Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.
Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland
Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.

Fr?n rapportering till transformering: H?llbarhetskonsulters perspektiv p? CSRD:s potential till h?llbar verksamhetsomst?llning
Humanity faces a major challenge with the climate and environmental crisis, largely driven by
reckless recourse use and greenhouse gas emissions by corporations. The EU?s Corporate
Sustainability Reporting Directive (CSRD) aims to standardise corporate sustainability
reporting, making practices more transparent and comparable. This directive seeks to enhance
sustainability practices and guide market forces towards sustainability, supporting the EU?s
goal of net-zero emissions by 2050.

Attityder som motstånd i implementeringsprocessen : Förvaltningschefers föreställningar om behov och resurser för jämställdhetsarbete
ABSTRACTEssay in political science, C-level by Cecilia HolmbergSpring semester 2006, Tutor: Arne Larsson- Ideological similarities between the Swedish Socialdemocratic and the Swedish conservative party- An idealanalysis of different political issuesThe purpose of this essay is to examine wheater the political ideologies have lost their importance in the Swedish political system. The study will focus on the ideological similarities or differences between the two largest parties in Sweden, the socialdemocratic and the conservative party. Therefore, the main research question is:? Are there any ideological similarities or differences between the socialdemocratic and the conservative party?To be able to answer this question, I have used Herbert Tingsten?s idealanalysis. This type of analysis examines how someone, in this case a political party, describes reality.
Ungdomars egna upplevelser om relationerna till sina föräldrar : ?Det finns inget härligare än att jag står så nära mina föräldrar? Sandra, 14 år
Syftet med detta examensarbete har varit att undersöka hur ungdomar upplever betydelsen av sina föräldrars engagemang för ungdomarnas eget välbefinnande. Hur tillgängliga upplever ungdomarna att deras föräldrar är; hur upplever ungdomarna deras samspel med föräldrarna och hur upplever ungdomarna det sociala stöd de får från sina föräldrar? I studien har åtta ungdomar intervjuats om hur de upplever sina föräldrars engagemang och samspel. Av intervjuerna har det bland annat framkommit att samtliga ungdomar ville spendera mer tid med sina föräldrar, att de ville ha möjligheten att prata med sina föräldrar om allt och att de gärna gjorde saker tillsammans. I diskussionen dras slutsatser att ungdomarna i denna studie upplevde att de mådde bättre om de hade möjligheten att pratar med sina föräldrar.
Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi
AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.
En bibliometrisk underso?kning av bibliometrins utveckling : Underso?kning av hur publikationen av bibliometriska, informetriska, scientometriska och webometriska artiklar har utvecklats sedan 1960- talet
The main purpose of this bachelor thesis is to analyse the publication- and citation patterns of the articles concerning bibliometrics, informetrics, scientometrics, and webometrics which can be found on Web of Science, and give a brief description of how the definition of the four terms has developed. I have looked at how the number of published papers have developed over the years and to what extent they have been quoted by other researchers. I have also briefly adressed what other research fields are referring to articles published in the four areas. The material I looked at includes articles that can be found on Web of Science with one (or more) of the four terms as topic and are categorised under library- and information science starting with the first bibliometrics article which was published in 1969, and ending in 2013. The results show that the publications in all four fields are continuously increasing.
Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)
Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to
impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in
deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate
deciduous forest.
Polletten har inte trillat ner, ännu? Bankernas hållbarhetsredovisning håller inte måttet!
The voluntary none-financial sustainability report has become a trend within accounting. The environmental issues used to be driven by activists only, but lately it has moved in to the general agenda in many companies. Investors are starting to put more attention to the sustainability reporting as it is considered to add value to the company. There are several standard guidelines to be used when producing a sustainability report, one example is the GRI´s Guidelines that takes the following three dimensions in consideration: economy, environment and social. This Guideline is from an international perspective considered to be of good accounting practice (Ljungdahl 2008).
De blir fria i tanken : En kvalitativ studie om pedagogers tankar om pedagogisk dokumentation
This MA thesis analyzes how the protagonists and the narrative structure relates to ?the Child? as a linguistic/cultural construction in Mare Kandre?s early authorship (1984-1991). A thematic of children portraits defines this period of Kandre?s writing, which consits of the following works: In a Different Country (1984), The Annunciation (1986), Bübin?s Kid (1987), The Burning Tree (1988) and Aliide, Aliide (1991).Linguistic components, such as the word ?child?, the name ?Kid? and a reconstruction of the concept of childhood, holds an actuate position in these narratives when they first appear in direct relation to the protagonists. This suggests how generally accepted categories and concepts consciously are at work in Kandre?s writings.
Renovering av Gamla Årstabron med injekteringsbetong
Gamla Årstabron i Stockholm uppvisade efter 80 år i drift omfattande skador på de bärande betongkonstruktionerna enligt en utredning som genomfördes 2006 av dåvarande Carl Bro AB på uppdrag av dåvarande Banverket Region Öst. Det konstaterades att omfattande reparationer och förstärkningar av brons betongvalv var nödvändiga för framtida rationell drift av bron. Det beslutades efter vidare utredning att de första tre valven på Södermalm i Stockholm skulle renoveras med injekteringsbetong. Renoveringen av de tre valven på fastlandet på Södermalm var ett prov i full skala för att hitta den optimala metodiken för den fortsatta renoveringen av resterande 17 betongvalv. Det här examensarbetet syftar till att utvärdera metoden med injekteringsbetong med hänsyn till injekteringsbetongens egenskaper, material och produktionsteknik. Bakgrunden till detta examensarbete är att det finns ett stort behov av att följa upp renoveringsmetoden med injekteringsbetong eftersom den inte har använts i någon större utsträckning i Sverige sedan slutet av 1970-talet.
Informationskompetens i Tyskland och Sverige : En jämförande studie av användarundervisningen vid två högskolebibliotek
This master?s thesis studies library teaching at two university libraries, Freie Universität Berlin in Germany and Södertörn University in Sweden. The aim of this paper is to study views on information literacy, how these views affect teaching practice, and how the teaching of information literacy is connected to, on the one hand, German and Swedish learning culture and, on the other, the local community of practice at the studied university libraries. The theories applied in this paper are learning culture and community of practice as developed in the works of Judith Ricken and Etienne Wenger. The methods that have been used are qualitative, semi-structured interviews that were conducted at both university libraries.It was observed that the teaching practices were highly connected to learning cultures.
Slöjdens mening och nytta : För eleven i grundskolans senare år
Syftet med studien var att förstå betydelsen och nyttan av slöjdämnet i grundskolanbetraktat genom elevers berättelser om ämnet.De frågeställningar som jag utgick ifrån var:· Vilken karaktär av kunskaper uttrycker eleverna att slöjdämnet leder till?· Vilken mening och nytta uppfattar eleverna att slöjdämnet har?Litteraturavsnittet tar upp slöjdämnets historia, tillkomst och förändring fram till dagenskursplan och läroplan. Vidare tas kunskapsbegreppet upp utifrån läroplanen, Aristotelesfilosofi samt Vygotskijs sociokulturella teori.Den andra delen av litteraturkapitlet behandlar slöjdämnets kompetenser såsompedagogisk process, kropp och kommunikation samt entreprenöriellt lärande.Elevers dagboksanteckningar samt deltagande observationer utgjorde data. Deslöjdkompetenser som eleverna gav uttryck för och som jag såg i mina observationervar entreprenöriell kompetens, kroppslig och kommunikativ kompetens,processkompetens samt en känsla av lust.Resultatet visade att den betydelse och nytta eleverna tillskriver slöjdämnet är desskaraktär av konkretion samt av engagemang och delaktighet.I diskussionen kopplas litteratur och resultat ihop med egna reflektioner. En av defrågor som studien bidrog till är hur och om de praktiska och estetiska ämnena kan sessom utgångspunkt för mer teoretiska ämnen? Mot bakgrund av studiens resultat kan detfinnas outnyttjade möjligheter att dra nytta av slöjdämnets fördelar inom andra ämnen..
