Kalvutdragaren - en hjälpande hand? :
The calf extrator?s function has been studied, through measuring traction and how
this varies in different situations, in comparison with corresponding manual
traction situations. This was done against the background that excessive force at
assisted calvings at dystocia can mean life threatening damages on the calf such as
grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf
extractor has earlier been measured to pull with greater force than the established
maximum force of ?two strong men?.
En författarcociteringsanalys av forskningsfältet socialpsykologi
The aim of this thesis is to use the bibliometric method author cocitation analysis (ACA) and investigate the cognitive structure in a research field, which is called the intellectual base. The research field in this investigation is social psychology. The main question is: what is the nature of the cognitive structure, which contains of the intellectual base. This question is divided in two sub questions: ? Which are the most prominent authors in the research field? ? Which sub areas, based on groups of the most cocited authors in the research field, can be identified?An investigation with ACA is used to describe the general experience of consensus of later authors in a research field.
Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
Analys och kontroll av hållfasthet på grenställsarm
The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
"Statistiskt sett har ju NE också fel" : en kvalitativ studie rörande gymnasiebibliotekariers uppfattningar och undervisning kring Wikipedia
The main purpose of this bachelor?s thesis is to examine how Swedish upper secondary school librarians and related staff relate to the online encyclopaedia Wikipedia. The research is placed in the all-embracing context of information literacy and source criticism on the Internet. The study was carried out in the form of qualitative interviews and based on two theoretical bases: firstly, the concept of cognitive authority stipulated by Patrick Wilson, and secondly the idea that Wikipedia has a draw towards late modern epistemological assumptions. The latter theory was also associated with the perceptions of knowledge among the library staff interviewed.
Svenska varumärkens kulturella värden
Background: Today many companies are competing to get space in our minds. Companies spend a tremendous amount of money on building strong brands. It is not just about making us aware of their logo, today it?s more about giving the brand a ?soul? and to load it with different values. Due to today?s globalization there is also interesting to look at it from a cultural perspective.
Informationskompetens - färdighet eller insikt? En jämförelse mellan två modeller över begreppet informationskompetens
This Master's thesis in library and information science aims to shed light on the concept of information literacy in higher education, particularly as manifested in two dissertations on the subject. Two models of information literacy are compared: Christina Doyle's list of ten attributes for students to master and Christine Bruce's seven conceptions of information literacy. The cognitive-behaviourist tradition in Doyle's study and the alternative, phenomenographic approach in Bruce's research are compared and commented. The taxonomies and internal relationship between separate components in the two models are investigated, as well as the ways the models relate to each other. The respective views of knowledge and learning are described.
Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys
People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).
Är cannabis den nya folkölen? : Unga cannabisanvändares tal om cannabis
The aim of this study was to examine young adult cannabis users? attitudes towards cannabis and their perception of the normalization of cannabis. The purpose was also to explore how their views of cannabis correspond with norms regarding cannabis. This study is based on interviews with five young adult cannabis users. The theoretical framework is based on Parker?s normalization thesis, Goffman?s notion of stigma, Becker?s definition of outsiders and the definition of social identity developed by Stone.
En dag på arbetet: sjuksköterskeprofessionens informationspraktik
The aim of this thesis is to create an understanding of nurses' information practices. To be able to search, find, use and critically evaluate information is important, not just during studies, but also in professional life. This study is intended to deepen our understanding of nurses ' information literacy in a workplace context.The main questions are: What information do nurses need on a daily basis and how do they experience information activities? What factors determine the sources they use? Do information practices vary in the workplace? Do nurses? professional experiences impact on their information practices? Nine nurses were interviewed using semi-structured interviews. The interviews have been analysed through a hermeneutic approach.
Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3
The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.
Lyssna! Sex vuxna individers upplevelser av att berätta om de sexuella övergrepp de har utsatts för i sin barndom.
The aim of this qualitative study was to examine six individuals' experiences to talk about the sexual abuse that occurred in their childhood. We interviewed five women and one man, using a phenomenological approach during the work process. The theories emerged as we analyzed our results and appeared to be communication, cognitive theory, validation, trauma theory and taboo. The results showed that the respondents, whom disclosed the abuse as children, were most likely to get a negative response from both formal and informal support systems. While as adults they were confirmed to a greater extent and therefore achieved a better physical and mental wellbeing.
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Läsförmågan hos barn med mild och måttlig hörselnedsättning : Hur ser sambandet med underliggande kognitiva förmågor ut?
While reading in deaf children has been the object of a number of studies, the reading abilitiesof children with mild and moderate hearing impairment and their relation to cognitiveprocessing have not received very much attention. Predictive factors of reading ability inhearing children are well known, with phonological and working memory abilities beingnecessary prerequisites for reading development. Existing studies suggest, however, thatcertain hearing-impaired children achieve a reading level comparable to that of hearingchildren in spite of impaired phonological abilities. In the present study, reading abilities anda range of cognitive processing abilities were measured in a group of hearing-impairedchildren and compared with hearing controls in equivalent school grades. Comparisons weremade at group and school-grade level, and the cognitive profile of hearing-impaired childrenat level with controls (those being within one standard deviation) was discussed.
Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare
Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.
