Cleaning process of abattoir wastewater with focus on bacterial pathogens

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

Att gestalta utan plats : en redogörelse för en teambaserad gestaltningsprocess

Within these courses, students are mainly introduced to one type of design process, a process based on the specific site and its conditions, known as Genius Loci. This report presents a course and a design methodology from Cornell University which aims to provide students with tools for a more conceptual way of thinking about design and architecture. The design method is presented in two stages. First an introduction to the course description and objectives.

En persona i frihetstidens politiska rum : Bonden i ridderskapet och adelns tankevärld i 1740-talets Sverige

This essay is a contribution to the process of reconstructing the meaning of a concept that has been long forsaken and somewhat forgotten. It examines the way in which the Swedish nobility perceived the politically active peasantry during the 1740s as an expression of the prevailing political culture of the period. The aim of this study is thus to understand a bygone world of thought that once existed in a very turbulent political culture. I focus on the words formed and articulated in the halls and rooms of the Swedish estates by which the thoughts, opinions and power of the Swedish government came to the fore. In doing so it is possible to say something about how the nobility, in their relationship with the peasantry, constructed an object which represented their perception of the Swedish peasant and what this meant.

"Självet" och att bli sig "själv" : Sören Kierkegaards process och reflektion sedd med den positivistiska och negativistiska metoden

What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.

En STARK specialtidskrift : Arbetet med att ta fram en grafisk mall till en specialtidskrift från STARK Magasin, samt en diskussion om hur båda tidskrifterna kan göras om till e-format

The goal with this project was to develop a graphic template for a new magazine about running, STARK Löpning. Besides the looks of the graphic elements, sections in the magazine would be developed. Finally, a discussion is made about how the magazine can be remade into an electronic format.Content analyses has been made regarding magazines with both a main and a specific orientation, to review the graphic relationship between them. A content  analysis regarding a competing magazine about running was also made.An unstructured interview was done with Art Director Petrus Iggström, to find out his way of working when he creates new graphic templates for magazines.The discussion concerning the electronic format was done based on previous research in the subject.The graphic relationship between main and specific magazines turned out to not be significant, they had few similarities. It was often showed that elements regarding the magazine s?identity had been changed, for example text fonts.

Skissen och skissandet - landskapsarkitektens arbetsverktyg

What is sketching for a landscape architect? Does it involve anything else than the sketching process, the tool withwhich we work and carry a project through? The answer is yes, it is a process but one that includes many functionslike making notes in drawings or words for remembrance, a way to convey your ideas to others and to clearifyideas for yourself or together in a group. This thesis aim to give a broader picture of what sketches and sketchingis through many voices, and images made by architects, a psychiatrist, a teacher, and landscape architect students.The focus is on the hand made sketch and show many examples of what a sketch can look like.What is a sketch? A sketch can be many things, but the general consensus is that it is made fast and as a draft. Itcan be made in any material, two or three dimensional.

Termoelektrisk lagring i system med fjärrvärmeproduktion

With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.

Filmiska landskap : film som representation, verktyg och handling i landskapsarkitektur

The title of the final thesis is Filmic landscapes ? film as representation, tool and practice in landscape architecture. The aim of the final thesis is to investigate how film as a medium can be used to describe, interpret and manipulate the understanding of a place and its design. What kind of aspects of landscape architecture can film as a medium in a design-process emphasize or create? How can filming, as a self-standing act, contribute to the understanding of the landscape and a landscape-related design-process? The thesis is divided into two parts, one theoretical part that consists of an essay, and one practical part that consists of a 11minute long filmic reflection of the ?Glass-houses?in Kosta, Sweden, created by the Swedish designer and architect Bruno Mathsson.

Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

Ledarskap inom ramen för ett systemutvecklingsprojekt : fokus på en arbetsprocess med stöd i Vattenfallsmodellen

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.
