One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

The purpose of this study was to examine the threats from climate change coverage in the media. The climate threats start to appear more frequently in the media and because of that it is important to examine what the media conveys to the viewers and readers since it may effect how people act when it comes to climate threats. In this study newspaper has been examined, more specifically daily press and evening press. The papers chosen was Aftonbladet and Expressen, which represented evening press, and Dagens Nyheter represented daily press.The method applied was both a quantitative and qualitative text analysis. With the quantitative method variables were formed and tested against the material.

If Swedish companies are to compete with companies in low-cost countries they have to achieve a more efficient production. The purpose of Total Productivity Maintenance (TPM) is to increase the company's profitability by increasing the productivity. TPM is a method that involves all employees and aims to prevent failures in order to increase the availability of existing equipment.The aim of this paper is to evaluate the implementation process of TPM and give recommendations for the further implementation process. The conclusion and the analysis are based on a case study done at a production department at ABB Cewe-Controls facilities in Nyköping. The case study consists mainly of qualitative data from participation observations, surveys and interviews.Commitment of the management is a key factor in the implementation process of TPM.

Summary The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.

Syftet med denna studie är att beskriva och analysera hur ledarna för Katedralskolan i Växjö arbetar med att motivera medarbetarna vid införandet av en intraprenad. Fokus i denna uppsats är i första hand information och kommunikation ur ett ledarperspektiv men även till viss del utifrån ett medarbetarperspektiv..

The main purpose of this study was to determine the impact of bedding material on the faecal microflora of horses. Another objective was to investigate the hygienic and physical qualities of the bedding materials used and how these may change in the course of the trial period. The bedding materials used were sphagnum peat and wood shavings. Six horses had each material as bedding for a three week period in a change?over experiment.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

The aim of this paper is to empirically examine the ideological trends and positioning of the Swedish liberal party with the Danish social liberal party. This paper also aims to analyze the reasons behind the trends. By examine the development in these two Nordic liberal sisterparties, this paper contributes to our understanding of why and how party change is initiated. The paper commences with an intuitive notion that the Swedish party has in fact, made a lurch towards the right, during the past ten to fifteen years while the Danish party has retained their social-liberal position in the centre of the Danish political spectrum. The questions then asked are: can this hypothesis be verified empirically? If so, how can this phenomenon of divergence, be explained?The method used in this thesis is process-tracing and the empirical material does to a large extent rely on interviews with central agents as they are specified in the theory of each party.

The aim with this study was to examine which information sources are used by the librarians in the process of changing automated library system and why. Furthermore it was of interest to examine whether there are any correlations between variables environment, information quality, information availability, information need and information sources. I used a quantitative method that was carried out in form of a nationwide survey. Questionnaires were sent out to all the Swedish libraries that had change library systems sometime between the years 2000.

The goal with this work is to study the settlement during the Middle Neolithic B. Looking at the settlement pattern of the Battle Axe C culture (BAC) in Scania we might be able to get a picture of how the social structure of the BAC looked like and how it differed from' earlier and later culture groups.. What can a change in settlement tell archaeologists today about this and what problems do archeologist have to take into consideration..

Detta projekt syftar till att utreda om metoden Lane Change Test (LCT) kan mäta hur förare distraheras av att utföra andra uppgifter under körning och om metoden kan användas för att avgöra när användning av ett system i fordonet under körning blir trafikfarlig. Projektet har utförts på Scania CV AB i Södertälje. Förarmiljön blir allt mer komplex och mer teknologi plockas in i fordonen, vilket innebär att risken ökar för att föraren distraheras. En önskan från fordonsindustrin är att kunna mäta distraktion som ett system alstrar, för att försäkra sig om att de system som förs in i fordonet inte är trafikfarliga. En metod för att mäta förardistraktion är LCT, som är under utveckling och utreds för att bli en standard.

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts. Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance. This literature has illuminated a major environmental problem and it has been suggested optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a definite answer for the optimal method for each site tests should be carried out, this because many factors determine to what is suitable for each, specific environment. .

Min ambition har varit att operabyggnaden ska imitera och spegla platsens karaktär och unika läge i staden.Galärvarvet är ett område som har direkt närhet till både staden (Strandvägen och Östermalm), parken (Galärparken och resten av Djurgården) samt till vattnet (Ladugårdsviken och Mälaren). Dessa tre stadselement är också starkt karaktäriserande för Stockholm som stad. Intentionen var dessutom att operabyggnaden skulle kunna erbjuda staden något mer än bara opera som konstform och att den ska vara inbjudande och tillgänglig både interiört och exteriört även för de som inte uppskattar operakonsten. Fasaden mot Strandvägen är till stora delar glasad med ytor för operabesökare, balettsalar, orkestersalar och loger för artister samt musiker som kommunicerar operans verksamhet mot staden. Längs med denna fasad löper en lång ramp för besökare ner till den lilla scenen och restaurangen.

Detta självständiga arbete syftar till att ge ägarna till Château du Grand Val, Roland och Marie Nilsson ett utvecklingsförslag på de södra delarna av egendomen där deras mål med fastigheten är hörsammade och där planen är så tydlig att de kan följa den utan större svårigheter. Genom studiebesök, fält- och litteraturstudier har de södra delarna av egendomen fått ett nytt stigsystem där tyngdpunkten ligger på upplevelserikedom och orienterbarhet. Studiebesöken på Château du Grand Val har gett en bakgrundsinformation som sedan har använts till analyser över området. Analysmetoder som har använts är Patrik Grahns åtta parkkaraktärer och Gordon Cullens Serial Vision. Den första har använts som analys av vegetationens egenskaper och den andra för att analysera stigsystemet. Dessa analyser har sedan legat till grund för utformningen av stigsystemet och utvecklingen av den omgivande vegetationen. Arbetets fokus har legat på att skapa sammanbindande stråk mellan befi ntliga stigar och därefter anpassa vegetationen för att förstärka upplevelsen av stigen med hänsyn tagen till att gynna viltet på egendomen och den småskaliga skogsproduktionen. Resultatet redovisas i både text och illustrationer. Det innehåller en utförlig plan för skapande av ett sammanbindande stigsystem.
