Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation.

As changes occur more frequently in IT- and software development, it is important for the companies to meet the demands and needs of its customer. The companies have to be able to adapt themselves continuously in order till fulfill its customers changing needs in an effective way, which results in big changes of the companies? structures. The more traditional way of working is often replaced with more alternative approaches as a response to the reputable deficiencies of its predecessors. As an effect of the rapid change and development some companies now see big potential in switching to more Agile and flexible methods and some companies have no choice but to change their way of working.

In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

This literature review examines different forages which are well suited for suckle cow production in Sweden today. They should also be possible to cultivate in Sweden under the current circumstances. Crops suitable for grazing in Swedish climate but not used in Sweden today, but which may be relevant for Swedish conditions are also mentioned. In Sweden today, mainly grass silage, straw and hay are used as forage, but also wholecrop silage is used to some extent. However, concentrates are not used to a greater extent, since it contains too much energy.

Sweden introduced a development assistance policy in 1952 and thirteen years later Sida, Swedish International Development Cooperation Agency started, in 1965. But in 1995, five separate development assistance authorities came together and established the new Sida as it is today. Sida is Sweden?s representative in the development assistance policy field and they work through projects that have to be presented through a Country Strategy Process (CSP). The aim of this paper is to point out Sida?s perspective on the conducted development assistance policy and what guide lines that are followed.

This study is qualitative and will show what?s causing anxiety in a class. Further it will describe how teacher?s act and how they handle when anxiety becomes a problem in the education. How can one as a teacher handle and act in to these disturbing situations? The children, who are anxious, take important time from those students who really need help in their learning.

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.

This master?s thesis was written on the behalf of Saba Frukt och Grönt AB inHelsingborg and is the final part of the Master program in MechanicalEngineering at Halmstad University.The main task was to introduce visual control and increase the rate of concept intwo of the departments of the company. The goal is to come up withimplementation proposals, and if possible to implement one in the near future.The author attacks the problem by using the Six Sigma DMAIC-methodology as itis a clear and structured approach. As a complement Lean-inspired tools are used.After compiling the results from the interviews and benchmarking somesuggestions are made. These are reviewed with stakeholders and a discussion ofhow to go on further was held.

New tools for the assessment of aphasia are important for bothclinical work and research. To see how they relate to already existing testscan increase their usefulness. Western Aphasia Battery ? Revised was translatedto Swedish and compared with the Swedish aphasia test A-ning, partlyto compare content and partly to see how sixteen people aged between 22and 92 with aphasia performed on the tests. The subtests did not correspondcompletely and the type of items included varied a lot.

A high degree of urbanization with growing cities has raised a need of transforming closed landfill sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden. The case study is analyzed in the light of former studies regarding re-use of degraded urban areas, so called brownfields, and in particular studies and reports of landfill re-use. The result indicates that old landfill sites is identified as an area with possible values if transformed properly, in the case study area especially as green structure and recreation areas.

This is a qualitative case study of young womens? experiences of blogging about One Direction on the social media/microblogging platform Tumblr. The aim of this study was to find out what fan blogging is and why fans blog. We did this by creating an account on Tumblr where we invited young women between the ages of 16?29, who had active fan blogs dedicated to One Direction, to answer an open-ended questionnaire.

Hundreds of thousands of piglets are castrated without anesthesia in Sweden every year so that we may be guaranteed meat without boar odor. The smell appears while cooking meat of boar and is described as urine- and sweat-like. High levels of androstenone and skatole are considered the main factors behind boar odor. Skatole is a metabolite of the amino acid tryptophan, which is formed in the colon of all pigs. Androstenone is a steroid hormone that is released from the Leydig cells in the testes of boars.

The main purpose of this study was to examine how social work can be performed online, by a case study of Korrespondensgymnasiet that pursues distance education. The intention was to determine the possibilities and limits with the online communication between the school counsellor and the pupils. The study was based on qualitative semi-structured interviews with one school counsellor and five pupils and document analysis of three descriptions of the school counsellor?s profession. The theory that has been used in this study is the communication theory: Shannon and Weaver?s Model of Communication and non-verbal communication.

This is a study of the way power relationships change when women start to play candombe in Montevideo, Uruguay. Candombe is a type of music, which is traditionally played by men within the black minority in the country. This study has been done with an intersectional point of view, taking the social categories gender, class and ethnicity in account. The method used was participatory observation in a field study made in Montevideo between November 2008 and February 2009.This study?s main conclusions are that the power relationships change with the participation of women in candombe in several important ways: The women legitimize an alternative way to be a woman when they take the men?s role as a drum player.
