Mineraliseringar utmed REE-linjen i sydvästra Bergslagen
This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis.
Skillnader i kommunikationsstil mellan individualistiska och kollektivistiska kulturer
The purpose of this study was to investigate if preferences for high- and low context communication differed significantly between individuals from individualistic and collectivistic cultures, living in a multicultural environment. A quantitative survey was used as method and the survey was answered by 150 students at Jönköping University and Uppsala University. Two self-assessment scales, obtained from previous studies were used to measure the degree of the two cultural dimensions and communication styles. Two multiple regression analyzes were performed to investigate the connection between collectivist cultures preference for high context communication and individualistic cultures preference for low context communication, that has been found in previous studies. Two ANOVAs were also performed to investigate differences in communication style depending on sex and length of stay in Sweden.
Skolan, en arbetsplats att trivas på! : en studie om framgångsrika skolledares syn på lärares psykiska hälsa
Aim and questionsThe aim of our study was to increase knowledge about successful school managers' views on teachers' mental health and their own work regarding this subject.In what ways do the school manager work preventive with measures on teachers' mental health? How does leadership affects teachers' mental health? What factors create mental health among teachers? MethodIn order to answer the questions, we have chosen to use semi-structured interviews. To get in touch with schools that have been successful with their work with the teacher's mental health, we have made a targeted step wise sample where we contacted the primary managers of six randomly selected municipalities in Stockholms län. In total six school managers have been interviewed. The empiric data were thematized and analyzed based on the demand-control-support model. ResultsAll the interviewed school managers agreed to that the concept of mental health is about feeling good, about balance in life and to feel safe.
Innehållsliga och språkliga kvaliteter i relation till betygen : En studie av elevtexter i nationella provet i svenska för årskurs 9
The assessing of student texts is an ordinary and important task for teachers, and the purpose of this study is to investigate, analyze and discuss which aspects of writing that particularly have an effect on the assessment of the student texts. The aspects in focus are: contents, genre, text length, paragraphing, sentence structure and choice of words.The data is drawn from six texts in the national test in Swedish for the 9th grade. Thetexts are analyzed quantitatively and qualitatively regarding contents as well as language.The results show that the qualities of language influence the assessment more than the qualities of contents. Both word variation index and the number of long words increase in relation to raising marks. Uncommon words are also more frequent in texts which receive higher marks.
Rutiner och riktlinjer för förebyggande av smitta på svenska djursjukhus och kliniker
To be able to give optimal care to patients in small animal hospitals, we have to have knowledge about how to prevent the spread of infection. An important part in this is hand hygiene routines. We have to clean hands whenever they are visibly dirty, and disinfect them regularly in between. Another important part is the cleaning and disinfection of the environment in the clinic, and also the cleaning, disinfection and sterilization of medical instruments. Other important parts are isolation of patients with known infections, to wear clothes with short sleeves and to wash them at least once daily, to wear gloves, having short nails and not wearing jewelry when working.
Servostyrning med binaural ljudlokalisering
People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.
Public Sector Scorecard : en ekonomistyrningsmodell med kundfokus
The Public Sector Scorecard (PSS) is a younger version of the balanced scorecard, created for public and nonprofit organizations. The latest model of PSS is divided into three main groups and seven perspectives, while the balanced scorecard consists of four perspectives. Organizations who use either PSS or the balanced scorecard are supposed to have a clear vision spread all over the unit. This study has sought differences between the two models of financial control in both theory and practice. The first part of the study is a theoretical comparison between the models? structures and terms used in them.
Majsensilage i Sverige
Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.
Skolan runt läraren : En undersökning av lärares psykosociala arbetsmiljö i en svensk och en nya zeeländsk skola.
AbstractThe purpose of this thesis is to highlight the organization's importance to teachers' working environment. Through a survey conducted at a primary school in New Zealand and at a primary school in Sweden, teacher perceptions of their psychosocial work environment were compared. This study has answered the questions: ?How does a teacher at a school in New Zealand and at a school in Sweden view their psychosocial work environment from an organizational perspective?? and ?What are the similarities and differences in psychosocial working environment between a school in New Zealand and a school in Sweden?? The results were analyzed based on Karasek and Theorells demands-control-social support model. The study shows that teachers at both schools are experiencing high demands, but that New Zealand teachers are experiencing greater demands.
På spaning efter faktorer som påverkar studietiden vid musikskolor : En enkätundersökning bland rektorer för musik- och kulturskolor
The purpose of this investigation is to see if there is any difference in how long pupils are staying in the activity of the music- and culture schools in the country. I have compared this with how large the teachers engagements are in average at each school, how many teachers each school holds and if one teacher is teaching within different areas, e.g. on different instruments. Thru mail contact with the headmasters at the music- and culture schools I have gathered data concerning the length of which the pupils are staying at the schools, the number of teachers at each school, the size of the teachers services and in how many different areas each teacher is teaching.It has been hard to get to any results in the investigation since the music- and culture schools don?t compile statistics on how long their pupils are staying at their schools.
"Utlämnade i deras händer" : - En kvalitativ studie om hemmets betydelse för personer i hemlöshet
The aim of this study has been to achieve an increased understanding of the meaning of home for people in homelessness. The study is based on texts written by people in homelessness and a qualitative content analysis has been used to process the material. The result has been analysed with an inductive approach, using parts of the analysis method grounded theory. Three aspects of the meaning of home was identified in the texts; control, self-determination and independence. The lack of a home means a major limitation concerning these aspects, according to the texts.
E-böcker på folkbibliotek ? Fokus på prismodell och bestånd
The purpose of this thesis is to explore the situation for ebooksin Swedish public libraries. The background is anincreasing lending of e-books in public libraries, with anacquisition model formed when e-books were more of anexperiment in a few libraries.

Its treatment is time-consuming and associated with many side effects. Therefore alternative forms of treatment, among them omega-3 supplementation, have been investigated. Omega-3 is a family of polyunsaturated fatty acids whose metabolites participate in the regulation of inflammatory reactions in tissues and may therefore have a positive effect on skin symptoms in patients with psoriasis.Objective: To determine if omega-3 supplementation has a beneficial effect on skin symptoms in psoriasis compared to omega-6 supplementation by rating the evidence quality in available studies.Search strategy: The literature search was conducted in the databases PubMed, Scopus and Amed.
Perceptuell och akustisk bedo?mning av ro?stfunktion hos barn med tonsillhypertrofi : Effekter av kirurgi
In Sweden over 10.000 patients annually, mostly children, undergo tonsillar surgery. The most common surgical method is total removal of the tonsil, tonsillectomy (TE). During the last decade partial tonsil resection, tonsillotomy (TT), has been reintroduced and is associated with lower primary morbidity and less postoperative pain. The aim of the present study was to evaluate if and to what extent 4-5 year old children?s voice function are affected by tonsillar hypertrophy compared to controls and to study the effects of the two surgical techniques on vocal function.
