Stress singularities and the formation of birefringent strands in stagnation flows of dilute polymer solutions [PDF]
J. Non-Newtonian Fluid Mech. 157 (2009) 126-132, 2009 We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the stagnation point in the UCM model and extensions, like the FENE-P model.

Secular Stagnation: The Long View [PDF]
American Economic Review, 2015 Four explanations for secular stagnation are distinguished: a rise in global saving, slow population growth that makes investment less attractive, adverse trends in technology and productivity growth, and a decline in the relative price of investment goods. A long view from economic history is most supportive of the last of these four views.

Canadian Productivity Growth, Secular Stagnation, and Technological Change [PDF]
International Productivity Monitor, 2018 In this article, we show first that the recent slowdown in productivity growth in Canada, similar to that in the United States, can be attributed at least in part to the fall-off in the commercialization of new technologies.

Using the Honey Bee (Apis mellifera L.) Cell Line AmE‐711 to Evaluate Insecticide Toxicity
Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 88-99, January 2023., 2023 Abstract One of the main contributors to poor productivity and elevated mortality of honey bee colonies globally is insecticide exposure. Whole‐organism and colony‐level studies have demonstrated the effects of insecticides on many aspects of honey bee biology and have also shown their interactions with pathogens.

Food Science &Nutrition, Volume 11, Issue 1, Page 590-598, January 2023., 2023 This study suggests a new design for tracking and modernizing the flow of fluid that changes inside according to the shape and material of "Sojutgori", a traditional Korean distiller. Abstract The design of the Korean traditional distiller ‘sojutgori’ was extracted as a digital sketch, and the internal fluid flow in the distillation process was tracked
