Masugnsslaggens potential som filtermaterial för metaller i vägdagvatten
Dagvatten från vägar innehåller ofta tungmetaller. De vanligaste metallerna i vägdagvatten är bly, koppar, kadmium, nickel och zink. Dessa föroreningar utgör en belastning i recipienter som tar emot dagvattnet. I denna rapport har bly, koppar och zink reducerats från vägdagvatten genom filtrering i kolonner med amorf, granulerad masugnsslagg och sand. Masugnsslagg, som är en biprodukt från framställningen av järn, är en alkalisk produkt med goda sorptionsegenskaper vilket gör den lämplig att använda som filtermaterial för vatten förorenade med metaller.

Interventioner som avser att förbättra placerade barns skolprestationer : En kunskapsöversikt
The educational underachievement of children in foster care has been known for a long time. This study aimed to compile and analyze the current knowledge about interventions, intended to improve foster children?s school achievements. The method used was a systematically undertaken narrative review. Despite a comprehensive searching strategy, only ten relevant studies were found, indicating that little has been done to improve the educational outcomes for children in public care.
The WT1-gene ? its role in tumourigenesis and prospects for developing a vaccine
The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).
Humanitär intervention och suveränitetsprincipen : En studie om huruvida stater har påverkats av framtagandet av "responsibility to protect".
The reason behind this essay has been to study if previous research is relevant for Jehovah?s Witnesses in Sweden and see if secularization has affected the organization or not. The empirical material is made from two qualitative group- interviews and open observations during two meetings in the Kingdom Hall. These studies were performed in Oskarshamn and Mönsterås during the month of February. The reason that these studies have been limited to Oskarshamn and Mönsterås is mainly because they were the only ones willing to do an interview. According to previous research by James A.
Media, en ignorerad länk i den strategiska berättelsen : En kvantitativ studie över medias projektion av det svenska Afghanistannarrativet
The Afghan war post 9/11 has become the source of multiple case studies. Recent studies suggest that variations in domestic support for deployment of troops in Afghanistan can be explained by means of the strategic narratives provided by the policymakers of the contributing state; a strong consistent narrative increases public support. Scholars recognize a Swedish catch-all narrative, which suggests weakens the narrative, thus raising the uncertainty among the public. This thesis investigates the projection of Swedish strategic narrative through elite Swedish newspapers. The content analysis reveals an inconsistency between the policymaker?s formation of the strategic narrative and the narrative projected by individual newspapers.
En studie om assyriska/syrianska ungdomars språkbruk och språkidentiteter
Gender is a universal factor that is unavoidable in classroom interaction between pupils and teachers. The principle aim of this essay is to illustrate whether, during the interaction between pupil and teachers still occurs behavior that expresses a gender order. We also want to establish if the ones who attract attention from the teachers is the individual, or if teachers still on a subconscious or conscious level, think of the pupils gender and ascribes him or her some characteristics or qualities. Especially we want to bring out the pupils thoughts and sights of there is a difference on how teachers treat boys and girls. Another purpose we wanted to achieve was to illustrate how teachers work with the concept of equivalence between the sexes, according to Lpo94.Our essay is built on our studies around what teachers think on how they treat the pupils, on the basis of gender perspective.
GRÖNYTEFAKTOR I ETT NYTT PERSPEKTIV - Går ekosystemtjänster att mäta med fjärranalys?
Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.
Cykelolyckor i korsningar : Hur kan trafiksäkerheten förbättras?
Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The purpose of this paper is to highlight bicycle accidents at intersections and to suggest improvements in three accident-prone junctions in Stockholm. This is achieved by the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.

Hastighetsreduktion på genomfartsleder, genom icke-tvingande åtgärder i vägmiljön
The study was conducted with an landscape approach with an subject related approach in the field of environmental psychology to investigate how road design affects drivers' choice of speed. The purpose was to portray road environments on thoroughfares in urban areas to motivate motorists to keep the speed limit and thus increase road safety for vulnerable road users. The task question was formulated, how can thoroughfares in suburban settings be portrayed to motivate motorists to reduce speed?
The study was conducted throughout a literature review of motivational speed measures along with interviews with road design experts at the Swedish Transport Administration. Case studies were conducted on three thoroughfares in the Stockholm suburbs Vallentuna, Upplands Väsby and Danderyd.
Finanskrisens påverkan på konkursprediktion
Prior research on the ability of financial ratios to predict bankruptcies has shown a significant difference between the companies that went into bankruptcy and those that survived. This paper investigates whether there is a difference in the prediction ability of financial ratios during the last financial crisis compared to relatively normal macroeconomic environments in which most previous studies have been conducted. We use univariate analysis to compare companies that went into bankruptcy during 2010 and 2011 with companies that remained active. Our dataset consists of 51 failed companies that are matched with 102 companies that remained active. All companies were Swedish limited companies with more than 50 employees and the comparison is made with 26 financial ratios.
Flerkanalspublicering och dess påverkan på journalisters arbetssituation : en studie av flerkanalspublicering i olika stadier
Purpose/Aim: The aim of this thesis was to examine how multi channel publishing in different stages effect the work for journalists.Material/Method: The thesis is based on ten case studies selected from the literature and one conducted especially for this thesis. The case studies have been categorized according to a model that describes three strategies for multi channel publishing. The first strategy is to have a primary publishing channel, the second is to have separate editorial staffs for all publishing channels and the third is to treat all publishing channels equally.Main results: Journalists working for companies using the first strategy have not experienced any major differences in working conditions or work practices. For journalists employed by companies using the second strategy for multi channel publishing the effects on the journalists was noticeable but not major. The effects on journalists in companies using the third strategy are mainly stress and an uncertainty regarding how to use special media techniques..

?Jag kan inte se att vi behandlar elever olika beroende på kön? : en kvalitativ studie om fem SO-lärares tankar om sitt uppdrag avseende jämställdhet, kön och genus i undervisningen och i sitt bemötande av elever
This paper attempts to display how five teachers of social studies use and relate to the policy documents and their instructions on gender. To penetrate the subject, five teachers were intreviewed. Each interview focused on how the curriculum attempts to guide teachers regarding gender, sex differences and equality of opportunity. The collected information was processed, analyzed and discussed using gender studies and discourse theory.The results show that the interpretation and usage of the curriculum is very subjective and varies greatly between all the interviewed teachers. Their personal interpretation proves to be crucial when it comes to making reality of the stated goals in the curriculum, concerning actively working towards equality of opportunity between sexes.
