Påverkar suggors grymtande under digivningen smågrisarnas tillväxt? :

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

Nyttoforskning. En studie av den svenska forskningsfinansieringen för humaniora och samhällvetenskap med Riksbankens Jubileumsfond som exempel.

In this paper I argue that the development of innovation ideas within the financial system of scientific research might have a counterpart within the financial system of the social sciences and the arts. The ideas of innovation share a common way to evaluate science in terms of how well it can contribute to economic growth. In the past two decades a similar development can be observed within Riksbankens Jubileumsfond (RJ), one of the largest external financiers of the social sciences and the arts in Sweden. The idea of evaluating research used by the innovation ideas has grown popular within RJ, only it seems they evaluate research in terms of how well it fits into an international research community rather than how much it can contribute to economic growth as is the case within the innovation ideas. By examining the different ways of financing research that RJ has used during the last 2 decades, this paper aims to introduce a new perspective in which it is possible to understand the development within this type research funding as a part of a bigger system of development..

The contentious nature of war : an analysis of military theorists

The purpose of this essay is to investigate and assess, with Clausewitz?s theory as thebackground, how different military theorists interpret and relate to the nature of war.This essay illustrates the state of research into Clausewitz?s philosophical influences.Clausewitz?s theory of the nature of war is subjected to a qualitative text analysis that is followedby a critique of other military theorists interpretations of his theory. Subsequently a descriptive,comparative qualitative text analysis is performed where the factors identified by Clausewitz asbeing part of the nature of war (?rational thought?, ?passion? and ?chance?) are used as a meansto interpret and assess how other military theorists relate to Clausewitz theory. This essay ismainly founded on analysis of the works of Jomini, Delbrück, Fuller, Liddell Hart, Handel,Roxborough, van Creveld and Keegan.

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Är bor nödvändigt vid skogsgödsling i Sverige?

This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.

Det är ju logiskt, men det är väldigt ologiskt om man jämför med allt annat logiskt.? - En studie om elevers syn på ämnet Gehörs- och musiklära.

Title: "It is logical, but not logical at all compared to every other logical thing." - A study about how students in upper secondary school reflect about their studies in Pitch and music theory.Pitch and music theory is a compulsory subject for music students in the art programme of upper secondary school of Sweden. The aim of the subject is to develop the students? knowledge about music theory concepts in order to help them play and create music on their own. The aim of this paper is to discuss how students talk about ear training and music theory. Qualitative group interviews were carried out with two student groups from the first and second year of the upper secondary school.

Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden

Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

Kostnadsbesparingar på EM7 : Omkonstruktioner för billigare tillverkning

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

"Evolutionen är ett syfte" : en studie av elevers världsbilder angående evolutionsteorin

In this thesis swedish students? worldsviews, in relation to the theory of evolution, were studied. Thirty students from two different schools and cities took part in the survey and four students were later chosen for interviews. The results showed that there are many different types of students and categories in this matter. The study also showed that for some religious students, accepting the theory of evolution was not difficult thus showing that religious students can both believe in God and in the theory of evolution..

Funktionaliteten i skogsmaskiners GIS-system

Holmen Skog is currently using a GPS-program called TraktInfo, originally developed within the company. They are now planning to switch to a new GPSprogram or allowing the contractors to buy other programs available from the logging equipment manufacturers. To be able to offer this flexibility, Holmen Skog needs to obtain information about the features offered by the different manufacturers in their specific programs, and also when the manufacturers are planning to start selling programs adapted to the new standard called StanFord2010. According to the study, the manufacturers are hesitant to StanFord2010 and there has also been a lack of clear signals from the customers and clients about what kind of different new features to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester?s path by creating a ?log plot?. This feature was not used to its full potential however, since only one out of eight of the forwarders included in the study had computers that were compatible with the harvester?s computer.

Hur ska vi komma vidare? : frågor rörande neolitiseringen i Sydskandinavien

This paper deals with the question of neolithisation of Southern Scandinavia. The main goal is to give an overview of three theories regarding how agriculture and livestock breeding was introduced to the Southern Scandinavia. These are as follows: the immigration theory, the socio-economic theory and the historical explanation theory. Furthermore it is investigated which theory has the most probably support in material culture. There are obvious difficulties in interpreting the archaeological material.

Impact of Regulations on Innovation Performances in EU:

Innovation has been identified as one of the key factors for economic growth long ago. However, the emergence of ?knowledge century? further strengthened the role of the concept since proper management of the knowledge is essential to make the best out of the innovative capacity of the companies as well as the countries. This necessitates a balanced intellectual property rights (IPR) systems, since these rights provide the basis to solve the market failures faced by innovating firms by creating property rights over knowledge. There is an inherent dilemma between invention and diffusion.
