We need clean drinking water, but current water purification methods are not always sufficient. This study examines the binding and binding mechanisms when graphene oxide is used as a filter material for removing perfluorinated substances and trihalomethanes. We use density functional theory calculations to examine the binding of the harmful molecules on graphene oxide. Our results indicate that t

Despite low-sequence homology, the intermediate filament (IF)-like protein FilP from Streptomyces coelicolor displays structural and biochemical similarities to the metazoan nuclear IF lamin. FilP, like IF proteins, is composed of central coiled-coil domains interrupted by short linkers and flanked by head and tail domains. FilP polymerizes into repetitive filament bundles with paracrystalline pro

Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all f

Increasing impacts from disasters and climate hazards have prompted international efforts to promote the development of national disaster risk reduction and resilience (DRRR) strategies intended to reduce mortality and other losses. The development of such strategies is the subject of target E of the Sendai Framework for Disaster Risk Reduction (2015–2030). Furthermore, an increasing understanding

Sweden's fix of its banks in the early 1990s is considered a model for today’s policymakers. This column reviews the main features of the Swedish approach and discusses its applicability to today’s banking problems. Policy must be carried out swiftly and openly, aiming at saving banks, not their owners or managers.

The antimicrobial peptide LL-37 is active against oral bacteria and has been demonstrated to be present in human saliva, but its distribution in different fractions of saliva is not known. LL-37 is formed from its intracellular pro-form, hCAP18, in an extracellular enzymatic reaction catalyzed by proteinase 3 and kallikrein 5. Here, we prepared cell-containing and cell-free fractions of unstimulat

OBJECTIVE: Recent in vivo results have shown prominent tissue sparing effect of radiotherapy with ultra-high dose rates (FLASH) compared to conventional dose rates (CONV). Oxygen depletion has been proposed as the underlying mechanism, but in vitro data to support this have been lacking. The aim of the current study was to compare FLASH to CONV irradiation under different oxygen concentrations in

Orchids have minute, air-filled seeds and are considered as efficient dispersers and colonizers. Yet, empirical studies show that most seeds fall within the nearest metre from the mother plant in orchids, and that individuals standing close to each other are often closely related. A poor contribution to gene dispersal by seeds may be compensated for by more efficient dispersal by pollen, but in auOrchids have minute, air-filled seeds and are considered to be efficient dispersers and colonizers.

Some lactic acid bacteria, especially Lactobacillus spp., possess adhesive properties enabling colonization of the human gastrointestinal tract. Two probiotic Lactobacillus plantarum strains, WCSF1 and 299v, display highly different mannose-specific adhesion, with L. plantarum 299v being superior to L. plantarum WCFS1 based on a yeast agglutination assay. A straightforward correlation between the

This Letter presents a search for the production of a long-lived neutral particle (Zd) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate scalar boson, where Z→+ (=e, μ). The data used were collected by the ATLAS detector during 2015 and 2016 pp collisions with a center-of-mass energy of s=13 TeV at the Large Hadron Collid

Astrocytes support normal brain function, but may also contribute to neurodegeneration when they become reactive under pathological conditions such as stroke. However, the molecular underpinnings of this context‐dependent interplay between beneficial and detrimental properties in reactive astrogliosis have remained incompletely understood. Therefore, using the RiboTag technique, we immunopurified

I bokens tredje kapitel analyserar Stefan Larsson etiska riktlinjer som styrmedel för utveckling och användning av artificiell intelligens (ai). Författaren pekar på riktlinjernas samspel med rättsliga styrmedel och undersöker vad det är med AI-utvecklingen som särart som lett till att etiska frågor fått en så framskjutande plats med en sådan bred flora av riktlinjer. Genom att anlägga ett europei

Seed dormancy is considered to be an adaptive strategy in seasonal and/or unpredictable environments because it prevents germination during climatically favorable periods that are too short for seedling establishment. Tropical dry forests are seasonal environments where seed dormancy may play an important role in plant resilience and resistance to changing precipitation patterns. We studied the ge

All five accepted Swedish (and Scandinavian) species of the ’Depilata group’, now referred to Hieracium sect. Pulmonarioidea have been revised and a diagnostic key as well as descriptions and illustrations are provided. The geographic distribution of the species in Sweden is mapped, but it is noted that none of them has been collected since 1922. Lectotypes are designated for H. depilatiforme Dahl

Goal-directed behavior can benefit from proactive adjustments of cognitive control that occur in anticipation of forthcoming cognitive control demands (CCD). Predictions of forthcoming CCD are thought to depend on learning and memory in two ways: First, through direct experience, associative encoding may link previously experienced CCD to its triggering item, such that subsequent encounters with t

I denna uppsats efterforskas svar på frågan om hur körledare gör för att lära ut körmusik på gehör. Inledningsvis presenteras tidigare studier som berör körlivet i Sverige samt gehörsinstuderingen i kör. Den teoretiska basen utgår ifrån sociokulturell teori, i synnerhet det sociala samspelet. I teorikapitlets avslutande del introduceras den didaktiska triangeln och begreppet distribuerade resurser
