Low-cost, programmable infusion pump with bolus mode for in-vivo imaging.

Syringe pumps are routinely used in biomedical imaging laboratories for delivering contrast agents and either infusing or injecting a precise amount of liquids. Commercial syringe pumps that are developed by specialized companies are expensive and only have standard functions, which often do not meet the requirements of individual experiments. In this paper, we demonstrate an open-source single syringe pump with the possibility of adapting to the needs of a researcher.

Hauntings Across the Divide: Transdisciplinary Activism, Dualisms, and the Ghosts of Racism in Engineering and Humanities Education.

In this paper, we report on an intervention across continents and disciplines that brought together differently positioned students in South Africa and the USA. A collaboration between our classes-an introductory Geographic Information Systems (GIS) class in South Africa and a composition class in the United States-was facilitated and investigated by us. The point of departure of the intervention was to service socially just and anti-racist pedagogies through experimentation.
