The purpose of this report is to study the risk of Dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning Dust explosions.

Dust, our smallest common denominator                                                                                                                                                                 Charlotta Lindvall ABSTRACT  I find it fascinating to know that we are all made of the same material as the stars and that everything is connected to each other and in a constant movement and transformation, a recycle of material. We are all made of stardust. In fact all life is sprung out of dust.In my essay I investigate the dust and ask the question if there are any traces in the dust. I look at the history of the dust and how it has affected us and our world through the decades. What does this small and airy but oh so unappreciated dust tell us? Why do we want to get rid of it? Is it possible to find a sense of belonging in the big context by investigating the dust and its origin and could I transform such a low material as dust into something magic that makes people reflect on our origin and belonging and how everything is connected? In my work I use dust as a material and in the essay I compare my work with other artists who have worked with dust as a material.Dust is everywhere because its source is from everything.

Dust that arises during the construction process is called ?construction dust?.People who are exposed for construction dust for a long period of time are atrisk to develop several forms of lung problems, allergies and cancer. Todayconstruction dust is a huge problem during the production in Skanska´srenovation projects. Every day workers are exposed of the unhealthyconstruction dust and it can cause lung problems and diseases after 10-30years. This is a problem that must be taken into account to obtain a betterworking environment on Skanska´s building sites.Skanska Sweden AB has given two students the task to investigate possibleproblems about the spreading of construction dust.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

In this thesis, I enquire into how the USA ? our world?s wealthiest and most powerful nation ?  and its federal government has dealt with two of its most severe natural disasters: the drought and dust storms that plagued the Great Plains during the 1930?s, i.e. the Dust Bowl, and Hurricane Katrina, which made landfall in late August 2005. I attempt to identify differences and similarities and analyze if and, in that case, how the hegemonic politico-economic paradigm affected the federal management of these crises. This comparison is made relevant by the fact that two differing paradigms were at play during these events. In the thirties, President Franklin D. Roosevelt launched his ?New Deal?, a series of counter cyclical measures in line with the Keynesian school of economics, as a response to the overwhelming economic depression as well as the raging drought.

In this report I will describe how an art-directed fluid effect for motion picture can be achieved. This effect will be an explosion with a visual style that is congruent with Pixar's movie Up. To begin with I will analyze the visual components that are used in Up and control the fluid simulation to get the desired visual style. I will briefly explain the background of my thesis, why it is interesting to create designed effects and why it is hard to design fluid effects. In the method I will explain my work process and some of the challenges that arises.

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Development of a vacuum cleaner nozzle for energy efficient dust pick-up.

The project ?Investment proposal for grinding station for service work of screw feeders? has been performed during the spring semester 2014 for the course Bachelor?s thesis for degree of  Bachelor of science in machine engineering at Karlstad?s University. The project has been performed in cooperation with Fiber Workshop which is a service department in the company Valmet AB. Valmet AB is a company that develops and manufacture soft paper tissue machines. The screw feeder is a part that is used to feed, and squeeze out the water out of woodchips.

This report consists of two parts, out of which the first deals with the planning and designing ofa small house in the Swedish city of Huddinge, using the weather conditions of the Swedish cityof Malmö. The house has to be in accordance with the Swedish building- and constructionregulations, as well as with the limitations in energy consumption given.The house itself has to consist of at least two bedrooms, and blueprints of the house, variousconstructional elements, ventilation, sanitation and electricity have to be drawn. Calculations ofthese aspects also have to be made, to ascertain that the different parts function as they should,and that the dimensions are sufficient.The second part is called ?Allergy free home?, and investigates how indoor climate affects us,and whether it has changed during the last few decades. It also makes an effort to see whetherthe increase of allergies and asthma is correlated with possible changes in indoor climate, andwhether technical solutions might help to handle or even decrease the issues arisen.

Bakgrund: Deep Brain Stimulation (DBS) i nucleus subthalamicus (STN) och i kaudala zona incerta (cZi) har visat positiva effekter på motoriska symtom (rörelseförmåga och balans) vid Parkinsons sjukdom. Efter DBS har dock negativa taleffekter noterats, inklusive nedsatt artikulatorisk precision och stabilitet. Nedsatt artikulatorisk precisionoch stabilitet påverkar klusilproduktionen mest vilket kan resultera i att klusilexplosionen uteblir eller att multipla explosioner uppstår.Mål: Att undersöka artikulatorisk precision och stabilitet vid klusilexplosionen efter DBS i STN respektive cZi.Metod: I studien deltog 19 patienter varav 9 deltagare stimulerats i STN och 10 deltagare i cZi. Talinspelningar gjordes innan operation och ett år efter operation med DBSstimulering på och av. Klusilerna i talmaterialet delades in i tre kategorier, de med en klusilexplosion, de med två eller flera klusilexplosioner samt de utan klusilexplosion.

I alla mjukvaruprojekt spelar mjukvarutestning en viktig roll. Om enprogramdefekt inte upptäcks och rättas innan systemet sätts i produk- tion, kan detta leda till betydande förluster för organisationen.Scanias kunder har möjligheten att skräddarsy sina fordon, efterkundens egna behov, istället för att välja bland en uppsättning färdigamodeller. Denna praktiskt taget oändliga uppsättning teoretiska model- ler medför dock svårigheter inom testning.En elektronisk styrenhet (ECU) är ett inbyggt system som kon- trollerar ett eller ?era av de elektroniska systemen i ett fordon, t.ex.motorn, kraftöverföringen och luftkonditioneringen. När fordonen läm- nar produktionen parametersätts deras ECU-parametrar efter ett regel- verk som anges i kon?gureringsprogrammet Parameter Setting Module(PSM).
