Driva tulpaner i näringslösning eller i jord :
The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands.
There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.
Standardiserat arbetssätt för kunskapsprocesser : ? En fallstudie på en prototypverkstad
In recent years, Lean has been implemented in a variety of companies with focus areas that differ from the conditions that characterizes manufacturing. This transfer has contributed to fairly superficial results because companies almost exclusively focus on Toyotas methodology and not on the goal of Lean. The effort of transforming Lean from manufacturing to any organization requires a definition on a general level and a view of Lean as a system. One of the core principles of Lean and the foundation of continuous improvements is standardized work. In product development there is a negative view on standardized work, where the engineers state that the principle is not applicable for knowledge processes that include non-repetitive and creative work.In the framework of this master thesis literature has been studied to find support that standardized work is applicable for product development and areas that include knowledge processes.
Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd
Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method.
This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.
Undervegetation : användning av vedartade marktäckare i anläggning
The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull.
The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.
I den bästa av världar. En reflekterande uppsats om åtgärder för lesbiska och bisexuella kvinnors marginalisering inom sjukvården.
AbstractDet har i ett antal internationella undersökningar framkommit att HBT- personer har sämre hälsa än heterosexuella. I den förbindelsen har syftet med denna uppsats varit att diskutera kring vilka åtgärder som är möjliga för att förändra denna ohälsa, där jag har koncentrerat mig på särlösning kontra integrationsteorier. Jag har inriktat mig på lesbiska och bisexuella kvinnor inom HBT- området. Med hjälp av Nancy Fraser och Iris Marion Youngs teorier om erkännande eller omfördelning diskuteras särlösningen och integreringens fördelar och nackdelar. Problemet är att det vid särlösningar finns en risk för att lesbiska och bisexuella kvinnor fasthålls i sin marginalisering och att det inte arbetas med roten till problemet.
"De tycka emellertid av gammal vana att det smakar gott, och tro dessutom att det är bra för hälsan" : samiskt växtutnyttjande från 1600-talet fram till ca 1950
Meat and fish was the most important food for the Sami people in northern Scandinavia until the beginning of the 20th century. It is not so well known that the Sami people also used a lot of wild plants as food and medicine although that kind of food was relatively common among them until the end of the 19th century. The purpose of this master thesis has been to describe which plants the Sami people used in general and also which plants were the most commonly used, and when and how these plants were harvested. I also wanted to measure the quantities of Angelica archangelica and Rumex acestosa within traditional harvest sites. Furthermore I wanted to find out if the plant use differed among Sami groups geographically.
Nursing technique and growth environment of Rabbit fish (Siganus guttatus) in the area of Tam Giang lagoon, Thua Thien Hue
SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.
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.
Journalistrollens rivaler : Om public service-reportrars syn på sin roll i relation till användarskapat innehåll och medborgarjournalistik
Journalists´ role in society has traditionally been of representative nature with a task to distribute news and scrutinize those in power. But technological changes have created a new publishing world outside the traditional media institutions. In today?s redactional society anyone can become a publisher in a blog or through other channels on online. This process can be seen as contributing to increased democratization giving everyone the opportunity to publish.
Produktivitet vid stubblyftning :
Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.
Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan
The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.
Förekomsten av rotknölsbildande bakterier för Brun böna (Phaseolus vulgaris L.) och Blå lupin (Lupinus angustifolius L.) i olika jordar
Kvävgas kan inte tas upp direkt av växter men genom biologisk kvävefixering kan vissa symbiosbildande bakterier omvandla kvävgas till ammonium. Med bakteriens hjälp kan en växt tillgodogöra sig ammonium och på så sätt bilda protein. Ett exempel på denna typ av symbios är den som kan uppstå mellan en särskild grupp av bakterier, Rhizobium ssp och baljväxter, så kallad rotknölssymbios. Detta är ett exempel på en ekosystemtjänst, en fördelaktig interaktion mellan växt och mikroorganism, som gynnar alla parter, inklusive människan som odlar baljväxten. Hur allmän förekomsten av Rhizobium genotyper är i svenska odlingsjordar är ej klart dokumenterad och därför är frågan om behovet av inokulering av utsäden fortsatt aktuell.
Skaftslamkrypa (Elatine hexandra) i Bolmen, utbredning, tillväxt, reproduktion och styrande faktorer
The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.
Stubbehandling med pergamentsvamp och urea mot sporinfektioner av rotticka i bestånd av hybridlärk
Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.
Skogsbrukets erfarenheter av Poppel Populus sp. i Skåne :
In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species.
The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.
