This paper evaluates the multi-service operation of a heterogeneous second-life battery energy storage system (ESS) participating in the day-ahead electricity market and frequency containment reserves (FCR-N, FCR-D Up, FCR-D Down). A rolling horizon mixed integer linear programming (MILP) is developed to co-optimize market revenues, power schedule, and degradation, using linearized calendar and cy
Fossil fuel subsidies strain public budgets, and contribute to climate change and local air pollution. Despite widespread agreement among experts about the benefits of reforming fossil fuel subsidies, repeated international commitments to eliminate them, and valiant efforts by some countries to reform them, they continue to persist. This book helps explain this conundrum, by exploring the politics
Like all businesses there is also an interest in the fire service to always improve the efficiency of its work. This can be done in many different ways, for example by changing the existing formation of the local rescue organization or through the continued development of current methods and equipment that firefighters use. Most rescue services across Sweden are currently using low pressure pumps
Abstract in UndeterminedAccessibility to adequate health services is a basic human right. Israeli road blocks and checkpoints inhibit access to health care for the Palestinian population. While other studies have dealt with the impact of the barriers, few are based on actual measurements of transport times between locations. Geographical information systems (GIS) and network analysis were used to
The use of business excellence models (BEM) has become popular in the last two decades, and several companies have learned how to use them and gained from such models. More companies, we assume, have experienced problems when using such models because of various weaknesses such as too-sophisticated assessment criteria, excessive paperwork, cumbersome procedures and a lack of focus, which have limi
Terrestrial gross primary production (GPP) is the largest global CO2 flux driving several ecosystem functions. We provide an observation-based estimate of this flux at 123 +/- 8 petagrams of carbon per year (Pg C year(-1)) using eddy covariance flux data and various diagnostic models. Tropical forests and savannahs account for 60%. GPP over 40% of the vegetated land is associated with precipitatio
This thesis seeks to examine the relationship between authenticity and co-creation in regards to tourism experiences. In order to explore the relationship between the two phenomena, the visitor/host interaction facilitated through CouchSurfing, an international online hospitality network, is used. This thesis focuses on the analyses of tourist experiences, drawing from narratives provided by inter

Background The clinical distinction between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) is sometimes difficult, particularly in mild cases. Although CSF markers such as amyloid beta 42 (A beta 42) and P-tau can distinguish between AD and normal controls, their ability to distinguish between AD and DLB is not adequate. Objective This study aims to investigate whether CSF markers, i
Aim:The aim was to analyse any associations between socio-demographic and psychosocial factors and different features of the metabolic syndrome in a geographically well-defined population of middle-aged women. Methods:A population of 10 766 Caucasian women aged 50-59 years was investigated regarding biological and socio-demographic conditions, physical activity, dietary habits, aspects of quality
Abstract in UndeterminedThis report is a study of literature found in the field of energy use in single-family houses. It is to be regarded as a first phase, part of the project "Sustainable energy use in houses". The literature examined refers to, predominantly, Swedish conditions, including Swedish building technique and the Nordic climate. The objectives of the report are to present topics of i
The location of the red edge of the ZZ Ceti instability strip is definedobservationally as being the lowest temperature for which a white dwarfwith a H-rich atmosphere (DA) is known to exhibit periodic brightnessvariations. Whether this cut-off in flux variations is actually due to acessation of pulsation or merely due to the attenuation of anyvariations by the convection zone, rendering them invi
In a north European context, identifying invasive species is far from trivial because the vegetation has been influenced by human activities for thousands of years. New species have immigrated continuously since the end of the last glaciation, both spontaneously and through direct or indirect help by man. Still, newly immigrated species may be problematic in a nature conservation context and may h
Human activity in the form of unnecessary consumption is one of the reasons to why we have come to experience climate change. A circular economy is an alternative to the linear economy that promotes consumption, and is based on a theory where waste is turned into resources again in a closed loop. In an ideal circular economy there is no waste and consumption is less dependent on extraction of virg
There have been many calls for higher education to facilitate a transition towards sustainability, in particular, with a social change dimension. Literature exists on the different learning outcomes and competencies expected of students in this process, but not much is written about learning approaches used within curriculums that can enable social change. This thesis aims to address this issue by

Rainforests are of great importance for biodiversity and several ecosystem services. In Rwanda, a considerable decline in rainforest covers have been observed during the last decades. The Gishwati-Mukura Forest is one of the rainforests in Rwanda that has experienced a substantial reduction in forest cover, 99.4 %. The aim of this research has been to investigate what the changes in forest cover o
Objective: The authors sought to clarify the sources of parent-offspring resemblance for drug abuse, alcohol use disorders, and criminal behavior, using a novel genetic-epidemiological design. Method: Using national registries, the authors identified rates of drug abuse, alcohol use disorders, and criminal behavior in 41,360 Swedish individuals born between 1960 and 1990 and raised in triparental
Ecosystem services (ES) is an up-and-coming concept which refers to benefits humanity gets from functions provided by natural systems. Investigating how cities have embraced the ES concept within their urban planning is important in order to be able to assess the awareness of human dependence of nature’s functions and the potential of the ES concept to increase this awareness. In this study, plann
