Six strains isolated from fermented food were by 16S rDNA sequencing identified as Weissella species, clustering with the species-pair W. confusa/ W. cibaria. The strains were analysed for growth on glucose, xylose and xylooligosaccharides (XOS). All strains were xylose positive using the API CHL 50 test. Growth on XOS was observed for strain 85, 92, 145 and AV1, firstly by optical density measure
Perfluoroalkyl acids (PFAAs) are a large group of chemicals which are highly persistent in both nature and humans. The use of the most prominent ones, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), was reduced in the early 21st century, and since then levels in human matrices have decreased. However, these two compounds have been exchanged by other PFAAs, for which time trends
This paper reports for the first time the application of sol-gel microarrays for immobilizing nonsoluble small chemicals (Bisphenol-A; BPA). Also, known problems of sol-gel adhesion to conventional microtiter well plate substrates are circumvented by anchoring the sol-gel microspots to a porous silion surface so-called, PS-SG chips. We confirmed low molecular weight chemical immobilization inside
The application of detailed chemistry to the computational fluid dynamics simulation of combustion process in diesel engines has many potentials, including the possibility to predict auto-ignition, diffusion flame structure, stabilisation and soot formation in a wide range of operating conditions, also taking into account the effects of different fuel types. Among the approaches that were proposed
In timber-concrete composites (TCC), more researchers are trying to find the “ultimate” shear connector, which combines multiple advantages. Bonded steel plates are one of the possible solutions. This paper provides an analytical and a numerical approach, calibrated with previously conducted experiments, to predict the load carrying capacity, and corresponding governing failure mode, of perfobond
Vegetation demographic models (VDMs) are advanced tools for simulating forest responses to climate and land-use changes, and are essential for projecting carbon cycling and large-scale forest management strategies. Despite their increasing incorporation into Earth System Models, VDMs differ in their demographic assumptions, with no prior quantitative comparison of their performance. We benchmarked
The model is based on an existing framework for high-cycle fatigue by Ottosen et al. (2008) that treats the fatigue damage as a time-continuous variable, opposed to relying on cycle-counting techniques. We propose a generalized formulation where the relationship between the fatigue limits for fully reversed shear stress and normal stress can take any value, unlike in the original formulation, wher
Future-oriented environmental assessments—in particular, prospective life cycle assessments (LCAs)—are increasingly applied within the wastewater treatment (WWT) sector. This thesis contributes to this field of research by addressing how to estimate the environmental impact (improving LCA methodology) and what the impact amounts to (WWT-specific results) for a wastewater treatment plant not yet co
This paper presents a single-layer filtering antenna (filtenna) based on a compact square substrate-integrated waveguide (SIW) cavity for millimeter-wave (mmWave) applications. The cavity operates in the fundamental TE110 mode to enable beam scanning, while a central shorting via introduces the TE210 mode, broadening the bandwidth. A radiating slot, placed at high-intensity regions of both modes,
Peripheral nerve tumours, most commonly schwannomas and neurofibromas, might present significant challenges by eliciting physical symptoms and emotional distress. We aimed to explore patients’ expectations, perceptions, and experiences regarding their diagnosis and the surgical treatment of a nerve tumour in the upper limb. Fourteen adults (10 women, 4 men; age range 35–85) from two Swedish hand s
Proteins and peptides are vital biomolecules, and deuterated amino acids are increasingly applied in areas such as drug discovery, metabolic tracing, and neutron scattering studies. In this study, we performed deuteration on all 20 proteinogenic amino acids, including their side chains, and established efficient methods for 13 amino acids. Using a Pt/C-catalyzed hydrogen–deuterium exchange reactio
The retinoblastoma gene (RB1), which is located on chromosome 13q14.2, is mutated in retinoblastoma (RB), the most common malignant intraocular tumor in children. About 8000 new cases of retinoblastoma are diagnosed globally each year, accounting for approximately 1 in 17,000 live births. RB is prototypically considered hereditary by nature as thirty to forty percent of cases have autosomal domina
The Cherenkov Telescope Array (CTA) is the future observatory for ground-based imaging atmospheric Cherenkov telescopes. Each telescope will provide a snapshot of gamma-ray induced particle showers by capturing the induced Cherenkov emission at ground level. The simulation of such events provides camera images that can be used as training data for convolutional neural networks (CNNs) to differenti
Dopaminergic neurons in the ventral midbrain are critical for regulating movement, cognition, and emotion. Ventral midbrain organoids can be used to model both development and diseases of the dopaminergic system, especially Parkinson’s disease. Here, we summarize recent advances and remaining challenges in developing such three-dimensional organoids from human pluripotent stem cells. We outline ho
This study investigates the neural encoding of speech features in hearing aid users using electroencephalography (EEG) during a simulated cocktail party scenario. The objective was to investigate neural tracking of various acoustic and linguistic features and how hearing aid noise reduction influenced this tracking. The features analyzed included the acoustic envelope, phonetic features, word onse
Neuroblastoma (NB) is a heterogeneous childhood cancer, characterized by the amplification of the MYCN oncogene in 40% of the high-risk cases. Our previous work demonstrated that MYCN drives metabolic reprogramming in NB, including upregulation of antioxidant enzymes. Here, we identify peroxiredoxin 6 (PRDX6) as a promising therapeutic target in NB. Pharmacological inhibition of PRDX6 reduces MYCN
Motivation Efforts to address health disparities are often limited by the lack of robust computational tools for inferring genetic ancestry by calculating an individual's genetic similarity to continental groups. We have already shown that a preferred alternative to self-described race is using ancestry-informative markers (AIMs) that can be classified into ancestral components and used to estimat
Purpose: Developmental language disorder (DLD) has known consequences on academic performance, and adaptations to teaching methods and material are often required to counteract negative outcomes. This study used first-hand reports from students with DLD and their caregivers to explore how individual and school-related factors influence academic achievement and provision of educational support. Met
Soma design is intimately entangled with the politics, not only of design itself, but of bodies. We combine perspectives from soma design, political theory, and Sara Ahmed’s work The Cultural Politics of Emotions, to develop five political provocations that reflect on the politics of soma design and the possibilities and frictions therein. Inspired by soma design’s roots in somaesthetic philosophy
