The results from a new numerical method for simulating the strength and fracture locations of small glass specimens subjected to double ring bending are compared with experimental data. The method implements the weakest-link principle while assuming the existence of Griffith flaws. A Weibull distribution for the strength is simulated based on a single population of Pareto distributed crack sizes.
This article presents the results of a study of the Swedish multi-family housing stock in relation to its daylight performance under overcast sky conditions. A total of 8573 rooms in 35 existing buildings were investigated using advanced lighting simulations to determine their point daylight factor, as defined in the current building regulations. The buildings were selected based on their architec
Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. The first is that it can be unhygienic since the food is easily contaminated by pests, dust or micro
Purpose: Liquid biopsy has great potential to improve the management of brain tumor patients at high risk of surgery-associated complications. Here, the aim was to explore plasma extracellular vesicle (plEV) immunoprofiling as a tool for noninvasive diagnosis of glioma.Experimental Design: PlEV isolation and analysis were optimized using advanced mass spectrometry, nanoparticle tracking analysis,
Accurate knowledge about the amount and dynamics of terrestrial gross primary productivity is an important component for understanding of ecosystem functioning and processes. Recently a new diagnostic model, Southampton Carbon Flux (SCARF), was developed to predict terrestrial gross primary productivity at regional to global scale based on a chlorophyll index derived from MERIS data. The model aim
Att kunna cykla ses som närmast självklart i Sverige. Den som inte kan avviker från normen och från föreställningen om vilka kunskaper och kompetenser en vuxen människa förväntas ha. Att inte kunna cykla blir också ett problem för individen som riskerar att begränsas och utestängas. Intresset för cykelkurser är därför stort. I denna rapport om Cykelfrämjandets projekt Frihet på cykel undersöks för
Avsaknaden av en teknisk utbildning på mellannivå framstod i mitten av 1800-talet som såväl ett industrialiserings- som ett moderniseringshinder. Som svar på dessa problem etablerades tekniska elementarskolor under 1850-talet i Malmö, Borås, Örebro och Norrköping. Föreliggande artikel behandlar de viktigaste faktorerna bakom lokaliseringen av dessa skolor och svarar på frågorna varför de förlades
The aim of this study was to describe and analyse structural frames for choice, as well as characteristics of a free-choice market, implemented in community mental health services in Sweden. Day centres were focused. A case study was conducted. Documents were collected and semi-structured interviews were conducted with twenty-eight agents involved in the implementation process. Content analysis of
EU har sedan 2013 begränsat användningen av tre neonikotinoider i grödor som är attraktiva för bin. En stor del av den kunskap vi har idag om hur bin påverkas av neonikotinoider kommer från laboratoriestudier av framförallt honungsbin som har matats med växtskyddsmedel. I ett forskningsprojekt har forskare från Lunds universitet och SLU i samarbete med Jordbruksverket undersökt hur ett växtskyddsm
Aim: There is a growing number of older people (65+) with dementia, and many family care partners are involved in making help-seeking choices. The aim of this study was to reveal how family care partners with an old relative with dementia proceed in the name of dignity in their desire to secure the best care possible while still maintaining their own dignity. Methods: Data were collected in 2009–2
In this work, we propose a modified phase-field model for simulating the evolution of mixed mode fractures and compressive driven fractures in porous artificial rocks. For the purpose of validation, the behaviour of artificial rock samples, with either a single or double saw cuts, under uniaxial plane strain compression has been numerically simulated. The simulated results are compared to experime
In the Gram-positive Firmicute bacterium Bacillus subtilis, amino acid starvation induces synthesis of the alarmone (p)ppGpp by the RelA/SpoT Homolog factor Rel. This bifunctional enzyme is capable of both synthesizing and hydrolysing (p)ppGpp. To detect amino acid deficiency, Rel monitors the aminoacylation status of the ribosomal A-site tRNA by directly inspecting the tRNA's CCA end. Here we dis
Insect odorant receptor (OR) genes are routinely expressed in Human Embryonic Kidney (HEK) 293 cells for functional characterization (“de-orphanization”) using transient or stable expression. However, progress in this research field has been hampered because some insect ORs are not functional in this system, which may be due to insufficient protein levels. We investigated whether codon optimizatio
