Benskörhet - Osteoporos är en sjukdom som ökat lavinartat. Idag finns ingen bot, även om forskarna har gjort stora framsteg. En vanlig åsikt är att osteoporos är resultatet av förlorad benmassa, vilket inträffar när människan åldras. Har inte individen nått upp till sin optimala mängd benmassa (peak bone mass) under uppväxten, kan de drabbas av osteoporos utan accelererande benförlust Forskarna menar att den enskilde individen kan till en stor del påverka hur skelettet utformas. Syftet med denna litteraturstudie är att sammanställa riskfaktorer och preventiva åtgärder för barns och ungdomars benhälsa.

The health care formulation of the principle of autonomy can be expressed as follows; ?you shall not treat a patient without the informed consent of the patient, or his or her lawfulsurrogate, except in narrowly defined emergencies?. The principle of beneficence refers to a moral obligation to act for the benefit of others. In heath care, the good or benefit in question is the restoration of the health of the patient. In fulfilling this obligation of beneficence, the physician sometimes intentionally overrides the patient?s preferences or actions for the purpose of benefiting the patient.

Purpose: The purpose of this thesis is to investigate whether abnormal stock returns could be identified as a result of a layoff announcement during weak economy.Method: An event study methodology.Theory: Efficient market hypothesis, signal theory.Empirical results: Quantitative data from observations of stock prices in thirty two companies listed on the Nasdaq OMX Stockholm, in the period 2008 -2012.Conclusion: The results indicate that the market reaction was negative because there were negative abnormal returns on the Stockholm Stock Exchange during the period 2008-2012 in connection with the layoff announcements. The market reaction was milder when staff reductions were carried out as a result of a restructuring and stronger when staff reductions were carried out as part of a cost reduction program.The layoff announcements elicited different market reactions depending on the company's industry affiliation. The most negative reaction was in the Healthcare industry. Negative abnormal returns were lower in industries Industrials, Consumer Services and Consumer Goods. There were no abnormal returns for shares of companies in the industry Financials.

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

This paper contains an analysis that sets out to investigate how sustainable development is portrayed in textbooks used in gymnasium level civics education. The study covers three textbooks, all in current use. The paper sets out to explore the relationship between the books chapters on economics and those about environmental issues. The sum of these two parts is in the context supposed to make up the books big picture of green sustainable development, i.e. the ecological aspect of sustainable development. An analytical model will be used to categorise and compare the three textbooks.The method chosen for this is analysis of ideas by use of ideal types.

This paper analyzes governance of cultural and ethnic integration. The study has a comparative perspective between five municipalities in Skåne. One aim in this thesis is to clearify the ratio between the state and municipal authority and how municipalities exercise their autonomy. I analyze the advantages and disadvantages in different governance methods linked to how the municipalities are working in practice and what problem the integration policy is intended to eliminate. I also resolve the influence of officials and citizens in the policy process.My conclusion is that direct ruling to a large extent is limited by indirect control.

Syftet med studien var att belysa hur motivation på arbetsplatsen kan betraktas från ett inre och yttre perspektiv, med utgångspunkt från ett antal specifika faktorer såsom samhörighet, kompetens, autonomi och kontroll i tillvaron. 126 respondenter, 99 kvinnor och 27 män besvarade en enkät som bestod av demografiska frågor, frågor kring chefens stöttande av autonomi, frågor om samhörighet, kompetens och arbetsmotivation samt ett testbatteri bestående av IMI scale, Work Extrinsic and Intrinsic Motivation Scale och Locus of Control. Studiens resultat visar att chefens stöttande av autonomi påverkade de anställdas inre arbetsmotivation positivt. Studien visar även på att det finns ett svagt samband mellan inre arbetsmotivation och tillfredsställelsen av de anställdas behov av autonomi och samhörighetAbstractThe purpose of this study was to see how work place motivation can be seen from an intrinsic and extrinsic perspective, with starting point from specific factors such as relatedness, competence, autonomy and control. The 126 respondents of the study, 99 women and 27 men, answered a questionnaire that consisted of a few demographic questions, questions about if the boss is supportive of autonomy, questions about relatedness, competence and work place motivation.

Alice Lyttkens (1897-1991) was a very popular author in Sweden during several decades in the middle of the twentieth century. She was most famous for her historical novels. During her first period as a novelist in the 1930s, however, she wrote contemporary fiction, reflecting the situation of contemporary Women. The traditional view of the two sexes as ?complementary? permeated the interwar period.

Aim of this work was to determine teachers' ideas about how to encourage lifelong learning in primary school in year 3, so that students can continue learning throughout life. To get answers to my purpose, I used the following questions: What are the teachers' perceptions of the concept of lifelong learning? What are the main aspects teachers emerged as important in education, to encourage students to lifelong learning? Is there potential barriers to teachers for the promotion by the term of lifelong learning?The method used, is qualitative interviews and as a starting point I used the hermeneutic approach. Theoretical part included Ziehes modernity theory of learning and Vygotsky socio-cultural perspective.The results revealed that lifelong learning is interpreted on the basis of active teachers in many varied ways. Teachers' perceptions of the concept of lifelong learning have been very varied.

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Oxytocin is a hormone which plays a crucial role in many reproductive and behavioural functions. It affects many organs and the classical peripheral targets are the mammary glands during lactation and uterus during labour. Oxytocin receptors have recently been described in a variety of normal tissues and primary cell cultures, but also in neoplastic tissues and established neoplastic cell lines, as breast cancer cell lines. The signalling pathways and biological effects of the oxytocin/oxytocin receptor system seem to depend on species, type of tissue, physiological versus neoplastic state and receptor location within the cell membrane.The aim of this project was to find out if the cell proliferation in the canine mammary carcinoma cell line CMT-U27 was affected upon stimulation of oxytocin, and to investigate the presence of oxytocin receptors in these cells. The cell proliferation was examined by using an ELISA-kit, where the absorbance measured is relative to the amount of living cells.

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

Velopharyngeal insufficiency may affect resonance, articulation and thus how speech is perceived by other listeners. Velopharyngeal insufficiency is frequently found in the cleft palate population due to structural abnormalities of the palate. The pharyngeal flap is the most commonly used operation designed to improve velopharyngeal function. The aim of the present study was to compare speech before and after pharyngeal flap surgery by perceptual evaluation regarding nasality, articulation and deviant speech. The study includes preoperative and postoperative speech samples of 28 patients who underwent pharyngeal flap surgery at the University Hospital in Linköping between 2002 and 2007.
