Wind tunnel flow generation section [PDF]

open access: yes, 1974
A flow generation section for a wind tunnel test facility is described which provides a uniform flow for the wind tunnel test section over a range of different flow velocities. The throat of the flow generation section includes a pair of opposed boundary

The Effect of Wind Power Generation on Distance Relay Performance

open access: yesAndalas Journal of Electrical and Electronic Engineering Technology, 2022
Wind Power Plants utilize induction generators to generate electrical power. This type of generator produces less short circuit current than synchronous generators; hence it may affect the operation of transmission line protection relays.

The Role of Community Values in Wind Energy Development: Exploring the Benefits and Applications of Community Wind for Reducing Local Opposition to Wind Energy Systems [PDF]

open access: yes, 2008
Worldwide, wind energy generation is growing rapidly as a cleaner and less invasive alternative to traditional fossil-fuel energy sources. Yet, in the United States, the advancement of wind energy has been stunted by three factors: (1) the uncertainty of

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
