Varför sviktar elevers intresse för matematiki de högre åldrarna? : Vilka faktorer ger elever motivationoch lust att lära matematik?

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Hur bemöts Kina i Afrika? : En mångdimensionell idealtypsanalys av Sydafrikas, Zambias och Zimbabwes bemötande av Kinas ökande ekonomiska intresse

The outset of this study is to contribute to the literature concerning China?s increasing economic interest to engage in the African context, its economies and resource abundandce. The overarching research problem is that the approaches held by the respective African state entities may facilitate increasing development gains for the recipient state of this economic interest in principle. To adress this research problem the study is undertaken by conducting a comparative case study where three cases/states, with presumably diverging economic and political status, are likely to effect their overall state approaches differently.Research questions, which are addressed by the creation of an idealtype analytic matrix, concern whether the states of South Africa, Zambia and Zimbabwe take on a more ?permissive? or ?restrictive? approach towards China?s economic interst and whether the approaches can be looked upon on both aggratege and case/area-specific levels.The main findings are that a clear tendency of the ?permissive approach? may be noted on a aggregate level for all cases.

Rostfritt stål som ett alternativt material till koppar i tappvattenledningar för bostäder

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Odefinierade platser i staden : med studie i Söderälje

The purpose of this master thesis is to attract attention to the undefined spaces of our urban landscape and emphasize the need of these spaces in the city. The different values of these spaces are here clearly presented so that they can be considered when real estate developers show a particular interest in any one of these undefined spaces. The term undefinied spaces can mean a lot of things. The spaces that I now choose to define as undefined spaces are neither planned nor designed. It could for instance be a piece of leftover land in between two residential areas, or as times change, a formerly planned area might be forgotten and left to its own.

Det situationsanpassade ledarskapet

The Swedish Armed Force is one of the largest authorities in Sweden and has as its primary mission to be responsible for Sweden's military defence. Their unique activity - to participate in armed combat ? requires leaders who can make quick and rational decisions in uncertain and conflicted environments. This study aims to gain an understanding of how individuals with leadership roles in the Swedish Armed Forces are experiencing their leadership in relation to the organization's structure and culture. In order to achieve the purpose of the study, the following research question was created: How do individuals with leadership roles experience the influences of the organization's structure and culture on their formal leadership? The theoretical starting point is Weber's organization theory, Schein's organizational culture theory, and different definitions of leadership.

Formulering och provning av en ny typ av sågkedjeolja

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Beräkning av värmeenergiförluster i flerbostadshus genom analys av den totala fjärrvärmeenergianvändningen :

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

Hälsoekonomiska utvärderingar - En litteraturöversikt om använding av konstnadseffektivitetsanalys inom folkhälsoområdet

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Manlighet i mellanstadiet : En kvalitativ studie om maskulina ideal bland pojkar i mellanstadiet

The aim of this study has been to examine, describe and analyze how masculinities can be represented and understood among boys in a Swedish primary school context. The study was conducted within a school located in a small community on the country side. Through the use of a qualitative research design we interviewed 13 boys from the fifth grade of this school, who all got to express and reason their perspectives of what it meant to them to be a boy in primary school and how that could impact their social life. For a wider understanding of the different dimensions of masculinity we used R.W. Connell's (2008) theoretical framework, hegemonic masculinity, which implies that there are multiple definitions of masculinities that are constructed in relation to each other in a hierarchical order.
