Utveckling av en LC-MS-metod för analys av gamma-hydroxibutyrat, gamma-butyrolakton, 1,4-butandiol, amfetamin och metadon

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Etablering av höstraps i mellansverige :

The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden. There are many factors that influence the outcome of the establishment, e. g.

Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

FE-modellering av hjullast på sandwichpanel

This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.

Metod för urval av bäriga bestånd längs med bäriga vägar i Sveaskogs planeringsområde Råneå och Överkalix :

With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity. The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program. The method resulted in four different themes: 1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections. 2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.

Aktivitetsbaserade kontor : En studie kring hur Vasakronan implementerat det aktivitetsbaserade kontoret och arbetssättet

Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.

Multikriterieanalys av potentiella konflikter vid markanvändningsplanering - Naturstenbrytning i Lysekils kommun

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

FN-organisationens inflytande över demokratiseringsprocessen i Kosovo

In my paper I have examined the United Nations role in the democratization of Kosovo. In order to complete this purpose I have asked two questions? How has the UN contributed to the democratization of Kosovo that has taken place so far?? What advantages and/or disadvantages has the UN presence in Kosovo had from a democratic perspective?The method I have used in my paper is a qualitative one, and more specified a qualitative text analysis. This means that I have examined a rather small number of sources, but in return I have analyzed these sources very carefully. In addition to the choice of a qualitative method I have used Robert A.

Kryptosporidieinfektion hos nötkreatur : utvärdering av en ny metod för påvisande av subklinisk infektion

Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

Modellering och simulering av det evaporativa bränslesystemet i en personbil

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

?Den frivillige soldaten.? : Manlighetsideal och legitimitet bland svenska frivilliga soldater samt det omgivande samhället under finska inbördeskriget 1918

This paper examines how the ideal of manhood is portrayed and constructed and how the participation of Swedish soldier volunteers are motivated and legitimatized. The purpose of this examination is to gain understanding and knowledge about the Swedish soldiers in the Swedish brigade, how they legitimatize and motivate their participation and how the ideal of manhood is portrayed and constructed. The study is based on material from the war archive in Stockholm. The empirical material is composed by letters and propaganda material. In the analysis of the empirical study, there have been two theories used which are Eric Hobsbawms historical method and theory about invented traditions and Peter Aronssons historical method and theory about ?historiebruk? and legitimacy.

The method used to meet the objective was qualitative. The qualitative study was conducted with a hermeneutic basis, where individuals were asked to describe their experience of empowerment and how they feel affected of it. This thesis has a deductive approach, where existing theories dealing empowerment formed the basis for the design of interview substrate, which is then paired with the empirical evidence, based on this the conclusions was drawn.Result & Conclusion:What separates the different kinds of empowerment and how it affect the staff depends most of all on how the management chooses to communicate and share information with their staff.Suggestions for future research:A study regarding managers that works with different kinds of empowerment, and how that affects them, could be regarded as an interesting future research.Contribution of thesis:It shows that different kinds of empowerment affect the staff in different ways, which I made clear to the readers.Keywords:empowerment, thinking skills, relations and organizational - structure and theory.

Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus

Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.
