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.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases theFrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

A nonsense mutation in the DMRT3 gene has been shown to have a large impact on pattern of locomotion in horses. Horses that can perform several other gaits in addition to the normally occurring gaits, walk, trot and canter, are often hetero (CA)- or homozygous (AA) for this nonsense mutation. Horses that only can perform walk, trot and canter are often homozygous for the wild-type gene (CC). For example the Icelandic Horse is a gaited breed. Five-gaited Icelandic horses can perform both flying pace and tölt, except for the normally occurring gaits, walk, trot and canter, and are often homozygous for this nonsense mutation (AA).

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

This study aims to analyse how sex and sexuality are presented in the Buddhism and Hinduism chapters of religious studies textbooks for upper secondary school. The chosen textbooks are all linked to the new curriculum Lgr 11 which was implemented in the Swedish school system in the spring of 2012. The textbooks were analysed by using two methods; content analysis and discourse analysis. Content analysis was used to examine with which Frequency sexes and sexualities appear in the textbooks, while discourse analysis was used to find what discourses surround the two concepts. The discourse analysis used two theories in order to contextualize the several discourses about sex and sexuality.

Media has a big actuating power over the public opinion. The image of reality that media choose to reproduce will affect the recipient view of reality. The case about Thomas Quick and its associated news coverage has been used as an example to illustrate the problematization regarding media imag-es and media framing attempt. The purpose of this essay was to illuminate how daily and evening newspapers works with various framing methods.The theoretical framework for this essay will discuss the media framing theory and its ramification attribute framing theory. This laid the foundation for the research question.

The horses? natural behaviour is easier to satisfy in a loose-housing system than housed in a traditional box. Law?s and science suggest that we should house horses in loose-housing, which improve the horse possibility to perform natural behaviours, to interact socially with other horses and to have more possibility to movement. It?s more timesaving in a working population aspect and a economic gain in materials. We noticed that it?s different opinions about what people in the horse society thinks about having youngsters housed in a loose-housing system.

Our employer Camatec Industriteknik AB gave us the assignments to increase theirs range of versions on Camcoil that is their own patent product. Camcoil is a capstan system that is used when steel band fabricated. Exist for example in production lines their steel band should be annealed. Our goal with this work is to come up with a completed production basis on a Camcoil for heavy industry. The basis should contain calculations, 3D-constructions, drawings and cost proposal on manufacturing and detail purchase.Demands on this project:1.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

In Sweden, harvesting pre-commercial thinning (PCT) stems for energy purposes is a interesting way of financing the high cost of preparing dense stands for a profitable first conventional thinning. This concept can be labelled bioenergy thinning. The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 stems/ha, and measured on average 4,6 cm Dbh and 7 m tall. Even though the driver was well experienced with the machine, the stand in question was the first one that he ever thinned in this manner. Nevertheless, the driver strived to accumulate as many stems as possible during each crane cycle and chose to cut taller stems in half so as to make the handling and forwarding of the harvested stems easier.

Humans attitudes towards different animals are very complex were culture, genetic, psychology and evolution are some of the factors that influence. The order of animals that can provoke the most intense and extreme attitudes, both positive and negative, are the carnivores. Wolves are a constant debate in Sweden and even though a big part of the population are neutral towards the wolf, a clear friction of the attitudes can be seen. Some factors that have been seen to influence the attitude are age, education and the size of the hometown. The aim of this study is to investigate whether outdoor activities, time spend in rural areas, and time spent in a weekend cottage, also correlate with attitude towards wolf.

Canine dilated cardiomyopathy (DCM) is a disease with high morbidity and mortality and with a high prevalence in certain breeds. Predominatly large breeds are affected, such as Great danes, Newfoundlands, Deerhounds and Dobermanns. One exception is Cocker spaniels, where both American and English Cocker spaniels are affected in a quite high Frequency. Cardiomyopathy is characterised as a disease that affects the myocardium and gives an impaired heart function. To diagnose DCM following criteria have to be observed: 1. Dilation of the left ventricle. 2. Reduced systolic heart function. 3. Increased sphericity of the left ventricle. To be certain of the diagnosis, alternative reasons for the symptoms such as lung- and heart diseases with other etiologies have to be excluded Two different types of DCM have been found upon histological examination.

When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.

The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.
