During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

 Conclusion:Medical treatment may have a role in platelet count after transfusion. Since the TACSI platelets passed the quality requirements, and the vast majority of patients platelet count increased after TACSI platelet transfusion, the TACSI platelets will replace the old method to produce platelets at the Uppsala University hospital.  Methods: A new approach that pools 8 buffy coats (TACSI platelets) that were separated into 2 units instead of 4-6 buffy coats pooled to 1 unit was investigated in this study. After the platelets were extracted from the buffy coats their quality was controlled and subsequently the platelet product was evaluated in 96 patients. Results: The results showed that 80 % of the platelet units passed the European quality requirements. Further, the platelet count was increased in most patients that received TACSI platelets. Conclusion: Medical treatment may have a role in platelet count after transfusion.

Dataspelsproblematik är ett eskalerande problem som har visat sig påverka många unga människors utveckling och välbefinnande. Syftet med denna studie var därför att undersöka ungas dataspelsproblematik, vilka konsekvenser ett överdrivet dataspelande medför samt vilken behandling som ges till unga med dataspelsproblematik. Empirin erhölls genom kvalitativa intervjuer med professionella som arbetar med denna typ av problematik vid verksamheterna Game Over och Theory in Action. Resultatet visade att dataspelsproblematik idag inte har en bestämd definition och att det är ett problem som inte är tillräckligt uppmärksammat. Synen på orsaker till dataspelsproblematik hos unga är komplext då det kan tänkas bero på många olika faktorer.

Type 2 diabetes is a growing disease in the population which includes that older people are a risk group. With the disease grows even cost?s. A lifestyle change is a major part of the treatment for type 2 diabetes. There are several factors that suggest positive effects on prevention among the elderly where, among other things, economic and health benefits are presented.

The purpose of this paper was to examine how clients on the unit for adults at Södemalms district administration (Stockholm, Sweden) with severe mental illness and substance abuse differs from other clients with substance abuse at the baseline and at follow-up one year later. We have used a quantitative method and analyzed material from ASI-interviews performed at the adult drug abuse unit at Södermalm during the time period 2002-2010. At the baseline the clients with substance abuse and co-occurring severe mental illness have more problems than other clients, primarily in the area of mental health. They spend more time alone and are more likely to engage in illegal activities. Interviewers assess their situation as more serious and that they need more help in all of ASI's areas of life than other clients.

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Ämnet för denna uppsats är tillsynen av enskilda hvb-hemför minderåriga. Syftet är att titta närmare på hur denna tillsyn egentligen fungerar i tre valda län ? Örebro, Halland och Skåne. Uppsatsens huvudfråga handlar om hur tillsynen går till, om riktlinjer finns samt om dessa efterföljs. Uppsatsen har en explorativ ansats och informationhar sökts främst genom e-post-kontakt med olika instanser men också via Internet och litteratur.Det har visat sig att tillsynen oftast följer framtagna riktlinjer i någon form, att den sker via föranmälda besök på hvb-hemmen där tillsynsmännen tittar på dokumentation, rutiner,personal samt behandlingsarbetet.

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

The aim of this study is to gain an understanding of former criminals' own experience of their entry into criminality and to identify and analyze the factors they use to explain their path into criminality. To study this area, a qualitative method has been applied with five semi-structured interviews of ex-criminals from an organization that works to help and support people who have previously been involved in crime by offering employment, education, and rehabilitation in order to be further integrated into society again. To analyze the respondents' stories about their way into criminality, the theory of social bond by Hirschi has been applied and contribute with insights in later criminal acts as well as the theory has been problematized to some extent. Today, there is a lot of research on different aspects that can explain the way into criminality in different aspects, on the other hand, research has largely been measured with a quantitative approach with statistics and self-reported data. This study therefore intends to apply a qualitative approach, where ex-criminals themselves describe their path into criminality.

  ?this Unpleasent klientel?A study on refugee care in Växjö between the years 1944 and 1947.The purpose of this study was to examine the treatment of sick refugees in Växjö in the 1940s. To achieve this a combination of quantitative and qualitative methods were used. The material found in the local archive and local newspaper was then put together and analyzed from the theoretical perspective, gender, class, ethnicity and social status.The result of this study shows that there were two main treatment wards for refugees, one that was supposed to treat women and children with active tuberculosis and the other ward treated refuges with ?epidemic diseases.? Foreign citizens were also taken care of in other words that were also not meant for refugees only, like the Epidemic hospital, which treated about 80 patients of a foreign nationality between 1944 and 1946.

Background: In scientific literature there are various treatment programs for people with alcohol dependence described, however, are psychosocial factors that promote recovery process described to a limited extent.Purpose: To describe the psychosocial factors that promotes recovery from alcohol dependence.Method: Literature study of ten scientific articles, published between 1999-2011 with both qualitative and quantitative design.Results: According to the literature, the recovery process can be considered to begin when a person with alcohol dependence reached his personal rock bottom. The longer the recovery progresses, the greater are the overall level of performance. Social support is described as an important factor to prevent relapse and reduce the need for professional help. Self-belief and support of self-help groups are described as important to maintaining sobriety. Social support and influence from family members was related to increased ability to analyze and assess their situation during the recovery.

Title: The nurse's dilemma in psychiatric inpatient care - a balancing act between good and evil Objective: To describe the nurse's experience of relieving patient suffering caused by coercive measures on a closed psychiatric ward . Frame of reference : The results are discussed in light of Eriksson´s theory of suffering and caring relationships Method: A qualitative analysis based on focus group discussions Results: The analysis resulted in six categories, to protect the patient , to involve the patient , not to lose control , to remain , to justify compulsion , and to be touched . The results showed that nurses had the experience of being able to relieve the suffering of patients caused by coercive measures. It was also found that the nurses had a tendency to justify coercive measures , the more experience they had of performing these . Conclusion: The results describe that nurses have the experience and knowledge of how to relieve patients' suffering caused by coercion but also their experiences of performing these .
