Ikea Loves Wood : Kommunikation vid en CSR-relaterad kris 

Alltfler fo?retag drabbas av kriser som kan ha?rledas till ett oetiskt fo?rfarande. Da?rmed blir det intressant att underso?ka kopplingen mellan Corporate Social Responsibility (CSR) och kriskommunikation. Syftet med uppsatsen a?r att underso?ka hur ett fallfo?retag har kommunicerat vid en kris relaterad till CSR.

Anaerob rening vid StoraEnso Skoghalls Bruk

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Kloridhalter i gran utmed en depositionsgradient för havssalter :

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :

Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour marker in both human and veterinary medicine. TK-1 is an intracellular enzyme involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell cycle dependent and the activity increases markedly after the G1 to S transition in the cell cycle and then declines rapidly in G2. The pronounced proliferative activity in tumour cells result in a higher TK-1 enzyme activity within the cell. The fact that the increased TK-1 activity can be measured in serum makes TK-1 a useful marker in diagnostics of neoplastic diseases and it provides information regarding prognosis and treatment effectiveness. In human medicine a radioactive based test is used to determine the TK-1 serum activity.

Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Klassisk medieanalys - nytt medium : En semiotisk analys av fyra tv-spel

I ett försök av mig att ge spelmediet samma sorts behandling som många andra medier före det har jag valt ut fyra spel inom två olika genrer för en analys av deras handling, karaktärer, estetik och gameplay. Handlingen summeras enligt reglerna för narrativt berättande och en semiotisk infallsvinkel används sedan för att leta efter saker, tecken, som är värda att tas upp för analys i alla fyra kategorierna. Vissa jämförelser görs mellan spelen, främst inom kategorierna estetik och gameplay, först inom samma genre och sedan genrerna emellan för hitta likheter och skillnader i sättet spelutvecklarna har valt att utmana spelaren och göra spelen roliga att spela och hur de har valt att förmedla spelens handling. De utvalda spelen är Capcoms Devil May Cry 3: Dante?s Awakening, Sony Computer Entertainment Americas God of War, Konamis Metal Gear Solid 2: Sons of Liberty och Ubisofts Splinter Cell: Chaos Theory.

Föryngring av tall med och utan skärm på Gotland

Föryngringen av skog på Gotland har historiskt sett varit problematisk under lång tid och i dagsläget används främst markberedning följt av plantering av tall. Förutsättningen för föryngring under skärm samt naturlig föryngring under fröträd som föryngringsmetod har studerats i denna rapport då det råder brist på skriftliga sammanfattningar om dessa båda metoder. Föryngringsmetoderna studerades genom fältstudier på 16 lokaler och intervjuer med verksamma inom branschen på Gotland. Naturlig föryngring visade sig ha viss framgång på norra Gotland samt fungera väl på nordöstra Fårö. Förutom på Fårö visade emellertid föryngring med markberedning och plantering bäst resultat.

Fordrande ord : en kritisk diskursanalys av konsertinstitutioners informativa texter inför konserter

The aim of this master?s thesis is to explore concert institutions? informative texts prior to upcoming concerts ? texts in promotional materials and descriptive texts in programme papers. The thesis is carried out from a critical discourse analytical perspective. The discourse analysis is focusing on finding the texts? messages and it asks the question: To whom are these texts addressed? Theoretical support is mainly taken from Foucault?s theory about the relation between power and knowledge.

Byggkostnader inom mjölkproduktionen - jämförelse av olika stallstorlekar och byggnadstekniska utföranden

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Det obligatoriska skolväsendets pedagogiska strategier i arbetet med elever som har AD/HD. : Pedagoger i en integrerad respektive segregerad undervisningsform berättar och beskriver

The survey aims to highlight and describe how the schools' teaching strategies look like in the work of pupils from the neuropsychiatric disability AD/HD (Attention Deficit / Hyperactivity Disorder). The pedagogical strategies have been investigated in an integrated and segregated teaching method. The study is qualitative in nature where the interviews conducted, first with a student who has been diagnosed AD/HD but also with teachers from each school who is well versed in student teaching and work. The results of the study show that knowledge and commitment about AD/HD is crucial to students' role and function in school. If knowledge and commitment is sufficient for the student teaching tailored to student needs and the risk of misunderstandings occur decreases. Security is a key factor for students who have been diagnosed AD/HD and learning form in itself is no guarantee that students will feel safe. Students have in the two teaching methods stressed that they feel safe at school and with their education and therefore has no teaching method preferred.

Kostråd till föräldrar vid introduktion av fast föda till spädbarn : BVC-sjuksköterskans erfarenheter - en pilotstudie

BVC-sjuksköterskan möter många föräldrar som har frågor om kostintroduktion till spädbarn, en av BVC- sjuksköterskans uppgifter är att undervisa föräldrar i kostfrågor. Studier har visat att föräldrar upplever att de får olika råd från BVC-sjuksköterskor, vilket kan göra föräldrarna osäkra på vilka råd de ska följa. Syftet med pilotstudien var att beskriva BVC-sjuksköterskans erfarenheter av att ge kostråd till föräldrar vid introduktion av fast föda till spädbarn. Fyra intervjuer genomfördes med BVC-sjuksköterskor inom barnhälsovården i Region Halland. Kvalitativ innehållsanalys användes som analysmetod.
