A tube with varying cross sections can capture some essential features of the motion of foam in porous media. In this paper, experiments were carried out concerning a moving bubbles train through cylindrical ducts with sinusoidal cross-section. The test tube has total length of 1.14 m and has constrictions at interval of 0.0095 m. The visual images of a single lamella motion were recorded and were interpreted. It is found the lamella decelerates in the diverging portion while accelerates in the converging part of the tube.

The current study used a qualitative image analysis to explore observed interactional behaviors communicated through images printed in Cosmopolitan magazine during the calendar year of 2009 as a means to infer social values . Two general inquiries were used to guide the manner with which behavior was observed: is a heteronormative bias present and what values regarding the expressions of sexual orientation and gender identities can be inferred from these images. The sample consisted of 722 individual images depicting groups of two or more persons. Images were coded for group gender composition, activities engaged in, and physical touch . Results indicated a strong bias favoring heterosexual romantic/sexual intimacy and disfavoring homosexual romantic/sexual intimacy. The differences found between groups of womyn and groups of men suggest the expression of traditional hegemonic gender stereotypes in these image selections. Together, these findings suggest that traditional gender identities and heteronormative ideas were the dominant values communicated in these media image selections.
