Miljösystemanalys av alternativa avloppssystem i ett urbant område ?Svartvattensystem : Skogaberg ? Ett pilotprojekt i Göteborg
Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.
Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Vindpark Vänern : Fundamentteknik och Logistik
An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Hur de anställda ser på företagskulturen inom MTR Stockholm
Problem: The great interest towards the company?s values has contributed to it becoming more common for individuals to seek out organizations that have a strong corporate culture. Where you work and whom you work for has thus become the dominant factors instead of what you are working with.Purpose: The purpose of this study is to examine how the corporate culture, the rational and emotional benefits are experienced by the employees of the company. The aim is also to examine whether the corporate culture can become a management control measure by good communication between employees within the organization.Methodology: The essay is based on a qualitative research method and empirical data were collected through interviews from the company MTR Stockholm.Theoretical Frame of reference, Edgar Schein, Three Levels of Culture, Seven dimensions.Results: The study has shown that there are different cultures within the company. But also that there is a strong corporate culture within the business, the respondents feel an affinity with working within the underground rather than working for the company MTR Stockholm..
NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
Svenskt och norskt barnavårdsarbete : en jämförande studie av socialtjänstens konkreta barnavårdsarbete
This essay aims to examine and compare Swedish and Norwegian social work with children. It is a comparative study between two social welfare offices, in districts with similar population and problems, one located in Stockholm and one in Oslo. The main questions were; how is the work organized and carried out, what type of help and assistance is available and what kind of discretion and powers do the social workers have. In our essay we used qualitative methods mostly based on interviews, vignette questionnaires and documents, but also written research. In our analysis we used modern organisation theory and street level bureaucracy to seek explanations.The two welfare offices have similarities and differences.
Från plats till plats : informationskoncept för kommunikation och tjänster i Stockholm
Informationskoncept om kommunikation och tjänster för Stockholm Stadsom skall kunna tas i bruk år 2010, året då Stockholm har som mål att varavärldens tillgängligaste stad. Konceptet består av "huvudstationer" vid vilkaman kan genom att peka på en dataskärm får information om hur man tarsig från en plats till en annan. Stationerna är placerade på frekvent besöktaplatser i staden, så som tunnelbanestationer, torg, gallerior, parker mm. Påplatser där det inte rör sig folk i samma utsträckning finns det #mellanstationer#med karta och info om närliggande kommunikationer. För att hittatill respektive #huvudstation# finns även markeringar i marken i form av enpil av metall och glas ur vilken det strålar ljus.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Kollektivtrafikens idé : ägandeförändringar i Stockholms samtrafikhistoria
This thesis is about the idea of public transport and the discussions stirred in the media during changes in ownership. More specifically it is a study of the historical situation of Stockholm, Sweden, where the periods chosen are the 1910s, 1960s and 1990s.During the 1910s Stockholm?s first and largest tram company was taken over by thecity, and a period of public ownership began, which in the 1960s changed form whenthe county council took over the city?s principal authority and formed the politicallyadministered company SL (Storstockholms Lokaltrafik, Greater Stockholm LocalTransit Company). Between these periods the word kollektivtrafik (public transport)was established in the Swedish language. This study describes and compares the ideasconcerning the phenomenon of public transport.The aim of the study is to analyse the ideas, values and ideals concerning public transport in the media, defined as newspapers.
Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter
In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).
