Examensarbetets syfte var att konstruera en reglermekanism till en HCCI-motor. HCCImotornär en motkolvsmotor med variabel kompression. En motkolvsmotor är i teorinbättre än en vanlig motor på grund av att det går att utvinna arbetet från förbränningen itvå riktningar, värmen verkar på två ytor istället för en. Huvudproblemet med dettaexamensarbete har varit att uppskatta de krafter som verkar i systemet, samt att utvecklaett enkelt sätt att reglera fasen mellan vevaxlarna. Beräkningen av de krafter somuppkommer i reglermekanismen är komplicerad på grund av att mekanismen rör sigunder körning.

Traditionellt utvärderas effekter av kognitiv träning med objektiva prestationsmått. Syftet med uppsatsen var att undersöka självskattad exekutiv funktion som ett alternativt mått för att utvärdera effekter av kognitiv träning. Som utfallsmått valdes The behavior rating inventory of executive functioning - self report (BRIEF-SR). Vidare användes blandad design med för- och eftermätning samt tre oberoende grupper. Gymnasieelever (n = 63) delades in i; aktiv träningsgrupp, aktiv placebogrupp och passiv kontrollgrupp.

The use of tobacco is one of the largest health risks for human. Tobacco-users have an incrased risk of deterioration in their oral health. Individuals starts to use tobacco when they are young, often at the same time as they are going in an athletic sport club. It also seems that children are starting with tobacco habits when they are active in athletic sport clubs. The aim of this study was to examine and compare tobacco-habits of young men in and between three different athletic sport clubs.

AbstractSwedish tuition for immigrants (SFI) is a public adult education program in Sweden that was created in order to provide the immigrants with basic skills in Swedish. People with different backgrounds speaking different languages learn together how they should communicate in Swedish, both orally and in writing. For those who teach SFI it is important to know which factors have positive effects on the Swedish language acquisition. One of the questions to be asked is if the learning materials´ genre has any effect on the SFI students´ proficiency, in particular, oral proficiency. Scientists as von Franz, Vygotskiy and Bettelheim argued that fairy tales, as a genre consciously or subconsciously recognizable by all the people, present texts that are easy to acqiure.

 Through teaching, pupils are given the opportunity based on their personal experiences and current events to express and consider their views in relation to others who hold different views. As a result, pupils should be encouraged to get involved and participate in an open exchange of views on societal issues (Skolverket, 2011d, s. 189). To assess pupils orally in the subject of civics in primary education is an unexplored field, which makes this field relevant to explore. There are numerous researchers? who with the help of deliberative methods, formative feedback, formative assessment and studies regarding classroom climates whom all speak positive about using discussion/dialogue in education to upraise and develop learning among pupils.

The aim of this study was to investigate the effects of an infusion of hypertonic saline solution (HSS) in combination with an oral waterload on cows suffering from rightsided displacement of the abomasum (RDA). Six dairy cows were treated with 7,2% HSS in a dosis of 5 ml per kg bodyweight. They also received an oral waterload of approximately 15 liters. To monitor changes in fluid-, acid-base- and electrolyte-balance, bloodsamples were collected during the next 24 hours. During this period, the cows also underwent surgery to empty and correct the position of the abomasum.

The purpose of this study is to examine the teachings of rhetoric?s in schools, more specifically within the Swedish subject; furthermore it examines how Swedish teachers work with rhetoric in the Swedish subject on a practical basis. The study also highlights teachers' approaches to the curriculum for high school. The method I have used to conduct this study, have been to use interviews and inductive ethnography. The teachers whom have been interviewed in my study have similar understandings of what oral presentations actually are, but their idea of what the term rhetoric stands for however differs. Teachers have received similar training in rhetoric; however, they have different experiences within it.

Introduktion: Ätstörningar som Anorexia Nervosa (AN) och Bulimia Nervosa (BN) innebär ett folkhälsoproblem och orsakar oral ohälsa. Vid ätstörningar har individen en störd kroppsupplevelse och försöker kontrollera sin vikt och kroppsform. Under de senaste decennierna har det skett en omfattande ökning i förekomsten av ätstörningar. Syfte: Att beskriva oral hälsa vid ätstörningar.   Frågeställningar: Hur påverkas den orala hälsan av sjukdomen AN? Hur påverkas den orala hälsan av sjukdomen BN? Metod: Designen är en litteraturstudie i området oral hälsa och ätstörningar.

The aim of this study is to examine the knowledge and experience of the bad breath among high school students in Kristianstad. A further objective was to measure the amount of VSC (Volatile Sulfur Compounds) among those who perceive themselves to have a bad breath. A questionnaire with 21 closed questions was distributed to 120 high school students from Kristianstad municipality who were between the ages of 17-20. The results of this study revealed that most of the students had good knowledge of halitosis. The majority of all participants thought it was important to smell fresh in the mouth and also experienced most of their breath as very good or good.

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

Inledning: Oral cancer är ett allvarligt tillstånd med hög dödlighet, särskilt vid sen diagnostisering. Brasilien är ett av de länder i världen som har högst prevalens och dödlighet i oral cancer och det är den femte vanligaste cancerformen I landet. Ett hjälpmedel för tidig diagnostisering är önskvärd. Syfte: Att utvärdera skillnaden i diagnostisk tillförlitlighet mellan konventionell oral undersökning och användning av multispektralt ljus (Identafi®) som en metod för tidig upptäckt av potentiellt maligna och maligna lesioner i munslemhinnan i en brasiliansk befolkning. Material och metod: Screening av en befolkning med förhöjd risk för att utveckla oral cancer i Goiânia, Goiás, Brasilien, för att upptäcka potentiellt maligna (PML) eller maligna lesioner (ML). Patienter med misstänkta PML eller ML upptäckta under screeningen undersöktes med multispektralt ljus (Identafi®). Tre oberoende observatörer genomförde bedömning med Identafi® och slutgiltig beslut avseende PML/ML togs i konsensus.
