Anlockning och gnag av snytbaggar (Hylobius sp.) : effekt av plantstorlek och behandling med metyljasmonat

Two field experiments were conducted in central Sweden in order to: 1) Determine a relationship between the number of approaching pine weevils (Hylobius sp.) and the number of attacks by pine weevils, in relation to the size of seedlings of Scots pine (Pinus sylvestris). 2) Determine if application of methyljasmonate (MJ) on seedlings of Scots pine will result in higher resistance towards attacks by pine weevils and/or have any effect on the number of approaching pine weevils. The field experiments were designed with two separate parts in close vicinity on the same clear cuttings: a) pitfall traps placed in patches of scarified soil that caught approaching pine weevils at 2.5 cm from the bait, which consisted of different sized seedlings of Scots pine some of which were subjected to application of MJ and b) the same type of seedlings planted out in patches of scarified soil. The first field experiment was conducted on a 1-year old clear cutting outside Uppsala in east central Sweden and the trapping part of the experiment consisted of 8 blocks with 6 treatments: 1) control, 2) small over-wintered seedling, 3) medium sized seedling, 4) medium sized seedling treated with 0.5 ml 100 mmol MJ 4 days prior to start of experiment, 5) large seedling, 6) vial with 9.5 ml of ?-pinene. The trapping experiment lasted for 6 weeks in the early summer.

Biogasrötning av socker- och foderbetor : Jämförelse av färska, stuklagrade samt ensilerade betor i laboratorieskala

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

Passagerarnas attityder till säkerhet och risker på en finlandsfärja : -en fortsättningsstudie över attityder om säkerhet när turisten färdas på världens vackraste motorväg, utan att ens hålla i ratten

Det finns vissa risker förenat med att vara resenär ombord på en färja. Att resa med ett passagerarfartyg har mer och mer utvecklats till en fritidsaktivitet där själva resandet ofta är av underordnad betydelse. Tidigare forskning visar att cirka 13 procent av passagerarna inte tar till sig den allra viktigaste säkerhetsinformationen. Attityden bland passagerare verkar vara en något likgiltig inställning till säkerhetsinformation, trots tidigare olyckor. Syftet är att studera passagerarnas attityder till säkerhetsinformation ombord på en nattfärja som trafikerar Sverige-Finland.

Beijers Park i "Parkernas Stad" : 125 års parkhistoria på Kirseberg i Malmö

To perform a historical record of Beijers Park's development to date is about securing the tracks back in time. The historical record about the park tells not only the history of the park but the city, district, local residents and art of gardening. As the historical story is documented the necessary base for establishment of any care plans in the future and the base for cultural and historical value the park is made. Beijers park can in such work be treated alone or as part of the context of parks that were built during the same era in Malmö's history.Beijers park origin from the era of the late 1800s, when the entire green structure in Malmö changed. The park area today covers 12 hectares and is located in the district Kirseberg.

Wetland development in the context of ecotourism : a conceptual design proposal for a wetland site in Lake Victoria, Kenya

The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning social system and good resources to manage the problems and take advantage of the opportunities that the tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes conservation of the environment and improves the welfare of local people is what defines ecotourism. A concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back, without risking creating imbalances in society. Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.

Ligghall för utegångsdjur ? en sammanställning och analys av domar i djurskyddsärenden som handlar om ligghall till utegångsdjur åren 2007-2013

There is currently an ongoing discussion in Sweden about the need for weather shelter for farm animals being kept outdoors during the winter season. Currently, the national animal welfare legislation requires weather shelter providing the animals? with access to a dry and clean place to rest, but under certain conditions exemptions can be granted. The Swedish Board of Agriculture has put forward a hypothesis that there is a difference between judicial decisions in animal welfare cases dealing with weather shelters, as to whether the animal has shown to be suffering or not. The aim of the study was to highlight any weaknesses or difficulties when assessing animal welfare issues associated to the absence of or design of weather shelters.

Den kommunicerande forskaren : Forskares tankar kring och arbete med forskningskommunikation

As the western society gradually turns into a knowledge- and risk society, where science and scientific innovations increasingly both promise to save the world and destroy it, a shift in the relation between the scientific community and the rest of society has emerged. A shift from a top-down one-way transfer view regarding communication, to a dialogue-based interactive co-production model, where the public are part of setting the agenda for research and contribute to the knowledge production. Or at least in theory, in EU documents and in many different country's policy documents. In practical application however, one might have a hard time see the implementation of such model.As a more comprehensive and dialogue-based science communication is depending on the possibility for scientist themselves to engage and fell the need to engage, we have focused on their thoughts.In this thesis we have examined six scientists view on, and work with, science communication, as well as their perceived social and structural conditions. We have also examined action plans and strategy documents from three Swedish universities that in different ways mention science communication and interaction with the broader society.

Påverkar järninjektioner risken för ledinflammationer hos smågrisar? :

Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.

Kattegattleden : ett gestaltningsförslag för rastplatser längs med Sveriges första nationella rekreations- och turistcykelled

Rekreationscykling och cykelturism ökar i takt med ett växande intresse för hälsa, miljö och fysisk aktivitet. Cykling ligger i tiden och flera länder i Europa har de senaste åren satsat på nationella turistcykelleder. Kattegattleden kommer att bli Sveriges första nationella cykelled för turism och rekreation. Leden kommer att sträcka sig från Göteborg till Helsingborg och väntas bli ett besöksmål för såväl lokalbefolkning som nationella och internationella turister. Arbetet med att förverkliga leden har pågått under många år och har inneburit ett samarbete över kommun- och regiongränser. Kärnvärdena som Kattegattledens samarbetsparter definierat är: havsnära, variation, välkomnande, trygg och säker samt upplevelserik.

Planering  av  hamnområdet  i  en  sommarstad : en  fallstudie  i  Båstad

Det här är en studie kring ämnet flexibel utformning av offentliga rum, och ett förslag på hur Båstads hamnområde skulle kunna utvecklas till en plats som på ett mer tillfredsställande sätt kan användas året runt. Idag är hamnen en plats som präglas av några månader med intensivt liv och mycket rörelse under sommaren, för att sedan bli en tom och oanvänd plats vintertid. Förslaget har föregåtts av analyser, både under vinter och sommar, av hamnens rumslighet, aktivitet, rörelse och attraktioner, en litteraturstudie kring ämnet flexibel utformning av offentliga rum, samt två studiebesök på mindre orter i Sverige som kämpar med en liknande problematik. Förslaget har också föregåtts av en inventering av området, samtal med tjänstemän på Båstads kommun och näringsidkare i hamnen samt studier av tidigare planprogram och planer för hamnen framtaget av kommunen. Med utgångspunkt i resultaten av analyserna och med inspiration från litteraturstudien och studiebesöken har jag tagit fram ett förslag på hur Båstads hamnområde skulle kunna utvecklas, göras mer flexibelt och därav mer användbart hela året.

Konkurrenssituationen för den skånska grönsaksproduktionen :

The vegetable production in Sweden is concentrated to the very southern parts of the country. This is also were the major wholesalers are located. In recent years, there has been an extreme focus on price on the food market. As there are only a few big wholesalers and also very few food retail chains, these have a great impact on the producers. The pressure from prominent vegetable-producing countries, providing low price products, such as the Netherlands and Spain is strong.
