Using an inclined screw brings many advantages compared to traditional methods, e.g. high load-bearing capacity, fast and easy montage and high fire resistance. This report contains a study of the influence end- and edge distances have on the load-carrying capacity in joints with inclined screws. Tests were carried out in order to determine if a few of the end- and edge distances proposed by Kevar

Organized crime in Sweden has increased despite the Government’s 34-point action program against gang crime. Previous studies show that schools have an important role in preventing young people from entering the criminal life. But there are no Swedish studies that examine teachers’ implementation of crime prevention measures and therefore, there seems to be a need to investigate this. The research

The balance between the availability of energy and nutrients is decisive for the growth and survival of organisms. Here, we evaluated how energy, in this study expressed as total carbon (TC), is lost along the land to ocean aquatic continuum (LOAC) in relation to nutrients, i.e., total phosphorus (TP), total nitrogen (TN), total iron (TFe), and dissolved silica (DSi). For the evaluation, we used d

Continuous water-table (WT) measurements from peatlands are scarce and – if existing at all –very short. Consequently, proxy indicators are critically needed to simulate hydrological changes in peatlands over longer time periods. In this study, we demonstrate that tree-ring width (TRW) records of Scots pine (Pinus sylvestris L.) growing in the Čepkeliai peatland (southern Lithuania) can be used as

Arbuscular mycorrhizal fungi (AMF) are commonly present in wetlands, but their functional role there is not well understood. We have quantified the carbon (C) allocation from rice to AMF under different flooding regimes, using stable isotope labeling (13CO2), and assessed the potential phosphorus (P) delivery from AMF to rice by profiling the expression of plant and fungal P transporter genes. The

There is an increasing recognition that, although the climate change and biodiversity crises are fundamentally connected, they have been primarily addressed independently and a more integrated global approach is essential to tackle these two global challenges. Nature-based Solutions (NbS) are hailed as a pathway for promoting synergies between the climate change and biodiversity agendas. There are

Bloggpost på nutritionsfakta.se.EAT-Lancetkommissionen lanserade 2019 sin ”the great food transformation”, en modell för hälsosamma matvanor för en växande global befolkning som skulle hålla livsmedelssystemet inom planetens gränser.En uppföljande svensk studie har tagit fram ett eget index för att mäta följsamheten till EAT-Lancetkosten, med en poängsättning som gör det möjligt att se hur väl en

The carbon isotope composition (δ13C) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the δ13C of foraminifera tests. Here more than 1700 δ13C observations of the benthic foraminifera genus Cibicides from late Holocene sediments (δ13CCibnat) are compiled and compared with newly updated estimates of t

The prevailing narrative on the Syrian Civil War attributes it to climate-induced migration resulting from a severe drought, which serves as a central link connecting climate change with the 2011 protests. However, limited research has involved interviews with Syrians, with most studies focusing on drought's meteorological aspects and estimated migrant numbers. Our interdisciplinary study we condu

Recent advances in information technologies and an increased environmental awareness have altered the prerequisites for successful logistics. For companies operating on a global market, inventory control of distribution systems is often an essential part of their logistics planning. In this context, the research objective of this thesis is: To develop exact methods for stochastic inventory control

INTRODUCTION: Health promotion in everyday settings is of great importance for both individual health and organizational sustainability. A settings-based approach emphasizes how social, physical, and organizational contexts shape the conditions for health. Central principles in health promotion are participation, empowerment, and person-centeredness, which emphasize the active role of the person o

Relaxed eddy accumulation (REA) measurements for 14CO2 enable the estimation of fossil fuel (ff) CO2 fluxes in urban areas. This work is based on 252 REA ffCO2 flux measurements conducted on tall towers in the cities of Zurich, Paris, and Munich. The ffCO2 fluxes were compared to net eddy covariance CO2 fluxes to quantify the role of non-fossil (nf) CO2 fluxes. While the measurements in Zurich and

The lack of energy balance closure in Eddy-Covariance (EC) measurements is a well-known, still unresolved challenge in micrometeorology, with energy balance closure (EBC) rates typically ranging between 60% and 80%. While numerous hypotheses have been proposed to explain this imbalance, the relative contributions of neglected energy storage terms, data quality and flux processing options remain in

Fourteen tree-ring chronologies developed from 788 peatland Scots pines sampled at sites in Estonia, Belarus and Sweden were compared for common growth trends and possible links to regional climate dynamics. Several synchronous growth release events were detected, especially during the 1910s, 1930s, and around 1970 and 1990, indicating that hydrological shifts and associated tree growth responses

In this article, I examine the contradictions and tensions in Colombia's simultaneous embrace of REDD+ and a peace-building process premised on continued extractivism. Colombia is emerging from an internal conflict that lasted more than 50 years. In this process rural land-use is being transformed, generating new conflicts over land use and control with detrimental effects on Colombia's forests. B

Forests are pivotal for biodiversity, food webs, and human economies, and as carbon sinks their climate change mitigation potential is undisputed. However, whether trees continue to efficiently accumulate biomass at an increasing rate with age, how growth trajectories respond to climate change, and vary with latitude at species range margins is under debate. Here, we combine tree-ring data with bi
