Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Imageination: En uppsats om imageöverföring inom sponsring och Event Marketing

There are two main reasons for why companies engage in sponsoring and Event Marketing; affecting the brand awareness and/or the image of the brand. Historically the main focus within the research field has been on how sponsoring and Event Marketing can create and achieve high brand awareness. More research regarding the image transfer from event to brand has been requested and this study is to be considered as an attempt to begin filling this gap. Today we see more and more brands choosing to arrange their own events; hoping to attain a more direct connection between the event and the brand. This trend raises questions such as - Do brands arranging their own events receive more image transfer from event to brand compared to brands sponsoring the same kind of event? - Are there any differences between an established well-known brand and a new unknown brand? - Will an event fully owned by a brand attract more or less people than an event arranged by someone considered to be less biased? These are some of the questions asked and answered within this thesis.

Stress, self-efficacy och livstillfredsställelse : Finns det köns och åldersskillnader

ABSTRACTThe aim of this quantitative study was to investigate if stress, self-efficacy and life satisfaction varied with gender and age. The sample was selectively chosen in the municipality, country council, private sector and in the trade business. 237 participants were included in the study, of which 94 were men and 143 were women. Age was split in two categories: younger adults (18-40 years) and older adults (41-65 years). The results showed that there were correlations between the dependent variables: stress, self-efficacy and life satisfaction.

Kalkningens påverkan på fosforlöslighet : skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

Effekten av Valutarisk på Bilateral Handel

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

Har energidryck någon kognitiv effekt i kombination med alkohol? : Med fokus på komponeneten koffein

Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.

Genomförandet av beslutat umgänge inom EU och utanför : Skyddet för barns kontakt med sina föräldrar

Vi lever i en tid då människor är mer rörliga över landgränser än någonsin förr. Detta får till konsekvens att det blir allt vanligare att människor har kopplingar till flera länder på olika sätt. Det blir också vanligare att personer av olika nationaliteter och ursprung gifter sig och skaffar barn tillsammans med följden att det blir vanligare att familjer efter en separation har anknytning till flera stater.Denna uppsats undersöker hur olika internationella instrument försöker skydda barns rätt till kontakt med sina föräldrar när de bor i olika länder. Vidare diskuterar uppsatsen hur och under vilka omständigheter umgängesdomar som beslutats i en stat kan verkställas i en annan stat. I detta syfte undersöks flera internationella instrument, men fokus ligger på Bryssel IIa-förordningen, 1980 års Haagkonvention och 1996 års Haagkonvention.I uppsatsen konstateras att hur verkställigheten av en dom i Sverige sker beror på i vilken utländsk stat domen har utfärdats och det konstateras att de olika instrumenten är olika effektiva vad gäller att verkställa en umgängesdom.

Lugnet före stormen : En studie om hur Räddningstjänsten Medelpad arbetar med kommunikation och planering innan en kris

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

FINANSKRIS Vilka regleringsfrågor med fokus på redovisningen har identifierats i samband med finanskrisen kopplat till finansiella instrument?

BAKGRUND OCH PROBLEMDISKUSSION: Världen befinner sig i en djupgående krissom inte har upprepats sedan depressionen under 30-talet. Varje kris har en utlösande faktoroch även denna gång började det i USA. Under år 2008 började oron växa sig kraftig sedanstora aktörer på den amerikanska finansmarknaden drabbats av förluster och stagnerandebörskurser. När Lehman Brothers kollapsade under hösten år 2008 kulminerade oron till renpanik på finansmarknaden som spreds världen över nästan omgående. Problemet är attkreditmarknaden har upphört att fungera då riskexponeringen är okänd bankerna emellan ochövriga intressenter, vilket har resulterat i att ingen vågar låna till någon.

Elitdressyrryttares visualiseringsupplevelser samt deras förståelse och upplevelse av instrumentet the Survey of imagery experiences in sport

Blakeslee och Goff (2007) föreslår att dressyrryttares visualiseringsfärdigheter bör skilja sig från andra sporter som inte involverar ett djur. Enligt Murphy, Nordin och Cumming, (2008) finns det ett behov av ett instrument som tar hänsyn till visualiseringstyp, funktion och dess utgång. The survey of imagery experiences in sport (SIES; Weibull & Wallsbeck, 2009; Wallsbeck & Weibull, 2009) är ett relativt nytt instrument som mäter dessa variabler. Syftena i denna studie var därför att: (1) studera elitdressyrryttares visualiseringsupplevelser, (2) studera elitdressyrryttares förståelse och (3) upplevelse av instrumentet SIES. En kombination av kvalitativ och kvantitativ metod användes i studien.

Restaurerade ängs- och betesmarker : restaureringseffekten på växter och insekter

Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants. By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.

Kvinnlig representation och dess substantiella effekter En studie om svenska kommuners flyktingmottagande utifrån ett könsperspektiv

Municipalities with a higher amount of female representatives has been shown to be more gender equal. Earlier reasearch has also shown that female politicians are more likely than male politicans to represent immigrants and refugees interests. However, the effect of female representation has not been tested on other subordinated groups than women. Swedish municipalities have full autonomy regarding refugee reception and local politicians are responsible for the decision on the amount of refugees that the municipality accept. The variations of female and male politicians in the local assemblies are expected to have different outcomes on the refugee reception, according to females social backgrounds and experiences.

Läsa med självförtroende : En fallstudie om hur lärare arbetar för att motverka Matteuseffekten

The aim of the study is to investigate how a teacher and a special education teacher cooperate to prevent a pupil with reading difficulties from ending up in the vicious circle of the Matthew effect, and to find out how a pupil with reading difficulties experiences his or her reading situation. This case study is based on a phenomenological perspective whereby qualitative interviews illuminate a commonly occurring problem in today?s schools. Interviews were conducted with a teacher, a special education teacher, and a pupil in grade 1, in order to cover everyone?s perspective in this situation.

Behov av akut datortomografi och medicinska a?tga?rder hos patienter med strokesymptom och/eller medvetandepa?verkan ? Go?r ambulanssjuksko?terskan och medicinla?karen samma bedo?mning?

Postoperativ återhämtning är en viktig del när patienten genomgår ett kirurgiskt ingrepp. Efter operation vårdas patienten för rehabilitering samt för observation och behandling av eventuella anestesiologiska och/eller kirurgiska komplikationer. Som ett resultat av utvecklingen av anestesiologisk och kirurgisk teknik (till exempel minimal invasiv kirurgi och standardisering av operationsmetoder) har den postoperativa vårdtiden på sjukhuset minskat. Genom denna effektivisering så minskar kostnaderna och fler patienter kan opereras inom kortare tid i jämförelse mot tidigare.Författarna till den här studien arbetar på en kirurgavdelning där patienter vårdas som bland annat har genomgått kolorektal kirurgi. Uppföljning av patienternas postoperativa återhämtning på avdelningen sker enligt fasta kliniska rutiner genom till exempel kontroll av kroppstemperatur, blodtryck, andning, smärta och magtarmfunktion.
