Analys av haptoglobin i bovint serum med surface plasmon resonance biosensorteknik :
The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.

The assignment is issued by Scania Maintence AB seeking a new approach to detect power changes in their industrial processes. The work has taken place at Ångströmslaboratoriet and tests have been performed at Scania AB Södertälje.Today?s society consumes enormous amount of energy. In both economically and environmental view, it is important that the processes are effective, with high power factor. There are many ways to measure power in the industry, what they all have in common is that the installation is advanced, requires time and planning.
Den iranska nationen - Vi och de i kärnkraftskonflikten
Den här uppsatsens syfte är att undersöka vilken iransk identitet som skapas av landets ledning och på så sätt bidra till förståelsen av den iranska politiken. Frågeställningen är: "Hur ser den identitet ut som konstrueras av det iranska ledarskapet genom deras offentliga tal gällande kärnkraftsfrågan?". Frågan besvaras utifrån ett konstruktivistiskt perspektiv och med Laclaus och Mouffes diskursteori som metod. Analysen består av en kartläggning av ekvivalenskedjorna för Vi, "Den iranska nationen", och De Andra, "Irans Fiender".
Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3
A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.
U-137 svenskt politiskt och militärt agerande under kris
This bachelor thesis deal with the Soviet submarine U-137 and it's grounding inthe Swedish archipelago outside the city of Karlskrona and one of Sweden?slargest naval-bases. The actions that took place in October 1981 were specialbecause of the clear violation of Swedish territory. When the Swedish authoritieslater suspect nuclear armament onboard the crisis gets worse. In the thesis wehave examined the Swedish politicians and military and their behaviour duringthe crisis.
Sjöingenjör : Möjligheternas Yrke
Kärnkraften ser vi som ett miljövänligt och bra alternativ för framtiden. Därför kändes det intressant att undersöka om vi som blivande sjöingenjörer har en framtid där efter våran karriär till sjöss. Syftet med detta arbete är att få ökad insikt om vilka teoretiska kunskaper, praktiska och personliga egenskaper som gör sjöingenjören attraktiv i ledande befattningar vid kärnkraftsverk. Datainsamlingen skedde med hjälp av en enkätundersökning och en intervju. Undersökningen skickades ut till Sveriges samtliga kärnkraftverk och intervjun gjordes med en anställd på ett utav dem.

Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power
Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..
Diplomati med klyvbar kärna - en kvalitativ studie av den ryska diplomatins grundval
AbstractThe purpose of this thesis is to analyse the basis of Russian diplomacy, and by doing that develop the analytical instruments available, in order to improve the comprehension between the parties in negotiations. Descriptions of the national characteristics of Soviet and Russian diplomacy are made by an analysis of memoairs and other examinations of their negotiating behaviour. To ensure the result of the characteristics two case studies of the non-nuclear proliferation negotiations are made, followed by a comparation between the Soviet and Russian diplomacy. From these results, I analyse the groundworks of russian diplomacy, using three theories about how ideology, national identity and prevailing self-image can affect the national negotiating behaviour. The results show that there have been changes in only some parts of the negotiating behaviour and that there is a need for all three theories to explain different parts of the complex system of Russian diplomacy which is based on the plurality of culture, ideology, language, ideology and history..
Den ena boplatsvallen är den andra lik? : Miljöarkeologisk intra-site studie av boplatsvallar vid Lillsjön, Anundsjö sn., Ångermanland
Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements, used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
Reduktion av organiskt material med MIEX®
Uppsala- och Stockholmsregionerna använder Mälaren och dess tillflöden som dricksvattenkällor. I Mälaren varierar halten organiskt kol från år till år och kan medföra problem såsom oönskad lukt, smak och färg vid dricksvattenrening. Det kan även vara problem med avseende på bildning av desinfektionsbiprodukter (DPB) och transport av toxiska ämnen med dricksvattnet. I takt med den globala uppvärmningen kan dessutom halten av organiskt kol i Mälarens ytvatten och dess tillflöden öka. Det medför att halten av organiskt material även skulle öka i vattenverkens råvatten och det skulle i sin tur uppstå svårigheter att hålla dagens gränsvärden.
Normering av nasaleringsvärden uppmätta med nasometer hos barn i fyra- till femårsåldern i Linköping
The Nasometer is a non-invasive acoustic measuring instrument that quantifies the ratio ofnasal resonance in speech. It can be used as a complement to perceptual judgment of speech impediments, for example, in patients with cleft palate and velopharyngeal insufficiency. Inorder to determine if a nasalance score is abnormal, it must be compared to norm data. The main purpose of the study was to collect reference nasalance scores in children between fourand five years of age in Linköping. An additional objective was to compare the results tonorm data collected in Umeå.
Myndigheten och den ensamstående föräldern. En studie av ensamstående föräldrar med barn och deras behov
In this study we describe the needs of lone parents and how the authorities fulfill these needs. The needs contain both economic and social aspects, such as the access to an employment, childcare and the possibility to social activities. For the lone parents being able to work the childcare provision must improve and be available in a greater extent during non-traditional working hours. It is also required that the housing benefit ceiling is increased so that the parents may work more hours without risking the loss of the housing benefit. The statistic about the housing benefit which we present shows that many of those with a low income are lone parents.
