Smileys roll i kommunikation mellan ungdomar över det digitala mediet
Detta examensarbete behandlar användandet av smileys och deras roll i kommunikation mellan ungdomar över det digitala mediet. Hur ser användandet av smileys ut bland ungdomar? Vilken mening lägger sändare respektive mottagare i användandet av smileys? Går det att kategorisera och gruppera användarna av smileys utifrån ålder och kön? Denna uppsats behandlar chatt och det chattspråk (innehållande smileys, förkortningar och asterisker) som dagens ungdomar - generation Z, använder sig av dagligen framför sina datorer. En enkätundersökning bland elever vid två år 6-9 skolor och en undersökning via två diskussionsfora på Internet, ligger till grund för resultaten till denna uppsats. Resultaten visar att smileys används som ett uttryck för känslor, sinnesstämningar, ansiktsuttryck, kroppsspråk och tonfall..
Nytt spritsrör på TwinRoll typ TRPE : Undersökning av kostnad på spritsrör
This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.
För ändring. En undersökning av tidningen i iPadformat
My work has been to create a magazine for iPad to explore this format, whichthere are mixed feelings about. Instead of seeing the digital format as an enemy ofthe printed magazine, I have chosen to see it as an opportunity.I have given myself the task of designing a magazine that can justify the useof the digital magazine. I have looked at the identity of the magazine, but mainlyexplored the format and its prerequisites.I was triggered to do the project when I saw people who are just making a pdfof the printed magazine and publish it digitally. I have during my work discoveredhow near or far away you can be from the printed magazine.The format of the iPad has multiple aspects to look upon; one that turned outto be clear in my project was navigation. Working with a spread has its problemsand opportunities; the same applies to an article that is larger than a screen.
Uppköpta familjeföretag : Hur har organisationskulturen förändrats?
Familjeföretag är den dominerande formen av företag i både USA och Sverige, men endast en tredjedel av alla ?första generationen? familjeföretag förs vidare till nästa generation och endast 15 % av dessa förs vidare till tredje generation. På senare år har det blivit vanligare att företagen säljs vidare utanför familjen men det har inte forskats kring hur kulturen påverkas av ett uppköp av en extern part.Syftet med uppsatsen är att påvisa om och i så fall hur kulturen i ett familjeföretag förändrats vid uppköp av en extern part.För att uppfylla uppsatsens syfte har ett kvalitativt, hermeneutiskt tillvägagångssätt använts. Vi har genomfört fallstudier på tre företag där ett före- och efterperspektiv på kulturen har studerats genom kvalitativa intervjuer och observationer.Resultatet av forskningen visar att kulturen i tidigare familjeägda företag förändras vid uppköp av en extern part. Hur kulturen förändras beror på de nya ägarnas värderingar, prioriteringar och mål..
"Dom kallar oss invandrare!" : En undersökning som bygger på hur ungdomar av "andra generationens invandrare" identifierar sig själva.
This investigation is aimed to analyze and gain insight into how young people of the "second generation immigrants" identify themselves in a society where they are seen as immigrants of the environment in view of the name. Also, how they identify themselves during trips to their home/country of origin are of relevance to see if they are affected in their own identification, depending on how they believe they are seen from the outside.Through a survey, the statistics were produced, which serves as a preliminary to the larger part of the investigation where six individuals were interviewed in order to give deeper answers to the questions sought. The answers that emerged were then analyzed in relation to selected theories.In connection with the investigation it has emerged that the young people in question often identify themselves in such a way that they think that the surroundings look at them. It is in relation to how others see them as they see themselves, which creates a distance between the surroundings and themselves. With increased knowledge on both sides, this distance between the environment and the young people in this investigation maybe could reduce..
Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie
This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.
"Det är svårt att få dem att stanna längre än tre år" : måste rekryteringsprocessen förändras för att tillfredsställa unga medarbetares krav?
How does a corporation work during the recruitment phase to entice and motivate younger members to work for their organization?The aim is to examine in which grade corporations and organizations? recruitment needs to adapt to encounter Generation Y on the labour market.The base in our method is abduction and our research is based on a qualitative method. We have fulfilled interviews with corporations such as Scania, Skatteverket, Swedbank and Appelqvist & Ottoson HR AB.Corporations need in a sense change their recruitment and emphasis their resources to sell the whole corporation and its image to the young job applicant. The younger members demand a total impression of the corporation to implement an interest and to get motivated to work there. Together with our respondents we have realized that Generation Y has higher demands on their workplace than earlier generations..
Utveckling och validering av en LC-MS/MS metod för kvantifiering av clopidogrel och dess metabolit i plasma
Clopidogrel is an antiplatelet substance that prevents blood coagulation in the arteries. It is an inactive pro drug that becomes activated after first-pass metabolism by the liver. The active metabolite of clopidogrel is 2-oxoclopidogrel, which is unstable therefore pharmacokinetic data is obtained by measuring the inactive metabolite clopidogrel acid in plasma. Clopidogrel is taken orally in tablet form. The aim of this project was to develop a LC-MS/MS method for quantification of clopidogrel and its metabolite in plasma. The method has been developed by optimizing the sample preparation.

Generationsmotivation? En kvantitativ studie om generationsspecifika motivationsfaktorers vara eller icke vara i arbetslivet
Följande studie är en personalvetenskaplig uppsats som behandlargenerationsspecifika motivationsfaktorer. Syftet med studien är att undersöka huruvidatillhörigheten till en särskild generation medför ett specifikt förhållningssätt till det egna arbetet, dvs. om några skillnader existerar generationerna emellan. Med hjälp av en undersökning utifrån en svensk kontext är vår förhoppning att genom vår studie kunna tillföra utökade kunskaper inom området.Teorin som uppsatsen baseras på berör tre huvudsakliga områden; motivation, generation samt en sammanslagning av de två begreppen. Motivationsbegreppet sett ur ett allmänmänskligt perspektiv är omfångsrikt och definierat på ett flertal olika vis, men saknar täckning för mer specifika kontexter.
Naturliga filtermaterial för reduktion av metaller i dagvatten
Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..
Konsekvensanalys av dammbrott vid Tjärnviksdalen
This report consists of an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map where the water level has been raised to the level that the County Board of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .
LAN-Uppgradering
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg
The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.
Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam
Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.
