Novel rotating-cylinder sliding vane rotary compressors (RC-SVRCs) are promising machines in energy conversion systems due to extremely low friction. However, three-dimensional visual investigations on geometrical optimizations of RC-SVRCs are highly limited. Besides, most flow mechanisms and leakage flow affected by geometric structures have not been fully revealed yet. Therefore, the sliding van
Heat exchanger network synthesis is an essential optimisation tool for Process Integration, particularly in energy-intensive industries. Proper design or retrofit of heat exchanger network can enable energy conservation, efficiency improvement, and process debottlenecking. Many earlier pieces of research have focused on the impact of the network structure and process features such as network topol
This paper presents the results from a longitudinal study of the process of developing and implementing a method for risk assessment in a public sector organisation over a period of 3.5 years. The study explores how people involved in this process viewed factors influencing the implementation and what effects the risk management process gave rise to. While a large share of previous research on thi
This paper explores the history of wind power technologies and the integration of wind energy in the Danish energy system. It does so focusing particularly on historical events, socio-cultural and socio-political changes and priorities that were important on this technological journey. From the first primitive wind turbines in the late 1800s, to the world wars, through the energy- crisis in the 70
Acrolein, as one of the most hazardous aldehydes, can be formed among the carbonyls from the combustion of bio-fuels or mixtures of bio- and conventional fuels. Moreover, acrolein is also an important combustion intermediate in the oxidations of higher unsaturated hydrocarbons. A deep understanding of acrolein combustion chemistry will be useful for the kinetic modeling of higher hydrocarbons and
This study aimed to investigate parents’ attitudes towards pedophilia, i.e. their knowledge about pedophilia, stigma of pedophiles and how the society should react to child sexual abuse. Twenty participants were conducted into the survey to answer questions. The study revealed that parents’ attitudes against pedophiles and child molesters were negative and that pedophiles elicited fear in partici
On the 30th-31st of January 2015 a cultural event took place at the concert and congress house of Uppsala in mid-Sweden; Uppsala Konsert & Kongress. The event was called "Irländskt!" (i.e. "Irish!") and consisted of concerts, workshops and sessions. This is a sociological study of the Irish traditional sessions at this event. The participants were studied as part of a commu
Vindkraftens utbyggnad kommer leda till att det i framtiden kommer ställas högre krav på nedstyrning av den aktiva effekten i vindkraftsanläggningar. Denna rapport tar upp hur elproduktionen påverkas vid nedstyrning. Det är inte alltid självklart hur en anläggning påverkas då det är faktorer som turbinlayout, vindriktning och vindhastighet som spelar in. För att kunna modellera nedreglering av deThe expansion of wind power will lead to higher demands on downward regulation of active power in wind power plants. This report treats how the production of electricity is affected by downward regulation. It is not trivial how a wind power plant reacts since factors like turbine layout, wind direction and wind speed have an impact. To be able to model downward regulation of the active power the w
A submerged submarine is highly sensitive to fires since the fire residues cannot be directly ventilated to the atmosphere. Deadly outcome could be the result if the submarine does not reach the surface within time or manages to purify the air while submerged. Reasons for not reaching the surface could be enemies at the surface or system failure. No Swedish submarines are today able to purify fire
The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. The DCO is an electronic component that takes a digital code as input to tune the output operation fr
Purpose: The purpose of this thesis is to analyze the fossilization in language acquisition of Italian of two Swedish learners. I intend to use the Processability Theory and the Theory of gradual construction of italian verbs of the Pavia project. I also intend to investigate the sources of linguistic input of the learners . Methodology: I have recorded two learners as they speak and based on th
Introduction: Phosphomimetic residue and D-loop mutants have been created and their effect studied in the enzyme PARP16. Background: It is known that PARP16 is phosphorylated, and where the phosphorylation sites are, but not how this affects ADP-ribosylation activity. As of yet, there are no reliable ways to obtain 100% phosphorylated PARP16, so it is instead mimicked with amino-acids with simil
This study examines the association between revenue and user base for companies who operate a platform-mediated business model and benefit from network effects. More specifically, the study incorporates both an exponential and linear function in order to see which one most accurately explains the association. Previous research has theorized the notion of an exponential association between revenue
Syftet med studien var att närma oss hur psykodynamiskt inriktade terapeuter som arbetar med barn med traumatiska erfarenheter, upplever sin kliniska verklighet och att få en inblick i på vilket sätt psykodynamisk barnterapi kan göra skillnad för dessa barn. Studien är uppbyggd på en kvalitativ grund och utgår från tolkande fenomenologisk anlays, IPA, (Interpretative Phenomenological Analysis). DaThe aim of the study was to approach how psychodynamically oriented therapists who work with children with traumatic experiences, experience their clinical reality and to gain an insight into how psychodynamic child therapy can make a difference for these children. The study is based on a qualitative basis and is based on interpretive phenomenological analysis, IPA, (Interpretative Phenomenologica
Members have traditionally played a central role in civil society organisations (CSOs) since they typically are the ones who decide upon the course of the organisation and carry out organisational activities. However, with organisations becoming more professionalised, concerns have been raised about the future role of members. Previous research point to different consequences on membership due to
Digitala nomader är personer som genom distansarbete och digitala kommunikationsmedel skapar sig geografisk frihet och flexibilitet. Arbetssättet gör att personen i princip kan arbeta platsoberoende så länge en internetuppkoppling finns. Distansarbete är en ökande trend i samhället. År 2014 införde till exempel Estland ett digitalt e-medborgarskap, och blev först ut i världen med att erbjuda ett sDigital nomads are people who create geographical freedom and flexibility through teleworking and digital means of communication. The working method means that the person can, in principle, work independently as long as there is an internet connection. Teleworking is a growing trend in society, and, for example, Estonia introduced a digital e-citizenship in 2014 and became the first in the world t
