Energy balance closure is an important feature in studies of ecosystem exchanges of energy and greenhouse gases using the eddy covariance method. Previous analyses show that this is still a problem with imbalances in the order of 0.6–0.7 to full closure (for only a few sites). It has been suggested that mesoscale transport processes that are not captured by the eddy covariance measurements are the
This paper contributes to academic and policy debates about climate leadership by illustrating an approach to examining national emission reduction targets focusing on Denmark. Widely recognized as a climate leader, Denmark is cherished for both its historical track record and its current climate targets. With a target of 70% emissions reduction by 2030 compared to 1990 stipulated in national law,
Koranbränningar ställer höga principer mot varandra, men begränsningar av opinionsfrihet motiveras alltid med oklanderliga skäl. De historiska perspektiven visar att man ska vara försiktig med att ge vika för uppblossande opinioner. Sverige må vara i minoritet i ett globalt perspektiv, men det gör bara försvaret av vår yttrandefrihet än viktigare, skriver professor Jonas Nordin.
In secondary-school English-as-a-foreign-language (EFL) classrooms worldwide, English tends to be used alongside the society or community majority language (Brevik & Rindal 2020; Tsagari & Diakou 2015; Üstünel 2016), and research reveals greater participation and positive attitudes among students when translanguaging is permitted (Ebe 2016; Kleyn 2016; Saxena 2009; Ollerhead 2019; Seltzer
The machining of Fiber Reinforced Polymers (FRP) is accompanied by specific defects such as delamination, uncut fibers, and others. Such defects are unique in their shape and size for different FRP types, used tools, and applied cutting conditions. Therefore, defect recognition and quantification remain a central challenge in the quality control of FRP components from an accuracy and time balance
The dynamic interaction between a non-viscid, compressible fluid and an elastic structure is studied. Finite element formulations, using the weighted residual method, are derived. Different primary variables in the fluid domain are used and different source functions are considered.When a potential field is used, the dynamic interaction between fluid and structure yields nonsymmetric matrices.

Europe is leading the world in cutting carbon emissions. By 2020, the European Union had reduced emissions by an estimated 34 percent compared to 1990 levels, which puts its promised 55 percent reduction by 2030 safely within reach. By comparison, the United States has managed only a 7 percent reduction over the same period.However, this European success story comes with a big asterisk. The EU has
The immune system is integral to cardiovascular health and disease. Targeting inflammation ameliorates adverse cardiovascular outcomes. Atherosclerosis, a major underlying cause of cardiovascular disease, is conceptualized as lipid-driven inflammation in which macrophages play a nonredundant role. However, evidence emerging so far from single-cell atlases suggests a dichotomy between lipid-associa
