Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

In 1930 a new library reform came into force, which in reality was the beginning of the modern Swedish library. The purpose of this reform was to take measures to promote efficiency, for example to increase library co-operation. The Government grants were at the same time raised considerably. However, as early as in 1930, but especially the following year, the depression hit Sweden. The Government reduced the grants until the first half of 1936.

A central discussion within society and businesses today, is the change of generations in the business market which occurs within the upcoming years. A change of generations is unavoidable and a natural step in business. The challenge of the forthcoming reform is the large number of people leaving the labour market and the grand entrance of new labour; Generation Y. The characteristics of Generation Y differ from the older generation which enhances the challenges for the businesses to attract a new workforce. It may also be necessary for the organisations to adapt to the younger generation.

In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

In Sweden the social assistance from a historical perspective, has been a part of the social legislation, since the 18th century. In that time called poor relief. Through the centuries this has established the social assistance we have today. With focus on the child, we have attempted to illustrate how the social workers consider the child perspective when they are dealing with the social assistance. We wanted to get a view of how the social worker reasons about needs the children have and how they can see that the benefit has been provided for.

Epilepsy is a common neurological condition in dogs, being a common reason for death in the statistics from the insurance company Agria in Sweden. Among the different types of epilepsy, idiopathic epilepsy (IE) is the most common and is characterized by the fact that a veterinary examination does not reveal a cause for the seizures. This study has been conducted through studies of medical records and interviews with dog owners. From a total number of 103 dogs that were neurologically examined for seizures, 42 dogs met the inclusion criteria, being classified as having idiopathic epilepsy. When the study was performed, 28 dogs had died, while 14 were still alive.

A new curriculum, entailing news for teachers as well as students, was implemented in 2011. Among other things History has been given a more prominent position in that every student will now study the subject. Can this decision lead to history being used more in the future?The aim of this thesis is to study the new curriculum, Gy11, as well the Lpf94 and Lgy70, based on Klas-Göran Karlsson´s typology where the use of history is divided into seven different categories. I will analyze the curricula, looking at what different uses of history that can be discerned as well as what changes have been made over time.

In the curriculum for Swedish pre-school the focus is mainly on five concepts. These are care of the children, learning, influence, rearing and security. These concepts are to characterize the activities of the pre-school in Sweden.Back in time the focal point of pre-school activities for young children was mainly on security. The learning part became more prominent as the children grew older. When speaking to teachers and parents I do sense that some believe this is the case even nowadays.

Problem: The Swedish wage-setting has changed since the time for the breakthrough of the industrialism until today. Before that, wages often consisted of perquisites or goods that could be exchanged against other goods. Rural people were often self-sufficient. In some cases the farmer owned the land, in other cases they where tenants. At the time for the breakthrough of industrialism the demand for similar labour were increased.

Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested.  The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.

The purpose of this thesis is to investigate and analyze existing law concerning joint owner-ship in agriculture and forestry businesses. Joint ownership often arises through a succes-sion of ownership, therefore we will go through the most useful methods.Even if the owners of agriculture and forestry businesses are getting older, the numbers of succession of ownerships are still low. A succession of ownership is important to plan and its time is demanding. Often it takes three to five years for the completion of a succession of ownership. Therefore, owners must start their planning in time and think about what is to come of their business.

In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.

Den svenska skolan har haft elever som bedömts vara i behov av särskilt stöd sedanfolkskolan infördes 1842. Hur denna undervisning bedrivits eller varit utformad har sett olika ut under olika tidsperioder. Vi ville ta del av lärares erfarenheter av särskilda undervisningsgruppers förändringsprocess över ett trettioårigt perspektiv, och lyfta fram förändringsprocessens positiva och negativa konsekvenser för eleverna i deras sociala utveckling och i lärandet så som lärarna uppfattar det. Studien har en kvalitativ ansats med narrativa intervjuer som metod. Den narrativa metoden syftar till att tolka och förstå lärarnas berättelser.
