(the selection is essentially that of the ACS Survey by Sarajedini et al.2007). On the other hand, these are also those GCs for which more precise data can be obtained. A similar bias can of course be present in case spectroscopy is used to define the populations fractions. It would ...
Brass, for example, is a substitution alloy based on copper in which atoms of zinc replace 10–35 percent of the atoms that would normally be in copper. Brass works as an alloy because copper and zinc are close to one another in the periodic table and have atoms of roughly similar size...
For example, when performing machine monitoring, periodic inspection, or prototype development, order analysis can evaluate time for maintenance, critical speeds, and stable operation speeds and determine causes for vibrations. Order analysis is also very powerful in combination with other types of ...
