Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

"Den stora stygga vargen?" : En argumentationsanalys om vargens moraliska värde i vargdebatten

The purpose of this paper is to see which ethical content arguments have in the debate about wolfhunting, particularly with regard to the Svensk Jakt respective Tidningen Djurens Rätt's arguments. The method used in this paper is the analysis of arguments in which I investigate the pro and contra arguments of the four authors of the articles that I have chosen to study. I will avail myself of theories from Carruthers and Franklin. Analysis shows that the authors of the Swedish hunting above all have a ecocentric view of the wolf where it is an instrumental value for the ecosystem, and the authors of Djurens Rätt's has especially a biocentric view of the wolf where it may be an absolute value, but they can also extend to the that the wolf has instrumental value in the ecocentric perspective. The discussion has shown that Djurens Rätt's and Svensk Jakt has a common position that is an ecocentric perspective where the wolf has instrumental value, even though they believe that different actions are different law to protect the species and the ecosystem..

Ger ministerstyre en effektivare krishantering? Lärdommar från tsunamikatastrofen 2004

After the tsunami disaster in December 2004 many arguments were heared that one oft the major reasons behind the poor Swedish effort connected to the evacuation and health care of the Swedish citizens in Thailand right after the incident is the Swedish model with independent government authorities. By comparing the constitution, the political decision making tradition by the ministers and the handling of the catastrophe in the tree Scandinavian countries Denmark, Norway and Finland, plus analysing the behaviour of the Swedish foreign and prime minister from a rational choose inspired individual decision making theory the research shows that there is no proof that a constitutional change in Sweden into the traditional model with government authorities controlled by the ministers alone would led to a more effective crisis handling by the government due to crises concerning Swedish citizens out states. Although the research shows that the constitution and the tradition of decision making in the government provides the basic condition of the ministers individual rational decision making.

Stora och mäktiga sanningar : En studie av några populärvetenskapliga framställningar av Charles Darwins idéer i Sverige 1859-1909

Uppsatsen undersöker några svenska populärvetenskapliga framställningar av Darwins idéer under halvseklet efter publiceringen av On the origin of species. De publikationer som studeras mest ingående är Ny illustrerad tidning och Verdandis småskrifter. Med hjälp av Ludwik Flecks vetenskapssociologiska tankar, jämte ett antal andra perspektiv på polulärvetenskapens form och funktion, resonerar jag om populariseringarnas folkbildande och stundtals politiska syften och sätt att presentera en omstridd teori som ovedersägligen sann. Uppsatsen innehåller också en översikt över populärvetenskapens historia i Europa och Sverige..

Om anhöriga och relationers betydelse vid psykossjukdom i det psykoterapeutiska arbetet

The purpose of this study is to better understand patients suffering from psychotic illness along with their family members, and to identify treatment factors that have been helpful for these patients and their families by investigating how their relationships have been affected by treatment. In this way, treatment methods can be put in a theoretical context, treatment efforts can be clearer, and the therapist can develop professionally.The research method used is a semistruktureted interview conducted with tree patients and their families. One conclusion one can draw in the successful treatment with psychotic patients is strongly based on the therapist?s ability to build a safe and secure treatment alliance with both the patient and his family members. Meeting with patients in situations outside of the therapy room have been of great importance for the therapeutic process.Important themes for recovery that come forth during the interviews with the patients are the quality of the therapy session as healing factor.

Formulering och provning av en ny typ av sågkedjeolja

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder

This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).

Operationssjuksköterskors beskrivningar av att arbeta med WHO:s checklista för säkerhet vid operationer

Background:In Sweden there are several thousand surgical procedures performed every day. The treatment is expected to be efficient, profitable and safe. Despite that, complications occur in 3-16 % of the surgical procedures. To prevent this, WHO has developed a surgical safety checklist containing safety issues to give the surgery team an opportunity to a last control that everything has been properly done. The profession of the surgical nurse focuses mainly on patient safety especially regarding hygiene and sterility.Aim: The aim of the study was to investigate and describe the perceptions of the perioperative nurses regarding WHO: s surgical safety checklist.Method:To test the suitability of the method a pilot study was performed where tree operating room nurses were interviewed and the data was analyzed using qualitative content analysis.Results: Four categories emerged; Increased patient safety, enhanced team spirit, good planning, stronger professional role.Discussion: The result from the study showed positive perceptions regarding the surgical safety checklist, a fact known from earlier research.Conclusion: The results of the pilot study showed that surgical nurses had good support in their work when the surgical safety checklist was used..

Värdering av katastrofers miljökonsekvenser

When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.

Att restaurera forna tiders beståndsstruktur : ett exempel från Jämtgaveln

In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale. The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.

Så långt inuti, näst intill borta

Through wing pattern, posture and movement, a harmless moth of the family Brenthia imitates an eight-eyed jumping spider. When an octopus of the species Thaumoctopus mimicus sense danger it can alter its appearance to that of a venomous sea snake. They are both drawing attention to themselves. Nevertheless, and because of this, they are protected. The mechanism is called mimicry.

Evaluation of a method for determinationof glutathionereductase activity inerythrocytes

Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.

Svansbitning hos grisar, arv eller miljö?

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Skanska and their strategic Polish suppliers: Analysis of the buyer- supplier relationship against the interplay of pricing strategy, supply chain policies and culture

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

Det splittrade subjektet : En analys av Marx filosofiska grund genom Kritiken av Hegels Rättsfilosofi

In the Philosophy of Right Hegel develops the concept Sittlichkeit (Ethical life) that represents Hegel´s view of how the State should be constituted. In Critique of Hegel?s ´Philosophy of Right` Marx provides a critical so called ?Prussian? reading of Hegel as ultimately a defense for the Prussian empire of that time. The study focuses on a close reading of the chapter on the state, which includes the paragraphs 257-313 in the Philosophy of Right. It examines how Marx?s philosophy developed from this Criticism including some of his basic concepts, notably Gemeinwesen and Gattungswesen, that he takes over from Hegel and includes in his own theories of human alienation.
