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.

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.

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.

Titel: Den osminkade sanningen - En lönsamhetsanalys av en sminkavdelning idagligvaruhandelnBakgrund och problem: Svinn i detaljhandeln innebär problem för lönsamheten idetaljhandelns organisationer. Om en fullständig kostnadskalkyl görs på en avdelning idetaljhandeln som idag är lönsam, framstår avdelningen därefter fortfarande som lönsam?Syfte: Syftet med studien är att, med hjälp av en kalkyl, göra en analys på lönsamheten på ensminkavdelning i en dagligvarubutik, samt att jämföra detta resultat med liknande underlagfrån en jämförbar butik. Vidare syftar studien till att om möjligt ge förslag till förändring samtatt utöka det empiriska underlaget kring kalkylering inom svenska organisationer.Metod: Undersökningen har genomförts med hjälp av kvalitativa metoder såsom intervjueroch bearbetning av insamlad data.Resultat och slutsatser: Butikerna i studien visade varierande lönsamhet, såväl positiv somnegativ beroende på hur beräkningarna genomförs. Denna lönsamhet skiljde sig från vadbutikerna enligt sina metoder beräknade.Förslag till vidare forskning: Utförande av en liknande studie, fast på en annan avdelningsåsom en charkavdelning eller fruktavdelning.

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.

The first aim of this study is to examine what the differences are between the Classic directive (directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts) and the Revised Classic directive (directive 2014/24/EU of the European Parliament and of the council of 26 February 2014 on public procurement and repealing Directive 2004/18/EC) when it comes to social considerations in public procurement. The second aim is to examine if the revision of the directive has solved the prior existing problems regarding social considerations in public procurement. In this paper a traditional European legal method is used. The examinations show a number of things, including the Revised Classic directive involving codification of case law, references to other sources of law and some clarified rules as well as new provisions. The regulations regarding reserved contracts, technical specifications, and selection criterion are satisfied in the Revised Classic directive.

It is also important to use a relationship marketing approach. .

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.

ABSTRACTIn an intermediate section at a large university hospital are patients with subarachnoid hemorrhage (SAH) cared for. There are international, national and local guidelines how nutrition therapy should be implemented and how much energy each patient should be given when hospitalized. The purpose of this study was to examine the documentation and actions on nutrition in patients with SAH and to see if guidelines on nutrition were followed. The study was a quantitative, retrospective record review that was analyzed statistically and descriptive. 26 patients were included.

Toxoplasma gondii är en encellig parasit som kan orsaka livshotande sjukdom vid infektion av immunsupprimerade personer och skada fostret vid infektion av gravida kvinnor. Parasiten infekterar även livsmedelsproducerande djur som t ex nötkreatur och kan då ge upphov till infektiösa vävnadscystor som förekommer i bl a skelettmuskulatur. Detta gör konsumtion av kött till en viktig smittkälla, men vilken roll just nötkött spelar är inte klarlagt. Med anledning av detta har jag gjort en litteraturstudie avseende förekomsten av T. gondii hos nötkreatur.
