Cisterciensklostrens odlingar i Sverige under medeltiden
The aim of this paperisto find out which plants the Cistercian monks might have cultivated in Sweden during the Middle Ages and which types of plants it would have been practical to grow inside or outside of the Cistercian monastery precinct. Archaeologicaland archaeobotanical studies have been consulted to find out which plants were available in Sweden during the Middle Ages. Examples, mainly from Scandinavia, but also from the continent, are used to show that the monasteries were large institutionsthat had to feed a large number of people and that there would not have been enough space to cultivate everything needed within the monastery precinct.Secondary sources have in the main been used to gather this information, except in the case of the Swedish monastery of Nydala where F-Topo, a database developed by the County Museum of Jönköping,has been used to analyse the amount of land and the types of properties owned by the monastery.The conclusion is that for practical reasons the monks would have cultivated plants that needed to be close at hand, that were rare or delicate, that could not be stored for long periods and that were used in small quantities within the monastery precinct. This would include medicinal plants, herbs for cooking and some vegetables like lettuce, spinach,and similar,that do not keep well. Most other items, grains, cabbages, root vegetables, peas and beans could equally well be cultivated outside the walls.
Uppföljning av system för vägentreprenörer i skogen
Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development.
The study is largely based on interviews with road contractors that perform work for Holmen Skog today.
Selecting plant species for the occasion of the 300th anniversary of Carl von Linné at Möckelsnäs :
This report was an outcome of a cooperation between ?The Visitor and Knowledge Project Carl von Linné? and SLU, the Swedish University of Agricultural Science. The aim with the cooperation was to create a garden and to suggest suitable plants for an orangery already built. All species suggested should have a documented relationship with Carl von Linné. The project is located in the southern part of Sweden at an estate named Möckelsnäs not far away from Linné?s birthplace.
Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :
The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.
Fodder to ruminants within agroforestry systems in Rwanda - species and management
Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
Biologiska behandlingsmetoder för rening av rejektvatten från biogasproduktion
In this literature review the characteristics of two free-floating macrophytes, water hyacinth (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.
Towards a function for an Arabidopsis protein involved in sucrose dynamics
System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.
Risk för exponering av växtskyddsmedel i växthusmiljö
Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.
Vertikal trädgård i kallt klimat : en undersökning av ståndort, växtval och vinteraspekt
I takt med att städer förtätas och befintliga grönytor försvinner växer behovet av att hitta innovativa och fungerande lösningar för annan typ av grönska i städer. Utomhusväxtväggar har kommit att bli ett allt vanligare fenomen i södra Europa och andra delar av världen. I det bistra svenska klimatet är dock ståndorten på vertikala ytor att betrakta som extrem och vissa växter som trivs på det horisontella planet har inte en chans att överleva i det vindutsatta läget med stora temperaturskillnader. Detta arbete syftar till att underlätta växtvalet så att det blir möjligt att skapa såväl fungerande som estetiskt tilltalande utomhusväxtväggar i framtiden. Genom studier av litteratur på ämnet samt intervjuer med aktiva inom området undersöker detta arbete huruvida det finns gemensamma egenskaper hos de arter som faktiskt kan överleva under de tuffa förhållandena.
Resultatet påvisar att vissa samband i härdighet och naturståndort går att se men att många faktorer har betydelse för växternas överlevnad och att för få växtarter ännu testats.
Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets
This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.
Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv
The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.
Tidsmässig effektivitet vid produktion av ett plagg i finstickad trikå
Textilindustrin är en industri som ständigt växer och utvecklas. År 1995 introducerade det japanska företaget Shima Seiki den första maskinen med de tekniska egenskaperna, som gjorde det möjligt att producera ett trikåplagg med complete garment teknik. Denna introduktion revolutionerade tillverkningstekniken för dessa plagg. Denna studie har skrivits som ett examensarbete på kandidatnivå inom Textilingenjörsprogrammets avslutande del på Högskolan i Borås. Studiens huvudsakliga syfte var att undersöka vilket produktionssätt som var mest effektivt tidsmässigt vid produktion av ett plagg i finstickad trikå, ur ett supply chain perspektiv.
Kostnadseffektivisering i utvecklingsprocessen av specialemballage i bilindustrin
The automotive industry is a highly competitive market characterised by low profit margins or huge losses. Cost reductions have been of top priority for all OEM?s (Original Equipment Manufacturer) and will continue to be so for many years to come. Beside cost reductions, reducing the time-to-market is of greatest importance to stay in the competition. OEM?s that are slow to market with products that neither matches customer expectations nor the products of their competitors, will soon loose market shares and see their economical performance falter.
På spaning efter integration : En studie om integration mellan marknadsfunktioner och logistikfunktioner inom svenska detaljhandelsföretag
Bakgrund Tidigare studier belyser vikten av att företag integrerar marknadsfunktionen och logistikfunktionen, detta då en sådan integration leder till fördelar för företag. När funktionerna är integrerade kan företag bland annat möta kunders förväntningar vad gäller produkttillgänglighet och leveransservice på ett mer effektivt sätt än om funktionerna inte är integrerade. I dagsläget finns endast begränsade studier om hur integration mellan marknadsfunktioner och logistikfunktioner ser ut i praktiken. En empirisk kunskapslucka vad gäller integration mellan marknadsfunktioner och logistikfunktioner i svenska detaljhandelsföretag kunde således påvisas och det är dennakunskapslucka som legat till grund för denna studie.Syfte Denna studie syftar till att analysera om, och i så fall hur, marknadsfunktioner och logistikfunktioner inom svenska detaljhandelsföretag är integrerade.Genomförande För att uppnå syftet genomfördes intervjuer med medarbetare på marknadsfunktionen och logistikfunktionen inom tre svenska detaljhandelsföretag. Dessa företag var Cervera, Glitter och KappAhl.
