Hur påverkasogräsuppkomsten av jordbearbetning :

Today it is common to spray against most weeds by using very expensive weed-killers. The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers. Therefore it is in everyones interest to find other methods to fight the weeds. Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose. Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%. To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night. By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

Ungas syn på integration : En kvalitativ studie om invandrarungdomars syn på integration

The aim of this essay was to acquire an enhanced knowledge about young immigrants? point of view of integration. During a former practical training semester I became interested in what the young immigrants thought about their own integration, what their conception was about this issue. I found that it had different meaning to different persons, to some it meant assimilation, to others it meant being able to interact with the opposite gender. To examine this I used interviews and interviewed an amount of young immigrants in different stages of their studies in Swedish.

Avveckla eller utveckla mjölkproduktion : vilka faktorer påverkar beslutet?

The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased. In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.

Windows, RedHat och IPv6 : ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

"Det adopterade barnet" : Konstruktionen av adoptivbarn i barnlitteratur

With the increasing number of adoptees in Sweden, so has the amount of literature regarding different aspects of adoption. The aim of this study is to explore the construction of adoptees in children's literature. It takes on a social constructionism view, by regarding language as a narrative tool in which human beings construct versions of different phenomenon. By exploring the different discourses in the data within the context adoption, we can identify different versions of "the adopted child" and their needs as it is constructed in the literature. Also, by putting them in a bigger context, we are allowed to see the social structures and the discursive conditions that allow a certain child perspective of "the adopted child" to take place.

System 348 - Rekombinator : Analys av reglerproblematik vid O2

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

Indexering av skönlitteratur ? en konsistensundersökning

The aim of this master thesis was to measure the terminological consistency when indexing fiction. The study included ten participants, five librarians and five patrons who indexed two novels in three steps. Besides calculating the terminological consistency a typified index based on the term frequency was created.Subject heading list Att indexera skönlitteratur was used as a controlled vocabulary and to calculate the consistency the asymmetrical formula was used.The result showed that the study produced relatively high consistency values compared to other studies. The subject heading list increased the consistency value for all of the participants, for the patrons the increase was substantial. The librarians produced higher consistency values compared to the patrons in almost every step and they had in percentage lower amount of terms used only once..

Estimation of heterosis and performance of crossbred Swedish dairy cows

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.

Värmepumpars inverkan på elkvaliten

Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..

Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

Råvaruinflöde inom träindustrin : En fallstudie på ett norrländskt pappersbruk

Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

Varför tillåter Gud det onda? : En jämförande studie av C.S Lewis och John Hicks tedicéer.

Abstract The amount of evil that we can see in our world might make the thought of a kind and caring God as its creator paradoxical. This is what is generally called the problem of evil and the topic of this study. This is a litterary study which is based on qualitative analysis and hermeneutics as our method. We have chosen to research this problem with the emphasis on two different theodices. One of these theodices is written by John Hick and the other by C.S Lewis.

Kapacitetsberäkningsmodell för materialhanteringsflödet på Ericsson i Kumla

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

SJ-syndromet - en fallstudie om en intensiv medierapporterings inverkan på en organisations anställda

Media and social media have been proved to occupy an increased amount of time in people's everyday lives and affect how individuals interpret reality. This phenomenon is referred to as the medialization and its implications on organizations and their members become important to understand. The purpose of this study was therefore to examine how members of an organization under intense scrutiny from the media are affected by this exposure in their everyday work. To gain knowledge about the area a qualitative case study was performed on the Swedish train operator SJ AB - one of the most media exposed organizations in the country. A theoretical framework is developed for the study and discusses organizational identity, stigmatization and motivation.
