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.

According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for producing ethanol and is the leading producer and exporter of fuel ethanol. My purpose with this paper is to investigate why Brazil decided to develop ethanol production on a large-scale operation and to find out today?s situation. Focus will mainly be on ethanol production with sugarcane as a feedstock.

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

Medarbetarsamtal i grupp är ett relativt nytt och outforskat ämne. Den här uppsatsen undersöker fenomenet medarbetarsamtal i grupp, och bygger på en fallstudie gjord på Pilkington i Halmstad. Syftet var att med utgångspunkt i medarbetarnas upplevelser analysera vilka förutsättningar för individens utveckling som skapas i medarbetarsamtal i grupp. För att uppnå syftet genomfördes en kvalitativ undersökning med hjälp av semistrukturerade intervjuer med sex medarbetare som alla hade haft medarbetarsamtal i grupp.Resultaten pekar mot att de förutsättningar som ges för individens utveckling i medarbetarsamtal i grupp på Pilkington i många avseenden inte lever upp till förväntningarna. Det visade sig att feedback, reflektion, målsättning, attityder och uppriktighet på olika sätt bildar förutsättningar för individens utveckling i medarbetarsamtal i grupp.

Scarcity due to supply, demand or in time is all factors that affect consumers´buying behavior. The scarcity principle describes how scarce resources appear moreattractive to the customer's eyes than unlimited does. When something is scar thecustomer often draws parallels to the quality and price, that the product will bemore expensive and better. People hate to be deprived of choices. When a certainproduct is scar, the customer will desire the product even more.

The change in course recently taken by the Swedish Armed Forces results in an increased use of equipment, and thereby increased requirements of preventive maintenance. This paper aims to examine the current responsibilities for preventive maintenance in an army unit. The intended effect of this examination is to disclose possible flaws, and to help make routines for preventive maintenance more effective.The questions asked in this paper are;Who, in an army unit, is responsible for the routine maintenance?When is this responsibility valid?What demands does the technical service have on responsibilities for the routine maintenance?How are these demands met?How ought to be responsible for the routine maintenance?To answer these questions the author has chosen to use a descriptive method to show the current facts. A theorizing method is chosen to, from described facts, clarify the demands of the technical service on routine maintenance.

Community Supported Agriculture (CSA) is an unconventional model of agriculture expected to contribute to a more sustainable food supply and a sustainable landscape; the development of rural areas; a stronger relationship between producer and consumer and a healthier diet. This study, with a focus on food production and the link between the producer and consumer, describes the origin and current development of CSA in Sweden, including the prerequisites for CSA in a Swedish context. Organizations and entrepreneurs working with CSA and related projects are identified and interviewed. The notion of CSA in Sweden is still in its infancy, but a rapidly growing interest currently can be detected. The fact that the identified CSAs are found in different Swedish regions with variations in degree of urbanization and intensity of agriculture indicates that the prerequisites are there for the concept to grow, both in rural as well as urban areas.

In this report listed buildings, according to the Swedish Heritage Conservation Act, have been studied with a focus on cases where economical compensation has been given to the owner of the building and cases where the listing of the building has been appealed by the owner. In order for a building to become listed it needs to be particularly valuable from a cultural and historical standpoint. The listed buildings are protected through a list of regulations that determines which parts of the building can or cannot be changed, what methods and materials should be used for changes and repairs, and how the building should be maintained. These regulations should as far as possible be formulated in agreement with the owner, but a building can become listed against the owners will. To decrease the damage this causes the owner he can in some cases have the right to economical compensation. There is also a possibility for the owner to appeal the listing of the building.

Abuse of alcohol is one of the biggest problems that society faces today. There are between three and four hundred thousand abusers in Sweden. In addition there are about three hundred thousand over consumers. The government bill proposed in 1977 gave the labour market most of the responsibility to solve the problem. They thought a meaningful job and a spirit of community were the most important factors to decrease abuse of alcohol and social rejection.

AbstractTitle: From old rightwing-ghost to the new labour party ? The new conservatives political communication during the Swedish election 2006Authors: Pontus CarestenAim: The aim of the essay is to study how the conservative party communicated during the election campaign in 2006. I wish to find out how political parties work in todays society and how the communication has changed over time. To get relevant results I will also see how the theories and empirics interact. The purpose is further to illustrate the new conservatives? campaign work from a senders point of view.Method/Material: I have chosen a qualitative method which consists of three interviews with relevant key persons.

The danger and vulnerability associated with a preterm birth seem to be closely correlated with a dysfunction of the fetal hypothalamic-pituitary-adrenal (HPA) axis, whose maturation in the foal is without a doubt as delicate as it is important. Not only is this endocrine cascade vital for the foal in order to cope with neonatal stress, it also appears to be fundamental for the final fetal intrauterine maturation, as well as for the onset of foaling. Equine gestation exhibits some rather unique features, indicating a somewhat different significance of the endocrine changes associated with HPA maturation, compared to many other species. This hormonal cascade is rapid and confined to a narrow time during late gestation in the horse, and the risk of the foal completely missing it therefore becomes prominent. Induced parturition in the mare may be operated through uterotonic agents, which occasionally bring about premature foals. Desirable seems the ability to initiate equine labour while simultaneously enhancing fetal HPA maturation, as in humans and ruminants through perinatal glucocorticoid administration. However, similar treatment in the horse has resulted in various, sometimes fatal, outcomes. In the light of the distinctive features of equine gestation, difficulties are encountered following such administration of glucocorticoids and ACTH.

In today´s labour market, men and women are segregated, both vertically and horizontally. Exceptions to the rule of gender segregation are few. There is, however, one managerial group where women and men are equal in numbers: school principals. In a short period of time, the distribution in terms of sex among principals in Sweden has changed dramatically. How does gender equality in numbers affect gender equality in a qualitative sense? That is the focus of this thesis.

This paper investigates the science fiction novels of Swedish crime writer Per Wahlöö, most famous for his collaboration with his writing partner Maj Sjöwall on the ten Martin Beck mysteries. During two important years, 1964 and 1968, Wahlöö wrote the novels Murder On the 31st Floor and The Steel Spring, set in a near future land ruled by a social fascist power structure where political opposition is eradicated. The pretexted notion of this paper is that these novels consists of extensive quantities of criticism against the Swedish welfare state and the monopoly-capitalistic Swedish press during the sixties. Through the lens of science fiction theory and the notion of the novels as historical sources this paper concludes that PerWahlöö´s science fiction becomes a bridge between the classic Swedish detective novel and the new social critic crime fiction in the style of Sjöwall-Wahlöö and others. The novels are also representations of the historical process in the mid-sixties during the radical turn: the sci-fi novels as social criticism of the contemporary society ? an utopian flare.
