Avgasrening för framtida miljökrav
SammanfattningI dagens miljöfokuserade samhälle ställs det allt högre krav på den tunga fordonsindustrin varvid den gällande miljölagstiftningen skärpts i flera steg de senaste åren. Scania tillverkar tyngre fordon och motorer som alla måste följa de kommande utsläppskraven. Detta innebär att motorernas utsläpp måste reduceras varför avancerade efterbehandlingssystem har införts i ljuddämparen. En metod för att rena avgaserna från kväveoxider är SCR-teknologi (Selective Catalytic Reduction). Denna teknik bygger på att en urealösning sprutas in i avgasflödet.
Plan för multifunktionella buffertzoner längs Vramsån på Malörten AB: s jordbruksfastigheter
To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.
As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.
Att tala om ansvar : om Levinas ansvarsbegrepp i gränslandet mellan det etiska Sägandet och det politiskt Sagda
The present essay concerns the Levinasian understanding of responsibility in relation to the two spheres that Levinas introduces in his second major work Otherwise than Being or Beyond Essence, namely the Saying and the Said. The essay investigates some of the different meanings that the concept responsibility takes on in regard to these two spheres, and thus also in regard to the separation between the ethical and the political that is apparent in the book. Is it possible to find a politically uttered responsibility in Levinas Otherwise than Being or Beyond Essence?The essay wants to emphasize the continuous transition between the ethical or the Saying and the political or the Said, and vice versa, with the purpose of showing how the two spheres may be conceived simultaneously. By posing the relationship between the two as a reciprocal rather than a oppositional one, the essay aims to suggest that an understanding of responsibility at once must be ethical and political.
Mindfulness verkan hos personer med kronisk smärta: En systematisk litteraturöversikt
Idag lever cirka 40-65% av Sveriges befolkning med kronisk smärta. Påverkan av kronisk smärta på en persons livsstil varierar, en del ser smärtan som en olägenhet i vardagen medan andra upplever att smärtan påverkar varje aspekt av livet. Det är inte lätt att behandla kronisk smärta då variationer på smärtan är många och diagnosen ofta är osäker. Alternativa metoder för att behandla smärta blir allt vanligare och en sådan metod är mindfulness. Syftet med studien var att beskriva den samlade kunskapen kring mindfulness verkan hos personer med kronisk smärta.
Förskollärares uppfattningar av ljudmiljöns påverkan på den pedagogiska verksamheten
Den pedagogiska verksamheten påverkas av ljudmiljön som antingen kan främja eller motverka kommunikationsmöjligheter. Då tidigare forskning genomfört objektiva mätningar efterlyses mer subjektiva studier, vilket denna studie syftar till. Syftet i denna studie är att undersöka hur de medverkande förskollärarna uppfattar att ljudmiljön påverkar den pedagogiska verksamheten. Studien ämnar även undersöka vad förskollärare uppfattar sig göra för att främja en god ljudmiljö. För att besvara syftet har följande frågeställningar använts:Hur uppfattar förskollärarna att ljudmiljön påverkar verksamheten?Vad uppfattar förskollärarna vara en god ljudmiljö?Hur uppfattar förskollärarna sig arbeta för att främja en god ljudmiljö?Den teoretiska utgångspunkten för studien är von Glasersfelds (1995; 2000) radikal konstruktivism och kvalitativa intervjuer har genomförts.
"Sist in - först ut" : Hur turordningsreglerna förhåller sig på den svenska arbetsmarknaden idag?
Abstract The subject of this thesis is the priority rules that apply in connection with mining activity. Already back in the 1800s, there were rules in the so-called Lego Charter concerning protection of workers, mainly servants. When the first modern trade union was founded in the 1870s, also developed a collective agreement. These agreements were the order of priority clauses had to intend to ensure employees' working lives. Exceptions had to be done by ensuring that individual employees' dependents. In 1974 the Act on employment entry and had intended to protect older workers.
Läsförmåga hos barn med Cochleaimplantat : Relaterat till kognitiva och språkliga förmågor
Cochleaimplantat (CI) är ett tekniskt hörselhjälpmedel som används av personer med grav hörselnedsättning eller dövhet. Ett CI ger barn med medfödd dövhet möjlighet att höra och utveckla talad kommunikation. CI ersätter inte normal hörsel och det finns stora individuella variationer i språk och talfärdighet hos personer med CI. Syftet med föreliggande studie var att studera kognitiva och språkliga förmågor hos barn med CI med fokus på läsförmåga. I studien deltog 57 barn i åldrarna 7;3-10;4 år.
Minnesallokering och debugverktyg
The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

Härliga hagar och skrämmande skogar : om våra känslor för landskapet och vad de beror på
Do our imaginations of real landscapes get affected by works of art such as paintings, myths and literature? They often give very colourful descriptions in words as well as pictures. Do they actually change our feelings for the landscapes we are in and carry around as images inside?
Close your eyes and take a few deep breaths. Imagine that you are leaning against a wooden fence a mild summer evening.
Fenomenofonen : En undersökning om ljud på webben
Ljud har en förmåga att påverka våra känslor. Begreppet ljudwebb är framtaget till denna undersökning och syftar på de ljudlagda applikationer som, i och med den tekniska utvecklingen, har börjat dyka upp inom webben. Ljudwebben har fått sitt namn från ljudfilmen, de filmer som började experimentera med ljud under filmindustrins tekniska revolution runt 1930-talet. Syftet med denna undersökning är att utforska vad ljudets känslopåverkande egenskaper kan bidra med inom webben. Genom att utgå från fysiker-filosofen Karen Barads tankar om det ständigt rekonstruerande fenomenet samt filosofen Sarah Ahmeds kritik mot den fenomenologiska orienteringen lyder undersökningens frågeställning.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.
Ekonomiskt bist?nd och brottslighet i Sverige
This study examines the connection between Sweden`s crime rate and financial aid, focusing on the effects of social spending on different types of criminal activity in the Swedish municipalities between 2000 and 2022. Using theories such as social support theory and utility maximization, the study investigates the relationship between economic assistance and crimes like theft, attempted murder, drug offenses, and assault. The results suggest a complicated relationship: financial aid is associated with a rise in drug offenses and assaults but a decrease in larceny and robberies, when controlling for all observed and unobserved time invariant factors in the municipal factors (a fixed effects panel data model). However, when we test our model for robustness, the effects disappear meaning that other factors that are time varying in the municipality are biasing our estimates. Examples for this may be factors like peer pressure, substance addiction, and socioeconomic conditions that have a considerable impact on criminal conduct, financial aid alone may not be adequate to curb crime.
Identifiering av slöserier på Lundbergs Plåt AB
Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.
Glaset i Centrum : En fallstudie på New Wave Group
Seen in many trends and studies, consumers of today feel a growing desire to experience the uniqueness in products and services. This is forcing companies be more innovative and creative in their marketing, in order to distinguish and differentiate themselves and their products/services. We believe that creating a top-to-bottom experience strategy is one way that a company can succeed in this.The purpose of this thesis is to analyze and clarify how a business can reinforce their product experience through a complete experience strategy. In order to demonstrate this we have made a case-study research for the New Wave Group, advising them on how they can place blown glass art at the heart of the town of Kosta.The authors have used qualitative methods and an abductive approach. Four interviews have been completed with executives from the New Wave Group, including the project manager, hotel manager, head of the Kosta Boda smeltery and head of guides and visitors at Kosta museum.
