The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

En litteraturstudie om effekter av fysisk aktivitet på recept av Anneli Björk-Andersson och Jenny Bylund, Institutionen för hälsovetenskap Luleå tekniska universitet. Tanken med studien var att ta reda på effekterna av fysisk aktivitet, hur man arbetar med fysisk aktivitet på recept i Norrbotten samt hur det ser ut i övriga landet. En litteratursökning som innefattade 45 artiklar, rapporter och uppsatser samt fem olika läns landstings webbsidor genomfördes. Några av landstingen har kommit långt i sitt arbete med fysisk aktivitet på recept och eftersom det var lättast att hitta material om dessa valdes de ut. Resultatet var tydligt, man har mycket att vinna på att vara fysiskt aktiv.

In recent centuries the Swedish Tiled Stove has varied in its design with an aesthetic evolutionary history that has not only followed the architectural and artistic ideals but also the taste in stove design. The heat source has varied depending on the regional traditions and where it was located within the country, but the inside of the construction was of a similar five channel system. The purpose of this paper is to study and compare the design of tile matrices made by Emil Petterson with other Swedish stoves. The following questions will be addressed:What characterized the production of a small scale tile stove workroom during the years 1900-50? Which main styles can be described as Emil Pettersson?s ideal while producing his matrices? And finally, is it possible to study the tile stove matrices as objects of historical and cultural significance, and what difficult methodological issues might occur in the doing of it? To answer these questions I will present the results of the documentation of Pettersson?s tile matrices with detailed historical categorizations and schedules. The conclusion shows that Pettersson as a stove builder and -producer was characterized by eclectic ideals and a design shape based on more liberal interpretations of contemporary trends.

I Sverige drabbas ca 35000 människor av stroke varje år, av dem får 8000 afasi. Afasi ger talsvårigheter både i att förstå andra och att uttrycka sig. I vården möter sjuksköterskan ofta patienter med afasi och kommunikationen blir då inte lika självklar. Sjuksköterskans uppgift är att ha en kommunikation där de kan förstå varandra. Vårdrelationen är nödvändig för kommunikationen och för att göra patienten delaktig.

Arbetsterapeuter är uppmärksammade för att utföra observation i aktivitet vid bedömning av klientens förmågor. Arbetsterapeuter verksamma inom slutenvården med strokepatienter utreder klienters förmåga i utförande av aktiviteter i det dagliga livet [ADL]. Som stöd till utredning i det praktiska arbetet kan observation användas för att se klientens utförandekapacitet. Syftet med studien var att beskriva arbetsterapeuters erfarenheter av faktorer som kan påverka observation vid aktivitetsutförande. En kvalitativ ansats valdes som metod och datainsamling gjordes med halvstrukturerade intervjuer.

The objective of this report is to present a review of the studies which has been carried out up to days date concerning how temperature affects vegetables physiologically when it comes to their health inducing as well as quality reducing features. The essay therefore starts off with defining what is meant by the terms health promoting and quality reducing features. It then moves on to describe how different subspecies of Brassica oleracea, that is to say vegetables such as broccoli, cauliflower, Brussels sprouts and kale, is affected by temperature. B. oleracea was chosen because the species contains several commercially interesting subspecies and therefore provides a broad field even though only one species is assessed.

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

AbstractAn approaching overproduction of cereals and a future uncertain supply of non genetic modified vegetable protein feedstuffs have increased the interest in an expansion of the domestic production of protein feedstuffs in Norway. Besides rapeseed (Brassica campestris), peas (Pisum sativum) may be the most suitable crop for this purpose. Peas are characterized by having a relatively high content of crude protein, ranging between 20-26%, a high content of starch, 42-51%, and a low content of fat. In general, the energy value for peas is higher than for barley but lower than for rapeseed and soybean meal.Pea protein consists of albumins and globulins to 85-100%, which leads to the fact that a large part of the pea protein is soluble and degradable in the rumen. Starch in peas is on the other hand to a large extent resistant to rumen degradation compared to starch from other starch rich feedstuffs.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Än så länge är den vanligaste orsaken till amputationer av nedre extremiteter, njursvikt och blindhet. Sjukdomen orsakar årligen stort lidande, sjukhusvistelser och nedsatt funktionsförmåga hos de drabbade människorna. Syftet med denna litteraturstudie var att beskriva människors upplevelser av att leva med typ 2-diabetes.

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
