Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment

Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Tvång som vård : Patienters upplevelser av tvångsvård och tvångsåtgärder ? en litteraturöversikt

Background For patients in need for psychiatric care who refuse treatment, coercive care might be necessary due to The Law of Psychiatric Compulsory Care, LPT. The purpose of this law is to make sure the patient later on will be able to increase autonomy. The most frequent patients in coercive care suffer from psychosis, heavy depression or having high risk of committing suicide. One of the most important tasks in the nurse profession is to increase patients? autonomy.

Hur påverkas bentiska funktionella födogrupper av kalavverkning? : Effekt på abundans, samt återhämning, av funktionella födogrupper efter kalavverkning kring små vattendrag.

Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.

Det relativa värdet av ämnesingångar i databaser: Variationer mellan discipliner

This thesis deals with tactics for information seeking in electronic databases. An important aspect is knowledge of the relative value of different subject access points. The method used here is literature studies. Nineteen empirical studies are described and analysed with the purpose to compare the relative value of different subject access points. The studies examined compare the relative value of subject access points in relation to each other or in relation to different scientific disciplines.

SAMMANS?TTNING AV MAKROALGER I SVENSKA ?LGR?S?NGAR eDNA sp?rning och klimatf?r?ndringar

The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the distribution of filamentous algae as well as the general species composition of macroalgae and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been on linking these changes to climate change factors such as eutrophication, temperature increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows and their ecosystem services, such as a carbon sink and biodiversity support. The results show that filamentous algae have increased markedly in coverage in Swedish coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered environmental conditions favor these fast-growing species. Genetic tracking using eDNA demonstrated that there are functional primers for many species, particularly among brown algae and red algae, whereas green algae require more specific primers due to greater genetic variation.

Övertoner i elnät vid Skellefteå lasarett : Harmonics in power grids at Skellefteå Hospital

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Illustrationens roll i läromedel inom matematikämnet : En studie av matematikläromedel för årskurs två mellan åren 1960-2010

Denna studie behandlar illustrationer inom matematik. Fokus har varit att undersöka vilken roll illustrationer spelar i samband med subtraktionsuppgifter för elever i årskurs två. Detta genom att studera olika matematikläromedel. Studiens område sträcker sig från 60-talet fram tills idag, år 2010. Inom dessa decennier har två matematikläromedel per decennium slumpmässigt valts ut för analys.

Det sociala ansvaret i skapandet av skönhetsidealen

Kandidatarbetet undersöker och diskuterar frågeställningen "Vilket socialt ansvar har jag som grafisk formgivare i skapandet av skönhetsidealen?". Kandidatarbetet fokuserar på att skapa en diskussion kring ämnet skönhetsideal, hur dessa påverkar unga kvinnor samt vilka möjligheter det finns för att bryta samhällsnormer och göra en förändring, en större skillnad. Utifrån mitt forskringsresultatet kring skönhetshistorian och dess utveckling under åren, har jag skapat en produktion i form av modeillustrationer. Jag tycker inte att samhället inser hur kraftfullt påverkade vi har blivit av media och modebranschen under de senaste åren. Även de som inte är intresserade av mode och skönhet. Vi som jobbar inom medie- och reklambranschen är den tredje statsmakten.

Produktionskalkyler för biobränslen :

This study is one of five that has been done based on Lunds Energi?s planned investment in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be supplied with biofuels. In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage sludge.

Prim, Stadsförnyelse i Barcelona

This final project discusses renewal and upgrading of the area of Prim. It is discussed how this industrial area can be an attractive neighborhood with a varied range of services and commercial trade. Prim is located 2km north-east of the center of Barcelona. The area boarders to a deep railway valley that historically has separated Prim from its neighboring districts. At present there is almost no housing, services or commercial trade within the area and the industry is discontinued or the existing industrial buildings are derelict.

Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?

Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

Spawning site selection of brown trout in habitat restored streams

During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.
