Olika kommuner: olika eftervård? En jämförande studie av hur tre kommuner definierar och arbetar med eftervård efter LVM.

Aftercare is an important condition for the Care of Alcoholics and Drug Abuse Act (LVM) to be successful. According to the law, the municipals are responsible for the aftercare. We compared how three municipal in Skåne, Sweden, define and work with the aftercare after treatment under LVM. The study was based on nine qualitative interviews with social workers, division managers and politicians from each municipal. As a theoretical reference the theory of total institutions and empowerment theory were used.

Mätning av abrasivflöde för vattenskärningsmaskiner

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

Styrningens vindlingar: substitutionsbehandlingens premisser

For over 40 years, there's been a debate in Sweden of whether it's good or bad with maintenance therapy for heroin addicts. This method is far more acknowledged in other parts of Europe and in USA. The aim of this paper was to explore how public actors manifest their thoughts concerning the subject of the substitution program in Sweden. This approach includes the complex of problems that can be found in statements and the discourses that these operators stand for and support. In my analysis the philosophical thread was principally based on Michael Foucault ideas, but also on other theories related to social constructionism.

Kan total enteral nutrition ersätta steroidbehandling vid pediatrisk Morbus Crohn?

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can exclusive enteral nutrition replace steroid treatment in pediatric Morbus Crohn?Author: Hanna Rymark Lehnér and Josephine PetterssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012Background: Morbus Crohn is a chronic inflammatory bowel disease which periodically causes great suffering for the patient. There is solid scientific evidence that treatment with steroids effectively induces and preserves remission. However, side effects are many and a great risk for stunted growth and skeletal development exists in children. A widespread view is that exclusive enteral nutrition is as effective as steroids in pediatric Crohn´s.

Produktionsvåtmarker mot övergödning

In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

Uppgradering av biogas i systemperspektiv med avseende på miljöpåverkan och kostnader

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

Likabehandlingsprincipen i uthyrningslagen - om lön för arbetare inom bemanningsbranschen

In Sweden has the temporary agency work industry settled in an explosive way since the deregulation of the unemployment agency monopole in 1993. The demand of civil right for the employer that is rented out confronts the entire labour law regulation with new challenges.The purpose with this paper is an investigation of the principle of equal treatment in The Swedish temporary agency work act and also to create a deeper understanding of the effects of labour and employment relationship. An investigation of relevant collective agreements will be done to highlight the difficulties the principal of equal treatment is exposed to. Further on is there a will to gain understanding for the wage concept and what possible can be included in the wage concept in relation to the principal of equal treatment in The temporary agency work directive. By using the dogmatic method, an approach to descriptive identifying relevant sources of law and clarify the legal situation in the area.In the conclusions it will be determined that the principle of equal treatment in The Swedish temporary agency work act have different effects depending on if the temporary agency or if the client corporation is tied to an collective agreement alternative if a collective agreement is completely missing.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Metodik för detektering av vägåtgärder via tillståndsdata

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

En jämförelse mellan amplifierad singelmolekylanalys och selektiv agar vid kontroll av hygienisering av avloppsslam

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

Phycoremediation of pesticides using microalgae

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.
