Inverkan av ensilagets partikelstorlek på beteende och beteendestörningar hos mjölkraskvigor :
Modern milk production have come a long way when it comes to accommodating the
nutritional and physiological needs of the animals, but unfortunately the behavioural and
psychological needs of cows and heifers are often left unfulfilled. A long time for eating
is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours.
The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the
breeds SR and SF were housed in 8 slatted floor pens.
Nystartande av nötköttsproduktion med och utan bidrag :
Many dairy farms doesn?t keep their bull calves and cross cow calves, they sell them to
breeders instead of raising them their self. It should be possible for the dairy farmers to do it
them self?s. There is also a possibility to bread one calf from the cross heifers.
The purpose of the investigation was to see if there is any economic possibility to breed beef
cattle.
I have used the same sample farm trough the hole study, because it would be easier to fallow
the study.
Ägarnas motiv till börsnotering - värderelevant för investerarkåren?
This paper investigates the relation between stock performance and owner share retention in Swedish public equity listings during 2009 to 2013. The listings during the period are studied and divided into binary groups of "exits" and "non-exits", which are used in a statistical regression model to determine if there is a significant difference in average stock performance. The study finds that stocks of exit-companies on average significantly underperformed stocks of non-exit-companies during 2009 to 2013. Nevertheless, due to the limited number of observations available and the unusual market conditions, caution is required in interpreting these results..
Finansiella värderingsmodeller : En empirisk studie
This study tests two financial valuation models empirically by valuing three stocks from three industries, with the purpose of studying how well valuation models work empirically and to make a forecast. The models which will be tested are residual income valuation and discounted cash flow. Nine stocks will be picked strategically from the Swedish stock market and additional analysis will follow in the analysis chapter.Based on analysis and valuation, the commodities industry has decent valuation as the healthcare industry is undervalued thanks to the high valuation of AZN. The energy industry has low value due to the capital intensive nature of the industry. When it comes to the models and their practical implementation, DCF has been the most problematic to apply empirically whereas RIV was better but it still shows extreme values, which teaches the student the clear difference between theory and empiri..
Luft/luftvärmepump : - Med möjlighet till återvinning
Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.
Effekt av tillskott med isoflavonoider från sojabönor på LDL-kolesterol hos vuxna - En systematisk översikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Effects of isoflavone supplementation from soybeans on LDL-cholesterol levels in adultAuthors: Malin Blomgren Alegria and Ruut ReivaaraSupervisor: Lena HulthénExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-08Background: One of the most common causes of death in Sweden is due to cardiovascular diseases such as heart attack and stroke. Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.
LCC-analys av FTX-system : En jämförelse av centralt- och lägenhetsplacerat
This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.
Value creation form a gender perspective - a case study of Caran
Women ledaers and profitability, is there a correlation? Earlier research show different outcome on the correlation between women leaders and profitability. A Swedish consultant firm, Caran has a belief that more women leaders would create more financial profit, we ask us if that is the true situation. Using two different IC measurement methods we have shown the difficulties in calculate intagible resources, which methods that can/ can not be used and if women leders create financial value. We found the women leaders in Caran to add more value per dollar spent on the woman leaders than the value added per dollar spent on men leaders.

More specific, the aim of the study is to investigate if gender and generations react and feel differently towards the use of PoP TV-screens. From a practical standpoint, the study will aid marketers in how they can communicate more effectively with their target-market inside the store. In addition to this, the study will provide retailers with an insight into the overall atmospheric effect that the placement of TV screens has on stores.
Fynd av bakterier och svampar i blododlingar hos vuxna under år 2005 i Gävleborgs län : En epidemiologisk studie
AbstractIntroductionOccurrence of bacteraemia and fungemia is a serious condition with high mortality and the incidence is increasing worldwide. The aim of this study was to survey the occurrence of bacteria and fungi in blood cultures from adult patients domiciled in the county of Gävleborg during one year and also to calculate the incidence and mortality in the same geographical area.MethodThis is a descriptive epidemiologic study, based on all episodes of blood cultures analyzed at the Microbiology laboratory, Gävle hospital during 2005. Patients from 20 years of age, domiciled in the county of Gävleborg at the date of drawing the blood culture, where included in the study. Criteria of exclusion were negative blood cultures and cultures which were classified as contaminants.ResultsAltogether there were 4 564 blood cultures analyzed, resulting in 524 (11 %) positive cultures for further study. There were 442 patients (48 % women) involved in 499 episodes with confirmed bacteraemia or fungemia.
Filmkatalogisering: en behovs- och regelanalys
The aim of this thesis is to examine the characteristics of film cataloguing, and to compare general as in library use and specific as in archival use cataloguing rules. Most rules, both in archives and libraries, use the book as a point of reference. This is somewhat unfortunate on account of the great difference between books and films. The method used is studies of literature and qualitative interviews with three persons whose professional duties include cataloguing of films. The sets of rules which are studied are Katalogiseringsregler för svenska bibliotek KRS and The FIAF Cataloguing Rules for Film Archives.
Att tänka jämställdhet är en sak, att göra jämställdhet är en annan : En kvalitativ studie om hur biståndshandläggare beaktar jämställdhet i utredningar
The aim with this study is to analyze how Swedish social services interpret men's and women's needs and whether it is possible to discern any pattern in the social services investigations. The following questions are of importance: how men and women are described in the assistance investigations and if there are any differences between men and women in assistance investigations. The analysis is based on a qualitative text analysis of twenty assistance investigations. The investigations have been studied gradually and interesting patterns emerged which were analyzed by the theory of gender.The results are multifaceted and demonstrate on the one hand that men and women receive the help they apply for and the assessment of their needs is conducted in an equitable way. On the other hand, the study demonstrates that there is a difference in how men and women are described in the investigations..
Elevers tankar om klimatförändringar
This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.
Metod för dosoptimering av digitalt detektorsystem i klinisk drift
The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.
