Ny teknik för kombisådd :
The use of combi-drilling during spring tillage has become very common in southern
Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant
nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very
widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and
seed coulters, which means that the draught requirement is relatively high. It thus
requires large, heavy tractors, which compact the soil and are comparatively expensive to
buy and run.
A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish
market.
Djup icke vändande bearbetning i sockerbetsodling :
A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator.
On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different
treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard
ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary
cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm.
The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle.
Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined.
The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.
Förskrivning av antibiotika till hund vid veterinärhögskolan i Nantes, Frankrike :
The purpose of this retrospective study was to investigate the prescription of antibiotics to dogs at the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France. The purpose was also to compare the possible prescription patterns in France with those seen in a similar study by Petersson (2003) at the small animal clinic at the Swedish University of Agricultural Sciences, Uppsala.
Antibiotics are very important in veterinary medicine and are used both to treat infections and to prevent them. The use of antibiotics however is not without complications and the risk of developing antimicrobial resistance is of most concern. Resistance has been shown to exist against all currently known antibiotics and potentially all pathogenic bacteria could develop resistance to one or more antibiotics.
This study analysed the case records for all dogs presented to the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France during October 2001 and March 2002 to identify patients which were treated with systemic antibiotics. For these cases the antibiotic used, classified according to the ATCvet system, and the indication for use was noted.
A total of 292 cases (146 per month) resulted in administration of systemic antibiotics.
Med Säkerhetsrådets resolution 1325 (2000) som utgångspunkt : En komparativ studie av två handlingsplaner
Security Council resolution 1325 (2000) is about women, peace and security. Since the resolution was adopted several countries has made their own National Action Plan for implementation of the resolution.Sweden and Denmark are two of these countries. Resolution 1325 is one of the documents that each countries armed force has to relate to in international work.These countries can get to work together in international operations within the framework of the Nordic Defense Cooperation, NORDEFCO. This study is done by looking at similarities and differences in the action plans and whether they can be an obstacle for the countries to cooperate in an international operation.In this paper a comparative analysis of Sweden and Denmark's plans for the Security Council resolution 1325 will be done. The comparison is made based on the clauses of the resolution relating to the member states actions.In this paper, a qualitative text analysis to be carried out with sections of Resolution 1325 as a model for the comparison..

Användning av konst i samspel med landskapsarkitektur : med utgångspunkt i Gunilla Bandolins och Olafur Eliassons verk
The relationship between landscape - public - art and whatoccurs and happens in between is what this paper casts light on. The essay intends to investigate whether there is any boundary between landscape architecture and art. How does this border looks like? Can art in the context of landscape architechture lead to a closer cross-border collaboration between landscapearchitects,artists and the public, to create attractive and/or functional outdoor environments. The place where the meeting can take place is outdoors where the landscape architect works, in the public environment and around the public art.
Svartrost, Puccinia graminis f. sp. avenae, epidemiologi och bekämpningsstrategier i Mälardalen
Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.
?Men de används ju inte.? - en undersökning om distributionsstödda böcker från bibliotekariers synpunkt.
The purpose of this study is to investigate librarian?s opinions concerning literature with state supported distribution and how to mediate and market these in the library. The types of mediation and marketing that have been studied are positioning, labeling and oral mediation.The study is qualitative with interviews at seven main public libraries in central Sweden. The respondents of the study were responsible for the literature with state supported distribution within the library.The study is based on a theoretical frame of reference containing theories from Jofrid Karner Smidt, regarding librarian?s mediation in libraries, and François Colbert?s theory on marketing planning for arts and culture.The results of our study showed that librarians have both positive and negative opinions when it comes to the literature with state supported distribution.
Manöverkrigföring : en stagnerad eller utvecklad teori?
Manöverkrigföring är ett vedertaget begrepp inom militär teori. Jag har i denna uppsats valt att analysera och jämföra två operationer som baseras på manöverkrigföring.Vid Tysklands invasion av Frankrike 1940, Fall Gelb, utgjorde manöverteorin grunden för operationen. Detta var första gången som manöverkrigföring utnyttjades i stor skala för att slå en jämbördig motståndare. I den USA-ledda FN-koalitionens invasion av Irak 1991, Desert Storm, var manöverkrigföring ännu en gång den operativa huvudteorin i planerna för operationen.Den här uppsatsen är en komparativ fallstudie baserad på kvalitativ textanalys. Båda operationerna beskrivs för att sedan jämföras varvid skillnader och likheter belyses.Resultatet visar att såväl Fall Gelb som Desert Storm genomfördes som operationer baserade på teorin om manöverkrigföring, men att stora skillnader finns mellan dessa operationer. Orsaken till skillnaderna belyses till del och vissa teorier om vad dessa beror på presenteras..
Stubbtransporter och bränslekvalitet hos stubbved :
Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.
Maskulinitetskonstruktion inom svensk kommunal räddningstjänst : En studie kring föreställningar om kvinnliga brandmän och brandmän med utländsk bakgrund
This essay is a qualitative study about Swedish fire-fighters´ ideas of women and people from other ethnic backgrounds than Swedish. The problem in focus is why there are difficulties for those groups of people to be employed in the Swedish fire service. Can there be ideas of these groups which are not favourable for them? And if this is the case, can those ideas be explained by gender theory about construction of masculinity? The purpose is to investigate whether the absence of women and people from other ethnic backgrounds can be explained by the fire-fighters´ ideas of those groups. The study consisted of a one day observation and four one hour long interviews with fire-fighters from different positions within the Swedish fire service.
Poultry producers? perceptions of changing market conditions : a field study of the poultry production in Khartoum state of Sudan
Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999).
The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.
