Genetic diversity of Roseroot (Rhodiola rosea L.) from Sweden, Greenland and Faroe Islands

Roseroot (R. rosea L.) has gained more attention the last years, mainly because of its phy-topharmacologic properties. Even though many reports in roseroot have been published, only a few articles are dealt with the genetic diversity. The Nordic Genetic Resource Center has collected Roseroot material from Sweden, Greenland and Faroe Islands under different expeditions. The samples were analysed to study the genetic diversity study.

Realtidspositionering med WLAN för multikanalsljud i scenmiljö

Multikanalsljud, surround, har ökat i popularitet de senaste åren och har gått från att vara en upplevelse som endast kunde fås på biograf till något som finns i många människors vardagsrum. Formatets styrka är att den upplevda rumsupplevelsen ökar samt att olika ljudkällor kan få större och bättre separation. Då man sammankopplar det visuella intrycket av en persons position med det ljudande får lyssnaren lättare att separera olika ljudkällor. Upplevelsen blir därmed mer lik den situation som uppträder i verkligheten. I detta arbete ville vi hitta en praktisk lösning som möjliggör att surroundljud också kan erhållas ur livesituationer, t.ex.

STUDENTERS INFORMATIONSHORISONTER: Användning av Google och sociala nätverk i informationsökningsprocessen

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

Det ligger en heteronormativ bok i din säng mamma! En intervjustudie av hur några kvinnor i samkönade relationer upplever informationssituationen rörande graviditet och föräldraskap.

Studies of the information needs of library patrons are necessary in order for the library to serve the community. Alas, studies of non-heterosexual persons are rare in the field of Library and Information Science in Sweden. This study aims at examining the information situation of women in same-sexed parenthood by means of analysing their situation as norm-breaking. The study is done through examining the specific information needs of this group, how they seek and receive information, what barriers they encounter and what function the library has in this information situation. A queer theoretical approach to heteronormativity in combination with McKenzie?s two-dimensional model of information seeking is used to perform a qualitative analysis of the material.

Den förlorade dialogen. : Smartphone under arbetstid.

This paper aims to create a better understanding for how executing private matters during work hours affect the individual worker. In todays world the access to social medias, the Internet and all your friends is easy to access due to smartphones and computers. Prior research as described this both as a threat against the productivity of the worker and the moral of the workplace. While others mean that it is a source of recovery and something positive.This thesis uses a qualitative method and fifteen interviews where conducted with people between 20-30 years, who where working and living in Sweden. The theory of this paper is built on following areas: Time, the line between work and private, together alone, the brain and the affect it has on the dialogue between colleagues.

Liszt och Alkan: Den virtuosa pianoetyden : Övningsstycke eller muterat monster?

Anders Rådén: Liszt & Alkan: the virtuoso piano study ? practice study or monstrous mutation? Uppsala: Musikvetenskap, 1998. C-uppsats (60 p).The purpose of this essay is to analyse a selection of studies by Franz Liszt (1811-1886) and Charles- Valentin Alkan (1813-1888). Can they be definedas practice studies, or are they reshaped in such a manner, as to establish a larger form reminiscent of the concert study? First of all, typical study characteristics of this time period are determined, then such characteristics are looked for in three of either Liszt's and Alkan's studies (from Douze grandes études S137 and Douze études dans les tons mineurs Op.

c-cytokromer hos den (per)kloratreducerande bakterien GR-1 : samt en jämförande studie av c-cytokromer från GR-1, Ideonella dechloratans och Dechloromonas aromatica

Arbetet beskriver en analys av innehållet av membranbundna och periplasmiska c-cytokromer hos perkloratodlade GR-1 och jämförelser med c-cytokrominnehållet hos Ideonella dechloratans och andra kända c-cytokromer, samt med genomet för Dechloromonas aromatica. Den jämförande studien av c-cytokromer gjordes med syftet att undersöka en hypotes om att bakterierna använder olika vägar för elektronöverföring till det periplasmiska enzymet (per)kloratreduktas. Cellmembran från GR-1 renframställdes genom ultracentrifugering och periplasma preparerades fram med hjälp av osmotisk chock. Fraktionerna analyserades sedan med SDS-PAGE och peptider med kovalent bundet hem (c-cytokromer) detekterades med hjälp av en specifik färgreaktion. Även Touchdown PCR med degenererade primrar genomfördes på isolerat DNA från GR-1 i ett försök att finna en gen kodande för ett NapC/NirT-liknande protein.

Provmetod för olje- och partikelöverdrag från kompressor till tryckluftssystem

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Ledarskap, kommunikation och målsättning som motivationsfaktorer : en fallstudie på Fresenius Kabi i Uppsala

It's not a secret that most companies strive to get such a high economic return as possible. To successfully engage in a profitable enterprise, there are many elements that come into play. An important element is the motivation of the employees and their work performance. Work motivation is a key factor for the employees to improve their performance and therefore determinant for the successes of the company.This work is a case study in the production at Fresenius Kabi, Uppsala. The work is based on an employee survey that they fill out once a year and the aim is to develop a deeper understanding for these questions and how the employees see on leadership, communication and goal-setting as motivators and how these factors works in the company today.To get this deeper understanding I have used a qualitative approach.

Energieffektivisering av industribelysning : Planering av belysningsanläggning i mekanisk verkstad

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Folkbibliotekens förmedling av Internetresurser: En undersökning av två mångkulturella länksamlingar.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

Teamwork och det nya ledarskapet - en begreppsanalogi

The purpose of this essay is to further the understanding of contemporary management theory by conducting an analogy-study of the source to many of the terms today used in knowledge-intensive companies. The way a football club deals with knowledge work differs from how a conventional company deals with it. However, many of the terms, such as teamwork and coaching, are shared by the two types of organization. By using the analogy-method we hope to create a wider understanding for the shared concepts. We have used a hermeneutic perspective throughout the essay, which first and foremost means that we focus on understanding and explaining social phenomenons.

Vaktelproduktion för ägg och kött

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production.

Attitudes concerning conservation in two different wildlife areas in Kenya

All over the world, scientists agree that to succeed with a conservation project, it is important to have a good relationship with the local people. If they do not receive a good impression of the project, they will not be willing to collaborate and the project will probably fail. According to previous studies, there are different factors affecting attitudes to conservation, like the level of education of the participant. Many studies have shown that the higher education the people have, the more positive attitude they have to adjacent conservation areas. Economical factors are also important, it is often stated that having more money results in a better attitude.
