The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.

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..

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

This essay is about how working with children with autism works with the laws and regulations that fall under the Compulsory School Ordinance and Lgr11 (Compulsory for primary school, preschool classes and kindergarten). The aim of this work was to examine various educators thoughts, experiences and practices related to children with autism in primary school. The study is based on three questions: what kind of rights regarding support do children with autism have in the Swedish primary school, according to the primary regulation and Lgr11? How do the selected primary schools work with the support of children with the diagnosis of autism? And how well does the affected educator?s think that the support works?To answer these questions, four qualitative interviews with various educators, were made. My results show that all four educators believe that inclusive labor of children with autism is a good thing for everyone, as long as it is done properly and with the right order, so that the child with autism gets the opportunity to be part of a social group.

The purpose of my study was to visualize how teachers works with multilingual children in pre-school, the methods used to stimulate and develop primary and secondary language and how teachers does see second languages development with the help of the primary language. The study consists of qualitative methods in form of interviews which are made with four teachers who work within the pre-school. The findings during the collection of data (interviews) are going to be connected to the relevant literature on the subject I have chosen.The result showed that the concrete materials are used to stimulate and develop primary- as the secondary language and that the teachers have different opinions on secondary languages development with the help of primary language even if the primary language seems to be an important asset of all teachers that I interviewed..

The aim with this thesis was to study how primary school teachers perceive their mission in working with inclusive education. The aim was also to study their thoughts and experience of the Special education support. To conduct the inquiry twelve primary school teachers from two different communities in Sweden were asked to give their views of inclusive education. The central issues was how the primary school teachers interprets the concept of inclusion, the opportunities and obstacles they perceived and how the Special education support was formed in the work with inclusion in their schools. The result shows that the majority part of the primary teachers interprets the concept as a spatial or social inclusion.

The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Approximately one third of all patients in primary care have a psychosocial component to their illness that requires adequate professional treatment. However, primary care is insufficiently prepared for these patients. The aim of this case-study was to evaluate a pilot project in primary care offering psychotherapy as a treatment alternative. The data collected includes 1) data from 352 referred patients regarding demographics, diagnosis, treatment duration and pre- and post health status, 2) a patient-satisfaction questionnaire and 3) interviews with six therapists and five medical doctors. The treated patients improved significantly and showed a high degree of satisfaction.

ABSTRACTBackgroundPostpartum depression (PPD) occurs in 10% of women who have recently given birth. Postpartum depression is treatable but unidentified and untreated it could lead to serious consequences. There are multiple instruments for screening available. The Edinburgh Postnatal Depression Scale is the most frequently used and is regarded as the best instrument. AimThe aim of this study was to analyze to what extent and how midwifes and primary care nurses identify mothers with symptoms of depression respectively PPD.

Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

The aim of the thesis is to present a study of what works well and what does not work so well in today?s use of computers in primary care with a special focus on the use of computers in the management of referrals for consultation. In May 2009 a module for electronic consultation referrals was introduced in the computer system Cosmic at the University Hospital in Uppsala. Previously, the primary care units had to use two different systems for management of referrals. Referrals sent internally within primary care have been sent electronically while referrals to the University Hospital or other external units were sent on paper.
