The key elements of sourdough fermentation are the presence of active lactic acid bacteria (LAB) and yeast. Sourdough fermentation originates from the ancient Egypt. One theory concerning its onset states that a portion of bread dough was set aside to be baked at a later date and started to ferment spontaneously.Sourdough may contain a wide variety of microorganisms, mainly dominated by LAB and yeast. There are over 50 species of LAB that has been identified in various sourdoughs and more than 20 species of yeast. Sourdough fermentation has been shown to have various impacts on baked cereal good, most of which are attributed to LAB.This study addresses some effects of LAB from fermented milk products in sourdough and sourdough bread.

The aim of this essay is to examine why and how three teachers who work in elementary classes choose to use ability grouping during math lessons and what they think of ability grouping as a method to individualize the activities according to the pupil?s needs.I chose one main question for this study that is the following:What is the teacher?s point of view and experience of ability grouping in teaching mathematics?And three sub-questions:What are the motives behind the choice of ability grouping?What are the advantages of ability grouping?What are the disadvantages of ability grouping?In order to be able to answer my questions, I used the qualitative method. I interviewed three teachers who work in the elementary classes (First to fifth grade) to find out what they think about ability grouping and how it is experienced in mathematic teaching.The result shows that the common thing between these three teachers is that they don?t use ability grouping as the only teaching method. They all agree that the whole class teaching has many benefits for the pupils.

The Swedish preschool combines both education and care from a holistic point of view. This makes it even harder for both parents and the educators to make an objective evaluation on their own preschool. In Sweden we are proud to have one of the world?s best preschools. It is regulated by the government and is obligated to undertake critical evaluation from the state and the parents that are the consumers of these services.

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group.

There are many theories about the concept male and female and the meaning of these words.

This survey examines how a regional archive, Värmland Archives, interprets and works from the departure point of national cultural accessibility goal ?Everyone should have the opportunity to participate in cultural life?. And it is also a comporative study of discourse regarding accessibility between Värmland Archives and some other actors in the archival cultural system. Critical discourse analysis, according to Norman Fairclough, is used as a theory method. A discourse analysis is made on empirical data based on document study and qualitative research interviews. My conclusion is that if the term Accessibility is seen as a focal point the accessibility discourse in the documents of Värmland Archives and of the other actors studied can not be clearly discerned. Värmland Archives´s interpretation of terms regarding accessibility analyzed in the survey, varies among the staff regarding how the archives and its services should be accessible, and what accessibility means in the context of the archives.

Virtualisering och övervakning är två snabbt växande områden inom IT-branschen. Denna rapport behandlar övervakningen av databas-servrar med hjälp av två olika verktyg, op5 monitor samt VMware vCenter.Det svenska företaget op5 AB har utvecklat op5 monitor och detta verktyg används idag av flera stora företag för att övervaka deras nätverkselement, Data Ductus är ett av dem. Ductus ligger i framkant när det kommer till systemövervakning men är i behov att utöka sin övervakning på databas-servrar. Uppdraget antogs därför av oss att hitta en lösning som ska kunna implementeras i deras produktionsmiljö.Beskrivningar presenteras av de teoretiska delar som ingår i övervakning och virtualisering med VMware ESXi. En lösning för att övervaka Microsofts databasserver i op5 tas fram och testas, lösningen görs så generell som möjligt för att den lätt ska kunna tas i bruk.Även en jämförelse mellan fysisk och virtuell övervakning granskas och perl-programmet check mssql health används som mall för att skapa checkar av intressanta mätvärden att övervaka hos en databas-server.Felkällor och förbättringar samt framtida arbete diskuteras och slutsatsen dras att op5 är det överlägsna övervakningsverktyget på grund av dess flexibilitet..

The agriculture throughout the world is becoming increasingly deregulated and this has affected the prices of raw materials to fluctuate at a higher degree than earlier. This in turn has made it interesting and in some cases even necessary for the trader as well as the producer to gain knowledge about the trade instruments available to ensure a good enough price for their produced goods. This study encompasses a number of ways to trade grain and oil plants in order to clarify what differences there are in the several contracts that exist in the present situation, economical as well as practical. The various trade instruments available to the producers on the Swedish market are described in the theoretical part of this study. The study also contains a simple arithmetic example, based on historical prices collected from grain traders and trading floors, in order to point out the differences in the economical outcomes depending on the business strategy used to sell the produced goods. The study shows the importance, as a producer, of being able to use and take advantage of the different trading instruments at hand to monitor and exploit the shifts in the market. From an economical point of view it is not enough to just excel at farming but knowledge about the market functions and the trade instruments at hand is also required to be able to secure a good enough price for your goods.

Leber´s hereditary optic neuropathy (LHON), a disease affecting vision, is caused by several point mutations in mitochondrial DNA. Mutations leading to a defect NADH ubiquinone oxidoreductase protein will affect the respiratory chain and cause a disturbed ATP production. It is still unknown why this defect leads to the degeneration of retinal ganglion cells and cells in the opticus nerve as well as demyelination of axons in these areas. Analysis of mitochondrial DNA is an important tool in the diagnosis of the disease. At the present time analysis is based on cleavage by restriction enzymes, which only detects two of the most frequent mutations: m.3460G>A and m.11778G>A.

The purpose of the essay is to discuss from the theory about the established and the Outsiders if the Culture Centre Blå Stället can serve as a meeting point between the majority of the people and the minority of the people in Gothenburg. The idea of Blå Stället is that it shall work as a house available for everyone and as a cultural meeting point between people in and outside Angered. I argue if Blå Stället really is a place where people from Gothenburg as a whole go or if there are some hindrances for their visions. My study is comprised of interviews with three of the staff at Blå Stället. With the theory about the established and the outsiders I want to show that the division in the city between ?them? and ?us? has to do with differences of power.

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.

The current state of our web is one where users can create and distribute information freely and without constraining limitations of knowledge. It?s as easy as making a Facebook status update or sending out a Tweet to make contributions to the web and we?re all doing it. Web-Giants like Facebook and Google deinate the web because they have such massive user amounts and therfore they control the information their users see. This is a problem because we?re hidden from the entire information amount that is the web in the 21st century.

This study describes how verbal abuse is used in schools and how it affects students. As a  result of the study is a questionnaire which was distributed to 153 students at two schools in a small town in southern Sweden. Students who participated in the study were in grades 3-6 and were between 9 and 13 years old. I asked students 13 questions, which dealt with verbal abuse, some of them were check questions and some were issues that required a longer response.The results of the survey show that 108 students of 153 have ever felt verbally abused at school, slightly more girls than boys. Usually they say they have been verbally abused by their own sex and then with words like boys are more frequently offended by words of a sexual nature, whereas girls more often are offended by words that violate their appearance.The students who feel aggrieved are shown to be those students who violate others.
