Jet impingement cooling was investigated on a flat heating surface placed in a flow channel, including single jet cooling, in-line double jet cooling, and combined crossflow and jet cooling; cross-flow cooling was a baseline for comparison. In addition, the in-line double jet cooling was explored with various jet distances. Local Nusselt number distribution was experimentally achieved by the liqui
This paper highlights changes in perceived room for agency and local institutions (formal and informal) in old Swedish mill regions. The paper draws on recent literature on change agency (Grillitsch & Sotarauta, 2020) and reproductive agency (Bækkelund, 2021; Jolly et al., 2020) as well as the role of institutions in local communities (Bole, 2021; Rodríguez-Pose, 2013) and builds on material f
Aim: To investigate school nurses’ experiences of health-promoting work to prevent stress in Swedish adolescents. Materials and methods: Swedish school nurses (n = 225) responded to a web survey with open-ended questions. The results were subjected to a qualitative content analysis. Results: Six categories were identified from the analysis: (1) Knowledge of body and soul, (2) Identifying stress an
Objective: To estimate the genetic contribution to doctor-diagnosed hand osteoarthritis (OA). Methods: Using data from the Swedish Twin Registry and National Patient Register, we conducted a 20-year population-based longitudinal cohort study including 59,970 twins aged 35 years or older. We studied inpatient and outpatient doctor-diagnosed hand OA using ICD-10 codes from 1997 until 2016, including
The extraction of the W-boson mass, a fundamental parameter of the Standard Model, from hadron-hadron collision requires precise theory predictions. In this regard, angular coefficients are crucial to model the dynamics of W-boson production. In this work, we provide, for the first time, angular coefficients at NNLO QCD + NLO EW accuracy for finite transverse momentum W-boson at the LHC. The corre
We use principal component analysis to study the hydrodynamic attractor in Yang-Mills kinetic theory undergoing the Bjorken expansion with color glass condensate initial conditions. The late-time hydrodynamic attractor is characterized by a single principal component determining the overall energy scale. How it is reached is governed by the disappearance of single subleading principal component ch
Background: We aimed to describe baseline characteristics of patients with oral anticoagulant-related intracerebral hemorrhage (OAC-ICH) in Sweden and to identify predictive variables associated with receiving hemostatic treatment in the event of OAC-ICH. Methods: We performed an observational study based on data from Riksstroke and the Swedish Causes of Death Register to define baseline character
The ordinary Black diagram of bitumen has only two dimensions. Thus, it does not differentiate the complex shear modulus and phase angle measured under different temperature and frequency conditions. This study proposes to extend the Black diagram to three dimensions by adding a temperature axis. It leads to the combination of multiple necessary ordinary plots in the same three-dimensional (3D) sp
Multiple sclerosis (MS) is a chronic neurological disease believed to be caused by autoimmune pathogenesis. The aetiology is likely explained by a complex interplay between inherited and environmental factors. Genetic investigations into MS have been conducted for over 50 years, yielding >100 associations to date. Globally, the strongest linkage is with the human leukocyte antigen (HLA) HLA-DRB5*0
Introduction: In Sweden, partner's presence during childbirth is generally recommended. However, cultural values and norms in some immigrant societies can be an obstacle to this. Objective: To examine the experiences of Cameroonian fathers during their women's labour and childbirth in Sweden. Design: An exploratory qualitative study with semi-structured interviews were used for data collection and
To improve the power handling capability at ground stations of a 5.8-GHz solar space power satellite using microwave power transmission, a power charge-pump meta-semiconductor field-effect transistor (MESFET)-based rectifier is presented in this article. Unlike conventional microwave Schottky diodes, diode-connected MESFETs, whose nonlinear characteristics help them to have a unique current&#x
Hjärtstopp inträffar när hjärtat plötsligt slutar slå och är ett livshotande tillstånd. Av personer som drabbas av hjärtstopp utanför sjukhus överlever endast en av tio fram till utskrivning från sjukhuset. Hjärnan har en hög ämnesomsättning och små energidepåer. Därför är hjärnan extra känslig för effekterna av ett hjärtstopp. När hjärtat slutar slå och blodet inte kan cirkulera i kroppen riskeraBackground: The brain is susceptible to hypoxic-ischemic brain injury in conjuction with out-of-hospital cardiac arrest (OHCA). Cognitive impairments are documented in about half of all OHCA survivors, however with a pronounced heterogeneity in measurements and findings. More detailed studies and instruments that are sensitive to OHCA-related cognitive impairment, including predictive models to id
Information-theoretic Bayesian optimization techniques have become popular for optimizing expensive-to-evaluate black-box functions due to their non-myopic qualities. Entropy Search and Predictive Entropy Search both consider the entropy over the optimum in the input space, while the recent Max-value Entropy Search considers the entropy over the optimal value in the output space. We propose Joint
Background: Obesity is a chronic disease with increasing prevalence. We aimed to explore primary care physicians’ knowledge and attitudes about obesity and how knowledge and attitudes are associated with confidence and adherence to obesity guidelines and barriers to obesity treatment. Methods: A questionnaire survey was sent by e-mail to 1642 primary care physicians in four regions in Sweden. The
Robot skills systems are meant to reduce robot setup time for new manufacturing tasks. Yet, for dexterous, contact-rich tasks, it is often difficult to find the right skill parameters. One strategy is to learn these parameters by allowing the robot system to learn directly on the task. For a learning problem, a robot operator can typically specify the type and range of values of the parameters. Ne
This study investigates how the spread of boarding passengers between the doors of a train affects the probability of dwell time delays for commuter trains. We make use of automatic passenger count data, collected on a door-by-door level, from commuter trains in the Southern region of Scania in Sweden. The aim of our study is to understand the context in which potential measures to spread out boar
Traffic models can be used to study evacuation scenarios during wildland-urban interface fires and identify the ability of a community to reach a safe place. In those scenarios, wildfire smoke can reduce visibility conditions on the road. This can have serious implications on the evacuation effectiveness since drivers would reduce their speed in relation to the optical density on the road. To date
