Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

Att rekonstruera förhistoriska odlingsförutsättningar : första steget i en metodutveckling.

The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..

Det ständigt närvarande svenskämnet : Om högstadieelevers attityder till det språk de använder i andra ämnen än svenska

Film is a tool frequently used by teachers, but it is often limited to showing students how historical time periods looked like, or as a way for students to search for historical inaccuracies. The aim of this essay is to study whether it is possible to use two films based on the legend of Robin Hood as a way to teach students how to contextualize gender history. Through the use of film analysis and gender analysis of two different versions of Robin Hood, The adventures of Robin Hood and Robin Hood: Prince of thieves were analyzed. The study has shown that it is indeed possible to use film as a source material for the study of gender history, and that film can tell us a lot about the contemporary view of gender, masculinity and femininity. The didactical analysis concluded that there was no theoretical objection of using film as a source material; however, there are some things that a teacher should be aware of. Although film may be a good way to create a varied study environment and benefit students with reading- and writing disabilities, there is a risk that time-constraints and lack of knowledge of film and its methodology on, behalf of both teachers and students, may make it hard to implement.

?Gift att dö eller drömmar att leva?

The purpose of this study is, based on theories of gender and hegemonic masculinity, to studyhow masculinity and femininity is constructed and reproduced in one of the most popularSwedish podcast: Filip & Fredriks podcast. The main theory in this study is that gender issocially created and sustained by humans through language and interaction with others.The study's research questions is: How are gender roles/gender portrayed in Filip & Fredrik'spodcast? What characteristics are attributed to men and women in Filip & Fredrik's podcast?How does Filip & Fredrik's podcast represents conditions and power relations between menand women?Through an linguistic textual analysis, which is an application of discourse analysis, I seek toget beneath the surface meanings of texts and examine more implicit social meanings andideologies regarding gender. It includes an analysis of metaphors, word choices and syntax.The analysis shows underlying values and ideologies that indicates gender structures in abroader societal context. Choice of words and metaphores in Filip & Fredriks's podcastexpresses symbolism where men and male-typical attributes are highly valued, whilst womanand female-typical attributes is being devalued and representative of the opposite.Masculinities and femininities are also constructed and represented in various ways throughsentence constructions that guides the listeners in certain directions.

Skolbibliotekariers yrkesidentiteter: En diskursanalys

The aim of this Masters thesis is to identify discourses within the school library field and to analyse which professional identities the discourses result in for school librarians. The empirical data consist of 71 articles from Swedish journals concerning school libraries and school librarians, between the years 2000-2003. The theory and method used is a discourse analysis which is inspired by Ernesto Laclau and Chantal Mouffe. This form of discourse analysis was chosen since it was useful when identity was the focus of study. The analysis is accomplished in three steps.

Ett nedslag i den svenska kriminalvården : Kronobergshäktet i ett institutionellt perspektiv

The purpose of this study is to examine to what extent there is a discrepancy between the formal guiding documents and the employees experiences of the activity at Kronobergshäktet. Furthermore, is it possible that any discrepancy could be explained by institutional imbalance? My main theories are normative institutionalism and a modified type of institutional analysis. The model consists of three parts ?values (a common value-system), rules and practice (the unpredictable reality) and it assumes a reciprocal relationship between them.

Kodväxling och intersubjektivitet  i tolkmedierade domstolsförhandligar

Reaching shared understanding during court hearings is a prerequisite to ensure a fair trial and maintaining legal certainty. Every month between 2,000 and 3,000 court hearings in Sweden make use of interpreters. Interpreter-mediated conversations involve an extra discourse compared to monolingual conversations which increases the risk of misunderstandings.Using methodology of conversation analysis the study explores how bilingualism is expressed during interpreter-mediated court hearings, at which occasions the Spanish-speaking laymen switch to Swedish and what function the codeswitching fulfills. The study identifies patterns in codeswitching and categorizes them into six different types. Furthermore the ideology of monolingualism in court is challenged and the advantages and disadvantages of codeswitching is discussed.The analysis concludes that even though certain types of codeswitching lead to delays in the conversation, the interaction is mostly favored by the Spanish-speaking party understanding some Swedish.

Estimation of reindeer lichen biomass by image analysis

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Den fiktiva läsaren i dagstidningar : En undersökning om skapandet av fiktiva läsare i tre tidningar 1890

This essay researches how newspapers created fictional reader identities through their content. Three newspapers have been studied from the week first to eight of February 1890, Nya Dagligt Allehanda, Dagens Nyheter and Stockholms Nyheter. The question that the essay is attempting to answer is which fictional readers were created. This is done through both a content analysis and a deeper language analysis of the newspapers. The text is seen as an active agent, creating the identity of the reader that they imagine when they write, an ideal reader.

Utvärdering av larmsystem för lageroptimering under trendvariation

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

Utvärdering av beräkningskoden APROS för användning i inneslutningsanalyser

At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.
