Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
Erfarenhetsåterföring i Sveriges två ledande byggbolag : Riktlinjer, utfall och konsekvenser
The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.
Införande av mjuka golv för mjölkkor : en fallstudie
Soft rubber flooring have gained in popularity over the last years. Rubber flooring al-lows cow to move more freely without slipping and improves claw and leg health. The purpose of this study was to investigate the influence of a stepwise introduktion of soft flooring on cow`s placement in cow houses with robotic milking.
A case study was carried out in a herd in northern Sweden with 41 cows. Observations were made every 15 minutes between 09.00 and 16.00 concering cow placement in cu-bicles, in cubicle alley, in feeding alley and in feeding alley with the head through feed-ing gate. One observation period was carried out per flooring alternativ: 1) all concrete slatted floor, 2) rubber slatted floor in feeding alley and concrete slatted floor in cubicle alley and 3) rubber slatted floors in feeding alley and solid rubber floors in cubicle alley.
The study showed that 6 %-units fewer cows lay in the cubicles when the feeding alley surface was slatted rubber.
Produktionseffektivisering : - Få processens samtliga aktörer att sträva mot samma mål genom ökat samarbete och delaktighet i produktionens olika skeenden.
The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.
Diskrimineringsersättningen och dess avskräckande verkan : Förarbeten och praxis ur ett arbetsrättsligt perspektiv
The aim of this study was to give an insight of the construction of girls in their relationships with friends and lovers in the Swedish magazine Julia. The magazine turns to girls of age nine to fourteen. The research questions were 1) What is the construction of the girls in their relationships with friends and lovers about in Julia? 2) How are girls constructed in their relationships with friends and lovers? Three issues of the magazine from the winter of 2014 were selected as material for the study. Critical discourse analysis (Fairclough, 1992, 2010) was the point of departure in the analysis.
Avfall på byggarbetsplatsen : statistik som hjälper platschefen
The purpose of this report is to find a model of statistics for construction and demolition waste, which makes it useful for the local manager at the building site. The intention with the model is that it will be used as a support of the local manager, to direct his project towards reduced strain of the environment. The model will also be used to make it easier to control that the claims from authority and aims for the environment are achieved. To familiarise with the subject waste handling within the building and construction sectorI have done a literature search. I have also been studying rules and regulations regarding the waste handling.
Från knackningar till blodspår - Analys av Marie Hermansons Mannen under trappan
This essay examines the differences and similarities, weaknesses and strengths of the two Cognitive Semantic theories Conceptual Metaphor Theory and Principled Polysemy Approach to Meaning Analysis. To illustrate the two theories, the Swedish verb-particle construction "gå upp" is examined and analyzed accordingly. The results showed differences in the number of polysemous meaning found. The methodological evaluation showed that the differences in the underlying ideas concerning meaning-construction behind these two theories make them incompatible..

Ett nytt växtsortiment - för inglasade miljöer :
A new project has developed at the Swedish University of Agricultural Sciences in Alnarp during the spring of 2006. The garden design students has, during the course Interior Garden Design designed and built an construction with a new range of plants for Swedish conservatories. The plants are mainly from the cool temperate areas, instead of the tropical which often are the most common in public spaces. This means, among other things, that the cost for warming is very low.
The working process and the construction carried on as workshops in the conservatory at Trädgårdslaboratoriet in Alnarp. During a few weeks the hole construction is completed.
?Barnets bästa i första rummet? : Om diskurser och språklig praktik i diskussionsprogrammet
Childhood as a social category is under strucural redefinition. In this thesis the child and childhood are understood as socially constructed phenomenons. Focus is laid upon the construction of the concept ?in the best interest of the child? wich in The UN Convention on the Rights of the Child is defined as beeing the foremost important view to take into account when decisions wich affect children are made. As the thesis shows, a concrete and universall view of the best interest of the child is lacking in practice and would in many cases be unfortunate.
Inhysningssystem för växande ungtjurar
The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.
Användning av högpresterande betong i husbyggnader : Materialförsök och modellering
Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.
Eurokoder : en jämförelse mot BKR
In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.
