Spatial Variability of Albedo and Net Radiation at Local Scale Using UAV Equipped with Radiation Sensors

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

Green frontrunner or indebted culprit? Assessing Denmark’s climate targets in light of fair contributions under the Paris Agreement

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,

”Att göra avsteg från yttrandefriheten är ett sluttande plan”

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.

Translanguaging in EFL with students transitioning to secondary school : Towards a best practice

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

Recognition of drilling-induced defects in Fiber Reinforced Polymers using Machine Learning

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

Finite Element Modelling of Fluid-Structure Interaction

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.

Beware Europe’s New Green Colonialism

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

Lipid-associated macrophages transition to an inflammatory state in human atherosclerosis, increasing the risk of cerebrovascular complications

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
