This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms. This thesis bases on previous work on supply chain mapping and cost theories.

This quality study was carried out with seven semi-structured interviews and five of them were with elite women´s football coaches. What has been studied is how elite women?s football coaches are working with injury prevention training to their knees for the women?s football players. An anterior cruciate ligament injury in elite women?s football is both common and serious knee injury.

The subject for our bachelor thesis is how sugar is portrayed in Aftonbladet. By analyzing newspapers from 1995 and 2013 we wanted to research if the portrayal of sugar has changed during the years. We have noticed that there is a trend of being healthy and fit today. ?Strong is the new skinny? is a quote we can see in social media and on blogs today.

Every year an avorage of 40 000 Swedes fall ill with different forms of cancer. Chemotheraphy has an effect on the tumour cells as well as the healthy cells in the body, this causes many side effects which can be very problematic for the patient. The study was carried out in order to indicate the care measures that are taken to deal with the side effects i. e stomatit, loss of hair and sickness/vomiting, that are connected with chemotheraphy so that the outpatients will experience a quality of life. The method used was a qualitative interview with six nurses from the South if Sweden, all of whom are working with chemotheraphy patients.

Laminitis is a common but devastating condition, and affected horses are often euthanized or influenced a very long time. Many horses never return to their original capacity. Laminitis is often associated with severe pain and a long time of convalescence. Symthoms includes lameness, hoof hyperthermia, strenghthened digital pulse and pain. The horse often tries to move the body weight away from the forelegs which are often more severly affected than the hindlimbs.

Due to progresses constantly being made in veterinary medicine combined with increasing knowledge in pet owners, the dogs of today gets older than before. The population of geriatric dogs is there for constantly growing, which makes them an important group of patients on small animal clinics and hospitals. As dogs age, so do their interior organs. Geriatric dogs are prone to several diseases and in this text the author has decided to focus on three of the most common: Cognitive Dysfunction Syndrome (CDS), cancer and osteoarthritis (AO). All of these illnesses are incurable in dogs, but it is important to remember that they are still treatable.

The degree project was made forZetterbergs Industri AB. The company is market leading in Europe in the heavyvehicle industry, designing and building body systems for trucks.In their line of products is the hook lift called Livab, a flexible and uniqueproduct. The hook lift is often demanded by customers because its special ability tobe able to operate in situations with low roof clearance. The main operation principleof the hook lift can be described as a truck stand, laid down.There are two main versions of the hook lift Livab, AL 26 and AL 32. These are ofdifferent load capacity, 17 and 25 metric tons of gross weight respectively.

Syftet var att undersöka fyra hälsovägledares uppfattningar och strategier för att motivera individer till viktminskning. Avsikten var även att utreda vad de bygger sina uppfattningar och strategier på, samt att jämföra deras strategier med befintliga teorier om beteendeförändring såsom Motiverande samtal, Stages of change, Social learning theory och Health belief model. Teorierna valdes då de belyser hur en beteendeförändring kan gå till samt att de varit fram­gångsrika i tidigare forskning. Studien är kvalitativ och genomfördes med ostrukturerade intervjuer där respondenterna valdes genom ett bekvämlighetsurval. De fyra hälsovägledarna arbetade med att motivera individer till viktnedgång, alla hade utbildning inom hälso­främjande arbete som varierade mellan en vecka till flera år.

The objective of this paper is to estimate monetary and non-monetary costs for the huntercaused by deer-vehicle collisions in Sweden. These costs include losses in hunting value as wellas time and money efforts related to the handling of wildlife casualties. The calculations arebased on available statistics from 2004 on deer-vehicle collisions involving moose, deer, roedeerand wild boar and on telephone interviews with hunters involved in the tracking of injuredanimals. Altogether, the annual loss in hunting value for moose was assessed to approximately30 million SEK based on the 2004 accident statistics. For roe-deer and fallow deer, thecorresponding figure was approximately 56 million SEK and 1.2 million SEK, while wild boaraccounted for 1.3 million SEK, respectively.

The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein. The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.

Abstract The present study examined if early deaf people and people with severe hearing loss perceive visual information differently than hearing people. An experiment was conducted with eight deaf participants and eight participants with normal hearing. The participants were between the ages of 18-74 years. The participants were asked to look at fifteen different images portraying manipulated illusions, and then assess if the images were of the same size. Subsequently another image depicting a different illusion with a face hidden in it was presented to the participants.

This thesis has two purposes: (1) to analyze the emptiness in Blodbok by Christine Falkenland, and (2) to analyze my own reading of the same book. I have chosen to focus on how emptiness is expressed through the body, the language and the place in Blodbok, because of the deep impact these seem to have on the emptiness. The thesis discusses what kind of emptiness that is described, what it does to me as a reader, and how it is connected to other works by Falkenland. Cultural politics of emotions by Sara Ahmed, Uses of literature by Rita Felski and Pouvoirs de l?horreur by Julia Kristeva together form the theoretical framework.Blodbok is a poetry collection, about the loss of a mother.
