electrical field within the polymer material contaminated with a sharp conducting defect (a metallic needle) and defined a parameter characterizing the resistance of polymer to electrical treeing.
"Over all, we found no evidence suggesting undue influence or pressure on N.H.T.S.A.'s employees conducting safety defect investigations, and N.H.T.S.A. had adequate controls in place to ensure employees' compliance with ethics requirements," Calvin L. Scovel III, the inspector general, wrote in a letter.
For the data treated in Section 6, we conducted this defect rate evaluation after 100 iterations of samplings.
Last month Consumer Reports reported the federal agency "conducted fewer defect investigations last year than at any time in its history a dramatic shift that some consumer advocates say could mean dangerous defects are likely to surface down the road.
The Raman test was also conducted to investigate the defect level of synthesized CNTs.
The comparison between PFAC and NPFAC indicates that NPFAC is an appropriate methodology to conduct safety assessment with defects when data information is inadequate.
After incision, preparation of a mucoperiosteal flap, debridement of scar tissue, and exposure of the defect were conducted.
Bone segment transport (BST) over a 60-mm femoral defect was conducted on eight human femora (four cadavers) under constant load measurement.
The first example of defect engineering conducted by Xie and co-workers focused on the exposure of additional active edge planes by forming cracks on the surfaces of nanosheets (Fig. 8a) [42].
Main adjusted analyses were conducted for each birth defect, adjusting for the following a priori potential confounders (selected based on previous literature): study site and maternal age at delivery, body mass index, education, race/ethnicity, income, parity, folic acid use, smoking, and season of conception.
