Vattensork och åkersork - skadegörare i svensk fruktodling

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

A systematic overviewAuthor: Irene Eriksson and Alexandra ÖquistSupervisor: Henriette PhilipsonExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: During physical exercise, it is common with dehydration, which affectsperformance negatively. To restore the fluid balance it is optimal to drink fluids containingsalt and carbohydrates. In theory, coconut water should be a good recovery drink because oftheir nutrient content.Objective: To evaluate the scientific evidence available, to investigate whether coconut wateris better than water or sports drinks for rehydration after physical exercise.Search strategy: PubMed, Scopus and Cochrane Library have been used in the literarysearch. Keywords used were recovery, fluid balance, fluid therapy, water-electrolyte balance,rehydration, dehydration, hydration, exercise, physical activity, resistance training, activity,sports, training, coconut water in varying combinations, in order to cover as wide area aspossible.

Käppalaverkets nuvarande och framtida rötningskapacitet : en studie i labskala

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Lojalitetsprogram ur medlemmarnas perspektiv. : Skapas lojalitet eller tröghet?

As the usage of loyalty programs increases, this study takes a new approach to examine how these programs influence consumers? attitudes toward brands. This paper is influenced by the recent findings that question the capability to create a clear picture of the effects of loyalty programs by conducting quantitative research. This is based of the differentiation between attitudes and actions, leading to the fact that quantitative research have only captured the actions of members of loyalty programs. In contrast to that, this paper uses qualitative interviews to create a more in-depth point of view.The paper immerses the reader in the theoretical viewings of what loyalty is and how it emerges from satisfaction.

Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark

This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

En ?terinventering och analys av den svenska populationen av svart nervmossa (Campylopus atrovirens)

Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.

Titel: Franchisee-based brand equity inom fastighetsmäklarbranschen ? Varumärkets värde för franchisetagare Nivå: C-uppsats i ämnet företagsekonomiFörfattare: Ebba Granberg, Malin BloomHandledare: Jonas KågströmDatum: 2015 - majSyfte: Syftet med denna studie är att analysera vilka källor franchisetagare påverkas av i skapandet av FBBE inom tjänsteföretag. Detta med avseende på vilken betydelse varumärket har i franchisekonceptet och huruvida detta påverkar franchisetagarens intentioner att ingå i ett franchiseavtal samt bibehålla franchiserelationen.Metod: Då syftet med studien är att analysera franchisetagarens påverkan av FBBE, har således studien genomförts med en kvalitativ forskningsansats. Semi-strukturerade intervjuer har utförts med 12 franchisetagare inom fastighetsmäklarbranschen, vilka alla arbetar i Stockholmsområdet. Materialet har därefter analyserats med hjälp av dataanalysprogrammet Nvivo10 och presenterats tillsammans med resultaten för studien.Resultat & slutsats: Studien introducerar en ny modell över FBBE inom den svenska fastighetsmäklarbranschen.Förslag till fortsatt forskning: Denna studie är avgränsad till ett specifikt geografiskt område och det kan därför vara av intresse att upprepa en liknande studien inom samma bransch, men i ett annat geografiskt område.

Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige

Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.

Produktivitet och kvalitet vid stickvägs- respektive beståndsgående förstagallring :

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

En upplevelsepark som stimulerar känselsinnet hos synskadade barn ? utformning och materialval

Abstract///// Parks and green spaces are important to a lot of people today. Are these parks made for us all? Is it possible for a person with a sight disability to explore and take part in all the things these places have to offer? They can probably take in some, but I think there are more effective ways of planning for the blind and sight disabled allowing them to explore using their tactile senses. The environment is vital for children?s development.

Slottsholmen på Svaneholm : en fallstudie om en historisk park- och gårdsmiljö och hur den kan ha tett sig under 16-1700-tal

The park at Svaneholm is a place, the history of which is very little known today and the needfor better knowledge has been the cause of this investigation. The essay is primarily limited tothe time from late 17th century up to the end of the 18th century and takes stand on profoundinvestigations in accessible map-and archive material. The results presented show a manorhill, which during the course of a hundred years was subject to several changes and in bigparts consisted in other than park/garden.Burman related to the manor hill containing a cowshed, a large dam and a parterre garden isix quarters and it is plausible to think, that this establishment generally was built as producedon the plate.In the 18th century the construction is being changed, they go on building at the cowshed andin 1707 there are totally 268 livestock on the farm. In 1723 the garden is represented in amuch bigger scale than on the plate from the 1680:s, but it is not possible to tell, whether it isnew or not.Parts of the parterre garden is remaining during the whole of the 18th century, for the leastuntil it is being squared, but on two of the squares there was built a riding-groundMoreover the cowshed burnt down and was only partially reconstructed.The image given by the archive material is at the same time variegated. The inventory list ongarden tools from 1726 gives an image of gardening more directed to growing and pathshuffling, while the possibilities of keeping the parterres were fewer (e.g.

Bildundervisning i Turkiet : med exempel från en skola i Istanbul

I meet in my work as art teacher many students of different descent, were they, or their parents, have different school experience than the Swedish. This, in combination with therecent discussion after the Muhammad caricatures about the banning of images in Islamic religion, made me curious to study what art education in a Muslim country looked like. I went to visit the Maramra Egitim Köyü school in Istanbul, Turkey, and especially their art classesfrom grade five to eight, which are the same age of students that I have been working with thelast ten years. This was my first visit to Turkey.The question I ask is: What does the practice of Turkish art education look like, using the Marmara school as an example. Which discourses can I identify in the art teacher practice? What surprised me the most was the frequent visual exposure of the founder of the Turkishstate, Kemal Atatürk.
