Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

Impleamini agnicione voluntatis Dei : En predikan ur Skoklosterhandskriften

This essay describes my work as a director in a specialized orientation within psychodrama, surrealistic psychodrama. Using the language and performance techniques of theater and under the guidance of a director, psychodrama creates an improvised narrative or story. The essay describes several dramas I have directed, reflecting on my actions and choices as a director and group leader. I examine whether my working method has allowed me to be spontaneous and creative, which I believe the example of "The dangerous bear" demonstrates. The process enabled me to establish trust and receptivity so that a newly constituted group dared to investigate conflicts in symbolic ways associated with illness and death.

Vad ska man mäta för att veta? ? en studie av resursfördelningen inom Stockholms stadsbibliotek

The purpose of this master?s thesis is to study resource allocation among district libraries within Stockholm?s City Library (SSB) on three different occasions ? 1996, 2001 and 2005 ? and to examine whether there exist any inconsistency between the state of the allocation of resources and what might be considered reasonable. During the course of the study, it became apparent that some measurements are more relevant than others when determining whether the allocation of resources is reasonably fair. The most relevant ratio is the share of net cost per capita in relation to population and the population?s composition of children, youngsters and persons with foreign background as a result of relevant political governing documents giving priority to these three groups.

Hur påverkar förtätningen stadens grönstruktur? :

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

Kulturkrock i skolan : Skapande skola ur kulturaktörernas perspektiv

Kulturorganisationer är en typ av organisationer som skiljer sig från andra. Istället för att drivas av ett vinstintresse styrs de av konstnärliga värderingar. En viktig förutsättning för att deras verksamhet ska fungera är statliga subventioneringar, vilket medför att de blir starkt knutna till statens nycker. År 2008 infördes satsningen Skapande skola, vilken innebär att skolhuvudmän kan söka bidrag för att genomföra kulturprojekt för grundskoleelever i sam-arbete med professionella kulturaktörer. Denna satsning är en betydande potentiell resurs i kulturaktörernas omgivning och vi intresserar oss för hur de påverkas av att nya resurser till-gängliggörs.Studien består av kvalitativa intervjuer med personer från sex olika kulturorganisationer från skilda delar av Sverige.

A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

Kompetensf?rs?rjning under digital transformation En kvalitativ studie om hur sm? och medelstora managementkonsultbolag i Sverige arbetar med kompetensf?rs?rjning

The aim of this thesis is to analyze how small and medium-sized management consulting firms in Sweden work with human resource management during digital transformation. By interviewing companies, this study explores their approach to attracting, recruiting, and developing competence. The results showed that management consulting firms have good access to candidates, made possible by having a strong corporate culture and attractive working conditions - Crucial parts for attracting talent. Social media and networking are frequently used for marketing and attracting interesting candidates. Digital tools and social media showed to be useful during the recruitment process, but personal contacts and networking still play a central role.

Återanvändning som kommunikativ resurs : En samtalsanalytisk studie av kommunikation med PECS hos en pojke med diagnosen autism

Communicative recycling, to repeat utterances uttered by oneself or others, is a common phenomenon in all societies and languages. The talk of persons with autism often features recycling. The aim of this study was to identify different forms of recycling in communication involving a boy with autism and to describe its functions. Communication between the boy with autism, who used Picture Exchange Communication System (PECS) to communicate, and his parents and teachers was videotaped. The conversations took place in familiar settings, in the boy?s home and at his pre-school.

Liten vill bli stor - Effekter av Turkiets tullunionsbildande med EU

Turkey?s nearly fifty-year-old aspiration for admittance to the European Union took a crucial step forward with the signing of the Ankara agreement in 1996. The aim of this thesis is to examine the trade effects that evolve from the creation of a customs union. Our objective is to study how Turkey?s trade patterns adapted to the liberalized trade by examining the effects on resource allocation, specialization and welfare.

Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

Nutritionens betydelse för akut traumatiskt hjärnskadade patienter

The aim of the literature review was to illuminate the importance of nutritional management to patients who have sustained a traumatic brain injury (TBI) and describe nurses responsibility and meaningful function in the nutritional support. TBI patients tend to be associated with hypermetabolism and hypercatabolism, resulting in negative nitrogen balances. The results reveal increased energy expenditure and assessments of needs energy requirements at the TBI patients. This study determining the route of feeding: enteral versus parenteral nutrition. Furthermore describes complications associated with enteral feeding.

"Jag tycker det är en snäll typ av marknadsföring" : - En kritisk diskursanalys om content marketing i podcasts.

The aim of this study was to investigate in what way content marketing can be understood through podcasts as an alternative marketing tool. The material which the study was based on is Ölpodden, a podcast initiated by Carlsberg Sweden. The study intended to shed light on the interdiscursivity that emerges when brands are communicated through podcasts. Another aim was to understand how relationships and identities are constructed through the podcast by examining its intended audience. In order to achieve this a critical discourse analysis was used as both underlining theory and comprehensive method.

Läsande lyssnare ? lyssnande läsare. En kvalitativ studie av ljudboksanvändare

The purpose of this thesis is to investigate peoples experience when listening at audio books. During recent years the use of audio books has increased significantly. With that knowledge and the fact that this is an almost unexplored area within Library- and Information science our interest grew even stronger. The thesis is based on two different theories. To be able to place audio books in a context we have applied a media- consumption perspective by asking questions like when, where and how the media-consumption takes place.
