An empirical ignition delay correlation allowing cetane number rating in a production compression ignition engine

This work presents an alternative cetane rating method using a production compression ignition (CI) engine, offering an accessible approach for preliminary fuel evaluation without the need for specialized equipment. As part of this work, an empirical correlation was developed linking ignition delay (ID) to both the cetane number (CN) and intake oxygen concentration. The test method follows the pri

The prefabricated gift : 300 Swedish houses in Bornholm

From June to November 1945, over 70 shipments of flat-packed architectural elements arrived at the harbours of Nexø and Rønne on the Danish island Bornholm. The shipments consisted of prefabricated interior fixtures and ready-to-be mounted walls. The Danish municipality prepared infrastructure, named new roads, and within a year, 300 wooden houses were assembled on site.

Art and Memorialization of Cultural Trauma. The Case of Utöya, Norway.

This paper takes its point of departure in the planned, but later stopped, memorial over the Utöya massacre in Norway. The suggested memorial called Memory Wound was designed by Swedish artist Jonas Dahlberg and would in reality become two memorials, one at Utöya and one in Olso. Examining the debate that eventually led to the cancellation of the planned memorial project, the paper raises question

Substantial continental temperature rise over the Paleocene-Eocene Thermal Maximum in the Pyrenees

The Eocene period experienced several hyperthermal events with the Paleocene-Eocene Thermal Maximum being the most significant. During this event, global mean surface temperatures were 5–6 °C higher and latitudinal temperature gradients were reduced compared to the late Paleocene. Unlike marine temperature records, terrestrial archives are limited, posing challenges for testing climate model compe

IDH1-mutant preleukemic hematopoietic stem cells can be eliminated by inhibition of oxidative phosphorylation

Rare preleukemic hematopoietic stem cells (pHSC) harboring only the initiating mutations can be detected at the time of acute myeloid leukemia (AML) diagnosis. pHSCs are the origin of leukemia and a potential reservoir for relapse. Using primary human samples and gene editing to model isocitrate dehydrogenase 1 (IDH1) mutant pHSCs, we show epigenetic, transcriptional, and metabolic differences bet

Comparing non-ischaemic heart preservation (NIHP) with ischaemic static cold storage of donor hearts in adult cardiac transplantation : study protocol for a randomised controlled trial

Introduction Ischaemia-reperfusion (I/R) injury remains a major challenge in heart transplantation, with mortality risk increasing significantly when allograft ischaemic time exceeds 4 hours. Non-ischaemic heart preservation (NIHP), using continuous hypothermic perfusion, has shown promise in preliminary studies for reducing I/R injury and improving outcomes. This randomised controlled trial aims

The relationship between lifestyle factors and outcome of treatment with TNFα inhibitors in axial spondyloarthritis – results from 14 European countries

Objectives: To quantify the influence of lifestyle factors on tumour necrosis factor inhibitor (TNFi) treatment response, in axial spondyloarthritis (axSpA). Methods: Data on biologics-naïve adults with axSpA were captured from European rheumatology registries. Information on lifestyle factors (smoking, overweight/obesity, and/or alcohol consumption) were identified ± 30 days of commencing their f

On the Prime Number Theorem

The main subject of this thesis is the proof of the Prime Number Theorem. It revolves around the Riemann zeta function, whose continuation to a meromorphic function in the complex plane is discussed. We employ auxiliary functions, including the Chebyshev function, to simplify the proof of the theorem to showing an equivalent statement.

Penicillin V as first-line treatment of pneumonia in primary care : a registry-based study

OBJECTIVES: Penicillin V (PcV) is considered the first-line treatment for community-acquired pneumonia in Scandinavian countries, although data supporting this recommendation are scarce. Thus, this study aimed to compare PcV and amoxicillin regarding the risk of treatment failures in children aged >5 years and adults treated for pneumonia in primary care.METHODS: In this retrospective study of hea

The low and high coverage adsorption structure of CO on unreconstructed Ir(100)-(1×1)

The investigation of carbon monoxide (CO) adsorption on the unreconstructed Ir(100)-(1 × 1) surface under ultra-high vacuum (UHV) conditions is studied with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and high-resolution core-level spectroscopy (HRCLS). At a low coverage of 0.5 ML (monolayer), CO molecules adopt a previously documented c(2 × 2) structure, having CO

3D-Printed Boron-Nitrogen Doped Carbon Electrodes for Sustainable Wastewater Treatment via MPECVD

A novel approach combining 3D printing, phase inversion, and microwave plasma-enhanced chemical vapor deposition is presented. This technique enables the creation of carbon-based electrodes with precise micro- and nanoscale control, offering potential for sustainable and high-performance wastewater treatment applications. The synthesized 3D carbon scaffolds, enriched with B,N-doped carbon nanostru

Barriers to district heating deployment : insights from literature and experts

Over the last century, district heating (DH) has only achieved global market shares of around 10 %. To reach its potential market shares of 25–50 % in Europe by 2050, growth must drastically accelerate. But deployment of DH is hindered by barriers, potentially slowing this fast-paced transition of the heat system. In this paper, we identify barriers to the deployment of DH through manual and GPT-a

U-Pb ID-TIMS baddeleyite age and geochemistry of the newly identified ca. 1.94 Ga magmatic event in the Central-Western Bastar craton

A NNW-trending mafic dyke from the central-western Bastar craton yields a U[sbnd]Pb ID-TIMS baddeleyite age of 1944 ± 6 Ma. By correlating additional dykes with similar trend and geochemical characteristics, we identify a previously unrecognized dyke swarm, named herein the Pakhanjore swarm. Geochemical evidence suggests that the studied rocks are derived from partial melting of a spinel-rich, sha

Algorithm and ninhydrin method allow for measurement of the postprandial appearance of peptides in blood

The recognition of amine groups by ninhydrin, along with a simple mathematical algorithm, showed that di- and tripeptides derived from dietary protein are the major end products of protein digestion entering the blood postprandially. There are thousands of oligopeptides appearing in the gut during protein digestion. However, the presented study on a pig model clearly shows that peptides longer tha

Upprätthållande av våldet?

Syftet med studien är att studera hur svensk domstol resonerar gällande partnervåld i vårdnadstvister via tematisk analys. Studien utgår från ett genusrättsvetenskapligt förhållningssätt och försöker därmed förklara studiens resultat enligt genusrättsvetenskapen och tidigare genusforskning. Studiens empiriska material består av slumpmässigt utvalda domar gällande vårdnadstvister som präglas av par

Revisiting Value Configurations : A Multi-Dimensional Framework for Hybrid Forms and Transition Analysis

Stabell and Fjeldstad (1998) proposed three value configurations; the value shop, the value chain and the value network based on Thompson’s (1967) three technologies as a typology. However, that Thompson’s technologies constitute a typology has been criticized (cf Barbini and Neri, 2017). Also, research has highlighted increased shifts in value configurations and hybrid forms. Thus, the question a

Near-Memory Computing Architectures for Scalable Edge AI Applications

Artificial intelligence (AI) and machine learning (ML) are rapidly permeating nearly every aspect of modern life, frompersonal devices and autonomous systems to industrial automation and environmental monitoring. The growing demandfor intelligence at the network edge is reshaping how computing hardware is conceived and built. Edge AI platforms areexpected to deliver high throughput within tight en

Neutrophil infiltration in peritoneal metastasis affects prognosis in patients with ovarian cancer

The impact on prognosis of neutrophil infiltration in the microenvironment of ovarian cancer remains to be elucidated. In this study, we analyzed the association between neutrophil infiltration in peritoneal metastasis and prognosis. Furthermore, we analyzed the correlation between neutrophil infiltration in peritoneal metastasis and the number of peripheral blood neutrophils, the degree of neutro
