"där jag skulle liksom hitta ..allting..."; mötet mellan privatforskare och Kungliga Biblioteket
The purpose of this paper is to investigate and analyse the private researchers encounter with the Royal Library, national library of Sweden. The main focus is on answering the two questions: who is the private researcher and what is his/her impression of the Royal Library? These questions are answered from the vantage point of the following theoretical perspectives: library anxiety, Bourdieu, library architecture, gender studies and service management. The methods used are qualitative interviews, and textual analysis using the printout of these taped interviews along with notes and an earlier user study as material. The conclusions are that barriers with staff is the most frequent factor of library anxiety in the private researcher at the Royal Library, and mechanical barriers the least frequent.
Njurfunktion hos hypertyreoida katter : en jämförelse mellan serumkreatinin och serumcystatin C
Hyperthyroidism and chronic kidney failure (CKD) are common diseases in older cats. It can be difficult to evaluate kidney function in cats suffering from both conditions simultaneously. In the daily clinic serum creatinine is the analysis of choice when evaluating kidney function and secondary glomerular filtration rate (GFR). This marker does not, however, detect kidney damage until about 75 % of the function is lost. There are several other techniques available when investigating GFR but none are readily available for the small clinic.
Fastställande av referensintervall för fibrinogen i plasma hos friska föl :
Establishing a reference interval for plasma fibrinogen in foals
Fibrinogen concentrations were analysed in EDTA preserved blood plasma samples from 34 thoroughbred foals born in 2001 and 2002 at one stud farm. The foals were between 0 and 240 days old at the time of the sampling, and there were 19 fillies and 12 stallions in the group. The foals were examined for clinical symptoms of disease and their body temperature was measured before blood was sampled from the jugular vein. From totally 156 blood samples, 31 were selected as originating from clinically healthy foals, and used to determine a reference range for thoroughbred foals. Samples originating from foals showing clinical symptoms of disease or an abnormal body temperature at the time of sampling, were classified as coming from unhealthy animals.
Marknadspsykologi : och effektivitet på aktiemarknaden
Den finansiella teorin om effektiva marknader och rationella investerare har allt oftare blivitifrågasatt i takt med att marknaden utvecklats. Realtidskurser, rekommendationer och ryktenpräglar många investerares beslutsfattande och tvingar kanske fram ogenomtänkta beslut.Genom att diskutera och analysera hur riskbenägenhet påverkar investerarnasavkastningsmöjligheter ville jag se om detta öppnar upp möjligheter för så kallade noisetraders och arbitrage traders. Vidare diskuterar jag om marknadspsykologiska effekter kantänkas påverka börskurser över tiden eller om arbitrage traders fungerar som försvarare av deneffektiva marknaden och handlar bort anomalier som de psykologiska effekterna ger upphovtill. Slutsatsen av min diskussion är att investerare inte alltid handlar rationellt och attriskbeteendet hos investerare varierar med deras förväntningar, då riskbenägenheten kan ökavid förlust och minska vid vinst..
Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter
Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
N?r ekonomin stryper En kvalitativ studie om Europeiska unionens sanktionsf?ring i f?rh?llande till ideologiska v?rden och interdependens
This thesis examines the European Union's sanctions policy regarding human rights and
interdependence. Previous research has discussed whether sanctions are effective or result in
desirable outcomes. This paper aims to take a step back and understand motives by analyzing
consistency in the EU?s decisions to impose sanctions. The question is relevant because formal
justification can be used to cloak actual motives, and by examining actual decisions, the analyses
shed light on motives.
Simulering av översvämningar i Nedre Dalälven
Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

650 stycken citroner, 120 stycken påmerantzer, 200 stycken apellisiner : Vägledning till tullarkiven på Landsarkivet i Uppsala
The organized and controlled form of collecting consumption taxes and toll from the import and export trade goes back to the 17th century in Sweden. The customs administration and procedure were regulated by royal announcements, and the majority of the documents found in the customs archives represent thus records stipulated by such notifications. The customs archives can be used for research on several levels; the announcements reflect currents within both the domestic and foreign politics, while the account lists for financial statistics portray the extent of the trade. The various lists of compilation can be further used to follow for instance the development of different units of measurement, the expansion of tax rates, the value of trade goods or the changes in monetary units or systems. The diaries, architectural plans of the customs offices and maps of the toll areas place the customs officials and their work within the local scenery.The thesis focuses on archives deriving from customs located at harbors and on the Swedish-Norwegian border in the county of Dalarna.
Effekt av olika kvävegödselmedel på utvecklingen av klumprotsjuka i salladskål (Brassica rapa ssp. pekinensis)
The price trend on rapeseed the latest years has led to an increasing interest to grow the crop among many farmers in Sweden. The price trend has resulted in more than a doubling of the oilseed area since the early 2000s. For many farmers it is an advantage to increase cultivation of rapeseed because of the high proportion of cereals in the crop rotation on many farms, but it is not just benefits. The risk of the fields being infected by clubroot increases within frequent rapeseed cultivation and it often leads to subtantial economic losses. Clubroot is caused by Plasmodiophora brassicae that is a soilborne pathogen in genus Protozoa and its resting spores can be found in the soil for up to 18 years.
Överföring av digital video via FireWire
Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

Ett digitalt vågfilter av Richardstyp har implementerats i en FPGA på ett utvecklingskort. Sampel kan skickas till filtret och mottas från filtret via serieporten på en dator. Metoden som användes är att en modell av filtret konstruerades i Simulink. Filtret har modifierats med avseende på skalning, brus och stabilitet. VHDL-koden till filtret genererades i Simulink genom att bygga modellen av Xilinx Blockset.
Digital delaktighet i Sverige : Om att inkludera alla i framtidens samhälle
Almost all Swedes today have access to the Internet, if not through the home then via the library or work. Despite this, around 20% of the population stand outside the information society in that they lack in knowledge, assistive usability tools or positive attitude towards technology and its influence on society. The main factors influencing the digital divide in today's society are age, disability and education, while the main reason for staying outside seems to be disinterest.The question about digital inclusion is important as we now stand on the breaking-point between a society where the industry has had a prominent position for private as well as national economy and a digital society where access to the Internet is no longer about prestige, but where significant differences between users' knowledge levels can create a power gap. Gaps in access and use not only reflects already existing socio-economic conditions, but can also maintain and enhance these.It is crucial for the future expansion of Internet usage how today's non-users feel about becoming users. To understand what underlies the motivations not to use computers is one of the keys to get non-users to embrace becoming users.
Hyperglykemi hos kor med löpmagsdislokation :
The main interest of this study was to investigate whether there is hyperglycemia or hypoglycemia in cows suffering from abomasal displacement and to evaluate the effect of transport on blood glucose. Thirty-six cows with left- or right-sided abomasal displacement were included in the study together with 17 cows with other diseases for comparison. Fifteen cows with abomasal displacement and 7 cows with other diseases were sampled before transport.
One third of the cows with abomasal displacement had hyperglycemia when the transport effects were corrected for. Separating this group in left- and right-sided abomasal displacement we found significantly higher blood glucose and insulin levels among cows with right-sided abomasal displacement. An explanation for this difference may be a strong stress response secondary to the right-sided dislocation.
