Reaktionskrafter i dragarmarna på en traktors trepunktslyft : Teori och praktik
Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.
Idiopatisk cystit hos katt : en retrospektiv studie
Lower urinary tract diseases are a common problem in cats all over the world. The symptoms are for example dysuria, pollakuria, stranguria, periuria and hematuria. In approximately two thirds of these cats the underlying cause is not known and the disease is therefore called feline idiopathic cystitis (FIC). We need to know more about the disease to get a consistently effective treatment and prevention.
A retrospective study was performed in 50 cats with symptoms of FIC and where other causes of inflammation were ruled out. Data like breed, age, sex, body weight, feeding, therapy and therapeutic results were collected, also if it was an indoor or outdoor cat, duration of the symptoms, if there was any stress and if the cat was living with another cat.
Att fylla tidningarna med kris : En studie av kriskommunikation, nyhetsmedier och deras källor
The purpose of this study is to discover and explain the influences of media coverage of organizational crises on crisis communication, and vice versa. The study also shows how mediated crises develop, and how media framing and news sources affect this development.Carried out as a case study of three Swedish mediated crises, the methods used are quantitative and qualitative content analysis of media content from four Swedish newspapers and four organizations' press releases from the studied crises.Mediated crises develop through their specific pattern regardless of, but not independent from, the organizations' crisis communication. The crisis communication is used as an elite source in media reporting from the crises, but it can not control the mediated crises. However, it influences framing, and the possibilities to influence media reporting are better in the pre-crisis phase and the culmination..
Spårning av miljöstörande ämnen i Uppsala stads spillvattennät
To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.
Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter
When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.
"Det sås ett frö där som liksom sakta gror" : Att utveckla ett empatiskt och professionellt förhållningssätt under sjuksköterskeutbildning
In human service organizations it is important to enlighten the significance of human encounters. The aim of this study was to explore nursing students experiences of developing empathy and professional relationship in encounters with patients and next of kin during their education. Interviews with five nursing students were carried out. The method of analysing content analysis was used. One main theme and five subthemes were presented.
Biomass losses during short-term storage of bark and recovered wood
Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).
Elektrolytlösningar som vätsketerapi hos mjölkkor med löpmagsförskjutning :
Ten cows suffering from displacement of abomasum (DA) were treated with two different electrolytesolutions. The DA cows showed symptoms typical for the disease. Four out of 10 cows had a metabolic alkalosis and two a metabolic acidosis. The cows were mildly hypocalcemic, and 9 out of 10 were mildly to moderately hypokalemic. Six out of 10 cows showed muscle fasciculations.
Politikens medialisering : En kritisk diskursanalys av fyra ledande politikers twittrande
The empirical material of this study consisted of tweets by four leading politicians in Sweden: Carl Bildt of Nya Moderaterna, Annie Lo?o?f of Centerpartiet, A?sa Romson of Miljo?partiet and Jonas Sjo?stedt of Va?nsterpartiet. The aim of the study was to examine how they use Twitter as a political tool and what that says of the mediatization of politics. What content did they publish, how did the content differentiate between them and what political messages and other subjects occurred in their tweets? Does the political debate become fragmented because they?re only allowed to use 140 characters on Twitter? The theoretical framework and method applied for the research was based upon critical discourse analysis (CDA), with special interest in ideology and mediatized discourse.The result of the study showed that the content they published consisted mostly of criticism towards political opponents, rather than of independent political opinions.
Buntning av grot med lastbilsmonterad utrustning :
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.
Den nya tidens idrottsundervisning : En kvalitativ studie om fakta- och förståelsebaserad undervisning i träningslära
Aim: The purpose of this study is to, referring to Shulman?s pedagogical content knowledge theory (PCK), examine how selected Physical Education teachers, educated in GIH and with a maximum of two years' work in upper secondary school, pursue their education in training theory. Moreover, another purpose is to examine how their education at GIH has prepared them for teaching in this subsection. Questions to be answered:? What are teachers' attitudes to training methods as part of physical education and health in upper secondary school?? In what way, referring to PCK-theory, are teachers working with training theory??In what way do the teachers think that their education at GIH has contributed to their teaching in training theory, referring to the pedagogical content knowledge theory?Method: The study has a qualitative approach and study design consisting of five semi-structured interviews with teachers working with Physical Education in upper secondary school. The selection was made considering that all teachers have been educated at GIH and had a maximum of two years working experience.
Från rollspel till roman : En inblick i den intermediala dialogiken mellan Dungeons & Dragons och The Crystal Shard
The aim of this paper is to elucidate and analyze history teacher's didactic choices in the conflict between unequal educational materials and the requirements of equality in the curriculum of Swedish secondary school. The empirical data consists of interviews with five secondary school history teachers, observations of their lessons as well as analysis of their tests. The starting point was to investigate teachers' didactic work in the role as a bridge between the non-equal historiography presented in textbooks in history and the curriculum?s demands for equality. Three different approaches have been observed in the teachers' didactic work when considering gender perspective into their teaching: that women become extensions in a male-dominated historiography; that another part of the story is presented when a gender perspective is considered; and that the gender perspective is included in history teaching and becomes an integral part of all the content of the subject.Several of the teachers acknowledged that gender equality is less prioritized than the courses core content and related assessment criteria.
Barnsjuksköterskors erfarenheter i möten med små underviktiga barn och deras föräldrar
The aim of child health care is to promote health and development for all children, to early identify problems that concern children´s growth and development and to prevent ill-health among children. Today in our society the proportion of children who are underweight are few.The aim with this study was to describe paediatric nurses experience in meeting with underweight children and their parents. Interviews were implemented and analyzed according to qualitative content analysis. Focus was placed on looking at differences and interpretations in the text content. The analyse resulted in six main categories, such as a need of sensitivity and a holistic view from the nurse, difficulties in handling the meeting because lack of tools.

Sammanvägda avrinningskoefficienter i rationella metoden : en jämförelse mellan idag och 1970-talet
Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.
