In clinical practice as well as research situations, it is of great importance to get reliable information about a patient's alcohol consumption. The aim of the study was to investigate the correlation of alcohol biomarkers (phosphatidylethanol [PEth], carbohydrate-deficient transferrin [CDT], γ-glutamyltransferase, aspartate aminotransferase, and alanine aminotransferase) to retrospective as well
Future district heating systems (so called 4th Generation District Heating (4GDH) systems) have to address challenges such as integration of (de)centralized renewable energy sources and storage, low system temperatures and high fluctuation of the supply temperature. This paper presents a novel framework for representing and simplifying on-grid energy systems as well as for dynamic thermo-hydraulic
Livscykelanalys (LCA) används för att utvärdera den potentiella miljöpåverkan av olika processer och tjänster, bland annat inom bygg- och fastighetssektorerna. Denna studie jämför tre LCA-verktyg som är speciellt utvecklade för användning inom bygg- och fastighetssektorn mot ett fjärde som är ett allmänt LCA-verktyg. En LCA görs för en fallstudie av ett flerfamiljshus där ett ventilationssystem meLife cycle assessment (LCA) is used to evaluate the potential environmental impact of different processes and services, including in the construction and real estate sectors. This study compares three LCA tools that have been specifically developed for use in the construction and real estate sectors with a fourth that is a general LCA tool. An LCA is performed for a case study of a multi-family bu
Energy communities are emphasized by the EU as important for developing sustainable energy systems that include and engage many people. While many renewables are highly compatible with a more decentralized energy system, research indicates that participation in 'desirable' energy activities and energy decision-making is influenced by social and economic factors, including gender, economic status a
The cooperative emission of interacting nanocrystals is an exciting topic fueled by recent reports of superfluorescence and superradiance in assemblies of perovskite nanocubes. Several studies estimated that coherent coupling is localized to a small fraction of nanocrystals (10−7-10−3) within the assembly, raising questions about the origins of localization and ways to overcome it. In this work, w
Practice theories have generated interest in sustainability transitions research as a means to study shared expectations, conventions and routines that maintain unsustainable consumption within the dominant regime. However, collective action to change practices, which is crucial for innovation, is seldom examined in practice theory research. This article applies practice theories to conceptualize
This history of wind energy in Denmark describes how top-down policy support and bottom-up initiatives shaped the Danish wind power sector, ultimately facilitating the integration of wind energy in the grid. From the early days of wind power, innovative entrepreneurs tinkered with and improved upon the emergent wind power technologies, but coal and oil remained the prioritized fuels for the almost
Background: Type 2 diabetes often displays hyperlipidemia. We examined palmitate effects on pancreatic islet function in relation to FFA receptor GPR40, NO generation, insulin release, and the PPARgama agonistic thiazolidinedione, rosiglitazone. Principal findings: Rosiglitazone suppressed acute palmitate-stimulated GPR40-transduced PI hydrolysis in HEK293 cells and insulin release from MIN6c cell
This study is an exploration of the interdisciplinary field of urban sustainable development in the first stage of a PhD project in human ecology. The purpose of the PhD project is to study the premises for urban sustainable development in the context of (relatively) affluent economies in Europe or, more generally, in the North. My case study is Malmö placed in the Öresund region farthest south of

Popular Abstract in Swedish Förbränning av fossila bränslen som bensin, kol, olja och naturgas orsakar att koldioxid ackumuleras i atmosfären, vilket är en av orsakerna till global uppvärmning. Transportsektorn står för största delen av Sveriges användning av bensin och olja. Oljan är importerad från andra länder, som gör oss väldigt beroende av omvärlden. Ett av de mest lovande alternativa bränslTransportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of secon
This article argues that while HTS’s transformation and split from al-Qaeda is real, al-Jolani must be pressured to share power over Idlib and loosen his group’s authoritarian grip, which is causing grievances that in the long term will push locals into the hands of radical groups like ISIS and al-Qaeda.
According to conventional wisdom, improving energy efficiency is an easy way to mitigate climate change and improve energy security, though the reduction in energy intensity in developed economies is largely due to offshoring energy-intensive production to developing countries. This chapter presents a contrarian view. Theory, historical evidence, and time series analysis suggest that the economy-w
The growing utilization of second homes has led to extended heating periods and, to some extent, renovations to enhance their standards, resulting in increased energy and resource consumption. This study, conducted in Sweden, investigates user patterns across various seasons, heating systems, and implemented energy renovation measures. Findings reveal that 40% of second homes in winter sport areas
Single-master multi-slave (SMMS) teleoperation systems can perform multiple tasks remotely in a shorter time, cover large-scale areas, and adapt more easily to single-point failures, thereby effectively encompassing a broader range ofapplications. As the number of slave manipulators sharing a communicationnetwork increases, the limitation of communication bandwidth becomes critical. To alleviate b
Using an extended Kaya decomposition, we identify the drivers of long-run CO₂ emissions since 1800 for Denmark, France, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, the UK, the United States, Canada and Japan. By considering biomass and carbon-free energy sources along with fossil fuels, we are able to shed light on the effects of past and present energy transitions on CO₂ emissions.
