As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. Here the parameters solar radiation, temperature, humidity, emission factors and background concentrations of gaseous a
Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. Lösningen är syntetiserade TEM bilder som baserats på projektioner av numeriskt simulerade aggregaIn this master’s thesis a method for estimating the fractal dimension from Transmission Electron Microscope (TEM) images of soot aggregates has been developed, and also applied to TEM images of soot sampled from a mini-CAST soot generator. The problem to estimate the fractal dimension, a 3D property, from a 2D image is undetermined. To solve this, TEM images were synthesised based on projections o
In Stockholm, Sweden commuters are spending 17 working days a year stuck in traffic, polluting our climate and wasting their time. Commute by train could be a great replacement if the connections to the stations were not lacking. By adding the adult kick bike Pendla to the train you will be more flexible, healthy and eco friendly. The kick bike is foldable and free to bring on the train. My produc
Denna uppsats är en kvalitativ aktionsstudie som genom intervjuer undersöker hur lärare och elever på ett estetiskt program resonerar kring och definierar begreppet “personligt uttryck” samt vad de tänker ska utföras för att uppfylla kunskapskravet innehållande begreppet. Detta i syfte att öka kunskapen i huruvida samsyn råder eller inte, öka förståelsen kring hur eleverna definierar och resonerarThis essay is a qualitative action study that through interviews studies how teachers and students in an aesthetics program in highschool defines and thinks about the term “personal expression” and what the student should do to meet the expectations for fulfilling the requirements concerning that particular grade. The purpose is to increase the knowledge about what differences and similarities the
As environmental awareness is raised, flue gas treatment is gaining more interest and stricter legislation on emissions pushes technological development. Sysav has a waste incineration plant with a flue gas cleaning process which includes removal of acid gases. This is performed by two subsequent scrubbers and following each scrubber a droplet separator is located to prevent transfer of liquid to
Våld i nära relationer är ett globalt problem som förekommer i alla kontexter. För att kunna bemöta utsatta och förövare är det väsentligt att yrkesverksamma, så som socionomer, psykologer och sjuksköterskor, har tillräckligt god kunskap och kompetens rörande ämnet. Den aktuella studien syftade till att undersöka yrkesverksammas syn på sin kunskap och kompetens rörande våld i nära relationer utifrIntimate partner violence (IPV) is a global issue which occurs in all contexts. In order to help victims and perpetrators of IPV it is essential that professionals, such as social workers, psychologists and nurses, have sufficient knowledge and competence regarding the issue. The current study aimed to examine professionals’ view of their knowledge and competence regarding IPV based on the factors
The aim of this study was to examine international adoptees' reflections of the own ethnic identity. Through semi-structured interviews, six adult adoptees shared their experiences from their childhood and the present concerning identity. Five different themes were used in the interviews to discuss identity; reflections of the self, interactions with the adoptive family, interactions with same
As the processes of globalization intensify, the issues of people migration and citizenship receive more scholarly attention than ever. The questions regarding dual or even multiple citizenship are unavoidable nowadays and governments have to decide whether they tolerate the fact that their citizens may also be citizens of another state or do they prevent their citizens from acquiring multiple cit
Since January 2013 a new archival description system applies to all government agencies in Sweden. The system, developed by the Swedish National Archives, is based on the actual records and the organizational processes from which they originate and has been implemented since the guidelines RA-FS 2008:4 came into effect in 2009. In order to better understand the process oriented archival descripti

Purpose: Study if and how personnel-intensity affects companies' post acquisition stock performance Methodology: Quantitative study of 90 american companies that in 2007 made acquisition deals worth over $100 MUSD. An event window of five days was used, and comparisons between industries were done to find correlation between personnel-intensity and performance. Theoretical Perspectives: Based
An improved, chemoselective hydrogenolysis method has been developed. By employing a solvent-acid combination (i.e., DMF-aq HCl) we were able to favor debenzylation rather than aromatic hydrogenation and acid-mediated bond cleavage which are the two main drawbacks of these reactions. The generality of the method, which was primarily developed as a solution to a carbohydrate problem, is shown by th
Bruton's tyrosine kinase (Btk) is a nonreceptor tyrosine kinase, critical for B-cell development and function. Mutations that inactivate this kinase were found in families with X-linked agammaglobulinaemia (XLA). In this study the Btk gene was analyzed in 13 registered Greek patients with XLA phenotype originated from 12 unrelated families, in order to provide a definite diagnosis of the XLA. The
