Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Bröstcancer är en sjukdom som ofta bringar lidande och är viktig att förebygga. Utövande av fysisk aktivitet har i tidigare studier visat sig ge en minskad risk för att få bröstcancer. Litteraturstudiens syfte var att skapa en översikt över sambandet mellan fysisk aktivitet och bröstcancer hos kvinnor. Sökning, urval och granskning av artiklar har utförts. Resultatet visade att fysisk aktivitet hade ett starkt samband med minskad risk för att få bröstcancer för både pre- och postmenopausala kvinnor.

The purpose of this master?s thesis is to find out in which ways a group of first generation immigrants use Swedish papers and magazines in a public library and which information needs this group has about Swedish society. One important aspect in this essay is integration of immigrants in the Swedish society as a possible effect of newspaper reading. The method used in this study is qualitative. Data is generated through semi-structured interviews.

Introduction: Taxes result in a big cost for corporations which create an incentive for tax planning. Previous studies have demonstrated that it's the management team and the board of directors that influences to what extent the corporation is going to tax plan. We want to study underlying factors for how the composition of the groups affect the tax planning in a corporation based on four demographic traits; sex, nationality, age and duration.Purpose: The purpose with the study is to explain how the composition of the management team and the board of directors affect the corporations tax planning.Method: The study has a deductive approach where theories about the composition of the board of directors and the management team have been used to derive hypothesis. The empirical material has been collected from Nasdaq OMX Stockholm. Two different measures have been used to calculate the corporations tax planning.Results and Conclusions: The result of the study demonstrates that the composition of both the board of directors and the management team has an effect on corporations tax planning.

Bakgrund: Nyblivna mammor rekommenderas att amma under barnets första halvår. År 2008 ändrades den nationella rekommendationen till att ammande kvinnor kan dricka alkohol i måttlig mängd. Syfte: Att undersöka vilka attityder föräldrar uttrycker på föräldraforum angående alkohol under amningsperioden. Metod: Data samlades in genom att undersöka föräldrainriktade webbsidor för att hitta inlägg om föräldrars attityder till amning och alkohol.  Totalt valdes 40 inlägg med medföljande svar, skrivna mellan 2008- 2013, från tre föräldraforum ut.

In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

The purpose of this study is to find out how social workers in one medium and one smallmunicipality in central Sweden perceive the need of financial support for young adults formore than one year and what the causes might be. To answer our research questions aqualitative research method was used and four social workers were interviewed. The resulthas been analyzed based of social exclusion, stigma, as well as on structural and individuallevel and linked to previous research. Our results show that although young adults are anexception for long duration for financial support, there are those who lack other means ofsupport for a long time. The results also show that young adults often are recurring in thesocial services, and they are long-lasting.

SAMMANFATTNING Amningen kan ibland vara svår att komma igång med. En del mammor får det att fungera utmärkt medan andra behöver mera stöd. Baby Friendly Hospital Initiative (BFHI) och ?tio steg till lyckad amning? var tänkt att uppmuntra amningen på BB genom åtgärder som utbildning av barnmorskorna i att stödja mammorna. Syftet med denna studie var att beskriva mammors känslor inför amning och deras upplevelse av stöd från personal och pappa under BB-tiden samt att jämföra med en grupp mammor från 1993.

Vid start av amning är det viktigt att modern känner att hon kan få stöd från anhöriga och från experter. Om amningen inte fungerar kan mamman få svårt att knyta an till sitt lilla barn och mamman kan börja tvivla på sitt moderskap. Barnavårdcentralsjuksköterskan (BVC-sköterskan) har en framträdande roll som amningsstödjare. BVC-sköterskan behöver därför ha mycket kunskap kring barnets behov och ha en förmåga att kunna samtala med föräldrarna. Det ligger på BVC-sköterskans ansvar att mötet med mamman blir vårdande.

The study deals with the causes of unjustified differences in pay between women and men in the banking sector. The purpose of this paper has been to examine how a gender project implemented in the private banking organizations from a gender-and implementation perspective. The aim of the project examined is to even unjustified differences in pay between men and women in the banking and finance sector. The main issues are: ? How has the project been implemented and what are the real and perceived results? ? How can the opportunities and barriers to successful implementation course with emphasis on gender? The method used is a qualitative study, where the empirical material consisted of focus group interviews.

The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response (Frishman, 2006; Zrenner and Gouras, 1979). In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones. These stimuli gave ERGs with both ON- and OFF-responses.

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.
