Stable isotopes of nitrogen (delta(15) N) and carbon (delta C-13) were measured for Atlantic salmon Salmo salar and their intestinal cestode, Eubothrium crassum, sharing the same diet. Atlantic salmon muscle tissues were enriched in N-15 and depleted in C-13 compared to their prey (sprat Sprattles sprattus sprattus) and their intestinal cestode. There was no significant difference in delta N-15 or
The objective of this study was to investigate the feasibility of the Aerodynamic Particle Sizer (APS) and the Electrical Low-Pressure Impactor (ELPI) to study mass weighted particle size distributions. Unimodal and bimodal liquid test aerosols were produced to a small chamber. Simultaneous measurements were performed with an APS 3320, an APS 3321, an ELPI and a Dekati Low-Pressure Impactor (DLPI)
There are considerable biomass resources in the European Union (EU) and mature conversion technologies to exploit the potentials of bioenergy. The challenge confronting the EU and member states is how to accelerate the implementation of bioenergy systems. This paper contributes to the identification, analysis, and discussion of barriers for bioenergy in the EU. Adopting an innovative methodology i
The term 'synergy' - from the Greek synergia - means 'working together'. The concept of multiple elements working together towards a common goal has been extensively used in neuroscience to develop theoretical frameworks, experimental approaches, and analytical techniques to understand neural control of movement, and for applications for neuro-rehabilitation. In the past decade, roboticists have s
Popular Abstract in Swedish Syftet är att dels studera olika ventilationssystems förmåga att tillföra och föra bort luftflöden. Den andra delen av syftet är att studera konstruktionskriterier och energi användning för ett variabelflödessystem baserat på konstanttryckshållning av det statiska trycket på grenkanalnivå och som endast tillför uteluft. Ventilationssystemens luftflöden studeras med hjälOne part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only. To inves
The upcoming implementation of the ReFuelEU Aviation Initiative presents both challenges and opportunities for the European aviation sector. Starting January 2025, the EU’s aviation fuel mix must include at least 2% Sustainable Aviation Fuel (SAF), leading to higher operating costs for airlines due to SAF’s higher price than fossil kerosene. Additionally, the entire fuel supply chain will need to
Fresh water resources face risks due to urbanisation, economic development, and climate change (CC). Many small and medium-sized cities (SMCs) are particularly vulnerable to these risks due to the lower resource capacity required to mitigate them. Nature-based Solutions (NbS) for water resource management (WRM) are promising to tackle these issues in urban areas while providing extra benefits to s
In this thesis, a fault detection and diagnosis system is developed for the Crazyflie 2.1 unmanned aerial vehicle. Different types of faults are investigated and suitable methods and tests are implemented. The system is mainly developed for the lighthouse positioning, but the tests and methods are generic and suitable for other parts of the Crazyflie eco-system. For the faults investigated, differ
In this thesis work, the design challenges of building a robust Battery Management System with the existing solutions are discussed highlighting the communication within the battery pack. The initial plan of this master thesis work was to investigate wireless BMS technologies and to implement a wireless BMS, as a demo prototype for three segments with wired BMS for a full 7.2 kWh battery pack. Aft
Purpose – The purpose of this master thesis is to examine the profile of contemporary skills and knowledge provided in Logistics and Supply Chain Management (LSCM) postgraduate programs offered by Swedish universities and compares them with job requirements. Design/methodology/approach – This master thesis employs the desk-based research involving content analysis based on 14 postgraduate LSCM pro
As there currently are not so many known studies which directly evaluate how diversity indices have been used in different contexts, following literature study was made with the purpose of investigating how three of the most commonly used diversity indices (including Shannon-Wiener’s and Simpson’s Indices as well as a certain index measuring taxonomic diversity) are representing different categori
Background: Electroencephalography (EEG) is widely used to assess neurological prognosis in patients who are comatose after cardiac arrest, but its value is limited by varying definitions of pathological patterns and by inter-rater variability. The American Clinical Neurophysiology Society (ACNS) has recently proposed a standardized EEG-terminology for critical care to address these limitations. I
This paper makes a plea for the construction of a common agenda for higher education and science, technology and innovation (STI) policy research. The public higher education and research sector in all countries is currently in the grip of several challenges arising from increased accountability, internationalization and in some cases dwindling resources. Even as the sector is struggling to come t
Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo
The transition towards a sustainable society has become more and more an urban challenge due to a dramatic shift from rural to urban living over the past century. Cities cause environmental and social problems and offer solutions to many sustainability challenges. Living Labs are research infrastructures embedded in a real-life environment, which have recently emerged as a tool for urban governanc
