As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

Bakgrund: Deep Brain Stimulation (DBS) i nucleus subthalamicus (STN) och i kaudala zona incerta (cZi) har visat positiva effekter på motoriska symtom (rörelseförmåga och balans) vid Parkinsons sjukdom. Efter DBS har dock negativa taleffekter noterats, inklusive nedsatt artikulatorisk precision och stabilitet. Nedsatt artikulatorisk precisionoch stabilitet påverkar klusilproduktionen mest vilket kan resultera i att klusilexplosionen uteblir eller att multipla explosioner uppstår.Mål: Att undersöka artikulatorisk precision och stabilitet vid klusilexplosionen efter DBS i STN respektive cZi.Metod: I studien deltog 19 patienter varav 9 deltagare stimulerats i STN och 10 deltagare i cZi. Talinspelningar gjordes innan operation och ett år efter operation med DBSstimulering på och av. Klusilerna i talmaterialet delades in i tre kategorier, de med en klusilexplosion, de med två eller flera klusilexplosioner samt de utan klusilexplosion.

In my degree project I have focused on how to make it easier for ambulance personnel to remove a motorcycle helmet after an accident. During my research I have interviewed ambulance personnel from different cities and a trauma surgeon to get a better understanding of how they work today and the problems they experience. Some of the problem areas are that you need a lot of force to remove the helmet, that the padding catches the ears and that the chin guard catches the face. Since ambulance personnel always assume that there is a neck injury after an accident, all these problems make it difficult to remove the helmet safely.The result is a motorcycle helmet with a focus on safe removal after an accident, to reduce the risk of worsening a neck injury. The solution suggested is that a small part of the back of the helmet is detachable, to make the opening larger.

The Swedish Armed Force has a need to streamline the preparation of an exercise in tactical training for soldiers because the preparation of an exercise is currently laborious and time consuming when commanders manually share files to each computer that will be included in the exercise. The degree project was to create a file sharing program within the internal network of the Defence Forces? international centre (Swedint). The program is used by the training management to effectively start up an exercise where soldiers train tactical training in a simulated combat environment. The training management use this program to upload files to a server which notifies all the computers on the network to download these files.

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

In Sweden prostitution is by many considered to be a social problem that primarily affects women. To counteract prostitution is a political priority and as a result the purchase of sexual services is prohibited by law. Since the law that prohibits the purchase of sexual services entered into force it has been continuously debated and widely disputed. The aim of this thesis is to compare the image of prostitution found in the travaux préparatoires of the law with four sex workers? view of the phenomenon.

Under en operation behöver patienter tillföras vätska. Det finns en pågående diskussion om vilken sorts vätsketillförsel som har fördelar för patienterna. Framförallt diskussionen om glukos ska tillföras eller inte. Förhöjda blodsockervärden under och efter operation har visat sig ha negativa konsekvenser för morbiditet, mortalitet och vårdtid. Det finns inga entydiga riktlinjer kring peroperativ vätsketillförsel.SyfteAtt se hur plasmaglukosvärdet hos patienter som tillfördes eller inte tillfördes glukosinfusion vid planerad kolorektal kirurgi förändrades över tid, per- och postoperativt, och hur detta påverkade diures och illamående de första fyra timmarna postoperativt.

En viktig del av en nations säkerhetspolitiska ambition handlar om att skaffa sig handlingsutrymme. Detta görs genomen orkestrering av nationens olika maktmedel. På militärstrategisk nivå skapar en samordning av politisk målsättning,doktriner och resurser en samlad nettoeffekt, vilken utgör nationens möjliga militära strategi.Efter att det kalla kriget upphört har stora förändringar i den säkerhetspolitiska miljön för bland annat Sverige ägtrum. Sverige har därför förändrat sin säkerhetspolitiska utformning och Försvarsmakten och dess luftstridskrafter harföljt efter. Det svenska flygsystemet skall idag exempelvis kunna användas i av NATO eller EU ledda fredsframtvingandeoperationer.

The Capturetheory wants to give an alternative explanation for the need of regulation. From this point if view the government does not have enough information to make an optimal regulation. There is a possibility for different interest groups to take advantage of the political arena by rent- seeking behaviour. An industry may be willing to be regulated to protect itself from competition. The objective of this paper is to account for the pros and cons of the theory of regulatory capture and also if it can be applied to the Swedish market of pharmaceuticals.

In the beginning of the 21st century, a number of scandals were pointed out in the US. Enterprises like WorldCom and Enron went into bankruptcy, and inaccuracies in their account were made public. This led to the fact that a new law, SOX 404, was established in the US. The law says in its whole that enterprises must have better control of their internal accounts.The aim with this paper is to examine how the surrounding world of an organization with stakeholders as well as other surrounding elements, affect or force an organization to change, and how a changing process is introduced and accomplished.We carried through a survey as well as interviews at the actual organization. Furthermore, we investigated why the change has come into practice as well as attitudes and opinions towards the change, and lastly, how the changing process has been accomplished.

This is a thesis about the American empire. I also focus my work to see if this American empire is declining. The two main questions I ask and want to answer in this thesis are: is America an empire and is it in decline?I first conclude that America has been an empire ever since the end of the Second World War. The sheer military and economic power of the American empire matches and exceeds the ones before them.

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

In this paper I have studied how feminist parents talk to their children about body and sexuality and with which intentions they speak the way they do. The aim of the study was to locate strategies applied to give children positive relations to their bodies and their sexuality. My data are constituted by answers from a questionnaire sent out to an e-mail list for feminist parents. The answers have been compiled and analyzed, mainly qualitatively by the use of discourse analysis, with support of poststructuralist theories about language, gender and heteronormativity, as well as theories about children?s sexuality.

Bakgrund: I Sverige opereras 24% av de extremt för tidigt födda barn (EPT) för öppetstående ductus arteriosus (PDA). EPT barn som behandlas med ductuskirurgi riskerar få i sig för lite energi och makronutrienter på grund av volymrestriktioner och rädsla för att påbörja enteral nutrition efter genomförd operation och därigenom utveckla nekrotiserande enterokolit (NEC). NEC är ett ischemiskt och inflammatoriskt tillstånd hos prematura barn i vilket delar av tarmen nekrotiseras (vävnadsdöd).Syfte: Att beskriva tillförsel av energi, makronutrienter och vätska inför, under och strax efter ductuskirurgi hos EPT barn.Metod: En svensk populationsbaserad kohortstudie av EPT barn födda mellan åren 2004-2007 och som opererats för PDA (n=140, 83 pojkar, genomsnittlig födelsevikt 723 g). Utförlig information avseende perioperativ nutrition inhämtades retrospektivt från sjukhusjournaler. Det dagliga intaget av enteral- och parenteral nutrition samt blodprodukter användes för beräkning av intaget av energi, makronutrienter och vätskevolymer tre dagar före fram till och med tre dagar efter operation.
