Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt

Begreppet segregation har under senare år tagit allt större plats i samhällsdebatten i Sverige. De bakomliggande drivande faktorerna för fenomenet är komplexa och svåra att förklara och att förändra bostadsbeståndet genom nybyggnation tar tid. Trots försök från politiskt håll och från stadsplanerare att motverka boendesegregationen i städer har inga bestående förändringar påvisats. Förutom det dirThe concept of segregation has in recent years been a subject of social debate in Sweden. The underlying driving factors for the phenomenon are complex and difficult to derive and changing the housing stock through new construction takes time. Despite attempts by politicians and city planners to counteract housing segregation in cities, no permanent changes have been concluded. A part from the nei

III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a

Introduction: This study evaluated lipid identification using mass spectrometry. Background: Three main modes of acquisition are used in mass spectrometry of lipids; data-independent acquisition (DIA), data-dependent acquisition (DDA) and targeted acquisition. DIA is the most including one, yielding a complete but complex data set, while targeted is the least including one, basing acquisition on

Klimatförändringarna, energikrisen och en ökande efterfrågan på el har uppmärksammat behovet av en hållbar omställning av energisystemet. Havsbaserad vindkraft spelar en viktig roll i denna omställning och förväntas expandera kraftigt globalt, i EU och i Sverige. Samtidigt möter projekt stort lokalt motstånd. Trots att svenskar generellt visar högt stöd för vindkraft så har en majoritet av de senaClimate change, the energy crisis of 2022-2023, and estimations of future electricity demands have stressed the necessity for a rapid transition of the energy system. Offshore wind energy plays an important role in this transition, and is expected to expand considerably on a global level, in the EU and in Sweden. While Swedes show high support of wind energy, a majority of recent projects have bee

As the demand for eco-friendly alternatives to traditional plastics grows, Polyethylene Furanoate (PEF) emerges as a promising solution. Derived from renewable biomass sources, PEF embodies sustainability principles by reducing reliance on finite resources and minimizing environmental impact. PEF is synthesized from 2,5-furandicarboxylic acid (FDCA), a key monomer which upon polymerization has the

Due to the climate crisis we are facing, we can no longer consider current construction methods, which contribute to 40% of global CO₂ emissions, as an alternative to building. Vernacular architecture, in comparison, offers a sustainable alternative. People have experimented with this approach to designing, constructing, and living throughout time. This system essentially stands for maximizing eff

Foton för forskning och framtiden Kan lösningen på ett forskningsproblem vara din smartphone? Om vi frågar grundarna till projektet CoastSnap är svaret ja! CoastSnap är ett så kallat medborgarforskningsprojekt, vilket innebär att allmänheten deltar i forskning genom att hjälpa till med datainsamling. Kusten är ett utmanande forskningsområde, och i och med klimatförändringarna och den stigande havThe coast is an ever-changing environment, and due to climate change, coastal research is becoming more challenging. To detect changes in the coastline, such as erosion, researchers need large amounts of data over long periods of time. Part of the solution could be the citizen science project CoastSnap – a global community beach monitoring program. The aim of this study was to examine factors that

De flesta associerar förmodligen ordet katalysator med bilkatalysatorer där smutsiga avgaser från fordon renas genom att gasen får reagera med syre och därmed bilda mindre skadliga produkter. Så kallade heterogena katalysatorer är ofta metalloxider och de används i många industrier för att möjliggöra kemiska reaktioner. Ett sådant exempel är Formox-processen, där en katalysator bestående av järnmoIn the Formox-process, methanol is converted to formaldehyde via partial oxidation on a heterogeneous iron-molybdate catalyst. To an extent, the formed formaldehyde (FA) is over-oxidized into carbon monoxide (CO) which cannot be recycled into FA. As CO affects the environment negatively and decreases the process economy, internal attempts have previously been made to decrease the CO formation of t

Cities today globally face significant problems in the context of the climate crisis. Firstly, in terms of resilience in enduring future challenges – urban heat islands, increasingly frequent flooding, supply chain disruptions, sea level rise among others. Secondly, in terms of contributing to said crisis, through carbon emissions, the erosion of biodiversity through sprawl, overconsumption, and c

Låneförbuden i den svenska aktiebolagslagen (ABL) utgör kapitalskydds-regler och innefattar två separata förbudsbestämmelser. Först, ett generellt låneförbud, ofta benämnt som förbudet mot närståendelån, som specificeras i 21 kap. 1§ ABL. Detta förbud hindrar aktiebolag från att låna ut pengar till exempelvis styrelsemedlemmar, aktieägare i bolaget, eller andra bolag inom samma koncern. För det anThe loan prohibitions in the Swedish Aktiebolagslagen (ABL) constitute capital protection rules and mainly encompass two separate prohibition provisions. First, a general loan prohibition, often referred to as the prohibi-tion against loans to related parties (närståendelåneförbudet), which is specified in ABL chapter 21, section 1. This prohibition prevents Swedish limited companies (Sw. aktiebol

Både Sveriges rättsväsende och makthavare gjorde avsteg från gällande processrätt på 1600-talet. Den samtida lagstiftningen uppställde stränga regler för rättegången, bevisvärderingen och straffen. Trolldom hade utgjort ett brott enligt lagstiftningen sedan medeltiden. Med förändringar inom rättsväsendet utökades brottet, samtidigt som anklagelser om Blåkullafärder och djävulspakter spred sig övBoth the Swedish Judiciary and rulers made deviations from applicable procedural law in the 17th century. The contemporary legislation set up strict rules for the trial, the evaluation of evidence, and the punishment. Sorcery had constituted a criminal offense according to the law since the Middle Ages. With changes within the Judiciary, the crime was expanded, while accusations of journeys to Bl

For those who experience development-induced displacement and involuntary resettlement, they have to confront a range of adverse consequences, including the impoverishment risks, lifestyle and livelihood changes, and the precarity brought by asymmetrical power relations. Based on a case study of the Three Gorges Project (TGP), this research investigates the role of state law in shaping the identit

Drainage of peatlands causes changes in water table (WT), vegetation and decomposer community. As a consequence, decomposition patterns and carbon dynamics change, which is visible in altered Dissolved Organic Carbon (DOC) concentrations in ground and soil water. Additional changes in precipitation patterns towards more extreme drought and rain periods, as expected with climate change, cause furth

Forest ecosystems are important actors in climate change mitigation strategies through their abilities to act as both carbon sinks and sources. The commonly used forest management strategy of clearcutting has been suggested to be paired with large greenhouse gas emissions, increasing the need for research on the climate effect from alternative management strategies. Rumperöd forest is managed thro

This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin

Bacterial cellulose (BC) is a versatile and biocompatible polysaccharide produced by bacteria, with Komagataeibacter xylinus being the model species for its production. This polymer has unique properties that make it valuable in several applications, including as a rheology modifier in cosmetics. Cellugy, a Danish start-up, produces EcoFLEXY, a BC-based rheology modifier that enhances the viscosit
