?Det finns någon slags Open Access där ute?. En idé- och ideologianalys av bibliotekariers förhållningssätt till Open Access vid sex forskningsinstitut.
The Open Access (OA) movement came to be as a reaction against the enclosure of information resources, facilitated by new distribution technologies. The purpose of the OA movement is to make research results freely available. The aim of this master´s thesis is to increase the understanding of how libraries outside of the academic sphere and within research institutes relates to OA. As a theoretical framework I created two different ideologies, the OA ideology and the nonsharing ideology. I also conducted six interviews with librarians.
Villa Berg : gestaltningsförslag inspirerat av funktionalismen
The functionalism started in southern Europe after world war one and got its breakthrough
in Sweden with the Stockholm Exhibition in 1930. Poverty caused many people living in
overcrowded conditions which the functionalists wanted to change by using less expensive
materials and giving healthier living conditions to the people. The industrialization brought
new materials and working methods which made this possible. The Swedish functional style
is recognised by its light plaster facing and nearly horizontal roofs.
Also the garden design of that time was influenced by the functionalistic ideas. The garden
was now introduced as a pleasure garden for not only the rich but for everyone.
Utredning av laserskärningens materialpåverkan inför drag- och slagprovning : Teknisk Fysik med Materialvetenskap
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Effekten av hormonsubstitution hos äldre män med åldersrelaterad testosteronbrist: en litteraturgranskning
Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).
Personlig träning på egen hand
AbstractThe purpose of this essay was to determent if the authors? idea to replace a personal trainer with a training program, which is provided by software, is viable and if there is a market for such a product. The method that was used, included eight people who enrolled in a training program which were designed by the authors in Microsoft excel. The programs were based on principals of periodization, and included the phases: anatomic adaptation, hypertrophy, maximum strength and muscle definition. The training program was personal and based on individual goal setting.
Logopeders bedömning av funktionell kommunikation hos personer med afasi : En enkätstudie riktad till logopeder i Sverige
There are several different methods of assessment of functional communication in individuals with aphasia. However, these are not very established in Sweden. A number of assessment methods are not translated and adapted to Swedish. The views about what functional communication means are scattered. The purpose of this study was to, with the help of a questionnaire survey, identify how Swedish speech and language therapists assess functional communication, to what extent and what they want that an assessment method should contain to be clinically useful.The study involved 54 clinically active speech and language therapists in the area of aphasia.
Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik
Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.
Bland Bokbaciller och Vingklippta Änglar ? En kvalitativ studie kring bestånd och beståndsarbete på fem sjukhusbiblioteks barn- och ungdomsavdelningar
The main purpose of this thesis was to examine the collection management at five different hospital libraries´ children and youth?s section to discern different roles of the collections. We made qualitative interviews with five hospital librarians. The purpose was also to see how the collection development affected the different roles of the collections. We used two theories.
The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials
Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.
En bra plats för lek : kreativ och tillgänglig lekplats i Hedemora
For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and
for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play.
A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose
irregular forms and structures can become interesting elements to explore. Vegetation
also gives sence-experiences of various kinds, materials like twigs and leafs to play with
and a place to play house.

Miljöbedömning av olika behandlingsmetoder för organiskt hushållsavfall, slakteriavfall och flytgödsel
Organic material used for biogas production can also undergo other treatments. The
emissions and impact from the different treatments are evaluated in this
environmental assessment, with a focus on energy and climate. The materials
included in the study are organic household waste, slaughterhouse waste and liquid
manure. Other than biogas production, the possible treatments for organic household
waste and slaughterhouse waste are incineration and composting, and for liquid
manure storing and spreading. The analysis is based on data and information from
current and relevant literature, and relates to the conditions in the Swedish energy
system.
