Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

På grund av nya EU-restriktioner måste biltillverkare sänka sina koldioxidutsläpp för att kunna konkurrera på marknaden. Denna rapport behandlar examensarbetet med att utveckla en vindavledare för Autokaross i Floby AB?s flakkåpa monterad på en Volkswagen Transporter. Syftet är att, på grund av framtida EU restriktioner på max 175 CO2/km för lätta transportfordon, sänka bränslekostnaderna och koldioxidutsläppet genom att minska luftmotståndet. En litteraturstudie kring hur aerodynamik fungerar gjordes och dagens marknad undersöktes för att se vilka lösningar som finns idag. Genom att ta del av en kundundersökning som Autokaross i Floby AB gjort kunde kundkrav identifieras vilka utgjorde grunden för kravspecifikationen.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

Traumatic arthritis is a common cause of lameness in horses. One of different treatment alternatives of arthritis, is intra-articular injection with hyaluronan. As knowledge about pathophysiology of arthritis and function of hyaluronan is increasing, understanding grows about the mechanism of hyaluronan action in joints. Hyaluronan has, in addition to effects on viscosity, anti-inflammatory and analgesic effects. Extensive research and scientific studies have been made on exogenous hyaluronan.

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

Pupil achievement and behaviour in schools was earlier seen as given by socioeconomic and biological factors. But since the late 1970s the school effectiveness research has come to give school factors a much greater role for pupils? attainments. Research has shown that schools´ pedagogical and social climate, which is to be seen as a complex product of deeply felt values and norms held by school principals and teachers and developed through practical actions, can explain variations in effectiveness between schools. Effectiveness is here to be seen as a higher mean cognitive and non cognitive student outcome than is expected with regard to initial attainment or family background.

FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances. A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used. As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.

The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

Water is an essential factor for both people and animals, and access to water is therefore of great importance. The water access also largely determines the availability of food for people and feed for animals. The aim of this study was to survey the affect of water access on milk production from dairy animals. The study included nineteen farm visits that were made in the Nyando district in Kenya between February and Mars 2011. Farm visits included interviews with questions about for example number of dairy animals, milk production, water access, feed and water routines.

The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.

The purpose of this study was to investigate how the content of glucose, fructose, sucrose and fructan (WSC) varied in silage, haylage and hay harvested from the same field and at the same time of harvest. The study also investigated if differences in the WSC-fraction in the forages caused differences in composition of WSC in the colon of horses fed the forages. Hay, haylage and silage were harvested in the first week of June 2005 and stored for about nine months before feeding. Horses that were fistulated in right ventral colon and caecum were used, but only the colon fistula was used for sampling. The fresh crop and the conserved hay, haylage and silage were analyzed for chemical composition and WSC-fraction.

Bakgrund: I intensivvårdssjuksköterskans arbetsuppgifter ingår att räkna och registrera vätskebalans. Normal perspiratio är mellan 800-1100ml/dygn. Vätskeförlust via perspiratio är svårberäknad och hos den kritiskt sjuka patienten är de individuella skillnaderna ännu större och perspiratio kan bli större än normalt.Syfte: Att undersöka om perspiratio räknas in i vätskebalansen samt vilka faktorer som påverkar beräkningen.Metod: En empirisk, deskriptiv och analytisk studie med kvantitativ ansats. Datainsamlingen skedde genom frågeformulär utdelade till vårdenhetschefer på intensivvårdsavdelningar i Sverige.Resultat: Studien visar att på intensivvårdsavdelningarna var det vanligast att vätskeförlust via perspiratio räknas in i vätskebalansen. På dessa intensivvårdsavdelningar fanns skillnader i vilka faktorer som påverkade beräkningen.
