The combustion engine, a well-known source of aerosols, has seen remarkable improvements regarding efficiency and emissions. A drawback of the conventional compression ignition (CI) engine is its requirement for a high cetane number fuel, i.e. diesel which contains long carbon chains forming particulate matter (PM) when combusted in the conventional diesel combustion (CDC) process. A previous stud
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into lignocellulosic biorefineries they can become a keystone in a future bioeconomy. In order to achieve this, pulp mills have to close their loops and focus on the optimal utilisa
Localization is an important enabling technology for many applications, such as wireless sensor networks, emergency rescue services, civil defense and transportation. Suppose that a room is equipped with several microphones (or sensors), and one person is making a sound while moving around in the room. Can one find microphone and sound source positions as well as reconstruct a room geometry? The a
A 3D model at microscale by the lattice Boltzmann method (LBM) is proposed for part of an anode of a solid oxide fuel cell (SOFC) to analyze the interaction between the transport and reaction processes and structural parameters. The equations of charge, momentum, heat and mass transport are simulated in the model. The modeling geometry is created with randomly placed spheres to resemble the part o
The Multi-plume Aerosol dynamics and Transport (MAT) model has been developed to study the dynamics of the particle size distribution in urban environments. The MAT model uses a novel multi-plume scheme for vertical dispersion and routines of the aerodynamics models AERO3. It treats the processes: emission from a near ground source, dilution with background air, deposition, coagulation and condens
ABSTRACT Soft tissue tumor-associated gene fusions are currently being used as diagnostic genetic markers and seem promising as potential prognostic markers. In the present study, a new fusion gene was discovered in one case of a specific subtype of soft tissue sarcoma displaying a t(6;16) translocation. Using fluorescence in situ hybridization (FISH), the FUS gene in 16p11 was shown to be rearra
In recent years, lithium production has been increasing as a result of the growing market demand. Salt-lake brines are one of the main sources of raw lithium, which can be concentrated and purified by natural evaporation. This time-consuming production causes a loss of around 85–95 % of the water contained in the extracted brine. In this context, new technologies could replace the current process
Titel: Musikens Budskap - Mytologi och folktro som tema i instrumental konstmusik Författare: Erik Valdemar Sköld Handledare: Francisca Skoogh I denna skriftliga uppsats redogör jag för bakgrunden och arbetsprocessen till tre av mina egna kompositioner vars inspirationskälla och tema är kopplat till naturen och nordisk mytologi. Frågeställningen lyder följande: vilka tillvägagångssätt inom programIn this essay, I describe the background to and work process behind three of my own compositions which are inspired by nature and Nordic mythology. I asked myself: which approaches, from programmatic music throughout history, can I use in my own work as a composer? I go through some historical examples that use references to nature, and summarise literature about program music and affects, in orde
The first three US Presidents of the century have, to say the least, had differing views concerning the nature of climate change and how this issue is addressed most appropriately – as noted by the fact that the issue has gone back and forth between being a security issue and basically disappearing from the security agenda altogether. In order to shine a light on how this has happened, this study
Bakgrund: Personer med psykisk ohälsa har ofta en nedsatt förmåga att bearbeta sinnesintryck. Tidigare har kopplingen mellan det individuella sättet att hantera sinnesintryck och olika sociodemografiska faktorer undersökts hos psykiskt friska personer, men studier gällande detta saknas för personer med psykisk ohälsa. Syfte: Att undersöka sensoriska bearbetningsmönster och deras eventuella kopplBackground: People with mental illness often have a reduced ability to process sensory inputs. Previously, the link between the individual way of dealing with sensory inputs and sociodemographic factors has been investigated in mentally healthy people, but there’s a lack of similar studies for people with mental illness. Aim: To investigate sensory processing patterns and their possible connecti
Oil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid
Abstract: Employer branding process that creates the best match possible between the employer and the employee, leads to a business satisfaction and a person-organization fit. Not surprisingly, an efficient employer branding strategy also decreases the labour turnover rate within the company and helps to retain the talent. Naturally, the specified situation is desired by the employer and by the po
I believe that vision, image and identity, brand and positioning are all parts of repositioning process. When repositioning, company has to decide if it is going to compete with same attributes as before or if company is entering totally new competitive domain with new dimensions. Fleur de Santé has changed its identity and chose which parts of it to point out; history, brand and natural ingredien
Currently well established technology-based manufacturing companies with a service business provides their markets with innovative and reliable products. Despite this, these companies often find their service delivery process to be inefficient, due to its time-based nature. Furthermore, the markets on which they operate are currently experiencing a shortage of qualified service personnel and thus
Two different techniques exist for glass fiber production, direct melt bushing and marble bushing. The purpose of the project was to study the glass fiber production process and investigate the possibilty of constructing mathematical models from experimental data. This part also included implementation of a DAQ system to obtain the expeimental data. A second objective was to construct an efficent
