Kackel, kvitter eller pip - uttryckssätten i twitterskogen är många. En kvantitativ studie om olika strategiers potential på Twitter.

Internet and social networks have become important features in today?s society. We spend numerous hours on browsing and communicating through these platforms. This development has also led to a shift of power from businesses to consumers. Today?s consumers have more control of if, when and what messages they are exposed to.

Glycerol till mjölkkor : effekter på våmmetabolismen

Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.

Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.

Organisationens påverkan på förbättringsarbete : En fallstudie av fo?rba?ttringsarbete och fo?rslagsverksamhet vid Volvo Powertrain

This thesis was commissioned by Volvo Powertrain, where manufacturing and assembling of transmissions is performed, which is used in the company's trucks and buses. The thesis has consisted of a case study that intends to study the problem areas in the current proposed activities and continuous improvements in the assembly department in the Volvo Powertrain facility.In the current situation, the proposals that are submitted by the employees suggest mainly minor improvements. The proposals concern for example, labelling of materials boxes and holders for tools, which do not generate any significant profit for the company. Directors and executives want an increased amount of proposals with a more results-oriented type, in terms of reduced costs, time consumption and stops, and improved quality. The company would also deal with the problems that arise when implementing improvements in the production.

Vem är det framför skärmen? : En fördjupad textanalys om hur svenska politiker konstruerar jag-bilder på Twitter.

The trend of social media is a global hit and now both individuals, businesses, celebrities and politicianshave their own social media pages, which means that the visibility increases and focus lies on what'swritten and published by the person. Mediated communication are everywhere around us and affects theway we communicate with each other and also the way we look at ourselves and most importantly how weportray ourselves. The individual's perspective has become a relevant issue with the rapid moderndevelopment. One's cultural identity can be seen as a life-long project.The purpose of this paper is to do an in-depth text analysis to examine how Swedish politicians constituteand construct identities, with a focus on "the self" and the "mediatization self" on the micro-blog Twitter.The theoretical ground for this study is from a discourse analysis point of view that focus on ?the self? andthe ?meditization self?.

Mobil mikrobetalning - Betalningslösningen via SMS : En studie kring en SMS-baserad betaltjänst

I detta arbete har vi studerat tjänsten SMS-betalning. Vi har fokuserat på att utvärdera och beskriva tjänstens användningsområde samt dess styrkor och svagheter. Utifrån företaget Mobill, vars affärsidé är att utveckla en betalningstjänst via SMS har vi fått en bild av hur ett företag kan satsa på denna teknik. I en studie med konsumenterna har vi visat den generella bilden av inställningen till betalningstjänsten, detta för att vidare kunna utvärdera betalningssystemet. Dessa studier har båda en kvalitativ karaktär.

Effekt av olika kvävegödselmedel på utvecklingen av klumprotsjuka i salladskål (Brassica rapa ssp. pekinensis)

The price trend on rapeseed the latest years has led to an increasing interest to grow the crop among many farmers in Sweden. The price trend has resulted in more than a doubling of the oilseed area since the early 2000s. For many farmers it is an advantage to increase cultivation of rapeseed because of the high proportion of cereals in the crop rotation on many farms, but it is not just benefits. The risk of the fields being infected by clubroot increases within frequent rapeseed cultivation and it often leads to subtantial economic losses. Clubroot is caused by Plasmodiophora brassicae that is a soilborne pathogen in genus Protozoa and its resting spores can be found in the soil for up to 18 years.

Prissättningen av bostadsrätter: Vilka faktorer påverkar priserna, vad är riktpriset för en lägenhet?: - En mikrostudie av Södermalm i Stockholm

Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.

Vaddå ekonomisk utsatt? : Tankar om ekonomisk utsatthet bland barnfamiljer med utländsk bakgrund i Växjö kommun

AbstractThis thesis is centered on the economic condition and background of immigrants living in Sweden, with focus on Araby, Växjö. To guide us through this enormous work we formulated research questions, which are:Why have foreigners (immigrants) a greater risk of becoming economic vulnerable? How does economic vulnerability effect families with children?What strategies do families adopt under hard economic conditions? What strategies does the society adopt in assisting families, by economic aid, that are economic vulnerable?  Our sample was from a school where we administered an open ended questionnaire to selected students and we also had a comprehensive interview session with ten families in the community so as to have a complete picture of their living condition and how they think people are economically vulnerable.We concentrated on the causes, consequences and strategies of how economic vulnerability is handled by immigrants in Sweden. In our analysis we found out, though our respondents? answers, that the causes of economic vulnerable are background, language, priorities et cetera.

Mikrosimulering för analys av Mästergatans förlängning i Enköping

Two of the main approach roads into the city of Enköping are Salavägen and Stockholmsvägen. They are connected to each other through the street Bangårdsgatan in the roundabout Salatullen and crossing Fannakorset, respectively. These crossings are from time to time heavily loaded, which is why the municipality plan for a new street in parallel to Bangårdsgatan. The traffic will then be spread out and is thereby reducing the density. The new street is actually an extension of the existing Mästergatan, a side street to Salavägen, to the east and connecting it to Stockholmsvägen or a street nearby.The purpose of this Master thesis is to show how the new street can be drawn in order to discharge the traffic in the area between the roundabout Salatullen and the crossing Fannakorset.

Ett klick ifrån ett varumärke? : En studie kring hur svenska mikroföretag bygger upp sina varumärken på Internet.

Nya möjligheter leder till nya utmaningar. I takt med att privatpersoners användande av Internet ökat explosionsartat, har även företagens närvaro ökat markant. Företagen ser möjligheter då kostnaden för marknadsföring och varumärkesbyggande on-line ofta är lägre än att gå via de mer traditionella media kanaler. Internets natur gällande kommunikation ger företagen en möjlighet till att närma sig konsumenterna och bygga en relation till dem.Studien ämnar skapa förståelse för hur svenska mikroföretag inom mode använder nya mediekanaler för att bygga upp sina respektive varumärken. Således utfördes ett förståelseinriktat arbete där den empiriska basen består av fyra stycken semistrukturerade intervjuer med tre mikroföretag samt en med en PR- konsult.

Djupströbädd -bra för miljö och djur?

Deep litter is a system for animals kept in separate stalls, loafing and bedding in wind shelters. The litter can consist of different bedding, like straw and peat. The system is allowed to build over and to ensure optimal proportions it is necessary to add new straw regularly and to have good conditions. Important conditions are aerobic state, humidity, amount of organic substance and acceptable temperatures in the litter. The micro organisms are depending on temperature for their living conditions and to get the bottom layer in the litter to start burning.

Djurförbud : en analys av domar enligt 29 § Djurskyddslagen samt definition av resurs- och funktionskrav

The aim of this study is to with the help of my data, conduct statistic analyses about animal welfare mistakes and scarities, as a preventive measure for the public sector point of view and how farmers handle their animals in these cases, when and how these mistakes and scarities are likely to appear and in this way perhaps manage the existing problems. The aim of using judicial decisions of banning ownership and caretaking of animals according to the 29 § is that this judicial decision is the outermost fortification of animal welfare. In November 1938 the pro tempore investigator handed over a report with a proposition according the animal welfare legislation. Pro tempore proposed that the court should in some cases, be able to order a person guilty of cruelty against animals to a ban of owning or taking care of animals. This proposal unfortunately was turned down. The question about introduce a ban against owning or taking care of animals into the Swedish animal welfare legislation was again discussed in April 1967 at an interpellation debate in the parliaments second chamber.

När världen kom till Föra : om forskningens syn på Ölands kristnande

This paper aims to give an account of, and to discuss the view-points and theories of different researchers on the christianization of Sweden, especially the province of Öland, during the early middle ages. Its purpose is to investigate how, and in what sense, their positions can be said to correspond to what we may know of the historical ?facts?. This will be possible by comparing different points of view with a study of the development in a single parish. An overall difficulty however, is the nature of the sources relating to the time in question, they are scarce or even non-existent.Part I of the paper consists of an outline of the field of research and the different theories put forward on the subject.

Smarttelefon-sensorernas möjligheter - En studie om barometer-, GPS- och accelerometersensorer. The smartphone sensor possibilities - A case study featuring the barometer, GPS and accelerometer sensors

Denna rapport sammanfattar resultat av ett examensarbete på en högskoleingenjörsutbildning som utfördes av två studenter på Malmö högskola. Arbetets syfte var att genomföra en mängd olika experiment med accelerometer, barometer och GPS i en modern smarttelefon. Ett antal scenarier för en tänkbar sensoranvändning i applikationer formulerades för att vägleda olika experiment. Experimentdata dokumenterades noggrant och analyserades med avsikten att skapa en databank med information för framtida studier. Analys av data inkluderar höjdbestämning i naturen och i byggnader med hjälp av barometersensor, geografisk position med hjälp av GPS, hastighet och acceleration under en hissfärd med hjälp av accelerometer. Rapporten innehåller en omfattande litteraturstudie om användning av sensorer vid inomhuspositionering. Från analys av mätdata, kom vi fram till slutsatsen att är möjligt att beräkna höjden från barometerdata med bra noggrannhet under optimala omständigheter. GPS höjden från mätningarna har stor felmarginal jämfört med den verkliga höjden samt när den jämförs med den beräknade höjden från barometern. Genom att utföra en numerisk integration på accelerometer-data kom vi fram till att det är möjligt att beräkna ungefär hur långt man har färdats med en hiss, dock att vissa detaljer måste tas i beaktning..
