People who felt more connected to nature also reported higher well-being.
Researchers who study people’s relationship with the natural world often use the term
“nature connectedness.”
This phrase doesn’t simply mean going hiking or visiting a park.
Nature connectedness refers to the extent to which people see nature as part of who they are
– whether they feel an emotional bond with the natural world and experience a sense of oneness with it.

Abstract: This work extends the front propagation formulation (FPF) combustion model to large eddy simulation (LES) of swirl-stabilized turbulent premixed flames and investigates the effects of resolved flame thickness on the predicted flame dynamics. The FPF method is designed to mitigate the spurious propagation of under-resolved flames while preserving the reaction characteristics of filtered flame fronts. In this study, the model is extended to account for non-adiabatic effects and is coupled with an improved sub-filter flame speed estimation that resolves the inconsistency arising from heat-release effects on local sub-filter turbulence. The performance of the extended FPF method is validated by LES of the TECFLAM swirl-stabilized burner, where the results agree well with experimental measurements. The simulations reveal that the stretching of vortical structures in the outer shear layer leads to the formation of trapped flame pockets, which are identified as the physical mechanism responsible for the secondary temperature peaks observed in the experiment. The prediction of this phenomenon is shown to be strongly dependent on the resolved flame thickness, when the filter size is used for modeling sub-filter flame wrinklings. Without proper modeling of the chemical steepening effects, the thickness of the resolved flame brush is over-predicted, causing the flame consumption rate to be under-estimated. Consequently, the flame brush detaches from the outer shear layer, resulting in a failure to capture the flame pockets and the associated secondary temperature peaks.

One of the main areas of pushback that Republican leadership in Congress has faced in trying to pass an extension of "section 702 of the Foreign Intelligence Surveillance Act" (Fisa) is push to keep the bill “clean”,
-- despite GOP hardliners insisting that reforms and additions are needed.
Some members of the conference, like Representative Anna Paulina Luna, a Republican from Florida, have said that
