Milk ejection in dairy cows can be inhibited if oxytocin is not released from the pituitary gland. The problem with inhibition of the milk let down is not new, but has recently regained interest. It is observed during different types of emotional stress, for example when cows are moved to an unfamiliar environment, during oestrus, changing from suckling to machine milking or when being milked for the first time. The aim of the study was to examine the extent of cows with disturbed milk ejection in Sweden. A survey was sent out to 1000 dairy farmers in order to collect data about herd size, housing systems and routines at calving and milking.

Companies and special interest organizations pays multiple millions each year in order to reach out with messages about that their products are biggest, best and most beautiful. The publicity happens among thing like TV, in brochures, on the Internet andin newspapers etc. places. This means that consumer permanently becomes affected of publicity, and is thereby in an exposed situation. Around the EU, the border of what to consider undue or not, have been in different levels.

One could argue that the most discussed topic in finance is whether or not it is possible to ?beat the market?. Even though many people claim to do this, there is little evidence to support the idea that one can consistently beat the market over a long period of time. There are indeed several examples of investors who have managed to outperform the market consistently for a long time, but the efforts of these individuals or institutions could by many be considered to be pure luck.One of the many strategies that have been evaluated by several researchers and is said to generate a risk adjusted return greater than that of the market, is one based on the P/E-effect. This strategy is based on the financial ratio P/E ? price divided by earnings ? and used by constructing portfolios consisting of stocks with low P/E ratios.

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening lead times and how these methods effect the lead times in research and development.

This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.

Recently, there have been intense discussions about the humanities and their role in society. Internationally, as well as in a Swedish context, the humanities have been regarded to be in a state of crisis. However, these discussions usually demonstrate a lack of historical perspectives based on thorough empirical research. The notion of a crisis needs to be historicized.In this study, a case is being examined where the relationship between science and society was renegotiated. In the context of World War II, a discourse has been identified in a borderland between science and politics through an analysis of Swedish journals and anthologies during the time period 1937-1947.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

Heart failure is a condition where the heart is incapable of providing adequate blood supply to different organs in the body. The underlying causes of heart failure is some kind of disorder in the heart function, and require careful diagnostics. The basic symptoms that arise from heart failure is difficulty in breathing, that aggravate when lying down, and fatigue. The patients? symptoms and impaired quality of life can be in different stages depending on the severity of the heart failure.

In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.

Face-to-face communication is always complemented with non-verbal signals that give us clues as to how a message shall be interpreted, but as communication is moved online the possibilities to express oneself becomes more limited.This paper focuses on the instant messaging client Windows Live Messenger and three of the non-verbal functions that it provides (nudges, winks and emotes). The purpose of the paper and its underlying study is to compare the senders' intentions with the receivers' conceptions when it comes to these functions.The study was done as a questionnaire with two different versions of the questions, one looking at the senders' intentions and the other at the receivers' conceptions.The results were then compared in order to look for tendencies. The results showed that the most common intention among the senders was also the most common conception among the receivers, but that the rest of the attitudes didn't match at all. The functions that are supposed to help the conversation flow often create ambiguity instead and lead to vagueness, misconceptions and annoyance..

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and thus the stress for the animal and also in order to increase the possibility of starting relevant treatment early on. The aim of this pilot study was to determine whether Serum Amyloid A (SAA) could be a measured in blood samples from bottlenose dolphins (Tursiops truncatus), Asian elephants (Elephas maximus) and South American tapirs (Tapirus terrestris). SAA rises to its maximum about 24 hours after the introduction of an inflammatory agent in companion animals. This also correlates with the estimated time it takes for animals at Kolmården Wildlife Park to be examined and having blood samples collected after being observed as sick. The study also evaluated whether the Eurolyser SOLO, using a turbidometric immunoassay (TIA) developed for human diagnostics, could be used for such analysis. This pilot study was a retrospective analysis of SAA in convenience sampled frozen serum, collected from dolphins, elephants and tapirs.

This master thesis has been written in collaboration with Science Park Jönköping and is based on a problem related to corporate innovation. Science Park Jönköping believes that there is an untapped potential in existing industry in the form of ideas that are never commercialized. These theories are also supported in the research in which other authors have perceived that the ideas and inventions which do not belong to the core business risk ending up in drawers. If more of these ideas could be spin-offs or other forms of enterprise instead of staying in the drawers it would lead to growth, both for companies and for the society in large.The purpose of the thesis work is to, based on the case Science Park Jönköping, analyze how science parks and incubators can support the commercialization of ideas that derive from industry, who otherwise had been left lying. The work began with a mapping of the Science Park Jönköping operations and the skills they possess, and then other initiatives that aim to commercialize more ideas from companies were examined.

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

This is a study with a qualitative approach and a social psychological perspective. Our purpose is to describe and analyze authority officials descriptions of individuals with a social disability and their perception of how the interaction in the encounter with its implementation. We are interested in how they experience their power as authority representatives. The following issues are highlighted.? How do people in authority describe individuals with a social disability?? What is the authority officials view on the interaction in meetings with individuals with a social disability?? How do authority officials experiencing his or her position of power in relation to the meeting?Our results are based on semi-structured interviews with five persons in authority, which is active in Insurance and Employment Service in Örebro County.
