Listeriosis, which is caused by Listeria monocytogenes, is a rare food borne disease that primarily affects people whose immune system is weakened. These may be elderly people, pregnant women, new-born infants and individuals on immunosuppressive medication. The most common symptoms are meningitis, septikemia and abortion. The mortality is high, on average 20-30 %. In recent years the number of cases in Sweden has increased.

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

Den 1 januari år 2005 blev det obligatoriskt för EU-medlemmarnas börsnoterade bolag att redovisa enligt IASB:s redovisningsstandard IFRS. Införandet innebar genom IAS 36 att en årlig nedskrivningsprövning av goodwill ersatte årliga avskrivningar av goodwill. I praktiken har IAS 36 gett företagen möjlighet att tolka och därmed tillämpa IAS 36 på olika sätt; en neutral respektive subjektiv användning. Vid en neutral användning sker nedskrivningen av goodwill vid en faktisk värdeminskning av företagets goodwill, medan den subjektiva användningen utgår från företagsledningens egenintresse. Tidigare studier har visat att företagsledningen kommer att utnyttja sin handlingsfrihet om det finns agentbaserade motiv till det.Företagsledningens incitament att agera utifrån sitt egenintresse har förklarats genom agentteorin som beskriver hur separationen mellan företagsledningen och ägarna ger företagsledningen ett informationsövertag och därmed incitament att agera utifrån agentbaserade motiv.

There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.

Bakgrund och problemdiskussion: Earnings management kan v?cka fr?gor om trov?rdighet i den finansiella rapporteringen d? problematiken ligger i m?jligheten att vilseleda redovisningen. Anv?ndningen av ?big bath?-strategier och goodwillnedskrivningar kan skapa en snedvriden bild av f?retagens l?nsamhet genom att p?verka f?retagens redovisning. Utifr?n den unika ekonomiska situationen som COVID-19 utgjorde, samtidigt som regeringen tillhandah?ll omfattande krisst?d till f?retag, uppst?r nyfikenhet f?r hur f?retag kan ha hanterat sin redovisning, inklusive nedskrivningar av goodwill, under pandemin. I enlighet med IFRS ska f?retag genomf?ra ?rliga nedskrivningspr?vningar av goodwill, men p? grund av f?retagsledningens m?jlighet till diskretion?ra bed?mningar v?cks fr?gan om nedskrivningar av goodwill anv?nds som en form av earnings management i st?llet f?r att ?terspegla den korrekta bilden av f?retagens finansiella st?llning. Syfte: Syftet med studien ?r att studera omfattningen av nedskrivningar av goodwill bland b?rsnoterade f?retag i Sverige under COVID-19, samt om det finns tecken p? earnings management. Metod: Studien till?mpar en kvantitativ metod med deduktiv ansats.

J.O. Mallander?s Extended Play (1968) is a sound recording, a readymade, of the counting of votes in two presidential elections in Finland, during 1962 and 1968. A voice repeats monotonously: ?Kekkonen, Kekkonen, Kekkonen, Kekkonen, Kekkonen?? Although the Finnish president Urho Kekkonen represents, almost personifies, the politics of the post World War II period in Finland, Extended Play does not explicitly address the political. Rather, as this essay argues, it engages in the discourses of power and politics by providing a temporalization of its fixedness, or what Jacques Derrida terms the proper.Extended Play is, in parallel with Derrida?s critique of western metaphysics, a deconstruction in sound that challenges the state ideologies conveyed in the process of the counting of votes, where the presuppositions of the presence of the voice characterizes the ambiguities of power that Kekkonen?s politics of neutrality represent.Mallander?s readymade emerges as a double of the game theory strategies of the Cold War, a mimetic surplus of the administrative control mechanisms of sound recording.

The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate,  a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

The task in this master thesis was to design and construct a prototype of a satellite antenna driver unit. The unit is to be robust and work in cold weather down to -40°C, so that it can be mounted on the roof of a minibus. A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different levels and communicate at a multitude of signal standards..

The current legislation on marketing of tobacco products creates problems for Swedish Match, and obstruct its marketing communications. The purpose of this paper is to investigate Swedish Match's marketing strategy of product category snuff, through a special exposure. In store placement has a great affects on customer buying behavior and studies have shown that 70-80 percent of all purchasing decisions are made in the store, which in turn provides great opportunity for retailers to use their marketing tools for influencing customer buying decisions.Our thesis study is to test a double exposure of snuff with the help of three special exposure. These three special exposures are fridge, fridge with a sign and sign. The purpose of the study is to test which of these three special exposures that have the greatest impact on sales.

The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.

Enhet och helhetAv : Marcelo Rovira TorresVar börjar man när ett badhus blir till? Var började badhuset? Kanske var det vid havet, när höstkylan gjorde att vattnet blev för kallt och människor sökte sig till en plats där de kunde simma oberoende av klimatet. Tre badhus som uppfördes under folkhemsbygget under 1900-talets första hälft analyserades i tre svenska städer, Göteborg, Malmö och Luleå. Där framgick det tydligt att fokus låg på motionen och simbanan är byggnadens självklara mittpunkt. Bastun och tvagningen får sett till utformningen en sekundär roll, men funktionen är likväl viktig.

The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment. Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.
