This technical report describes the master thesis in material engineering called ?Testing of surfaced hardened materials conceivable for gears and shafts?. The work extents 20 academic points. Land systems Hägglunds manufactures and sells different kinds of combat vehicles and terrain vehicles. Since the demands for bigger and stronger vehicles increases all the time, so are the demands on shafts, gears and other transmission details.

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

The absence of female directors on Swedish corporate boards is currently a hot topic for both politicians and business leaders all over the world. This thesis aims to discuss reasons for the scarcity of women on boards in Swedish publicly listed companies as well as what actions are taken to alter the composition of these boards. A rigorous selection of gender theories have been used together with data collected from in-depth interviews with mainly board members and nomination committees. Extensive analysis has led to findings that historical perceptions of differences between men and women linger as of today, which prevents women to reach top executive levels as well as board positions. The increasing use of headhunters has encouraged companies to look beyond male-dominated networks in an attempt to widen the range of potential board nominees.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

Studien använder ett explicit test och jämför ungdomar (14-16 år) och vuxna gällande deras riskbedömning av brott, attityder kring brott och moralnivå. Dessa faktorer förväntas ha ett samband med varandra och kan ge en förklaring till varför ungdomar begår fler brott per capita än vuxna (Ahlberg, 1996). Samplet som utgjorde ungdomsgruppen (N=101) togs från fyra högstadier och vuxensamplet (N=101) bestod av studerande vid Komvux. Testet var ett egenkonstruerat frågeformulär och visade på flera signifikanta skillnader mellan vuxengruppen och ungdomsgruppen där vuxengruppen rapporterade högre riskbedömning, strängare attityder kring brott samt en generellt högre moralnivå. Studiens resultat stödjer tidigare forskning som visat på en diskrepans mellan ungdomars och vuxnas riskbedömning.

Den 1 januari 2005 trädde IASB: s redovisningsstandarder i kraft. Dessa standarder skall tillämpas av alla svenska börsnoterade koncerner. En stor förändring, i förhållande till svensk redovisningspraxis, som dessa regler förde med sig var värderingen och redovisningen av goodwill. Tidigare ansågs goodwill som en restpost som inte behövde motiveras i någon större utsträckning. IASB har sett till att skapa en mer konkret syn på goodwillvärdet.

Syfte och frågeställningarHuvudsyftet med denna studie var att se om ett vertikalhopp eller ett trippelhopp uppvisade större känslighet att identifiera skillnader mellan opererat och icke-opererat ben i jämförelse med ett horisontalhopp hos individer som genomgått främre korsbands(ACL)-rekonstruktion.Studien syftade även till att undersöka om individens kön påverkade resultatet och om prestationen på de olika hoppen hade ett samband med isokinetisk benstyrka respektive det knäspecifika instrumentet KOOS, The Knee injury and Osteoarthritis Outcome Score.Metod17 försökspersoner, 9 män och 8 kvinnor (medelålder 28 år) deltog i studien. De hade alla genomgått primär unilateral ACL-rekonstruktion i genomsnitt 7 månader tidigare. Vid ett och samma mättillfälle utfördes ett isokinetiskt styrketest samt tre funktionella hopp: vertikalhopp (?Jump and Reach?), trippelhopp samt horisontalhopp. KOOS fylldes i av försökspersonerna runt samma tidpunkt (nätbaserat frågeformulär för utvärdering av patientens upplevelse av sitt knä och knärelaterade besvär).ResultatVertikalhoppet uppvisade en högre sensitivitet i jämförelse med horisontalhoppet vid test 7 månader efter ACL-rekonstruktion.Gällande de absoluta värdena (opererat ben) uppvisade både vertikalhoppet som trippelhoppet ett statistiskt samband med explosiv quadricepsstyrka (240grader/sekund), r=0,75 respektive r=0,73.Inget samband kunde ses mellan hopp och resultatet på KOOS.Inga könsskillnader hittades.SlutsatsResultaten visar att vertikalhoppet är ett mer sensitivt test för att identifiera funktionella nedsättningar i ACL-rekonstruerat knä i jämförelse med horisontalhoppet som ofta används som ?gold standard? i forskning och i den kliniska vardagen.En enkel och billig testmetod för vertikalhoppet, ?Jump and Reach? som användes i denna studie visar liknande resultat på sensitiviteten i jämförelse med datoriserade mätmetoder som är dyra och ofta inte tillgängliga i sjukgymnastens kliniska vardag..

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

Tal är det akustiska resultatet av rörelser i talapparaten med avsikt att förmedla ett språkligt budskap (Kent, 2000). Oralmotorisk funktion är en grundläggande förutsättning för talkommunikation (Sjögreen & Lohmander, 2008). Om tal- eller oralmotoriska problem uppstår kan en tal- eller oralmotorisk diagnos ställs utifrån en utredning över dessa funktioner (McAllister, 2008). Nordiskt Orofacialt Test ? Screening (NOT-S) är ett screeningmaterial som testar den oro-faciala funktionen (Bakke, Bergendal, McAllister, Sjögreen & Åsten, 2007).

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

The purpose with this final assignment is to find out how the old and the new regulations about Goodwill affect the Swedish companies, how their results and value of Goodwill changed since the regulation from IFRS took place. We will attempt to find out if the companies are better of with a yearly write-off or an impairment test every year to see if a write-down is necessary..

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

The purpose of this thesis is to give an understanding of how grocery stores relate to local foods. Through a case study representatives for two groceries in Norrbotten have been interviewed regarding why they supply local foods, how they try to influence customers to buy this, and how they decide upon the assortment of local foods. The result shows that groceries supply local foods in order to supply a wide range of products and to mediate social responsibility, in order to create customer loyalty. Concerning how the groceries try to influence customers to buy local foods the result cannot give any clear-cut view. Instead it shows that a grocery that actively works to influence customers to buy local foods markets them in specific ways, while the opposite applies to a grocery that does not actively work for this.

The purpose of this master thesis is to create, test and evaluate an analytical instrument for children?s library environment based on a theoretical framework consisting of Howard Gardner?s theory of multiple intelligences and Thomas Armstrong?s pedagogical application of the original seven intelligences. We wanted to investigate whether the environment in Rum för barn stimulated all of children?s different intelligences. We also wanted to identify possibilities and liabilities within the analytical instrument.
