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.

Background: Today, It?s not uncommon that international companies and organizations have a higher turnover than the GDP of developing countries. Consequently, this may suggest that the choices companies make in the context of their business has a great potential to influence the world from an economic, but also from a social and environmental standpoint. From this the notion emerged that companies have a responsibility, referred to as Corporate Social Responsibility (CSR). A clear definition of the CSR concept is difficult to find, more than 37 different definitions has been identified.

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..

Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

There is little knowledge about abuse of anabolic androgenic steroids (AAS) in Sweden. Thispaper aims to explore, from a discourse psychological angle, how persons with experience ofanabolic androgenic steroids (AAS) construct there identities.The theory and method used as a frame for the paper is discursive psychology, depending on thefocus in the paper of human beings use of language in the construction of identities. Forcollection of data interviews were made. The six respondents al had experience of use of AAS.The interviews illustrated how users of AAS speak about AAS, and create there identity, inrelation to AAS. In the interpretation of data we used two different tools, used by discursivepsychologists, interpretative repertoires and subject positions.

AbstractDespite that e-business nowadays is established scepsis against it amongst consumers exists. We, as consumers, suppose that this skepticism is caused by bad communication from the e-business companies. This has lead to our suggestion that some con-sumers refrain from e-business because of bad communication or deficient trust.Our purpose with this paper was to investigate factors of communication between companies and consumers within e-business (B2C) from the consumers? point of view. We thereby have drawn conclusions regarding consumers? choice of e-business company.

In the light of ever increasing international trade around the globe, affecting men and women in all countries, it is surprising that so little attention is given its gender effects. The effects of trade are said to be gender neutral, but could potentially act reinforcing on the existing gender patterns in a society. The aim of this thesis is to examine whether the implications for men and women in relation to trade liberalization can be found to differ. By stylizing some differences between men and women, this is done by examining the theoretical implications mainly via the Heckscher-Ohlin model and through a Beckerian approach. The implications found are then compared with the findings in existing empirical work.

The purpose of this study is to investigate teachers 'and students' understanding of why students finish school with incomplete scores and which resources they consider necessary for students to accomplish the goals that are set for the students. Owing to the reuse of pupils and teachers' experiences, this study will highlight significant qualitative aspects of work with students who finish school with incomplete high school grades. Hopefully, will this study be a support and information base in secondary school.The material forming the basis for the report's theoretical assumptions and the basic assumption is based on Lev Vygotsky sociocultural perspective on learning that Olga Dysthe discuss and develop further in his book, Dialog, samspel och lärande.  The present work is based on qualitative research method. I selected this research method because I am interested in getting an understanding of the importance and significance of this research The study applied a qualitative interview format.As a result of the investigation as it has appeared that students difficulties to achieve the goals,depends on several factors, mostly on the student's socio-economic and psychosocial situation they live in. The life situation of the students determines the learning and knowledge process and how they reach their goals.

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.

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

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 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.
