Betydelsen av social rang på beteende och mjölknings­parametrer i ett automatiskt mjölkningssystem (AMS) :

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Växthusvävens fukttransmission ? Hur struktur och materialval påverkar växthusvävens fuktgenomsläpplighet

Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.

Vidareutveckling av beräkningsmodell för reduktionsgrader och avkylningseffekter i luftade dammar

Rapporten behandlar arbetet med att förfina, utveckla och dokumentera en beräkningsmodell för simulering av biologisk nedbrytning och temperaturförhållanden i luftade dammar. En luftad damm är en enkel typ av biologisk rening där mikroorganismernas biologiska nedbrytningen av oganiskt material påskyndas genom att syre tillförs ? vanligen med hjälp av ytluftare.  Arbetet är ett examensarbete inom ramen för högskoleingenjörsutbildning i kemiteknik vid KTH och har utförts på uppdrag av ÅF Industry AB som har använt beräkningsmodellen sedan 1970-talet. Modellen togs fram med hjälp av tidigare forskning, data från befintliga anläggningar och nedbrytningsförsök utförda i laboratorieskala.I arbetet har ingått att sammanställa och dokumentera erfarenheter och bakgrund till de beräkningsformler och konstanter som används i modellen. Vissa förenklingar har gjorts genom att lösa ut parametrar ur ingående beräkningssamband och genom att avläsningar ur diagram och successiv anpassning har ersatts med beräkning från en kurvekvation.

Vakuumisolering ? Ekonomiskt försvarbart för småhus?

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

Emissioner i slutna utrymmen Med speciell inriktning på emissioner av formaldehyd och organiska syror

This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.

Out of this need social media has emerged as a tool forcompanies to improve their communication with customers. The popularity of social media isincreasing at a rapid rate and sites such as Facebook now has around 500 million usersworldwide.

Ungdomars berättelser om Hovsjö : En kvalitativ studie om hur sex ungdomar i åldrarna 21-26 ser på sitt bostadsområde

Background and problems: All that is stated in social media might not always sometimes be right, which has consequences for the individual's view of the described phenomena. The individual interprets and takes in mass media messages, which can lead to that the wrong information makes believed to be is correct one. The news media?s photo illustrations might pictures result in bad images of the suburbs. Hovsjö, residential area in the city of Södertälje, occurs in the media depicted as is a bad place to live due to the high rate of crime there.Purpose and Issues: My main research question is: How do young people view their residential area Hovsjö in comparison with the image they believe consider is given in that the news media gives the area? Further questions of the study are: How do the young people of the district describe their residential area? How do the youth's react to the news media images of Hovsjö? Has the neighborhood helped to form their identity?Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews.

Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Immunmedierad hemolytisk anemi hos hund : en retrospektiv studie

Immune-mediated haemolytic anaemia (IMHA) is an immune-mediated destruction of erythrocytes and is one of the most common haematological diseases diagnosed in dogs. The haemolysis is a type II immunoreaction and is initiated by IgG or IgM antibodies or complements. This retrospective study includes 63 dogs suffering from primary IMHA. The study was based on information from records from the Swedish University of Agricultural Sciences, Department of Small Animal Clinical Sciences in Uppsala and from the Animal Hospital in Strömsholm. The aim of the study was to evaluate the progress of the disease, treatment and the prognostic factors in different breeds, gender and age. Following criteria were used for the dogs to be allowed in the study: the dogs were diagnosed with anaemia, the anaemia was regenerative and autoagglutination and/or spherocytes were seen in the blood. About 50 % of the dogs in the study were diagnosed with IMHA within 2-6 years of age. Wire-haired dachshund was remarkably one of the most common breeds in this study together with Cocker and Springer spaniel.

Svenska Lantchips : Och deras internationaliseringsprocess

Svenska Lantchips is a Swedish SME sized snack manufacturer. Being a small, medium sized, family-owned business with branches throughout the world, they make an interesting company for a case study. The case study I have conducted focuses on the internationalisation process of this family owned company ? how they, despite their size, find ways to keep up an unique business structure, designed for internationalisation.The aim of this essay is to compare Svenska Lantchips? internationalisation process with traditional internationalisation theories and see if these are compatible with this company. The theories used are The Uppsala Model, The Network Model, and The Born Global Theory, with The Born Global Theory representing the younger generation of models.After undertaking an in-depth interview with Michael Hansen, business developer at Svenska Lantchips, I collated a substantial amount of material, which I have used as the basis of this essay.

Fågelbär (Prunus avium L.) - överlevnad, höjdutveckling och skador i unga planteringar på småländska höglandet :

Plant survival, plant damage and height growth were studied in nine wild cherry (Prunus avium L.) plantations in southern Sweden established between 2000 and 2002. All stands were located to the county of Småland. The survey was conducted during May and June in 2007. During the survey the height, diameter and quality of the cherry trees were recorded. In one stand, red ? berried Elder (Sambucus racemosa L.) was a dominant species.

Koldioxidavgång vid ekologisk odling på organogen jord

The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.

Färsk ved till Hallstaviks pappersbruk :

During year 2000, Hallstavik used approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.
