Reciprocating compressors hold great promise for enhanced efficiency across a wide variety of microscale and macroscale systems. This article investigates the potential of isothermal compression strategies by introducing two modeling approaches for the time-dependent analysis of reciprocating compressors. First, a thermodynamic model is developed based on conservation of mass and energy for a cran
Fire safety provisions in building regulation are about managing risk. In order to appropriately characterize and incorporate risk measures into building regulation, it is helpful to view building regulatory systems (BRS) as complex socio-technical systems (STS), wherein there are interactions between institutions, technology and people, which ideally work together to mitigate risk to a societally
In 1953 Eva Hansen-Melander was appointed as a scientific assistant at the newly founded Cancer chromosome laboratory at Lund University, Sweden. The lab was set up by the cytologist Albert Levan, who started his career as a botanist studying Allium chromosomes but in the early 1950s changed his research focus to the studies of chromosomes in cancer cells. Levan developed close collaborations with
Purpose: The knowledge about young adults who have lost a parent to cancer is limited, and to reach a broader understanding about this group, this study used the Dual Process Model of Coping with Bereavement (Stroebe and Schut, 1999) as a theoretical framework. The purpose of this study was to describe loss- and restoration-oriented bereavement stressors and psychosocial wellbeing of young adults
Introduction: The transgender population is a marginalized group in society and research suggests that they experience significant barriers when accessing health care. However, little is known about transgender and gender-diverse people and their experiences of encounters with healthcare professionals in Sweden. Aim: To explore transgender and gender-diverse people's experiences of accessing healt
The clinical consequences of arterial atherosclerotic lesions depend, apart from their size, on their composition of cellular and extracellular components. While an intact endothelium at the interface of atherosclerotic plaques towards the blood can prevent its erosion, underlying smooth muscle cells within the plaque can reduce the risk of plaque ruptures, due to the deposition of stabilizing ext
Film cooling, as an effective protection technology, is widely applied in gas turbines to prevent components like vane blades from the hot mainstream. However, ash and other contaminants contained in the gas easily deposit on blade surfaces, which results in blockages inside the film holes and a reduction of the coverage area of the coolant air. Two blockage configurations (hemispherical and tetra
In the sporadic permafrost zone of North America, thaw‐induced boreal forest loss is leading to permafrost‐free wetland expansion. These land cover changes alter landscape‐scale surface properties with potentially large, however, still unknown impacts on regional climates. In this study, we combine nested eddy covariance flux tower measurements with satellite remote sensing to characterize the imp
This paper proposes a simple and improved approach of estimating MIMO capacity from antenna magnitude patterns, i.e., the antenna patterns are phaseless. The simple approach synthesizes the phases according to the antenna spacing, and it compares favorably with an existing approach based on random phase synthesis. Moreover, the simple approach can be improved by taking into account the correlation
Background: Controversy exists as to the health effects of exposure to asphalt and crumb rubber modified (CRM) asphalt, which contains recycled rubber tyres. Objective: To assess exposures and effects on airway symptoms, lung function and inflammation biomarkers in conventional and CRM asphalt road pavers. Methods: 116 conventional asphalt workers, 51 CRM asphalt workers and 100 controls were inve
The objective in this research has been to predict the current and future moisture and temperature distribution in a concrete reactor containment, RC. The overall objective in this project was to create a model to be able to predict the moisture and temperature distribution in the concrete wall of the RC of a Pressurized Water Reactor, PWR. In addition, one objective was to design a model to simul
Towards a Cultural Politics of Climate Change provides a new perspective on how climate change matters in policy-making, business and everyday life. It argues that the work of low carbon transitions takes place through the creation of devices, the mobilisation of desires, and the articulation of dissent. Using case studies from the US, Australia, and Europe, the book examines the creation and cont
Dental caries is the most common oral disease that causes demineralization of the enamel and later of the dentin. Depth-wise assessment of the demineralization process could be used to help in treatment planning. In this study, we aimed to provide baseline information for the development of a Raman probe by characterizing the mineral composition of the dental tissues from large composition maps (6
Multiple myeloma (MM) is a hematological disease of the plasma cell that remains clinically challenging despite the development of novel therapies. Epigenetic alterations have been demonstrated to contribute to MM pathogenesis, yet comprehensive studies into the links between different epigenetic regulatory systems in myeloma progression and drug resistance, though clinically relevant, are largely
Background and Aims The prognosis of adult-onset type 1 diabetes (T1D) and prognostic factors are sparsely investigated. This study assessed mortality, major adverse cardiovascular events (MACE), and prognostic factors in adult-onset T1D, particularly focusing on those diagnosed at age ≥40. Methods Participants were people diagnosed with adult-onset T1D (n = 10 184) or type 2 diabetes (T2D, n = 37
In this study, we use direct numerical simulations to investigate turbulent premixed ammonia flames assisted by non-equilibrium nanosecond plasma discharges and hydrogen addition. The results reveal the coupling effects of turbulence, the hydrogen concentration in the fuel blend, and plasma discharges on the microscopic structure of the flame and chemical pathways. It is found that the flame front
Ferroelectric thin films present a powerful platform for next-generation computing and memory applications. However, domain morphology and dynamics in buried ferroelectric stacks have remained underexplored, despite their importance for real device performance. Here, nanoprobe X-ray diffraction (nano-XRD) is used to image ferroelectric domains inside BiFeO3-based capacitors, revealing local disord
The Swedish government decided in 1994, as part of the so-called 50,000 Swedish crowns scheme, to set aside a portion of the labour market budget for the further training and retraining of local government and country council employees. The present article reports on the experiences of the training effort that took place in 1994–1995 and provides a theoretical framework for discussing staff traini
