When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

The aim of this thesis is to practice the theoretical methods that are concerned during the product development process of two new products. The theoretical concepts that embody the two products are created out of a product specification which is given by a commissioner with a private interest. The primary tasks of the design of the concepts are aimed on the products shape, which is to be created as a flexible structure by using silicon rubber as material.The storage box is a further development of the already known food storage box, or lunch box, which is common used in consumer kitchens. The main idea is to design a flexible product by using silicone rubber. It will able the storage box to be compressed when it is not used, be storage friendly and not consume more space than necessary in a storage compartment.

Bakgrund: Osteoporos har under de senaste decennierna utvecklats till en av de stora folksjukdomarna. I Sverige drabbas cirka 70 000 människor av osteoporosrelaterade frakturer varje år och av dessa är det främst kvinnor som drabbas. Risken för att en svensk kvinna någon gång under sin livstid skall drabbas av en osteoporosrelaterad fraktur är 50 %. Hur snabbt en kvinna förlorar benmassan samt hur stor benmassa hon har från början är avgörande för om hon kommer att drabbas av osteoporos och därför är prevention i ett tidigt skede viktigt. Syfte: Syftet med litteraturstudien var att belysa preventiva åtgärder för premenopausala kvinnor som kan förebygga primär osteoporos.

Södra Skog chose in 2011 to convert the saw mill in Traryd to a gradually refined sawmill of hardwood. In 2009, they had also acquired the hardwood sawmill in Djursdala. This was strategically important for Södra's business since the demand for hardwood products has increased. The standing volume of deciduous trees in Sweden is today approximately 524 million m3sk and it has increased rapidly in recent years. However, the deciduous forests are to a large extent located in areas that are set aside for nature conservation and is thus not available to the industry.The goal of this work is to create a simple and reliable method for mapping of deciduous wood volumes in areas where Södra Skog is operating (Götaland excluding Gotland).The material that is used is raster databases with estimated forest attributes (kNN-Sweden), data from National Forest Inventory (NFI) and forest management plans.

Botulism is a serious disease with high mortality that can affect horses. Due to this about 20-30 percent of the horses in Sweden are vaccinated against botulism. The purpose of this study was to see how common botulism is in the Swedish horse population and to se if a connection between feeding with haylage and botulism could be seen. In addition to this, the study aimed to find how common vaccination against botulism is among Swedish horses and on what grounds the diagnosis botulism is made. Medical records of horses being diagnosed with botulism at all the major large animal hospitals in Sweden between 1995-2005 were searched. In addition to this the database where general practitioners report their cases as well as the cases with botulism reported to the insurance companies were included. The results of this study show that only 0,03 percent of the Swedish horse population has been diagnosed with botulism during the time period this study covers. In all the cases included in this study the diagnosis was made based on clinical signs and in none of the cases verification by isolating the toxin was possible. In all cases where forage is noted in the journals the horse has been feed haylage which indicate that there is a connection between the use of haylage and botulism. Three horses died despite being partially vaccinated against botulism type B which indicate that a correct vaccination has to be done before the horse get any protection or that the correct diagnosis was not botulism type B..

The Sami people are a national minority in Sweden, but are also considered as native citizens of Sweden, Norway, Finland and Russia. The world has however a very limited knowledge about the Sami?s and their cultural background.The aim of this proposal is to examine six different history schoolbooks which depict the Sami people in Sweden. In addition, one of the key elements of this proposal is to understand how the selected literature represents the Sami people.Lastly, the proposal also seeks to review if the literature in the schoolbooks represents the elementary curriculum goals (Lpo94).The selected method was to do a text analysis of the literature and to illustrate that is presented in the reviewed schoolbooks. The text analysis is completed with an analysis of the illustrations and pictures that are presented in the selected schoolbooks.The key findings were that the review in majority of schoolbooks has stereotypical descriptions of the Sami people. The Sami people are generally depicted with the hut and the reindeer management in majority of the reviewed schoolbooks.The research about the Sami people is inappreciable in majority of the reviewed literature. In addition, the Sami people are often presented in connection with ?other? history, such as the silver ore in the mines or the territory dispute with settlers from the south of Sweden.

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

The main aim of this paper is to illurninate how a group of immigrants meet the publiclibrary in Sweden. I have chosen to discuss Iranian immigrants' meeting with the publiclibrary in Borås. The investigation (qualitative interviews and inquiries) has taken placein the public library of Borås and partly in a local library with high density of immigrants.A theoretical perspective deals with the case study of dual marginality, where theconception of the "Marginal Man" or "The Outsider" is central. I have indicated how theprevious authors have considered this problem, to live on the verge between twodifferent cultures and how individuals react on it.The interviews and inquiries answered by Iranian immigrants are the most importantmaterial in this investigation and the result of them is connected to the theoreticalperspective and a discussion, what it means for the public library..

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.
