Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).

Since the 1970s voting behaviour has changed. Party identification and class voting has declined. As the electorate becomes more volatile, campaign strategy and party image becomes essential. Political communication and mass media now play an important role in election campaigns. Therefore, researchers take an interest in the impact of media on public opinion.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

Bakgrund: I dagens samhälle har varumärken kommit att spela en allt större roll för såväl konsumenter som företag. Varumärken fungerar som en ledsagare i individers sökande efter identitet och samtidigt som en gemensam nämnare eller tillhörighetsfaktor inom olika subkulturer. Företag kan med hjälp av symboliska värden sända ut signaler som stämmer överens med olika individers värderingar och på så sätt attrahera konsumenter och samtidigt ringa in en önskad målgrupp. Dock kan även det motsatta inträffa, det vill säga en annan grupp än den tänkta målgruppen kan komma att adoptera ett företags varumärke och göra detta till en del av gruppens image.Syfte: Syftet med denna studie är att identifiera och åskådliggöra hur en subkultur kan påverka det symboliska värdet av ett varumärke.Genomförande: För att uppnå syftet har det verkliga fenomenet hip-hopkulturens adoption av varumärket Adidas valts att empiriskt undersökas. Detta utifrån kvalitativa intervjuer gjorda med respondenter från hip-hopkulturen så som bland andra gruppen Latin Kings och Infinite Mass, tillsammans med personer från företaget Adidas, samt analyschefen på MTV Nordic Networks och radioproducenten Stefan Wermelin.Resultat: Denna undersökning visar bland annat på att en subkultur kan påverka det symboliska värdet på ett varumärke genom att inte enbart ta till sig de symboliska karaktärer varumärket står för, utan även överföra subkulturens värderingar på varumärkets image.

Within media and communications studies, questions of taste have often been associated with the dichotomy of high versus popular culture. The French sociologist Pierre Bourdieu has also used mass media products in his studies of class determined tastes and dispositions. In this paper the author uses the theoretical framwork of Bourdieu to examine aspects of social class and legitimate taste in the interior design magazine "Sköna Hem", a market leading magazine within it's genre of lifestyle magazines in Sweden. A specific type of feature article, where a real-life home is portrayed, is studied using the critical discourse analysis of Norman Fairclough. The homes portrayed are predominantly affluent and display elements of conspicuous consumtion as mediated through legitimate taste and cultural capital.

År 2008 var 43 miljoner barn under fem år diagnostiserade med fetma. Fetma anses som en kronisk/långvarig sjukdom och ett folkhälsoproblem med behov av förebyggande arbete för att förhindra framtida konsekvenser. För beräkning av kroppsfett används Body Mass index (BMI). BMI är det mått som används världen runt och räknas genom att dividera kroppsvikt i kilogram med längd i meter i kvadrat. Att ungdomarna drabbas av fetma beror främst på dåliga matvanor, obegränsad tillgång till kalorier i form av kolhydrater och fett ofta i kombination med mindre fysisk aktivitet.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

On July 22, 2011 a bomb detonated in the government building in central Oslo in Norway and eight persons died. Later that day, 69 people, most of them youths, were shot down and killed on the island of Utøya by a uniformed Norwegian man.The purpose of this study is to analyse Anders Behring Breivik's personality and explain why he became a killer. I have used a Psychobiographical narrative method, which serves to describe the mind of a human being, linking the mind to motives, scripts, unconscious ideas and personality.My primary sources are Breivik?s Manifest: 2083 A European Declaration of Independence and the inter-views with his father and stepfather, together with the Psychiatric Reports which were submitted to the District Court of Oslo. I have analysed in what way Breivik?s childhood influenced his behavior as an adult.
