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.
Osedliga verser och smutsiga barn : Barnavårdens praktik och begreppsanvändning under 1929-1937
Social work is a profession where documentation about people?s behavior and life circumstances is common. In the beginning of the essay we ask ourselves, if these descriptions about people can be problematic? To explore this, we studied social documentation, from the past. We used a historical source because history can help usunderstand the social work that is being conducted today.
Barnfamiljers tidsåtgång för matrelaterade hushållsaktiviteter : I relation till matvanor, socioekonomisk status och kön
Bakgrund Vi ägnar idag mindre tid åt hushållsarbete, där matrelaterade hushållsaktiviteter ingår såsom planering, inköp och matlagning, än för 30 år sedan. Barnfamiljer ägnar mer tid åt hushållsarbete, där matrelaterade hushållsaktiviteter ingår, och har svårare att hinna med allt som behöver göras i vardagen än andra samhällsgrupper. I tidigare studier har fokus inte riktats mot tiden barnfamiljer ägnar åt matrelaterade hushållsaktiviteter, deras matvanor samt socioekonomisk status.Syfte Syftet med studien var att undersöka tidsaspekter i relation till matrelaterade hushållsaktiviteter hos barnfamiljer avseende socioekonomisk status, kostintagets hälsosamhet samt ansvar relaterat till kön.Metod Studien genomfördes med en kvantitativ metod i form av en tidsdagbok och en enkät. Via Familjeliv.se och Facebook.se rekryterades åtta familjer till studien. Datamaterialet analyserades med Mann-Withney-u-test, Kruskal Wallis och Fischer?s exact test.
Hjälptyglars inverkan på hästen
The horse has been domesticated for several thousand years. It has gone from being used primarily for food and transportation, to become one of the most popular pets in Sweden. With over 150,000 practitioners, horseback riding is one of the biggest sports in Sweden and there is a variety of specializations to choose from. One orientation is western riding which is a broad sport with several disciplines where most originate in cattle work and other ranch tasks. Western riding is a growing sport in Sweden with an increasing number of practitioners and with many different organizations and associations, it is important that the correct knowledge of the equipment used is disseminated.
Artificial aids are available in a variety of designs and the most common variants used by western riders in Sweden is draw reins or some forms of martingale.
Biodiversitet av evertebrater på vegetativa tak
In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.
Fröskörd av hampa : metoder och tekniker för fröskörd av industrihampa
Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.
Vilka kvalitetsfaktorer anses viktigast vid inköp av grönsaker och frukt för återförsäljare i Sverige :
Since Sweden joined the European Union all Swedish fruit and vegetables are classified according to EU Quality standards. One important function is the product description and how it can facilitate the trade; for example in better comparing prices and also to guarantee the quality of the product. This quality standards or product descriptions are written as words of an Act and obligatory for all countries that has joined the EU.
It?s often a demand from the customers to be certificated according to some of many certificating systems. One example is the common worldwide GLOBAL GAP-certification system created by the organisation EUREP which represents the leading European retail traders.
Rött, vitt, svart - Vedisk kosmologi och klassificering i Ch?ndogya-Upani?ad 3:1-11 och 6
Chapter 6 of the Ch?ndogya Upani?ad has often been treated in works on early Indian philosophy, as well as in some comparative studies on color symbolism. Attempts to place it in a larger framework against the background of late Vedic religion are, however, few, the rationalistic and ?tradition-challenging? appearance of the text having repeatedly been emphasized. But the doctrine contained in the text ? a cosmologic teaching on the three elements constituting the universe, each being characterized by a color (red, white, black) ? and their microcosmic counterparts in the human body, does have some clear affinities to the worldview of the Br?hma?as and ?ra?yakas, which posits a series of similar correlations (bandhu-) between macro- and microcosmos.
Äldres resande i vardagen - Möjligheter, begränsningar och inställning till hållbara stadsvisioner
Everyday life mobility of elderly people ? opportunities, restrictions and sustainable urban visions aim to examine and describe elderly people?s movement patterns, their opportunities and restrictions of reaching high mobility and accessibility, and their attitude towards various sustainable urban visions. This paper is based on an approach of time-space geography as it covers the topic of movements in time-space, explained and developed using the concepts of mobility and accessibility. To examine elderly people?s attitude towards sustainable urban visions, this paper also takes approach on theories such as New Urbanism, mixed-use and the compact city.The method used in the study is an interweaving of a time geographic diary and qualitative interviews, where the respondents are six retired people between 68 and 77 years old living in Gothenburg city.

Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.
Problem med röda hamburgare efter tillagning : bakgrund och möjliga lösningar
Persistent pink in beef patties and hamburgers is a problem in the meat industry that has been known for a few decades. It is a costly problem as it can give rejections of food by consumers. Studies around the world have tried to solve the problem but it still remains a mystery. There are many different theories of what is causing the red colour. Some of the most likly theories are reducing hemocromes, high microbiological loads, contamination of nitrite or organic/non organic substanses, DFD meat etc.

Val av komplementmaterial för våtkompostering av klosettvatten
Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.
Flavour improvement of water solutions comprising bitter amino acids
The aim of this project was to improve taste of a liquid food product, comprising extremelybitter and unpalatable amino acids and one unrevealed ingredient. The amino acids were Lleucine,L-isoleucine, L-valine, L-threonine and L-lysine monohydrochloride. Experimentaldesign was set up as a screening of water solutions comprising these ingredients (called BCAAsolutions) and added ingredients with potential to improve flavour. BCAA solution withingredients that were potential bitterness suppressors were evaluated in flavour, bitternessand/or palatability. Solutions of separate amino acids were also studied.
Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus
Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.
