Although globular cluster horizontal-branch (HB) morphology is determined primarily by the cluster metallicity, observations have shown that clusters with similar metallicities sometimes have very different HB's, indicating the existence of a second parameter. Sweigart (1997, 1999) suggested that deep mixing on the red giant branch (RGB) may be a second parameter if He is mixed into the stellar...

Hybrids composed of phage M13 and plasmid pHV33 were used to study the formation of deletions in Escherichia coli. Eighty to ninety percent of the deletion endpoints were at the position of the nick introduced into the M13 replication origin by the phage gene II protein. This suggests the existence of a novel mechanism of illegitimate recombination.

Smartphones recently expanded the potential for low-cost close-range photogrammetry 3D modeling. They enable simultaneous collection of large amounts data a variety requirements. It is possible to calculate image orientation elements and triangular coordinates in phases as Relative Absolute orientation. This study demonstrates photogrammetric reconstruction approach that performs on tablets sma...

We found that parents of college students report greater goal-autonomy than their children, consistent with organismic, humanistic, and trait perspectives upon positive aging. Parents also had higher levels of positive aVect and lower levels of negative aVect than their children. In a second, retrospective test of the age-to-autonomy relationship, parents reported more autonomy now compared to ...

Building upon earlier observations which demonstrate substantial star-to-star differences in the carbon abundances of M13 subgiants, we present new Keck LRIS spectra reaching more that 1.5 mag below the M13 main-sequence turn-off (to V ≈ 20). Our analysis reveals a distribution of C abundances similar to that found among the subgiants, implying little change in the compositions of the M13 stars...
