The non-uniform conditions and potential progression of fires in larger spaces calls for modelling methods extending outside of the traditional compartment fire framework. Even though a handful of studies in the area exist there is still little guidance available on how progressing fires in large enclosures can be modelled. Three different methods to calculate far-field gas temperature in large en
In the Tunisian semiarid area, water erosion processes have led to negative economic and environmental consequences in a context of limited water resources. To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed. The studied small reservoir network displays a gener
The worldwide growing demand for whey proteins and derivatives requires more efficient and sustainable whey protein production processes. Whey is an important by-product from cheese manufacturing. In whey industry membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis are well-established to concentrate, fractionate and purify whey proteins as well as whey
Objective: As digital technologies for health continue to develop, the ability to provide primary care services to patients with new symptoms will grow. In Sweden, two providers of digital primary care have expanded rapidly over the past years giving rise to a heated debate with clear policy implications. The purpose of the study is to present a descriptive review of digital primary care as curren
Coastal systems can act as filters for anthropogenic nutrient input into marine environments. Here, we assess the processes controlling the removal of phosphorus (P) and nitrogen (N) for four sites in the eutrophic Stockholm archipelago. Bottom water concentrations of oxygen (O2) and P are inversely correlated. This is attributed to the seasonal release of P from iron-oxide-bound (Fe-oxidebound) P
Background: As healthcare becomes increasingly complex, new methods are needed to identify weaknesses in the system that could lead to increased risk. Traditionally, the focus for patient safety is to study incident reports and adverse events, but that starting point has been contested with a new era of safety investigations: the analysis of everyday clinical work, and the resilient healthcare. Th
Fire frequency is changing globally and is projected to affect the global carbon cycle and climate. However, uncertainty about how ecosystems respond to decadal changes in fire frequency makes it difficult to predict the effects of altered fire regimes on the carbon cycle; for instance, we do not fully understand the long-term effects of fire on soil carbon and nutrient storage, or whether fire-dr
This is the third annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish
Riksdagen har under hösten 2020 antagit de lagförslag som utarbetats i prop. 2019/20:190 Ekonomiskt arbetsgivarbegrepp – förändrade skatteregler vid tillfälligt arbete i Sverige. Den mest omtalade ändringen avser den s.k. 183-dagarsregeln i SINK och övergången från ett formellt till ett ekonomiskt arbetsgivarbegrepp. I propositionen presenterades det även lagförslag som numera innebär kraftigt ökaThe Swedish parliament adopted during the late autumn of 2020 the law proposals that were suggested by the Swedish government in prop. 2019/20:190 Ekonomiskt arbetsgivarbegrepp – förändrade skatteregler vid tillfälligt arbete i Sverige. The most debated topic has been the changes in the so called 183-day rule in SINK and the transition from a formal to an economic employer approach. In the same bi
Kan energibalansen vid träning påverka benkvalitet? Hur påverkas de små byggstenarna i benet när kroppen får för lite energi men samtidigt utsätts för hård träningsbelastning? Denna studie undersöker hur man kan visualisera både kollagenfibrer samt bencellernas kommunikationsnätverk i benvävnad hos möss med, respektive utan relativ energibrist (RED-S). Relativ energibrist inom idrott (RED-S) uppRelative Energy Deficiency in Sport (RED-S) is a condition arising when dietary energy intake is insufficient to meet the combined demands of training and normal physiological functions. RED-S negatively impacts bone health, and increases the risk of stress fractures. Yet, its effects on bone matrix organization and overall bone quality is not well understood. Collagen and the osteocyte cells'
Tuberculosis (TB), caused by Mycobacterium tuberculosis, remains one of the deadliest infectious diseases worldwide. In 2023, it accounted for approximately 1.25 million deaths, including 161,000 among individuals living with HIV, making it the leading cause of death from a single infectious agent. The growing prevalence of multidrug-resistant TB (MDR-TB) further complicates treatment and contribu
Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. However, regional studies about integration of resource recovery processes at different scales or about the main barriers to implementation in developing countries are missing in the literature
Mathematical models are useful for predicting the reactions of watercourses such as rivers due to the entry of contaminants. Some of these models are able to simulate the effects of present and future loadings as well as aid managers and officials in making decisions even if the data are sparse. In other words, river water quality preservation requires more investment in wastewater treatment and/o
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and biocl
Astrocytes play a crucial role in the onset and progression of amyotrophic lateral sclerosis (ALS), a fatal disorder marked by the degeneration of motor neurons (MNs) in the central nervous system. Although astrocytes in ALS are known to be toxic to MNs, the pathological changes leading to their neurotoxic phenotype remain poorly understood. In this study, we generated human astrocytes from induce
Premise: Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia. Methods: We measured floral traits, reflectance of petals and nectar-guide
HIV-2 is less pathogenic compared to HIV-1. Still, disease progression may develop in aviremic HIV-2 infection, but the driving forces and mechanisms behind such development are unclear. Here, we aimed to reveal the immunophenotypic pattern associated with CD8 T-cell pathology in HIV-2 infection, in relation to viremia and markers of disease progression. The relationships between pathological diff
Generally speaking, Computer based numerical hydrological models have been playing a very central role during the last decades in dealing with water resources related problems. Various kinds of conceptual, physical and stochastical models have been developed. Perhaps the most important contribution of those models is the ability of simplifying and schematizing a complex problem in the nature and s
Popular Abstract in Swedish Wilms tumör eller nefroblastom är en njurtumör som drabbar 10-15 barn i Sverige varje år. Majoriteten av dessa är under sex år vid insjuknandet och 10 % av de som drabbas överlever inte sjukdomen. Tumören består oftast av tre stycken cellkomponenter: blastem, epitel och stroma. Dessa komponenter kan finnas av olika mängd i tumören. Om en tumör består av mer än 2/3 av nåThe aim of this thesis has been to establish biomarkers for the blastemal element in Wilms tumour (WT) – the most common paediatric kidney cancer. Blastema is, together with epithelium and stroma, one of the three common histological elements of WT. WTs dominated by blastema after preoperative chemotherapy are classified as high risk tumours. According to the SIOP2001 protocol used in most Europea
Sustainable development is currently said to be an overriding development goal, also for development assistance. It requires new approaches that challenge not only economic rationality but also bureaucracies in ways that encourage political pluralism and the participation by civil society. As the gap between rich and poor increases and as the pressures on already strained systems constantly increa
