The aim of this paper is to critically analyse so-called ‘successful’ low-carbon energy transitions under the energy justice magnifying glass. We focus on two case studies that have been arguably referred to as successful local energy transitions in the literature: Samsø (Denmark) and Feldheim (Germany). The study examines community perspectives and causal inferences about perceived energy (in)jus
Remaining competitive as a company in a rapidly changing global environment is becoming challenging from day to day. In recent years, the establishment of so-called shared service centers gained popularity and growing number of companies centralizes supporting service in separate business units to bundle those services and perform them efficiently for the rest of the company. The mystery, however,
Information and Communication Technologies (ICT) have relevant positive and negative impacts on environmental sustainability on various levels: First-order effects such as increasing electronic waste streams; second-order effects such as improved energy-efficiency of production; third-order effects such as a product-to-service shift in consumption or rebound effects in transport. In the simulation
Transport energy conservation research in urban transport systems dates back principally to the Organization of the Petroleum Exporting Countries’ (OPEC) “Arab Oil Embargo” (1973–1974) and the Iranian revolution (1979), when global oil supplies became threatened and costs rose steeply. Two subsequent Gulf Wars (1991 and 2003) highlighted the dangerous geo-political dimensions of Middle-Eastern oil
Carbon dioxide could replace nitrogen gas as stripping gas for the production of H2 by the extreme thermophile, Caldicellulosiruptor saccharolyticus, provided that the pH is kept below 7.0. Above this pH, ≥77 mM sodium bicarbonate will be introduced as an extra salt burden to the culture. High concentrations of sugars and salts contribute each to the inhibition of growth and H2 production, which i
The ac frequency in electrical power systems is conventionally regulated by synchronous machines. The gradual replacement of these machines by asynchronous renewable-based generation, which provides little or no frequency control, increases system uncertainty and the risk of instability. This imposes hard limits on the proportion of renewables that can be integrated into the system. In this paper,
Embedded real-time systems must meet timing constraints while minimizing energy consumption. To this end, many energy optimizations are introduced for specific platforms or specific applications. These solutions are not portable, however, and when the application or the platform change, these solutions must be redesigned. Portable techniques are hard to develop due to the varying tradeoffs experie
The global CO2 emissions in 2010 from fossil energy use grew at the fastest rate since 1969. The year 2010 also witnessed that the global oil production did not match the rapid growth in consumption [1]. These recent data further intensify worldwide concerns about greenhouse gas emissions and energy security for a sustained economic development. For a reduced dependence on oil from fossil reserves
This thesis aims to reveal the role and significance of occupational clothing for the wearers, exposing some of the thoughts, ideas and opinions that pharmacy workers have about their work uniform, the white coat. My own experiences from working in an environment (a pharmacy) where occupational uniforms were used was one of the reasons for selecting this thesis topic. My interest was also consolid
Combating climate change and transitioning to fossil-free energy are two central and interdependent challenges facing humanity today. Governing the nexus of these challenges is complex, and includes multiple intergovernmental and transnational institutions. This book analyses the governance interactions between such institutions, and explores their consequences for legitimacy and effectiveness. Us
ABSTRACTBetween the years of 1965 and 1975 some one million apartments were built on an industrial scale in Sweden. The intent was to provide the quickly growing population with modern housing featuring reasonably sized apartments and good functionality; such as central heating and modern kitchens and bathrooms.Some forty years later many of these large multi-family dwellings are in dire need of s
With increasing usage of the Internet, energy consumption of network equipment has become a crucial challenge from both an economic and an environmental point of view. This paper combines users’ behavior of accessing the network with energy saving algorithms for energy-aware network equipment, and investigates potential energy savings in the access network. The study is based on a set of traffic d
Objective. To study the effect of valgus malalignment on knee osteoarthritis (OA) incidence and progression. Methods. We measured the mechanical axis from long limb radiographs from the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI) to define limbs with valgus malalignment (mechanical axis of >= 1.1 degrees valgus) and examined the effect of valgus alignment versus
The initial purpose of this study is to investigate and clarify the function and debate in Swedish policy on cybersecurity and cyber defense. How does it work and what threats does the development of digitalisation pose when it comes to both societal functions and everyday services? Cyber security and cyber defense is a relatively new area of research compared with many other study objects wit
Decarbonising the built environment is essential to mitigating the climate crisis, as buildings significantly contribute to greenhouse gas emissions. Adaptive reuse presents a sustainable alternative to demolition and new construction. This study evaluated the Global Warming Potential (GWP) of an adapted building through renovation and operation across three scenarios, compared to a reference scen
