Effekter på mossammansättning vid avverkningar i tallskog i södra Sverige Andelen skyddad skog är idag låg och för att ta reda på hur arter och mångfald kan bevaras måste produktionsskog studeras. Bottenskiktet i form av t.ex. mossor har stor betydelse för förekomst av andra artgrupper och även kommersiellt vid skogsföryngring. Sedan tidigare finns studier på långtidseffekter av kalavverkning me
We introduce lower-bound certificates for classical planning tasks, which can be used to prove the unsolvability of a task or the optimality of a plan in a way that can be verified by an independent third party. We describe a general framework for generating lower-bound certificates based on pseudo-Boolean constraints, which is agnostic to the planning algorithm used. As a case study, we show how
Evaluating the subground properties during the initial stage of a construction of building is important in order to estimate the suitability of soil quality to the technical requirements of bearing capacity, resistance to stress, and strength. This study presented the evaluation of the geotechnical properties of soil intended for the construction of Max IV facility of Lund University, performed in
To help meet emission standards, hydrogen sulfide (H2S) from geothermal production may be injected back into the subsurface, where basalt offers, in theory, the capacity to mineralize H2S into pyrite. Ensuring the viability of this pollution mitigation technology requires information on how much H2S is mineralized, at what rate and where. To date, monitoring efforts of field-scale H2S reinjection
Stora flygningar av små fåglar: Dubbelbeckasinen når höga höjder – flera gånger om Flyttfåglar har länge fascinerat människan. Under lång tid visste vi väldigt lite om var fåglarna tog vägen på vintern, och än mindre hur dessa flygningar faktiskt genomfördes. Under det senaste årtiondet har utvecklingen av små mätapparater (”loggar”) gjort att vi nu vet betydligt mycket mer om vart fåglarna tar vTracking birds throughout their migratory flights have reached new heights during the last decades, as new technology has made it possible to track birds during with higher accuracy than ever before. In this study, I have used accelerometer and air pressure data to mainly address the questions of altitude selection and changes during long distance non-stop migration in the Great Snipe (Gallinago m
This article is devoted to a study of the Hardy space Hlog(Rd) introduced by Bonami, Grellier, and Ky. We present an alternative approach to their result relating the product of a function in the real Hardy space H1 and a function in BMO to distributions that belong to Hlog based on dyadic paraproducts. We also point out analogues of classical results of Hardy-Littlewood, Zygmund, and Stein for Hl
