Pedagogisk bruk av digital teknologi som tema i barnehagelærerutdanningen: Hvordan integrerer faglærerne temaet, og hvorfor?

Digital teknologi har blitt en del av barns hverdag, også i barnehagen. For å kunne møte dette på en profesjonsfaglig god måte er det viktig at barnehagelærerstudenter får kunnskap om og erfaring med hvordan digital teknologi kan brukes sammen med barn, i løpet av utdanningen. Fo...

Signs of power: giant ficron handaxes may have played a non-utilitarian role in structuring social groups in MIS 9 Britain

Giant ficrons are a rare but recurrent sub-type of Acheulean handaxe, that in Britain are predominantly found in assemblages dating to the MIS 9 interglacial. A variety of theories have aimed to explain the striking size and appearance of giant ficrons as reflecting their use in...

A single-switch quadratic DC–DC converter with ultra-high voltage gain and low voltage stress on semiconductors

This study offers a single-switch ultra-high step-up DC–DC converter based on the quadratic configuration. In the proposed topology, the quadratic structure is integrated with an auxiliary circuit employing a three-winding coupled inductor. The converter obtains an enhanced volta...

Fatigue strength evaluation of flush-ground butt welded S355 girth welds in close proximity

The fatigue performance of welded tubular structures is a critical consideration in offshore and structural steel applications subjected to cyclic loading. While flush-ground one-sided butt welds are known to improve fatigue life, current design standards primarily provide guidan...

Nebulized lidocaine for preventing postoperative pulmonary complications in major abdominal surgery

Despite the lung-protective ventilation strategy, high incidence of postoperative pulmonary complications (PPCs) after major non-cardiac surgery remains a major concern in the perioperative care due to high morbidity and mortality. The study aimed to evaluate the efficacy and saf...

Consent architecture in biobanking: ethical attitudes and consent preferences among people with cancer and caregivers

Ethical and socially accountable biobanking depends on public trust and informed consent. Understanding how people with cancer and caregivers view biospecimen use is essential for designing consent models that respect autonomy and reflect cultural values. This study examined cons...

High-Temperature service stability of antireflective truncated cone structures

The study addresses the failure of conventional antireflective coatings in high-temperature fighter jet exhaust nozzles by fabricating antireflective truncated cone structures (depth: 260 μm, groove width: 90 μm, period: 140 μm) on GH4099 nickel-based superalloy substrates using...

Students’ Perspectives on the Grade Explanation and Appeal Process in Higher Education in Norway

Students in higher education in Norway have many rights. By law, they can ask for explanations for and/or make an appeal about a grade. The number of explanations requested by students has increased in recent years. This article focuses on explanations and appeals after students...

A low-threshold mechanoluminescence platform for broadband NIR emission and obstruction-penetrating optical communication

Broadband near-infrared (NIR) luminescent materials are highly sought after for next-generation optoelectronics under dim or invisible conditions, yet simultaneously achieving broadband NIR emission, strong low-threshold mechanoluminescence (ML), and self-recoverable mechano-opti...

From behavioural insight to system design: Reframing the role of psychology in public health

Contemporary public health challenges, including non-communicable diseases, persistent inequalities, misinformation, and complex organisational systems, are fundamentally shaped by behavioural, social, and psychological processes. Although this is increasingly recognised, psychol...

Factors affecting adolescent participation in HIV/AIDS prevention services provided by Non-Governmental Organizations in Iran

One of the best ways to reach teenagers with high-risk behaviors and encourage them to use HIV/AIDS prevention services is to seek help from non-governmental organizations (NGOs). Therefore, in Iran, some NGOs active in this field were formed under the name of Adolescent Well-bei...

Multimodal folate receptor-targeted liposomes enable photo-chemo-antibiotic synergy for peritoneal cancer therapy

The complex and heterogeneous nature of cancer presents significant challenges to effective treatment. Because no single therapy can overcome this complex challenge, rational combination strategies that concurrently target tumor survival pathways and engage non-overlapping mechan...

Catalytic valorization of wastewater sludge into aviation fuel-range hydrocarbons over Ni, Cu, Co and ZrO2/SAPO-11 catalysts

This work presents an innovative valorization strategy for wastewater sludge to produce aviation fuel range hydrocarbons via the catalytic processing of esters, using Ni, Cu, Co, and ZrO 2 -based catalysts supported on SAPO-11 zeolite. Biofuel was produced under two reaction atmo...

Comparability of self-reported and accelerometer-based physical activity assessment in patients with facioscapulohumeral muscular dystrophy

Quantifying physical activity (PA) is clinically relevant in facioscapulohumeral muscular dystrophy (FSHD). Wearable accelerometers provide objective measures, whereas self-reported questionnaires are a widely used, cost-effective alternative. However, their comparability in FSHD...

Hybrid rank fusion of a group-token transformer with gradient boosting improves detection of evasive and novel-family malware

Static machine-learning malware detectors report near-perfect closed-set accuracy, but the malware that matters operationally is the malware that slips past detection and the malware that belongs to families never seen in training. We study both on three longitudinal benchmarks:...

Å lære å innovere: veien til økt innovasjonskompetanse i norske kommuner

I artikkelen blir det undersøkt hvordan en praksisnær videreutdanning i innovasjon for kommunalt ansatte bidrar til å utvikle studentenes innovasjonskompetanse. Studien har et kvalitativt, utforskende design og bygger på semistrukturerte dybdeintervjuer av tidligere studenter. Ut...

Predicting corporate culture using machine learning

This study utilizes machine learning (ML) to examine factors that predict corporate culture. Integrating firm financial metrics and nonfinancial factors, we evaluate eight ML models to identify the most effective one for predicting culture and the key factors for cultural values...

Expanding the Clinical Spectrum of ARSACS: An Atypical Adolescent-Onset Presentation with Compound Heterozygous SACS Variants

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare hereditary neurodegenerative disorder caused by biallelic pathogenic variants in SACS.Initially described in the French-Canadian population, ARSACS is now recognized worldwide and ranks among the most co...

Glucosamine and chondroitin sulfate in osteoarthritis: mechanisms, microbiome interactions, and nanotechnology-based advances

Osteoarthritis (OA) is the most prevalent degenerative joint disease worldwide. OA involves chronic pain, subchondral bone remodeling, synovial inflammation, and progressive cartilage degeneration. Gut microbiota (GM) dysbiosis disturbs metabolic processes and systemic inflammati...

Interventricular septal thickness for cardiomyopathic phenotype enrichment in patients with established left ventricular hypertrophy

We evaluated whether interventricular septal thickness in diastole (IVSd) ≥ 15 mm enriches cardiomyopathic phenotypes among adults with established left ventricular hypertrophy (LVH) and whether broader clinical-echocardiographic features improve triage. We studied 1,127 adults u...
