Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

Introduction and background: The 1990s crisis and the global financial crisis year 2008 shows the same indications that the property market was affected negative. The Swedish Property companies had a difficult time on the market when the crisis led to decreased property trade and financing problems for the Property companies. The Swedish property companies became less attractive on the market and contributed to a drop in prices on investment property.Purpose: The purpose of this essay is to examine if there is any relation between the Swedish Property companies impairments on their investment property and the global financial crisis year 2008.Method: The essay is based on a quantitative study where we examined Swedish Property companies? annual reports. We answered our questions and our purpose from the empirical data that we collected from the annual reports.Conclusions: The study resulted in that we found a correlation between the Swedish Property companies? impairments on their investment properties and the global financial crisis year 2008.

Within the ambulance care in Uppsala County a vacuum splint is used to immobilize fractures on extremities. The research available on which method of immobilizing to prefer during pre-hospital treatment is limited. The purpose of this pilot study was to examine the perceptions of the ambulance personal in Uppsala County on the issue of usability of SAM-splint and vacuum splint when immobilizing extremities. The project was also aimed at researching if SAM-splint could be seen as an alternative or a complement to vacuum splint, and to get an apprehension on any evident differences in patients? perceived pain when treated with the two different approaches. A descriptive comparative study was carried out. All patients, regardless of age and sex, with the need of immobilizing supposed fractures, were included.  Patients with suspected femur fracture, collum fracture, or where pre-hospital care was not possible or in question, was excluded.

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The paper examines how human inner properties and the interpretation of the external worldare explained and presented in Dark City (Alex Proyas, 1998). Aspects as the relationship between the body and soul/consciousness, body snatching, memory transferences and dystopian cities are analyzed. The field of study is compared to a general science-fiction film perspective regarding the aspects. Dark City contains an alien race with a common mind, but who lacks soul and individuality. They represent what humanity can become if the scientific development goes too far.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

This bachelor thesis covers fire protection methods of structural steel and the aim is to develop an information tool designed for inexperienced structural engineers. The information tool covers basic fire protection methods and the general way to produce a fire resistance for structural steel. The layout of this information tool is a simple folder that contains information about the most important steps when producing fire protection for a steel structure.The thesis starts with a general overview of the fire protection needed in buildings to fulfill national legislative and regulatory requirements. To get an understanding of how steel components behave during the influence of fire, a brief overview is presented of the material properties of steel. This chapter also contains a review of previous research in the area.

Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. The two most common methods of protection are corrosion protection paint and zinc coating. To determine the method, the corrosive category must first be evaluated and this is done in accordance to EN ISO 12944-2:1998.Stainless steel is available in many varieties but only some of them have properties that make them suitable for use as construction steels. There are many factors to be considered in the design of stainless steel to prevent corrosion from occurring.

Generally prosody is described as the rhythmic, dynamic and melodic features of language. Prosody is further often described as suprasegmental, since its properties go beyond vowels and consonants, which are segmental characteristics of language. A relationship between prosody and music has been noticed and described for several decades. At present, there are several studies proving relationship between prosodic and musical abilities. The aim of the present study was to construct a test for prosodic non-linguistic perception and production regarding intonation and rhythm. The test was tried out on 16 children with typical language development aged 4;6-7;6 years. Before testing of ITAP each participant were asked about musical experience.
