This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

The purpose of this paper is to investigate when Swedish and English are used in English teaching and how the pupils view the importance of the classroom language for their language development. My research questions are ?In what situations is Swedish and English respectively spoken during the English lessons?? and ?What are the pupils' opinions concerning the significance of English and Swedish in the classroom for their language development??. To answer my questions, I have used relevant theoretical research and conducted two observations and two group interviews in a secondary school. The observations have given me an example of how it can function in the classroom and the interviews have given me the opportunity to hear the pupils' different perspectives on how it is done in the classroom and their different opinions concerning this matter. According to the research, it is of great importance that the pupils are offered the opportunity to use the English language as much as possible in the classroom.

Den här kvalitativa studien syftar till att ge en bild av vilka uppgifter lärare utför mellan sina lektioner. Lärare tillbringar inte hela sin arbetsdag i klassrummet, utan en stor del ägnas åt andra aktiviteter än undervisning. Denna del av arbetet är dold för många utomstående och får därför inte samma uppmärksamhet som lektionstiden med eleverna. För att samla in material har åtta gymnasielärare ombetts föra loggböcker över sina aktiviteter utanför klassrummet under två veckor. Resultatet visar på en stor variation när det gäller olika uppgifters karaktär och frekvens.

Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.

Arbetets syfte är att undersöka hur högstadieelever för matematiskt resonemang. De frågeställningar som studien inriktas på är vilka lösningsstrategier elever väljer då de resonerar matematiskt såväl som vad  det finns för skillnader och likheter mellan de yngre elevernas lösningar och de äldre elevernas lösningar.Undersökningen genomfördes i två klasser, den ena i årskurs 8 och den andra i årskurs 9, på en grundskola. Eleverna fick lösa uppgifter, vilka uppmanade dem att föra matematiskt resonemang, individuellt. Resultatet av studien visar att majoriteten av undersökta elever har valt att resonera deduktivt. Jämförelsen av elevers lösningar i två årskurser visar att årskurs 9 elevers resonemangsföring präglas av större förtrogenhet med den algebraiska demonstrationen.

Teaching materials are a constant matter of discussion as they represent the school curriculum and what the students are reading in the classroom. Within religious studies in upper secondary school, a new approach emerged since the new curriculum from 2011, which is to interpret religion in relation to gender. This study aimed to see which gender performances two selected teaching materials represented, in both their texts and images. This study was performed using both discourse analysis for the texts and content analysis of the images. The study showed that traditional gender performances appear both in the chapters that touched human identity and also ethics and morals, and also in the chapters that touched the world religions.

It is important that the language in textbooks for foreign language learners reflects the language that the learners would encounter in real life. For this reason, the presence of the thousand most common nouns in two Swedish textbooks in Spanish for upper secondary school is observed in this study. Furthermore, this study aims to examine how these nouns occur in order to determine if their pattern of occurence favours the learning and consolidation of words. The main materials that have been used are A Frequency Dictionary of Spanish by Davies (2006) and the word search program available in the digital versions of the textbooks. The results show that the presence of the thousand most common Spanish nouns does reflect the frequency information presented in the frequency dictionary but not all thousand nouns are included.

This research paper has examined how three teachers in a Swedish state secondary school adapt their teaching to immigrant pupils aged 13 to16 who have recently arrived in the country. The study is based on observation in the classroom and interviews with the teachers. The study showed that all the teachers adapted their teaching methods in the different subjects by actively working with language development during their lessons. The methods employed included explaining words and definitions, using visual methods of teaching and setting frequent written exercises. In this way the pupils developed their language skills whilst covering the subject coursework.

It could be argued that theories about gender are something that should be a part of every upper secondary school teachers agenda (knowledge base), because the Swedish curriculum specifically says that schools must encourage and work for equal rights between men and women.The students are supposed tobe encouraged to develop their interest, without judgment, about what femininity and masculinity is.This essay is aiming to find out how gender is used in the teacher program at Södertörns Högskola. The main focus of the essay is to see the possible differences between the curriculum of 2010 and 2013. Using quantitative and qualitative content analysis this essay is aiming to examine how gender words are used in the syllabus, study manuals and literature lists for Educational science A (2010) and Educational science I (2013). In what way are gendered terms, like boy, girl heterosexuality and man, part of the text material? Who is represented in the material? And are there any differences between 2010 and 2013?The results show that there is a difference.

Huvudsyftet med denna studie är att kartlägga vilka faktorer som påverkar i gymnasievalet. Frågeställningar som belyses är vilka faktorer som påverkar eleverna och vilka personer som är betydelsefulla. I studien diskuteras också skillnader mellan olika grupper som exempelvis kön. Metoden som valdes var enkätundersökning med elever i årskurs 9 som stod inför sitt gymnasieval. Resultatet visar att intresse och att programmet ska förbereda för högre studier är de faktorer som påverkar mest.

Next year, Swedish upper secondary school will be the arena for a new comprehensive reform according to an extensive government bill. The reform will probably have major impact on every-day educational practices. The aim of this paper is to describe the consequences forbiology teaching when the reform is implemented, and to analyse in what way the biology teachers, and other participants, take part in digitised discussion forums during the implementation of the reform.The research design consists of a quantitative approach and two different methods are used, i.e. descriptive content analysis and quantitative content analysis. The content and meaning of the government bill is analysed and the statements from the participants at the discussion forums are equally important in order to fulfil the aim of this inquiry.The results show the reform will have a profound impact on the subject biology, e.g.

While almost 23 percent of the students in the Swedish upper secondary school are foreigners, only a fraction of the school libraries? collections consists of literature written in other languages than Swedish or English. This study examines how five school librarians experience the task of working with literature composed in foreign languages in the multicultural and multilingual school of today. The results of the qualitative interviews are analyzed in relation to the legislation and policy documents that the school libraries are working by, and also in relation to the theoretical framework of sociocultural theory and the theories on second language acquisition developed by linguist Jim Cummins.The study shows that while multilingualism is discussed as an important matter in the legislation and policy documents that the school libraries work by, the librarians in this study largely view the question of foreign literature as peripheral. Most part of the librarians connects first language reading to leisure-time activities rather than curricular activities, and stresses that the Swedish language should be prioritized in Swedish schools.
