Alkali-kiselsyrareaktionen (AKR) är en kemisk reaktion som medför att spänningar uppstår i betongen då den bildade silikatgelen expanderar. Reaktionen kräver tillräcklig hög alkalihalt, reaktiv ballast samt vatten. På grund av de AKR-inducerade spänningarna är det av intresse att få kunskap i hur reaktionen påverkar betongens böjmomentkapacitet, förankring samt skjuvnings- och genomstansningskapacitet. För att besvara frågeställningen har därför en omfattande litteraturinventering tillsammans med tre kompletterande intervjuer utförts. Resultat som har erhållits, påvisar att två huvudsakliga effekter fås av AKR.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

The main purpose of this bachelor thesis is to examine the existence of criteria and to what extent high school students use these criteria when they are collecting information for a school assignment. I also compare students attending different high school programmes with each other and compare students on different levels of education.I have done a quantitative study with 284 students in which the students have filled out questionnaires.The result shows that the most common way to evaluate information is to compare sources with each other. Students also look at how the information is written, and they want the information to be detailed and easily available. More seldom used criteria include consideration of the authority of the writer, determination of how up to date the information is, and gauging the perspective of the information.The result also shows that students attending a high school programme that prepares them for higher education are better at evaluating information than students attending a high school programme of vocational preparation. Students at a higher level of education are also better at evaluating information than students at a lower level of education. .

Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning. Forskning har därför riktats mot att undersöka hur hämmad effekt kan undvikas. Syftet med litteraturöversikten var att genom att granska vetenskaplig litteratur i området beskriva faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighetoch styrketräningsprogram. En beskrivande litteraturstudie gjordes på ämnet. En litteratursökning genomfördes mellan 6-24/9, 2014 i databaserna Scopus, Proquest, Pubmed, Cinahl, AMED, Web Of Sciense.

This study aims to examine attitudes and conceptions of staff who work with mentally disabled persons, concerning normalization and gender. Six qualitative interviews with such professionals were performed and subsequently analyzed. Since the method of this study is qualitative, no claim of generalizability is made. The interview material has been categorized into themes by means of coding. The result of the study is presented according to those themes.

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

Background: The competition is getting harder between the universities. To reach the high school students and discover which means of contact they prefer and how they perceive student recruitment are important issues in order to succeed in marketing strategies.Purpose: The purpose with our report is to investigate, analyze and compare the student recruitment in three universities and investigate how the high school students want to be contacted. Then we compare to see if they think alike.Method: We have done a qualitative study and chosen to use focus group interviews for the high school students and interviews for the universities to collect our empirical data. We have compared the empirical data and analyzed it with communication processes and marketing communication as theoretical grounds.Result: All of the universities work approximately the same way with their student recruitment. They put a large effort in the Internet and social networks as well as the personal contact.

Banks and their products are traditionally characterized as high involvement, informational purchases and as such there is a need to shape the market communication to be logical and catering to the need for information that customers are bound to have. With the advent of social media and web 2.0 a company can no longer opt out of the online discourse regarding their company. As social medias are characterized by being an active media, tailored to personal exchanges and opinions, the match with the high involvement approach that banks usually have to employ is not always ideal. We have examined what happens when banks use different degrees of personal message content and sender profiles on Twitter. Our findings suggest that while some strategies generate higher WOM intentions, others may provide a greater level of sender credibility..

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical Nutrition3AbstractTitle: How does isoflavones in combination with soy protein impact cholesterol levels in hypercholesterolemic postmenopausal women relative to milk protein?Author: Emma Edberg och Emma NilssonSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician stydy programme,180/240 hpType of paper: Examination paper, 15 hpDate: 2014-05-26Background: Hypercholesterolemia is a major risk factor for cardiovascular disease and the number one cause of death among women in Western countries. Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

There is a growing awareness that multinational companies have opportunities to influence political conditions. Ethical activities made by multinational companies and ?Corporate Social Responsibility? (CSR) can therefore function as a positive input in society. The primary purpose of this master thesis is to investigate CSR´s contribution to strengthen human rights, and thereby to democratization. The research questions are listed below:1.

This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.

Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.

In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the grain prizes are at a historic high level. In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.
