Avgränsning av tillrinningsområden till grundvattenmagasin : vilken information ger berggrundens överyta?

Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.

Rotningsstimulerande effekt och kemisk analys av vattenbaserad extraktion av vedartade och örtartade skott av Salix smithiana Willd. :

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

Hur arbetet inom socialtjänsten har förändrats efter lagändringen, där barn som bevittnat våld fått brottsofferstatus och rätt till stöd och hjälp

Att behärska två språk och två länders syn på pedagogik är en bra förutsättning om man vill undersöka och jämföra dessa två länders syn på barn med funktionsnedsättning. Syftet med föreliggande uppsats är därmed att belysa hur skolans styrdokument i Sverige och i Ungern formulerar och beskriver barn med funktionsnedsättning. En del av syftet är också att finna likheter och skillnader mellan det svenska och det ungerska styrdokumentet.Som material till ändamålet används den nya svenska Skollagen (2010) och den ungerska Utbildningslagen (1993). Analysen genomfördes med analysverktyget diskursanalys där jag har analyserat språket som beskriver barn med funktionsnedsättning.Resultaten visar att båda skollagarna har en tydlig koppling till de gällande internationella dokumenten där allas lika värde poängteras. Den svenska Skollagen har dessutom en relationell och deltagande syn på funktionsnedsättning medan den ungerska Utbildningslagen, som är 17 år äldre än den svenska lagen, betonar en kompensatorisk och individinriktad syn..

Metoder för lastprioritering i fjärrvärmecentraler

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

Studie på beteendeförändringar hos katt efter behandling av Feline Odontoclastic Resorptive Lesion (FORL) :

Feline odontoclastic resorptive lesion (FORL) is a tooth disease affecting both domestic and wild cats. Although FORL was described as early as the 1920´s, the etiology is still unclear. Several hypotheses have been presented but different studies have obtained contradictory results, and today there is no generally accepted etiology. Teeth affected by FORL are characterized by root resorption with progressive destruction of the tooth structure and alveolar bone as a consequence of clast cell activity. The disease is considered very painful when reaching a certain stage.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Implementation & utvärdering av spelmotor i WebGL

This report describes an analysis of WebGL together with JavaScript with the aim to examine its limitations, strengths and weaknesses. This analysis was performed by building a 2D game engine containing some dynamic elements such as water, smoke, fire, light, and more. Different algorithms have been tested and analyzed to provide a clearer picture of how these work together. The report will go through the most basic functions of the game engine and describe briefly how these work.The result shows that JavaScript with WebGL can be considered to be a potent toolsets, despite the difficulties caused by JavaScript.In summary, similar projects can be recommended as Javascript and WebGL proved both fun and incredibly rewarding to work with..

OS i Kina, oberoende idrott eller politisk propaganda? : A Study of the Chinese Regime?s Political involvement, in the Beijing 2008 Olympic Games

The aim of this paper is to describe which view the Chinese government in connection with the Olympics wants to display for the natural world and analyze if this view coincide with China?s foreign-policy goals. A qualitative content analysis is used. By using the theory of rational choice and a model with three different political approaches I want to examine whether or not the foreign-policy goals of the Chinese regime comport with the view that displays in two major newspapers in China. Since the runoff voting in Moscow in 2001 for the 2008 Olympics the Chinese government has been able to act rational and to compose different strategies to use the Games in Beijing for political propaganda.

Mötet mellan misshandlade kvinnor och vårdpersonal : En litteraturstudie

Men abuse women every day. It has become a Health Problem which we affects all of us. Help is available for those women who have the strength to seek it. Health care personnel are often these women?s only contact with the surrounding world.

Utvärdering av en väggkonstruktion utan PE-folie : Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

Positivister och konstruktivister på partnerrelaterat våld i relation till könsmaktsordning: En meta-analys på forskning om dysfunktioner i militära familjer ur två vetenskapliga perspektiv

Denna C-uppsats är en meta-analys som granskar 20 vetenskapliga artiklar om partnerrelaterat våld, grymheter i krig och könsmaktsordningar i militära familjer. Alla studier är publicerade mellan 1978 och 2011 och behandlar våld i parrelationer, grymheter som begåtts av både manliga och kvinnliga soldater och kausala samband mellan krig, militarism och det civila samhället. Mitt mål är att testa teorin som säger att krig beror på patriarkala köns-strukturer som konstruerar stereotypa maskuliniteter och femininiteter, vilka i sin tur definierar män som starka, aggressiva och känslolösa, medan kvinnor antas vara svaga, sårbara, och vårdande. Genom att undersöka och jämföra variabler i både positivistisk och konstruktivistisk forskning, söker jag likheter och skillnader som kan ge en vidare förståelse för hur detta fenomen är sammansatt..

Kraftspelsanalys av transportstag : Prefabricerade väggelement i betong

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.
