Rabies är en virussjukdom som årligen skördar många dödsoffer i framförallt utvecklingsländer i bland annat Afrika. Spridningen av sjukdomen till människor sker huvudsakligen via hundar och hundbett och flera olika strategier har tillämpats i försök att stävja smittspridning och hindra humana dödsfall. Övervakning av rabiessituationen ger verktyg att planera insatser och utveckling kring förenkling av diagnostiska metoder är under arbete. Övervakning i kombination med vaccinationskampanjer riktade mot afrikanska hundar i syfte att genom flockimmunitet i hundpopulationen hindra humana dödsfall har givit goda resultat. Det är dock viktigt att beakta att olika strategier ger varierande resultat beroende på i vilka miljöer de tillämpas samt att en tillräckligt stor andel av hundpopulationen måste immuniseras.

Purpose: During the last years Real Options have been established in many areas of the day-to-day business. Recent literature also tries to address Supply Chain problems with option theory, since an efficient Supply Chain increasingly gains in importance as a significant competitive advantage. This thesis tries to answer the question, if Real Options can mitigate the costs induced by the Bullwhip Effect as one of the major problems in Supply Chains. Methodology: The authors of the thesis used a deductive approach. Based on a theoretical model utilizing Real Option contracts and under the usage of a randomly created dataset the influence of the Bullwhip Effect on the company?s business and financial structure is examined and subsequently analyzed.

A daily newspaper?s main purpose is to inform its readers without creating noise. Theimportance of the visual presentation is therefore of weight for an effectivecommunication process. This study informs about the importance of typography inthe visual decoding process. The study includes the Swedish newspaper DagensNyheter?s transition from printed media to digital media adapted to an Ipad.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Based on earlier experiences of mathematics and mathematical learning, both as a student and as a teacher, I became more and more interested in how well the publicly accepted opinions about mathematics as an uninteresting, difficult and ?geeky? subject corresponded to reality. What do Swedish pupils really think about mathematics and is it possible to identify any differences in their attitudes based on the pupils? age?From this point of view the following questions were formulated:·What are pupils? attitudes towards mathematics in grades 3, 6 and 9 and how do they conceive their learning conditions?·Is it possible to detect any differences in the attitudes and preferences depending on the pupils? age?The result of this study compares well with previous studies done in this and overlapping fields and indicates that:·Younger pupils tend to have a better liking of mathematics but with increasing age that interest fades out.·Most pupils, without regard to age, consider mathematics to be one of the most important subjects, despite the fact that many pupils also find mathematics difficult and boring.·For pupils of all ages, the teacher is the most important factor in the learning process. Older students have more specific demands on the teacher for knowledge and pedagogical skills.·A high noise level, talking and disturbances in the classroom are the most bothering elements when it comes to learning mathematics.

Changes in the labour market combined with an increased media coverage of managers, have resulted in the rise of a new human due diligence industry. The use of background checks has lately become increasingly popular on the Swedish market and many companies use it as an evaluation tool when recruiting. This study investigates differences in the background screening procedure for recruitment to executive management positions and lower level positions. It also aims to answer why background checks are conducted, using a cultural and a functional perspective. The report takes an abductive approach and data has primarily been gathered through a survey directed to large Swedish companies.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

The present work has been implemented as a literature study aimed to investigate the prevalence, possibly causes and consequences of an eating disorder. In today's modern society individuals are living with a constant reminder from the media about how a person should look and act to blend into the social norms and expectations of the modern society. This literature review has been analysed on the basis of concepts such as identity, gender identity and gender. In addition previous research has been analysed in terms of themes, history, possible causes/risk factors, media, body image and control, depression, shame and guilt as well as culture. The above themes were analysed on the basis of behaviouristic theory and role theory.

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the electric and the credit market. The risk model used is Cost-at-Risk which is usually used by public authorities for analysing the risk involved with national debt.

En svensk version av HINT (Hearing In Noise Test) har tidigare tagits fram för att fastställaförmågan att höra i tal i brus. Målet med den här studien var att se om testet kunde användastill barn och validera det. Vilka av meningarna gick att använda, skulle några utgå och var detnågon skillnad mellan pojkars och flickors resultat?Signalbrusförhållande för 50 % rätt uppfattade meningar mättes på 42 barn (18 pojkar, 24flickor) med svenska som första språk, i åldrarna 6-11 år, för att fastställa medelvärdena i deolika åldersgrupperna och att jämföra resultaten i varje grupp och med en vuxengruppsresultat och validera ett normalmaterial för svenska HINT.Statistisk analys indikerar att signalbrusförhållandet minskar med ålder och närmar sigvuxenvärden hos barn över 8 år. Ingen signifikant inlärningseffekt hittades.

An environmental review has been carried out at FORIA AB, a transportation- and machine service company, to analyze the company?s environmental aspects from the transportation segment. This report describes the essential background and the methods of identifying and evaluate the environmental aspects. It also describes how the work with the environmental aspects often vary between different actors. The design of the ISO 14001 is intentionally broad in order to apply on all sorts of activities and organizations.

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

The starting point for the present study is that the physical environment can enhance the learning processes of children. We want to contribute to more focus being placed on this within library and information sciences. Our main aim is to illustrate how the physical environment can facilitate the learning of children. In order to achieve our aim, we examine a concrete physical environment, namely the children?s department at the main library in Kungsbacka.
