Energy Science &Engineering, EarlyView.Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Numerical Study of Vortex Structure in the Shear Layer between Swirling Backflow and Axial Main Flow
Journal of Fluid Science and Technology, 2007 The present paper treats the backflow vortex structure observed at the turbomachinery inlet at reduced flow rate. It is caused by the roll-up of the shear layer between swirling backflow and axial main flow.

Lactation, Childrearing, and Gender Justice
Journal of Applied Philosophy, EarlyView.ABSTRACT In this article, I discuss the significance of early infant feeding choices for the goal of gender justice. Focusing on human lactation practices, I identify Exclusive Gestational Nursing (EGN) as the norm in advanced industrial societies, which creates the expectation and permission for gestators, and only gestators, to nurse children, and ...
