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
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
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
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
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
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
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
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 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.
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
X-ray imaging can be improved by utilising the wave-optical properties to extract images of complementary contrast. Normal x-ray imaging relies only on attenuation in the sample, but information about phase shift and scattering of the x-rays can be computed when special conditions are fulfilled.

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.
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
Collagen VI assembly is unique within the collagen superfamily in that the alpha 1(VI), alpha 2(VI), and alpha 3(VI) chains associate intracellularly to form triple helical monomers, and then dimers and tetramers, which are secreted from the cell. Secreted tetramers associate end-to-end to form the distinctive extracellular microfibrils that are found in virtually all connective tissues. Although
The type III receptor tyrosine kinase FLT3 is frequently mutated in acute myeloid leukemia. Oncogenic FLT3 mutants display constitutive activity leading to aberrant cell proliferation and survival. Phosphorylation on several critical tyrosine residues is known to be essential for FLT3 signaling. Among these tyrosine residues, Y842 is located in the so-called activation loop. The position of this t
This article addresses the future of Brazil's bioethanol sector, focusing on its capabilities to innovate, its efforts toward producing cellulosic ethanol, and on recently implemented policies. Contrary to what has been argued in the literature, Brazil may not be prepared to face the technological and market challenges now emerging in the biofuels domain worldwide. Important productive investments
