Varför blev det inte som planerat? En studie över platschefers prognosarbete i anläggningsprojekt
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Integrering av pelletsfabrik med Rya kraftvärmeverk i Göteborg : en teknisk och ekonomisk utredning
Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.
Economizer i bostadsvärmepumpar
I takt med stigande energipriser finner fler och fler det lönsamt att installera värmepump för att reducera sitt energibehov. Värmepumpar har dock svårigheter att tillgodose värmebehovet när utomhustemperaturen sjunker under -10°C. Detta problem kan minskas med så kallade economizerkopplingar, denna rapport jämför de båda economizersystemen flash tank cycle (FTC) och internal heat exchanger cycle (IHXC). Eftersom det har visat sig att vinsterna med economizerkopplingar är som störst då temperaturlyftet är stort är det mest intressant att jämföra dem i luft/vatten värmepumpar. Detta på grund av att övriga applikationer som berg-, jord- eller luft/luft-värmepumpar inte utsätts för samma stora temperaturvariation då utetemperaturen faller.

Kommunala avskrivningar
In 1985 the Swedish Association of Local Authorities and Regions published a paper on recommended depreciation time on capital assets for the public sector. This paper should only be seen as guidance, but many municipals use it without any further investigations. Swedish municipals are not like private companies; one very distinguished difference is that they are not allowed to make any profit. The municipals in Sweden are regulated by the constitution law which means that they can not go bankrupt. The public and the private sector have different legislations that result in different ways on how they for example treat depreciations.
Hälsomässiga risker på vattenledningsnätet - En studie över samband mellan trycknedsatt ledningsnät och förhöjd risk för sjukdom i tre svenska kommuner

Projektledares synpunkter på projektprocessen
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

It looks for links between business travel and work satisfaction among them. A short presentation of the patterns of business travel and relevant motivational and stress theories is given. Data for the paper is collected using a survey (78 participants) and interviews.
Beredning av köldbärare för komfortändamål i kontorsverksamhet : En studie i produktionsslag
The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.
Corporate Social Responsibility : - Ses arbetet som en strategi och är det verkligen ett genuint samhällsansvar?
The purpose of this study was to examine what previous research says about children?s experiences living in a low-income family. Its aim was to found out what children themselves say about their life living in a low-income family and what consequences, practical and emotional, low-income environment has on children. More specifically our aim was to find out how children themselves experienced their situation compared with their peer?s economical situation.
Strokediagnostisering på akutrummet : Är standardiserade scheman användbara i strokediagnostiseringen samt anamnesupptagandet?
Amyotrophic lateral sclerosis is a progressive neurological disease which causes a slow degeneration of the body. Living with this disease means being exposed to severe strain and every day could bring new losses. Amyotrophic lateral sclerosis does not cause any harm to the intellect, the mind remains unaffected. The aim of this study was to achieve an understanding, and to shed light on the nature of positive life experiences of people living with amyotrophic lateral sclerosis. This literature study is based on detailed examination of three person's narrations taken from their autobiography and biographies.
Fjärrvärmens konkurrenskraft : En analys av olika uppvärmningsteknikers kostnadseffektivitet och kunders beslutsfattande
Historiskt sett har den Svenska värmemarknaden dominerats av fjärrvärmen som i princip varit det enda kostnadseffektiva alternativet där det funnits tillgängligt. På senare tid har dock spelreglerna börjat på att förändras, bland annat på grund av värmepumparnas intåg, en förändrad energipolitik och ökade kundkrav ? vilket har lett till en mer konkurrensutsatt marknad. Denna studie syftar till att både kvantitativt och kvalitativt analysera fjärrvärmens konkurrenskraft jämfört med alternativa uppvärmningstekniker, med fokus på segmenten flerbostadshus, övriga- samt offentliga lokaler.Efter en inledande marknadsundersökning bedömdes värmepumpar i kombination med el eller fjärrvärme, samt pellets i kombination med RME, kunna vara konkurrenskraftiga med fjärrvärme. Därefter beräknades livscykelkostnaden för dessa värmesystem för en generell fastighet som en funktion av dess energibehov och utnyttjningstid, samt för ett antal typanvändare.
Döden och livet därefter enligt en berättelse om liemannen : En kvalitativ undersökning av uppfattningar om döden och livet efter detta i Grim Fandango Remastered.
The purpose of this paper consists of examining the different ways of thinking about death and life beyond death conveyed in the game Grim Fandango Remastered. This was done by using a theoretical framework consisting of a self invented definition of death called "Bodily death". This definition consists of common notions about death such as cessation of life functions like movement, metabolism, respiration and overall cessation of brain functions. It also included cessation of vital processes, which includes the ability to make energy transfer, making reparations, for example by cell replication, as well as the waste system of the body. Besides this, the study examines the prevalence of dualism, a conception that views the soul essential to the individual's mental state. Two kinds of dualism were investigated, simple dualism with the assumption that the individual is made up of the soul, and compound dualism, where soul and body are dependent on each other for the survival of the individual.
Utfodring av rapsfoderråvara i fodersystem till mjölkkor
The feed is a major cost in the dairy production and there is a constant interest in findingalternative cost-effective feedstuffs. Competitive dairy producers have to seek ways todecrease their production costs and the pursuit of cost-effective feed rations contributesto lower costs of production. An interesting group of protein concentrates are rapeseedproducts like ExPro (heat treated rapeseed) which have during the autumn 2008 andspring 2009 been very favourable compared to other protein feeds.This study focuses on the feedstuff products ExPro and Raps-Drank 60/40 (rapeseeddistillersgrain). The potential use of ExPro in dairy cow feed rations are also explored.ExPro is a well known feedstuff but Raps-Drank 60/40 is a relatively new product andnot known for many farmers.A field study on the use of rapeseed products was made on a limited number of dairyfarms. The main purpose was to study the management of the feedstuffs on the farms.The Farms were selected in cooperation with two local extension services.
Yoga; spiritual balance of contemporary consumers
This research study constitutes a critical stand, which departure from the increase in welfare, and decrease in quality of life, and is further directed to the sphere of consumption. Contemporary consumers appear to seek for components to construct their self with through consumption, consumerism has become a sphere of life, and has consequently also become a victimizing force steering the identity and self construction of consumers. The alarm bells however are echoing in Western society, and consumers are experiencing dilemmas such as fragmentation, powerlessness, uncertainty and meaninglessness.In this respect we have presented spiritualism as an applicable path of escape or alternative to the scheme of the material oriented consumption sphere. We intend to broaden the scope of the interplay between spiritualism and consumerism in the act of yoga, and we have therefore been researching: what yoga is doing to consumers, and what consumers are doing to yoga. The study is based on an existential epistemology paradigm, which emphasis on the meaning of the yoga experience attained from the subjects of research; the yoga practitioners, and therefore we have carried out three focus group discussions.
