Behandlingsmetoder vid iliotibialt friktionssyndrom: En litteraturstudie
Iliotibialt friktions syndrom (ITFS) är en av de vanligaste överbelastningsskadorna som drabbar knäet. Traditionellt har skadan betraktats som ett friktionssyndrom, senare studier har dock hävdat att en kompression av underliggande fettvävnad är orsaken till diagnosen. Etiologin och patologin bakom diagnosen har därmed inte kunnat fastställas. Kliniskt tillämpas stretching, styrketräning av höftabuktorer, neuromuskulär korrigering och myofaschiella behandlingsmetoder i rehabiliteringen av ITFS. Syftet med denna litteraturstudie var att sammanställa det vetenskapliga underlaget för behandlingsmetoder vid iliotibialt friktions syndrom.
Composition of fractions from air-classified wheat flour
The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.
En annan värld? En analys av sex fantasyromaner ur ett genusperspektiv
The aim of this Master?s thesis is to examine how the gender system is described in fantasy novels. The theoretical framework is based on Yvonne Hirdman?s theory on gender system, primarily the two basic principles: the principle of dichotomy, of separation between the sexes, and the principle of hierarchy, of man as norm. The method used is idea analysis which is a form of textual analysis.
Tätning eller ventilering mot fukt på kalla vindsutrymmen
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
Fyra uppdrag om människokroppen för grundskolans senare år
Recent studies show that the knowledge in and understanding of science, technology andmathematics of Swedish junior high school and high school students is decreasing. As a resultof this the Swedish government has initialized several studies, research and reforms. One ofthe theories for teaching that today is seen as effective is the socio-cultural perspective and itsdescendants, including scientific inquiry. Using the pedagogy of the socio-cultural perspectivefour assignments regarding the human body was constructed for junior high school studentsattending summer research school in the summer of 2008, hosted by AstraZeneca. Theassignments follow a structure (goal of assignment, preparations, experiment and follow-up)inspired by the concept of NTA ? Naturvetenskap och Teknik för Alla (Science andTechnology for everyone).
Att tolka som barn : En kvalitativ studie om vuxnas mäns upplevelser av att under sin uppväxt ha fått tolka åt sina föräldrar
The purpose of this study was to within a Swedish context and from five persons of foreign descent stories study how they have been affected by interpreting for their parents during their childhood and how this has affected the relationships within the family. Studies conducted in an American context have shown that children interpreting for their parents in everyday situations are prone to undertake roles similar of a family leader. Previous studies also show an increased danger of depression among children who interpreted for their parents. The study was conducted by the use of semi-structured interviews with five male respondents with a varying ethnic background. Using Antonovsky´s theoretical formulation ?sense of coherence? we were able to determine that although our respondents during their childhood were subjected to a large amount of stressful elements they also maintained a high sense of well-being.
Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Säg det! : En undersökning om hur rektor kan synliggöra lärares undervisningsförmågor likväl som läraren kan synliggöra elevens lärande ? en parallellprocess
-------------------------- 4AbstractThis study is a qualitative case study in order to delineate how visible learning processes in the classroom. The study draws its theory from researcher John Hattie's findings about effective teaching. Data collection is taken from a class in grade 2 in a medium-sized Swedish municipality. The result demonstrates how the communication takes place in the classroom based on the teacher's strategies and planning in relation to pupils' interests and their own initiative. Is there a mutual feedback between teachers and students while teaching? From five perspectives, and the definition of what visible learning is all about, the results shows many good examples of excellent teaching.
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.
Inredningsförslag till Bolandgymnasiets matsal
My bachelor?s dissertation concerns the creation of a proposal for interior decoration of the Boland High School?s canteen. I have been in contact with personnel, students and the school principal through the duration of the project. In the end, substantive changes of lighting, interior decoration and movement were proposed for the canteen. In the proposal I have focused on accentuating the school?s profile, on creating smaller spatial configurations within the larger configuration of the room, lowering the noise level, creating a good movement flow, increase the number of seats and creating a pleasant environment in which to eat..
Commercialisation of inventions from a legal and business perspective
This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.
"GODNATTSAGAN - Vart tog den vägen?" : En undersökning av småbarnsföräldrars aktiviteter tillsammans med sina barn.
The overall purpose of this essay is to come to a deeper understanding about videos in the Youtube beauty community by using a mixture of qualitative and quantitative methods. By answering the main questions of the essay which are; What quantitatively measurable components are there in the videos that can be seen as contributing factors leading to the fact that some generate more views that others?; Is there a set mold for success containing certain aspects that a video must have to stand out?; What correlations can be found between the two categories of analysis and how do these potential correlations affect the popularity of the video? and What effects do specific components on the level of popularity of the video?, we?ve been able to distinguish differences as well as similarities on both qualitative and quantitative levels. We have also seen that using the two methods together have enabled us to reach more profound results. The main result that we have found on a quantitative level is that there are obvious correlations between a high level of popularity and a good visual quality.
Humant papillomvirus : Gymnasieelevers kunskaper om och attityder till HPV, HPV-vaccin, kondomanvändning och cellprovtagning
Purpose: To assess awareness and attitudes regarding HPV, HPV-vaccines, use of condom and participation in pap-smear screening among high-school students in Uppsala County. The intention was also to investigate if there were any differences between students at theoretical programmes and vocational programmes.Methods: 608 students from seven high-schools in Uppsala County answered a questionnaire covering demographics, awareness and attitudes regarding HPV, HPV-vaccine, use of condoms and pap-smear tests.Results: A majority of the students had never heard of HPV (86 %, n=521), HPV-vaccine (94 %, n=537) or the link between HPV and cervical cancer (88 %, n=563). Most respondents had a positive attitude towards HPV-vaccine (84 %, n=508), but the biggest obstacle was the high cost (37 %, n=227). The students believed that it was less likely that they would use a condom with a new partner if vaccinated (mean=78, SD=26, p<0.001), or if they or their partner used contraceptive pills (mean=62, SD=32, p<0.001) compared to how likely it was that they would use a condom in general with a new partner. The girls rated the probability that they would participate in a pap-smear screening as relatively low if vaccinated (mean=59 SD=27).
