Heat transfer characteristics in a latticework duct with various sidewalls are numerically investigated. The crossing angle is 90 deg and the number of subchannels is eleven on both the pressure side and suction side for each latticework duct. The thickness of the ribs is 8 mm and the distance between adjacent ribs is 24 mm. The investigation is conducted for various Reynolds numbers (11,000 to 55
Objective: Antimicrobial resistance is a growing worldwide problem and is considered to be one of the biggest threats to global health by the World Health Organization. Insights into the determinants of antibiotic prescribing may be gained by comparing the antibiotic usage patterns of Australia and Sweden. Design: Publicly available data on dispensed use of antibiotics in Australia and Sweden betw
Importance: Recent studies have questioned the presumed low-risk status of patients with asymptomatic nonsevere aortic stenosis (AS). Whether annual N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements are useful for risk assessment is unknown. Objective: To assess the association of annual NT-proBNP measurements with clinical outcomes in patients with nonsevere AS. Design, Setting, a
BACKGROUND: Previous research has provided evidence for cognitive dysfunction as a common symptom of systemic lupus erythematosus (SLE). In light of this, the primary goal of this study was to investigate how cognitive impairment in this patient group develops over time. In addition, the present dataset contributes to delineating the specific abilities that are impaired in SLE patients as well as
Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. This enables a large number of quantum operations before the system loses its coherence. Anothe
Background: Swedish Emergency Departments (EDs) see 2.6 million visits annually. Sweden has a strong tradition of health care databases, but information on patients’ pathways to the ED is not documented in any registry. The aim of this study was to provide a national overview of pathways, degree of medical acuteness according to triage, chief complaints, and hospital admission rates for adult pati
Although capacity development has been a key aspect of global aid policy for decades, success is limited. Capacity development is defined as a process, based on a partnership, to develop capacity to achieve a goal. The purpose of this thesis is to increase our understanding of why capacity development does not work as intended, and to inform the discussion on addressing the challenges. Two researc
Rotating swings are found in many different versions in parks around the world. They are beautiful examples of the equivalence between gravitational and inertial mass: empty swings and swings with heavy adults hang at the same angle to the vertical. However, sometimes one can notice empty swings moving in a different pattern in an outdoor ride, where wind can induce additional motion, sideways or
In this introductory article, we explain the purpose of this special issue that is set up as a Festschrift in honour of the (editorial) work of BengtJohannisson. Inspired by Italo Calvino's Six Memos for the Next Millennium, the special issue is structured along six essays that are both commemorative and affirmative, that is we use the work of Johannisson to explore fresh waters and invent new pra
BACKGROUND: In patients with Alzheimer's disease (AD), atrophy of the entorhinal cortex (ERC) and hippocampal formation may induce degeneration of connecting white matter tracts.OBJECTIVE: We examined the association of hippocampal subfield and ERC atrophy at 7 tesla MRI with fornix and parahippocampal cingulum (PHC) microstructure in patients with early AD.METHODS: Twenty-five patients with amnes
Background: Alzheimer's disease (AD) causes progressive decline of cognition and function. There is a lack of systematic literature reviews on prognostic and predictive factors in its early clinical stages (eAD), i.e., mild cognitive impairment due to AD and mild AD dementia. Objective: To identify prognostic factors affecting eAD progression and predictive factors for treatment efficacy and safet
Context: Clinically assisted hydration during end-of-life care among patients with cancer is controversial; practice varies between clinical settings and countries, and there is a lack of evidence. Objectives: To examine whether breathlessness, respiratory secretion, or confusion correlates with receiving parenteral hydration during end of life, adjusted for sex, age, and place of death. Methods:
Enligt forskare och praktiker innebär klimatförändringarna särskilda utmaningar för freden. För att förstå vilka dessa utmaningar är och hur man ska hantera dem måste man ta hänsyn till kön, eftersom både erfarenheter av och processer för fred, samt drivkrafter bakom klimatförändringar är könsbundna. Exempelvis kan kvinnor och män uppleva förhållandena efter en vapenvila på olika sätt, eller så kaScholars and practitioners argue that climate change poses particular challenges for peace. In order to understand what these challenges are and how to tackle them necessitates attention to gender, since experiences and processes of peace are gendered, as are experiences and drivers of climate change. For instance, women and men may experience conditions after a ceasefire differently, or climate h
Snapshot spectral imaging enables the acquisition of hyperspectral images (HSI) employing specialized optical systems, such as the coded aperture snapshot spectral imager (CASSI). Specifically, the CASSI system performs spatiospectral codification of light obtaining two-dimensional projected measurements, and these measurements are then processed by computational algorithms to obtain the desired s
Blood-based biomarkers for screening may guide tau positrion emissition tomography (PET) scan referrals to optimize prognostic evaluation in Alzheimer’s disease. Plasma Aβ42/Aβ40, pTau181, pTau217, pTau231, NfL, and GFAP were measured along with tau-PET in memory clinic patients with subjective cognitive decline, mild cognitive impairment or dementia, in the Swedish BioFINDER-2 study (n = 548) and
A 12-bit time-interleaved (TI) analog-to-digital converter (ADC) with pipelined successive-approximation (SAR) channels is presented in this paper. The ADC consists of four TI channels, each incorporating a two-stage pipelined asynchronous SAR ADC. To facilitate clock distribution, a common bootstrapped sampler in front of the four channels is employed. The reset switch in the capacitive digital-t
Introduction: Primary prophylaxis is the gold standard in severe haemophilia A (SHA) but time to escalate the prophylaxis regimen varies. Aim: Assess prophylaxis implementation and long-term joint health outcomes in SHA with primary prophylaxis. Methods: Adult male patients born after 1980, with SHA on primary prophylaxis, started before the age of 3 years and second joint bleed, and no history of
