Effect of the number of blades and solidity on the performance of a vertical axis wind turbine [PDF]

open access: yes, 2016
Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the two-bladed turbine and the other ...

THE DISEASED MIDDLE TURBINATE. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1903
The undue importance which has been given the lower turbinate bodies in the search for the etiology of nasal disorders has overshadowed all other parts of the nasal cavities and led to wrongfully crediting the lower turbinate with the more important instead of the less important role in the production of nasal disease.
