Dokumentation av en experimentell biogasanläggning
This thesis is focused on identifying and documenting all electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief technical description and information of the systems around the reactors. Furthermore there will be a brief description of LabVIEW - which is a graphical programming language- and which devices / elements are programmed. For further notification, I am not responsible for the programming of the devices in LabVIEW which I have only used as a Tool in my work. The plant for production of biogas consists of four reactors of which the third reactor (Lakbädden) is connected to another reactor (UASB) where they cooperate with each other. The reactors are used for producing biogas in the form of methane gas.The reactors I and II are connected to, various electrical devices as, flow meters, temperature sensors, frequency converter and more.
Att plantera LÖK:ar för att undkomma osäkerheten: en studie av myndighetssamverkan kring introduktionen av nyanlända flyktingar och andra invandrare
The purpose of this project was to find an understanding for why public agents working with introduction of immigrants have decided to co-operate and co-ordinate their efforts. Another purpose was to gain insights in what characterizes this co-operation.Seven interviews were made with practitioners working with these questions on national-, regional- and local levels. The material gathered in this process was then analysed using governance theory and more specific the parts dealing with Joined- up government and Whole- of Government. Two analytic Tools were used in the analysis: wicked problems and network.The first of these, wicked problems, was made operational by the use of insecurities. Analysing the interviews along these lines proved very useful in explaining why public agents have decided to try to work together.
Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester
The Yara N-Tester is a handheld chlorophyll meter which can be used in several different
crops as an aid to determine if there is a need of complementary fertilization with nitrogen
(N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha.
The possibility to assess the need of N depends on the strong relation that exists between
chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series
?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was
carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters
ability to estimate the need of N in winter wheat, will be presented for the years
2008-2011.
Läxan som ett medierande redskap : En kvalitativ studie om samarbetet mellan skola och hem ur ett lärarperspektiv
Studiens syfte var att ta del och göra en analys av lärares erfarenheter av samarbete med vårdnadshavare avgränsat till stöd i elevernas läxor. Vi ville identifiera betydande faktorer för ett samarbete mellan skola och hem och ta del av lärares eventuella visioner om ett utvecklat samarbete. Studien bygger på kvalitativa intervjuer med sex verksamma lärare i årskurs 1-3. Vi har utgått från begrepp ur ett sociokulturellt och socialekologiskt perspektiv i vår tolkning av det empiriska materialet. Resultatet visar att lärarna anser att det är viktigt med ett samarbete mellan skola och hem kring läxorna.
Aroma Theory: Scenting the Attitude
The thesis examines the relationship between consumer attitudes and a scented shopping environment. A relationship and phenomena concerning scent marketing, which could be seen as one of the more provocative forms of marketing since the human sense of smell, is connected to the limbic system where motivation and attitudes are created. The use of scent marketing has, so far, been proven effective in sales increasing whereas it is one of the less explored forms of marketing.The purpose of the thesis is to answer the following question: Is it possible to find differences in consumer attitudes in a scented buying environment compared to a nonscented buying environment, and thereby create new basis for segmentation?The thesis is based on a quantitative study where data has been gathered in a scent manipulated buying environment through structured interviews with consumers. The thesis applies a deductive approach to the main theories in the area of interest.The findings suggest new theory discussing that it is difficult to use consumer attitudes, towards a scented store environment, as a foundation for market segmentation.
Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica
Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.
Förlorad i övergången från aritmetik till algebra : Hur gymnasieelever översätter aritmetik till algebra
The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

Europa - en plats eller en idé? : En diskursanalys av den europeiska identitetens konstruktion
Today Europe is faced with an identity crisis concerning its borders. Turkey stands at the threshold for an EU-membership while the EU-Commission is trying to formulate what constitutes a European identity. This identity seeking process will determine the future not only for Turkey, but also for immigrants now living in Europe.In this thesis a discourse analysis, underpinned by socialconstructionist theory, is conducted to explore how the European identity has been constructed throughout history up until today. A starting point is that identity always is defined through a dialectical relationship to "otherness". Therefore the analysis is focused not only on what a European identity consists of but also what and who it excludes.
Empowerment: ett flytande begrepp?
The purpose of this study was to analyse the concept of empowerment and its meaning in the political document "En Förnyad Folkhälsopolitik" from the present Swedish government, containing guidelines and politics in the area of public health. The underlying question was if it could be considered as representative for some kind of general "empowerment approach" since the concept is central to the very definition of social work by the International Federation of Social Workers IFSW and International Association of Schools of Social Work (IASSW).By comparing its definition and consequences in the document with a historical review of different contexts of empowerment the conclusion was made that such a common approach doesn´t exist at all. The meaning of empowerment in the central document showed some similarities with the "northamerican" version of the concept represented by the social scientist Charles Murray, which is just one of the political meanings of empowerment. Alternative ways of understanding the concept was also presented such as being a Tool of a constant conflict between central political principles or as a fashionable but not important word. Another alternative was to consider it a means of power through witch different political discourses tries to dominate the world..
En laptop till varje elev : en studie om gymnasieskolans satsning på datorer i undervisningen
The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.
Från Novis till Mästare : En berättelse om socialarbetares yrkeskunnande
To the world you may be one person, but to one person you may be the worldThese words sum up my account of social worker expertise. How does one become skillful?a master?in the profession? I answer this question by exploring how social worker proficiency can be developed and grow with the help and support of supervisors, clients and colleagues. Development through professional supervision and in the encounter with clients is an essential part of the work. I also discuss what it means to be new in the field (a novice) in relation to being experienced (a master).
?Vems barn vill du att jag väljer bort?? En kvalitativ studie i en kommun i Västra Götaland om fem skolkuratorers upplevelse av stress i arbetet
The purpose of this study was to examine how school counselors in a specific municipalityviewed their work situation, if they experienced stress and how they would handle that stress.Five school counselors out of eight in the specific municipality participated in qualitativeinterviews where they could describe their feelings and thoughts. Their experiences wasexamined and analyzed with the theories of coping and empowerment. The results showedthat there were unhealthy levels of stress in the profession amongst the five counselors. It alsoshowed that the uttermost reason for the experienced unhealthy stress was the feeling of notbeing able to give as much time and help to the pupils as they want and need. The reason forthis was that an increasing number of pupils were, and are, experiencing unhappiness and arein need of seeing the school counselor.
Spelet om infrastrukturen - En diskursanalys av riksdagsledamöters föreställningar av offentlig privat samverkan
The purpose of this article is to describe the discourse in which public-private partnership (PPP) resides, within the Swedish parliament, in the field of infrastructure. I have chosen to look at the latest three years deliberation where PPP appears in parliament bills.This case study is based upon discourse as a qualitative method. Five indicator signs which is history, comparison, geographic location, vision of growth potential and solution controls the context of PPPThe result of the analysis was that a clear discourse was unravelled. A first rather surprising conclusion shows that it is possible to disconnect the discourse from PPP. PPP is not important by itself, the result shows that it only play the part of possible solution to the problems related to the discourse and does not have any value in its own.This result lead the conclusion that PPP is no more than a Tool for politicians to get as much out of their infrastructural aims as possible, as rational vote-maximizing actors.
Stress: En gransking av studenters stressnivå - Praktik och icke praktik
Practical and theoretical learning are methods that are used in schools as a
way to prepare students for the working life. Within the practical learning
knowledge is not only acquired to learn in practice, but the students must also
be able to apply their theoretical knowledge to what he/she does. Against this
background, the aim of the study was to investigate the importance of practical
learning for students in college / university level and how they are
experiencing the stress that may arise out of the loss of practical learning
during their education, as well as their vision for working life after
completing their education.
The population of the study consisted of N = 36, which 18 of these had used
both practical and theoretical learning and the remainder had only used
theoretical learning. The method was a questionnaire survey with a high
proportion of fixed alternative answers according to likert scales.
