New antimicrobial agents are needed to address the ever-growing risk of bacterial resistance, particularly for methicillin- and vancomycin-resistant Staphylococcus aureus (S. aureus). Here, we report a class of bile acid oligomers as facial amphiphilic antimicrobials, which are noncovalently fabricated by cholic acid (CA) and deoxycholic acid (DCA) with polyamines (e.g., diamines, diethylenetriami
The Veiki moraine in northern Sweden, a geomorphologically distinct landscape of ice-walled lake plains, has been interpreted to represent the former margin of an intermediate-sized pre–Last Glacial Maximum (LGM) Fennoscandian ice sheet, but its age is debated as either marine isotope stage (MIS) 5c or MIS 3. We have applied optically stimulated luminescence (OSL) and radiocarbon dating to four si
The widespread use of nanomaterials has raised the threat of nanoparticles (NPs) infection of soils and groundwater resources. This research aims to investigate three parameters including flow velocity, ionic strength (IS), and initial particle concentration effects on transport behavior and retention mechanism of functionalization form of graphene oxide with polyvinylpyrrolidone (GO-PVP). The tra
Northern ecosystems, encompassing boreal forests, tundra, and permafrost areas, are increasingly affected by the amplified impacts of climate change. These ecosystems play a crucial role in determining the global carbon budget. To improve our understanding of carbon uptake in these regions, we evaluate the effectiveness of employing the physically-based Plant Phenology Index (PPI) to estimate gros
Nitrogenase is the only enzyme that can convert N2 into NH3. The reaction requires the addition of eight electrons and protons to the enzyme and the mechanism is normally described by nine states, E0–E8, differing in the number of added electrons. Experimentally, it is known that three or four electrons need to be added before the enzyme can bind N2. We have used combined quantum mechanical and mo
Resolving the spatial and temporal dynamics of gross primary productivity (GPP) of terrestrial ecosystems across different scales remains a challenge. Remote sensing is regarded as the solution to upscale point observations conducted at the ecosystem level, using the eddy covariance (EC) technique, to the landscape and global levels. In addition to traditional vegetation indices, the photochemical
The construction sector has been criticised in recent years for being inefficient. The critique involved describes finished buildings as having flaws and there being a lack of interest within the construction sector in assembling knowledge and sharing experience. The construction industry has started working with questions of how efficiency can be increased by reducing the errors made. Knowledge
A method for simultaneous extraction and quantification Of four non-steroidal anti-inflammatory drugs (NSAIDs) based on continuous flow hollow fiber liquid-phase microextraction (CFHF-LPME) was developed. The effect of sample flow rate, acceptor flow rate, type of acceptor flow (continuous, semi-continuous or forward-backward), type of supported liquid membrane and sample volume was studied. The e
Popular Abstract in Swedish Genetisk information lagras i DNA, som är en mycket stabil molekyl. I våra celler finns samma gener i alla celler. Det är därför av yttersta vikt att uttrycket av generna kan regleras olika i olika vävnader. Bakterier, som är encelliga organismer, måste för att kunna överleva noga kontrollera uttrycket av olika gener beroende på växlingar i omgivningen. Jag har studeratGenetic information, which is stored in DNA, is transferred to messenger RNA (mRNA) in a process called transcription. mRNAs are then translated by ribosomes into proteins which, with some important exceptions, catalyze chemical reactions in cells. Since cells must be able to adapt to changes in the environment, mRNAs must be unstable. The present investigation concerns mRNA degradation mainly in
Wild waterfowl are important reservoir hosts for influenza A virus (IAV) and a potential source of spillover infections in other hosts, including poultry and swine. The emergence of highly pathogenic avian influenza (HPAI) viruses, such as H5N1 and H5N8, and subsequent spread along migratory flyways prompted the initiation of several programs in Europe, North America, and Africa to monitor circula
Background: To determine the feasibility and efficacy of a retinal telephotocoagulation treatment plan for diabetic macular edema. Methods: Prospective, interventional cohort study at two clinical sites. Sixteen eyes of ten subjects with diabetic macular edema underwent navigated focal laser photocoagulation using a novel teleretinal treatment plan. Clinic 1 (King Khaled Eye Specialist Hospital, R
In the present study, one type of uniformly nanostructured surface (NPDS) was modified by electrophoretic deposition. Two kinds of micro/nanostructured surfaces (FLS1 and FLS2) were fabricated on copper surfaces by femtosecond laser processing. The micro/nanostructured surfaces were further modified by electrophoretic deposition. Afterwards, composite micro/nanostructured surfaces (CS1 and CS2) we
Membrane-bound water channels known as aquaporins (AQPs) facilitate water transport across biological membranes along osmotic gradients. Since all living cells depend on their ability to maintain water homeostasis, this must be tightly regulated. In eukaryotes, this is achieved by gating, which involves a conformational change of the protein, thereby physically blocking water transport, or by traf
Timing of return to the breeding area presumably optimizes breeding output in migrants. How timing affects the other components of fitness — survival, has been comparatively little studied. Returning too early in spring is expected to be associated with high mortality in insectivorous migrants when weather conditions are still unsuitable. Yet, males in particular arrive early to get access to the
Objective: To identify reliable predictors of outcome in comatose patients after cardiac arrest using a single routine EEG and standardized interpretation according to the terminology proposed by the American Clinical Neurophysiology Society. Methods: In this cohort study, 4 EEG specialists, blinded to outcome, evaluated prospectively recorded EEGs in the Target Temperature Management trial (TTM t
Detta arbete behandlar medgivandeutredningen (senare benämnd utredningen) av familjehem ur ett rättssäkerhetsperspektiv. Utredningar av familjehem görs utifrån bestämmelser i Socialtjänstlagen (SoL) och det är denna lag som utgör grunden för utredningarna. I arbetet görs därför först en beskrivning och kort genomgång av vad som historiskt föregått den lagstiftning som resulterat i SoL och den raml
Ur FN:s Barnkonvention följer principen om att det som anses vara barnets bästa måste vara avgörande vid alla beslut som rör barn. Konventionen blev svensk lag 1 januari 2020, men har varit en del av svensk rätt längre än så. Sverige ratificerade barnkonventionen år 1990 och sedan dess har principen successivt inkorporerats i svensk lagstiftning. Principen är bland annat en viktig del av skyddslag
The digital platform Airbnb has gained popularity in a number of countries particu- larly in the Maltese islands. Striking a balance in setting a price that is competitive and also renders a good profit can be a challenge. In this thesis a model is de- veloped to predict the price of a listing in the Maltese islands for September 2022 through a machine learning approach whereby five types of model
I Sverige lever tyvärr många barn i hem där uppgifter om våld förekommer. Att umgänge sker mellan ett barn och en våldsutövande förälder riskerar att få allvarliga konsekvenser och är en problematik som existerar bland annat i och med utformningen av lagstiftningen. Därav har regeringen 2025 infört ett per-spektivskifte i föräldrabalken och gjort flertalet lagändringar, en sådan är ut-formningen aIn Sweden many children live in homes where they are at risk of violence from an abusive parent. A relationship that includes direct contact with a vio-lent parent poses a risk of damaging consequences for the child and is an is-sue that exists due to, among other things, the wording of the legislation. Therefore, in 2025 the government introduced a shift in perspective in the Swedish Parental Cod
