Karriärmöjligheter inom Arbetsförmedlingen : En kvalitativ studie om hur de anställda upplever sina karriärmöjligheter
This qualitative study aims to examine what career opportunities the Swedish employment service Arbetsförmedlingen can provide, as well as how the employees perceive their career development opportunities. Furthermore, we have touched on what it is that makes employees feel satisfied with their job and workplace, and also stay in the organization. The study was conducted on one of Arbetsförmedlingen?s offices in northern Sweden and the informants consisted of six employment agents, an executive assistant and a head of division. The result of the study has been analyzed using theories within the field of career development.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Hur ökad fukthalt påverkar pannor
This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.
Kommunala roller i megaprojekt - Lunds kommuns hantering av ESS-projektet
The aim of this thesis is to investigate how municipalities handle planning of megaprojects. The term megaproject here refers to a large project in terms of time, space, investments, numbers of agents etc. With an increasing importance of the phenomena the need of discussing the role local politics could take in this process is important.How do municipalities handle the difficulties that come with megaprojects and what roles do they take in their work with megaprojects? These empirical questions are tested on a case where the municipality of Lund works with the megaproject European Spallation Source (ESS). A theoretical question discusses the megaproject in the light of governance and government, and structures the analysis around these two important terms.Different parts of the municipality handle there part of the planning from there own logic.
Debatten som inte förekom
The purpose of this paper was that through discourse analysis look at how gender and the equality debate is created between two head debaters and commenter's on a forum. We have used Norbert Elias and John L. Scotson´s (1999) theory about Established and Outsiders to see power struggles between groups in the debate. With Jonathan Potters analysis tools in his book Representing Reality (1996) we were able to analyze the debate texts. Using discourse psychology, we were able to see how people use tactical discourse in their texts to represent themselves and the world in different ways.
Samme Fader han dock Bliver : En litteraturstudie angående gudsbilden i två barnbiblar
This is a comparative literature study between two children?s bibles and the Swedish Bible. The study compares three stories from the Bible with the children?s bible versions of them. The purpose of the study is to see whether God is portrayed differently in the children?s bibles, and if so, in what way.

Studier av nitreringskinetiken för järn-kromlegeringar i
ammoniak-vätgasmiljö
Kinetiken för nitrering av en järn-kromlegering med en gasblandning av ammoniak och vätgas har studerats vid temperaturer mellan 500°C och 600°C. För ett gasatomiserat pulver (Fe-7%Cr) har inverkan av syrepotential (H2O/ H2) och olika förbehandlingar (förreduktion och förnitrering) studerats med hjälp av en termogravimetrisk metod. Dessutom har laserablering som förbehandlingsmetod för nitrering av solida ytor studerats med hjälp av GD-OES-analys (Glow Discharge Optical Emission Spectrometry). Resultaten har diskuterats och tolkats med avseende på faktorer som kan påverka ytreaktionens hastighet, kärnbildningsförhållanden samt diffusionsvillkor. Syrepotentialen har visats påverka nitreringshastigheten via komplicerade samband mellan syrepotentialens storlek, kvävehalt i materialet och nitreringstemperatur.
Att mäkla på Franska Rivieran som svensk till svenska kunder. Vad skiljer sig från att mäkla i Sverige?
Att mäkla på Franska Rivieran som svensk till svenska kunder skiljer sig från att mäkla i Sverige. Exempel på det är att man använder sig av ett juridiskt ombud, en notarie vid kontraktsskrivning i Frankrike. Där förekommer heller inte budgivning då detta är olagligt. Istället förekommer ofta prutning mellan köpare och säljare. Mäklaren arbetar även ofta närmare köparen än i Sverige, då man hjälper denne med kringtjänster som t.ex.

Barnfattigdom 2012 : Ett levande problem i Uppsalas skolor
In this essay we aimed to find how economic scarcity among children and youth presents itself in school, according to how school staff experience it. We have conducted interviews with student welfare staff to hear their experiences of this subject and how the schools try to help these pupils. We have used interpretative phenomenology as a base for our work. We have also used some of this traditions most important notions along with notions of Erving Goffman and Sara Ahmed during our processing off the material. With help from these, we report our most interesting results. We have seen that a lack of resources exists among youth today and that everyone not has easy access to things many of us might take for granted.

Stubbehandling med pergamentsvamp och urea mot sporinfektioner av rotticka i bestånd av hybridlärk
Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.
Förebyggande av postoperativ myalgi
Succinylcolin är ett icke-depolariserande muskelrelaxantia som används inom anestesisjukvård. En vanlig biverkning är postoperativ myalgi. Varför smärtan uppstår är inte helt klarlagd. Under många år har forskare runt om i världen försökt komma till rätta med problemet utan att helt lyckas.Olika läkemedel och strategier har prövats. En av de viktigaste uppgifter en sjuksköterska har är att förebygga och lindra lidande.
Hur skiljer sig tjockleken på retinas nervfiberlager mellan emmetroper, myoper samt hyperoper? : En OCT studie
Syfte: Syftet med studien var att utreda sambandet mellan ögats ametropi och tjockleken på retinas nervfiberlager (RNFL) med optical coherence tomography teknik (OCT).Metod: I studien ingick 30 försökspersoner med olika typ av ametropi. En inledande mätning med autorefraktor genomfördes och styrkorna värderades därefter av i provbåge. På så sätt erhölls ett resultat på storleken på den eventuella ametropin. Därefter utfördes den huvudsakliga mätningen av nervfiberlagets tjocklek med OCT kameran OPKO Spectral OCT Slo på samtliga försökspersoners högerögon. Försökspersonerna delades in i fem olika grupper utifrån befintlig ametropi.Resultat: En signifikant korrelation mellan ögats ametropi och det retinala nervfiberlagrets tjocklek hittades då resultaten från alla 30 försökspersoner analyserades mot varandra.
