Algorithm for calculating turbine cooling flow and the resulting decrease in turbine efficiency [PDF]

open access: yes
An algorithm is presented for calculating both the quantity of compressor bleed flow required to cool the turbine and the decrease in turbine efficiency caused by the injection of cooling air into the gas stream.

Revisiting International Political Leadership: Nordic Leadership in Informal Intergovernmental Climate Organisations

open access: yesGlobal Policy, EarlyView.
ABSTRACT The growing significance of informal intergovernmental organisations (IIGOs) in global politics necessitates a re‐evaluation of leadership dynamics. We develop a theory framework that enables us to explain why countries take on leadership roles in IIGOs, with a specific focus on climate politics.

Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...
