Beteende hos lekvandrande lax i Klarälven ? utvärdering av en fiskfälla
During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

"Ni måste se det här klippet" : En studie av gymnasieungdomars Youtube-vanor
The purpose of this study is to show and explain how and why Swedish young people use Youtube.We conducted a written survey, asking approximately 120 students between the ages 16 and 18. The survey was carried out in the classrooms in order to receive answers from as many students as possible. We then interviewed six of them to gain further knowledge of why they use Youtube the way they do.The survey showed that Youtube is used by all of the students and very frequently by most of them. Comedy and music videos are by far the most popular genres that are viewed. In most cases watching video clips on Youtube is a social activity, often combined with both talking about clips and sending and receiving video links to and from friends.

Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager
It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006). Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Utvärdering av konsekvenserna för nätanslutning av vindkraftparker i Sverige vid införandet av nätkoden Requirements for Generators
Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. There is howeveran undeniable difference between the technology in conventional synchronousgeneration units, and the asynchronous generation units in wind farms.This thesis has reviewed the current grid code in Sweden and compared it to the newcode proposed by ENTSO-E, ?the Requirements for Generators?, in the aspect ofwind farms with an installed power of 30 MW or more. The comparison has beencomplemented by an analysis of how wind farms of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes.The Requirements for Generators contains many non-exhaustive and optionalrequirements, because of this it has been difficult to, at this stage, exactly point outthe technical impact on the grid connection of future wind farms in Sweden.

Proliferativ enteropati hos gris : patogenes och patologiska förändringar
Proliferative enteropathy is a group of disease conditions in pigs where the disease may vary from subclinical to critical with bloody loose feces. The etiological agent is the obligate intracellular bacteria Lawsonia intracellularis. L. intracellularis infects enterocytes from jejunum to colon. The bacteria is taken into cells and start to replicate and cause a massive proliferation of immature enterocytes.
Konstruktion av mutterdragare för stora moment
This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
Vågor mot klippan? ? en intervjustudie av godmanskapet inom funktionshinderomsorgen och dess praktik
Being a trustee within the disability care will, in most cases, put big responsibility on the trustee both as a representative for the klient but also as a representative for the standards of the society. The assignment as a trustee is to strengthen the client and ease his/her way of living in the society. The Swedish legislation that controls the process and the regulation of the trustees, is by the authors of this paper preceived as kind of vauge, leaving a lot of room for interpretation. So how do trustees comprehend their assignment and how do they actually interpret it? Using material from eight interviews with trustees within the disability care, this paper aims to examine these questions, and focuses only on the trustees and their experiences.

Hjärtfrekvensvariabilitet hos friska hundar
In healthy dogs, heart rate fluctuates during the day. Heart rate variability (HRV) reflects the autonomic nervous system´s regulation of the cardiovascular unit. Heart rate variability shows the balance between the sympathetic and parasympathetic nervous system, also called sympathovagal balance. Heart rate variability can be measured by time domain - and frequency domain analysis. In a time domain analysis you study the beat-to-beat-interval (RR-interval) in an electrocardiogram (ECG), while a frequency domain analysis can be used to determine the size of the variability.
