Making Money in a Dirty Business
Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters.
The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.
The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness
In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production.
The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.
Landskapsurbanism i en Post-Industriell kontext
I examensarbetet ?Landskapsurbanism i en Post-Industriell kontext? diskuteras den relativt nya diskursen kring ?Landscape Urbanism? eller ?landskapsurbanism?. Arbetet fokuserar på platser som har övergivits av industrin, i skenet av den post-industriella utvecklingen. Huvudmålet med studierna av ämnet är att belysa ett antal ?landskapsurbanistiska metoder? och sedan tillämpa dessa på min plats: den gamla Cementafabriken på Övägen i Limhamn, Malmö.Den största inspirationskällan i detta är den amerikanske landskapsarkitekten James Corner´s teorier, och de metoder som utövas av hans landskapsarkitekturbyrå; ?Field Operations? i New York.Eftersom ämnet täcker in väldigt många aspekter och problemställningar rörande samtida urban planering och design, har jag i enlighet med Corner delat in min text under fyra rubriker:- Processes over time- The Staging of surfaces- The Operational or Working method- The ImaginaryDet gamla cementfabriksområdet har förvärvats av byggbolaget NCC, och kommer inom en snar framtid att bebyggas med bostäder.
Marklyft som behandling mot långvarig ländryggsmärta: en Single Subject Experimental Design
Background: Low back pain (LBP) is a common disorder in the western world. A majority of those afflicted by a first acute episode is at high risk of developing sub-acute or persistent symptoms. Persistent LBP can be caused by pathological changes in the discs and disturbed neuromuscular activation, which can cause hypotrophy of the extensors strong type-2 muscle fibres. Deadlift (DL) is an exercise that may correct all these pathological transformations. Aim: To investigate the effect of DL-training on patients with persistent LBP.

En rankings efterskalv : Om Transparency International och svensk korruption
What impact and effects are created by the placement of an international ranking? Could it be that a top rank is detrimental to an entire country's efforts to fight corruption?This bachelor thesis in political science is about Swedish corruption. In essence, so questioning the Transparency International's indexed rankings that placed Sweden in third place. Issues concern since if the third placement has created nonchalance and a careless mentality in Swedish government and in particular in the municipal operations. Research results show that Transparency International's rankings have low validity and low reliability and that the government is not acting sufficiently to prevent and fight corruption.
Interaktion med surfplatta och traditionella leksaker inom förskolan : En studie av likheter och skillnader ur ett socialt- och lärandeperspektiv
The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.
Saltsjöqvarn : Utbyggnad av staden, ombyggnad av industrin
I denna rapport behandlas verktyget FMEA (Failure Mode Effect Analysis), dess användning och genomförande på identifierade komponenter som ingår i elmotorer tillverkade hos ABB LV Motors i Västerås. Målet med detta arbete har varit att ge lärdom om metoden FMEA på företaget för att möjliggöra användandet av verktyget bland medlemmarna på företaget och att vi implementerar verktyget på befintlig motor för att analysera de felsätt som kan uppstå. Eftersom ABB just nu har ett pågående projekt med en ny motor kan våra slutgiltiga felanalyser även ge dem information om vilka ändringar och åtgärder som kan vara till nytta vid utformningen av den nya motorn.Efter två veckors praktik i verkstan och en grundlig genomgång av företagets reklamationer kunde vi avgränsa arbetet genom att identifiera de komponenter som analyserna skulle genomföras på. Efter en genomgång tillsammans med våra handledare på företaget kom vi fram till att utföra våra analyser på fem komponenter, två av dem framstod som mycket kritiska som upptäcktes redan vid genomgång av reklamationerna.Komponenterna som vi har analyserat är:1. Lager2.
En grupp ungdomar i tvångsvård: bakgrund, begåvning och självbild
The aim of this study is to describe a group of youths in compulsory care at a SiS institution in the south of Sweden. The study focuses on intelligence (measured with WISC-III) and self-report, i. e. what the youths think of themselves (measured with Jag tycker jag är). Attempts were made to see if background factors (based on information from the standardized ADAD-interview) seem to be coherent with intelligence and/or self-report and if so, what those background factors are.

Röstningsbeteende i utsatta bostadsområde : En studie om hur social miljö påverkar valdeltagande
Already in 1988, different levels of participation in the election between different districts of big cities in Sweden were noticed. The problem with low political participation in specific areas has almost always been theoretically explained through an individual perspective. This study is therefore focusing on the problem from a contextual perspective. The hypothesis for the study is as follows, in the case of Malmö the level of participation in elections are affected by social environment in which segregation will be the single highest factor. The dependent variable, participation in the election was tested by the independent variables representing social environment; origin, education, gainfully employed and income.
Transferfunktionsmodeller modellering och prognoser av Sjötransportindex
We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.
Radialtätning till Retarder
This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.
