Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :

It is important for today?s farmers to minimize the costs for crop establishment, because of decreased prices and support from the EU. Farmers, who plow in autumn on heavy clay soil, often do some kind of tillage in autumn to get better soil structure before spring seeding. This is especially important when growing small seed crop, e.g. sugar beet and oil plants.

Det sviktar - en litteraturstudie om hjärtsvikt

Allt fler personer drabbas av hjärt- och kärlsjukdomar, vilket på sikt kan leda till kronisk hjärtsvikt. För att förbättra omvårdnadsåtgärder för hjärtsviktspatienter har Socialstyrelsen 2004 givit ut nationella riktlinjer för hjärtsjukvård där vikten av en individuell handlingsplan betonas. Syftet med litteraturstudien är att undersöka på vilket sätt sjuksköterskor utför omvårdnadsåtgärder avseende fysisk aktivitet, egenvård, nutrition och rökstopp för patienter med hjärtsvikt och om dessa överrensstämmer med gällande riktlinjer samt om hänsyn måste tas till genusskillnader. Metoden är en litteraturstudie i databaserna PubMed och Elin@Malmö vilket resulterade i 14 artiklar som användes för att söka svaret på syftet. Som teoretisk referensram har Antonovskys KASAM modell använts.

Lantbruk i framtiden : ett praktikfall

The economic prerequisite to many farmers in Sweden after the EU membership and the new agriculture policy has generated large demands on the farm management. Until year 2004 you got a grant based on what you had produced and not on consumer demand. In 2005 a new economic aid (Mid Term Revue) was introduced and the conditions has changed again. Due to this I have chosen to do a cost-benefit analysis on a case, to investigate if the present production is sustainable in the future. My conclusion is that the profitability is acceptable even if the farm has a high debt. But to make the production more profitable the products produced should be refined as much as possible at the farm, to get maximum economic return.

Träningsinducerad lungblödning hos trav- och galopphästar

Träningsinducerad lungblödning, Exercise-induced pulmonary hemorrhage (EIPH), är ett stort problem hos travare och galoppörer i hela världen. Det får anses klarlagt att mekanismen bakom EIPH är så kallad stress-failure, utmattningsskador, i blod-gasbarriären vilket beror på att hästarna har en respiration och cirkulation som ger extrema påfrestningar på denna sköra struktur. En bidragande faktor till stress-failure tycks kunna vara att hypertension i lungvenerna leder till att dessa remodelleras och förtjockas, vilket i sin tur leder till ännu högre tryck i lungkapillärerna. Den här litteraturstudien handlar om hur inflammation i lungorna kan ge upphov till EIPH. Inflammation finns med i problematiken runt EIPH både som en bakomliggande faktor och som ett resultat av blödningen.

Överlevnadsanalys i tjänsteverksamhet : Tidspåverkan i överklagandeprocessen på Migrationsverket

Migrationsverket är en myndighet som prövar ansökningar från personer som vill söka skydd, ha medborgarskap, studera eller vill jobba i Sverige. Då det på senare tid varit en stor ökning i dessa ansökningar har tiden för vilket ett beslut tar ökat. Varje typ av ansökning (exempelvis medborgarskap) är en process som består av flera steg. Hur beslutet går igenom dessa steg kallas för flöde. Migrationsverket vill därför öka sin flödeseffektivitet.

Kategorisering av faktorer som påverkar flödeseffektivitet - En fallstudie på Capio St Görans Sjukhus

Swedish healthcare is in continuous need of cost savings and efficiency improvements in order to meet the increased demand for care. The theories of lean, developed from the industry, are applied more frequently on healthcare systems to increase effectiveness and reduce waiting times in patient processes. However, some processes seem to be more successful in their lean implementation than others. In this thesis, factors influencing flow efficiency in lean healthcare are examined. Through interviews with the top executive board at Capio St Göran's hospital, data is collected in order to analyze reasons for success.

Evaluation of tools for analysis and quantification of Fusarium mycotoxins

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Lönsam produktion av stärkelsepotatis : timing och skördeanpassade åtgärder

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Svampar associerade med raps : betydelse för uppkomst och grödetablering

Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems. This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens. The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.

Bredspridning av grönmassa :

There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.

Colombia - en fallerad stat? En teoriprövande fallstudie av Colombias statstatus och en kritisk granskning av teorierna kring fallerade stater

Väpnade aktörer, terrorism och illegal handel (med människor, narkotika och vapen) är alla företeelser som, i varierande omfattning, florerar i fallerade stater. Dessa företeelser återfinns inte minst i Colombia, som trots det inte bedöms vara fallerad.Uppsatsens syfte är att påvisa behovet av kvalitativa och kontextspecifika studier, då vår förförståelse är att analyser av fallerade stater, som bygger på kvantitativ forskning, missar orsaksperspektiven. För att göra detta prövas två teorier (Rotbergs kvantitativa och Buzans/Holstis kvalitativa) på fallet Colombia.På grund av att Rotbergs teori har en lägre validitet och inte förklarar vad som ligger bakom staters interna problem, kan Colombias situation mest framgångsrikt förklaras utifrån Buzans/Holstis teori. Buzan/Holsti missar dock flera för, Colombia centrala aspekter, som går under benämningen ?the Hidden Form of State Failure?.Nyckelord: Fallerade stater, Rotberg, Buzan/Holsti, Colombia, ?the Hidden Form of State Failure?..

Distribution of wild boar (Sus scrofa) damage and harvest loss in crop fields

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

Skördemetoder av industrihampa :

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.
