Hybrid coastal protection systems combine hard and soft design elements and are increasingly utilized to address coastal erosion and flood risks. However, limited data are available on the performance of hybrid structures under extreme storm conditions, and the interactions at the transition between hard and soft elements are not well understood. This study investigates the performance of a hybrid
We investigate proton sharing in biologically relevant polycarboxylic acids in aqueous solutions using liquid-jet X-ray photoelectron spectroscopy. In contrast to techniques that record time-averaged proton positions, like nuclear magnetic resonance, photoelectron spectroscopy captures instantaneous proton distribution due to its ultrafast probing time scale. The method is, therefore, uniquely sen
Spiral galaxies, like the Milky Way, transform at some point in time into a rotationally supported system. Using an extant dataset consisting of 319,835 subgiants from LAMOST with precise ages from the literature, we determine, for the first time, the age when the Milky Way disk spins up, i.e., when the mean circular velocity changes from halo-like to disk-like. We find in concordance previous stu
Ecdysozoa (molting animals) represent one of the most diverse and ecologically successful animal groups in both extant and fossil ecosystems. This study presents new microfossil cuticular evidence from the lower Cambrian (∼535 Ma) Yanjiahe Formation (southern China) for ecdysozoan diversity during the Fortunian Stage. Six forms are recognized mainly based on their ornamented cuticular patterns, as
Fractures pose a significant burden on society, making prevention strategies important. One approach is to increase physical activity (PA), which may enhance bone mass and muscle strength, thereby lowering fracture risk. A total of 3476 children who began 1st grade (mean age 7 years) between 1998 and 2012 in four Swedish schools were included. The intervention group was 1328 children from one scho
The 15-minute city concept has gained prominence in urban planning as a framework linking proximity, mobility, and quality of life at the intra-urban scale. An open question is whether this concept remains meaningful when applied to spatially connected urban regions or national urban systems. To address this issue, the new X-minute city concept allows proximity thresholds to vary with spatial cont
Botanikdagarna har organiserats av Svenska Botaniska Föreningen (SBF) sedan 1979 och är ett tillfälle för botanister i hela landet att mötas och få se arter speciella för ett visst landskap. Förra året hölls de i Blekinge och deltagarna kunde få ta del av miljöer och arter från större delen, eftersom det är ett så litet landskap. Eftersom det är ett ganska dyrt evenemang och antalet deltagare har
Wireless communication systems like Wi-Fi and 5G rely on radio waves whose behavior is difficult to interpret in indoor environments without spatial context. Raw channel measurements processed by parameter estimation algorithms like Space-Alternating Generalized Expectation-Maximization (SAGE) extract multipath components described by their angle of arrival, propagation delay, and attenuation. How
Denna kvalitativa studie undersöker hur visstidsanställda skådespelare vid svenska institutionsteatrar upplever och navigerar yrkets arbetsvillkor, samt vilka mekanismer som bidrar till att dessa villkor reproduceras. Studien bygger på intervjuer med skådespelare samt en facklig ombudsman och analyseras med hjälp av teorier om sociala fält, kapital, prekaritet och emotionellt arbete. Resultatet be
Den 1 juli 2026 förväntas Kriminalvården stå klara med barn- och ungdomsavdelningar för unga lagöverträdare i åldern 13–17 år. Syftet med denna studie är således att undersöka kriminalpolitiska dokument vad gäller unga lagöverträdare och inrättandet av ungdomsfängelser i Sverige. Studien ämnar att belysa, genom en kritisk diskursanalys i linje med Faircloughs (2012 & 2018) tredimensionella mod
Tuvalu, a sovereign island state in the Pacific, faces an unprecedented threat: entering a condition of uninhabitability and losing its land territory due to sea-level rise (SLR). While its inhabitants fight passionately to preserve their home, their remarkable culture, and statehood, existing scientific and legal frameworks remain fragmented to address the situation. The thesis aimed to develop a
Klimatförändringar leder till en ökad mängd nederbörd, vilket medför betydande utmaningar i urbana miljöer. Regnbäddar, en typ av blågrön lösning, kan implementeras för att bidra till hållbar dagvattenhantering genom att rena och fördröja dagvatten. Detta arbete baseras på en fallstudie på regnbäddarna längs Neptunigatan i Malmö, Sverige. Studien innefattade bland annat att utvärdera implementerinClimate change is expected to increase the frequency of heavy rain events, resulting in major challenges for stormwater management in urban areas. Raingardens, a type of blue-green solution, are a sustainable alternative for stormwater management, which can retain and treat stormwater. This master’s thesis is based on a case study of the raingardens along Neptunigatan in Malmö, Sweden and aims to
This study examines how Indonesia’s networked emergency response system performed during the first 72 hours of the Cyclone Senyar disaster in Aceh and what conditions influenced its reliability. Guided by a high-reliability network (HRN) perspective, this research investigates how coordination and collective capacity shape the system’s ability to maintain performance under extreme time pressure an
The maritime industry is undergoing a transition towards alternative fuels to reduce greenhouse gas emissions. These fuels influence engine exhaust gas characteristics and consequently affect the performance of waste heat recovery (WHR) systems. This study investigates the impact of fuel type on the recoverable exhaust gas exergy of marine two-stroke engines and evaluates the suitability of differ
Bakgrund: Hälso- och sjukvården drabbas hårt vid väpnade konflikter. Sjuksköterskor har en avgörande roll i hälso- och sjukvården och riskerar att oförberedda hamna i allvarliga situationer. Syfte: Sammanställa och beskriva sjuksköterskors upplevelser av omvårdnad i samband med väpnade konflikter. Metod: Icke-systematisk litteraturstudie baserad på tio kvalitativa studier som analyserats genom int
This master’s thesis was done in collaboration with Thule Group during the spring of 2026. The purpose was to perform a concept development process in Child Restraint Systems (CRS), more commonly known as child car seats. These products are strictly related to crash safety as well as child ergonomics. Therefore, installations of CRS are important to ensure correct system status, meaning that the p
