Geokemin inom osorterade cirklar : Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil Samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).

Talsyntesen ? Dyslektikerns glasögonoch ett stöd för många läs- och skrivsvaga
According to the National Agency for Education 06-06-2010 are approximately 115 000 students graduating from Secondary School in the year of 2010.Out of these students, we know that thousands of them are hampered by reading and writing disabilities in various degrees. Have these students been given the best support needed when it comes to writing and reading?Compensation may be perceived as a goal for the pupil to catch up with the rest of the educational group or as a vehicle to go round the difficulties. In Sweden, diagnosed dyslexics are not allowed to use speech synthesis, a compensatory technical aid, during the 9th degree national tests.This study?s purpose is to discover if the usage of speech synthesis during the national test of Swedish and reading comprehension might work as a motivation booster for the students and consequently increase their test scores.This is a quantitative study including study including 15 pupils with diagnosed reading and writing disabilities.
Bilden av ledaren - en tolkning av fotografier i årsredovisningar
The visual representation of management (board of directors, chief executive officer and executive management) in annual reports is an area of scholarship that has not been explored much. In the present study a Sample of 87 annual reports from business enterprises within a Swedish context, comprising about 300 photographs, was analyzed using an explorative method of analysis based on semiotics and grounded theory. The influence of the context on images raises a question discussed in the study: Should the photographs in the annual report be categorized as portraits, advertisements and others or should the annual report be regarded as a genre of its own? The photographs showed patterns of homogeneity regarding gender, dress, gestures, colours, pictorial compositions et cetera. The position of the (male) CEO is privileged, but he is also connected to the group through various means like dress and style, thereby further underscoring management as a male enterprise and demonstrating the importance of the suit and necktie in creating homosocial bonds.
Impact by bomas on the distribution of spotted hyena (Crocuta crocuta) in the Mara Region, Kenya
The aim of this study is to find out if, and in what way the Maasai pastoralists affect the spotted hyena (Crocuta crocuta) through Bomas (Maasai settlement) and keeping of livestock. The study was carried out in the Maasai Mara National Reserve and the adjoining group ranch, Koyake GR, in South-western Kenya.Data was assembled through transect driving, with instantaneous scan Sample during two seasons, December 2003 and May-June 2004. Study area contained 12 bomas with three different type of transects each: T1 (0.5 km from boma), T2 (3 km from boma) and T3 (5.5 km from boma), to create a gradual decline in human and livestock impact. Results show that there are differences in the hyena's utilisation of transect type during the day and during the night. The spotted hyena tend to avoid transects close to the boma during the day time, but go there during the night time.
Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid
Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).
De bortglömda barnen : En kvalitativ studie om hur några lärare arbetar med de nyanlända eleverna i den svenska skolan och om de olika undervisningsformerna bidrar till integration
Children of school age, who have just moved to Sweden can either start in a preparation class or in a normal class. There is no Swedish law or national policy that determines how new children will start and continue their education in Swedish schools. The decision is up to the schools or the communes.This study investigates what kind of educational methods teachers, from a Sample of two different schools, are using to educate the newly-arrived students and if these methods are making any contribution to integrating these children into the Swedish school system. The study will raise questions like, how are the new students introduced to the Swedish school, what is the purpose of having the children in preparation class as opposed to normal class, and what methods do the interviewed teachers use to integrate the new children into the school system?Interviews were conducted with four teachers, an associate professor and a senior lecturer in education, who has done several years of research about children from abroad coming in to the Swedish school system.

Den försvunna sången - En studie av en rekonstruktionsprocess
Title: The lost song. A study of a reconstruction process. I was asked by the daughter of the Swedish composer Svea Welander (1898 1985) for help to reconstruct a now lost song for voice and piano originally composed by her mother, where the melody of the song was used in the second movement of her first string quartett. The song was composed in 1955, words by Wilhelm Ekelund. My aim has been to describe the process of reconstructing the song.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Evaluation of an automated multiplex real-time RT-PCR assay for rapid detection of Influenza A and B viruses
Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.
