Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten
Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.
Primär ciliär dyskinesi som orsak till kronisk lungsjukdom hos hund : en litteraturstudie och fallpresentation
Primary ciliary dyskinesia (PCD) is an important but unusual cause of chronic respiratory disease of young dogs. The purpuse of this paper is to study and present internationally publicated papers on PCD in dogs and present three dogs, in which PCD was suspected.
PCD has been reported in many dog breeds as well as in people. In dogs an humans, PCD is caused by inborn genetical defects which causes structural and functional abnormalities of cilia in the respiratory organs and other cilia in the body. Situs inversus occurs in about half the cases in people and probably in dogs as well. Respiratory signs usually predominate.
Redovisningsbeteenden En kvantitativ studie av meteriella anläggningstillgångar
Bakgrund och problem: God jämförbarhet mellan företag är en förutsättning för en effektiv kapitalmarknad och redovisningen är ett viktigt verktyg för att jämföra företag. En harmoniserad redovisning är därmed en förutsättning för att uppnå god jämförbarhet mellan företag i olika länder. Implementeringen av IASB:s redovisningsstandarder IFRS innebär att EU:s börsnoterade företag nu redovisar enligt samma standarder. Trots att företagen redovisar enligt samma standarder implementeras de olika, vilket tillsammans med det bedömningsutrymme som finns i standarderna innebär att jämförbarheten kan antas vara begränsad. Materiella anläggningstillgångar, som redovisas enligt IAS 16, är ett område där företagens egna bedömningar har ett stort utrymme, då exempelvis nyttjandeperiod bestäms subjektivt, och redovisningen av likadana ekonomiska händelser kan därmed skilja sig åt mellan företag.
Karaktärisering av äpplesorter : för framställning av juice och cider
The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.
Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering
The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.
How to build a rein tension meter
A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.
Resecentrums effekter på markanvändningen: praktikfall
Skellefteå
Syftet är att utreda effekterna av olika markanvändningsstrategier samt att skapa en bra grund för fortsatt planering vid skapandet av ett nytt centralt resecentrum i Skellefteå. Detta arbete förutsätter att Norrbotniabanan byggs samt att dragningen genom centrala Skellefteå följer korridoren för dagens järnväg. Arbetet bygger även på att järnvägen dras i markplan men stora delar av arbetet är användbart även vid en nedgrävd järnväg. Norrbotniabanan är ett, sett ur Skellefteås perspektiv, ett gigantiskt projekt. Metoden som används i arbetet är hämtad från SAMS (Samhällsplanering med miljömål i Sverige).
Strategiskt beslutsfattande : hur svenska lantbrukare agerar för att anpassa sig till sockerreformen
A severe profitability decline in sugar beet production in all of Europe is one of the consequences of the latest reform of the EU sugar regime. In south of Sweden, sugar beets is the crop that has been the most profitable by far for the last decade. The high profitability has contributed to the high rate of increase in the price of land and has restrained the structural change towards a more effective agriculture. Because of the reform, all sugar beet producers are facing diminishing income and must find ways to compensate this.
The aim of this master thesis is to study how Swedish farmers adapt to the sugar beet reform. A questionnaire was sent to 354 randomly selected sugar beet producers.
Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie
Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan
An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.
Gotland ponies on extensive pastures ? a welfare assessment
Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition.
The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed.
Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.
Trikåkonstruktion med 3D-effekt för väggpaneler i lastbilar, ersättning av polyuretanskum
En vanligt förekommande laminering är polyuretanskum, som används för att ge egenskaper som mjukhet, komfort och flexibilitet till textiler. Ett användningsområde som tillverkaren och leverantören Borgstena Group Sweden AB använder polyuretan till är lastbilars väggpaneler. De vill dock ersätta den polyuretanskumlaminerade dubbeljerseytrikån som används idag med endast en ren trikåkonstruktion för att slippa problem som dellaminering och minskade töjegenskaper. Dessutom så har den kemiska sammansättningen av polyuretan som används i lamineringen visat sig vara belastande för både miljö och människor. I denna rapport klargörs varför polyuretanskum behöver ersättas och vilka möjligheter som finns i dagsläget för att göra detta.
Isolerande och skyddande dubbelväv - Produktutveckling av ett kylande fodral
Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning.
Att spara eller inte spara? : En kvantitativ enkätstudie av informationslagringssystem för vetenskapliga artiklar
Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.
Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]
Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.
