Föränderlig sittmöbel - att trolla fram en extra plats

The purpose of my project was to explore variability. I wanted to combine different ways of sitting and create some kind of seating furniture that could be changed to fit different kinds of situations and needs. I sought after a way to express safety and stability in the seating furniture and at the same time make it clear that it could be changed into something else or something more. It was very important to me that the furniture piece would have a long lifetime and would be something you kept for a long period of time. I decided that the changeable factor in my piece would be the possibility to change it from being a chair for one person into being a bench for two people.

En jämförelse mellan markbundna resistivitetsmätningar och helikopterburen Sky-TEM i Skåne

Tillgången till tjänligt grundvatten kan på vissa platser vara begränsad. Sveriges Geologiska Undersökning (SGU) har för första gången i Sverige använt sig av Sky-TEM (Danskt utvecklat system för mätningar med Transient Elektromagnetism från helikopter) i ett område i Skåne för att mäta resistiviteten i marken och på så sätt identifiera partier med salt grundvatten. Detta examensarbeta har haft sin grund i jämförelse mellan dessa Sky-TEM mätningar och egenutförda markbundna geoelektriska mätningar (elektrisk resistivitetsmätning med multielektrodsystem) De markbundna geoelektriska mätningarna genomfördes längs två profiler inom området för Sky-TEM mätningarna. Den ena profilen (Annero) i ett område där djupet ner till det salta grundvattnet tolkats vara stort, och den andra (Lillevång) i ett område där djupet hade tolkats vara litet.Tolkningarna från Sky-TEM och de geoelektriska mätningarna stämmer inte heltöverens med varandra. De visar båda på ett större djup till det salta grundvattnet vid Annero och ett mindre djup vid Lillevång, men också systematiskt på ett större djup vid mätningar gjorda med Sky-TEM jämfört med de geoelektriska.

Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes

A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

Effekten av sex veckors coreträning enligt det förkoreograferade programmet Fokus

Core strength is important in order to be able to do all types of daily activities. One way to exercise ones core muscles is according to the pre- choreographed program Fokus. Previous studies have shown that core training gives better balance and stability in the core and also improved techniques, body awareness and control. Aim: To evaluate the core endurance strength, the balance and the studied individuals self estimated body awareness and control after six weeks of training according the pre- choreographed program Fokus. Methods: A total of 14 people volunteered to participate in the study, six of which completed the study.

Yoga och isometrisk uthållighet i bål : Yogautövningens påverkan på den fysiska och mentala allmänhälsan

Abstract The core is the center of gravity in our body. Injuries and overload in the joints, is the most common reason for not be able to work in Sweden today. A god strength capacity in the core is important for secure and effective movements, as well for active athletes, as for non athletes. The increased number of employees, who report in sick today, has been correlated with psychological bad health. New methods to deal with mental and physical health problems among people can indicate to the fact that Yoga in the western world has increased its members, due its spiritual and physical recognition in favor of well being.

Media och näringslivet: En studie om hur mediedrev bör hanteras enligt informationschefer och presschefer

Media has power and impact. It is therefore important for managers to be able to handle media storms when they arise. If not, the brand can be affected negatively. It is managers who should learn to handle media storms because the managers constitute an important part of the external face of the company. Because it is managers who should learn to handle media storms it is interesting to study how media storms should be handled from a theoretical management-perspective.

Preaching to the choir? A Comparison of Fiscal Forecasts by Governments, Fiscal Policy Councils and the European Commission in the European Semester Framework

The high debt levels experienced in European Countries have lead to academic interest in the deficit bias -the tendency for governments to run budget deficits and accumulate debt. In part one of this thesis a surveyof the economic literature on the origins and solutions to the deficit bias are conducted. The proposedinstitutional solution to the deficit bias in the form of Fiscal Policy Councils (FPC) are outlined and existingEuropean FPCs presented. Based on the works of Calmfors and Wren-Lewis (2011) the EuropeanCommission (EC) is defined as an FPC. Based on this survey, two hypothesis are formulated: (1) theforecasts of future macro-economic events and fiscal performance will differ between the national FPCs andthe national government.

Analys av spänningsstabilitetsberäkningar i det svenska elsystemet

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

Personbilar i singelolyckor med dödlig utgång på Sveriges vägnät : Orsaker till olyckor och rekommendationer om hur dessa kan förebyggas

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

Kunskapssyn och lärande i estetiska lärprocesser och waldorpedagogik

My main purpose with this paper of John Steinbecks Of mice and men is to both analyze the long-lived structures and the unique individual destinies of the novel. I employ the method of the historical Annales-movement and use three divided levels in my analysis to try to capture these high structures and low moments of humanity in Structure, Konjuncture and the Individuality. The first level, Structure, is used to see how long-lived almost invisible geographic structures set the human act of condition. The second level, Konjuncture, is easier to grasp in understanding of time and embraces for example economic structures as the industrialism. The last level of Individuality is the fastest in time and easiest to understand but in the long run also the least important.

Finanskrisens påverkan på bilbranschen under hög- och lågkonjunktur : en studie av hur bilbolagen påverkats av den globala finanskrisen

Purpose:  The purpose of this thesis is to examine how the major car companies have been affected by the global financial crisis. We would also want to look at how revenues and profits have been affected, and what the consequences have been both within the company and the market in general. It?s also interesting to see how profitability and financial stability has been affected. We had chosen to do a ?before-after? comparison, and we chose to compare the years 2007 and 2009.Boundaries: We have chosen to concentrate on a corporation in the Asian market, more specifically Toyota.

Finansinspektionens varningssystem avseende försäkringsbolag : I teori och praktik

The financial sector includes insurance business, which is a crucial part of the infrastructure in a modern economy. There are different parts to protect within the financial sector which is the reason for a comprehensive inspection. History shows several examples of disasters a mismanaged financial sector can bring. This also affects the society and stability over all. The inspection is conducted by the Swedish inspection of finance, which ensures that the insurance companies follow the law for its practice.

Inflammatory cytokines induced by Bovine Viral Diarrhoea Virus (BVDV) in Peripheral Blood Mononuclear Cell (PBMC) subsets

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.
