The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

Uppsatsens syfte var att genom en kvalitativ undersökning utröna ensamkommande barns förväntningar före flykten, deras tankar om språk, språkinlärning och huruvida dessa förväntningar uppfylls eller förändras efter permanent uppehållstillstånd i Sverige samt om tankarna om språk förändrats. De sex pojkar som intervjuas i studien kommer från Afghanistan, Somalia och Kamerun och hade olika livserfarenheter innan flykten. Uppsatsen visar att förväntningarna förändrades i och med det faktum att de fick lov att börja skolan när de kommit till Sverige något som de inte hade kunnat föreställa sig. Några informanter, vilka var analfabeter, har även fått en för dem helt ny identitet i den bemärkelsen att de nu mera ser sig själva som läsande och skrivande människor vilket de inte hade kunnat föreställa sig tidigare. De som inte gått i skolan tidigare i sina hemländer och inte kan något annat språk än sitt modersmål tycker att det är besvärligt att lära sig svenska, det känns märkligt i munnen att uttala ord och meningar på svenska.

Syftet med uppsatsen är att undersöka den diskurs som följde i svensk media efter migrationsverkets beslut att ge syriska flyktingar permanent uppehållstillstånd.Metoden som vi har utgått ifrån är kritisk diskursanalys och innehållsanalys. Som data har vi valt ut tolv artiklar och två TV-program.Resultatet visar att media äger den makt som gör att de får avgöra hur ett sådant beslut ska presenteras och diskuteras. Resultatet visar även att media använder idag en annorlunda diskurs jämfört med 1980 och 1990 talet.Media kan med sin makt avgöra vem som ska/inte ska uttrycka sig. En ?Vi? och ?De? skapas av media som skiljer mellan den etablerade och den oetablerade i samhället.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.

Syfte: Att en kost rik p? m?ttat fett har en negativ inverkan p? blodlipider har l?nge varit klarlagt. D?remot r?der delade ?sikter om effekterna av kolesterolintag p? lipidniv?er hos personer med blodlipidrubbningar. M?nga kolesterolrika livsmedel inneh?ller ocks? en stor andel m?ttat fett.

Background: Because of the high unhealthy rates among women in the com-mune a project to reduce it have begun. For this reason we have been given the mission from the commune of Sotenäs to study the character of these women's health. Objective: To study the health among permanent employed women in the commune of Sotenäs. Method: Quantitative method. The data have been collected through question-naire survey.

According to the Employment Protection Act, the permanent employment is the main condition of employment in Sweden. Nevertheless, nowadays a large number of employers choose to apply other conditions of employment than the permanent employment in their businesses. The rapid technical development and the demands for shorter perspective investment in companies on the Swedish labour market have started the requirement for a more flexible workforce. On-call employment is one of the conditions of employment that is increasing the most. This condition of employment is adjusted by the parties on the labour market.

In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

Hälsosamma kostvanor och regelbunden fysisk aktivitet har visat sig vara viktiga beståndsdelar i förebyggandet och behandlingen av flertalet sjukdomar. Människors uppfattningar har visat sig vara av vikt i förändringen mot en mer hälsosam livsstil. Syftet med studien är att kartlägga uppfattningar bland vuxna invånare i Göteborgs kommun, med avseende på kost- respektive motionsvanornas betydelse för såväl den personliga risken, som allmänhetens risk att drabbas av sju livsstilsrelaterade sjukdomstillstånd. Enkäter valdes som forskningsmetod i syfte att samla in kvantitativa data från 180 individer i tre av Göteborgs kommuns tio stadsdelar. Resultaten visade att tron på livsstilens inverkan på sjukdomsriskerna, generellt sett, var stor men varierade beroende på sjukdomstillstånd.

The Employment Protection Act (1982:80; LAS) is one of the cornerstones of the labour law that regulates the relationship between employer and employee. The central rule as stated in 4 § LAS is valid for an indefinite term. LAS is a semi-optional law in accordance with 2 § LAS which facilitates deviation from the central rule.Temporary employment is dealt with in 5 and 6 §§ LAS, regulations and collective bargaining agreements. The purpose of the legislative change on July 12007 was to simplify the use of temporary employment and to make the law more predictable and easier to interpret. The previous law was unnecessarily difficult for the employer to know when to put into practice.
