Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

Social media is by many believed to be the core of a new type of Public Relations. This new PR is called PR 2.0. Most larger companies today are to be find using dif- ferent types of social media to interact with their publics. Each year companies invest more money in this type of digital public relations. Social media is a relatively new online phenomenon and still used at a very early stage.

Uppsatsen syftar till att bidra mot ökad förståelse för användandet av Air Power i olika miljöer.Uppsatsen strävar efter att belysa på vilket sätt man har nyttjat högteknologisk Air Power för atterhålla optimalt operativt övertag samt att undersöka vilka risker det eventuellt har inneburit.Detta uppnås genom att studera tre konflikter under 1990-talet och se hur man har använt sig avAir Power och titta på vilken effekt detta har haft. Det primära syftet är alltså att undersöka omhögteknologi är fördelaktigt att använda i olika nivåer av konflikter, eller om avsevärda nackdelarvisar sig.Uppsatsen syfte har också varit att identifiera hur de insatser som genomförts med dominerandeAir Power har påverkat och påverkas av teknologiska utvecklingsskillnader mellan länder.Då all krigskonst handlar om hur man nyttjar sina förutsättningar på bästa sätt blir det logiskasteget att en mindre teknologiskt utvecklad fiende kan göra högteknologisk krigföring ineffektiv.Följande hypotes prövas under arbetet: Högteknologisk Air Power är effektivt även vidasymmetrisk krigföring och vid lågintensiva konflikter.Resultatet ur studien visar att det finns både positiva och negativa effekter. De mest framträdandefördelarna är att teknologin medger flexibelt nyttjande och korta omloppstider, underlättarsamarbete och innebär vidare att ett högt tempo kan hållas genom operationen.Och nackdelarna är att det visar sig vara relativt enkelt att försvara sig under lång tid med småenkla resurser, detta kan visa sig svårhanterat för den politiska nivån. Resultatvärderingen avinsatta medel sker änsålänge alldeles för långsamt.En högteknologisk angripare gör fienden rörligare vilket i längden innebär svårigheter för denegna beslutshanteringen..

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

This paper treats the question about how the internationally established company, Apple, is affected by intern or extern events when it comes to the trade market. The purpose of the study is to investigate if chosen events create abnormal return on Apples stock market. The chosen research area is Steve Jobs three sick-listings, It-bubble and the purchase of the search engine company Siri. The reason of writing about this is the big interest for the stock market and its function.This study methodological starting position is quantitative done by an event study, with qualitative feature done by an interview with an expertise within this area. When analyzing the empirics, we have used the efficient market theory that says that information should not affect the stock market in the degree that abnormal return creates.

The aim of this paper is to investigate to what degree the groups in our inquiry work independently. It is a qualitative research, which points to a well?functioning unit, that by definition is not self-governing, but has many traits of self- government. We have reached to the conclusion, that complete self?government does not have to be the best solution, if you want both quality and efficiency.

Sammanfattning Titel: Återuppbyggnad av strukturer efter en kris Författare: Lisa Mattsson, Emma Lindmar Handledare: Camilla Wernersson Institution: Managementhögskolan, Blekinge Tekniska Högskola Kurs: Kandidatarbete i Företagsekonomi, 10 poäng Syfte: Syftet med denna uppsats är att ur ett meningsskapande perspektiv bidra till en ökad kunskap och förståelse om hur interaktioner mellan människor i en organisation kan återuppbygga strukturer efter en kris. Metod: För att nå vårt syfte har vi valt att arbeta med kvalitativa metoder. Vi har genomfört en gruppintervju med personal från hemtjänsten i Kronobergs län, vars strukturer rasade samman under stormen Gudrun. Vi undersökte hur de efteråt återuppbyggde strukturerna genom att analysera olika teman ur empirin. Slutsatser: Osäkerhet, samhörighet, roller, beslutsfattande och rationalitet, är teman som alla är länkade till varandra, till strukturåteruppbyggande och till meningsskapande.

Inom industrin används olika testmetoder för att uppnå hög kvalitet i mjukvarukontrollerade system. Kvalitetskraven är särskilt höga för säkerhetskritiska system t.ex. styr- och reglersystem i fordon. I det här examensarbetet används två analysmetoder (Fault Mode and Effects Analysis och Fault Tree Analysis) för att ta fram ett nytt säkerhetstest för ett broms- och växlingssystem som Scania tillverkar. Det studeras även hur formella metoder kan användas för att ytterligare öka kvalitet ochh tillförlitlighet.

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

The purpose of this study was to examine health promotion and ill-health prevention in the workplaces of the City District Committees in the City of Malmö. More specifically, we wanted to find what types of health problems there were and what kinds of strategies were applied to prevent them. Furthermore, the aim was to examine whether the leaders of the City of Malmö saw any effects of the strategies in use and if so, which. Finally, the intention was to compare our empirical results to previous research in the field of health promotion and ill-health prevention in workplaces. We conducted a qualitative study consisting of semi-structured interviews with five leaders in different levels, two personnel secretaries, two employees assigned to improve the health of the personnel in the City Districts, and one safety representative.

The purpose of this study is to describe and analyze a group of participants (social workers, contact families and the young adults who had been given a contact family as children) and monitor their experience of the intervention contact family and its goals, contents and design. We also wanted to look into what goals and guidelines are available regarding the interventions design and contents. We also looked into parts of the intervention which the participants found most useful for them individually. The method we used in our study was qualitative interviews. We compared and analyzed our results to research made on the subject and the theoretical frame.

This despite the fact that coconut oilcontains of 92 % saturated fat, which strong scientific evidence support raises the blood lipidsand thus increases the risk of cardiovascular disease (3).Objective: To examine the scientific evidence for how blood lipids in adults are affected byan intake of coconut fat compared to an intake of other kind of fats.Search strategy: PubMed and Scopus have been used in the literary search. Keywords usedwere "coconut fat", "coconut oil", "plasma lipids" and cholesterol [MeSH].Selection criteria: Human studies of RCT or cohort type, published since 1983.

Our purposes with this essay was to increase our knowledge about, and try to describe, how it happens when people get involved in gambling and becomes addictive to gambling, and what the way out of a gambling addiction could look like. Our framing of the question was: - How does gambling begin? - How does gambling evolve to an addiction and how does it go forward from there? - How do you leave a gambling addiction? Is there an experience of turning points? We did qualitative interviews with six former gamblers. Our main conclusions were that the initiation to gambling can be very different and still lead to similar effects. There seems to be a strong enticement surrounding the attributes of gambling, which are connected to developing a gambling addiction. The experiences of turning points were very palpable.
