VDC i produktionsfasen Implementering av virtuellt byggande för Veidekke Bygg Väst

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

Jämställdhetsindikatorer : en studie över jämställdhetsindikatorers potential att medföra kvalitativa jämställdhetseffekter

Det verkar råda en stark uppfattning om att indikatorer inverkar positivt på jämställdhetsarbeten. Samtidigt pekar genusvetenskaplig forskning på att kvantitativt jämställdhetsarbete inte är tillräckligt för att uppnå jämställdhet. Syftet med denna uppsats var därför att undersöka i vilken utsträckning jämställdhetsindikatorer kan medföra kvalitativa jämställdhetseffekter. Med fallstudie som metod och begreppet maktförskjutning som analytiskt begrepp har Uppsala universitets jämställdhetsindikatorer analyserats. Analysen visade på att universitetets jämställdhetsindikatorer med stor sannolikhet kommer medföra jämställdhetseffekter, men inga kvalitativa sådana.

Tillvänjning av labradorer att skritta och trava på löpband :

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

Effekten av olika andelar grovfoder och kraftfoder i foderstaten på mjölkproduktion, välfärd och hälsa hos mjölkkor

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

Hyperton vätskebehandling av kor med högersidig löpmagsdislokation :

The aim of this study was to investigate the effects of an infusion of hypertonic saline solution (HSS) in combination with an oral waterload on cows suffering from rightsided displacement of the abomasum (RDA). Six dairy cows were treated with 7,2% HSS in a dosis of 5 ml per kg bodyweight. They also received an oral waterload of approximately 15 liters. To monitor changes in fluid-, acid-base- and electrolyte-balance, bloodsamples were collected during the next 24 hours. During this period, the cows also underwent surgery to empty and correct the position of the abomasum.

Ultraljudsundersökning av buken på vuxna nötkreatur :

Ultrasound is still a relatively new method for the diagnosis of abdominal conditions in cattle. The objective of this study is to evaluate ultrasound as a diagnostic tool for the common diseases affecting high-producing dairy cattle, for example traumatic reticuloperitonitis, right- and left displacement of the abomasum, fatty liver, wound infections and abscesses. This paper is a combined litterature study and a report of the results from ultrasound examinations of bovine patients at the ruminant clinic at the Swedish University of Agricultural Sciences. The study includes two healthy cows from the ruminant clinic, and seven patients with abdominal related diseases. The examinations were made with a 2-6 MHz curvilinear transducer and both the right and left sides of the abdomen were scanned.

Framtagande av ny höjdmätningsmetod till försvarets antennhiss 861

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

Stakeholderperspektivet och utestängandet av det politiska: Om stakeholderperspektivets begränsade möjligheter att förändra miljöpolitiken

In contemporary global environmental governance stakeholding, as a means for defining legitimate participants in democratic decision-making, has become of great importance. In this essay I deploy the concept of ?the stakeholder perspective? to denote arguments that all stakeholders ? defined as carriers of particular interests ? should be able to participate in political decision-making affecting their interests. The purpose of the essay is to analyze the stakeholder perspective's potential to change environmental politics. Departing from the philosophy of Heidegger, I develop a theoretical approach that separate the concept of the political from that of politics.

Idrottslig prestation och ekonomisk ställning : En sambandsstudie i fotbollsklubbar

Purpose: Examine if there is a connection between the athletic performance and the financial status in football clubs.Theoretical perspectives: This thesis is based on the theory that the modern football club is like every other company trying to maximize profit. The clubs should therefore use the same business strategies.Empirical foundation: The study is based on 25 observations over five years and five Allsvenska football clubs. The data is a compilation of the key ratios from the annual reports and the league table, years 2004 through 2008 in the clubs. Year 2009?s league table place is also included since tests have been done with one year?s displacement between the financial status and the league table.Conclusion:There is no correlation between solidity and the place in the league table in Allsvenska football clubs.There is no correlation between net profit and the place in the league table in Allsvenska football clubs.There is no correlation between equity and the place in the league table in Allsvenska football clubs..

Varför värdegrund? : En studie av skolans moraliska fundament

School and education are topics that are frequent in Swedish media. The intention of this essay has therefore been to investigate the image of teachers and their profession in Swedish daily press. The overall aim has been to analyze how teachers are portrayed in the debate that followed the TV-show Klass 9A, and by that find how the debate defines the concept of a good teacher. The representation that was found was then compared to earlier studies. The series was shown on Swedish television between January and March 2011.26 articles were chosen and the ambition was to have various perspectives represented, such as different voices and also papers from different areas of the country.

Det oerhörda i verket : En undersökning av konstverket som ort hos Martin Heidegger

The present essay aims to understand the work of art as place on the basis of Martin Heidegger?s conception of work in Der Ursprung des Kunstwerkes from 1935. That is, a place that cannot be understood in accordance with the physical-technological space, but which cannot either be thought of as mere temporal spacing. This is accomplished by reading Der Ursprung des Kunstwerkes through the shorter essay Die Kunst und der Raum from 1969. Despite the time difference, Die Kunst und der Raum opens up Der Ursprung des Kunstwerkes in such a way that the work cannot be understood as if it were only a temporal event ? as the cause initiating a temporal process or succession of truth.

Är gnagare reservoar för encefalomyokarditvirus i svenska grisstallar?

Syftet med denna studie är att undersöka prevalensen av obstruktiva problem från de övre luftvägarna hos svenska travhästar vid maximal ansträngning. Undersökningen genomförs med hjälp av en ny typ av utrustning där man kan endoskopera hästar under maximalt arbete på en travbana.Tidigare har undersökning med endoskopi på rullmatta varit enda sättet att undersöka hästar under ansträngning, men tack vare ny teknik är det nu möjligt att göra det vid maximalt arbete, under för hästen normala tävlingsförhållanden. I studien ingår 110 varmblodiga travhästar som sökt för missljud från de övre luftvägarna, nedsatt prestation eller båda delarna. Hästarna undersöktes med endoskopi, både i vila och under maximalt arbete. Resultaten i vila och vid arbete har sedan jämförts.Diagnostiska bilder har erhållits från samtliga hästar och därmed kan prevalensen beräknas i den undersökta populationen.

Allt utom byn Sökandet efter en vikingatida by i sydöstra Blekinge, med områdena runt Järrestad på Österlen och Sorte Muld på Bornholm som jämförelsematerial.

The purpose of this essay is to see if villages or bigger settlement locations can be found in south-eastern Blekinge during the viking age. There have been many archaeological findings from this period in Blekinge, for example grave findings, ring-forts , old roads and ancient harbors. But no evidence of a village has been found yet. If south-eastern Blekinge is compared with the area surrounding Järrestad on Österlen in south-eastern Skåne and the area surrounding Sorte Muld on Bornholm, many likenesses can be seen. In this essay, the findings in Blekinge will be used as different components when the three areas are compared with each other.

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.
