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.

Aktuell forskning har visat att psykologiska faktorer spelar en viktig roll för upplevelsen av långvarig smärta. Denna studie undersökte effekterna av en KBT-behandling bestående av introceptiv exponering och avslappning för patienter med långvarig smärta. Studien använde en single-subject design där sex smärtpatienter genomgick en sex veckor lång individuell behandling. De variabler studien undersökte var i första hand förändringar gällande grad av acceptans samt upplevd smärtintensitet, i andra hand förändringar gällande smärtrelaterad ångest, rörelserädsla, katastroftankar samt funktion. Deltagande i behandlingen var förknippat med ökad acceptans, förbättrad funktion, minskad smärtintensitet, minskad smärtrelaterad ångest, mindre katastroftankar samt minskad rörelserädsla.

When single-family lots are valued for development of new residential areas,the valuation is influenced by several factors. The valuation is a matter ofdefinition that varies according to its interpreter. Previous research conductedin other countries, has identified a number of value-influencing factors. Thesefactors are the basis for this study.The study's purpose is to highlight the value-influencing factors thatcustomers value and are looking for in the choice of single-family lots. Thestudy also seeks to determine if there is an unknown difference between howprofessionals and clients value single-family lots.The study showed that the value factors considered important for customersand also professionals are consistent and applicable with the factors reportedfrom previous research.

Depression är vanligt hos personer med Borderline personlighetsstörning (BPS). Det finns risk för att komorbid depression försämrar behandlingsutfall och minskar sannolikhet för remission från BPS, en problematik förknippad med signifikant funktionsned-sättning. Denna studie syftade till att undersöka hur patienter med BPS och samtidig depression, svarade på beteendeaktivering inriktad på att konkurrera ut ohälsosamma beteenden med hälsosamma. I single-case design om fyra patienter, registrerades aktivitetsnivå dagligen samt upprepade mätningar med validerade skattningsskalor under baslinje och aktiv intervention. Resultatet visade att patienterna hade stora svårigheter med registrering och närvaro, och att även om hälsosamma beteenden ökade i vissa fall så påverkades inte grad av depression..

Early contact with both parents is important for children and it is important to reach out to both mothers and fathers through parental education groups. Parent education program for fathers can lead to more fathers taking parental leave and becoming more involved in the care of their children. A lot of men lack support from the community after the birth of their child. The aim of this study was to illustrate district nurses? experiences of meeting first-time fathers.

The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect. Trees were harvested and divided into bunches based on diameter.

Despite the fact that men dominate substance abuse research and that most programs to target substance abuse therefore are developed by and for men, very little is known about the fact that substance abusing men can also be parents. Mothers are up until today regarded as the most important parent even though society is changing and fathers are taken a more active part in childrearing. The average father today still spends significantly less time with his children than the average mother does and marginalised drug abusing fathers often disappear from their families altogether. The goal and purpose of this paper has been that through a qualitative analyses of written sources and qualitative interviews with healthcare professionals and social workers recognise how marginalised drug abusing fathers interests of taking part in their children's lives are met by healthcare, treatment and child protection agencies and how we can understand marginalised fathering as an extension of how we view ordinary fathering. I wanted to examine if there are any specific actions taken in involving these men as fathers and how we can understand their situation.

During this project a photographer and an illustrator have explored if a single image can communicate a bigger whole, in this case a movie. By analysing five motion pictures with visual communication theories, semiotics and colour symbolism as tools, ten images was created. These images do not only consist of symbols, but also communicate the overall feeling and colour scheme of the movie.These images have been tested in interviews with six individuals, who, except for one, work with visual communication of some kind. They have studied the communication skills of the images from their own experiences.The result of the interviews showed that all images could not communicate a movie. One reason for this was that only a few of the test persons had seen two of the selected movies.

Society has an obligation to offer parents support of various types, an example of such a support is ?parent support?. The purpose of this study has been to describe midwives and child health care nurses conceptions of the need for early parent support. The definition of early parent support in this study is the first two weeks after delivery. Since the 1970:ies the Swedish delivery and ?BB? care has changed in that the time in hospital care after delivery has been reduced from in average six days, till an average of two days.

Studien som utförts analyserar ur ett sociosemiotiskt och multimodalt perspektiv vilka resurser läromedlet "Insikter i svenska" använder sig av. Läromedlet är riktat mot ungdomar i första året på gymnasiet som läser en yrkesinriktad utbildning. Studien redogör för ett antal utgångspunkter för multimodal bildanalys och påvisar även att lärmedlet innehåll ett antal av dessa resurser. .

Simplicity, intimacy, freedom and one single threadcharacterize the knitting technique.In my project, I have studied ways of creating three-dimensional shape and structure using single threads and various knitting techniques. I applied my ideas in a collaboration with the singer Sofia Karlsson. The focus has been to design a portable object that can be used in pictures for the cover and promotion of her upcoming album.The material I studied, processed and used in creating the three-part object was linen. In the center stands a collar, that changes expression depending on how it is worn and which side is turned towards the outside. The collar interacts with a cylinder for her hands and a hairnet.

There are several factors influencing the profitability of production with sheep. Two of the most important factors are ewe fertility and lamb survival. Also growth capacity of the lambs is important. This paper aims to review correlations between the ewe?s fertility and maternal behavior and lamb survival.

I många utvecklingsländer finns en begränsad tillgång på utvecklade AKK-system (Alant, 1999) och ofta även en okunskap kring möjligheterna att arbeta med kommunikationsproblem (Marshall, 1997). I föreliggande studie genomförs intervention i alternativ och kompletterande kommunikation (AKK) för två deltagare med cerebral pares på ett dagcenter i Kilimanjaroregionen, Tanzania. Syftet i föreliggande interventionsstudie är att genom intervention studera och utveckla de i mätsituationerna responsiva talakterna att påkalla uppmärksamhet för att inleda interaktion, acceptera och avfärda samt upprätthålla och avsluta interaktion. Detta sker med hjälp av begreppen ja och nej för att acceptera och avfärda, liksom mer och mindre för att upprätthålla och avsluta interaktion. Studien följer en single subjekt design och insatsen utgörs av två interventionsperioder, bestående av direkt intervention med deltagarna samt utbildning och fortlöpande handledning av personal.

White- and blue collar workers traditionally belong to different unions and, therefore, are covered by different collective agreements. Collective agreements for different employee categories create internal divisions, which mean that white collar workers are not obliged to do work that falls under a blue collar agreement and reversed. Historically the difference between white- and blue collar work has been fairly sharp and so has the difference between collective agreements. Due to the continuous development of technology white- and blue collar work within production has become less clear. This has resulted in an increasing amount of disagreements regarding what collective agreement should apply and whether the employee is obliged to perform different work tasks.
