Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy cows. There are few studies about magnesium feeding to dairy cows in Sweden and the purpose of this study was to investigate how much magnesium and from which feed-sources dairy cows in Sweden get their magnesium. Data was collected from seven farms in the northern part of Uppland and from seven farms in Skaraborg in Sweden.

The shape and arrangement of the outdoor environment at a preschool has a critical impact on the possibilities to practice different pedagogic activities (Grahn et al.1997). At the preschool at Edwin Ahlqvists road, the employees are inspired by Reggio Emilia in their way of thinking, and they consider their outdoor environment is not suitable for the pedagogic activities they use. Reggio Emilia is a city in the north of Italy (Wallin 2001). The preschools there are famous for their pedagogy, their creativity and their democratic way of working (Dahlbech & Johansson 1986). The Reggio Emilia pedagogy is constantly renewed and developed, but with the children?s needs in focus and simultaneously with the quick changes of the modern society.

NCC has given us a commission to investigate a planned housing area in Haga, Karlstad, situated close to the traffic route Hagaleden and the railway. The housing area consists of one hundred apartments in five different houses. The houses are linked to each other by balconies with glass panels. A long carport is situated between Hagaleden and the housing area to absorb part of the noise from the road. The design of the housing area is creating a silent backyard.

Extensive cattle management was reintroduced in Sweden during the 1950´s and 60´s. Usually this term refers to suckler cows for meat production that is kept outdoors all year around. Suckler cow farms tend to become fewer but bigger over time. Still however most of the farms with beef cows are small. Extensive animal husbandry can lead to animals becoming shy which leads to difficulties when they are handled due to veterinary treatments, marking, transport etc.

The spruce bark beetle (Ips typographhus) is one of the 25 000 species of insects in Sweden, an insect of great economic importance because it can alone terminate forest of high value. During the past decade, insights of climate change received with increasing attention. If the future brings a milder climate in the north and therefore a longer growing season, one would think that it would only affect the forestry to the better? Yet in recent time, outbreaks after storm felling seems to occur more frequently. The Spruce bark beetle ruins millions of cubic meter of Norway spruce (Picea abies) in Sweden alone, with more frequent storm felling and a larger amount of wind thrown threes in the forests there will also be room for an advancing reproduction.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Många av Sveriges badhus byggda i slutet av 1900-talet börjar idag visa tecken på kraftiga fuktskador på grund av extrema inomhusklimat. Denna rapport förklarar den allmänna problematiken kring högt fuktbelastade byggnader och berör det fuktskadade badhuset Aquarena i Katrineholm.  Extrem noggrannhet krävs vid montering av ångspärr i en konstruktion, speciellt vid högt invändigt fukttillskott. Optimal placering av fuktspärren i konstruktionens varmare del innebär att fukt aldrig tillåts kondensera och därmed minimeras risken för fuktskador och negativa konsekvenser. Verkligheten visar också att om kunskaper om fukt och fuktskador prioriteras redan i ett tidigt stadium under projektering kan många hundratusentals kronor sparas. Beräkningar av fukttransport har gjorts för tidigare ytterväggskonstruktion i Aquarena (den som drabbats av skador) och nybyggd ytterväggskonstruktion (nyframtagen till återuppbyggnaden) i datorprogrammet WUFI Pro 4.2 och analyserats i WUFI Bio 3.0.

Oavsiktlig lindrig hypotermi förekommer hos upp till 60 % av de patienter som genomgår en operation. Hjärnans förmåga att reglera kroppstemperaturen under ett operativt ingrepp påverkas av läkemedel som ges under anestesi. De åtgärder som vidtas innan och under operationen för att minska temperatursänkning är ofta otillräckliga och behöver förbättras. Idag finns få rutiner för hur oavsiktlig lindrig hypotermi skall undvikas för att minska det lidande som kan uppstå då patienten oavsiktligt utsätts för avkylning perioperativt. Syftet med studien var att påvisa de risker och effekter som uppstår i samband med oavsiktlig lindrig hypotermi perioperativt, samt att belysa framkomna skyddande faktorer.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

In Sweden there are 560 000 disabled people over the age of 16, half of those are in use of some kind of mobility device.Living with a disability means that due to injury or illness you are having trouble functioning without devices or assistance in your daily life and has a big impact on the independence of the disabled user.The everyday life for disabled parents with young children are different depending on the type of disability and mobility device.Today there is no alternative to the stroller for the disabled user who use mobility advises. This causes problems when the disabled person on there own have/want to move the child.The following statement have been the cornerstone for this project: How to make it possible for a wheelchair user to move a child, in the 0-2 year, for longer distances with a focus on independence and safety for both adult children?Due the process, of industrial design, this question and problem have been solved during 10 weeks. The process have contained parts as meeting with users, analyzing, concept development, evaluations, mock-up making, testing, shape & color development etc. This in the end have resulted in a full scale model of the appearance of a proposed product.The result is a stroller witch can be connected to the users specific wheelchair due two one time adjustments.

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.
