In this study, we use a data assimilation framework based on the adaptive Markov chain Monte Carlo (MCMC) algorithm to constrain process parameters in LPJ-GUESS model using CH4 eddy-covariance flux observations from 14 different natural boreal, temperate, and arctic wetlands. The objective is to derive a single set of calibrated parameter values. The calibrated parameter values are then used in th

Seven or eight thousand years ago, as the farthest the human memory can reach, the Egyptians established a great civilization that was considered as the origin of civilization on the Earth. There is no place in Egypt where man cannot find evidence that enlighten this civilization and tell about Egypt's role in most of the world's historic events from the beginning of mankind until the pres

Popular summary Energy generation from renewable sources is one of the main issues to be solved for the 21st century. One of the most advanced technologies currently available is wind energy, which has a large potential onshore and offshore. However, in many cases wind energy is restricted to large wind parks with wind power plants sometimes exceeding heights of 100 m. The construction of large wi

Denna studie undersöker den rumsliga variationen i markens koldioxid-utflöde (CO2) i en boreal blandskog, huvudsakligen dominerad av tall (Pinus sylvestris L.) och gran (Picea abies L.) i ADVEX experimentsite i Norunda, centrala Sverige. Mätningar av markens CO2 gjordes i 72 collars omkring huvudtornet med hjälp av en LI-6250 infraröd gasanalysapparat kopplad till en hemmagjord mörkkammare. Medelv

Today wind power developers are exploring the possibilities of establishing wind turbines in forest areas, therefore improved sound prediction models for complex terrains are valuable. The Swedish model used today is only applicable for hard flat ground without any vegetation, and is not adjustable to any meteorological parameters except the wind speed. The companies DELTA, DONG Energy and EMD Int

We present a solution for long-term direct current resistivity and time-domain induced polarization (DCIP) monitoring, which consists of a monitoring system and the associated software that automates the data collection and processing. This paper describes the acquisition system that is used for remote data collection and then introduces the routines that have been developed for pre-processing of

In recent years, particularly following the definition of the UN Sustainable Development Goals (SDGs) for 2030, Nature-Based Solutions (NBS) have gained considerable attention, capturing the interest of both the scientific community and policymakers committed to addressing urban environmental issues. However, the need for studies to guide decision-makers in identifying suitable locations for NBS i

We report results of detailed empirical valence bond simulations that model the effect of several amino acid substitutions on the thermodynamic (ΔG°) and kinetic activation (ΔG⧧) barriers to deprotonation of dihydroxyacetone phosphate (DHAP) and d-glyceraldehyde 3-phosphate (GAP) bound to wild-type triosephosphate isomerase (TIM), as well as to the K12G, E97A, E97D, E97Q, K12G/E97A, I170A, L230A,

Detaljerade data är avgörande vid karaktärisering av komplexa förorenade områden. I denna studie utrustar vi ett antal G360-brunnssystem med Star-Oddi milli-TD-tryckgivare i ett mestadels PCE (tetrakloretylen)- och TCE (trikloretylen)-förorenat bostadsområde i Helsingborg. Trots att dessa tryckgivare vanligtvis används inom marina undersökningar gör deras kostnad samt kompakta storlek dem av intre

Semi-natural grasslands in Scandinavia have been created by humans since many millennia ago, but the agricultural intensification in the last few centuries caused them to decline heavily. Accordingly, the biodiversity associated to these open, nutrient-poor habitats declined as well and many remnant populations are slowly declining and threatened to go extinct. In this study, I focused on declin

Consumption was one of the spheres of everyday life shaken and remoulded by the collapse of socialist regimes at the end of the 20th century. Especially in times of rapid change, a moral economies lens is a fruitful means to understand the contentious moral landscape and moral tensions that pervade consumption behaviour, norms and discourse. Important areas of consideration in post-socialist socie

In the wake of the deterioration of relations between modern Russia and Poland, the Katyn memorial has become a scene for the contestation of historical memory. In order to play down the 1940 executions of Polish military officers in Katyn, the Russian government has granted belated official recognition to 8,000 victims of Stalinism in the Smolensk region. After being brushed under the carpet in t

In all organisms, chromosome replication is regulated mainly at the initiation step. Most of the knowledge about the mechanisms that regulate replication initiation in bacteria has come from studies on rod-shaped bacteria, such as Escherichia coli and Bacillus subtilisStreptomyces is a bacterial genus that is characterized by distinctive features and a complex life cycle that shares some propertie
