En jämförande studie av kalvuppfödningen på KRAV-anslutna och konventionella mjölkgårdar :

In order to investigate if the KRAV-regulations have any effects on the health and welfare of calves, KRAV-affiliated farms were compared to conventional farms with respect to calf management and outcome. The dairy calf has had a low economical impact during history. Even today the value of the calf is low and a lot of calves have a poor health status. The calf breeding is built on tradition and on the fact, that cheap antibiotics have made it possible to ignore, the recommendations about good hygiene in the calf?s environment.

Use of feline TK1 as a biomarker in disease monitoring

Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis. TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.

Flickstaden : Flickbokens diskurs och sadomasochism i Agnes von Krusenstjernas Ninas dagbok, Helenas första kärlek och Fröknarna von Pahlen

The object of this essay is the Swedish author Agnes von Krusenstjerna's novels Ninas dagbok (The diary of Nina) and Helenas första kärlek (Helena's first love) as well as the cycle novel Fröknarna von Pahlen (The misses von Pahlen). The purpose is to explore her use of the discourse of girls' fiction, which I analyse by the depiciton of women's sexual awakening, and her depiction of sadomasochism. The theories of Elaine Showalter, Jacques Derrida, Michel Foucault and Judith Butler are used.Women's sexual awakening is depicted similarly in the novels but more explicitly in Fröknarna von Pahlen. In Ninas dagbok and Helenas första kärlek there is an eroticization of dominance and submission, which is not explicitly sadomasochistic. In Fröknarna von Pahlen, sadomasochism is explicitly described as a "perverted" sexuality and reveals the inequality in the violent sexuality, which is described as "normal".

Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.

This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.

Folkbibliotekarier och nya medier: en diskursanalys av folkbibliotekariers inställning till nya medier

The aim of this Masters thesis is to examine librarians opinions about media. Four questions are asked: What kind of different attitudes to new media has librarians had? How is new media discussed in relationship to each other in the debate? What mechanisms and underlying causes control the discourse for new media in public libraries? Does the discourse change over time, in that case, how? The theoretical background is theory about moral- and media panic and popular adult education. The media panic theory includes the idea that the same reaction occurs every time a new media is introduced. The theory about popular adult education is that the public need to be cultivated.

Kommunal värdering av nyttjandetider: Hur uppnår kommuner rättvisande avskrivningstider på materiella anläggningstillgångar?

Rådet för kommunal redovisning utkom 2006 och 2009 med nya rekommendationer för hur kommuner ska värdera sina anläggningstillgångars nyttjandetider. Syftet med detta arbete är att öka förståelsen för hur kommuner värderar och fastställer materiella tillgångars nyttjandetider. Arbetet syftar till att identifiera och beskriva kommuners värderingsmetoder, arbetsprocesser samt att utveckla en modell för fastställande av tillgångars nyttjandetider. Arbetets data är insamlad genom två delstudier där semistrukturerade intervjuer användes som datainsamlingsmetod. Insamlad data analyserades med hjälp av teorin om ansvarsskyldighet, agentteorin, teorin om förvaltarskap, institutionell teori samt Life cycle costing teorin.

Trygghet och säkerhet i offentlig stadsmiljö :

To thoroughly think with safety and security in mind is an important issue in planning of public city spaces. Spaces intended to be available to all inhabitants of a city should have a welcoming appearance. Unfortu-nately, this is not the situation in many pedestrian walkways, parks and such spaces, possibly due to lack in safety and security. This master thesis intend to examine questions at this issue ? what makes you feel safe and what causes insecurity in public city spaces. The safety aspect treats the human psychological and sociological ways of perceiving her milieu and other humans in it, and how the physical shape of her surroundings can affect the sense of safety.

Framtagning av primärkonstruktion till nytt cykellås

Cykelstölder är ett stort problem i dagens samhälle. I Sverige polisanmäldes 65 700 cykelstölder under 2011. De cykellås som finns på marknaden kan på ett eller annat sätt brytas upp och efter det är cykeln fullt brukbar. Examensarbetets uppdragsgivare hade idéer om ett nytt cykellås som förhindrade cykelns brukbarhet efter uppbrytning av låset. Idén ledde till ett samarbete med uppdragsgivaren, mig och teknikkonsultföretaget, Cross Design.

Optimerad lagerhantering

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

Kvicksilver i skogsmark

I mer än hälften av Sveriges sjöar innehåller gädda en kvicksilverhalt som övergår Food and Agriculture Organization?s (FAO) rekommendationer. Det kvicksilver som finns lagrat i svensk skogsmark är ett resultat av antropogent nedfall. Studier visar att kvicksilver utlakas vid skogsbruksåtgärder på hela skogsmarken som en följd av förhöjd rörlighet av dissolved organic carbon (DOC). En ökad metylering av kvicksilver sker vid vattenmättade, syrefattiga förhållanden där det finns tillgång till organiskt material.

Utlandsetableringar & aktieägares förmögenhetsvärde : En eventstudie om utlandsetableringars påverkan på aktiemarknaden

The aim of this study is to examine the market reaction when information about a company?s foreign direct investment is announced and how that affects the shareholder?s value. Also of interest is whether the market reacts differently depending on which country the investment is established in and which mode of entry is used. This will be achieved by using an event study approach. The selection that was used consisted of 206 companies registered on the Nasdaq OMX Nordic homepage, which had during a time period stretching from 1999 to 2009 established a foreign direct investment in the regions BRIC, Europe or the USA using the mode of organic growth, joint venture or acquisition.

Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :

Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden. The purpose of the study was to attain a greater knowledge about CCF practices.

Samband mellan digivning, avvänjning och mjölkens sammansättning med fokus på mjölkfett

Sammansättningen och kvalitén på mjölken som produceras är betalningsgrundande och därmed är det viktigt ur en ekonomisk synvinkel att producera mjölk som håller en hög standard. Syftet med denna litteraturstudie var att undersöka om samband finns mellan typ av digivning respektive avvänjning och mjölkens sammansättning. Fokus ligger på mjölkfettet samt fettsyrorna. De produktionssystem som tas upp är begränsad digivning och artificiell uppfödning. Begränsad digivning innebär att avkomman får gå med moderdjuret vissa timmar av dygnet fram till en senare avvänjning jämfört med artificiell uppfödning där avkomman skiljs från moderdjuret strax efter förlossningen.
