Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus
Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.
Vingårdar i Sverige! : farligt för miljön?
The future climate of Sweden is expected to become warmer in the future. This would be beneficial for vineyards and may lead to a greater area being allocated for wine production. The environmental impact concerning eutrophication from Swedish vineyards has not been evaluated before. In this study nutrient balances are constructed for four Swedish vineyards with the goal to estimate the out and in flows of nutrient in the systems for the year 2010. Interviews with focus on farming practices undertaken during the year are conducted with the farmers.
Äter Mellanskarv i Sommen det unika beståndet av röding och öring?
Detta är ett naturvetenskapligt arbete som omfattas både av en kvantitativ och en kvalitativ undersökning. Syftet med arbetet är att undersöka mellanskarvens födoval i sjön Sommen, samt att närmare studera huruvida det unika beståndet av röding och öring ingår i mellanskarvens födoval. Sommens Fiskevårdsområde har fått tillstånd till skyddsjakt på mellanskarv av Länsstyrelsen och det främsta skälet skulle vara att fågeln prederar röding och öring. Genom att analysera mellanskarvens spyboll och jämföra innehållet med referensfiskar fångade från samma sjö ska vi se om beslutet från Länsstyrelsen är befogat. Insamling av spybollar och referensfiskar utfördes i fält medan analys av spybollar utfördes på laboratorium.
EU-stöd inom fårproduktion på Öland jämfört med Småland/fastlandet :
The Sheep is the oldest livestock, and has been in Sweden for 4-5000 years. Thanks to that you can obtain skin, as well wool and meat. Therefore it was an important animal. Sheep production has increased, strongly lately due to the pasture support.
The purpose of this paper is to find out what kind of different EU-subsidies you can get and to compare the subsidies in Öland and the main land.
Sheeps are very good conservationist with grass, bushes and herbs, because of different grazing lands hardness and growth is it important to control the pasturage strain. A good way to regulate this is to have different enclosed pasture to switch between.
I have been studying the different EU-subsidies.
Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :
This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.
Kampen om ett föränderligt Arktis : En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.
The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to competition and cross-border strife among the Arctic States. The two largest states in the Arctic are Russia and Canada, which are also members of the Arctic Council. Russia and Canada are at the moment involved in several disputes regarding the Arctic territory where the ownership of the North Pole is one example.
Follikulärt microbiom hos friska individer : Detektion av bakterier och svamp med in situ hybridisering och immunofluorescens
Bakgrund: Det är viktigt att främja barns fysiska aktivitet, eftersom det leder till många positiva hälsoeffekter. Tyvärr är många små barn idag inaktiva och når aldrig den rekommenderade gränsen på 60 minuters fysisk aktivitet per dag. Syfte: Att beskriva hur fysisk aktivitet kan främjas bland barn, i åldrarna 2-8 år. Metod: Studien som utfördes var en litteraturstudie där tio vetenskapliga artiklar granskades. Resultaten sammanfattades genom att söka meningsbärande enheter och därefter skapades teman av dessa.
Controlled Traffic Farming i skånsk växtodling
Hur vi uppfattar vår omgivning påverkas av alla våra fem sinnen, där denna uppsats tar sin utgångspunkt i hörseln och det vi hör. Utifrån en litteraturstudie och egna reflektioner har ljuds betydelse och hur det påverkar oss i det dagliga livet undersökts. Syftet har varit att öka förståelsen för vad ljud betyder för vårt välbefinnande och hur vi som landskapsarkitekter kan ha ljudet i åtanke när vi gestaltar utemiljön.
Ljud är mer än den fysiska ljudvågen. Det kan ge oss information om vår omgivning, spegla rörelser, underlätta orienterbarheten och vara en del av hur vi uppfattar rumslighet. Vi hör hela tiden, men lyssnar inte alltid medvetet.
Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms
This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.
Ett liv med figurer : En utställning om minnen och föremål
This thesis is based on an exhibition at the county museum Upplandsmuseet in Uppsala, Sweden. During an internship at this museum I got a chance to produce an exhibition, with some guidance from the museum staff. This exhibition was created with the purpose of teaching about agriculture in the late 19th century and also about the magnificent workmanship of Alrik Klingberg, who have carved these wooden objects for over 50 years. Each one of the objects possesses a story and a memory. The memories that Alrik Klingberg has incorporated into the objects are mainly from his childhood at a croft in northern Uppland.
Vivesholm : djurbenen belyser den gotländska medeltida borgens husdjurshållning samt husgrundernas användningsområden
The castle Vivesholm is located about two miles north of Klintehamn on the west side of Gotland. The castle was built around year 1395 and burned down in the end of the 14thcentury. Around the 17th and the 18th century the castle was re-used. However, the emphasis on its use is during the middle ages.This paper aims at getting an insight in the animal husbandry at Vivesholm by analyzing the osteological material. The analysis revealed that bones from sheep/goat were more common than bones from cattle.
Trastuzumab som adjuvant behandling avbröstcancerpatienter med HER2-positivitet : Hur effektivt är det?
Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
Framtidens avloppsvattenreningsverk ? en modern energiproducent : En fallstudie av Himmerfja?rdsverket
In a sustainable society the use of renewable energy and recycling of materials is of high importance. Wastewater treatment plants use large amounts of energy in the processing of wastewater. This study seeks to evaluate wastewater as an energy resource and to examine treatment plants potential to become sustainable energy producers. The study is based upon the internal processes of Himmerfja?rdsverket.
Local stakeholders? willingness to conduct actions enhancing a local population of Grey Partridge on Gotland ? an exploratory interview study
The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.
