The chemical compositions of stellar atmospheres reflect the interstellar gas from which they formed, each one containing a snapshot of the Milky Way Galaxy's chemical evolution. By comparing abundances of stars across the disk of our Galaxy, we can explore how different parts of the Galaxy were enriched, where star formation proceeded most rapidly, and whether there has been significant mixing of
Background and purpose: Angiosarcoma (AS), a rare and highly malignant tumour, can manifest spontaneously (primary AS, pAS) or secondary to previous radiation, exposure to chemical agents or Stewart-Treves syndrome (secondary AS, sAS). The aim of this study was to characterise the clinical presentation, management, treatment and outcome—including local recurrence, metastasis and overall survival—a
Loess-palaeosol sequences (LPS) are among the most continuous terrestrial archives of Quaternary climate change. Their widespread distribution, high accumulation potential, and sensitivity to environmental variability make them critical for reconstructing past dust fluxes, wind regimes, and regional ecosystem responses. However, the reliability of such reconstructions is fundamentally constrained
This editorial introduces the special feature’s main objective: to provide latest research findings on the dynamics between environmental protection and post-conflict peacebuilding processes after internal armed conflicts. In the feature, we propose a broad understanding of environmental peacebuilding that takes all cycles of the peacebuilding process into account and puts stronger emphasis on the
This paper examines the relationship between environmental accidents and voting. Following the 1986 Chernobyl disaster, environmentalist parties entered parliaments in several nations. This paper uses Chernobyl as a natural experiment creating variation in radioactive fallout exposure over Sweden. I match municipality-level data on cesium ground contamination with election results for the environm
Spring water, however, is often formed in complex geological formations and therefore it is difficult to determine the catchment area contributing to the flow. The Sayanokami spring, located in western part of Fukuoka City, Japan, is such a spring and an important water resource for the local agriculture. In order to better understand the hydrological properties of infiltration and groundwater pro
Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust i
Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limit
While a bottom-up approach to identifying problems affecting food production among small-scale farmers has been urged as an appropriate means of finding sustainable solutions, few studies have determined the practical process of doing so and measured the outcomes of such an approach. This paper uses information gained mainly through focus groups with small-scale farmers and semi-structured intervi

The industrial food production system have given rise to tens of thousands of local, national and international social movements concerned with food and agriculture, reacting to the perceived social and environmental failures of the industrial food system. One of the directions inside these movements is the internationally based “local food” movement. The ”local food” movement promotes small-scal
In the summer of 2013, devastating floods caused heavy damage along various streams in central Europe. In the river basin Eferding in Austria, the Danube River reached record water levels and flooded hundreds of homes in the low-lying areas over night. The response of the government to resettle people has been heavily criticized by a local citizen initiative, leading to protests in front of the re
The round goby, Neogobius melanostomus, is a recent intruder of the Baltic Sea, which presumably arrived via the ballast water of travelling ships. The establishment of self-sustaining populations in this ecosystem has had both negative and positive effects on the native species composition within the area. Competition over resources and shelter, spawning interference, and the predation on native
Chocaya Basin ligger i den nordvästra delen av dalen Cochabamba i Bolivia, där ett halvtorrt klimat råder. Den ökande befolkningen är beroende av lokala akviferer för dricksvatten och jordbruk, där brunnar används för att utvinna vattnet. Låg nederbörd, främst under torrperioden, och uppförandet av nya hus eller fabriksbyggnader, påverkar infiltrationen av vattnet i jorden och därmed akviferernas The Chocaya Basin is situated in the north-western part of the Valley of Cochabamba, Bolivia, where a semi-arid climate prevails. The increasing population is dependent on local aquifers for drinking water and irrigation. Wells are used to extract water. Scarce amount of rainfall, mainly during the dry season, and constructions of buildings, are reducing the infiltration of water in the soil and c
In Nampula Province, Mozambique, locating productive wells is a problem due to the heterogeneity in local geology, which consists of mainly weathered crystalline rock. This study estimates hydraulic conductivity of 10 hand pumped water wells in rural areas of Nampula Province using slug tests, and is a follow up of Andersson and Björnström (2013) and of Enkel and Sjöstrand (2013).

With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. This thesis considers disordered/ordered inte
This work tackles the challenge of assessment of force distributions in granular media. Spatially resolved neutron and x-ray diffraction are used to measure internal strains of sand grains under load. These approaches are sensitive to the crystallographic strains of the sand grains (quartz crystals) such that each grain acts as a local 3D strain gauge and so, for elastic deformations, a force gaug
