The purpose of this paper is to find out which portfolio theory one should use during a financial crisis. We will examine two different portfolio theorys, the Minimum Variance portfolio and the beta portfolio.We have chosen to study two different portfolios, and followed their development during the financial crisis with its start in 2008 and the IT bubble with its start in the middle of 2000.The data has been collected from OMX internet database making it quantitative study. The beta portfolio's objective is to follow the index and the Minumim Variance portfolio´s objective is to spread the risk by investing in stocks with low volatility. By following the two different portfolios, and compare the development to the index, we will be able to determine which theory is most suitable to use during a recession. The studyperiods we chose were both in a recession and it turned out that the most appropriate portfolio to use was the Minimum Variance portfolio because stock in this portfolio tends to be less sensitive to economic fluctuations..

AbstractThe purpose of the study was to examine if manual signs used as support to spoken and written language can be a god mnemonic for learning of word-pictures. I performed my study as an experiment in which I made a Memory game with word-pictures. I played the game with the children twice. The first time, we played without manual signs and the second time I used sign as a support. I observed the children and noted the words they learned to read with and without the support of manual signs.

The term "Project" have become a growing work model that exist in almost all bransches. A project is a work effort made over a finite period of time with a start and a finish to create a unique product, service, or result. Science shows that time limitation has an impact on humans to perform under pressure, which challanges the contributor to deliver. This report contains an examination about project management, both coming from scientific results and an external business. The point of this study is to bring ideas of improvement, which can make the work method more effective in this company..

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure. The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Regionalization has become a catchphrase in European countries during the last twenty years with the establishment of the European Union. An ideational development has occurred during time towards emphasing more politicially powerful regions with the idea of new regionalism. Sweden represents a deviant case study, where regions historically have been politically weak and where Sweden has been characterized as a strong unitary state. The aim of this paper is to analyze the political debate in the Swedish parliament concerning the implementation of a stronger regional level (storregioner) during 2007-2010 and to determine if the debate can be characterized as a case of depoliticalization. The theory of depoliticalization have been introduced by Richard Katz and Peter Mair to explain why political parties through external pressure from europeanisation and globalization tend to become more consensual with similar political agendas, leading to a diminished the lef-right scale.

This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

In this essay I investigate how the Roman colonization (around 50 BC to 400 AD) affected the Celtic religion. I inquire which operators that were behind these changes and under what circumstances they happened. I take a closer look on three places in Gaul and one place and one area in Britain. In my study of these places I see that it was the elite of the Celtic societies who together and under pressure from Rome made these changes. The religion and gods did not change; instead the ritual ceremonies changed to fit into something that Rome thought was right.

Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
