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.
It´s a way of understanding the universe while leaving the universe unexplained : Sökandet efter det autofiktiva jaget i Jeanette Wintersons Oranges Are Not the Only Fruit
In this essay I examine the auto fictive self in Jeanette Wintersons Oranges Are Not the Only Fruit. I do this through a close reading of the novel using Mieke Bals narratological terms;narrator, story, fabula, time and order. These narratological terms have been merged together with central themes of the book. I look at the readers understanding of the novel, the relation between fairytale and realism, symbols, intertextuality, the mother-daughter relationship and silences and I analyze these themes in their relation to autofiction and the auto fictive self. Gemma Lopez Seductions and Narratives has been a key reference, mainly her theories on self-creation in narratives, and the construction of the self, trough language. The narrative is the place where the self can transgress and reshape, which gives the narrative a subversive power. I analyze this presumed power, and look at how the story shapes an opportunity for the subject to see itself.

The project was initiated by Medipharm which produce microbial inoculants which used
as additives to preserve forage. The main goal was to test three inoculants to produce
maize silege. The following Medipharm produced inoculants were tested, Milab 393,
Lactisil Wolecrop II, Lactisil 300 2. An untreated control was included in the study. The
trial was done at Swedish university of Agriculture and Science in Alnarp, Sweden.
Eurostar was the cultivar of the maize and was grown on 20, 5 hectares.
Sambandet mellan saldodifferenser och effektiva materialflöden : Fallstudie utförs på Atlas Copco?s logistikavdelning
Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.
Studenternas bankmarknad; en förändrad studentpopulations förhållande till banker

Utvärdering - till vilken nytta? : En studie om hur utvärderingar användas och vad som gör dem användbara
Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.
Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.
Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.
Frysa livsmedelsrester eller kassera dem för biogasproduktion : En studie, ur livscykelperspektiv, av energianvändning och växthusgasutsläpp
Food is widely consumed and in 2011 an average American devoured approximately one ton of food. The production of these goods requires large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the waste generated by households. 60 % of this food waste could be avoided if the eatables were handled in a better way.Avoidable food waste arises partly because residues from food are not taken care of, and because the food is not stored in a way that optimise its durability. Residues arises part- ly because of the contradictory and complex demands of everyday life and are, because of our busy lifestyle, difficult to avoid.
Påverkande faktorer vid implementering av CRM
The purpose of this thesis was to examine why so many CRM-projects didn`t reach the expected goals that companies management envisaged. The purpose was divided into two research questions. ? How should companies? management design the strategic projection of the CRM implementation? ? How will employees? attitude to changes influence the result of the CRM implementation? The case company was a Swedish technical consulting company: interviews were conducted with two represents from two different departments. The findings of the study were that management often strongly believes that software will sort out most of the upcoming problems and forget the factor that education of employees is at least equal important.

Läraren - från ensamvarg till lagarbetare? : En studie av hur lärarrollen har definierats och förändrats i grundskolans läroplaner från 1962 till 2011.
Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.
