Establishing suitable groups of students is one the factors considered as a key to success in group collaboration. In addition, searching for optimal solution problem can be more complicated and becomes an exhaustive search, while taking into consideration equality homogeneity. However, few approaches focus on forming based analysis variance (ANOVA) ensure that all generated have been drawn fro...

We present detailed abundance measurements for 45 globular clusters (GCs) in galaxies (and, one case, beyond) the Local Group. The are based on new high-resolution integrated-light spectra of GCs NGC 185, 205, M31, M33, and 2403, combined with reanalysis previous observations Fornax dSph, WLM, 147, 6822, Milky Way. cover range -2.8 < [Fe/H] -0.1 we determined abundances Fe, Na, Mg, Si, Ca, Sc, ...
