However, we argue that the Mechanical Turk sample is essentially useless because it contains no one below a certain threshold of digital literacy; the Facebook sample does contain subjects from this relevant population, but our survey instrument posed such a technical challenge to these subjects that only a (non-random) minority of those who began the survey finished it.
The critical importance of sample mass rather than increment mass, correct sample cutter design and operation, disallowing non-representative sampling from stationary situations, and the benefits of routine inspection of mechanical sampling systems are specifically discussed.
This mechanical grinded sample was denoted as "MG-YAlB14.'' Another method was the synthesis of Y x Al y B14 via Y0.56B14 (denoted as "vYB-YAlB14").
Briefly, after mechanical mincing, samples were dissociated by incubation with 0.1% collagenase and 0.0125% hyaluronidase in PBS (all from Sigma) for 45 min at 37°C and filtered through a 70 µm cell strainer.
Briefly, after mechanical testing, samples were weighed and then were digested in papain at 60°C.
The development of a new typology of enhanced steel reinforcing bars is presented, including aspects related to the industrial production process, microstructural and mechanical characterization of achieved samples, is presented.
Finally, addition of up to 30 wt% of the inert ceramic powder γ-LiAlO2, while improving the mechanical properties of the samples, is found to have a negligible effect on ionic conductivity.
Another way to show the effect of processing parameters on the mechanical properties of welded samples is the main effects plot obtained from DOE for tensile strength.
Mechanical shearing of the samples is also caused by the grinding action of the mixing screws inside the HS reactor.
Figure 4c shows uniaxial tensile testing results for repeatedly recycled samples and despite slight mechanical degradation after each recycling treatment, the overall mechanical performance of the recycled sample is reasonably good.
