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.

Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

Evaluation of four methods for the assessment of joint swelling in dogs

Evaluation of joint swelling is an important part of the orthopedic examination and can be used to follow a patient?s progress during rehabilitation and therapy. Usually a swelling is assessed by palpating the joint but a more objective, but still easy to use, method would be preferable.This study seeks to increase the knowledge in veterinary rehabilitation by validating four different measurement tools (three recognized and one novel) for the assessment of elbow joint swelling: palpation, tape measure (circumference and figure eight measurement), slide caliper (craniocaudal and mediolateral positioning) and tonometer. This was achieved by calculating the inter- and intra-rater reliability and correlating the results from the different measurements with each other.The methods with best inter- and intra-rater reliability as well as good correlation among themselves were shown to be slide caliper with craniocaudal positioning, circumference and figure eight. Additional studies, with a larger and more diverse material, ought to investigate these methods further..

Osteometriska Mätningar : För artbedömning av får, get och svin utifrån mått av revben

Ribs from sheep, goat and pig are rarely assessed  to species due to the fact that they are very similar in their morphology and size. The ribs are instead considered unidentifiable although it is possible to see what kind of bone it is. If these ribs would be identified to species not only would species assessment degree of archaeological source material   increase, the relationship between meat-rich and meat poor regions would change.To find out whether there are morphologically measurable differences between sheep, goat and pig ribs, three measurement points on each rib has been defined and measured. At each measurement point two measurements were measured, one medial-lateral measurement and one cranial-caudal measurement. The ratio between the medial- lateral measurement and the cranial-caudal measurement was calculated for each point.

Finansiering av arbetsintegrerande sociala företag : En dragkamp mellan det sociala och det kommersiella

The field of the social economy and of the work integration social enterprises (WISE) in particular, is for many a more or less unknown area. Unlike ordinary enterprises the WISE's are different due to their aim of integrating disadvantaged people through work. In comparison with other small enterprises earlier research has shown that the WISE's are dealing with challenges regarding recruitment, participation, leadership, sustainable business ideas but above all, the access to funding. The purpose of this essay has therefore been to examine and analyze the financial situation of eight WISE's located in the Stockholm County. The results indicate that half of the enterprises perceive their economic situation as very unstable and as an obstacle to their further development.

Implementation av ett kunskapsbas system för rough set theory med kvantitativa mätningar

This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.

Fem-studie av rörelser i planet mellan bakaxelbrygga ADA1100 och centralväxelhuslock R780

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

Uppsats f?r avl?ggande av filosofie kandidatexamen med huvudomr?det kulturv?rd med inriktning mot bebyggelseantikvarisk verksamhet 2024, 180 hp Grundniv? 2024:03

Local cultural environment planning in Sweden often comes to rely on municipal heritage plans. These plans are meant to facilitate management of local cultural values, work as a tool for local planning and increase awareness of cultural environments for the public. In the last decades public participation in planning has become more and more of the ideal strategy, challenging the idea of cultural environment planning as an expert-led field. The idea of the field as one that implicates public participation as a strategy has been fortified in Sweden through national goals, government bills and conventions. Nevertheless the implementation of public participation in municipal heritage plans remains quite uncharted. The aim of this study is to explore public participation in regards to how municipal heritage plans are developed and the perception of public participation in cultural environment planning amongst professionals, comparing bigger and smaller municipalities.

Design och tillverkning av en stereoanläggning med aktivt delningsfilter

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

Bäddodling av matpotatis :

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
