Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.

The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.

AbstractTitel: The optimal salary system in the real estate industry Authors: Emma Bjo?rkman och Tere?se Emanuelsson Widstro?m Tutor: Tommy BergquistProblems background: The challenges companies face is to recruit, retain and motivate empolyees to work in a way that promotes the company. Skilled staff are difficult to recruit, more difficult to maintain and expensive for companies to lose but undeniably the most important key to success. How should the optimal salary system be composed to attract operators in a competitive market such as real estate industry, with a predominance of commission based salary?Purpose: To examine how the salary system is linked to motivation and goals in the real estate industry.

TitelSkolsköterskans upplevelse av hinder för optimal hälsa hos skolbarn med födoämnesallergi -en intervjustudie. Författare Anna Lundberg ochUlrika Freund-ArvidssonSektion Institutionen för OmvårdnadUmeå Universitet 901 87 UmeåSammanfattningBarn med födoämnesallergier är ett ökande problem i dagens samhälle. För att kunna säkerställa att barn med födoämnesallergi har en säker skolmiljö krävs att skolsköterskan och personalen kring barnet har kännedom om barnets specifika behov. Syftet med studien var att belysa skolsköterskans upplevelse av hinder för optimal hälsa hos skolbarn med födoämnesallergi. Sju skolsköterskor intervjuades.

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

We have two aims with this thesis. The first aim is to describe CFD as a financial instrument in detail by highlighting its potentials and disadvantages. The second aim is to try to find the optimal real margin for each of the underlying stocks.We have adopted an inductive approach, combined with a quantitative method. We have worked with data and tried to come up to conclusions from the results we got.The conclusion of our thesis is that it is optimal to enter a CFD-contract with own capital covering at least 20 % of the value of the contract..

The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. ?Updating? in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning. The study also includes how the aerial photo material and experience of the interpreter can influence the quality of the interpreted variables. The aerial photo interpretations were made by both experienced and inexperienced interpreters.

Detta arbete undersöker 4 olika algoritmer som används för bred kollisionsdetektering. De olika metoderna för bred kollisionsdetektering kan delas in i 4 olika kategorier. Algoritmerna som är valda att representera varje kategori är Bruteforce, Sweep and prune, Hierarchical grid och Bounding volume hierarchy. Fokus i arbetet ligger i att mäta deras lämplighet för spelmotorer där det är viktigt att algoritmerna kan köras i realtid.Algoritmerna körs i simulationer av olika miljöer. Där antalet objekt, hur många som är rörliga och objektens distribution varieras mellan miljöerna.

På moderna missiler ställs inte bara krav på nedslagsposition utan i allt högre grad även på nedslagsvinkel. För hårt bepansrade mål är vinkeln kritisk då det finns risk att missilen studsar om den kommer in allt för flackt. Samtidigt ökar träffprestandan då en optimal nedslagsvinkel och nedslagsposition används. Med anledning av detta föreslås en styrlag för att reglera missilen efter på förhand genererade referensbanor i vilka nedslagsposition och nedslagsvinkel kan specifieras. Styrlagen är indelad i två huvuddelar och inleds med en optimal styrlag för att reglera ut navigationsfel från tidigare faser och ta missilen till referensbanan.

To make it easier for forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results. This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.

Koloni is a concert promoter that put up shows in lots of different locationswith a wide variety of music styles and artistic expressions. In this work I havecollected material from Koloni?s nine years of existence to form a volume. Thevolume tells the story of Koloni?s work, but also shed some light and understandingon the alternative cultural scene of today.

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.
