Alléers användning genom tiderna i Sverige : en bakgrund till alléns framtida utveckling
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Isbjörnars (Ursus maritimus) interaktioner och hägnutnyttjande på Orsa björnpark
SAMMANFATTNINGIsbjörnen är mycket populär hos djurparksbesökare och en viktig symbol för klimathotet, trots detta finns fortfarande många frågetecken kring hur vi ger isbjörnar i djurparker hög välfärd. I litteraturen har vi länge talat om isbjörnar som solitära djur men trots detta låter vi dem ofta dela hägn med andra isbjörnar på djurparker. Det har observerats positiva effekter av grupphållning av isbjörnar, bland annat sänkt förekomst av stereotypa beteenden, men vi måste vidare utreda vilken påverkan det har på deras välfärd. Ytterligare problem för isbjörnar på djurparker är stereotypt vankande som har observerats hos flertalet karnivorer som i det vilda rör sig över stora områden eller hemytor. Syftet med denna studie var att titta på hur isbjörnarna på Orsa björnpark utnyttjar sitt hägn, vilka beteenden som kan observeras samt hur stor del av observationerna de spenderar tillsammans.
Kan risken för spontan contortaföryngring elimineras genom hyggesbränning? :
Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
Glycerol to dairy calves : effects on intestinal health and fluid balance
The bacterium Lactobacillus reuteri, which natural habitat is in the intestine of mammals and birds, uses glycerol as a substrate for production of the antimicrobial compound reuterin. Glycerol has been shown to decrease the number of Escherichia coli in human feces and it is believed to be due to in situ production of reuterin. E. coli belongs to the large family of Enterobacteriaceae, naturally occurring in the intestine, and pathogenic strains of E. coli have been shown to be one of several bacteria causing diarrhoea in calves.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Gremmeniella abietina-epidemin 2001 : har skogen återhämtat sig?
The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.
Tabloidiseringstendenser - i det redaktionella innehållet
The daily newspaper market in Sweden has been a mighty strong media market, except for major market crisis which occurred in the 1990s in Sweden, that led to several newspapers came into an economic crisis. One of the actions that many Swedish newspapers did was to reduce the physical size of the newspaper from broadsheet to tabloid. After studying several academical studies from scientists and students who claim and show in their results that the tabloid tendencies has spread out in the editorial content I discovered that the common thing for these studies where firstly, that there were not many studies that showed the tabloid tendencies of the editorial content in a longer historical perspective, secondly that the studies jointly studied tabloidization tendencies (how the editorial content changed from writing about hard news to write about soft news) in the editorial content of newspapers that have changed the physical format size. The material that was analysed was tabloid tendencies in news articles in two daily Swedish newspapers, Jönköping-Posten (broadsheet) and Aftonbladet (tabloid) in the years 50s, 60s, 70s, 80s and 90s. The goal was to see if or how much of the editorial content of news articles that changed over time by tabloid tendencies in individual daily newspaper as well as a comparison of the various newspaper formats.This lead to the purpose of this master study:To investigate if it exists tabloid tendencies in the editorial content of news articles in the Swedish newspapers Aftonbladet and Jönköping-Posten between the 1950s to 1990s.In addition this purpose was operationalized from theories of tabloidization, the main theories that are used in this master study is developed by the researchers Shelly McLachlan and Peter Golding and their definition for tabloidization range, form and style.The best tool to analyse the material that have been gathered was to use of quantitative content analysis.
Varumärkesutvidgning ? En viktig komponent i företagens affärsutveckling
Syfte: Syftet med studien är att analysera och beskriva hur ett företag kan arbeta med varumärkesutvidgning samt identifiera framgångsfaktorer, motgångar och bakomliggande orsaker som kan förekomma vid en varumärkesutvidgning.Metod: Vår studie utgår främst från den kvalitativa metoden. Inledningsvis presenteras ett ramverk för lämplig teori för att vidare kompletteras med intervjuer. Den empiriska delen består av kvalitativa intervjuer med företagen King Salming AB, Salming Sport, Peak Performance, Björn Borg och L`Homme Rouge. Slutsats: Vi har funnit stöd i, att teorin som avser varumärkesutvidgning kan användas i verkligheten. Samtliga bolag följer en varumärkesstrategi där kärnvärden och territorium utgör basen för en varumärkesutvidgning. I de fall där varumärkesutvidgningen inte fungerat som tänkt är det också avståndet till kärnvärdet och territoriet, som är ett av det återkommande problemet.
SARS
SARS [Severe Acute Respiratory Syndrome] penetrated China in spring of 2003, created havoc in the social society, exposed weaknesses within the political system and pushed the nation towards a crisis of confidence. At the same time the crisis revitalised the Party's position, brought people from different social stratum together and had a beneficial impact on the populace's knowledge on health related issues.What makes the SARS crisis in China interesting for further and deeper investigation is the method it chose to respond to its national crisis. They plan of response was indeed a retrogression back to "older" times, using methods and propaganda very much like those used during Mao Zedong and later Deng Xiaoping. The first step of response was denial and cover up of the real situation, which quickly turned to unprecedented transparency, as the magnitude of SARS became known. The Party and the government were quick to proclaim themselves as the bearer of the key knowledge and information on how to best fight the disease, this in sharp contrast to the political trend of more co-operation between the private and public sector and political transparency.
Bergerosion i utskovskanaler
Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.
Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia
Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity.
Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.
Örtagårdsparken i Rosengård : tillbakablick och framtidsperspektiv
Malmö Kommunala Bostadsbolag Fastighets AB owns and administrates Örtagården housing estate in Rosengård which is a characteristic million programme housing area. Örtagården is densely populated which naturally creates an environment that is exposed to wear and tear. The area is today undergoing a change where new proposals and strategies are to be designed for further development of the inner yards. MKB also wishes to develop the park area which is centrally situated in Örtagården. The purpose of this study was to make an analysis of the development of Örtagårdsparken from when it was planned and constructed up until the state it is in today.
I en värld av makroekonomisk osäkerhet - En scenarioanalys kring ränte- och inflationsförändringars inverkan på ett fastighetsbolags fria kassaflöde
Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.
Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]
Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.
Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län
Burnt alun shale and lime is the residual product that was formed when alun shale was
used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium,
molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this
paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale
and lime to determine whether or not the surrounding environment and humans are
exposed to these elements by eating plant products.
A cultivation trial was carried out where onion, carrot, and lettuce were grown on three
mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments
were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a
reference soil. The reference plots were natural soil mixed with peat adjacent to the
mounds.
