Selenium in Swedish sheep production
Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.
Fosforgödslingseffektivitet i långliggande bördighetsförsök
Rapid population growth and the fact that phosphorous is a limited resource implies that the question regarding an efficient use of phosphorus is of great importance, and consequently,that the phosphorous use efficiency should be as high as possible. The view on phosphorous use efficiency, and how this is calculated, has varied over time. This has had great implications on what type of research that has been conducted, which have resulted in an
inconsistency between the academic?s view on the subject and recommendations received by farmers. The purpose of this paper is to calculate the phosphorus use efficiency in the Swedish long term fertility experiments.
Ekologisk konsumtion : Endast för övertygade?
Bakgrund: Med anledning av Sveriges ökade ekologiska konsumtion så kommer denna uppsats vidare undersöka ekologisk konsumtion som fenomen och hur företag bör arbeta för att på bästa sätt lyckas nå långsiktig överlevnad med just ekologi som grund.Problem: Vilka faktorer är viktiga för företags beslut om marknadsföringsstrategier gällande ekologiska varor, för att nå långsiktig överlevnad?Syfte: Syftet med den här uppsatsen är att analysera och utvärdera konsumentbeteende med avseende på ekologisk konsumtion. Metod: Undersökningen är kvalitativ och kommer att bearbetas utefter en hermeneutisk och systemteoretisk ansats. För att kunna svara till problem och syfte kommer befintliga teorier att användas. Teoretiska perspektiv: Utbytesperspektiv, utvecklingsperspektiv Teorier: Mervärdesteorin, involveringsteorin, marknadsföringsmixen, konsumentbeteende, totalkommunikation, värdekedja och värdestjärna.Empiri: För det empiriska underlaget har sju stycken konsumenter och en branschrepresentant intervjuats.Analys: Empirin har analyserats utefter de faktorer författarna givit som centrala för att svara till problem och syfte. Författarna har efter operationalisering kunnat dela in respondenterna i en matris baserad på involveringsgrad till ekologi. Detta för att göra det enkelt att följa uppsatsens röda tråd.Resultat: Författarna menar att det är involveringsgraden till ekologi, om den är hög, som är avgörande för konsumtion av ekologiska varor.
Återföring av växtnäringsämnen från avloppsvatten till åkermark : en bedömning av intresset för nya näringsrika produkter
Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers.
In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.
LCC-kalkyler i byggbranschen : förutsättningar och tolkning av resultat
Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.

Porösa bländverk. En materiellt ekokritisk studie av Hanna Nordenhöks prosa
In the Swedish author, poet and critic Hanna Nordenhöks (1977-) novels Promenaderna iDalbyhage (2011) and Det vita huset i Simpang (2013) the literary characters are often portrayed asdiffuse shapes with a subtile closeness to other organic bodies, places and times. While the novelsaddress themes such as colonialism and subjects becoming, they also explore the act of narratingthrough letters, journals, photographs and, in particular, fabrication. What emerge are two aesthetic,literary works that, on different levels, trouble our notion of borders between human and more-thanhumanbodies, an issue that?s essential for our understanding of human - environmentalrelationship.The purpose of this thesis is to show how the prose of Nordenhök can be read in the light of theterm porosity, where matter is understood as elastic and open for both creating and de-creatinginteractions. I will argue that the novels contribute to a deepened understanding of the relationshipbetween human subjects and more-than-human matter as elastic, and that they incorporate thisdynamic porosity within the narration itself.
Reducering av produktionstryck i A-linan : Förflyttning av produkt
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Produktionslogistik, effektiviseringav materialhantering
Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog
During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.
Produktnedläggning : Två företags rutiner för avveckling av produkter
Produktnedläggning är ett sätt för företag att få bort produkter som inte presterar tillfredsställande. Tidigare studier har visat att företag med ordentliga rutiner kring produktavveckling har kunnat tillgodogöra sig flera fördelar i form av bland annat bättre lönsamhet och försäljning. Ändå har forskning visat att de flesta företag inte har några formella rutiner för nedläggning av produkter och att produktnedläggning inte ses som lika viktigt som andra produktaktiviteter. Av den anledningen studeras i denna uppsats hur väl utvecklade rutiner två utvalda företag har för avveckling av produkter.Syftet med uppsatsen är att undersöka hur två utvalda företags rutiner för produktnedläggning ser ut. Resultaten jämförs sedan med den teoretiska referensramen samt mellan företagen i fråga för att urskilja likheter och olikheter.Till denna uppsats har en kvalitativ metod använts för att klargöra hur företag går tillväga vid nedläggning av produkter. Genom intervjuer med AB Karl Hedin och Spendrups Bryggeri AB har empirisk data samlats in för att möjliggöra jämförelser företagen emellan samt med den teori som sammanställts. De två studerade företagen har helt skilda förfaranden kring produktavvecklingar.
Neuromuskulär återhämtning efter matchspel hos professionella fotbollsspelare
During football games neuromuscular fatigue occuring following eccentric movements such as sprint, jump and run that occur during games. To avoid injury, overtraining and performance decreases, it is important to know when players are recovered. The aim of the pilotstudy was to investigate physiological changes that occur during football matches and if they affect the recovery pattern after several games in professional football players. The method was divided into two sub-studies in which 12 professional footballers, in substudy 1 performed counter movement jump (CMJ) and drop jump (DJ) from 40 cm and fill out a recovery form for muscle soreness 36 hours before, 12-16 and 60-64 hours after 11 different competetive games. Blood samples were taken on the players in connection with one match to examine the activity of muscle enzyme creatine kinase (CK) and lactate dehydrogenase (LDH) of the players.
