Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

AbstractThe purpose of my essay is to describe how some educators perceive the cooperation that takes place every day in the team to wich they belong. To do this, I have implemented six qualitative interviews with educators at two diffrent workteams. I based my questions on three scientific questions:- How does the cooperation in the team work?- How has the cooperation between the various kind of educators developedsince the pre-school class and the leisure-time centres was integrated with the school?- Which conditions exist for a good cooperation?The result showed that there were both similarities and differences between the teams, but common to both teams was that the educators felt that there have been some major positive changes to the cooperation in the teams in the last few years and that they were fairly satisfied with how the cooperation of their teams function now. Mostly they cooperates during school hours with various school projects, but questions concerning the pupils wellbeing is also an important area of cooperation.Since the integration was implemented, the cooperation has become more equal and the various educators have found their respective roles.

Ett utvecklingsarbete med gymnasielever om faktorer som ligger utanför skoltid och som de anser inverkar på deras skolprestation. The purpose of this paper was to develop a material that highlights what causes there were outside school that pupils thought affected their performance in school. This was strictly done according to the statements that the pupils made. To fetch these statements the paper used essays, interviews and inquiries, all of whom were presented for the pupils. Initially we asked the pupils to write a short essay where we wanted them to describe circumstances in the classroom, in school and spare time that affects their performance in school.

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Watching television (TV) has been given a new meaning, you don?t have to book a specific time, a specific date if you don?t want to miss the program you were planning to see. In Sweden now days we can watch TV in lot of different ways, whenever we choose to do so. In this thesis I attempt to explain and document the process of shaping a tvformat, the development and adaptation to a time when the TV medium is in a change. Plus a look at how the television audiences relate to their use of it.

AbstractHerbivores can be classified into either hiders or followers depending on their postpartum behaviour. The two behaviour types affect the spatial relationship between the mother and her infant. Goats are seen as hiders, although the environment plays a central role when it comes to the behaviour. Therefore, in the first part of this study the aim was to investigate how the goat kids? spatial relationship changed in the transition from indoor housing to pasture.

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

This master?s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped caches.

In this essay, I compare ten different depictions of the Irish Easter Rising of 1916. These depictions are all from books published between 1924 and 2000, which deal with a wider context of the history of Ireland or Northern Ireland. I relate the depictions to the point in time when they were written, the geographic focus of the book, and the views that the author expresses about the present and the future, and about the significance of history. The main result of my essay is that the depictions differ in a way that seems connected to whether or not there was an ongoing violent conflict in Ireland at the time the books were written. Texts written when the political violence was present, or close, in time and location, are likely to be written either in a neutral tone with concern about objectivity, or incorporating the Easter Rising events in context of an ongoing socialist struggle.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

"Ekskolan" is a monumental school placed in the middle of the new town area "Mariehäll" in Stockholm, Sweden. 600 pupils between preeschool until year 5 will use the school and its big schoolyard between the townsquare and the public park.The school will be built in massiv wood, both for human reasons with a environment of good, healthy and suitable material for the people and the school activity.The school is seperated in 3 volymes that organises different years; house B and C, and the common facilities: house A. The scool has a cultural profile with rooms for creative activites, documentation and exhibition.To mark the border to the public places that surround the scool and to meet the inclined topography, the schoolhouses will stand on a terrace. The terrace creates rooms between the houses that can be used to utdoor teaching. Likewise, the terrace creates a opened sightline between the public rooms and all the way down to the river..

Computerized methods for searching pictures are becoming more common. With these it ispossible to make powerful search requests using a combination of terms and search oncomprehensive descriptions of the pictures. The descriptions can encompass various aspectsof the content and allow different interpretations and levels of detail.This essay is about how you can examine and describe the content of a picture from manypoints of view. We have tried to identify differences in searching behaviour, and studiedsome methods for indexing of pictures. Our concepts are taken from the philosophy of artand from theories about the meaning of languages.In the future perhaps libraries can make pictures and illustrations in books available to thepublic, in a sophisticated system, for the purpose of providing visual documentation forstudy, research or other kinds of exploitation..

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses. The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.

The purpose of this research has been to find out whether and how teachers stimulate and motivate well achievers in the elementary school to reach a higher level. To gather information I visited two different schools within the same county in Stockholm and on each school I met and interviewed with two teachers. The answers received from these interviews are presented in this study as my results. I found that the teachers feel that students that do well in the classroom many times work as role models for the other students. Often these students require extra material as they usually finish their workload ahead of others.
