A clear understanding of the mechanisms governing the growth of nanowires is crucial to achieving control over their structures and properties. Here, we employ molecular dynamics (MD) simulations to investigate several important phenomena in Au-catalyzed Si nanowires (SiNWs) grown via the vapor–liquid–solid method. MD simulation serves as a complementary tool for uncovering the mechanisms of nanow
In the aftermath of the Covid-19 pandemic, the accelerated shift to remote and hybrid work modes has left many office buildings vacant. Meanwhile, many cities struggle with providing housing. Adaptive reuse (AR) is the process of giving an existing building a new life, typically through an extensive renovation and refurbishment. Residential adaptative reuse specifically refers to adapting for hous
Purpose: According to most models of spoken word recognition, listeners probabilistically activate a set of lexical candidates, which is incrementally updated as the speech signal unfolds. Speech carries segmental (speech sound) as well as suprasegmental (prosodic) information. The role of the latter in spoken word recognition is less clear. We investi
Introduction: Sport-related concussions (SRC) have been a concern in all sports, including soccer. The long-term effects of soccer-related head injuries are a public health concern. The Concussion in Sport Group (CISG) released a consensus statement in 2017 and several soccer governing associations have published their own SRC guidelines while referring to it but it is unclear whether this has bee
Groundwater contamination is a threat to drinking water resources and ecosystems. Remediation by injection of chemical reagents into the aquifer may be preferred to excavation to reduce cost and environmental footprint. Yet, successful remediation requires complete contact between contamination and reagents. Subsurface heterogeneities are often responsible for diffusion into low-permeable zones, w
The introduction of atomic layer deposition (ALD), to the microelectronics industry has introduced a large number of new possible materials able to be deposited in layers with atomic thickness control. One such material is the high-κ oxide HfO2; thermally stable and ultrathin HfO2 films deposited by ALD are a significant contender to replace SiO2 as the gate oxide in capacitor applications. We pre
Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available to organisms. The detailed mechanism of this enzyme is currently not known, and computational studies are complicated by the fact that different density functional theory (DFT) methods give very different energetic results for calculations involving nitrogenase models. Recently, we designed a [Fe(SH)4H]
Objective: Interactive patient education, referred to as Heart School (HS), is an important part of cardiac rehabilitation (CR) after myocardial infarction (MI), which has been associated with improved outcomes. Little is known about HS attendance among foreign-born patients. The aims were to assess; 1) HS attendance in foreign-born versus native-born patients, 2) the association between the provi
Accurate monitoring of glaciers’ extents and their dynamics is essential for improving our understanding of the impacts of climate and environmental changes in cold regions. The satellite-based Normalized Difference Snow Index (NDSI) has been widely used for mapping snow cover and glaciers around the globe. However, mapping glaciers in snow-covered areas using existing indices remains a challengin
Fibril-reinforced poroviscoelastic material models are considered state-of-the-art in modeling articular cartilage biomechanics. Yet, cartilage material parameters are often based on bovine tissue properties in computational knee joint models, although bovine properties are distinctly different from those of humans. Thus, we aimed to investigate how cartilage mechanical responses are affected in t
Herein, we present the synthesis of two new dicobaloxime complexes, [{ClCo(dmgH)2(4-PyCOO)}2Zn(DMF)2] (1) and [{ClCo(dmgH)2(4-PyCOO)}2Cd(H2O)3(DMF)].4H2O (2) bridged by isonicotinate-Zn(ii) and Cd(ii) moieties. These complexes were synthesized upon reaction of a monomeric chlorocobaloxime [ClCo(dmgH)2(4-PyCOOH)] with Zn(NO3)2·6H2O and Cd(OAc)2·2H2O in a methanol/DMF solvent mixture. Both complexes
Background: Despite improvements in hemophilia care, challenges remain, including treatment burden and impaired quality of life. Gene therapy may overcome these. However, its introduction presents a challenge. Objectives: To outline a function-based gene therapy working model describing critical milestones associated with gene therapy handling, administration, and follow-up to facilitate and imple
Monitoring available feed for livestock is a key factor for developing pastoralism in the Sahel, and satellite images has proven useful in monitoring dry mass on large spatial scales. This approach requires field measurements of dry mass (herbaceous and woody plants) to calibrate such models based on Earth observation data. However, the need for representative field measurements can be a challenge
Introduction: The European corn borer (ECB), Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a major pest insect in maize. New cultivars and climate change have allowed range expansion of the crop northwards in Europe, and a similar range expansion of associated pests has been predicted. ECB exists as two distinct pheromone strains using different blends of (E)-11-tetradecenyl acetate and
Popular Abstract in Swedish I Tallsten barnomsorgs- och skolenhet införde man 1996, som del i en omorganisation av verksamheten, ett nytt tanke- och arbetssätt utifrån en kommunikativ pedagogik. Tre mindre organisatoriska enheter, som var mer eller mindre slutna i förhållande till varandra, slogs samman till en enhet. Ett primärt syfte i sammanhanget var att skapa en helhetssyn på barnet från 1?18This thesis focuses on the pedagogue as a social being and how she or he experiences the social life in preschools and schools in Tallsten. In 1996, the child-care and education authorities in Tallsten introduced a new manner of thinking and working based on the communicative pedagogy. The idea of communicative pedagogy was origanlly put forth by the Danish teacher Lars Rokkjaer. One of the goals
Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning: Miljögift är mat för bakterier i grundvatten Jag har undersökt bakteriers nedbrytning av organiska miljögifter i grundvatten och intresserat mig för hur den påverkas av gifternas vidhäftning till sand och bakteriernas aktivitet och mångfald. Sådan kunskap kan bidra till att förhindra gifters spridning till t.ex. drickvatten. Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. sorption, the presence of dissolved organic matter (DOM), biomass, redox conditions, cometabolism, microbial community composition, and activity of degrading microorganisms, are addressed in the thesis, with the ambition to gain insights for bioremediation in aquifers, and
Popular Abstract in Swedish Tumörimmunologisk grundkurs: En tumörcell har en gång i tiden varit en vanlig laglydig cell i någon av kroppens vävnader men på grund av arv eller dålig uppväxtmiljö så har denna cell upphört att följa de tillväxt begränsande regler som normala celler rättar sig efter. Förutom att kontrollen av celldelningen upphört så kan tumörcellen uppvisa ett mer eller mindre asociThis study aims at clarifying the role of NO in the immunosuppression induced by in vivo tumor growth and by tumor immunotherapy, and determining whether the inhibition of NO production can be used as an adjuvant in tumor immunotherapy. We have shown previously that tumor cells, glioma (N32) and colon carcinoma (H1D2), when genetically engineered to express such immune stimulatory cytokines as IFN
