This paper concerns morphological stability of a similarity solution to the Stefan problem with surface tension and initial supercooling. The linear stability analysis shows that for a nonzero surface tension each perturbation mode with a nonzero wave number is stable. However, the solution is unstable with respect to perturbations with a zero wave number limit point in their Fourier spectrum. ...

Sweet potato virus disease (SPVD) is the most devastating disease of sweetpotato [Ipomoea batatas (L.) Lam.] globally. It is caused by the co-infection of plants with a potyvirus, sweet potato feathery mottle virus (SPFMV), and a crinivirus, sweet potato chlorotic stunt virus (SPCSV). In this study we report the use of cDNA microarrays, containing 2765 features from sweetpotato leaf and storage...

This chapter explores cultural and individual religious roots of adolescents' family orientation on the basis of multilevel analyses with data from 17 cul­ tural groups. Religion and the family are seen as intertwined social insti­ tutions. The family as a source of social support has been identified as an important mediator of the effects of religiosity on adolescent developmental outcomes. Th...
