This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow.  Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.

En hel del av forskning inom kognitiv neurovetenskap tyder pa? att effektivare uppla?gg av repetitionstillfa?llen fo?rba?ttrar inla?rningsprocessen hos eleverna, eller ra?ttare sagt hos ma?nniskor i alla a?ldrar.Uppsatsen handlar om yngre instrumentalelevers inla?rningsprocess i relation till hja?rnans minnesfunktioner och underso?kningen fokuserar fiolundervisning pa? nybo?rjarniva?. Jag har utfo?rt ett empiriskt experiment av tajmade repetitionstillfa?llen via interaktiva onlinebaserade samtal med tre yngre elever.Alla de tre eleverna har under projektens ga?ng a?stadkommit fo?rba?ttringar av de fa?rdigheter som stod i fokus vid de tajmade repetitionerna. Experimentperioden har haft positiv inverkan pa? elevernas motivation, men deras uppna?dda fo?rba?ttringar bedo?mer jag vara av icke besta?ende karakta?r.

A study of paleomagnetic remanence and anisotropy of magnetic susceptibility (AMS) has been performed on the Öje-Diabase in Dalarna, Sweden, and on basic dikes associated with the alkaliquartzsyenite/granite Noran-pluton in central Sweden. Based on isolation of directions of characteristic magnetization in the basic rocks, a division into three different groups (A,B,C) has been made. Group Aconsists of dolerites of Jotnian origin, both dolerites from the Öje-Diabase and dikes associated with the Noran-pluton are included in this group, making them coeval. Group B is suspected to show a re-magnetization from the later part of the Svekonorwegian orogeny. Group C belongs to the Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of dolerites revealed two different types of demagnetization behaviours, one where magnetite clearly was the source of the remanence, and an other with a linear decrease in magnetization intensity. The measurements of magnetic anisotropy reveals a magnetic fabric with an almost horizontal foliation and a lineation that indicates a fairly uniform NNW/ S-SE flow direction of the magma..

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Background: The value of stock recommendations have been debated for a century andthe debate has escalated since Alfred Cowles (1933) published his research in ?Can StockMarket Forecasters Forecast?? As of late, savings in stocks has increased and the householdsare managing their savings more actively. The consequence of the increased interestin stocks has resulted in a growing market for stock recommendations. Not just financialmedia but daily newspapers have embraced this new found interest, hence stock recom-mendations can be found in almost all large newspapers in Sweden. Furthermore, this phe-nomenon has also lead to intensified research within stock recommendations.

The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition. The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet. Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management. More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

This two years master?s thesis consists of a domain analysis on the local Swedish newspaper Gefle Dagblad (GD). The domain analysis was developed by the Danish library and information scientist Birger Hjørland. The purpose of this theory is to understand the information behavior of individuals by studying the social and collec-tive context which surrounds this person. According to Hjørland, four different areas need to be studied in order to analyze a domain.

This report describes work on the thesis ?IT systems and organizational development?. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization.

Container Security Initiative was launched in 2002 by the US Customs and Border Patrol in order to secure the global flow of containers destined for USA. This thesis attempts to analyze Container Security Initiative in relation to a possible future scenario made by the weapons industry where the state's global traderoutes are being subject to militarization. A development which is partly based on the threat posed by global illegal trade. The latter is discussed and defined based on current research made by Carolyn Nordstrom, Moíses Naím and theories on the cosmopolitan perspective made by Ulrich Beck. Strategy documents concerning Container Security Initiative are then analyzed in terms of discourse to try to say something about what the program indicates.

The aim for this thesis was to develop a proposal of documentation, containing rules and procedures, which JernströmOffset needs to acquire the Certified Graphic Production certification. A fundamental part was to study the materialissued by Sveriges Grafiska Mediaförening, to clarify the requirements that must be met to obtain the certification. Therecommendations found in the CGP material must also be considered.Based on the requirements and recommendations of Certified Graphic Production, a mapping of the workflows atJernström Offset was performed. It was done by interviewing employees from different departments at the company,this to get a clear understanding of the operations carried out throughout the production flow and the final qualityfollow-up.During our reviewing process we found that a number of changes, in terms of working environment and practices,must be made at the company. As a result of this we propose some appropriate actions to be implemented.The documentation was finally written, through the requirements and recommendations of Certified GraphicProduction and then applied to Jernström Offset?s work procedures..

In this project a washing station has been constructed for Albany International AB. At present, there is no existing system to clean the dirty pipes that are coming back to the company.The work followed the product development process, and it started with the requirements list. This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

Digitalt textiltryck ger mig möjlighet att skapa textilier av hög kvalitet i små upplagor utan begränsningar vad gäller rapportstorlek och färgantal. Jag kan producera hållbara och praktiska textilier med en handgjord känsla. Dessa egenskaper ger tekniken intressanta möjligheter som en överbryggare mellan design och textil konst/konsthantverk. Det ger också stora möjligheter att anpassa formgivningen efter en specifik möbel eller miljö. Detta vill jag utnyttja i mitt arbete.

Face-to-face communication is always complemented with non-verbal signals that give us clues as to how a message shall be interpreted, but as communication is moved online the possibilities to express oneself becomes more limited.This paper focuses on the instant messaging client Windows Live Messenger and three of the non-verbal functions that it provides (nudges, winks and emotes). The purpose of the paper and its underlying study is to compare the senders' intentions with the receivers' conceptions when it comes to these functions.The study was done as a questionnaire with two different versions of the questions, one looking at the senders' intentions and the other at the receivers' conceptions.The results were then compared in order to look for tendencies. The results showed that the most common intention among the senders was also the most common conception among the receivers, but that the rest of the attitudes didn't match at all. The functions that are supposed to help the conversation flow often create ambiguity instead and lead to vagueness, misconceptions and annoyance..
