The Colombian peace agreement, which has brought an end to a prolonged internal armed conflict has led to significant land use changes that underscore existing inequalities and struggles over natural resources. The expansion of industries such as cattle ranching, agriculture, and extraction is encroaching on indigenous territories and protected areas, resulting in negative consequences for communi
BackgroundIt remains unclear as to why some individuals at low risk of cardiovascular disease (CVD) develop severe coronary atherosclerosis, while those at high CVD risk may remain free from coronary atherosclerosis.PurposeUsing Coronary Computed Tomography Angiography (CCTA), we aimed to identify factors associated with absence and severe coronary atherosclerosis in subjects from the general popu
Popular Abstract in English Fish are an excellent source of healthy protein and fat in the human nutrition. However, the fisheries cannot supply enough of fish to satisfy the demand of a growing world’s population. Sustainable aquaculture can help feeding the growing world. This business is growing every year, and together with it the fish farms and fish feed factories are growing. This created thAs aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. The Holmen pellet tester (NHP 100) could be adapted for this purpose, but the spec
Popular Abstract in English Popular science Microbial cells are small and difficult to handle in industrial processes, especially if they are to be reused subsequent batches. In order to make them easier to handle, these cells can be attached to a solid support, by so-called immobilization. This provides particles of sizes that are easy to filter and reuse. However, immobilization is associated wiAbstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide
Harvesting of wood for bioenergy purpose will probably increase in importance in the future, in order to replace fossil fuel. However, the environmental impact of increased harvesting might be considerable, e.g. on soil and water chemistry, biodiversity and long-term productivity, and in this study we investigate thresholds for sustainable harvesting volumes. The study is based on scientific revie

The concept of vandalism is analyzed as a symbolic act. An analysis of vandalism from a situational-positivistic, or a motivational-psychological, approach hardly gives an understanding of vandalism as a meaningful individual and social act. A humanistic and cultural perspective can supply ways to understand a nonprescribed behavior such as vandalism. The original meaning of vandalism is plunderin
Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimu
One of the largest sources of uncertainties in modelling of the future global climate is the response of the terrestrial carbon cycle. Studies have shown that it is likely that the extant land sink of carbon will weaken in a warming climate. Should this happen, a larger portion of the annual carbon dioxide emissions will remain in the atmosphere, and further increase global warming, which in turn

Popular Abstract in English Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material.

The scientific knowledge of climate change processes and their worrying future implications for human societies and natural systems has developed considerably during the last decade, but necessary adaptive actions by decision makers have so far been rather limited. There are several causes to this, such as a discrepancy related to the communication between climate scientists and end-users, and the
Popular Abstract in English This thesis concerns experiments of heat transfer in a rectangular channel with ribs and an obstacle. Liquid crystal thermography (LCT) is used to record the temperature fields in the experiments. LCT is based on measurement of the color response of a heated surface. When illuminated with a white light, the liquid crystals react to temperature changes by changing color,This thesis presents experimental investigations of local heat transfer in a rectangular channel (aspect ratio AR = 4) with continuous transverse ribs as well as an obstacle. Liquid crystal thermography (LCT) is employed to obtain the temperature fields in the heat transfer experiments. The liquid crystal applied here has a red start at 35°C and a bandwidth of 1°C. The work consists of (1) periodi
The study presents a hydrology concept developed to include lateral water flow in the biogeochemical model ForSAFE. The hydrology concept was evaluated against data collected at Svartberget in the Vindeln Research Forest in Northern Sweden. The results show that the new concept allows simulation of a saturated and an unsaturated zone in the soil as well as water flow that reaches the stream compar
Europe is one of the world's largest food producers, and climate change may pose a serious threat to food security in the region. In the present study, we assess the potential impact of climate change on the Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say)-a severe pest of potato (Solanum tuberosum, L.). We also investigate the possible impact of climate change on the phenological dev
The leadership literature has been faulted for framing leaders (and followers) as rational and disembodied information processers. This chapter presents a review of studies that go against this tendency by focusing on how materiality, embodiment, and aesthetics are involved in leadership communication. A number of different perspectives are highlighted in relation to the three focal themes, as wel
High latitude mires are key ecosystems in the context of climate change since they store large amounts of carbon while constituting an important natural source of methane (CH4). However, while a growing number of studies have investigated methane fluxes (FCH4) at the plot- (~1 m2) and ecosystem-scale (~0.1–0.5 km2) across the boreal biome, variations of FCH4 magnitudes and drivers at the mesoscale
