POOL BOILING HEAT TRANSFER CHARACTERISTICS OF POROUS NICKEL MICROSTRUCTURE SURFACES

Pool boiling is an effective heat dissipation approach in electronic cooling, battery thermal management, etc. This study used the electrochemical deposition method to fabricate one smooth nickel specimen (named Ni-smooth) and three specimens with a porous nickel-stacked structure. The three porous specimens were created with deposition current densities of 0.5 A·cm–2 (named Ni-0.5), 2.0 A·cm–2 (n

Millimeter-wave Scattering from Building Facade : A Simulation and Verification Study

This paper presents millimeter-wave scattering from a building facade predominantly composed of windows. These windows are integrated into the walls, forming dihedral structures that reflect waves toward the incident angle. The scattered field resulting from the building facade is simulated using the two-bounce Geometrical-Physics (GO) method. We analyze the channel in power loss and arrival angle

Air temperature and precipitation constraining the modelled wetland methane emissions in a boreal region in northern Europe

Wetland methane responses to temperature and precipitation are studied in a boreal wetland-rich region in northern Europe using ecosystem process models. Six ecosystem models (JSBACH-HIMMELI, LPX-Bern, LPJ-GUESS, JULES, CLM4.5, and CLM5) are compared to multi-model means of ecosystem models and atmospheric inversions from the Global Carbon Project and upscaled eddy covariance flux results for thei

On gradient based descent algorithms for joint diagonalization of matrices

Joint diagonalization of collections of matrices, i.e. the problem of finding a joint set of approximate eigenvectors, is an important problem that appears in many applicative contexts. It is commonly formulated as finding the minimizer, over the set of all possible bases, for a certain non-convex functional that measures the size of off-diagonal elements. Many approaches have been studied in the

Autoimmune diseases and the risk and prognosis of latent autoimmune diabetes in adults

Aims/hypothesis: The aim of this study was to clarify the impact of autoimmune disease (AD) comorbidity on the risk and prognosis of latent autoimmune diabetes in adults (LADA). Methods: We used data from a Swedish study comprising newly diagnosed cases of LADA (n=586, stratified into LADAlow and LADAhigh by autoantibody levels), type 2 diabetes (n=2003) and matched control participants (n=2355).

The Mantis Network : IV. A titanium cold trap on the ultra-hot Jupiter WASP-121 b

Context. Using emission lines from metals, we investigate the three-dimensional distribution of temperature and chemistry in ultra-hot Jupiters. Aims. Existing observations of WASP-121 b have suggested an underabundance of titanium and titanium oxide in its terminator region. In this study, we aim to determine whether this depletion is global by investigating the dayside emission spectrum. Methods

Best Practice of Peritoneal Dialysis-Associated Gram-Negative Peritonitis in Children : Insights From the International Pediatric Peritoneal Dialysis Network Registry

Introduction: Gram-negative peritonitis (GNP) is associated with significant morbidity in children receiving long-term peritoneal dialysis (PD) and current treatment recommendations are based on limited data. Methods: Analysis of 379 GNP episodes in 308 children (median age 6.9 years, interquartile range [IQR]: 3.0–13.6) from 45 centers in 28 countries reported to the International Pediatric Perit

Successful prevention of organic solvent induced disorders : history and lessons

In this discussion paper, we describe the history of the science and societal action resulting in the mitigation of neurotoxic disorders from exposure to organic solvents at the workplaces in Sweden. When alkyd paints were introduced in large scale in construction painting in the 1960s and 1970s, Scandinavian unions voiced increasing concern as members reported symptoms like headache and vertigo,

Cystektomi för blåscancer – har utfallet förbättrats?

Radical cystectomy (RC) for bladder cancer is a complex procedure with an inherent risk of complications and even postoperative mortality. Historically, RC was performed in 44 hospitals in Sweden, which gradually decreased over time, and since a formal regional centralisation of these operations in 2017, cystectomy care is currently provided by nine hospitals. In the Swedish national urinary bladd

Characteristic Modes and Nonreciprocity

Properties of characteristic modes of lossless scatterers breaking time-reversal symmetry are presented utilizing the scattering formulation of characteristic decomposition. Antennas connected to nonreciprocal circuits and moving material bodies are used as numerical examples.

Population-based Organised Prostate Cancer Testing : Results from the First Invitation of 50-year-old Men

Background: The European Union recently recommended evaluation of the feasibility of organised prostate cancer screening. In Sweden, regional population-based organised prostate cancer testing (OPT) programmes were introduced in 2020. Objective: To describe initial participation rates and diagnostic outcomes. Design, setting, and participants: The three most populated Swedish regions invited all m

‘Say Bible!’: Teaching Biblical Reception

Classes focused on biblical reception might seem to some like a “get out of jail” card in the face of ever-threatening questions about the relevance of biblical studies today. To others, such classes look like a cul-de-sac that fails to lead to either renewed interest in the Bible or meaningful pedagogical outcomes. In this short reflection, I tease out chances and challenges that come with teachi

Talking body : the effect of body and voice anthropomorphism on perception of social agents

Introduction: In human-agent interaction, trust is often measured using human-trust constructs such as competence, benevolence, and integrity, however, it is unclear whether technology-trust constructs such as functionality, helpfulness, and reliability are more suitable. There is also evidence that perception of “humanness” measured through anthropomorphism varies based on the characteristics of

The Bible in the North: Commodity and Content on the Secular Market

Understanding biblical texts in context usually entails an awareness of the times and places in which these texts first emerged and were first encountered. In this article, I aim to make a case for more contextual work on the Bible in the Northern parts of the contemporary world. After discussing contexts in relation to the Bible, I turn to the Global North and questions of secularization, before

Structural change in city systems evolution

This paper analyzes city system dynamics, based on a theoretical framework relating interaction potentials to agglomeration economies and density externalities. It employs new historical time series data on population size of cities in Sweden over two centuries (1810–2010) and introduces two schematic growth factors: (i) the intra-city potential and (ii) the extra-city potential located in in ring

PhD students’ acceptance of the university teaching community’s cultural norms and by the teaching community : a phenomenographic study

One of the aims of PhD students’ socialisation is for them to accept the norms of the teaching culture and to be fully engaged with and accepted by the university teaching community. However, when PhD students enter universities, they do not necessarily accept all of the university teaching community’s cultural norms, nor do they all experience acceptance by the community. This phenomenographic st

Xylene versus Isopropanol for Paraffin Wax Processing of Lung Tissue

The microscopic observation of lung tissue is challenging due to its fragile nature. Xylene and isopropanol are common tissue-clearing reagents used before paraffin embedding, yet no studies have compared these two reagents in lung tissue processing. Due to the well-known health risks xylene could introduce to operators, as well as its environmental hazards, it has long been desired that a less ha

Mechanism of syncope : role of ambulatory blood pressure monitoring and cardiovascular autonomic function assessment

BACKGROUND AND AIMS: Identifying the haemodynamic mechanism of autonomic syncope is the essential pre-requisite for effective and personalized therapy aimed at preventing recurrences. The present study assessed the diagnostic efficacy of a two-step assessment.METHODS: Multicentre prospective, cross-sectional, observational study. Patients affected by severe autonomic syncope underwent a two-step a
