Rening av avloppsvatten från biltvättar med filter av torv och inblandad kolaska : en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv
Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns..
Experiences in enabling elderly people for communion and solitude in a South African context
Aim: The aim of this study was to explore the care providers' experiences in enabling communionship and solitude in daily living for elderly living in old age homes in a South African context. Method: This study was done using a qualitative analysing method, with empirical data obtained from nursing staff of elderly. The study was phenomenological which aims at deepen the understanding of human experiences as phenomenon. The data was collected by using a groupinterview which included five informants from an old age home in Pretoria. The analysis included two steps; Naive reading and structural analysis in order to transform the individual elucidations into an abstract which had no individual touch.
Hur påverkar naturvårdsåtgärder mängden av vedlevande insekter : Manuellt dödade träd vs självdöda
Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

Tjackhoran - finns hon? : en studie av föreställningar om den amfetaminmissbrukande kvinnan
The object of this study is the female user of amphetamines and the characteristica which she is often described by. Many of these descriptions regard the female amphetamine user's sexuality which also have come to form the assumption that these women make a living from having sexual relations with men in exchange of drugs.In order to be able to draw any kind of conclusions regarding this, we found it necessary to investigate how the stereotypical female user of amphetamines makes a living and also whether it is possible for a female drug user to decide for her self how to support her habit.The disposition is a qualitative study of literature and the perspectives that we focused on in this study are gender roles, relationships and sexuality, criminality and finally the drug using woman as a victim. The theories used deal with social constructivism, respectability and shame.The main discussion of our study has been how women amphetamine users are moulded to become victims through interaction with other people but also with the society as a whole..
Sticklingsetablering av Sedum spp. för gröna tak : biokol som organiskt material i substrat
The popularity of vegetated, or green roofs, has grown over the past years due to their potential
function of maintaining urban environment quality. The aim of this study was to investigate if
substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%)
influenced the growth of the cuttings during the first critical period of the establishment. Biochar is
used as amendment to agricultural soils and has, theoretically, many of the properties suitable as
organic content in green roof-substrates. Peat is one of the materials that is commercially used in
green roof industry. The substrate has been treated with different amounts of water.
Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder
The mining industry, in terms of ore excavation and metal production, is and has been
important to the Swedish economy. In connection with the ore excavation process, large
amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage
(AMD). This water may reach the nearest surroundings and cause negative environmental
effects. By covering the waste with soil or water, the oxidation process can be minimised.
At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between
1951 and 1991.
Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening
The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.
Samiska kvinnors levnadsvillkor i kulturen och rennäringen
Previous research often includes juridical, political, economical and historical aspects of the Sami population. The research about the Sami women are limited therefore is was important to investigate the living conditions of the Sami women. The purpose with the study was to investigate the living conditions of the Sami women from a culture- and reindeer-herding view in relation to social gender and the majority society. Four individual interviews were performed with women who worked with reindeer-herding in the Sapmi area in north of Sweden. The interview guide was semi-structured and the data were analysed with the phenomenological method Interpretative Phenomenological Analysis, which has a focus on subjective experiences.
Vaddå ekonomisk utsatt? : Tankar om ekonomisk utsatthet bland barnfamiljer med utländsk bakgrund i Växjö kommun
AbstractThis thesis is centered on the economic condition and background of immigrants living in Sweden, with focus on Araby, Växjö. To guide us through this enormous work we formulated research questions, which are:Why have foreigners (immigrants) a greater risk of becoming economic vulnerable? How does economic vulnerability effect families with children?What strategies do families adopt under hard economic conditions? What strategies does the society adopt in assisting families, by economic aid, that are economic vulnerable? Our sample was from a school where we administered an open ended questionnaire to selected students and we also had a comprehensive interview session with ten families in the community so as to have a complete picture of their living condition and how they think people are economically vulnerable.We concentrated on the causes, consequences and strategies of how economic vulnerability is handled by immigrants in Sweden. In our analysis we found out, though our respondents? answers, that the causes of economic vulnerable are background, language, priorities et cetera.

Beräkningsmodell för massbalanser för Slottshagens reningsverk
In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..
