Arabidopsis Thaliana RNAs (Stratagene, Spike RNA 201, 204, 205, 208, and 209) were added as reporter exogenous RNAs at different concentrations, either specifically in tester material or in both tester and driver materials.
Semi-quantitative analysis (see methods) revealed that these four clones encode for very abundant cDNA in the tester material : they represented about 0.11, 0.6, 2.45 and 3.7% (for 3P11, 3I20, 3L22 and 3C24 respectively) of blastocyst cDNAs.
We also found that exogenous reporter RNAs were differentially represented among the bacterial colonies, in line with their initial abundance in the tester material (Table 1 and Fig. 2).
The tensile properties of polypropylene (PP) composites filled separately with three kinds of graphene nano-platelets (GNPs) with different size were measured using a universal materials tester at room temperature and rate of extension of 50 mm/min.
We attached hooks to the Inspec 2200 portable bench-top materials tester.
Using an INSTRON Inspec 2200 portable bench-top materials tester (INSTRON, Norwood, MA, USA), the anterior surface of the manus, where claw-closing forces are delivered, was punctured using a conical tip that emulated the shape of the tubercles.
The wear and friction performance was evaluated using a piston skirt-liner contact tester, and the material used was aluminium 6061, which is the standard material for piston skirt.
MARK LANGFORD, ENGLAND Response from Paola Antonelli, curator in MoMA's department of architecture and design The early testers of new materials and innovative solutions, the true pioneers, are not only engineers or scientists.
In order to simulate these conditions a reversed axisymmetrical material tester is designed and constructed.
The powder formulations were compacted to several relative densities with the Zwick material tester.
