Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms
The past and ongoing structural change in Swedish agriculture has led to an increasing
number of large-scale farms. The biological factors associated with large-scale farming
operations may cause increasing variability, risk and reduced yields due to sub-optimal timing
and management of field operations. The theory of economies of scale suggests that largescale
production may benefit from lower costs due to scale efficiencies. Thus, large-scale
farms may face cost reductions in terms of long term inputs factors, e.g. agricultural
machinery.
Breeding practices of Red Maasai sheep in Maasai pastoralist communities
A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.
Markanvändningens förändring i vardagslandskapet : en analys av utvalda delar i Wessmantorp
During the last 100-200 years people have change their way of living and the condition and need for survival is no longer depending on the agricultural work. The forestry has replaced the farming and a lot of the natural pastural have been lost.
Wessmantorp in the north part of Skåne is an old place for forestry and farming where people have been living for several hundred years. Studies of selected parts of the everyday landscape, that earlier have been settlement with small crofter?s holding, show that the changes in the landscape mostly depends on the human factor and that a lot of the cultivable soil have been replaced with spruce. Some of the areas, which the earlier dwellings were placed, still contain some remains of old house foundations and stone fences and can regard as being of an historical value.
The studies provide the reader with a short background, the place as it is today and the changes of the land use in Wessmantorp.
Dagligvarumarknaden : en samhälls- och distributionsekonomisk analys av internet som försäljningskanal
Structural changes on the grocery market usually take place when the consumer is persuaded to take on the more labourintense parts of the distributionprocess. Internettrade changes this by causing competition between the unpaid work done by consumers and the labor performed by employees. In this master thesis grocery shopping on the internet is analyzed in a economic perspective with focus on distribution, changing marketstructures, driving forces and the future potential of internet as a saleschannel. The main conclusions are that consumerdemand and the belief in electronic commerceas a costreducing mechanism as well as a powerful new marketing tool were the driving forces behind the fast growth of grocery shopping on the internet. Electronic commerce introduces a new model of distribution with changing roles for consumers and grocerychains.

Påvisande av Helicobacter spp hos hund : en metodologisk studie
The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs.
Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.
Vindskador vid stickväg i 1:a och 2:a gallring i Boxholm, Östergötland : i stormen Pers fotspår
Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland
Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108
Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.
Klotter och skadegörelse : metoder och tekniker som förebygger klotter och skadegörelse i offentliga miljöer
The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.
"Det internationella kortet": En undersökning av det politiska samtalet kring Ålandsexemplet

Jakten på de optimala lösningarna : En vetenskaplig essä om förskollärarens ansvar och yrkesetik
Swedish childcare has undergone radical changes in the last 15 to 20 years. It has evolved from kindergarten to pre-school, in other words, gone from simple childcare to an active learning environment with the child as the center. Official documents, such as the pre-school curriculum and other guide documents, define the role and work ethics of the pre-school teacher. In my thesis I argue that it is essential to have an ongoing and continuous discussion at pre-schools on the practical applications of these frameworks and ambitious goals.What do you do when you simply cannot give every child the individual time they should have according to rules and regulations? How do you stay an active and present pedagogue in today?s pre-school with large classes and heavy workloads? How do you establish a common professional work ethics within a pre-school so that all children are treated equally? In my scientific essay, I examine these issues based on a real-life situation: Ellen in the hallway.A pedagogue must continuously make balanced decisions based on rules and regulations, on life- and work experience which, in many cases, contradict each other.
Allergifritt hus
This report consists of two parts, out of which the first deals with the planning and designing ofa small house in the Swedish city of Huddinge, using the weather conditions of the Swedish cityof Malmö. The house has to be in accordance with the Swedish building- and constructionregulations, as well as with the limitations in energy consumption given.The house itself has to consist of at least two bedrooms, and blueprints of the house, variousconstructional elements, ventilation, sanitation and electricity have to be drawn. Calculations ofthese aspects also have to be made, to ascertain that the different parts function as they should,and that the dimensions are sufficient.The second part is called ?Allergy free home?, and investigates how indoor climate affects us,and whether it has changed during the last few decades. It also makes an effort to see whetherthe increase of allergies and asthma is correlated with possible changes in indoor climate, andwhether technical solutions might help to handle or even decrease the issues arisen.
UNGA MÄN OCH DEMOKRATI : En fallstudie på en högstadieskola av teorin om unga män som demokratisk destabiliseringsfaktor
This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.
