Skolprestationer räknas! : Studie om hur ungdomars skolsituation verkar ha påverkats av multisystemisk terapi

The purpose of this study was to describe the school situation of adolescents who were subject to multisystemic therapy in Sweden, and also if a change could be measured after treatment. Factors that preceded the need for treament were also investigated. The sample consisted of 83 adolescents, boys (65 %) and girls (35 %), with an average age of 14 years. The method used was a secondary data analysis using pre-treatment- and post-treatment data collected from a 7-month follow-up conducted by Lunds Universitet. Results showed that the adolescents were low in school performance and high in truancy at pre-treatment.

Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Samtalsterapi på vårdcentral ? varför, hur och för vem?

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.

Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

Massbalansmodellering av fosfor i ett åländskt kustområde : en utredning om lokaliseringen av Lotsbroverkets utloppsledning

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Den positiva hälsovågen : En kvantitativ studie om hälsofrämjande arbete

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Metadonbehandling : en studie kring två klinikers sociala arbete

The purpose with this essay was to study how the social work is shaped in the methadone programme and how the staffs treat and work with the social integration for the patients.We have studied the experience of a medical assisted treatment from two different treatment clinics and focused on their treatment programme. We have chosen to focus on the social aspect but we have also been taking part of the medical treatment - the methadone. In order to get a bigger picture of our problem area we also studied how Sweden's narcotic politic is constructed and how a narcotic life could look like before the entrance in the program. We describe this with the help of the theory about the narcotic carrer and the society's view on a normal living..

Arbete mot mobbning innom skolan - följs kommunens riktlinjer?

AbstractThe purpose of this research is to examine which methods the municipality of Örebro recommends its schools to use in their work against mobbing and bad treatment, and to see if the school investigated follows these guidelines. By means of interviews I will examine which methods the Group for Equal Treatment at the school has found effective when dealing with these issues. My conclusions are that the municipality of Örebro clearly states what is important for the schools to work with, and a lot of effort has been put into creating a common model for all schools to use, in order to fulfill the goals of the law (2006:67) which forbids discrimination and any other kind of bad treatment of children and students. The school investigated follows the municipality guidelines to great extent. Early on the Group for Equal Treatment, including both principals, teachers and students, worked out a detailed plan for equal treatment. The Group for Equal Treatment mentioned some successful methods to use against mobbing and other forms of bad treatment. One of these methods is the annual theme week where the students get to participate in outlining the contents. Another success factor is to establish a good atmosphere between teachers and students, which is possible only if the teachers have time and opportunity to get to know their students. My examination shows that it is important to have a well thought-out plan to follow, but it must be adjusted to the needs and preconditions of the school in question..

Lillån : Statusbedömning enligt EU:s ramdirektiv för vatten

In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.

Rökgaskondensering : Ett möjligt alternativ för Nybro Energi AB?

Syftet med undersökningen var att klargöra om en rökgaskondensor är en bra investering för Nybro Energi AB. Saxlund Bioenergy AB kontaktades för sammanställning av offert. Med hjälp av parametrar från Nybro Energi AB och offerten från Saxlund Bioenergy AB, gjordes beräkningar för att avgöra om en investering är lönsam. Resultatet av undersökningen visade att en investering av sådant slag som behandlats i detta arbete var intjänad efter mindre än sju år i drift och effekten som är möjlig att utvinna uppgår till 2,8 MW, förutsatt att panneffekten utgjordes av minst 15 MW.  Slutsatserna var att investeringen inte var betald efter sju år med underlag av att kostnader som utgjordes av eventuell ombyggnation inte var behandlade i undersökningen, detta innebar dock inte att en investering ärr olönsam då dessa kostnader uppskattades som små i förhållande till den totala besparingen efter att den ekonomiska livslängden på 15 år har löpt ut..

Mobbning och kränkande behandling : En undersökning om skolors förebyggande arbete mot mobbning och kränkande behandling

The purpose of the work is to highlight schools work to prevent bullying and abusive treatment, find out about schools work to prevent bullying and abusive treatment follow what is written in the governing documents and how schools can work preventively against the same. The questions have been investigated through qualitative interviews and analysis of documents or in the theoretical background. The interviewees and partially schools were selected through an arbitrarily selection. In each plan against abusive treatment states that the monitoring and evaluation should be conducted in a manner that is not consistent with the responses from leisure educator 1, 2 and 3. School B's plan does not contain an overview of the measures needed to prevent and stop abusive treatment of children.

Förbättring av den svenska kiselalgsmetoden-hantering av sedimentering

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.
