Utvärdering av viabilitet hos selekterad hingstsperma med hjälp av fluorometri :

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Nyckeltal för älg och fodertillgång på tall Pinus sylvestris och rönn Sorbus aucuparia

It has been shown that moose can affect plant community composition and structure. Selective browsing with other damages of large herbivores on tree species with different tolerance to disturbance could reshape the tree layer in both managed and natural forests. Rowan Sorbus aucuparia is widely distributed throughout Sweden and Europe. Research has shown that browsing by moose may prevent rowan from reaching browsing safe heights. The goal has been formulated that, where rowan is indigenous, it should have a good competition status and be able to reach tree level.

Fiberföstärkning av Limträbalkar

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

Ekot av normerna : En diskursanalytisk studie av hur kön konstrueras i Dagens Ekos nyhetssändningar

Sweden?s most trusted news distributor, Sveriges Radio (Swedish Public Service radio broadcaster), has high ambitions with the journalism it broadcasts ? especially when it comes to gender equality and diversity. This thesis examines how gender is constructed in Dagens Eko (Today?s Echo) to find if and how power structures are expressed language-wise. Queer theory is used to look at how gender is constructed and how one can look at, and question, gender and gender hierarchies.

Uppfostrad av samhället : ? En studie av 6 grundskoleläroplaner från 1900-talet

Democracy has been a part of the Swedish society for a long period of time and it is also a part of the Swedish elementary school curriculum, in which you can find a number of statements that expresses that the Swedish elementary school should socialize the children into becoming role model citizens. This also conjures with the available research that describes schools in general as socializing. This led me to a question that hasn?t been answered: How much of the curriculums reasons for socialization the pupils are based on democratic values and how much of it can be dated back to events prior to the curriculum?The methodological approach is an analysis of ideologies as described by Sven-Eric Liedman and Ingemar Nilsson in Ideologi och ideologianalys. The text is focusing on the fact that a text has two layers; one is the manifest which is roughly the same as explicit or present in the text.

Förbättring av U-värde i träkonstruktion för fönster med Aerogel

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?

The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.

Valmöjligheter i samband med prefabricerade badrum

This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.The recent problems with damage caused by damp in bathrooms. Have resultade in regulations.

Trädgårdar på tak- och gårdsbjälklag :

The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens. Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions. The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.

Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat

Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

Visualisering av basalcellscancer med Tissue Viability Imaging - ett icke-invasivt diagnostiskt alternativ

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.
