The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems.
The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating season and the digestive tract is designed to digest forage efficiently.
Reglering av veka strukturer med multipla sensorer
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
Kapitalstrukturpåverkande faktorers inverkan på skuldsättningsgraden : - En branschjämförelse
Capital structure is without doubt one of the most frequently studied and controversial areas of modern financial theory, and will certainly continue to receive considerable attention from researchers worldwide. There is still no universal explanation of how an optimal capital structure would be designed for maximum appreciation, despite the development of several theories focusing on the subject. Equity and debt are the two main financing options that in combination explain the business's capital structure. The results of several research studies conducted in the subject has many times pointed out that there are specific factors that are directly related to the company's capital structure, and that there are clear sectoral differences in corporate debt. A study of the capital structure is considered important and interesting to implement due to the reasons above and the purpose of this study is to analyze and try to explain the similarities and differences between different industries in terms of how growth, profitability and size affect the debt level.
"Idag ska vi tälta på skolgården" : Ramfaktorers inverkan på friluftsundervisningen
The purpose of my study was to examine how teachers in physical education experience different frame factors impact on their outdoor education and their choice of didactic approach. My study is based on Lundgren´s frame factor theory and Peitersen´s didactic learning model. I have used a qualitative research method to answer my questions. I have been using semi-structured interviews to interview six PE teachers who all teach at high school level.Based on my results we see that the teachers experience teaching hours and class sizes as the frame factors that mainly affect the outdoor education. Teachers often choose to split up the outdoor activities into sequences in order to achieve better learning.
Värdedrivare i buyout-investeringar av noterade private equity-bolag - En empirisk studie av 15 svenska buyout-investeringar 1998-2012
Sweden is a world leader in listed private equity and ranked fifth in the world in market capitalization. The sector is attracting increasing interest from the investment community. However, the private equity industry in Sweden has historically poor reputation and is criticized for creating value through high leverage, multiple riding and severe cuts. This study analyzes value creation drivers in buyouts from the perspective of the private equity firm using a dataset of 15 realized buyouts by private equity firms listed on NASDAQ OMX Nordic Stockholm. The methodology used separates the value contribution of leverage on the private equity firm's return from internal operational improvements and external variations in transaction multiples.
Regimteorin i svensk kontext. Från Volvo till IKEA i Kalmar
The regime theory is the dominant paradigm in the studies of urban politics in USA. It provides a set of concepts to analyse the change from government to governance in the American local politics. The regime theory postulates that governing power in local government tends to be highly fragmented. The private sector has with its control of economic resources a major influence in shaping governing decisions. In this essay I study the regime theory in a Swedish context to investigate if the theory is pertinent when studying of Swedish local governance.
Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Tidskriftens väg till framgång : framgångsfaktorer för specialtidskrifter ur ett marknadsorienterat perspektiv

Instrumentbordets sterilitet
Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.

The field is in a Swedish context relatively unstudied regarding psychosocial health and the neighbourhood. Aim: The study aimed to examine how social planning can affect the health of individuals. The focus areas were contextual and compositional factors related to individuals' psychosocial health and the contextual risk- and health factors that exist in the neighbourhood. Method: A literature-based study was conducted and 15 scholarly articles form the basis for analyse.
Röstningsbeteende i utsatta bostadsområde : En studie om hur social miljö påverkar valdeltagande
Already in 1988, different levels of participation in the election between different districts of big cities in Sweden were noticed. The problem with low political participation in specific areas has almost always been theoretically explained through an individual perspective. This study is therefore focusing on the problem from a contextual perspective. The hypothesis for the study is as follows, in the case of Malmö the level of participation in elections are affected by social environment in which segregation will be the single highest factor. The dependent variable, participation in the election was tested by the independent variables representing social environment; origin, education, gainfully employed and income.
Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt
Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.
Pulveregenskapers inverkan på grönkropp med avseende på sprickor
This thesis is a survey and also an investigation of the different factors that affects the cracking that occurs in the inserts at AB Sandvik Coromants production in Gimo. The work that has been done has focused on two main factors, namely, powder characteristics and pressing parameters.AB Sandvik Coromant produces tools and tooling systems for metal cutting. They have some problems in their production of inserts. The problem is that cracks sometimes occur in the body of the insert, after it´s pressed. In order to investigate this, a preliminary study was made in which production principles were studied.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
STC-Plant Growth and Development, utvärdering av ett läromedel
Denna uppsats är skriven höstterminen 1997, då ett nytt läromedel började utvärderas i Linköping. Den svenska skolan har sedan en tid haft bristande natur- och teknikundervisning i de lägre årskurserna. Den Kungliga Vetenskapsakademien gav vissa av Linköpings skolor uppdraget att i lärarlag arbeta med ett nytt material, för att kunna se dess fördelar och brister. Materialet heter Science and Technology for Children (STC) och är framtaget av den amerikanska organisationen National Science Resource Center. Sedan utvärderingen av STC har läromedlet bytt namn till NTA (Natur och Teknik för Alla).
