Kämpinge senmedeltida kyrka : Den gotiska labyrinten mellan två kriser

Dateringen för uppförandet av Kämpinge kyrka på Falsterbohalvön var okänd fram till 1987. Det året undersökte lärare och studenter från Lunds universitet byggnaden och kyrkogården. Kyrkan visade sig vara byggd omkring år 1400 och utformad med långhus, kor och tresidigt avslutat kor. Ett sidoaltare vid norra tvärskeppet och ett högaltare dokumenterades, liksom två separata golvnivåer och fundament The construction date for Kämpinge church on the Falsterbo peninsula was unknown until 1987. In that year, teachers and students from Lund University investigated the building and the cemetery. The church was found to be built around 1400 AD and designed with a nave, chancel and three-sided chancel gable. A side altar at the north transept and a high altar were documented, along with two separate

Joint Design of Transmit and Receive Weights for Subarrayed FDA With Partial Prior Knowledge Using Approximated Consensus-ADMM

The distinguishing feature of frequency diverse array (FDA) systems as compared to conventional phased-array and multiple-input multiple-output (MIMO) radar systems is the use of a small frequency offset (FO) across the array elements. Much of the development to date has focused on the FDA-MIMO structure, using an FO that is larger than the bandwidth of the baseband signal, thereby reducing the re

Cross-luminescence in BaF2 crystals doped with M3+ and RE3+ ions : Hybrid density functional theory study

Radiation resistant inorganic materials emitting cross-luminescence are one of the most prospective candidates for new generation ultrafast detectors for medical tomography. Radiative transitions leading to cross-luminescence occur between valence and core states, and therefore calculations of the electronic structure of doped materials can explain ultrafast transitions and predict new cross-lumin

Radiographers’ perspective of patient safety at ultrasound units in radiology departments

Introduction: The radiology department plays an important role in healthcare settings, facilitating diagnoses using different imaging modalities, including ultrasound. However, this high-tech environment can pose various risks to patients. In this study, we aimed to describe the risk of patient safety incidents, and factors associated with the prevention of risks related to ultrasound examinations

Surface of High-Entropy perovskite catalyst La(CoCuFeAlCe)0.2O3 (100) : Experimental study of methanol steam reforming for hydrogen production and DFT mechanism research

High-entropy perovskite catalyst was synthesized and utilized for the first time in the MSR catalytic reaction. Among the HEPs, La(CoCuFeAlCe)0.2O3 exhibited excellent MSR activity and high selectivity. The mechanism of the MSR reaction on the catalyst (100) surface was studied by employing DFT. The results indicate that the surface of La(CoCuFeAlCe)0.2O3 catalyst has the lowest energy barrier, wh

Glimmingehus : Nordens bäst bevarade medeltida borg?

Glimmingehus is a 16th century tower house located in the southeast corner of Scania, Sweden. It is a rectangular stone building with stepped gables whose foundations were laid in 1499, standing three floors high with a basement and an attic. The building is generally presented as ‘the best-preserved medieval manor in Scandinavia’, and in previous research as well as in the public’s view it is fir

Time-Correlated Single-Photon Counting for versatile longitudinal diagnostics at the MAX IV Laboratory storage rings

Precise diagnostic on the electron beam parameters is a very valuable tool and essential in the operation of synchrotron light sources. One possible option is to employ the emitted synchrotron radiation for non-destructive measurements. A tool, which has been used in many ring-based synchrotron light sources is Time-Correlated Single-Photon Counting (TCSPC). It allows to measure the arrival time d

Exploring the potential of perovskite LaBO3 (B = Co, Fe, Cu, Al) as an efficient and durable hydrogen production catalyst for methanol steam reforming : Experimental and DFT studies

In this study, LaBO3 (B = Co, Fe, Cu, Al) perovskite catalysts were introduced for Methanol Steam Reforming (MSR). Results showed that LaCoO3 displayed a 100 % methanol conversion efficiency and a notable hydrogen production rate of 7.86 mol/min/gcat, maintaining stability for more than 40 h at 600 °C. Theoretical computations indicate that the CH3O dehydrogenation to CH2O (a rate-determining proc

Bayesian optimization across the spectrum of knowledge : enhancing efficiency through beliefs, information and assumptions

Bayesian Optimization has emerged as a crucial technique for optimizing costly, black-box functions where each evaluation comes at a high cost, such as in scientific experiments, and machine learning hyperparameter optimization. By combining probabilistic modeling with sequential decision-making, Bayesian Optimization achieves efficient exploration, guiding the search toward optimal parameters wit

Effect of substrate misorientation angle on the structural properties of N-polar GaN grown by hot-wall MOCVD on 4H-SiC(0001̄)

The effects of substrate misorientation angle direction and degree on the structural properties of N-polar GaN grown by a novel multi-step temperature epitaxial approach using hot-wall metal–organic chemical vapor deposition (MOCVD) on 4H-SiC (0001̄) substrates is investigated. The surface morphology and X-ray diffraction (XRD) rocking curves (RCs) for both symmetric and asymmetric Bragg peaks of

From Sponge City to Sponge Earth

Water is most important to sustain all lives on this planet. For thousands of years, human activities have been interacting with Earth’s hydrologic cycle without concept that every water drop counts for societal sustainability. With the rapid increase of population and the challenges of climate change, the humankind must pay more attention to efficient water storage in interaction with the hydrolo

The “gut” corona at the surface of nanoparticles is dependent on exposure to bile salts and phospholipids

Hypothesis: The formation of a biomolecular corona on nanoparticle surfaces significantly influences their biological behaviour, particularly in drug delivery applications. Despite the prevalence of ingestion of particles (e.g, during oral drug delivery), our understanding of corona formation within the gastrointestinal (GI) tract remains limited, especially for non-protein components. The hypothe

Lo-Fi Prototyping a Refreshable Pin Display

This paper presents a way of creating and working with lo-fi materials for a tactile refreshable pin display. The materials were seen to work well, and supported co-design discussions around the future design of, and interaction with, the – as yet, non-existing – tactile device.

Void formation driven by plastic strain partitioning during creep deformation of WC-Co

Creep deformation of WC-Co composites at high temperature and stress is accommodated by either bulk WC creep or by Co-infiltrated grain boundary sliding. It has been proposed that certain grain boundaries are more susceptible than others to such sliding, and depending on the applied stress, the overall deformation rate can be limited by either mechanism. Here, we have used Electron Back-Scatter Di

Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies

When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more lik
