Behovstyrd ventilation Ugglumsskolans gymnastikhall

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

Tre studenter med ADHD berättar om upplevelsen av att läsa i högre utbildning

Research shows that there is a lack of knowledge of adult students with ADHD. Most of all research focuses on children with ADHD in school. The purpose of this study was to gain a better understanding of how adult learners with ADHD experience academic studies related to cognitive difficulties, emotion, motivation, and their experience of SOC. The questions tried to determine how any cognitive difficulties and emotions are perceived, how students' motivation to study impacted and their experience of SOC based on studies in higher education. To answer the purpose and questions used qualitative interviews based on three students with ADHD using a hermeneutic method.

Cytologiska bedömningens påverkan på analysen av bronkoalveolärt lavage (BAL) samt förhållandet mellan andelen mastceller och proinflammatoriska cytokinmediatorer i BAL hos häst :

Inflammatory airway disease (IAD) is a respiratory disorder that most commonly affects young horses performing at a high level. The clinical signs are often mild but the disorder can cause a marked decrease in performance to a point where the horse has to be taken of training and competing. The aetiology underlying IAD is not yet fully understood. One current theory is that a type I-hypersensitivity reaction due to allergens in the environment is the cause in some horses. The most reliable diagnostic method is a bronchoalveolar lavage (BAL) since it reflects the inflammatory status in the most distal parts of the lungs, which are affected in IAD.

?Man försöker haka på något? - Om gymnasiebibliotekariers professionsroll i arbetet med elevers läsförståelse och deras roll i skolans pedagogiska verksamhet

This paper conducts a qualitative examination based on interviews with four high school librarians. The purpose is to illustrate their professional role in proportion to that of the teachers from working with students? reading comprehension and from their role, if any, in the school?s educational activity. The work is based on the following questions:- How does the high school librarian describe his or her work to increase the students' reading comprehension and contribute to their reading development?- How does the high school librarian describe his or her involvement in the schools? educational activity?- How can one understand the high school librarians' relation to the teachers with reference to the librarians? jurisdiction and the formal and actual legitimacy of the school library profession?The theoretical framework constitutes of the concept of jurisdiction and of formal and actual legitimacy.

Barns beteenden i naturen

AbstractThis study is based on qualitative interviews with five-year-old children from a nursery school and two teachers with great experience. The purpose with the interviews is to find out what knowledge these children have about the Right of Common and what the teachers think they need to find this knowledge.The children didn't know what the word Right of Common stands for but when they got more concrete alternatives they had good experiences. The two teachers had different opinions about what is the most important concerning the stays in the nature. Exercise meant a lot for one teacher. To have fun and to use all your senses were more important for the other one.

Mät och loggningsutrustning för spänningstransienter

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

Barnens säkerhet utifrån ett lärarperspektiv : En studie om rådande resursskillnader i en låg- respektive högstatusskola

That the Swedish society looks different depending on the location is a fact and that in turn means different schools with different conditions and resources depending on the localization. We have in this study interviewed four teachers in a high-status school and four teachers at a low-status school in a municipality south of Stockholm. The purpose of our study is to find out how teachers / educators perceive children's physical and psychological safety in their workplaces, and if there is a difference between the schools in resource allocation.In order to answer our purpose of the study, we chose to interview teachers about how the school looks for the kids in order of enough resources such as books for all, enough facilities and competent and even skilled teachers. To take into account and consider people´s backgrounds, experiences, and cultural frames of reference is a way to interact within a respectful world, and as a good approach to educating children from all parts of the world and with all the different mental and physical difficulties. The two schools in our study show lack of resources but of different kinds.

Alkoholvanor inom det gymnasiala fordonsprogrammet

The consumption of alcohol in Sweden has increased considerably within recent years. Among youths there has been a tendency towards drinking more frequently and increased volumes. Alcohol habits among students on the high schools auto mechanic line has been given a questionnaire to examine their experience of the immediate after effect of alcohol and how et effects their situation in school. It has been proven that participating students are drinking alcohol more frequently than the average among Swedish high school students and girls more often than boys. The general experiences of alcohol after effect are predominantly negative both physically and psychologically, but the students are not concerned of their alcohol habits having an effect on their school work..

Vogler och pergolesis stabat mater: En väg till historiskt informerad uppförandepraxis

The author is active as a musician in the field of historically informed performance practice (HIP) which emanated from the 20th century early music movement. Studying of historical sources has a central role, but the problem of how interpretation and selection of source material is affected by art and music ideals of our time, is commonly acknowledged. Georg Joseph Vogler shows in a series of articles in "Betrachtungen der Mannheimer Tonschule" (1778-1781) how Stabat Mater by Pergolesi could, and in his opininon, should be improved. The purpose of this thesis is to investigate how this source can be used from the standpoint of a performing musician: How can I use Vogler?s methods in my playing?The introduction problematizes Vogler?s action in relation to his time, and to ours.

Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.
