A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Fysisk aktivitet är en viktig friskfaktor och fysisk inaktivitet är en stor riskfaktor för ohälsa. Fysisk aktivitet innebär allt ifrån friluftsliv till styrketräning. God muskelstyrka är viktigt att ha under hela livet. Syfte: Syftet med denna studie var att jämföra fysiskt aktiva och fysiskt inaktiva kvinnliga ungdomars muskelstyrka och fysiskt aktiva och fysiskt inaktiva manliga ungdomars muskelstyrka. Metod: Fysiska styrketester genomfördes på övre och nedre extremitet samt bålen.

Detta examensarbete baserar sig på fyra frågeställningar och en hypotes kring hur den deduktiva grammatikundervisningen påverkar tyskelevers interlanguage. Undersökningen försöker visa om den deduktiva metoden t.ex. gynnar en viss elevgrupp beroende på etnicitet och genus. Undersökningen består av ett Grammaticality Judgement Test och en intervjuundersökning bland elever i grundskolans senare år skolår 8 och 9 som läser tyska som språkval. De grammatiska strukturerna som undersöks har eleverna redan blivit testade på vt 2008 i samband med den ordinarie tyskundervisningen.

The characteristics of free movement is the elimination of obstacles to trade between Member States and thus by such, create free movement within the entire union. Therefore art 34 in the Treaty of Lisabon (FEUF) states that all quantative restrictions on imports and measures of equivalent effect are prohibited. The legal approach to measures having equivalent effect is still unclear and the purpose of this paper is therefore to propose a solution to that particular problem. What can be said when it comes to this rule is that the EU-Court has gone from applying a discrimination test to a market access doctrine.According to the Court´s case law, measures having equivalent effects to quantative restrictions are ?All trading rules enacted by Member States which are capable of hindering, directly or indirectly, actually or potentially, intra-community trade?.  The question of how to apply the test when it comes to a potential hinder to intra-community trade is still unclear.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

The aim of this study is to investigate the effect of an intervention that focuses on phonics, decoding, reading speed and phonological awareness for 8-9 year old children in reading difficulties. Participants were selected on the basis of screening test results in grade one (decoding and reading comprehension). The participants were divided into two groups, an intervention group (A1, n=10 children) and a control group (A2, n=10). A1 received 30 minutes of intense reading instruction every day for six weeks from special educational needs teachers on top of their usual classroom based reading instruction. The control group received only their usual classroom-based reading instruction.

In Sweden the amount of people with obesity has increased with almost 50 % during the past 20 years and is now including 500 000 people. A larger energy intake than energy consumption is today one of the most important cause of overweight and obesity that exist in the world. This requires more knowledge about healthier eating habits combined with moderate intensive exercise, exercise that is simple, effective and amusing. A god solution is a combination of fitness training and strength training, a type of circuit training. It is distinguished by a high intensive work in short periods and with a short break.

Introduktion: HIV-infektion medför en kronisk och progressiv sjukdom som, i obehandlad form, leder till en successiv försämring av immunförsvaret och utvecklandet av AIDS.Syfte: Att vid två lärosäten undersöka sjuksköterskestudenters kunskaper om HIV och inställningen till behovet av HIV-testning.Metod: En empirisk tvärsnittsstudie med deskriptiv och komparativ design med kvantitativ ansats. Genomförd som enkätstudie bland studenter vid Högskolan i Gävle och Uppsala Universitet (N=95), som studerade på sjuksköterskeprogrammets tredje år. Resultat: Majoriteten (88,4 %) angav korrekt att samlag med fler än en partner ökar risken att smittas med HIV. Tre studenter (3,2 %) angav felaktigt att det finns ett vaccin mot HIV-infektion. Nästan hälften (42,1 %) saknade kunskap om att glidmedel, tillsammans med kondom, inte minskar risken för HIV-smitta.

The purpose of this study was to see how teachers experience their own leadership style and how they did to get their leadership to work in the classroom. The purpose was also to understand the teachers? actions, what they think is best for the students? development and how they describe the leadership in the classroom. I interviewed six female teachers and they all have had many experiences since this is their profession. My research was based on Stensmo (2000).

Juvenile criminality has been widely discussed in the public debate. But what is there to do about a phenomenon like juvenile criminality in Sweden. Many studies have shown the potential of lowering juvenile criminality if different actors would collaborate. This research aims to explore preventive work and cooperation between different actors working with youth in risk of crime in Angered, with a focus on Hjällbo and Hammarkullen. The study is based on social and situational theory.

Syftet med denna studie var att ta reda på om STAVUX (stavningstest för vuxna) och Kasttranskription är lämpliga test att använda vid dyslexiutredningar av vuxna, då det idag saknas sådana test som är normerade på personer över 18 år. STAVUX är ett stavningstest som framtogs av Nilsson och Pettersson (2009) och som består av 45 ord och 45 nonord av varierande svårighetsgrad. Orden är utvalda för att representera svenskans olika stavningskombinationer och nonorden är konstruerade för att följa svenskans ljudmässiga uppbyggnad. En mellangruppsdesign användes för att ta reda på om STAVUX är ett lämpligt test att använda vid utredning av stavningssvårigheter i samband med dyslexiutredningar. Testet validerades på 23 personer med dyslexi i åldrarna 18-64 år.

Tidigare forskning har visat att det finns ett samband mellan personlighetsdraget neuroticism och yttre motivation, a-motivation, låg självkänsla samt negativ affekt. Syftet med studien var att öka förståelsen för neuroticism som personlighetsdrag utifrån individernas motivationstyp, självkänsla samt individernas affektiva tillstånd. Studien undersökte även reliabiliteten hos instrumentet Mini-IPIP som har undersökt personlighetsdrag inom Big-five-teorin. Syftet testades med hjälp av fyra självskattningstester. Dessa var Mini-IPIP, Situational Motivation Scale (SIMS), Positive Affect and Negative Affect Scale (PANAS) samt Rosenbergs Self-esteem Scale (SES).

Sett utifrån ett historiskt perspektiv har utvecklingen av soldatens utrustning skett relativt långsamt. Dock har utvecklingen under det senaste decenniet gått fort framåt. I början på 2000-talet konfronterades flera länder av behovet av att utveckla soldaten och dennes personliga utrustning. Därför startade många länder egna framtida soldatsystemsprojekt. Tillgången till ett C4I-system är något som alla framtida soldatsystemsprojekt har gemensamt.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

?Medicines are available in different forms and often have different types of compound components. More and more drugs are found on the market. This means that professionals who handle different medicines must have access to more and more information.The information available includes information about side effects, active substances, interactions and pill identification. You may want to access different information, depending on your profession.
